BACTERIOLOGY
KENDALL—Bacteriology, General, Pathological and Intestinal
New (2d) Edition
NE of the achievements of the Great War is a noteworthy advance in the Science
@ of Bacteriology. This is manifested not only in marked improvements in
methods of investigation and in modifications of preéxisting views in the im-
portant fields of Infection and Prevention of many diseases, but also in a complete
revision of some of the more important groups of bacteria. Prominent among these
is the great class of anaérobic bacilli. During the war period, furthermore, much addi-
tional information has accumulated pertinent to diseases which have hitherto been
elusive. These developments have necessitated the rewriting of entire sections of this
book, and extensive changes and additions to nearly every chapter. Indeed, including
the anaéGrobes and the work on spiral organisms, this new edition contains as much
as any volume in existence of the worth-while war and post-war work.
The text retains that characteristic which contributed so largely to the success
of its first edition, namely, dynamic interpretation of the subject. The author empha-
sizes throughout what bacteria do rather than what they are—how they get into the
tissues—what they feed on—what they excrete—how they multiply—how they escape
from the body—the chemistry of bacterial activity.
New methods of handling bacteria, methods which are improvements over earlier
ones, details of laboratory equipment, the minutie of technic and the use and value
of apparatus are carefully considered. Much space is given to the discussion of the
applications of bacteriology in Etiology and Preventive Medicine, as well as Serology
and the Vaccine treatment of disease.

THE SIGNIFICANCE OF CALCIUM
FOR HIGHER GREEN PLANTS}
In view of the time limit reasonably set for
this paper, I shall not attempt to review the
very extensive literature that in one way or
another deals with the relation of calcium to
the plant world, but shall content myself with
pointing out certain of the land marks that
occur at certain intervals along this oft-traveled
road. And, at the beginning, I may as well
give Jost’s summing up of the situation as he
saw it in 1906, when he says, “We are bound
to admit that its function has not yet been
discovered.”
To Salm-Horstmar*® seems to belong the
credit of proving in 1856 that calcium is neces-
sary for phanerogams and is distinctly not
replaceable by magnesium.
Almost -simultaneously in 1869 Adolph
Mayer 4 and Raulin® showed that this rule was
not of general application since certain non-
chlorophyllose types were found to thrive
without it.
Mayer grew yeast normally in media from
which calcium was lacking and Raulin did the
same with Aspergillus. It remained for
Molisch® in 1895 to demonstrate that not all
green plants require calcium by cultivating

certain alge in media from which this element
was absent.
In the meantime the distilled water problem
had arisen to vex all physiologists and in their
attempt to deal with it the zoologists had
thrown some light on the calcium problem as
well. Perhaps fundamental to all was the work
of the English physiologist, Sydney Ringer, who,
as a by-product of a long series of experiments,
developed the generally-used normal saline solu-
tion known by his name. While working on the
characteristic effects produced by various salts
in prolonging the life of organisms in water
cultures, he noted the favorable action of eal-
cium salts.. He observed that in distilled
water calcium and other salts were extracted
from fish placed in it, and records that epi-
thelial and mucous cells seemed to become de-
tached from the gills. In later experiments
earried out on Tubifex, a freshwater worm, he
noted that a far more striking change took
place. After a time spent in water from which
calcium salts were excluded, the worms dis-
integrated. When to distilled water a calcium
salt was added the worms not only lived but
behaved very much as they did in river water.®
His explanation of the fundamental causes
here operating was couched in rather general
language, but one gathers that he conceived
them to be of a physico-chemical nature, and
the seat of operation was thought to be in the
cells of the animals. There is much in Ringer’s
work to repay the student of general physi-
ology.
The fundamental features observed by him
were confirmed by Herbst in 1900°, when he
showed that in certain sea-urchin larve grown
in sea water from which Ca was lacking, the
epithelial tissues dissolved into their component
cells. When these dissociated, but still living,
elements were returned to calecium-containing
sea water, they adhered again to each other at
their points of contact., Herbst assumed that a
Verbindungsmembran exists between the cells

when Ca is present, that this membrane is dis-
solved when Ca is lacking in the external me-
dium, thus releasing the cells of the complex.
When Ca is restored, this membrane is recen-
stituted and again cements the cells at their
points of contact.
It is interesting to note in connection with
these observations of Herbst those of Kniid-
son,'° who found that in Pfeffer’s solution the
root cap cells of corn and Canada field peas
are sometimes sloughed and remain in the
medium isolated but living for as long a period
as seventy days or more. While it does not
appear that a Ca shortage existed in these
root cap eells, the possibility of such a shortage
would be well worth investigating.
In 1905 and 1906, while engaged in a study
of the physiological properties of distilled
water, the author, with the kindly aid of his
colleague, Dr. Lyman G. Briggs, applied the
method of electrical conductivity to the inves-
tigation of ion changes in solutions in which
seedlings were growing. It was observed that
the conducting capacity of distilled water in
which seedlings were grown increased, due, it
was believed, chiefly to the leaching of ions
trom the cells of the seedlings. It was noted
furthermore that this leaching was checked
when a small quantity of a Ca salt was added
to the distilled water.11
The use of the conductivity method was
extended by H. H. Bartlett and the author 2 to
a study of ion changes taking place in distilled
water and in solutions of calcium nitrate and
magnesium nitrate planted with pea seedlings.
Owing to the fact that the method as applied
to this type of work had not then been eare-
fully studied, more attention was given here
to the method. The conclusion was reached
that equilibrium concentrations of Ca and NO,
ions in one case and of Mg and NO,
ions in the other instance existed for peas
below which the roots would leach ions into

either solution, or into solutions containing
both salts mixed in various proportions and
above which the roots would absorb ions. It
was shown that Ca differed essentially from
Mg ions in being harmless in concentrations
that proved fatal in the case of magnesium.
The conductivity method was next applied
to the problem of absorption by phanero-
gamic seedlings from solutions of the ordinary
nutrient salts; these being studied singly in
various concentrations'® and mixed in a variety
of proportions and concentrations.‘14 I will
not try to deal here with the results gained
beyond presenting a brief summary of such
points as bear on the question now in hand.
As a result of the study of several sorts of
seedlings grown in solutions of single salts it
may be said that in solutions of potassium and
sodium salts no concentration was observed in
which the seedlings were able to carry on sus-
tained absorption, in the end yielding markedly
more ions to the medium than they were able
at any time to appropriate.
In solutions of Ca and Mg salts there was a
well defined equilibrium concentration below
which the roots were not able to absorb and
in these sub-minimal solutions ions leached
out into the medium. In solutions stronger
than this equilibrium concentration, absorption
took place in greater or less measure. It
appeared that Ca was more favorable gen-
erally than Mg. At no concentration tried,
the strongest being about 900 % 10—° gram
norm. per liter, was there any evidence of
injury. Where the concentration of Mg was
raised in order to ascertain the maximum
quantity of absorption, characteristic injury
appeared and death more or less promptly
thereafter. A similar injury appeared tardily
in weaker solutions on longer duration.
In mixtures again, absorption or leach de-
pended on the presence of Ca or Mg ions.
Again Ca in high proportion never brought
injury. Mg injury appeared less often than

in simple solutions. There was little evidence
that any such thing as a very definite Ca-Mg
ratio exists. In mixtures containing Ca and
other nutrient ions, especially when all or a
large proportion of the required ions were
present, the total quantity of ions absorbed far
exceeded the quantity of Ca ions present. This
indicated that in such mixtures Ca ions in
some way secured conditions that bring about
the absorption of ions, that, offered in unmixed
solutions, would be unabsorbed, or would cause
an active leach of other ions from the plant
cells.
Thus we may fairly say that the presence
of Ca ions in some way makes those absorbable
that would otherwise be unabsorbable and en-
ables the plant to retain ions that it would
otherwise be unable to retain. The Ca ions
may be truly said to make the others physi-
ologically available to the plant. Stating this
in terms of the soil, we may say that when the
required minimum of Ca ions is not present
in the soil solution other nutrient ions present
are largely out of reach and such a deficient
soil solution may finally leach mobilized nutri-
ents from seedlings. If the required minimum
of Ca ions is not present, other nutrient ions
may be present in abundance but be physi-
ologically unavailable because of the inability
of the plant to appropriate them.
Having thus far established the relation
between Ca ions and the ability of the roots
of the seedlings studied to retain ions gained
by the mobilization of their reserves and to
absorb others from the nutrient medium out-
side them, let us turn to a somewhat more
detailed study of this phase of calcium action.
Analytical data have long since indicated a
close chemical relation between the calcium-
content of higher plants and the cell wall.
The calcium content is relatively low in young
meristematic tissue and increases greatly in
those parts characterized by mature cell walls.
A more critical study of cell walls by Fremy,
Mangin, Bertrand and others has shown that
these are by no means homogeneous structures,
either chemically or structurally speaking, but
consist characteristically of an outermost layer
lying on the boundary line between adjoining
cells and other layers lying between it and the
4 SCIENCE
plasma membranes. This outermost boundary
layer consists of a calcium salt of a weak
organic acid known since work of Mangin as
pectic acid. .Not only is this structure Ca
pectate, but in cases other layers of similar
chemical character occur in the thickening
materials laid down in the more interior parts
of the wall. This Ca pectate has been shown
to be a stiff adhesive colloid that is formed
when pectie acid meets Ca ions. According to
authors from Fremy to Bertrand this acid
appears when the neutral mother substance
pectin is acted on by the enzyme pectase.
Now in view of the observations of Mangin,
Bertrand, and others, and latterly those of
Sampson !© there seems to be considerable free-
dom in the shifting of cell wal! materials into
and out of the pectic acid condition, and when
Ca ions are present, with the consequent ap-
pearance of calcium pectate layers. These
chemical shifts are frequently explicable only
by relaying them back to internal irritable
causes. They appear then in cases to be self-
regulated chemical responses to stimuli, per-
haps due in the first instance to external con-
ditions, but in their immediate application, to
internal causes. Thus Sampson finds in the
abscission tissue of coleus leaves following the
shock due to inflicted injury a change of more
or less of the cellulose of cell wall tissues to
pectic acid with a disappearance of calcium
ions from the cells of the abscission layers
and from their walls. Sampson favors the
view that the change of cellulose into pectic
acid arising from the irritation that sets in
motion the train of abscission phenomena is
responsible for the disappearance of Ca.
Pectic acid being present greatly in excess of
the quantity of Ca ions present can not be
converted by these ions into the firm colloid,
calcium pectate, but creates a thin, mechan-
ically weak colloidal medium which mutually
interdiffuses with the Ca ions and in _pro-
portion as the pectic acid exceeds the Ca
dilutes and removes it from its original seat.
In this connection it should be noted as a
general observation that the conversion of
cellulose into pectose is a usual feature in
16Sampson, Homer C., Bot Gaz., 66: 32-53. 1918.
[Vou. LV. No. 1410.
aging cell walls (Sampson: 48). The shift
from pectose to pectic acid follows easily.
The change in firmness of fruits and vege-
tables seen to follow the action of parasitic or
of saprophytie fungi seems to be a related
phenomenon. Here some form of Wiesner’s
theory of the generation of organic acids
which take possession of the Ca tied up in
health in the Ca pectate layers seems likely
to apply. With the removal of the Ca by acids
formed directly or indirectly by fungi, the
pectate layers become pectic acid or something
closely akin. Since these substances lack
mechanical strength, a slump of the tissues
follows. i
It was my good fortune to be able during
the winter of 1919-20 to associate Dr. Sophia
H. Eckerson of the University of Chicago
with our work on this caleium problem, then
being carried on in the U. 8. Department of
Agriculture and with her permission I beg
to refer here to some of her findings. She |
grew seedlings of wheat, maize and white
lupine in series of solutions closely paralleling
others that were receiving attention, or had
received attention in conductivity experiments.
Dr. Eckerson applied the methods of micro-
chemistry to the study of seedlings grown in
potassium solutions in which Bartlett and the
author had found a leaching of ions from the
seedlings unto the solution. Sbe observed
(1) that ions readily entered the cells of the
roots, (2) that within twenty-four hours Ca
ions began to diffuse out of the calcium pec-
tate middle lamella, (3) K pectate was formed
instead of the Ca salt and this substance being
relatively soluble in water soon dissolved,
(4) at this stage, sugars, amino-acids, and
salts, chiefly Mg, diffused rapidly out of the
roots. Thus we find Dr. Eckerson’s micro-
chemical evidence giving us the stages of an
event already found to exist by means of our
grosser conductivity work. It was established
beyond doubt that not only was the cell wall
modified and in part dissolved by the replace-
ment of Ca ions by K ions in the solution, but it
was shown that the damage goes far more deep-
ly into the cell. Analyses of the leach into dis-
tilled water by lupine roots has already demon-
strated to us that no less than two thirds of
JANUARY 6, 1922]
the materials yielded were organic and perhaps
in large part non-electrolytes. Dr. Eckerson
finds that the leach into K solutions are largely
organic and non-electrolytic. These solutions
must have come in considerable part from the
cell contents. The permeability of the cell
walls had been greatly modified, also the
osmotic properties of the plasma membranes.
These modifications were seen in the passing
of materials from within outward. Dr. Heker-
son tested the permeability in the opposite
direction. Corn seedlings after five days in a
KNO, solution were placed in a 1 per cent
solution of copper sulphate. In one hour the
Cu ions had penetrated all of the root tissue.
Similar seedlings after five days in a
Ca(NO,), solution showed the penetration of
Cu ions only after twenty-four hours in a
similar copper solution. This seems to make it
clear that permeability for ingoing ions is also
greatly increased by the changes that we have
‘described.
Experimental work on Mg solutions showed
that Mg pectate replaced Ca pectate in solu-
tions of Mg salts. It is known that while Mg
pectate is not soluble like K pectate and is
less permeable it is slightly more permeable
than the firmer Ca pectate-
Dr. Hekerson found in addition to this that
the fatal result repeatedly seen in our other
work to come after a longer or shorter time to
seedlings grown in Mg solutions of more than
minimal concentration did not occur until the
Ca of the middle lamella had been wholly
replaced by Mg. When this had come to pass
the cells died. We could perhaps imagine
that sufficient uncaptured Mg ions were then
free to penetrate the deeper structures of the
cell'to bring about the fatal upset.
The conclusion seems well founded that the
integrity of the calcium pectate forming the
middle lamella was maintained when a suffi-
cient quantity of Ca ions was present in the
culture solution and with it the normal reten-
tion of its contents by the cell. When accord-
ing to the laws of mass action this quantity
of Ca ions fell below the equilibrium concen-
tration, other kations present replaced the Ca
in the colloid compound forming the middle
dJamella. As a result of a long series of experi-
SCIENCE 5
ments in various culture solutions, it may be
said that no kation other than Ca has been
found that can replace it in this relation with-
out an injurious or fatal change seen in per-
meability relations, or without the appearance
sooner or later of other toxic response. Mg
comes most nearly to replacing Ca, but fails,
partly because of the greater permeability of
its pectate, chiefly because of the ultimately
toxie action of the Mg ions when they reach
the deeper lying structures..
In view of what has been said, what are we
justified in thinking concerning the phe-
nomena that lie deeper than cell walls, what
about the living content of the cell? I think
we are justified in regarding the cell wall and
the plasmal membranes that secrete it, and in
closest contact with which it lies, as standing
in the closest relation. Cell walls, except in
specialized locations, are seldom decisive in
determining what ions pass through them.
They influence, as we have seen, up to a cer-
tain quantity the ions that pass into them,
through the chemical changes which take place
in the walls themselves and thus far may be
regarded as having a certain quasi-deter-
mining influence. Beyond that, after chemical
demands in the walls have been satisfied, more,
deeply lying equilibria are concerned. As an
ion-containing structure, the cell wall main-
tains ion-equilibria subject to the laws of
equilibria in colloids, with the living mem-
branes with which it stands in most intimate
chemical and biological contact. When ion
equilibria in the wall are disturbed, this dis-
turbance is transmitted to the equilibria of
the protoplast that lays it down, modifies it
and remains in closest relation to it. Hence
it is not surprising that a drastic change in the
very chemical composition of parts of the wall
itself if continued should work through and
perhaps profoundly affect the equilibria of the
protoplasm.
This elose relation of protoplasm and cell
wall has already been seen in the eases of wall
change initiated from within in response to
irritation. When cells are melted apart by
self-regulatory processes it seems hardly neces-
sary to argue the intimate relation of wall
change to protoplasm change. In response to
6 SCIENCE
the formative laws governing the organism a
dozen or more layers of cells surrounding the
embryo of the wheat or maize are completely
absorbed and in the end the innermost remain-
ing walls of the ovary are literally cemented
to the outer unabsorbed layer of the inner
integument.!’ Here is emphatic control of cell
walls by the life inhabiting them, control ex-
erted chiefly through the ageney of the Ca-ion-
equilibria of the tissues concerned. Finally
this control in the wheat as in Herbst’s sea
urchin embryos is shown by the fusing together
of outer surfaces of cell walls. Here we seem
to have clean cut instances to show how in the
. formative processes the living material is able
to command the structure it forms about itself.
The outer walls of cells originally located far
from each other are brought together by the
solution of intervening structures. The sub-
stances necessary for the formation of the
cementing layer seem to be extruded from the
protoplasm through the wall to the outside
surfaces where they unite to form the coagulum
seen. Perhaps the Ca ions and the pectase
thrust through from the interior of the cell
meet at its frontier the pectin which under
enzyme action yields pectic acid in the pres-
ence of the Ca ions. The product of such an
occurrence would be seen in the cementing layer
formed on the outside of each of the now
neighboring cells.
In conclusion, I should like to refer briefly
to some of the more practical results that
seem to flow from the considerations that have
been here set forth.
It appears that a certain quantity of Ca ions
must be present in the medium for the main-
tenance of the chemical and functional integ-
rity of the cell wall, as well as the chemical
and functional integrity of the deeper lying
living parts of the cells of absorbing roots of
higher green plants. When this is so main-
tained, absorption takes place in the manner
we are accustomed to call normal. When this
necessary minimal supply of Ca ions in the
medium is lacking, be it in soil solution, water
culture, or sand culture, the function of
absorption is upset and a more or less marked

[Vou. LV. No. 1410.
leaching of ions from the plant follows. In
the absence of this necessary minimum of Ca
ions, the soil solution or culture solution may
be rich in all other required ions, but these
are useless to the plant. They are unabsorb-
able. This brings us face to face with a con-
dition of affairs in plant nutrition that has
not been recognized and therefore has not been
characterized. We may fairly say that Ca
ions make physiologically available other
equally indispensable nutrient ions. The prac-
tical consequences that follow from this way
of looking at the fertilizer problem have not
thus far been realized. We learn why from
earliest times civilizations have grown up on
soils rich in limestone débris. We learn why
agriculture has readily succeeded in some
regions, not in others. We understand why,
by the~use of lime, lands have been rendered
capable of supporting largely increased popu-
lations. We are now able to correlate these
broad facts with those of cell physiology and
to suggest perhaps not the calcium function
sought by Jost, but one way perhaps of many
in which higher green plants find caleium
necessary.

THE METHOD OF SCIENCE IN AGRI-
CULTURE?
To be practical has been the great goal of
agricultural investigation from the beginning.
It was entered upon with a practical purpose,
and in a large degree practical results early
came to the expectation of the farming people.
Here was a type of science which was not
working in the clouds for its own sake, but
down in the dirt where the problems of farm-
ing lay.
It is fortunate that this has been so—that
this close sympathy and this urge to meet the
needs of the art have been felt so keenly. It
has given life as well as purpose to our branch
of science, and the wide extent to which its

findings have been embraced and woven into the
warp and woof of intelligent practice has been
a constant source of stimulation. It makes
even more imperative the call for steady prog-
ress, not only in getting practical results for
immediate use, but in securing deeper insight
and larger intelligence about the common things
of agriculture.
The problems of agricultural science have be-
come increasingly difficult. As the simpler
things lying near the surface are gradually
solved the underlying problems are seen to be
more complex and difficult, taxing knowledge,
skill, and imagination to increasing extent. Al-
most have they come to call for that rare per-
spicacity of the colored preacher who claimed
to be able “to explain the unexplainable, to
make known the unknowable, and to unscrew
the inscrutable.”
At all events, there is no more exacting field
of experimental inquiry at the present time,
and success in it is largely a matter of methods.
It calls for a clear conception of the nature
of problems and means for deriving the needed
data for their solution. Steady advancement
in some of the oldest and most common lines
of agricultural inquiry rests more largely on
the development of methods than on additional
experiments or the accumulation of data on
the conventional basis. It is the largest prob-
lem in agricultural investigation at the pres-
ent time, and it is so important that in a large
degree it determines the progress of science.
Fundamentally the method of science is the
same, of course, in agriculture as in the sim-
ple sciences. It makes no difference whether
the subject is cornmeal or a chemical com-
pound, the response of the growing plant or
the law of falling bodies, the experimental
method and requirements for the same grade
of inquiry are the same. But in practice differ-
ent types of effort are represented which vary
with respect to their aim and the extent to
which they require application of the scientific
method. The difference is perhaps chiefly a
quantitative one, of degree rather than kind,
in conception of the end of inquiry rather
than in general essentials which must be met.
SCIENCE 7
In the simpler form of agricultural work,
consisting of observations, tests and trials, the
object may be a quite superficial one—the at-
tempt merely to get a bit of information but
one step removed from ordinary experience,
such as the profit from use of a fertilizer, the
larger crop from spraying, or the advantage
of fall plowing. The information may be quite
sufficient for the practical purposes of the time
and place, but it can not be said to be very
scientific, even if made with every care, for
the work involves no study of exact relation-
ships or tracing of the effect of conditions. In
other cases observations, tests and trials may
have a deeper purpose and form a step in in-
vestigation. Similarly, experiments may be
purely comparative, as showing the relative
value of different fertilizers, or feeding stuffs
or methods of tillage, without touching any
basie fact; or they may be the means of secur-
ing scientific facts in a piece of fundamental
research.
In the early stages of agricultural experi-
mentation, before the problems had been or-
ganized to show their nature and content, the
work was naturally elementary, based largely
on observations, comparative trials, and simple
experiments which did not attempt to determine
the underlying conditions or establish definite
relationships. These types of work have given
results which although largely empirical have
been extremely useful. They have supplied a
great fund of information on which to develop
practical systems and to base further experi-
mental inquiry. Although sufficient for one
stage, they may be a poor means of progress
in another. Hence they need to be replaced
by more rigorous methods and by investigation
which goes to the heart of the problems.
It has been a somewhat prevalent mistake
to assume that a complex agricultural problem
could be solved in its practical aspects without
a study of the principles and factors underlying
it. This has led to the attempt to secure quick
results by short cuts, and has bred overcon-
fidence in the competence of simple comparative
experiments. Reliance upon such time-honored
procedure in certain classes of work has re-
8 SCIENCE
sulted in the effort to refine them without go-
ing outside of them or bringing to their sup-
port more abstract types of inquiry which the
changing status of the problems made neces-
sary.
This is not to overlook or to minimize in
the least the increasing extent to which agri-
cultural research has advanced into new fields
or stages of inquiry, has developed improved
methods and means of progress, and has been
rewarded with results comparable with those
in any line of investigation. Such effort has
well illustrated the truth that in this branch
of research as in other walks of life “we build
the ladder by which we rise’’; and it argues for
a type of experimental work which is critical
of its methods and conclusions, seeking means
for strengthening them and avoiding error or
uncertainty. But certain types of work have
not been marked by such growth of vision and
method, with the result that they have become
doubtful means of scientific progress at the
present time. They continue to perpetuate
their possible errors or inherent limitations
after these have been disclosed. They are not
fulfilling the expectations originally placed
upon them; and while they have been useful
up to a certain point, they are accumulating
data after they have ceased to shed new light.
The aim of science is simplicity, the dissolu-
tion of complexities, and development of sim-
ple facts and statements easily comprehended.
Its method begins with a simplifying process,
the analysis of problems to get at their real
nature and content, the resolution of complex
questions into parts which are sufficiently sim-
ple and self-contained to be capable of study.
Often this can be only partially done at the
outset, but as the investigation proceeds and
the real nature of the problem is disclosed, the
segregating process becomes easier.
In agricultural investigation this is difficult
because of the many factors embraced, and in
the more common types of work with plants and
animals it has been followed to only a limited
extent. More often the problem has been an
involved and complex one from the start, em-
bracing a wide range of phenomena, and in-
[VoL. LV. No. 1410.
stead of being simplified and reduced to smaller
definite units as the work progressed, it has
gathered bulk as it went, like a snow ball, until
it has become such a complicated aggregation
as to be well-nigh unworkable. Toc large for
any intimate study, the mechanies and routine
of it have oceupied the full time, and it has
often degenerated into the broad accumulation
of data.
In constructive research data are secured
for use, not for themselves. They are designed
for a definite purpose—to solve a concrete prob-
lem, to prove or disprove a conception or an
idea, to disclose scientifie facts. The undirected
collection of facts, whether they be observa-
tions, results of experiments, or what not, leads
to complexity, to an aggregation of data which
must first be classified before being used in
molding a scientifie explanation or a principle,
or developing even practical information. Un-
less there is a clear objective and an idea to
guide in the acquiring of data, it may be a
waste of time, an aimless, hopeless, dead effort.
Its results may be chaotic, impossible of de-
veloping a leading principle or an illuminating
fact.
There is still a quite prevalent idea that the
ends of research may be satisfied by the aceu-
mulation of data. It is a common expression
in connection with the status of long-continued
experiments that data are being accumulated.
This is especially apt to be the case where
such complex conditions and factors are in-
volved that the results from year to year are
confusing, and it is assumed that these uncon-
trolled variables may be eliminated by long
repetition. In such eases there is apt to be
lack of a eritical attitude toward both the
method and the data themselves, and hence the
test of adequacy or competence is not applied.
Data add to the accumulated fund of informa-
tion when they are accurate, systematic and
orderly, and so eapable of enabling deductions
or fitting into other supplies which may he
so used. Unless they respond to such a test
it may well be questioned whether their aceumu-
lation is profitable at this stage, when there
is already such a large background.
January 6, 1922]
Simplification and definiteness of purpose
give direction to the making of records and
the gathering of data. All experimental in-
quiry turns upon securing proof which is both
accurate and adequate to the purpose. The
method of science is the process of securing
accuracy and precision in purposeful observa-
tion, and the interpretation of the product.
As has been said, it is “only a perfected apphi-
cation of our human resources of observation
and reflection.”
The method is not a fixed thing but is con-
tinually changing as progress makes possible.
Science strives constantly after new ways of
acquiring and proving facts which would other-
wise not be known or but imperfectly so, and
at the same time eliminating the personal
factor. Apparatus and appliances are de-
signed primarily to make possible the taking
of observations which would otherwise not be
feasible, or with equal accuracy. They there-
fore enlarge the field of observation and in-
crease precision.
This applies of course to facilities and
methods for agricultural inquiry such as field
plats and cylinders, feeding appliances, special
apparatus and other means for securing experi-
mental data; and there is the same need of
critical examination of these from time to time
that there is of other facilities, to determine
whether they are supplying proof which is
accurate and sufficient, or to assess correctly
what can and what can not be shown by such
methods.
The question is forcing itself upon the minds
of many as to the adequacy of certain types of
field experiments, as ordinarily conducted, to
answer fundamental questions in plant nutri-
tion and soil management. Large reliance has
been placed on such experiments in the past,
and data have been accumulated from them
over long periods. The oldest series of fer-
tilizer and rotation plats in this country runs
baek over forty years; several others have been
under way from twenty-five to thirty-five
years. One station has some two thousand
plats.
These experiments have brought highly
important practical results, and have marked
SCIENCE 9
a definite step in agricultural inquiry. They
have furnished a rich background of material
and suggestion for more definitely directed
studies. The question is whether they have
reached their maximum and how far they are
to be depended upon in making further ad-
vances.
It is now realized that many of these experi-
ments contain inherent difficulties dating back
to their beginning, which introduce a strong
element of doubt in interpreting results. For
one thing, most of the published reports fail
to deseribe the soil except in the most general
way, and lack information as to the condition
and previous treatment of the field, indications
of irregularity, ete. Again, the number of
check plats is usually too small, and the same
is true of the amount of replication of treat-
ment. This may account for the different
interpretations made by different persons from
the same series of experiments. In few eases
has the necessary number of checks and dupli-
cates been worked out mathematically for such
experiments, and where there is considerable
variation in different parts of a field, averages
may furnish a doubtful basis for measuring the
effect of treatments.
The number of questions “put to the soil
and the plant” in a given plat experiment has
usually been far too large. For example, the
customary rotation-fertilizer experiment has
often covered practically the whole range of
soil fertility and plant nutrition. This wide
range has limited the amount of replication
practicable, and it has failed to reflect the
discrimination in gathering data and_ the
simplification of the problem dictated by the
method of science.
Such experiments have relied quite largely
on what the field results themselves were inter-
preted to show, primarily the crop returns.
True, most of the later experiments have em-
bodied plans for chemical, bacteriological, and
other laboratory studies, but only to a limited
extent have these been developed with the
progress of the work so as to shed new light.
The chemical studies have often become of a
routine nature—analyses of the crops and of
the soils at stated intervals, and the bacteri-
ological studies by the technique developed
10 SCIENCE
have largely failed to meet expectations in
establishing correlations between soil treatment
and bacterial flora. Such bacteriological ob-
servations have now almost ceased in connec-
tion with long continued field experiments.
Reduced to such a simple collection of experi-
mental data, the conduct of these extensive field
experiments has often become largely a matter
of routine. The niceties of plat work are
observed, but the element of actual inquiry is
deferred until many years have supplied their
data. When that time is reached the publica-
tion is more often a summary of field and
and laboratory records than a critical analysis
of the data and their actual meaning. At best
the product is quite apt to consist of empirical
observations rather than definite contributions
to fundamental principles. We have not yet
learned how to interpret, except superficially,
the answer which the soil and the plant give as
to just what has happened or what the ap-
parent effects are due to. We have not yet
learned how to examine a plot of soil so as to
determine the changes occurring from time to
time or brought about by a long continued
system of treatment, or how to connect these
changes with the response of the crop in a
given season or period. Indeed, relatively
little study is now given in such experiments
to the soil itself, and only to a limited extent
are underlying questions suggested by such
experiments being given intensive study.
In a word, the indications are that in the
majority of cases the use is not being made of
such long-time field experiments that ought to
be made at this stage. They are rarely being
simplified as time goes on, with a narrowing
down to specific problems for intensive
research, and they are not being increasingly
supplemented by definitely directed laboratory
study. They ought themselves to be progres-
sive both in method and outlook. They ought
to be used as the source of problems and mate-
rial with which to make further and more pro-
found inquiries.
We can hardly fail to recognize the changed
status at the present time, both as to practical
requirements and the stage which has been
reached in research and its problems. What is
especially needed at this stage is the study of
factors and their relationships rather than
[Vou. LV. No. 1410.
gross comparisons of one complex of conditions
with other complexes. This will eall for the
kind of team work which has been applied to
the Rothamsted experiments,—the association
of the chemist and the bacteriologist with the
agronomist and soil expert, and the guidance
of the statistician in both planning and inter-
pretation.
In many of the feeding experiments, also,
the unchecked sources of possible error are too
great for safety. The small number of animals
in the lots gives large chances for the influence
of individual variation. The conditions and
frequency of weighing may also give mislead-
ing indications. Some of the results of such
experiments can be measured quite accurately,
while others ean only be described. Some are
not strictly experimental because they embody
so many factors not under experimental control
and whose probable variation can not be esti-
mated. This is true, as Dr. H. H. Mitchell
has recently shown, of the cost or financial
returns in feeding. Such results lack per-
manent value, and are likely to be given a
prominence and an application which they are
not entitled to.
Experiments of this practical type have been
useful in the past and there will be need for
them in future. It is important that they
occupy their proper place; but in the scheme
for investigation they should not take the place
of nutrition studies based on more permanent
factors than prices and food combinations, or
reliance rest too largely on them at this stage.
Many important advancements have been
made in animal nutrition which will find appli-
cation in feeding practice and in showing the
reason back of it. These disclose more clearly
the functions to be discharged by food, the
inherent qualities which account for the ob-
served value or special properties of feeds, and
the means of measuring the response of the
animal with a high degree of accuracy. Such
fundamental! investigations ought assuredly to
be encouraged, not to the exclusion of but along
with the type of feeding experiments which
seek a more immediately practical end.
There is still need to cultivate intelligent
public appreciation of research conducted in
accordance with the spirit and the method of
JANUARY 6, 1922]
science. It has been far easier to get funds for
types of work which promise early contribu-
tions to practice than those which dig deep and
lay solid foundations to make the whole super-
structure sure. The dependence of the former
upon the latter needs to be recognized.
The magnificent work of Armsby and _ his
associates has been the admiration of the scien-
tifie world, but in spite of its ultimate practical
value, and especially in furthering investiga-
tion, it had not within itself the elements of
publicity, and was only vaguely understood.
It never had an assured permanent income,
and in that sense was obliged to live from hand
to mouth. The loss this entailed is realized
too late; and now the future of the work he
so admirably started is under discussion. It
would be a calamity if it were allowed to fall
to the ground.
The large amount of attention now being
given to fundamental and searching inquiry
on the soil, the conditions of plant growth, and
related subjects, should not fail of mention in
this connection, for it illustrates the develop-
ment of insight into these problems. At no
period has there been anything comparable to
it. The results which are following from these
iitensive studies amply justify the expectations
of them as constructive means of progress.
With all the facts clearly in mind, it is very
important to take an account of stock in the
more conventional lines of experiment; to
study seriously the long list of the better
experiments in order to determine what they
have actually shown, what they are com-
petent to show, and the lessons they teach
in methods. By all means, let us garner in all
the teachings of these field and other common
types of experiment; let us profit by both the
good and the bad experience, but let not the
negative results be overlooked in searching for
the more positive ones. Such experiments rep-
resent large annual expenditures, and they
occupy the time of a large body of workers.
They express a confidence on which men are
staking their efforts and their prospects. It is
important to know the place which such experi-
ments should occupy in future study and the
manner in which they need to be supplemented.
SCIENCE 11
This may be one of the fundamental lessons
to be drawn from them, and may indicate that
their most useful field is in supplementing
laboratory studies, rather than the reverse as
at present.
In a public supported enterprise like agri-
cultural investigation there must necessarily
be a happy combination of effort representing
different grades of intensity. Some problems
or stages of them call more urgently for the
full measure of the method of science than
others, and it will be for the investigator to
govern himself accordingly. But he can not
fail to exercise a critical attitude toward all
his work and his methods, or to exemplify in
them the element of real progress.

THE CONCILIUM BIBLIOGRAPHICUM
In the issue of Science of December 2, I
called attention to the critical situation in which
I found the Concilium Bibliographicum this
summer, when I made a special trip to Zurich
to investigate this situation for the National
Research Council and the Rockefeller Founda-
tion.
On the occasion of this visit I proposed,
after conferences with Mrs. Field (widow of
the late Dr. H. H. Field), her business ad-
visers, the chief of the technical staff of the
Concilium, and official representatives of the
Swiss Natural Science Association, which be-
comes under Dr. Field’s will the legatee, under
certain conditions, of Dr. Field’s financial in-
terests in the Concilium, a plan for an imme-
diate temporary reorganization of the Con-
cilium to last until January 1, 1922, and a
further plan for a provisional permanent re-
organization to go into effect as from that date.
The plan for temporary reorganization was
put into effect immediately with Professor J.
Strohl, of the Zoological Institute of the Uni-
versity of Zurich, as acting director, without
salary. The proposed provisional permanent
reorganization—by “provisional permanent” I
mean a well considered and fully supported
organization to run on until international mat-
12 SCIENCE
ters may indicate a desirable change—required,
for putting into effect, the approval and defi-
nite action of the Field estate, the Swiss Nat-
ural Science Association, the National Re-
search Council, and the Rockefeller Founda-
tion. I obtained the formal agreement of the
Field estate and Swiss Association before
leaving Zurich and now the Research Council
and the Rockefeller Foundation have signi-
fied formal approval and taken the necessary
definite action.
This arrangement, which would require too
much space to set out in detail here, provides
for the control of the Coneilium, until some
later arrangement for control by a satisfae-
tory international board can be made, by a
special Commission set up by the Swiss Nat-
ural Science Association on which there shall
be an official representative of the National
Research Council whose acquiescence must be
obtained for any major activity or expenditure
of funds proposed by the commission. In
addition, the National Research Council sets
up a special committee on Concilium matters
to advise and instruct the Council representa-
tive on the Swiss Commission. This commit-
tee of the Research Council is composed of
Drs. R. M. Yerkes and L. R. Jones, and my-
self as chairman. I am also appointed as the
Council’s representative on the Swiss Commis-
sion.
To clear up the current obligations of the
Coneilium and help maintain it during the next
five years the Rockefeller Foundation has ap-
priated and pledged to the National Research
Council the following sums: Appropriated:
to meet outstanding obligations, $15,000, and
for maintenance during 1922, $20,000; pledged:
for maintenance during 1923, $20,000; during
1924, $15,000; 1925, $10,000; 1926, $5,000,
after which the Foundation assumes no fur-
ther financial obligation for the Concilium. This
means that the Concilium must arrive at a self-
sustaining condition by January 1, 1927, or
have found by then other philanthropic as-
sistance.
It is proposed that a staff composed of a
director, a competent secretary-bookkeeper,
[Von. LV. No. 1410.
three trained technical assistants, three un-
trained assistants, and the needed stenograph-
ers and messengers, be arranged for at once.
To maintain this staff and provide the neces-
sary office expenses (postage, telegraph, tele-
phone, fuel, lighting, ete.) the Concilium has
not only the Rockefeller Foundation subven-
tion but an annual subsidy of 5,000 franes
(Swiss) a year from the Swiss Government
and one of 1,000 franes (Swiss) from the
Canton of Zurich. It has also whatever income
ean be derived from sale of its bibliographic
cards and books. It has a building of its own,
well suited and fairly well equipped for its
work.
Thus the Concilium has, thanks to the gen-
erous action of the Rockefeller Foundation, a
new lease of life and Dr. Field’s noble and
self-sacrificing work and his plans for imereas-
ing the Concilium’s usefulness are not to go
unregarded. Plans for extending the biblio-
graphic work to other fields not now covered
by it, and for a possible development of an
abstracting system in addition to the present
subject, title and author references, are under
consideration. In this connection the manag-
ing board of the Concilium will need and will
welcome all the advice that can be given it.
There should be, also, a greatly inereased
list of subscribers to the cards and books issued
by the Concilium. The National Research
Council will undertake a campaign to add to
the list of American subscribers, and the Di-
rector (in Zurich) will institute a similar cam-
paign in Europe. So I shall have occasion to
ask the editor of Science for space in the near
future for still another note about the Con-
cilium.

HENRY TURNER EDDY
Tue death of Henry Turner Eddy occurred
at his home in Minneapolis on December 11,
1921, due to an acute attack of pneumonia,
after only a few days’ illness.
Dr. Eddy was born at Stoughton, Mass., on
June 9, 1844. He was the son of Henry Eddy,
JANUARY 6, 1922]
Yale ’32, Congregational minister, and Sarah
Hayward (Torrey) Eddy, a graduate and
teacher of mathematics at Mt. Holyoke Sem-
inary.
Dr. Eddy graduated from Yale A.B. 67,
Ph.B. ’68, A.M. ’70, Hon. Se.D. 1912; Cornell,
C.E. °70, Ph.D. ’72; and Centre College (Ky.)
LL.D. He also studied at the University of
Berlin and at the Sorbonne, Paris. He was
instructor in Latin and mathematies at the
University of Tennessee, 1868-9; assistant pro-
fessor of mathematics and civil engineering,
Cornell, 1869-73; adjutor professor mathe-
matics, Princeton, 1873-4; professor of mathe-
matics and astronomy and civil engineering,
1874-90, and dean of the academic faculty,
1874-7, at the University of Cincinnati, and
was its president-elect in 1890. The following
year he went to Rose Polytechnic Institute,
Terre Haute, Indiana, as its president and
remained there until 1894, when he resigned
and went to the University of Minnesota as
professor of engineering and mechanics, in the
College of Engineering. In 1906 he
elected dean of the Graduate School, which
position he held until his retirement from
university work in 1912 as professor and dean
emeritus.
After his retirement from teaching at 68
years of age, Dr. Eddy formed an association
with Mr. C. A. P. Turner, consulting engineer,
of Minneapolis, and spent several happy years
in mathematical researches concerning the
properties and stresses in reinforced concrete
floor slabs, the results of which he published in
collaboration with Mr. Turner. Dr. Eddy was
one of the first to take up the subject of
graphical statics and in 1878 he published his
well-known “Researches in Graphical Staties” ;
this was followed in 1879 by a treatise on
“Thermodynamics”; previously to this he had
published a mathematical text on “Analytical
Geometry.”
Dr. Eddy was a member of numerous scien-
tific societies of varied interest, including the
American Association for the Advancement of
Science, of which he was one of the vice-
presidents in 1884; the American Philosophical
Society, the American Mathematical Society,
the American Physical Society, and the Soci-
Was
SCIENCE 13
ety for the Promotion of Engineering Educa-
tion, of which he was an honored past presi-
dent. He was a man of versatile attainments,
as shown by his many valuable contributions
to the various societies to which he belonged.
Dr. Eddy was a man of quiet, scholarly
tastes, genial in his intercourse and always an
inspiration to his associates. He was married
in 1870 to Sebella Elizabeth Taylor, of New
Haven, Conn., who died on September 5, 1921,
only three months prior to the death of her
husband. The surviving children are: Horace
T. Eddy, Omaha; Mrs. Charles F. Keyes,
Minneapolis; Mrs. Clive Hastings, Atchison,
Kan.; Mrs. Charles H. Patek, Minneapolis,
and Mrs. J. B. Frear, Buffalo, N. Y.
The faculty of the Graduate School of the
University of Minnesota has placed on its
records the following tribute:
Henry Turner Eddy, Ph.D., LL.D., died on
December 11, 1921, at the age of 77 years. In
his death the faculty of the University has lost
one of its most eminent and honored members.
As professor of mathematics and mechanics
from 1894 to 1905, as the first dean of the Gradu-
ate School from 1906 to 1912, and as professor
emeritus since 1912, Dr. Eddy was a distinguished
associate whom the faculty was proud to own as
a colleague. His ability as a mathematician won
him an international reputation and his high
general scholarship and Christian character en-
deared him to all with whom he came in contact.
He was an educator of the highest type, an
inspiration to his students and intimate associates,
and a wise, sympathetic counsellor in the faculty
conferences.
This faculty would express its heartfelt sym-
pathy with the family, in the faith that God has
given the departed a rich reward; and the assur-
ance that it cherishes the memory of a noble life
that has left a precious and imperishable
heritage. Ay aie
SCIENTIFIC EVENTS
THE STERLING HALL OF MEDICINE OF
YALE UNIVERSITY
Tur Yale Corporation and the Sterling
Trustees will appropriate from the Sterling
funds the amount of $1,320,000 for the erec-
tion of a new and modern building to be known
as the Sterling Hall of Medicine. With this
14 SCIENCE
purpose in view the university has recently
acquired most of the city block bounded by
Cedar, Broad, Palmer and Rose streets where
the dispensary now stands, opposite the New
Haven Hospital.
The Sterling Hall of Medicine will have a
central entrance and building at the corner of
Broad and Cedar streets containing a library
of approximately 12,000 volumes, an amphi-
theater with a seating capacity of about 250,
the administrative offices of the dean and
registrar, a room for faculty use, students’
common room, and on the third and fourth
floors single rooms and suites for unmarried
instructors in the pre-clinical subjects. Ex-
tending along Broad street a wing will provide
space and laboratories on the first and second
floors for the department of physical physi-
ology, with like provision on the third and
fourth floors for the department of pharma-
cology and toxicology. A similar wing facing
the Brady Laboratory and the administration
building of the New Haven Hospital on Cedar
street will provide on the first and second
floors space for the department of chemical
physiology, the two upper floors being given
over to laboratory space for anatomy. Beyond
the central structure will be an animal house
where various types of domestic animals will be
kept for experimentation and _ observation,
these being available for all departments of
the university located in the vicinity of the hos-
pital. The power house, designed on the unit
basis with stack and bunkers of sufficient
capacity for future requirements of the hos-
pital and the school, will be situated at the
corner opposite to the central building.
Day & Klauder, of Philadelphia, are the
architects of the Sterling Hall of Medicine.
One of the features of this building will be the
provision for future expansion as the needs
of the School of Medicine require and _ its
finances permit. This means the ultimate
completion of the quadrangle.
One of the features of the expansion of the
Yale School of Medicine has been its closer
affiliation with the New Haven Hospital and
the Dispensary. In addition the finances of
the hospital have been placed on a stronger
footing and the physical rehabilitation has been
begun.
[ Vou. LV. No. 1410.
Placing the faculty of the Medical School on
a university basis of full time organization in
the clinical service has been an important step
in the consolidation of the work of the Med-
ical School and the New Haven Hospital. With
the beginning of the fall term of the present
year all four of the clinical departments of
the School of Medicine have been placed on
such a basis.
THE CROP PROTECTION INSTITUTE
THE first annual meeting of the Crop Protec-
tion Institute will be held at Rochester, N. Y.,
in connection with the New York Horticultural
Society’s meeting. A dinner will be provided
on January 12 at the Rochester Chamber of
Commeree.
Among those taking part on the program
will be Professor W. C. O’Kane of the New
Hampshire Agricultural Experiment Station,
and chairman of the board of governors of the
Crop Protection Institute, who will speak on
the ideals of the institute; Dr. L. R. Jones,
chairman of the Division of Biology and Agri-
culture of the National Research Council,
whose theme will be the ‘Relation of Environ-
ment to Disease and Disease Resistance of
Plants”; Dr. R. W. Thatcher, director of the
New York Agricultural Experiment Station,
who will speak informally on the “Need for
Investigations in the Chemistry of Insecticides
and Fungicides.” From the standpoint of
industry, Mr. G. R. Cushman, of the General
Chemical Company, will speak briefly. Pro-
fessor P. J. Parrott, of the New York
Agricultural Experiment Station, will also
probably speak on ‘Paradichlorobenzene.”
The Crop Protection Institute, which has a
membership of about three hundred and fifty
prominent entomologists, plant patholo-
gists, agricultural chemists and manufacturers
of insecticides and fungicides and others inter-
ested in the protection of all kinds of crops,
was organized only a year ago, under the
auspices of the National Research Council of
Washington, D. C. The purpose of the insti-
tute is not to duplicate the work of individuals
or other organizations, but to bring about
closer cooperation of effort, to strengthen the
weak places and develop needed investigations
that are not being pursued by other agencies.

Those interested, though not members, are
invited to attend.
PUBLIC HEALTH WORK IN THE PHILIP-
PINES
The Rockefeller Foundation announces that
the International Health Board has accepted
an invitation to cooperate in carrying out the
general scheme of reorganization of the public
health activities of the Philippine Islands,
which was recently made publie by the presi-
dent of the Senate, Manuel Queson.
The participation of the board will consist
in lending the services of certain members of
its staff for a limited period and providing
specialists as consultants and assists to Philip-
pine government officials in various lines of
public-health work. The broad program which
the government has adopted for improving
health conditions includes the ultimate con-
solidation of all health functions in a single
department of health to correspond with the
ministry of health in other countries.
Among the persons whose services will be
furnished by the Rockefeller Foundation is an
assistant to the dean of the College of Medi-
cine and Surgery of the University of the
Philippines, who will assist in developing the
medical school and will give particular atten-
tion to the problem of providing post-graduate
instruction in public health, so that the health
workers so urgently needed in the Philippine
Islands may be trained locally.
Fellowships for advanced study in the
United States will be offered by the board to
exceptionally promising and _ well-qualified
young Filipinos, to fit them for the more
important administrative and technical posi-
tions in the public-health service and for posi-
tions as instructors in the College of Medicine
and Surgery and as teachers of nursing.
Existing facilities for the training of nurses
are said to be inadequate to meet the demand
for hospital and private service. The nursing
situation will therefore be studied and special
attention given to training women in public-
health nursing.
An assistant will be provided for the
director of the Bureau of Science, who will be
expected to advise in the further development
of that bureau. The Biological Laboratory,
SCIENCE 15
which is one department of the Bureau of
Science, is to be expanded in order to serve
as the central public-health laboratory of the
Philippines, with local laboratories in the
provinces.
Dr. Victor G. Heiser, director for the East
of the International Health Board, and for-
merly director of health for the Philippine
Islands, who is now in New York, will go to
Manila in February to assist in carrying out
the program.

by Dr. R. B. Sosman, corresponding secretary,
was compiled at the request of Dr. George F.
SCIENCE 17
Bowerman, librarian of the Publie Library of
the District of Columbia. The standard set up
for the books is that they must be both read-
able and scientifically accurate. The subjects
covered are anthropology and _ physiology,
heredity, botany, animals, birds and_ insects,
geology, meteorology, minerals, astronomy,
chemistry, physics, mathematies and history of
science.
The faculty of Mercer University on Decem-
ber 14, 1921, passed the following resolutions:
Resolved, That the Faculty of Mercer Univer-
sity favor the plan of placing the scientific
bureaus of the United States government under
the jurisdiction of a board of governors, with
the view of unifying all governmental science and
developing it to the highest possible efficiency,
by affording scientific workers permanent tenure
of office, greater freedom in investigation, non-
interference through politics, and adequate
salaries.
Resolved, That a majority, at least, of the said
board of governors be appointed by the American
Association for the Advancement of Science, in
order that the most able executives in the various
fields of science may be appointed to such an
important governing board, and that its per-
sonnel be free from political influences.
We learn from the Journal of the American
Medical Association that Senator Wadsworth,
of New York, has presented a bill in congress
providing for an appropriation of $143,032 to
meet the increased cost of land needed adjoin-
ing the Walter Reed General Hospital in
Washington. On this real estate it is proposed
to erect buildings for the medical museum and
library and the Army medical school. At the
request of Surgeon General Ireland, Congress
appropriated two years ago the sum _ of
$350,000 for the purchase of this land, but
since the negotiations for the taking over of
the property have been under way it has been
discovered that it could not be bought at this
figure. A request for more money from Con-
gress, therefore, was necessary. Immediate
purchase is urged both by Senator Wads-
worth, chairman of the Senate committee on
military affairs, and Surgeon General Ireland,
because it is believed that the land will
increase in price in the future and the govern-
ment should act now as a matter of economy.
18 SCIENCE
The Army medical school is to be the first
building erected at a cost of $500,000.
THE returns of the British registrar-general
for the quarter ending September, 1921, have
been issued. They show that in England and
Wales there were 214,850 births, which were
15,017 fewer than in the third quarter of 1920.
The rate was 22.5 a year for each thousand of
population. The deaths numbered 99,134, and
were 9,937 fewer than in the preceding quarter,
but 5,444 more than in the third quarter of
1920. The rate was 10.4 per thousand. The
infant mortality was 83 per thousand births,
being 15 below the average of the ten preceding
third quarters.
UNIVERSITY AND EDUCATIONAL
NOTES
Aw endowment of $110,000 for the depart-
ment of art as applied to medicine has been
given to the Johns Hopkins Medical School.
The gift, by an anonymous donor, was trans-
mitted to the trustees through Dr. Thomas S.
Cullen. This department has been established
since 1911, with Max Brodel at its head, the
same anonymous donor having provided funds
for its maintenance.
Work has begun at Pomona College, Clare-
mont, California, on a new chemistry building
to cost nearly $250,000. The building will be
of reinforced concrete with tile roof and mas-
sive tower to conform with the accepted archi-
tecture of the college campus. It will provide
facilities in undergraduate and research work
for 600 students.

DISCUSSION AND CORRESPOND-
ENCE
PUBLIC HEALTH AND MEDICAL PRACTICE
THE article “Education in Relation to Public
Health and Medical Practice, by Professor
S. J. Holmes, which appears in the issue of
Science of November 25, 1921, is a highly
interesting presentation of a subject which will
merit discussion. Its author, however, falls
into the common error of those eriticizing an-
other profession than their own, of somewhat
overstating the case and taking a too pessimis-
tie view of a situation which is constantly being
bettered, as, for instance, when he states that
“a large part of the time of well-trained med-
ical men is simply wasted in a kind of desul-
tory practice from which their patients secure
no permanent benefit,’ and that “humanity
comes very far short of getting out of the
medical profession the aid which it is capable
of furnishing.” As a matter of fact, there
are 106,000,000 persons in this country the
vast majority of whom are perfectly well cared
for medically. The death rate in our larger
cities is constantly fallmg and there are
increasing numbers of organizations devoted
exclusively to the study and promulgation of
public sanitation which are maintained by
physicians who furnish gratuitous time and
energy without stint. The laboratory tests
which the author enumerates are, for the most
part, now taught to every third year medical
student and the more elaborate tests of this
order are not required by more than four or
five per cent. of all patients.
The author further comments upon the
ignorance of sanitation among our immigrants
(which, of course, is deplorable) and writes
that the “uninstructed foreigner” “fails to get
competent aid when he is ill.”
JANUARY 6, 1922]
New York City has admittedly the largest
and most varied immigrant population of the
country. It has, however, many competent
foreign born physicians who care for their
own kind, besides many hospitals devoted to
the care of special foreign groups, like the
Italian, French and Lenox Hill (formerly the
German Hospitals, besides several others de-
voted to Yiddish patients. The Health Board
of the city is most active and efficient, together
with many other agencies, both public and
private, in raising the health standards among
the foreign born, and special health lectures
are given in different languages in the public
schools. The infant mortality of the entire
city has never been so low as in the past few
years and is a source of amazement to distin-
guished foreign members of the medical pro-
fession who come here. The comments of the
author upon the fraudulent medical cults with
which the country abounds are well made and
nowhere to be better ilustrated than in his own
quack-beridden state of California, but it is
unfair to shift any of the burden of this upon
an assumed negligence of the medical profes-
sion, which wages constant warfare against it
in its county, state, and national associations,
only to be defeated time and again by lay
legislators. There are too many other opera-
tive factors, notably the sensational press, the
general restlessness of the times, and indeed the
multiplicity of experimental medical tests them-
selves, which lead patients to compare experi-
ences with one another and seek all manner of
examinations whether they need them or not,
in order to get their money’s worth out of what
the author characterizes as “our commercialized
system of private practice’—which remark
leads one to wonder whether he knows the
average income of the legitimate medical prac-
titioner.

NOTE ON INHERITANCE IN SWINE
Tue Berkshire pig is distinguished by the
following characters: (1) erect ears, (2) uni-
form black coat with the exception of “six
white points” which oceur on the head, on each
SCIENCE 19
foot and on the tail, (3) a short “dished” nose,
and (4) a somewhat short and broad body.
The Large Black pig is distinguished by (1)
“flop” ears, (2) uniform black coat without
any white, (3) nose not “dished” and of
moderate length, and (4) a long body, some-
what narrower than that of the Berkshire. On
a farm near Oxford, pure-bred Large Black
boars have for some years been crossed with
pure-bred Berkshire sows. About a dozen lit-
ters have come under the observation of the
author of this note and the F! generation has
invariably shown (1) erect ears, (2) uniform
black coat without any white, and (3 & 4) in-
termediate features as regards nose and shape
of body. Latterly, the reciprocal cross has
been made (Berkshire boar and Large Black
sow) and the ‘F! generation shows (1) erect
ears and (3 & 4) intermediate characters. But
as regards (2) there has appeared a gradation
from pure black to spotted pigs in which the
whole coat is fairly evenly divided into black
and white patches. At present the numbers are
small, but it would appear that the gradation
is not uniform between the pure black and the
spotted condition. There appear to be three
classes—pure black, black with the six Berk-
shire points and spotted. Further it is notice-
able that the true spotted pigs have hitherto
all been boars, though pure black boars have
also appeared.
It may be suggested that erect ear is a
simple dominant. The coat color and other
features clearly require considerable analysis.
It may he that sex linkage is in some way
concerned in coloration.

Tue forerunner of the present work, under

SKY BRIGHTNESS AND DAYLIGHT ILLUMI-
NATION
What is the relation between sky brightness
and the electric light load carried by the central
lighting plant? How much sky-light will be cut
off by a row of buildings on the opposite side
of the street These questions and many others
may be solved by studies of the brightness of
the sky and daylight illumination such as have
been carried out by Dr. H. H. Kimball, of the
Weather Bureau at Washington. The prac-
tical utility of such investigations is attested
by the interest shown by illuminating engi-
neers, architects and electrical engineers. A
paper, recently appearing in the Monthly
Weather Review,! summarizes with considera-
ble detail a report submitted to the [luminat-
ing Engineering Society, of whose committee
on sky brightness Dr. Kimball is chairman.
The observational program which has been
followed in making the measurements has been
to make photometric readings with a Sharp-
Millar photometer at elevations of 2°, 15°, 50°,
45°, 60°, 75° and 90° above the horizon on ver-
tical circles at azimuth intervals of 45° begin-
ning with the sun’s vertical and proceeding
half-way around the horizon. Only half the
sky is measured because it is assumed that the

ness and daylight illumination

measurements.
JANUARY 6, 1922]
brightness distribution is symmetrical about a
vertical semicirele passing through the sun.
Such measurements were made on days that
were (1) perfectly clear, (2) overcast with
thin clouds or dense haze, (3) completely
overeast with clouds or dense fog, so that
neither sun nor blue sky could be seen, (4)
overeast with clouds from which rain or snow
was falling, and (5) partly overcast, in an
irregular manner.
On clear days it was found that the sky
brightness at Washington has somewhat the
following distribution: The brightest part of
the sky is, of course, that close about the sun.
The darkest part is that in the solar vertical
about 90° distant from the sun. In general,
the sky inereases in brightness toward the
horizon, although there is a “dark valley” ex-
tending from the dark point in the solar ver-
tical to a point about midway between the
sun and the horizon. This distribution agrees
closely with that observed by Dorno at Davos,
Switzerland, except that the Swiss sky is
brighter than that at Washington. This differ-
ence in brightness is probably the result of
secondary reflection of light from the Alpine
snows. In comparison with observations made
at Chicago University and on the roof of the
Federal Building in “Loop” district of Chi-
eago, it was found that the distribution there
is much the same, except that the horizon
opposite the sun is darker at Chicago than at
Washington. This is attributed to smoke,
from which the Washington atmosphere is par-
ticularly free.
The brightest type of sky measured at
Washington is that completely overcast with
thin clouds or dense haze. With clouds from
which rain is falling, the distribution is about
the same as with thin clouds, but its intensity
is only half as great.
Measurements of the illumination on _ hori-
zontal and vertical surfaces were made at
Washington and at the two Chicago stations
mentioned above. It was found with respect
to the variations with change of solar altitude
that the illumination on horizontal surfaces
inereased markedly with inerease of solar alti-
tude; but in the case of illumination on vertical
surfaces the difference between a surface facing
SCIENCE 21
the sun and one oppositely directed grows less
with increase of solar altitude. Moreover,
The daylight illumination on a vertical surface
facing opposite the sun, and with an unobstructed
exposure to the sky, in the Loop district of Chi-
cago under summer conditions as regards smoke,
averages only about two thirds as intense as
illumination on a similarly exposed surface at
Washington under similar sky conditions with
respect to clouds, except when the sun is more
than 40° above the horizon and the sky is clear.
The equation,
Tan @ = h/wx/1/7 + tana),
is given for computing the shading effect of
buildings on the opposite side of the street.
@ is the angular height of a building as seen
from the center of a window across the street,
the width of the street being w. The horizontal
angle between a normal to the window and a
line joining a point p on the building opposite
is #, and h is the height of the obstructing
building above the point p. The author gives
a table showing the relation between x and @
for various values of h/w. Attention is
directed to the fact that the horizon is the most
effective illuminating agent for vertical sur-
faces, hence buildings and other objects on the
horizon are the most serious obstacles in the
question of illuminating rooms through ver-
tically placed windows, especially with a clear
sky.
Two interesting examples of the relation
between electric light load and sky brightness
are given. At Washington, on July 15 and
29, 1921, there occurred thunderstorms about
2:30 p.m. and noon, respectively. On the
former occasion, the daylight intensity fell
rather quickly to about one foot-candle and the
sudden increase in eleetrie light load caused by
the nearly simultaneous turning on of thou-
sands of electric lights was sufficient to put
the power plant out of commission. The sta-
tistician for the company states that
During the day in the business section a sudden
increase in current consumption occurs when the
day light illumination intensity falls below 1,500
foot-candles. The lower the intensity, the higher
the current consumption, but fluctuations in
intensity above 1,800 foot-candles have only a
negligible effect.
22 SCIENCE
It appears that some arrangement whereby
power companies supplying large cities could
have recourse to observations of daylight
illumination, especially during the thunder-
storm season, would be of decided benefit to
them, for the falling off of this illumination
would afford an index as to the proper time to
prepare to supply additional current.
This sketch is sufficient to indicate the char-
acter of the important work being done by
Dr. Kimball and to suggest some of the indus-
trial benefits to be derived from the study of
daylight under various types of cloudy and
smoky sky.

ON STEREOTROPISM AS A CAUSE OF CELL
DEGENERATION AND DEATH, AND ON
MEANS TO PROLONG THE LIFE
OF CELLS
In former investigations we have shown ! 2
that amoeboeytes of Limulus have the tendency
to move and to spread out in contact with
solid bodies. We thus found another instance
of a reaction which is common to many kinds
of cells and which we observed and analyzed
in 1897 and subsequent years and which we
désignated as stereotropism of tissue cells 3.
We further found that the blood cells of
Limulus, as a result of this stereotropie re-
sponse and the concomitant spreading out of
their protoplasm along the surface of the
solid body, underwent degenerative changes;
they lost their granules, became hyaline and
gradually motionless and then died. There was
some indication that this spreading out of the
cells was accompanied by a taking up of fluid
from the surrounding medium and that this led
to processes of solution which initiated the re-
trogressive changes. !. 2» 4
In order to prolong the life of these cells it
was therefore necessary to retard this exaggera-

ted stereotropic response which led to a spread-
ing out of the cell in contact with the solid
body. We found previously that this can be
done not only by keeping the cells at a lower
temperature, which retards other activities as
well as the stereotropic reactions and is there-
fore not specific, but in a specific manner by
enabling the cells to rest on a surface previous-
ly covered with a thin film of paraffine or va-
seline. 4 Jn contact with such a surface the
spreading out of the cells is considerably re-
tarded and the life of the cells and the dura-
tion of their amoeboid movement is prolonged.
In carrying out these experiments, we make
use of the experimental cell fibrin (amoebocyte)
tissue, a small piece of which we place on the
prepared surface and surround with the de-
sired kind of fluid.
Last summer at the Woods Hole Marine Bio-
logical Laboratory we continued these experi-
ments with the cooperation of Mr. K. C.
Blanchard ® and found an additional method of
preventing the extension of the cells and thus to
prolong their life and activities. This can be
accomplished by making the medium into which
the cells enter from the piece of tissue very
slightly acid, an observation which agrees with
our previous finding according to which the
cells perish in a neutral solution of isotonic
sodium chloride, but are preserved in such solu-
tions after addition of a very small amount of
either acid of alkali.?
In our recent experiments we found that in
such slightly acid media the cells leave the
tissue in dense masses and continue to move
for a considerable period of time; they are
preserved, their spreading out is much retard-
ed and their motor activity in consequence
much prolonged. In alkali the cells are like-
wise preserved for some time, but they begin
to spread out and become dissolved much earlier
than in acid.
It is possible to grade the effect of acid upon
the cells. If the acid used is too strong and

consequently the consistency of the cell too
great, their motility is diminished. If it is used
in too weak a concentration, the spreading out
and solution processes are not sufficiently de-
layed. In an intermediate concentration of the
acid, the consistency is such that the migration
of the cells out of the piece is readily possible
and at the same time the cells are preserved
and the stereotropic reaction is retarded. But
ultimately the cells begin to spread out and now
retrogressive changes set in even in these favor-
able media. However, it may be possible to
keep the cells active for six days or longer
even at room temperature, at which under or-
dinary conditions the cells spread out and be-
come hyaline on the first or second day.
In this case we recognize thus as the prin-
cipal cause of cell death an extreme degree of
reactivity of the cells in contact with solid sur-
faces. There is good reason for assuming that
this reaction leads to an increased permeability
of the surface of the cell which reaches a de-
gree which is injurious and is thus respon-
sible for the subsequent degenerative processes.
Conditions which prevent this extreme stereo-
tropic reaction tend therefore to prolong the
life of the cells. Acid acts in this way ap-
parently by increasing the consistency of the
cells, at least of its outer layer.
As we have shown elsewhere‘ there exists a
striking analogy between the behavior of the
amoebocytes and ordinary tissue cells. Through
agglutination the amoebocytes produce sheets of
a tissue-like material. After an incision in such
a tissue cells migrate from the cut edge into
the defect, in a way similar to tissue cells ad-
joining a wound. In both eases two factors
determine the direction of migration: (a) The
stereotropic reaction, (b) a tendency towards
centrifugal movement.
During the process of movement the amoebo-
eytes spread out and thus produce structures
totally unlike the original amoebocytes, but
closely resembling various tissues. theory closely resembles mine.
Bradford’s assumes unnecessary facts to ex-
plain the phenomenon. Later, I expect to give
a more detailed account of this common phe-
nomenon.

THE IDENTITY OF CERTAIN YELLOW PIG-
MENTS IN PLANTS AND ANIMALS
Lirrie attention seems to be paid, from the
physiological standpoint, to the fact that the
yellow pigments in certain animal organs have
been shown to be chemically identical with the
yellow pigments common in plants.
Some cases of the identity of lipochromes
(yellow pigments of animals) with carotinoids
(carotin, xanthophyll, lyeopersicin, and fucox-
anthin of plants) have been known for several
years,! and the list has recently been greatly
extended. The lipochromes of the following
animal tissues are now known to be either
chemically identical or isomeric with caro-
tinoids—the ear lobes, beaks, shanks, body fat
and blood serum of fowls, and the yolks of
their eggs;2 and the fat of the body, blood

It seems probable that the same is true of the
nerve cells of some animals and of the blood
plasma and body fat of the human body.
These pigments aré not synthesized by the ani-
mals, but are merely taken up from their food.
It is well known that carotin (C,,H,,) is a
highly unsaturated hydrocarbon. It has been
shown® that part of the unsaturated linkage
of its molecule is of a type that can be easily
satisfied by direct addition of oxygen. Xantho-
phyll is carotin dioxide (C,,H,,0,). Lycoper-
sicin has the same empirical formula as caro-
tin. Fucoxanthin (C,,H,,O,) contains more
oxygen than the others. The first two of these
pigments are widely distributed in plants. Not
only do they always accompany chlorophyll,
but they are also found in flowers, fruits, seeds,
and subterranean organs, and also in fungi.®
The physiological significance of the earo-
tinoids has, of course, not been wholly neglected.
It is commonly pointed out? that the tendency
of carotin to unite with oxygen may be sig-
in connection with photosynthesis,
which is a reduction process. Steenbock® has
suggested that the fat-soluble vitamine is iden-
tical with some of the carotinoids, while Pal-
mer? has cited cases that seem to cast doubt
on this view. Years ago Schunck!? suggested
the question as to whether xanthophyll, being
present in connection with both chlorophyll and
haemoglobin, may not be of physiological im-
portance in both eases.
Emphasis is commonly laid on the chemical
similarity between the chlorophyll molecule and
the hemoglobin molecule, though similarity of
function between the chlorophyll of plants and
the haemoglobin of animals does not seem to
have been definitely shown. An examination

ing with the chemical phases of plant and ani-
mal physiology indicates general interest in
the similarities between chlorophyll and haemo-
globin. It would seem that the identity of
lipochromes and carotinoids is worthy of equal
attention.
The investigation of what the carotinoids of
plants and lipochromes of animals have in com-
mon physiologically would seem to be a hope-
ful line of work. The fact that they may
readily take up oxygen seems to furnish a
starting point for thought and work, which
will be important, whether the results prove
positive or negative.

RATE AND MODE OF SOIL DEPOSITION IN
THE PALOUSE AREA OF WASHING-
TON AND IDAHO
Durine the last eight years the writer has
had the opportunity to observe the formation
of soils on the Columbia Plateau by the wind.
The soils are often a hundred feet deep or
more, and are virtually great dunes of silt
brought sometimes for great distances. The
area where these dunes lie is locally called the
“Palouse,” well known for its deep and very
fertile soils.
Dust storms are frequent, and, curiously, the
dust deposited is generally not raised near the
place of deposition. It comes from an area
of widely different characteristics. This ac-
cords strictly with Richtofen’s theory of loess.
The loess is formed when the wind moves par-
ticles of silt from an arid or semiarid area and
deposits them in a more humid one. Once de-
posited upon the moister land, the silt particles
are not raised again but become a permanent
acquisition to the more humid area. Two fac-
tors cause the permanency of the deposit, first
the moisture in the soil causes coherence in the
deposited mass, and secondly the heavier vege-
tation forms an entangling mesh. Shaler noted
the same conditions prevailing in the formation
of loess on the upper course of the Missouri
River in Montana.
In the Palouse great dust clouds flying high
in the air often nearly obscure the sun at a
time when the soils for many miles around are
SCIENCE
[Vou. LV, No. 1413
too damp to be blown. A rain or snow fall
then clears the atmosphere, carrying the dust
particles to earth, and they do not rise again.
At the present time drifting seldom takes place
but in the past it must have done so. Other-
wise the dune shaped hills extending at right
angles to the direction of the prevailing winds
can not be explained. Thus the deep soils
over the lava plains between the Columbia
Valley and the Bitter Root Mountains have
been formed at the expense of the drier eastern
slope of the Cascade Mountains and the
Columbia Valley.
To measure accurately the amount of soil
brought into an area annually is well nigh
impossible. Only under particular conditions
is it possible to measure that brought in by a
single storm. To do so it is necessary that the
soils upon which the deposit takes place be not
moved by the wind bringing in the dust. Once
deposited, the material must not be lifted again
by the same wind, and that brought to earth
must be kept separate from older deposits.
A particularly favorable situation for mak-
ing measurement was presented over the east-
ern part of the Palouse on January 29, 1917,
and at that time a series of collections was
begun at Moscow, Idaho, by the writer. From
that date to March 23 four dust falls took
place, upon all of which measurements were
possible. On the afternoon of January 28 a
fall of pure white snow took place. The fol-
lowing morning it was covered with a coat of
chocolate brown dust of variable thickness. At
the time practically the whole area was covered
with snow. The dust therefore must have been
carried nearly a hundred miles and probably
was carried twice that distance.
Measurement of the amount of material de-
posited was made by collecting the dust covered
snow from five different areas of average con-
tour, each of four square feet in area. The
snow was melted, the water evaporated and
the dust weighed. From the result the deposit
upon an acre was calculated as’ 140 pounds.
Similar dust falls oceurring on March 21, 22, 23
brought, respectively, 196 pounds, 184 pounds
and 585 pounds per acre as measured in the
same way. ‘The total for the four dust falls
is 1,105 pounds in 55 days or approximately
' JANUARY 27, 1922]
7,500 pounds per aere per year. This deduction
of course assumes that the dust falls oceur with
equal frequency throughout the year. Recog-
nizing that such an assumption is not warrant-
ed, we have made careful observation for the
last three years to estimate whether the caleu-
lated amount might be below or above the
actual. And though accurate measurements
have been impossible we are convinced that at
least the amount given is deposited in this way
each year. The annual accumulation, how-
ever, does not differ widely from this figure.
Many times repeated determinations of the
weight of an acre foot of this soil show it to be
very close to 2,450,000 pounds per acre. At
the rate of accumulation just given it would
require 326 years for the deposition of one
foot, or approximately four inches is deposited
in one century. This is four times as much as
estimated by Free. If no erosion took place
during deposition, according to this estimate,
25,000 years were necessary for the deposition
of the seventy-five feet of soil that covers the
lava beds on this plateau. ;
Considerable further work has been done by
the writer along this line but does not bear
directly upon the mode and rate of formation
of this soil. The work is now to be discon-
tinued unless some one else will take it up.
A fine problem is presented in historical
geology or physiography, and it is hoped that
some person remaining in the vicinity of these
interesting deposits will find time to take up a
study of them. A measurement of the depth
of the soil and more accurate measurements of
the rate of deposition are problems that will
lead to extremely interesting deductions regard-
ing the age of the various lava outflows.

THE AMERICAN SOCIETY OF
NATURALISTS
THe thirty-ninth annual of the
American Society of Naturalists was held in
the Medical Building of the University of
Toronto on December 29, 1921.
At the business meeting the treasurer’s
report was presented, audited, and approved.
The terms of the representatives of the
society in the Division of Biology and Agricul-
ture of the National Research Council were, by
vote, extended six months, so as to end on
June 30, which is the end of the fiscal year of
the council. Dr. Sewall Wright was elected a
representative of the society in the division,
for a term of five years, to succeed Professor
H. S. Jennings. The other representatives
are Professor Leon J. Cole (four years),
Professor Bradley M. Davis (three years),
Professor Ross G. Harrison (two years), and
Professor George H. Shull (one year).
A communication was received from a con-
ference of officers of various biological socie-
ties, called by the National Research Council
to consider the feasibility of a federation of
biological societies, requesting that the Ameri-
ean Society of Naturalists appoint its president
meeting
106
and secretary as delegates to an inter-society
council which is to be charged with formulat-
ing plans for such federation. By vote the
president and secretary were authorized to
represent the society in such a council.
Professor V. E. Shelford, by authority of
the Ecological Society of America, requested
the American Society of Naturalists to assume
part of the burden of a survey of primeval
areas in the Americas. This request was
referred to the executive committee with
power.
The committee on genetical nomenclature, of
which Dr. C. C. Little is chairman, and which
made recommendations at the Chicago meeting,
in 1920, was continued.
Upon recommendation of the executive com-
mittee Professor EK. B. Wilson was elected to
honorary membership in the society. The
following persons were elected to member-
ship: Professor E. C. Case, University of
Michigan; Dr. O. F. Cook, Bureau of
Plant Industry; Professor Vera Danchakoff,
Columbia University; Dr. H. D. Goodale,
Massachusetts Agricultural College; Professor
Robert F. Griggs, Ohio State University;
Professor Joseph Grinnell, University of
California; Professor C. H. Kauffman,
University of Michigan; Professor F. L.
Landacre, Ohio State University; Professor
I. F. Lewis, University of Virginia; Professor
A. D. MacGillivray, University of Illinois;
Professor George J. Peirce, Leland Stanford
Junior University; Dr. Wm.,E. Safford, U. S.
Department of Agriculture; and Professor
E. C. Stakman, Minnesota Agricultural Expe-
riment Station.
The committee on nominations presented the
name of Professor W. M. Wheeler for presi-
dent, and that of Dr. A. H. Sturtevant for
vice-president. These nominees were declared
elected. The other officers for 1922 are as
follows: Treasurer, Dr. J. Arthur Harris;
Secretary, Professor A. Franklin Shull; addi-
tional members of the executive committee,
Professor Bradley M. Davis, Dr. Jacques Loeb,
Professor E. M. East, and Professor Henry E.
Crampton.

SPECIES, PURE AND IMPURE!
THERE has come about in recent years a
profound modification of our conception of a
species in that the botanist, at any rate, is
compelled to recognize the fact that Nature
presents large numbers of successful kinds of
plants that reproduce their types either wholly
or in high percentages, but which clearly have
germinal constitutions of a hybrid character.
These forms may legitimately be described and
classified as species and they are frequently
virile lines of evolution making up groups of
individuals that readily maintain themselves in
suitable habitats. As assemblages of like
individuals, hybrid as to their germ plasm, they
present subjects of study that were not dif-
ferentiated by the earlier naturalists from the
populations of species as they viewed them.
The test of a species, in addition to the
characters that distinguish it, has always been
the evidence that it breeds true to its peculiari-
ties or so nearly true that variations from the
type may be passed over in the descriptive
writings of the systematist as exceptions of
little importance to the mind seeking for order
and rebellious of mental disturbance in his
efforts to express this order in accounts of
faunas and floras over the earth. There are,
then, chiefly as the result of genetical studies
of the near present, two conceptions of species.
There is the pure species breeding true
because its germ-plasm in the diploid condi-
tion carries two similar sets of factors, each
set contributed by one of the parents and each
set having the same genetic make up except
for those factors responsible for sex and for
sex-linked characters. The pure species was
in the main the concept of Darwin and the
older naturalists, and it was assumed to be
representative of species. As viewed by the
cytologist, confident that chromosomes carry
1 Address of the president of the American
Society of Naturalists, thirty-ninth annual meet-
ing, Toronto, December 29, 1921.
108
the factors or genes responsible for inher-
itance, the pure species owes its characteristics
to the fact that parents contribute chromo-
somes of identical factorial constitution and
therefore give to the zygote pairs of homo-
logous chromosomes with the exception that
genes which differentiate sex can only be
present in single sets. Expressed in the
terminology of the geneticist the pure species
is homozygous for all genes responsible for
the species’ characters other than those of sex,
and for sex characters the germ-plasm is
heterozygous in either the male or female indi-
vidual at least where animal forms are under
consideration. The problems of sex deter-
mination from the diploid sporophyte genera-
tions of plants are not yet fully solved. Aside
from the possibilities of factorial mutations
and of mutations due to irregularities of
chromosome distribution a pure species must
develop gametes identical for all genes
other than those of sex, or linked with
sex, because the homologous chromosomes
during the reductions divisions separate from
one another. Some authors would strictly mit
the term species and accept that definition of
Lotsy (1914), “A species is the total of all
individuals of the same hereditary composi-
tion, forming but one kind of reproductive
cell.” I cannot agree with this opinion since
the definition calls for what is almost an
abstraction in higher animals and plants, the
absolutely pure race.
In contrast to the pure species as defined
above is the impure species, the germ-plasm
of which in the diploid condition carries dif-
ferent sets of genes affecting characters other
than those associated with sex. With respect
to these genes the germ-plasm is heterozygous
and through the reduction division there must
take place a segregation of genes with the
result that the impure species cannot produce
a uniform set of gametes, that is, gametes
identical in their germinal constitution. If the
diploid germ-plasm is heterozygous for one
pair of chromosomes other than the sex
chromosomes there would be developed through
the separation of the different chromosomes of
such a pair two elasses of gametes of each sex
provided that reduction proceeds in a normal
SCIENCE
[Vou. LV, No. 1414
manner. If heterozygous for two pairs of
chromosomes there would be developed under
normal conditions of meiosis four classes of
gametes of each sex, and the theoretical possi-
bilities when larger numbers of heterozygous
chromosome pairs are present may be caleu-
lated by the well known genetical formula (27)
when mn = the number of heterozygous
chromosome pairs.
The impure species is therefore clearly
hybrid in its genetical constitution but there
is this peculiarity in its breeding behavior
that it frequently shows little or no evidence
of a segregation of contrasting genes. There
is in such eases no obvious splitting off of
classes through its progeny, but, on the con-
trary, the impure species breeds true or nearly
true to its type. The true breeding of an
impure species must be due to the fact that
only favored types of gametes are able to
produce in conjugation vigorous zygotes
capable of successful development. Further-
more, such favored gametes must carry be-
tween them those genes which in combination
will reproduce the impure heterozygous
germinal constitution of the parent stock.
It is well understood from various plant
material that the failure of a hybrid to pro-
duce a diverse progeny may be due to irregu-
larities at a number of different points in the
life history. The death, the sterility, or the
failure of maturation of classes of gametes
will eliminate the possibilities of development
of whole groups of segregates. Even when
viable classes of gametes are formed some may
leave no progeny because in conjugation they
fail to produce zygotes able to develop a sue-
ceeding generation. In plants the length of
style, or the nature of its tissues, or of its
stigma secretions may operate to check or to
* limit pollen tube growth or the speed of such
growth for some classes of pollen grains and
at this point in the life history prevent the
functioning of pollen tubes carrying particu-
lar types of gametes. Pollen and ovule abor-
tion in greater or less degrees is a very com-
mon phenomenon and is responsible at times
for the elimination of entire classes of
gametes. High degrees of seed sterility and
the weak germination of seeds express the
Frsruary 3, 1922]
failure of certain types of zygotes to develop
a succeeding generation. Explanations for all
of these conditions may be offered by postu-
lating lethal factors, as suggested by the work
on Drosophila, but it is well to understand
for plants how various are the ways in which
lethal factors may block the course of develop-
ment and how numerous are the points at
which they may operate.
The significance of the impure species and
the importance of its place in certain natural
groups is not yet appreciated. Curiously the
plant most conspicuously brought to the front
as one giving rise to new species by mutation
has become one of the forms most thoroughly
studied as an example of an impure species.
I refer of course to the plant Mnothera
Lamarckiana. Presented by De Vries as the
best illustration of his view that pure species
at times pass through periods when they
actively produce by large saltations new spe-
cies, the status of @nothera Lamarckiana from
the first became a subject for sceptical exam-
ination on the part of a body of naturalists
who hesitated to accept De Vries’ conclusions,
and sought for other hypotheses to account for
its remarkable behavior. Bateson was the first
to suggest that the fifty per cent. or more of
pollen sterility in Lamarckiana indicated a
hybrid constitution. Jeffries pushed this argu-
ment with force through comparisons of pollen
sterility in Lamarckiana with similar condi-
tions in various known hybrids. Workers
with Cinothera now generally recognize for
most of their material the presence of very
high degrees of sterility both gametie, as indi-
cated by bad pollen and abortive ovules, and
zygotic, as shown by large proportions of
seeds incapable of germination. Renner has
recently taken the subject of pollen analysis
to a new level by showing that genetic classes
of pollen may be distinguished in Lamarckiana
and in some other cenotheras by differences in
the form of the starch grains within the pollen
cell and pollen tube. Cytological studies of
Gates, Lutz, Stomps, Hance, van Overeem and
others have shown that certain of the variants
thrown by Lamarckiana differ from the parent
type in having higher chromosome numbers
due to non-disjunction. This non-disjunction
SCIENCE
109
seems correlated with a loose association of
chromosomes in Lamarckiana and other ceno-
theras that favors irregularities of chromo-
some distribution at meiosis such as may be
expected in hybrid material. Much breeding
evidence, chiefly from the work of De Vries,
has made it clear that Lamarckiana and other
cnotheras develop two or more classes of
fertile pollen grains which give in various
crosses sets of hybrids in pairs, in threes and
in fours, good evidence of hybrid behavior.
I have shown that with care in the selection of
parent stock it is an easy matter to synthesize
a large-flowered vigorous hybrid with so many
points of resemblance to Lamarckiana that it
would be difficult to separate in descriptive
botany the hybrid from the assemblage of
biotypes that pass under the name Lamarckiana
which, as Heribert-Nilsson has so well brought
out, represents a collective species. Further-
more, this hybrid, an impure synthetic species,
which I have ealled neo-Lamarckiana, has
thrown in each of six generations from selfed
seed similar sets of marked variants, and, as
pollen parent in appropriate crosses, gives
twin hybrids thus paralleling in essentials the
characteristic performance of Lamarckiana. It
is of interest that among the variants from
neo-Lamarckiana there appear occasional
triploid and quadriploid forms comparable to
semi-gigas and gigas. There is no reason to
expect that neo-Lamarckiana will ever be
other than an impure species no matter how
close may be the inbreeding and selection to
type. It breeds true through only a small
proportion of its progeny and we can see
nothing that might change this habit so long
as the line lives. Finally, against the assump-
tion that Gnothera Lamarckiana is a pure
species is the fact that the plant is unknown
as a wild species and there is strong prob-
ability that it arose as a hybrid in England
about the middle of the last century.
These are some of the reasons why genet-
ieists rather generally have come to the con-
clusion that Cnothera Lamarckiana is repre-
sentative of an impure species which repro-
duces its heterozygous constitution because the
viable zygotes produced are for the most part
only those resulting from the union of two
110
different types of gametes, which in combina-
tion reproduce the heterozygous Lamarckiana
complex. Renner in 1914 presented this point
of view, after studies on seed sterility in sev-
eral species of CGinothera, and the conception
of impure Cnothera species was rather fully
discussed in my paper “The test of a pure
species of Ginothera” published in 1915. Thus
certain workers with (Cinothera were fully
aware of the possible significance of gametic
and zygotie mortality in relation to problems
of @nothera genetics some years before
Morgan and Muller in 1918 discussed the
findings of balanced lethals in Drosophila.
Renner deserves particular mention as an
investigator quick to bring the facts of gametic
and zygotic sterility into relation with the
peculiarities of Cinothera breeding. As the
result of his studies and those of other investi-
gators we have reason to feel confident that
most of the wnotheras that have been the sub-
ject of experimental study are impure species,
that is to say, heterozygous in their genetical
constitution.
I am, nevertheless, confident that pure spe-
cies of Ginothera do exist but it will require
much patience in observation, in cytological
analysis, and in experimental crossing to
establish them. The most promising form in
my experience is a line of Hnothera francis-
cana, which has almost perfect pollen and
produces seed about ninety per cent. viable.
This line I have selfed for eight generations
without finding a single departure from the
type. The last generation, grown during the
past summer, was a culture starting with 1,425
seedlings from seeds experimentally forced to
complete germination, a germination per-
centage of 87.3 per cent. In this large culture
1,373 plants survived the vicissitudes of the
season, a loss of only 52 plants mostly as
seedlings. This culture was large enough to
bring out variants if present in the propor-
tions thrown by Lamarckiana, which for some
variants is as high as one per cent., but the
culture gave no exception to the type. Also,
crosses have been made with biennis, muricata
and grandiflora and, when franciscana was the
pollen parent, the results have been uniform
indicating that the pollen
I’, generations,
SCIENCE
[Vou. LV, No. 1414
grains of franciscana are all alike in genetical
constitution. Finally, a cytological study of
pollen formation now in progress by my
former student R. E. Cleland shows a regular
pairing of chromosomes during meiosis in
contrast to the loose association of chromo-
somes characteristic of the same stage in
Lamarckiana and such other cnotheras as have
been studied with the exception of a race of
grandiflora. Thus the evidence of high fer-
tility, uniform progeny when selfed, uniform
F, generations when used as the pollen parent,
and regularity of chromosome pairing during
meiosis all point to the genetic purity of this
race of @nothera franciscana. I present this
line as the purest Cinothera material known
and safer than the race of grandiflora that I
selected twelve years ago and which satisfied
fairly well the tests of a pure species except
that it threw occasional weak dwarfs. This
isolation of an apparently pure species of
Cinothera is a matter of satisfaction and of
some importance for the future of genetical
studies in this group of plants since in the past
we have had no standard material of unques-
tioned purity with which forms could be
mated in tests of cross breeding. My appar-
ently pure race of Cnothera franciscana is
vigorous, easily grown in cool latitudes, and
has a long flowering season, qualities impor-
tant for experimental work, and I confidently
offer it to students of CUnothera as a plant
worthy of their attention.
The interpretation of the breeding behavior
of Gnothera Lamarckiana on the hypothesis
of its impure germinal constitution has
received important and most substantial support
from the investigations of Muller on material
of Drosophila which led to his theory of bal-
anced lethals. The condition of balanced
lethals results when two different lethals are
present, the first in one chromosome and the
second in the other chromosome of a pair.
Thus each lethal is present in a single dose
and the genetical constitution is therefore
heterozygous for each lethal but the two lethals
are in different chromosomes of a synaptic
pair. Since the lethals operate when in double
doses close breeding in such a race will result
in a succession of generations repeating the
Fesruary 3, 1922
heterozygous genetic formula because the
homozygous associations of either lethal block
further development. Such a factorial situa-
tion would maintain a state of constant hetero-
zygosis, the fixed hybridism of an impure spe-
cies. The genetical impurity will be passed
from generation to generation and in this
respect the hybrid will breed true until the
relative positions of the lethals are changed
by a crossover, or the genetical constitution in
these respects is altered by a mutation. A
crossover frees at once recessive characters
which were suppressed by lethals in homo-
zygous condition and the sudden appearance
of such recessives will simulate mutations
although in reality they are manifestations of
a process of segregation.
The theory of balanced lethals offers such a
satisfactory interpretation of the behavior of
certain Drosophila material, behavior similar
in nature to that of @nothera Lamarckiana,
that Muller was quick to suggest the applica-
tion of his results to Ginothera problems. It
should be noted that De Vries as early as 1911
offered a hypothesis essentially similar to the
theory of balanced lethals to account for the
peculiarities of the double reciprocal crosses
between (£nothera biennis and (C£énothera
muricata, forms which, on strong evidence
from the studies of Renner, we now believe to
be impure species. Investigations of my own,
published in 1917, on these hybrids and on
others support the conclusions that lethals are
common in (Hnothera material, but I believe
that conditions are more complex than indi-
eated by the conclusions of De Vries and
Renner. De Vries in recent papers has also
made free use of lethals in offering hypotheses
to cover certain results of his breeding studies
with Cnothera.
Although it is not my purpose to discuss the
mutation theory of De Vries it does seem
important to examine critically the position of
this theory as it is affected by the evidence for
the existence of impure species that are held
to a behavior of pure breeding or almost pure
breeding by lethals which suppress the appear-
ance of segregates. Lethals are not rare in
Drosophila and Ginothera material. There is
reason to suspect that they are common mani-
SCIENCE
111
festations of irregularities in the mechanism
of the organism of so serious a nature that they
interfere with vital processes at some point
in the life history, finally bringing the machine
to a standstill with death as a result. The
workers with Drosophila seem inclined to be-
lieve that much of the phenomena simulating
mutation in their material is in reality the
appearance of characters set free by the
breaking of lethal adjustments which held the
characters latent. Well known workers have
arrived at similar conclusions for C#nothera
material and are not content to accept as evi-
dence of mutations the behavior of Lamarcki-
ana and some other forms when they throw
their marked variants.
An entirely new conception of mutation
phenomena has grown up with meaning very
different from that of the past. M#nothera
material selected by De Vries on the assump-
tion that it illustrated mutation in a pure spe-
cies proves to be highly impure and in genet-
ical constitution exceedingly complex. Prog-
ress in the study of mutations must follow the
usual course in genetical research and rest
upon intensive studies of particular characters,
analyzed and traced through experimental eul-
tures and tests of cross breeding, with the
assistance of cytology at critical points in the
life history, and with constant attention to
phenomena of infertility and sterility. From
the later writings of De Vries it would seem
that the master recognizes the newer trend.
Logically mutations appear to be more likely
from hybrid stock than from pure lines since
heterogeneity of germinal constitution obvi-
ously invites chemical and physical modifica-
tions that might lead to the origin of new
genes or to such changes in old genes as would
result in different expressions of former char-
acteristics. Of particular import is the expec-
tation that lethals most frequently owe their
presence to heterozygous conditions since the
mixing of diverse germ-plasms seems likely to
lead to the breaking down of delicate and
vital adjustments in proportions relative to
the degrees of protoplasmic confusion, and
this means chemical and physical disturbance.
The intensive study of specific mutations with
its effort at analysis to the last degree is a
112
very different matter from that care-free atti-
tude of former years which permitted any
marked variation not easily interpreted to pass
as a mutation. Mutation has become inti-
mately a part of that most fundamental and
illusive problem of biology, the origin of varia-
tion, and mutations apart from the study of
their causation are of secondary interest.
(nothera material and lines of Drosophila
were not the first representatives of impure
species to be isolated by the geneticist. The
blue Andalusian fowl which cannot be fixed,
yellow mice that never have the double dose for
yellow, Vilmorin’s dwarf wheat which throws
talls but fails to produce homozygous dwarfs,
single stocks never homozygous for singleness,
these and other cases are well known and
proven examples of impure species hetero-
zygous in their germinal constitution. Certain
of them, as the blue Andalusian fowl, throw
two homozygous types, in this case the black
and white “wasters.” Others produce one
viable homozygous type. Some impure species
rarely and perhaps never throw homozygous
segregates. All agree in this respect that the
heterozygote, which breeds true to its propor-
tion of the progeny, can not be fixed by
selective inbreeding although as an impure
species it reproduces itself with exactness.
We have briefly reviewed conclusions from
the intensive study under experimental condi-
tions of lines which genetical investigations
have established as representatives of impure
species. Some of the material is obviously of
the sort that would not hold its own under
conditions of open competition in Nature, but
much of it has been derived from forms not
far removed from wild species. There is a
broader aspect of the subject of the hybrid
deserving of examination, namely, the study of
the possibilities of the impure species as a
definite component of faunas and floras.
First of all it is important to bear in mind
that if we accept the eurrent theory which
places the determination of sex as a function
of the reduction or segregation divisions, all
unisexual animals are heterozygous for sex
factors and for such genes as are responsible
for sex-linked characters. For higher animals
this means that either the male or female
SCIENCE
[Vou. LV, No. 1414
carries in single dose a chromosome which is
not paired with an equivalent chromosome.
For higher plants we should expect the diploid
sporophyte generation to be heterozygous for
sex determining chromosomes, a condition for
which as yet we have cytological evidence from
only one type, the liverwort Spherocarpos
studied by Allen and his students, although
there is experimental evidence for this condi-
tion in other liverworts, in some unisexual
mosses, and in certain seed plants, e. g.,
Melandrium. The behavior of sex-linked char-
acters may then be believed to follow an
orderly system in inheritance except as such
linkage is broken or as point mutations appear
in sex chromosomes.
But accompanying the sex chromosomes are
those groups of chromosomes, the autosomes,
responsible for characters not of sex or sex-
linked. The wnisexual state precludes the
possibility of that closest form of inbreeding
possible through hermaphroditism and leaves
the way open to outbreeding subject only to
physiological limitations and to conditions
whereby lethals prevent reproduction. That
Nature has made extensive use of this encour-
agement of outbreeding in various degrees
cannot be doubted, and this is best illustrated
in man, the most mixed and varied of all ani-
mals in the assortment of genes carried by the
individual. It is impossible to believe that any
human is homozygous for the complex of
factors responsible for his individuality.
Even when, as in most higher plants, the
diploid sporophyte generation is bisexual,
there have arisen in many lines of evolution
conditions that make for very high degrees of
genetic impurity. There was a time in the
history of botany when workers, following the
lead of Darwin, devoted themselves to the study
of devices to secure cross-pollination and many
and remarkable are the arrangements described
to encourage outbreeding. Volumes have been
written on this subject and the facts in general
are freely admitted. In wind-pollinated forms
there is even greater opportunity for promis-
cuous pollination unless the shedding of pollen
takes place at such a time that stigmas are
dusted and the ovules self fertilized before out-
side pollen has had an opportunity to reach
FEBRUARY 3, 1922]
the pistil. Perhaps the best examples of wind
pollinated types very freely open to outside
pollination are the numerous races and forms
that make up the collective species Zea Mays.
The studies of East and Jones, Emerson, Shull,
G. N. Collins and others, extending over many
years, show conclusively that corn is usually a
hybrid composite with so many characters rep-
resented hy genes in single doses that purifica-
tion of material by selective inbreeding is a
matter of much time and patience. There
could hardly be a greater contrast in genetical
behavior than that between lines of wheat
which, because they rarely outeross, breed very
true, and races of corn that can only be kept
reasonably true by constant watchfulness,
practiced selection, and a never-ending elim-
ination of products departing from the types.
Self-sterility and the production of weakened
generations following inbreeding, as factors
leading to the establishment of impure species,
have not as yet received recognition propor-
tionate to their importance. Genetical studies
seem likely to show that there are large groups
of bisexual plants the individuals of which are
either infertile when selfed or produce
progenies in successive generations distinctly
inferior in vigor to the wild types. In such
material the species represented in Nature
must be very largely, if not wholly, made up
of individuals cross-bred and genetically im-
pure. It is significant that these conditions
should have been found in that most successful
assemblage, the Composite, frequently cited as
the climax group of plant evolution. The
recent studies of Stout on chicory have shown
the extensive presence of self-sterility, and
that the wild populations must consist chiefly
of outbred and probably heterozygous indi-
viduals. Investigations of J. L. Collins on
Crepis indicate that species of this genus are
impure since progeny from selfed lines show
marked deterioration from the wild stock as
segregation proceeds and forms approaching
purity of germinal constitution are isolated.
Crepis seems likely to prove an assemblage of
impure species similar to that assemblage of
impure races called Zea Mays, and will prob-
ably show the same parallelism of behavior in
reduced vigor and the production of abnormal
SCIENCE
113
types as inbred lines are separated from the
wild population. The interpretation for
Crepis is likely to be that of Hast and Jones
for maize, namely, that inbreeding gives dele-
terious results through the segregation of
types with fewer genes for characters associ-
ated with physiological vigor of expression.
These studies are tending towards conclusions
well established for many cultivated fruits, as
apples, pears, plums, cherries, ete., where self-
sterility among the varieties proves to be the
rule and cross-pollination is necessary for
sexual reproduction through impure lines. It
is hardly possible that chicories and species of
Crepis are outstanding exceptions to condi-
tions in the Composite and we may safely
predict that studies in this immense assem-
blage will reveal wide-spread the presence of
impure species. Self-sterile lines among the
grasses have also been reported, e. g., Lolium
perrene.
There is another type of impure species not
represented in the animal kingdom but common
in certain groups of plants and therefore of
particular interest to the botanist. This is the
hybrid which perpetuates itself by vegetative
means and thus establishes populations in the
wild when its characters are favorable to sur-
vival under the serutiny of natural selection.
The well known principle of hybrid vigor, or
heterosis, may in itself be expected to give to
such hybrids marked advantage. These impure
species hold true to their characters through
asexual reproduction although by their seed
they may produce a large variety of segre-
gates. This principle of the maintainance of a
hybrid by vegetative reproduction is applied in
agriculture when selected lines of potatoes are
propagated from slices of the tubers and
strawberries from plants developed by the
runners, and in fruit culture by the grafting
of choice hybrid varieties.
There have been two notable systematic
studies in America on groups of wild species
in which hybrids are found well established as
impure species. Brainerd’s investigations on
the violets and blackberries show the possibili-
ties of critical studies on the status of species,
making use of the experimental garden and
basing results on genetical analyses. Favored
114
hybrid blackberries, spreading readily by pros-
trate branches that root at the tip, may easily
establish themselves in extensive growths. In a
recent classification of the blackberries of
New England Brainerd and Peiterson isolate
23 hybrid species of the 12 primary species
that are recognized, and they give an addi-
tional list of 32 suspected hybrids. Violets do
not spread so prolifically as brambles but
there are a number of hybrids known which
maintain themselves in Nature by vegetative
growths. Other groups of plants readily
propagating from stems are likely to show
similar proportions of impure species as they
are more thoroughly studied.
With the data before us on the widespread
occurrence in Nature of impure species we
wonder what will be the reaction of systematic
botany. It will be impossible for the manuals
to inelude the many hundreds of lines which
the geneticist may isolate as impure species
although they may be definite units of floras.
There will be little satisfaction in attempts to
identify in the field races which can only be
established by experimental studies of the
garden. Are these impure species to be
grouped for convenience as collective species
regardless of their true positions and relation-
ships? Truly the paths of the systematist and
ecologist have not been made easier by the
progress of genetics.

Through the millions of years represented
by the Tertiary period the mammals differen-
tiated slowly along the conventional lines
which had been previously marked out in large
measure by the reptiles. Some became adapted
to life on the dry plains, others in the forested
river flats, others in the high mountains, the
tree-tops and the tropical jungles. A few of
them learned to fly more or less successfully,
some burrowed under ground and still others
became aquatic. In a general way they did
what the various kinds of reptiles had done
before them in the Mesozoic era, but, on the
whole, they seem to have done it better.
SCIENCE
[Vou. LV, No. 1414
Finally, about the end of the Tertiary period
or later, the next great advance was made by
the genus Homo—an offshoot of one of the
most insignificant groups of mammals. In
consequence of this achievement, the entire
group has been dignified with the name of
Primates. From this offshoot so many sur-
prising things have developed that it is hard
to say which one was fundamental. Undoubt-
edly, one of the first new habits of the human
genus was the use of tools. We may reason-
ably suppose that only one of the less spe-
cialized types of mammals, a creature pos-
sessing flexible fingers and hence the power io
grasp a stone or a club in the hand, could
acquire such ability. Possibly it was this
initial power that gave the first impetus to the
higher progress of the pre-human stock. Be
that as it may, the progress of the human race
seems to have depended largely on the ability to
invent and use other things, such as fur-cover-
ed skins for clothing, the spear and bow-and-ar-
row for the chase, the fish hook, the needle, the
potter’s wheel and so on through the long list of
human contrivances. As Bergson has remarked,
each human tool and machine serves as a new
and additional bodily organ and so multiples
our functional activities to a wonderful degree.
The development. of higher intelligence went
on side by side with this multiplication of
inventions, doubtless, on the one hand, being
stimulated by it and, on the other, making
possible its continuation.
Looking back over the great contributions
which the various animal groups have devised
and elaborated in the vast stretches of geologic
time, and omitting only that of the human
race—which is too new to be impartially
judged—it will be observed that, although each
of these innovations has brought temporary
success and domination to its holders, it has
never heen able to insure the permanency of
the exalted position so attained. Experimenta-
tion seems to be nature’s endless pastime. Her
appetite for it is insatiable; and, no matter
how interesting the results of the trials already
made, there are always more to come. As John
Burroughs once said, “Nature hits the mark,
because she shoots in all directions.”
In that part of the history of man which is
sufficiently well known, we perceive a series of
FEsRuARY 3, 1922]
subsidiary waves of rise, culmination and
decline. Each race or nation seems to have
its day in turn. The causes of such temporary
rises are complex, but in each instance it
appears that some new plan or system or way
of doing things is tried out and its value,
whether great or small, determined. Part of
the new plan may prove to be good; it may be
retained and adopted by succeeding dominant
races. Other parts of the system prove faulty
and eventually cause the downfall of the race.
The injurious features are not likely to be
copied by those that follow.
Without implying that the factors selected
are the only ones, or even the most important
ones, I may draw illustrations from the well-
known histories of nations. The great expan-
sion of wealth and domination among the
ancient nations around the Mediterranean Sea
was due to many and complex causes. Its
industrial basis of energy was largely animal
power—the labor of beasts of burden and of
men. Hxpanding civilization created a demand
for more and more power. To meet this
demand slavery was increased to a point prob-
ably never equalled before or since. To-day
we rely chiefly on fuel power and hence have
been able to dispense with slavery, but in the
days of Rome no other available source of
energy was known. Metals were mined and
smelted by slaves, ships were propelled by
slaves, food crops were raised by slaves, and
even the revenues of government were supplied
in large measure by unwilling tribute from
conquered tribes. For the master people this
scheme produced wealth and power and enabled
them to maintain control for centuries. It
contained within itself, however, a fatal seed
of weakness in the opposing self interests and
disloyalty of the slaves. Given a good oppor-
tunity, both the oppressed tribe and the en-
slaved man were ready to overthrow their op-
pressors and make an end of them.
In the Chinese civilization, which has long
dominated eastern Asia, one of the central
influences seems to me to be ancestor worship.
Other religions have been tolerated and partly
adopted by the Chinese from time to time, but
for the most part they have been merely
grafted upon the ancient stem, forming non-
SCIENCE
115
essential modifications. The requirements of
ancestor worship had many advantages. It is
not hard to trace to this ancient and firmly
held code much of the industry of the Chinese,
their solid, steady qualities, strong family ties,
admiration for personal achievement and cul-
ture, and their respect for authority. Yet
ancestor worship has not proven an unmixed
blessing. It has tied men each to his own
locality. It has made for over-population with
the attendant evils of poverty, ignorance and
even starvation. Above all, it has turned the
faces of the Chinese people towards the past
and inspired them with little interest in the
future. One may well regard this as one of
the most potent factors in making China the
backward nation she has been these many cen-
turies.
The modern peoples of the Atlantic region—
our so-called western nations—are now con-
tributing to the museum of human experiments
that system of living which may be called
“Industrialism,’ whereby through machinery
and extreme specialization of labor each mem-
ber of society is multiplied in activity, wealth
is produced and distributed at an unprece-
dented rate, new inventions follow each other
with bewildering rapidity, and material
“progress” is the watchword. Although this
curve has probably not yet reached its cul-
mination, its more serious defects have already
revealed themselves. Life in the cities is be-
coming more and more artificial and unnatural.
Physical degeneration of the most civilized
nations is making headway. If carried out to
its logical destiny, industrialism as a scheme
of life will doubtless fail like its predecessors.
There are plentful signs that this failure 1s
not far off unless we develop and effectively
apply wisdom enough to modify present dan-
gerous tendencies before it is too late, and
thus save the best of the system for still further
advancement.
It would be strange if, from all we know
concerning the past history of the earth and
its inhabitants, we could not discern some
general scheme or underlying principle which
would help us to fit more successfully into our
environment, and perhaps even to make a
shrewd guess about the future—not of our-
116
selves as individuals, but of our remote
descendants and the earth on which they are
to live. It is obvious that a geologist is on
safer ground if he confines his thoughts to
the domain of geology; and there are some
who may adopt the attitude that it is not
fitting for him to digress from the pursuit of
his strictly geological facts and theories. With
that opinion I frankly disagree. It seems to
me that there are times when the geologist
should consider the relation of his own science
not only to other sciences but to the affairs of
his country and the world at large. I shall
therefore venture to comment upon certain
aspects of those relations which seem to me
worth considering on such an oceasion as this.
The old anthropocentrie attitude of mind,
which characterized even the more progressive
nations up to very recent times and is still
prevalent among humans in general, exag-
gerated the importance of man. All things
were regarded as being intended for his use,
benefit or punishment. The rain was sent to
mature his crops; the forests covered the land
in order that he might have wood; the fishes
of the sea had been thoughtfully provided for
his subsistence; and coal had been formed in
the rocks to give him warmth and power.
Within the last few decades this attitude has
been supplanted to some extent by the evolu-
tionary view, which had been incubated long
before the time of Darwin, but was by his
cogent marshalling of facts given great im-
petus in the world of philosophy. Even to-day
this point of view is generally modified by a
prejudice, which is understandably subtle in
its appeal and extremely difficult to cast out.
Many were disposed to accept the theory of
evolution as applying to the ordinary plants
and animals, but with reservations when it
came to the genus Homo. Man was supposed
somehow to be an exception, more or less ex-
empt from those laws which had governed all
organisms for hundreds of millions of years
up to the time of his advent. It would be
interesting to know how widely this view pre-
vails to-day even among that minority of
human kind who are considered well educated
and philosophically minded. It is tacitly
assumed in certain widely used text-books of
SCIENCE
[Vou. LV, No. 1414
geology, which were current within a score of
years.
Unquestionably we do differ from all other
animals in that some of us have learned to do
things in a high degree which other animals
do only in very low degree or not at all. The
faculty of invention, which can be traced as a
mere rudiment in some of the other mammals,
we have developed in wonderful measure.
Communication of thought by sound and
gesture—a power possessed by many other
mammals as well as birds—we have improved
until we are able to communicate ideas accu-
rately and in the finest shades of meaning by
our vocal language. Many other animals
remember their experiences and profit by such
recollections, but it is the human species
that has vastly increased the store of such
remembered ideas and uses them as material
for thought. Above all, man is the reasoning
animal, fabricating new ideas out of present
observations and the records of the memory.
This is doubtless the greatest innovation pre-
sented to the world by the human species. Can
we impartially estimate its value?
It has often been assumed that these won-
derful powers of the mind are fast giving to
the human race control over its environment to
such an extent that henceforward many of the
laws of evolution which have hitherto governed
the careers of animals and plants will be abro-
gated or greatly modified, so far as concerns
man. It has been supposed, in short, that we
do or will effectively dominate other organisms
and can readily adapt ourselves to those en-
vironmental factors, such as climate, which
we cannot directly control.
In some measure this is true. We have
lately become so accustomed to triumphing
over the lower animals and circumventing the
once impassable barriers of the oceans, the
upper air, and the frozen polar regions, that
it may be opportune to raise the question
whether either domination or adaptation are
destined to go as far as is commonly believed,
and to what extent they are to last—for the
geologist cannot regard anything as permanent.
It is a truism among us that the only per-
manent thing in the universe is change.
In most parts of the world we have by this
FEBRUARY 3, 1922]
time conquered wild beasts to such a degree
that in the more civilized temperate zone coun-
tries we give no thought to them, although in
some parts of India they are still a constant
menace to the ordinary man. But at the other
end of the biologie series are the much more
numerous and more dangerous micro-organ-
isms which assail us on every side. When all
the cireumstances are favorable we can now
control insects, protozoans and bacteria, which
are the carriers or causes of many of our most
dreaded diseases. But it is a hard struggle to
dominate such scourges as plague, typhus,
cholera and yellow fever. They never sleep,
and if, like Russia to-day, a nation finds itself
temporarily unable to maintain the needed
precautions, its boasted control soon vanishes.
We have learned to overcome the isolation
of space on land and sea, to move about more
rapidly than any other animal, to fly higher
than any bird has ever gone, and to maintain
summer heat in the coldest winters; but in
order to do so and by virtue of this expansion
of our activities, we are rapidly depleting the
earth’s storehouse of materials. We are assured
by those who have most carefully studied the
subject that the liquid energy of petroleum
will not serve us adequately beyond this gen-
eration; copper for our wonderful electrical
systems should last somewhat longer; and coal
some centuries or even thousands of years. But
what is ten thousand years in the life of a
race? Other sources of energy are known and
we may yet learn to use them profitably; but it
is well to remember that the continuance of our
type of civilization on anything like its present
seale is absolutely contingent upon the suc-
cess of such attempts. It is not merely a hope
but a necessity, that should convince even the
dullest mind of the need of incessant and ex-
tensive research with such objects in view.
We have organized manufacturing, trade
and commerce to such an extent that millions
of people may now be supported in towns
and cities, and the average population per
square mile multiplied far beyond what was
possible only a few centuries ago. Through
the application of science we have almost
banished many diseases and have greatly re-
duced the usual death rate; and now we are
SCIENCE
117
hopefully attempting to do away with war.
Yet these achievements can hardly be said to
have rid us of our problems, for a crop of
new ones has sprung up—the problems of the
feeble-minded, the degenerate, the insane—to
mention only a few of the most obvious. For
the old diseases, many of which have been part-
ly conquered, we have a great complementary
imecrease in cancer, pneumonia and various
functional and nervous ailments, which are
aggravated by the crowding, the stress, inten-
sity and sedentary nature of modern indus-
tria! life.
No doubt most of us believe that the alge-
braic sum of these gains and losses is a real
advance toward a better state of things. Per-
haps to question the lasting quality of this
advance may not be so presumptuous as we
usually have supposed.
The entire history, not only of the human
race, but of its predecessors from the earliest
known times, has been marked by constantly
increasing complexity of bodily structure,
function and activity. This increase has not
been steady, but pulsating. Evidently we are
to-day witnessing an acceleration of the nor-
mal increase in the complexity of human re-
lations and action. As our modern civiliza-
tion becomes more and more specialized and
diversified, our relations to our environment
become more and more complex and our ad-
justments more delicate. One thousand years
ago, who cared whether economic depression
prevailed in countries across the sea; yet in
our present highly specialized condition such
matters have risen to paramount importance.
In the complexity of modern life wide-spread
hardship and loss are caused by the temporary
shutting down of a great electric system or by
the closing of the coal mines; while a general
railroad strike quickly brings on a paralysis
of activity that can not be endured for more
than a brief time without actual disaster. Yet
one hundred years ago not one of these prob-
lems existed. They would have been difficult
even to imagine.
The impetus of development seems always
to carry the process of specialization onward
without hesitation until a stage is finally
118
reached where it is impossible to go farther.
Eventually it would seem that our western
civilization should reach a point when its con-
tinued dominance would depend upon the ef-
fective working of all parts of a machine,
grown far more extraordinarily complex even
than we know it to-day. It is under just such
conditions that slight changes of environment
—using that term in its broadest sense—may
most readily bring about the stoppage of the
entire mechanism. In the hand-operated
printing press used by Benjamin Franklin
less than two centuries ago there was almost
nothing to get out of order. Compare it with
the highly complicated modern printing press
which might cease to function if a single small
serew or gear should fall out of place.
Furthermore, there seems to be a general
tendency for development to go too far—to
exceed the average capacity of the race at that
stage of its evolution. Human history itself is
full of illustrations of this principle. Many
an ancient king of unusual executive and _or-
ganizing ability has easily maintained a great
empire during his own life-time. After his
death, his responsibilities passed on to men of
lesser ability, and the empire soon crumbled
into as many petty states as before. The
Greek Empire of Alexander and the Mongol
Empire of Kublai are familiar examples.
The greatest empire of ancient times, that of
the Romans, was expanded beyond the dimen-
sions which apparently were suited to that
stage of human progress. Without the ready
communication afforded by the modern tele-
graph and the efficient transport service of
the railroad and the steamship, the highly de-
veloped administrative and military system of
the Romans was strained beyond the limit of
safety. It functioned for a time while con-
ditions were favorable, but it was unable to
survive much hostile pressure. No doubt the
solution of many of Rome’s problems is em-
bodied in the modern British Empire. Thanks
to the progress of civilization in the last few
hundred years, the British have been able to
maintain control over a far wider expanse of
territory than any ancient empire.
To-day we see something of the same ten-
SCIENCE
[Vou. LV, No. 1414
deney at work in our huge industrial organiza-
tions, generally built up during the lifetime of
one man and in large measure as a result of
his exceptional ability. That more of these do
not fail after the death of their organizers is
due probably to our better system of demo-
cratic selection of successors trained under the
master himself, whereby the ablest men are
apt to be chosen. Nevertheless, it often hap-
pens that no one of sufficiently large caliber
is available, and hence the enterprise suffers
to a greater or less degree and in some cases
drifts into disaster. There is some reason to
think that our industrial, political and com-
mercial undertakings are even now reaching a
point where they are growing so vast, so dif-
ficult to handle, and requiring so high an order
of ability at various points that they are be-
coming ineffective largely because a sufficient
number of men of first-rate ability can not
always be supplied. It is entirely conceivable
that as this process becomes even more pro-
nounced, the whole structure will in time col-
lapse of its own weight on account of this
factor.
Even if our own particular civilization does
in time collapse and pass into the stream of
history, like the careers of Greece and Rome,
there is no apparent reason why other eiviliza-
tions should not be slowly developed in its
stead. It is probably safe to infer that such
later civilizations will be founded on somewhat
different principles, enabling these successors
of ours to avoid some of the most serious dif-
ficulties with which we are now struggling.
Perhaps they will achieve better success in
those moral and social affairs, which are too
often overlooked in our modern order. But
there is no reason to suppose, however, that
they will not make other mistakes just as dis-
astrous, or in general that they will be exempt
from the inexorable natural law which has.
brought about the ultimate decline of every pre-
vious civilization, each in its turn.
Eventually, after all the latent possibilities
for advancement possessed by the human
species have been exhausted, the race may con-
ceivably sink back to the general level of the
lower savages, which are but little above the
FEBRUARY 3, 1922]
other mammals. In that state it could per-
haps maintain itself for a long period of
time, even though relegated to the less favor-
able parts of the world.
Without transcending the path already laid
out in previous geologic periods, we may logi-
cally imagine also, that in due course of time
—probably to be measured in millions of years,
an entirely new and more highly organized
animal may spring from some ancestral stock
now relatively obscure, and rise, at first slow-
ly and then more rapidly, to even greater
heights of achievement than anything which
lies within the capacity of the human species.
We have briefly examined the sequence of
physical events in the earth’s history and have
found but secant indication of a definite trend
toward an objective point. In the history of
man and other organisms we seem to see, om
the other hand, an evolution from the lower
to the higher—from the simpler to the more
complex. To that extent there has been quite
evidently a general upward curve. It seems
probable, however, that the quantity of organ-
i¢ life has remained more or less the same
since very early times. There has been the
age-long tendency for each species to multi-
ply until its possible habitat was fully stocked
with individuals. As periods came and went
new types appeared and extended their realms,
like wave-cireles on the still surface of a pond,
but compensating extinctions of older types
left room for them. One may picture even the
organic world as a stream, unchanging in
volume, though ever changing’ in composition;
and its end is to us still as invisible as its be-
ginning.

phere, founded and organized as such, is lo-
cated in the metropolis of the Argentine Re-
public. An illustrated pamphlet of fifty pages
describing the museum and briefly outlining
its collections has been published!. It is in a
series of publications issued by the museum,
and forms the basis of this communication.
Argentina is preeminently an agricultural
country. More than half its cultivated area,
64,225,000 acres, is devoted to the growth of
wheat, Indian corn, oats and flax (for seed).
Its vineyards occupy 345,800 acres while
24,700,000 acres are in alfalfa. Cattle and
other domestic animals number about 92,300,000
and in 1918 Argentina exported 1,479,618,000
pounds of meat.
The collections made to illustrate the agri-
cultural resources of the country at the centen-
nial exposition, held in Buenos Aires in 1910,
were so extensive and valuable that a perma-
nent museum was established in which to
preserve them. The suecess which has
attended the foundation and organization of
the museum is due chiefly to the foresight
and untiring energy of Sr. Carlos D.
Girola, agricultural engineer, who has been
its honorary director from its origin. He has
built up, without guide or precedent, an in-
stitution of the greatest value in promoting the
agricultural interests of his country. The
museum now contains more than 30,000 speci-
mens, covering the entire field of agriculture
and is one of the most comprehensive of its
type in the world.
The collections are classified in seven groups
or divisions as follows:
1. Natural Products, such as woods, native
medicinal and forage plants, minerals, soils,
mineral waters, ete.
2. Agricultural Products, including everything
produced on the farm such as wheat and other
cereals, vegetables, narcotic and aromatic plants,
fiber plants, etc. In this group the museum con-
tains 6,000 specimens.
3. Products of Animal Origin, wool, hides,
leather, ete.
4. Products of Agricultural Industry, flour,
sugar, tannin, dried and canned fruits and vege-
tables, ete. :
5. Products of Animal Industry, milk, but-
ter, cheese, bees and bee products, poultry and
120
poultry products, silk culture, game, fish, diseases
of animals, ete.
6. Agricultural Machinery, tools and appli-
ances used in agriculture.
7. Rural Engineering, under which are placed
all subjects relating to farm buildings, construc-
tion of granaries, ete.
In the organization of the museum provision
is made for the holding of agricultural con-
gresses or meetings for the purpose of discus-
sing subjects relating to agriculture, and for the
issuing of publications and making exchanges.
Up to the present time the publications include
twenty-five titles, most of which have been pre-
pared by Sr. Girola. Among the subjects
treated are: “Studies of Cotton,’ “Observations
on samples of wheat from the Territory of
Pampa,” “The Cultivation of Wheat in Argen-
tina,” “Spineless Cactus,” “Cultivation of Flax
in Argentina,” “Cultivation of Indian Corn in
Argentina,” “Notes on Argentine Fruit Cul-
ture,” etc. For the most part these papers are
based on the collections of the museum.
The supervision of this museum is under the
directors of the Argentine Rural Society. The
museum staff consists of the honorary director,
curator, assistant curator and two caretakers.
The museum building is located on the
grounds of the Rural Society, in a ver'y at-
tractive section of Buenos Aires, overlooking
Plaza Italia. It is 300 feet long by 90 feet
wide and originally cost $100,000.00. The in-
terior which is well lighted, consists of a main
floor surrounded by a broad baleony.
The annual attendance at the museum, which
is open to the public two days each week, ex-
ceeds 100,000 not including the 30,000 students
which visit it from the schools of Buenos Aires.
These figures demonstrate the interest which
the museum has aroused and the need for such
an institution.
The illustrations in the pamphlet before us
include the museum building, its floor plan and
twenty full page views of the interior, showing
many of the exhibits and the manner in which
they are installed. The collections have far
outgrown their present accommodations, and
plans have been prepared for additional build-
ing to take care of the agricultural machinery
and other new material.

Besides the agricultural museum at Buenos
Aires there are the Danish Agricultural Mu-
seum at Lyngby, near Copenhagen, established
in 1888; the Agricultural Museum at Petrograd,
about which little is known at the present time;
the large and well-equipped museum at Berlin,
and the attractively located and wonderfully
interesting museum at Budapest. The buildings
of this museum at Budapest, constructed at a
cost of $480,000.00, are so designed as to il-
lustrate the Renaissance and medieval periods
of architecture of Hungary. Their interiors
are superbly finished, and the collections, which
may be said to include the agricultural features
of museums of art, history and anthropology,
natural history and commerce, are appropriate-
ly and beautifully installed in the many well-
lighted rooms into which the Renaissance and
Gothie buildings are divided.
The museum at Buenos Aires should not be
compared with those institutions which have
been built and liberally supported by the state.
Great riches are not indispensable. An agri-
cultural museum properly located for meeting
its purposes would, by well directed effort and
with the friendly cooperation of those engaged
in agricultural industries, quickly secure collec-
tions. With such collaboration an equipment
may be acquired that will equal or possibly
excel in practical importance that which money
could buy.
Like Argentina in South America, Hungary
in Europe is essentially an agricultural coun-
try, and it is interesting to note that in the one
case the material and exhibits that formed the
basis of its collections were assembled for an
exposition commemorating the hundredth anni-
versary of the country’s existence as a nation—
in the other instance the collections commem-
orated its thousandth anniversary, the National
Millennial Exposition held at Budapest in 1904.
Our hundredth anniversary, commemorated by
the exposition held at Philadelphia in 1876, has
passed. Argentina has outstripped us in its
agricultural development by the establishment
of a permanent agricultural museum. Without
any reflection upon the progress and present
status of agriculture in Hungary, which is most
commendable, let us hasten to follow the ex-
ample of our sister Republic in South America

SCIENTIFIC EVENTS
THE WILLIAM BARTON ROGERS SCIENCE
HALL OF THE COLLEGE OF WILLIAM
AND MARY
An advisory committee of prominent men,
most of whom are trustees or alumni of the
Massachusetts Institute of Technology, has
been formed in the interests of a movement to
provide for the erection at the College of
William and Mary, in Virginia, of the William
Barton Rogers Memorial Science Hall, in honor
of the William and Mary graduate who found-
ed the Massachusetts Institute of Technology.
The members of the committee are T. Cole-
man DuPont, Wilmington, Del., Charles W.
Eliot, Cambridge, Mass.; Samuel Morse
Felton, Chicago, Ill.; Francis Russell Hart,
Boston, Mass.; Charles Hayden, New York,
N. Y.; Otto H. Kahn, New York, N. Y.; Hugh
MacRae, Wilmington, N. C.; Eliakim Hastings
Moore, Chicago, Ill.; James P. Munroe, Bos-
ton, Mass.; Henry Smith Pritchett, New York,
N. Y.; Charles Augustus Stone, New York,
N. Y.; Gerard Swope, New York, N. Y.; Elihu
Thomson, Swampscott, Mass.; Charles Doo-
little Walcott, Washington, D. C.; Edwin
Sibley Webster, Boston, Mass.
The College of William and Mary is the
second oldest college in the United States,
yielding only to Harvard University in this
respect. President Harding, on a visit to the
college on October 19 last, in company with
Secretaries Hughes, Hoover, Mellon and
Weeks, of his cabinet, was greatly impressed
with the traditions and present progress of the
venerable institution. He referred to the
college as ‘the Spartan of American universi-
ties,” having in mind, no doubt, the successful
effort of William and Mary to endure after its
burning in the Civil War, in 1862, shortly
after Dr. Rogers had established in Boston the
great technical school.
William Barton Rogers was one of four
brothers, who were educated at William and
SCIENCE
121
Mary, each in later life achieving great dis-
tinetion in a chosen field of science. He, him-
self, as a geologist, was noted in Virginia long
before he went to Boston. He was the intro-
ducer of the laboratory method of teaching
science in this country, according to Dr.
Charles W. Eliot, who was one of his original
faculty at the Institute of Technology. The
three other brothers were Henry D. Rogers,
who became regius professor of natural history
in the University of Glasgow, Scotland; James
Blythe Rogers, professor of chemistry in the
University of Pennsylvania; and Robert
Empie Rogers, professor of toxicology in the
Jefferson Medical College of Philadelphia.
The sum of $200,000 has been set as the
amount needed for building the Science Hall,
which is designed to commemorate the bond of
friendship between the South’s oldest college
and the North’s foremost institution of tech-
nology. Contributions may be sent to H. B.
Thomas, alumni director, 331 Madison Avenue,
New York City.
RETIREMENT OF PROFESSOR ALBERT W.
SMITH OF CORNELL UNIVERSITY
Tuer following minute has been adopted by
the University Faculty of Cornell University
on the occasion of the retirement of Professor
Albert W. Smith:
In the retirement from his academic functions
of Albert William Smith, dean of Sibley College
and acting president of the university, this
faculty suffers a heavy loss. Few have been so
universally, so deeply, so deservedly loved. An
alumnus of Cornell in the first decade of her
career, he was from early in his undergraduate
days a leader both in study and in manly sports,
and one whom his fellows delighted to honor.
Returning to Cornell in 1886 for graduate study,
he was not again suffered to depart from academic
life. From 1887 to 1891 he taught engineering
at Cornell, in 1891-1892 at the University of
Wisconsin, from 1892 to 1904 was head of the
work in mechanical engineering at Stanford.
Since 1904, when he was called back to Cornell
to succeed Dr. Thurston in the headship of Sibley
College, he has remained with his alma mater,
adding to his directorship the chair of power
engineering; and in 1920, at the retirement of
Dr. Schurman, he became acting president of the
university.
With what loyalty and efficiency he has dis-
122
charged these functions is known to us all. As
an engineer he has stood high in his profession,
and, in conformity with a principle which he has
urged on his colleagues, he has never allowed
himself to fall out of touch with its practical
side. As a teacher and a writer on technical
subjects he has had the power to make intelligible
and clear the abstrusest of problems, and outside
the class room he has not lost touch with his
pupils. As an administrator even his colleagues
know his promptitude, his patience, his consider-
ateness, his remarkable sympathy with the stu-
dents.
But behind and above all these activities has
been to us ever the loftiness of his character and
the exceptional breadth of his culture. He has
been not more engineer than poet; and his love of
literature, his sensitiveness to art, his fine ethical
enthusiasm, his rare modesty and courtesy, have
set their mark on all his work, on all his views.
In his teaching there has been nothing of the
pedagogue, in his administration nothing of the
martinet. We shall remember him, as do his stu-
dents, primarily as man, as friend; and, while
we lose him with regret, we rejoice with him in
the new freedom to which he brings such rich
resources.
THE AMERICAN SCHOOL OF PREHISTORIC
STUDIES IN FRANCE
Tuts school enters on its second year of
activity in July, 1922, under the joint auspices
of the Archeological Institute of America and
the American Anthropological Association. It
makes its appeal for students on the same
footing as the American schools at Athens,
Rome, Jerusalem and Santa Fé.
Both men and women are admitted either
for the period of one year or for a shorter one.
The work is divided into three parts: excava-
tions in a Paleolithic site given the school by
Dr. Henri-Martin, of Paris, to last about three
months; excursions in fall and spring to the
most famous caves, rock-shelters and neolithic
sites of France. These include the Dordogne,
the Pyrenees and the megaliths of Brittany.
The last six months or so of work in Paris
inelude lectures freely offered by the Ecole
@W Anthropologie, museum excursions under the
lead of the director of the school and library
research.
For those who enter for the whole year, two
SCIENCE
[Vou. LV, No. 1414
scholarships are offered for competition, one
of five thousand and one of two thousand
franes; the former will suffice to keep a student
through the year in France, if he can pay his
way thither and back. There may be estab-
lished a small loan fund, and there are occa-
sional opportunities of earning money abroad
while continuing work, but this method is not
advised. At the end of the year a certificate is
awarded, and a thesis should be written and
presented by the student.
The excavations have this advantage that the
students get into the ground themselves and
do their own picking, for it is this rather than
digging. Their duty is to learn what they are
looking for and to understand it when found.
Flint implements, bones of the reindeer, horse,
bison and mammoth occur, and many of them
bear marks of contemporary work with flint
implements; this is rather a “specialty” of the
‘site of La Quina, where the American site is
situated.
It is hoped that many will take advantage
of this offer, and apply for entry to the school.
All such applications as well as those for the
scholarships should be sent as soon as pos-
sible to

THE HISTORY OF SCIENCE AT THE ST.
LOUIS MEETING OF THE AMERICAN
HISTORICAL ASSOCIATION
For the third consecutive year the subject of
the history of science received the attention
of the members of the American Historical
Association at their recent annual meeting at
St. Louis. The session especially devoted to
the subject took the form of a luncheon con-
ference at which Professor Lynn Thorndike of
Western Reserve University presided. Inter-
esting informal addresses were given by Pro-
fessor James H. Breasted, director of the
Haskell Oriental Museum of the University of
Chicago, on the state of research concerning
the science of ancient Egypt; by Professor
Charles H. Haskins, of Harvard University, on
the opportunities for research in the history of
FEBRUARY 3, 1922]
science in European libraries; and by Professor
Archer B. Hulbert, of Colorado College, on
American history and the natural sciences.
Further discussion followed, and it was pro-
posed that the association establish a committee
to facilitate the photographing of material in
European manuscripts for the use of investi-
gators in this country. The question was also
raised of the relations between the American
Association for the Advancement of Science
and the Historical Association. The fact that
this year the two bodies are to meet, respec-
tively, at Boston and New Haven should pro-
vide the opportunity for a joint session or
sessions on the history of science and perhaps
for future common action or cooperation.
Papers of interest to students of the history
of science also were read at other sessions at
St. Louis. At the conference in Medieval His-
tory Professor Louis J. Paetow, of the Uni-

It is to be noted that there were 158 more
members in good standing on September 30,
1921, than there were on the preceding Sep-
tember 30, and that the total enrollment was
greater on the latter date by 105. The total
enrollment suffered a sudden decrease (of 705)
on October 1, 1921, by the dropping of the
names of all whose period of arrearage be-
came over two years on that date, and this
loss has since been increased, by deaths and
resignations, to 971. To offset this, 881 new
members were enrolled up to January 14, and
16 members were reinstated.
It is gratifying to note that the annual dues
have been paid much more promptly this year
than ever before. Of the 11,473 individuals
whose names were on the roll January 14,
8,381 had paid their dues for the current year
and were therefore in good standing.

DISCUSSION AND CORRESPOND-
ENCE
ABRAHAM COWLEY AND THE AGRICUL-
TURAL COLLEGE
I HAvE recently come upon a very interesting
piece of history relating to agricultural educa-
tion, while re-reading the essays of Abraham
Cowley. The paper on agriculture in volume
II of the 1707-1712 edition of his works con-
tains one of the first recorded recommendations
that I can find regarding the organization of
agricultural colleges. In that essay he has
the following to say:
Did ever a father provide a tutor for his son
to instruct him betimes in the nature and im-
provements of that land which he intended to
leave him? ...I1 could wish (but can not in
128
these times much hope to see it) that one college
in each University were erected, and appropriated
to this study, as well as there are to Medicine,
and the Civil Law. There would be no need of
making a body of scholars and fellows, with cer-
tain endowments as in other colleges. It would
suffice, if after the manner of Halls in Oxford,
there were only four professors constituted (for
it would be too much work for only one Master,
or principal as they call him there) to teach these
four parts of it. First Aration, and all things
relating to it. Second, Pasturage. Thirdly,
Gardens, Orchards, Vineyards, and Woods.
Fourthly, All parts of Rural Cconomy, which
would contain the government of Bees, Swine,
Poultry, Decoys, Ponds, ete., and all that which
Varro calls Villaticas Pastiones, together with
the sports of the field and the Domestical Con-
servation and uses of all that is brought in by
Industry abroad. The business of these Profes-
ers should be... to instruct their pupils in
‘the whole method and course of this study, which
aight be run through perhaps with diligence in a
year or two.
The above essay was written about the year
1659 to 1665, and it is very interesting to note
that till more than a century after, in 1796,
was a Department of Rural Economy organ-
ized at Oxford, and Professor John Sibforth
elected to be the first head of the department.
We do not find references to agricultural col-
leges again, however, till the beginning of the
nineteenth century. It will therefore be ob-
served that Cowley was distinctly in advance
of his times. Bacon had suggested schools for
experimental research, but did not suggest the
idea of an agricultural college. We do unques-
tionably notice Bacon’s influence on Cowley in
many respects, and especially in his “Proposi-
tion for the Advancement of Experimental
Philosophy.” In the organization of the
Royal Society in 1662, Cowley evidently saw a
partial realization of his philosophy as out-
lined in the “Proposition,” and he became one
of the original members of the society.
Heretofore we have known Cowley the poet
and Cowley the essayist, but he has not before
been known as Cowley the scientist, and
Cowley the educator. A modern eritie has
said of him that he had “delicacy of feeling
and unfeigned enthusiasm for the nobler and
purer joys of life, for great literature, friend-
ship, science, and nature.” In this fair esti-
SCIENCE
[Vou. LV, No. 1414
mate by Dr. Gough, we have Cowley the
scientist, as well as the poet and essayist.
In reviewing the early agricultural literature,
I find references to a “Colledge of HExperi-
ments,” by Gabriel Plattes in 1639, and “An
Essay for Advancement of Husbandry Learn-
ing: or Proposition for the erecting Colledge
of Husbandry, ete.” by Samuel Hartlib in
1651. In this last the writer had no such clear
conception of the proposition as Cowley had.
Adolphus Speed in his essay “Adam out of
Eden,” 1659, suggests “Diverse excellent Hx-
periments Touching the Advancement of Hus-
bandry.”
If the readers of Scimnce have more de-
tailed information on this matter I should
like them to offer it to the public through
these columns. TO RAS IAG] creeper eet a re eres 200

A MECHANICAL ANALOGY IN THE
THEORY OF EQUATIONS!
To the mathematician the solution of a prob-
lem is the more interesting if it utilizes meth-
ods and principles from fields that at first
glance seem foreign to the one in which the
problem lies. The question of whether a linear
differential equation has algebraic solutions is
sufficiently important to attract attention of
itself, but its answer by reference to the prop-
erties of regular polyhedrons has become a
mathematical classic. Such analogies are not,
however, to be regarded as mere tours de force
whose purpose is only to astonish, or to
appeal to a certain esthetic sense; the instance
just mentioned shows that the new point of
view may disclose wide vistas hitherto undis-
cerned. If there is a choice of terms in which
the analogy may be stated, the formulation
which is most conerete and most striking may
also be the most illuminating.
Such considerations as these, doubtless, have
led to the deseription of what are essentially
vector methods with complex variables in
terms of mechanicai systems. I propose here
to diseuss the progress that has been made by
the aid of such an interpretation in studying
the distribution in the complex plane of the
roots of algebraic equations in one variable.
On the algebraic side the chief purpose of
the investigations to be considered has been to
obtain what may be called theorems of separa-
tion, i. e., theorems which state whether roots ~
of an equation do or do not lie in specified
regions of the complex plane. Such theorems
may also state how many roots lie in the speci-
fied regions, or may give limits, inferior or
superior, for the number of roots thus situ-
ated. These regions may be defined in terms

tion for the Advancement of Science, Toronto,

190
of the roots of other polynomials; we are then
concerned with relative distributions of the
roots of two or more polynomials.
Theorems of separation for real roots of
real equations are numerous, and are among
the most familiar results in elementary mathe-
matics. I need only mention Descartes’ rule,
which gives a superior limit for the number of
roots on the positive real axis, or Sturm’s
method for obtaining the exact number in any
real interval. Rolle’s theorem, in the form
which states that between each consecutive pair
of real roots of a real polynomial f(x) there
lies an odd number of real roots of the derived
function f’(x), is perhaps the most important
proposition concerning relative distributions of
real roots of two real polynomials.
No such progress has been made with sim-
ilar propositions for complex roots, although
the widening of the field of observation from
the real axis to the complex plane vastly
increases the range of possibilities. To be
sure, we have extensions of Sturm’s theorem,
and other methods, both algebraic and tran-
scendental, which give eriteria for the exact
number of roots within a region, but in prac-
tice these prove so cumbersome as to be of
little use. The great desideratum is a body of
results whose simplicity and range of appli-
cations would make them comparable with
Rolle’s theorem, or the Budan-Fourier theorem
in the real case. As Jensen has remarked, the
solution of important problems regarding the
zeroes of transcendental functions may be de-
pendent upon progress in this direction.
The significance of Rolle’s theorem naturally
led to attempts to extend it to the complex
plane almost as soon as the now familiar geo-
metrie representation of complex numbers had
been adopted. A line of attack is clearly indi-
cated by the identity of the logarithmic deriva-
tive
Ud
fe) ie
f(z) Xaien
where f(a) is a polynomial of degree n, whose
roots are @,, @,.-,@, and f’(z) is the first
derivative of f(x). Gauss was probably the
first to give this a mechanical interpretation
which depends on the representation of a com-
plex number z—a as a free vector whose
1

length, |z— al, and direction are those of the
directed line segment from the point which
corresponds to a, or, more briefly, from the
point a, to the point x. The conjugate of the
reciprocal of z—a, which may be denoted by
the symbol Ke i
, corresponds to a vector
having the same direction as the vector —a
but with a length equal to the reciprocal of
x—al. This is precisely the vector which
represents the force at « due to a particle of
unit mass at a which repels with a force whose
magnitude is equal to its mass divided by the
distance. If, then, we take the conjugate of
both sides of the identity of the logarithmic
derivative, we have the theorem of Gauss:
The roots of £/(x) which are not also roots of
£(x) are the points of equilibrium in the field
of force due to particles of unit mass at the
roots of £(x), each of which exerts a repulsion
equal to its mass divided by the distance.
From this result it is but a step, though one
not taken for many years, to the polygon
theorem of Lucas, now sufficiently well known
to have a place in Osgood’s “Lehrbuch der
Funktionentheorie,” but discovered and redis-
covered, proved and reproved in most of the
languages of Hurope—and all the proofs are
substantially the same! This ignorance of the
work of others characterizes even some of the
most important contributions in this field.
Lucas, for example, seems to have considered
himself the discoverer of the theorem of Gauss,
which really antedates his work by many years.
The polygon theorem, in its usual form, is a
theorem of relative distribution which states
that the roots of the derived function f’(x) lie
within or on the perimeter of the smallest
convex polygon (or line segment) which
ineludes within itself or on its boundary all
the roots of f(x). This statement implies that
there is but one such polygon (or line seg-
ment), which reduces to a point if f(z) has all
its roots coincident. In case the polygon of
Lucas does not reduce to a line or a point, the
only roots of f’(x) on its perimeter are mul-
tiple roots of f(z). An equivalent form giving
a separation theorem for the roots of f(z)
states that every straight line through a root
of f’(a) either passes through all the roots of
FEBRUARY 24, 1922]
f(z) or else separates them, 7. e., has roots on
each side of it. This form is immediately sug-
gested by the corresponding mechanical sys-
tem; it is evident that a point of equilibrium
must either be collinear with all the repelling
particles, or else the latter must be seen under
an angle of more than 180° from the former.
This result is only one of many concerning
the relative distribution of roots of f(a) and
f’(a) that may be inferred from the conditions
of equilibrium of our mechanical system; we
have deduced it by taking account only of the
directions of the repelling forces. By con-
sidering their magnitudes as well J. Nagy
(Jahresbericht der Deutschen Mathematiker
Vereinigung, Vol. 27 (1918), page 44) has
obtained a number of interesting theorems of
which the following is one of the most striking:
If ais a root’of the polynomial f(x) of degree
n, and B is a root of f’(x), every circle through
the points B and y = B + (n—1)(B—a)
contains at least one root of f(x). The proofs
given do not, however, make explicit use of
the mechanical analogy. In a paper read
before the International Congress of Mathe-
maticians at Strasbourg J. L. Walsh has util-
ized Gauss’s theorem in discussing the case
where the roots of f(x) lie in two circles.
If the repelling particles exert a force
inversely proportional to the square of the
distance we obtain theorems of relative dis-
tribution of roots in which f’(x) is replaced
by f(a)f"(z) — [f’(2)]*; from a root of the
latter function the roots of f(x) must be seen
under an angle of at least 90°, and the polygon
of Lucas is replaced by one bounded by ares
of circles. Other extensions of this sort sug-
gest themselves, but nothing, so far as I am
aware, has been published along this line.
An immediate corollary of the polygon the-
orem states that all the roots of all the derived
funetions lie within the polygon of Lucas. It
is well known that the centroid of the roots of
f(a) coincides with that of the roots of its
derivative of any order. An often discovered
theorem places the roots of f’(x) at the foci
of a curve determined by the roots of f(a).
In 1912 Jensen, in a very suggestive memoir
on the theory of equations (Acta Mathematica,
Vol. 36), stated without proof a theorem for

191
equations all of whose coefficients are real
which may be regarded as an improvement on
the polygon theorem. If f(z) is a real poly-
nomial its complex roots form conjugate pairs.
The resultant force of repulsion due to parti-
cles at such a pair of points is directed away
from the real axis at a point not on this axis
and which lies outside the cirele whose diam-
eter is the line segment joining the pair; we
designate this circle the Jensen circle of the
pair. At a point within the Jensen circle and
not on the real axis the resultant force due to
the pair is directed toward the real axis, while
on the real axis and on the circumference of
the circle it is parallel to the real axis. Thus
at a point which is neither on the axis of reals
nor within or on the circumference of any of
the Jensen circles corresponding to the com-
plex roots, the resultant force of repulsion due
to the whole system of particles at the roots
of f(x) cannot vanish, for the force due to
each particle on the real axis is directed away
from that axis, and the same is true of the
forces due to pairs of particles at the complex
roots. We thus have Jensen’s theorem: The
voots of f£'(x) which are not real must lie
within or on the Jensen circles of £{(x). To
be more precise, a root of f’(a) cannot lie on
a Jensen cirele unless it is real, or unless it is
a multiple root of f(z), or unless it is also
within or on another Jensen circle.
Since the addition of a constant force par-
allel to the real axis does not change the above
argument, Jensen’s theorem remains valid
when we substitute for f’(<) the function
af(z) + f’(2) where @ is any real number.
Another extension indicated by Jensen con-
cerns the regions within which roots of the
successive derived equations lie, these regions
being defined in terms of the roots of f(z).
Thus the complex roots of f’’(x) are in the
Jensen circles of f’(z), whose centers are on
the axis of reals and whose vertical diameters
are within the Jensen circles of f(x). The
solution of a simple problem in envelopes
shows that all the complex roots of f’’(x) lie
within or on ellipses each of which has a pair
of complex roots of f(z) at the ends of its
minor axis and has a major axis whose length
is \/2 times that of its minor axis. For the
192
rth derived equation the result is the same
except that the ratio of lengths of axes is \/r.
Jensen states that this is also true of the func-
tion g(D) . f(x), where g(D) is a linear differ-
ential operator of order r with constant coeffi-
cients whose factors are all real, and that f(z)
may be an integral transcendental function of
genus zero or one.
In a recent paper (Annals of Mathematics,
Vol. 22 (1920) p. 128), J. L. Walsh notes
some results for non-real polynomials which
follow from considerations that led to Jensen’s
theorem. He also gives an answer to the ques-
tion which at once suggests itself as to how
many roots of f’(x) lie within a Jensen circle
when f(z) is real by a method of interest in
itself, doubtless suggested by Bécher’s treat-
ment of a similar problem which we shall note
later. By allowing all the roots of f(a) out-
side a Jensen circle to move out to infinity,
noting what roots of f’(z) may enter or leave
the circle, and counting those within the circle
at the end of the process, Walsh concludes that
if @ Jensen circle has on or within it k roots
of £(x) and is not interior to nor has a point
in common with any exterior Jensen circle,
then it has on or within it not more than k+1
nor less than k—1 roots of f’(x). Ina paper
not yet published I have obtained a result a
little more precise than this in which, for the
-sake of simpler statement, I will suppose
neither f(a) nor f’(#) has multiple roots. By
the term “root of even index” I designate a
real root of f’(a) between which and the next
real root of f(x) to the right or left there lies
an odd number of real roots of f’(x); if f(z)
has no real roots this term denotes every other
real root of f’(), starting with the least. All
the real roots of even index of f’(x) can be
shown to lie in or on Jensen circles, and every
such circle that has no point in or on it within
or on any other Jensen circle has within it
either just one real root of even index of
f’(x), or just one pair of complex roots of
f'(z). The region covered by a system of
Jensen circles each of which overlaps or
touches some other of the system has within it
the total number of real roots of even index
and of pairs of complex roots of the derived
equation which the cireles would have if they

were separated, but there may be circles of the
system containing no such points. General
criteria to determine whether even an isolated
Jensen circle contains a pair of complex roots
or a real root of even index of f’(a) are lack-
ing, though Walsh discusses special cases, in
some of which we may use a circle smaller
than Jensen’s.
Relative distributions of the roots of a real
polynomial f(z) and of its derivative in vari-
ous special cases have been discussed by H. B.
Mitchell (Transactions of the American Math-
ematical Society, Vol. 19 (1918), p. 43). The
identity of the logarithmic derivative is used,
but the mechanical analogy and Jensen’s the-
orem are not cited.
So far we have been concerned only with
theorems of relative distribution for the roots
of a polynomial and of its derivative. In a
most suggestive paper by Bocher (‘A Problem
in Statics and its Relation to Certain Alge-
braic Invariants,” Proceedings of the American
Academy of Arts and Sciences, Vol. 40 (1904),
p. 469) our mechanical system is generalized
by assigning to particles at points e,, @,,. . e,
masses m,, M,, .. m_ respectively, with the
same law of repulsion as before. Negative
values for the masses are admitted, the repul-
sion becoming an attraction in the case of the
corresponding particles. The field of force is
then given in both magnitude and direction by
re Cae 1 ae
£—e, OG, L—e,
The cases of greatest interest are those in
which the sum of the masses is zero. By pro-
jecting such a system stereographically upon
a sphere (the same result could be established
by inversion on a circle about «), Bécher
proves that a point cannot be a position of
equilibrium if it is possible to draw a circle
through it upon which not all the particles le
and which completely separates the attractive
particles which do not lie on it from the repul-
sive particles which do not lie on it.
A remarkable property of these systems
whose total mass is zero is now developed by
introducing homogeneous variables

If the above expression for the field of force is
reduced to a common denominator within the
parenthesis, the numerator is the product of
x2 and a covariant p of weight 1 of the n
linear forms e”x,—e’x,. The points of equi-
librium are roots of the covariant ¢, and
¢ vanishes at no other points unless two of the
particles coincide. If the points e, are defined
as the roots of a system of binary forms ff,
the masses of all the particles corresponding to
each f being equal, ¢ is an integral rational
covariant of the forms f,, and we are thus led
to theorems of relative distribution for the
roots of a system of forms and those of a
covariant of the system. In particular, if the
system consists of but two forms, the covariant
¢ is their Jacobian; in all cases @ can be ex-
pressed as a polynomial in the ground-forms
and Jacobians of pairs of the ground-forms.
The conditions of equilibrium of the cor-
responding mechanical system can now be
interpreted as theorems of separation for the
roots of the forms. Thus if f, and f, are two
binary forms whose roots are all in circles
C, and C, respectively, and these circles do not
touch or overlap, then all the roots of the
Jacobian of f, and f, are in C, and C,. The
actual number of roots in each circle is ob-
tained by allowing the roots of f, to coalesce
at a point a, and shrinking C, to this point;
during this process C, is always to inelude all
the roots of f,. At the end of this process the
Jacobian has p,—1 roots at a,, where p, is
the degree of f,. We conclude that the Jaco-
bian originally had this number of roots in C,,
and a correspondingly determined number in
C,. The circles C, and C, may be replaced by
cirele-are polygons.
The polygon theorem of Lucas corresponds
to the special case where one of the ground-
forms reduces to Xp.
A ease of especial interest is that where one
of the two ground-forms is linear; we have
just noted a particular instance. The Jacobian
of y,x,—y,x, and f(#,,2,) is the first polar
of (y,,y,) with respect to f. In a series of
papers dating from 1874, to be found in his
collected works, Laguerre had developed sep-
aration theorems for a binary form and its
SCIENCE
193
polars, without the use of our mechanical
analogy. Bécher seems to have been unac-
quainted with these results, which, however,
are directly obtainable from his own. If the
circle C, of the preceding paragraph is re-
placed by the point (y,,y,), we have La-
guerre’s theorem which states that if this point
is outside a circle C, that contains all the roots
of f(#,,2,), then all the roots of the polar
wf, + y2f;, lie within C,. Laguerre gives
i by
this a more striking form by supposing
(#,,”,) taken arbitrarily and determining the
“derived point” (y,,y,) as the point which
makes the polar vanish. Hvery circle through
a point and its derived point either has all
the roots of £(x,, x,) on it, or else there is at
least one root within and at least one root
without the circle. In non-homogeneous vari-
ables the derived point y of a point a with
respect to f(a) is
where n is the degree of f(a). The first ap-
proximation to a root of f(a) being a, the next
approximation by Newton’s’ method is

f’ (x)
light upon Newton’s method in the complex
plane; it replaces x by a point within a circle
on which «x lies, and which surely contains a
root of f(z).
A point coincides with its derived point
when and only when the point is a root of f(a).
Let a be such a simple root, and let £ be its
derived point with respect to F(a), where
f(z) = (a—a)F (a), and the degree of f(x)
is at least two. Since F(a) = f’(a), and
F’(a) = Yef" (a), we have
goa yo f(a)
F'(a) f" (a)
Each cirele through a and £ either has all the
roots of f(a) upon it or else at least one is
within it and at least one is without. There
is thus at least one root whose distance from

Laguerre and others have made interesting
applications of these results to polynomials
194
all of whose roots are real, and to polynomial
solutions of linear differential equations.
Before leaving this phase of our subject we
may note, with Laguerre, that similar the-
orems hold for each of the successive polars of
a binary form with respect to a point. An
interesting field hardly touched as yet is that
of separation theorems for the successive polars
of a form with respect to a sequence of points
defined as the roots of another form. By
taking the two forms in a special case where
they are apolar Grace has proved (Proceedings
of the Cambridge Philosophical Society, Vol.
11 (1901), p. 35) a result equivalent to this:
If the distance apart of two roots «,, %, of a
polynomial f(a) of degree n is 2a, there is at
least one root of £’(x) on or in the circle
aoe 7 :
whose radius is a cot —, and whose center is
n
1%4(a,-+a,). In this paper lack of references
indicates ignorance of Laguerre’s work. The
same result was proved later by Heawood
(Quarterly Journal of Mathematics, Vol. 38
(1907), p. 84) by allowing all the other roots
of f(x) to vary suitably. Here, again, there
is no reference to any other work in this field.
To return to more recent work on the van-
ishing of the Jacobian of two forms f, and f,,
we note two very interesting papers by Walsh
in the Transactions of the American Mathe-
matical Society, in which are discussed cases
where the roots of the ground-forms are in
three circles, instead of two. An added inter-
est is shown to attach to the Jacobian because
the numerator of the derivative of a rational
function
ua) fy(ts2,)
v(@) fa (%yy #2)
is x* multiplied by the Jacobian of f, and f,.
Separation theorems for the Jacobian are then
interpretable in terms of this derivative. The
results of these papers are, of course, only a
first step to the consideration of still more
general separation theorems. The field is the
more interesting in that its investigation
involves a combination of mechanical, alge-
braical, and geometrical considerations.
I must close with only a mention of certain
extensions of the problem we have so far con-

sidered. Thus Bécher, generalizing a method
due to Stieltjes, considers the positions of
equilibrium of a system of free particles of
equal mass in a field of force due not only to
a number of fixed repelling particles, but also
to their own mutual repulsions according to
the same law. If the total mass of fixed and
moving particles is 1, the positions of equi-
librium of the free particles are determined
by the vanishing of covariants, of which some
examples are given by Bécher. These results,
as well as some obtained by adding a force
function K[f(a)], are useful in the study of
polynomial solutions of differential equations.
We must regret that Bécher was never able to
fulfill the hope twice expressed in this paper
that he might be able to return in detail to
these problems which he had merely sketched.
Their investigation requires considerable skill,
but, if successful, would add a new and im-
portant chapter to algebra, with a striking
application of invariant theory.

WILLIAM BATESON ON DARWINISM
Asipe from the fine impression created by
the admirable series of papers and addresses
in biology, zoology and genetics in Toronto at
the Naturalists’ meeting, a very regrettable
impression was made by a number of passages
in the addresses of Professor William Bateson,
the distinguished representative of Cambridge
University and British biology. On the morn-
ing following his principal address the Toronto
Globe (December 29, 1921) published, in large
letters: “Bateson Holds That Former Beliefs
Must Be Abandoned. Theory of Darwin Still
Remains Unproved and Missing Link Between
Monkey and Man Has Not Yet Been Discoy-
ered by Science. Claims Science Has Out-
grown Theory of Origin of Species.” In inter-
mediate type it announced: “Distinguished
Biologist from Britain Delivers Outstanding
Address on Failure of Science to Support
Theory That Man Arrived on Karth Through
Process of Natural Selection and Evolution of
Species. Have Traced Man Far Back but
Still He Remains Man,’ and, in smaller type:
The missing link is still missing, and the Dar-

winian theory of the origin of species is not
proved. This was the verdict of one of the fore-
most British scientists, Professor William Bate-
son, director of the John Innes Horticultural
Institute, Surrey, England, in the course of an
epoch-making address on ‘‘Evolutionary Faith
and Modern Doubts’’ at the general session of
the American Association for the Advancement
of Science, held in Convocation Hall last evening.
While declaring that his faith in evolution was
unshaken, he frankly admitted that he was
‘agnostic as to the actual mode and process of
evolution.’’ Believing in evolution in ‘‘dim out-
line,’’? he pronounced the cause of origin of
species as utterly mysterious.
The speaker then reiterated views expressed
in previous addresses. Again quoting the
Globe:
Referring to the variations occurring in the
different species, Dr. Bateson stated that there
was no evidence of any one species acquiring new
faculties, but that there were plenty of examples
of species losing faculties. Species lose things,
but do not add to their possessions. ‘‘ Biological
science has returned to its rightful place,’’ said
Dr. Bateson, ‘‘namely, the investigation of the
structure and properties of the conerete of our
visible world. We cannot see how the differen-
tiation into species came about. Variation, of
many kinds, often considerable, we daily wit-
ness, but no origin of species. Distinguishing
what is known from what may be believed, we
have absolute certainty that new forms of life,
new orders and new species have arisen in the
earth, but even this has been questioned. It has
been asked, for instance, ‘How do you know that
there were [no] mammals in paleozoic times? May
there not have been mammals somewhere on
earth though no vestige of them has come down
to us?’ We may feel confident there were no
mammals then, but are we sure? In very ancient
rocks most of the great orders of animals are
represented. The absence of the others might by
no great stress of the imagination be ascribed to
accidental circumstances. ’’
Tt is not surprising that the next day the
Globe published a signed letter, under the cap-
tion, “The Collapse of Darwinism,” of which
the following is an abstract:
To an audience rarely paralleled in Canada for
scientific eminence and influence, the famous
Professor Bateson, with amazing frankness, re-
moved one by one the props that have been con-

195
sidered the very pillars of Darwinism. A scientist
of international repute, one of the leading, if not
the leading evolutionist, of the day, he exposed
the weakness of many of the leading planks in
the ‘‘Origin of Species,’? and ruthlessly tore
down one by one the once fondly believed links
in the great chain of Darwinian evolution.
These citations cannot be dismissed as mere
newspaper talk of no import. They are called
forth by the fact that many of the statements
in Bateson’s address as cited below are inaccu-
rate and misleading, especially those relating
to the origin of species, natural selection, and
infertility between species.
It is not true that we do not know how
species originate. The mode of the origin of
species has long been known—in fact, it was
very clearly stated by the German paleon-
tologist Waagen in the year 1869, a statement
which has been absolutely confirmed beyond a
possibility of doubt in the fifty years of sub-
sequent research. It is also true that we know
the modes of origin of the human species; our
knowledge of human evolution has reached a
point not only where a number of links in the
chain are thoroughly known but the characters
of the missing links can be very clearly predi-
cated. The cause of the origin of species is
another matter and has been sought in all
branches of biology and biological research
without an adequate solution having been
found. Charles Darwin’s theory of selection
forms a partial solution of causation and, so
far from being discarded, now rests upon much
stronger evidence than it did when Darwin
enunciated it.
The broad impression conveyed to my mind
by the brilliant series of papers in the division
of Genetics at Toronto is that geneties is
essentially a branch of morphology. It is a
running comparison between the morphology
of the germ cell and the morphology of the
adult. It is in this field, to which Professor
Bateson has lent such distinction, that he fails
to find either the mode or the cause of the
origin of species.
Referring again to the ethical question of
the dissemination of scientific truth, I am
reminded of the precaution pressed upon me by
Huxley from his own experience. He once
196
told me that before delivering any of his pop-
ular addresses he very carefully wrote out
every word he intended to say, lest in the heat
of enthusiasm at the moment he might say
something which would give a wrong impres-
sion of the truth. We men of science are far
too eareless in the application of this Huxleyan
advice, especially in our popular addresses,
which are eagerly read by the public. We
must state the truth so clearly that it cannot
be misunderstood and when we give voice to
our own opinions we should clearly indicate
them as our opinions and not as facts. Bate-
son’s attitude towards Darwinism has been
patronizing ever since he began his evolution-
ary studies. When he refers epigrammatically
in a previous address to reading his Darwin
as he would read his Lueretius he is indirectly
stating an untruth which is caleulated to do
untold harm. In his Toronto address he does
not clearly distinguish between his own per-
sonal opinions based on his own field of ob-
servation and the great range of firmly estab-
lished fact that is now within reach of every
student of evolution who surveys the world of
life under natural conditions.
Since writing the above there has come to
hand a copy of Professor Bateson’s address',
from which the following excerpts may be
made:
Discussions of evolution came to an end pri-
marily because it was obvious that no progress
was being made. Morphology having been ex-
plored in its minutest corners, we turned else-
where. ... We became geneticists in the convic-
tion that there at least must evolutionary wis-
dom be found. . . . The unacceptable doctrine of
the secular transformation of masses by the
accumulation of impalpable changes became not
only unlikely but gratuitous. ... Less and less
was heard about evolution in genetical circles,
and now the topic is dropped. When students
of other sciences ask us what is now currently
believed about the origin of species we have no
clear answer to give. Faith has given place to
agnosticism. .. .
. .. But if we for the present drop evolution-
ary speculation it is in no spirit of despair. . .

place, investigation of the structure and proper-
ties of the concrete and visible world. We can
not see how the differentiation into species came
about. Variation of many kinds, often consider-
able, we daily witness, but no origin of species. . .
... But that particular and essential bit of
the theory of evolution which is concerned with
the origin and nature of species remains utterly
mysterious. We no longer feel as we used to do, .
that the process of variation, now contemporane-
ously occurring, is the beginning of a work which
needs merely the element of time for its comple-
tion; for even time can not complete that which
has not yet begun... .
. .. Meanwhile, though our faith in evolution
stands unshaken, we have no acceptable account
of the origin of ‘‘species.’’ .. .
. . . The survival of the fittest was a plausible
account of evolution in broad outline, but failed
in application to specifie difference. . .. The
claims of natural selection as the chief factor in
the determination of species have consequently
been discredited... .
. .. Even in Drosophila, where hundreds of
genetically distinct factors have been identified,
very few new dominants, that is to say positive
additions, have been seen, and I am assured that
none of them are of a class which could be ex-
pected to be viable under natural conditions.
I understand even that none are certainly viable
in the homozygous state... .
Analysis has revealed hosts of transferable
characters. ... Yet critically tested, we find
that they are not distinct species and we have uo
Treason to suppose that any accumulations of
characters of the same order would culminate in
the production of distinct species... .
Twenty yars ago, de Vries made what looked
like a promising attempt to supply this so far as
Gnothera was concerned. .. . but in application
to that phenomenon the theory of mutation falls.
We see novel forms appearing, but they are no
new species of Cinothera, nor are the parents
which produce them pure or homozygous forms. . .
If then our plant may by appropriate treatment
be made to give off two distinct forms, why is not
that phenomenon a true instance of Darwin's
origin of species? In Darwin’s time it must
have been acclaimed as exactly supplying all and
more than he ever hoped to see. We know that
that is not the true interpretation. For that
which comes out is no new ereation. .. .
. . . If we cannot persuade the systematists to
come to us, at least we can go to them. They
Frsruary 24, 1922]
too have built up a vast edifice of knowledge
which they are willing to share with us, and
which we greatly need. They too have never lost
that longing for the truth about evolution which
to men of my date is the salt of biology, the
impulse ‘which made us biologists. . . .
The separation between the laboratory men and
the systematists already imperils the work, I
might almost say the sanity, of both... .
IT have put before you very frankly the con-
siderations which have made us agnostic as to
the actual mode and processes of evolution. When
such confessions are made the enemies of science
see their chance. ... Our doubts are not as to
the reality or truth of evolution, but as to the
origin of species, a technical, almost domestic,
problem. Any day that mystery may be
solved. ... That synthesis will follow on an
analysis, we do not and cannot doubt.
These passages seem to me to do great credit
to Professor Bateson in so far as they contain
a frank expression of his opinion that up to
the present time neither the causes nor the
mode of origin of species have been revealed
by the older study of Variation, the newer
study of Mutation, or the still more modern
study of Geneties. If this opinion is generally
accepted as a fact or demonstrated truth, the
way is open to search the causes of evolution
along other lines of inquiry.

SCIENCE IN THE PHILIPPINES
EVER since returning from the Philippines
in 1919, after a four-year stay, I have had in
mind the writing of a brief account of con-
ditions as I found them, especially those con-
ditions which are of interest to the research
man, who has wondered how the general
status of his profession, and working condi-
tions in the tropics compare with conditions
in a large city in the northern part of the
United States. My own experience in the
trepics is limited to Manila and vicinity, but
from my reading and from conversation with
others I am of the opinion that conditions in

and other places in the tropics are somewhat
similar, independent of the longitude. I have
purposely delayed setting down my ideas, be-
cause I wished to wait until I could have a fair
perspective in comparing experiences in the
Philippines with experiences in the United
States both before and after my stay there.
There are so many advantages and so many
disadvantages to be taken into account that it is
difficult to say which loeation is the more satis-
factory for scientific work, and of course, the
delights and new interests, and the broadening
of one’s horizon that come about from travel in
the Orient are not to be overlooked. I shall
mention only a few points to be considered
without making any attempt to give them in
the order of their importance.
Climatie conditions are unfavorable in so far
as their effect on physical and mental efficiency
is concerned. The high temperature and high
relative humidity have a tendency to cut down
productiveness. To accomplish a given result
requires much more energy and determination
than in a temperate climate. With the ther-
mometer around 95 to 100 degrees Fahrenheit
and the relative humidity between 90 and 100
per cent., the average individual is not so keen
about performing his daily activities, especially
those which require mental effort.
The general slowing up suffered by the aver-
age individual coming to the tropics from a
temperate climate is so well understood by old
Spanish residents of the Philippines that they
divide all foreigners into three classes. There
are the Ricien Nacidos, those who have been in
the islands not to exceed two or three years, or
literally, the “recently born.” The middle class
consists of those who have been there for five
to ten years, and are beginning to become modi-
fied by the environment. The last class is called
the Platinos, or “bananos.” This class is sup-
posed to have eaten so many bananas that they
have become sleepy and torpid, have lost much
of the industry of a temperate climate and have
settled down and become a part of the general
scheme of life in the tropies.
The separation from scientific societies and
the opportunity to discuss problems and com-
pare notes with others of the same profession
198
must be admitted is a serous disadvantage.
The range of acquaintanceship with persons
engaged in his own class of work is limited and
while there are a few science organizations
these are small in comparison with those that
can be enjoyed in an American city. The re-
sult is that, although one often spends more
time in reading books and journal articles than
if he were here, he finds on his return that a
number of things of importance have transpired
in the science world of which he either did not
hear, or which failed to make much of an im-
pression on him.
Work is often retarded by failing to sup-
plies promptly. It so happened that during
my stay in the Philippines this condition pre-
vailed all over the world, but it was worse there
and is more or less chronic. If supplies are
ordered from the United States, they cannot be
expected in less than three months. To receive
them in such a short time means that the stock
was on hand at the supply house when the order
was received and that there was no delay in
filling the order. The time may be shortened,
of course, by sending a cablegram, but unless
definite arrangements are made and a special
code established, this procedure is not prac-
ticable in general. With the cable rate from
Manila to New York more than a dollar a word
it may be seen that cable messages are justi-
fiable only in rather unusual circumstances. If
the order, when it arrives in Chicago or New
York, is not filled with care and dispatch, an-
other month or two may elapse. Usually it is
not safe to count on delivery of goods in less
than six months. it frequently happens that
the manufacturer or dealer in America does not
realize how long a time is required for an ex-
change of correspondence and will write re-
questing some further information, which
means a delay of another three months, and
so on.
On one oceasion I ordered a pyrometer from
a well known manufacturer in the United
States. The order was sent by mail, but
marked rush, and we hoped to receive the in-
strument within three or four months. At the
end of that time, a letter was received, asking
whether the wall type or table type of galvano-
SCIENCE
[Vou. LV, No. 1417
meter was preferred. This was answered at
once, stating that the table type was preferable.
Several months later another letter came, this
time asking whether we desired the scale to be
graduated in Fahrenheit or Centigrade. By
this time our work had been held up so long
and we were so disgusted by the long delay that
we at once cabled him to send the Centigrade
scale. Practically a year from the date of the
original order, the instrument arrived. Pos-
sibly a little profanity was justifiable when on
unpacking the pyrometer, it was found that he
had sent the Fahrenheit scale. Of course, this
is an extreme case, but serves to illustrate the
serious disadvantage of being separated by
10,000 miles from a supply house where a large
stock of chemicals and apparatus may be ob-
tained immediately. In Manila, as a rule, such
materials are handled by drug stores and the
limited stocks which they carry are available
only to tide over until regular orders can be
placed. Usually the chemicals in stock are pri-
marily for pharmaceutical purposes, and not
many chemically pure reagents are to be had.
Such compounds as ferrous salts seem to be-
come oxidized much more rapidly than here;
although I have seen no actual data to that
effect. Also a number of compounds which do
not take up moisture rapidly in a dry climate,
do so there. On one occasion I bought an ounce
or two of sodium thiosulphate for some photo-
graphic work. After completing the work, I
left the remainder of the chemical in its original
container which happened to be a paper bag
and placed it in a drawer of the library table.
On pulling out the drawer a few days later I
was surprised to find considerable water which
had wet a number of articles in the drawer. On
looking for the source I found that the chemical
was saturated with water and that it was neces-
sary to keep it in a tight container. Chemicals
for use in the tropics should be ordered in small
containers so that if a portion is removed and
the remainder is allowed to stand for a time,
the loss will not be great. Although the cost of
chemicals in quarter-pound bottles is slightly
higher than in pound bottles, the saving and
satisfaction more than repay the extra cost.
The deterioration of instruments and appara-
Persruary 24, 1922]
tus is especially troublesome. Almost any
metal except gold or platinum will corrode
rapidly if given half a chance. A number of
experiences soon bring this to the attention of
a new arrival in the islands. Wire paper fas-
teners must be made of brass if it is desired to
keep pamphlets and magazines in good condi-
tion. After a short time, ordinary iron wire
fasteners corrode to such an extent that the
paper in contact with them is discolored from
iron rust. Ordinary iron wire paper clips rust
so rapidly that after a year or two they cannot
be removed without being bent out of shape.
The frames of cameras made of metal covered
with leather go to pieces in some cases. The
alloy becomes oxidized and pushes off the
leather cover. Of course, it is an easy matter
to remove the covering of oxide and replace the
leather, but in a short time, more moisture has
been absorbed and corrosion has taken place a
second time.
These are trivial things compared with what
happens to delicate physical apparatus of all
kinds. It seems almost impossible to protect
instruments from atmospherie moisture to such
an extent that corrosion does not begin, and if
this continues long enough the piece of appara-
tus is worthless. In many cases the corrosion
does not justify replacement, but does demand
restandardization. In order to get satisfactory
results with pyrometers, galvanometers and the
like it is necessary to restandardize them fre-
quently, and this requires considerable time.
Too long a time would be required to return the
apparatus to the manufacturers for repairs and
restandardization. Even glass lenses of micros-
copes, telescopes, cameras and the like are not
immune. If they are not used for a time, they
become spotted, and often have to be repolished.
Reliable skilled assistants are difficult to ob-
tain. The demand for them is somewhat lim-
ited and every position is filled. However,
there does not seem to be a position vacant nor
a man out of employment. Most of the posi-
tions are filled by Europeans or Americans,
though there is an ever increasing body of
Filipinos trained in science. The difficulty is
that there is very little flexibility to the system.
If one man returns to the States or leaves his
SCIENCE
199
regulary position for any reason, it is almost
impossible to replace him without a long delay
of correspondence back and forth to the United
States and during this time, it often happens
that valuable pieces of research are held up and
interest is lost in them, because no one can be
found to carry on the work.
Thus far I have mentioned only the tribula-
tions of scientists in the tropics and I wish to
protest against any charge of exaggeration.
The account is not overdrawn and all of the
items mentioned have come under my personal
observation, and I believe anyone who has had
experience in the tropics will verify them.
However, there is another side, as I have pre-
viously mentioned. In this connection, the first
thing which I shall discuss is the great interest
and fascination of the various research prob-
lems which one encounters in the Philippines.
The field is comparatively new and if one has
some idea or plan for research, the chances are
that on investigation, he will not find that it
has been trampled over, but that he has practi-
cally a carte blanche. Although extensive re-
search has been carried on at the Bureau of
Science and elsewhere for the past decade or
two, nevertheless the vast number of problems
waiting to be solved have scarcely been touched.
While skilled assistants are few and difficult
to obtain, unskilled help is plentiful. Filipinos
are adapted physically to careful manipulation
and some of them are very satisfactory indeed.
The salary for such a position is much lower
than here and a number of helpers are often
available—which greatly expedites the work.
The climatic conditions make the average
American irritable and perhaps unusually hard
to please, and while he is in the islands he is
likely to believe that his unskilled assistants
possess little merit and are difficult to direct,
but when he looks back at his experiences, he is
likely to change his mind materially and wish
he could have half a dozen muchachos in his
laboratory in the States.
Generally the laboratory is in a building of
only one or two stories. This is very satis-
factory because there is much less danger from
fires and accidents. The uniform temperature
greatly adds to the flexibility of the laboratory.
200
If the train of apparatus to be set up is too
long for the room available, some of it may be
put outside the laboratory. There is no ques-
tion of cold and heat to be taken into account
and during most of the year all that is needed
is protection from the sun. There is always the
advantage of good light and air and freedom
from soot and dirt. Laboratory work is prac-
tically out-of-door work. There is no heating
system, and no frozen pipes to be dreaded.

CHARLES HENRY DAVIS 2ND
CHarLtes Henry Davis 2np, Rear Admiral,
retired, U. S. Navy, who was twice Superin-
tendent of the Naval Observatory, died at
Washington, D. C., December 27, 1921.
He was born in Cambridge, Mass., August
28, 1845, the son of Charles Henry Davis and
Harriette Blake Mills.
Admiral Davis graduated from the Naval
Academy in 1864. From 1875 till 1885 he was
engaged principally in astronomical work, at
first in the Naval Observatory at Washington,
in the Department of Chronometers, and then
in expeditions for the determination of longi-
tudes by means of the submarine cables. Also,
the latitudes of many stations were determined
by Taleott’s Method.
In No. 6, Navy Scientific Papers, published
by the Bureau of Navigation, are given the in-
vestigations by Davis of Chronometer Rates
as affected by Temperature and other Causes.
The results of the longitude expeditions are
presented in three publications of the Navy
Hydrographie Office: with Lieutenant-Com-
mander Francis M. Green and Lieutenant J. A.
Norris “Telegraphic Determination of Longi-
tudes, embracing the Meridians of Lisbon, Ma-
deira, Porto Grande, Para, Pernambuco, Bahia,
Rio de Janeiro, Montevideo, and Buenos Aires,
with the latitudes of the Several Stations’;
also with Lieutenant-Commander Green, and
Lieutenant Norris, “Telegraphic Determination
of Longitudes in Japan, China, and the Hast
Indies, embracing the meridians of Yokohama,
Nagasaki, Vladivostok, Shanghai, Amoy,
Hong-Kong, Manila, Cape St. James, Singa-
SCIENCE

pore, Batavia, and Madras, with the latitude
of the several Stations”; with Lieutenants Nor-
nis and Laird, “Telegraphic Determination of
Longitudes in Mexico and Central America
and on the West Coast of South America, em-
bracing the meridians of Vera Cruz, Guatemala,
La Libertad, Paita, Lima, Anca, Valparaiso,
and the Argentine National Observatory at
Cordoba, with the Latitudes of the Several Sea-
Coast Stations.’
Davis as a Captain was Superintendent of
the Naval Observatory from July, 1897, to
April, 1898, leaving the Observatory to com-
mand the Dixie in the Spanish War. He re-
turned to the Observatory in November, 1898,
and remained on duty there as Superintendent
until November, 1902. As Superintendent,
Captain Davis took an active and successful
part in the completion of the equipment of the
New Naval Observatory and in formulating
plans for the work to be carried on.
In 1904 Davis was made a Rear Admiral, and
in 1904 and 1905 he was the U. S. representa-
tive on the international commission of in-
quiry on the North Sea incident which sat in
Paris.
After service at sea as Squadron Commander,
Admiral Davis was retired August 28, 1907.
He continued to be interested in astronomy
after his retirement, by reason of his achieyve-
ments in science and because of his long service
at the Naval Observatory.
His father, also a Rear Admiral, had twice
been Superintendent of the Observatory and
had established the Nautical Almanae Office.
SCIENTIFIC EVENTS
BRITISH SCIENTIFIC INSTRUMENTS!
Tue exhibition of British scientific instru-
ments held under the auspices of the Physical
Society and the Optical Society at the Imperial
College of Science and Technology, of which a
description was given in our columns last week,
is a timely reminder of the importance of
scientific instruments in the national economy.
Modern civilization is based, and must be in-
creasingly dependent, on the extension of

FrBruary 24, 1922]
scientific knowledge and its applications to in-
dustry; and in these developments scientific
instruments are an essential and predominant
factor.
Of the part played by scientific instruments
in the advancement of scientific knowledge
there is no need to speak. The laboratories of
the universities and kindred institutions where
scientific research is prosecuted would be dis-
abled were they without scientific instruments
of the highest trustworthiness and precision.
The variety and extent of the industrial pur-
poses served by scientific instruments are so
great that there is probably no important in-
dustry in the country which is not dependent
on scientific instruments of one kind or an-
other for the performance of its productive
functions. Moreover, the field of application
of scientific instruments is constantly widen-
ing; the uses of the microscope in the textile
and steel industries, of the polarimeter in the
sugar and essential oil industries, of the pyro-
meter in the metallurgical industry, and of
X-rays in the iron and steel industries, are but
a few of the many examples that could be cited
to illustrate the invasion of scientific instru-
ments into fields of industry in which they were
at one time unknown. That the industries
gain in sureness and accuracy and in a deep-
er and wider knowledge of the fundamental
scientific principles involved is obyious. And
the process continues and must continue. To-
morrow new instruments will be devised and
new uses found for old instruments.
Moreover, as was stated in the leading ar-
ticle published in Naturn of February 10,
1921, the scientific instrument industry, spring-
ing directly from the loins of science, and pro-
gressing as scientific knowledge widens, is one
of the most highly skilled industries we have.
Its expansion means a definite increase in the
numbers of academic and technical scientific
workers and of the most highly skilled artisans;
and the national wealth, in any comprehensive
conception of the term, must be enlarged by
the increase of the numbers of such educated
and skilled classes.
For these and other reasons a flourishing
and efficient scientific instrument industry is
SCIENCE 201
vital to the nation, whether in peace or war.
And, although it is obvious that the users of
scientific instruments, whether in the indus-
trial or academic domain, must not be pre-
judiced or hampered by being unable to ob-
tain the best instruments, from whatever source,
it would be a disaster of the first magnitude
if British scientific instruments should not be
produced equal to the best that the world has
to offer.
AN ENGLISH JOURNAL OF SCIENTIFIC
INSTRUMENTS!
NatuRE may be continuous and the divisions
of time and space no more than artificial ar-
ticulations devised to suit the human intellect.
Nevertheless, physical science is based on
measurement, and proceeds only by the use of
selected units of time, space, quantity, and
so forth. Every new branch of science leads
to the ereation of a new set of units, and
according to the latest theory it would appear
that energy itself is most conveniently regarded
as divided into “quanta”’—measurable and
related units. Many of the most illuminating
advances in theory and actual discoveries of
fact have come about by more refined methods
of weighing and measuring. By these, argon,
radium, and many new elements have been
isolated and identified; by these the structure
of the atom and the new alchemy which trans-
mutes one element into another have been re-
vealed. In every laboratory a new research
implies the devising of new apparatus or the
detection of deficiencies in existing apparatus.
The literature in which such advances in techni-
cal methods are published is scattered all over
the civilized world. It is written in many
languages and at present there is no adequate
system of indexing or recording it. Doubtless
the patent offices contain sufficient descriptions
of improvements with actual or possible com-
mercial value; but even this field is so vast
that applicants have to employ special agents
before they can guess if their claims are novel.
But for a large proportion of the methods de-
vised in the prosecution of research patents are
neither sought nor desired. Sir Richard Glaze-

brook, when director of the National Physical
Laboratory, recognized the waste of time and
the duplication of effort arising from this con-
fusion. He had his opinion confirmed by many
men of science, Government Departments, trade
associations, and private firms. His successor,
Sir Joseph Petavel, and the Advisory Council
of Scientific and Industrial Research have taken
up the question where he left it, and now hope
to found a journal to deal with the methods
of measurement and instruments. A prelimi-
nary number is being prepared under the di-
rection of the Institute of Physics, the Re-
search Department, and the National Physical
Laboratory. It is hoped that the distribution
of this, the cost of which is to be borne by the
Department of Scientific Research, will secure
sufficient support to place the venture on a
permanent basis. There can be no doubt that
the establishment of the proposed journal
would be of value to the progress of all
branches of scientific work.
JOURNAL OF THE OPTICAL SOCIETY OF
AMERICA AND REVIEW OF SCIENTIFIC
INSTRUMENTS
Durine the past few years there has been an
increasing appreciation of the need in America
of a journal devoted to scientifie instruments of
all kinds. This need is due to a number of
The ever increasing volume of scien-
tific material which is being offered for publica-
tion is so crowding many of our journals that
space does not permit an adequate description
of apparatus used. Further, many instruments
and instrumental methods, developed for a
single experiment, can be applied to a variety
of measurements. If described only in econ-
nection with the work for which they were
developed, the description is relatively inaccess-
ible since it is subsidiary to the main scientific
discussion of the article.
In many sciences there is no medium for the
publication of articles describing apparatus
primarily for pedagogical purposes in lecture
demonstrations and laboratory. Such short
articles or notes should serve a very useful
purpose since every real teacher is always on
the lookout for means of improving his teach-
ing. Further, newly developed apparatus and

methods of one science are very frequently ap-
plicable to work in another science. A medium
of publication readily accessible to all would
save much time and energy.
The first steps toward the development of an
instrument journal were taken by the National
Research Council and the Association of Scien-
tific Apparatus Makers of the United States
of America in jointly taking under advisement
the establishment of a new journal for the pur-
pose. After extensive consideration it seemed
unwise to start an independent journal. Final-
ly representatives of the Optical Society of
America, which was publishing a bi-monthly
journal under the title Journal of the Optical
Society of America, were invited to a confer-
ence which ultimately resulted in an arrange-
ment whereby the Optical Society, cooperating
with the National Research Council and the
Apparatus Makers Association, is to add to its
journal a section on scientific instruments. The
enlarged journal is to be published under the
title Journal of the Optical Society of America
and Review of Scientific Instruments, and will
be issued monthly, beginning with May, 1922.
It will be under the direction of an editorial
board composed of Dr. P. D. Foote, Bureau of
Standards, editor-in-chief; Professor F. K.
Richtmyer, Cornell University, assistant editor-
in-chief and business manager; and a repre-
sentative board of associate editors.
In addition to articles on theoretical, ex-
perimental and applied optics in the section
on optics of the new journal, there will be
published in the instrument section original
articles on scientific instruments of all kinds
(z. e., electrical, mechanical, ete., as well as
optical) for research and instruction in chem-
istry, physics, biology and other sciences. The
editors announce that they will be glad to re-
ceive manuscripts for publication, and sugges-
tions as to desirable subject matter to include
in the journal.
GIFT OF THE PROCEEDS OF RESEARCH
FOR RESEARCH
On January 26, 1922, a contract was signed
between The Babies’ Dispensary and Hospital
and the W. O. F. Laboratories Company,
Cleveland, Ohio, in connection with the manu-
PEBRUARY 24, 1922]
facture of S. M. A.—an artificial food adapted
to mother’s milk and developed by Dr. H. J.
Gerstenberger, medical director of The Babies’
Dispensary and Hospital and professor of
Pediatrics of Western Reserve University Medi-
cal School, who has transferred all of his
rights to The Babies’ Dispensary and Hos-
pital.
S. M. A. is said to represent an improve-
ment over the older attempts at making an arti-
ficial food for infants more like human milk
in that it contains a fat that in its saponifica-
tion, iodine, and Reichert-Meiss! numbers is
like the fat of woman’s milk, and in that it
further possesses decided anti-spasmophilic
and anti-rachitic powers. The latter are at least
partly due to the use of eodliver oil in the mak-
ing of the S. M. A. fat.
S. M. A. was fed to dispensary and hospital
infants under careful supervision from 1915
to 1920. During January, 1920, it was made
available to the medical profession of Cleve-
land with excellent results, as can be realized
from the increase in sales per month, being
1,000 quarts at the beginning and 20,000 quarts
during December, 1921. During November,
1920, S. M. A. was put up in powder form,
and a year later was made available to the
medical profession throughout the country.
As a result of this contract the Babies’ Dis-
pensary will receive a minimum of $10,000 per
year. To meet the request of Dr. H. J. Gersten-
berger, the contract contains a clause limiting
the use of the funds to research purposes.
Tnasmuch as The Babies Dispensary and Hos-
pital will be the future department of pedia-
tries of Western Reserve University Medical
School, it is hoped that this accomplishment
will aid in the prompt development of the
pediatric unit of the new medical group of
Western Reserve University.
PROFESSOR J. W. TOUMEY AND THE YALE
SCHOOL OF FORESTRY
APPRECIATION of the part played by Dean
J. W. Toumey, of the Yale School of Forestry,
in securing Mr. Henry S. Graves as his sueces-
sor, and satisfaction in the former’s decision
to continue in the service of the university as
SCIENCE
203
Morris K. Jesup professor of silviculture, is
expressed in a vote passed by the Yale Cor-
poration. It was due to Professor Toumey’s
initiative and wish that efforts were made to
induce Mr. Graves to return to the university as
head of the School of Forestry. The vote of
the corporation follows:
Voted, in accepting, at the request of Professor
James W. Toumey, his resignation as dean of the
School of Forestry, to record the satisfaction of
the president and fellows that he is to remain in
Yale’s service as Morris K. Jesup professor of
silviculture, and to spread upon the minutes of
the corporation an expression of its gratitude to
him for his successful administration as acting
director and then as dean. During this, and due
to his untiring interest and enthusiasm, this
youngest of Yale’s schools has gained largely in
endowment, extended its educational scope, and
added both to its equipment in New Haven and
to its facilities for instruction in the field through
the acquisition of the school forests in Connecti-
cut and in New Hampshire. The corporation
recognizes with pride and gratitude that no other
school of Yale University has enjoyed a more
remarkable and better planned development than
has the School of Forestry under Dean Toumey’s
administration, the close of which is fittingly
marked by the successful consummation of two
projects nearest his heart. One of these is the
aequisition by the School of Forestry of a build-
ing adequate for its needs; the other is the return
to Yale University as head of the school of
Henry 8. Graves, B.A. 1892. The fact that the
movement to bring the latter back as dean
originated with Professor Toumey is but one
example from many which might be cited of his
desire to see the school take advantage of every
opportunity before it and of his constant, loyal
and unselfish devotion to its welfare.

was always greatly interested in the work of
petrology at Yale, and especially in the work
of his friend, the late Professor Pirsson. Dr.
Iddings gave, some years ago, the Silliman
Lectures at Yale University, and he was for
many years connected with the University of
Chicago as professor of petrology. Through a
gift from his~-sister, Mrs. Estelle Iddings,
Cleveland, the entire portion of Dr. Iddings’

not be available, but there will be established
for the next university year a scholarship of
$500 open to a properly qualified student in the
graduate school of the university competent to
carry on research work in petrology. This
scholarship is to be known as the Joseph Pax-

DISCUSSION AND CORRESPOND-
ENCE. }
KILOBAR, KILOCAL, KILOGRAD
In a letter just received from The Meteoro-
logical Office, Professor Whipple very kindly
informs me of the result of a question put to
the Secretary of the Chemical Society regard-
ing the attitude of British chemists regarding
the bar.
While the opinion expressed is to be regarded
as unofficial, Professor Philip says:
“Your letter in reference to the definition of
the ‘bar’ was considered by our Publication
Committee. The general opinion is that very
few English chemists use the ‘bar’ as a unit of
pressure on either basis. There was a feeling,
however, that in view of the use of the ‘bar’
in Langmuir’s papers and other communica-
tions emanating from the same quarter (see
SCIENCE
207
e. g. Dushman in the General Electric Review,
1920-1) English chemists would be more likely
to use the ‘bar’ in that sense than in the sense
employed by meteorologists.”
It will be recalled that meteorologists in 1913,
quite unaware of the fact that the bar had been
accurately defined by Professor T. W. Richards
in 1903, and thinking they were coining a
new word, adopted the bar as the unit of pres-
sure but gave it the value of a megabar. My
friendly correspondent, a meteorologist of
prominence, adds: “This looks as if the con-
fusion is likely to spread. We shall have a
permanent ambiguity like those in the words
billion and calorie.” ‘
To this, I have answered: There need be no
contusion if meteorologists will simply write
kilobar, where they now use millibar.
The practical unit of pressure is 1000 bars,
the bar being the pressure expressed in terms
of force which will give an acceleration of 1
centimeter per second per second to one gram
of matter.
It is the natural basic unit, strietly C. G. 8.
and was in legitimate use by chemists and
physicists 10 years previous to its appropria-
tion by meteorologists.
With regard to the calorie, it will no longer
be necessary to specify the calorie as the gram
calorie or therm. The word calorie by itself
will mean the amount of heat that will raise
the temperature of a gram of pure water from
1000 to 1003.66 Kelvin-kilograds. The larger
unit, much used by engineers, being the amount
of heat required to raise the temperature of
one kilogram of water, can be called the kilo-
cal.
The scale of temperature which has been
used without difficulty at Blue Hill Observatory
for the last five years, makes the thermal co-
efficient of the expansion of a gas (air) at con-
stant pressure .001 instead of .00366.
This is very easily accomplished by making
zero on the scale, the absolute zero (—273.12°
Ac) and making the freezing point of pure
water at megabar pressure, 1000. There are
numerous advantages in the use of the seale.
When used in connection with kilobar pres-
sure, values of temperature and pressure are
208
decimalized; and equations in thermodynamics
require about half the old style multiplication
and division.
It may be noted that, unlike the Fahrenheit
and Centigrade which depend upon the boil-
ing point of water, a variable quantity, depend-
ing upon pressure, and hence not the same
from one day to another, or even from one
place to another, the Kelvin-kilograd uses only
the freezing point. The effect of change of
pressure on the freezing point is so small com-
pared with the boiling point that the correc-
tion is practically negligible.

THE GEOLOGY OF WESTERN VERMONT
In a paper entitled “Studies in the Geology
of Western Vermont,” published in the Twelfth
Biennial Report of the Vermont State Geolo-
gist, pp. 114 to 279, the writer has deseribed
field relations among the lower and middle
Ordovician strata along the eastern shore of
Lake Champlain in the townships of Benson,
Orwell and Shoreham which seem best ex-
plained as great dislocations in the forms of
reverse faults and one or more low-angle thrusts
by which certain massive dolomite and lme-
stone strata of lower Ordovician age have been
broken and moved westward for indeterminate
distances over shales and interbedded black
slates and limestones belonging to the same
geological system, but undoubtedly younger in
age.
Similar phenomena were described also for
the lake region near Burlington, where, how-
ever, thrust phenomena had long been better
known. In the northern areas, so far as
studies had then been carried by the writer, the
presence of lower Ordovician limestones on
middle Ordovician slates seemed largely con-
fined to the islands of the lake, while on the
mainland of Vermont certain siliceous dolo-
mites and quartzites belonging to the Cambrian
system and to the lower Cambrian terrane were
found reposing on black slates with interbedded
limestone bands not very different from those
found beneath the lower Ordovician limestones
SCIENCE
[Vou. LV, No. 1417
on the islands and on the mainland farther
south in Orwell and Benson.
In addition to the description of the more or
less clearly defined deformations just referred
to the writer offered field evidence in support
of the view that similar dislocations may prob-
ably define the fundamental deformational feat-
ures of the rocks within parts of the Taconic
Range, and along the “Vermont Valley” and
the western margin of the Green Mountain
plateau contiguous thereto, although within the
latter-mentioned areas the thrust relations have
been much disguised by normal faulting.
In the summer of 1921 the writer continued
his studies in western Vermont among the
islands of Lake Champlain and along the main-
land in Phillipsburg, Quebec, and in the Ver-
mont towns of Highgate, Swanton, Sheldon,
St. Albans, Georgia, Fairfield, Fairfax, Milton
and Colchester. Although there are present in
these areas certain differences in respect to de-
formation and erosion, with which in some
degree apparently are to be correlated the
former extent and present boundaries of the
lake in its northern portions, and also ceviain
geographical variations, chiefly in the rocks
composing the lower Cambrian beds in north-
ern Vermont, the major thrust relations are
clearly defined. Many interesting structuzal
details were noted.
It is purposed, at the first opportunity, to
continue these later studies thus begun and to
publish a second paper on the geology of west-
ern Vermont, dealing chiefly with deforma-
tional features among: the islands of Lake
Champlain and along the Vermont shore region
of the lake as far south as Shoreham.?

source of sounds, under the heading, “Have
Birds an Acute Sense of Sound Location?” He
closes by saying that he would appreciate any
direct observational data touching upon this
subject. The following is an affirmative an-
swer to his question:
On the morning of September 9, 1921. when
in camp near Kneeland post office, Humboldt
County, California, while I was seated among
some rather tall bushes, watching for sparrows,
a Sharp-shinned Hawk (Accipiter velox) flew
on to a lower limb, some thirty or forty feet
above the ground, of a dead fir tree about
seventy yards away, alighting with its back to-
ward me. While the bird was visible to me
through the small openings among the branches
of the bushes I must have been absolutely
hidden from its view.
Just to see what the result would be I
squeaked in imitation of a wounded bird when,
to my great astonishment, the hawk wheeled as
if on a pivot with remarkable rapidity and
darted in a bee line over the tops of the bushes
straight in my direction. When it reached the
spot directly over my head, and not six feet
above me, it evidently was aware that it had
reached the center of the sound field for, not
seeing anything there to account for the sound,
it shot abruptly up into the air and lit on a
limb of another dead fir so close to me that I
shot it with my 32 caliber auxiliary barrel
with a small charge of No. 12 shot.
The most curious part of this incident is that
the hawk did not stop to listen and analyze
or locate the sound, as might a jay for instance,
but with the first squeak it turned quick as a
flash, and darted with arrowlike speed for the
spot from which the sound emanated; that is to
say on the exact line (more correctly, vertical
plane) between its perch and the spot, as the
height of the bushes prevented it from aiming
its flight quite low enough. It seemed to me
that if my head had been high enough to be
above the bushes it would have struck me.
This was the most remarkable exhibition of
instantaneous precision in locating sound, not
only as concerns direction but also as to rapid-

port.,
Tue latest work of Professor Alfred Lacroix
is a very important contribution to the history
of the scientific men of France in the eighteenth
century, perhaps all the more so that the name
of Dolomieu is not well known in foreign lands.
The book has grown out of the researches
made by Professor Lacroix in preparing the
biographical sketch of Dolomieu which he read
before the Académie des Sciences on December
2, 1918, and which has already been reviewed in
Science. He found a number of Dolomieu’s
letters in the library of the Muséum d’Histoire
Naturelle, and traced out many others in for-
eign libraries and in private hands. The author
remarks that the chief value of those letters he
has selected for publication is that they include
a series, covering a period of some twenty years,
written by Dolomieu to a small number of par-
ticular friends, so that they enable the reader
to follow his life day by day in its more inti-
mate details. The earliest in date of these
letters were addressed by Dolomieu to his pat-
ron, Duke Alexander de la Rochefoucauld,
member of the Académie des Sciences and
colonel of the regiment “De la Sarre,” who was
destined to be assassinated in 1792, almost in
Dolomieu’s arms.
An interesting group of 47 letters are those
written to the Sicilian naturalist Giseni; these
treat at length of the important investigations
of Dolomieu in the domain of voleanic forma-
tions. Other groups of letters are those sent to
210
the Chevalier Philippe de Fay, the truest of
Dolomieu’s friends, to Picot de la Peyrouse,
botanist and geologist of Toulouse, to the great
geologist Saussure, to the Genevan physician
Pictet, to Pierre Picot, professor of theology in
Geneva, and to Frederic Munter, professor of
theology in Copenhagen.
The following extract from a letter to this
last named correspondent, is a characteristic
example. Dolomieu, after passing safely
through the throes of the French Revolution,
was appointed, in 1796, lecturer in geology and
the distribution of minerals at the newly-
organized Heole des Mines. A year later, Jan.
15, 1797, he writes to his friend Munter:?
“The sciences, which were for me formerly a
relaxation, have become a profession which fur-
nishes me the means of livelihood, and none the
less I cultivate them with pleasure. I am chiefly
occupied with mineralogy and geology, and I
give lessons in these branches at the Heole des
Mines during the winter. During the summer
I travel to inspect the mining operations. I
have assumed charge of the mineralogical ar-
ticles of the Dictionnaire Encyclopédique, and I
write articles which are published in various
journals. Thus I employ my time in a manner
agreeable to myself and I advance without much
disquietude toward that. fatal term against
which all human hopes make shipwreck. We
have become so accustomed to the idea of death,
that we now see our last hour approaching with
complete indifference.”
The biographical sketch already noted is re-
printed by Professor Lacroix at the beginning
of the first volume of the present work (pp. i—
Ixxx). To this succeeds the unique record writ-
ten by Dolomieu in 1799, in his prison at Mes-
sina, where he was incarcerated because of his
supposed guilt, as a Knight of Malta, in aiding
Bonaparte to seize the island. It was inscribed
on the margins of the leaves of a book he had
succeeded in obtaining, and which is now a pre-
cious possession of the Muséum d’Histoire
Naturelle (pp. 1-44). The quality of this rec-
ord may be exemplified by the following brief
extract :

renewed the life of the vegetable kingdom and
gave new force to all organized beings, the
environs of Paris seemed too restricted for me,
its atmosphere heavy and offensive
Therefore each year I hastened to the Gaon
ains, and sought on their summits those pro-
found emotions which the contemplation of
very great objects always procures us
Now, confined within a space of twelve feet
long, and ten feet in height and width, I can
only contemplate my own wretchedness and
reflect upon the vicissitudes of fortune and
my strange destiny.”
Fortunately the Italian victories of Bona-
parte opened his prison doors, his liberty be-
ing prescribed in one of the articles of the
peace treaty of Florence, March 20, 1801.
However, his enfeebled health did not long
permit him to enjoy his recovered freedom.
He died at Chateauneuf, November 6, 1801,
but fifty-one years old.
Of Dolomieu’s scientific attainments, Pro-
fessor Lacroix notes that it was principally
in the study of volcanic phenomena that he
left his trace, and asserts that by his researches
concerning Auvergne, he takes his place in the
first rank of those who have recognized and
demonstrated the relations existing between
voleanism and the internal heat of the earth.

DISSOCIATION OF HYDROGEN IN A TUNGS-
TEN FURNACE AND LOW VOLTAGE
ARCS IN THE MONATOMIC GAS
In the course of an investigation of arcing
characteristics of diatomic gases being carried
on in this laboratory, it was found that the
are between a hot tungsten filament and a
plate anode in hydrogen struck and broke at
a minimum of 16.4 volts. This potential is
about that ascribed by Bohr’s theory to the
potential necessary to accelerate an electron —
so that it will dissociate the molecule and ionize
one of the atoms upon impact. In view of the
fact that Bohr’s theory puts the ionizing po-
tential of the hydrogen atom at 13.52 volts
Frpruary 24, 1922
and the radiating potential at 10.14 volts, it
seemed that it should be possible to maintain
an are at 13.52 volts or even as low as 10.14
volts. The failure to maintain an are at these
potentials was ascribed to the insufficient
amount of monatomic hydrogen in the tube.
During the course of this investigation, Pro-
fessor K. T. Compton suggested that it might
be possible to dissociate hydrogen by means
of a cylindrical tungsten furnace which could
also be used as one of the electrodes for the
are. The writer undertook the investigation
of the possibility of this and computed the
per cent. of monatomic hydrogen which would
be in equilibrium with the diatomic gas on the
basis of Nernst’s equation of the “reaction-
isobar.”?. Taking the heat of dissociation to
be 84,000 calories per gram, 8 = 0.000225,
and the chemical constants for the diatomic
and the monatomic hydrogen to be? -3.4 and
-1.6 respectively, the per cent. of monatomic
hydrogen in equilibrium with diatomic hydro-
gen is indicated in the following table:
1000° 1500° 2000° 2500° 3000°
Pressure K K K K K

10mm. .004 169 400 98.8
5.0mm. .002 0.74 26.7 90.4 Dissociation
As it is possible to obtain a temperature of
more than 2000°K in a tungsten furnace, it
seemed that a sufficient amount of monatomic
hydrogen could be obtained to maintain the are
at the lower potentials.
The furnace consisted of a cylinder of thin
sheet tungsten, furnished by the General Elec-
trie Company, mounted on water-cooled leads
and heated by means of an electric current.
A tungsten filament ran axially through the
furnace and was also heated by a current. The
fall of potential in the furnace and that in the
filament were in the same direction and of
nearly the same amount. A potential was
applied between the furnace and the fila-
ment, and was tried in both directions. The
potential of the are was corrected to the amount

between the middle of the two electrodes. Gas
pressures of 0.6, 0.8 mm, 1 mm, and 2 mm
were used.
When the furnace was not heated the are
could not be maintained below the 16.4 volt
point. When the temperature of the furnace
was raised, a point was reached at which the are
would strike at about 16.6 volts and break at
about 14 volts, indicating that the increased
dissociation in the are raised the percentage of
monatomie gas sufficiently so that the are could
be maintained to approximately the ionizing
potential of the atom. At still higher furnace
temperatures the are could be made to strike
and break at about 13.5 volts and the results
when plotted showed also unmistakable evi-
dences of ionization at about 10.3 volts.
Curves were obtained showing three sharp
breaks in the neighborhood of 10.3, 13.2, and
16.2 volts. With the furnace at a very high
temperature the are would strike at about 14
volts and break at 11 volts. It seems certain
that the are struck at the ionizing potential
of the atom and was maintained as low as the
resonance potential of the atom. There was a
considerable amount of tungsten “sputtered”
on the walls of the tube, and from this it was
concluded that the temperature of the furnace
must have been 2000° to 2500° K. The results
seem to indicate that the percentages of disso-
ciated hydrogen calculated above are approxi-
mately correct.
These results constitute, it is believed, the
first direct experimental proof of the correct-
ness of the values of the radiating and ionizing
potentials predicted by Bohr’s theory for the
hydrogen atom, and of the interpretation of the
lonizing potential of the molecule as due to its
dissociation plus the ionization of one of the
atoms.
A complete report of these experiments will
be published later. The apparatus will also
be used to study the ares in other gases and
for investigating the excitation of the spectra
of substances at high temperatures.

A SIMPLE METHOD OF DEALING WITH
ELECTRIFIED MICROSECTIONS
ELECTRIFICATION of the sections is a frequent
cause of trouble in microtomy. The sections
when cut fly back into the paraffin block when
the block rises for the next cut, or, if a short
ribbon has already been cut, this flies to the
knife, twists and curls, or “bunches up” on
the knife in such a way that it is an exceedingly
wearisome task to seriate the sections, and re-
quires almost infinite care and patience. The
causes of electrification may be various. It is
owing either to atmospheric conditions or to
faulty methods of infiltrating or blocking. The
use of a metal drum on which the sections may
be wound as cut, reduces somewhat, as is well
known, the difficulty experienced because of the
electrification of the sections. The suggestion
of Guyer (p. 47 of his revised ed. of Animal
Micrology 1917) to postpone cutting till a more
favorable time is not very satisfactory to one
who is compelled, because of press of time, to
cut continuously. The following simple device
T have used with electrified sections and have
found very satisfactory. The labor of mount-
ing such sections, by its use, has been very much
reduced, and I believe it will be quite generally
serviceable.

rotary microtomes for the cutting of serial sec-
tions. It consists of a thin blade of celluloid

logical supply-houses does very well). This is

screwed flat against the section-knife by means
of the usuai knife-holding screws of the car-
riage. (Fig. 2). A long narrow strip of thin,
tough paper is passed up between the celluloid
blade and the microtome knife, until about 3
em. of it protrudes above. After the paraffin
block has been properly trimmed and adjusted
to the knife, the sections are cut, and as each
one is cut, it is attracted and held by the paper-
strip which is pulled along with the fingers so
as to produce a series. (Fig. 2). When the
strip is nearly filled with sections, it is taken
and fastened to the table or board with thumb-
tacks, to keep it from curling, and another strip
substituted.
By means of this extremely simple device,
the writer has found it possible to cut with ex-
cellent seriation material which otherwise, ow-
ing to electrification, would have been impos-
sible.

Filter cloth and its relation to filtration: ALVIN
ALLEN CAMPBELL. Filter cloth is a very im-
portant consideration. Principal kinds are made
of cotton, wool, jute, hemp, nickel and monel
metal. Cotton duck the most used, but being
replaced by materials of longer life though not
necessarily better filterers. Solids really are the
filter medium, the cloth is merely the retaining
wall. The combination of strength, fineness and
rapidity is what is wanted. Life of cloths de-
pends on chemical action tending to destroy its
use. Considers monel metal the best cloth mate-
rial in most cases. Gives interesting list of vari-
ous acids and salts and whether or not monel
metal is recommended. Warns against electro-
lytie action on monel cloths, citing potassium
permanganate as a case in point. Gives opinion

as to round, square or rectangular openings. Wire
cloth a failure in filtering certain colors. Filter
aids work well with wire cloth. Does not recom-
mend that wire cloth be rolled.
Filter aids: C. P. DrerurtH. The term filter
aid is defined and a list of materials used for
this purpose given. Materials to which the term
Kieselguhr is applied are discussed. Author
divides filtration problems into three classes on
the basis of whether the solids in the mixture are
rigid, non-rigid or a combination of the two. A
discussion is given as to the manner in which a
filter-aid may be used and the advantages accru-
ing therefrom, in each of the three cases. Desir-
able characteristics in filter-aids is given. Filter-
aids are said to improve clarity of filtrate, reduce
power consumption, reduce loss of liquid in cake,
reduce labor in cleaning cloths, increase life of
cloths, and increase rate of flow.
The feeding of filters: J. F. Sprincer. Defines
‘‘feeding’’ as consisting of the transmission
under pressure of the unfiltered liquor from a
point where it is received from storage to the
inlet aperture of the filter. Necessary equipment
is pipe-line, pump and power. Suggests that in
order to keep pump and valves clean from solids,
precipitation of the solids when possible ought to
be done either in filter or between pump and
filter. Suggests possibility of solids being dis-
solved before reaching pump and then again pre-
cipitated between pump and filter. Describes
feeding devices made of various materials and
the corrosive action of certain substances there-
on. Discusses suction, gravity and pressure
feeding and appropriate apparatus. Steam,
power-reciprocating, centrifugal pumps and
montejus are dealt with.
Fundamental laws of filtration with sugges-
tions regarding research work: D. R. SPERRY.
The writer develops a formula which is a state-
ment of the fundamental laws governing filtra-
tion. This is done to form a foundation upon
which filtration may be put upon a scientific
basis. Definitions of filtration, porous mass,
filter-base and filter are given. Three indispen-
sable conditions of filtration are difference in
pressure between the two sides of the porous
mass, a filter base and a filter. A study is made
of the phenomena of filtration and it is found
that the rate of flow of filtrate at any instant
equals the rate of flow through the cake at that
instant were there only liquid above the cake.
With this as a basis a study is made separately
of the laws of flow through cake and the laws of
building up of cakes. The two expressions are

of filtration as follows: Q = WPT + N2 —N

WY = Ro’ Ne= Re Units for measuring K,
the rate of deposition, and R, the resistance of

follows.
Washing filter presses: Bustack A. ALLIOTT.
Washing is used to recover a valuable liquor from
the solid particles which retain it or to free such
particles from impurities dissolved in the adher-
ing liquor. Generally wash water ought to be as
little diluted as possible; hence the smallest
quantity should be used. Adsorption, capillary
diffusion, formation of chemical compounds, and
colloid formation on removal of electrolytes are
disturbing factors in washing. Each of these
factors is discussed. Simple washing involves too
much space and care. For best washing results
plate and frame type filters should be used with
thorough washing. Air vents should be provided
at top of wash chambers, wash must leave at top
of press and enter at bottom. Considers various
mechanical appliances for washing, hydrometer
bowls, wash pumps, and montejus. Under ideal
conditions wash equal to one displacement volume
should effect complete washing. A number of
washing results is given from actual practice,
showing displacements volumes of 1.6 to 5.5.
Describes stage washing. Gives a number of
interesting wash curves, and cuts of mechanical
appliances for washing.
Pulp or filtermasse filters: E. KE. Frncu.
Divides filters into two classes—those whose pri-
mary purpose is for clarification and those for
retaining solids. The pulp filter belongs to the
first class and uses cellulose as a filtering medium.
Gives a short history of the pulp filter. Origin
was probably in Germany. Gives a list of various
substances used as a filter-masse with appropriate
remarks. Concludes pure cotton masse the best.
Describes method of preparing and using filter-
masse. Pulp filters can be constructed for
handling liquids which must not touch the ordi-
nary metals. Discusses advantages of a clear
product for manufacturer. Filtration in pulp
214
filters is a violent agitation which may cause pre-
cipitation requiring re-filtration. Gives methods
of treating liquids by pasteurizing, chilling or
settling. Mentions filtration of glue and gelatine.
Atkins-Shriver automatic filter press: H. D.
Arxins. This apparatus is a modified form of a
round, center-feed filter press. A shaft passes
through the center openings, on which is mounted
plows, one in each chamber. The press is mount-
ed on trunnions and is filled in the vertical posi-
tion. When filled the shaft is rotated and the
plow by moving in a spiral manner peels off the
cake from the chambers. The cake pieces fall
out of the press through the central openings.
The plows do not remove all the cake but leave
a thin layer on the cloths. If it is desired to
remove this layer it may be sluiced off. For
assembling and clothing the press is swung into
the horizontal position. Washing may be done
in the press. Claim is made that this press saves
wear and tear on cloths, saves labor, washes
thoroughly, and is well adapted to arrangements
to carry away cake. This type of press costs
more than the ordinary filter press per unit of
filtering area.
Vallez rotary filter: H. A. VaLLEz. This appa-
ratus consists of a cast-iron cylinder so made that
by removing bolts it can be split lengthwise dis-
closing a hollow shaft on which is mounted the
filter leaves. Filtrate from leaves is drawn away
through center of shaft. When cylinder halves
are bolted together the material to be filtered is
pumped into the interior under pressure, causing
filtrate to issue from shaft. Filter surfaces may
be sluiced off. Extra shafts with leaves may be
kept to facilitate repairs. Leaves are spaced
244, 3 or 6 inches apart. A screw conveyor at
bottom of cylinder removes the solids, which drop
off the leaves when pressure is relieved or a back
air pressure applied. Claim is made that the
rotation of leaves while filtering causes even depth
of solids, indicating uniform washing. Used in
sugar factories.
Centrifugal filters: H. C. Beckman. There
are two classes of centrifugal filters, those in
which the drum is perforated and those in which
the drum is imperforated. The first class is used
largely in sugar factories. Experiments have
been made in which filter paper or cloth is used
over perforations. Has no advantage over ordi-
nary pressure filter and several disadvantages.
Centrifugals of the second class use filter paper
and act in a measure as a self cleaning filter due
to the fact that the solids are discharged from
SCIENCE
[Vou. LV, No. 1417
the discs by centrifugal force. Due to this fact
small areas have large capacity. A disadvantage
is the smallness of size. A ten-inch drum eight
inches high with twenty seven-inch filter plates
operating at 6,000 R.P.M. is the largest size
found commercially practical. Costly liquids like
physiological serums, expensive varnishes, etc., are
handled by centrifugal filters. Maintenance and
upkeep are nominal. Largest size requires about
two H.P. and about four square feet floor space.
Modern leaf type filters: Roprrt C. CAMPBELL.
Description is made of Kelly and Sweetland
leaf filters. Operating instructions for complete
cycle are given. Washing is effected by stopping
formation of cake while there is yet space be-
tween adjacent leaves. Highty-five to 125 per
cent. of the weight of discharged cakes is
required for complete washing. A disc filter of
the continuous suction type in which discs are
mounted on a rotating shaft which allows them
to dip into the mixture to be filtered is described.
Pressure dise filters are suitable for handling
sludges. Containing from less than one per cent.
of suspended solids to the highest per cent. of
solids which can be conveniently pumped and
drained from filter. By use of Kisselguhr col-
loidal or gummy solids may be handled. Suction
disc filters are recommended for sludges contain-
ing over 10 per cent. of comparatively free filter-
ing solids wherein a cake of greater than one
fourth inch thickness may be built in from one
to eight minutes. Average capacity of suction
filters is from 300 to 700 pounds of dry solids
per square foot filter area per 24-hour day. Data
is given regarding size of airand sludge pumps for
pressure or suction dise filters, also water required
for sluicing. When suspended particles are soft
and compressible the plate and frame filter will
produce a drier cake than leaf filters. Claims
leaf filters have lower cloth consumption than
plate and frame filters.

tion of the individual kinds made. (2) General
principles involved—covering the use of the con-

vantages—realized by use of continuous vacuum

and other intermittent types. (7) Limitations
and disadvantages.
Suction filtration: G. D. Dickey. After a brief
outline of the development of suction filtration,
there are taken up the four main points of inter-
est to filtration operators, viz.: Cake formation,
washing, drying, and discharge. Under ‘‘Cake
Formation,’’ there is discussed the various fac-
tors which modify cake building in suction appa-
ratus. Examples are cited as to capacities and
rates of flow of specific materials under varying
conditions, which will illustrate the influence
that these conditions exert over the deposit of
the filter cake. Following the discussion of the
filter cake comes that of washing of the cake,
which of course is dependent upon the formation
of the cake itself, but which can be greatly aided
or hindered by the filter operator. The discus-
sion of cake drying and discharge is also based
primarily upon the cake formation, but allows of
many modifications before obtaining the desired
results. Next there is given a brief description
of the construction and operation of the open
tank type of filter, the continuous rotary filter, and
the continuous rotary hopper dewaterer, together
with the advantages and disadvantages of each
type. A number of lantern slides have been pro-
vided, so that the discussion of the construction
and operation can be illustrated. In conclusion,
there is given specific data as to the handling of
a number of materials by the three types of
apparatus above mentioned.
Industrial filter media: ARTHUR WRIGHT. De-
fines industrial filtration as the separation of a
comparatively large amount of solids from small
volumes of liquid, hence small rates of flow are
permissible and filter cloths used as contrasted
with the municipal filtration where gravel beds
are used and conditions are the opposite. Selec-
tion of filter fabric depends upon whether for
non-corrosive or corrosive liquors. For the latter,
wool, metal, asbestos, stone, etc., is used, while
for the former, cotton is used. Describes various
weaves of cotton and its use. Fabric filtration
should be of surface type, and not bed filtration
where solids enter interior of the medium as in
loose thick duck. Suggest superficial layer of
thin muslin to prevent bed action, permitting
cake to fall off easily. In certain kinds of filters
the cloth porosity must be of definite kind to
permit use of back pressure. Cake adheres more
strongly to unnapped cloth. Discusses drainage
provided under cloths. Precoating cloths should
be used where initial filtrate must be clear.
Shrinkage and stretch of cloth is considered.
SCIENCE
215
Mentions incrustation due to lowering pressure
and suggests action to be taken.
The use of filter-cel for industrial filtration
processes: G. M. Hickey. Filter-Cel, a porous
cellular product, is used as a filter aid, by mixing
a small percentage with the liquor prior to filtra-
tion, overcoming slimes and giving brilliant fil-
trates. In cereal beverage filtration, addition of
one fourth pound of Filter-Cel per barrel insures
complete removal of yeast cells, gives brilliant
product and permits use of modern pressure
filters. In crude and refined vegetable oils it
aids in the removal of foots, soaps and slimes,
giving clearer filtrates that requires less bleach
for refining. When mixed with the bleaching
agent, it increases the capacity of filter and
gives dryer cakes. Apple products and fruit
juices are mechanically clarified by filtration
with small quantities of Filter-Cel. Soap lyes
and fats are clarified using one per cent of
Filter-Cel, improving filtration and the quality of
by-products. Catalytic agents from hydrogena-
tion processes are completely removed by filtering
with Filter-Cel.
Plate and frame filter presses: G. B. Ricz. The
filter press includes a large filter area in a small
floor space, high pressure can be used, the appa-
ratus is simple, unskilled labor only is required
for operation, and repairs are quickly made.
Considers the plate and frame type the best form
of filter press. Describes washing and various
combinations used in filter presses. Filter presses
can be made of various materials, as iron, for
ordinary materials, wood for weak acid liquors,
lead for strong sulphurie acid. For wooden
plates resinous woods are best, as yellow pine;
such wood will stand 25 per cent. cold HCl. Hot
solutions tend to destroy the resin, so for that
purpose maple or oak is best. Describes opera-
tion and storage of wood presses. Discusses filter
plate surfaces, closing gears, and filter cloths.
For most aqueous solutions, cotton cloths are
good, but for strong acid solutions asbestos, wool
or camel’s hair cloth is suitable. Wire cloths
made of monel metal, copper, nickel and bronze
can be used.
The filter press: D. R. Sperry. The filter press
is defined as a press employed for holding to-
gether the component parts of a filter. The com-
‘ponent parts of the filter consist of plates or
plates and frames. The filter press is described
by aid of illustrations. Recessed and flush plate
and frame operation is defined. Filter plates and
frames may be made of various materials to suit
the substance handled. This is also true of filter-
216
bases. A discussion of plate surfaces tends to
show that correct design should be for long wear
of cloth and proper drainage. Also that the con-
tact area of the cloth does not reduce the net
filtering area as might be supposed. The filter
press comprises most filter area per unit of floor
space, can employ high pressures, has low repair
costs, produces the driest cake, is economical in
clothing, ean be operated by cheap labor and is
the most universal and widely used filter appara-
tus to-day. Eleven plant installation views are
given.
A symposium on the chemistry of gases and
fuel was also held with C. H. Stone chairman
and R. S. McBride-secretary. The following four
major subjects were discussed:
(a) Coke-oven problems, discussion to be
opened by W. H. Buiauvett, F. W. Sprerr and
others.
(b) Low temperature carbonization of coal,
discussion to be opened by H. ©. Porrer.
(c) Gas works control, discussion to be opened
by E. C. Unuic, J. R. CAMPBELL and O. A. Mor-
HOUS.
(d) Gas analysis and its applications, discus-
sion to be opened by G. W. Jones, E. R. WEAVER
and A. H. WHITE.
Two new methods for determining light oil in
coke oven gas: ArtHUR L. Davis. The most
accurate and thoroughly reliable method that has
been developed to the present time utilizes acti-
vated carbon as the absorbing medium. Absorp-
tion of the light oil is rapid and the carbon is
very convenient to handle. The absorbed light
oil is removed by distillation of the enriched
carbon with cresol and the subsequent treatment
of the distillate with caustic. The true light oil
recovered, uncontaminated with wash oil, may be
examined and its quality determined. A very
satisfactory means of absorbing light oil is to
pass the gas through a plate and bell tower, lab-
oratory size, using cresol as the absorbing medi-
um. A tower of this type is imperative since
incomplete absorption will be obtained using
other than this general type of equipment when
any liquid absorbent is used. The eresol is
stripped of the light oil and the distillate agi-
tated with caustic. The light oil obtained is true
light oil with no high boiling ends due to the
lower boiling portions of wash oil being present.
Standardizing gas combustion by premixing
portions of air with gas: N. H. GELLER.
A chemically controlled automobile: GnorcE G.
Brown, Jr. The average motor ear wastes twice
SCIENCE
[Vou. LV, No. 1417
as much energy as is converted into useful work.
The thermal efficiency averages not over 15 per
cent. This loss, entirely preventable, is a waste
of a valuable and limited natural resource, petro-
leum. In all industrial combustion problems
increased efficiency can be obtained by returning
as much heat as possible from the exhaust gases
to the combustion zone by preheating the air.
Another factor, known as turbulence, which
results from the velocity of the mixture entering
the cylinder, has an equally noticeable effect
upon the rate of combustion. Repeated tests
have shown that 30, 35, 40 miles per gallon and
even more may be obtained driving at constant
speed along a level highway and burning a lean
hot mixture. It has been found that the two
variables, temperature of air and manifold suc-
tion, are sufficient in themselves to supply all the
automatie control desired. Working along these
lines a carbureter has been designed from a scien-
tific and mathematical standpoint that can be
made to deliver a mixture of any proportions
desired under any conditions. It has been found
possible to obtain 35 to 40 miles per gallon on a
standard Ford touring car with equally quick
acceleration and even more flexibility than could
be obtained with standard equipment giving 20
miles per gallon under the same conditions.

The formation of oxides of nitrogen im the
slow combustion and explosion methods in gas
analysis: G. W. JoNES and W. L. Parker. Pro-
cedure and results of investigation are given
showing the amounts of oxides of nitrogen
formed when gases are analyzed by the slow
combustion and explosion method. The following
conclusions were obtained: The production of
oxides of nitrogen by the slow combustion method
when the time of burning is not more than three
minutes and the wire heated not greater than a
bright yellow is within the experimental error in
routine gas analysis. Under the above conditions
not more than .003 e.c. of oxides of nitrogen
- tion.
FuBrvary 24, 1922]
were produced by the explosion method when air
was used as the oxygen supply. When mixtures
of air and oxygen were used as the oxygen supply
in the explosion method appreciable quantities of
oxides of nitrogen were produced which are too
large to be disregarded in gas analysis. The
method used for determining the quantity of
oxides of nitrogen produced was a modification of
the di-phenol sulphonic acid method as used in
water analysis.
The present status of methods used for fuel
gas analysis: G. W. Jones. The constituents
present and difficulties encountered in the accu-
rate analysis of fuel gases are given. The meth-
ods used at the present time, considerations
which must be taken into account in choosing a
particular method, the comparative accuracy of
the different methods and debatable points which
require further consideration are discussed.
Electric heat for thermal processes: HE. F.
COLLINS.
Humidity equilibria of various common mate-
rials: Ropert E. Wiuson. A knowledge of the
equilibrium amount of moisture held by various
materials as a function of the relative humidity
of the air is very important for a variety of
purposes. The author presents determinations by
a method previously described in the Journal, of
the humidity equilibria of the following mate-
rials: cotton, linen, paper, jute, hemp, viscose
silk, cellulose nitrate silk, cellulose acetate silk,
tubber, leather, feathers, catgut, tobacco, crack-
ers, bread, macaroni, ete.; and includes data
gathered from various sources on other materials,
such as wool, silk, paper half-stuffs, timber, flour,
ete.
The frictional resistance to the flow of viscous
liquids through elbows: Robert E. Witson, WIL-
LIAM H. McApAMs and M. Srurzer. The fric-
tional resistance to the flow of liquids through
elbows has been the subject of a considerable
number of scattered experiments, but the results
are seldom expressed on any uniform basis and
in many eases the methods of measurement were
faulty. Furthermore, there is practically no data
on the frictional resistance to flow through elbows
for very heavy oils flowing in straight line mo-
The authors present a series of data cover-
ing the whole range, from highly viscous oils to
water, and show that, while the customary rule
of assuming an elbow to be equivalent to thirty
or forty pipe diameters’ length of straight pipe
holds very well over the whole region of turbulent
flow, the resulting correction is far too high in
the region of viscous flow, dropping to as low as
SCIENCE
217
two or three diameters for very viscous liquids
in small pipes.
A fermentation process for the production of
acetone, alcohol and volatile acids from corn cobs:
W. H. Prererson and E. B. Frep. Corn cobs are
a possible raw material for the production of
acetone, ethyl alcohol, formic acid and acetic
acid. These products are obtained by fermenting
a sirup which is made from corn cobs by
hydrolysis with dilute sulfuric acid and contains
chiefly xylose. This crude xylose sirup is fer-
mented by Bacillus acetoethylicum under the
proper conditions of nitrogen, and phosphate
supply and hydrogen ion reaction. A continuous
fermentation is maintained by filling the con-
tainer with cinders to which the bacteria may
attach themselves. The fermented solution is
removed and a new sugar solution added without
disturbing the bacteria. Under these conditions
the fermentation is rapid and vigorous. The
yield of products is 2.7 Ibs. of acetone, 6.8 Ibs. of
alcohol and 3.4 Ibs. of acid per 100 lbs. of corn
cobs.
A new method of preparing sulphuric acid:
P. C. Hansever. Instead of oxidizing SO,
with the oxide of nitrogen, selenium dioxide
is used according to the equation: 280, + H,0
ae H,SeO, = 2H,SO, + Se. The selenium is
filtered and reoxidized. A 50 per cent sulphuric
acid free of selenium can thus be obtained
without pressure. Anode slimes and other im-
pure selenium sources can be used for the source
of selenium, as roasting the same will yield an
oxide sufficiently pure for the above reaction.
Corrosion under oil films and the protective
action of certain colloidal solutions: Witpert J.
Hurr. An investigation by the writer in the
research laboratories of the Bureau of Mines on
the subject of corrosion beneath oil films caused
by water soluble salts from perspiration residues,
sea sprays, and certain manufacturing operations.
Preliminary treatment with water, followed by a
suitable emulsion, and finally by oil is recom-
mended for inaccessible surfaces. Experiments
are given to show the valuable anti-corrosive
property of certain soap emulsions, and some of
the conditions under which this protective prop-
erty fails. The mechanism of the corrosion and
protection is discussed briefly.
On the dehydration of tar and other organic
emulsions: WitBrrT J. Hurr. A note discussing
some of the methods for the dehydration of tar
and similar emulsions, pointing out a few ad-
vantages and disadvantages of each, together
with a description of a method suggested by the
218
author and now used in the laboratories of The
Koppers Company. The tar is simultaneously
heated from above and cooled by a jacket of
liquid water about and below. The jacket water
is allowed to fall by evaporation, gradually
bringing more and more tar into the heated zone.
The manipulation is so simple the author finds it
difficult to believe that the method has not been
used before, but if so is unaware of such use.
The method permits the simultaneous approxi-
mate determination of light oil and water,
requires no new apparatus and practically no
attention, and handles efficiently very stiff tars
and tars of high water content.
The arc rupture of liquid dielectrics: C. J.
RopMAN. Various organic liquid dielectries were
subjected to high frequency arcing. Finely
divided, highly non-conducting amorphous carbon,
saturated and unsaturated hydrocarbons lower in
the series, and a number of gases were obtained.
These gases consisted chiefly of hydrogen and
unsaturates with small amounts of carbon mon-
oxide, carbon dioxide, methane and nitrogen.
With an increase in molecular weight a slight
decrease in gas evolution per kilowatt seconds of
are rupture was noted. With an increase of
halogenation a corresponding decrease in gas
evolution per kilowatt seconds are rupture is
noted. Paraffine oils give approximately 60 cc.
gas per kilowatt seconds. The liquid dielectrics
are apparently broken down by a temperature
pressure effect of very short duration, rather
than by sympathetic vibration and rearrangement
of the compounds by high frequency alone. Direct
application of this data is found in the use of
compounded liquid dielectrics for transformers,
circuit breakers and fuses.
The effects of waterproofing materials upon
the tensile strength of cotton yarn: H. P. Hot-
MAN and T. D. JARRELL. Two sizes of cotton
yarn used in the manufacture of high grade
cotton ducks, after treatment with numerous
waterproofing materials including commercial
preparations, individual substances and formulas
developed in the laboratory, were exposed to the
weather for one year to show the effects on ten-
sile strength. The tensile strength of the treated
yarn after one year’s exposure was in most cases
greater than the strength of the untreated yarn
after one year’s exposure.

The nature of acid mine water from coal mines
and the determination of acidity: W. A. SELvig
and W. C. Ratcuirr. Water from coal mines is
usually decidedly acid in character containing
free sulphuric acid and ferrous, ferric and alum-
inum sulphates in addition to sulphates of cal-
cium, magnesium, sodium and potassium together
with silica and usually some chlorides. On stand-
ing, dilution, aeration or warming insoluble iron
compounds tend to precipitate. The direct titra-
tion of free sulphuric acid of mine water with
standard alkali solutions in the presence of
methyl orange gives results much too high.
Methods of accurate determination of contents of
mine water are given.
Tests of the iodine pentoxide indicator for car-
bon monoxide: 8S. H. Karz and J. J. BLOOMFIELD.
The iodine pentoxide or ‘‘hoolamite’’ indicator
for carbon monoxide is a small, rugged, portable
instrument for quickly and easily indicating the
presence of carbon monoxide and estimating its
concentration. Commericial instruments were
tested for sensitivity and accuracy. Results
showed that the instrument gives positively indi-
cations with .07 per cent. or more carbon mon-
oxide in air. With .15 per cent. carbon monoxide
in air, determinations ranged from .10 to .23 per
cent. with an average of .16. With higher con-
centrations, the variations were proportionally
about the same. Fresh activated charcoal re-
moves the following gases that tend to give inter-
ference: acetylene, ammonia, benzene, ether,
ethylene, gasoline, hydrogen chloride, hydrogen
sulphide, natural gas containing members higher
than methane, and water. The following gases
do not interfere: carbon dioxide, carbon tetra-
chloride, chlorine, methane, nitrogen peroxide,
phosgene, and sulfur dioxide. Determinations
are made in less than one minute and no skill is

ATOMIC NUCLEP
I. INTRODUCTION
THE conception that atoms consisted of cen-
tral positively charged nuclei of small dimen-
sions surrounded by one or more systems of
electrons whose aggregate charge of negative
electricity exactly neutralized the nuclear posi-
tive charge, arose in an attempt by Rutherford?
to explain the large angle scattering of « rays
obtained when these traversed thin foils or
sheets of various metals.
To account for the results obtained it was
found necessary to assume that the positively
charged nucleus contained nearly all the mass
of an atom and that the dimensions of the
nucleus were very small compared with the
ordinarily accepted magnitude of the diameter
of the atom.
On this view the electric field close to the
nucleus was very intense and therefore suffi-
cient to deflect « particles which in traversing
sheets of metal happened to pass close to
nuclei.
Assuming the electric field of nuclei to be
central and to follow the inverse square law,
Rutherford showed that an « particle pro-
jected so as to pass close to the nucleus of an
atom would describe a hyperbolic orbit about
the nucleus and that the magnitude of the
deflection impressed upon it was determined
by the closeness of its approach to the nucleus.
(a) The electric charge on nuclei.
On this theory Rutherford showed by deduc-
tions made from observations on the single
encounter large angle scattering of « rays that
the resultant charge on the nucleus was about
72 A e where A is the atomic weight of the

scattering element and e is the fundamental
unit of electric charge. Hlaborate experiments
by Geiger and Marsden® on the scattering of
#% rays confirmed this view. The validity of
the theory was also established in a convincing
manner by C. G. Darwin* who made a thorough
mathematical investigation of the deflexions
which could ensue from an intimate encounter
between an alpha particle in motion and a
nucleus. In this investigation he showed that
the results of the scattering experiments of
Geiger and Marsden could not be reconciled
with any law of central force except that of
the inverse square.
In another entirely different field of investi-
gation, namely, that of the scattering of X rays
by lght elements, Barkla® had shown in 1911
that the number of electrons in an atom which
took part in the scattering of the X rays was
equal to about one half of the atomic weight
of the element.
Both lines of investigation therefore led to
the view that the charge on the nucleus of an
atom was given by % A e and that the number
of electrons in an atom surrounding the nucleus
was % A. It was the experiments on the scat-
tering of « rays, however, which led to the
view that the positively charged portions of
atoms were nuclear in character with dimen-
sions small compared with those of the atoms
themselves, and that by far the greater part of
the mass of the atoms was concentrated in the
nucleus.
(b) Nuclear charge and atomic number.
In 1913 Van den Broeck® put forward the
suggestion that the scattering of « particles
was not inconsistent with the view that the
charge on the nucleus of an atom was equal to
Ne where N is the atomic number of the atom
of the element concerned, 7. e., the number of
the element when the elements are arranged in
order of increasing atomic weight. A refer-
ence to a table of atomic weights will show
that N is approximately equal to % A. The

[Von. LV, No. 1418
importance of this suggestion was soon made
evident by the remarkable work of Moseley’
on X ray spectra which followed in 1913 and
in 1914. In this work Moseley showed that
the frequencies of the vibrations of correspond-
ing lines in the X ray spectra of the elements
depended on the squares of numbers which
varied by unity with the successive elements.
This relation, it was seen, could be readily
explained by assuming that the nuclear charge
of an atom varied by unity in passing from an
atom of one element to that of another, and by
assuming that the nuclear charge was given
numerically by N, the atomic number.
The importance of Moseley’s work was
enhanced when it was seen that it gave us a
new method of regarding the periodic classi-
fication of the elements based on the assump-
tion that the atomic number or its equivalent,
the nuclear charge, was of more fundamental
importance than the atomic weight. As a
result of Moseley’s work it became possible
not only to fix definitely the number of pos-
sible elements and the position of undeter-
mined elements, but also to show that the
properties of an atom were defined by a num-
ber which varied by unity in successive
elements.
In Moseley’s work the frequency of vibration
of corresponding lines in the K ray spectra of
the elements was not found to be exactly pro-
portional to N? where N is the atomic number
but to (N—a)? where a was a constant which
had different values depending on whether the
IX or L series of characteristic rays was
measured.
The investigations of Bohr® on the origin of
radiations emitted by atoms are entirely in
keeping with the assumptions that the nuclear
charge is given by Ne, for he has shown that
the frequency formula for X ray spectral lines
must inelude a term (N —a)? with “a” having
values approximately equal to those found by
Moseley. In Bohr’s investigation he showed
that X rays originated in disturbances given
to certain classes of extra nuclear electrons
and that the quantity “a” represented a modifi-

cation of the electric field of the nucleus by
the electric fields of the extra nuclear electrons
within the atom.
II. Own tHe Structure or Atoms
Through the advances made by a study of
the scattering of « rays and of X rays the
attack on the problem of the structure of
atoms and the origin of radiations naturally
proceeded upon two well-defined lines, namely:
1. The investigation of the constitution and
properties of the nucleus, and
2. The investigation of the configuration
and modes of vibration of extra nuclear elec-
trons in atoms.
In pursuing this attack it has been assumed,
with very good warrant, that the positive elec-
trie charges on nuclei are given by Ne where
N is the atomie number of the element con-
cerned, and that the number of extra nuclear
electrons in an atom is N. For example, the
number of extra nuclear electrons in various
atoms is taken to be as follows: Hydrogen 1,
helium 2, lithium 3, carbon 6, fluorine 9, neon
10, sodium 11, chlorine 17, argon 18, potas-
sium 19, ete.
III. Postrive Ray ANALYSIS
This method of analysis was devised by Sir
J. J. Thomson® and consisted in projecting
successively through an electric and a magnetic
field positively charged atoms or molecules,
i. e., those from which one or more extra
nuclear electrons had been detached. By this
means he was able to show that positive atom
ions can be obtained with one, two, three, and,
in the case of mercury, with eight positive
elemental charges.
Among other results he has been able to
show that such compounds as CH, CH, and
CH, can exist with a recognisable though
transitory existence. He has also shown that
a substance having the molecular formula H,
and bearing a single positive elemental charge
can be obtained from various sources, a result
which has been confirmed by Dempster, who
showed that this molecular aggregate can be
obtained with a transitory existence when an
9J. J. Thomson: Rays of positive electricity.
SCIENCE 221
electric charge is passed through hydrogen.
Perhaps the most notable discovery made by
Thomson, however, was that neon existed in
two forms with identical chemical properties,
but with different integral atomie weights,
namely, 20 and 22.
This discovery was of prime importance for
it poimted to the probability of the general
applicability of the principle which had been
already found by Soddy and others to hold
with the radioactive elements, namely, that the
atoms of elements consist of csotopes, i. e.,
that we have atoms of an element with identical
chemical properties, but with different atomic
masses. This discovery also offered an explan-
ation of the non-integral values found by
chemical analysis for the atomic weights of
many of the elements. If it turned out, assum-
ing the atomic weight of oxygen to*be 16, that
the atomic weights of the isotopes of an ele-
ment were integers, then the non-integral value
found by chemical analysis for the atomic
weight of an element would result from the
element existing as a mixture of its isotopes.
IV. Isoroprs
Aston,'® Dempster,'t and later G. P. Thom-
son’? have recently greatly improved Sir J. J.
Thomson’s methods of positive ray analysis
with the result that they have been able to
separate many of the elements of non-integral
atomie weight such as chlorine, magnesium,
argon and mereury into isotopes, each of which
has an integral value for its mass. Chlorine, for
example, has an atomic weight of 35.5 and
can be separated by the positive ray method
into an isotope of weight 35, and into one of
weight 37. The validity of this result has
been confirmed by Harkins,'!* who succeeded

into two portions with different densities.
Mercury, too, has been found by positive ray
analysis to consist of a number of isotopes,
probably six, with integral atomic weights
197-200, 202, 204. As a confirmation of this
result Bronsted and Hevesy* have shown that
it is possible by fractional distillation to sep-
arate mercury into two parts with different
densities.

V. Discussion oF IsoToPEs
A glance at the results in Table I suggests a
few observations.
(a) Isobares and radioactivity.
It is interesting to note that while iodine
with an atomie weight 126.92 has but one
isotope, 127, bromine with an atomic weight
79.92 has two, 79 and 81. Had it turned out
that bromine consisted of but one isotope with
weight 80 we should have had an example of
an isobare, that is, an atom of one element
with an atomic weight the same as that of an
atom of a second element. It will be seen that
one of the isotopes of krypton has an atomic
weight 80.
It is also of interest to point out, as Harkins
has done, that with magnesium having 3 iso-
topes and chlorine 2 it is possible to have nine
isotopic forms of MgCl,. As mercury has six
isotopes there would follow the possibility of
having 63 isotopic forms of Hg,Cl,. Similar
considerations would apply in regard to other
elements.
G. P. Thomson has recently found that
strontium consists of two isotopes of weight
85 and 87. He failed however to find one of
weight 88 or any higher number the necessity
for which the atomic weight of strontium,
87.63, would seem to demand. As rubidium
was shown to have isotopes of weight 87 and
85 we have in strontium and rubidium an
example of isobaric isotopes, 7. e., the atoms of
these two elements are identical in mass. As
the nuclear charge of rubidium is 37e while
that of strontium is 38e, it follows that the
nuclei of rubidium atoms differ from those of
strontium atoms only by the inclusion of one
electron. This may possibly afford an explana-
tion of the radioactivity which rubidium and
its salts are known to exhibit. It has been
shown that rubidium emits a soft radiation of
beta particles, and since it is now generally
agreed that radioactivity is a property of
nuclei, it would follow that by the emission of
beta rays, rubidium atomic nuclei are being
transmuted into those of strontium. One
should expect to find, then, strontium asso-
ciated with the sources of rubidium.

As potassium is also known to emit a radia-
tion of beta particles we should expect the
nuclei of atoms of potassium to be transmuted
thereby into nuclei of calcium of the same
weight, 7. e., we should expect to find that
calcium consisted of two isotopes isobaric
with those of potassium and therefore of
weight 39 and 41. As regards this point the
only evidence we have available is that fur-
nished by the experiments of G. P. Thomson,
who states that he found an isotope for calcium
at 40 but with the magnetic field at his dis-
posal it was impossible to separate lines even
two units apart if such had existed for eal-
cium. Thomson states, however, that it is cer-
tain that one or more isotopes of the weights,
39, 40, and 41 were present in his experiments.
In some preliminary experiments made by
Dempster an isotope of calcium was found at
or near 40. He states, however, that the possi-
bility of one of weight 39 is not excluded by
his results. It will be interesting to see
whether future experiments show that calcium
has two isotopes of weight 39 and 41. Some
additional evidence on this point might be
gained by investigating the association of eal-
cium with primary sources of potassium and
its salts.
In this connection it is of interest to point
out that lithium, sodium and cesium have not
been found to be radioactive. Moreover
neither lithium and beryllium nor sodium and
magnesium have any isotopes in common.
Cesium has been found to have but one isotope
of weight 133 and although the isotopes of
barium have not yet been investigated it would
appear to be highly probable that, since the
atomic weight of this element is 137.37, it will
be found not to have any isotope isobaric with
that of exsium.
(b) Isotopes of cadmium.
Since the atomic weight of cadmium is 112.4
it will be seen that it will likely be found to
have a number of isotopes, especially since
zine has been shown to have four and mereury
slx.
(c) Atomic weight and atomic number.
It will be noted that, with the possible excep-
tion of KX*° and the doubtful Cl°° Table I does
not show any other examples of isobares. There
is a remarkable intermingling of the atomic
weights and it is particularly noticeable in the
case of ten consecutive integers representing
the isotopes of bromine, krypton, and rubidium
—Kr 78, Br 79, Kr 80, Br 81, Kr 82, Kr 84,
Rb 85, Ky 86, Rb 87. This result makes it
224
clear that the exact order of the chemically
determined atomic weights is of little signifi-
cance and that the anomalies such as argon
and potassium and possibly too of tellurium
and iodine as well as nickel and cobalt are
merely due to the unequal relative proportions
of their constituent isotopes.
From a consideration of the total abundance
of various elements Harkins!’ pointed out that
for the great majority of possible configura-
tions it would probably be found that even
atomic weight was associated with even atomic
number and odd with odd. The results given
in Table I, it will be seen, support this view.
Of the halogens (odd atomic numbers) all six
isotopes are odd. Of the alkali metals (odd
atomic numbers) seven istopes are odd and
only one even. On the other hand, of the iso-
topes of the inactive gases (even atomic num-
bers) fifteen are even and but three odd. This
means that in the nuclei of most types of atom
the number of electrons is an even number.
(d) The spectra of isotopes.
In an attempt made by Harkins, Aronberg
and Gale'® to see whether any method of dis-
tinguishing between the isotopes of an element
could be obtained from a study of their spectra
it was found that the wavelength of the line

greater than that predicted on the hasis of
Bohr’s Theory of Radiation. Loomis!® also

lites which Imes?® found beside each line of

average wavelength of 16.4 A.U., longer than
the lines which they accompany. These satel-
lites Loomis has shown can be accounted for by
assuming them to be due to the heavier of the
isotopes of chlorine of weights 35 and 37. On

will be seen is in good agreement with observa-
tions of Imes.
(e) Structure of atomic nuclei.
By far the most important conelusion which
can be drawn from the results recorded in
Table I is that, with the exception of hydrogen,
the weights of the isotopes of all the elements
measured and, therefore almost certainly of all
elements, are whole numbers, within the
accuracy of the experiments—namely, about
one part in a thousand. This result carries
with it the possibility of greatly simplifying
our ideas of mass. The original hypothesis of
Prout, put forward in 1815, that all atoms
were themselves built of atoms of protyle, a
hypothetical element which he tried to identify
with hydrogen, has been established on a new
basis with the modification that the primordial
atoms are of two kinds—atoms of positive and
negative electricity. The unit of negative elec-
tricity, the electron, we have long been familiar
with, but the unit of positive electricity, which
also appears to be the real unit of mass, has
remained unidentified experimentally until now
as the positive nucleus of the atom of hydro-
gen. To this unit of mass and of positive elec-
tricity the name of “proton” has been given.
This profound modification of our views of
the nature of mass has been very clearly set
forth by Aston. The Rutherford atom
whether in Bohr’s or Langmuir’s development
of it consists essentially of a positively charged
central nucleus around which are set planetary
electrons at distances which are great compared
with the dimensions of the nucleus itself. As
has been stated the chemical properties of an
element depend solely upon the atomic number
which is the charge on its nucleus expressed
in terms of the unit charge “e.” A neutral
atom of an element of atomic number N has a
nucleus consisting of K-+N protons and K
electrons and around this nucleus are set N
electrons. The weight of an electron on the
seale we are using is 0.0005 so that it may be
neglected. The weight of the atom will there-
fore be IX-+-N so that if no restrictions are
Marcu 3, 1922]
placed on the value of K any number of iso-
topes is possible.
The first restriction is that excepting in the
case of hydrogen K ean never be less than N
for the atomic weight of an element is always
found to be equal to or greater than twice its
atomic number.
The upper values of K also seem to be lim-
ited, for so far no two isotopes of the same
element have been found differing by more
than 10 per cent. of its mean atomic weight,
the greatest difference is eight units in the
case of krypton. The actual occurrence of
isotopes does not seem to follow any law at
present obvious, though their number is prob-
ably limited by some condition of stability.
Protons and electrons may therefore be re-
garded as the bricks out of which atoms have
been constructed. An atom of atomic weight
m is turned into one of atomic weight m-—+ 1
by the addition of a proton plus an electron.
If both enter the nucleus the new element will
be an isotope of the old one, for the nuclear
charge has not been altered. On the other
hand, if the proton alone enters the nucleus
and the electron remains outside, an element of
next higher atomic number will be formed.
If both of these new configurations are pos-
sible they will represent elements of the same
atomic weight but with different chemical
properties. Such elements we have pointed
out above are called isobares, and are already
known to exist among the radioactive elements.
(See Table IT).
The element hydrogen, it will be noted, is
unique in that its nucleus weight, 1.008, ex-
hibits a departure from the rule of integers
followed by the isotopes of all the other
elements investigated. It will be noted, how-
ever, that it is the only atom in which the
nucleus is not composed of protons and elec-
trons closely packed together. It can be shown
that with close packing of protons and elec-
trons there must follow a reduction in effective
mass, and that when four protons and two
electrons are closely packed together as they
must be in alpha particles, the nuclei of helium
atoms, the resultant effective mass must be
somewhat less than four times that of the
hydrogen nucleus.

VI. THe Diwensions or Atomic NUCLEI,
THEIR ELECTRIC CHARGES AND
Fisips or Force
While phenomena connected with the seat-
tering of « rays have led to such profound mod-
ifieations in our views of atomic structure, it is
of interest to note that through the agency of
these same «@ rays we are likely to make still
further advances in the problem of determin-
ing the ultimate structure of matter. Through
the attacks now being rigorously pressed by
Rutherford and his associates, the structure of
the nuclei of atoms is slowly but steadily being
revealed. Through the bombardment of atomic
nuclei by « rays it has been found that the
electric charges on atomic nuclei can be meas-
ured with a high degree of precision, estimates
of the diameters of nuclei can be made, the
field of electric force about a nucleus can be
examined, and the structure of the nucleus
itself can be broken down.
(a) Nuclear charges.
In his early experiments, Rutherford had
shown from the experiments of Geiger and
Marsden on the scattering of « rays that the
charge on the nuclei of atoms of gold was
within 20 per cent. equal to 100 e. More
recently Chadwick?° has shown by the use of
direct and more refined methods that the
charges on the nuclei of three types of atoms,
namely, those of platinum, silver and copper,
have the value of 77.4e, 46.3e and 39.3e respec-
tively. As the atomic numbers of these ele-
ments are 78, 47 and 39, it will be seen that
these results strongly confirm the view put
forward by Rutherford as a result of the
experiments of Moseley and others, which indi-
cate that the nuclear charge is equal to Ne, N
being the atomie number of the element.
(b) Nuclear dimensions and nuclear electric
fields of force.
As mentioned above, Rutherford has shown
by experiments on the scattering of « rays that
the dimensions of atomic nuclei must be ex-
ceedingly small. For example, when high
speed « particles collided with atoms of gold
they were found to be turned back in their
path at a distance of 3 10—1 em. between
20 Chadwick, Phil. Mag., Dec., 1920, p. 734.
226
the centers of the « particles and those of the
nuclei of the atoms of gold bombarded. This
would go to show that in the case of the
nucleus of an atom of gold, its radius is prob-
ably not greater than 3 X10—8 em. Further
evidence in this direction has recently been
adduced by Chadwick who found that the dis-
tance of approach of high speed « particles
to the nuclei of platinum atoms was about
7 X10—? em. and of low speed « particles
about 14 X 10-2 em.
In order to account for the velocity given
to hydrogen atoms by collision with « particles,
Rutherford caleulated that the centers of the
nuclei of helium and hydrogen must approach
within a distance of 1.7 X 10-18 ems. of each
other, assuming the law of repulsion to be that
of the inverse square.
But the recoil phenomena of hydrogen atoms
bombarded by « particles cannot be completely
accounted for by assuming an inverse square
law to hold for all distances between the
centers of the « particle and the. hydrogen
nucleus. Rutherford suggested that roughly
they could be explained by taking the « par-
ticle to be the equivalent of a plate of radius
3 x 10—” em. and assuming that as long as
the « particle did not approach within this
distanee of the hydrogen nucleus, the ordinary
inverse square law of repulsion held. If, how-
ever, the « particle did approach within this
distance of the hydrogen nucleus a collision
ensued which swept the latter straight for-
wards.
An attempt was made by Darwin?! to work
out the collision relations for all possible
models of the « particle for which the electric
fields would give integrable orbits. As a basis
for this work he assumed the « particle to
consist of 4 protons and 2 electrons, and found
that a square nucleus in which the pretons were
arranged at the four corners of the square and
the two electrons together at the center of the
square, would give a field of force very similar
to that of a bipole with collision relations
roughly similar to those deduced from Ruther-
ford’s experiments.

1921.
SCIENCE
[Vou. LV, No. 1418
This model has been put to the test by Chad-
wick and Bieler?? and by MeAuley2* in a new
series of investigations on collisions between
particles and hydrogen nuclei and has been
found to be not entively satisfactory. In these
experiments the earlier observations made by
Rutherford were confirmed, namely, that «
particles and hydrogen nuclei in collision do
not behave as point charges. Not only is the
angular distribution of the projected hydrogen
nuclei ditierent, but the numbers projected
at small angles are for « particles of high
velocity many times greater than those for
point nuclei. For example, the observed num-
ber of hydrogen nuclei projected within 30°
ot the direction of incident « rays of range 8.2
em. is more than 100 times as great as the
theoretical number. The number projected
within the same angle by « rays of range 4.3
em. is 15 times the theoretical number. Also
the observed variation of the numbers of. pro-
jected hydrogen nuclei with velocity of the «
particle is in the opposite direction from that
given by the point theory. For example, «
rays of range 8.2 em. project within an angle
of 30° nearly 3. times as many hydrogen
nuclei as % rays of range 4.3 em. On the basis
of the point charge theory the « rays of 4.3
em. range should give nearly 3 times as many
as the 8.2 em. @ rays. It would appear, ac-
cording to Chadwick and Bieler, that as a first
approximation the « particle behaves in eolli-
sion with a hydrogen nucleus as a body with
properties intermediate between an _ elastic
sphere and an elastic plate, and more like an
elastic oblate spheroid of semi axes about
8X 10-8 em. and 4 X 10-3 em., respectively,
moving in the direction of its minor axis. On
this view a hydrogen nucleus projected towards
an « particle would move under the ordinary
electrostatic forces governed by the inverse
square law until it reached a spheroidal sur-
face of the above dimensions. Here it would
encounter an extremely powerful field of force
and recoil as from a hard elastic body. The
deductions made by Chadwick and Bieler are

interesting in that they emphasize the view
that in dealing with collisions between « par-
ticles and hydrogen nuclei one must recognize
that the inverse square law of vepulsion ceases
to hold in the immediate neighborhood of the
electric charges carried by these nuclei. What
the law of variation of the electrie force is
very close to an electric charge such as we have
in an o particle can not as yet be deduced
from the experimental evidence available. It
is clear, however, that the electric forces in
this region are of great intensity.
It is of interest to note that Chadwick and
Bieler have pointed out that thei experiments
provide the only direct evidence we have as
to the size of electrons. Assuming an @ par-
ticle to consist of 4 protons and 2 nuclei it can
be seen that the dimensions of the model ot
the « particle which their experiments have led
them to put forward require that the radius
of an electron cannot be greater than about
4x10—-8 em. Hitherto the only information
we have had available as to the dimensions of
the electron has been that obtained by calceula-
tions based on the assumption that its mass is
wholly electromagnetic. Such calculations
have given the value 2X10—2 em. for its
diameter. While it is clear that an inverse
square law of foree does not hold in the
region extremely close to a nucleus, the experi-
ments of Geiger and Marsden on the angular
seattering of alpha particles by gold atoms
between 5° and 150° show that it does hold
very closely for distance, between 3.1 x 10—!2
em. and 386 X10—-!2 em. from the center of
nuclei such as those of gold atoms. In this
connection it will be recalled that the agree-
ment between the experimental
of the X-ray KK series spectra and the the-
oretical values of Debye** and WKyoo7? shows
that the inverse square law still holds at the IK
ring of electrons. In the ease of platinum the
radius of the K-ving is about 10-19 em. Thus
measured from any point in the region between
x 10-2 em. and 10-9 em. from the nucleus
of a heavy atom like gold or platinum, the
nuclear charge is equal to the atomic number

and the law of force is the inverse square. We
may therefore conclude that no electrons are
present in the region between the nucleus and
the I< ring.
This result is of special importance in eon-
nection with observations recently made by
Barkla’® and White and confirmed to a certain
extent by Crowther,?* which point to the possi
bility of stimulating atoms to emit radiations
of wavelengths shorter than those of any of

(a) H. particles.
The study of isotopes which we have briefly
outlined above has led to very definite views
regarding the structure of atomic nuclei. It is
clear that all nuclei must be made up of
protons and electrons held together by intense
fields of foree. Direct experimental evidence
in support of this view has recently been
brought forward by Rutherford? and _ those

swift alpha particles ave made to pass through

to pass through hydrogen the maximum range
obtainable for the recoil of hydrogen nuclei
is never greater than the equivalent of 29 cm.
in air. This makes it clear that the recoil of
H particles or protons obtained with nitrogen
can not arise from the presence of hydrogen
as an impurity in the gas. The H particles
must therefore originate in the nuclei of the
nitrogen atoms which must therefore suffer
disintegration under the intense bombardment
of the alpha rays. Results similar to those
obtained with nitrogen have been obtained
with other elements that have been examined
but it is of interest to note that it is only those
elements whose atomic mass is given by
4n+2 or 4n-+3 where n is a whole number
that give rise to H. particles. Elements of
mass 4n like carbon, oxygen and sulphur show
no effect. In Table III the results obtained
so far are summarized.

(b) Ranges of H. particles.
With aluminium it will be seen the range of
the expelled protons is more than twice as
great as for those liberated from hitrogen.
The number of H particles expelled from
the nuclei of the atoms of different elements is
found to vary greatly with the speed of the
impinging alpha rays. When alpha particles
from thorium C which have a range of 8.2 em.
in air are used the H particles are relatively
numerous. With « particles having a 7 em.
range in air, 7. e., those emitted by Ra.C, the
number of H particles ejected is considerably
smaller. With alpha rays of range 5 cm. in
air the number is exceedingly small. With
aluminium no HH particles appear to be re-
leased by alpha particles of range less than
5 em.
SCIENCE
[Vou. LV, No, 1418
(c) H particle satellites: backward recoil.
In experiments with aluminium foils bom-
barded by alpha rays it was found that the
direction of escape of the H particles was to a
large extent independent of the direction of the
impinging alpha particles. Nearly as many
were expelled in the backward as in the for-
ward direction. The maximum range for H
particles ejected in the backward direction
was, however, found to be less than that of H
particles projected forwards. In the case of
the former the maximum range was 67 em.
while with the latter it was 90 em. air equiva-
lent.
In order to explain the ejection of H parti-
cles in all directions Rutherford and Chadwick
haye put forward a simple explanation. They
suppose that in such an atom as that of nitro-
gen the main nucleus has a mass 12 and that it
has two H particles moving in an orbit round
and close to it. The manner in which the eolli-
sions are supposed to occur is shown in Fig. I.

If the collision oceurs as in A the H particle
is driven in the forward direction of the alpha
particle and away from the nucleus; if, as in
B, the H particle is driven towards the nucleus;
it describes an orbit close to the latter and
escapes in a backward direction. The differ-
ence in the velocity of the H particles in the
forward and backward directions is probably
due to the fact that the main nucleus has been
set in motion, in the direction of the alpha
particle, before the close collision with the H
particle oceurs. On this view the relative
velocity of the H particle and the residual
nucleus is the same whether the H particle
escapes in the backward or forward direction;
but the actual velocity in the backward direc-
tion is less.
(d) Attraction between positive charges.
Marcu 3, 1922]
This explanation, it will be noted, implicitly
assumes that positively charged bodies attract
one another at the very small distances involved
in the close collisions between alpha particles
and atomic nuclei. Rutherford and Chadwick
have pointed out that in order that the ecollid-
ing alpha particle may communicate much of
its momentum to an H particle satellite the
latter must be held by strong forces to the
nucleus. If, however, the H satellite is very
close to the nucleus the alpha particle may
have to communicate a considerable fraction of
its momentum to the central nucleus, and the
velocity of escape of the H satellite is cor-
respondingly reduced. This for example may
be the explanation why the. alpha particles
from aluminium are ejected at higher speeds
than those from phosphorus-of higher nuclear
charge. In phosphorus the H satellites may
move so close to the nucleus that the alpha
particle is able to give a smaller share of its
momentum to the H satellite than in the case
of the more distant satellite of aluminium.
(e) Close satellites.
So far no H particles have been obtained
with elements heavier than phosphorus. The
failure to obtain them with such elements may
be due to the fact that the H atoms either move
very close to the central nucleus or are incor-
porated in it.
(f) Disruption potential.
The theory of nuclear disintegration put for-
ward would seem to demand a definite disrup-
tion potential for nuclei having one or more
H satellites revolving about them. The experi-
ments with aluminium support this view as
no H particles are released from aluminium
nuclei by « particles of range in air less than
5 em. The disruption potential for the nuclei
of aluminium atoms, i. e., the potential differ-
ence required to communicate the same energy
to an electron as is possessed by the « particle
is of the order of six million volts. The cor-
responding potential to liberate an electron
from the K or inner ring of electrons, of the
atoms of aluminium is only about 2,200 volts.
By a simple ealeulation it can be shown that
the results obtained by Rutherford indicate
that by operating at six million volts one could
with the daily expenditure of 600,000 H.P.
SCIENCE
229
disintegrate the nuclei of three cubic feet of
nitrogen and obtain thereby not only the re-
covery of the 600,000 H.P. but also approxi-
mately 80,000 H.P. in addition.
(g) Atomic weight of nitrogen.
If the view put forward is correct that the
H particles are satellites of the central or main
nucleus the mass of the H satellite,—since it is
not in the “closely packed” condition,—should
not be very different from that of a free H
nucleus. Assuming that the nitrogen nucleus
is derived from that of carbon by the addition
of two H satellites and one electron, one might
expect the atomie weight of nitrogen to be
14.016, assuming C = 12.00, and H = 1.008
in terms of O = 16. By a slight refinement of
Aston’s positive ray analysis it should be pos-
sible to examine this point.
(h) Atomie energy.
A matter of primary importance which has
emerged from the experiments on the disinte-
gration of atomie nuclei is that the energy of
the H particle as it is ejected from aluminium
atoms by the impact of « particles is 1.40.
times the energy of the impinging « particles.
Even when ejected in a backward direction the
released H particle has kinetie energy about 13
per cent. greater than that of the « particle,
causing its ejection. This additional energy
must come from the atom in consequence of its
disintegration. We have therefore in these
experiments of Rutherford strong indications
of a method of attack which, if followed up,
may open a way to the release of the stores
of atomic energy existing in ordinary materials
about us.
(1) H, particles.
In addition to the long range H particles
liberated from nitrogen, the passage of « par-
tieles through oxygen as well as through nitro-
gen gives rise to much more numerous swift
atoms which have a range in air of about 9
ems compared with that of 7.0 em. for the col-
liding « particles. From preliminary observa-
tions on these particles they appear to have a
mass of 3 and to carry a positive charge 2e.
They would thus seem to be the nuclei of an
isotope of helium. A number of experiments
have been made by Rutherford with « particles
traversing gases other than oxygen and nitro-
230
gen with the object of definitely establishing
the origin of these particles. The imperfee-
tion of metal foils, used in the experiments,
from the point of view of « rays is very great
and as yet no very final conclusions can be
drawn from the observations. So far, there is
always the possibility that these particles may

ticles obtained from nitrogen are from five to

ten times as numerous as the H particles so
that if these particles really originate in the
nuclei of nitrogen atoms, if is clear that the
nitrogen nuclei can be disintegrated in two
ways and that the two forms of disintegration
must be independent and not simultaneous.
Since the H, and « particles both carry the
positive charge 2e, and the range of the former
97
is 27 t
per cent. greater than that of the latter,
it can easily be shown that the H, particles
have a velocity 20 per cent. greater than that
of the « particles. The kinetic energy of the
H, particles must therefore be about 8 per
cent. greater than that of the 7 em. range «
particles. If, therefore, the H, particles are
ejected from nitrogen nuclei by the « particles
there must be a gain of 8 per cent. in energy
of motion even though we disregard the sub-
sequent motion of the disintegrated nucleus
and of the colliding @ particle. It will be
interesting to follow developments in connec-
tion with these H., particles. If their existence
be confirmed by future experiments and it can
be shown definitely that they originate in the
nuclei of atoms of such elements as oxygen
and nitrogen, then we shall have in their pro-
duction a second example of the release of
atomic energy through the agency of « rays.
(j) Alpha particles.

ing H particle. In Shimizu’s experiments he
found that about one in every three hundred
% rays traversing air produce a branched track.
These branched tracks cannot therefore have
been produced by the ejection of an H particle.
One striking feature of the Shimizu branched
tracks is that their shapes and sizes are very
similar and the lengths of the two limbs of the
branches ave approximately the same. The
angle between the two branches seems to vary
but little and judging from the photographs,
an example of which taken from Shimizu’s
paper is shown in Fig. 2, it appears to be
about equal to a right angle. With these
branched tracks the branching always takes
place near the end of the path of the « particle.

was about 107°. This fact, together with the
observed relative length of the spur and the
track of the deflected « particle seems to show
that the spur was due to an oxygen atom re
coiling under close impact with the alpha pavr-
ticle.. The Shimizu branched tracks, however,
appear to be similar to what one would expect
to get, on the basis of Darwin’s calculations,
in a closed collision between an « particle and
the nucleus of a helium atom.
This idea naturally suggests that we have in
the Shimizu branched tracks examples of the
disruption of nuclei with the liberation of
He," or alpha particles. If this conjecture
should turn out to be correct it would indicate
that « particles can exist as definite units
within the nuclei of atoms of one or more of
the gases which make up air. It would be of
interest to see if the Shimizu tracks ean be ob-
tained in pure nitrogen and also in pure
oxygen and other simple gases. Since « par-
ticles are known to exist at definite units
within the nuclei of the atoms of the radio-
active elements, it would not be surprising to
find their oceurrence in the
element such as oxygen.

tonic isotope of helium can exist as a distinet

least serve as guides in arranging schemes of

A yather suggestive set of models of the

oxygen, based on the ideas of Rutherford is
shown in Figs. 3, 4, 5, and 6. In these, the
particles H,, He,” and Hes are utilized as
constituent units. Similar models can be easily
made for the nuclei of the atoms of other
elements. From these models one would

PROGRESS IN METRIC STANDARDI-
ZATION
Mark Twatn remarked that people talked
a great deal about the weather and yet he never
heard of anybody doing anything about it.
The same observation might also be made in
reference to the metric system. As scientists
we believe in it and through our organizations
such as the American Association for the Ad-
vancement of Science, the American Chemical
Society, etc., we pass resolutions in favor of
its adoption, but we do little towards making
its use more general. We use the metric sys-
tem in certain parts of our work but we con-
tinue to purchase our chemicals and. supplies
on the basis of the so-called English “system.”
The American Chemical Society has resolved
to “do something about it” and the first step
is to purchase our chemicals and supplies on
a metric basis and thus “clean our own house.”
The manufacturers and dealers are entirely
willing to cooperate, but they feel that it is
absolutely necessary for the consumers to take

wnits, has been compiled by the Metric System
Committee. Cf. J. Ind. and Eng. Chem. 13,
1068 Nov. 1921. Several firms already use
metric packages and some of them exclusively
such as the Eastman Kodak Company, Powers-
Weightman-Rosengarten Co., ete.
Users of chemicals are now asked to write
their specifications in metric units in order to
aid in this movement. Over 300 colleges and
universities have already agreed to cooperate
in the movement, with only one institution
known to be opposed to the change. Over 250
technical firms have agreed to purchase their
pure chemicals and chemical supplies in metric

packages. Firms have been urged to write
to the Committee “even if opposed to the move-
ment.” It is significant that less than 3 per
cent. of those heard from are opposed, which
prompts us to believe that in a short time pure
chemicals in America may be packed exclusive-
ly in the standard metric packages as recom-
mended by the Committee on Guaranteed Re- -
agents and Standard Apparatus (cf. J. Ind.
Eng. Chem. May 1921), Dr. W. D. Collins,
Chairman.
We now ask that all scientists—physicists,
biologists as well as chemists—make a point of
ordering chemicals in metric units. It is not
practicable to reach by letter all of the teachers
of science in our schools and colleges as well
as those using chemicals in the industries, henee
we are making this general appeal so that the
transition period may be made as short as
practicable. We have had printed “stickers”
stating that “orders must he filled and billed
in metric units” which will be sent to any cor-
respondent for the asking.
No scientist would willingly join a move-
ment which would work an injury to American
industry. We have considered the question
whether the compulsory adoption of the metrie
system would be injurious to industry and we
believe that it would be of distinct benefit not
only in world trade but in our intercourse here
at home. The DeLaval Separator Company
has already changed over to the metric basis
in a purely mechanical enterprise and they
find that the cost of the change does not even
“show up” in the manufacturing costs.
In education the saving by abolishing our
out-of-date system would be enormous, esti-
mated by Dr. Wolf to be an aggregate of a
million years in a single generation. The pro-
motion of understandings with other nations
tends to the promotion of world peace and
the cost of not adopting the system used by
practically every nation in the world except
the English and ourselves may far exceed in
a single generation the cost of making the
change.
We need local committees to get the metric
system properly taught in the schools. Doc-
tors are writing prescriptions in metrie units
Marcu 3, 1922]
voluntarily already on a small seale. Sys-
tematic effort would doubtless increase their
number many fold. The old apothecary
weights might be completely abandoned if ef-
fort were expended in that direction. Finally,
legislation making the use of metrie units obli-
gatory would come as a matter of course when
the public understood that prejudice and the
supposed interest of a few gage manufacturers
was keeping us from the only rational system
of weights and measures.

THE BANDING OF BIRDS
On the seventeenth of January, 1922, in
response to an invitation from Mr. L. B.
Fletcher and others interested in the banding
of birds, over a hundred _ ornithologists,
licensed bird-banders and candidates for
licenses, met at the Boston Society of Natural
History Building in Boston and organized a
new ornithological society to be known as the
New England Bird Banding Association. The
meeting was addressed by 8. Prentiss Baldwin
of Cleveland, Ohio, who, during the last six
years, by introducing bird-trapping as a means
of banding birds, has done so much to show
the scientific possibilities of the work. The
Bureau of Biological Survey in Washington
was represented by Major KE. A. Goldman, who
spoke of the bureau’s plans in connection with
the movement, strongly endorsing the organ-
ization of the new association and recommend-
ing the formation of other organizations of the
same character at appropriate localities in the
United States and Canada.
Members of Audubon societies and bird elubs
in several states, and of the Nuttall and Essex
County Ornithological clubs, and state ornith-
ologists were present at the meeting, as well as
a representative of the Canadian game warden
service.
At this writing, January 24, 1922, the asso-
ciation has an enrollment of about three hun-
dred members who are scattered over all parts
of the territory covered by the organization,
namely, New England, Quebec, and the mari-
time provinces.

It may be of interest to ornithologists gen-
erally to read an outline of the purposes and
plans of the new association which has been
formed under the stimuli furnished by the
national movement, administered by the Bureau
of Biological Survey; by the more general ap-
preciation of the scientific aspects of bird
banding as shown, in particular, by Mr. Bald-
win’s recent work; and by the interesting and
valuable data already obtained by previous
bird-banding operations.
In the beginning it was felt that the some-
what disappointing results secured from bird
banding in the United States to date were due
to the workers being too scattered and unco-
ordinated; to a lack of national support of the
plan and the too general character of the
ornithological problems bird-banding opera-
tions were expected to solve.
From a study of the situation we came to
believe that we could obtain the best results:
1. By organizing a regional association of bird
banders, meaning by this, bringing together a
membership from an area possessing one or more
migration highways, along which trapping sta-
tions could be established to furnish, by intensive
attack, fairly speedy answers to certain specific
migration problems, thus early demonstrating to
members the scientifie value of bird banding
with the consequent stimulus to continue the work
which it is expected will ultimately solve more
ornithological riddles, aid in the solution of
others and create new problems not now antici-
pated ;
2. By having the members meet together as
often as possible to discuss results, methods and

Lau-

future plans and to gather inspiration from their
fellows after the manner of scientific societies
generally, in this way using the combined knowl
edge of the association to advance the work;
3. By appealing for the support of Audubon
societies all over the country on the ground that
bird banding is a bird-protection movement, since
to an important extent it will be possible in the
future to substitute an examination of a
bird for the study of a dead one;
4. By ensuring as far as possible the perma-
nence of the movement by means of institutional
trapping stations operated by or in connection
vith Audubon societies, natural history societies,
bird clubs, departments of ornithology or zoology
at colleges and universities, bird sanctuaries,
state and national parks, etc., in addition to sta-
tions operated by individuals; and
5. By establishing a convenient local depository
of all bird-banding records made by members (an
exact. copy of the same of course being sent to
the Biological Survey) in appropriate quarters
where they may be studied by members of the
association and others.

CONFERENCE ON BUSINESS TRAINING OF
THE ENGINEER AND ENGINEERING
TRAINING FOR STUDENTS OF
BUSINESS
Tue United States Commissioner of Hduea-
tion is calling a second public conference on
commercial engineering on behalf of a com-
mittee on commercial engineering appointed by
him to investigate business training of engineers
and engineering training for students of busi-
ness.
The conference will be held May 1 and 2
at the Carnegie Institute of Technology in
Pittsburgh. President Arthur Hamerschlag of
this institution is a member of the committee
which is composed of prominent deans of
schools of engineering, and of commerce in our
larger universities, and of engineers and busi-
ness men who are nationally known for their
interest in the reduction of the costs of pro-
duction, distribution, transportation, — ete.,
through better training in schools and colleges
of the perscnnel of industry and commerce.
SCIENCE
[Vou. LV, No. 1418
The conference will be open to the public.
Invitations to appoint delegates to the Pitts-
burgh Conference, however, will be sent by the
commissioner of education to commercial and
trade organizations, engineering and scientific
societies, educational institutions and other
eroups as well as to prominent individuals.
Owing to the timeliness of the subject, the
conference in Pittsburgh will even have greater
national significance than the first puble con-
ference on this question, which was held in
Washington two and one half years ago under
the direction of this committee on commercial
engineering of which Dr. Glen Levin Swiggett
of the Bureau of Education is chairman. He
says:
The four major topics of the conference will be
presented and discussed at general and round
table sessions by business men, educators and
engineers, contributing to the construction of a
cooperative program between education and busi-
ness for the better coordination of all productive
distributive processes in trade com-
merece. It is planned to have the second confer-
ence even more constructive than the first, since
which time the curricula of 29 of the 119 engi-
necring colleges reporting to the Bureau of Edu-
cation have been favorably modified to include
one or more of the four committee recommenda-
tious. Outstanding topics at the Pittsburgh con-
ference will deal with the new problems that have
recently arisen in modern industries, the solution
of which demands a more scientific approach to
include job analyses and personnel specifications
and a translation of these into a new and teach-
able content for use in our engineering and com-
and and
merce schools; with the training of the engineer
for a better understanding of problems relating
to community development; and with the training
of the engineer for management of overseas engi-
neering projects.
GIFT OF THE ROCKEFELLER FOUNDATION
FOR A SCHOOL OF HYGIENE IN LONDON
ACCORDING to a press dispatch to the New
York Times the British minister of health an-
nounced on February 21 that the Rockefeller
Foundation had offered to provide $2,000,000
toward the cost of building and equipping a
school of hygiene in London. This offer is on
the understanding that the British Government
MArcH 3, 1922
shall accept the responsibility of providing for
appointing the staff and maintaining the school
when established.
Such a school was recommended by the com-
mittee appointed early in 1921 to consider pro-
vision for pest graduate medical examination
in London, and the recommendation was fur-
ther considered by an expert committee with
the minister of health as chairman.
in view of the diffienlty at present of financ-
ing the scheme, the whole case was presented to
the Rockefeller Foundation as one in which it
might think it well to cooperate in the general
interest of progress in public health.
This gift follows the donation of £1,000,000
to the University of London and University
College Hospital.
For providing the staff and maintaining the
proposed school of hygiene, the government
will have to allocate £125,000 spread over a
So long ago as 1915,
the Institute of Hygiene planned a great cen-
tral building in Marylebone Road, but the es-
timate at that date of £47,000 for the build-
ing alone made it impossible to proceed. In
March of last year a new estimate was obtained
and it was found that the cost would appvoxi-
mate £125,000. The British Government felt
it impossible to allocate the necessary funds
at a period of such financial difficulty as the
present.
In June, 1920, the Rockefeller Foundation
announced that it had provided endowment
yielding £30,000 annually for the University
of London to aid medical study. At that time
it was said that the funds would be used to
support a new staff in anatomy at the college,
for an increase in the staff of physiology, for
a full-time unit in obstetrics and for various
items of increased laboratory and clinical ser-
vice. In a-statement issued at the time of the
gift by Dr. George H. Vincent, president of the
Rockefeller Foundation, it was said:
Since the Rockefeller Foundation is cooperating
with governments in many parts of the British
Empire, it recognizes the importance of aiding
medical education in London, where the training
of personnel and the setting of standards for
health work throughout the eimpire are so largely
centered.

THE SHELDON MEMORIAL
A FEW months ago, as already noted. in
Sctencs, the Sheldon Committee
was organized to receive subseriptions toward
a foundation in honor of the late Dr. Samuel
Sheldon, professor of electrical engineering
and physies at the Polytechnic Institute of
Brooklyn, 1889-1920.
As chairman of the committee, I am glad to

report that we are now turning over to the
Treasurer of the Polytechnic Institute $15,018,
the sum so far paid in by more than 1,000
There are still a few unpaid sub-
scriptions and we are hoping to secure enough
further pledges to raise the fund to at least
$20,000. Although the sum raised was hardly
sufficient really to endow a laboratory, the cor-
poration of the institute has ordered that the
Electrical Measurements Laboratory be known
hereafter as the Samuel Sheldon Memorial
Laboratory of Electrical Measurements and its
subscribers.
236
members have collected among themselves an
additional $1,000 for immediate improvements
and the installation of a memorial tablet. In
this manner, the entire fund raised by our com-
mittee will be invested in the form of a trust
and the income used perpetually for the main-
tenance of this laboratory which will thereby
become one of the best laboratories of electri-
cal measurements in the country.
I wish also to note the general sentiments of
esteem and admiration expressed toward Dr.
Sheldon, the loyalty of several hundred former
students to his memory, and the enthusiasm
found within the splendid institution to which
with such conspicuous success he devoted so
many years of his life.

We learn from the London Yimes that the
Commonwealth Government will place a war-
ship at the disposal of astronomers who ave
‘going to visit the northwest of western Australia
in September to observe the total eclipse of the
sun on September 21. The apparatus is to
be established at Wollal, a lonely point on the
coast between Port Hedland and Broome. The
party, for whom an observation camp will he
created, includes Dr. W. W. Campbell, director
of the Lick Observatory, California, and Mrs.
Campbell; Dr. Moore and Dr. Trumpler, also
of the Lick Observatory; Dr. and Mrs. Adams,
of New Zealand; Professor Chant and three
assistants from Toronto Observatory, and Aus-
tralian astronomers. The Naval Meteorological
Department is making arrangements for the
reception of the visitors. The path of totality
will be covered as follows: It begins in
Abyssinia, and passes over the center of Italian
Somaliland and across the Maldive Islands,
where, Mr. J. Hvershed, director of the Kodai-
kanal Observatory (India), will be stationed
Thence it passes across the Indian Ocean to
Christmas Island, the most favorable of the
places where observation is feasible. Two ex-
peditions are going there, one a British expe-
dition, from Greenwich, consisting of Mr. H.
Spenser Jones, chief assistant, and Mr. P. J.
Melotte, the discoverer of the eighth satellite
of Jupiter; the other a joint Dutch and Ger-

possibly accompany.
REFERRING to a report from Australia that
the southern station of the Harvard College
Observatory may he moved from Arequipa,
Peru, to Queensland, the Alumni Bulletin states
that there 1s no immediate prospect of such a
change. An influential member of the Queens-
land government suggested recently that a site
might be found there which would prove more
advantageous than Arequipa, and received per-
mission from Harvard to go so far as to have
meteorological observations made to determine
the conditions for astronomical work in Queens-
land. No definite offer of a site has been re-
ceived, however, and it is said to be unlikely
that any decision one way or the other will be
made for the present.
Proressor Homer R. Dinu, director of the
vertebrate exhibit at the State University of
Towa, will conduct an expedition to the South
Seas some time next year. The primary object
will be the collection of fish, but it is hoped
that many birds and small mammals may also
be taken. Several months will be spent visit+
ing various islands including the Marquesas,
Society, Friendly, Samoan and Fiji groups.
Stops may also be made in New Zealand and
Japan. Other members of the party will
include Mr. E. W. Brown, of Des Moines, who
is fmancing the trip, and his wife and son,
Robert Brown. The latter is at present study-
ing under Professor Dill. Mrs. Brown, who
has had considerable experience in fish paint-
ing, will serve as artist on this trip and make
sketches of the different species as they appear
in life. A former expedition in 1920 with the
same personnel was made to the Hawaiian
islands and as a result many species of fish
were added to the university collection. The
fish will be shipped back to the United States
in large tanks which are now being constructed.
A new preserving fluid discovered by Pro-
fessor Dill was found to be satisfactory on
the Hawaiian expedition and will be used again
on this trip. It retains the natural coloring of
the dead fish to a large extent, which is an
important factor in the collection of many of
the highly colored tropical species.

DISCUSSION AND CORRESPOND-
ENCE
DUTY ON ENGLISH BOOKS
In a book-importer’s catalogue we read:
““Tt may be noted that all foreign books can be
imported free of duty, as well as English books,
more than twenty years old at the date of im-
portation. ’’
Such, in fact, is the law of the land; but, in
its application we have found grave modifica-
tions.
Importing a series of English scientific maga-
zines some months ago we were informed that
the shipment was in the hands of an import-
ing or forwarding agency and would be seen
through the customs and sent on upon payment
for services and duty charges. In compliance
with this request an amount covering charges
for services and the portion of the series duti-
able at the usual fifteen per cent. was forwarded
the agency. The books arrived safely, appar-
ently untouched or undisturbed in any way by
customs officials. The dutiable portion con-
After
some time a bill came requesting payment for
duty on the remaining three-fourths of the
shipment, on that portion of the series printed
over twenty years ago. Inquiry elicited the
information that duty had been demanded and
had been paid by the agency on the whole ship-
ment. Further inquiry established the fact that
duty on the whole shipment had been based
on a certain precedent where an importer of
books had brought in this country an integral
“set”? of books, some less, some more than twen-
ty years old and that the “set” was looked
upon as all dutiable, indivisible. So in the
“spirit” of the law our magazines were all
dutiable, whatever might be their age or the
age of the majority of them. So the law might
call, as it did in our ease, for a duty of $6.00,
but its “spirit” called for $18.00 more.
Conclusion for individual importers: see to
it that your foreign exporters do not send you
the older and newer numbers of magazines in
the same box or shipment.

We can scarcely refrain from suggesting, in
the present depleted state of our Treasury De-
partment, that all revenue laws should be con-
structed for “spirit” attachments.

ALTERNATE BEARING OF FRUIT TREES
In view of the heightened interest in the
alternate bearing of fruit trees and in fruit
bud formation it may be interesting to quote
the following passage from the Magazine of
Horticulture for 1847, volume 13, page 438.
The note was written by Charles M. Hovey,
editor of the magazine, author of several well-
known horticultural works, and often called
the father of the American strawherry, after a
visit to the Pomological Gardens af Salem,
Massachusetts, of Robert Manning, one of the
most thorough and accurate students of horti-
culture in the early days when amateur interest
in fruits ran high:
Passing a Baldwin apple tree in full bearing,
Mr. Manning stated that it was one on which he
tried the experiment of changing the bearing
year. It is well known that the Baldwin only
bears every other year. To obviate this was the
object of Mr. Manning; and, in the spring of
1846, he spent nearly two days in cutting off all
the blossoms. It had the desired effect; this year,
the tree is completely loaded with fruit. This
experiment is valuable, for it shows that, in a
large orchard, when the trees, by chance, nearly
all fruit the same year, any number of them can
be made to fruit in the alternate year simply by
the labor of destroying all the blossoms.

THE WRITING OF POPULAR SCIENCE
To tHe Epitor or Science: In looking
through the “List of One Hundred Popular
Books in Science” prepared by the Washing-
ton Academy of Sciences for the guidance of
libraries with limited income, one is struck by
the number of foreign books. There are
thirty-five British authors, two French (Fabre
and Maeterlinck) and one German. (Hinstein) ;
that is, in searching for the best books on the
SCIENCE
241
various: sciences, regardless of nationality, it
was found necessary to go abroad for 38 per
cent. of them.
This is curious since in writing for Amer-
ican readers an American author has a decided
advantage in that he understands their point
of view and can use more or less local illus-
trations and comparisons and make allusions to
familiar things, which are important factors
in the popular presentation of scientific ques-
tions.
In spite of this natural handicap on the
foreign author, British books form more than
a third of this carefully selected list, so it is
evident that the British are doing better work
in the popularization of science than we are, a
conclusion that is confirmed by a comparison
of imported and domestic books in publishers’
catalogues. We have in this country, for
instance, nothing to compare in style of writing
and attractive illustrations with the “Outline.
of Science” edited by Professor J. Arthur
Thomson, which is now being published in
parts at 1 shilling, 2 pence, as was Wells’ “Out-
line of History.” I may add that Science
Service, which has been scouring the country
for a year for popular science writers, has been
obliged to go to England for them in many
cases.
This is difficult to account for since our
American schools give much more attention to
the sciences and to the teaching of English
composition than do the British schools and
since we have such an abundance of fluent and
facile writers in fiction and journalism and
since we have a wider reading public than any
other country. But it is questionable whether
the interest of the American people in scien-
tifie questions has kept pace with the growing
importance of science in human life. In fact
some say that science is losing ground in popu-
lar esteem. For instance, Dr. Alfred H.
Brooks, of the U. 8. Geological Survey, said in
his recent presidential address to the Washing-
ton Academy of Sciences:
I venture the opinion that there is to-day rela-
tively less popular knowledge of science and less
interest in its methods and achievements than
there was a generation ago.
This is a discouraging statement in view of
242
the unprecedented expenditure of money on
scientific education in American schools.

QUOTATIONS
WILLIAM JENNINGS BRYAN ON EVOLUTION!
Tue only part of evolution in which any con-
siderable interest is felt is evolution applied to
man. A hypothesis in regard to the rocks and
plant life does not affect the philosophy upon
which one’s life is built. Evolution applied to
fish, birds and beasts would not materially
affect man’s view of his own responsibilities
except as the acceptance of an unsupported
hypothesis as to these would be used to support
a similar hypothesis as to man. The evolution
that is harmful—distinetly so—is the evolution
that destroys man’s family tree as taught by
the Bible and makes him a descendant of the
lower forms of life. This, as I shall try to
show, is a very vital matter.
The latest word that we have on this subject
comes from Professor Bateson, a high English
authority, who journeyed all the way from
London to Toronto, Canada, to address the
American Association for the Advancement of
Science the 28th day of last December. His
speech has been published in full in the Janu-
ary issue of SCIENCE.
Professor Bateson is an evolutionist, but he
tells with real pathos how every effort to dis-
cover the origin of species has failed. He takes
up different lines of investigation, commenced
hopefully but ending in disappointment. He
concludes by saying, “Let us then proclaim in
precise and unmistakable language that our
faith in evolution is unshaken,” and then he
adds, “our doubts are not as to the reality or
truth of evolution, but as to the origin of spe-
cies, a technical, almost domestic problem. Any
day that mystery may be solved.” Here is
optimism at its maximum. They fall back on
faith. They have not yet found the origin of

species, and yet how can evolution explain life
unless it can account for change in species? Is
it not more rational to believe in creation of
man by separate act of God than to believe in
evolution without a particle of evidence?
The objection to Darwinism is that it is
harmful, as well as groundless. It entirely
changes one’s view of life and undermines
faith in the Bible. Evolution has no place for
the miracle or the supernatural. It flatters the
egotist to be told that there is nothing that his
mind cannot understand. Evolution proposes
to bring all the processes of nature within the
comprehension of man by making it the ex-
planation of everything that is known. Crea-
tion implies a Creator, and the finite mind
cannot comprehend the Infinite. We can under-
stand some things, but we run across mystery
at every point. Evolution attempts to solve
the mystery of life by suggesting a process of
development commencing “in the dawn of time”
and continuing uninterrupted up until now.
Evolution does not explain creation; it simply
diverts attention from it by hiding it behind
eons of time. If a man accepts Darwinism, or
evolution applied to man, and is consistent, he
rejects the miracle and the supernatural as
impossible. He commences with the first chap-
ter of Genesis and blots out the Bible story of
man’s creation, not because the evidence is
insufficient, but because the miracle is incon-
sistent with evolution. If he is consistent, he
will go through the Old Testament step by
step and cut out all the miracles and all the
supernatural—the virgin birth of Christ, His
miracles and His resurrection, leaving the Bible
a story book without binding authority upon
the conscience of man.

Christians do not object to freedom of
speech; they believe that Biblical truth can
hold its own in a fair field. They concede the
right of ministers to pass from belief to ag-
nosticism or atheism, but they contend that
they should be honest enough to separate them-
selves from the ministry and not attempt to
debase the religion which they profess.
And so in the matter of education. Chris-
tians do not dispute the right of any teacher to
be agnostic or atheistic, but Christians do deny
Marcu 3, 1922]
the right of agnostics and atheists to use the
public school as a forum for the teaching of
their doctrines.
The Bible has in many places been excluded
from the schools on the ground that religion
should not be taught by those paid by public
taxation. If this doctrine is sound, what right
have the enemies of religion to teach irreligion
in the public schools? If the Bible cannot be
taught, why should Christian taxpayers permit
the teaching of guesses that make the Bible a
le? A teacher might just as well write over
the door of his room, “Leave Christianity be-
hind you, all ye who enter here,” as to ask his
students to accept an hypothesis directly and
irreconcilably antagonistic to the Bible.
Our opponents are not fair. When we find
fault with the teaching of Darwin’s unsup-
ported hypothesis, they talk about Copernius
and Galileo and ask whether we shall exclude
science and return to the dark ages. Their
evasion is a confession of weakness. We do
not ask for the exclusion of any scientific truth,
but we do protest against an atheist teacher
being allowed to blow his guesses in the face of
the student. The Christians who want to teach
religion in their schools furnish the money for
denominational institutions. If atheists want
to teach atheism, why do they not build their
own schools and employ their own teachers?
If a man really believes that he has brute blood
in him, he can teach that to his children at
home or he can send them to atheistic schools,
where his children will not be in danger of
losing their brute philosophy, but why should
he be allowed to deal with other people’s chil-
dven as if they were little monkeys?
We stamp upon our coins “In God We
Trust”; we administer to witnesses an oath in
which God’s name appears; our President takes
his oath of office upon the Bible. Is it fanatical
to suggest that public taxes should not be em-
ployed for the purpose of undermining the
nation’s God? When we defend the Mosaic
account of man’s creation and contend that
man has no brute blood in him, but was made
in God’s image by separate act and placed on
earth to carry out a divine decree, we are de-
fending the God of the Jews as well as the
God of the Gentiles; the God of the Catholies
SCIENCE
243
as well as the God of the Protestants. We
believe that faith in a Supreme Being is essen-
tial to civilization as well as to religion and
that abandonment of God means ruin to the
world and chaos to society.
Let these believers in “the tree man” come
down out of the trees and meet the issue. Let
them defend the teaching of agnosticism o
atheism if they dare. If they deny that the
natural tendency of Darwinism is to lead man.
to a denial of God, let them frankly point out
the portions of the Bible which they regard as
consistent with Darwinism, or evolution ap-
plied to man. They weaken faith in God, dis-
courage prayer, raise doubt as to a future life,
reduce Christ to the stature of a man, and make
the Bible a “serap of paper.” As religion is
the only basis of morals, it is time for Chris-
tians to protect religion from its most insidious
enemy.
SCIENTIFIC BOOKS
James Hall of Albany, Geologist and Paleon-
tologist, 1811-1898. By Joun M. Cuarke.
Pp. 565, illustrated. Albany, 1921 (8S. C.
Bishop, $3.70, net).
In this book we have a very informative and
highly entertaining history, not only of Pro-
fessor James Hall, but of most of the other
pioneers in American geology and _ paleon-
tology as well. It is replete with interest for
all men of science.
Hall was an extraordinary man in many
ways, turning out a prodigious amount of
geologic work, and furnishing, by his dyna-
mism, an inestimable “creative impulse to study
and research.” He was sensitive to a remark-
able degree, irascible, and with a surpassing
ambition. His nervous system always taut, he
“played on a harp of a thousand strings.” In
consequence he appears to have been in trouble
with most of his associates, and yet he was “a
confiding man, forever trusting the plausible
stranger, even while distrusting his most de-
voted friends.” He lost much money in
mining !
Hall’s scientific career began in 1836 and
for sixty-two years he dominated Paleozoic
geology, and more especially paleontology, in
244
North America. Thirteen great quarto vol-
umes and at least a five-foot shelf of works on
paleontology are his enduring monuments.
The wonderful Fourth District of western
New York was Hall’s “patent”? and in it he
labored for five years unraveling its geology,
“the most excellent piece of field work he ever
did,” in the course of which was established a
large part of the New York System of geolog-
ical formations. Then came the ever widening
Paleontology of New York, the dominant note
of Hall’s long life. An insatiable collector,
without ever knowingly having a duplicate
fossil, he sold the worked-up collections only to
buy and collect others with the money so ob-
tained. Appropriations or none by New York
or other states, he went on constantly garner-
ing more material.
As one reads the book, the thought comes
readily that New York State has been. the
mother of geologists—one almost comes to the
belief that all American geologists between
1843 and 1890 came from the Empire State or
got their training there. We also see the
passing show of the master minds that devel-
oped the geology of the entire Mississippi
Valley, since they were all for one reason or
another worshippers at the Albanian shrine.
“Fis influence guided official geologic move-
ments in every state where they were inau-
gurated, and in many his hand took a helms-
man’s part.” Hall’s influence was also great
in Canada between 1843 and 1869, since his
relations with the director of the Geological
Survey of Canada, Sir William Logan, “were
openly harmonious.”
Hall’s zenith of scientific attainments came
between 1857 and 1861. Some years before, he
presented at the Montreal meeting of the
American Association for the Advancement of
Science his “most notable performance in
philosophical geology,” The Geological His-
tory of the North American Continent. In
this essay, published in 1861, he set forth two
essential propositions in regard to mountain
making, and they are the fundamentals on
which our modern conception of these struc-
tures depends. These are:
1. That ranges of folded mountains exist only
where sediments have uniformly accumulated to
SCIENCE
[Vou. LV, No. 1418
maximum thickness and that such maximum
accumulation is possible only by corresponding
depression of the sea bottom along the edges of
continents delivering such sediments. . .
2. That folded mountains result from the
crumpling of the upper layers only of these ac-
cumulated deposits, a consequence of the adjust-
ment of the later sediments to a deepening but
contracting depression.
When Hall was sixty years of age, he was
“at the threshold of his greatest productive-
ness,” and he worked in this way:
Of all the corps of men engaged upon this
work, Mr. Hall himself was, in these days, the
most diligent. Nothing that entered into his
publications escaped his criticism and review and
he was keen and quick in the preparation of his
manuscript. Up and at his desk soon after break
of day, with a cup of tea and a panada at his
elbow, he found his quiet hours before his
assistants came around. And after they had gone
there were the evening hours which seldom found
him away from his work room. It was his habit
when at work to sit before his desk on a revolving
piano-stool; his backbone needed no support and
an easy chair he abhorred. But alongside his
desk he kept, for his callers, a deep scoop-shaped
great chair into which the visitor shriveled as he
sank down into insignificance near the floor, while
his vis-a-vis, erect on his stool, towered majes-
tically over him. It was a strategic advantage
and in many an engagement commanded the
enemy ’s works.
When the reviewer went to Albany in 1889
as Hall’s private assistant, the latter was a pic-
turesque old man:
His round, full-bodied figure, his heavy snowy
beard running well up over his ruddy cheeks, an
always erect carriage and a square level look out
from under thick brows and over his Moorish
nose; dressed in an old coat and in trousers
which buttoned down the sides after the fashion
of 1830, he was bound to attract attention and
curiosity. Every morning. . . his man Tom drove
him from his home in a broken-down, one-seated
eart which had once owned a top but lost it long
since, drawn by a broken-down old nag which
had also seen better days and had like as not
been taken in exchange for apples or old speci-
men boxes, his capacious snow-crowned figure
eapped with a chimney-pot hat towering above his
diminutive driver—the jogging figure through the
Albany streets was sure to compel notice.
Magcu 3, 1922]
Extolled by LeConte as the “founder of
American geology,” and by MeGee as the
“founder of American stratigraphy,” said by
Dana to be the man without whom “the geo-
logical history of the North American con-
tinent could not have been written,” Hall’s
present biographer concludes that he ‘was in
truth the apostle of historical geology.” Much
praise is due Dr. Clarke for the lively way in
which he sets Hall—and many of his contem-
poraries—before us in these pages. The task
was a great one, attended with peculiar diffi-
culties, and its accomplishment reflects high
credit upon the author. The paleontologie sun
rose in New York in 1836, and its warmth still
radiates from the Hmpire State throughout the
North American continent!

Sargent’s Electric
Water Bath
With
Constant Temperature Control
i MANUFACTURED IN PART UNDER PATENT 1083592
The demand for a water bath electrically heated and provided with a constant tempera-
ture control that is sufficiently sensitive for the general laboratory has caused us to design and
manufacture the illustrated apparatus.
The range of constancy in the temperature of this water bath is TGs
While this degree of accuracy is not sufficient for the most exacting research work such
as experiments in electric conductivity it is well within the margm of variation required by
the general analytical chemist.
It is especially useful in digestion work where a constancy of selectéd temperature is
desired up to the boiling point of water.
It is also a most desirable apparatus for evaporating at low constant temperatures as in
potash determinations in fertilizer laboratories or where there is danger of breaking up a
residue from over heating.
The regulator may be set to produce and maintain any temperature—between a few
degrees above room temperature and the boiling point of water.
Dishes, round or flat bottom flasks or acetylization flasks may all be used with this
apparatus. A support is provided to hold condensers, thermometers, etc.
The area of the bath is 13 x 13 inches and the top is provided with four holes each 5
inches in diameter and provided with concentric rings.
Made for stock for 110 volt and 220 volt currents and may be used on either alternating
or direct current.
It is provided with an attachment for maintaining a constant water level in the bath and
with cord and plug for attaching to the electric line and full directions for operation.

DOCTORATES CONFERRED IN THE
SCIENCES BY AMERICAN UNI-
VERSITIES IN 1921
THROUGH the generous cooperation of the
registrars of the various American universities
granting doctorates in the sciences, the Re-
search Information Service of the National
Research Council is able to offer the following
compilation of doctorates. granted during the
collegiate year 1920-1921. Through this same
cooperation statistics are now available for the
period 1916-1919. The information for these
three years has not been compiled heretofore
and therefore was lacking in the tables as
published last year (Screncr, 52, 478, 514).
These figures are of value as an indication of
the academic activity during the World War.
As would be expected, the number of doctor-
ates fell off as the size of the American army
inereased (1917, 372; 1918, 293; 1919, 180).
This is a confirmation of the acknowledged fact
that the scientific men of the country played
an increasingly important part in the activities
of the army and navy.
In 1921 there were 332 doctorates conferred
in the natural sciences by 32 institutions, as
compared with 323 by the same number of
institutions in 1920. (The figures reported in
1920 by institutions and by subjects have been
corrected in certain cases from later informa-
tion). It is interesting that the figures for
1917 should be so much higher than those for
any other year reported in the tables. How
long will it be before those figures are again
reached ?
Marked changes in the order of institutions
are in the shift of Minnesota from nineteenth
place in 1920 to tenth place in 1921, and of
George Washington from tenth place in 1920
to twenty-sixth place in 1921. Comparisons of
this kind are of uncertain significance because
the number of degrees granted by an institu-
tion during any collegiate year depends upon
many factors.

THE ORGANIZATION
KNOWLEDGE
Il
The aim of all organized knowledge is to in-
crease the certainty of prediction, or as a
practical question the science of forecasting,
the urgency of which was never more apparent
than it is to-day. As has been said by Jevons,
“With the progress of any branch of science
the element of chance becomes much reduced,”
for “Not only are laws discovered which en-
able results to be predicted but the
systematic examination of phenomena and sub-
stances leads to important and novel discoveries
which can in no sense be said to be accidental.”
The application of this principle to the science
of human relations is obvious, yet rarely recog-
nized with the required degree of clearness.
A vast amount of human activity continues
to be carried on, crude as it may be, in dis-
regard of past experience but of necessity as
an adventure or speculation, the evil results
of which are most likely to fall upon others
than those directly concerned. It is not only
OF
280
true that “hopeless causes do not always fail”
(in the temporary human sense), but that
wrongful causes or courses may prove profit-
able—for a time—and to those directly con-
cerned. It requires to be clearly kept in mind
in considering civilization as a science of hu-
man relations that in this respect the interests
of the individual and society may be diametri-
cally opposed to each other. But just as the
police powers control criminal propensities, so
the powers of organized knowledge and of
demonstrated experience hold in check the reck-
less intellectual speculations of the audacious
but uninformed. In its final analysis the only
eure of a fallacy is a demonstrated fact so
clearly stated and properly applied that the
truth must prevail and prove triumphant.
This conclusion is summed up by President
David Starr Jordan in the remark that “The
final test of truth is its livableness, the degree
to which we trust our lives to it.” However
much falsehood may prevail and prove an in-
dividual advantage—for a time—in the long
run it is only “by means of experience, person-
al and collective, that the human race main-
tains itself on earth.” Such _ experience,
also in the words of Jordan, “concerns
itself chiefly with the relations of objects rather
than with their ultimate constitution or their
intimate nature,” for “it gives the truth actu-
ally needed in actual life and it furnishes the
means for the acquisition of more complete
conceptions whenever in the intricacies of life
such better knowledge is needed.”
The principle here laid down is fundamental
to a science of human relations. When the
demand arises for practical knowledge, for safe
guidance in affairs of business or state, the
first essential need is a basis of agreed upon
facts, only too often wanting in the case of
those who essay upon leadership in the
troubled waters of political, economic, or social
controversy.
It is likewise with every question, great or
small, upon which mankind stands in need of
better knowledge to eliminate the prevailing
error and misapplication of human effort.
Only by organizing knowledge in the manner
here suggested will it be possible to seeure the
SCIENCE
[Vou. LV, No. 1420
future against the vast amount of erroneous
conclusions which now hamper progress in
practically every important direction in which
further progress is most essential for the good
of all mankind. No elaborate philosophical
treatise on the “Foundations of Knowledge”
or the “Human Intellect” meets this need. If
typhus is at our door or sleeping sickness no
vague advice on preventive measures, however
well meaning, meets our needs of the situa-
tion or the expectations of the public. No
philosophical platitude, no pious phrases of
politics held the Indian in his struggle to sur-
vive in competition with an unlike civiliza-
tion in some respects inferior to the moral and
physical standards of primitive life.
In very truth it is much easier to evolve
speculative theories about knowledge than to
ascertain the truth or the facts concerning
even the most commonplace matters of every-
day existence. Herein lies the conflict between
mathematics and statistics and the menace of
over-emphasis of the mathematical judgment in
matters which are largely questions of facts
and not of philosophical inference. Because
mathematics are useful—if not indispensable—
in astronomy or engineering it does not at all
follow that mathematical speculations can safe-
ly be applied to problems in biology or vital
and social statistics. The practical truths of
every-day life are relative and not absolute,
all more or less conditioned by the human judg-
ment, totally at variance with the ascertain-
ment of the truth of physics or chemistry. The
mode of reasoning most useful in sociology or
political science is essentially different from the
intellectual concept of accuracy in the trans-
mission of sound waves or the transformation
of energy applied to a steam engine or a tur-
bine. Hence I am at a loss to understand the
conelusion of Jevons that “As science pro-
gresses, its power of foresight rapidly increases
until the mathematician in his study seems to
acquire the power of anticipating matters and
predicting what will happen in stated cireum-
stances before the eye of man has ever wit-
nessed the event.” No mathematician gave
a forecast of the coming of the great
influenza epidemic of 1918-19, no weather
Marcu 17, 1922]
forecast of a coming storm depends upon
mathematics, no fall in prices or rise in wages
needs the aid of the mathematician to prognos-
tieate events depending largely on unforesee-
able contingencies, and finally, no mathema-
tician could have or did forecast the great war
and its duration and consequential loss of life
and property. But knowledge properly or-
ganized would aid enormously in developing
the prophetic judgment free from bias or the
influence of custom or tradition. Such organi-
zation should be the first instead of the last,
the most important instead of the most ne-
glected duty of the state. Without it the pres-
ent chaos and confusion must continue, while
the consequences must become more disastrous.
Properly organized knowledge on the multitude
of matters that concern the state and society
would within a single generation do more to
advance the cause.of true civilization of science
and human progress than any other discovery
within the realms of possibility.
Nothing that I have said should be con-
strued as opposed to original thought, to the
fullest uses of the imagination, lead the con-
clusions where they may. Such speculations
concern the individual and represent opinions
which may or may not be accepted as a guide
to action in the affairs of every-day life. I
am concerned with judgments of a public or
universal nature brought forward as a con-
tribution to truth, based upon the ascertained
and digested facts of human experience. I
agree entirely with Professor Dearborn that it
is wrong “to be forever putting facts into the
mind while never providing time to use them
in thought,” and I also agree with his view
that “rules for thinking are wholly unneces-
sary,” just as I am convinced of the non-utility
of a knowledge of technical grammar in the art
of writing. But what belongs to the realm of
the imagination is a thing apart in the life of
a man who is conscious of his intellectual re-
sponsibility in matters of fact and particularly
when the facts represent collective experience
or conclusions drawn from assembled aggre-
gates usually in the nature of statistical data.
No man has a right or a privilege to say that
he knows what to him is only a matter of be-
SCIENCE 281
lief. On all questions of public policy, where
far-reaching consequences are involved in pres-
ent-day action, it is the first duty of the states-
man to make sure of his facts, to clearly differ-
entiate facts from opinion, and to act with
absolute impartiality upon the evidence. Comptes Rendus, 173: 478, 1921.
SCIENCE
[Vou. LV, No. 1422
universal reactions can only do so by shutting
his eyes to the real nature of the phenomena.
It is, in fact, necessary to look in two directions
at once; to be equally alert to detect general
laws or principles, and to perceive special
eases, which in a real and significant sense are
unique.
Not only do the insects thus illustrate the
wonders of life, but they afford us excellent
material for evolutionary studies, whereby we
may eventually understand in some measure
how the most complex structures and reactions
arose. They do this because the species are so
excessively numerous, and there is every reason
to suppose that much of their evolution has
been lateral; that is, by the development of
segregates without the disappearance of the
original stock. Thus it may well happen that
a sufficiently extensive collection will show a
series of forms, along with their prototypes,
the latter still existing under the original con-
ditions. Recent studies have revealed the exist-
ence ot many slightly divergent races or species,
more or less different in their adaptations and
reactions, exposing the very mechanism of
evolution to our view. These phenomena, read
in the light of the remarkable genetic studies on
Drosophila and other insects, begin to acquire
extraordinary significance and interest. It
must further be said, that if we are to take
full advantage of the wealth of biological op-
portunity afforded by the insects, we must turn
to the tropics, where the number and diversity
of species is at a maximum. In the tropics
essentially similar climatic conditions have per-
sisted for ages, permitting the development of
biocoenoses which may be compared with old
and highly diversified civilizations. But the
detection and analysis of these requires resident
study or permanent stations, as the English
naturalist, A. R. Wallace, long ago insisted.
Expeditions, traveling rapidly over the coun-
try, appear more adventurous or romantic, and
often return with very large collections; but
any one who has oceasion to study the speci-
mens so collected, must keenly realize the lack
of biological information.
For all these reasons, the Tropical Research
Station in British Guiana, established by Mr.
Marcu 31, 1922]
William Beebe, is certain to become classical
ground. Not only is the station most favor-
ably situated for research, but it is securing
the interest and cooperation of some of the
most brilliant American naturalists. Although
much work has already been done, it rep-
resents no more than a minute inroad on the
resources of the locality. But whatever may be
accomplished hereafter, it will not often hap-
pen that any more interesting story will be
written than that by Dr. W. M. Wheeler on the
insects associated with the plant Tachigalia.
This genus of leguminous trees has long been
known to harbor ants within the enlarged and
hollowed petioles. The very name of the genus
was derived by Aublet (1775) from the native
name indicating this association. Dr. Wheeler,
in the short time at his disposal, was able to
detect no less than 50 species of organisms
associated primarily with the leaves or terminal
shoots of the plant, or secondarily with the
organisms thus associated. Twenty-eight of
these were ants, half of them representing new
species, subspecies or varieties. The others in-
cluded various kinds of insects, seven of which
proved to be undescribed, and have been dis-
cussed in short supplementary articles by a
number of specialists. The regular or normal
inhabitants of the petioles are certain ants,
beetles and coccids. The ants comprise two
species of Pseudomyrma and two of Azteca.
The coceids are all of one species, identified
as Pseudococcus bromelie (Bouché)!. The
beetles have been described by Messrs. Schwarz
and Barter, of the U. S. National Museum,
and are found to represent two species of
Silvanide, one of them so remarkable as to
be placed in a new genus. The discussion
centers around these beetles, which prove to
have very singular habits. Both adults and
larvee feed on the parenchyma of the Tachigalia
1 Bouché’s description, quoted by Signoret, is
partly inaccurate, and may not refer to a Pseudo-
coccus at all. The current identification of the
species is traditional, and probably cannot be
justified or confirmed. The ‘‘P. bromelie’’
found on pineapples in Florida (Quarterly Bull.
State Plant Board of Florida, October, 1917, p.
47) is almost certainly P. brevipes (Ckll.), and
cannot be Bouché’s species.
SCIENCE

petioles, but they also solicit and drink the
sugary excrement of the coccids. When a beetle
finds a coccid, it proceeds to apply its antenne
to the rounded surface of the mealy-bug’s back,
like “an expert pianist moving his hands from
side to side over the key-board, or a masseur
with his hands in soft gloves, massaging a
patient.” The beetle may spend as much as
forty or more minutes in this operation. If
the coccid is in the proper condition, it dis-
charges a drop of liquid, which the beetle at
once greedily swallows. The beetles do not
seem to be able to judge whether the coecid
is capable of responding, and will work for long
periods without getting any results. Not only
do the adult beetles behave in this manner, but
the larve also solicit food from the coccids.
Dr. Wheeler not only describes the interrela-
tionships of the various insects in considerable
detail, but gives a most interesting discussion
of the general problems of instinet and habit
involved; a discussion which has the advantage
of being based on a minute knowledge of actual
facts, rather than general presumptions as to
what ought to be true. This discussion ends
with a speculative passage which can not fail
to attract the reader’s attention.
“Fouillée believes that every appetition in-
volves a rudimentary cognition and that auto-
matic behavior like that of the habits and re-
flexes is merely lapsed appetition. If it could
be shown that the latter really can have this
derivation and that such ontogenetic mechan-
isms as habits can acquire representation in
the germ-plasm and hereditary transmission, we
might be in a position to give a consistent ac-
count of all animal behavior, and one which
would lead us to regard the reflexes and the
tropisms as ultimate, highly specialized end-
stages instead of primitive, elemental com-
ponents of behavior” (p. 118).
Charles O. Farquharson was trained in the
University of Aberdeen, and went out to Nigeria
as government mycologist. Through Dr. W. A.
Lamborn, entomologist at the same station, he
became interested in insects, and both men were
greatly stimulated by Professor E. B. Poulton
of Oxford, with whom they constantly cor-
responded. Owing to conditions arising out of
the war, Farquharson was obliged to spend
302
much of his time in doing routine work un-
connected with sciences, but he managed to
make a great number of interesting observa-
tions, which he hastened to communicate to
Professor Poulton in letters, along with speci-
mens of most of the species referred to. He
hoped, on returning home, to work up his re-
sults and publish his more important discover-
ies, but he lost his life through a collision
at sea within a few hours of Liverpool. Pro-
fessor Poulton has edited his letters, adding
a brief memoir and numerous notes, together
with a series of contributions, from specialists,
describing many of the new or interesting
species found.
The paper is so long, and its contents are
so varied, that it is impossible to give an
adequate summary. The principal section,
however, refers to the transformations and
habits of a number of species of Lycaenidae,
and brings out a number of new and curious
facts. It is a strange coincidence, that almost
simultaneously with Dr. Wheeler’s publication
of the observation of beetles obtaining liquid
nourishment from coccide in South America,
Farquharson’s account of similar habits in
Lycenid butterflies in Africa appears. The
butterfly concerned is Teratoneura isabelle, a
long account being given, showing that the
attending ants are driven away, apparently
by flapping the wings. Professor Poulton
suggests that an offensive odor is also pro-
duced. Later, two other related butterflies, of
distinet genera, were found to have the same
habits. Unfortunately the coccids were not
preserved, and we can only conjecture that
they were some species of Pseudococcus.
Both of the works reviewed were capable of
being completed only by the cooperation of
rather numerous specialists, entomologists and
botanists. It becomes increasingly evident that
much of the best work in bionomics must
necessarily be cooperative, no single individual,
however learned, being capable of dealing with
all of the species and problems involved. It
is pleasant to find, in the papers before us,
that the desired assistance was freely given
and is completely acknowledged. Only in this
spirit is it possible for men to work harmo-
niously together, and any who fail to conform

SEALING TUNGSTEN INTO PYREX
THE author has spent considerable time in
evolving a good method of sealing tungsten
wire into Pyrex and fastening the copper lead-
wires to the tungsten. The method here des-
cribed is easily accomplished and the freedom
from breakage is certain. It is hoped that the
present detailed description may save others
sufficient time to justify its publication. An
elementary knowledge of glass-blowing is
assumed.
The sealing-in glasses and the order of join-
ing are:
tungsten—G705H—G702P—Pyrex.
The numbers are used by the Corning Glass
Company to designate these glasses. Some
glass-blowers prefer to omit G705H and seal
the tungsten directly to G702P. The G705H
is of lower melting point, may be used in the
gas-air flame and hence offers less chance to
oxidize the tungsten.
Clean the wire by sandpaper only or warm
in the flame, dip in a saturated aqueous solu-
tion of sodium or potassium nitrite (or nitrate)
and then polish with very fine sandpaper or
even the thumb nail. Draw small tubes of
each of the three kinds of glass having an in-
ternal diameter slightly larger than the dia-
meter of the wire. Cut a short length from
each and string them on the wire in the order
(above) in which they are to be sealed. The
flame should be applied first to the middle of
the G705H bead and the others in turn be
brought along the wire and melted to the pre-
ceding one. The wire with its glass coating,
Fig. 1-a, may then be sealed in in the usual
manner but joining Pyrex to Pyrex. In case
the tungsten wire is small and it is desired to
protect it from the flame the Pyrex enclosing
tube may be extended through the final seal,
Fig. 1-b, and the excess glass broken off after
the seal is accomplished.

seal may also be made by squeezing a bead of
G702P in a Pyrex tube but with less freedom
from breakage.
To join copper to tungsten:
(a) electroplate tip of tungsten wire with
copper or nickel and solder (silver solder for
higher temperatures).
(b) melt nickel wire to tungsten in oxygen
flame using borax as flux or even no flux. Nick-
el becomes very brittle and it is best to then
solder to the nickel bead thus obtained.
(c) form are of 10 to 20 amps. between
tungsten and nickel wires to coat tungsten with
nickel; solder.

(d) German silver (for this use of it I
am indebted to Mr. Cummings of the Depart-
ment of Chemistry of this University) flows
much better than nickel. Use method (b) with
borax as flux. Copper wire may be joined at
once in flame just as in joining copper to
platinum.
The method used will generally depend upon
facilities available.

New Texts
CUMMER——-A Manual of Clinical Laboratory Metheds New
N this, the newest book on the subject, clinical laboratory methods are presented in concise
and accessible form. While devoted largely to description of methods, thorough attention
is given to the underlying principles, the indications for performing tests and the significance
of the results. In most chapters the plan is as follows. (1) Outline of routine examinations;
(2) description of the simple qualitative methods which are frequently employed; (3) descrip-
tion of quantitative methods or those of intricate technic ; (4) discussion of findings in vari-
ous morbid conditions. When several methods are given, usually the preferred one is indi-
cated. The method of counting blood cells has been given meticulously, and special atten-
tion has been given to the histology and pathology of the blood. Chemical examination of the
blood and urine and the relations of urine examinations to life insurance are also treated
very fully. The section on Serum Reactions is, in effect a monograph on the Widal, Wasser-
mann and related tests. The liberal use of cross references in the body of the text and the
synoptic résumés of quantitative procedures in the chapters on Blood and Urine greatly facili-
tate the use of the book in the clinical laboratory.
Chapter Headings: Examination of the Blood—Examination of Urine—Examination of
Gastric and Duodenal Contents—Examination of the Feces—Examination of Sputum—Ex-
amination of Body Exudates, Fluids and Miscellaneous Methods—Bacteriological Methods—
Appendix (Equipment, Stains, Vaccines—examination of a large number of specimens, etc.).

MANSFIELD on BOTANY—Developmental and Descriptive New
NEW TEXT by a distinguished authority which, because it deals with the two most in-
teresting phases of botany, will achieve the very desirable effect of securing the stu-
dent’s earnest attention. The text is complete and with a logical arrangement that will ap-
peal to all teachers of the subject and is largely illustrated with photographs from Nature.

KENDALL—Bacteriology, General, Pathological and Intestinal .,, 42
NE of the achievements of the Great War is a noteworthy advance in the Science of
Bacteriology. This is manifested not only in marked improvements in methods of in-
vestigation and in modifications of preéxisting views in the important fields of Infection and
Prevention of many diseases, but also in a complete revision of some of the more important
groups of bacteria. Prominent among these is the great class of anaérobic bacilli. During
the war period, furthermore, much additional information has accumulated pertinent to dis-
eases which have hitherto been elusive. These developments have necessitated the rewriting
of entire sections of this book, and extensive changes and additions to nearly every chapter.
Indeed, including the anaérobes and the work on spiral organisms, this new edition contains
as much as any volume in existence of the worth-while war and post-war work.
The text aa that characteristic which contributed so largely to the success of its first
edition, namely, dynamic interpretation of the subject. The author emphasizes throughout
what bacteria do rather than zwhat they are—how they get into the tissues—what they feed
on—what they excrete—how they multiply—how they escape from the body—the chemistry
of bacterial activity.
New methods of handling bacteria, methods which are improvements over earlier ones,
details of laboratory equipment, the minutize of technic and the use and value of apparatus
are carefully consdered. Much space is given to the discussion of the applications of bac-
teriology in Etiology and Preventive Medicine, as well as Serology and Vaccine therapy.

THE EARLY TRAINING OF
SCIENTISTS
Iv is a strange feature of the modern educa-
tional process that though children are born
richly endowed with scientific instincts into a
world which has gladly accepted a multitude
of gifts from science, they encounter, from the
cradle to the university, constant opposition to
the education of. these instincts.
The child is excellent raw-material for the
making of the scientist. First of all, he is
curiosity inearnate; he does not confine his
attentions to those matters which adults con-
sider practical, but tries to learn all he can
about an environment which he finds brimming
with interest. Moreover, he is an experimen-
talist, and the days are too short for the ex-
periments he wishes to perform upon every-
thing at hand, from the bric-a-bric to the
patience of his elders. He relies upon ex-
periment rather than upon authority for learn-
ing truth. Authoritative representations con-
cerning the fragile qualities of glass, the taste
of pepper or the temperature of a stove are to
him but suggestions for experiments. Although
his experimental technique is simple and his
capacity for reasoning and theorizing are un-
developed, he has made a splendid beginning
towards a scientific career.
In~ his further development, however, he
meets with opposition at every turn. Many of
his experiments earn punishment from his
parents, who discourage his curiosity and even
pervert the truth for their own ends. At
school, book-learning is substituted for observa-
tion and experiment, and even when the topic
is nature or science it is often taught in a very
didactic way by a teacher who, though having
taken many courses in pedagogy, may have but
little appreciation of the spirit and method of
science. At Sunday school he is likely to find
a teacher who praises as religious virtue the
306
docile acceptance of dogmatic authority and to
whom the term “doubt” is one of opprobium.
The repressive process, alas, does not end
here, for we in the university who next take
him in hand delight in giving him the impres-
sion that the subject has been thoroughly elu-
cidated. We take little pains to help him to
realize the existence of vast fields awaiting
exploration. Moreover, we are so anxious to
guard him from errors of fact that we announce
in advance what he is expected to find in his
experiments. He is told to mix solution A with
solution B and “to note the red precipitate
which is formed.” The precipitate he gets may
happen to be yellow, but he has learned by
this time that it is safer to call it red in his
note-book. Why quarrel with the instructor,
it is wiser to give the answer he wants and
keep him in a good humor.
I am convinced of the justice of the fore-
going diatribe, as I have had an intimate
acquaintance with the problem, not only as a
child, a student and a parent, but, I must con-
fess also, as a teacher. Indeed, so thoroughly
convineed have we been in the department of
chemistry of the University of California of
the importance of giving the student, so far as
we can, a real training in the scientific method
and spirit, that we have taken great liberties
with that most conservative of all university
courses, the freshman course in general chem-
istry. So many have asked for information
concerning our methods that I am encouraged
to assume sufficient general interest to justify
an exposition of our attempt at the solution
of this important problem.
We have been inspired by the opportunity
offered by a fundamental course to present
science in such a way as, first, to win for scien-
tifiv careers the keen-minded students who are
repelled by the drudgery and memory work
of the old-fashioned course in descriptive chem-
istry; and, second, to encourage the average
student to adopt the scientific attitude towards
his everyday problems, an attitude so neces-
sary in combatting the superstition, prejudice,
selfishness and dishonesty in the world of or-
dinary aifairs.
Although the following paragraphs ceseribe
a course in chemistry, our aim in giving -+his
SCIENCE
[Vou. LV, No. 1423
course is not simply to teach chemistry, but
through it to teach science. Whether the
student proceeds to advanced work in chem-
istry or enters one of the numerous fields for
which it is prerequisite, or even takes no fur-
ther scientific studies, it is important for him
to have scientific training. The medium for
this training is with us chemistry, but other
subjects can, of course, be taught with a simi-
lar purpose in view.
in order to attain these ends we have been
convinced that the laboratory work must be the
central feature of the course, and that it must
involve the solution of problems rather than the
mere performance of illustrative experiments.
This makes the work harder and therefore more
interesting. The doctrine that the interest of
the pupil is to be gained through ease and
practicality is an educational fallacy. The stu-
dent belies this doctrine in his own practice.
Football is difficult and impractical, but it
arouses far more interest than dishwashing,
which is both easy and practical.
The teaching of elementary chemistry has
been slow to reflect the modern state of the
science, which is no longer chiefly descriptive,
but to a high degree mathematical and de-
ductive. It has largely continued, in the
language of Le Chatelier, to present “une
énumération indéfine de petits faits particu-
liers: Formules de combinaisons, densités,
couleurs, action de tel on tel corps, recette de
preparation, ete.” Laws and principles appear”
to the student as dykes intruding into the mass,
but not fusing with it. While it is difficult
and probably undesirable to abandon altogether
the traditional method, we have sought to sub-
stitute for much of the purely informational
material, a grasp of great principles such as
the atomic, molecular, kinetic and ionic theo-
ries, the mass law, and the periodic system of
the elements, and to make them not mere defini-
tions, but tools to be used with intelligence and
skill. It is of little use for the student to de-
fine the mass law unless he can actually use it
in controlling a new chemical reaction. There
is little point in committing the periodic table
to memory unless he ean apply it with assur-
ance in predicting chemical behaviors.
We have been fortunate in being able to in-
APRIL 7, 1922]
clude general chemistry and qualitative analysis
in one intensive course of two laboratory
periods, two quiz periods, and two lectures per
week throughout the year. It has thus been
possible to minimize the usual break between
these subjects and to develop systematically
from the general principles of chemistry to
their application in the problems of analysis.
In the laboratory manual, written by Professor
W. C. Bray with the assistance of Dr. W. M.
Latimer, the effort has been to stimulate the
student, through proper experiments; first, to
gain a working conception of the atomic the-
ory, the molecular theory and the behavior of
gases. There follows next, a study of acids and
bases and of titration, in order to develop and
apply the idea of concentration. A further
study of acids, bases and salts leads to the
ionic theory. In this connection we have not
considered it necessary to discuss an element
at length before studying one of its compounds.
Acetic acid, for example, is a quite familiar
substance, whose acid properties may be in-
vestigated before studying organic chemistry,
and it is not necessary to diseuss sulfur, sulfur
dioxide and the manufacture of sulfurie acid
in order to do some laboratory work with the
acid. There follow assignments on strong and
weak acids and bases and the uses of indica-
tors to measure the concentration of hydrogen
ion; rapid reversible reactions and equilibrium;
the reversibility of neutralization reactions, or
hydrolysis; the properties of sodium, potas-
sium and ammonium ions and the tests for
sulfate and nitrate ions; the chemistry of
calcium ion, developing solubility equilibria and
the transformation and solution of precipi-
tates; carbonic acid, carbonate and bicarbon-
ate ions; the salts of copper, sulfur and zine,
which prepare the way for the study of com-
plex ions, amphoteric hydroxides and the im-
portant reactions utilized in qualitative anal-
ysis.
Unknown solutions of increasing difficulty
are introduced during this period, but more |
emphasis is placed upon the student devising
methods of analysis than upon committing to
memory and using the orthodox schemes, which
few chemists ever use in actual practice with-
SCIENCE
307
out appropriate short-cut modifications. Oxida-
tion and reduction reactions and electric cells
are next introduced, followed by a study of
ions whose separations involve oxidation and
reduction.
The effort is made constantly to throw the
student upon his own responsibility, especially
in observing accurately and in drawing general
conclusions from his experiments. There are
numerous questions calling upon him to pre-
dict results of untried experiments.
The lecture work is organized to supplement
closely the laboratory work and to contribute
an element of stimulus and inspiration. The
topics in the early part of the course are taken
up in much the same order. When acids, bases
and salts are introduced in the laboratory, the
lectures take up the alkali metals followed by
the alkaline earth metals. The chemistry of
the metals is so much simpler than that of the
non-metals that we have been more than satis-
fied by our abandonment of the usual order of
presentation in which the halogens are intro-
duced early in the course. An intensive study
of the periodic system and its use in predict-
ing and correlating not only physical proper-
ties but chemical characteristics as well, con-
tinues throughout the year with necessary in-
terruptions from time to time by other topies.
A reference book has been written for the
course in which the aim has been to present
clearly and briefly the principles of chemistry.
The topics have been arranged in convenient
order for reference rather than as in the lec-
tures. The program of the lectures can thus
readily be altered from year to year to try ex-
periments of instruction, and making it easier
to avoid the stagnation so fatal to even the best
of courses.
~ But though general principles are emphasized
in the teaching, we feel that the final test should
not be the statement of the theories but their
application. In our examinations, therefore,
we usually say little about theories and prin-
ciples, asking the student rather now to pre-
pare one salt from another; how to accelerate
or retard given reactions; how to shift certain
equilibria; how to dissolve various precipitates;
whether he would expect a given acid to be
308
stronger or weaker than another, or a certain
salt to be more hydrolyzed than another; what
properties of substances make them useful for
certain purposes.
The suecess with which the more intelligent
students are able to answer such questions has
convinced us of the efficacy of this form of
instruction. The students seem also to grasp
something of the enthusiasm and interest in
the science of chemistry which turns some of
them ultimately into capable research workers.
We have noted with considerable satisfaction
moreover, that even the more purely descrip-
tive type of chemistry is rather readily learned.
It is evident that the habit of correlating facts
with each other and with theory has made the
assimilation of the information comparatively
easy. ‘
In order to achieve its object such a course
must have the advantage of contact with the
more advanced work and the research carried
on in the department, and must be taught by
men interested in discovery. It has been our
policy, therefore, for all members of the de-
partmental staff to take part at more less fre-
quent intervals not only in the weekly confer-
ences of instructors, but also in the laboratory
and quiz sections. This practice has been ef-
fective in unifying the purposes of all the de-
partmental courses. The junior assistants are
all candidates for the Ph. D. degree, and hence
actively engaged in research. The better stu-
dents are frequently invited to see the work
these graduate assistants are carrying on in the
research laboratory, which proves a source of
considerable inspiration.
Thus beginning with students from the high
school, many of whom have not had even high
school chemistry (for we admit students if they
have had high school physies and trigonometry),
we are able to accomplish in a single intensive
course what is ordinarily extended over two
years; and by continuing the same intensive
method in the more advanced courses, to pre-
pare the student for serious research at the
beginning of the senior year. The large pro-
portion of students who go on into graduate
work and the output of the laboratory in re-
search are evidence of the rich fruit of the
SCLENCE
[Vou. LV, No. 1423
method. We are confident also that those stu-
dents who have studied elementary chemistry
as preparation for some allied science have
received a far better training for their later
work than a more purely informational course
could afford.
JoEL H. HILDEBRAND
ARE IODIDES FOODS?
Ir has been considered by some biologists
and chemists that living matter originated in
the sea and the elements of living matter cor-
respond to those found in the sea water. We
might look, therefore, to the composition of
sea water for the elements we should expect to
find in living matter. Sea water consists
largely of H,O and sodium chloride, and be-
sides those the chief ingredients are magne-
sium, calcium, potassium and carbonates, sul-
phates and bromides, but there are also present

in a large number of animals and Gautier?

are familiar with the fact that fluorine is a
regular constituent of bones and teeth and
iodine of the thyroid gland. In experiments
on the nutrition of animals, I have found it
very convenient to feed them evaporated sea
water and in this way insure a supply of all
the rare elements. Cameron and Carmichael®

iodide in preventing goiter in sheep and in
preventing the hairless pig malady is quite
well known. The use of iodide in the treat-
ment of goiter was first brought out by the
work of Dumas, who was born in 1800 and
studied pharmacy in Geneva. Dumas and
Coindet found that iodine was valuable in the
treatment of goiter. The use of sodium iodide
in the prevention and cure of goiter was
strikingly emphasized in 1917 by Marine and
Kimball. This leads to the natural conclusion
that the cause of goiter, or at least one of the
causes, might be the lack of iodine in our diet.
Iodine seems to be very rare in food and soils
(Private communication of Oswald Schreiner)
or else the former methods of detection have
not been sufficient for such traces as do exist
(See Kendall and Richardson® for later meth-
ods). Iodine has been found in a number of
rocks such as slates (Gentile®), limestones
(Lembert’), dolomite (Rivier and Fellenberg®)
and granites (Gautier) in Europe and has
been reported in vapor from Vesuvius (Mat-
teueci®), but it seems to be leached out so rap-
idly from soils it is seldom to be detected.
Forbes?® failed to find iodine in about half of
the specimens of foods, and Cameron" had a
similar experience. The question of the rela-
tion of goiter to locality has caused much dis-
cussion and most persons have come to the
conclusion that goiter is due to the presence
of some substance rather than the absence, but
since much fruitless work has been done in
the attempt to find this substance it would be
well to investigate more thoroughly the ques-
tion of the absence of some substance.

Goiter occurs largely in mountainous regions
or regions far from the sea. Iodine is so rap-
idly leached out of the soil that the supply of
it may depend upon salt spray blown from the
sea. During storms the waves are broken into
a spray and the water evaporated and the salt
carried for long distances through the air. This
salt is washed down out of the air by rains
and contaminates the rain water. In the

is shown a map of the eastern states, indicating
the relative amount of sea salt in the rain
water. Determinations were made by the
weight of a certain constituent (the chlorine
ion) by the ordinary silver nitrate titration,
but sea water is of very uniform composition
in regard to everything except H,O. That is
to say, when the salts are diluted or concen-
trated, they are all changed in the same ratio,
and the dry salt would be of uniform com-
position, so that the chlorine titration would
indicate the relative amount of iodine. Evap-
orated sea water contains 50 parts per million
of iodine, whereas the chlorine forms 55 per
cent. of the evaporated sea water. The lines
on the map indicate parts per million of
chlorine in the rain water and the iodine would
be about one ten-thousandth of this amount,
or, in other words, a part per million of chlo-
rine would be about a part per ten billion of
iodine. We can say, therefore, that the
amount of iodine in the rain water rapidly
deereases as we go from the coast, and is least

the goiter as reported by the Draft Board and
we have more or less the same distribution in
the opposite direction and see more goiter
towards the lake region and less toward the
coast. Owing to the fact that no chlorine maps
have been made for the rest of the country, it
is not possible to extend this comparison. It
is reported, however, from various sources (and
is my personal observation in Minnesota) that
the whole Great Lakes region is quite goiterous,
and this is necessarily a region in which very
little sea salt falls upon the land since the air
blowing over it has already been washed free
from sea salt by previous rains. Besides this
goiterous region, various mountainous regions
in the country have been reported to be goi-
terous and this is also true of Europe. These
mountainous regions may be relatively near
or far in relation to the sea. We often speak,
however, of the clear mountain air free from
dust, and it seems very probable that sea salt,
being very heavy, would tend to remain in the
lower strata of air rather than rise to mountain
heights. Voleanic dust when thrown to great
heights may remain in the upper air for a con-
siderable time, but this is true only of the very
finer particles of dust. The larger particles
settle very rapidly. In fact, so rapidly as to
sometimes bury towns. We may suppose the
same things are true of the sea salt in the air.

[ Vou. LV, No. 1423
The very finest particles may be carried to
greater heights than the larger ones, provided
they can escape the rain long enough to reach
that height in the first place. The voleanic
dust is thrown rapidly to the great height. The
sea salt is thrown into the air at the sea level
and its reaching a great height is very for-
tuitous. Therefore, we may suppose that the
oceurrence of goiter in mountainous regions
fits in with the deficiency hypothesis. The ab-
sence of iodine from the rain water and soil
in a region would necessitate its absence from
the plants growing in the region and the ani-
mals subsisting entirely upon the plants and
rain water. Man, however, may receive con-
siderable food from some distance. Food rich
in iodine, such as fish, oysters, squid, sea-
hares, sea urchin ovaries and sea weed, is con-
sumed to a much greater extent along the sea
coast than in inland regions. Sea weed is not
a general article of diet and is only eaten
habitually by the Japanese and certain other
peoples living close to the sea. Sea food,
owing to its perishable nature, is largely con-
sumed close to the sea. Therefore, even with
considerable means of food distribution, the
relation of goiter to distance from the sea
might still be maintained. Water might hold
the same relations. Water flows toward the
sea and therefore does not bring iodine from
regions richer in it. Water courses rise either
in mountainous regions or in inland lakes
which are goiterous regions. Certain mineral
springs may be exceptions but the consump-
tion of such mineral water is rather limited.
The principal other factor in the diet is salt.
Salt was first obtained by the evaporation of
sea water. The process used reduces the
amount of iodine, but the extent of reduction
may depend upon the amount of refining that
the salt undergoes. The sea water is evap-
orated in shallow ponds until the caleium ear-
bonate precipitates. It is then further evap-
orated in other ponds until the sodium chloride
crystallizes out. The mother liquor from the
sodium chloride crystals, known by geologists
as the bittern, contains most of the iodine
along with magnesium chloride and other salts.
This erude sodium chloride, which may have
some iodine clinging to it, was formerly con-
APRIL 7, 1922]
sumed in this condition but nowadays is often
further purified by washing and reerystalliza-
tion so that the iodine, which is in very low
concentration in the sea water, is reduced to
infinitesimal quantities. Salt was not purified
to as great an extent in the early days as it is
now. When it comes to rock salt Nature has
already purified it to some extent. Van’t Hoff
showed the mechanism of stratification of the
rock salt deposits. The sodium chloride layers
are already more or less purified. This salt
when it is mined in the dry state or when it is
obtained from salt springs, which consist of
water which has come in contact with these salt
deposits, is still further purified for table use.
Hayhurst'! investigated some of the salt works
in Ohio where the salt is obtained from deep
wells. Bromine and a trace of iodine are sep-
arated out of the salt and the bromine sold as
a by-product.
I have been unable to obtain any evaporated
sea water, that is to say, salts obtained from
the sea water without fractional precipitation
or purification, from any commercial salt
manufacturers on the coast. Through the
kindness of Metz & Company, Dr. Sherndahl
evaporated 100 gallons of sea water for me to
use in experimental feeding. This, together
with sea water which I have had opportunity
to evaporate, has been dried by baking it in
an oven. When the last traces of water are
eliminated in this way, hydrochlorie acid fumes
are also given off. The cause of this, as point-
ed out by Sorensen, is a reaction between mag-
nesium and the other salts whereby oxides of
the alkaline earth metals are formed with the
elimination of hydrochloric acid. If the baking
is continued long enough no calcium or mag-
nesium chloride remains and therefore the salt
remains dry. If the sea water has been evap-
orated in an iron kettle some iron oxide is
added to it, which improves it from a nutritive
standpoint. The necessity of baking may be
eliminated by adding 6 grams of H,PO, to the
liter and this salt may aid in the treatment of
rickets. In my animal experiments this evap-
orated sea water has been used for generations
of animals as the salt ration, with gratifying
results. It is very low in phosphorie acid
14 Hayhurst, E. R., Science, 1921, liv: 131.
SCIENCE
361
unless H,PO, has been added, and if casein is
used as the protein there is not sufficient phos-
phoric acid in the casein for the nutritional
requirements. The question as to whether
there is sufficient calcium or not for the total
calcium ration has not been definitely settled.
If wheat flour is used for the carbohydrate
portion of the ration there is sufficient addi-
tional calcium in the wheat flour to bring the
calcium up to the requirements.
The question arises whether it would not be
advisable for us to feed our children an im-
pure salt. If iodine is the only mineral con-
stituent that might be deficient it could be
easily added to the salt. We have not proved,
however, that the other mineral constituents of
sea water are not necessary in the diet. There-
fore, it would seem much simpler to use evap-
orated sea water as the salt ration if it could
be obtained, and it only remains to create a
demand for it. The present process of com-
mercial evaporation of sea water could be
simplified if an impure salt was desired. That
is to say, only one pond would be necessary
for the evaporation of the sea water. Sea
water could be evaporated in this pond as far
as practical by the sun. The total contents of
this pond, including both solids and liquids,
could then be removed and evaporated by heat
and thoroughly mixed, and baked at a high
enough temperature to produce a dry salt. In
case the erystals of salt were large, owing to
the slow evaporation at first, they could be
ground. In baking, however, there is a ten-
dency for these crystals to break up. The
inclusion of a little earth with the salt would
not impair its nutritive qualities and the
product would be sterilized by the high tem-
perature used in baking. It has been shown
that salt obtained by the usual methods from
the salt evaporating plants on the French coast
is reeking with bacteria. The production of a
sterile product might be an advantage. The
dietary salt of several adults, children and
infants has been limited to the above described
from Metz for many months with gratifying
results, in a goiterous region.

GEOGRAPHY AS A PROFESSION
INTRODUCTION
Mopern geography is a young science, and
usually college students know little of its con-
tent. If they think of it at all, it is usually as
a subject which they were forced to study when
young, but sloughed off when they became men.
They do not recognize that the causal element
now stressed so strongly has given it a content
which has placed geography in the university
curriculum and added greatly to its practical
worth.
RELATION TO OTHER SCIENCES
’ The first point to appreciate is that a liking
for geology, physics, biology, mathematics, as-
tronomy, history, economics, anthropology, or
ethnology, excludes no one from becoming a
geographer. Geography is not an isolated
science. It is an intensively interlocking com-
bination of other sciences directed towards a
broad, but specific field of study. The great
war, if it has proven anything, has proven that
geography and its ramifications present prob-
lems worthy of the keenest and best trained in-
tellects of the day. The fact that geography is
now understood to be of value in settling dis-
putes between new states, in understanding the
possibilities of commerce open to this nation’s
newly created merchant marine, and in inter-
preting to the advantage of all concerned the
prides, prejudices, and virtues of those with
whom foreign trade does or may bring close
contact, has added greatly to the prestige of
the science and those professing it.
OPPORTUNITIES IN GEOGRAPHY
Several types of employment are open to the
geographer. The following list is not ex-
haustive, but suggests the major opportunities
offered.
1. The government now recognizes as never
before the value of trained geographers. There
ean be little doubt but that its need of such
men will increase.
2. Map-publishing houses must
skilled geographers.
3. Great corporations, commission houses,
and banks, as the United States expands its
foreign trade, are recognizing more and more
employ
SCIENCE
[Vou. LV, No. 1423
the necessity of having trained geographers on
their staffs. Certain banks have found it nec-
essary to establish their own schools in order
to give adequate geographic training to men in
whose charge they wish to place their foreign
branches.
4. Although the world is commonly thought
of as pretty well explored, the facts are that
many large areas even on our own continent
are known only very superficially. Skilled
geographers are needed to accompany scientific
exploring expeditions, and with the increasing
need of tropical products, the demand for such
men will increase.
5. Men can not take advantage of the pre-
ceding opportunities without adequate training.
At this present moment, universities are hand-
leapped in giving this because of the lack of
trained teachers. The supply by no means
meets the demand. The student who prepares
himself to teach university geography is taking
advantage of one of the best opportunities in
the entire pedagogical field and rapid promo-
tion is certain for him if he deserves it.
TYPES OF INVESTIGATION POSSIBLE
The main types of investigation possible are
as numerous as are the sciences allied to geog-
raphy, with almost innumerable subordinate
lines under each. A study of the table of con-
tents of a half dozen leading geographical jour-
nals at home and abroad will give some idea of
their variety. Within their covers will be
found studies of all phases of weather and
climate, of the physics of the atmosphere, of
map-making and map-interpretation; explana-
tions of the distribution of the races and lan-
guages of man, and of the relations between
man and his natural surroundings; discussion
of why some countries are great and others
weak; accounts of exploration; reasons for the
courses and materials of trade; and the whys
and wherefores of the surface of the land and
the bottom of the sea. This is just a hint of
the variety of interesting, instructive, and
profitable studies which come to the geographer.
COMPENSATION
Few geographers will become rich. The de-
sire for wealth can never be the compelling
APRIL 7, 1922]
}
reason for entering this subject any more than
others. There are, however, varied reasons why
a young man may well consider it as a life
pursuit.
1. Vigor of body is the natural reward of
the active geographer. This needs no amplifi-
cation.
2. The geographer is brought into intimate
contact with many lines of human interest and
endeavor. Soils, crops, commerce, landscapes,
weather, all kinds of natural resources, both
developed and potential, interest him. And, if
he travels, as he must to progress far in his
science, he gains an insight into the hearts of
men and nations second to none. The geog-
rapher becomes in reality a “citizen of the
world” with much power to promote interna-
tional understanding and good-will.
3. The modern science is young—younger
even than its sister science, geology. Two im-
portant results follow:
(a) The opportunities for employment are
numerous. Those who enter the subject now
are on the “ground floor” as it were, in a
movement which promises to be of much edu-
’ cational and economic importanee.
(6) The opportunities for original discov-
eries and contributions are great. With their
accomplishment comes the reward which the
consciousness of having added to human knowl-
edge always brings. The full power of this
needs to be experienced to be understood.
There is also the additional satisfaction which
comes from being a pioneer in the development
of new aspects of an important subject.
These advantages are on the whole quite sim-
ilar to those of geology. In this connection, it
may be interesting to know that while numer-
ous men enter geology from other subjects, few
leave it—and of those who do, by far the larger
number change into this closely allied science,
geography. The application of the broad learn-
ing of many years to a study which opens
unlimited possibilities for bringing to man-
kind material prosperity, mutual good-will and
friendly understanding, is intensely fascinat-
ing to the maturing man who feels a eall to
serve humanity, yet desires to labor and in-
vestigate in his chosen fields of science. Any
SCIENCE
363
young man who has seriously thought of scien-
tifie work as an attractive life profession must
find in geography an appeal which merits his
careful consideration.

NATIONAL RESEARCH COUNCIL
VIENNA
WHILE in Vienna last summer I was like
other visitors deeply impressed with the
supreme importance to the world of the prob-
lem of relieving this sadly stricken capital. At
that time the exchange rate for the Austrian
crown was about 600 to the dollar and it has
since fallen to a rate of 10,000 to the dollar.
The average salary of the professional man
even six months ago was only the equivalent
of between $100 and $200 a year, and the
recent financial panic has brought the intel-
lectual worker to straits which are almost
beyond belief.
There are, it seems to me, three reasons why
the situation in Vienna makes a unique appeal
to the professional men and women of America.
In the first place the actual suffering is far
greater in Austria than in any other country
outside of Russia. In the second place, there
is at stake here not only the life and health of
individuals but the life of a civilization, one of
the most liberal and enlightened in the world.
The universities and schools of Vienna have
for centuries been the eastern outposts of the
intellectual life of western Europe and in
music, in medicine, and in many other arts and
sciences her contribution has been unrivalled.
In the third place, a peculiar responsibility
rests upon America in this connection because
the recent panic would have been entirely pre-
vented if the congress of the United States had
not delayed for six months the passage of the
foreign debt funding bill which was essential
to the carrying out of the Ter Meulen plan for
the financial rehabilitation of Austria.
We can take great pride in what has been
done by the American Relief Administration,
the American Red Cross and the Friends Relief
Mission to mitigate the suffering of the people
of Vienna. . With the passage of time, how-
ever, it is natural that the enthusiasm of
364
service should somewhat relax. It is important
to remember that the situation is if anything
to-day more critical than ever, and that the
year 1922 will probably determine whether
Vienna shall survive or perish as a center of
intellectual and artistic life. I am therefore
venturing to ask if you will not print the en-
closed extracts from a letter just received from
Miss Hilda Clark of the Friends Relief Mis-
sion, who has just returned to Vienna after a
visit to the United States. I have personally
no connection with the Friends Service Com-
mittee but I admired the work they were doing
in Vienna beyond measure and I can assure
the readers of Science that gifts of money or
of clothing sent to the American Friends
Service Committee, 20 South 12th Street, Phil-
adelphia, for the use of the professional men
and women of Vienna will accomplish a service
of unique value for humanity and civilization.

EXTRACTS FROM MISS CLARK’S LETTER
I am interested to find, on getting back here,
that the worst effects of the financial collapse of
last autumn have not yet begun to show, at any
rate, among the majority of the working-class
population. Unfortunately, the reason for this is
one which no one dares to think can be more than
temporary. It is, that wages have boldly been
put up, and in many trades, have almost risen to
follow the increased cost of living so that people
are actually better off than they were two years
ago.
This applies particularly to food. The situa-
tion in regard to clothing is rather curious. Even
in those trades where the rise in wages has been
greatest, the fluctuation in prices is so uncertain
that any article of clothing, for which it is neces-
sary to save from week to week, is likely by the
time the necessary money to buy it has been
saved, to have doubled in price. You will see
what a strong discouragement this is to people
to save, and how impossible they feel it. Really,
the home maker is in much the same diffi-
culty as the manufacturer, and the working
man or woman has not always the intelligence to
cope with it. This tends to make people, espe-
cially, of course, the more thoughtless, even if
earning the best wages, spend their money on
SCIENCE
[Vou. LV, No. 1423
food each week, rather than save it for clothing.
I do not think anybody would quite understand
and sympathize with them who has not been, to
some extent, in the same position.
Fortunately, the expenditure on food does, after
all, help to restore the physique of the workmen,
which had got so very much undermined before
this rise in wages took place, but it creates a
great deal of misapprehension on the part of
social observers in the town whose first idea is
that the working people are much better off than
they really are.
This would not matter, were it not that there
appears to be no hope at all that the present
wage level can be maintained without causing a
great increase in unemployment. It is not
thought that industry can stand the present cost
of production, as Austria has only obtained her
markets, during the past year, by being able to
undercut other manufacturers. It seems inevita-
ble that she will go through the same phase of
unemployment as has occurred in other countries.
To meet this, she has at present absolutely no
resources except a very uncertain amount of
savings made by the most successful of the war-
profiteers.
Perhaps one should add to her assets the extra-
ordinary courage and grit a great proportion of
the people are showing, and the energy with
which they are turning to the increase of their
home food production. Unfortunately, a good
deal of capital is required to carry this out to a
sufficient extent to enable her to tide over an
industrial crisis, but the amount of capital needed
is very much lessened by the energy and hard
work which the men themselves are giving.
First of all, they have increased the allotment
garden production, and having nearly all the
land that can possibly be reached by the people
living in the present houses in Vienna, they are
moving out to live in the country close to, and
building houses with their own hands to live in
while they cultivate the land. In this way, their
labor is not withdrawn from the industries which
are still working, and if there is temporary un-
employment, they will be ready to return when
conditions improve.
I think it is important that people should
realize that to provide capital for this increase of
the home food production is the only way of
averting absolute starvation if unemployment on
a large scale should occur, even if this were only
temporary. There is no reason to suppose that
industry here could not recover directly condi-
APRIL 7, 1922]
tions in Europe generally improve, or that Vienna
would not be able to take her place on equal
terms with other countries without the advantage
of a cost of production subsidized by foreign
relief.
With regard to the actual physical condition
of the people at the moment, especially of the
children, in which the people who have so gen-
erously helped in America are naturally most
interested, thanks to this increase in wages, which
has kept the majority of the working class from
coming on our hands for relief, we have been
able, with our limited programme, to do what
was necessary to save the lives of the children,
so far, this winter.
In the middle-class, where rises in salary, and
fixed incomes have not come anywhere near the
increase in the cost of living, the suffering is very
terrible, and increasing as the colder weather
sets in; we are now in the grip of a snowstorm
which makes life almost impossible for people
who have not been able to buy either clothing or
fuel, and whose food has been reduced to about a
quarter of that needed to maintain their vitality.
The professional classes here have few children,
and have had hardly any since the war, so that
the relief for young children, which is our main
piece of work, does not very much help them.
We have, therefore, turned our attention very
specially to them this winter, and are particu-
larly increasing, as far as our funds will allow,
the help for the young children between the ages
of 14 and 18 who, even if given one meal a day
by the American Relief Administration, and only
a very few of them get this now that the num-
bers have been reduced, are really not able to
keep body and soul together while they are train-
ing themselves to earn their living.
The students in the university are still getting
some help from the World’s Student Christian
Federation, but this, unfortunately, is coming to
an end, and it is terrible to think what will
happen, if they are unable to continue it, as the
position of the students is certainly worse than it
has ever been.
We are specially turning our attention to the
lower grade or trade colleges of a lower standing
than the university, and which are not included
in this student relief,—where a great many of the
poorest of the professional classes are trying to
.get their boys and girls trained for work which
will enable them to earn their living more quickly
than they could if they had to take the whole
university course. We are now helping nearly
SCIENCE
365
500 in this way, providing a fortnightly ration
‘of extra food, enough to give about a third of
the minimum calory requirements for an adult,
and are also dealing with the whole family, who
are often found, after individual investigation, to
be in the most pitiable plight. All these families
have had a ration of clothing averaging from six
to ten garments per person, towards which they
pay a trifling sum, which covers overhead ex-
penses, and other help has been given where it
was felt that the family could be placed in an
independent position.
The students selected for help have been gen-
erally those in their final year, as it is found
that this is the time when they tend to break
down from the strain of combining study and a
job, in the attempt to earn their keep. We are
hoping to double the number, but if only we could
obtain the funds we ought to increase it to 2,000
or 3,000.
At present, the need for clothing is, perhaps,
the most pressing general requirement. We do
not, of course, need to raise funds for those in
receipt of the best wages, even though they are
in the difficulty I described in the beginning of
my letter, but it must be remembered that the
great majority are still only in receipt of wages
that will barely provide the minimum food for a
family, and have absolutely nothing to spend on
clothing, and in the professional classes, this is
universally the case. They are faced with losing
their jobs because they have not got the clothes
in which to stand, and the bitter weather now
upon us is, of course, making the need tenfold
more urgent.
People may feel that it is now too late to
send clothing for this winter, but if you are able
to make it known how great the need is, I hope
you will not let people be discouraged by the
idea that it may be too late, because people
require clothes to wear in the summer, and par-
ticularly in the case of underclothing, we did not
find last year, that the demand was greatly less-
ened at the end of the winter.
SCIENTIFIC EVENTS
MEXICAN ARCHEOLOGY!
Av a meeting of the Royal Anthropological
Institute on November 22, Mrs. Zelia Nuttall
gave an account of recent archeologocal investi-
gations in Mexico. As an introduction to her
report, Mrs. Nuttall referred briefly to the fact
1From Nature.
366
that after a period of quiescence of some cen-
turies the great voleano Popocatapetl had
again become active in 1920, and that its
activity still continued.
During the last decade evidence that great
voleanic disturbances had taken place at long
intervals has been forthcoming. Two distinct
types of figurines have been found in conditions
which indicate that the topography of the valley
has been changed and its inhabitants destroyed
by great catastrophes antedating the arrival of
the Nahuas or Aztecs.
Of these figurines the first, provisionally dis-
tinguished as the sub-gravel type, was brought
to Mrs. Nuttall’s notice in 1920, when specimens
were offered for sale by Indians, and she herself
discovered an example in sitw under a gravel
bed at Atzacapotzaleo. They were delicately
fashioned of fine clay, with slender bodies, long
faces, smooth-hanging hair, some wearing chap-
lets. All presented a worn and polished sur-
face. In the Valley of Mexico the gravel beds
extend under the lava flow at the base of the
extinct voleano Ausco. ;
Under the lava bed, to which Dr. Tempest
Anderson assigns an age of at least 20,000
years, Mrs. Nuttall in 1908, and afterwards
Senor Gamio, head of the Department of Arch-
eology of Mexico, have discovered a second type
of figurine, to which the name “sub-lava type”
has been given. This type is characterised by
turbans and eaps, evidently of fine stuffs or fur,
and decorated with circular ornaments of stone
or shell. They indicate that the southern part
of the valley was inhabited by a race totally
distinct from that of the “sub-gravel type” and
the Aztec. The distribution of the clay figurines
is now under investigation. They have been
traced as far as Guatemala.
Mrs. Nuttall also described the results of re-
cent excavations at Teotihuacan, during which
a small pyramid was opened up and recon-
structed by Senor Gamio. A tunnel pierced at
the height of 35 feet to the center of the pyra-
mid revealed that it had been formed of mud
filled with innumerable fragments of pottery
vessels which had prevented the mud from
eracking when it baked in the sun. A remark-
able discovery was that of the remains of the
SCIENCE
[Vov. LV, No. 1423
ancient pyramid temple with a wonderful sculp-
tured frieze which had been partly destroyed
and then concealed by another terraced pyramid
temple built in front. The sculptured serpents’
heads and the masks of the water-god Tlaloc
are of a form hitherto unknown. Associated
with them are sculptured shells, principally the
conch shell and the pecten or pearl shell. Not
only is it remarkable that sea-shells should be
represented in sculpture in the heart of the
continent, but the association of the water-god
with the ocean is entirely new.
In the discussion which followed Mrs. Nut-
tall’s paper, Mr. Maudslay expressed the hope
that it might be possible before long, by the
elaboration of a system of stratification, to date
Mexican antiquities. As Mexico appeared to
have been untouched by outside influence, the
study of its antiquities afforded evidence of the
highest value for the study of the development
of the human mind acting by itself. Mr. T. A.
Joyce emphasized the importance of the evi-
dence relating to the figurines, and pointed out
that the British Museum had acquired a figurine
of similar technique from Eeuador. Professor
Eliot Smith expressed the opinion that, con-
trary to what had been stated by Mr. Maudslay,
Mexican antiquities showed clear evidence of
influence from outside and in particular from
Asia. Mrs. Nuttall’s work showed that this
culture must have crossed the Pacific.
THE ROYAL AGRICULTURAL SOCIETY OF
ENGLAND
Tue council of the Royal Agricultural Soci-
ety of England has, as reported in the London
Times, unanimously adopted a report from the
chemical committee of the society, which had
been instructed “to consider in what way, in
view of the altered circumstances, the scientific
side of the society might be developed.” The
council afterwards appointed the following
research committee to carry out the research
proposals made by the chemical committee:
The Duke of Devonshire, Lord Bledisloe,
Professor W. Somerville, D.Se. (Oxford), Mr.
Dampier Whetham, F.R.S. (Cambridge), Mr.
Henry Overman, and Mr. John Evens, with
Mr. Charles Adeane (chairman of the finance
APRIL 7, 1922]
committee), Mr. J. L. Luddington (chairman
of the chemical committee) and Mr. C. Colt-
man-Rogers (chairman of the botanical com-
mittee) as ex officio members.
The chemical committee recommended that
the society should form a fund definitely re-
served for research, into which payments
should be'made as funds allow. The following
paragraphs summarize their proposals:
(a) That the results of the past experimental
work of the society should be collated, abstracted
and published. i
(b) That the society should continue to devote
part of its scientific energies to agricultural re-
search, and should at once establish a separate
fund for its support.
(ce) That members of the society be invited to
make suggestions as regards practical problems
which they consider require experimental investi-
gation.
(d) That members of the society be invited to
cooperate, by the provision of land, stock, ete., in
carrying out such work.
(e) That scientific institutions as occasion
arises be asked to aid the society in the elucida-
tion of problems that can not be dealt with on
an ordinary farm.
(f) That a research committee of eight mem-
bers be set up, to review proposals and to ini-
tiate and supervise experiments.
(g) That the research committee should submit
to the council in November estimates for the
forthcoming year’s work, and in March a report
on, and the audited accounts for, the work of
the last year.
(h) That arrangement be made at once for the
publication of past experimental results, and that
experiments be initiated as soon as possible.
The committee points out that the society
has successfully undertaken a large amount
of valuable and varied experimental work,
not only at Woburn, but elsewhere, and
results of much service to agriculture have
thereby been secured. The work has included
the manuring of crops and grass, green manur-
ing, sowing down land to grass, the quality of
seeds, finger and ‘toe in turnips, the treatment
of farmyard manure, cheese making, the fat-
tening of cattle, sheep and pigs, and the rear-
ing of calves. The results are reported in the
Journal, but, although available, are not con-
venient of access. The committee believes that.
SCIENCE
367
farmers and students would benefit greatly if
the society would issue, in at least two volumes,
one dealing with crops and the other with
stock, the experimental results it has achieved.
A substantial fee would have to be paid for the
work, but there should be no difficulty in find-
ing a firm who would relieve the society of any
financial responsibility in respect of publica-
tion.
The committee holds that further experi-
mental work is vital to the interests of the
society. For “research without reference to
utilitarian ends” the society is not fitted, either
in respect to technical equipment or’ of per-
sonnel; but it is eminently quality to undertake
research which deals directly with problems
that arise in practice. Its members consist
largely of practical farmers with long experi-
ence of the land and of the difficulties and
problems of its cultivation.
At the moment the committee suggests that
the following questions might well engage the
society’s attention:
(a) The value of ground mineral phosphates,
more particularly in the improvement of pasture.
(b) The use of various forms of lime on grass
and tillage crops.
(c) The use of wild white clover, wild red
clover, bird’s foot trefoil, ete., in laying land
down to grass.
(d) The profitable utilization of whey.
MOLDING SANDS
Tue Committee on Molding Sand Research
under the guidance of Division of Engineering,
National Research Council, and the American
Foundrymen’s Association, has made progress
in its program of research. The United States
Geological Survey and the various state geolog-
ical surveys have promised to cooperate with
the sub-committee dealing with this phase of
the work under the chairmanship of Professor
H. Ries, of Cornell University. This sub-
committee has prepared a letter of instructions
to the state geological surveys, which will
standardize methods of making the surveys of
molding sand resources.
Work on standardization of tests is well
under way. Questionnaires have been sent out
to gather information on the present methods
of testing physical properties of sand. A
368
digest of replies to these questionnaires is ex-
peeted to be available shortly.
Many firms and universities have offered to
cooperate in the research work. Every en-
deavor will be made to maintain their interest
and to assign problems to those universities
and industrial laboratories offerimg to co-
operate; due regard being given to the facili-
ties and talent available. A list of research
subjects has been compiled, which is given in
part below:
1. Recovery of used molding sand through re-
storing bond to the sand by subjecting it to con-
tact with water vapor under high pressure.
2. The effects of additions of certain chemical
reagents upon the physical properties of clays
and clayey materials, such as molding sand.
3. Effects of water content on the bond and
permeability of a molding sand.
4, Effects of different water per cents. in mold-
ing sand on the milling and drilling speeds of
light gray iron castings.
5. Research on fusion quality of facings (fune-
tion of ‘‘peeler’’).
6. Tests of various kinds of clays for restoring
bond to molding sand.
7. Comparison of the life of different molding
sands.
8. Effects on plasticity of bond in molding
sand and reduction of water content when using
oil.
9. Effects of wet and dry storing of sand on
bonding quality.
The American Steel Foundries Company has
permitted a representative of the committee to
make a digest of the sand reclamation work
carried on by the engineering staff of the
A. S. F. and has assisted in the preparation of
this digest. Because of the scarcity of steel
molding sand of the best quality and the prob-
lems arising from having to dispose of large
quantities of refuse sand, this company has
carried out an extensive investigation of meth-
ods of reclaiming the good material which is
usually lost, whenever the so-called refuse sand
is thrown away. After experimenting along
different lines and thoroughly going over meth-
ods employed in other plants, a process of
reclaiming old sand ealled “centrifugal serub-
bing” was developed.
SCIENCE
[Vou. LV, No. 1423
After establishing the principle of this
method, equipment was designed which permits
a recovery of about 70 per cent. of refuse sand.
Cost figures for 1921 show that a ton of re-
claimed sand costs about $1 per ton against
the cost of new sand, at the plant, of $2.65 to
$3.85 a ton. The process involves cleaning the
sand grains of adhering fused material, then
separating by air currents the good sand from
the bad material. Included in the 30 per cent.
loss is some good bonding material which, be-
cause of its similarity to bad material, can not
be economically separated.
The report covers the theory of sand reclaim-
ing, centrifugal air scrubbing process, cost of
reclaiming sand by the latter process, and a
description of the proposed sand reclaiming
unit.
THE BRITISH INDUSTRIAL FATIGUE RE-
SEARCH BOARD
THE second annual report of the Industrial
Fatigue Research Board has recently been
issued. As reported in the British Medical
Journal it contains “a comprehensive summary
of the chief results obtained by the board since
its inception some three years ago. These re-
sults have been published in a series of sixteen
reports, which represent the output of the
board’s investigators over a period of about
two years, for there is necessarily a consider-
able delay before the results of the inquiries
reach the stage when they are ready for pub-
lication. If any critie had doubts as to the
value of the board’s work, and the importance
of its further development on the lines laid
down in this report, we think that such doubts
would speedily be laid to rest by an impartial
study of its pages. They contain a solid body
of information which is of direct value to em-
ployers of labor, and to welfare workers and
factory inspectors; the practical application of
this information to the remedy of adverse
industrial conditions would produce a very real
improvement in the health and efficiency of the
workers. In the analysis of published work
with which the report opens the various tests
of efficiency and fatigue employed are briefly
described, and then a more detailed account is
given of the results obtained in various indus-
Aprin 7, 1922]
tries concerning output in relation to hours of
labor and the duration of work spells and rest
pauses. A subsequent section of the report
deals with the impersonal physical conditions
of the worker’s environment, such as tempera-
ture, humidity, ventilation and lighting, and
the effects of these conditions on efficiency.
Personal factors, such as vocational selection
and guidance, time and motion study, and the
effects of such conditions as seating and cloth-
ing, are treated in considerable detail, whilst a
shorter section deals with such matters as or-
ganization and the relative importance of
human and mechanical factors in efficiency.
Most of the sections are illustrated by diagrams
reproduced from the published reports of the
board, and they show at a glance the hourly
and daily variations of output observed under
various conditions, the effect of regular rest
pauses on output, the improvement of output
caused by more adequate lighting and by better
ventilation, and the value of certain psycho-
physiological tests in measuring the skill of
compositors. The future of the board is said
to be full of promise, for, in addition to the
investigations already made in certain branches
of the textile, iron and steel, and boot and shoe
industries, others are now in progress in the
laundry and the pottery industries, whilst ap-
plication has been made to the board by various
trade boards and research associations for the
institution of inquiries into several other im-
portant industries.”
THE MEDICAL FELLOWSHIPS OF THE
NATIONAL RESEARCH COUNCIL
As reported briefly in Scimncx last week, the
National Research Council has established fel-
lowships in medicine created for the purpose
of increasing the supply of thoroughly quali-
fied teachers in medicine in both clinical and
laboratory subjects and in both curative and
preventive aspects. The fellowships are sup-
ported by appropriations of the Rockefeller
Foundation and the General Education Board
amounting in total to one hundred thousand
dollars a year for a period of five years. Those
receiving awards will be known as fellows in
medicine of the National Research Council.
To qualify for appointment as a fellow, a
SCIENCE
369
candidate must have the degree of doctor of
medicine or doctor of philosophy from an ap-
proved university, or preparation equivalent
to that represented by one of these degrees.
Only citizens of the United States or Canada
will ordinarily be appointed, although the fel-
lowship board is authorized to set aside this
provision in exceptional eases. The fellowships
will be open to both sexes.
Since the principal purpose of establishing
these fellowships is to increase the number of
competent teachers in the field of medicine,
each incumbent will be required to gain experi-
ence in teaching. As creative work is regarded
as essential to the best teaching, emphasis will
also be placed upon research.
Fellows will be at liberty to choose the insti-
tutions or universities in which they will work,
as well as the men under whose direction they
will carry on their researches, subject to the
approval of the fellowship board.
Appointments are to be made for a period of
twelve months, beginning at any time in the
year, with an allowance of six weeks for vaca-
tion. The time may be extended, however, if
in the judgment of the board the work which
the fellow has done justifies it. The stipends
are not definitely fixed in amount; but they
are intended to enable the individual to live
comfortably while carrying on his special work
as a fellow.
The fellowships will be administered by a
special committee, known as the Medical Fel-
lowship Board of the National Research
Council.
Correspondence concerning the fellowships
should be addressed to the Division of Medical
Sciences, National Research Council, Wash-
ington, D. C.

Baskerville Hall. (2) The founding of a fund
to provide for a medal to be called the Charles
Baskerville Prize and to be awarded each year
to the student doing the best work in chemistry.
(3) The establishment of a scholarship to per-
mit students who qualify to pursue courses in
advanced chemistry. Subscriptions to the fund
should be sent to Professor W. L. Prager of the
college.
WE learn of the death on March 19, ab Los
Angeles, California, of Mrs. Martha Burton
Williamson, long a prominent figure in that
city, a contributor to the conchological litera-
ture of the Pacific Coast, and the donor of a
large collection of shells to the Los Angeles
City Museum. She had been for many years
vice-president of the Historical Society of
Southern California.
Dr. Brensamin Moors, Whitney professor
of biochemistry in the University of Oxford,
and formerly professor of physiology at Yale
University, died on March 3, at the age of
fifty-five years.
Dr. Aucustus D. Waturr, professor of
physiology and director of the physiological
laboratory of the University of London, died on
March 11, at the age of fifty-five years.
THE death is announced from Paris, at the
age of 84, of the dean of French mathema-
372
ticians, Camille Jordan, member of the Aca-
démie des Sciences, professor emeritus at the
Collége de France and the Ecole Polytechnique.
He will be particularly remembered for his
“Traité des substitutions,” which appeared in
1870 and is still to-day the great classie in the
theory of finite groups for his “Traité d’Ana-
lyse” and especially for his editorship of the
Journal de Mathématiques in which he followed
Resal in 1884, guiding its destinies until this
very last year. He had the intense satisfac-
tion of seeing it recently saved from extine-
tion, most probably owing to the strong sup-
port that it received from America.
Proressor Dr. THEopor LirsiscH, late pro-
fessor of mineralogy at the University of Ber-
lin, died at his home in Berlin on February
9, after a protracted and painful illness. A
correspondent writes: “Liebisch was born on
April 29, 1852 and from about 1890 to 1900
he was professor of mineralogy at the Univer-
sity of Gottingen. During this period there
were many Americans studying for the doc-
tor’s degree with their major in chemistry.
Most of these men took mineralogy under Pro-
fessor Liebisch as one of their minors, and it
is hardly too much to say that he was one of
the most highly respected and best loved pro-
fessors in the university. He perhaps did more
in a personal nature for the American students
in those days than did any other professor.
All Americans respected and admired him for
his deep learning, his ability as a teacher, his
inspiration for research work and his extremely
kind and ever-thoughtful nature. About the
year 1900 he was called to the University of
Berlin, and served there until about 1920, when
he retired from active work. He was the
author of many books, his most important be-
ing “Grundriss der Physikalischen Krystallo-
graphie.”
A Gzorcia ACADEMY OF SCIENCE was or-
ganized on March 25 by a group of twenty-
two scientific men, invited to the University of
Georgia for that purpose. The delegates came
from Emory University, the Georgia School of
Technology, Mercer University, Oglethorpe
University, the University of Georgia and the
SCIENCE
[Vou. LV, No. 1423
Georgia Experiment Station. Practically all
phases of scientific endeavor were represented.
Membership in the academy is to be a recogni-
tion of noteworthy service to science or to the
scientific development of the state, and the num-
ber is limited to fifty. It is the aim of the
academy to foster every means of encouraging
scientific research, to develop the natural re-
sources of the state, and to stimulate in the
people a realization of the fact that their pros-
perity depends very greatly on the scientific
training of a large number of Georgia men.
THe Sigma Xi research fellowships for the
coming academic year will be awarded in May.
Applications should be made to Professor Ed-
ward Ellery, Union College Schenectady, N. Y.
The awards are made for work in sciences
other than physics and chemistry and to men
and women who have already taken their doe-
tor’s degree. Applications should be accom-
panied by reprints of published articles and by
reference to two or more persons competent to
speak about the ability of the candidate in his
or her special line. The minimum award is six-
teen hundred dollars.
Dr. Witiu1am Crocker, director of the
Thompson Institute for Plant Research, ad-
dressed the Brooklyn Institute of Arts and
Sciences on March 25 on “The present outlook
for plant research in Europe.”
Dr. W. J. Humpureys, of the U. 8. Weather
Bureau, recently lectured before the West Vir-
ginia University Scientific Society on “Fogs

DISCUSSION AND CORRESPOND-
ENCE
GENETICAL ANALYSIS AND THE THEORY
OF NATURAL SELECTION
In my Toronto address I lately referred to
John Ray as the first who laid stress on the
sterility of interspecific hybrids. I was then
writing away from books and must apologise
for this slip. The passage in the Historia
Plantarum 1686, 1, pp. 40 and 42, that I had
in mind is probably the first in which anything
approaching a genetical definition of species
is attempted. Ray there lays down the excel-
lent principle that forms which, though differ-
ing from each other, can be bred from seed of
the same plant, should be regarded as of the
same species. Not till the Linnean period,
more than half a century later, did the cognate
question of the sterility or fertility of inter-
specific crosses assume prominence.
Professor Osborn has expressed great vexa-
tion at the tenor of my address. After con-
sidering his remarks, I do not know that I can
add much to what I have said. The diver-
gence between the conceptions to which genet-
ieal analysis introduces us and the doctrines
SCIENCE
373
of which Professor Osborn has been so long
a distinguished champion is indeed wide.
Paleontological observations have served a
useful purpose in delimiting the outline of
evolution, but in discussing the physiological
problem of interspecific relationship evidence
of a more stringent character is now required;
and a naturalist acquainted with genetical dis-
coveries would be as reluctant to draw conelu-
sions as to the specific relationship of a series
of fossils as a chemist would be to pronounce
on the nature of a series of unknown com-
pounds from an inspection of them in a row of
bottles. The central tenet of Darwinism that
species are merely the culminations of varietal
differences, such as we find contemporaneously
oceurring, is not easily reconcilable with the
new knowledge. It was my purpose once more
to direct the attention of naturalists, espe-
cially geneticists, to this deficiency in the evi-
dence, by no means without hope that it may
be supplied.
Professor Osborn, in extenuation, suggests
that my tongue ran away with me and that I
could not have meant what I said. That de-
fense, however, is not available, for I had taken
the precaution which I understand he learned
from Huxley, and I had prepared a written
text. This, in all important passages, I fol-
lowed verbatim, and it appears without serious
modification in Science for January 20. I
may even plead guilty to having spoken and
written to the same effect on many previous
oceasions, and Professor Osborn will find the
theme developed in ‘Problems of Genetics”
(New Haven, 1913, and in my presidential
address to the British Association in Australia
(1914).

A SUGGESTION TO MR. BRYAN
I THINK most readers of Sctnncre must feel
indebted to you as I do for reprinting W. J.
Bryan’s attack on Evolution. It may be true
that only the psychologists will be able to find
in it data of value to their science but to them
the importance of this contribution of Mr.
Bryan’s must be large indeed. The rest of us
welcome the diversion which it affords. A Don
374
Quixote of Mr. Bryan’s calibre only appears
once or twice in a century and the opportunity
to study in cold print the celebrated Nebras-
kan’s proposal to resurrect the “special erea-
tion of species’ myth must be appreciated by
our scientific. brethren who are interested in
studying the mysterious ways in which the
human mind sometimes works when it ap-
proaches subjects unfamiliar to it.
My principal object in writing you is to
suggest that Mr. Bryan should be invited to
use the pages of Science to attack an even
greater heresy than Evolution. Since Mr.
Bryan still gets his biology from the Bible it
appears to be a safe inference that he must
draw his geography from the same source.
Bible geography, or “flat geography” is, I am
informed, taught nowadays only in the moun-
tains of eastern Tennessee. Why should not
our Bold Knight from Nebraska (or is it
Florida?) aim his lance at the teachers of
modern or “round” geography and admonish
them to hark back to the geography of Joshua?
This is perhaps a subject which has been over-
looked by this eloquent defender of Biblical
science. I can hardly believe it to be lack of
courage which has led Mr. Bryan to attack
the few and widely scattered teachers of evo-
lution instead of the thousands of teachers of
modern geography. Whatever the explanation
of Mr. Bryan’s neglect to denounce the heresies
to be found in the textbooks on geography
may be, I beg to suggest that the heretical
character of the modern teaching in geography
should be brought to the notice of Mr. Bryan.

THE WRITING OF POPULAR SCIENCE
To tHE Epitor or Science: Both Dr. Al-
fred H. Brooks! and Dr. Edwin E. Slosson*
have recently called attention to the fact that
relatively few popular scientific works are be-
ing now written in this country; and the form-
er expresses the opinion that there is to-day
relatively less popular knowledge of science

[ Vou. LV, No. 1423
and less interest in its methods and advance-
ment than there was a generation ago. This
opinion will probably be generally accepted as
correct. That it should be true in spite of the
large amount of scientific work that has been,
and is being done, and in spite of the serious
attempts of scientific associations and other
agencies to create a popular interest in science,
indicates that it is high time for scientists to
consider seriously themselves, science and thw
public, in an endeavor to ascertain wherein the
difficulty lies. Most scientists will agree with
Dr. Brooks that the lack of popular knowledge
of science is directly due to the form in which
science is presented, and that “what is needed
is the presentation of science in a form com-
prehensible to the educated and thinking man.”
But to secure such presentation, it is necessary
to understand the public, the point of view of
those we desire to reach, the mental background
with which the science we present must be
harmonized; to understand science and our-
selves; to keep in mind what constitutes
science; to have a clear idea of what we wish
to give the public. Otherwise we are in danger
of merely groping blindly, and of, perhaps
often, prostituting the name of science.
We all acknowledge that science is organized
knowledge. That neither an isolated fact, nor
an infinite number of isolated facts, is science;
no matter how true and exact the facts may
be. It is only when two or more facts are seen
to be related, that science comes into exist-
ence. Science does not consist of facts, but of
recognized relations between facts. Science
is essentially a mental phenomenon®.
But are there not, only too often, offered
under the guise of science mere isolated facts
trimmed with sufficient allegory and super-
ficial analogies to fill a respectable amount of
space and to attract the layman’s attention?
This is not science, but merely information—
the raw material out of which science is made.
3 Since this was written’ Dr. F. L. Hoffman’s
admirable vice-presidential address (ScIENcE,
Mareh 10), entitled ‘‘The Organization of
Knowledge’’ has come to my attention. In this,
the essential distinction between mere facts and
science is strongly emphasized.
APRIL 7, 1922]
It has no cultural value other than what the
reader can supply by coordinating it with other
information that he has aequired from other
sources. Only by, and to the extent of, such
coordination does the fact become scientific.
Is it not here that the scientist needs to con-
sider both himself and his reader? For him,
this fact he offers has a wealth of associations,
he sees it in its relations to numerous other
facts; the mere fact that this particular fact
is, has for him far-reaching implications; it
is against such a rich and harmonious back-
ground that he sees the fact. But with the
layman it is far different; he can furnish but
a meager background, often merely a dead
black drop. The fact as presented with its
allegory and analogy may appear to him very
beautiful, or wonderful, or surprising, but it
does not mean anything to him. Is it sur-
prising that he does not enthuse over it? A
person likes to feel that he is getting some-
where. An article that establishes a recog-
nized relationship between two or more facts
meets this desire, and by the serious minded
public would surely be received more favorably,
‘than one that merely retails information.
But the choosing and presenting of a rela-
tion between facts is difficult. The scientist
is embarrassed by the complexity of the rela-
tions that he recognizes; what portion of the
vast web shall he choose? And having chosen,
how can he supply the proper surroundings
to give it in any fair degree its true signifi-
cance when seen against the drab background
that will be furnished by the reader? To
sueceed, he must know how to present his facts
and arguments so that they will fit into his
reader’s experiences and habits of thought.
He must be acquainted with his reader. Is it
not here that the great difficulty les? The
scientist of this country seldom has the leisure,
and often has not the inclination, to become
really acquainted with the experiences and the
mental processes of the non-scientist. As a re-
sult, he is unable to present his scientific knowl-
edge in a form that is readily understandable
by the layman.
The remedy is to be found in a more intimate
acquaintance of the scientific and the non-
SCIENCE 375
In the en-
deavor to secure such improved acquaintance,
the scientist is called upon to take the initiative,
and to do the most. He must cultivate the aec-
quaintance of the non-scientist; must study
scientific classes with one another.
him; must show him, in a way that he can
understand, what science really is; must make
him see that scientific work dves not consist in
merely collecting wonderful, interesting, or
surprising facts and observations, nor. in in-
venting useful or weird contrivances, but in
ascertaining how facts are related to one an-
other, so that he may be able to forecast with
confidence the results that will follow from a
given act, and conversely, may be able to speci-
fy what set of acts will give a desired result.
The non-scientist must be made to see that
science does not consist in making inventions,
but in furnishing the raw materials out of

and the securing of their interest in science
and its advancement will cease to be a problem.
The public ean learn what science is, only
by being shown properly labeled examples of
it. These must be understandable, but never-
theless must be real and rigid science; and
in no case should the reader be relieved of all
necessity for thinking. Among the types of
subjects that appear to be suited to this pur-
pose are: (1) Accounts of discoveries, in which
the reason for undertaking the work and the
main steps in the establishing of the conclusions
are given. (2) Accounts of experimental re-
search, or of precise measurement, in which
the line of reasoning, illustrations of check ex-
periments, ete., are given. (3) Accounts of
experiments designed to established suspected
relationships between observed facts. Un-
suecessful experiments should not be ignored.
(4) Accounts of the establishing of relation-
ships between observed facts by purely in-
ductive methods.
Tf we would avoid giving the public a false
idea of what science really is, let us discour-
age the practice of placing the label “science”
on presentations of mere isolated facts, and let
us clearly inform the public, by word as well
as by example, that science consists in the es-
376
tablishing of relations, not in the cataloguing
of facts.

THE EARNING POWER OF RESEARCH
A FEW years ago the X-ray tube was an er-
ratic apparatus not in any very general use.
The research laboratory of the General Electric
Company realized that there was a possibility
of utilizing pure electronic emission from a hot
filament to produce controllable X-rays in a
perfect vacuum. They conducted extensive re-
search upon such devices as then existed, and
as a result the tungsten target took the place
of platinum in the standard gas tube of that
day. Research had also to be applied before
the laboratory learned positively that available
electrons already existed and that there was a
possibility of controlling them, as, for example,
focusing them on a target. The research has
been continued, until today practically all the
X-ray tubes of the country are made by the
company in accordance with the discoveries of
the man whose name the tubes bear. The
Coolidge tube is also used abroad almost to the
exclusion of other types. These remarkable
results have been achieved through very care-
ful, accurate, and often discouraging studies
of electric phenomena in high vacua, with very

accessories and generating apparatus used in
X-ray work, of from five to ten million dollars
a year. The benefit cannot be measured wholly
in monetary return, for everyone is familiar
with the humanitarian benefits.
Our oldest industries have been the most re-
luctant in establishing research laboratories.
But the experience of a leader may guide the
entire industry. Some years ago the Ward
Baking Company established a fellowship at
the Mellon Institute. The research soon
brought results and the application of a more
balanced yeast nutrient to the dough gave
better fermentation and better bread. It was
discovered that the baker can grow yeast in the
dough and control fermentation wastes. This

conservation amounts to 2 per cent of the flour,
15 per cent of the sugar, and sufficient yeast
to make the total saving 45 cents net per bar-
rel of flour used. It is estimated that this
process saves American, Canadian, and Brit-
ish bakers not less than $40,000 per day, with-
out detriment to the quality of the bread.
In 1915 a control laboratory was installed
with one chemist. Today there are a variety
of control laboratories with twenty-five tech-
nical workers. A chemist has frequently saved
two months’ salary for his employer with a
report on samples from a single carload of
butter. The control which has been established
as a result of research upon the raw materials
makes possible uniformity in the finished
product. Time, temperature, and other fac-
tors which influence fermentation have been
established, and since no two carloads of flour
are alike the data are vital in determining how
fermentation must be varied to secure uniform-
ity. The study of enzymes, proteins, colloids,
yeasts, bacteria, and nutrient value is pointing
the way to still better bread, higher nutritive
values, economy in production, and the eleva-
tion of the entire industry. It is no wonder that
during these days of industrial depression this
pioneer in research as applied to baking has
increased the number of its scientific workers.
Results continue to justify the increase.—The

shorter papers which have supplied the- first
adequate account of the free ecrinoids. It has
been no mean task, for when Mr. Clark tackled
the problem, the classification of the comatulids
was in a state of hopeless confusion. The reso-
lution of this chaos into a system was a brilliant
piece of analysis and construction, and consti-
tutes a notable achievement in the field of ani-
mal taxonomy. The present volume contains
an enormous amount of detail, and maintains
the high standard of Part 1. It has a wealth
of illustration—no less than 1,364 figures, the
greater part drawn by the author, as there are
few photographs. Such figures as have been
taken from previous authors have in almost all
cases been retouched by Mr. Clark to bring out
points previously overlooked or misinterpreted.
Nine hundred forty-nine drawings appear in
the text.
What might be termed the background of the
work has been stated by Mr. Frank Springer
in his review of Part 1, and need not therefore
be recounted here. The present volume con-
tains a very large amount of entirely new and
original matter. It begins by taking up the
description of the radials of the comatulids at
the point at which it was left at the end of
Part 1. The articular faces of the radials of
52 species are described in detail from dissec-
tions preserved in the collection of the National
Museum and reference is made to the 20 de-
scribed more or less satisfactorily by previous
authors. The whole subject of the structure,
relationships, physiology and homologies of the
socalled post-radial structures (arms and pin-
nules) is exhaustively treated. All of this
matter is original and is based upon specimens
in the National Museum. The perisomic plates,
or those developed within and entirely confined
to the ventral surface, come in for detailed de-
scription for the first time, the subject being
handled in an entirely new way; and the side-
plates and covering-plates of the pinnules of
203 species in the National Museum collection
are also treated.
A complete and detailed account of the an-
atomy, embryology, and regeneration of the
comatulids is given. There is at present no
single source from which this information can
SCIENCE
377
be derived, as it is widely scattered through a
great number of usually short papers in various
languages.
The spawning season of 24 species is given;
previously that of only 4 species was known.
The pentacrinoid young of 28 species are de-
scribed and the first comparative account of the
pentacrinoids is given.
A considerable amount of information is as-
sembled concerning the habits, reactions to
various stimuli and food, concerning which up
to the present there has been no adequate source
of information.
All of the numerous parasites and commen-
sals on the crinodis are listed and when neces-
sary for comparative purposes, many of those
occurring on other echinoderms. Parasitism
and commensalism among marine invertebrates
has been greatly neglected and this section
therefore forms an important contribution to
the subject. Incidentally, a detailed account
of the myzostomes, almost exclusively parasitic
on the crinoids, is given, together with a com-
plete list of all the known species. No other
list exists at present.
The coloring of the comatulids, remarkable
for its brillianey and diversity, is treated in
detail for the first time, the color of 160 species,
in many eases from the author’s own notes
taken at sea, being given. The pigment is
described and the chemical composition of the
skeleton is discussed.
Such, in bare outline, are the contents of an
extraordinarily well conceived and thoroughly
executed treatise, upon the publication of
which the author as well as the authorities of
the National Museum.are to be congratulated,
for the work will always remain a point of
departure for future investigation.
The press-work of this volume is excellent
and an improvement over that of Part 1. The
half-rag paper is also a decided advance, al-
though really too thin to carry the larger text
figures, since the printing on the reverse shows
through. A few copies of such fundamental
memoirs as the present should be printed upon
heavy, full-rag paper, or better still upon linen,
and deposited in, say, half a dozen “strategie”
libraries of the world. Too many of our basic

monographs are printed upon paper which will
be relatively short-lived.

A NEW VARIETY OF BARLEY WITH STRI-
KING CHARACTERISTICS
Tue new variety of barley, which the writer
has provisionally called Mack’s Branched bar-
ley, has never been recorded in literature here-
tofore. It was discovered by Mr. J. M. Mack,
of Fallbrook, California, in a wheat field mixed
with much barley. Specimens of the new form
were sent to the University of California in
1921 for further investigation; and the writer
has been much interested in it in connection
with his genetic studies in barley. It is a six
row barley possessing the following character-
istics:
1. An Increase in the Number of Nodes
accompanied by an irregular Shortening of
Internodes. The number of nodes in ordinary
varieties of barley varies from three to seven,
the uppermost internode below the spike be-
ing always the longest; while Mack’s Branched
barley has from 10 to 30 nodes on each tiller
without elongation of the uppermost internode.
The shortening of the internodes and the in-
crease in the number of nodes make the straw
much stiffer; and indeed the variety would be
most resistant to lodging if not for the fact
that too heavy a weight is carried at the upper
portion as a result of branching.
2. The capacity to Branch at Any Node.
Tillers arise from the first node at the bottom
in ordinary cultivated barleys. Wessling bar-
ley has a branched spike, but the branching
is confined to the head. No form has been re-
corded heretofore as branching freely at any
node and also capable of secondary and terti-
ary branching, which is a characteristic of
Mack’s Branched barley.
3. The capacity to Produce Roots at any
Node. Although it is possible to induce some
of the common varieties of barley to produce
roots at nodes near the base, the setting of

SCIENCE
[Vou. LV, No. 1423
roots at the upper nodes when covered with
soil is quite a unique character, possessed by
this form alone.
4, The Capabilitay of Vegetative Propaga-
tion. The fact that this variety of barley is
capable of branching and rooting at every node
suggested to the writer the possibility of vegi-
tative propagation. Abundant roots were se-
cured by the layerage method in a period of
2 weeks in the open field in January. Cutting
off a tiller and transplanting it in a pot in the
greenhouse has resulted in slower recovery
than in the case of mount layerage; but never-
theless a main root has arisen from a node near
the place of cutting and hence it is reasonably
sure that the cutting will succeed as a separate
plant.
The possibility of vegetative propagation of
this cereal is of considerable scientific interest,
if it is not yet of practical agricultural interest.
This new form is of appreciable value especi-
ally to those interested in genetic studies of
barley, because it makes possible the continuous
propagation of the heterozygote. This will
make backerossing in barley as a means of
genetic investigation more practical, although
it is still doubtful whether backcrossing can
be extensively employed in this cereal, the pro-
cess of artificial fertilization being so tedious
in contrast with the ease of growing self-fer-
tilizing hybrid generations.
Although the new form is apparently of no
agricultural value by itself, yet the branching
and cold resistant characters may be utilized
to advantage by hybridization with some of the
commoner types of cultivated barley.
Nothing is yet known concerning the origin
of this interesting form, as it was discovered
in a mixed field. All that we know is that its
striking characteristics are constant and breed
true under the different environmental con-
ditions to which it has been subjected. The
writer plans to make a number of crosses be-
tween this form and several of the cultivated
varieties in the coming spring, as this interest-
ing barley certainly deserves an intensive
genetic study.

THE FEDERATION OF AMERICAN
SOCIETIES FOR EXPERIMENTAL
BIOLOGY
Tue Federation of American Societies for
Experimental Biology, which comprises the
American Physiological Society, the American
Society of Biological Chemists, Inc., the Amer-
ican Society for Pharmacology and Experi-
mental Therapeutics, and the American Society
for Experimental Pathology, met for their
annual scientific program, December 28-30,
1921, under the auspices of Yale University.
Two joint scientific sessions were held. The
first joint session was called at 9:30 on the
morning of December 28 under the presidency
of Dr. J. J. R. Macleod of the Physiological
Society. Twelve scientific papers representa-
tive of the research work of the four societies
were presented and discussed at this session.
An equally strong joint session was held at the
close of the third day, beginning at two o’clock
on December 30 and consisting of eleven
papers. Sessions of the individual societies
filled the remaining four periods of the meet-
ing.
The executive committee of the Federation is
composed of the presidents and secretaries of
the four constituent societies as follows:
J. J. R. Macleod, executive chairman; C. W.
Greene, secretary; D. D. Van Slyke, C. W. Ed-
munds, F. G. Novy, V. C. Myers, E. D. Brown
and Wade H. Bown. The first executive com-
mittee meeting was called at 4:30 p.m., Decem-
ber 27, at which time the following business
was transacted. The report of the treasurer
of the Information Service Fund, Dr. Joseph
Erlanger, was presented showing a net balance
of $312.34. The secretary of the Information
Service presented the annual report showing
progress during the year. This appointment
service undertakes to call to the attention of
universities and scientifie institutions and
others the availability of scientists in the dif-
ferent technical lines represented by the soci-
eties. The late Dr. S. J. Meltzer, who keenly
appreciated the difficulties confronting the
young men preparing in science in the way of
securing information of openings in _ their
lines, and the equal difficulty met by institu-
SCIENCE
379
tions in finding men of scientific preparation
and fitness in particular lines, contributed the
original fund to meet the expenses of this
activity. It is the hope of the Federation that
increasing use of this institution will be made
through the secretary, Professor E. D. Brown,
of the University of Minnesota.
The problem of correlation of overlapping
programs as between the Federation and the
American Association for the Advancement of
Science, together with the desirability of hold-
ing periodical joint meetings, was presented
and discussed. Such cooperation was favored
by the Federation. Informal discussion was
had of the necessity of the appointment of a
permanent secretary to care for the increasing
general business of the Federation. This was
referred to the incoming executive committee.
The most important act of the Federation
was the presentation and discussion of a reso-
lution calling attention to the decreasing sup-
ply of young men entering the pre-clinical
medical sciences. The general discussion tend-
ed to show that aside from the effects of recon-
struction activities, there are certain special
causes operating to deter young men from
choosing the biological sciences even though
attracted by their intrinsic interest.
It was recognized that there is always the
need of giant personalities and great teachers
who stimulate and lead young men by an
attractive presentation of the science itself.
However, the financial advantages and the
secondary rewards of a professional career too
generally outstrip the financial income and
perquisites of research and teaching in the
biological sciences. Scientific investigators do
not expect great financial returns but they do
have a right to sufficient income from their
activities to avail themselves of the usual jour-
nals, meetings, and other necessary instru-
ments for scientific work. The standards of
maintenance of the. social and family position
of the scientist and the education of his chil-
dren are well defined. Many teachers hesitate
to urge upon their brilliant students careers
which do not of themselves guarantee this
degree of support. The net result is that it
takes an idealistic temperament with a cer-
380
tain amount of utopianism to adopt as a life
work scientific professions which involve so
much of sacrifice to person and family.
In recent years also there seems to be a
tendency in educational and scientific institu-
tions to break away from the recognized paths
blazed by the trained and conservative leader-
ship of those who have made the present
standing of the basal medical sciences in
America. It is admitted that academic ruts
may become established which may possibly
best be eradicated now and then by drastic
innovations. But the question is raised whether
the rewards of promotion in rank and of ealls
to institutions of recognized leadership have
not too often been made on the basis of some
special demand which for the time being has
swayed the control in these institutions. The
break in morale is the same in science as would
occur in business or military organizations
when awards fall too frequently outside the
groups of seniority in leadership and scientific
attainment.
The executive committee after confirmation
by the constituent societies approved and
passed the following resolution with instruction
that the same should be published and by other
means called to the attention of administrators
and others responsible for scientifie appoint-
ments in American institutions.
RESOLUTION OF THE FEDERATION OF AMERICAN
SOCIETIES FOR EXPERIMENTAL BIOLOGY
Adopted December 30, 1921
The Federation of American Societies for Ex-
perimental Biology, comprising the American
Physiological Society, the American Society of
Biological Chemists, Inc., the American Society
for Pharmacology and Experimental Therapeutics,
and the American Society for Experimental Path-
ology, as the official body representing workers in
these various fields, feels that it is its duty to
call the attention of the authorities of our univer-
sities and endowed foundations, of the medical
profession and others, to the grave situation now
existing in respect to recruits in these branches
of biological and medical science.
1. A country-wide investigation, recently pub-
lished, has revealed that the number of young
men of ability entering on careers in the sciences
basal to medicine and surgery is inadequate to
fill the available positions.
SCIENCE
[Vou. LV, No. 1423
2. This condition is due to two factors:
a. The number of positions in the preclinical
sciences in universities and other institutions has
increased more rapidly than the number of men
entering these fields; and
b. The improvements and increased opportuni-
ties for laboratory investigation in clinical sub-
jects, together with the greater remuneration in
clinical departments, have made such positions
relatively more attractive. In response to the
urgent demand for men of scientific training to fill
clinical posts, many are becoming clinicians who
under former conditions would have remained in
the preclinical sciences. With the increasing
growth of scientific medicine it becomes evident
that the only clinical teachers and investigators
competent to carry forward modern medicine are
those who have had sound training and experience
in one or more preclinical sciences and have later
acquired clinical skill and judgment.
3. The great contributions to knowledge and
human welfare which the sciences represented in
this Federation will make, is to be determined by
the number of able workers in these sciences. An
adequate application of physical sciences to
biological and medical problems will come only
from the broadest development of physiology,
biochemistry, pharmacology and pathology; and
the aid of these sciences in the progress of clinical
medicine will largely depend upon the ability of
these departments in our universities to supply
the basic training to those who later enter upon
clinical work. They must therefore furnish the
recruits both for their own laboratories and for
the clinics; failure to do so will prevent the
progress now underway.
The Federation submits these facts to the
thoughtful consideration of university authorities,
and strongly recommends that immediate efforts
be undertaken to improve the status and facilities
of the basal medical sciences, so as to increase
the number and ability of the recruits drawn to
these sciences.
The cordial invitation of the University of
Toronto to hold the next annual meeting of the
Federation in the halls of that institution was
accepted and it was ordered that the annual
meeting for 1922 be called at the University of
Toronto, Toronto, Canada, December 28-30,
1922.

Mathematical Philosophy

By CASSIUS J. KEYSER, Ph. D., LL.D.
Adrain Professor of Mathematics,
Columbia University
Tuese “lectures for educated laymen” aim at
democratizing science and scientific criticism. They
show that the greatest of mathematical ideas—the
pillar-concepts of the science—belong no more to
mathematics than to all science and to rational
thought in general. The great pillar-concepts are
explained in the simplest terms. The reader need
not be a mathematical specialist. The lectures are
not addressed primarily to mathematical techni-
cians. They are designed for students and teach-
ers whether of mathematics or philosophy or en-
gineering or psychology or logic or education or
sociology or art or natural science and for all
other students, thinkers and critics who own alle-
giance to the laws of thought and who desire to
gain a fair understanding of the nature, the spirit,
the standards and the bearings of the science
which Plato called divine.

PSYCHOLOGY AS A CAREER?
PsycHo.oey is the science which deals with
the nature of human and animal behavior and
with the direction of its forces from the point
of view of mental life.
There are as many words in the dictionary
with mental connotation as with physical.
There are as many mental phenomena subject
to scientific study as material phenomena. The
mental sciences may in the near future have as
many branches and embrace as large scope as
the material sciences.
As out of the pure physical sciences have
come engineering, medicine, architecture, and
other forms of applied material sciences, so in
the near future will come the applications of
psychology to education, medicine, industry,
art, and all other varieties of human endeavor
in which scientific knowledge of human or ani-
mal behavior can be made of practical value.
The opportunities for a career in mental
science will, in the near future, be as numerous
as in the material sciences.
No science is more intimately and practically
related to the conduct of human life than is
psychology. It is, indeed, concerned primarily
with those facts and principles of experience
and action upon which our understanding of
ourselves as conscious beings and our ability to
understand and sympathize with our fellows
depend.
PurE PsycHOLOGY
As now taught in the best colleges and uni-
versities, psychology is presented in several
fairly differentiated courses. Ordinarily there
is one general introductory course of one year
furnishing a general survey of the subject from
1 This article is one in a series published from
the various divisions in the National Research
Council under the general topic, ‘‘Opportunities
for a Career in Science.’’
382
varied points of view. Beyond this, specialized
courses are offered.
Technical laboratory courses in experimental
psychology furnish training in the fundamen-
tal principles of scientific procedure in observ-
ation, measurement, statistics, interpretation
and formulation of the laws of mental phe-
nomena. This course furnishes a technique
which should be employed in all branches of
psychology regarded as scientific or experi-
mental.
Physiological psychology usually reviews the
facts about the nervous system as taught in
neurology for the purpose of tracing the phys-
ical basis of mental life and showing the re-
lation between the mental and the neural.
Genetic psychology is divided into two parts;
mental evolution dealing with the training and
development of mental life in the species, and
mental development dealing with the unfold-
ing of mental life and the integration of be-
havior in the life of the individual. Within
this field lies also the problem of the inherit-
ance of mental traits.
Abnormal psychology deals, with mental
phenomena that are strange and irregular de-
viations from the normal but not strictly re-
garded as disease; such as hypnotism, medium-
ship, and alterations of personality.
Animal psychology presents a field of great
interest in itself; but it is of special signifi-
cance in that it throws light upon human life,
particularly in the study of the simplest and
the highest forms of animal behavior.
Social psychology treats of the social aspects
of mental life and often blends into other sub-
jects, such as anthropology, social origins, so-
cial ethics, social welfare, and eugenics. Some-
times race psychology, or the psychology of
peoples, is differentiated from social psychol-
ogy.
Individual psychology is perhaps the most
conspicuous field of interest at the present time
as it is the foundation for “human engineer-
ing” in all its forms of selection and guidance
of individuals as well as for an intimate and ac-
curate account of character or individuality of
a person. It has recently gained great impetus
through the development of so-called mental
tests.
SCIENCE
[Vou. LV, No. 1424
Statistical psychology is a basic requirement
for mental measurement, particularly as em-
ployed in mental and physical testing and in
psychology applied to education, commerce,
sociology, and vital statistics.
Psycho-analysis has come in from the medi-
cal side as a unique and new approach to, the
study of mental disorders such as hysteria,
morbid fear, aversions, and suppressed desires,
but also throws much light upon the nature ot
normal mental life. This is yet a polemic field
in which we find great enthusiasms and an-
tagonisms in contest.
Behaviorism is a purely objective study of
human and animal life without reference to the
testimony of consciousness.
These items may suffice to indicate roughly
the principal points of view that the student
entering upon a career in psychology must ac-
quaint himself with as each contributes a dis-
tinet element to the conception of psychology
as a whole.
APPLIED PSYCHOLOGY
Psychiatry, as the science and art of the
treatment of mental diseases, is the only fully
specialized profession which may be regarded
as applied psychology, although in many re-
spects it has developed independently and has
contributed much to normal psychology. But
aside from psychiatry proper, there are many
specialties in medicine in which expert know-
ledge of the human mind and behavior is fun-
damental; as in the care and treatment of
children, and the mental treatment of all types
of defectives and delinquents. Preventive
medicine, public health education, and sanita-
tion are built largely around psychology as the
science of human behavior.
Edueational psychology presents numerous
phases. Thus we have the psychology of the
course of study, of the child, of the adolescent,
of the learning process, of discipline, of par-
ticular types of training, and of special classes.
The science and art of education is primarily
applied psychology.
The psychology of business and industry
appears in several large and distinct fields;
such as the psychology of advertising, of sales-
manship, of personnel, and of vocational selee-
tion and various types of efficiency activities.
APRIL 14, 1922]
Legal psychology appears in two groups of
interest; first, the psychology of evidence or
testimony and pleading; and second, the psy-
chology of crime, delinquency, defective men-
tality, penology, dependency, correction, and
special types of mental deviation.
Applied social psychology takes such forms
as the psychology of social amelioration, eu-
genics, race betterment, child welfare, commun-
ity welfare, recreation and amusement, and vo-
cational and avocational guidance.
The psychology of art appears in the psy-
chology of music, of graphic and plastic arts,
and of literature, dealing in each case with the
psychology of art principles, the psychology
of the individual, and the psychology of train-
ing for the art.
The psychology of religion is applied mainly
in the interpretation of religion and religious
life, and in the organization of character build-
ing and religious education.
The above rubrics should not be regarded as
an adequate classification of the fields of pure
and applied psychology; they are listed merely
as a suggestion for the purpose of showing the
scope of the sciences and the types of outlets
for a career.
FITNESS FOR A CAREER IN PSYCHOLOGY
The requirements for a career in psychology
are in general the same as for other sciences;
and psychology presents a wide range of out-
lets through particular types of human interest.
In determining whether or not the student is
qualified for a career in science, he might make
use of a little device in applied psychology as
illustrated in the following rating scale:
ANALYZED RATING OF FITNESS FOR A SCIENTIFIC
CAREER
1. Reasoning power: capacity for solving prob-
lems, both deductive and inductive.
2. Originality: creative imagination, brilliancy,
planful initiative and fertility of rational ideas.
3. Memory: extensive, logical, serviceable, and
ready command of facts.
4, Alertness: quick, incisive, and responsive ob-
servation, thought and feeling.
5. Accuracy: precise, keen, regular and reliable
observation, thought and feeling.
6. Application: power of concentration, sus-
SCIENCE
high or low in all.
383
tained attention, persistence, and well-regulated
effort.
7. Cooperation: capacity for intellectual com-
panionship, team work and leadership.
8. Moral attitude: intellectual honesty, whole-
some moral standards, ideals and influences.
9. Health: nervous stability, physique, vitality,
and endurance.
10. Zeal for investigation: deep interest in and
craving for original and creative work.
Let the student rate himself and then ask three
or more persons whom he regards as most com-
petent and who know him well to rate him in-
dependently. Record the rating on a scale of
1-100 in which 1 represents the poorest exam-
ple of this trait, and 100 the best that the per-
son rating has ever observed in college students.
College students, as a selected class, then be-
come the “measuring scale.”
These grades may be grouped as follows:
1 to 10 very poor; 11 to 30 poor; 31 to 50 low
average; 51 to 70 high average; 71 to 90 ex-
cellent; and 91 to 100 superior.
These ratings will differ, but the very dif-
ferences may throw significant light on the
situation. For example, on “originality” the
professor of literature may rate an individual
low on the basis of observed work in poetry;
whereas the chemist may rate him high on the
basis of observed work in science. These rep-
resent two types of originality; or one person
rating may have encountered the flashy fertil-
ity of ideas, whereas another may have ob-
served a planful and persistent initiative,
both of which represent originality, but
of different types. For this reason the
ratings on a given trait should not be aver-
aged but analyzed. The student should seek a
full and frank discussion of the grounds for
each rating as this will analyze the situation
further and throw important light on the na-
ture of his character and capacities.
Nor should the ratings on the ten points ever
be averaged. A man may be very high in one
capacity and low in another and such differ-
ences are significant; but an average of them
would be misleading. No person is uniformly
These traits are not of
equal value; some traits are more essential for
one type of career than for another.
384
In general we may say that those persons
who rank above 50 in the most essential traits
give promise of achievement in a career in
psychology.
Natural interest is another factor of which
we should take account. A student seeking a
career in psychology may have the opportunity
of following his natural bent for interest in
pure science or its applications to the eduea-
tional, social, ethical, medical, artistic, and
other fields of human interest in which he may
find his natural bent.
TRAINING
The study of psychology is usually begun in
the second year in college; whereas many other
subjects are begun in the high school or in the
freshman year. As a result, it usually becomes
a more advanced subject and there is more
necessity for carrying it into graduate study.
Most standard colleges and universities now
offer good introductory courses in the subject,
but beyond the elementary work, the student
should seek institutions in which the particu-
lar phase of psychology that he desires to pur-
sue is most adequately represented. The best
is none too good for one who desires to special-
ize. In selecting, let the student choose, not
on the basis of size of institution, but with ref-
erence to the men who are recognized as most
worth while in a particular specialty.
As a prerequisite to a career in psychology, it
is desirable that one should have command of
French and German as a large portion of the
literature on the subject is in these languages.
He should also have pursued elementary
courses in mathematics, biology, and physics.
Other college subjects may be carried to ad-
vantage with, or in sequence to, an elementary
course in psychology.
There is now a movement on foot to provide
for the certification of psychologists. Such cer-
tification will be based on certain types of
courses, usually covering about three years of
graduate work, and will entitle the psychologist
to practice within his field of specialization.
Legislation covering such licensing is now be-
ing passed by dfferent states.
Psychology is a new science. In seeking ad-
vice, only those who are conversant with eur-
SCIENCE
[ Vou. LV, No. 1424
rent literature and present movements in the
subject should be consulted.
TYPES OF CAREER
There are at present four distinct types of
outlet :
Teachers of Psychology—The nature of this
work and its opportunities are perhaps best
known.
Scientific Research—The coming in of ex-
perimental psychology has epened up most fas-
cinating new fields of investigation and many
agencies furnish opportunity for a career as
original investigator. The leading universities
usually encourage this in connection with some
teaching; but there are opportunities in univer-
sities, scientific foundations, surveys, and pri-
vately supported enterprises for persons who
are unusually qualified for this type of work.
Specialists and Consulting Psychologists—
Here the opportunities are most varied and new
fields are opening rapidly as a result of re-
search in each of the branches of applied
psychology.
Technicians—All the specialists require tech-
nicians of various kinds as assistants. Most
of these positions are, however, used as step-
ping-stones or apprenticeships in the gaining
of experience for independent work.
Highly qualified advanced students can often
find scholarships, fellowships, assistantships,
and other financial provisions, given theoreti-
cally in recognition of some type of apprentice-
ship to graduate students. The remunerations
open to persons who seek a career in psychol-
ogy vary so much that figures would not be
significant. In general, they depend upon the
natural ability, the degree of training, and
successful specialization.

HORTICULTURE AS A SCIENCE!
Lixe most applied sciences, horticulture has
evolved by very slow degrees from an art, gov-
erned by rules justified by experience, to a
1 Read before the Association of Southern Agri-
tultural Workers, Atlanta, Georgia, February 21,

Aprit 14, 1922
science based on laws or principles of universal
applicability. The term “applied science”
would seem to connote that these laws or
principles are ascertained first and that they
are then applied to specific conditions, but as
a rule the applications are known and are
practiced, having been hit upon by empirical
means and the first function of an applied
science is usually to “explain” them by dis-
covering the principles involved. When a
considerable number of principles have be-
come established in this way, new applications
for them are found and the applied science
becomes in effect what its name implies.
A large part of the experimental work in
horticulture has been conducted with the object
of devising new rules and of ascertaining new
facts of an empirical nature. More recently,
however, considerable effort has been made to
find principles of more or less universal ap-
plicability and this has been accomplished by
a study of the fundamental factors determining
plant growth and productivity. Though many
valuable practices have not yet received
scientific elucidation and though much good
work remains to be done in the way of discov-
ering new rules, a large body of well estab-
lished principles has been accumulated and
successful practice depends to an ever increas-
ing degree on their recognition.
A comprehensive investigation of almost any
horticultural problem involves much the same
succession of stages as has been outlined for
the development of the science; (1) The field
for investigation is usually explored by ex-
perimental work of an empirical nature. (2)
This is followed by scientific study to determine
laws or principles. (3) This in turn is fol-
lowed by more experimentation to test the
feasibility of applying to particular conditions
the principles that have been discovered. It
seems customary to extol the scientific study
which aims to formulate laws and to dignify it
by some such appellation as “fundamental re-
search.” By implication, the attendant phases
of investigation seem to be deprecated on the
ground that they are largely empirical. How-
ever, this invidious distinction is unwarranted,
as every investigator learns sooner or later, for
SCIENCE
385
these three aspects of investigation are like
three links in a chain and progress in horti-
culture depends on their parallel development.
Principles are of little value to the horticultur-
ist if they cannot be applied, just as a collec-
tion of experimental data is of small import
until it receives interpretation.
The strictly scientific aspect of horticulture
is closely allied to botany and it is diffieult to
state wherein the distinction between the two
lies. It is largely a difference in emphasis,
since the horticulturist is interested only in
those phases of botany that may be applied to
his specific purposes. Nevertheless, the de-
velopment of horticulture has followed closely
in the steps of botany. During the last century
the attention of most botanists was directed to
morphology and taxonomy, a tendency reflected
in the advances made by horticulturists in the
subject of pollination and fruit setting and in
the development and description of varieties.
At present these subjects are better rounded
and more nearly complete in their major as-
pects than almost any other phase of horticul-
ture. Now that plant physiology is in ascen-
dency, more rapid progress is seen in the nu-
tritional problems of hortieulture—in fruit
bud differentiation, in pruning and in fertilizer
treatments.
The dependence of horticultural science not
only on botany but on other sciences as well
may be illustrated by reference to recent work
on the so-called Hardiness Problem. Although
this has engaged the attention of both horticul-
turists and botanists for many years, until
lately little was accomplished other than a sub-
stantial verification of the Laws of Tempera-
ture formulated by De Candolle nearly a cen-
tury ago. Investigators were still faced with
the seemingly contradictory facts that death
from low temperature is due to loss of water
from the cells by ice formation in the intercel-
lular spaces and that nevertheless hardy plants
usually contain less water than tender plants.
What seems to be a satisfactory solution of
this problem was made possible by some
chemical investigations of Foote and Saxton
at Yale University. This work showed that
water may exist in different forms, and that
386
the water held by colloids possesses properties
different from those of “free water,’ particu-
larly with regard to the temperature at which
it freezes. This work suggested to Bouyoucos
of the Michigan Agricultural College a classi-
fication of soil water into “free” water, which
freezes at 0° C. or slightly below, colloidally
adsorbed water which freezes at temperatures
from a few degrees below zero down to -78°C.,
and combined water, which freezes only at
temperatures below -78°C. This classification
was apphed by McCool and Millar to the water
of plant tissues. The work of these investigat-
ors suggested an explanation of the greater
tenderness of plant tissue with the higher water
content. If hardiness depended not on the
total water content, but on the content of col-
loidally adsorbed water which does not freeze
at ordinary freezing temperatures, then a plant
tissue might contain any amount of free water
and still be tender, while a relatively small
amount of water in the adsorbed condition
would impart a considerable degree of hardi-
ness. Recent investigations at the University
of Missouri have shown that these surmises
are correct, at least for some plants.
If hardiness depends on the amount of col-
loidally adsorbed water, what colloid holds it
in this adsorbed state? Some botanical in-
vestigations by Spoehr of the Carnegie Institute
suggested the probable answer to this question.
He found that in cacti water-retaining capacity
is correlated with pentosan content and that
when the water-retaining capacity is increased
or decreased by changes in environmental con-
ditions, the pentosan content likewise increases
or decreases at the same time. Pentosans were
therefore investigated in fruit plants and vege-
tables and a correlation was found between
pentosan content and hardiness. This corre-
lation is remarkably close if hot water soluble
pentosans only are considered. These findings
indicate that certain pentosans, probably pec-
tin-like substances, are the colloids that hold
water in an adsorbed state. This is further
substantiated by the fact recorded by Spoehr
that dryness tends to increase the pentosan
content ot cacti and likewise their water re-
taining capacity. It is well known that eul-
SCIENCE
[Vou. LV, No. 1424
tural practices or climatic conditions that tend
to dry fruit plants out in the fall, increase
maturity and hardiness. Consequently the very
conditions that lead to a low total moisture
content probably increase the amount of water-
holding colloids and the quantity of colloidally
adsorbed water—hence the greater hardiness of
plant tissues with the lower moisture content.
This understanding of the conditions asso-
ciated with hardiness in plant tissues permits
accurate outlining of the treatment or treat-
ments that decrease susceptibility to low tem-
peratures. It makes possible also an estimate
of the magnitude of the effects that may be
produced in that direction, and a recognition
of their limitations. Such practices thus be-
come incorporated in scientific horticulture.
This example indicates the intimate relation
between progress in horticulture and progress
in other sciences. Subjects which on super-
ficial consideration might never be suspected of
contributing data valuable for the solution of
horticultural problems are seen to be worthy of
study. If little headway has been made along
certain paths of investigation, it is not infre-
quently because the methods, the facts or the
technique essential to the solution of specific
problems has been lacking. To this day, the
official method for the determination of starch
recommended by the Association of Official
Agricultural Chemists is not an analysis for
starch but for total hydrolyzable polysaccha-
rides. Furthermore it is only within a com-
paratively few years that a_ satisfactory
method for determining total sulphur content
has been available. As a result, much pains-
taking labor has gone for naught, though some
have noted, but have been at a loss to account
for, the discrepancy between the results of
such determinations and the unmistakable evi-
dence of microchemical findings. The investi-
gator can well afford to acquaint himself with
recent advances in other fields and the broader
his fund of information the more successful he
will be. It might be suggested that progress
in Physics, Meteorology and Forestry should
be watched as well as that in various branches
of Botany, in Chemistry, Soil Science and
Agronomy. This task which would have been
Aprit 14, 1922]
out of the question a few years ago is greatly
facilitated now by the increasing number of
abstract journals and substantial help is af-
forded investigators in many institutions by
Plant Science Seminars, Scientific Societies
and the like. Even though such conveniences
be lacking much ean be gained by personal con-
tact with investigators in other fields and by a
mutual exchange of criticisms and suggestions.
Treatment — that is, orchard practice,
whether it be pruning, irrigation, fertilizing,
thinning or what not—is an aspect of horticul-
ture that may be compared to medicine, and
the comparison is instructive because it indi-
cates a possibility of development in horticul-
ture from the application of scientific methods
used by the physician or surgeon. Cultivation,
pruning, the use of fertilizers and other treat-
ments have been considered only in the light
of one standard, the effect on crop production.
The limitations of this one-tracked system may
be demonstrated by reference to some recent
experiments on fertilizer treatments.
Tf apple trees are bearing poor crops, a
spring application of some quickly available
nitrogenous fertilizer will frequently increase
the vield. Such inereases are very striking on
weak trees, but some results obtained at Mis-
souril show they can be obtained also on trees
in good condition—on trees that are already
bearing fair or even good crops. This effect
of quickly available nitrogenous fertilizers ap-
plied a couple of weeks before blossoming has
been shown to be produced by increasing the
set of fruit. Fruit setting, however, is only
one step in fruit formation. The process be-
gins with the formation of fruiting wood and
involves in succession fruit bud differentiation,
bud development to the time of blossoming,
pollination, fruit setting and finally fruit de-
velopment. The failure or limitation of a crop
may be occasioned by interference with any one
of these successive processes. It would make
little difference how favorable conditions might
be for fruit setting, if fruit bud differentiation
had not occurred. Recent investigations have
shown that those conditions in apple trees, pro-
duced by spring applications of quickly avail-
able nitrogenous fertilizers, which are so favor-
SCIENCE
387
able to fruit setting, do not favor fruit bud
differentiation. Hence if poor crops result
from deficiency in the initiation of fruit buds,
spring applications of quickly available nitro-
gen would only accentuate the trouble.
This work reopens for investigation the entire
orchard fertilizer problem which was thought
by many to have been solved in the last few
years by experimental work with sodium ni-
trate in the orchard. The same kind of fruit
tree may present many different nutritional
problems for treatment. Each problem re-
quires special study and the remedy in horti-
culture, as in medicine, depends on accurate
diagnosis. The use of fertilizers to correct the
alternate bearing habit in apple trees consti-
tutes a problem as distinct from their use in
increasing the set of fruit as spraying peaches
for San Jose seale is from spraying to control
scab. As investigators, we are too ready to dis-
pose of problems by assuming that either the
nutrition, the moisture or the temperature re-
lations are involved and that cultivation or the
application of some fertilizer will lead to
maximum growth and productivity. We would
spare ourselves the effort of analyzing the
problem—of making a diagnosis to determine
the precise difficulty to be overcome. The time
is not far distant when fertilizer treatments
alone will be as numerous and as specifie as all
the horticultural practices recognized today.
We must dispense with the idea of a mass at-
tack on a bulk problem and apply more de-
tailed methods, if we are to make rapid prog-
ress. Aside from technical improvements in
such fields as spraying and marketing, the lines
of pomological investigation along which great-
est progress seems possible are treatment, pro-
pagation and plant improvement and treatment
according to diagnosis promises to be one of
the most fruitful.
There is no cure-all, no patent remedy for
promoting growth, for inducing hardiness or
for inereasing crops. These can be accom-
plished only by careful study and hard work.
No practice can be recommended for all cir-
cumstances or for all fruit plants, nor can the
same practice be guaranteed to produce the
same effects under different conditions. Treat-
388
ment should be regarded not so much in terms
of practice as in relation to the specific phys-
iological processes to be affected. Much work
must be done before specific measures to in-
fiuence these different processes in the desired
direction are found. Many practices that have
not proved generally efficacious in the past may
be shown to have great value for specific con-
ditions. Pomologists must think in terms of
limiting factors, and not merely in terms of the
soil elements that may limit plant growth but
also in terms of the physiological processes
that may be limiting fruit production. For all
this work, an accurate knowledge of the chemi-
cal changes associated with different physiolo-
gical processes is of the utmost value because
a thorough understanding of the conditions de-
sired may suggest means for their accomplish-
ment.

A SUGGESTION AS TO METHOD OF
PUBLICATION OF SCIENTIFIC
PAPERS
THE processes of scientific publication are
admittedly in an unhealthy state. Various in-
fluences contribute to the acuteness of this
condition, but it is likely that a time of stress
has merely emphasized weaknesses inherent in
the ordinary procedure for printing scientific
papers. The “jammed” plight of the periodi-
cals is slowing the vital current of new results.
It becomes desirable to consider alternative
methods of printing, perhaps better adapted
to the present character of our needs. In this
country and abroad several suggestions have
already been offered; the most drastie of these
has urged the publication of abstracts only,
‘completed manuscripts to be deposited for
reference in some central place—a scheme hay-
ing so many unfavorable features as to merit
little serious attention; it is not merely results
we wish, but also some at least of the steps
in their derivation.
I have in mind more especially the field of
zoology. To-day this subject is specifically
served by a fine group of journals, and by an
SCIENCE
[Vou. LV, No. 1424
“advance” bibliographic service of filing cards
bearing author-abstracts. This system of pub-
lication is maintained through the cooperation
of the Wistar Institute. These journals were
founded some years ago, and each was de-
signed to cover a particular group of zoologi-
eal interests. They do not now correspond, in
titles or in any individuality of contents, to
major aspects of zoological development.
Their fields of service overlap, sometimes to
an embarrassing degree.
Investigators acquire separata of papers of
particular coneern to them. There is thus
brought about a quite unnecessary duplication
in the distribution of published work, and a
proportionate waste of paper. Subscriptions
for support of the journals are drawn from
membership dues of the Zoological and Ana-
tomical societies. Members therefore receive
most or all of the journals, in this way accu-
mulating a mass of unused, largely unusable,
material; while still necessarily relying upon
the convenient “reprint” for actual reference
and use.
I believe that these difficulties may be ob-
viated, and the course of publication simplified
and expedited. With the hope of attracting
discussion of this matter, I outline here a plan
regarded as practicable and to the point. The
foundation of new journals has little to recom-
mend it; these are likely soon to suffer the
fate of the older ones. Save in some special
fields, the journal method of publication has
become measurably antiquated.
The journals should be abolished. They do
not represent rational subdivisions of zoologi-
cal activity. There is no real reason why pa-
pers accepted for publeation should be
grouped to make up a “number.” It is cer-
tainly more desirable that a paper be printed
when it is ready for printing. If issued and
originally distributed as a “separate,” unneces-
sary duplication of distribution ean readily be
avoided. This plan requires some central
agency, such as we now have, for handling the
mechanical details of publication. Serial
numbers could be assigned to papers as issued.
An entire series might then be bound by li-
braries, though the more sensible way would
APRIL 14, 1922
be to have them filed alphabetically by authors.
In some essentials this procedure is already
followed by the Archives de zoologie expéri-
mental et général, by the Royal Society in its
Transactions, by the Museum of Comparative
Zoology, and by the University of California
Publications. My suggestion, however, in-
volves an important additional element. So-
ciety subscriptions continuing as at present,
it would be a simple matter to have each mem-
ber receive a certain number of published pa-
pers, more or less equivalent in total bulk
to the journals now obtained. But it would be
possible for the subseriber to select, through
the Advance Abstract Bibliographic Cards,
those papers specifieally desired. Additional
papers, not regularly obtained in this way or
from the authors, could then be purchased at
small extra outlay. The American Anatomicad
Memoirs and the few special reprints issued
by the Wistar Institute have made a_ begin-
‘ning in this direction.
The actual working of this plan would per-
haps require that at, say quarterly, intervals
there be issued Bibhographie Cards carrying
the serial numbers assigned to the individual
papers about to be printed. An accompany-
ing order blank, by which articles desired could
be requested by number, would give a simple,
quick method of indicating one’s needs. It
would at the same time serve to show the
printer the size of the issue to be prepared,
after allowance had been made for
stock and for blanket subscriptions. The three-
months’ period mentioned is sufficiently long.
The experience of the Journal of General
Physiology shows that with efficient manage-
ment if is possible to print accepted articles
within less than that time, even under present
conditions.
reserve
Authors should by this scheme be in some
degree relieved from the expense of purchas-
ing separata for extensive private distribution.
One’s library shelves, moreover, would no long-
er be encumbered with journal numbers which
must be bound at ruinous expense or else re-
main unsightly.
Any working plan of this type must be con-
ceived as applying chiefly to contributions of

the character and average length now appear-
ing in the journals. Incidentally, this scheme
may show the way out of the difficulties some-
times made in connection with the rather ar-
bitrary rule now enforced by the journals as
to the maximal length of acceptable contribu-
tions. Although sometimes abrogated for
reasons obscure, it has tended to be avoided by
authors sphtting the material of an essentially
unitary piece of work into a number of ar-
ticles. While the length rule has perhaps act-
ed to restrain some wordiness, it is hardly a
rational rule; one could wish it supplanted by
editorial persuasion !
It may be suspected, as a conceivable result
of the plan outlined, that the quality of the
papers might be automatically improved. 5 ie wein® Richards | Henglein?

line, and the molecular volumes of numerous
halogen-substituted compounds; for salts, the
molecular volumes of practically all metal
halides, the volume change in solution, the
melting points, boiling points, latent heat of
vaporization, heat of formation and_ specific
compressibilities of the alkali halides and many
others, the percentage contraction for halides
of small cations, the distance between the cen-
ters of oppositely charged ions in crystals, and
the radii of ionic halogens.
There are many interesting
item in the above enumeration of which space
does not admit detailed consideration. For
example the percentage contraction undergone
when a salt is formed from the free elements,
is found in this work to be related in a funda-
mental way to the properties of the complex
compound formed from it. Thus when a
nickel halide is formed by the union of nickel
with any of the halogens (fluorine, chlorine,
bromine, or iodine) the percentage contraction
is the same (22.5 per cent.) in each of the four
cases. In the case of the cobalt and cupric
halides the magnitude of the contraction is not
quite constant, but increases slightly from the
fluoride to the iodide. The constaney of the
percentage contraction is also found when any
halogen is combined in turn with the alkali
metals (lithium, sodium, potassium, and ru-
bidium). The contraction amounts to 60 per
cent. each for the four fluorides, 43 per cent.
each for the four chlorides, 38 per cent. each
for the four bromides, and 30 per cent. for
the four iodides. It is seen that the relative
contraction decreases with increasing number
of non-nuclear electrons in the halogen atom.
The contraction for the cesium halides is
greater than that given above for the other
alkali halides. However in the oxy-acid salts
cesium shows the same contraction as the other
salts of the alkalis, and in molten halides it is
details of each
also perfectly normal as indicated by the eare-
ful researches of Jaeger. The anomaly of
cesium is therefore to be attributed to differ-
ence in crystal form. As a matter of fact
cesium halides possess cube-centered lattices,
while all other alkali halides are simple cubic.
The ionic radii can be derived from experi-
mentally determined crystal distances only by
means of some assumption. The following
table shows the widely varying values, multi-
plied by 108, which have been presented by
eight workers.
It is a singular fact that in spite of the wide
discrepancies all of the values except those of
Richards are quite accurately linearly related
to the atomic volumes of the halogens at the
boiling point, showing that whatever basis of
calculation may be the closely similar halogens
are still related to each other in relatively the
same way. Richards’ values are calculated
from the atomic volumes of chlorine, bromine
and iodine at 25° where the three values are
practically coincident, and this may explain
the deviations in this case. However the third
powers of the radii values, as direct functions
of the volumes of single combined atoms, are
found to be linearly related to gram-atomic vol-
umes. This is apparently of greater signifi-

of Henglein, whose procedure is very ques-
tionable inasmuch as he takes Fajans’ values
for bromide and iodide ions and _ then
assigns values to chloride and fluoride so
that a straight line connects the molecular
volumes of the halides of any alkali metal and
the sizes of the substituent halogen ion. By
using the same process for determining the
sizes of the alkali ions it is of course possible
at once to write an equation by which the
molecular volumes may be ealeulated from the
constant size of the ion. Henglein quite nat-
urally observes a very good agreement between
calculated and experimental values.
Table I indicates the definite progression in
size and properties from one member to the
next in such’ nearly perfectS families (or
groups) of elements as the halogens and the
alkalies.
It is interesting in this connection to com-
pare the radius of the ammonium ion. Using
the distance between ion centers found by
Bartlett and Langmuir for the ammonium
halides, and subtracting the radii of the halo-
gen ions, the ammonium ion is found to have
a radius of 1.99 not only in conveying a great
deal of information, but, what is more
important, the probable significance of
our knowledge with a due appreciation
of its limitations. .... i

INDIVIDUALISM IN MEDICAL
EDUCATION!
In human progress there are two funda-
mental processes which sometimes proceed
equally, but usually one or the other is dom-
inant,—these two processes are extension and
consolidation. In the birth and growth of na-
tions, there is first settlement in colonies due
to community of thought and action; this ex-
pansion is followed by a union; national ex-
pansion leads to international alliances; the
expansion of alliances leads to consolidation
into world leagues. In the growth of religions
many beliefs are unified by the Christian reh-
gion; then extension of doctrines leads to
innumerable sects, followed by attempts at
consolidation. In. the more specialized fields
of activity the same processes are observed. In
celestial physies the theory of gravitation co-
ordinated the scattered and divergent views;
then a period of differentiation, followed by
attempts at coordination in the theory of rela-
tivity. In the field of medical science there
are many illustrations of the same procedure.
Seattered observations on variations in the
blood, phlegm, and bile, during illness were
brought together in the humoral theory of dis-
ease; in like manner studies on bacteria were
unified in the germ theory. Studies on heredity
and environment found common expression in
the theory of evolution. In the past, medicine
was largely restricted to the diseases of man-
kind. At present she recognizes the intimate
relationships of the diseases of plants and ani-
mals to those of mankind. In the near future
she must take into consideration the diseases
of metals; ultimately her domain will extend
widely over both the organie and inorganic
world. In the growth of knowledge in all of

its special fields and great provinces, and as a
whole, two processes stand forth, namely, ex-
tension and consolidation, specialization and
generalization. The vitalizing factors in these
are: individual thought, and collective thought.
Whether one follows the theory of evolution
or accepts the teaching of the book of Genesis,
he must contemplate the beginnings of intellec-
tual growth in the individual. Individual
thought precedes collective thought. Individu-
alism, in the abstract, postulates that each
human being may live to the fullest extent his
own life as he wills. According to Biblical
history it attained its greatest development
with the first inhabitant of the earth but did
not reach its ideal. The family embodies the
first step in the growth of collective thought;
and as the family grows individuality becomes
restricted. Here and there it breaks away
from the common modes of thought and action
and asserts itself in differences so pronounced
that one member becomes a genius while an-
other becomes a black sheep—a Rocail and a
Cain. Roeail erects a sepulchre adorned with
statues of various metals, made by talismanic
art, which move and speak and act like living
men. Cain becomes jealous and envious of
Abel and murders him.
Community life further accentuates common
thought and is necessary for the preservation
of mankind; but with its growth, individuality
is again repressed. Through the ever inereas-
ing restrictions brought about by unity of pur-
pose and organization, individuality is forced
toward the average. Ideas either destructive
or constructive must go up or down to the
level of common thought. Great leaders,—
philosophers, statesmen, and _ scientists,—have
been those who have resisted these equalizing
forces. Now and then a voice cries out: “Here
am I Jone wanderer in endless search of myself.
For xons I have been searching from star to
star down the ages until I chanced this way. . .
I love the idea of equality, fraternity, democ-
racy, but I must soon leave this crowd and
wander on until I come to the kingdom of my
solitary soul.” He who explores ways of
thought or action far ahead of his contempo-
raries must have an inner world in which he
passes long and solitary hours. If he be en-

[ Vou. LV, No. 1426
gaged in scientific experimentation, in an un-
known land with neither map nor sign post,
he may lose his sight as did Bunsen, or his
life as did Lazear.
If the development of individuality be ig-
nored one of the greatest forces in the progress
of mankind is lost to the world. On the other
hand, the principle of collectivism underlies
our entire social organization. It develops a
general bond of likeness between the one and
the many; it makes the individual a part of
the whole; it leads to similarity, equality, fra-
ternity, democracy. It enables us to move in
companies, regiments, battalions, divisions,
and armies. Without it, a nation sinks into
oblivion and a world may be lost. Without
individualism the same is true. A commander-
in-chief, a great field marshal, is as necessary
as the army. A million souls submerge their
individuality for a common purpose, but each
cries out, Where am I going? What am I
doing? What I have in myself is moribund.
I am physically an automaton, and intellec-
tually boots, boots, boots.
The child accepts life as it is; it sails in a
ship over seas that are calm; it knows naught
of the larder, ballast or sails; the length of
the voyage; the course or the destiny. Its life
is in another’s keeping; its own life is un-
known; nothing stirs from within. The youth
thinks of the ship; the voyage; the strange
lands which bid him come. Self is beginning
to assert itself; something stirs from within.
Maturity builds a ship, earefully equips it,
and sets forth on an uncharted ocean in quest
of a new world. Something within takes pos-
session of the heart and soul and guides every
act.
Edueation is the bringing out of something
from within; not the foreing of something in
from without. Its emblem was written by an
unknown hand on the walls of Delphi—
“KKnow thyself.” It is this something within;
the personality, the essential self, the indi-
vidual which must receive greater considera-
tion in our schools. What I have in common
with others is best developed by the school.
What is mine and mine alone can not go to
school with any one but it can be stimulated,
intoxicated, liberated.

Let us proceed with the central thought;
greater men in medicine through greater liberty
in medical education. A medical school is
built upon the same general foundation as any
other institution. Purpose, products, materials,
and methods form the corner stones.
The purpose of the medical school is to train
men in the application of scientific methods
to the prevention, alleviation, and cure of dis-
ease, and to advance medical knowledge in its
broadest sense.
The products of medical schools may be con-
sidered as belonging to three principal groups:
the practitioners, the investigators, and the
teachers. A survey of the medical profession
at large shows that its eminent men usually
may be placed in one or the other of these
groups; sometimes in two, but rarely in three.
The group of practitioners comprises those
whose primary interests are in the alleviation
and cure of disease. The group of investiga-
tors includes those whose deepest interests are
in the causation and prevention of disease. The
group of teachers contains those whose princi-
pal aims are the dissemination of the methods
adopted and the results achieved by the practi-
tioners and the investigators. Lister, Pasteur,
and Osler typify the groups.
A few decades ago, the country demanded
and the schools furnished, for the most part,
but one type of practitioner, and that type was
the all-round practitioner. He was obliged to
know something of medicine, surgery, and ob-
stetries, together with dentistry and pharmacy.
In addition to these, he was expected to show
proficiency as a veterinarian. The conditions
of to-day are so different, that the all-round
practitioner of to-day would have been a spe-
cialist fifty years ago. The cries from the
country for general practitioners are heard far
and wide but are less and less heeded by the
young graduate. A doetor who has had mod-
ern training in laboratories and clinies with
apparatus and libraries and contact with pro-
gressive men, is quite unwilling to leave all
these. Moreover he can not come up to dear
old Dr. Brown to whom physiognomy revealed
more than modern laboratory methods; who
did many a successful major operation on the
kitehen table, and who thought nursing and a
SCIENCE
439
controlled environment entirely superfluous.
The ambitious young doctor of yesterday, fol-
lowing the advice and example of his success-
ful seniors, went forth to do an all-round prac-
tice for a number of years before entering
upon the study of a specialty. Away from
libraries, laboratories, clinies and stimulating
colleagues, he found little growth or expan-
sion, beyond that indicated by adipose tissue.
The ambitious young doctor of to-day who
contemplates a career as a specialist dispenses
with this hibernating period of two or three
years and seeks instead the live atmosphere of
the hospital, an assistantship to the master, or
a fellowship in some one of our great founda-
tions. The rural districts and small towns will
be obliged to adopt something of the same
methods that they long ago adopted in secur-
ing churches, schools, and factories—they will
be ebliged to build and equip hospitals if they
hope to obtain modern medical service. With
the hospital comes the staff which, in turn,
forms the basis of the group clinic. Instead
of the general practitioner making a complete
diagnosis, there is a group of collaborating
clinicians, each of whom is an expert in his
particular field. The rapid development of the
group clinie is creating a situation which must
be recognized both by the profession and the
schools.
. The practitioner of the future, either gen-
eral or special, not only must measure up in
self-reliance, responsibility, and judgment to
the practitioner of the past, but also must be
better trained and more thoroughly imbued
with the investigative spirit.
Each patient presents a problem, the solu-
tion of which is more difficult than that in
almost any other field of science. While every
medical problem must be approached through
the avenues of physics, chemistry, or biology,
the physician is often baffled at the very be-
ginning of his work by the fact that he is
unable to determine which will aid him most.
Often he finds that no one of these sciences
will solve the problem but that all are involved.
Physies may explain the mechanism of joints
and muscles; it may aid us in the interpreta-
tion of the effects of light, heat, electricity,
osmosis, pressure, on living tissues, but it does
440
not explain, nerve impulses, sensations, mem-
ory, or thought. Chemistry may teach us the
rates of protein, carbohydrate, and fat meta-
bolism in health and disease; it may help us to
know more of the precious vitamines and hor-
mones but it does not tell us why one child
resembles the father or mother physically and
mentally, while another child does not. Biology
may aid us in solving this problem but she, too,
is extremely jealous of her secrets. She read-
ily acknowledges that the process of fertiliza-
tion is essentially the same throughout the
animal kingdom, but she teaches us that the
processes of regeneration are entirely different
in different forms, and cautions us not to infer
that a new leg will grow out from the stump
of an old one in man as it does in some of
the lower animals. She teaches that the organs
of seeing, of hearing, of smelling, of tasting,
of feeling, are the organs through which these
sensations habitually are received. But she
warns us not to infer that the loss of one of
these special sense organs means an entire loss
of that special sense. Our senses overlap to
a degree which we little realize; light percep-
tion through the skin; sound perception
through all parts of the body; color perception
through both sound and smell; are a few of
the many possibilities as revealed in the lives
of Laura Bridgeman, Helen Kellar, Willetta
Huggins and others. Deductions from the phe-
nomena presented in these various fields are
extremely hazardous and emphasize the neces-
sity of working through the avenues of multiple
hypotheses in the interpretation of disease.
When this has heen said, let us also recall that
the names of diseases, of their courses, and of
their processes are broad, generic terms, which
signify physical, chemical, and biological com-
plexes. Acuteness in observation; precision
in experimentation and caution and judgment
in deduction are the essentials for the inter-
pretation of disease. They are the A.B.C. of
the practitioner of the future.
One of the greatest needs in our medical
schools of to-day is the encouragement of stu-
dents to devote their lives to the study of the
causation and prevention of disease. It be-
comes more and more apparent, as set forth
last year by the committee on graduate work,
SCIENCE
[Vou. LV, No. 1426
that the medical schools must give opportunity
and encouragement for men to develop as re-
search workers. We need no longer argue that
reproductive scholarship must be supplemented -
by productive scholarship. We accept the
established fact that the investigative spirit
must pervade the atmosphere of the medical
school. Frequently a student stands where the
roads fork and, as William James puts it,
“one branch leads to material comfort, the
flesh pots, but it seems a kind of selling of
one’s soul; the other to mental dignity and
independence, combined, however, with physical
penury. On one side is business, on the other
science.” It is not enough for the student to
stand in deep perplexity outside the private
door of his teacher and whisper that research
work is going on inside. He must be invited
in, and given time to accept the invitation. It
is therefore necessary that some provision be
made whereby any student may come more
intimately in contact with research methods
and ideals than is possible in our medical
course of to-day. How far we ean organize
research is a question. There is no doubt but
what to some extent we can create the inves-
tigative spirit. At any rate, we can help the
young man who evinees this spirit; we can give
him time; furnish him with apparatus and
books; point the way to fields of investigation;
discuss his problems and help him in kis ex-
periments. We can not dominate him nor
restrain him. We can not force him to work
independently or in cooperation; this must de-
pend upon his bent, his personality, his indi-
viduality,—genius can not be organized nor
ean it go to school.
In every medical school there are those who
are deeply interested in presenting summaries
of the progress made in certain fields of medi-
cine, or in the entire province of medicine.
Their object is to sift out and correlate well
established procedures. They may be neither
practitioners nor investigators in the sense pre-
viously mentioned. They are so to speak the
editors of medical facts and theories; the com-
pilers; the writers of textbooks; the historians.
This group we may designate as teachers or
medical journalists. I am fully aware that this
group is one created by American institutions
AprRIL 28, 1922]
and will doubtless become extinct in time for the
simple reason that teaching must be accompa-
nied by thinking; teaching and research are
inseparable. The great teacher has always pos-
- sessed the investigative spirit but may not have
been a great investigator. We must, at present
make provision for those who wish to prepare
for teaching in its broadest sense.
These three types have been designated as
they exist to-day. They are generic rather
than specific. They possess many attributes in
common and may sometimes form a trinity.
The materials to be converted by one method
or another into the products set forth are stu-
dents who enter the medical school with a high
school and at least two years of college train-
ing. There are no two who have followed the
same course of study with the same degree of
interest or who have reached the same results.
In the high school the student feels his way
through a large range of group electives, and
often before entering college he has decided
that he will major in agriculture, engineering,
law, theology, or medicine. In his college
work, electives have enabled him to accentuate
his choice or perchance to find that his deci-
sion was wrong. In both high school and col-
lege the student may have inclined toward sub-
jects involving manual training and thereby
have acquired keenness of touch and dexterity,
or toward music, cultivating the sense of hear-
ing. He may have elected biologic sciences,
accentuating observation. He may have turned
toward mathematics, physics and chemistry,
emphasizing precision in deduction and ex-
perimentation. He may have laid special
stress on history or languages thus acquiring
an excellent memory and facility of expres-
sion; or perchance on philosophy thus devel-
oping the power of abstract thought. Those
of us who come in contact with these men as
they enter upon the study of medicine are
impressed by their differences in concept, habit
and training. He who comes from the land of
mighty oceans, forests, and mountains, thinks
in larger terms than he who comes from the
truek farm. The boy brought up in the coun-
try better understands the thought and action
of the country folk than the boy brought up in
the city. The boy who is reared in the highly
SCIENCE
441
commercialized districts of a great city regards
an education in quite a different light from the
one who is reared in a college or university
town. One student is always on time, another
is always behind time; one works quickly, an-
other slowly; one is deft, another clumsy; one
student retains best what he sees—his memory
is visual; another retains best what he hears—
his memory is auditory; still another remem-
bers best what he reads—his memory depends
on word association. One mind stores up
isolated impressions and facts—it is analytic;
another arranges impressions and facts in
groups—it is synthetic. Will the student who
is slow and clumsy ever make as efficient a
surgeon as the one who is quick and deft? Will
the one whose memory is auditory, or depends
on word association, ever succeed in surgery
as well as another who is able to visualize the
positions and relations of organs in the body?
Will the student who has an untrained ear
ever make as efficient an internist as the one
whose keenness in sound perception and dis-
crimination enables him to differentiate be-
tween normal and abnormal sounds in the lung
or heart? Is the one which an analytic mind
as capable of interpreting a syndrome as an-
other whose mind is synthetic? It is beyond
question that the men who enter the medical
school at the age of 22 or 23 years are quite
unlike in their mental equipment and this fact
must be taken into account in the medical cur-
rieulum.
The method of the medical school is the eur-
riculum; around it centers, to a large extent,
the resources of the school, and through it are
expressed the principles and concept of medical
education. The curriculum of half a century
ago was probably the best that could be devised
to meet the needs of the profession and schools
of that day. From an economic point of view,
it was highly advantageous; one teacher could
lecture to a large number of students and was
entirely relieved of the time consuming instruc-
tion to small groups and individuals. It was
an excellent mechanism for turning out one
type of general practitioner. While it served
in part as an intellectual pathway, it also
functioned as a “straight jacket.” It kept the
students so busy that they could not destroy
442
much property nor throw out many professors.
To-day the conditions are entirely different.
The financial situation has changed so that the
school is no longer a recipient but a donor.
The students are better trained both in be-
havior and intellect and are more eager for
instruction. Many teachers are on a voca-
tional basis and are able to give more time to
instruction. Moreover, the medical school no
longer looks to a single product, but to many
products. The fixed curriculum of half a cen-
tury ago will not meet the conditions of to-day,
yet, in principle, it has remained unchanged.
Our national organizations dealing with med-
ical education have recognized and emphasized
the need of a more liberal curriculum but have
not adopted measures that materially assist the
medical school in the development of such a
curriculum. The fixed curriculum is so deeply
rooted, so widely spread and so thoroughly
fostered by standardizing bodies and educa-
tional institutions that state examining boards
are rapidly adopting or creating such curricu-
lums as the basis for medical licensure. “Hight
months in each of four separate calendar
years,” devised for the improvement of medical
education became a serious obstacle to patri-
otie service during the late war, and is no less
an obstacle to education at the present time.
A curriculum covering 4,000 prescribed hours
is another mechanism to protect and advance
medical education but it has defeated thinking.
Medicine and medical specialties, 900 hours;
surgery and surgical specialties, 648 hours;
obstetrics and gynecology, 216 hours; are arti-
ficial divisions proposed by the medical edu-
cational bodies as a means of insuring better
trained physicians and of eliminating bad
medical schools, but these regulations have re-
sulted in the state boards going one step fur-
ther with the same good intent. But what a
handicap has followed as a result of these
measures. One state requires 170 hours of
general pathology, another 240, another 250,
and still another 270. Like variability is
found in practically all the subjects in the
state board curriculums. Certain peculiar re-
quirements are exacted by some of the state
boards. For example, one says in substance,
either teach 60 hours of electro-therapeuties or
your graduates can not practice in our state.
SCIENCE
[ Vou. LV, No. 1426
The day is not far distant when the schools
must either incorporate in their curriculums
the particular requirements of each state board
curriculum or find that their graduates are not
qualified to practice in these states. To incor-
porate these requirements means an enormous
time expansion and this is impossible. The
schools are thus approaching an impasse of
their own creation and some remedy must be
found. The one obvious solution is the erea-
tion of an elastic curriculum. The students in
entering the medical school with a fixed eurricu-
lum are beginning a four-year program that
requires all to do essentially the same kind
and the same amount of work at the same time
and in the same way. ‘They are leashed to-
gether, made uniform in action and thought
like the rowers in a great galley; shackled
hand and foot, heart and soul, with chains of
our own forging. It follows that the more uni-
form the special senses and _ intellectual
processes, the more efficient becomes such a
curriculum. To reach its maximal efficiency,
we must revamp and equalize the special
senses and intellectual processes,—but is this
education?
The fixed and congested curriculum of to-
day must give way to an elastie curriculum
which is adjustable not only to these perplexi-
ties but also to instructional resources, clinical
resources, and to the growth of medical sci-
ence. It must provide for collective teaching;
cooperative study and individual study.
Alexander Bain tells us that in the Scottish
universities prior to the eighteenth century the
quadrennial arts course was conducted by so-
called regents, each of whom earried the same
student through all the four years. In a
rectorial address to the students of Aberdeen
University, in 1882, he said: “You the students
of arts, at the present day who encounter in
your four years, seven faces, seven voices,
seven repositories of knowledge, need an effort
to understand how your predecessors could be
cheerful and happy confined all through to
one personality; sometimes juvenile, some-
times senile, often feeble at his best.” Con-
trast this with the condition to-day, when sey-
enty faces, seventy voices, and seventy person-
alities are encountered by the medical students
in the four years of their course. To the
ApriL 28, 1922]
single instructor the student could carry his
entire intellectual possessions; to each of the
seven, one seventh; to each of the seventy, he
can carry but one seventieth. But what
instructor realizes this and is willing to accept
his proportion? Each demands more than the
student can give, and the student under this
tremendous pressure loosens his hold on the
get-something idea, adopts the get-by methods,
and revises his ethical principles accordingly.
Probably no field of science is undergoing a
more active fermentation than medical science,
with the splitting off of new segments; the dis-
carding of certain subjects; and the addition
of new subjects. Just as physiology and path-
ology split off from anatomy, so biochemistry
is outgrowing physiology; bacteriology is
asserting its independence of pathology; pedi-
atrics and neurology, otolaryngology and oph-
thalmology are attaining independence from
general medicine and surgery. Owing to the
increase in entrance requirements, certain sub-
jects like chemistry, embryology, histology and
comparative anatomy are being shifted from
the medical course to the premedical course,
while other subjects like osteology, bone mod-
eling, etc., have fallen by the wayside. Again,
there is going on a continual importation of
subjects from the outlying fields of investiga-
tion. Immunology, Roentgenology and para-
sitology have been brought into the curriculum
from these outlying fields. The schools that are
most actively engaged in the exploration and
investigation of borderland subjects find great-
est difficulty in holding to a fixed curriculum.
The clinical resources of one school may be
quite unlike those of another. One is favorably
situated for the study of tropical diseases, an-
other is able to utilize a great tuberculosis sana-
torium, another a great psychopathic institute.
The school should be,able to adjust its curri-
culum to these resources. If in South Africa,
study sleeping sickness in the clinic, in the
class room, and in the laboratory. If in
Panama or Louisiana, emphasize, if you wish,
malaria; if where cretanism abounds, study it,
teach it and think it. While one school may
thus emphasize this or that particular line of
study, all are studying disease, and the under-
lying principles of disease prevention and con-
SCIENCE 443
trol are not distributed geographically. Upon
the proper certification that a student has had
four or five years training in a good medical
school should rest his qualification to practice.
If it be expedient to protect the public by
some form of state or national examination
such examination should be directed solely
toward determining the student’s ability to
work and think in terms of disease prevention
and control.
The principle of collective teaching in all
education is based upon the assumption that
all human beings possess certain resemblances
both physical and mental; otherwise we could
not speak of them as a group. Hach person
possesses more or less of every ordinary
human power. Our senses of feeling, tasting,
smelling, hearing and seeing are similar; their
actions and interactions upon an inherited
substratum are reflected in thinking, and modes
of thought run along fairly parallel lines. Col-
lectivism stimulates a spirit of emulation; of
comparative evaluation of mental assets both
quantitative and qualitative. It arouses a
sense of power which enables a member of a
group to overcome obstacles which would de-
feat him if he were alone. This is forcibly
illustrated by the heroic deeds of the soldier
when inspired by the common purpose of the
group. The status of the medical profession
demands many elements of collectivism. There
must be developed in the medical students a
fraternal sympathy; a spirit of mutual consid-
eration, and a basis for disciplined, or expert,
cooperation. There is a fairly common sub-
stratum in each subject, in each great division,
and in the curriculum as a whole, which can
be presented collectively, and whether or not
this be the method of the future, it must be
the method of the present because it is an
economic necessity. These are some of the
considerations which justify class lectures,
class demonstrations, class experiments and
class examinations. It must not be inferred,
however, that it likewise justifies the existence
of the present division of students into fresh-
man, sophomore, junior and senior classes.
This grouping is a menace to education and
should disappear as soon as possible, especially
in the medical school.
444
The spirit of cooperation between faculty
and students in medical training is one of
greatest value to the student, not only for the
school period, but throughout his entire life.
In order to develop this spirit, we should de-
termine as far as possible the special assets of
each student at the time he enters the medical
school, and ever keep in mind his adaptability
for certain kinds of work. Much can be
learned through contact afforded by laboratory
work and through the seminar. This should
be supplemented by a knowledge of his home
life, his living conditions and his social habits.
Through careful observation and inquiry, we
must obtain as clear a picture of the student’:
individuality as is possible. With this as a
guide we should help him to place his assets
where they will yield the greatest returns. HEx-
perience teaches that most students, at the end
of the second or third year of the medical
course, have decided whether they wish to lay
equal emphasis on medicine, surgery and ob-
stetries, fitting themselves for general practice,
or to give some emphasis to one, fitting them-
selves for a special field. If, in the judgment
of the faculty, the student’s selection is wise,
he should be permitted to accentuate his choice.
In the fourth year the student should be
allowed a further latitude which will permit
him again to accentuate the all-round training
in medicine, surgery and obstetrics, or to lay
further emphasis on one of these. In the fifth
year, he should be given the liberty to round
himself out for general practice as an interne,
or to add to his special training, or to do inde-
pendent work in research. Collective teaching
and cooperative study are both necessary but
they both are drawn into a common vortex
unless supplemented and invigorated by indi-
vidual study.
Individual study alone starts the waves
which roll on and on toward the unseen and
unknown shore. Working in harness is most
excellent for the development of the team, but
the freedom of the fields is necessary for the
growth of the individual. What an inspiration
comes through the exploration of the limitless
fields! What a thrill comes when the indi-
vidual receives a new interpretation or new
revelation of nature’s laws! How hopeless to

[Vou. LV, No. 1426
read a description of the country one is about
to explore. It is known only by exploring it.
Individuality derives strength from the history
of science, its workers and their work; but no
record or experience coincides with it. They
are as guide posts which disappear at the fron-
tiers of science and individuality must wander
on alone. The light from the north star may
direct its footsteps but the light which comes
from the soul spurs it on. The traditional
home of individuality is in the university, and .
here is the one place where it should be fostered
and encouraged. It is fair to presume that in
each of our medical schools there are to-day
students of great potentiality who need but
the stimulus and opportunity to become leaders
in science. How shall they be given the oppor-
tunity. One of the simplest of the initial
steps to be taken would be to grant them the
privilege of electing a certain portion of their
work both quantitatively and qualitatively. The
privilege of adjusting study to capacity should
be restored. It was distinctive of the earlier
ages and each successive generation has lessened
the privilege. The students of our day are ex-
pected to know more and must consequently
attempt to learn more than the most brilliant
intellectual leaders of the past, who would be
content to-day with the schooling of Horace,
of Shakespeare or Darwin. Where they
learned one thing we are attempting to learn
a half dozen. They acquired knowledge; we
attempt to. We ean not keep the medical
students marching in the trodden paths of their
predecessors until weary and heartsick they
complete the march, only to find that they have
also acquired mental debility on the way. We
must encourage them to forsake the trodden
paths, to break tradition when tradition is out-
grown, and to explore the unknown fields.
Individuality ean never be limited to the mech-
anism of public order, either within or without
the school. Life is bigger, it asks for more.
There is only one way to develop strong men,
and that is by helping them to become inde-
pendent thinkers. Electives are the stepping
stones to independent thought, and independent
thought is the threshold of knowledge.
Throughout nature there are many beautiful
pietures of collective and individual effort.

Who can but envy the ideal presented in the life
of the wild honey bee that belongs to the swarm
and works with her companions for a common
purpose. Her coming and going are regulated
by no schedule or master. She goes through
the forests, along the streams, over the mead-
ows, from flower to flower, gathering nectar
from wherever it can be found. Ever going,
ever returning, she not only increases her par-
ticular store, but enlarges that of the swarm.
Beyond and above all these, and all unknown
to her, she gives to mankind greater blessings
in flowers and fruits.
Let us give to the student opportunity an
encouragement to seek truth wherever it can
be found. In bringing truths together he
builds not only for himself but also increases
the common fund of useful knowledge. Be-
yond and above these, he helps to build a great
fund of knowledge which will illuminate life
in the years to come.

HYDRA IN LAKE ERIE
WE seldom think of Hydra as of outstanding
economic importance. However in this con-
nection some interesting data were obtained
by the writer during the summer of 1920 while
staying at a pound-net fishery on the north
shore of Lake Erie near Merlin, Ontario. The
fishery is located about midway between Ron-
deau and Point Pelee, and from it are operated
20 pound-nets in four strings, 5 pound-nets
in a string. The strings are approximately
three miles apart and this would mean about
nine miles from the most easterly string to
the most westerly. In midsummer all the nets
were taken out of the lake, some replaced from
a reserve stock, the others simply reset after
being washed, dried, mended and tarred. This
midsummer cleaning is necessary because of
the algal and other growths which accumulate
on the nets making them heavy as well as
putting considerable strain on the nets, especi-
ally in stormy weather, through the obstrue-
tion of the free flow of water through the
meshes.
All of the nets when lifted in late July and
SCIENCE
445
early August were loaded with a very con-
spicuous brownish-orange growth in addition
to the bright green algal growths. At first
sight diatomaceous ooze or a bacterial produc-
tion was suggested but microscopic examina-
tion showed it to be composed of innumerable
living Hydras. The nets were lifted into the
characteristic flat-bottomed pound-net boats
and brought to the dock. The boats were
anchored 100 to 150 yards from the dock and
the nets dragged through the water to cars on
the dock in order to wash off some of the loose
material, especially mud. In addition to the
mud many Hydras were washed off and these
gave to the water a brownish-orange color quite
distinct from the lighter color of the mud. The
bottoms, seats, ete., of the boats were covered
with Hydras to the depth of from 14 to 4
inches and a quart jar was quickly filled by
simply running a hand along the seats. A
fisherman eight miles to the west and another
seven miles to the east reported Hydra in ap-
parently equal abundance. This means a dis-
tribution of at least fifteen miles along this
part of the shore. The beach is sandy to
gravelly with some large stones. Very little
life was found on the bottom out as far as one
could wade. However out beyond the region
of strong wave action there must be places of
attachment for the Hydras other than the nets
in order to account for the existence of the
species from one fishing season to another,
since in 1920 they had not reached sexual
maturity by the first week in Decemner when
the nets were removed for the season.
Specimens of this Hydra were submitted to
Professor Frank Smith of the University of
Illinois who kindly stated that they without
doubt were Hydra oligactis Pallas although
absolute determination could not be made in
the absence of gonads. He stated that the
large size and numerous buds indicated opti-
mum conditions of food and temperature.
Fishermen had frequently spoken about a
poisoning which often affected them while
handling the nets during the process of clean-
ing and mending. They said this occurred
chiefly after the nets had dried and were
covered with a fine dust which they called tar
dust. No poisoning was observed during this
446
summer but the men stated that their hands
and faces became inflamed and swollen especi-
ally if there were any cuts. The eyes were
often affected also. Lack of time prevented
carrying out any experiments but it seems
quite probable that the poisoning could have
been traced to the Hydras. The dust was com-
posed of dried sediment and organic matter
and certainly must have contained a high per-
centage of Hydra remains.
This account has been written to call atten-
tion to an economic problem in relation to the
fishing industry, which awaits study. There
would appear to be at least four points for
investigation.
(1) The amount of interference and in-
jury caused to the nets by these great growths.
(2) The question of the poisoning of the
fishermen.
(3) Do these Hydra destroy young fish to
any appreciable extent in open water? Beard-

A MOSQUITO ATTRACTANT
Certain facts regarding the possibility of
attracting mosquitoes were disclosed in the
course of experiments made in 1919 which may
have a bearing on mosquito control. Press of
other work has prevented further development
SCIENCE
[Vou. LV, No. 1426
of this project and the following notes are
offered for the consideration of those who may
care to give the matter further attention.
A number of possible attractants were tested.
Among these were crude mixtures of the com-
ponents of perspiration and of blood which
seemed to produce faint, erratic response from
the mosquitoes, but it was found that a degree
of warmth somewhat above that of the sur-
rounding air was highly and consistently at-
tractive to a certain percentage of these in-
sects. Thus a joint of stove pipe placed in the
woods and warmed somewhat by an alcohol
lamp, attracted about as many mosquitoes as
were attracted by persons in the vicinity. It
must be said, however, that in all of our field
tests of this attractant the mosquitoes were
scarce.
In most of the laboratory experiments with
heat Culex pipiens was the species used and
the insects were liberated at will, as bred, into
a cage about 20 x 20 x 15 inches square having
the top and three sides of cheese-cloth, the
bottom of wood, and the fourth side of glass
for observation. The source of heat was water
in a glass flask which was heated by an alcohol
lamp. Air bubbled through this water through
tubing by means of a pump in connection with
a gas bag and was afterwards delivered to a
funnel the open face of which, covered with
cheese-cloth, was placed very near but not
touching the side wall of the mosquito cage. A
thermometer was inserted in this funnel.
As the temperature rose to a point where it
exceeded somewhat that of the surrounding air
a sinister beard-like growth would appear on
that part of the cheese-cloth wall of the cage
covered by the mouth of the funnel. This was
produced by the beaks of the mosquitoes which
were pushed through the cloth with great per-
sistence as long as the current of warm, moist
air was kept within certain limits of tempera-
ture. There seemed to be no specific optimum
temperature but the maximum response oc-
eurred between 90 and 110 degrees Fahrenheit
which represented temperatures from 15 to 30
degrees higher than that of the surrounding
air. When the temperature reached 120 de-
grees less interest was displayed and at 140
degrees the mosquitoes were entirely dispersed.
APRIL 28, 1922]
At temperatures below 85 degrees there was
very little response if any..
A comparatively small number of the mos-
quitoes reacted positively to heat at any one
time; thus with 300 mosquitoes in the cage per-
haps not more than fifteen or twenty would be
attempting to feed at the height of the re-
action. Whether the same individuals were
concerned in each of a series of such responses
or whether various individuals at different
times took part, was not determined.
In nearly all of these experiments, which
were made in an open insectary, no attempt
was made to eliminate the odor of the observer
but in some tests made in a closed room in an
air-tight apparatus the mosquitoes responded
in the usual manner when air was drawn from
outdoors through a long tube. It is interest-
ing to note, however, that when the breath was
bubbled through the water instead of the usual
current of air a decided increase of interest on
the part of the mosquitoes was manifest. The
admixture of various amounts of carbon di-
oxide with the air stream did not increase the
interest over that shown for undiluted air.
In one series of experiments a hole about
two inches square was cut in the lid of each
of two pasteboard boxes which were exactly
alike. These holes were covered with cheese-
cloth and a layer of absorbent cotton was sup-
ported immediately beneath this cloth. In one
box the cotton was moistened with cool water
while in the other it was moistened with hot
water and was supported by a bottle containing
hot water. When these two boxes were ex-
posed in the mosquito cage considerable num-
bers of the mosquitoes would visit the warm
box and attempt to feed while they paid no
attention to the cool box.
Several types of traps in which heat was
employed as an attractant were tested in the
field and mosquitoes could be caught in even
the erudest of these traps but the insects were
also able to escape from all of them, display-
ing decidedly more ingenuity in this respect
than is shown by the house fly. Experiments
with more complicated traps were cut short
owing to the entire disappearance of mos-
quitoes.

It was also found that mosquitoes in cages
fed readily upon a solution of potassium ar-
senite in sweetened water and that this material .
was highly toxic to them. This suggested the
use of such a poisoned bait in heat traps and
traps were also devised in which the insects
might be destroyed upon entering a chamber
containing potassium cyanide. Neither of
these agencies could be tested in the field.

HEINRICH SUTER
On March 17 there passed away Heinrich
Suter, for many years gymnasialprofessor in
Zurich, Switzerland, and a noted student of the
history of Arabic mathematics and astronomy.
For thirty years he was active as a translator
and commentator of Arabic authors. The
twenty years preceding 1892, when his first
distinctly Arabic research was published, were
years of preparation, during which he pub-
lished a history of the mathematical sciences
and a number of papers on mathematies during
the Middle Ages in Europe. Most of his
shorter articles appeared in the Bibliotheca
Mathematica and in Schlomilch’s Zeitschrift
fiir Mathematik und Physik. As regards the
quality of Suter’s extensive studies of Arabic
science it is enough to say that they are highly
respected in an age when higher standards of
historical accuracy are being established in
Europe.
Suter was born on January 4, 1848, at
Hedingen, near Zurich; he studied in Zurich
and Berlin, and took his doctorate in 1872.

THE CALCUTTA SCHOOL OF TROPICAL
MEDICINE
THE British Medical Journal states that the
School of Tropical Medicine and Hygiene and
the Carmichael Hospital for Tropical Diseases
at Calcutta were opened by Lord Ronaldshay,
governor of Bengal, on February 4. In the
issue of December 3, 1921 (p. 957), it was
noted that the School of Tropical Medicine and
448
Hygiene had begun work in the previous No-
vember, when a telegram of congratulation, an-
nouncing that the first lectures had been given,
had been sent by the director, Lieutenant-
Colonel J. W. D. Megaw, I.M.S., to Sir Leonard
Rogers, who played the leading part in the
inception and carrying through of this great
enterprise. In the Journal of April 23, 1910
(p. 1010), the very great advantages which
Caleutta offered for the establishment of a
school of tropical medicine were pointed out;
not only is the variety of clinical cases illus-
trating tropical diseases unsurpassed, but there
is an excellent hospital and medical school,
with a highly qualified staff accustomed to
teaching, and for the greater part of the year
the climate is no drawback. Some eleven years
ago the general scheme for the school of trop-
ical medicine was worked out by Sir Leonard
Rogers, but its subsequent history has been
marked by many delays, not a few of them to
be traced to the war; the foundation stone was
actually laid by Lord Carmichael, governor of
Bengal, in February, 1914. The hospital has
accommodation for about 100 patients, Euro-
pean and Indian, while the school has chairs of
tropical medicine, pathology and bacteriology,
protozoology, pharmacology, serology, public
health, and chemistry, to which appointments
have already been made; professors of hygiene,
entomology, and biochemistry have still to be
appointed. In addition, there are assistant pro-
fessors of the chief subjects, and a number of
special research appointments have been made.
The nucleus of a reference library has been
formed, mainly by gifts from Sir Leonard
Rogers. In the report of the director for 1921
it is stated that classes will shortly be opened
for the diploma in public health of Calcutta
University; classes for the diploma in tropical
medicine have already begun. The director con-
siders that the result of the first year’s working
has entirely removed the doubts and fears which
assailed him when he entered on his responsible
duties. Considerable progress has also been
made in the research laboratories, and reports
have been published of work in connection with
leprosy and kalazar and filariasis, and on the
work of the hookworm laboratory.

SIGMA XI AT McGILL UNIVERSITY
Tue thirty-sixth chapter of Sigma Xi was
installed on April 13 at McGill University,
Montreal. This event marks an epoch in the
society’s progress inasmuch as the MeGill
chapter is the first one to be established outside
the United States. It is expected that there
will soon be other petitions from the Dominion,
and that Canadian institutions will take an
active part in the society’s affairs.
The charter membership of the new chapter
comprises 41, including representatives of both
pure and applied science and medicine. Four
of the members are also fellows of the Royal
450
Society, a somewhat new distinction to come to
Sigma Xi. ;
The installation ceremonies were conducted
by Dr. Henry B. Ward, president of Sigma
Xi, and Dr. Edward Ellery, secretary of the
national organization. After the routine busi-
ness had been transacted, Dr. Ellery delivered
the charge to the new chapter, tracing the his-
tory of the society since its inception at Cornell
in 1886, and outlining the gradual evolution
of its ideals and methods of functioning.
The installation dinner was held in the even-
ing at the Mount Royal Club. The chapter
had as its guests Sir Arthur Currie, principal
of the university; Dr. Gordon Laing, dean of,
arts and chairman of the Graduate School;
Mr. W. M. Birks, of the board of governors;
Dr. Georges Baril, of the Université de
Montréal; Mr. E. J. Archibald, managing
editor of the Montreal Star, and Mr. R. L.
Hamilton, president of the Students’ Council,
as well as Dr. Ward and Dr. Ellery. The toast
to MeGill University was responded to by Sir
Arthur Currie, that to Sigma Xi, by Dr. Ward
in an inspiring address, and that to the new
chapter, proposed by Dr. Ellery, by Dr. F. D.
Adams, vice-principal and dean of applied
selence.
The officers of the McGill Chapter are:
President: Dr. W. W. Chipman.
Vice-presidents: Dr. A. 8. Eve. F. R. S., Dr. J.
Bonsall Porter. i
Secretary-treasurer: Professor R. Del. French.
Executive committee: Dr. H. G. Barbour, Pro-
fessor F. E. Lloyd, Dr. D. A. Murray.
The secretary expresses the hope that no
member of Sigma Xi may pass through
Montreal without giving the McGill Chapter an
opportunity of weleoming him to the city and
of assisting him in every possible way.

tural and mining section, it has large and
important commercial and manufacturing
interests. But it is perhaps chiefly famed for
its scenic attractions drawing every year thou-
sands of tourists by auto and railway from all
parts of the country. The opportunity will be
seized by many who will wish to combine a
pleasure trip to one of the most interesting
sections of the west with the advantages of a
scientific meeting. Here will be met delegates
from the educational centers of the Pacific
Coast as well as from the middle western and
eastern states. Many men active in science
who have not found it possible to attend the
eastern meetings will be at Salt Lake City.
Contacts and relationships will be established
that will widen the horizon of those attending
and prove of lasting benefit.
The hosts of the Salt Lake City meeting
will be the University of Utah, the Utah Acad-
emy of Sciences, the Utah Agricultural College
and the Brigham Young University. Arrange-
ments will be made for the comfort and enter-
tainment of visitors. The meeting will be held
under the auspices of the Pacific Division of
Dr. Barton Warren Ever-
mann, the president of the Pacific Division,
American Association for the Advancement of
Science, will preside at the general sessions
and will deliver the presidential address at the
opening session on Thursday evening, June 22.
He will speak on “The conservation and proper
utilization of our natural resources.”
An outstanding feature of the meeting will
be a symposium on “The Problems of the
Colorado River.” The great reclamation project
which has for its object the utilization of the
waters of the Colorado River has already
attracted wide attention. It is proposed to con-
sider in this symposium the scientific aspects
of the problems involved. The arrangement of
the symposium is as follows:
1. General description of the Colorado River:
Mr. E. C. La Rue, hydraulic engineer, United
States Geological Survey, Pasadena, California.
2. Archeology of the Colorado River Basin:
Professor H. R. Fairclough, Stanford University,
California.
3. Geology of the Colorado River Basin: Dr.
Frederick J. Pack, Deseret professor, department
AprRIL 28, 1922]
of geology, University of Utah, Salt Lake City,
Utah.
4. The conservation of the waters of the Col-
orado River from the standpoint of the Reclama-
tion Service: Mr. Frank E. Weymouth, chief of
construction, United States Reclamation Service,
Denver, Colorado.
5. The interstate and international aspects of
the Colorado River problem: Dr. C. E. Grunsky,
vice-president’ of the Pacific Division, American
Association for the Advancement of Science, San
Franeiseo, California.
The preliminary announcement of the meet-
ing will be issued shortly to members with fur-
ther details of the meeting.
While none of the sections of the national
association will arrange to hold sessions at this
summer meeting the various fields of science
will be represented in the meetings of the affili-
ated societies of the Pacific Division. Those
scheduled to hold meetings at Salt Lake City
are:
The American Physical Society.
The American Meteorological Society.
The American Phytopathological Society, Pa-
cific Division.
The Ecological Society of America.
The Society of American Foresters.
The Cooper Ornithological Club.
The Pacific Coast Entomological Society.

posed route leads by Insalah, the Hogger re-
gion, and Adar of the Iforas, to Bureni on
the Niger, 200 kilometers east of Timbuktu.
The leader of the expedition will be Command-
ant Lafargue, and it will include a dozen mem-
bers representing various government depart-
ments and other interests, among them being a
cinema operator. It is hoped that the difficulty
caused by the evaporation of the motor spirit
in so torrid a climate has been overcome, but
it is pointed out that there is a vast difference
between the exceptional use of motor traction
in this region for a special purpose, which may
be feasible, and its regular commercial use.
Dr. Wauter Lippy, the historian of science,
is delivering a novel series of lectures to the
Industrial Fellows of the Mellon Institute of
Industrial Research, the faculty members of
the University of Pittsburgh, and the students
of the graduate school of the university. The
aim of this series of discourses is to discover
the mental conditions of successful research.
Dr. Libby takes account of certain phases of
individual (or differential) psychology, deals
with some of the more fruitful logical processes,
and considers the means of stimulating the
spirit of scientifie discovery. The illustrative
material is drawn from the records of the
progress of chemistry and other sciences. The
following is an outline of the course of lectures:

Libby devotes a part of each period, say,
twenty minutes of the hour, to a colloquium or
critical discussion of the nature and application
of the subject under consideration. In this
way scientific technic is deliberated upon in all
its aspects. These lectures are being delivered
from 8:30 to 9:30 am. on Tuesday of each
week of the present university semester, in the
Fellows’ Room of the Mellon Institute.

DISCUSSION AND CORRESPOND-
ENCE
POPULAR SCIENCE
To THE Epitor or Science: I am very much
interested in Dr. Slosson’s letter about popular
science writing which appears in Science for
March 3, just received. Since some of my own
information and experience is along this line
it may be worth while for me to make some
additional comment.
I think that I can see a large number of
conditions involved in the fact mentioned by
Dr. Slosson that there is a dearth of popular
science writers in this country, but I shall only
discuss one or two of them. First and fore-
most is the malodorous condition of the popu-
lar science field which for some time has been
so largely and so conspicuously oceupied by
fabricators, exaggeraters, emotionalists, 1gnora-
muses and exploiters that many people of
training and ability hesitate to enter. Fur-
thermore if an entrance is attempted by use
of an informative article of clarity and real
merit the author may have the humiliation of
seeing his work rejected for that of some ir-
responsible clown or gaudy sentimentalist who
is successful in assembling a group of highly
stimulating words (“lots of pep”) which may
or may not have some relation to fact.
Even more important than such discourage-
ment to potential writers is the effect of lax,
inaccurate and falsified statement of scientific
material upon the reading public. I am sure
that for a period of fifty years more hoaxes
have been perpetrated by newspapers in the
name of science than in any other way. As
much as thirty years ago most intelligent
people were suspicious of material presented
by the public press as science. In the last
APRIL 28, 1922]
twenty years this suspicion has been more than
justified and many intelligent readers say they
either do not read or do not believe the stuff
peddled as science by most newspapers. Under
such conditions why should the reading pub-
hie take any interest in popular science writ-
ing? For killing this interest the press ser-
vices, feature syndicates and syndicated news-
papers (aided and abetted by renegade scien-
tists and pseudo-scientists) are to blame rather
than individual newspapers. This is partly
because of commercialized ideas of service, |
partly because of the mass of material handled
and partly because of remoteness from contact
with the reading public.
The lack of interest in scientific matter is
also probably increased to some extent by the
fact which Dr. Slosson mentions as making
it appear strange, 7. e., the increased teaching
of science in our schools. The well informed
student is thereby made more critical of the
material presented. At the same time his par-
ents become more cautious in reading or re-
ferring to it because they fear his ridicule when
some point is raised involving inaccurate or
garbled press reports.
In my own case I admit very freely that I
am fully in sympathy with the man who hesi-
tates to try popular science writing because of
its unsavory reputation. I sometimes have a
very distinct feeling of disgust when I find
an article which I have tried to compose ac-
curately and which I have taken especial pains
to verify, printed in close proximity to one
of the florid, vacuous, or untruthful type. On
the other hand there is a lot of satisfaction
when it gets on the editorial page in dignified
company, as sometimes occurs.
For nearly three years our institution has
been sending out to a number of California
newspapers (our present mailing list is fifty-
three) biological feature articles written by
myself. These have been sent at intervals of
one or two weeks free of charge, partly as a
matter of experiment but mainly as a sort of
university extension activity. We are con-
vineed that the service has educational value
and that it is helping to popularize true
scienee. I have myself been surprised at times
by the interest expressed in certain articles
SCIENCE
455
by people whom I would not have expected
to read them, much less express appreciation
of them. I have personally interviewed about
sixty editors and have had interesting corres-
pondence with others. A large number have
shown such interest in my material that I am
convinced that the general public is interested
in good stuff if properly presented. If eight
or nine out of every ten editors express in-
terest in carefully verified scientific material
written in popular (non technical and simple
and direct) style I am inclined to think that
a similar percentage of intelligent readers
will do so if one will take time to gain their
confidence.
I appreciate the difficulties confronting Dr.
Slosson and Science Service and, like him, I
am impatient at delay but when I think about
how badly the American public has been
served in regard to scientific news I realize
that it will take long and hard work by a lot
of people to get popular science writing on a
basis to inspire confidence. There is always
the risk that one who finds he can write in
popular style will become more interested in
the popular side of it than in the science
(truth telling) side of writing and will become
unreliable, as has often occurred in the past.
Hence it is quite evident that the great need is
not only for writers of popular style, of scien-
tifie training and ability, but also of high
ideals of service which can not be broken down
under the stress of temptation.

TWO NEW WESTERN WEEDS
Durine the past year two plants, which
threaten to become weeds of some importance
in the arid and alkaline regions of the West,
have been received from the western states.
One of these is Bassia hyssopifolia (Pall.)
Kuntze, a member of the family Chenopodi-
ace, originally described from the region of the
Caspian Sea. It apparently has never been re-
corded as occurring in this country. The first
collection was made at Fallon, Nevada, July
28, 1919, by Ivar Tidestrom (No. 10755), and
a considerable amount of material for distribu-
tion has recently heen sent me by F. B. Head-
456
ley, superintendent of the Newlands Experiment
Farm, Fallon, Nevada, which he collected at
that place in August, 1921. Mr. Headley re-
ports that the plant is becoming very abundant
in that section, but that it has not yet invaded
fields of growing crops on good soil, so that it
may not prove to be a serious pest. It makes
a rank growth on soil which is too alkaline for
the usual cultivated crops, and is found in fields
which have received no irrigation as well as in
those which have been frequently irrigated.
Additional specimens have recently been re-.
ceived at the U. S. National Herbarium col-
lected by Professor H. M. Hall (No. 11751) at
Los Bafios, Merced County, California, Octo-
ber 10, 1921, and by Elias Nelson (No. 1002)
at Yakima, Washington, October 3, 1921. Mr.
Nelson reports that this plant has appeared
during the past five years in the Yakima Val-
ley, where it is spreading, and that it is eaten
greedily by stock.
Bassia hyssopifolia is an annual, with much
the habit of Chenopodium album. The flowers
are glomerulate in the axils of small bracts,
and are borne in short or elongate slender
paniculately arranged woolly spikes, at first
usually dense, later elongate and interrupted.
Each of the five perianth segments at maturity
bears on its back a spine incurved into a hook.
A second weed which apparently has not
been reported from this country is Centaurea
picris Pall., also a native of the Caucasus.
Specimens were first recived in May, 1921, from
Mr. C. O. Townsend, who reported that the
plant was said to be a bad weed in the vicinity
of Salt Lake City. Specimens from Idaho
Falls, Idaho, collected by Miss Ayres of the
Idaho Seed Laboratory, have been forwarded
during the past year to Mr. E. Brown of the
United States Department of Agriculture by
Miss Anna M. Lute of the Colorado Seed La-
boratory. Miss Ayres reports that the plant
is becoming a serious pest in some parts of
Idaho. The species has also been collected dur-
ing the past year at Clifton, Kansas, by Mr.
J. W. Head. Mrs. E. P. Harling of the Kan-
sas State Agricultural College, who has in-
vestigated this occurrence, believes that the
species may have been introduced in Turkestan

alfalfa seed. The only North American speci-
men in the National Herbarium is one collected
at Courtney, Missouri, in 1914, by B. F. Bush
(No. 7152).
Centaurea picris is one of the knapweeds or
star-thistles of the Old World, numbering .
several hundred species, some of which have be- -
come weeds in this country, while a few others
are cultivated for their flowers or foliage. It
is a several-stemmed perennial, somewhat to-
mentose or glabrate, with pinnatifid or dentate
lower leaves, smaller and entire upper ones,
and rosy or pink medium-sized discoid heads,
and is especially characterized among the
species known from this country by its in-
volucral characters. The phyllaries are round-
ish to oblong, with greenish bases and scarious
whitish obtuse to acuminate entire or subentire
appendages, those of the inner phyllaries some-
what pilose.
It is evident that both of these plants find in
the arid alkaline regions of the West a habitat
similar to that of their Old World home, and
unless measures are taken for their destruction,
they may become serious pests, as has been the
case in recent years with such plants as the
“Russian thistle’ (Salsola pestifer) and the
prickly lettuce (Lactuca scariola integrata).

CAT-TAIL (TYPHA LATIFOLIA) AS A FEED
EXPERIMENTS conducted on the writer’s farm
demonstrate the practical value of cat-tail as
a feed for hogs. Sixty head were turned into
a three-acre cat-tail swamp, and obtained suf-
ficient nutriment from the rhizomes to keep
them in good flesh for three months. No ill-
ness or digestive disturbance was noted.

in the starchy central core of the typha rhizome
was shown by A. P. Claassen, who estimated
that one acre would yield a total dry weight of
10,792. pounds of cat-tail rhizomes, or more
than two tons of flour, made from the central
core.
Typha may be used as a substitute for high-
priced corn. It would seem that the best time
for feeding would be in the fall and winter, as
the starchy content is likely to be highest then.

SOIL SHIFTING AND DEPOSITS
Mr. Preterson’s article on deposition of soil
in the Palouse area of eastern Washington
and Idaho, which appeared in Science, Janu-
ary 27, 1922, should prove of interest and
value to foresters as well as agriculturists in
this region. The questions naturally arise:
How far is this soil carried into the Bitter-
root mountains, and how does it influence the
character of the soil and vegetation within the
forest areas? The writer’s observations in this
respect may be of interest in this connection.
Dust storms, commonly referred to as
“Palousers,” are of comparatively frequent
occurrence throughout northern Idaho and
northwestern Montana. They accompany high
winds from the west and southwest; they are
well known and despised by housekeepers in
Kalispell, Missoula, Thompson Falls, Libby
and all surrounding towns. The dust pene-
trates into every house and office. When ac-
companied by rain the window panes and
buildings are besmirched with streaks of red
soil. One of these storms in March, 1917, laid
down on the snow within the timbered region
of northern Idaho about 600 pounds of dust
per acre. The dust from that storm hung on
the trees, even at 6,000 feet elevation, along
the Kootenai-Priest Divide throughout the
summer of 1917. Settlers say that dust storms
are common along the Coeur d’Alene, St. Joe
and Clearwater rivers.
The writer has noted ,the billowy soil sur-
face, unmistakably due to surface shifting of
the soil, as far east as Pierce, Idaho, about
SCIENCE
457
eighty miles east of Moscow. The soil is un-
usually deep and fertile and the vegetation is
more profuse, with better growth of timber,
over the larger portion of the Clearwater For-
est in Idaho than occurs on the forests farther
north or on the forests of western Montana.
It is of interest to note that the Clearwater
forest lies directly in the path of the strong
west winds from the arid parts along the
Columbia River, and that Lewis and Clark,
as early as 1806, called attention to the un-
usually deep and seemingly fertile soil in the
Clearwater basin.
These observations lead to the supposition
that the accumulation and shifting of soil on
the Palouse area have been effective in pre-
venting natural establishment of the forest here
in the past, though climatic records indicate
that the area should grow western yellow pine;
and they strengthen the belief that the un-
usually good growth of timber, profuse vegeta-
tion, and deep soils on certain parts of the
western slopes of the Bitterroot mountains
in Idaho, are due partly to the fact that soil
is carried in by the westerly winds from lava
plateaus along the Snake and Columbia rivers.

QUOTATIONS
AN INTERNATIONAL LANGUAGE
THERE is an increasing demand among scien-
tifie men for international agreement as to the
choice of a universal auxiliary language. After
a long struggle, many of the fundamental tools
of thought have been unified. All nations now
use the same system of numbers, Arabic
numerals, measurements of latitude and longi-
tude, mathematical symbols, chemical formule,
and, at least in science, the metrie system.
But language, the master-key to thought and
the vehicle of communication, remains under
the curse of Babel. Were it possible by acquir-
ing a second language in addition to the natal
language to convey ideas to fellow-workers in
every part of the world and to receive their
ideas, one of the greatest barriers to the prog-
ress of science would be broken down. Time
and money would be saved, overlapping of
458
effort prevented, and precision of ideas would
be assisted.
For many years there have been efforts to-
wards the establishment of an international
language, but chiefly by private persons or by
associations formed directly for that purpose.
Since 1919, however, governmental, scientific,
and international bodies have given serious
attention to the practical possibilities. At the
meeting of the International Research Council,
held in Brussels in the first summer after the
war, a committee was appointed to investigate
and report on the general problem of an inter-
national auxiliary language, and to cooperate
with similar bodies established or that might
be established for the same purpose.
The Section for Education of the British
’ Association at the Bournemouth meeting ap-
pointed a committee which reported to the
Edinburgh meeting last autumn. The Amer-
ican Association soon afterwards took a sim-
ilar step, and its report was presented to the
meeting at Toronto last December. The French
and Italian Associations have also appointed
committees, but as yet these have not issued
reports. The delegates representing 12 states
presented a resolution in the Assembly of the
League of Nations last September taking the
definite step of recommending Esperanto, and
hoping that the teaching of that language
would be made more general in the whole
world, so that children of all countries might
know at least two languages.
In accordance with the procedure of the
league, this motion was referred to a committee
under the chairmanship of Lord Robert Cecil.
The committee was of the opinion that the
question, in which “an ever-increasing number
of great states’ was interested, should be
studied attentively before being dealt with by
the Assembly. Accordingly, it is being studied
by the secretariat. The British Association
committee went further, and definitely recom-
mended the choice of an artificial language,
but hesitated to decide between those which
have been invented. The American Association
recognized the “need and timeliness of funda-
mental research on the scientifie principles
which must underlie the formation, standardiza-
tion, and introduction of an international

auxiliary language,’”’ and recommended further
study.
These various bodies are free from the sus-
picion of advocating serious study of what
might be regarded as a “fad.” It is fair to
accept their action as witness to the urgency
of the problem. There is also evidence of their
agreement that an auxiliary language, if it is
to serve its purpose, must receive almost uni-
versal adoption.
The only suggestions which have received
sufficient support to be ranked as serious ean-
didates are Latin, English, Esperanto, and Ido.
Latin was at one time the common medium of
many nations and has retained a wide currency,
directly in religion, less directly in some
branches of science, and as the basis of the
Romance languages. It is elegant and concise,
has a definite system of forming new com-
pounds and derivatives, and, as a dead lan-
guage, its roots have unchanging significance.
But its grammar is difficult; it has many ex-
ceptions and irregularities. The revival of
Latin would require the coining of a very large
number of new words.
English is widely used and is spreading rap-
idly; its grammar is relatively simple and its
vocabulary is rich. But the choice of one
among many widespread living tongues would
excite a just jealousy. Its spelling is chaotie,
and its pronunciation difficult and various.
Moreover, a living language reflects the chang-
ing activities and emotions of the people who
use if in literature and in daily speech, and is
therefore unsuited as a vehicle for the cold
and precise exchange of international knowl-
edge.
The language Esperanto has
already made great progress as an interna-
tional auxiliary tongue; it has held 12 inter-
national congresses in different countries; it is
taught in sehools in Geneva, Breslau, Milan,
Czecho-Slovakia, and Bulgaria. Its grammar,
pronunciation, and method of word-building
are simple, scientific, and easy to acquire, and
its root-words have been carefully selected. Ido
claims to be a later and improved form of
Esperanto; hitherto it has had a smaller vogue,
but in appearance and sound it is more attrac-
tive.
invented
Aprit 28, 1922
The balance of advantages seems to lie with
the selection of either Esperanto or Ido or some
modification of them recommended by experts
on language. The vital requirement is that the
auxiliary language should be kept auxiliary,
the vehicle of formal statement. If it should
become a language of common speech, of emo-
tion, or of literature it will at once fail of its
purpose and be only an additional linguistic
burden.—London Times.
SPECIAL ARTICLES
ATOMIC STRUCTURE
Tere has been considerable discussion in
the literature, during the past few months, of
the Lewis theory of atomic structuret and
Langmuir’s extension of it to the heavy ele-
ments.” In 1919 and 1920 the writer worked
out a somewhat different extension of this
theory. Jor various reasons its publication has
been delayed, but in a few months a paper
deseribing it in some detail is to appear. Be-
cause of this delay, a short outline of the
theory may not be out of place here.
The number of electrons in each shell of the
lighter atoms is the same as in the original
Lewis theory. It is assumed, however, that
the fifth, sixth, seventh and eighth electrons in
the second and third shells pair off with the
first four, the distance between the electrons in
each of these pairs, and also in each pair
formed by bonding between atoms, being much
less than the distance between pairs. These
shells are therefore tetrahedra of pairs instead
of cubes of single electrons.* The electrons in
each shell (after the second) tend to be placed
opposite the centers of the faces of the imag-
inary polyhedron formed by the electron
groups in the underlying shell. If a certain
shell is a tetrahedron, the next shell out will
also be a tetrahedron; if the inner shell is a
cube, the outer shell will be an octahedron (six
points, eight faces); and if the smaller shell is
an octahedron, it will be surrounded by a tetra-
hedron—four of its eight faces then being
oecupied—or by a eube.

When the nuclear charge becomes sufficiently
great, the same forces which cause pairing of
electrons in nitrogen result in the formation of
triplets in the inner shells of the heavier
atoms. The type of force between electrons
necessary to account for these phenomena is
discussed in my longer paper and will not be
considered here. As one after another of the
outer electrons are drawn into an inner shell to
form triplets, the remaining pairs are pushed
further and further from the nucleus. This
may result in rearrangement of the kernel
structure, as indicated in the examples of
atomic structure given below. Often, in dif-
ferent environments, different kernel structures
are stable, some having more valence electrons
and fewer triplets than others, ete.
The structures resulting from the applica-
tion of the foregoing ideas I shall represent by
means of formule, in which the first paren-
thesis represents the nucleus and indicates its
charge, the remaining parentheses each repre-
senting a shell of electrons, in order from the
nucleus out. The number of electron-groups
and the number of electrons in each group are
indicated for every shell, except (in some
eases) the valence shell. Formule for atoms

These and similar formule for the other ele-
ments express very satisfactorily their known
chemical, physical and crystallographic prop-
erties. By applying this theory to erystal
structures, it has been found possible to deter-
mine the arrangements of electrons in nearly
all erystals for which the arrangements of
atomic centers were already known, and also
the atomic and electronic structures in many
cases in which even the atomic marshalling
was previously unknown. These structures
furnish incontrovertible proof that this theory
of atomie structure, fundamentally and in
many of its details, is correct.
An important part of the theory is the idea
that a single bond may be formed not only by
the attraction between two atoms, each of which
contains an unpaired electron in its valence
shell, the two single electrons forming a pair,
but also by the attraction of an atom containing
a “lone electronpair’—one not acting as a
bond—for another capable of holding on to
this lone pair. The following are typical re-
actions of this type:

In the last two cases the lone pairs of the
nitrogen atoms become bond pairs, assuming
positions at octahedron corners opposite the six
faces of the distorted cube of the cobalt kernel
and at tetrahedron corners opposite the four
previously unoccupied faces of the zine kernel
octahedron (or, what is the same thing, oppo-
site the four faces of the zine kernel tetra-
hedron). We thus have an entirely satisfae-
tory picture of Werner’s “auxiliary valencies”
and “coordination numbers.” In some cases
(e. g., in Ag(NH.,)*) all the faces of the kernel
polyhedron are not occupied. (In the silver
iodide erystal, each silver kernel is surrounded
by four electronpairs at tetrahedron corners,
showing its true coordination number to be
four.)
This theory has not yet been applied to the
explanation of spectra; nor is it possible to
give the exact positions of the electrons in each
atom. These positions may in fact be merely
the centers or foci of electronic orbits. In
these and other respects the theory is still
incomplete.

A SIMPLE BUBBLING HYDROGEN
ELECTRODE
Tue electrode described in this paper is the
result of an attempt by the writer to combine
the principles of the bubbling type of elec-
trode with simplicity of construction and the
necessity for only a small amount of solution.
That this has been accomplished, seems to be
apparent from a study of the accompanying
diagram and the behavior of the electrode in
numerous tests.
Four models similar to the one shown in the
diagram were constructed by the writer and
compared with each other and a Bailey elec-
trode. Various standard buffer solutions were
tested and it was found that all electrodes gave
results that agreed within .3 of a millivolt,
which was the limit of accuracy of the gal-
vanometer in the set up.
While the models constructed by the writer
require only about 1.5 ec. of solution, there
seems to be no good reason why, with proper
APRIL 28, 1922]
precautions, they can not be constructed for
smaller amounts of solution. This can be accom-
plished, not by a smaller model of the same
shape, but by making the bottom of the elec-
trode vessel more conical in shape and taking
particular precautions in sealing the electrode
as near the base of the vessel as is conve-
niently possible. It is not desirable to materially
decrease the diameter of the upper portion of
the electrode vessel, because in so doing, the
bubbling process is seriously interfered with.
CONSTRUCTION AND OPERATION
The electrode vessel H was made by sealing
a short piece of glass tubing to an ordinary
three inch soda-lime tube. The glass tube was
then bent into position to make the side arm, A.
The electrode proper, which consists of a piece
of platinum foil, was sealed as near the base
of the main vessel as possible. The protruding
end of the foil was bent into a loop and par-
tially embedded in sealing wax to give added
mechanical strength. The rubber stopper, D,
is used to prevent the rapid diffusion of air
into the electrode vessel. The support, S,
shown in the diagram by means of dotted lines,
was made from a No. 12, two-holed rubber
stopper by cutting out the portion between
the holes.
After platinization of the electrode, about
1.5 ¢.e. of the solution to be tested are put

into the electrode vessel, H. Purified hydrogen
is bubbled through the solution by way of the
side arm, A. Usually, about three minutes of
bubbling are required for saturation.
The diagram shows the electrode in position
for a measurement. C represents the side arm
of the calomel electrode, V, a vessel containing
a saturated KCl solution, and B, a tube filled
with saturated KCl and plugged at the smaller
end with filter paper to prevent the too rapid
siphoning of KCl from VY.
When properly constructed, this electrode
possesses the following features, which should
make it applicable for quite general use:
1. Simplicity of construction.
2. Ease of operation.
3. Requires only a very small amount of
solution for a determination.

Ranson’s Anatomy eu
of the Nervous System
Dr. Ranson presents anatomy of the nervous system from the dynamic rather than the
static point of view; that is to say, he lays emphasis jon the developmental and functional
significance of structure. The student is thus led at the very beginning of his neurologic
studies to think of the nervous system in its relation to the rest of the living organism.
This method not only makes the subject interesting, but makes more easy the correlation
of the various neurologic courses. An outline for a laboratory course in neuro-anatomy
is included. The text is fully illustrated, there being 260 illustrations, some of them in
colors.

400 pages, 5%2x8%%, illustrated with tables, charts, and 55 line cuts. Fifth revised, enlarged edi-
tion. Price, silk cloth binding, $4.50.
The fifth edition has been completely revised, making practically a new book. All obsolete
methods have been eliminated and only tried and proven methods as outlined in the course at
Cambridge have been given. All the modern methods in biochemistry are given in detail. The
procedures are not copied from other works, butare the result of first-hand acquaintance with the
subject matter. The author has prepared his text at the laboratory bench, step by step—any
method that seems doubtful or difficult of attainment has been eliminated. While the book is
practical, there is reference to theory and to the actual significance of results. A valuable book
for the student, practitioner of medicine, research worker, for one who seeks for accurate and
full descriptions of biochemical researches, and for students in agricultural laboratory work,. and
in the study of animal nutrition.
Physiological Abstracts, August, 1919
“This completely revised and enlarged edition of the author’s well-known textbook should receive a gen-

AN INTERMEDIATE TEXTBOOK OF
Physiological Chemistry
By C. J. V. PETTIBONE, Ph.D., Assistant Professor of Physiological Chemistry in the Medical School of the
University of Minnesota.
328 pages, 6x9, with illustrations. Price, silk cloth binding, $3.25.
The plan of this book is to cover as completely as possible in a brief but adequate manner the
general field of physiological chemistry, so that the student or physician may obtain a clear idea
of the properties of the compounds which are physiologically important—carbohydrates, fats,
proteins, inorganic material, of the processes of digestion, and the action of enzymes, the com-
position of some common foods and important tissues, the composition and analysis of the urine,
and lastly, a review of the present status of metabolism, including its more modern aspects. The
average physiological chemistry at present available is so large that the student or physician is
lost in a mass of details or conflicting evidence. The author has aimed in this volume to
set forth the present status of physiological chemistry as clearly and concisely as possible, in the
belief that a large number of people will find a book of this type useful and valuable for acquir-
ing or refreshing information in this important field. The appended laboratory work is arranged
to cover the important phases of the subject, including the quantitative analysis of the urine.
Now the required text in leading medical schools.

HESPEROPITHECUS, THE FIRST AN-
THROPOID PRIMATE FOUND
IN AMERICA
Ir is hard to believe that a single small
water-worn tooth, 10.5 mm. by 11 mm. in
crown diameter, can signalize the arrival of
the anthropeid Primates in North America in
Pliocene time. We have been eagerly antici-
pating some discovery of this kind, but were
not prepared for such convincing evidence of
the close faunal relationship between eastern
Asia and western North America as is revealed
by this diminutive specimen. The entire credit
for the discovery belongs to Mr. Harold J.
Cook, consulting geologist, of Agate, Nebraska,
who has been contributing for many years to
our knowledge of the extinct fauna of Ne-
braska through both his discoveries and his
writings. He wrote to the present author
(February 25, 1922):
I have had here, for some little time, a molar
tooth from the Upper, or Hipparion phase of the
Snake Creek beds, that very closely approaches
the human type. It was found associated with
the other typical fossils of the Snake Creek, and
is mineralized in the same fashion as they are.
I sent a brief description of this to Professor
Loomis a short time before the Amherst meeting
of this year, with a request that it be read at
that time, if opportunity offered. The manuscript
was returned to me here immediately after the
meetings, but with no notation as to whether it
was read or not, or presented at that time in any
fashion.
Inasmuch as you are particularly interested in
this problem and, in collaboration with Dr. Greg-
ory and others, are in the best position of any one
to accurately determine the relationships of this
tooth, if it can be done, I will be glad to send
it on to you, should you care to examine and
study it. Whatever it is, it is certainly a contem-
porary fossil of the Upper Snake Creek horizon,
and it agrees far more closely with the anthropoid-
human molar, than that of any other mammal
known.
464
On receiving the tooth, the author tele-
graphed (March 14, 1922): “Tooth just ar-
rived safely. Looks very promising. Will
report immediately.” A letter followed the
same day:
The instant your package arrived, I sat down
with the tooth, in my window, and I said to my-
self: ‘‘It looks one hundred per cent. anthro-
poid.’’ I then took the tooth into Dr. Matthew’s
room and we have been comparing it with all the
books, all the casts and all the drawings, with the
conclusion that it is the last right upper molar
tooth of some higher Primate, but distinct from
anything hitherto described. We await, however,
Dr. Gregory’s verdict to-morrow morning; he cer-
tainly has an eagle eye on Primate teeth. . . . We
may cool down to-morrow, but it looks to me as if
the first anthropoid ape of America had been
found by the one man entitled to find it, namely,
Harold J. Cook!
On March 22, 1922, the author wrote:
We believe we have found another one of the
teeth, very much worn, of the same animal, which,
so far as it goes, is confirmatory. The animal is
certainly a new genus of anthropoid ape, probably
an animal which wandered over here from Asia
with the large south Asiatic element which has
recently been discovered in our fauna by Merriam,
Gidley and others.

much worn.

The tooth arrived with the following label:
One Molar Tooth, ?Anthropoid, No. HC425,
Collection of Harold J. Cook, Agate, Nebraska.
Found in Upper Phase of Snake Creek Beds,
Typical Locality, in position in gravels with other
fossils.
Following the examination by Dr. William
D. Matthew and the author, who determined
the tooth as a second or third upper molar of
the right side of a new genus and species of
anthropoid, the tooth was submitted to Curator
William K. Gregory and Dr. Milo Hellman,
both of whom have made a special study of
the collections of human and anthropoid teeth
in the American Museum and the United States
National Museum. They reported (March 23,
1922) as follows:
1. Such a degree of wear is very rarely seen on
m, and in view also of the marked difference in
SCIENCE
[Vou. LV, No. 1427
form of m%, we rather incline to the opinion that
it is an m2. 2. The kind of wear shown in this
tooth, which has an evenly concave surface (with-
out humps representing the para- and metacones),
has never been seen in an anthropoid tooth, and
we are of the opinion that even in very old chim-
panzees the outer half of the crown will be un-
evenly worn. 3. The nearest in point of wearing
surface is the supposed m2? attributed to Pithe-
canthropus, also in form of roots. The strong
hypocone in ‘‘ Pithecanthropus’’ and the absence
of hypocone in the new specimen is not positively
diagnostic, in view of the immense differences in
the hypocone, both in apes and man. 4. On the
whole, wwe think its nearest. resemblances are with
‘* Pithecanthropus’’ and with men rather than
With apes.
On the basis of these very careful studies,
the author decided to make this tooth the type
of the following new genus and species:
Hesperopithecus haroldcookii,t new species
This second upper molar tooth is very distant
from the gorilla type, from the gibbon type, from
the orang type; among existing anthropoid apes
it is nearest to m2? of the chimpanzee, but the
resemblance is still very remote. It is excluded
from close affinity to the fossil Asiatic anthro-
such as Dryopithecus .punjabicus,
Paleopithecus sivalensis, and Sivapithecus, re-
cently related to the human stem by Pilgrim. Its
transverse diameter of 11 mm. is greater than its
anteroposterior diameter of 10.5 mm. In the cor-
responding human tooth, m?, of an American
Indian, with which it is compared in Fig. 2, the
transverse diameter is 12.5 mm., the anteropos-
terior diameter is 11 mm. Thus the proportions
of the molar crown of the Hesperopithecus type
are about the same as those in the Homo sapiens ©
mongoloideus type. There is also a distant human
resemblance in the molar pattern of Hespero-
pithecus, as very skilfully portrayed (Fig. 1)? by
the artist, Mrs. L. M. Sterling, to the low, basin-
shaped, channeled crown in certain examples of
Homo sapiens. But the Hesperopithecus molar
cannot be said to resemble any known type of
human molar very closely. The author agrees
with Mr. Cook, with Dr. Hellman, and with Dr.
Gregory, that it resembles the human type more
closely than it does any known anthropoid ape

type; consequently it would be misleading to speak
of this Hesperopithecus at present as an anthro-
poid ape; it is a new and independent type of
Primate, and we must seek more material before
we can determine its relationships. It is cer-
tainly not closely related to Pithecanthropus
erectus in the structure of the erown, for Pithe-
canthropus has a single, contracted crown in which
the superior grinding surface has a limited crenu-
lated basin, whereas Hesperopithecus has a widely
open crown with broadly channeled or furrowed
margins, and a postero-internal crest suggesting
the hypocone of a higher Primate form. The dis-
position of the roots in Hesperopithecus, in Homo,
in Pithecanthropus, is shown to be very broadly
similar in comparative Fig. 2. The Hesperopi-
thecus molar is three-fanged, the postero-external
fang having been broken off in the type; the
internal fang shows a median internal groove
and a tendency to a deep external groove on the
outer side.
Since 1908 there has been in the American
Museum collection from this same horizon an-
other small water-worn tooth, discovererd by
Dr. William D. Matthew. The specimen. be-
longed to an aged animal and is so water-worn
that Dr. Matthew, while inclined to regard it
as a Primate, did not venture to describe it.
It now appears, from close comparison with
the type of Hesperopithecus, to be closely re-
lated generically, even if it is not related spe-
cifically. The greatly enlarged drawing (Fig.
3), reproduced to the same seale as that of the
type above described, shows that the molar
pattern is fundamentally similar. The crown
differs in its much more triangular form and,
were it not for its extremely worn surface, we
should unhesitatingly pronounce it as a third
superior molar; it has, therefore, been given
this position provisionally in the diagram; it
seems to confirm the opinion of Gregory and
Hellman that the type of Hesperopithecus is a
second superior molar.
The geologic age of these two specimens is
now believed to be the same as that of Thou-
sand Creek, Nevada, and Rattlesnake, Oregon,
among the fauna of which Pliohippus is very
abundant and varied; it also contains Tlingo-
ceras and other strepsicerine antelopes of
Asiatic affinity; it is the last American fauna in

MEDALS AND DINNER OF THE NA-
TIONAL ACADEMY OF SCIENCES
At the annual dinner of the National Acad-
emy of Sciences, held at the Hotel Powhatan on
Tuesday evening, April 25, 1922, two medals
were awarded.
The J. Lawrence Smith Medal was bestowed
upon Dr. George P. Merrill, curator of geology
at the United States National Museum. This is
a gold medal of the value of $200, from a fund
established in 1884, as a reward for “original
investigation of meteoric bodies.” But because
investigators in this field are so rare it has not
been given since 1888. Dy. Whitman Cross,
in his speech presenting the medal, pointed out
that Dr. Merrill had continued to carry on the
work of his predecessor, J. Lawrence Smith,
on meteorites by the application of modern
methods of analysis. The earlier analyses of
meteorites were not always to be relied upon,
and Dr. Merrill in his long years of research
has been able to show that some of the elements
previously reported as having occurred in
meteorites are absent and, at the same time, he
has extended the list of elements and com-
pounds that do exist in these bodies. Among
other minerals he has found a ealeium phos-
phate similar to apatite, which has been named
in his honor Merrillite. Dr. Merrill also has
discovered evidences of metamorphism in mete-
orites, cases where a mineral structure has been
broken up and the fragments later fused to-
gether like the conglomerates found in igneous
rocks in the earth’s erust.
Dr. Merrill in receiving the medal said that
meteorites had in all ages attracted a great
deal of popular interest. In the earliest times
they were worshipped as divine and nowadays
the newspapers give great attention to any
meteoric fall. Yet few scientists have made
them the subject of concentrated and long-
continued study. In his work, Dr. Merrill said
466
he had tried to keep his feet upon the earth
as though his shoes had leaden soles and to
leave to others premature speculation as to the
origin of these bodies. It is evident from their
composition that they come from regions where
there was no air, for they contain iron, both in
a free state and in compounds that are not
stable in the presence of oxygen. From their
structure it is evident that some have under-
gone secondary igneous changes. In conelu-
sion, Dr. Merrill quoted the verse, “All my
dreams come true to other men,” and said that
he would leave the developments and deduc-
tions from his work to future investigators and
“may all my dreams come true to other men.”
The address bestowing the Daniel Giraud
Elliot Medal for the year 1920 was made by
Dr. Henry Fairfield Osborn, of the American
Museum of Natural History, New York City.
This medal is intended to be awarded every
year for contemporary contributions to zoology.
Previous awards were made to F. M. Chapman,
C. W. Beebe and Robert Ridgway. Dr. Osborn
sketched the history of paleontology from the
time when Cuvier first announced the law of
correlation. But the ability of the biologists
to restore an extinct animal from a single bone
was exaggerated and for a time such general
theoretical work fell into disrepute. The great
American paleontologists, Leidy, Cope and
Marsh, limited themselves mostly to deserip-
tion. But now again the time has come when
general principles and relationships may be
founded upon a more substantial basis. Among
the young investigators who are taking up this
work is Professor Othenio Abel, of Vienna,
who has undertaken a general study of the
causes of evolution. His guiding thought is
that morphology depends upon physiology and
that to understand a form we must know its
function. Professor Abel pursued his studies
even during the war when his family was in
such distress that he had to send out his
children to friends for food, and in 1920 he
produced an inspiring work, entitled Methoden
der Paleobiologischen Forschung.
In the absence of Professor Abel the medal
was received by Edgar L. G. Prochnik, Aus-
trian chargé d’affaires, who said that all Austria
would rejoice over this honor done to one of

her citizens. Conditions in Austria are exceed-
ingly hard at present on account of the curtail-
ment of Austria’s resources and it is felt that
the future of Austria lies in the mental power
of her sons. The Austrian scientists are deter-
mined to bring their country to the rank which
she occupied in science and art previous to the
war. The disposal of this medal was another
proof that science was not limited in its scope
to ereed or nationality. Professor Abel serves
in the ranks of science, the peace maker.
President Walcott, in handing over the medal
to the representative of the Austrian Legation,
said that the award would earry with it an
honorarium which was to be forwarded to Pro-
fessor Abel.
Next, Dr. Vernon Kellogg, permanent secre-
tary of the National Research Council, was
called upon to tell something of the work and
plans of that institution. The National Re-
search Council, he said, was the child of the
National Academy of Sciences, born in the
tempestuous times of the war. The child had
grown with amazing rapidity and had mani-
fested the characteristic virtues and defects of
lusty youth. Some of its parents—the use of
this unconventional plural is justified by the
collective parenthood—do not know whether to
be proud of it or uncomfortably disturbed by it.
The motto of the National Research Council
is “cooperation and organization.” The latter
word was looked upon with disfavor and even
suspicion by some scientists, but, rightly under-
stood, as the council interprets it, there was
nothing to fear from it. He had recently been
reading the reports of the visits that had been
paid by members of the council to 150 universi-
ties, colleges and other laboratories. In all
these were found men earnestly engaged in re-
search, often under disheartening conditions
and in isolation. The National Research
Council can aid and encourage these scattered
and ill-equipped scientists to work out their
plans in a concerted way. Nothing shall inter-
fere with the individual freedom and initiative
which are the main strength of scientific en-
deavor. Apart from the endowment and build-
ing fund, the National Research Council had
raised over a million and a half dollars, which
was being expended in promoting research
May 5, 1922]
work in various lines. Plans for the new
building had been exhibited at this session of
the academy. This building will cost about
$1,300,000, this money being provided by the
Carnegie Corporation, and $200,000 had been
provided by a seore of private donors for the
purchase of the ground. The edifice will be
worthy of standing in the group of patriotic,
philanthropic, international and memorial
structures, and here the National Academy of
Sciences and her daughter, the National Re-
search Council, may live together in peace and
happiness.
The president then asked Dr. William H.
Welch to speak on the new School of Hygiene
and Public Health founded at Johns Hopkins
University and endowed with six millions
from the Rockefeller Foundation. Dr. Welch
said that the prevention of disease in communi-
ties as distinct from the cure of disease indi-
vidually was comparatively a new profession.
The beginning of the public health work may
be traced back to the seventeenth century, when
three great discoveries were made. One was
Captain Cook’s success in preventing scurvy in
his long voyage in the Pacific by the use of
vegetable vitamines. The second was the dis-
covery of the cause of ‘Devonshire colic,”
which was found to be due to lead poisoning
from the drawing of cider through lead pipes.
The third was the introduction of vaccination
for smallpox. The Napoleonic wars set back
work in this direction as in others, but in the
great reform year of 1848 the English Parlia-
ment passed the Public Health Act. Then
began a campaign directed against filth and
for sanitation, water supply and sewage dis-
posal. Now with our new knowledge of the
causes of infection and epidemics, public health
can be guarded as never before. Yellow fever
has been swept from its old haunts, malarial
fever can be controlled and typhoid has become
so rare that it is difficult to teach it for want of
cases.’ In Baltimore last year a single death
from typhoid aroused great excitement among
the students who were eager to attend the
autopsy as the only opportunity they had to
become acquainted with this disease. The new
school is to be composed of men and women
who are to make the prevention of disease the
SCIENCE
467
primary aim of their life work. There are four
members of the National Academy of Sciences
in the faculty of the School of Hygiene and
Public Health.
At the close of the evening Dr. Hendrik
Anton Lorentz, of the University of Leiden,
was asked to speak and responded with charae-
teristic geniality. He recalled his visit to the
United States sixteen years ago and told how
glad he was to accept the invitation of the
Carnegie Institution of Washington and the
California Institute of Technology, Pasadena,
where he has been lecturing. Now on the eve
of departure he expressed his gratitude for the
kindness that had been showered upon him in
various parts of the United States which was,
he felt, more than he deserved and was, as he
had discovered in some eases, due to the fact
that he was taken for the Viennese surgeon,
Dr. Lorenz. Everywhere he found earnest
young men engaged in research which prom-
ised great things for the future of science in
America. He found nothing to criticize, but
took the opportunity of suggesting that per-
haps the strenuous life and feverish activity of
Americans might be benefited by somewhat of
the Dutch restfulness of his own land.

THE EDWARD C. PICKERING
MEMORIAL
THE wonders of the sky present such a
fascinating appeal to the general public that
large numbers of telescopes are sold each year
to the amateur who with keen delight views the
marvels of Saturn’s rings, the everchanging
appearance of Jupiter and his satellites, and
the glories of the nebula of Orion. These and
many other objects are observed with the great-
est of eagerness, and books on descriptive
astronomy are bought and are read with great
avidity. The pleasures brought by the new
telescope are all the more enjoyed if the instru-
ment arrives during the summer season. Then
it may be taken out into the garden or on to
the roof top and the pleasure is unalloyed by
biting winds, cold hands or freezing feet. With
the coming of autumn and winter the telescope
is used less frequently, and the warmer weather
of spring and summer is looked forward to
468
with anticipation. (The writer of this article
looks back with anything but the keenest of
joy to working for thirteen hours at night at
the Yerkes Observatory with the thermometer
at twenty-six degrees Fahrenheit below zero).
Very frequently the keenness of the astro-
nomical thrills becomes gradually dulled, the
small telescope has not sufficient power to show
the more remarkable objects in the sky, clouds
and cold weather interfere with observing—
and soon the telescope is brought out but sel-
dom, and finally is offered for sale.
Many of these amateur star-gazers might
have had their interest continued if only their
work at night could have had some object other
than personal pleasure. The American Asso-
ciation of Variable Star Observers has been of
very great value to astronomy by organizing
the owners of two-, three-, four- or five-inch
telescopes and showing them how they can co-
operate with the professional astronomer using
larger telescopes to observe the class of objects
in the sky known as variable stars. As their
name signifies, these stars vary in_ bright-
ness, sometimes being bright, sometimes much
fainter. There are more than three thousand
of such stars known in the the sky. The varia-
tions of some stars like Betelgeuse, 8 Lyre or
6 Cephei can be followed by the naked eye,
some of the stars at minimum brightness can
be seen with a five-inch telescope, while others
become so faint at minimum that they are
almost or quite invisible in the largest telescope
in existence. Some of these variables have a
period from maximum to minimum which is
quite short, measured by an interval of a few
hours or a few days in length, some of the
periods are measured in hundreds of days.
Some of the periods are quite regular, some
are very irregular. The well-known Algol
changes in brightness by one component eclips-
ing ‘the other. There are other stars like
SS Cygni, V. Geminorum, and SS Aurige that
are normally faint, and suddenly and for some
reason for which as yet we have no adequate
explanation greatly augment their brillianey,
the last of the three named above
may increase its brightness one hundredfold in
twenty-four hours. There are thus many varie-
ties of variable stars most of which need careful
stars
SCIENCE
[Vou. LV, No. 1427
and systematic observation, and consequently
an observing program can be chosen which
can be adapted to the aperture of the telescope
used.
Largely through the enthusiastic efforts of
Wm. Tyler Olcott of Norwich, Conn., the
American Association of Variable Star Ob-
servers (or the A. A. V. S. O.) was organized
in 1911 with seven observers. In ten years the
membership has grown to three hundred, and
the total observations made has the amazing
number of 120,000. The present plan of the
A. A. V. 8. O. is that its members are observing
systematically the changes in brightness of
more than three hundred stars of long period.
The stars under observation can be followed
until with diminishing brightness they become
invisible with the small apertures employed.
These stars, however, can still be seen with
telescopes of larger size in the hands of the
professional astronomer. By a plan of coop-
eration, therefore, the members of the
A. A. V. 8S. O. can observe the variables when
bright while Harvard with its twelve or fifteen-
inch telescope and the McCormick Observatory
with its still larger aperture of twenty-six
inches can observe when faint, and thus the
stars can be kept under almost continual ob-
servation, except when the stars are too near
the sun. Each month each observer sends his
observations to Harvard College Observatory
where the observations are collected together
and are then published in Popular Astronomy.
This immediate publication is of great value in
keeping alive the interest of the amateur for
each observer can see that his observations are
of value in fixing the brightness of the stars
and even the beginner can experience the thrill
of finding that his observations perhaps fit in
beautifully with the magnitudes determined by
observers of greater skill.
Professor Edward C. Pickering, the late
director of Harvard College Observatory, was
keenly enthusiastic about the work of the
A. A. V. S. O. for he recognized the very great
value of this organization. And now to per-
petuate its work and to increase its value to
astronomy the Association of Variable Star
Observers is asking for an endowment to bear
the name, the Edward C. Pickering Memorial.

be entirely
none of it
The income from this fund is to
devoted to variable star research,
being required for “overhead” or for equip-
ment. Through an arrangement with Pro-
fessor Pickering’s successor, Dr. Harlow
Shapley, Harvard College Observatory is to
put the second floor of its library building at
the disposal of the A. A. V. 8. O. for its offices,
and is to allow the use of one of the domes on
the observatory grounds to house the largest
telescope owned by the association, that re-
cently aequired through the generous gift of
Mrs. C. A. Post of Bayport, L. I.
Professor Pickering was so well known to
members of the A. A. A. 8. and to readers of
Science that it is felt that many will wish to
contribute to such a worthy cause as the Ed-
ward C. Pickering Memorial. Contributions
should be sent to Wm. Tyler Olcott, Norwich,
Conn., or to Leon Campbell, Harvard College
Observatory, Cambridge, Mass.

J. D. MITCHELL
Mr. J. D. Mitcuen died at Victoria, Texas,
on February 27, 1922.
Some years ago when the writer was about
to go to Texas for the first time, he made the
rounds of a number of scientific offices at
Washington to obtain such information as he
could about the natural history of Texas.
Wherever he went, whether to entomologists,
ornithologists, ichthyologists or botanists, the
same advice was given. That was to go to
Victoria and see Mr. J. D. Mitchell. A man
whose knowledge had made such a deep im-
pression upon the leaders in several depart-
ments of science must certainly have been in
some degree remarkable.
At Mr. Mitchell’s house in Victoria he had
large collections of animals of all classes.
From day to day the house was visited by
ranchmen, doctors, school children and others
to ask about various points connected with
natural history. Thus, technical men as well
as persons from the ordinary walks of life
were alike influenced by the learning of the
man.
Mr. Mitchell lived for a good portion of
his life on a eattle ranch on the coast of
SCIENCE
469 .
Texas. His love of natural history was in-
herited from his mother, who had extensive
knowledge of the plants of Texas and _ their
practical uses. Later he moved to Victoria
where circumstances gave him an opportunity
to devote most of his time to work on nat-
uval history. In 1904 he became connected
with the Bureau of Entomology and made -
important contributions to several of the
larger southern problems like those of the
cotton boll weevil and the eattle tick. In
fact, his pioneer work on the cattle tick was
an important factor in the notable project
of eradication which now permanently
removed the pest from more than three fourths
of its original range in the United States.
Mr. Mitchell had no technical training. He
was an example of the vanishing type of de-
voted naturalists who pursue the subject out
of pure love for nature. He never described
a new species. Although he collaborated on
many publications of the Bureau of Ento-
mology, he published only one paper, dealing
with the poisonous snakes of Texas. Never-
theless, it is fitting that this note about. his
career should be published in this journal.
He was a fountain of accurate information
for technical men and was a modest, patient
and painstaking imparter of knowledge. His
life showed the enjoyment which comes from
the contact with nature and was thus an in-
spiration to others.

ANNUAL TABLES OF CONSTANTS
Tue confederation of French scientific so-
cieties has renewed for the year 1922 its eon-
tribution of 40,000 franes in support of An-
nual Tables. The total subscription in France
to this project during the year 1921 was 80,000
franes.
At the approaching meeting of the Interna-
tional Union of Pure and Applied Chemistry
which is to be held at Lyons in June, the mat-
ter of organizing the work of Annual Tables
upon a solid financial basis will come up for
consideration. This important international
project has had a very precarious existence
470
since 1914 and the fact that the work has been
continued at all has been due to the efforts of
the general secretary, Dr. Charles Marie.
Plans for providing a certain and sufficient
budget for the work during the next five years
are in preparation, based upon definite annual
contributions from the various countries in the
International Union. i
It is announced that the National Research
Council of Japan has appointed the following
advisory committee for Annual Tables: Yasu-
hiko Asahina, Hiji Aoyagi, Kotaro Honda,
Katsuji Inouye, Gen-itsu Kita, Koichi Matsu-
bara, Tsuruzo Matsumura, Seiji Nakamura,
Kyoji Suyehiro, Umetaro Suzuki, Takuro Ta-
maru, Mitsumarn Tsujimoto, Nobuji Yamaga,

mittee is Professor Yukichi Osaka, Japanese
member of the International Commission in
charge of Annual Tables.
ALASKA PENINSULA FISHERIES
RESERVATION
Unner date of February 17, 1922, an Execu-
tive order was promulgated creating the Alaska
Peninsula Fisheries Reservation, extending east-
ward from the Aleutian Islands Reservation to
a line from Foggy Cape, on the eastern end of
Sutwik Island, to Cape Menshikof, on the
northern shore of the Alaska Peninsula, and in-
cluding the Shumagin Islands and the terri-
torial waters adjacent to these lands and also
the lands of the Aleutian Islands Reservation.
The Secretary of Commerce is given power to
make regulations for the proper administration
of the newly created reservation and the waters
covered by the executive order. The text of the
order follows:
EXECUTIVE ORDER
In addition to the islands of the Aleutian Chain,
Alaska, withdrawn and made a preserve and
breeding ground for native birds, for the propa-
gation of reindeer and fur-bearing animals, and
for the encouragement and development of fish-
erties, by the executive order of March. 3, 1913
(No. 1733), as modified by the executive order
of August 11, 1916 (No. 2442), a reservation
comprising the islands, peninsulas, and lands ad-
joining the eastern end of the reservation estab-
lished by the said executive order of March 3,

1918, and extending in an easterly and northerly
direction from Isanotski Strait to a line extending
from low-water mark at Foggy Cape, on the east-
ern end of Sutwik Island, to low-water mark at
Cape Menshikof, on the northern shore of the
Alaska Peninsula, including the Shumagin Islands
and all other islands, peninsulas, or parts thereof
within the described area, is hereby set apart as
a preserve to more effectively insure the protection:
of the fisheries and for their encouragement and
development. This latter reservation is to be
known as the Alaska Peninsula Fisheries Reserva-
tion.
It is hereby further ordered that all straits,
bays, and other waters over which the United
States has jurisdiction by reason of their rela-
tion and proximity to the islands, peninsulas, and
other lands to which this order, as well as the said
order of March 3, 1913, applies, be and the same
are hereby reserved and set apart also as a pre-
serve to more effectively insure the protection of
the fisheries and for their encouragement and
development.
The secretary of commerce shall have power to
make regulations for the proper administration of
the said Alaska Peninsula Fisheries Reservation,
and the straits, bays, and other waters reserved
by this executive order.
The establishment of the reservation under this
executive order shall not interfere with the use of .
the waters, islands, or other lands for lighthouse,
military, naval, or other public purposes, nor with
the use of any of said islands or other lands under
the laws of the United States for town-site pur-
poses, mining purposes, or grazing of animals
thereupon, under rules and regulations to be estab-
lished by the secretary of the interior.

Reservation.
THE FLORA OF PORTO RICO
Dr. N. L. Brrrron, director in chief of the
New York Botanical Garden, has returned from
Porto Rico, after three months spent in an in-
tensive study of the Porto Rican flora.) Dr.
Britton reports a very successful trip and the
May 5, 1922]
collection of some 4,000. specimens. In addi-
tion to collecting plants and specimens for the
garden, the object of the expedition was the ob-
taining of data for a flora of Porto Rico and
the adjacent islands for publication by the New
York Academy of Sciences, as parts of the sci-
entific survey of Porto Rico and the Virgin
Islands.
This survey was commenced in 1913 by the
New York Academy of Sciences in cooperation
with the insular Government of Porto Rico, the
American Museum of Natural History, the New
York Botanical Garden, the department of
geology and of anthropology of Columbia Uni-
versity and with other American institutions.
The work has been prosecuted since whenever
practicable, but was much interrupted by the
World War. In his report to the scientific di-
rectors of the garden, Dr. Britton says of the
accomplishments to date in connection with the
survey:
The materials brought together already have
formed the basis of numerous noteworthy con-
tributions to knowledge, published by learned soci-
eties and by the cooperating institutions. Pub-
lication of the final reports was begun by the
Academy in 1919, and three parts of the geological
volumes and two of paleontology have now been
issued, under the editorship of Professor R. W.
Tower of the American Museum of Natural His-
tory. Additional parts of the geological volumes
are now ready for the press, to be followed by
those dealing with the botany and vegetable re-
sources, the zoology, archeology and anthropology
of the islands, as rapidly as funds for printing
become available. The completion of the work
will make the geology and natural history of
Porto Rico and the Virgin Islands, insular posses-
sions of the United States, the key to natural
science knowledge of the West Indies.
The objects of the trip as detailed by Dr.
Britton on his return were to supplement infor-
mation about the vegetation obtained during
several previous visits to the region and from
the study of many specimens obtained by other
collectors in former years; to ascertain now that
the geological field work in Porto Rico has been
completed, such distribution of species as may
be governed by soils of different mineral com-
position, and to increase the representation of
SCIENCE
471
Porto Rican plants in the collections of the gar-
den, with duplicates for exchange with other
botanical institutions. These objects were sat-
isfactorily accomplished, he says, over consider-
able areas of the island, special attention being
given to the Northern and Southern Coastal
Plains and to the higher mountain summits of
the central districts.
EXPEDITION TO THE FIJI ISLANDS
A British government launch may be placed
at the disposal of a party of scientifie men from
the University of Iowa who will be in the Fiji
Islands on a collecting expedition during June
according to a letter to Professor C. C. Nutting
from Mr. T. E. Fell, acting governor of Fiji.
Professor Nutting is head of the expedition
which will sail from Vancouver on May 19 to
the Fijis and New Zealand to gather laboratory
and museum material for the university. Mem-
bers of the party are: Professor R. B. Wylie,
head of the department of botany; Professor
A. O. Thomas, geologist; Professor Dayton
Stoner, entomologist and ornithologist; Mrs.
Dayton Stoner, who will assist in entomology;
Waldo §. Glock, photographer and assistant
geologist; and Professor C. C. Nutting, director
of the expedition, whose specialty is marine
invertebrates.
Arriving at Suva, Fiji Islands, about June 3,
the party will be personally greeted by Governor
Fell, who, as acting governor of Barbados at
the time of the university’s Barbados-Antigua
expedition in 1918, extended many courtesies to
the members of that party, which was also in
charge of Professor Nutting.
The entire island of Makaluva, near Suva,
has been placed at the disposal of the visitors,
and the necessary buildings and equipment are
conveniently at hand there. In addition to the
launch the governor expresses his hope of hay-
ing a small boat at hand for use in exploring
the neighboring reefs, and arrangements are be-
ing made in advance for divers and reef experts
to aid the party. All scientific equipment is
to be admitted free of duty.
After remaining at Suva until early in July
to make a study of Marine and tropical life, the
472
party will go to New Zealand, where animal
and plant life and geological formations are
of peculiar interest. The official secretary of
New Zealand has written to say that everything
possible will be done to make their stay in that
country a success. It is expected that the re-
turn voyage will end in Vancouver about Sep-
tember 9 in time for the opening of the uni-
versity.
THE SECTION OF. MEDICAL SCIENCES OF
THE AMERICAN ASSOCIATION
Ir may be of some interest, in this period of
co-ordination, to know that at the Toronto meet-
ing a group of parasitologists, medical entomol-
ogists and medical workers met and decided
upon the following policy for Section N, Medi-
eal Sciences :
1. That it was extremely desirable and nec-
essary that a closer co-ordination between para-
sitologists, entomologists and medical workers
be worked out.
2. That the secretary of Section N (Medical
Science), after consulation with the secretaries
of the related societies, arrange for a program
which will avoid conflicts with related groups.
3. That the secretaries of the allied societies,
co-operating with the secretary of Section N
(Medical Sciences), suggest those of its mem-
bers who might be invited to take part in a
symposium at which the significant researches
are reported that are of interest to the alhed
groups of workers.
4. It was deemed undesirable to attempt for
the present any formal co-operation between
these related societies.
5. That the time has come when there is a
definite need for the discussion of such papers
as affect the interests in the allied groups, both
for stimulation and for information.
6. That each secretary so arrange the papers
of its society’s program that it may be possible
for its members to meet with Section N (Medi-
cal Sciences) without too serious a loss.
7. That the joint meeting be held under the
auspices of Section N (Medical Sciences).
Section N (Medical Sciences) is proceeding

THE BOCHER MEMORIAL PRIZE OF THE
AMERICAN MATHEMATICAL SOCIETY
THE American Mathematical Society an-
nounces the foundation of a prize in memory of
the late Professor Maxime Bocher, of Harvard
University. Soon after the death of Professor
Bocher, in 1918, a fund was raised in his mem-
ory through the efforts of Professor T. S. Fiske,
of Columbia University, which was turned over
to the American Mathematical Society. On
recommendation of a committee of which Pro-
fessor E. B. Van Vleck, of the University of
Wisconsin, was chairman, the council of the so-
ciety has decided to devote the interest of this
fund to the establishment of a prize, to be called
the Bocher Memorial Prize, and to be awarded
at five year intervals, for a notable research
memoir published in the Transactions of the
American Mathematical Society during the pre-
ceding five years by a resident of the United
States or Canada. The age of the recipient
shall not be over forty years, and the prize shall
not be awarded twice to the same person. The
first award (of $100) is to be made for a
memoir published during the period 1918-1922,
and will be conferred at some meeting of the
society in 1923.
This prize, which is believed to be the first
mathematical prize to be given in this country
at regular intervals for research in pure mathe-
matics, is an especially appropriate memorial
for Professor Bécher, not only because of his
achievements in research, but also because of
his great services to mathematics in this country
as one of the founders and for many years one
of the editors of the Transactions of the Ameri-
can Mathematical Society; for this latter reason
the provision that the prize must be awarded
for a memoir published in the Transactions
seems particularly appropriate.

A CONFERENCE of those who teach physiology
in the women’s colleges of the northeast was
held at Mount Holyoke College on April 21 and
22. The conference had to do almost entirely
with teaching problems, since there have been
very few opportunities for such discussions at
the usual scientific meetings. Among the topics
were the aims of the courses given at the various
institutions, the prerequisites and content of
the courses, the choice of material for experi-
mental purposes, the affiliations of physiology
with chemistry, physics, zoology and hygiene,
and the type of research possible with undeyr-
graduates. The institutions represented were
Barnard, Bryn Mawr, Connecticut, Goucher,
Mount Holyoke, Simmons, Smith, Vassar and
Wellesley.
Wittiam Woop & Co. have transferred pub-

operated for four years as an experimental and
demonstrational plant with a view to the devel-
opment of processes for extracting potash and
by-products from the giant kelps of the Pacific.
It was closed through Congressional action in
1921. The plant will be enlarged and put back
into operation at once for the manufacture of
“Kelpchar” (a decolorizing carbon of very high
activity), potash salts, and iodine. Dr. J. W.
Turrentine, who was in charge of the plant
throughout the period of the experimentation,
after turning over to the Government’s succes-

Oregon and Washington. He will first proceed
to the Kasaan National Monument, Alaska, to
study the architecture, totem poles and other
objects at this village and will be accompanied
by a half-breed Haida, related by marriage to
Chief Skoul. It is expected that considerable
legendary data bearing on history and sociology
of the former inhabitants of Kasaan will also be
collected. Should the results justify further
work it is planned to continue field-work on
place names and aboriginal village sites of
Alaska to be followed later by work on strati-
graphic archeology in more northern latitudes in
order to discover if possible traces of the oldest
Indians in this supposed prehistoric gateway of
the migration of man into North America.
AccorDING to the correspondent of the Asso-

THE ninth annual Faculty Research Lecture
at the University of California by election by
the Academie Senate was given by Dr. Charles
A. Kofoid, professor of zoology in the univer-
sity who spoke on Charter Day, March 22, on
“Amceba and man.” The discovery was an-
nounced of the detection of amceba in the bone
marrow in eases of Ely’s second type of
arthritis deformans in man. The amebic na-
ture of the parasites in the bone lesions was
demonstrated by their mode of cell division
and the number of chromosomes which differ
from those of human cells.
THE correspondent of the London Times at

the solemn reception of Mme. Curie by the
Academy of Medicine is a fait accompli. The
secretary-general read the terms of the decree
by which the president of the republic ap-
proved the election of Mme. Curie. As an un-
precedented mark of honor, M. Béhal made a
speech to welcome the first Académicienne. He
reminded her that it was about twenty years
ago that, in response to his request, she gave
a lecture at the Sorbonne on radium, which she
May 5, 1922]
had discovered, and was studying with her hus-
band, Pierre Curie. He rapidly reviewed the
ground traveled since then, and continued:
“All these discoveries which result from yours
are as nothing compared with the fundamental
fact which you found—I mean the formidable
energy contained in the atomic system. If we
are to succeed in being able to release it
methodically it would relieve the world from
the dread of seeing disappear, at short notice,
reckoning time in relation to the age of the
world, the fuel accumulated in former centuries
which is at present our principal source of
energy.” Mme. Curie bowed low and took her
seat simply and without a word among her
eminent colleagues.
Dr. Lynps Jones, from the department of
animal ecology of Oberlin College, is arranging
a special field expedition to leave Oberlin on
June 23, going west through Illinois, across
the Mississippi to Iowa and on toward Mac-

Big Horn Mountains in Wyoming into Yellow-
stone Park. The itinerary will then take the
party to Poeatelo, Idaho, on to Salt Lake City
and southern Utah, visiting the National Moun-
tains and Bryce’s Canyon. Leaving Utah, the
group will strike across the northern part of
Arizona and the southern tip of Nevada into
southern California. Proceeding to the coast a
week’s camp will be made near San Diego.
Sixteen students will make up the party, trav-
eling with automobiles with complete camping
outfit. Special attention will be given to the
study of bird and animal life and field maps
and topographical surveys will be prepared
covering all parts of the route.
Tue Department of Commerce will send a
party, headed by Assistant Secretary C. H.

of making a general investigation of conditions
in which that department is particularly inter-
ested. The Bureau of Fisheries, the Coast and
Geodetic Survey, the Lighthouse Service and
the Steamboat Inspection Service are the
bureaus of the department which are closely
identified with the affairs of the territory. It
is the purpose to determine in what ways these
bureaus can be made of greater benefit in devel-
SCIENCE 417
oping Alaska. Particular attention will be de-
voted to the salmon fisheries, which yield
produets of an average annual value of about
$40,000,000 and in normal seasons give employ-
ment to upwards of 20,000 persons and repre-
sent an investment of about $70,000,000. It
will be the purpose also to observe conditions
in respect to the fur-seal industry at the
Pribilof Islands, which work is administered
by the Department of Commerce through the
Bureau of Fisheries.

DISCUSSION AND CORRESPOND-
ENCE
THE FUTILITY OF THE HUMAN YOLK SAC
In the current issue of the Anatomical
Record, Professor Arey publishes a brief but
very interesting contribution (No. 90) from the
Anatomical Laboratory of Northwestern Uni-
versity. He describes a human chorion con-
taining two embryos, of 11.5 and 12 mm.
respectively, one of which has a yolk sac, and
the other has none—that is, none was found,
and sections of the umbilical cord showed no
trace of a yolk stalk. Hence the broad con-
clusion is drawn that “the human yolk sac is a
vestige unessential to growth or differentia-
tion (ineluding vasculogenesis).” It is stated
that one of these embryos “received all, or
essentially all, the cells destined to form a
yolk sae” and that “the total absence of a
yolk sae in one embryo, which is otherwise
normal in every way, further demonstrates
conclusively that this organ is not essential to
the growth of an embryo or to the proper dif-
ferentiation of its parts; indeed, the embryo
in question is slightly larger than its twin.”
Since from the days of Wolff the yolk sac
has been regarded as the source of the intes-
tinal tract, and in young human embryos is
seen to be the organ from which the allantoic
duct and the digestive tube proceed, the
startling nature of this conclusion becomes
apparent. But it is universally recognized
SCIENCE
[Vou. LV, No. 1427
that the yolk sac does its work in early stages,
and though the sae usually persists as a fune-
tionless rudiment until birth, its duet normally
becomes parted through atrophy in embryos
younger than the one under consideration.
Does Dr. Arey’s case indicate anything more
than the precocious obliteration of the stalk of
an organ no less essential than the placenta,
likewise cast off after its very vital functions
have been performed? ;
Tf the question is raised, Where then is the
yolk sae in Dr. Arey’s case? his own studies
furnish a plausible answer, since in another
specimen he has deseribed a single sac with
two stalks, each leading to a separate embryo.
Under such cireumstances, the early oblitera-
tion of one of the stalks would give rise to the
conditions observed in the second case, and
this possibility must be eliminated before ac-
cepting the proposed conclusion. In reading
the account of a human embryo without a yolk
sae, we recall Bentham’s incredulous comment,
“T am very glad, my dear sir, that you saw
that, for had I seen it myself, I wouldn’t have
believed it.”

DEFLECTION OF STREAMS BY EARTH
ROTATION
THE recent note by Professor Jennings sug-
gesting that the steeper valley sides on the
right of the south-flowing streams on Long
Island may be due in some manner to wind
action instead of to the deflective effect of the
earth’s rotation is a welcome contribution to
an old problem. In spite of Gilbert’s apparent
acceptance of the earth’s rotation in explana-
tion of the unsymmetrical cross-section of those
valleys, the small size of their streams has
always stood in the way of it, all the more
since Bowman showed, on the basis of accurate
maps of the lower Mississippi, that even that
great river shifted its course to the east or left,
apparently under the control of the wind, and
not to the west or right, as it should if the
earth’s rotation were in control.t

It is, however, interesting to note that the
remarkably well defined right-handed or east-
ward shifting of many radial streams that flow
down the gentle slope of the great alluvial fan,
known as the plateau of Lannemezan, at the
northern base of the Pyrenees—hbeautifully
shown on the 1:80,000 map of France, sheets
216, 217, 227, 228, 229, 239, 240, and 241—
has been explained by Marchand and Fabre?
not as a consequence of the earth’s rotation but
as a result of stronger action of rain driven
by westerly winds; so that here it is the valley
sides facing against the wind that are the
steeper, while on Long Island the steeper val-
ley sides face with the winds. It is difficult to
understand just how either explanation works,
but in any case the relation of the steep valley
sides and the prevailing winds is unlike in the
two examples.

POSSIBLE CAUSE OF THE RED COLOR OF
POTASH SALTS
THE red color of certain potash and ordinary
salt deposits has been observed in many parts
of the world, for example, in the Indian, Ger-
man, Alsatian and Spanish potash deposits, in
Nova Scotia, west Texas and doubtless in other
places that the writer has not heard of. The
same, though a less intense coloration has been
observed by the writer in the surface salt and
strong brine standing in the trenches and in
pools along the margin of the salt ponds where
solar salt is made along the shore of San Fran-
cisco Bay, California. It has been noted at
Searles Lake in the same state. I am told that
the same red color exists also in the solar salt
ponds on Turks Island. It is undoubtedly of
common occurrence in many places where solar
evaporation results in producing salt, either
naturally or artificially.
The red color associated with certain potash
minerals is so common that it has come almost
to be regarded as a means of identifying cer-

les plateaux des Hautes Pyrénées. OC. R. Congr.

SCIENCE
479
tain of them, for example, the mineral carnal-
lite in the German deposits. There is however,
as chemists well know, nothing inherent in the
composition of carnallite (KC1.MgCl,.6H,0)
to cause this red tint and indeed the normal
color of the pure double salt should be the same
as that of ordinary white rock salt.
There has been a great diversity of opinion
as to the origin of the red color in solar salt
and bitterns where solar evaporation is in pro-
eress. That it is not necessarily due to the
presence of iron appears evident from the ob-
servations of George Lunge, the expert on sul-
phurie acid manufacture. Lunge' states that:
The red. color exhibited by many alkaline
salt lakes, which is often also apparent in the
salt deposits, is ascribed by Payen? to the pres-
ence of small crustaceans, Artemia Salina Leach
(Cancer salinus Linné), which appear in large
masses when the water has attained a density of
1.16, and which are of a gray or greenish color;
on further concentration to a specific gravity of
1.21, they die and form a red froth at the sur-
face. ... I, for my part, must decline to accept
the assumption that the red color is regularly
caused by the presence of Artemia or other ani-
mal organisms, if it is ever due to that cause;
for the samples of red water which I had myself
taken from the lakes of the Wade Atrun have
preserved that color during the many years I have
kept those samples. The red filtrate shows noth-
ing under the miscroscope; the color is at once
discharged by adding nitric acid or hypochloride
and hydrochloric acid and is evidently caused by
organic substances present in solution. There is
no iron present.
Recent studies made in the U. S. Bureau of
Fisheries, Department of Commerce, connected
with the reddening of salt fish are of interest
and importance in this connection. They are
also of economic value in view of the consider-
able annual losses to the fish industry caused
by salt fish developing a red color when stored
under moist conditions. The Bureau investiga-
tions, which were conducted by W. W. Browne’,
i Lunge, Geo., Sulphuric Acid and Alkali, Vol.
2, pt. 1, p. 58, 1909.

indicate that the red color is due to two micro-
organisms, which probably originated in the
sea salt used in euring the fish. The color
varies from pale pink to deep crimson, the
former the result of the growth of a spirochete,
and the latter produced by a bacillus form.
These microorganisms grow in completely
saturated brine on salt fish and on salt piles,
but no growth appears in media containing
less than 15 per cent. of salt by weight. The
most favorable temperature for the growth of
both organisms is between 50° and 60° C. in-
dicating that the salt lagoons of the tropies
are probably sources of infection. Sunlight
is not germicidal, which also points to their
tropical origin where pigmentation is required
against bright sunlight. Ordinary bacteria are
killed by ten minutes exposure to the bright.
sunshine. Salt acts as a preservative prevent-
ing the growth of most organisms, but here is
an instance of just the opposite effect.
In summary, the results of recent investiga-
tion indicate that the cause of the red color in
solar salt and brine is due to organisms as in-
dicated above and that their source is salt pro-
duced by solar evaporation. Both European
and American sea salt is infected, but mined
salt is free from their presence.
The studies made by the Bureau of Fish-
eries and by others before it (See Bibliography
published by Bureau of Fisheries) have sug-
gested to the writer that possibly causes allied
to those now producing red coloration in solar
salts may have been active as long ago as the
Permian. Whatever may be the main cause
of the reddening of the Permian potash salts,
the question naturally arises, is the reddening
in the potash salts of the German Permian, the
Alsatian Oligocene and the Spanish Tertiary
deposits due to the same or similar agencies
that are causing reddening in the solar salt
of the present time. It is probable that both
types of salts have been formed under essen-
tially similar conditions, that is, salt pan con-
ditions. If this last statement be admitted,
then it points to the growth of bacteria, at
least intermittently, from the Permian down to
the present.
This is presented to induce further study

along this line and to elicit discussion and
opinions. Such studies may also throw some
light on temperatures during Permian and
later geologic time.

POPULAR SCIENCE
To tHE Epitor oF ScieNcE: I am sorry to
see that Dr. E. Dorsey confirms! the opinion
expressed by Dr. Brooks? and myself* that sci-
ence is relatively losing ground in popular
interest and esteem. I fear he is right also in
saying that this is in part the fault of scien-
tists. For the prevalent indifference and even
hostility of the public to the higher teachings
of science may be matched by the indifference
and even hostility of certain scientific men to
the “vulgarisation of science.”
It is quite true, as Dr. Dorsey points out,
that isolated facts, however numerous and
authentic, do not constitute science. I have
kept that point in mind in all our Science
Service work. For instance I said in a recent
magazine article :*
We can get from the reading of science not
only new things to think about, but, what is more
important, new ways of thinking about things.
But I hope that Dr. Dorsey will not dis-
courage those of us who are trying to get a
larger amount of “mere information” in the
newspapers. A few more facts are really
needed to season the mass of fiction there. We
may also hope to get over some idea of the
relations between facts and how the scientist
finds his facts and what he gets out of them.
But we ean not expect that the newspaper
reader will acquire the habit of persistent ex-
perimentation, constant criticism, rigorous rea-
soning, projection of hypotheses, balancing of
theories and suspension of judgment character-
istic of the scientific mind. . If the layman

could get all this he would be not a layman but
a scientist. The most we can expect is that the
layman may gain sufficient acquaintance with
scientific thinking to understand the methods
and aims of research and to appreciate its value
to civilization. That he does not commonly
acquire such comprehension and appreciation is
because the men who understand the value of
science have been too often unwilling to take
the pains to impart their information and
inspiration to. him.
We are told that Agassiz required of his stu-
dents in every department to prepare “first a
monograph, second a scientific lecture, third a
popular lecture, fourth a simple child’s tale.”
How many of our annual army of Ph.D.’s
would pass the third and fourth of these intelli-
gence tests? Agassiz had his reward in the
dozens of devoted disciples who became the
teachers of the next generation and in the
thousands of young people who bear his badge
as they search forest and strand with curious
eyes. But we need more men of the Agassiz
type—and we seem to be getting fewer.
England, as I showed in ScrencE, seems to
have more men of high standing who are will-
ing and able to translate their learning into the
vernacular. It would be hard to match in all
America the popular lecturers of the Royal
Institution from Faraday to Bragg. But even
in England we hear complaints of the growing
gulf between the specialist and the public. The
once-popular lectures to workingmen are now
said to be running short of both speakers and
hearers. Last year the columns of Nature
were filled for months with diseussions of why
the lay membership of the British Association
for the Advancement of Science was falling
off. The British Association has always had
the advantage of ours in the large number of
citizens, not professionally engaged in scien-
tific pursuits, who would support and attend
the annual meetings but now it is becoming,
like the American Association, a congeries of
highly specialized sections.
Several of the correspondents in Nature ex-
pressed the opinion that the public had lost
interest and confidence in science because scien-
tists have lost their fighting spirit and the
courage of their convictions. They take every-
thing lying down nowadays and do not dare to
SCIENCE
481
defend their views or even defend their right
to hold and teach their views.
This is a point worthy of consideration by
those American men of science who have
adopted the policy of treating with dignified
contempt the present legislative and ecclesias-
tical attacks upon their intellectual freedom.
Little is being done in scientific circles to check
the rising tide of superstition and intolerance
now sweeping over the land. Perhaps when
appropriations are eut off, as in South Caro-
lina, on the ground that the university has an
evolutionist on the premises our scientific
pacifists may sharpen up their pens and turn
out literature as interesting to the general
reader as Huxley’s debate with Gladstone about
the demons who converted the pigs of Gadara
into pickled pork.
Dr. Dorsey is wise in putting “accounts of
discoveries” first in his list of popular science
subjects. But who will write them? I have
been hunting in vain for writers who could
sense the dramatic elements in such a scene as
Archimedes’ bath and tell how this ancient graft
case led to the law of specific gravity. Who
will describe the feelings of Faraday when he
saw the loose end of a little magnet rotating
about an electric wire in the dingy laboratory
of the Royal Institution and then explain what
that had to do with the trolley cars that are
passing in the street?
The history of science is as rich a field for
the cultivation of good literature as the history
of literature, art and music but it remains un-
tilled for want of attention. Students have
been trained to look another way. The aim is
now to eliminate the personal element from
science and reduce it to an abstract and time-
less formula. This may be necessary as a S¢i-
entific method but it naturally results in the
decline of interest. The old textbooks are
more readable than the modern. A distin-
guished physicist, in discussing this point with
me, said: “When I was in college I had to
study Hastings and Beach but I read Deschanel
for my own amusement.” I am not advising
that our textbooks should return to the
leisurely literary style of long ago but we can
not expect depersonalized science to be popular.
Whatever is without “human interest” is not
interesting to humanity. Dehydrated potatoes

are convenient for conveyance but they have to
be soaked up before they are palatable.

SCIENTIFIC BOOKS
An Introduction to Cytology. By Lester W.
Suarp. McGraw-Hill Book Company, New
York, 1921. 452 pages, 159 illustrations.
For a subject of such wide interest and
great significance as cytology, there are sur-
prisingly few text books. For years Wilson’s
classic work, “The Cell in Development and
Inheritance,’ has been the chief reference vol-
ume, especially of the beginning investigator.
Very recently two English texts, one by W. E.
Agar, “Cytology, with Special Reference to the
Metazoan Nucleus,’ and another by L. Don-
easter, “An Introduction to the Study of
Cytology,” have appeared. These are good
books, dealing in both cases, however, with a
rather limited field and largely with animal ma-
terial. There has long been felt the need for an
introductory text which would present an out-
line of the subject in both its botanical and
zoological aspects. The rapid advances made
by numerous investigators, working upon a
great variety of materials, and the intimate
relation of these in many cases to equally rapid
developments in the other new science of
genetics, have made the writing of a cytological
text book a very difficult matter.
Professor Sharp, despite these obstacles, has
done an excellent piece of work for he not only
covers the fields of botany and zoology, but
embraces in his consideration of subjects most
of those necessary for an understanding of the
scope of cytological knowledge. Very properly,
however, he places emphasis upon the topics of
greatest general interest. We find, therefore,
that of the 452 pages of text, 240 are devoted
to the hereditary mechanism and the results of
its operation. Zoologists, particularly, will
welcome so comprehensive a summary of the
achievements of their botanical fellows as Pro-
fessor Sharp presents. While this is naturally
the strong part of the work, zoological material
is well considered. Indeed, the author deserves
special commendation for the completeness and
fairness with which the contributions of zoolo-
SCIENCE
[Vou. LV, No. 1427
gists are treated. In view of the general ex-
cellence of the book in this respect, it might be
permitted, in the interest of the accuracy for
which the author very evidently strives, to
point out that in a few cases he has allowed
his personal studies to influence his presenta-
tion of topics concerning which there are dif-
ferences of opinion. Perhaps the most con-
spicuous example of this is in the discussion
of the differential structure of the chromatin
thread. While there may be uncertainty on
this point in plant material, there is none in
many animal forms.
The method by which the material is pre-
sented is entirely to be commended. In recog-
nition of the developmental stage of the sub-
ject, Professor Sharp has endeavored to set
forth its status by showing what the problems
are and how they are being met, rather than
by attempting to define in categorical terms
the content of our knowledge. The spirit and
motives of an investigation are as important as
its achievement, and, since cytology is now so
largely a matter of discovery, it would be a
misrepresentation to exhibit it otherwise than
as an active field of research.
As practical measures for such a presenta-
tion it may be noted that the numerous illus-
trations are, almost always, copies of those
found in research papers instead of those from
text books; extensive bibliographies follow
each chapter, offering the means for a compre-
hension of the extent of the work done and for
following up any particular subject;! there is
a full index in which may be found the tax-
onomic position of all materials discussed;
scattered through the chapters are brief his-
torical or critical reviews of nomenclature;
there are frequent diagrammatic figures which
1 As indicating the scope and character of these
references it may be noted that at the end of
Chapter XI, ‘‘The Reduction of the Chromo-
somes,’’ a total of 170 individuals, of 11 nation-
alities, are quoted. The distribution of these
biologists is interesting, indicating, as it does in
a general way, the interest in cytology exhibited
in different countries. Of the 170 individuals
referred to, there are 54 Americans, 46 Germans,
26 British, 13 French, 9 Japanese, 7 Scandina-
vians, 6 Belgians, 4 Hollanders, 2 Russians, 2
Italians, and 1 Pole.

present concisely the essential steps in the
processes under consideration. These, with
other features, make the book very accessible
and helpful. It might here be suggested that
the diagrams would be improved by larger
index characters, and that somewhere a concise
index to the various terminologies scattered
through the chapters would make them more
available.
It is not to be hoped that in a book of this
character there should be an absence of errors,
although in this imstance they are not so
numerous as usual. Certainly they do not
render the text as a whole unsafe for the un-
guided beginner. Because of the merit of the
book in general and its obvious adaptability to
the present needs of a great variety of people,
it is particularly important to reduce errors of
all sorts to a minimum. Undoubtedly, the cor-
dial invitation of the author for assistance in
eliminating these will be met with a helpful
response by his fellow workers. Here it should
suffice to speak of only more general features
needing attention.
Owing to the fact that the book will most
largely be used by those generally unfamiliar
with cytology, and having varied approaches
to it, there is need for the greatest clearness in
distinguishing between the different categories
of objects and conditions described. This is
not. always done and there is sometimes con-
fusion between gene and character, and be-
tween the valence of the elements in the
chromosome complex. In the effort to simplify
the presentation of the maturation phenomena
in some of the diagrams, only one mitosis is
shown. While this displays clearly one of the
important conditions of meiosis it entirely
neglects another, viz., the essential unity of the
two maturation mitoses as a process. This is
further emphasized by the consistent use of the
terms “heterotypic” and “homotypic.” Enough
evidence has been presented to show beyond
question that the first maturation mitosis is not
necessarily a reduction division as the terms
imply. It is necessary only to recall the be-
havior of the sex chromosomes in the Hemip-
tera and the “selected chromosomes” in Phry-
notittix, as described by Wenrich, to demon-
strate this. There is something in meiosis be-
sides a reduction division and an ordinary
SCIENCE
483
equation division. It is important to show
clearly that meiosis is a unique phenomenon.
Doubtless, there are other instances of sim-
ilar differences in point of view between
author and reviewer which might be used to
illustrate the present status of opinion in
cytology, and the degree of adaptability of the
text of Professor Sharp as an introduction to
the subject. What has been given will, how-
ever, suffice to show that the existing differences
of opinion are not extreme, that they are fairly
presented in the text, and that in their exposi-
tion, a work has been produced that will serve
to extend the usefulness and influence of
cytology greatly. It is not venturing far to
predict that the “Introduction to Cytology”
will take its place as a worthy member of the
very successful series of which it is a part.

CONTINUOUS RENEWAL OF NUTRIENT
SOLUTION FOR PLANTS IN WATER-
CULTURES
In the experimental study of the salt nutri-
tion of plants, it is of course very important
that all the influential features of the culture
media be definitely known. The initial com-
position of a mixed salt solution employed for
water-cultures may be known with a marked
degree of accuracy, but the chemical make-up
of such a nutrient solution begins to be altered
immediately after the introduction of the
plants; materials, of course, move from the
roots into the solution, as well as in the oppo-
site direction, and the solution soon becomes
significantly different from what it originally
was. Since there is no feasible way by which
all the various kinds and rates of alteration
may be adequately determined, the culture
solutions must be renewed from time to time if
the growth of the plants is to be correlated
with known chemical conditions surrounding
their roots, and renewal must be frequent
enough to allow these unknown alterations to
be regarded as uninfluential.
How frequently water-culture solutions
should be renewed is always a difficult ques-
tion. With small culture vessels, with large
plants, or with many plants in a vessel, it is
484
clear that renewal ought to be more frequent
than with larger vessels, smaller plants, and
so forth. The labor involved is generally a
serious consideration also. Whether solutions
were renewed frequently enough, in particular
experiments, to allow growth to be correlated
with the characteristics of the solutions as
these were originally prepared has been a sub-
ject of discussion from time to time. To an-
swer this question for any experiment, a num-
ber of different renewal frequencies may be
simultaneously tested, to determine how often
the solutions must be changed in order that no
difference in growth may result with still more
frequent renewal.
A consideration of this question, together
with the amount of labor involved in renewing
a large series of solutions, leads obviously to
the suggestion that the solution might be made
to flow continuously through the culture vessel,
the inflow being of known composition and the
outflow being discarded. If the rate of flow is
rapid enough, the discarded solution will not be
significantly different from the inflow, and the
roots may be said to have been in a known set
of chemical surroundings throughout the cul-
ture period. Several rates of flow should be
simultaneously tested, at least in a preliminary
way, in order to make sure that the data
studied shall have been secured with a suffi-
ciently rapid rate. By employing continuous
flow, the labor of renewing solutions would be
practically avoided, since the apparatus would
operate continuously without alteration, aside
from the preparation of solutions and their
introduction into the apparatus from time to
time. The apparatus should automatically
maintain any desired rate of flow through the
culture vessel. \
The need of an apparatus for continuous
flow has become increasingly evident through-
out the recent development (begun by Schrei-
ner and Skinner, and Tottingham) of water-
culture experimentation by means of logically
complete series of salt combinations. A pre-
liminary step was taken when Trelease and
Free,! working in this laboratory in 1916, con-
1 Trelease, 8. F., and E. E. Free: ‘‘The effect
of the renewal of the culture solutions on the

cluded that Shive’s nutrient solution R5C2
(1.75 atm.) gave better growth the more fre-
quently the solution was renewed, a continuous
flow giving better growth than did daily re-
newal. Although, with the gradually improv-
ing technique of the water-culture method,
many workers? have doubtless appreciated the
desirability of continuous flow, constantly
flowing solutions appear not to have been sub-
jected to any further tests thus far recorded
in the literature? It is interesting to note,
however, that the logical need of continuously
renewed culture solutions was clearly stated by
Stiles.t when he wrote: “In no case has a con-
stantly renewed culture solution been employed.
Thus the ratio of the various constituents was
probably constantly changing throughout the
experiments, and instead of being a constant
factor was an unknown and varying one.”
Also, Duggar® mentioned the need of fre-
quently renewed or continuously flowing solu-
tions, but coneluded that any operation involv-
ing continuous flow “would be impracticable
in most of our experimental work.”
This paper is planned to emphasize still fur-
ther the need of flowing solutions and to pre-
sent a brief description of an arrangement for
securing them.

essentially of four parts: the upper reservoir
(R), the constant-level tank (L), the lower
reservoir (QO), and the culture vessel (V). The
upper reservoir (R) holds 5 gallons of solu-
tion when full, and acts like a constant-pressure
aspirator, drawing air through tube A’A and
delivering solution through the siphon tube
(B), to the constant-level tank (L). The latter
is a piece of 5-em. glass tubing closed below by
means of a rubber stopper with three tubes,
B, E, and D. Solution flows into the tank
through tube B, at a rate somewhat greater
than is required for the culture vessel, and
the excess passes into the lower reservoir (O),
through the tube E, the tank level being auto-
matically maintained at the top of the last-
mentioned tube. The rate of flow through B is
adjusted by adjusting the height of the lower
end of tube A with reference to the upper end
of E. Solution flows at a practically constant
rate from the constant-level tank, through a
small-bore delivery tube (D), and drips regu-
larly into the thistle-tube receiver (F') of the
culture vessel. The desired rate of flow
through tube D is secured by adjusting the
height of the upper end of E with reference to
leet: ; SCIENCE
485
the lower end of D—that is, by adjusting the
“head” maintained by the constant-level device.
The culture vessel shown is a 3-gallon, glazed
earthenware “butter” jar, covered by a paraf-
fined top, of wood, cement or plaster of Paris,
with eight large openings, in which are set
the flat cork stoppers that support the plants.
There are five wheat seedlings in each stopper,
forty seedlings in all. The top is supported
about 4 mm. above the top of the jar. The re-
ceiver tube (F) has a waxed-paper cover,
through which passes the delivery tube. Tube
F extends nearly to the bottom of the culture
vessel, and solution flows into the latter, keep-
ing it filled to the brim and overflowing at the
top, through the waste tube (G).
Solution that collects in the lower reservoir
(O) has not been vitiated in any way by its
passage through the constant-level tank, and
it is raised to the upper reservoir (R) from
time to time, together with additions of newly
prepared solution. This transfer is effected
through the tube A”A, by closimg cocks A’
and B’ and applying suction at C (by means
of an ordinary filter pump). When the trans-
fer is completed, cock C is closed and cocks
A’ and B’ are opened.
The reservoirs should be covered with opaque
paper, to exclude nearly all light and retard
the development of alge.
The constant level device and the lower reser-
voir may be dispensed with entirely if the tem-
perature of the upper reservoir can be main-
tained practically constant, or if only an ap-’
proximately constant rate of delivery of solu-
tion is desired. In this case, tube B would
discharge directly into the receiver tube (F).
This simpler apparatus is the one employed
by Trelease and Free.
Doubtless, the apparatus here described may
be modified in many ways, to suit the facilities
and requirements of different experimenters;
but this form operates very satisfactorily. As
thus far used, a series of five are delivering
five different solutions to their respective cul-
ture vessels at a rate of about 16 liters a day,
which amounts to 400 ee. a day for each of
the forty plants in the culture. With liter
jars, five plants per culture, and solution re-
newal every three and one half days (as in
the plan published by the National Research
486
Council Committee on Salt Requirements of
Plants) each plant would receive 57 ¢.c. per
day.

NOTE ON THE SYNTHESIS OF ETHYL
BUTYRATE IN EGG SECRETION
In our analyses of egg secretion, Miss Wood-
ward: and I? have isolated an enzyme of the
lipase group. The material, precipitated as a
white powder, is soluble in both sea-water and
fresh. In the presence of this “lipolysin,”
droplets of egg fat decrease in diameter while
the hydrolysis of other neutral fats and the
cleavage of ethyl butyrate are measurably ac-
celerated.®
Since lipolysin is a parthenogenetic agent; *
since the unmodified egg-secretions also have
parthenogenetie® and lipolytic? powers; and
finally, since eggs with secretions removed by
brief exposure to charcoal are completely
sterile? it seems likely that lipolysis plays
some réle in the normal initiation of develop-
ment.! However, the evidence that egg-secre-
tions have these powers is still incomplete. It
has not been reported whether, under condi-
tions significant for fertilization theory, the
effects already observed are reversible.
Accordingly, I prepared egg-seeretion as
free from contamination as possible and used
ehloroform to inhibit bacterial action. To 10
or 15 «ce. of this, I then added, in one set of
experiments, .5 c.c. of absolute ethyl alcohol;
in another, 5 ¢.c. of 2N. Butyrie acid was intro-
duced last of all. The final concentration of
the acid was roughly .25 N. and .4 N.
The acidity of the systems was, of course,
immediately reduced by the salts present in
both the secretion and the sea-water. Under
the cireumstances then, the loss in total acidity
has no meaning for the problem in hand. Only

differences are important, and, if in the pres-
ence of egg-secretion, a portion of the butyric
acid is transformed into butyric ester, the tubes
in which this oceurs should require less alkali
than the controls in order to reach the turning
point, Px., of di-brom-thymol-sulpho-phthalein.
The differences of acidity actually found be-
tween 10 c.c. of control and 10 ce. of digest, -
in one case, after 40 minutes at 20° C., amount-
ed to .8 ¢.c. NaOH N/20; in another, after an
hour, to 2.4 ¢.c. NaOH N/20, in both instances,
in favor of the controls.
Absolutely, these discrepancies are small, but
even greater differences might fail to be con-
vineing, for conceivably, the organic constitu-
ents of the secretion, still largely unknown,
might in some way destroy or otherwise remove
butyric acid from the reaction system. For-
tunately, however, ethyl butyrate has an odor
so penetrating and characteristic that even
minute traces can be unmistakably detected.
By this delicate test, the ester, regularly absent
from the controls, was present in noticeable
quantities in the digests with secretion and was
easily recognized by others not familiar with
the experiments. For eighteen hours the ester
smell continued to grow in intensity.
On the basis of these results, I attribute to
ege-exudate the power to accelerate the syn-
thesis of ethyl butyrate. This is neither more
nor less than might be expected since the same
exudate also -accelerates the corresponding
hydrolysis.

At the annual meeting of the National Acad-

papers were presented as follows:
The new building of the National Academy and
the National Research Council: C. D. Waucort,
President of the Academy. The erection of a
magnificent building, costing $1,300,000, as the
home of the National Academy of Sciences and
the National Research Council, will shortly be
begun on the square bounded by B and C streets,
21st and 22d streets, northwest, Washington. The
May 5, 1922]
building will serve as a center for American sci-
ence in its various fields. Here investigators from
all parts of the country and from abroad may be
brought togther for counsel and cooperation.
Facing the Lincoln Memorial, the marble building
in simple classical style will rise three stories
from a broad terrace. It has a frontage of 260
feet. On the first floor there will be an audito-
rium seating some 600 people, a lecture hall hold-
ing 250, a reading room, library, conference
rooms and exhibition halls. The basement con-
contains a cafeteria and kitchen. The two upper
floors will be devoted to offices. The building is
the gift of the Carnegie Corporation of New
York, while the ground was bought at a cost of
about $200,000 through the donations of about a
score of benefactors. Bertram Grosvenor Good-
hue of New York is the architect. He is one of
the best known architects in the country and de-
signed the St. Thomas Church, the West Point
buildings, the Nebraska State Capitol and many
other buildings. The contract for the construc-
tion of the building has been let to Charles T.
Wills, Inc., of New York, and it is expected that
the building will be ready for occupancy in the
autumn of 1923. Lee Laurie, the sculptor, has
been selected to do the decorations, which will
symbolize and depict the progress of science and
its benefits to humanity. A series of bronze bas-
reliefs will show a procession of the leaders of
scientific thought from the earliest Greek philoso-
phers to modern Americans. On passing through
the entrance hall the visitor will find himself in a
lofty rotunda. Here he will see in actuai opera-
tion apparatus demonstrating certain fundamental
scientific facts that hitherto he has had to take on
hearsay. < 1011 calories, or five million
times the energy liberated when the same weight of
hydrogen unites with oxygen to form water. This
is about three fifths of the energy which would
be liberated in the complete change of 238 grams
of uranium into 206 grams of lead, 32 grams of
alpha particles, —6N electrons (where N repre-
sents the avogadro number) and about 0.05 grams
of radiant energy. The energy which would be
liberated in the formation of alpha particles from
hydrogen is so great that it would seem that this
reaction should proceed at an extremely high
speed. That this is not the case may be due to
the fact that for some unknown reason one elec-
tron does not form a very stable union with one
proton, but the common ratio is two of the latter
to one of the former in the most stable aggregates.
Thus it is not improbable that four protons and
two electrons seldom meet at one time in such
relative positions as to allow the alpha particle to
be formed. It may be suggested that the first
step in the building of an alpha particle may be
the formation of the aggregate pe, which is sta-
ble with i but easily
unites with a like particle to form the group
(p,é),, or the alpha particle. According to
Rutherford’s hypothesis the carbon nucleus con-
sists of four groups of the formula p_e. While the
evidence in favor of this assumption is not spe-
cially convincing, there is on the other hand no
evidence against it. However, definite evidence
will be presented which proves that the alpha par-
ticle is the principal group concerned in the

growth of carbon nuclei into those which are
heavier. The composition of any complex nucleus
may be expressed by the formula (D,€) (PE)
in which n represents the isotopic number. This
number varies from 0 to 54 for known atomic
species, and is 0 for most atoms. In the range
in which the isotopic number is small, the most
abundant species of atoms are those whose isotopic
numbers are divisible by 4, while for higher iso-
topie numbers the maxima of abundance are not
so distinct, and occur in general for the isotopic
numbers which are even. The most important
relations which should be taken into consideration
in showing the nature of the general system of
isotopes are: (1) The number of negative elec-
trons in most atom nuclei is even, so in general
the atomic weight and the isotopic number are
both even when the atomic number is even, and
are both odd when the atomic number is odd.
(2) As the atomic number increases the isotopic
number of the more stable isotopes of an element
also increases. This may be expressed as follows:
As the net positive charge on an atom nucleus
increases the atom becomes more unstable unless
at the same time the nucleus becomes more nega-
tive with reference to its relative content of nega-
tive electrons. (3) For any set of isotopes the
atoms become more unstable with reference to a
beta disintegration as the isotopic number
increases, and more unstable with reference to an
alpha particle disintegration as the isotopic num-
ber decreases. This relation does not specify
what form of disintegration will take place in any
special case, since this probably depends upon the
grouping, but it does give the relative rate for
any disintegration which actually does take place.
Obviously this relation has been tested only in
the case of the radioactive elements. The rela-
tions which exist in the general system of isotopes
will be presented in the form of an extensive plot
which exhibits a large number of relations, many
of them periodic, which can not be well treated
in an abstract.

undertaken by the Carnegie Institution of Wash-
ington, U. S. Coast and Geodetic Survey, U. 8.
Geological Survey, the geological departments of
the universities of California, the California Insti-
tute of Technology, and the Bureau of Standards,
with the purpose of gathering precise data bear-
ing upon this subject. It is a part of the pro-
gram not only to locate the surface displacements
either gradual or disruptive, but also to develop
instruments and establish stations for the location
of sub-surface zones of movement.
Geological overthrusts and underdrags:
ressor W. M. Davis, Harvard University (by
title). Overthrust masses of earth crust haye
been found, the front of which has advanced a
score of miles or more beyond its original posi-
tion. On tracing such masses backward, no indi-
cations of a cavity left by their advance have
been found; hence it may be possible that they
have obliquely emerged from beneath rear por-
tions of the crust which have not taken part in
their movement. If so, the rear portions should
exhibit displacements due to what may be called
the ‘‘underdrag’’ of the obliquely emerging
Such displacements would be character-
ized by an increase in horizontal dimensions in
the direction of underdrag, and manifested by
normal faults on moderately slanting fault planes.
The mountain ranges of the Great Basin of Utah
and Nevada appear to exhibit such displacements.
The effects of winds and barometric pressures
on the Great Lakes: Dr. J. F. Hayrorp, North-
western University. The surface of the water of
any one of the Great Lakes is never level except
by accident. It always has a slope in some direc-
tion, produced by the wind, by barometrie pres-
sures, or by the water of the lake oscillating as
if it were in a great wash-basin. The correct
knowledge of these things is a key to various
scientific problems and ultimately will prove to be
worth millions, in their application, to the people
of the United States. It has long been known
that a wind blowing over a lake tends to pile up
the water on the lee shore and to pull it down on
the windward shore. How large is this effect?
Is the response of the water to the wind imme-
diate? It has not been possible to answer these
questions confidently in the past. Now it is
known that the response is prompt and that the
effect of a given wind in disturbing the water
level at any point in the world may be computed
in advance. It is known that the strongest winds
that blow have almost no effect in changing the
Pro-
masses.

water level at various points, as, for example, at
Milwaukee on Lake Michigan and Mackinaw City
on Lake Huron. On the other hand, it is known
that a wind of 50 miles per hour from the south-
west piles up the water a foot at Buffalo and
pulls it down simultaneously more than a foot at
the west end of Lake Erie. The reason for this
extreme contrast between. different places and for
the fact that the wind effect is greatest in long
shallow bays is now accurately known. The lake
surface is also continually tilting up, first in one
direction, then in another, in response to varying
barometric pressures. The water tends to go
toward a region of low barometric pressure and
pile up there. Such effects at Mackinaw City and
Milwaukee frequently amount to three inches or
more, although wind effects at these points are
almost inappreciable. Just as a piano string
struck once, or the air in an organ pipe continu-
ously agitated by a reed, vibrates with its natural
period, so the water of each of the Great Lakes
under the many impulses given it by the winds
and barometric pressures oscillates back and forth.
Sometimes the whole of a lake is concerned in an
oscillation, and sometimes the lake oscillates in
parts. Such oscillations in lakes are called seiches.
Striking similarities between the igneous rocks
of Brazil and South Africa: Dr. H. A. Brouwer.
Striking similarities in geological age and in
composition exist between the old granites and
gneisses with intrusive younger granites, the pre-
cretaceous intrusive sheets of diabase, the lava
flows of the Serra Geral and the Drakensberg, the
pipes and dykes of kimberlite and the intrusive
and effusive alkali rocks (nephelinesyenites, phono-
lites, ete.). The alkali rocks are found on both
sides of the Atlantic Ocean near the coast; they
form denuded volcanic centers and if the west
coast of Africa and the east coast of South
America be considered in juxtaposition the loca-
tion of these older volcanoes would be very sim-
ilar to that of the young voleanoes of alkali
rocks (Kenia, etc.) near the young fracture-
system, bordering the rift valleys in East Africa.
Very long dykes of nephelinesyenites prove the ex-
istence of similar fractures in the central part of
South Africa.
Fauna of the Pleistocene asphalt deposits of
McKittrick, California: Dr. Joun C. Merriam,

The discovery of an enormous accumulation of
perfectly preserved remains of extinct animals
found in asphalt beds in the environs of Los
494
Angeles, California, some years ago furnished
some of the most interesting data on the history
of life thus far secured in America. A similar
deposit representing an assemblage of animals of
a somewhat different type has recently been
opened for extensive investigation on the western
border of the Great Valley of California. Re-
mains of a wide variety of higher animals and
birds were found at this new locality. The col-
lection represents the geological period immedi-
ately preceding the present and offers the best
opportunity thus far known to study the life of
this late geological stage under the conditions
obtaining in the Great Valley of California.
The telephone engineer a public trustee: FRANK
B. JEWETT, vice-president, Western Electric Com-
pany. In his paper, which was a statement of
the unique position which the telephone engineer
of to-day occupies in relation to the general
public, Dr. Jewett outlined the organization of
the communication service of the United States
and pointed out the position and scope of work
of the engineer in this organization. Dr. Jewett
indicated that the telephone art, even at the end
of nearly half a century of the most intensive
development and monumental growth, was still
far from being an agency requiring little or no
change. He showed that the recent developments
in physical science had opened up vast possibili-
ties of new and improved communication services
which the telephone engineer was endeavoring to
make available for public service, and indicated
some of the problems which were being success-
fully attacked. He also pictured some of the tre-
mendous difficulties which confronted the tele-
phone engineer in incorporating these new services
into the existing structure, which was itself grow-
ing rapidly along already developed lines, with-
out producing disruptions of service. Finally he
pointed out that the telephone engineer of to-day
had come to recognize that his function was in
effect that of a public trustee and that his prob-
lem was not alone that of developing new and
improved instrumentalities, but of developing
these instrumentalities and making them available
to the publie without subjecting the telephone
user to annoyance as a result of experimentation
on the public at large.
The loud speaking telephone: FRANK B. JEw-
ETT, vice-president, Western Electric Company.
For many years, and in fact almost from Dr.
Bell’s discovery that human speech could be trans-
mitted to distant points electrically, there has been
incessant quest for a satisfactory loud speaking
telephone. Innumerable attempts to devise instru-
SCIENCE
[Vou. LV, No. 1427
ments of this kind have been made in the last
thirty or forty years and until recently all have
been substantial failures. Recently, however,
really successful instrumentalities have been pro-
duced and the field of possible influence on all
social and human relations which has opened up
was evidenced graphically in the Armstice Day
exercises attendant upon the burial of the Un-
known Soldier at Arlington, Virginia. In these
ceremonies vast audiences in San Francisco, New
York and Washington listened to the President
of the United States and other speakers and
joined in common exercises of respect to America’s
dead. -Dr. Jewett’s paper, which was illustrated
by a local demonstration and by a demonstration
of talking over the regular telephone wires from
New York, described the physical and electrical
problems whose solution had to be achieved in
order to make the loud speaking telephone a
success. He pointed out that the problem con-
sisted essentially of four main elements, namely:
(1) The development of telephone transmitters
capable of picking up the sound vibrations of the
speaker’s voice when the latter was speaking
normally at some distance from the instrument,
and of faithfully translating these vibrations into
electrical vibrations for transmission over the
wires; (2) the transmission of these electrical
vibrations undistorted to the distant point; (3)
the amplification at the distant point of the re-
ceived electrical impulses to an energy value many
times greater than that produced by the trans-
mitter at the speaker’s end of the line; and (4)
the translation back into sound vibrations of these
greatly amplified speech waves through an appro-
priate loud speaking receiver. He pointed out
that if the received speech through the loud
speaking receivers was to be of acceptable quality
no serious distortion could take place in any of
the links of the chain from the speaker to his
distant audience, and that the inherent charaec-
teristics of the loud-speaking system call for even
more faithful reproduction than is necessary in
ordinary telephones of recognized good quality.
He pointed out further that because of the neces-
sity of using ordinary telephone lines, which in
most cases were in close proximity to numerous
other telephone lines used in the regular way, it
was necessary that the currents transmitted from
one end ot the line to the other should be sub-
stantially of the same magnitude as those pro-
duced in the use of the ordinary telephone. He
showed that this requirement, combined with the
necessarily inefficient energy characteristics of the
originating transmitter and the tremendous energy
May 5, 1922]
requirements of the loud speaking telephones had
made the problem inherently insoluble until means
had been developed for producing telephone lines
with very uniform transmitting characteristics and
until amplifying devices of great power, uni-
formity and freedom from inherent distortion
production:had been developed.
The physical examination of hearing and
binaural aids for the deaf: R. L. WEGEL, Western
Electrie Company, New York City. The function
of the auditory sense is to detect sounds of dif-
ferent wave shapes, the ratio of the pressure on
the ear drum varying over a range of
1 : 1,000,000. It must also differentiate between
sounds so nearly alike that no existing physical
apparatus is capable of separating them. Binaural
audition adds a sense of orientation and discrim-
ination together with a more uniform sensitivity
for sounds approaching from different directions.
A binaural set for aiding the hard-of-hearing was
exhibited. An abnormal auditory sense may be
regarded as one lacking to a greater or less de-
gree in (1) range of sensation (frequency or
intensity), (2) quality of sensation in various
regions of the range, (3) binaural sense. Methods
have been studied for exploring the outstanding
elements of these functions. A new audiometer
for measurement of hearing was shown.
The relative sensitivity of the ear at different
levels of loudness: Dr. Donatp MacKeEnzin,
Western Electric Company. Up to the present
time there has been no satisfactory technique for
loudness comparisons of different tones. In this
paper a description is given of an alternation
phonometer which makes it an easy matter to ad-
just to equal loudness two tones of different
pitches. With this instrument a determination
has been made of the relative sensitivity of normal
ears of both men and women, over the pitch range
from bass G to C5, at sound intensities midway
between the faintest audible and the painfully
loud. It is found that the sound energy necessary
to produce a given loudness is smaller the higher
the pitch, at least within the range examined.
Different ears agree more closely at these intensi-
ties than at the least audible, and no difference
is detectible between men and women. Inter-
pretation of the results shows them to be in har-
mony with Fechner’s law, according to which the
difference between the sensations due to two lights
of the same color or two tones of the same pitch
is proportional to the ratio of intensities of the
lights or sounds causing the sensations. This
simple law holds only at moderate intensities.
Phonometric comparisons by a small number of
SCIENCE
495
observers were made at intensities from very faint
to very loud. It appears that any one ear varies
from day to day, but these variations are most
noticeable at the extremes of loudness. The re-
sults taken all together strongly suggest that, on
the average, the relative sensitivity of the ear to
different musical notes is practically the same
whether the sounds are loud or faint.

Ames, The Johns Hopkins University.
Coefficients of slip and the reflection of mole-
cules: Dr. R. A. Minurcan, Norman Bridge Lab-
oratory of Physics, Pasadena. This paper con-
tains a presentation of the theoretical relations
between the coefficient of slip and the law of
reflection of gas molecules from the surfaces of
solids and liquids. It presents, also new experi-
mental data taken by the author and his pupils
which completely check the correctness of this
theory. It gives for the first time the exact ratio
between the number of impinging molecules which
are specularly reflected in the case of a given gas
from given liquid and solid surfaces, and the
number which are diffusely reflected. The most
interesting facts brought to light by the investi-
gation are, first, that this ratio is different for
different kinds of molecules when the nature of
the surface remains constant, and, second, that
there is a larger coefficient of slip between oiled
surfaces and gases than between the same gases
and ordinary unoiled surfaces of metal or glass.
Origin of penetrating radiations of the upper
air: Dr. R. A. Mi~tixan, Norman Bridge Lab-
oratory of Physics, Pasadena. It is of intense
interest to know whether the penetrating radia-
tions which have been heretofore studied up to
altitudes of 9,000 meters are of cosmic or of
terrestrial origin. Pre-war observations made in
manned balloons in Germany gave indications that
they were of cosmic origin. Observations pub-
lished last year from the University of California
were in opposition to this view. Indeed, the Cali-
fornia observers attributed the increase in the rate
of discharge of the electroscopes with increasing
height, as found in Germany, to the effects of
temperature upon the electrical conductivity of
the supports of the gold leaves in the electro-
scopes. The observers at the California Institute
of Technology have definitely proved that the tem-
perature effects upon the supports when the ex-
periments are properly performed are practically
negligible. They are now making balloon flights
in which self-recording instruments are sent up to
the very top of the atmosphere, that is, to a point
at which only one sixteenth of the atmosphere is
496
still above, and should be able to determine with
certainty by these experiments whether the pene-
trating rays are of cosmic or of terrestrial origin.
While the instruments sent up weigh but 175
grams (6 ounces) they are capable of bringing
back a complete record of the temperatures, the
pressure, and the penetrating radiations existing
at all of the altitudes which they reach. These
altitudes should be about three times as great as
those ever obtained before in experiments of this
kind. These balloon flights will be reported later.
On the measurement of a physical quantity
whose magnitude is influenced at random by pri-
mary causes beyond the control of the observer,
and on the method of determining the relation
between two such quantities: Dr. WALTER A.
SHEwHART, New York City. The objects of scien-
tific investigation are twofold, i. e., the determina-
tion of some form of average value and its prob-
able variation, and the determination of the rela-
tion existing between two or more such quantities.
In many problems of physical and engineering
science it is possible to assume that causes of
variation of the variable under consideration may
be controlled by the observer. Certain problems
in these sciences as in the fields of economics and
biology arise, however, wherein it is impossible to
control the causes of variation, and they must be
submitted to a statistical method of solution. An
outline of the necessary analysis is given and
illustrated. Application of the theory of correla-
tion and its physical interpretation was discussed.
Ether-drift experiments at Mount Wilson in
1921 and at Cleveland in 1922: Proressor Day-
TON C. MILLER, Case School of Applied Sciences,
Cleveland, Ohio. The Michelson-Morley experi-
ment to detect the relative motion of the earth
and ether was performed at Cleveland in 1887.
In explanation of the null result then obtained,
the Lorentz-FitzGerald effect was proposed. The
experiment was repeated by Morley and Miller in
1904, with a much larger and more sensitive ap-
paratus, which was also especially arranged to
make a direct test of the Lorentz-FitzGerald
effect. Again a null result was obtained. The
suggestion was then made that the earth drags
the ether, and while there is no ‘‘drift?’ at the
surface of the earth, it might be perceptible at an
elevation aboye the general surface. The experi-
ment was again performed by the present author,
at the Mount Wilson Solar Observatory in March
and April, 1921, where the elevation is nearly
6,000 feet. The results indicated an effect such
as would be produced by a true ether-drift, of
about one tenth of the expected amount, but there

was also present a periodic effect of half the fre-
quency which could not be explained. The inter-
ferometer had been mounted on a steel base and
in order to eliminate the possibility of magnetic
disturbance, a new apparatus with a concrete
base and with aluminum supports for the mirrors
was constructed. Observations were made in
November and December, 1921, the results being
substantially the same as in April. Before any
conclusions can be drawn, it is necessary to deter-
mine the cause of the unexplained disturbance.
The interferometer has again been mounted at
Case School of Applied Science, in Cleveland, and
observations are now in progress, the results of
which were reported in this paper, which was
illustrated by lantern slides and motion-pictures.
About 700 feet of motion-picture film was taken
at Mount Wilson by a member of the observatory
staff, showing the location and construction of the
apparatus and also the method of making the
observations.
Some extensions in the mathematics of hydro-
mechanics: Dr. R. 8. Woopwarp, Washington,
D. C. The most general specification of fluid
motion requires a minimum of twenty symbols,
or factors. Of these the most important are the
three velocity components, the three spin com-
ponents, and the four potentials from which the
velocity components are derived by differentiation.
The first part of the paper shows how it is more
advantageous, in general, to make use of the rela-
tions between the Laplacians, or the Laplacians
of the Laplacians, of these factors, than it is to
make use of the relations of a lower order. It is
shown that this extension greatly systematizes
and simplifies the statement and the solution of
problems on the motion of viscous fluids. The
second part of the paper refers to what the author
has ventured to call preharmonies, which are the
triple integrals of harmonic functions which figure
extensively in hydromechanics. It is shown how
to find all of the preharmonies corresponding to
all of the harmonie functions of positive and
negative integral degrees.

PSYCHOLOGY
“ASTUDY OFMENTAL LIFE
By ROBERT S. WOODWORTH
Professor of Psychology in Columbia University
“T have no hesitation in pronouncing Professor Woodworth’s ‘Psychology’ the most
distinctive and significant contribution to the collection of texts on this subject that has
appeared in recent years.’—JosEPH JAstRow, University of Wisconsin.
“In my opinion it is the clearest, and most readable presentation of the subject that
exists at the present time. The author’s happy faculty of taking everyday illustrations and
making the psychology residing in them apparent is worthy of comment.’—A. M. Jorpan,
University of Arkansas.
“His dynamic emphasis is evident not only in his treatment of the human mechanism
from a more or less behavioristic viewpoint but also in his study of the conScious life and of
personality development. The breaking up of the topic of the nervous system and its in-
cidental presentation with the appropriate sections of the behavioristic psychology is an ex-
cellent point. What is also to be recommended is the style of writing—it is the most
effective for presentation to undergraduates I have ever seen.”—J. F. DasuieLt, University

The Bovie H-ion Potentiometer
for the
Chemist, Biologist and Bacteriologist
The Bovie H-ion Potentiometer facilitates the determination of acidity or
alkalinity of solutions.
The indications of the instrument are given directly in terms of
H-ion concentration.
The actual reaction of a solution for a given condition may be
determined by a single reading, or a curve may be developed
(semi-automatically) showing the changes in the actual reac-
tion with changes in the condition of the solution.
A curve so developed gives data for determining the total reac-
tion of the solution.
This instrument especially facilitates the work of the bac-
teriologist in adjusting the reaction of culture media to some
definite value.
The standard cell, galvanometer, and rheostat of the potentiometer circuit
are contained within the instrument. External pieces required are a storage
or dry cell and the electrodes with their accessories.
Bulletin S767 describes the Bovie H-ion Potentiometer.

THE FACTOR OF SAFETY IN RE.
SEARCH!
ONCE in the drear dead days unfortunately
still fresh in memory the head of a great insti-
tution for the aid of education wrote, with
reference to research, these words: “In the
last two decades more sins have been com-
mitted in its name against good teaching than
we are likely to atone for in the next genera-
tion.” Evidently the time of reformation had
not arrived when this disparagement was
uttered, for some ten years later the same pen
recorded history as follows: “Much of that
which has gone on in American universities
under the name of research is in truth only an
imitation of research.”
To some of you, more than commonly zealous
in support of investigation and with a back-
ground of rural experience, these words may
come with memories of the odor of new mown
hay and visions of waving yellow fields and
the reflection that excessive heat sometimes
causes mental aberrations. For the quoted
passages could have come only from an annual
report, naturally written just after the end of
the fiscal year; but unfortunately for this
simple explanation, the fiscal year of the insti-
tution in question does not end in June, and
the derogation of research was conceived in
the cool gray days of autumn. Moreover no
charge of alienation of reason could be brought
against the author of these rebukes that would
not lodge with equal justice in other quarters.
The chief executive of another great institution
which has done and is doing as much in the
field of research as any of its kind in America
voiced a similar sentiment thus: “Quite too
much attention is paid to those who when they
make some slight addition to their own stock of
information fancy that the world’s store of
1 Address of the President of the Michigan
Academy of Science, Arts and Letters, March

498
knowledge is thereby increased by a new dis-
covery.” It is not fair in this case to remove
the quoted words from their context, which
was really a commendation of research as a
university function. But in view of the wari-
ness with which such views are expressed in
public, the slight stricture here permitted to
appear is probably only the weather-worn out-
cropping of a stratum much more extensive.
Indeed, it is not an uneommon idea even
among men actively engaged in investigation
that there is a fearful waste of energy upon
research that might as well be left undone. Has
it not been pointed out in every discussion of
cooperation in scientifie work how much better
would the world be served, could the labor now
being frittered away upon unimportant mat-
ters be organized under the direction of some
one capable of separating the wheat from the
chaff? A few years ago Edwin Linton, in an
appreciation of Spencer Fullerton Baird, who
must have been a practical person to have
deserved the commendation bestowed upon
him, wrote: “I am led to wonder if the failure
of science to influence legislation in the inter-
ests of the people is not to be charged to the
propensity on the part of these leaders to shun
the practical.” Likewise the energetic chief
of the Federal Bureau of Entomology, on look-
ing through a collection of doctor’s theses with
the interests of his own bureau in mind, finds
“that only a very small percentage of this out-
put represents work which ean be of the slight-
est use to humanity in its immediate problems
regarding the insect world.” “At present most
of the best men are working away in their
laboratories practically heedless of... the
tremendous necessity for the most intense work
by the very best minds on the problem of over-
coming and controlling our strongest rivals on
this planet.” Had Dr. Howard been a phys-
icist, or engineer, or metallurgist, he could no
doubt have changed a word here and there and
made the same statement with equal vigor.
Those of you who every May have scanned a
series of doctor’s theses may wish to explain
in some other way the fine despair with which
he exclaims, “And how can we emphasize the
prime importance of devoting our earliest
attention to those problems which most imme-
diately concern our well being.”
SCIENCE
[Vou. LV, No. 1428
These are not the only investigators who
have views that substantially agree in regard-
ing much research as wasted, and the number
who are willing to express such views in public
is presumably but a fraction of the number
who hold them in private.
Research is not, it is true, alone in including
much which is of no direct value. How much
of literature could not be suppressed, to the
advantage of author, publisher and reading
public? Is there not much of so-called art
which might never have been born, and leave
the world happier for its non-existence? How-
ever, to recite the ills of sister lines of en-
deavor is not to eure or even excuse our own.
But are they ills? Is it to be in any wise
deplored that the research by which John
Brown wins a degree, or Professor Jones keeps
his mind fertile while teaching, is not of the
sort that promises to lighten the burdens of
human society or inerease its means of
pleasure? At least, is it to be deplored to the
extent that Student Brown and Professor
Jones should have refrained from research if
they were unable to fix upon a more practical
subject of investigation? I believe it is not
only not to be regretted that some pieces of
research must seem trifling, but that the system
under which we now operate, in which un-
important or perhaps in themselves valueless
contributions are sometimes made, accom-
plishes a greater result than any system that
could be devised under which such insignificant
researches would be excluded.
Let me disillusion at once those who imagine
that I am about to defend research on the ideal
ground that truth for truth’s sake is indeed
practical, and that therefore any investigation
which discovers a grain of that precious com-
modity is an economic gain. I would be will-
ing to make such a defense if it were desirable
to pitch the combat on so high a plane. But
it is no time to wrestle with the angels above
the clouds while the forces of evil are unvan-
quished in the valley. I have no intention of
discussing at length what is practical. Per-
haps one should regard general knowledge as
the most practical kind. The elimination of
ennui and of the loose habits formed in the
periods of mental vacuity to which the ig-
norant and the merely technically trained are
May 12, 1922]
frequently subjected may result in improved
health and increased longevity, and so be a
highly practical matter. An engineer or a
physician seldom reaches the economic heights
of his profession without the engaging or com-
pelling mental exterior which only a general
education can develop to the full. One need
not admit that only those things are practical
which look practical to the world at large. One
need not even admit that a thing is useless even
if it could be known—as it can not—that no
better food supply, or no decrease of hardship
would ever come out of it. The conception of
the practical which makes it include general
knowledge is capable of strong support, but I
shall not avail myself of it. I propose to ac-
cept, for the purpose of this address, the
definition of the practical as given by the man
in the street.
Nor have I any intention of deciding
whether a practical education is the best one.
So far as I can see, the whole science of
astronomy might be forgotten, and my present
daily life would go on about as before. I
would enjoy the sunlight and profit by its
energy as I do now. The seasons would follow
one another in the same order if we were
ignorant of the causes of their succession. The
eugenic effects of moonlit and starlit nights
would be as great as at present. Should the
navigator who brings me comforts from dis-
tant parts of the globe get into trouble, that
difficulty could soon be obviated. But one ele-
ment of vastness in the thoughts of men would
be gone forever, and it is not unlikely that
experiences of other kinds would shrink in
proportion. What physical advantage, gained
by devoting to some applied science the energy
now devoted to the planets, could compensate
for such a loss?
It is not my purpose, however, to address
myself to idealists, though no doubt that is the
character of this audience. Arguments on a
lower level are now much more urgent. We are
all familiar with the investigations which have
been undertaken for the simple purpose of dis-
covering scientific truth, but which afterwards
have led to results of the highest practical im-
portance. Biologists know by heart the story
of Professor Harrison who by painstaking ex-
SCIENCE
499
periments devised a means of keeping alive a
small group of cells after removal from the
body of the animal to which they belonged, and
of watching them grow under the microscope.
He was seeking to demonstrate a principle of
morphology and development, and he _ suc-
ceeded to the satisfaction of himself and his co-
workers. Neither he nor they considered the
possibility that his method of tissue culture
would ever be used to the obvious advantage of
man. But this method was later used by a
great surgeon, who kept tissues alive for years
and who pointed out the possibilities which the
method contained of disclosing the causes of
death and thereby of prolonging human life.
Thus the experiments first used to settle a dis-
puted question of biology promise, in the opin-
ion of many, to bring us nearer to that oldest
of human goals, the fountain of eternal youth.
The possibility of practical advantage to be
derived from these culture methods weighed
heavily in the allocation of the Nobel prize in
medicine which was bestowed upon the sur-
geon. There should be no detraction from the
credit due to one who has the vision to discover
new uses for old methods, but rather increase
of eredit to the original discoverer. Professor
Harrison would be the last to ask that the
Nobel prize be transferred to him. All he
would ask is that research in general be sup-
ported in a broad way which will occasionally
make possible further practical applications.
Perhaps less generally known is the recent
improvement of submarine cables, whereby
their capacity is increased five-fold. Experi-
ments extending over a long period of time had
as their aim improved insulation which would
prevent or reduce leakage. ‘These efforts suc-
ceeded to a marked degree only after another
worker, with the mere advance of scientific
knowledge in mind, invented a new alloy hav-
ing the desired insulating properties. The field
of physies is full of such examples. The work
of Maxwell on the electromagnetic wave theory
led to wireless telegraphy; Roentgen’s rays
were discovered in the course of a piece of
pure research; and, indeed, all of the early
work on electricity was done in a spirit of
investigation having no other object than to
discover the truth.
500
What might have happened to these dis-
coveries had they promised to emerge in an
atmosphere in which it was considered that
“much that has gone on in the name of re-
search is in truth only an imitation of re-
search,” can only be surmised. Whether they
would have been made in the laboratories of
an institution where they stood a chance of
being regarded as “sins against good teaching”
so heinous as to demand expiation for a gen-
eration, may be doubted. Even if their worst
prospective reception had been that of being
regarded as slight additions to the discoverers’
own stock of information and not an increase
of the world’s store of knowledge, their origin
could hardly have been inspiriting to their
author. One pauses to meditate upon the rea-
sons for the long delay in the appreciation of
the work of the Abbé Mendel in hybridization
ot garden peas, and of that of Willard Gibbs
on the “phase rule,” and to wonder whether
even then men in positions of influence were
convinced that they could “spot’’? in advance
those’ things which were worth doing.
It would be hazardous to assert that cases as
striking as the foregoing are common. Less
spectacular examples are, however, not rare.
Although many of the economically valuable
applications of science -to practical ends are
directly made by investigators who are con-
sciously striving to make those applications, it
is probably in every ease true that their suc-
cess has depended upon previous discoveries
not made with a practical aim in view. Some
one has gone so far as to say that every dis-
covery of science which has proven of economic
use was first made as a contribution to pure
selence.
Justification of research along lines that
promise no amelioration of man’s condition
must not, however, lie only in the possibility
that the amelioration will result even without
the promise. Some investigations must be ear-
ried on purely for the training of investigators.
Until, by use of tissue cultures or an analogous
procedure discovered by the pure scientist and
then applied by others, some means of indef-
initely prolonging life is discovered, new inves-
tigators must be developed to replace the old.
New investigators are developed only by prac-
SCIENCE
[Vou. LV, No. 1428
tice, and in practice they must solve problems.
For this educational work a problem of small
value often serves as well as a weightier one.
Indeed, since first attempts often show the
hand of the novice, it may be doing a real
service to science to withhold the more serious
problem for a second or later investigation. It
is not reasonable, therefore, and perhaps it is
not wise to insist that even the training of
research students shall all be done on subjects
that are in themselves of high value either
directly or indirectly. Objecting to our system
of traininig in research by means of small
investigations that are not in themselves im-
portant is like proposing to abandon the study
of arithmetic by means of problems on the
ground that no one ever bought seven gallons
of vinegar at twenty cents a quart, and that
therefore it is a waste of time to discover how
much the liquid cost.
To convinee ourselves that the rearing of
young investigators on a diet of insignificant
problems is not inevitably fatal, and that it
may even be beneficial, it is only necessary to
look backward instead of forward, and gather
assurance concerning the future from what has
happened in the past. -Did Pasteur, for exam-
ple, learn the art of investigation on a problem
that he foresaw was to be a lasting boon and
cause of untold happiness to men? This being
a presidential address, I will probably exhibit
no greater degree of ignorance than is to be
expected if I inquire whether the solution of a
puzzling problem relating to the isomeric tar-
taric acids was by any one at that time held to
be full of economic promise. Molecular strue-
ture we may regard to-day as of high im-
portance, perhaps in some instances even in a
practical way, but hardly in Pasteuv’s early
manhood. That his researches were considered
by his contemporaries futile, even from the
pure science viewpoint, is plain; for when
Pasteur’s reputation had been established,
when he was professor of chemistry, even when
he was dean of his faculty, than which no
higher honor presumably could come to a man
of science, he was advised by Biot and Dumas,
veteran chemists, not to waste more time on
the subjects which were then uppermost in his
mind. These investigations led, however,
May 12, 1922]
through the chemistry of fermentation to the
bacteria of fermentation, and thence to the
organisms of disease, and to-day the appre-
ciation of the practical value of Pasteur’s work
is universal.
We may be told that Pasteur could have
started midway in his career if some one had
put him there at the outset by advice; and if
we reply that there was no such person to ad-
vise him, we may be reminded that there are
plenty of advisers to-day. These advisers are
precisely the foundation on which those who
decry the uselessness of many present investi-
gations propose to build a system in which
only useful and important projects are under-
taken. Granted an abundance of omniscient
advisers, their plan should work; but if these
foundation stones prove defective, the struc-
ture resting on them will fall. How readily
such advisers may be discovered and drafted
into service is perhaps capable of computation.
No doubt each person who proposes to elim-
inate uselessness in research has in mind at
least one who is able and willing to undertake
the task of elimination. Otherwise the proposal
would hardly be made. One need, therefore,
only count the number of those who would dis-
pense with impractical investigation to deter-
mine the minimum number of advisers with
which the system might start. Probably there
are others having ability, but also modesty,
who can not be immediately discovered. So
far as I know no one has attempted to deter-
mine how much leadership a federation to pre-
vent uselessness in research might count upon.
There is danger in this connection that the
controlling factor of a career be misjudged.
Careers are only occasionally guided by advice;
for the rest, they are the product of evolution.
Each step depends on what has gone before,
and determines what shall come after. Granted
the characteristics with which Pasteur’s parents
endowed him, his life proceeded naturally from
one thing to another. One need not be a
fatalist to conceive that the only way for him
to end with proof of the germ theory of dis-
ease was to start with isomerism in tartaric
acids. Had he been artificially set down at
some mile-post on the way, without having
traversed the preceding distances, it is ques-
tionable whether he could have been made to
SCIENCE
501
follow the same road, even with the help of
advice from those who believed they were qual-
ified to give it. Without the abiding faith that
he was on the right road, which only his own
previous work, not the suggestions of his
elders, could give him, it is scarcely likely he
would have persevered through the long periods
of discouragement. To him who asserts that
Pasteur could have been put upon the problem
of pathogenic organisms in his early days and
have reached the goal of his maturity at an
earlier date, the only suitable reply seems to
be the verse which might prove to have apos-
tolie origin if the Scriptures recorded every-
thing, “Verily, optimism hath its own reward.”
Had Pasteur’s hypothetical early start on
pathogenic organisms failed to lead him to the
present conception of the etiology of disease,
what would have been the damage? Would
the world simply have lost Pasteur, and never
been the wiser, in the same manner as it has
probably lost many another genius, perhaps
through mistaken advice coming from those
who were supposed to know? Could humanity
have counted on a substitute for Pasteur, aris-
ing at an equally early date and arriving, either
with or without advice from superiors, at the
same conclusions as Pasteur reached? It is
not likely. Failure to discover the truth by
Pasteur would have been a calamity. His
work would have been careful, painstaking.
Everyone watching his later career would have
recognized that his work on the theory of
pathogenic organisms must have been thor-
ough. But, owing to immaturity, or want of
perseverance because he lacked the faith in his
own hypotheses which only gradual develop-
ment of them could insure, it had demonstrated
nothing, its results were negative. Surely this
would not have been an encouraging fact for
any one else who conceived the germ theory of
disease and contemplated efforts to prove its
correctness. The oligarchy set up to guide re-
search in useful directions would hardly have
advised young men, or others, to enter that
field. The fact that careful work by an able
investigator, even if then young, had failed to
find any proof of the bacterial origin of dis-
ease, could easily have damned the truth to a
generation or more of undiscovery.
If any comfort is to be taken in the gloomy
502
picture of what would have happened if
Pasteur had, at the behest of some supervising
agency, undertaken as a first problem some-
thing else than the isomerism of tartaric. acids,
and thereby missed the germ theory of disease,
it must lie in the belief that a man of Pasteur’s
timber would have done great things in another
field. But such a consideration does not
answer the argument that his early work, prac-
tical or not, was a necessary training in order
that his maturer work might be valuable.
Doubtless the case of Pasteur can be dupli-
cated by that of other eminent scientists whose
first research seemed to bear no relation to
their later high attainments. Perhaps that is
regularly true, except in the small number of
cases in which by the laws of chance it is to be
expected that preliminary work and eventual
important discoveries shall lie in the same field.
The fields in which the accomplishments of
great investigators lie may thus appear to be
matters of accident; but then, an accident is
but the inevitable consequence of other acci-
dents that have gone before.
If it is not fatal, but sometimes even useful,
to start the new investigator on his way with
a problem whose solution promises no practical
improvements in human affairs, what is to be
said of those who are mature in research?
Probably most of these trained workers would
be better satisfied with their showing to their
fellow men, even if not more content with
themselves, if they could be perpetually en-
gaged on practical projects. Even if it be
granted, as has been done in the introductory
remarks of this address for the sake of limiting
the discussion, that practicatly useful investi-
gations are the only ones desirable, is it pos-
sible to maintain a system of research in which
only practical things are attempted, and make
it work? For various reasons the practical
problem that suggests itself to an investigator
may be one which he can not undertake. Lack
of facilities readily accounts for many such
eases, geographical position for others. The
problem that seems most feasible may not seem
highly important even from the pure science
point of view. What is the investigator to do
under these circumstances? Refrain from
undertaking a problem which he feels sure is
SCIENCE
[Vou. LV, No. 1428
not of great value? Even if that means doing
no research at all? Perhaps. But if he de-
cides to keep on working, he may take comfort
in the story of the foolish virgins, and reflect
that in his small way he is keeping his lamp
trimmed and burning even at the cost of some
oil which seems wasted, until the bridegroom
cometh with a problem that is more worth
while. For nothing is so quickly fatal to re-
search as interruption of it. This university
furnished, for valuable war work, some inves-
tigators whose previous work was regarded
even by themselves as of small value. I am not
speaking of any of you here present. The
gentlemen to whom I refer are in their labora-
tories to-night. They find the labors to which
the great conflict introduced them so pleasur-
able, nay, even enthralling, that they have no
time to listen to mere presidential addresses.
The life of any eminent scientist of the present
generation would probably furnish a further
example of the ad interim value of unimport-
ant research. At least this is true of those in
my own field upon whom I have taken the
trouble to reflect. They have engaged in con-
tinuous investigation, the continuity being due
in part, in every case, to insignificant produc-
tions. It is very seldom, and then only under
unusual circumstances, that a serious interrup-
tion is followed by a return to high produc-
tivity.
Nor must it be forgotten that many men
who are engaged in research of minor value
are the trainers of new investigators who may
be more “lucky” than themselves. I think with
profound respect of the professor of physics
in a small western college who keeps working
in a small way, who has never made a striking
contribution, practical or otherwise, to his
science, but who every year or two sends to a
great eastern university a graduate student.
Although these students are most of them still
young men, they have done creditable things,
some of them practical. Is it likely that the
professor in the small college could thus inspire
his students to a career of learning without the
stimulus that comes from his own research?
You may answer this question to your own
liking, as I am doing. In a vicarious way, this
man seems likely to exert upon his science an
May 12, 1922]
influence out of all proportion to the imme-
diate significance of his own investigations.
My challenge to the critics of the present
system of research to produce anything better
does not rest on the idealistic argument that
truth for its own sake is the highest aim of the
scholar. This argument might not appeal to
those for whom this address is intended, who,
while not present in this audience, may yet
receive the challenge. It rests on the demon-
strated fact that many discoveries thought un-
important when made have proven to be valu-
able later, on the belief that new investigators
are often as successfully prepared by unim-
portant practice problems as by more funda-
mental ones and with sometimes less danger to
the progress of science, and on the assumption
that the continuity of labor which problems of
small value permit is conducive to aggregate
high productivity. This is the system under
which we now operate, a system which leaves
the individual free, and which does not chide
him too severely if he sometimes engages in
insignificant labor. It is a system which pro-
vides for the doing of many services in order
that some of them may prove valuable. Can it
be improved upon? Quite possibly. Can it be
improved upon by attempting to suppress all
efforts that seem to have no significance? I
think not. The principle of this method is one
which has been widely adopted in other affairs
of life and has been found good. Firing a
whole cartridge full of shot in order that one
ball may bring down the game is a recognized
principle of the huntsman. Is the remaining
shot wasted? It is. Is the system which uses
cartridges of shot, most of which is wasted, an
uneconomical one? Any hunter will tell you
it is not. The bullets of a machine gun are
mostly wasted, but the system as a whole
insures hitting the mark. Drilling wells that
never yield oil is wasteful; but the system of
drilling numerous wells where there is a chance
of striking reservoirs is a profitable one. Cast-
ing bread upon the waters, to return again
sevenfold in the form of flesh of fish, would be
much more profitable if all the bread, instead
of being cast at random, could be put into the
mouths of those fishes that were afterwards
going to be caught, and denied to those that
SCIENCE
503
would later escape the net. But could such
individual feeding be carried out? Not eco-
nomically; not even at all. Casting bread upon
the waters is the easiest and least wasteful way
of obtaining a return. Hundreds of inventions
are made for every one that fills an important
place in human economy. Numerous excur-
sions, genuine or spurious, were necessary
before the north pole was discovered. Busi-
ness concerns by the hundred are established
and succeed or fail, but by only a few of them
is economic progress made. Thousands of stu-
dents must be gathered into colleges, so that a
few scholars may be produced. Even presiden-
tial addresses are subject to the same rule. In
order that a few of distinction may be pro-
duced, many that fall short of the goal must
be written and heard. If presidential ad-
dresses must be had, trial and error is the only
way to secure quality.
The factor of safety has been employed for
ons in animals, which waste millions of eggs
and spermatozoa to insure continuity of the
species. Professor Jennings, in one of the
brilliant presidential addresses to which refer-
ence has been made, pictured himself as the
accidental product of union of one among
thousands of eggs and one among millions of
sperms, and congratulated himself on being
with us. We congratulate ourselves on having
him with us. Along with Jennings, it is true,
we have to accept a lot of inferior persons. We
even have to take those who decry research be-
cause much of it is useless. But these disad-
vantages, these wasted combinations, are what
insure such as Jennings. Only a small per-
centage of seeds ever germinate, and fewer
still ever mature. The entire struggle for ex-
istence is based on the principle that security
and advancement are -best secured through
wasteful over-production.
So in research. To find radium, we must
permit scores of fruitless efforts in chemistry.
To invent the wireless telephone, there must
be numerous investigations that concern
humanity little or not at all. To discover the
mechanism of heredity, some one must be per-
mitted to do much that has little or no bearing
either upon that or upon anything else worth
while. The great advances of the theory and
504
practical employment of electricity, of indus-
trial chemistry, of immunity, of surgery, all
have been made at the cost of much plodding
and puttering. It is doubtful whether they
could have been made in any other way.
The foregoing defense of the present free-
dom of the investigator is not to be regarded
as a recommendation of still further freedom.
It is not proposed that young investigators
shall be delivered from all advisers. No
muzzle is to be placed upon those who have
comments to make upon the value of the work
of their colleagues. Restrictions laid upon ad-
vice and criticism are likely to be as dangerous
as restrictions imposed upon problems for
investigation. All that is insisted upon is that
no such advice or criticism shall carry with it
any weight that is not inherent in the advice or
criticism itself. Those in whose hands lies the
power to make or mar the career of investiga-
tors should be exceedingly cautious how they
ereate an atmosphere that seems in any way
to discourage or limit the freedom of research.
I have referred in my introductory remarks
to several instances in which responsible offi-
cials have, in my opinion, transgressed in this
regard. They are not the only ones, and there
are other ways of committing the same sin.
One of these ways is the appointment of an
investigator to a position for the purpose of
studying a certain problem. There comes to
my mind one such appointment in a research
institution. The appointee was, in his own
words, “brought down here to study 4
—but to name the specifie problem would be
to name the institution. He did not feel free
to attack another problem until that one was
solved. It made no difference that he had
come vaguely to feel that the problem would
never be solved, or that other investigations
would yield greater returns. By the terms of
his appointment, his energy could be directed
into other channels only with the permission
of his superior officer. Such direction from
above could be justified only in the case of an
assistant or an investigator on temporary ap-
pointment, not in the case of a permanent
colleague. Research in a general field may
legitimately be the aim of an institution in the
appointment of an investigator, and the ap-
SCIENCE
[Vou. LV, No. 1428
pointee would naturally be one who had demon-
strated an abiding interest in that field; but
even in such cases, the progress of science de-
mands that he be free from restraint.
Very different from such interference is the
friendly advice of a teacher or the criticism of
a colleague. Advice and criticism carry no
concealed weapons. They are sometimes good,
and to repress them eliminates the good with
the bad. Indeed, good advice is more easily
frowned down than is the bad. If my argu-
ment were regarded as against the giving of
advice, and were taken seriously, those whose
advice is best would be the most restrained by
it. The greatest freedom of suggestion from
all sources is advantageous, for advice is some-
times good, and to get what is good one must
also hear the worthless. That is the reason for
this address—and this statement may be inter-
preted in any way you choose.
To sum up, a successful system of research,
even when the practical is the ultimate aim,
demands the greatest freedom of the investi-
gator. While direction from superiors may
effect gains in limited fields, the losses entailed
in the whole system are probably invariably
greater. Great industrial concerns maintain
staffs of workers whose tasks are assigned to
them, and such startling achievements as the
wireless telephone have resulted from their
directed energies; but the responsible heads of
these enterprises recognize that untrammeled
research in pure science must precede and build
the foundation for their labors, and some of
these industrial institutions are now deliberate-
ly maintaining research workers in fields which
promise at present no practical results what-
ever. The freedom which is insisted upon for
the investigator will, it is expected, often lead
him to problems that have no practical value,
or eyen no great scientific value. But a system
in which such liberty is a cornerstone insures
a continuous output and a wide range of re-
sults. Among these results are most certain to
be some, perhaps many, of practical value.
Any interference with this system which would
limit investigations to those of supposed im-
portance would interrupt their continuity, limit
the output, restrict the variety, and defeat its
own purpose. The development of a scientific
May 12, 1922]
foundation is an evolutionary process. Man
has never yet interfered very successfully with
the great scheme of organic evolution, and
there is no reason to suppose that he can pro-
pose a superior substitute for the evolutionary
process in the development of science. Selec-
tionists have practically abandoned the belief
that they can create new things at will, and are
content now to discover, preserve, and combine
what already exists or what may come into ex-
istence without their aid. Practical scientists
may well take their cue from the selectionists,
permit investigation to take its own course,
and choose from among its products such as
seem capable of application.

WHAT BECOMES OF THE FUR
SEALS
THe census of Alaska fur seals in 1921 as
computed by Mr. Edward C. Johnston, of the
U. 8. Bureau of Fisheries, amounted to a total
of 581,457 animals, exclusive of 22,546 surplus
males which were killed for commercial pur-
poses. This is a low but substantial increase
of 5.2 per cent. over the figures for 1920. The
annual percentages of increase of the class of
breeding cows since 1912 have been as follows:
Since it is this class which is the controlling
element of the herd it will be instructive to
examine these figures with considerable care.
In the first place, the great variation from year
to year in the rate of increase is most notice-
able; but it is no greater than that which is
found to exist on the several rookeries, as an
examination of the complete reports published
by the Bureau of Fisheries will show.
To some persons the above figures may ap-
pear satisfactory. Every year since the cessa-
tion of pelagic sealing in 1911 a gain has been
SCIENCE
505
shown, whereas a loss was sustained from 1886
to that date. It was during this last period
that uncontrolled slaughter of the females de-
veloped and threatened the very existence of
the species before it could be checked through
diplomatic channels.
Others will doubtless ask, “Why have the
increases been so low?” A species of animal
the female of which brings forth one young
each year and approximately ten in a lifetime
should increase annually more than 8.98 per
cent. on the average. But that is all that an
average of the above percentages will show.
Several facts have been learned the past few
years which throw some light on this important
subject. For instance, it has been found in
several successive years that only one half of
the females which are born live to be three
years old. The loss of the class on the islands
before the pups learn to swim is about one per
cent. It varies from three fourths of one per
cent. to one and one half, depending entirely
upon how many bulls more than necessary are
present on the rookeries. The annual loss of
females through actual killing on the islands
does not exceed 75, or less than five hundredths
of one per cent.; all such deaths are purely
accidental and largely unavoidable in the con-
duct of commercial work.
Therefore, the loss can take place in but one
other place and that is in the sea. The figure
of 50 per cent. loss the first three years was
obtained in the following manner: The loss of
breeding females, due to old age, is about 10
per cent. each year because the average breed-
ing age is about 10 years. If this 10 per cent.
be deducted from the number of breeding
females in any year, say 1915, the remainder
will represent the breeders of that year which
remained alive in 1916. If this be taken from
the total number of breeders in 1916, the last
remainder will represent the increment of new
three-year-old cows that year because the first
young are born the third year. In several
seasons this increment has been only about 50
per cent. of the number of female pups born
three years previously. In other words, the
loss amounts to one fourth the total number of
births in any one year. Out of the females
born during the last nine years, therefore, the
following losses have been suffered:
506

The great question is, “What has become of
this enormous total of 300,000 female seals?”
Some are killed by unlawful pelagic sealing.
A few bullets and buckshot are found in the
carcasses of males almost every year on the
killing fields, although no seal can be shot
legally. The number so killed, however, must
be insignificant and the work sporadic in char-
acter up to 1921. While it should not be
ignored by any means, it is not sufficiently
great to concern us in such a broad analysis
of the subject as we are here making.
Some other females are lawfully killed at
sea by Indians under the provisions of the
treaty of December 15, 1911. The number so
taken in any one year is not excessive, a few
hundred at most, yet it is sufficiently great that
it should be stopped. The object of the treaty
mentioned was to abolish pelagic sealing so as
to protect the female seals. Therefore, per-
mitting the work at all defeats the main pur-
pose of the agreement and the objectionable
clause should certainly be amended at the first
opportunity. The Indians were given the
privilege because they had hunted seals at sea
from prehistoric times. There are many ways
in which the natives can be recompensed with-
out permitting them to destroy the important
element of any species of wild life.
There is no evidence of any loss of seals at
sea due to disease or starvation. The animals
are always fat and healthy when they leave
their island home and also when they return.
1It should be explained that in fur seal census
computations, while the figures appear exactly as
though a precise enumeration had been made, only
reund numbers are intended to be implied. The
possible error in the above computations would
be approximately plus or minus five per cent.
SCIENCE
[Vou. LV, No. 1428
Exceptions to this rule are so rare that they
may be entirely ignored.
There is only one other known method by
means of which the herd suffers a loss in the
sea. This is the result of the depredations of
killer whales. Each spring and fall these
“wolves of the sea” come about the Pribilof
Islands in schools and have been seen to devour
seals in large numbers. I once saw a school
capture three seal pups in less than five min-
utes. In their eagerness to capture their prey
they sometimes “run aground” and of course
then die. The stomachs of two which thus
came ashore were once examined by Captain
Bryant and in them he found 18 and 24 seals,
respectively, $2,000 meals each of them.
That the destruction of seal life about the
islands by the killers is very great is incontro-
vertible. Whether it continues as both animals
migrate southward is unknown. We know with
a fair degree of accuracy the direction and dis-
tance traveled by the seals but the habits of
the animals during the long period of their
lives when they are in the water are practically
unknown.
There may be other pelagic enemies besides
the killers, but it is doubtful; if so, they are
entirely unknown.
Of course, the males suffer as great a loss
as the females and there is some evidence which
indicates that it is even greater. As a class the
former do not swim so far to the southward,
and it is possible that the killers normally re-
main in the colder waters. At any rate, we
know that 300,000 of them have been lost
during the past nine years. If they had been
taken commercially and their skins sold for
revenue they would have brought the enormous
total of $15,000,000, upon the assumption of a
value of $50 per skin. But during much of
this period they brought $100 each or more.
Such financial loss to the government can
not be passed unheeded. That sum would have
paid for all of the scientific investigations, good
and bad, which have ever been made of the fur
seal. Hach year the actual loss amounts to
more than $1,000,000.
It has been urged that a small part of this be
used for the study of this new “fur seal ques-
tion.” Seldom does a scientific investigation
May 12, 1922]
have such a chance to show immediate financial
results as this. If the activity of the enemy
could be reduced one per cent. it would increase
revenue over $10,000 per year.
It is therefore suggested that the activities
of the killer whale be thoroughly investigated
in its relation to the fur-seal herd. To do so,
will require the services of a well-equipped
vessel. It should be provided with a whale gun
and a man to shoot it, because some of the
animals would have to be killed.
The stomachs of the killers taken should of
course be examined. It may be asked why the
preliminary work can not be done by the shore
whaling stations, but it so happens that almost
every cetacean known is commercially valuable
except the killer. From the diminutive por-
poise to the huge sulphurbottom all are taken
but the orea, and it is left entirely alone.
Therefore, the fur-seal question can not be
studied on shore, where whales are utilized
commercially without special arrangements
being made for the capture of the killers.
If the killer be found the great destroyer
of fur seals which is suspected, then methods
for its destruction should be devised. In lieu
of submarines, it might be made the object of
target practice of navy gunners. Or a bounty
might be offered, so as to make them commer-
cially profitable for whalers to handle. Or
what is probably best of all such suggestions,
fully equip whaling vessels to scour the seas,
just as sheep men of the west keep coyote
hunters constantly on duty.

LOSS FROM ANIMAL DISEASES
Tue Advisory Committee, appointed by the
British Development Commission in 1920, has
issued its report on the facilities now available
for the scientific study of the diseases of ani-
mals, and improvements recommended. Sir
David Prain was chairman of the committee.
According to an abstract in the London
Times, the present value of cattle, sheep, and
pigs in the United Kingdom is estimated, the
report states, at between four and five million
pounds. The Scottish Animal Diseases Re-
SCIENCE
507
search Association estimates the annual loss
from disease in Scotland at close on £1,000,000,
and the committee thinks that the loss in
England and Wales must be four times the loss
in Seotland. The facilities for research at the
five veterinary colleges in the United Kingdom
and Ireland “constitute a national disgrace.”
The sum allocated to veterinary research is
“trifling in comparison with the sums set aside
for medical, agricultural, and fishery research.”
There are certain existing facilities at univer-
sities, medical schools, the Brown Institution,
and attached to the English and Irish Depart-
ments of Agriculture and to the Royal Army
Veterinary Corps. In South Africa there is
a model organization for the study of animal
diseases, £123,447 having been spent during the
year 1920-21 on veterinary education and re-
search. In India immense opportunities are
almost wholly neglected. Leaving out of ac-
count the work in South Africa, the state of
research into animal diseases within the empire
is at present lamentable.
The committee advocates (with reservations
by Sir Walter Fletcher) increased salaries to
workers of proved capacity at Camden Town,
and a capital grant for new laboratories there.
It suggests that facilities for research should be
placed at the disposal of the Royal Army Vet-
erinary Corps, and that a sum should be set
aside annually by the commissioners for spe-
cial researches into animal diseases.
With regard to the training of investigators,
it anticipates that a large proportion will come
from the veterinary profession. It is against
the increase in the number of universities with
veterinary faculties, but wishes more money to
be given to the existing veterinary colleges. It
proposes that the Development Commission
should appoint a diseases of animals research
committee, the majority of whom should be
men of science. To this new body all applica-
tions for grants from the development fund for
research into the diseases of animals should be
referred.
THE CALIFORNIA STATE FISHERIES
LABORATORY
Tue State of California, through its Fish
and Game Commission, has constructed a lab-
oratory in East San Pedro, at Los Angeles
508
Harbor, for the study of the biology of the
fishes utilized in the now very large sardine
and tuna canning industries. The state govern-
ment has found that such studies are an 1m-
perative necessity in the exercise of its legal
control over the fisheries. They are necessary,
not merely for the determination of biological
facts bearing directly upon methods of con-
servation, but also for the interpretation of
the statistics which are now collected by the
state for the purpose of observing the condi-
tion of the fisheries. The statistical system
used is unique, and has proved its independence
of the errors usually introduced by statistics
gathered by personal: inquiry, but the perfec-
tion of the data thus gathered does not elim-
inate, but rather enlarges the importance of
biological knowledge and hence of laboratory
work.
The building is of reinforced concrete, two
stories in height, and of modified Spanish
architecture with red tile roof. There are suf-
ficient accommodations for from six to ten re-
search workers in the three laboratories and
work room. A large library room, a file room,
a dark room and store room are also provided.
It is hoped to collect a library upon fishery
subjects which will be very complete, and to
that end a number of the important periodicals
in the field have been purchased in their en-
tirety. However, aside from the publications
of the International Council for the Investiga-
tion of the Sea, there are not a great many
such periodicals, and the real sparseness of our
knowledge of the commercial fishes is empha-
sized by their lack.
The permanence of the laboratory is assured
by the existence of a law specifying the collec-
tion of the statisties and the biological inves-
tigations necessary. It is felt that it will be
very difficult for reactionary interests to repeal
the law, or to attack the funds collected by
special taxes for the maintenance of the work.
Dependence upon appropriations made from
year to year has proved disastrous in the case
of the federal government and in those of a
number of states, and it is to be hoped that
such a system as is in existence in California
will remain independent of appropriations.
The biological problems which face the

fishery expert are wide in scope and will inev-
itably interest the ecologist and the systematist.
For their solution vast quantities of materials
are available in the canneries and fish markets,
while the detailed records of the catch which
are gathered provide a basis for a real science
of vital statistics of the fisheries. Men inter-
ested along such lines will be cordially wel-
comed in the new laboratory, in so far as its
accommodations are adequate.

MATHEMATICAL PUBLICATIONS
THE Bulletin of the American Mathematical
Society contains several notes concerning math-
ematical publications from which we quote.
The council of the society has received an
offer from an anonymous donor to pay the
cost, up to $4,000, of an extra volume of the
Transactions of the society, to be brought out
promptly. This extra volume will be sent
without charge to all subscribers and exchanges
now. on the list.
Mrs. Mary Hegeler Carus, as trustee for the
Edward C. Hegeler Trust Fund, has given to
the Mathematical Association of America the
sum of $1,200 annually for five years for the
purpose of publishing a series of monographs
whose purpose should be to popularize mathe-
matics by making accessible at nominal cost
the best thoughts and keenest researches in this
field set forth in expository form comprehensi-
ble to teachers and students of mathematics and
to other readers of mathematical intelligence.
The deed of gift includes the promise to capi-
talize this annual income by a permanent en-
dowment fund if at the end of five years the
project shall have proved successful.
The members of the division of mathematics
of Harvard University have constituted them-
selves an informal committee to solicit contribu-
tions to relieve the present financial need of
the Jahrbuch iiber die Fortschritte der Mathe-
matik. The deficit for the coming fiscal year
will amount to about $1,000. The editor, Pro-
fessor L. Lichtenstein, has appealed for aid.

trian Science and Art, which last year appro-
priated 20,500 marks for the Jahrbuch, con-
templates the continuance of its support, sub-

On the occasion of the sixtieth birthday of
Professor David Hilbert, of the University of
Goettingen, his friends, colleagues, and former
students presented to him an address, an album
of photographs, and a memorial volume of
mathematical papers. Among those who joined
in these remembrances were over sixty-five
American friends and former students. The
celebration was directed by a committee con-
sisting of Professors O. Blumenthal (chair-
man), R. Courant, G. Hamel, E. Hecke, A.
Schonflies, and (for America) EK. R. Hedrick.
The mathematical papers of. the memorial vol-
ume will appear separately either in the Math-
ematische Annalen or in the
Zettschrift.
The preparation of the complete edition of
the works of Sophus Lie, undertaken in 1912
by Teubner, but suspended because of the
greatly increased cost of printing, will be re-
sumed with the financial support of the Nor-
wegian Mathematical Society. The title of the
edition will read: Sophus Lie, Gesammelte

THE ELIAKIM HASTINGS MOORE FUND
a
On the occasion of the twenty-fifth anniver-
sary meeting of the Chicago Section of the
American Mathematical Society, held in Chi-
cago on April 14 and 15, 1922, the following
resolutions, with the names of 174 contributors,
were presented to Professor E. H. Moore in a
beautifully bound and illuminated manuscript:
Conscious of the great influence which you have
exercised upon the development of mathematical
science throughout this country, particularly in
the Middle West during the last twenty-five years,
Admiring the outstanding qualities of your re-
searches in various fields of mathematics,
Grateful for the inspiration and the encour-
agement which you have given to those who have
come to the University of Chicago to study mathe-
matics,
Recognizing the large contribution which you
have made to the creation and the growth of the
Chicago Section of the American Mathematical
Society,
Deeply appreciative of the friendship which,
during many years, you have shown toward those
who have had the good fortune to know you,
The undersigned members of the American
Mathematical Society, formerly students of math-
ematices at the University of Chicago, or members
of long standing in the Chicago Section, have
wished to use the opportunity afforded by the
twenty-fifth anniversary meeting of the Chicago
Section to present to you a testimonial, which is
intended to link your name in the years to come
with the development of mathematics in this
country.
To this end they have contributed to a fund
which is to be offered for trusteeship to the
American Mathematical Society upon the follow-
ing conditions:
1. The fund is to be known as the Eliakim
Hastings Moore Fund.
2. The interest on the fund is to be used at the
discretion of the council of the society, and upon
the recommendation of a committee appointed
from time to time for this purpose, in furtherance
of such mathematical interests as
(a) The publication of important mathematical
books and memoirs.
(b) The award of prizes for important con-
tributions to mathematics;
it being further recommended that during the
next ten years preference be given to the former,
and that publication of Professor E. H. Moore’s
SCIENCE
[Vou. LV, No. 1428
researches in general analysis or other fields shall
have precedence over all other claims.
3. The fund is to be kept intact by the Amer-
ican Mathematical Society except in so far as it
is used to aid in the publication of Professor
Moore’s researches. For this special purpose a
part of the principal, not exceeding one third,
may be used provided the interest on the remain-
der be allowed to accumulate until the fund has
been restored to its original value.
The trusteeship of the HEliakim Hastings
Moore Fund was accepted by the council of
the American Mathematical Society at its meet-
ing on April 15. The society intends to keep
the fund, which now amounts to nearly $2,000,
open for further contributions so that it may
become the nucleus for a much larger fund at
the disposal of the American Mathematical
Society for aid in the publication of important
mathematical work. Contributions may be sent
to the secretary of the ‘society, Professor
R. G. D. Richardson, Brown University, Provi-
dence, Rhode Island.

DISCUSSION AND CORRESPOND-
ENCE
DID HUMPHRY DAVY MELT ICE BY
RUBBING TWO PIECES TOGETHER
UNDER THE RECEIVER OF
AN AIR PUMP ?
Ir is commonly stated that Humphry Davy
melted two pieces of ice by rubbing them to-
gether under the exhausted receiver of an air
pump, and thus showed conclusively that heat
is not a material substance. In books which
I happen to have at hand I find twelve different
authors stating that Davy melted two pieces
of ice by rubbing them together in a vacuum,
and four of them stating in addition that the
two pieces of ice were rubbed together by
clockwork. In looking to see what Davy him-
self said about this experiment I have, to my
surprise, failed to find any evidence that he
ever performed just this experiment.
Of the authors whom I consulted, four give
references. Two refer to the Collected Works
of Sir Humphry Davy, vol. 2, p. 11. The
other two refer to Davy’s Elements of Chem-
ical Philosophy. In the Elements of Chem-
ical Philosophy, reprinted as Volume 4 of the
Collected Works, I have not found any state-
ment about the melting of ice by friction. In
the first paper in Volume 2 of the Collected
Works Davy describes twenty-two experiments
and makes comments on them. 5
In Experiment 2, p. 11, he deseribes an ex-
periment in which “by a peculiar mechanism”
he caused two blocks of ice to rub together.
“They were almost entirely converted into
water.” In the description of this experiment
nothing is said about any air pump.
The description of the third experiment is
not entirely clear. Davy says, “I procured a
piece of clock-work so constructed as to be
set to work in the exhausted receiver; one of
the external wheels of this machine came in
contact with a thin metallic plate. A con-
siderable degree of sensible heat was produced
by friction between the wheel and plate when
the machine worked uninsulated from bodies
capable of communicating heat. I next pro-
SCIENCE
[Vou. LV, No. 1428
cured a small piece of ice; round the superior
edge of this a small canal was made and filled
with water. The machine was placed on the
ice, but not in contact with the water. Thus
disposed, the whole was placed under the re-
ceiver. The receiver was now ex-
hausted. The machine was now set
to work. The wax rapidly melting, proved
the increase of temperature.”
From this description it seems that the clock-
work was not a mechanism for rubbing two
pieces of ice together, but was used to pro-
duce friction between two metals, and that
the heat developed by this friction caused the
melting of some wax.
Any clockwork which Davy might have
placed inside of the receiver would probably
not have been sufficiently powerful to melt
ice rapidly by rubbing it on ice. J have
wondered if some author did not read tthe sec-
ond experiment, glance at the third, and see-
ing the words clockwork, exhausted receiver,
ice conclude that two blocks of ice were rubbed
together by clockwork under the exhausted re-
ceiver. If so, this is an interesting illustra-
tion of the ease with which a misstatement may
pass from one author to another. If there is
evidence that Davy did melt two blocks of
ice by causing clockwork to rub them together
under the receiver of an air pump I hope some
one will adduce it.

THE TEACHING OF EVOLUTION IN THE
BAPTIST INSTITUTIONS OF TEXAS
THE teaching of evolution in the Baptist
denominational schools in Texas is being in-
vestigated as heretical. The denomination is
strong in membership and maintains about 15
colleges and seminaries in the state, the chief
ct which is Baylor University at Waco. It
appears that the trouble arose as the result of
the publication in 1920, by the Baylor Univer-
sity Press itself, of an ‘Introduction to the
Principles of Sociology,” by Grove Samuel
Dow, Professor of Sociology in Baylor Univer-
sity. The book is based upon the theory of
evolution wherever it touches upon the bio-
logical aspects of sociology, although the term
biological evolution is scarcely or not at all
used in the text. At a recent conference of
representatives of the Baptists of all parts of
the state, such teachings were pronounced
heresy, and a sweeping investigation is being
made of all of the Baptist schools of the state
to determine how much “heresy” is being
taught. Professor Dow has resigned his posi-
tion.
A somewhat related situation has existed at
Southern Methodist University, Dallas, where
the teaching of Dr. John A. Rice, Professor of
Old Testament Interpretation, has created the
severe opposition of a large part of his church.
Dr. Rice’s book, “The Old Testament in the
Life of Today,” looks upon the Old Testament
as a series of independent historical papers,
each subject to its own interpretation. Many
are considered as having been revised by sev-
eral authors before they have reached their
present form. Each is regarded as a literary
production, subject to all of the rules of liter-
ary interpretation; this introduces a personal
factor into any understanding of the Old
Testament, and completely does away with
literal interpretations. Dr. Rice has also left
SCIENCE
515
his position, to become pastor of a Methodist
church in another state.

THE METRIC CAMPAIGN
Mr. Hatusry’s recent letter in Sctence is of
interest in view of the hearings that have been
held during the past few months on the Britten-
Ladd Bill. It was made clear in these hearings
that wire, for instance, is readily defined as a
2 millimeter wire (2 mm in diameter) or, by a
less convenient method, as a wire 0.079 inch in
diameter. An inferior method is to refer to
such a wire as a No. 46 Stubs’ wire (2.01 mm
or 0.079 inch) or a No. 14 Birmingham
(Stubs’) wire (2.11 mm or 0.083 inch). There
are at least three other gages that have been
used to a greater or less extent. It was shown
in the metric hearings that if this convenient
metric method continued to prevail, certain
gage manufacturers would lose the advertising
value connected with the use of their gages.
It furthermore developed that it was a gage
manufacturer who had organized what opposi-
tion he could in order to fight the metrie sys-
tem, had contributed $1,000 from his firm and
had brought about the employment of Mr.
Halsey in his metric fight. Mr. Halsey had
profited by his anti-metriec efforts in the past.
His own words in this controversy were “We
have killed the metric system before and we
will kill it again.” We have no objection to
Mr. Halsey’s attempted slaughter of the metric
system. Readers of Sctencr, however, may be
unaccustomed to his method of argument. In
his recent letter, for instance, he endeavors to
make it appear that Professor E. C. Bingham
of Lafayette College is “naive” and ignorant
regarding weights and measures, and that there-
fore he should not be encouraged in the suc-
cessful campaign to secure the use of metrie
weights and measures throughout the industry
in which he is an expert. Professor Bingham’s
many friends and acquaintances do not need to
be told that he is unusually well informed and
proficient in his work.
Mr. Halsey’s use of the title “Commissioner”
is also of interest. This has led a few people to
believe for a time that Mr. Halsey in some
516
way represented a federal, state or municipal
organization.
Mr. Halsey refers to a report issued in
October, 1921, as confirmation of all his con-
tentions. It is amusing to find that this report
was drawn up under the guidance of a com-
mittee of five men: the gage manufacturer re-
ferred to above, two others associated with him
in his fight to kill the metric system, and an
impotent minority of two good metric advo-
cates.
However, the use of metric weights and
measures, legal for all transactions in the
United States since July 28, 1866, is above
personalities. As a nation we find ourselves
to-day endeavoring to bring about mutual
understanding and world-wide trade. At least
46 countries have officially adopted the metric
system for general use. Partly through the ex-
cellent work of the Decimal Association of
London, England has already left America be-
hind in the use of metric weights and measures.
The hearings are over on the Britten-Ladd
Bill. The campaign to put this bill, or a modi-
fied form of it, through Congress is before our
association. At the same time we are co-
operating with the Toronto and other sections
of the American Metric Association, and an
ever increasing number of men and women in
North America are using metric weights and
measures. We ask for the cooperation of all
in the United States and Canada.

the scientific works of the great anatomist and
anthropologist who died in the summer of 1919.
This posthumous volume has been edited and
compiled at the request of Madame Retzius by
Professor Carl Furst, of the University of
Lund. Professor Furst is the oldest living

friend and colleague of Retzius, and was well
equipped, both by virtue of long acquaintance
and collaboration with the author, and by
familiarity with his work, to edit for publica-
tion the series of technical papers which ccm-
prise the volume. These papers are seven in
number, and are accompanied by twenty-one
beautiful plates of folio size.
The first contribution, under the title,
“Weitere Beitrage zur Kenntnis von dem Bau
und der Anordnung des Ependyms und der
simtlichen Neuroglia, besonders bei den niede-
ren Vertebraten” (Taf. I-X VI), describes the
neuroglia and ependyma of various vertebrates
in four sections, viz.: A. Amphioxus; B.
Myxine; C. Petromyzon; and D. Selachians,
Teleosts, Amphibia, Birds and Mammals. The
text of section D has been inserted by the editor
from a translation into German of an article
originally published elsewhere by Retzius in
Swedish. The editor states: “Wir bekommen
dadurech von Retzius selbst eine Erklirung
einiger wichtiger, hier mitgeteilten Figuren.
Gustaf Retzius hat mehrmals friihere Arbeiten,
die in schwedischer Sprache herausgegeben
waren, spiter in Biol. Unter. in deutscher
Ubersetzung aufgenommen. Wenn ich diese
Abhandlung aus der Miillerschen Festschrift
einsetze lasse ich doch grossteils die historische
Hinleitung der Abhandlung aus. Der Inhalt
dieses Historik ist n&émlich in den hier oben
mitgeteilten Abhandlung ausfiihrlichen mit-
geteilt.”
The second paper, “Hinige Beitrige zur
Kenntnis der Structur der Ependym— und
Nervenzellen im Riickenmark der Cyclostomen”
(Taf. XVII, Fig. 1-24), deseribes a type of
cell among the ependyma cells of the spinal
cord of cyclostomes which has been ealled
“inneren Sinneszellen’”’ by several investigators,
but which Retzius concludes are modified
ependyma cells. The second part of this article
considers the fibrillar structure of nerve cells
of the spinal cord in this lowly group of verte-
brates.
Nine of the folio pages and one plate (Taf.
XVIII) describe certain phases of the struc-
ture of the lens of the eye, under the title
“Zur Kenntnis des Baus des Glaskorpers im
Auge des Menschen.”
May 12, 1922]
In the fourth and fifth articles (Taf. XIX-
XXI) the author continues his already exten-
sive studies on the spermatozoa of various
animal groups, under the titles “Die Spermien
der Cyclostomen” and “Noch einige Beitrage
zur Kenntnis der Spermien bei den Affen,”
respectively.
“Die Gehirne der Affengattungen Cebus und
Ateles” is without figures. It consists of some
notes which supplement the author’s earlier
work, “Das Affenhirn in bildricher Darstel-
lung,” in which figures. of these brains are
found.
The final contribution “Die Verbindungen
zwischen dem Sarcolemma und den Grund-
membranen der Muskelfibrillen in bildricher
Darstellung” (Taf. XVII, Fig. 25-27) is made
up of three figures which represent the striated
muscle of salamander larve, showing the finer
structure of the muscle fibers and the relation
of the ground membrane to the myofibrille and
to the sarcolemma. Apparently a paper on
this subject was contemplated by Retzius, but
the text was not written. The editor refrains
from supplying it, stating “Die Bilder demon-
strieren selbst so gut diese Verhiiltnisse dass
eine eingehende Erklirung nicht notig ist.
Prinzipiell will ich hier nicht versuchen, Worte,
die Retzius nicht selbst niedergeschrieben hat,
ihm in den Mund zu legen.” This statement
admirably summarizes the attitude of the editor
toward the contents of the entire volume.
The volume closes with an excellent table of
contents of the two series of the Biologische
Untersuchungen, namely, the two volumes
which appeared in 1881 and 1882, and the
nineteen volumes of the Neue Folge. Follow-
ing this is a bibliography of the scientific works
of Retzius, arranged by subjects. This bibliog-
raphy consists of 333 titles.
Tt is fitting that the dedicatory page which
in the preceding volumes has borne the names
of so many distinguished anatomists should
bear in the last volume the inscription by the
widow of the author:

To the sympathetic cooperation of his wife
is due in no small measure, together with his
own untiring zeal, the unique monument which

numerous other papers and monographs which
bear his name.

POLYPLOIDY, POLYSPORY, AND HYBRIDISM
IN THE ANGIOSPERMS
For some time investigations have been car-
ried on in these laboratories on the subject of
polyploidy in relation to polyspory and hy-
bridism. The material used consists of both
Dicotyledons and Monocotyledons, and repre-
sents either known hybrids or species belonging
to genera or groups in which a great deal of
natural hybridism is suspected. The conclusion
has been reached that polyploidy is a common
result of incompatible species crosses. The
normal gametophytic number of chromosomes
becomes multiplied by three, four, ete. as
a consequence of such inharmonious crosses,
in various degrees of complexity. A frequent,
although not invariable accompanying feature
of polyploidy is the phenomenon of polyspory.
As is well known, the normal divisions tak-
ing place in the spore-mother cells of the Angio-
sperms, lead to the formation of four spores.
Some of the members of the normal tetrad of
spores may exceptionally abort, as for example,
in the microspores of certain sedges. This
condition of abortion is the normal one in the
formation of megaspores. In the case of poly-
spory the first division of the spore-mother
cell leads to the formation of more than the
two normal daughter nuclei. Two larger nu-
clei are generally formed by the union of cer-
tain of the chromosomes which undergo sepa-
ration into daughter groups at a moment pre-
ceding that in which the remaining chromo-
somes pass into the metakinetic phase. The
later dividing chromosomes, in separating
tardily into daughter groups are ordinarily
518
fewer in number than are those concerned in
the formation of the two main daughter nuclei.
The nuclear bodies formed by their fusion lie
ultimately lateral to the spindle instead of ter-
minal as in the case of the larger nuclei, and
are of strikingly small size. There may be as
many as four of the small nuclei at the end
of the first division of the pollen mother-cells.
When the second division takes place a further
formation of normal large nuclei (aggregating
four in number), and of abnormal small nuclei
more numerous than are the large nuclei re-
sults. The large nuclei give rise usually to
normal pollen grains but some or all of the
grains resulting from them may abort. The
small nuclei derived from the late-dividing and
small groups of chromosomes give rise appar-
ently always to abortive grains. A number
of publications from this laboratory? have em-
phasized the importance of pollen sterility as
a reliable morphological criterion of previous
heterozygosis or genetical impurity.
Special attention has been devoted to abort-
ive pollen as evidence of hybridism in the case
of the Onagracee and Rosacee, but it is like-
wise found in many other groups. It is in-
teresting to note that Tackholm in Sweden?
and Blackburn and Harrison* in England, have

[Vou. LV, No. 1428
recently pointed out the coincidence of hybrid-
ism and polyspory in the genus Rosa. Our
investigations have made this condition clear
for a considerable range of Dicotyledons and
Monocotyledons. Tackholm has asserted on the
basis of his extensive studies that all the roses
belonging to the Canina section of the genus
Rosa, in other words, the roses of Europe, of
western Asia, and of northern Africa, are
throughout hybrids probably thousands of
years old and reproducing by apparently nor-
mal seeds, which are nevertheless formed
“apomictically” and without the intervention
of a sexual act. Obviously such seeds will
“eome true’ as universally as do grafts or
vegetative multiplications of any kind and for
the same reason because they represent only
subdivisions of the vegetative body.
Polyspory appears as a consequence of our
investigations, which will be published in full
at a later stage, as a frequent although not
invariable result of hybridization of species
(that is, of species crosses), and constitutes
one more valuable structural or morphological
criterion of heterozygosis. It frequently ac-
companies polyploidy and the manifestations
of the so-called “lethal factor” in marked re-
productive sterility in either known or sus-
pected hybrids between species of the higher
plants.
We have now the following morphological
criteria of genetical impurity or heterozygosis
in plants, namely, reproductive sterility (most
easily observed in the case of the microspores
or pollen), gigantism, variability (mutability),
polyploidy and polyspory. Not all of these
may occur in any given ease, but the coin-
cidence of any considerable number of these
features should be regarded as supplying
strong evidence of previous crossing of more
or less incompatible species or varieties.

THE REACTION OF DROSOPHILA TO
ULTRAVIOLET
AurHouGH there is no unanimity of opinion
as to the ability of insects to distinguish colors
in the sense that humans do, it is fairly well
established that the tendency is for them to
react most strongly to wave-lengths in the
violet end of our visible spectrum. This sug-
gests the possibility that insects may be sensi-
tive to ultraviolet, to which the human eye is
relatively insensitive except indirectly by
fluorescence in the cornea. The possibility is
of interest in connection with the general prob-
lem of the biological relations between flowers
and insects, for flowers may be “ultraviolet” as
well as red, yellow, and so on. A committee of
the National Research Council is planning to
do field-work on this problem during the coming
summer and it was thought that the following
experiments might give useful preliminary
information. They were made with the as-
sistance of Mr. Ware Cattell.
Drosophila melanogaster exhibits a strong
tendency to move toward the source of light.
A large number of these flies were placed in
a test tube about 30 em. long and 2 em. diam-
eter, the end being closed with a plug of cotton.
A strip of black paper was rolled around the
tube to protect from stray light. By shpping
the paper down from the end of the tube the
flies could be “concentrated” next to the cotton
plug. The paper was then replaced and the
tube placed horizontal with its rounded end
toward the spark from a 200 watt General
Electric ultraviolet generator. Between the
generator and the tube were placed four thick-
nesses, totaling about 1 em., of Corning ultra-
violet glass, number G586A (old number
G55A62). After an exposure of 15 seconds
the flies were found to have congregated in the
end of the tube next to the source, showing
that they were strongly attracted by the ultra-
violet generated by the spark and transmitted
by the special glass.
The transmission of this glass has been
measured by the Bureau of Standards (Tech-
nological paper Number 148: “The Ultraviolet
and Visible Transmission of Various Colored
Glasses”). A thickness of one centimeter
transmits about 70 per cent. of light in the
SCIENCE
519
neighborhood of 0.36; about 25 per cent. near
.34; but only 5 per cent. at 0.40. This glass
transmits also a small amount of red. The
flies, however, did not react when we used a
red glass which transmitted far more red than
Gd86A.
To make a more accurate test, a quartz spec-
trograph was used to disperse the light from
the ultraviolet generator. Light of wave-length
greater than .39 was excluded by a strip of
black paper in the focal plane. As before, the
flies showed a very marked reaction when the
horizontal test was “pointed” toward the ultra-
violet source.
This last result was, however, rendered some-
what doubtful by the fact that the quartz
lenses and the dispersing system scattered a
small amount of blue and violet light. This
seattered light was entirely eliminated, at least
so far as human vision is concerned, by inter-
posing a single thickness, 2.5 millimeters, of
G586A in the path of the light. But even then
the flies showed a marked reaction. The con-
clusion is that Drosophila melanogaster 1s more
sensitive to ultraviolet light than is the human
eye.
The question may still be raised that these
phototropie reactions of Drosophila are due to
fluorescence of eye media, similar to that expe-
rienced by the human eye when exposed to
ultraviolet light. All that can be said at
present in this connection is that the intensity
was so low that we did not experience the visual
sensation characteristic of such fluorescence,
but the flies reacted promptly and definitely.

tributing to the success of the meeting was the
untiring work of the local committees and the
cordiality of the members of the University of
Toronto and the Royal Canadian Society. The
international character of the Toronto meeting
was noted by the presence of more Canadians
than usual and by the distinguished visitors
from abroad.

No separate session of Section K was ar-
ranged for the Toronto meeting on account of
the recent death of the secretary, Dr. Loomis.
A joint session of the section was held, how-
ever, with Section Q (Education) on Friday
afternoon, December 30, 1921. At this meeting
Dr. Frederick L. Hoffman, the recently elected
secretary of the section, read an extended ad-
dress on “The Organization of Knowledge,”
subsequently reprinted in Scimnce of March
10 and March 17, 1922. Dr. Henry S. Graves
of Washington was elected vice-president for
Section K for 1922. Dr. Frederick L. Hoff-
man, dean of the Babson Institute, Wellesley
Hills, Massachusetts, was elected secretary; his
term of office will expire January 1, 1925. An
understanding was arrived at under which the
section, during the current year, will concen-
trate its efforts especially upon conservation
problems. The American Metric Association,
which is associated with Section K, held ses-
sions on Friday morning and Friday afternoon,
December 29. During this session, nine papers
were read and much discussion was had sug-
gestive of the slow but gratifying progress of
the metric movement. On Friday evening the
Metric Association held its annual dinner, par-
ticipated in by a small but thoroughly interest-
ed group of members.

SECTION N—MEDICAL SCIENCES
Section N (Medical Sciences) held a sym-
posium on the Health and Development of the
Child. Professor A. B. MacCallum, of MeGill
University, presided. Dr. Joseph Erlanger of
Washington University read his vice-presiden-
tial address on “The past and the future of
the medical sciences,” already published in
Science, Vol. 55, page 135, February 10, 1922.
The following papers were read:
Hereditary factor in development: C. B. DAvVEN-

Port, Cold Spring Harbor, L. I.
The metabolism of children in health and dis-
ease: Haronp Baiuey, Cornell Medical School,

The mental hygiene of children: C. N. Hincxs,
Canadian National Committee for Mental Hy-
giene.
The meeting took place in the Academy of
Medicine, Toronto, which was crowded far be-
yond capacity. Throughout the symposium,
there was a most interesting discussion of the
papers.
The experience of the sectional committee
during the last seven years has convinced it
that its former policy, to have a discussion of
a definite topic with invited papers, was timely,
instructive, and interesting to the members of
the association, to those working in medical
sciences, and to the community.
There was, however, a growing feeling that
the section should undertake to reach more
effectively the investigators in the various fields
allied to the medical sciences. It was felt that
these workers require more than ever the stim-
ulation that comes from discussion of papers
by the workers in allied fields.
An informal meeting was called on Decem-
ber 28, at which representatives of medical
workers, parasitologists, economic entomolo-
gists and biologists were present. The central
question was how real and widespread was the
need for such closer coordination of allied
workers; how this coordination could be met
without the formation of new groups.
There was a surprising unanimity of opinion
of the desirability and the necessity of such
closer coordination for mutual information and
stimulation. It was decided to form no new
groups. It was decided that the secretary of
Section N, Medical Sciences, in consultation
with the secretaries of the parasitologists, the
two entomological societies and others, was to
arrange a program in such a manner that it
might be possible for the members of these re-
lated societies to attend a meeting held under
SCIENCE
[Vou. LV, No. 1428
the auspices of Section N (Medical Sciences)
with the minimum of conflicts; that Section N
(Medical Sciences) should arrange an invita-
tion program by representatives of the en-
tomologists, the parasitologists, and medical
workers, on topics of mutual interest. The
opinion was definitely expressed that the spe-
cialists have so far transgressed the narrow
limits of their respective fields that there is an
increasing need of information and stimulation
and exchange of views on the part of those
working in allied fields; and finally, that the
meeting of Section N (Medical Sciences) should
be devoted primarily to the coordination of
such allied workers.
This is a distinct departure from the policy
of Section N in the past. If it should appear
desirable to add to such a program, an addi-
tional program in the interest of the larger
membership of the association, such a program
shall be arranged.
It was also the consensus of opinion that
once each year Section N (Medical Sciences)
should hold a joint meeting with one of the
national medical organizations or federations,
so as to knit more closely the bonds between
the American Association for the Advancement
of Science and these other organizations. Such
an arrangement already exists between the
Federation of Experimental Biologists and
Section N (Medical Sciences). It was pro-
posed that once in every four years a joint
meeting should be held between Section N
(Medical Sciences) and the Anatomists, the
Public Health Association, and the Bacteriolo-
gists.
Plans are now under way to make these sug-
gestions effective. The secretary will appre-
ciate suggestions and advice. This is no place
to discuss the vexing problem of the relation
of the sections, such as chemistry and engineer-
ing, and the large national organizations so
loosely affiliated with the association, but the
problem seems to be the same in all these
instances, and any assistance to this complex
problem will be appreciated by these and other
groups who must plan the meetings for the
coming years.

with easy interchangeability;
2. Provides a powerful light source for oil immersion work, as well as dark-
field microscopy;
3. Requires minimum time for adjustment ready for work;
4. Bulb used is a stock electric lamp, obtainable anywhere;
5. Makes a substage lamp when no condenser is on the microscope.
For oil immersion work, this lamp is attached to the Abbe
condenser, whether new or already in use on the microscope. The
bulb, which ean be easily centered, by its position is always in the
focus of a strong curve condenser, so that parallel light of even
intensity is delivered. A special Blue Glass Dise is supplied for
use in moderating the illumination when it is too. bright.

CLINOSTAT
Universal-Motor Driven
WE HAVE developed an instrument which has many special advantages over the previ-
ous types and embodies a rigidity and durability that cannot be secured from a clock mech-
anism instrument.
This outfit consists of two essential parts. First, what is designated as the Master Clino-
stat, and, second, what may be designated as the Secondary Clinostat.
The Master Clinostat consists of suitable reducing gears arranged so as to reduce motor
speed of about 500 R.P.M. down to approximately one revolution in about 15 minutes. Any
higher speed may be obtained. This speed is given to the shaft bearing the plate and suitable
adjustable clamps hold a flower pot of 3 or 4 inch size. The supporting plate may be adjusted
so that the plant may be rotated in either a vertical or horizontal direction, or in any intermedi-
ary direction. There is attached as a driving means a flexible shaft, which is arranged on one
end so that it may be inserted in the clutch of the motor rotator. It may also be attached to
any other rotator or to any motor.
The Secondary Clinostat consists of a suitable base and reducing gear, and supporting
plates with clamp similar to the Master Clinostat, and the two shafts engage, and thus the
Master Clinostat drives the Secondary Clinostat. Any number of these Secondary Clinostats
may be thus connected and any number of experiments carried on at the same time. Some of
these may be adjusted for rotation in a horizontal direction and some in a vertical direction.
The method of engaging the two shafts is such that there is no binding and it is not necessary
that they be exactly in alignment.
The clamps for holding the flowerpots are very easily adjusted and will carry any size plant
that may be contained in a 4 inch flowerpot.
The adjusting mechanism in changing from vertical to horizontal rotation is done by simply
operating a lever and is very easily operated.
Each of these instruments is mounted on aheavy iron base, handsomely japanned, and all
parts are finished in black with nickel plated trimmings. It makes a very handsome appearance
and is an instrument which will be found a pleasure to work with and, at the same time, its
rigid construction insures it durability and guarantees the continued service that may be ex-
pected from this instrument.
Cat. No. 8349 Master Clinostat, as described above. Complete with flexible shaft, three clamps, without
flowerpot.

SCIENCE OR ATHLETICS?!
THERE has never been a period in the history
of science when educational questions relating
to its advancement have appeared to possess
such interest or when discussions have dealt so
freely with the shortcomings of the educational
system in its relation to the training of students
of science. On the one hand is an intensely
practical industrial world, insisting upon a
close scrutiny of the content of the college
courses and of the methods used in administer-
ing them,—from the standpoint of their imme-
diate practical application to industrial prob-
lems and from this standpoint alone,—while
on the other is the world of the college teacher,
seeing or thinking it sees much in science and
in the teaching of science that is not to be
judged in this limited fashion. We are turned
this way and that in the attempt to see all
viewpoints and to make use of all constructive
advice. We desire that our students shall be
as well equipped as possible in whatever of
science it is possible to teach them in the time
that is allotted to us, so that when they leave
us to take up their share in the general ad-
vancement of science they shall be able to
acquit themselves honorably and to add what-
ever they may in the application of science to
the problem of increasing the happiness and
comfort of humanity.
Chemical education has not been spared in
this discussion. Rather has it been the center
of the major part of the discussion, for in no
other single science has there been so spectacu-
lar and so amazing a success in research and
in the tangible results of the application of
research to practical problems. It has there-
fore come about that there is no other science
in which it is more important that the college

tion at the Birmingham meeting, April, 1922.

and the university shall succeed in evolving
proper and effective methods for the scientific
training of the youth of the land, since it is
upon the mental equipment and the mental
habits of our present and future students that
the future of the science depends.
I propose to discuss certain phases of this
subject from the standpoint of the college
teacher. We respect the viewpoint of those
practical men who, like Mr. Edison, feel that
about the only trouble with the college gradu-
ate is that he knows nothing and is good for
nothing, also of those other, perhaps broader
minded, technical men who recognize the value
of college training but who believe that the
teachings of the class room and student labora-
tory are too far removed from the problems and
methods of industrial applications. We also
realize that some of our eminent research
chemists are insisting that the college and the
university should busy themselves with funda-
mental principles and that they should keep
hands off the plant processes, while others are
equally emphatic in the view that research
should be more along practical lines. \
Without, at present, presuming to argue any
of these questions and respecting the integrity
of all who offer them, we respectfully submit
that in the effort of the college teacher to ad-
minister courses of training, either routine or
research in purpose, there are certain factors
that constantly baffle and discourage, that these
factors are to a considerable extent under the
control of some of those who complain of our
shortcomings and even that the continuance of
such conditions is directly traceable to the
activities of some of the critics. This may
seem to be a statement that requires justifica-
tion.
I take it that every one will agree that the
study of chemistry as a preparation for suc-
cessful research or for work in the application
of chemistry to practical problems is an enter-
prise that calls for the concentration and
supreme effort of high grade intelligence. Any
person who expects to devote merely left-over
energy and surplus thought to superficial
aspects of any science,—and especially of
foreordained to a career of
The stu-
chemistry,—is
attainment that is mediocre or worse.

[Vou. LV, No. 1429
dents of chemistry of past years who consist-
ently followed the practice of “living the life”
in college, making of themselves “all-around
men” by the time-hallowed practice of taking
part in every possible activity on the campus
and off it, except the one for which they paid
their money and for which they sacrificed the
best years of their lives,—these men, with few
exceptions, now make up the army of fillers of
small positions, doers of small things and
thinkers of small thoughts. They have a cer-
tain routine part in the routine affairs of
science but when they are gone their places
will easily be filled by others who have fol-
lowed the same line of reasoning and of con-
duct.
The college teacher who is dull and uninspir-
ing in his contact with students will have a
class of dull and uninspired students. This,
no matter how well tramed he may be or how
earnestly he may desire to fulfill his mission as
a teacher. But if the teacher is all that we
may desire to see in a teacher :—well grounded
in his subject, of broad vision and purpose,
energetic, inspired and inspiring,—he may fire
his students with boundless zeal for the things
and deeds of science, he may grip their intel-
lects and emotions while in the class room or
laboratory, he may fill them with the highest
kind of resolve for high endeavor, but he ean
not make true students of science of them when
the whole atmopshere of the college is that of
one grand hurly-burly of everything under
heaven except study. Every teacher who hears
this or who reads it knows that, to far too
great an extent, this is the atmosphere of the
modern American college. Some of our atmos-
pheres are better than others,—or we might
even say that some are worse than others. But
when the student goes out from his session
with the best teacher in the best college in the
land he immediately finds himself in the midst
of a multitude of distracting circumstances,
events, activities and enterprises. It ean not
be denied that the effect of this is to lower the
efficiency of the student, to weaken his mental
resolve for high accomplishment and to render
impotent much of the effort that has been ex-
pended by the instructor. It has repeatedly
been emphasized that extra-curricular activi-
May 19, 1922] .
ties play a large part in the development of
character and in the making of men who can
deal with men. I am not denying this. Rather,
I assent to it and give it emphasis. But I add,
also, that the undue multiplication of student
activities and campus side-shows plays an ever
increasing part in the pulling down of the edu-
cational system with which we have labored
so carefully and so painfully, and in the dis-
sipation of the scientifie efforts of those who
should be our best students. Superficial train-
ing is the inevitable result and superficial
training and narrowness of viewpoint are the
blight of our system of scientific education
to-day.
Many of our American colleges make an
advertising point of the large numbers of stu-
dents who flock to their doors, but I believe
that it is no exaggeration to say that if we
could exchange our annual crowds of graduates
in chemistry, immature in intellect, unsettled
in purpose and under-done in real scientific
education as too many of them are, for a small
fraction of this number of young men and
women of good minds, well grounded in funda-
mentals, possessing a broader culture and
accustomed to profound thinking on serious
matters, the world at large and the science of
chemistry would be immeasurably benefited.
That we are, even now, occasionally finding
some of these minds and doing something
toward their proper development is cause for
real rejoicing. That we might find and de-
velop more of them if conditions were changed
is a proposition that will bear examination.
What, then, is to be done about this ques-
tion of the dissipation of the youthful fire of
our students among the hundreds of non-
essentials of college life? Change it, of course,
say our critics. Exactly. And if our Amer-
ican colleges were now, in the truest and most
complete sense of the word, “educational insti-
tutions” this would not, I verily believe, be a
particularly difficult or perplexing undertak-
ing. But, fellow scientists, our American col-
leges are to-day waking into the realization that
they have somehow developed a liason with an
organization that not only is not educational
in its purpose,—it is actually one of the most
insidious destroyers of educational standards

that we have to combat to-day. This organiza-
tion is no other than the modern highly com-
mercialized intercollegiate athletic system,
financed by forces that care nothing for edu-
cation and fostered by extravagantly paid
coaches who trample all of the ideals of educa-
tion under foot in their desire for personal
glory and personal profit.
There is a perfectly legitimate and desirable
field for college athletics. We desire that our
students shall have systematic physical exercise
because this makes for health and contentment
and thus, indirectly, for scholastic success. We
know also that the spirit of competition is an
all-powerful incentive for excellence in any line
of activity and the athletic game is the logical
expression of this. But this idea has become
almost entirely overshadowed through the de-
velopment of a system that places the vast
majority of our students upon the bleachers
and concerns itself with an excessive degree of
specialization with an almost negligible minor-
ity. A friend of ours has tritely stated that
the American people have become afflicted with
a disease which he ealls “bleacheritis.” They
find their highest enjoyment in lounging on the
side lines, entertained by mediocre “movies,”
bad vaudeville, athletic contests or any other
novel spectacle, and they take too little inter-
est in wholesome activity on their own part or
in play for the sake of its effect upon their
minds and bodies. Even the hysteria of the
college “pep session” accomplishes only a tem-
porary rousing from this apathy. The result,
in college life, is the almost absolute failure of
physical education to accomplish any important
part of its mission to keep the bodies of our
students healthy and their minds alert, and to
turn them back into the class room and labora-
tory full of vim and enthusiasm for the most
important work of their education. This can
not fail to work harm to the scholastic success
of the student. That it goes even farther than
this and that it seriously affects the eduea-
tional standards of our colleges is a fact which
we can not safely ignore.
Within the past few months there has been
an unusual amount of discussion of the matter
of professionalism in college athletics. The
colleges have come in for a great deal of eriti-
526
cism and especially in a few instances where
players have been disqualified from intercolle-
giate competition because of having partici-
pated in games of a semi-professional nature,
and where there have been exposés of the
attempts of coaches and others to influence
prospective student athletes by the use of
money. How much may we expect to accom-
plish by disqualifying a few players, here and
there, or by the dismissal of a coach or two
for the breaking of the rules regarding the
payment of money to athletes? I think that
we shall accomplish very little of a remedial
nature by this sort of publicity unless we go
considerably farther. These published cases of
professionalism in students have been largely
technical in their nature and it appears evident
that the students in question do not feel any
consciousness of guilt nor are they regarded
as criminals by their fellows. The general
public probably sees little in all this but a
rather fantastic exhibition of hair-splitting
and quibblng by college folk, who appear to
magnify a purely technical offense into a serious
case of law breaking. It is probably true that
the majority of non-collegiate observers,—or
at least of those who take an interest in ath-
letic affairs,—sympathize with the players who
are detected in what they regard as purely
technical violations of unnecessarily strict tech-
nical rules.
The principal reason for all this is that the
average person does not appreciate the real
evil of professionalism in college athletics. He
sees nothing inherently wrong in playing for
money, any more than in doing any other
legitimate thing for compensation. We have
professional baseball and enormous numbers of
us go to see it and feel that it is perfectly
proper that gate fees should be charged and
that the skilled players should be paid liberally
for entertaining us. Why, then, should inter-
collegiate associations adopt such drastic rules
against college athletic professionalism and
why should faculties attempt to enforce these
rules so rigidly? This is certainly not done
solely in order to insure fair play in inter-
collegiate contests.
The fact is that mere playing games for
compensation, in the college or out of it, is not
SCIENCE
[Vou. LV, No. 1429
inherently immoral or wrong in any way, ex-
cept as it may bear some relation to the vital
concerns of the college in its efforts to promote
true education. But we are insistent that the
least taint of professionalism shall be kept out
of our college athletics because we know that
whenever we admit it we shade our scholastic
standards. If petty, technical professionalism
may enter then unlimited professionalism and
commercialism to the last degree can not be
excluded.
I am saying no more than what is fairly
common knowledge when I state that there is
a sort of underground activity to-day that is
exerting every effort to cireumvent and evade
our regulations concerning amateurism. How-
ever much some of us may boast of the “clean-
ness” of athletics in our various colleges, we
all know perfectly well that the cases of viola-
tions of the rules that are occasionally brought
to light are merely the more obvious ones. We
disqualify our players for participating in a
summer game in a village of a neighboring
state but we harbor far more serious cases of
real professionalism in the boys who are pro-
vided with workless jobs, fraternity homes and
other outside-financed “education” in order
that they may take important places on ath-
letic teams. These boys are hunted out while
yet in the secondary schools and they are
brought to college and kept there by an organ-
ized effort on the part of men who, in some
cases, care nothing for educational standards
or for education itself, but who know athletic
excellence when they see it and who are deter-
mined to have the best of it for the college of
their choice. This work is done quietly, as a
rule. Occasionally some novice in the business
makes a slip and an uproar ensues. This has
happened on several occasions, quite recently.
As a result, it is apparent to a close observer
that the interests that work for commercialism
are now scurrying to cover. They realize that
they have been riding to a fall and in order
to save intercollegiate competition from the
impending wreck they have become loud in
their pharisaical professions of a determination
to see that the law is obeyed and that college
sports are kept clean. But even in this they
are careful to keep attention focused upon the
May 19, 1922]
summer-playing bugaboo, so that the more seri-
ous issues are obscured.
Visualize, if you will, the college teacher,—
instructor, professor, department head or
dean,—making his final summary of grades for
the members of his classes or sending in his
mid-semester reports of delinquencies. Ima-
gine that you see the name of one of these star
athletes upon the list of those who have been
found wanting. No very vivid imagination is
required to complete the picture. It is quite
likely that many of our teachers are upright
enough and strong enough to resist the pres-
sure which will result. Also it is quite possible
that many are not so strong. This is particu-
larly true of the teachers who hold the more
subordinate positions and who feel themselves
less secure in their standing. And the assault
against class standards is not, by any means,
confined to actual threats against individual
instructors. A more subtle influence in the
form of a very human and a very universal
desire for personal popularity and a lurking
fear of loss of dearly earned prestige finally
leads to the same result. As individuals and
as faculties we feel more and more strongly a
timidity in the enforcement of rules,—not only
rules of scholarship but rules of every deserip-
tion. This, I am firmly convinced, is the basic
cause for the now too obvious drift of our
colleges toward laxness in morale and toward
the lowering of the standards of work required
of those who are to receive our degrees. The
futility of our most earnest efforts toward
inspiring and_ effective teaching becomes
increasingly apparent.
Fellow chemists, this is a problem which
affects all of us most vitally. We have had an
enormous amount of publicity for the fact that
American science was not, before the war, able
to cope with German science and various rea-
sons haye been assigned for this undoubted
fact. The efficiency of American science was
suddenly increased, during our war period, by
the spur of life-and-death necessity. But this
spur no longer exists and if our chemistry,—
research, applied or teaching,—is to continue
to hold its own we must see to it that our
young college graduates go forth into the
struggle fully equipped with well trained minds
SCIENCE
527
and hands,—vwell trained not only in the ability
to do certain routine tasks that we have set for
them in the colleges and universities, or in the
ability to follow slavishly in the methods and
habits of thought of their teachers, but broadly
trained in scientific fundamentals, in general
culture and in the ability to do independent
and profound thinking on important matters
of science and of life. This they do not now
acquire as they could and as they should.
Whether or not you may agree with the con-
clusions I am about to draw, I do not believe
that the essential facts as I have already stated
them can successfully be denied. I do not be-
lieve that we can make any very great head-
way in our effort to stop the obvious decline
in our standards of scientific education until
we can succeed in limiting the distractions of
campus activities to sane and reasonable values.
We can not bring about this change until we
divorce the educational system from the
present commercialized system of intercolle-
giate athletics. And, finally, the ineubus of
commercialized athletics can not be shaken off
until we throw out of our educational system
all of our extravagantly paid professional
coaches. For a fraction of a year of work we
pay a football coach three or four times as
much as an able and experienced professor in
any other department »will receive. We need
not feel any surprise when we discover that he
has done the best he could to earn this salary
and thus to insure permanency in his position,
or that he has employed every means in his
power to obtain the best material for his teams,
rules or no rules, and we need not expect that
anything short of constant vigilance will serve
to eurb his extra-legal activities. His job is to
develop a team that will be able to outplay the
teams of approximately seven other colleges
in as many contests of approximately forty
minutes each, per season. He is going to do
this to the best of his ability, regardless of
cost, and we may think as we please about it.
Our colleges are spending relatively enor-
mous sums upon athletic activities whose end
is not, in any sense, physical development of
the students but solely the winning of games
and championships, while the educational needs
are grievously suffering, through lack of sup-
528
port. This spectacle is not one that can be
contemplated with equanimity by those who
have faith in education and hope for its future
development. We are losing the sense of per-
spective in educational affairs and we may not
expect to elevate our colleges from a position
of mediocrity in scientific training until we
shall have reaequired this sense. This happy
consummation is not to be attained so long as
we remain in the present state of competitive
hysteria or so long as we continue to provide
disproportionate support for an activity that
has no relation to scientific or other education
except that of obstruction to it. I do not envy
those colleges of the United States that are
planning to sink millions in athletic stadia. I
verily believe that the day will come when
these colossal monuments to the suicidal folly
of a so-called “educational” system will be an
offense to the eyes of believers in true learning,
for in that day we shall find it hard to convince
our critics that we do not esteem the spectacle
of two hundred and eighty minutes of actual
playing of football each year as of greater
importance than the training of American
youth in the science of chemistry.
And now, in what way can there be any
truth in the statement made in the earlier por-
tion of this paper, to the effect that the men
who are looking to the college to supply trained
chemists, as well as trained scientists in other
fields, are directly responsible for the continu-
ance of this condition? Simply by this: that
these people are, almost without exception,
college and university alumni and that organ-
ized alumni activities concern themselves
almost exclusively with efforts to further ath-
letic successes in their. colleges, to the neglect
of opportunities to better educational condi-
tions. This is certainly not because of any
desire to hamper the educational work of the
college. Quite the opposite is the case. They
do not busy themselves so much with other
modes of assistance, merely because for some
reason it has not occurred to them that such
assistance is possible. They believe that the
college needs advertising and they have repeat-
ed so often that they nearly believe it, the old
fallacy that athletic prowess is the best adver-
tisement for institutions of higher learning.
SCIENCE
[Vou. LV, No. 1429
I hope that I do not merit the appellation
of “alarmist” but I do sincerely believe that
the present condition and the present trend of
scientific education is such as to give thought-
ful people cause for concern, and I believe
that we shall not get very far in our attempts
to improve matters until we elect to discuss
these things fearlessly and openly and then
courageously to act upon our ecunviections. In
the inspired words of Vernon Kellogg :! “It is
incredible that in this all-important matter of
getting our higher education straightened out
we shall go on indefinitely acting as if we were
helpless. Let the college or the university that
wishes to do the greatest thing just now to be
done for higher education and true learning in
America step forward and boldly do the un-
usual thing. Let it devote the most of its
energies to the most important part of its
work. It will soon not be alone in its doing.
It will become a prophet with honor in its
own land.”
The choice of courses is now ours. If we
fail to exercise that choice in the name of true
education and true science, we may later find
that the decision has passed from our grasp.
Or can it be that, as history has so often re-
corded of individuals, of organizations and of
nations, we shall continue simply to drift until
the accumulation of disaster shall shock us
into realization?

welcomes all who listen in. It is a great
pleasure in this first radio entomological lec-
ture to be specifically authorized to convey to
Madison entomologists and others the greetings
and best wishes of Dr. Howard, chief of the
Federal Bureau of Entomology, Dr. Gibson,
Dominion entomologist of Canada, and the
presidents of the older entomological societies
on the eastern coast, namely, Cambridge, New
York, Brooklyn, Washington and Philadel-
phia, the last founded in 1859, the oldest of its
kind in the country and with its founder, Ezra
T. Cresson, still active. The pioneer and vet-
eran entomologist of Canada, Dr. Bethune, has
authorized the extension of his congratulations
and best wishes to present day workers. We
would also express our appreciation to the
General Electrie Company of Schenectady for
placing this lecture upon its program.
There are great possibilities in broadcasting
and, for the purpose of determining its present
value, the speaker requests reports by mail
giving the number of entomologists at each
unit receiving this lecture. Crop and market
reports are broadcasted. Why not warnings of
insect depredations? Regional programs and
lectures by visiting specialists are very desir-
able present day possibilities.
This has been ealled the age of man. Is it
not really the age of insects? They occur
almost everywhere. They actually imperil our
existence by attacking crops, destroying for-
ests, annoying and worrying domestic animals,
and are well known carriers of deadly infec-
tions, such as typhoid fever, yellow fever,
cholera and sleeping sickness. Were it not for
the beneficent activities of birds and many
other natural agents, we would be overwhelmed
by the numerous pests contemptuously desig-
nated as bugs. There are in New York State
some 20,000 different. species of insects and
perhaps 100 entomologists engaged in collect-
ing and studying them. There are presumably
more than 100,000 species in the United States
with over 1,000 entomologists and in - the
entire world a million to ten million different
species of insects (a large proportion un-
known) and a relatively much smaller group
engaged in their study. Each of these insects
occurs in four distinct stages, namely, the egg,
SCIENCE
529
the maggot or caterpillar, the pupa or chrysa-
lis and the adult or perfect insect, conse-
quently the entomologists of the world are en-
gaged in the stupendous task of classifying and
learning the habits of four to forty million
different forms. Accurate differentiation must
precede investigation of life histories, other-
wise deplorable confusion is almost inevitable.
There is no group in the animal, the vegetable
or the inorganic kingdoms which presents so
many diversities as the exceedingly numerous
and varied forms known as inseets. It usually
takes several years and frequently much longer
to work out a satisfactory life story of even
one insect, consequently a limitless field is
before us. We extend to radio “bugs” and
others interested an invitation to join in ex-
ploring and making known this vast realm of
the undiscovered.
Man is inelined to congratulate himself upon
his wonderful progress, forgetting that in many
cases he has yet to reach the degree of perfec-
tion seen in numerous animals. The recently
developed monoplane, for example, does not
differ greatly in its general proportions from
those of our hawk moths, and the biplane is
almost a duplicate of a pair of dragon flies,
one flying above the other; both models that
have been favorites in the insect world for
thousands of years. Dare any man say that
our latest advancement in applied science,
namely, the radio telephone, is more than a
relatively crude modification of methods which
have been used by insects for countless ages?
Radio “bugs” are rightfully proud of their
aerials or antenne, yet they have developed
relatively few types and apparently have not
learned, except in a very general way, of the
million or more different kinds of insect anten-
ne, each admirably adapted to a specific pur-
pose and some wonderfully suggestive of aerial
communication.
Ages ago the gall midges, minute flies which
produce galls on many plants, learned the ad-
vantages of elevated or elongated antenne and
we find here species which have solved the
problem by the development of greatly elon-
gated antennal segments, thus increasing very
materially the length of the entire organ and
others which have attained the same end
530
through a doubling or trebling of the normal
number of segments or joints. As a result,
some have antenne twice as long as the body.
Each segment is a unit and though the com-
parison may not be a strictly accurate one, we
are inclined to regard the antennal segments
as linked in multiple units.
It is well known that the antenne of many
insects have very efficient olfactory and aud-
itory structures. The latter may be simple
hairs springing from sensory pits, whorls of
hairs or even more complex structures.
The radio enthusiast would certainly be inter-
ested in an aerial or antenna of the multiple
inverted umbrella type, the arms of the um-
brellas being loops and in some forms greatly
extended on one side, presumably for directive
receiving; the umbrellas arranged in double
or triple series in multiple units mounted with
flexible connections and an articulate base per-
mitting limited rotation. Such structures are
found in gall midges.
We would eall attention to the peculiar cir-
cumfila or encircling threads supported by
numerous short stems entering sensory pits or
detectors, the latter within the antennal seg-
ments. The simplest type of cireumfilum is a
low thread or circle, not a coil, near the base of
the segment and frequently connected by a
filament on one face with a similar circle near
the opposite extremity. These threads may be
modified and follow a sinuous or wavy course
instead of a straight one; they may be greatly
increased in number to form an enclosing net
work, suggestive of the bed spring aerial; the
portions between the supporting stems may be
greatly stretched or drawn out as it were to
form relatively enormous loops and in some
we have the loops on one side of the antennx
very greatly produced. We may even find in
some antenne a combination of the low and
simple type together with highly developed
loops. There is one group where these struc-
tures are modified in such a curious way as to
resemble miniature horse shoes upon opposite
sides of each segment; the supporting stems
suggesting the nails used for the attachment of
horse shoes.
There are over a thousand variations in gall
midge antenne, presumably for cause. Solo-
mon advised some of his fellow mortals to con-

sider the ant. May we suggest to radio enthu-
siasts a similar attitude toward gall midges—
master builders of antenne which are both the
admiration and despair of man.
Concluding, may we register faith in radio
and radio antenne, anticipating through them
closer and more helpful relations with fellow
men.

JOHN CASPER BRANNER
THe following resolution was passed at a
meeting of the Academic Council of Stanford
University held April 7, 1922:
_ As witness of our affection for Dr. Branner
and respect for~his memory, we desire to make
our own and incorporate (in part) in the minutes
of the Academie Council the appreciation pre-
pared for the Illustrated Review by his friend
and colleague, Professor Stillman:
“*TIn the death on March first of President
Emeritus John Casper Branner, Stanford Uni-
versity loses one of its most distinguished schol-
ars, one of its greatest teachers and most respect-
ed and beloved personalities.
“‘Dr. Branner was born in New Market, Ten-
nesee, on July 4, 1850. He attended school at
Maury Academy in Dandridge, Tennessee, and
later enrolled at Maryville College. At the age
of eighteen he entered Cornell University, where
he received his bachelor’s degree.
‘‘While still an undergraduate he was selected
(1875) by Professor Charles F. Hartt to assist
him in a geological survey of Brazil, which ocea-
sioned several years of work in Brazilian geology,
In 1882 he was again commissioned, by the
United States Government, to go to South America
to investigate insects injurious to cotton and
sugar-cane industries. From 1883 to 1885 he was
engaged by the Pennsylvania Geological Survey
to make a topographic map of the Lackawanna
Valley.
‘(When David Starr Jordan became president
of the University of Indiana in 1885, he ap-
pointed his Cornell college and fraternity mate
to the professorship of geology at that institution,
a position he held until again called by Dr.
Jordan to the similar chair in Stanford Univer-
sity. In the meantime he acted (1887-1892) as
state geologist of Arkansas, while retaining his
chair at Indiana.
‘¢From 1891 until his retirement from the uni-
May 19, 1922
versity in 1915, Dr. Branner occupied the head-
ship of the department of geology and mining,
holding also the office of vice-president of the
university from 1898 to 1913. Upon the creation
of the title of chancellor for Dr. Jordan, in 1913,
Professor Branner was elected president, a posi-
tion which he held until January, 1916, when he
also retired under the age limit established by
the university, and became president emeritus.
During his years of service at Stanford, Dr.
Branner found occasion to direct or participate in
professional missions, such as his expedition to
Brazil under the patronage of Alexander Agassiz
in 1899, and again in 1907-1908. He was also
one of the special government commissioners on
the Panama Canal, and on the California earth-
quake of 1906.
““The scientific service of Professor
has been widely recognized. He was a member of
the National Academy of Sciences, the American
Philosophical Society, was president (1904) of the
American Geological Society, vice-president
(1890) of the American Association for the Ad-
vancement of Science, held membership in the
Geological Societies of London, Edinburgh,
France, was president (1911) of the American
Seismological Society, and was a member of
geologic and geographic societies of several Bra-
zilian states and of other countries. He has re-
ceived the degrees of Ph.D. from Indiana Uni-
versity in 1885, of LL.D. from the University of
Arkansas in 1897, from Maryville College in 1909,
and from the University of California in 1915,
and the degree of Se.D. from the University of
Chicago in 1916.
‘His publications are numerous and, while the
great majority are on geology, many evidence the
breadth of his active interests in botany, ento-
mology and other lines of natural sciences. His
grammar of the Portuguese language (now in its
fourth edition) grew out of his Brazilian experi-
ence. His bibliography of Clays and Ceramics,
an important compilation; the ‘‘How and Why
Stories,’’ a charming collection of southern negro
dialect myths (1921); his genealogy of ‘‘ Casper
Branner of Virginia and His Descendants’’; and
his recently completely but as yet unpublished
translation from the Portuguese of . Alexandre
Herculano’s Establishment of the Inquisition in
Portugal, all evidence his breadth of interests and
his tireless energy. ¥
““As a teacher Professor Branner exerted upon
his students an influence which inspired them to
their best efforts. His broad experience, his own
sytematie and untiring research, his realization
Branner

531
of the supreme importance of practical experience
as the final test of all theories, were well calcu-
lated to stimulate the ability and energy of his
students, while his simple, sincere, and sympa-
thetic personality attached them to him with a
rare devotion. ’’
Dr. Branner’s attitude toward the office of
president was characteristically expressed in his
inaugural address:
“*T am here to serve you in every way in my
power and in everything that pertains to your
work as instructors in the university and as
scholars interested .in your own special lines of
work. I expect and I intend to be the servant of
every member of this faculty except myself. I
consider the support I can give you my most
important duty, and it will be my _ greatest
pleasure.’’
In becoming president of the university, Dr.
did not cease to be teacher and col-
league. He made the problems of all the depart-
ments his own. In his relations with students
and faeulty the informality of attitude and high
courtesy were unchanged. He maintained the
same dignified simplicity he had exhibited as
executive head of his department.
Dr. Branner’s life is a great heritage for Stan-
Branner
ford University, for California, and for the
nation.

SCIENTIFIC EVENTS
A COUNT OF BIRDS
RENEWED interest in the bird population of
the United States has led to a revival of the
efforts, begun in 1914, by the Biological Survey
of the United States Department of Agricul-
ture, to collect information on the number and
distribution of the birds breeding in this
country. Counts have been made each suc-
ceeding year, and interested persons who are
thoroughly familiar with the breeding birds of
their respective vicinities are asked to aid in
the work. By continuing these counts over a
period of years and counting the same areas
each year, knowledge can be gained not only
of our total bird population but also of its
fluctuations from year to year. The counts,
moreover, will greatly help in determining what
effect the present state and federal laws have
on the inerease of game and_ insectivorous
birds. The department hopes that counts will
be continued on all land where they have pre-
viously been made, and it especially desires to
obtain also series of counts indicating the bird
life on the plains; on the deserts, both with and
without irrigation, and in the southern and
western states.
It might be well to select new areas where
physical conditions are not likely to change
much for a number of years, so that if suc-
ceeding annual counts show changes in bird
population it will be known that they are not
due to changed environment brought about by
On the other hand, there is much to be
learned regarding the adaptation of birds to
changes of environment; any area therefore on
which reports can be made year after year may
be chosen, even though conditions are likely to
change. Possible inability to repeat a count
on the same tract need not, however, deter
any one from making the count this year.
The height of the breeding season should be
chosen for this work. In the latitude of Wash-
ington, D. C., at latitude 39 degrees, May 30
is about the right date for the first count. In
the latitude of Boston the work should not
begin until a week later; while south of Wash-
ington a date still earlier than May 30 should
be selected. The department wants to learn
how many pairs of birds actually nest within
the selected area. Birds that visit the area
only for feeding purposes must not be counted,
no matter how close their nests may be to the
boundary line.
man.
Several kinds of counts are needed for a
study of the relative abundance of birds under
changing and stationary conditions. It is
hoped that many persons interested in bird life
will make one or more counts this season. If
only one count is made, the tract selected should
represent average farm conditions for the
locality, should not have an undue amount of
woodland or orchard, and should contain not
less than forty acres a quarter of a mile square
nor more than eighty acres. If there is an
isolated piece of woodland of from ten to
twenty acres conveniently near, a separate
count of the birds nesting there will be useful
in addition to the count on the rest of the farm.
In this case the report, in addition to specify-
SCIENCE.
[Vou. LV, No. 1429
ing the size and exact boundaries of the area,
should give the principal kinds of trees, and
whether there is much or little underbrush.
A third count is desired of some definite area
of woodland, which is part of a larger timbered
tract. Still a fourth count, supplementary to
these is needed. The average farm in the
- northeastern states contains about one hundred
acres, and the average count hitherto has been
of the birds nesting on the fifty acres of the
farm nearest to and including the farm build-
ings. It is now necessary to obtain counts also
of the remainder of the farm, the wilder part
containing no buildings, especially on the same
farms where counts about the buildings have
already been made. Besides these, counts on
any other kinds of land are much desired for

THE CHEMICAL EXPOSITION!
Tue Eighth National Exposition of Chemical
Industries will be held this year in the Grand
Central Palace, New York, during the week of
September 11 to 16, inclusive. It will follow
immediately upon the fall meeting of the
American Chemical Society. The early date
will give college and university men an oppor-
tunity to see the exhibits before the beginning
of the college year. There is much in this
coming exposition to interest university men.
Each floor has exhibits of laboratory apparatus,
and one floor has a considerable group of this
type of equipment. Many new pieces of ap-
paratus, new chemical compounds, and other
material and instruments will be found here.
The interests for industrial chemistry in the
exposition are wide and varied: from raw ma-
terials in minerals, ores, manufacturing crudes
or by-products, through the range of ma-

ing Chemistry.

chinery, apparatus and equipment and instru-
ments for control, precision, recording, gaging
and measuring, and a thousand other items
used in converting the raw materials into the
finished products. The finished products them-
selves, whether they be organic, inorganic,
solid, liquid, gaseous, or of any other form, are
all to be there. Many new things upon which
manufacturers were working when the war
ended and which have been more leisurely per-
feeted since will be shown for the first time.
Industrial progress continually calls for greater
advancement and perfection in manufacture,
and each year sees many notable improvements
upon the exhibits in the exposition. Counting
only these, the time of technical and business
men is well spent in inquiring into the exhibits.
One exhibitor, who for the past few years has
been devoting time to the perfection of a new
form of apparatus, said the other day that it is
now when men have time to spare for considera-
tion of these things that he expects a consider-
ably larger and more interested attendance in
his booth. ‘When the plants are idle as they
are now, the most progressive companies are
examining into our apparatus, and a remark-
able thing is that we are making some installa-
tions in plants which are now closed, so that
when they begin work they will be in better
position than ever and have an advantage in
taking this opportunity to prepare to reduce
their costs for the future. I’m looking for
many more such openings through our exhibit
and with considerable enthusiasm for the entire
exposition.”
The managers report that three full floors of
the Grand Central Palace are already taken
for the exposition and a part of a fourth. They
expect all space will be engaged before the
opening date. Already, 303 exhibitors have
contracted for space.
The exposition will contain two interesting
special sections: one upon the subject of fuel
economy, where exhibits intended for the more
efficient use of fuel, its combusion, distribution,
or control will be made. .The other will
deal with shipping containers, including the
container itself, whether of metal, wood, fiber,
paper, glass or in cooperage products of slack
and tight barrels, tanks and towers, and with
SCIENCE
538
machinery for packaging, labeling, handling,
and conveying the packaged material and mark-
ing it ready for final shipment.
Work upon the program has not yet been
actively undertaken but it may be expected to
compare more than favorably with the high
standards of the preceding expositions. The
management have returned to the Grand Cen-
tral Palace with their offices, and all inquiries
should be directed there.

EXCHANGE PROFESSOR TO FRANCE IN
ENGINEERING AND APPLIED SCIENCE
Dean JoHN Frazer, of the Towne Scientific
School of the University of Pennsylvania and
professor of chemistry, has been chosen as ex-
change professor to France for the coming
academic year, by the committee on exchange
with France of professors of engineering and
applied science, representing Harvard, Yale,
Columbia, Cornell, Massachusetts Institute of
Technology, the Johns Hopkins and the Uni-
versity of Pennsylvania.
The movement for the annual exchange with
France of a professor of applied science had
its origin as the result of a letter written
shortly before his death by the late President
Richard Maclaurin, of the Massachusetts Insti-
tute of Technology.
tion responded very cordially to the offer for
the annual exchange of a professor and select-
ed for their first representative Professor
Jacques Cavalier, rector of the University of
Toulouse, and a well-known authority on metal-
lurgical chemistry, who divided his time during
the current academic year among the seven
cooperating institutions, namely, Columbia,
Cornell, Harvard, Johns Hopkins, Massachu-
setts Institute of Technology, Pennsylvania
and Yale.
The American universities selected as their
first outgoing representative for the first year
Dr. Arthur E. Kennelly, professor of elec-
trical engineering at. Harvard University and
The French administra-
SCIENCE
[Vou. LV, No. 1429
the Massachusetts Institute of Technology. He
has met with great success in his undertaking in
France, and in addition to lecturing before
numerous French technical schools was assigned
by the French educational authorities, through
M. Petit Dutaillis, minister of public instruc-
tion in France, to spend several weeks at the
Universities of Paris, Grenoble, Lyons, Mar-
seilles, Toulouse, Bordeaux, Nancy and Lille,
giving in each a course of lectures, some tech-
nical and others of a more general character.
Dean Frazer in the course of his work of
lecturing in French before the various univer-
sities and scientific societies of France, will
have favorable opportunities of studying at
close range French educational methods, espe-
cially as applied to science.
Dr. Frazer represents the fourth generation
to be graduated from the University of Penn-
sylvania, and the third generation to be con-
nected with its faculties. His grandfather,
John Fries Frazer, from 1844 till his death in
1872, was professor of natural philosophy
and chemistry in the University of Pennsyl-
vania and vice-provost from 1855 to 1862. He
was one of the incorporators of the National
Academy of Sciences in 1863. His father, Dr.
Persifor Frazer, became professor of chemistry
in 1872, which chair he held until his appoint-
ment to the Second Geological Survey of Penn-
sylvania. He died in 1909. Dr. John Frazer
was born in Paris, France, on February 5, 1882.
In 1904 he was appointed instructor in chemis-
try, being later promoted to assistant professor-
ship and subsequently to a professorship. In
1912, upon the reorganization of the old col-
lege, he became dean of the Towne Scientific
School, which position he has held since, except
while on leave of absence when in the service
in 1918.

Av a meeting of the advisory council of the
Phipps Institute, Philadelphia, April 29, gifts
totaling $150,000 were announced. The sum of
$25,000 will be given yearly for five years by
the Carnegie Corporation, for research pur-
poses. Dr. Josiah H. Penniman, acting pro-
vost of the University of Pennsylvania, stated
that the board of: trustees had voted $25,000 to
be given during the next two years to the insti-
tute. The family of Henry Phipps announced
that they pledged $500,000 to the endowment
fund, provided an additional $2,500,000 be
raised.
Tue fund for the establishment of the Har-
vard School of Public Health will be entitled
the Henry Pickering Walcott Fund in honor
of the senior member of the Harvard Corpora-
tion. As has already been announced, the
Rockefeller Foundation has agreed to con-
tribute at once $1,500,000 and eventually
$500,000 in addition; these amounts will be
inereased by a fund of $1,000,000 provided by
the university and also by the income of more
than $3,000,000 which is now being expended
by the university in various departments which
will be incorporated in the school. It will prob-
ably open next year for instruction and
research in the field of public health. It will
be closely allied to the Harvard Medical School,
and Dr. David L. Edsall will serve as dean of
both schools. Certain departments now organ-
ized under the Medical School, such as those
of industrial hygiene and tropical medicine,
will become part of the new school, which will
also develop and enlarge the work of the School
of Public Health now jointly conducted by
Harvard and the Massachusetts Institute of
Technology.
Tue Board of Research Studies of the Uni-
versity of Cambridge, in a report on the ad-
mission of research students, records that steps
have been taken to concentrate in the board the
power of admission of research students, and
it is hoped that this will tend towards the
preservation of a uniform standard of quali-
fication. Secondly, they record that it has
been decided to institute the degrees of M.Litt.
SCIENCE
937
and M.Se. The regulations for these degrees
appear in the current number of the Reporter.
The number of research students admitted
when the last report was presented was 72.
Since then 71 have been admitted, making in
all 143. These figures, however, hardly repre-
sent the comparative number of admissions
this year and last, for at the beginning many
already at work under the old regulations for
the B.A. degree were permitted to transfer.
During the year two students withdrew their
names. The proportion of Cambridge gradu-
ates among the students now admitted has
risen. The large number of graduates of other
universities within the British Isles remains a
feature. Those from Canada and the United
States are fewer than may be anticipated when
the degree is better known, their combined
number—25—hbeing approximately that of
those coming from the Indian Empire.
Tue British Board of Trade has issued an
order exempting certain German scientific and
other periodicals from the provisions of the
German Reparation Act of 1921. Any article
is exempted “being a publication in the Ger-

tion of the commissioners of customs and excise
to be a periodical publication of a German
learned society, or other scientific or philosoph-
ical periodical publication.”

DISCUSSION AND CORRESPOND-
ENCE
DECEREBRATION IN BIRDS
THE recent observations of Shakleet on
decerebrate pigeons serve to emphasize some
features of the physiology of the central ner-
vous system of special interest to workers in
this line. The long period of survival—near-
ly twelye months—and the new features of
decerebrate behavior recorded, again call atten-
tion to the possibilities of this method of ex-
perimentation as well as to some of the dangers
of its interpretation.
The positive result of the return of the
drinking reaction, not hitherto obtained in
1Am, Journ. Physiol., Vol. lv, p. 65, 1921.
SCIENCE
[Vou. LV, No. 1429
similar work, points to a greater flexibility in
the neural mechanism than we have usually
ascribed to it and falls into line with some of
the newer conceptions that have been gain-
ing foothold in the field of brain function.
Whatever interpretation of the results may be
made regarding the process by which such
restoration of function 1s accomplished, every-
one must be impressed by its extent and adap-
tative importance.
The differences between the present work
and the results of Martin and Rich? to which
Shaklee refers deserve a word of comment.
Aside from the difference in species used,
which may or may not have influenced the
results, it should be emphasized that Martin
and Rich operated on newly hatched chicks,
thus excluding the influence of individual
habit or experience prior to decerebration,
while Shaklee used adult pigeons. Another
factor is the distinctly longer period of sur-
vival in the pigeons.
The highly speculative interpretation placed
upon these very interesting results may be
passed over with the exception of one or two
points. It seems surprising that, if the are
upon which the drinking reaction depends is
of the deeply ingrained type postulated, it
did not show activity for 32 days. In con-
sidering the feeding reaction the importance
of tasté seems strangely overstressed. A hard
grain in the tip of the beak could give rise
to very little more taste than do the bits of
gravel which are also normally swallowed by
birds.
The interpretation of work of this nature
must be cautious. The facts of re-education
(I use the term without implication as to the
method by which restoration or substitution
is accomplished) in man and animals show that
many things can be done which are never
normally done in the lives of the vast majority
of the individuals or of their ancestors. As
when storms damage telephone and telegraph
lines, communication can be effectively estab-
lished by routes never normally used, so in the
nervous system possible and efficient ares and
2 Am. Journ. Physiol., Vol. xlvi, p. 396, 1918.
May 19, 1922
pathways may exist which are never normally
traversed.
Only one explanation of the restoration of
function is offered in the article under con-
sideration, i. e., that the subcortical ares are
the more primitive and are sufficiently retained
in adult pigeons after decerebration to make
possible the carrying out of normal drinking
reactions.
Another explanation is also possible. Many
writers have claimed that certain habits, aris-
ing in the first instance through activities
involving the cortex, later are passed on com-
pletely to subcortical centers. As Herrick®
points out, these acquired automatisms may
so closely resemble inherited reflexes as to be
indistinguishable in the absence of the history
of their development. If it is here assumed
that the drinking reaction established during
the life of the pigeon is transferred in large
part to subcortical structures, its retention
after decerebration would seem to be expected,
while in the case of the chick, decerebrated be-
fore such reactions were built up, no such ap-
pearance could be looked for. It might also
be argued that the feeding reaction, being more
complicated, was not so completely transferred
from the cortical region as to be effective after
decerebration.
That such an assumption may be justified is
indicated by the work of Franz and Lashley‘,
who found from numerous careful experiments
with white rats that extensive cortical lesions
did not usually affect the retention of most
habits due to previous training, nor did they
prevent the formation of new habits. The
authors also report that in the cat and monkey
where the frontal portion of the cortex is
normally utilized in the formation of certain
habits, these habits, if long practiced, are still
carried out in the ordinary way after the abla-
tion of the frontal cortex. This work as well
as. its continuation by Lashley® clearly shows
that the classical picture of the decerebrate
animal is in large measure erroneous and must
be carefully revised and with it the entire con-
ception of the physiology of the central nerv-

THE BITE OF LACTRODECTUS MACTANS
In Science for January 13, F. R. Welsh
writes on “Poisonous Spiders.” In regard to
the “Black Widow,” Lactrodectus mactans, he
quotes Dr. McCook as of the opinion that the
bite of this spider is “in most instances of small
consequence.” During the past two years the
writer has had ealled to his attention four cases
of attacks by this spider on human beings.
These were all reported by practising physicians
who sent in the spiders for identification. All
four cases were those of men who were bitten
on the penis while using outside closets. In
every case the results were of a very serious
nature. The patients suffered intense pain ac-
companied by severe abdominal disturbances,
convulsions and delirium. In one ease the ab-
dominal pain was so intense and pronounced
that the patient who had been sent to a hos-
pital in a distant city was, upon arrival,
promptly operated upon for appendicitis. The
severe symptoms lasted from twenty-four
hours in one man to over a week in the case of
another. In a third ease the physician reported
four days after the patient had been bitten
that he was “not yet out of danger.” However
all ultimately recovered. Two of these men
were bitten the same day in the same closet
and presumably by the same spider, indicating
that the spider does not exhaust her venom by
one bite.
These experiences would indicate that the
bite of this species, at least when administered
in a tender, part of the body, is very serious,
exceedingly painful, and even dangerous.

WATER-IMMERSION OBJECTIVES
I wis to eall the attention of those biologists
who use the microscope to the value of the
much neglected water-immersion objective. Its
inferiority to the oil-immersion in the matter
of numerical aperture, and consequently in
power of resolution, has led. many microscop-
040
ists to lose sight of its peculiar advantages for
certain kinds of work. The lower angular
aperture obtainable with water contact as com-
pared with cedar oil, is compensated for in
several ways: first, it gives a longer working
distance, due to the necessarily narrower angle

where v is the component of the velocity per-

We have remarked in the preceding that the
velocity of light at oc is equal to 1 in the units

chosen. If we denote it by ¢ in any system of
units, we may formulate the law as follows:
Two bodies attract one another inversely as
the square of their distance and directly as the
product of their masses and (1 + 3v°/c?),
where v is the component of their relative ve-
locity perpendicular to the line joining the
bodies.
The form (1) is obtained from the Einstein
theory on the hypothesis that the planet is
small in comparison with the sun. It may be
that the above law applies only to this case.
However, it may be that the law would work
if the bodies were approximately of the same
mass. As formulated the law enables one to
set up the differential equations of » bodies in
a manner analogous to the classical theory. It
would be interesting to know whether known
discrepancies in the motion of the moon would
be overcome by the use of this law.
Although the term 3v7/c? produces an ob-
servable effect only in the ease of Mercury, it
may produce a significant effect in molecular
motion.

where w may be interpreted as the angular
velocity of the light about the sun. Thus it is
the term 3mo* in (13) which accounts for the
deflection of light, and the term m/r? does
not enter. Einstein and his followers have cal-
culated the deviation of light by noting that
the velocity changes in a manner analogous to
that of a refracting medium, and by applying
Huygen’s principle. Since the same term ap-
pears in the attraction of a planet, it may
very well be that the sun affects the medium
through which both the light and planets pass,
and that the difference between Newton’s law
and (13) is due to this situation. From ‘this
point of view one would expect that the law

SECTION F—ZOOLOGICAL SCIENCES AND
ASSOCIATED SOCIETIES
Ar the Toronto meeting of the American
Association for the Advancement of Science,
December 27-31, 1921, Section F (Zoology)
offered no separate program, but met jointly
with the American Society of Zoologists. The
program was arranged by the latter society.
Six joint sessions were held, the program
including 101 titles distributed by subject as
follows: embryology, 4; cytology, 8; compara-
tive anatomy, 7; evolution and genetics, 24;
ecology and zoogeography (with the Ecological
Society of America), 13; general zoology, 2;
protozoology, 2; parasitology, 22; comparative
and general physiology, 17; unclassified, 2.
The session of Friday afternoon, December
30, was devoted to a symposium on ortho-
genesis. A biologists’ smoker was held Wednes-
day evening, December 28, and the zoologists’
dinner Friday evening, December 30.
The business meeting of Section F' took place
at the morning session on December 29, with
Vice-president Kofoid acting as chairman.
M. M. Metealf is vice-president for Section F
for 1922. J. A. Detlefsen was elected a mem-
ber of the section committee for four years in
place of the retiring member, A. M. Reese.
F. R. Lille presented the following resolu-
tions drawn up by a conference of representa-
tives of the biological societies in regard to a
proposed federation of biological societies:
RESOLVED: 1. That it is the sense of this con-
ference that an inter-society conference should be
called to study and report upon the feasibility
of federation of the biological societies and to
develop plans for the said federation.
2. That for the purpose of effecting such an
organization, each society, and Sections F and G
of the American Association for the Advance-
ment of Science, be requested to designate its
president and secretary as members of an inter-
May 26, 1922]
society council which shall be authorized (1) to
deal with all matters of common interest, such as
pooling of programs, that are consistent with the
existing regulations of the constituent societies,
and (2) to draw up proposals for a constitution
and by-laws of a federation of the societies in
question, and to present them for action at the
next annual meeting.
The Section voted that the resolutions of the
conference be adopted.
Independent programs were arranged by the
following societies affiliated with Section F—
The Entomological Society of America, The
American Association of Economie Entomolo-
gists; and by the following societies affiliated
with Sections F and G jointly—The American
Society of Naturalists, The Ecological Society
of America, The American Microscopical So-
ciety (business meeting only), The American
Nature-Study Society.

SECTION G—BOTANICAL SCIENCES AND
ASSOCIATED SOCIETIES
Section G held its session on Wednesday
afternoon, December 28, 1921, in conjunction
with the Botanical Society of America and the
American Phytopathological Society. There
was a large attendance at this meeting, and the
symposium, though involving several papers,
was not unduly long. Professor Rodney H.
True, retiring vice-president for Section G,
delivered his address on “The physiological
significance of caleium for higher green plants,”
which has been published in Science, Vol. LV,
p. 1, January 6, 1922. The vice-presidential
address was followed by a symposium on “The
Species Concept,” at which the following
papers were read: (1) “From the viewpoint
of the systematist,”’ Charles F. Millspaugh;
(2) “From the viewpoint of the geneticist,”
George H. Shull; (3) “From the viewpoint of
the morphologist,’ R. A. Harper; (4) “From
the viewpoint of the bacteriologist and physi-
ologist,” Guilford B. Reed; (5) “From the
viewpoint of the pathologist,” E. C. Stakman.
The writers of these papers cooperated splen-
didly, both in division of subject matter and
in time of presentation. The results seem to
confirm the expressed belief of many botanists
SCIENCE

that a symposium of general interest, making
appeal to workers in all the principal fields,
is well worth while.
At the business session of Section G, John
T. Buchholz, of the University of Arkansas,
was elected to be a member of the section com-
mittee, his term of office to end January 1,
1926. Professor F. E. Lloyd of MeGill Uni-
versity, was selected as vice-president for See-
tion G for 1922.
Botanical Society of America.—tThis society
held sessions beginning Wednesday morning,
December 28, 1921, and continuing through
Friday. On Thursday afternoon the Myco-
logical Section held a joint session with the
American Phytopathological Society, and on
Thursday afternoon the Physiological Section
met in conjunction with the American Society
for Horticultural Science and the Ecological
Society of America. At the sessions of the
Botanical Society of America, eighty-seven
scientific contributions were read. The dinner
for all botanists was held on Friday evening.
After the dinner Dr. Marshall Howe read “A
Communieation from the Retiring Vice-presi-
dent,’ Dr. N. L. Britton.
American Phytopathological Society.—Ses-
sions of this society were begun on Wednes-
day morning, December 28, and continued
until Saturday morning. At the business ses-
sions of this society the following officers were
elected: President, E. C. Stakman, University
of Minnesota, St. Paul, Minn.; vice-president,
N. J. Giddings, University of West Virginia,
Morgantown, W. Va.; secretary and treasurer,
G. R. Lyman, Bureau of Plant Industry,
Washington, D. C. One hundred and seven
scientific contributions were read during the
sessions. The Phytopathologists’ dinner was
held on Thursday evening, the dinner being
followed by a diseussion of important topies,
and a short business session.
Board of Control of Botanical Abstracts.—
Business meetings of the Board of Control
were held on Tuesday, Wednesday and Thurs-
day. During these meetings various matters
were given attention including the election of
editors and various considerations in connec-
tion with the publication, financial support,
and cireulation of Botanical Abstracts.

SECTION I—PSYCHOLOGY
THE meeting of Section I (Psychology) at
Toronto was a very successful one. Although
the affiliated society was meeting elsewhere, a
considerable number of American psychologists
attended the sessions, and to these were added
several Canadian psychologists and a good
many professional men and women who are
interested in psychology from the point of
view of its practical applications to education,
business, criminology and related fields. The
program was enriched by contributions from
a number of men who represented these inter-
ests. The discussion of the papers was lively
and in some sessions had to be limited for lack
of time. The attendance at the meetings aver-
aged about 25 and reached 125 at one session.
As is usual, there was at the Toronto meet-
ing an intimate relation between the sessions
of Sections I and Q (Education). Sessions
were held conveniently in the same building,
and two were joint sessions. The papers in
these sessions dealt with mental tests or with
psychological studies in education. There was
apparent in the discussions of mental tests a
disposition to examine somewhat more critically
the conclusions to be drawn from the results
of mental tests than has prevailed in the past.
Of the other papers special mention may be
made of one by Professor Thorndike in which
he distinguished two types of equation—the
equation for solution and the equation which
expresses relationship—and advised that spe-
cial care be taken to avoid confusion between
the two.
The first session was devoted to general
papers. Professor Dale discussed the place of
psychology in university curricula, emphasiz-
ing the need of giving it reality by relating it
to the practical problems of life. Professors
Brett and Pillsbury discussed a number of the
important issues on which modern psycholo-
gists differ, and Professor Weiss discussed

[Von. LV, No. 1430
variability in behavior as a basis of social
interaction.
One morning session was devoted to applied
psychology. The problems in this field were
discussed from the point of view of employ-
ment relations, of job analysis, and of dealing
with the handicapped in occupation, by Mr.
George W. Allen, Professor EH. K. Strong, Jr.,
and Mr. Norman L. Burnett, respectively. Dr.
Alfred E. Lavell, chief parole officer of On-
tario, described the beneficial effects of super-
vised employment upon paroled prisoners.
The last session opened with two general
papers on mental tests and their significance.
Professor William D. Tait argued that educa-
tion should be highly selective and adapted to
intellectual capacity. Dr. R. M. Yerkes em-
phasized the need of other types of mental
examination in addition to intelligence tests.
The results of psychiatric and _ intellectual
examination of Illinois prisoners were pre-
sented by Dr. Herman M. Adler. In agree-
ment with the results of an Ohio study, his
examination showed that prisoners are not a
select group intellectually. He indicated, how-
ever, that they do exhibit anomalies of behavior.
Psychiatry in the publie schools was discussed
by Dr. Eric K. Clarke. The full address will appear in the Philadel-
phia Public Ledger for Sunday, June 11.

tion. When other features of plant growth
were investigated some effects of cultivation,
other than moisture, were brought out.
The recent controversy between Dr. Jerome
Alexander and Mr. L. 8S. Frierson in the Sep-
tember 2, 1921, the February 10 and March 24,
1922, issues of Science has been interesting.
One of these writers accepts the general view
that cultivation of the surface of the soil con-
serves soil moisture by preventing surface evap-
oration, while the other does not believe that
this is in accord with engineering experience.
If our work had shown that, in cultivation, we
were dealing with a moisture factor alone, the
writer might agree with one of these two men
without into the speecifie conditions
under which the data were obtained. Our work
has shown that cultivation changes the com-
position of the soil solution and has an effect
on the water requirements of the plants grown.
going
The Journal of Industrial and Engineering
Chemistry for March, 1922, Vol. 14, No. 3,
has-the following in an article by the writer in
discussing a composition basis for the water
requirements of plants: “There is a common
saying, cultivate to conserve soil moisture and
you will have larger crops. The author be-
lieves that cultivation lets air down into the
soil, thereby increasing bacterial activities
which in turn cause the plants to get more
food and grow larger on less moisture, would
be nearer the truth. Experiments are reported
where fertilization has decreased the. water
requirements of plants over one half, when
expressed as the amount of water necessary
to produce one unit weight of plant.
In the field experiments we had plants grow-
ing well, with cultivation, when on the same
soil without cultivation, lack of water in the
soil was hindering plant growth. It was easy
to say that these were the results of cultivation
in conserving soil moisture but to find out how
the mulch conserved the soil moisture was a
problem for intensive study. The evident facts
were that the well cultivated crops were not
suffering from lack of water in the period of
dry weather.
It was found that the soil having the water
reserve had a higher concentration of plant
food and the plants growing in this soil con-
JUNE 9, 1922]
tained larger quantities of the plant food
elements. Plants of the same species are
known to vary in analysis and plants of dif-
ferent analyses in our experiments were found
to have different water requirements. It ap-
pears that if the soil solution is weak the plant
transpires more water in its attempt to make a
normal growth. The larger number of stomata
on the leaves of plants with high water re-
quirements substantiate this.
The results of cultivation are a different
plant growing in a different soil and requiring
less water per unit of weight.
In the spring the soils of the humid regions
of the United States contain plenty of water
and it is general observation that the results
of cultivation (higher moisture in the, soil) do
not show up until periods of dry weather come.
In the fall there is again plenty of water,
under all systems of soil management. It is
the author’s belief, based on experimental
results, that proper cultivation throughout the
season will allow the plants growing on good
soils to make their growth on enough less mois-
ture (early in the season) so that they can
keep on growing during periods of dry
weather on what may be called an aceumula-
tive moisture reserve.
The summary of the water requirement paper
in the Industrial Journal follows:
The results of field and greenhouse experimeuts
recorded in the following paper indicate that fer-
tilization of a soil which responds to direct or
indirect fertilizer treatment allows the plants to
make their growth on a smaller amount of water
and to have a different composition from what
they otherwise would.
The same effect is produced by cultivation,
which by opening up the soil increases bacterial
activity, which in turn gives increased concentra-
tion of the soil solution.
Proper fertilization and cultivation minimize
dangers to crops from drought injury in humid
regions of the United States by having the plant
go into the drought period with an accumulative
reserve of soil moisture.
This work opens up the study of fertilization
_from the basis of water requirement.

THE COPPER ESKIMOS
I RETURNED in the autumn of 1921 from six
consecutive years in the arctic regions. Three
of these were spent for purposes of geographie
and ethnographic study among the Copper Es-
kimos. I am now engaged upon writing up the
results of that investigation, but, as there is no
prospect of getting this printed before at least
one year, I want to make a preliminary an-
nouncement about certain results of my archeo-
logical and ethnological work.
Previous to 1912, the eastern known limit of
pottery among the Eskimos was Point Barrow
(cf. Murdock on the Point Barrow Eskimos).
Stefansson’s work of the years 1908-12 ex-
tended the known pottery area eastward some
six or seven hundred miles to Cape Parry, and
he found it there in the most ancient ruins,
indicating that pottery has been used by the
Eskimos for centuries and perhaps by the ear-
liest Eskimos who occupied that country.
Jenness has published the results of his two
years spent among the Copper Eskimos (Re-
port of the Canadian Arctic Expedition, 1913-
1918, -Vol. XII, published by the Department
of the Naval Service, Ottawa). In this he does
not mention pottery, which would indicate that
he found none to the east of Cape Parry. In
excavating various sites I have found pottery
fragments as far east as Point Agiak, just west
of Gray’s Bay, or about 80 miles east of the
Coppermine. This extends the known pottery
territory some 400 miles east beyond Stefans-
son’s results. Like Stefansson, I found the
pottery deep down, indicating that it had been
in use probably several centuries ago and per-
haps by the earliest Eskimos. The implements
associated with the pottery were of undoubted
Eskimo type.
Previous to 1910 houses of earth and wood
had not been reported from the western arctic
coast of Canada further east than Pierce Point.
Stefansson in his journeys along the coast the
spring of 1910 and again the summer of 1911
found the ruins of earth and wood houses as
far east as one/mile east of Crocker River.
In an appendix to Jenness’ report (cited above)
we learn that since his return in 1916 Captain
Joseph Bernard, who entered the Copper Es-
612
kimo country only a few months after Stefans-
son in 1910 (see My Life with the Eskimo, by
V. Stefansson, p. 258) has reported finding the
ruins of houses made of earth and wood on
southwestern Victoria Island. Jenness concludes
that this is a sporadic occurrence and attributes
it to a visit from the western Eskimos. Thus
Jenness evidently assumes that the people from
whom the present Copper Eskimos are de-
scended never had wooden houses.
In 1919 A. H. Anderson found earth and
wood houses on Cape Krusenstern and at vari-
ous places in Coronation Gulf. Lastly, I have
(during the years of 1917-1921) found ruins of
the type of earth and wood houses used in
Alaska and the Mackenzie River at intervals
along the shores of Coronation Gulf to the
above-mentioned Point Agiak. I also have ac-
eurate Hskimo information about the location
of a village of the same type on the coast of
Melville Sound due south of Kent Peninsula.
Thus we find houses of wood and earth as far
east as West Longitude 107°. For reasons
which I cannot go into here, I consider it likely
that future investigations will show a continua-
tion of this chain of ancient earth and wood
dwellings most if not all the way to Atlantic
and Hudson Bay waters.
As it seems to differ from that of some other
investigators, I want to record here the opinion
(based on my studies in Coronation Gulf) that
the present Copper Eskimos, who have no. pot-
tery and use no wooden houses, are in the main
at least descendants of the earlier inhabitants
who used pottery and wooden houses. My view
is that the present culture (characterized in
part by stone pots instead of pottery, and
snowhouses instead of wooden houses) has been
gradually evolved partly because the previous
culture was never as well suited to the local
conditions as the present, and partly because
the local conditions have changed somewhat.
One important feature of the change has been
the lessening importance and eventual abandon-
ment of whaling. My work shows that whaling
was formerly practiced in certain parts at
least of the Copper Eskimo country.

SCIENTIFIC EVENTS
THE BRITISH INSTITUTE OF PHYSICS
At the annual general meeting of the British
Institute of Physics, held on May 23 in the
rooms of The Royal Society, the following
officers and board were elected to serve for the
year beginning October 1, 1922: President,
Sir J. J. Thomson; past president, Sir R. T.
Glazebrook; vice-presidents, Sir Charles Par-
sons, Professor W. Eecles, Professor C. H.
Lees, Mr. C. C. Paterson; non-official members
of the board, Dr. R. 8. Clay, Professor C. L.
Forteseue, Professor A. Gray, Major E. O.
Henrici, Sir J. E. Petavel, Dr. E. H. Rayner,
Sir Napier Shaw, Mr. R. 8. Whipple; repre-
sentatives of participating societies—Physical

Faraday Society, Mr. W. R. Cooper; Optical
Society, Mr. John Guild; Rontgen Society, Dr.
G. W. C. Kaye; Royal Microscopical Society,
Mr. J. E. Barnard.
The annual report stated that there were 408
members of the institute at the end of the year,
of whom 258 were fellows.
The institute is watching the possibility of
establishing a central library for physics,
although the financial difficulties in the way of
its realization are stated to be considerable.
In the course of his presidential address Sir
J. J. Thomson, after dealing with the project
to establish a Journal of Scientific Instruments,
spoke of the present depression in industry,
but he made the reassuring statement that out
of 67 students who graduated with distinction
in physies and chemistry in 1921, 46 had ob-
tained suitable positions, while 14 were doing
research work. He hoped that the series of
lectures on physies in industry which had been
established would act to some extent as “re-
fresher courses.”
Speaking of the difficulties which the safe-
guarding of industries act had, in many
instances, placed in the way of research, he
characterized research itself as a “key indus-
try’ and he hoped that the government would
put every facility in the way of research
workers being able to obtain without delay the
apparatus they required.

THE RADIO SERVICE OF THE UNIVERSITY
OF WISCONSIN
EXTENSIVE new radiophone broadcasting
services were started by Station WHA, Univer-
sity of Wisconsin, on Monday, May 29, to be
continued throughout the summer and until
further notice.
Noonday radio broadeasts, consisting of five-
or ten-minute talks, will be sent at 1:05 p.m.
five days each week. These talks will be by
members of the university faculty and in many
eases will be delivered in person. They will be
on subjects of general interest and will enable
the public to hear university men talking on
subjects on which they are authorities.
A Tuesday night university radiophone lec-
ture course was started on May 30. At 8
o’clock every Tuesday night a university pro-
fessor will broadcast a twenty-minute lecture
on a subject of general interest. The first lec-
ture was a Memorial Day address delivered by
Professor W. F. Lorenz, major in the Thirty-
second Division, now actively associated with
the rehabilitation of disabled soldiers.
These new broadcasting services will not
affect the present services of University Sta-
tion WHA. It will continue the Friday night
musical appreciation course and radiophone
news service of the University Press Bureau, as
well as the daily market and weather reports
and services for amateurs.
The schedules of each week in the new lee-
ture courses will be sent to the newspapers in
advance. The program of the first week was
as follows:
1:05 Monday, May 29—‘‘The
Spirit,’’ by Professor E. H. Gardner.
1:05 Tuesday, May 30—An address by Presi-
dent E. A. Birge.
8:00 Tuesday, May 30—Memorial Day address
by Major Lorenz.
1:05 Wednesday, May 31—‘‘The
Clinie,’’ by Dr. J. S. Evans, director.
1:05 Thursday, June 1—‘‘Spring Sports’’ by a
member of university athletic department.
1:05 Friday, June 2—Readings by Dean F. W.

SCIENTIFIC EXHIBIT AT THE MEETING OF
THE AMERICAN MEDICAL ASSOCIATION
THE Journal of the American Medical Asso-
eiation states that this year the exhibit exceeded
SCIENCE
613
expectations in the number of exhibitors, while
the quality of the work shown was of a high
order. The setting for the exhibit was much
better than usual; the booths were of pleasing
appearance, painted green with white trim-
mings, and with overhanging plants. As has
been customary, the exhibit was classified. The
educational section included a number of ex-
hibits of charitable or semi-public organizations.
Probably the pathologie section was the most
interesting. Here one found such exhibits as
that on pelykography (Dr. Reuben Peterson,
University of Michigan); studies on ringworm
fungi (Mr. Robert Hodges, University of Ala-
bama); specimens of flagellate protozoa under
well illuminated microscopes (Dr. Kenneth
Lynch, Dallas, Texas); work on the bile factor
in pancreatitis (Drs. F. C. Mann and A. S.
Giordano, Mayo Clinic); pathologie
specimens and comparative Roentgen ray rec-
ords (Dr. Eugene Opie, St. Louis), and the
excellent work on renal circulation (Depart-
ment of Urology, University of California).
The most striking exhibit in the surgical sec-
tion was the display of plaster casts and com-
parative photographs dealing with facial sur-
gery; one half of the exhibit was devoted to
civilian work, the other half to war reconstrue-
tion (Dr. Vilray P. Blair, St. Louis). In the
medical section the diagnosis of syphilis from
the laboratory point of view was well presented
(Dr. Loyd Thompson, Hot Springs, Ark.) ; in
another booth was an interesting exhibit of
pigeons illustrating vestibular tremors (Dr.
C. lL. Woolsey, Boston). In addition to the
foregoing were a large number of electrocardio-
graphic exhibits. The total number of ex-
hibitions was 48, thus divided: educational, 12;
pathologic, 10; surgical, 6; medical, 6; electro-
cardiographic, 14. On the stage of the audi-
torium the work of the various councils and the
chemical laboratory of the American Medical
Association was shown.
The committee on awards, consisting of Drs.
W. B. Cannon, George Dock and Louis B.
Wilson, made the following recommendations:
The Gold Medal to Drs. Frank Hinman, D. M.
Morison, A. E. Belt and R. K. Lee-Brown, of the
University of California Medical School, for a
study of renal circulation.
The Silver Medal to Mr. Robert A. Hodges,
gross

University of Alabama, for a study of certain
culture-medium characteristics of ringworm fungi.
The Certificate of Merit to Dr. Vilray Papin
Blair, St. Louis, for an exhibit of photographs
and plaster casts showing various types of face
restoration.
The committee also desires to give honorable
mention to the following exhibitors: :
Dr. K. M. Lynch, Dallas, Texas, for a study of
the cultivation and differentiation of flagellate
protozoa.
Drs. F. C. Mann and Alfred S. Giordano, Mayo
Foundation, Rochester, Minn., for studies on the
bile factor in pancreatitis.
Dr. Eugene Opie, Washington University, St.
Louis, for a comparison of Roentgen ray records
and gross pathologic specimens.
Miss Elizabeth Green, Barnes Hospital, St.
Louis, for a demonstration of methods used in
distributing books in hospitals.
THE ROME MEETING OF THE INTERNA-
TIONAL GEODETIC AND GEOPHYSICAL
UNION
Some 300 delegates and guests attended the
meetings at Rome, May 2 to 10, of the Geo-
physical’ Union and of the Astronomical Union.
Every country belonging to the unions had sent
one or more representatives. There were be-
sides present representatives from other coun-
tries (the neutrals during the late war), which
have already joined the International Research
Council and are making preparations to join
one or more of the unions. The delegates from
the United States for geodesy and geophysics
were: Bowie, Bauer, Kimball, Littlehales
Reid and Washington. All of the sections re-
ported well-attended, successful and stimulating
meetings.
Among the special social features, abun-
dantly provided for by the Italian National
Committee, were the following:
May 2, 3 p.m.—Inaugural ceremony at the
Campidoglio, at which H.M. the King of Italy
was present.
May 4, 9 p.m.—Reception of the delegates at
the Campidoglio by the municipality of Rome.
May 8, 3 p.m.—Visit to the Palatino at the invi-
tation of the under-secretary of antiquities and
fine arts.
May 10, 1 p.m.—Visit to the Vatican and audi-
ence with the Pope.

DISCUSSION AND CORRESPOND-
ENCE
THE THERMEL
In the early literature thermoelectric gener-
ators were classified, regardless of use or char-
acter, according to the number of their parts,
into thermocouples and thermopiles. Some
years ago, when it became clear that thermoelec-
trie thermometers of widely differing complex-
ity were going to be frequently used inter-
changeably or in combination, it seemed desir-
able to have a single not too lengthy name for
them. The word ‘“thermoelement,”’ though not
fully satisfactory, seemed to be the only word
in use which would answer, and was accordingly
proposed, in a paper from this laboratory, as
a shorter synonym for thermoelectric thermom-
eter. Its rather wide adoption indicates that
the idea of a single short name for all ther-
moelectric thermometers is generally welcome,
but the somewhat equivocal term, thermoele-
ment, has been the means of some confusion.
Leading writers, even, have spoken of such
things as “multiple thermo-couples,” “ihermo-
couple elements,” “a multiple thermo-couple of
four elements.”
It therefore has seemed better to use the
modified form “thermel.” Logically, this may
be taken as an abbreviation either of “thermo-
element,” or of “thermoelectric thermometer,”
both now in use. It is a handier word, even,
than “thermometer” itself, and has received
considerable approval. Since there appears to
be, unfortunately, no authoritative body to
which new terms can be referred for acceptance
or rejection, we in this laboratory are taking
the responsibility of using thermel in our pub-
lieations, and recommend its general use. A
thermel, then, may be a single thermocouple, or
a multiple thermel or thermopile, containing
more than one couple. Its distinguishing
characteristic lies in being used for temperature
618
measurement. The term “thermocouple” may,
unmolested, preserve its original application to
a single couple only. The term “multiple
thermel” seems rather better than “thermopile”
since it classes its object with other thermels
or thermoelectric thermometers, whereas “ther-
mopile” is more commonly associated with eur-
rent generators, or with the special thermom-
etry of radiation measurement.

SOLAR ENERGY
“Creative Chemistry,” by Edwin E. Slosson,
M.S., Ph.D. (The Century Company), is a
most interesting account of the astonishing
number of important practical uses, in industry
and war, of applied chemical science. For the
benefit, apparently, of readers who are not edu-
cated chemists, or physicists, it makes occa-
sional statements of pure science. One of
these has the effect to revive the inquiry
whether such statements ought not to refer to
the observations or experiments on which they
are based, unless readily available elsewhere.
It reads: “Solidified Sunshine. All life and all
that life accomplishes depend upon the supply
of solar energy stored in the food.’’ This is,
in substance, but a repetition from prior pub-
licists, many of them distinguished.
For example, Dr. Schuchert says: “Plants
convert the kinetic energy of sunlight into the
potential chemical energy of foodstuffs. Ani-
mals convert the potential chemical energy of
foodstuffs into the kinetic energy of locomo-
tion.” And Dr. Soddy says: “Energy may
sleep indefinitely .... In the potential form
in coal, it has persisted for untold ages. Once
released, heat is the sole ultimate product.”
A quite extensive search has failed to find,
in any literature, the account of an observation
or experiment as leading to such conclusion.
An elementary item of chemical teaching is that
the sun’s rays convert (approximately) 44
weight units of the comparatively inactive gas,
carbon dioxide, into 32 like units of the uni-
versally active gas, oxygen, and 12 lke units
of carbon, ultimately a solid possessing no

readily perceptible activity and incapable even
of combination without the application of ex-
ternal heat. It is not easy for a non-specialist
to believe, without evidence, that the energy of
the sun’s rays which decomposed the 44 units
of the dioxide, adhered to the 12 units of ear-
bon, and perhaps fell asleep there, while no
noticeable amount went into the activity of the
32 units of oxygen.

SCIENTIFIC WORK IN RUSSIA
ScreNTIFIC men may be interested in the
following letter that I have received from Dr.
Th. Fjeldstrup, of the Russian Museum at
Petrograd:
The effect the arrival of this letter will have
produced on you is probably that of something
dropping into your hands out of space.
It is of no use speculating on the possible ideas
you had as regards my fate, no more than on the
picture you Americans have imagined to your-
selves of the state of Russia’s home life to-day,
since they are based on scraps of news, often
defective, given in papers or obtained otherwise—
our two worlds have been separated too long and
too completely in their intellectual life to know
much of each other.
Often and often did I feel tempted to recom-
mence correspondence with- you, but the prospect
of being read a year or so after having written, if
at all, cut short all attempts of the kind. I have
better hopes now and therefore I permit myself
to remind you of my existence and send you my
best greetings.
After -an absence of almost full four years
(since end of February, 1918) I returned to
Petrograd two months ago. Throughout this long
period I have had various occupations, not always
agreeable to my inclinations, but this was un-
avoidable, nor could one expect to be allowed to
The scene les beyond the Ural Mts.
I do not intend to waste your time by giving a
detailed description of my doings in the run of
these years. I shall only dwell for a moment on
some facts that might interest you.
The summer of 1920 I spent as a member of a
scientific research party sent out by the Univer-
sity of Tomsk in the region that you paid a short
visit to before joining me in Verchni-Udinsk, viz.,
the Minusinsk region. The city of Minusinsk and
its museum I visited twice. The curator of the
museum is a new man since you saw it, but the

state in which the archeologic collections are is
exactly the same, I suppose—no worse. Mr.
Kozevnikoff (the curator) is a zoologist.
Part of my time was dedicated to work among
the natives (folklore and collections) and part to
excavation of the Bronze age mounds (kurgans)
under the directions of Professor 8S. Rudenko—
Professor Volkov’s pupil and his successor at the
University of Petrograd now. (By the way, I
suppose you have heard that Volkov, Radloff,
Princes Oukhtomsky—son and his father quite re-
eently—are no more).
Last summer we spent a couple of months with
the Kirghiz of the Turgai region, ‘‘ taking stock,’’
so to say, of possibilities for work on a larger
scale, if circumstances permit. Anthropometric
measurements (800 individuals) and 2-3 Neolithic
stations were among the results.
Next spring and summer I may return to the
Kirghiz—they are in my department at the Rus-
sian Museum with which I am now scientifically
connected.
In spite of unfavorable conditions and difficul-
ties scientific work in Russia has not ceased to
progress, and scientists of all classes continue
their field and home studies with all the energy
they are capable of. There is one great privation
of which we are acutely sensible, and that is—
book famine. We are so thoroughly isolated that
scarcely any literary news comes filtering through
the frontier. The appearance of a copy of some
comparatively fresh publication from the outside
world becomes known immediately to the circles
interested in its subject, is weleomed with joy
and every one tries to get at the book and have
it lent to him for a time; individual book, peri-
odicals, pamphlets, all one.
Without knowing what goes on elsewhere in
science one feels like going about with plugs of
cotton wool in one’s ears.
Now, Professor Rudenko, with whom I am on
very friendly terms, begs me to put a businesslike
question to you in a quite unofficial way.
During your stay in Petrograd in 1912, you
spoke to Professor Volkov and Pr. Oukhtomsky of
the desirability of establishing here a bureau for
the exploration of the northeastern portions of
Siberia by Russians with American cooperation.
Having this idea of yours in mind, Rudenko, who is
now the curator of the Siberian Department and is
proposed to the post of director of the Russ Mu-
seum,! would like to know whether you still think
this project practicable, and if so would your or any

other institution wish to participate in the realiza-
tion of a series of expeditions to the Far East
(Mongolia, the Amur region, Central Siberia)
which would make it possessor of scientific re-
sults and collections. The Russ Museum has a suffi-
cient number of well qualified explorers. The
question of fitting them out for the field may
prove difficult in some respects; but such diffi-
culties would be easily allayed if the work were
planned on the principles of cooperation.

DOCTORATES IN AGRICULTURE
In Science, Vol. LV, page 271, appears an
article by Callie Hull and Clarence J. West
on “Doctorates conferred in the sciences by
American universities in 1921.” Three theses
are listed for the subject of agriculture. There
are in universities, generally, no departments
of agriculture, but colleges of agriculture con-
sisting of departments using methods of their
own development and methods of the different
sciences in studying agricultural problems.
Students being trained for work in such de-
partments are listed in the article mentioned as
having done their work primarily in bacteri-
ology, botany, chemistry and zoology, perhaps
because the titles indicate that the methods of
these sciences were used. The fact remains,
however, that they were preparing to study
agricultural problems. Thus, at Cornell Uni-
versity alone, at least fifteen of the persons
named under these four sciences were working
in the College of Agriculture, preparing to
study agricultural problems. And from the
titles, I can be certain of at least four such
men for other universities.
If no names had been listed under the sub-
ject of agriculture, no harm could have been
done, but to list a subject of agriculture with
only three names, it seems to me, might leave
the impression that, with the great develop-
ment of the agricultural colleges, there is very
little tendeney for workers to secure the train-
ing necessary to attack problems in an effective
way. I believe that every one acquainted with
the conditions in the colleges is convinced that
there is a very hopeful development of gradu-
ate work and that the number of young men
who are securing sound training for effective
620
work in agricultural subjects gives promise of
very sound and rapid growth in agricultural
research.

THE WRITING OF POPULAR SCIENCE
To tue Eprror or Science: The letters of
Dr. Dorsey and Dr. Slosson, which have ap-
peared in Science, raise questions that have
perplexed both scientists and editors of popular
scientific magazines. Neither Dr. Dorsey nor
Dr. Slosson, in my opinion, has struck at the
root of the matter.
So long as the standards of American jour-
nalism are what they are, it will be difficult to
enlist the whole-hearted cooperation of scien-
tifie men in popularizing the results of their
researches. A distinguished biologist put the
matter thus to me a few years ago: “We do not
mind being popularized, but we do mind being
made ridiculous!”
And there we have the whole truth in a
nut-shell. Consider these facts which have come
under my notice:
In the basement of the Bureau of Standards
is an electric furnace used for conducting ex-
periments at high temperatures. A Washing-
ton reporter, in quest of good red journalistic
meat, was permitted to see that furnace in
operation. On the following day there ap-
peared an article from his pen in a Washington
newspaper under the title, “Bureau of Stand-
ards Has Little Hell in Basement.” Is it any
wonder that the men in the Bureau of Stand-
ards look at him askance now?
During the days when Halley’s comet was
the subject of almost daily newspaper articles,
about twenty Chicago reporters camped on the
grounds of the Yerkes Observatory. Fearing
complete misrepresentation of the work that
they were doing, the members of the observa-
tory staff granted no interviews. Finally, one
ingenious reporter suggested that he be per-
mitted to photograph the entire staff on the
steps of the observatory. Inasmuch as all the
reporters had been treated rather haughtily, it
seemed as if this harmless request might be
granted. Accordingly, the staff posed. Two
days later, there appeared in a Chicago news-
SCIENCE
[Vou. LV, No. 1432
paper a photograph of one of the astronomers.
—a distinguished telescopic observer—seated at
the eye piece of the huge Yerkes refractor, but
in a position outrageously absurd. His photo-
graph had been cut out of that made on the
observatory steps, pasted upon a lifeless pic-
ture of the refractor, and the whole reproduced,
with results that astonished every astronomical
observer who saw the newspaper. The observa-
tory staff was kept busy explaining to its col-
leagues all over the country how this absurdity
was perpetrated.
Washington scientists surely have not for-
gotten the great injustice done to Samuel P.
Langley at the time when his historically im-
portant experiments with his man-carrying air-
plane were conducted. If ever a scientist’s life
was embittered and shortened by gross news-
paper misrepresentation, it was Langley’s.
Our newspapers and magazines are right in
demanding what they. call “human interest.” It
is what science does for mankind that is inter-
esting. The best popularizers of science have
always been humanly interesting—particularly
the men who have had theories to propound
which were not readily accepted by their col-
leagues.
The campaign waged by Darwin and his col-
leagues was a conspicuous example of sound
popularization. But our newspapers and mag-
azines ride human interest too hard. The one
thing that seemed to strike our reporters about
Einstein was the fact that he smoked a pipe
and that his hair was disheveled. At the mo-
ment, I do not recall more than two articles on
Einstein in the newspapers that pointed out
the tremendous practical significance of his
theory of relativity—the fact that chemists,
physicists, engineers and astronomers must
henceforth reckon with time, space and motion
in a new way. What Edison eats for breakfast
seems to be of more importance than what
Edison has actually achieved. So long as our
newspapers publish simply gossip and the news
of death and destruction, we have little to hope
from them. If anyone were to write a history
of the United States one hundred years hence,
with no other information before him than that
contained in current newspapers, he would
inevitably draw the conclusion that Americans
of our day led scandalous private lives and
JUNE 9, 1922]
were savagely addicted to killing one another.
Curiously enough, only the advertisements
would save him from presenting an utterly
distorted picture of present day life and
manners.
Since these are the editorial standards of the
day, is it any wonder that scientists hold aloof
from the reporter? Is it any wonder that they
do not wish to be made ridiculous?
In Europe it is otherwise. I have never had
any difficulty in securing whole-hearted co-
operation from English, French and German
scientists. They send their portraits on re-
quest—something that American scientists hesi-
tate to do. They write delightful scientific
feuilletons, many of them models of simplicity
and clarity. They recognize their journalistic
obligation to the public at large. But when
they come to this country, they soon learn the
wisdom of withdrawing into their shells.
The newspaper and magazine editor con-
stantly uses the stock argument that he “gives
the public what it wants.” But does he really
know what the public wants? Would any
magazine or newspaper editor have predicted
that Wells’ Outlines of History or Van Loon’s
Story of Mankind would have sold in editions
of one hundred thousand and more?
The Saturday Evening Post, with a cireula-
tion of over two million, publishes articles on
economies and industry which are, in the main,
excellent examples of what the popularization
of technical subjects should be. It has its
standards of human interest, but it does not
forget that the facts, simply, humanly, and
interestingly presented are “what the public
wants.”
It is possible that the schools of journalism
which have been established in various parts of
the country may bring about a reformation of
editorial standards through their graduates. Not
much is hoped for from the publishers them-
selves.
WALDEMAR KAEMPFFERT
Mr. Stosson’s indictment of American scien-
tists, in your issue of May 5, for their failure
to write interestingly and attractively about
their work is all too true. As a teacher of
English, I have observed the same failure
throughout our universities. Among both fac-
SCIENCE
621
- ulty and students an opinion prevails that
there are but two general ways of writing:
a so-called literary and polished style fit only
for esthetes and poets; and a crude, inchoate
style that marks the profound researcher and
busy technician. The scientific man generally
thinks that he hasn’t time to “polish” and
“adorn” his sentences; therefore he slips into
the slovenly jargon that he sees is customary
among his colleagues. He fails to notice that
there is a middle ground of simple, clear
English that can be made interesting and
attractive without his becoming a poet or an
esthete. Mr. Slosson’s English is an example.
Another example of a scientific man who taught
himself to write excellent English was Pro-
fessor John W. Draper, of New York Univer-
sity. His volume of “Scientific Memoirs” is a
model of clear, incisive prose.
Professor Draper won the Rumford medals
and was the first president of the American
Chemical Society. But look at the accounts of.
chemical research as published to-day, and see
what they have become from the point of view
of English or readableness. Look at the tire-
some, too-modest statements, phrased in pas-
sives and circumlocutions to avoid saying “I”
or “me.” Pick a sentence at random and try
to tell what it means without reading it several
times. Such a style is supposed to indicate
the scientific, objective researcher. The awk-
ward sentences and confused transitions are
supposed to connote the profound scholar
intent on his specialty. The curious thing is
that many chemists can write well if they
choose. But when they begin to explain their
work, they drop into professional jargon, which
disguises their real ability. Such jargon is the
custom. It makes all the articles alike, looks
technical, dulls the interest, eliminates the per-
sonal element, and discourages discussion.
Mr. Slosson hints that he would like to see

To tHe Eprror or Scrmmnce: There is one
point in Dr. Allen’s letter of April 28 that I
think will bear further emphasis. As he points
out, most editors will print sound scientific
“stuff? which they ean get for nothing. But
they won't pay a living wage to the man who
writes it.
I have been doing this sort of work, off and
on, for a quarter century. In fact, for some
years I actually supported myself—at about
the clerical level. Those were the days when
“the Old Man” edited McClure’s and cared
more for the permanent repute of his magazine
than for selling out any single issue. News-
paper work paid decently. One could oceasion-
ally make a short story of a scientific item.
Even the women’s publications used to buy
semi-scientific articles on diet and child train-
ing.
Now all this is past; I haven’t tried to sell
anything since the war. It takes about as long
to verify all the statements in one article as it
does to write another. The verification is a
labor of love, for which no editor will pay.
The writer with an unhampered imagination
can turn out stuff that the public prefers; and
he can do twice as much of it ina day. My old
market is absolutely dead. In the present day
market, I can compete neither with the men who
are selling their product, nor with those who
are giving it away.
Dr. Allen’s solution, I heartily agree, is for
the moment the only practical one—though I
doubt whether, in the long run, the public will
get much good out of anything that it isn’t
willing to pay for. Nevertheless, I cannot help
thinking that the condition which Drs. Allen
and Slosson:are trying to cure is only a symp-
tom, not the real disease. For the fact is that
the world just now is being simply drowned in
a vast wave of superstition, that is bringing in
every sort of pre-scientific opinion that the
nineteenth century thought disposed of for
good and all. My own town, for example,
makes education its leading industry. But our
public library has to buy books, just off the
press, on palmistry, handwriting, character
reading and fifty-seven other varieties of non-
sense; while, significantly, it owns no old vol-
umes on any such topies. Te current number

NOTES ON METEOROLOGY AND
CLIMATOLOGY
THE STREAMFLOW EXPERIMENT AT
WAGON WHEEL GAP, COLORADO
Stupents of hydrology have always had a
keen interest in the relation of run-off to the
forestation of watersheds, and there has been
much theorizing as to the probable relation.
But there are so many factors involved—evap-
oration, transpiration, interception, ete., these,
in turn, being influenced by the geological,
phenological, and meteorological character of
the watershed,—that it is difficult, if not im-
possible, to estimate correctly the degree of
influence of each. It has been the purpose of
the Forest Service and the Weather Bureau to
conduet an actual experiment in order to obtain
quantitative measures of these influences and,
in general, the response of streamflow to a
forested and denuded watershed. The site
selected for this large-scale experiment is near
the railroad station of Wagon Wheel Gap,
Colorado, the station having an elevation of
8,437 feet above sea-level. The plan was to
select two contiguous watersheds of similar
character, make extensive meteorological and
hydrological observations on each, and, after
the lapse of a certain number of years, denude
one watershed of its trees and continue ob-
servations for a sufficient number of years to
determine in what manner the streamflow is
influenced.
On June 30, 1919, an eight-year continuous
series of stream-flow observations and a nine-
year meteorological record had been obtained,
and, after a general survey of the results, it
was decided that the trees could properly be
removed from one watershed. The denudation
was completed in the autumn of 1920. - This,
therefore, marked the completion of the first
stage of the experiment. Observations are
being -continued, and will continue for several
JUNE 9, 1922]
years, but the report on the first stage has just
been published.t. The Forest Service is repre-
sented by Carlos G. Bates, silviculturist, and
the Weather Bureau by Professor A. J. Henry,
meteorologist, the reports representing joint
authorship.
While an effort was made to select water-
sheds of similar character, it is obvious that,
no matter how good the general agreement of
the main features, exact duplication was im-
possible. Watersheds A and B at Wagon
Wheel Gap, therefore, have certain character-
istics in which they are quite different. Through
these two small valleys flow tiny streams which
descend toward the Rio Grande. The streams
are approximately parallel in their lower por-
tions and flow, in a general direction, from
west to east. The area of the south watershed,
A, is 222.5 aeres and that of the north water-
shed, B, is 200.4 acres. The lower point of A
is 9,373 feet and the upper point 11,355 feet
above sea-level. Corresponding elevations for
B are 9,245 feet and 10,952 feet above sea-
level. These facts are not as significant, so
far as this study is concerned, as the fact that
watershed A is relatively long and narrow,
while B is short and fan-shaped. These char-
acteristics exert considerable influence upon
the rate of runoff, for, owing to the short,
steep, slopes of A, the flood crest arrives more
quickly than in B, but falls sooner, then comes
to a secondary maximum of longer duration,
because of the greater length of the watershed.
The flood at B exhibits no secondary maximum
because the water reaches the dam from all

parts of the watershed at approximately the
same time. Moreover, 4 and B lying in dif-
ferent directions, as explained above, involves
a difference in the rate of snow melting owing
to the different exposure of the slopes to the
sun; this has an effect upon the streamflow.
The geological character of the two watersheds
has been found to be the same. The trees con-
sist largely of Douglass fir, although there is a
considerable sprinkling of bristle-cone pine and
Englemann spruce, the distribution depending
upon the altitude, the exposure of the slope,
and the amount of rock in the soil. :
The observing equipment is of two kinds,
meteorological and hydrological. Six primary
meteorological stations were established at the
beginning of the experiment, one at the base
and one in the upper reaches of the streams,
and two in each of the valleys. The equipment
of these stations varies according to the topo-
graphic features in the vicinity; but, among
them are to be found maximum and minimum
thermometers, psychrometers, thermographs,
soil thermoscopes, hygrographs, anemometers,
raingages, and snow bins. ‘The headquarters
station is the most completely equipped, having
two standard barometers, and a triple register
for recording automatically wind direction and
speed, precipitation and sunshine. On A there
are 18 snowscales—graduated stakes 12 feet
high—and on B, 14 scales, the location of each
having been carefully selected so as to be rep-
resentative of the snowfall on a given acreage.
The hydrological equipment consists of a
dam in each stream so constructed as to make
the surface and subflow of the streams avail-
able for measurement. Back of the dams are
concrete basins in which continuous automatic
record of the waterstages is kept by a Friez
recorder. The instrumental record is checked
daily by a reading with the hook gage, the
latter being so accurate that several observers
do not differ more than 0.001 foot on a given
reading. . The dams at first had rectangular
weirs, but for these triangular weirs were later
substituted.
The following facts are shown by the nine
years of meteorological observations: (1) The
mean minima for identical periods and times
are slightly higher for slopes facing south than
for those facing north, but the greatest differ-
624
ence for any month does not exceed 1° F.
Comparing corresponding slopes of the two
watersheds, the mean temperature is substan-
tially the same. (2) Precipitation occurring
as rain is practically equal on both watersheds.
If the soil is saturated, as small a rain as 0.01
inch may cause the streamflow to respond; but
ordinarily rains of 0.10 inch or less in summer
merely replenish losses due to evaporation or
transpiration, and do not affect streamflow ap-
preciably. Most of the summer rains are not
in excess of 0.25 inch, hence it is seen that
summer rains are not, in general, of great
importance. (3) A little less than 50 per
cent. of the precipitation is snow, but it yields
more than half the runoff. The average depth
of snow per season is 113.3 inches. The maxi-
mum observed was 149.7 inches and the mini-
mum 80.7 inches.
Interesting features of the streamflow records
are: (1) Stream 4 rises more rapidly than B
and reaches a maximum sooner than B, but
before the flood has subsided a secondary max-
imum with a steadier flow may occur at A.
This feature, as mentioned above, is easily ex-
plained by topography. (2) Winter. and
autumn show very little diurnal variation of
streamflow; summer is more marked, with a
maximum in the early morning hours and a
minimum between 1 and 2 o’clock in the after-
noon; spring, however, with the great amount
of melting snow, has a pronounced diurnal
period owing to alternate freezing and thawing.
The amplitude of variation is greater at A than
at B, and the 4A maximum and minimum are
more pronounced. (3) An estimated disposi-
tion of 21.00 inches of precipitation, the aver-
age annual amount for eight years observations,
is shown for A as follows:

It is clear that the. objective of all these
studies is an accurate estimate of the relations
between the various factors on A and B in
order that, in the years following: denudation,
the conditions on A can be used as an index

to what would have occurred on B had denuda-
tion not been effected. It is only in this way
that the effect of the presence or absence of
trees can be ascertained. Much of the paper,
therefore, is devoted to these relations in too
great detail for abstracting. Thirteen “rules’’
are developed as statements of these relations
to be used in the later discussions. These con-
cern ratios of discharges in different periods
and at different times, time intervals between’
crests, probable height of crests, and the depo-
sition of silt. 4
This experiment is of great practical im-
portance with respect to hydrological prob-
lems—floods, irrigation, ete., and its outcome
will doubtless be watched with the greatest
interest by those who are concerned with these
problems.

SPECIAL ARTICLES
AN EARLY STAGE OF THE FREE-MARTIN
AND THE PARALLEL HISTORY OF
THE INTERSTITIAL CELLS
THe theory that the intersexual condition
of the free-martin depends upon hormones
secreted by interstitial cells of the testis of the
male twin and distributed by its blood to the
female :depends primarily upon the demon-
strated connection between fetal vascular
anastomosis and the intersexual condition of
the female twinned with a male calf, and see-
ondarily on comparative data. The time of
effective action of the male hormone has been
presumed to be very shortly after the beginning
of sex-differentiation in the embryo (Lillie,
17) owing to the known normal condition of
the embryonic membranes in such stages, which
renders vascular connection possible, and the
very profound nature of the effect. The earli-
est stage of the free-martin hitherto deseribed
s 7.5 em greatest length (Lille, 717; Chapin,
17). Sex-differentiation begins at approxi-
mately 2.5 em. The gap thus indicated in our
knowledge of this phenomenon is now largely
filled up by study of a free-martin of 3.75 em
greatest length, and of the complete history of
the interstitial cells of the testis and ovary
from 2.5 em throughout life.
me
JUNE 9, 1922]
In the 3.75 em free-martin the gonad is much
less than half the bulk of those of normal
males and females of corresponding age. The
germinal epithelium (cortex of ovary) is only
about one fifth the thickness of that of the
normal female of corresponding age and less
developed than a female of 3 cm _ greatest
length. The blood of the male has already
operated to inhibit growth of the entire gonad
and to stop the differentiation of the cortex.
The specific male sex-hormone is thus demon-
strably present in the blood at this stage.
Interstitial cells appear in the testis of the
normal calf embryo between the stages of 2.7
and 3 em greatest length. At the latter stage
they are identical in size and histological strue-
ture with those of later stages and the adult;
they have a continuous history up to adult age.
In the female, on the other hand, comparable
cells do not appear in the ovary until about the
time of birth.
The following conclusions may be drawn:
1. The appearance of interstitial cells in the
testis at the very time that a male hormone may
be demonstrated by its physiological effects
(free-martin) is strong evidence that these cells
secrete the sex-hormone.
2. The absence of such cells in the female
and the corresponding lack of effect of the
female blood on the male twin argue in the
same sense.
3. In the female of cattle sex-differentiation
before birth is apparently due to genetic factors
exclusively; in the male the genetic factors are
intensified by the production of a hormone.
The detailed data will be published shortly
by the authors separately, Mr. Bascom dealing
with the interstitial cells.

THE EFFECT OF ACID ON CILIARY ACTION
AS A CLASS EXERCISE IN pH
Tue effects of changes in hydrogen-ion con-
centration have received so much attention in
the recent literature that it has become desir-
able to incorporate some exercise into labora-
SCIENCE
625
tory courses in physiology which will illustrate
the principles by which the py, of a solution
is determined. For the majority of college
laboratories “gas chain” apparatus, potentio-
meters, ete., are out of the question for student
work. The colorimetric method, however, which
is very simple and sufficiently accurate for
general laboratory problems, can be used to
good effect at very little expense.
For our class in general physiology consist-
ing of some twenty students in their second
and third college years, we have outlined an
experiment on the stopping of ciliary move-
ment in the epithelium of the frog’s esophagus
by acid which has proved most successful. The
experiment is in the form of a problem, and
is stated thus: “Find the concentration of acid
which will stop ciliary action within approxi-
mately three minutes.” The students work in
pairs. A small bit of ciliated epithelium is
placed on a slide, and while one student ob-
serves this under the low power of the micro-
scope, the other places upon the tissue a few
drops of acid, and records the time. When the
concentration has been found which stops the
movement of cilia in three minutes, an indica-
tor is added in the correct proportion (Clark,
20, p. 40) and the py determined by matching
the resulting color with the appropriate color
in the color chart.
When acetic acid diluted with distilled water
was used with brom phenol blue as indicator,
the following answers were handed in by the
class :
Motion stopped in less than 2
2 groups of students.
Motion stopped in 3 min., p,, = 3.5, 6 groups of
students.
Motion stopped in 34% min., p,, = 3.6, 1 group of
students.
Motion stopped in 9 min., p,, = 3.8, 1 group of
students.
min., pj; = 3.4,
The agreement between these results is, we
think, very good for an ordinary class exercise.
It should be noted that ordinary distilled
water is decidedly acid, py = +£6.3, and that
cilia cease to beat in it within approximately
half an hour. In 0.7% NaCl, the beating con-
tinues for a day, and in Ringer’s solution for
three or four days at room temperature. For
626
_ purposes of strict accuracy, therefore, the acid
should be added to normal saline or Ringer’s
solution, but for class purposes the distilled
water will serve.
The experiment has been designed not only
to show the stopping of ciliary action at a
definite hydrogen-ion concentration, but also to
bring out the difference in effect between an
organic acid, such as acetic, and a mineral acid,
such as hydrochloric. In the latter case even
a concentration, py, — 2, thymol blue as indi-
eator, will not stop the beating of the cilia in
less than 15 minutes. The greater concentra-
tion of hydrogen-ion required for the mineral
acid than for the organic acid is of course cor-
related with the difference in rate of penetra-
tion of these acids into tissues.
Furthermore, in order to obtain comparable
results the pieces of epithelium must be from
corresponding regions of the frog. If the
tissue is taken from the more posterior levels,
i. e., from within the esophagus itself, where
the cilia are very long, it is found that the
beating continues for a longer time in a given
concentration of acid than in the pieces from
more anterior levels, 7. e., the back of the
mouth, where the cilia are very short. The ex-
periment therefore brings out the fact that sus-
ceptibility to acid decreases in passing from
anterior to posterior levels of the alimentary
tract.

The meetings were well attended, and among
the members present were mammalogists who
represented the leading institutions of the coun-
try, such as the United States National Mu-
seum,, the Bureau of the Biological Survey,
the Field Museum of Natural History, the
Museum of Comparative Zoology, the Academy
of Natural Sciences of Philadelphia, the
American Museum of Natural History and the
New York Zoological Society.
Among the many interesting papers that
were given before the mammalogists was the
“Symposium on the Anatomy and Relation-
ships of the Gorilla.” At this session the at-
tendance was probably greater than at any of
the others, and representatives of the press
were present to make the most of a subject in
which the publie is at present so keenly inter-
ested. The consensus of opinion as expressed
by the speakers in this symposium was that
the gorilla stands very high among the anthro-
poids in its relationship to man, and the evi-
_ dence presented, together with the detailed
descriptions of the man-like characters of the
anthropoids, set forth data for an argument
which the anti-evolutionists would have great
diffieulty to refute.
At the last of the meetings for the presenta-
tion of papers, the “Close of the Age of Mam-
mals” was given by Professor Henry Fairfield
Osborn and Mr. H. E. Anthony. Professor
Osborn took as his thesis the very rapid dis-
appearance of our mammalia, which leads to
the conclusion that the age of mammals will
come to a close at no very distant date. After
outlining the inception and the development of
the age of mammals, illustrating his points by
distributional maps, Professor Osborn stated
that this age had reached its greatest develop-
ment in the late Pliocene and early Pleistocene,
at which time the glacial periods began the
destruction which is receiving its final accelera-
tion to-day at the hands of man. Having
SCIENCE
627
brought this outline of the history of the age of
mammals down to the present day, Professor
Osborn was followed by Mr. Anthony, who
showed a chart of statistics and gave figures
on the great destruction of mammal life which
may be laid at the door of the fur trade. A
discussion of the papers followed, during
which Dr. W. T. Hornaday, the noted advocate
of wild life conservation, spoke at some length
upon the disappearance of present day mam-
mals and urged the great necessity of untiring
efforts to stave off complete extermination.
Further discussion was given by Dr. W. D.
Matthew, Dr. Wilfred H. Osgood, Dr. Charles
C. Adams and Dr. E. W. Nelson, all of whom
were inclined to believe that it was no exag-
geration to consider that the “Age of Mam-
mals” was rapidly coming to a close, and that
stringent measures are necessary to protect the
surviving members. Dr. Adams, who is direc-
tor of the Roosevelt Wild Life Forestry Exter-
mination Station at Syracuse, N. Y., main-
tained that the only hope lies in education, not
so much of the adult, as of the younger genera-
tion, and pointed out the advisability of estab-
lishing numbers of wild life preserves, so that
people might come to know the wild life of
their own region by visiting the local pre-
serves.
The mammalogists were the guests of the
American Museum at a luncheon on Tuesday,
May 16, and were guests of the New York
Zoological Society at luncheon on Thursday,
May 18.
The annual dinner was held the evening of
Wednesday, May 17, at the Hotel San Remo.
At the annual election of officers, all of those
holding office were re-elected.
At the close of the morning session of Thurs-
day, the members adjourned to the North
American Hall of the American Museum where,
by short exercises, the museum dedicated this
hall to the memory of the late Dr. J. A. Allen,
who was the society’s only honorary member.
The hall hereafter will be known as the J. A.
Allen Hall of North American Mammals.
President Henry Fairfield Osborn presided
and, on behalf of the trustees, made the dedica-
tion of the hall, which was accepted on behalf
of the Division of Zoology and Zoogeography
of the museum by Dr. F. M. Chapman. An
628
appreciation of Dr. Allen’s services to natural
history was given by Dr. E. W. Nelson, presi-
dent of the Society of Mammalogists.
At the close of the luncheon given by the
New York Zoological Society, the mammalo-
gists were taken for a private view of the new
halls of the National Collection of Heads and
Horns and a tour through the park under the
guidance of the officers of the Zoological So-
ciety.
PROGRESS IN ANIMAL PHOTOGRAPHY
The American Museum had planned for a
prize exhibition of photographs of mammals
to be held at the time of the meeting of the
American Society of Mammalogists. This ex-
hibition was opened to the public on May 15,
and judges for the exhibition were appointed
by President Nelson of the American Society
of Mammalogists at the first business meeting
of the society. The board of judges appointed
by Dr. Nelson was as follows: Dr. Wilfred H.
Osgood, chairman, Dr. Witmer Stone, Mr.
Charles R. Knight, Mr. James L. Clark and
Mr. H. E. Anthony.
The photographs were exhibited in the Hall
of Forestry on the first floor of the museum,
where they will remain on exhibition for a
month. Some 1,654 photographs were received
for this exhibition and there were 139 con-
tributers. Requests for photographs and con-
ditions of the contest had been drawn up and
submitted by an American Museum Committee
as follows: Mr. H. E. Anthony, chairman, Mr.
Herbert Lang, Dr. Robert Cushman Murphy
and Dr. G. Clyde Fischer, but the credit for the
very unusual and splendid display of photo-
graphs which was brought together must be
given to Mr. Herbert Lang, who worked day
and night to make the exhibition a success.
The unanimous opinion of the many who have
seen this exhibition has been that it is easily
the finest exhibition of mammal photographs
ever displayed in this country. So many un-
usual photographs were submitted that the
judges found it a difficult task to award the
prizes, but finally made the following selection:

JOEL A. ALLEN MEMORIAL
One of the most important measures taken
up by this meeting of the American Society of
Mammalogists was the formulation of plans
and the appointment of a committee for estab-
lishing a publication fund to be known as the
J. A. Allen Memorial Fund. This fund has
been set at $10,000, and the interest from this —
sum, when it has been properly invested, will
be used by the American Society of Mammalo-
gists for the publication of papers to consti-
tute a series of continually appearing memo-
vials to the late Drv. J. A. Allen. The com-
mittee appointed to raise this fund, and given
full powers for this purpose by the society is
as follows: Mr. Madison Grant, chairman,
President Henry Fairfield Osborn, Mr. Childs
Frick, Dr. George Bird Grinnell and Mr. H. E.

It is expected that friends of Dr. J. A. Allen,
mammalogists and of wild’ life
throughout the country will give their support
toward the raising of this fund, since natural
science has never had a more devoted student
than Dr. J. A. Allen, and the purposes for
which the fund will be devoted are outlined to
give the greatest possible encouragement to
students

For Demonstrating

The Transformer and Its Principles
Induction Motor
Two or Three Phase Alternating Current
The Rotary Converter Phenomena
._ This apparatus consists essentially of two fields which may be fitted with poles on which are wound
coils and these fields may have 2, 4, or 6 poles for direct current work or 3 or 6 poles for three phase
alternating current work.
A simple direct current armature is supplied for mounting in this field and with this armature may be
demonstrated a series or shunt wound motor or dynamo and all characteristics of direct current dynamo
electric machinery of either 2, 4, or 6 poles. This furnishes much valuable informaton regarding the con-
nections of the different poles, the direction of rotation, etc.
The aluminum cup for use in this magnetic field illustrates the principles of the closed circuit rotor
for induction motors. The reversal of one of the field coils shows reversal of direction of rotation and
other similar important principles may be shown.
The converter may be demonstrated by placing the armature which has slip rings on one side in the
field shown on the right and arranging the poles and connecting a battery so as to run it as a direct
current motor. The brushes underneath will collect alternating current and this may be used for ringing
bells and may be shown to be alternating by the use of meters.
The Synchronous motor may be shown by carefully increasing the frequency of the alternating cur-
rent generated by increasing the speed of the central handle and at the same time have the armature
connected to this alternating current and the field coils in the proper order connected to direct current.
The alternating current generator may be demonstrated by energizing the fields by direct current
and using the armature that has the slip rings on it.
One of these fields has two slots in it for holding a yoke on which are two concentric, removable
coils and with this may be shown all the principles of the transformer, as transformation ratio, etc.
When used for alternating current work, that part of the apparatus which is mounted on the center
of the base converts direct current into alternating current and there can be obtained either single phase,
two phase or three phase current.
By the use of the polyphase current, a rotating field may be produced, and by the use of the
mounted magnetic needle it may be shown how this needle is whirled around as the field rotates.
This set contains a minimum of parts but enables teaching practically every application’ of either
alternating or direct current, dynamo-electric power apparatus.
This outfit is complete with the two fields and the A. C. Generator mounted on a base and the follow-
ing parts: 6 field coils, 1 direct current armature, 1 direct current armature’ with slip rings, 1 mounted
magnetic needle, 1 aluminum cup rotor, 1 transformer yoke with both primary and secondary coils.

THE MAINTENANCE OF SCIENTIFIC
RESEARCH!
Broapty taken, the apparatus of prosecution
of research in this country is made up as fol-
lows: (1) Scientific and professional societies
and some institutions entirely privately sup-
ported; (2) universities and colleges, with their
scientific departments; (3) institutions, using
that term in the widest sense, directly subven-
tioned by the state, such for instance as the
Medical Research Council, the Development
Commission, and the Department of Scientific
and Industrial Research. Of these three ecate-
gories, the first named, the scientific societies
group, works without financial aid from the
state, apart from the small though extremely
useful two government grants distributed,
mainly to individual workers, through the
Royal Society. At the present time many of
the societies sorely need financial help to carry
on their labors, and some are absolutely at a
loss to know how to publish the scientific re-
sults that are brought to them. The second
category, the universities and colleges, depends
in part upon government aid. In the aggre-
gate of twenty-one institutions of university
yank, following Vice-Chancellor Adami’s fig-
ures, students’ fees and endowment provide
about 63.5 per cent. of the total income; for
the rest they are dependent on government
grant. The third category, as said, draws state-
support direct.
This triple system may seem a somewhat
haphazard and incoordinate assembly. Yet in
reality it is an organization with much solid-
arity,- and its coordination is becoming more
assumed. Its parts dovetail together. The first
group, the scientific and professional societies,
is provided with a medium of intercommuni¢a-

630
tion and ¢o-action, the Conjoint Board of Sci-
entific Societies. As to the separate categories
composing the triple system itself, they also
are in wide touch one with another. Between
the scientific and professional societies on one
hand and the universities on the other, contact
and inter-relation are secured by some degree
of free and rightful overlap, both as regards
general subject-matter of research and of their
personnel. Tinally, there is excellent contact
between both these categories and the third, the
state subventioned institutions. A special fea-
ture of the policy and administration of these
state organizations secures this, a feature which
makes the whole of this subject the more
cognate to the purview of our own society. To
exemplify I may turn, for instance, to the
Development Commission. Its program of
fishery research, avoiding the terms “pure” re-
search and “applied” research in view of the
possible implication that pure research does
not lead to practical result, directs research not
alone to the solving of particular economic
problems. It supports more especially what it
terms “free” research, investigation in this case
of the fundamental science of the sea and of
marine life.
Again, with the Advisory Council of Scien-
tific and Industrial Research, its program,
gradually defined during the past six years, is
laid down as having four main points: (1) the
encouragement of the individual research work-
er, particularly in pure science; (2) the organ-
ization of national industries into cooperative
research associations; (3) the direction and co-
ordination of research for national purposes,
and (4) the aiding of suitable researches under-
taken by scientific and professional societies
and organizations. It recruits researchers by
giving financial opportunity to promising stu-
dents to be trained in research, attaching them
to experienced researchers. In short, it ap-
prentices to research a number of selected
younger workers in universities, colleges and
other seattered throughout the
eountry.
So, similarly, the Medical Research Council.
Its seeretary, Sir Walter Fletcher, in an illum-
inating presidential address to Section I of the
British Association meeting this summer, said,
institutions
SCIENCE
[Vou. LV, No. 1433
speaking of the nexus between scientific re-
search and the progress of medicine, “It is the
accumulating knowledge of the basal laws of
life and of the living organism to which alone
we can look for the sure establishment either of
the study of disease or of the applied sciences
of medicine.”
It is evident, therefore, that, with a poliev
based on such principles as these, the third
category in the triple system constituting the
organization for scientific research in this
country is one which has common aim and solid
touch with both the others, the universities and
the scientific and professional societies. One
sees in short that the organization which has
come into existence and is maintaining scien-
tific research in this country is a real organiza-
tion. It did not spring fully equipped from
the head of Zeus. It has grown up rather
than been planned. In that respect it is an
organization essentially British, and it seems
qualified to do its work for the country well.
We hear of adventures, political and other, the
offspring of the day. But these were no adven-
tures, these, to my mind, welcome, long-overdue
steps forward by the state toward the succor
of science and its welfare, steps that help to
strengthen and consolidate the organization
for research by such adjuncts as the Medical
Research Council and the Department of Scien-
tific and Industrial Research. One of the
strengths of this organization that has arisen
is, In my view, that it interlocks with the edu-
cational system of the country. It is an organ-
ization which proceeds on the wise premise
that, in the case of science, the best way to get
the fruit is to cultivate the tree. It is an or-
ganization which is proving successful and
economical. Its output has proved a more than
liberal return on the funds at its disposal.
But essential to its continuance is continu-
ance of adequate financial support from the
government.

RESEARCH INSTITUTES AND THEIR
VALUE!
In this restless, drifting world in which we
now live, even intelligent people are not always
appreciative of the fact that many if not most
of the great intellectual achievements in various
fields have been accomplished only when the
thinker has been protected from the interrup-
tion and annoyance of passing events and per-
mitted to work out his ideas somewhat apart
In the
Middle Ages, the alchemist, the philosopher or
the mathematician retired to a garret or cellar
and there achieved his purpose, and even to
this day the idea that starvation and a garret
are successful stimulants to scientifie investiga-
tion clings persistently to the popular mind,
together with so many of those superstitions by
which humanity is still largely guided. Truth
is that the thinking man in the middle ages
was driven into a garret and often compelled
to accept poverty because his thoughts or dis-
coveries had no commercial value or popular
interest, and, if published, sometimes led to
controversies settled once for all by that unan-
swerable argument of authority, the fagot and
the stake. The example of Servetus must
surely have been a severe blow to hasty pub-
lication. One of the early masters of medi-
cine, he died a martyr to his printed opinions
at the early age of 42, his old friend, John
Calvin, seeing to it, it is said, that the fire was
well started.
But the time when important extensions of
the boundaries of knowledge, especially in sci-
ence, can be accomplished in garret or cellar
with no material except brains, a little sealing
wax, some wire and a few pieces of glass,

ton Memorial Hospital, Harvard University, May

which was about the equipment with which
Faraday made some of his most valuable dis-
coveries in electricity, has long since passed.
Brains are still the chief essential, but modern
science has gone in most of its phases beyond
the stage of easy discovery of important prin-
ciples. No clearer demonstration of the fallacy
of the popular belief in the capacity of the
man in the street to solve complex problems
exists than the report of the Naval Consulta-
tion Board in which it is shown that of one
hundred and ten thousand suggestions received
only one in a thousand were even worth con-
sidering, and of this one hundred and ten only
one was put into production. A few highly
trained scientific men, on the other hand, made
most of the useful discoveries. To-day scien-
tific advance in most fields depends upon the
use of equipment of great delicacy and pre-
cision, and unfortunately only too often of
very high cost. The time calls, therefore, for
the organization and classification of research
problems and a higher degree of collaboration
between scientists than has ever been had be-
fore, and it is characteristic of that vision
which has so often been a quality of Harvard
thought and action that we are gathered to-
gether to celebrate the opening of a laboratory
devoted to investigation in a field of science
but newly set aside, that of biophysics. The
name is new, though the science itself is not.
When the professor of anatomy in the Univer-
sity of Bologna first used frogs’ legs as a gal-
vanometer to reveal the presence of electric
currents, he was studying biophysics, even if
in a somewhat elementary form. In our own
times this new field for research has been
sequestered from the disciplines of biology and
physies as a special region, possibly because
the knowledge of the chemistry and the physics
of the human body has reached a point in its
advance at which there is a httle slowing-up
in the rate of important discovery. In such a
dilemma a shrewd scientist does not keep up a
frontal attack, but quickly shifts to a shghtly
different approach to the problem. Thus, by
the combination of the technical methods of
physies and of chemistry in the study of living
matter there is promise of an ample yield of
valuable knowledge within the next few years
and of a material advance which may possibly
SCIENCE
[Vou. LV, No. 1434
again illuminate the purely physical and chem-
ical methods of attack on the secrets of life
and in consequence lead to still further achieve-
ments in those fundamental sciences. Illustra-
tions of the fertilizing value of this method of
shifting the line of approach can be culled
from the lives of many successful investigators.
Pasteur is said to have started early in his life
on the study of tuberculosis, but to have
dropped it quickly when he found that he could
make no headway with the technique then in
use. If he had persisted, his name would not
be known to-day. Paul Ehrlich spent several
years investigating the problem of cancer, but
as soon as he found that progress was slow
and far-reaching results were doubtful, he
quickly shifted to the more profitable field of
an attack on parasitic diseases by means of
chemical compounds, and there achieved a great
and deserved success.
As it is one of the marks of genius to over-
come obstacles with the least possible waste of
energy, so the fact that this special field of
biophysies has been selected for a concentrated
attack affords an admirable criterion for the
intelligence of those controlling the funds for
cancer research in Boston. The world will
profit by the investigations which in the future
will be made in this laboratory, for in contrast
to the worker of the older days, who so often
concealed the results of his studies in order
that he might reap some benefit from them, the
modern scientist gives freely and at once to
the public everything he achieves. He does not
conceal or patent a valuable discovery which
would in any way relieve human suffering.
The true investigator’s chief stimulus is the
love for his science and ambition for his insti-
tute; and the responsibility imposed by the
great opportunities at his disposal will be, if
he is the right sort, one of the strongest forces
in sustaining the arduous labor of research.
This concentration of responsibility and the
development of intellectual power and leader-
ship as problem after problem is solved is an
important factor in the success of a truly scien-
tific institute, a factor the psychology of which
has often been overlooked by those administra-
tors who wish to impose the regulations of the
machine shop in order to obtain quantity pro-
duction in science.
JUNE 23, 1922]
Besides the direct way in which an institu-
tion like this, devoted to research in some phase
of pure or applied science, benefits humanity,
there is also an indirect influence, not so fully
appreciated. This is the reflex effect upon the
university as a whole, for only by the posses-
sion of sueh centers of intellectual concentra-
tion does the university become a university in
fact rather than in name. Every great teach-
- ing institution should be surrounded by a con-
stellation of independent institutes such as this,
devoted to the amassing of pure knowledge,
without a view necessarily to its future use or
practicality and without the encumbrances to
effective thought which go with administrative
work of the teaching of large numbers of im-
mature students. Our men of genius in the
universities still do too much undergraduate
instruction and teach the teachers too little.
This is one of the great defects of the present
scheme of education, in that it accentuates
routine and overlooks the spirit. When a uni-
versity possesses a genius he should be tenderly
protected and cherished. The ragweed will
outgrow the orchid, as has been proved a thou-
sand times. Why saerifice another orchid to
the test? But in research institutions lies true
freedom of thought in the university. While
to the undergraduates we must temper some-
what the boldness of our theories, in the re-
search laboratory everything must be free. No
one can foresee in what direction investigation
must proceed. No hampering politicians, as in
some state institutions, should be allowed to
control the direction and type of investigation
to be done, their equipment for this function
as regards the natural sciences being usually
somewhat less than that possessed by our
Great Commoner, who is making so brave and
useless a fight against the dangerous theories
of evolution.
Who in his wildest moments could have
imagined that the classification and anatomical
study of the fleas which infest lower animals
could ever have been of use in the saving of
human lives? Yet when the Oriental plague
threatened this country, in the results of such
studies was found the means of combatting
the disease, the uncontrolled ravages of which
can best be learned by a reading of that old
SCIENCE.
659
classic of Daniel Defoe’s, “A Journal of the
Plague Year.” When we realize that because
of our knowledge of public health obtained by
research on apparently unimportant matters
the repetition of such a plague is now impossi-
ble, we must be grateful to some of those who
have made heavy sacrifices in the cause of
science.
A few institutions like this will answer most
effectively the statement recently made in the
daily press that the foot-ball coaches had done
more for Harvard than all the professors would
ever accomplish—and this of a university which
can claim Agassiz, Lowell, Norton, Child, Gibbs,
Shaler, Royce and William James as only a
few among those who have passed on. To
enumerate the names of the living who are still
doing for Harvard what these men did would
be an insult to the intelligence of my audience.
The new building which we are gathered to
inspect shows in its very architecture the
thoughtfulness of those who planned it—simple
as every workshop should be, for that is all a
laboratory is, a place for labor. It shows that
the money which has been given has gone on
the inside rather than on decoration. I look
forward to a day when architects will sacrifice
all their art for the practical in laboratory
building, and reserve the demonstration of
their skill for libraries, museums and other
structures which may properly give room for
the display of artistic qualities.
But the building is not important. An insti-
tution of this type is always, it has been well
said, the lengthened shadow of a great man.
Those who are to work in it are far more im-
portant than any physical structure. The name
in itself gives promise of long and useful
service, bearing as it will the title of a line of
famous surgeons. The annual reports of the
Harvard Cancer Commission show how much
has already been achieved. There are few
groups of investigators in any country who
have produced with relatively small means so
much of sane, cautious, solid research work
in cancer, biology and physies as have those
who in the past have worked in the Huntington,
and who are now. to enjoy greater facilities,
and so may properly be expected to do more
and more as the laboratory expands. For
660 *
expand it inevitably will. It is said that oppor-
tunity knocks but once at the door, but this is
the opportunity of receivers, not of givers.
To the latter there is no limit. If this building
had been built and equipped five years ago,
we might not have had to share with our great
scientific rival on the continent the discovery
of many capital facts concerning the X-ray,
for it was only the lack of equipment which
kept the brilliant group of physicists who,
under the leadership of Professor Duane, have
made so many important advances in the the-
oretical study of X-rays, from covering many
of the practical phases developed instead by
our continental colleagues. The verification of
the quantum relationship between the fre-
quency of the X-ray and the voltage applied
to the tube, as demonstrated by Duane, Hull
and Webster, is a shining achievement which
might easily satisfy any university for a long
period of time. The work of Tyzzer on animal
tumors especially laid the foundation for much
recent research, while the demonstration by
Bovie of the relationship between certain light
rays and the coagulation of protein and the
killing of cells is also a most important con-
tribution to the newer aspects of biophysics.
Whether the problem of cancer—that last great
and as yet unanswered question in medicine—
will be solved here, no one can say. But I am
sure that the attack will be a brave one and
that the results will be characterized by the
same scientific caution and freedom from at-
tempt at dramatic effect that have marked the
work of the Harvard Cancer Commission in
the past. We all look to this laboratory as the
souree of the highest type of scientific investi-
gation combined with an unusual amount of
common sense on the human side, due obviously
to the influence of the director, Dr. Greenough.
There is no reason to think that with the pass-
ing of time there will be any change in this
high standard. 8
Let us all hope then that this building and
its equipment and staff represent merely a
beginning from which research will go forward
on a broader and broader scale, until at some
future time we may have a better insight than
at present into what has hitherto successfully
evaded human inquiry—the nature of life and

tion of the cancer problem will be in sight.

' THE EFFECT OF THE NATURE OF
THE DIET ON THE DIGESTI-
BILITY OF BUTTER
Ir is estimated that in the United States
about 18 pounds of dairy butter are consumed
per capita yearly and of this amount the
larger portion is used for table purposes.
This indicates quite conclusively that in spite
of the inereasing variety of fats available for
table and culinary purposes, dairy butter still
remains one of the most popular and widely
used edible fats. Formerly it was very gen-
erally believed that the principal if not the
entire food value of butter was due to the
energy which it supplied to the diet. The
recent discovery that dairy butter contains a
relatively large amount of vitamin A, which
has been shown to be essential for an adequate
diet, has served to further increase the popu-
larity of this extensively used fat.
The very general use of butter for food pur-
poses is no doubt responsible for the early and
continued attention that has been given to a
study of its nutritive value by physiological
chemists and nutrition experts. Many diges-
tion experiments have been carried on both in
this country and in Europe to determine its
digestibility, but since the experimental pro-
cedures of the different investigators were not
uniform the results obtained do not permit of
direct comparison. The lack of uniformity in
experimental conditions is perhaps most notice-
able in the wide variation of the nature of the
basal ration used by the different investigators.
However, this variation in the nature of the
foods comprising the experimental diets per-
mits to some extent a comparison of the effect

stituent of nearly all diets the following résumé
of digestion experiments, conducted by the au-

of the nature of the diet on the digestibility of
butter. Rubner, in a lengthy series of experi-
ments, reports three different values for the
digestibility of butter—for a simple diet of
butter and potatoes! 96.3 per cent., for a diet
of green beans and butter? 91.5 per cent., and
for the latter diet with a larger portion of
butter? 97.3 per cent.
Malfatti studied a diet of polenta (a por-
ridge of Indian corn meal) and butier and
found that butter was 97.7 per cent. digested.*
Mayer determined the digestibility of butter?
eaten as a part of a simple diet and reports
98 per cent. and 97 per cent. respectively as an
average of three periods of three days each
with a mature subject and a nine year old boy.
Atwater conducted digestion experiments on a
diet of fish and butter and found the butter®
to be 91 per cent. digested. Huldgren and
Landergren, who served as their own subjects,
found the digestibility of butter,’ eaten in con-
junetion with hard rye bread, was 95.4 per
cent. Luhrig studied the digestibility of butter’
served with a basal ration of meal, bread and
vegetables and reports a digestibility of 96
per cent. for butter. Von Gerlach determined
the digestibility of butter? when it was eaten
with a basal ration of rice, zweiback and oat-
meal and found it to be 97 per cent. digested.
Since in the metabolism experiments noted
above that are not uniform there are many
factors, such as food, habits, oceupations, and
races of people employed as subjects, it is un-
wise to attempt to generalize to any extent on
the effect of the nature of the diet on the
digestibility of butter.

wide spread use of dairy butter in conjunce-

tion with many kinds of food materials, it
appears of interest to summarize briefly a
number of digestion experiments in which
butter has been included as a part of the
experimental ration and which have been con-
ducted under identical experimental conditions,
as regards the type of subjects, the length of
experimental period, and methods of chemical
analysis. In many of the digestion experi-
ments conducted by the writer to determine the
digestibility of cereals, legumes, meats, vegeta-
bles and flours, butter has been employed as a
source of fat for the experimental diet. The
butter included in the experimental rations was
uniform in that it was always obtained from
the same source. Since the digestion experi-
ments considered here were made during a
period of four or five years, no attempt was
made to use a single lot of butter for the entire
series of experiments, but it is believed that
this butter obtained from a single creamery and
presumably from a constant source of milk
supply was typical of the ordinary commercial
butter purchased by the average consumer.
The table on p. 662 contains the data essen-
tial for the consideration of these experiments
and the text which follows includes a discussion
of the details of the different types of diets.
The first group of experiments referred to in
the table, eight in which dairy butter was
the food material studied, are discussed in
detail in the initial paper? of a series which
has appeared from time to time reporting the
results of digestion experiments conducted to
determine the digestibility of a large number
of edible fats and oils. To secure data con-
cerning the relative digestibility of edible fats
and oils several digestion experiments with
each of the fats studied were conducted under
uniform conditions. The experimental ration
consisted of commercial wheat biscuit, fruit,
sugar, tea or coffee and a special cornstarch
pudding or blanemange in which was incor-
porated the fat under consideration. In order
to mask any noticeable flavor or odor of the
fats studied, the blanemange was heavily fla-
vored with caramel which gave a uniform char-
acteristic caramel flavor and odor to all the

experimental diets which included edible fats
and oils. Hight tests were made with this type
of diet to determine the digestibility of butter
and it was found that on an average butter
was 97 per cent. absorbed by the body.
The studies of the food value and eulinary
possibilities of the dasheen, a variety of the
taro (Colocasia esculenta), which is a staple
constituent of the diet in large areas of the
tropical countries, included a number of diges-
tion experiments.11 Since the advisability
of the introduction of the dasheen into the sub-
tropical regions of the country where the white
potato can not be successfully grown or stored
was under consideration, it was of considerable
importance to have data concerning its digesti-
bility. The basal diet for the digestion experi-
ments with dasheen consisted of milk, which
supplied the larger portion of the protein of
the diet, fruit, and butter, which, with the fat
from the milk, supplied the fat of the diet.
The carbohydrate portion of the diet was
largely derived from the dasheen. The results
of these experiments show butter to be 96 per
cent. digested when eaten as a part of a diet
in which the carbohydrates were largely starch,
derived from a starchy vegetable.
During the World War when it became neces-
sary to conserve all resources to the utmost, the
writer became intensely interested in promoting
the use of the soy-bean and peanut press-
cakes for human food. The expression of oil,
under sanitary conditions, by the “cold

Dept. Agri. Bul., 612 (1917), pp. 11.
process” from sound, clean soy-beans or pea-
nuts produces a virgin oil and a high grade
press-cake rich in protein. These legume pro-
teins glycinin (soy-bean) and arachin (peanut)
yield on hydrolysis a large amount of lysine,
the amino acid essential for growth. The re-
ported results of the chemical and biological
examination of soy-bean and peanut proteins
demonstrate beyond a doubt their high nutri-
tional value. In order to supplement this data
with information concerning the digestibility
of these proteins, digestion experiments!” were
conducted in which the soy-bean and peanut
press-cake flour combined with wheat flours
was served in the form of biscuits. The
experimental diet consisted of biscuits, fruit,
butter, sugar and tea or coffee. Butter was
served as a spread for the biseuits and lard
was used as “shortening” in their preparation,
accordingly the values reported for digesti-
bility apply to the total fat of the diet rather
than to either individual fat, but as both
butter?’ and lard?® have been reported as being
97 per cent. digested, it is of interest to note
the effect of the soy-bean and peanut flour
diets on their digestibility. Since butter con-
_stituted a half or more of the total fat of the
experimental diets and since the reported
digestibility for the total fat of the diets was
for the soy-bean experiments 94 per cent., and

Dept. Agri. Bul., 310 (1915), pp. 22.
JUNE 23, 1922]
for the peanut experiments 97 per cent., it is
evident that the digestibility of butter was low-
ered little if any by the other constituents of
this type of diet.
From the results of the many attempts that
have been made to find cereals suited for eulti-
vation in the semiarid regions of this country
it appears that the so-called non-saccharine
grain sorghums are best adapted for the pur-
pose. While these cereals are extensively
included in the dietary of India, China,
Abyssinia and South Africa, there is little re-
corded data relative to their digestibility. Ac-
cordingly digestion experiments were made to
secure information concerning their value for
human nutrition. Of the many non-saccharine
grain sorghums which may be grown in the
semiarid regions four, Dwarf Kafir, Feterita,
Milo and Kaoliang, were chosen as typical.
To determine the effect of cooking, ete., upon
digestibility, experiments with the non-saccha-
rine sorghums prepared in a variety of forms
have been made by the writer but for the dis-
cussion here only those in which the sorghums
were cooked and served as a mush will be con-
sidered since in these diets butter constituted
practically the entire fat content of the diet.
In this type of digestion experiments!* with
the grain sorghums the diet consisted of the
cereal cooked as mush, apple sauce, butter,
sirup, sugar and tea or coffee if desired. As
may be noted from the above table the results
of the digestion experiments with the non-
saccharine sorghums show that their proteins
are very incompletely absorbed by the body,
due probably to the proteins being inclosed
in the very tough cellular structure of the
cereal. This coarse, rough, cellulose also may
increase peristalsis to such an extent that the
diet passes more rapidly than normal through
the alimentary tract. If this theory is tenable
it may also explain the lowered digestibility of
butter, which was for the kafir experiments 92
per cent., for those with feterita 92 per cent.,
for those with milo 92 per cent., and for those
with kaoliang 90 per cent.
For a long time considerable attention has

Sorghums,’’ U. 8S. Dept. Agri. Bul., 470 (1916),
pp. 30.
SCIENCE
663
been given to the desirability of including or
excluding wheat bran in milling wheat flours.
Inasmuch as the annual per capita consump-
tion of wheat?® is approximately five bushels
this question assumes considerable importance,
and among the factors to be considered in ar-
riving at an intelligent solution of the problem
is the extent to which the bran is digested by
the human body. To obtain data in this con-
nection a number of digestion experiments
were made with coarse unground wheat bran
and bran which had been ground to resemble
flour in fineness. In these experiments!® the
bran was incorporated in a_ gingerbread
and served in conjunction with potato, fruit,
butter, sugar, and tea or coffee. As in
the soy-bean and peanut flour experiments, lard
was used as “shortening” in preparing the
gingerbread and butter was served as a spread
for the bread. Hence the values reported for
the digestibility of fat refer to total fat of the
diet. However, since a large portion of the
total fat consumed was butter and since in the
fine wheat bran experiments the total fat was
95 per cent. digested and in the unground bran
experiments it was 94 per cent. digested, it is
evident that for practical dietetics this type of
diet did not lower the digestibility of butter.
According to reports’ the large packing
houses use the “hard palates” of cattle, which
are taken from the roof of the mouth of beef
animals, in the manufacture of potted meats
and sausage in amounts varying from 2,500
Ibs. to 6,000 lbs. monthly. Since chemical
analysis showed that hard palates contain ap-
proximately 20 per cent. of protein it was de-
cided to determine to what extent this protein
was digested by the human body and seven
digestion experiments'’ were made in which
the ration consisted of potato, crackers, butter,

sugar, tea or coffee and the hard palates served
in the form of meat loaf. Butter was used in
the preparation of the meat loaf and it was
also served as a spread for the potatoes and
crackers. From the results of the digestion
experiments with the hard palate it was found
that the total fat of the diet was 94.6 per cent.
digested. Since the greater portion of the fat
consumed was butter this figure is virtually
that for the butter included in a protein rich
diet—an average of 131 grams of protein
was ingested daily by men employed at seden-
tary occupations. This should be sufficient
indication that butter is very completely ab-
sorbed when eaten in conjunction with a high
protein diet of this character.
SUMMARY
From the foregoing results of numerous
digestion experiments it is evident that dairy
butter is very completely utilized by the human
body. In those diets in which the accessory
foods were very nearly if not entirely absorbed
by the human body, butter was found to be
practically completed digested. When coarser
materials, particularly those which provided
considerable refuse, were included in the diet
it was found that butter was somewhat less
completely absorbed by the body. The general
conclusion to be drawn from the results of the
digestion experiments cited above is that butter
eaten in conjunction with ordinary food mate-
rials is very completely digested and that for
the diets studied, the nature of the diet does
not produce a marked difference in the amount
of butter absorbed by the human body.

ARE SCIENTISTS ENCOURAGING
POPULAR IGNORANCE?
I HEARTILY agree with the view of Mr.
Halsey that readers of Science should become
familiar with the anti-metrie case as presented
in the recent report of the National Industrial
Conference Board, The Century Company,
$2.00. This report gives the pro-metric argu-
ment as well as the anti-metric argument and

is, therefore, signed by the metrie members of
the committee, but not as Mr. Halsey states,
“because they could not do otherwise.” Scien-
tists do not need to be told the pro-metric
argument, but they should know the character
of the arguments advanced by the so-called
American Institute of Weights and Measures
against the metrie system, Mr. Halsey being
their paid commissioner. Beyond quoting
them at length no comment of mine is neces-
sary.
For years.... the minds of children have
been trained to believe in it (the metric system)
as the only scientific system certain to become
universal. Children leave school imbued with the
metric fallacy. . . . Editors of newspapers know-
ing practically nothing about the subject have
aped the schools and colleges, taught the fallacy
and increased the ignorance. In the encourage-
ment of the popular ignorance lies the chief
danger to our established standards. p. 193.
Advocates of the English system deny most
emphatically that there is amy demand worth
serious consideration in favor of a change to the
metric system in the United States. The deduc-
tions drawn from lists of names presented by the
metric advocates ... are wholly fallacious and
misleading. . . . If this is the best the pro-metrics
ean show, only 60,000 to 80,000 people in the
United States out of a population of one hundred
millions—less than one tenth of one per cent. of
the whole—favor a change. Such a demand...
could be accounted for by the scientific group in
this country, which comprises about this propor-
tion of the population and is known to advocate
the metric system. . . . The propaganda in favor
of the metric system has emanated from one or
two propaganda organizations working for the
purpose, which have spread broadeast throughout
the United States literature of an essentially
misleading character. ... The prominent indi-
viduals most frequently quoted as favoring the
metric cause are not industrialists and business
men, but such professional men as teachers, doc-
tors, inventors and others who are interested
chiefly in the scientifie aspects of the question and
have nothing of material value at stake or have
espoused the cause as fallaciously represented by
metric propagandists without having given due
consideration to the practical side of the issue.
p. 192.
We note that the American Association for
the Advancement of Science, the American
JUNE 23, 1922]
Chemical Society, ete., have repeatedly passed
strong resolutions in favor of the metric system
and if we have been duped it is time to know it,
because scientific men and teachers do have
something at stake in the prosperity of
America. We should be informed as to who
these propagandists are who are spreading
ignorance, what their motive is, and convincing
evidence should be given and not merely dog-
matic affirmations.
Practically all the real sentiment in favor of
a change... comes from teachers, scientists,
some engineers and from a few manufacturers
making refined instruments or other articles re-
quiring a minuteness of measurement. p. 194.
Science stands in a unique position. Its methods
are ever changing and are easily changed. . . The
number of persons and interests involved in the
field of scientific activity are small compared with
those involved in other fields. For these rea-
. .. the usefulness of parts of the metric
system in scientific work and in fine instrument
making can not be taken as an indication of the
advisability of adopting it gradually in the United
States. p. 145. In fact, it is the so-called ‘abso-
lute’ or centimeter-gram-second (C. G. 8S.) system
rather than the metric system which is actually
employed in scientific work. p. 145. In engi-
neering practice it is, as in scientifie work, a mix-
ture of other units that is used and has been
found of advantage in some connections rather
than the metrie system exclusively. This is dem-
onstrated in electrical engineering ... where a
‘mongrel system’ comprising the C. G. S. or abso-
lute system, the metric system with the centimeter
instead of the millimeter as a unit, and English
feet, inches and square inches, is used. The units
of electrical measurement, the ohm, ampere, volt
and others ... are not intrinsically more metric
than English. p. 147.
Whether the absolute system bears the stigma
of a “mongrel” system because of the use of
the centimeter instead of the millimeter or
because of the character of the gravitation con-
stant or because there are 60 seconds in the
minute is not clear, but it is hardly an argu-
ment against the adoption of the metric system
in any ease.
English measures and weights are no _hap-
hazard modern invention, but have come down to
us from prehistoric times. p. 4.
This will be news to many who have been led

to suppose? that the English yard has been
recently established on the basis of the standard
meter, replicas of which are kept by the U. S.
Bureau of Standards. But the report says:
In fact, the Anglo-Saxon measures of length
down to the present have remained on the same
basis as is given in the statute of Edward II
(1824) where a statement in statutory form of
what has since become the well-known rule that
‘three barley corns round and dry make an inch,
Eten) “pslo:
“‘The .organic growth and selection of the
fittest units in the English system make it infinite-
ly better adapted to different uses than the metric
system. p. 138. In short, from every angle,
the metrie system is devoid of the English sys-
tem’s handiness and convenience; its units are
either too large or too small for general every-
day requirements. ... The character and names
of its units are so tied in with every-day experi-
ence that they are readily learned and retained;
and the features just mentioned make the English
system, as compared with the rigid and inflexible
metric system, much more comprehendible to the
average mind, and more convenient, adaptable,
and comprehensive in filling the needs a system of
weights and measures is called upon to fill. p. 140.
The current extensive use of decimals in con-
nection with English units in modern ealeulations
has made the work of computations in that system
as easy as in the metric system. The rapid devel-
opment and extensive use ot calculating machines,
slide-rules, ete., has . . . enabled computations of
whatever kind to be made with equal ease in any
system, so that the metric and English systems
have in present practice been put on the same
footing in this regard. ... Supporters of the
English system deny that there would be any
saving of time through the more general use of
the metric system in the schools. p. 143.

The United States yard and the British imperial
yard were found to differ in length by one ten-
thousandth of an inch, but the imperial yard
differs in length from its authentic copies by
amounts which are at least as great as this. Con-
sequently, it was hopeless to obtain the exact
length of the yard and on April 5, 1893, the meter
was taken as the standard unit of length for the
English system in the United States and contain-
ing exactly 39.37 inches.
666
The same argument in England is made in re- -
gard to Wnglish money.
The English system... has been found ac-
ceptable to the great majority of the Latin-
American importers and the imports into these
countries consist in preponderant degree of manu-
factured products into which the English system
of weights and measures is definitely incor-
porated,’’ in spite of those countries being metric.
p- 158. ‘‘Of the millions of dollars worth of ma-
chine tools which . . . have (been) sold to France
and Germany, the great majority have been sold
without request or suggestion that any of the
dimensions be made in accordance with the metrie
system. p. 159.
It would be impossible gradually to substi-
tute new metric standards and equipment for the
old as the latter wore out without catastrophic
confusion to industrial processes through a pro-
tracted period. Even if the change were made
suddenly, ...a long transition period fraught
with confusion and disorder would inevitably
follow. p. 175.
The proposal actually made by scientists that
as far as possible metric designations be used
for our existing English standards the report
dismisses briefly by saying that it
is impractical and in any event would be quite
pointless because it could hardly be considered an
adoption of the metric system. p. 175.
Of the well-known case of the Baldwin Loco-
motive Works building locomotives for Russia
purely on metric specifications without chang-
ing their equipment, or working force or suf-
fering any inconvenience or delay, the report
says:
If we continue to make equipment to existing
standards and merely apply metrie designations
as was done in the case of the ‘metric’ locomo-
tives built by the Baldwin Locomotive Works,
this would be neither the adoption nor the use
of the metric system. It would merely be ex-
pressing in terms of the metric system, with which
the English is incommensurable, an existing stand-
ard dimension which is integral and exact in the
English system. Such a change, it is held, besides
being quite meaningless, would, if feasible, simply
introduce confusion and error through calling
things by wrong names. p. 176.
So the report proceeds to tell all of the dire
calamities that will certainly befall us when
the befuddled teachers and scientists have their
way over the practical every-day business man.
SCIENCE
[Vou. LV, No. 1434
No possible advantages could result from a
change to the metrie system, but on the contrary,
through such a change Great Britain and the
United States would lose the vast trade they now
possess with non-metric countries and with respect
to metric trade they would surrender their ad-
vantages to such metric countries as France and
Germany. p. 160.
In spite of Mr. Halsey’s statement given
above that products incorporating the English
system can be used in countries which have
adopted the metric system, it appears that if
we adopted the metric system we could not do
the same.
Some conceptions of the difficulties which would
be involved in such a destruction of standards is
given in the following: ... All rules, tables,
formule, used in calculations involving measures
of length. All drawings of manufactured articles.
All measuring scales and measuring tools, calipers,
verniers, ete.... All machine tools, leading
screws of lathes, . . . locomotives, cars, railroads,
and their appurtenances, all marine and station-
ary engines, all ships. p. 177. We can not regard
the use of both systems on the same machine as
a thing to be tolerated, much less deliberately en-
couraged. p. 179.
The man who can estimate or indicate in
words the value of mechanical standards to this
country does not live. The cost of attempting to
change air-brake hose couplings is not represented
by the value of the tools for making the couplings
in the Westinghouse Works, but by the infinite
confusion of the railroads in getting from one
standard to another. p. 187.
Finally the report attempts to show that
whereas every civilized country except Great
Britain and the United States is metric, this is
only nominally the ease.
The statement that the countries named
(France, Germany, Norway, Sweden, Belgium,
Switzerland, Italy, Japan, the Central and South
American countries, ete., and the Latin acquisi-
tions of the United States) customarily employ
the metric system is a pure assumption. No eyvi-
dence of this is submitted, while, on the contrary,
all available evidence shows that in some of these
countries the system is used but little, and in
none of them is it universal. p. 168.
Hence the report suggests
that a conference of Great Britain, the United
States and other countries be called to study care-
fully all natural systems of weights and measures
JUNE 23, 1922]
with a view to a more complete standardization
of the inch and the foot the world over and to
draft legislation ... legalizing it in various
countries as a world standard along with, if not
superseding the metric system. p. 211.
The reader is referred to the report to see that
the true spirit of the argument of the report
has been preserved and also to get tke pro-
metric side.
Such a tissue of deliberate misrepresentation
needs merely to be presented to scientific men
for its refutation line upon line. Were it true
that American scientists and teachers are
spreading ignorance, this report would deserve
to be a “best seller.” But the challenge which
it contains should not go unmet. The Council
of the American Chemical Society at its recent
meeting voted to ask the various scientific, edu-
cational, engineering, medical and pharma-
ceutical societies to send representatives to the
Pittsburgh meeting of the society in September
to consider what further steps can be taken
toward the gradual introduction of the metric
system. Here is an opportunity to answer the
challenge.
The best answer to Mr. Halsey’s contention
that it can not be done is that 7t 7s being done.
There has just come to hand the current schedule
of chemicals of the national government, which
is class 4, which has practically all pure chem-
icals listed in metric units only. Henceforth
all pure chemicals appearing on the general
schedule of supplies will be listed and pur-
chased entirely in the metrie system for the six-
teen bureaus of the government.
In a volume which has just come from the
press entitled Metric System for Engineers,
written by Charles B. Clapham, a London engi-
neer, the author gives an unbiased answer to
many of the anti-metrie arguments. For ex-
ample, he says:
All the metric serews likely to be required
can. be cut on the usual English and American
lathes, well within the accuracy required for manu-
facturing purposes, if one additional change wheel
is provided. p. 33.
He says significantly, p. 148:
In considering the cost and inconvenience
aspect, it is to be feared that many false objec-
tions have been put forward; ete.

He notes that a hundredweight contains 112
pounds, that a “stone” if used in weighing
potatoes consists of 14 pounds, but when
weighing butcher’s meat contains~ only 8
pounds! This is far surpassed, however, by
the complexity of the United States bushel.
The use of the metric system is steadily grow-
ing, every school-boy talking of wave-lengths
in hundreds of meters. Much further informa-
tion on metrie progress is given in an excellent
work on World Metric Standardization pub-
lished by the World Metric Standardization
Council of San Francisco.
The Valve World for May, 1922, states:
More than 215 member organizations of the
Chamber of Commerce of the United States have
gone on record in favor of gradual metric stand-
ardization. More than 15,000 manufacturers and
engineers have petitioned Congress to enact
metric standards legislation, and these represent
concerns capitalized at several billions of dollars.
The states of Maine, Connecticut, New Hampshire,
Utah, Illinois, California, North Dakota and
Tennessee have officially memorialized Congress
to adopt the metric system as the sole system of
weighing and measuring for the benefit of all the
people of the United States.
One is reminded of an old couple up in Ver-
mont who went to town; and, passing a shop
window, Lucy remarked, “George, why don’t
you buy a new hat in place of that disgraceful
old thing?” To which George replied without
going inside to inquire the price of the hat he
saw, “I can’t afford it. Id have to get used
to a new one. Besides I like the old one and I
couldn’t wear two.”

AMERICAN COMMITTEE TO AID
RUSSIAN SCIENTISTS WITH
SCIENTIFIC LITERATURE
Russian scientists have been almost com-
pletely cut off from access to western Huropean
and American literature since 1914. This iso-
lation, coupled with great physical hardships,
is naturally interfering with the progress of
their work, although it has by no means en-
tirely put a stop to it.
Through many sources appeals are coming
from Russian botanists, zoologists, chemists,
668
physicists, geologists, engineers and others for
the recent literature in their respective fields.
The craving of these men for contact with the
rest of the scientific world is very great. At
various times scientific groups in this country
have suggested the desirability of sending lit-
erature from this country to Russian scientists.
These suggestions have now resulted in the
formation of an American Committee to Aid
Russian Scientists with scientific literature.
The committee has arranged with the American
Relief Administration, of which Mr. Herbert
Hoover is chairman, to receive the literature
collected by the committee and assume the
entire care and cost of its overseas transporta-
tion and delivery to the distributing agency in
Moscow.
The literature will be distributed in Russia
among the universities, scientific societies and
individual scientific investigators by a special
committee representing the Academy of Sci-
ences and other recognized Russian scientific
organizations in cooperation with the American
Relief Administration which has representa-
tives in Moscow, Petrograd, Kiev, Kharkov,
Kazan and other university and academie
centers.
The American Committee to Aid Russian
Scientists is a voluntary and temporary organ-
ization of scientific men. Its activities will
continue only until the regular channels for
the shipment of scientific literature to Russia
are reopened. It has no funds for the pur-
chase of scientific books or scientific periodicals.
It must appeal, therefore, to the generosity of
the scientific societies of America, government
and state scientific bureaus, individual scien-
tists and publishers of scientific books.
The committee desires chiefly to obtain scien-
tifie books, scientifie periodicals, authors’ re-
prints, publications of government and state
scientific bureaus, scientific institutions and uni-
versity presses which are of an original scien-
tific character or contain technical information,
and which have appeared since 1914.
There is in Russia a fairly large number of
scientific institutions. It is out of the question
at the present time to undertake to supply ade-
quately all those institutions with literature,
but the committee hopes to provide at least
s1x copies of each publication, since it feels that
SCIENCE
[Vou. LV, No. 1434
this number may meet at least the more urgent
needs of the Russian centers of scientific en-
deavor at Moscow, Petrograd, Kazan, Kiev,
Odessa and a few other principal university
cities. If more than six copies can be spared,
so much the better. On the other hand, if this
number should be burdensome, a smaller num-
ber of ‘copies will be of service.
The committee has at its disposal only a
limited fund to cover the necessary clerical
work. It will, therefore, appreciate it if the
contributors of literature will cover the cost of
its transportation to New York, from which
point all cost of handling and shipment will
be borne by the American Relief Administra-
tion.
The committee hopes that the response to this
request will be whole-hearted and universal.
The assistance that American scientists can give
to the Russian scientists who are in distress,
besides being a good Samaritan act, will be a
real contribution to the progress of science. It
may also be the means of re-establishing the
normal exchange of scientific results between
the Russian and American scientists, and will
be a fine manifestation of the cooperation of
men in science throughout the world.
Contributors should send, in triplicate, with
each consignment a list of the publications for-
warded by them. These lists, together with all
letters containing advices of shipments, express
and shipping receipts, should be addressed to
the American Relief Administration, Russian
Scientific Aid, 42 Broadway, New York, N. Y.
The publications themselves should be sent
by express, or, if very heavy, by freight, to
the American Relief Administration, care of
Gertzen Company, 138 Jane Street, New
York, N. Y.
Requests for further information should be
sent to the American Committee to Aid Russian
Scientists, 1701 Massachusetts Avenue, Wash-
ington, D. C.

SCIENTIFIC EVENTS
THE AGITATION AGAINST THE TEACHING
OF EVOLUTION
Proressor J. V. DeNNEy, president of the
American Association of University Professors,
addressed on June 14 the following letter to
the moderator of the conference of the North-
ern Baptist churches meeting in Indianapolis:
As president of the American Association of
University Professors, I desire to call attention to
the peril confronting our higher institutions of
learning at the present time because of the ‘‘ Fun-
damentalist’’ or ‘‘anti-evolution’’ movement
which has appeared in two state legislatures and
in the constituencies of several colleges controlled
by or affiliated with the religious denominations.
Letters from presidents and professors indicate
widespread anxiety lest the cause of higher edu-
cation suffer serious injury through attempts at
coercive measures, interfering with the professor’s
duty to teach the truth of his subject as deter-
mined by the body of past and present laborers in
his own field and as confirmed by his own con-
scientious studies and researches. The chief
injury is not merely to the professor who loses
his position or to the particular institution that
sacrifices a permanent aim to a passing fear. It
is in the degradation of the office of teacher; in
the establishment of distrust and suspicion in the
publie mind towards all colleges and universities ;
and in the immediate loss to both church and
state of strong forees for good through the slack-
ening of devotion and enthusiasm and the encour-
agement of casuistry, subtlety and insincerity
among those who are ealled to teach with an eye
single to truth.
The colleges controlled by or affiliated with
religious bodies are public institutions in the
sense that they solicit and receive students on
terms common to all good colleges. They impose
on applicants no political or religious tests. They
forewarn the public of no doctrine in history,
economics, literature and the sciences that is
essentially at variance with the body of free and
aecepted teaching in these departments of learn-
ing throughout the country. Their professors co-
operate in the work of all of the learned societies,
and are bound by the code of honor in scientific
research and by the obligation of scrupulous hon-
esty of statement in teaching. Any invasion of
this high obligation is an attack on manhood in
teaching and destructive to real education.
Any college or university, whatever its founda-
SCIENCE
669
tion, that openly or secretly imposes unusual re-
strictions upon the dissemination of verified
knowledge in any subject that it professes to
teach at all, or that discourages free discussion
and the research for the truth among its pro-
fessors and students will find itself shunned by
professors who are competent and by students
who are serious. It will lose the best of its own
rightful constituency and will cease to fulfill its
high ministry. The same results, disastrous to
true edueation, will follow whether the restric-
tions are adopted voluntarily by the college itself,
or are forced upon its administrative officers by
the state legislature, an ecclesiastical body or by
powerful influence operating through trustees.
The question of legality and of good motive is
also irrelevant so far as moral and educational
results are concerned.
The five thousand members of the American
Association of University Professors in active
service in some two hundred colleges and univer-
sities of the United States are of one mind on
the fundamental necessity of preserving the
integrity of the teaching profession. They realize
that their work is a sacred trust that can be ful-
filled only in freedom of conscience, loyalty to the
truth, and a profound sense of duty and of per-
sonal responsibility. They claim the support of
all good Americans whatever their creed in re-
sisting measures that will prove ruinous to our
institutions of higher learning.
THE PROPOSED BOMBAY SCHOOL OF
TROPICAL MEDICINE!
We learn from India that the government of
Bombay has declined to proceed with the
project for establishing a School of Tropical
Medicine at Bombay. The news is not a little
surprising, for the government of Bombay had
very definitely expressed its intention to estab-
lish the school, and Sir Dorab Tata had prom-
ised to contribute a lakh of rupees a year
towards the expenditure which was to be in-
curred. The Bombay School of Tropical Med-
icine was to have been opened on April 1 last,
and all arrangements were made for this pur-
pose. It was only at the last moment that the
Bombay government determined to eut out of
the budget the whole sum allotted to the school,
and issued orders that the scheme should not
be proceeded with. In consequence Sir Dorab

Tata has withdrawn his offer, which was con-
tingent on the government founding a school
of tropical medicine at Bombay. As will be
seen, matters had gone very far before the
government of Bombay repudiated the under-
taking it had given. They had gone even
further than we have so far indicated, for
rather more than a year ago the Royal Society
was asked to select professors for the chairs of
clinical medicine and therapy and of proto-
zoology in the school. The Royal Society, act-
ing through its Tropical Diseases Committee,
issued advertisements widely—in this country,
in the dominions and in America. From among
the applicants it selected two, one for each
chair. The protozoologist selected was an
American, but he, we understand, subsequently,
on private grounds, withdrew his acceptance.
The successful applicant for the other chair,
an Australian (Professor N. Hamilton Fair-
ley), resigned his appointment in Australia to
become Tata professor of clinical medicine in
the Bombay School. The government of Bom-
bay has now given him notice that it will dis-
pense with his services on Oetober 31. The
situation thus brought about is obviously most
unsatisfactory, and the matter can not be
allowed to rest where it is. When the Royal
Society acts for the Indian government and
invites applications for positions on definite
terms, the candidates selected assume that a
written contract is superfiuous. Clearly the
Royal Society has been placed in a very false
position. At the request of the government of
India it undertook to select suitable persons to
occupy the two chairs. With the authority of
the government of Bombay the Royal Society,
through its committee, issued advertisements
inviting candidates to come forward and stating
the terms and conditions of the appointment,
which was to be in each case for a term of five
years in the first instance, “but may be ex-
tended by the government.” It is now left in
the lurch by the government of Bombay, which
professes to find that it has miscalculated its
resources and is not in a financial position to
carry out its bargain. The Royal Society will,
we feel sure, have the support of public opin- )
ion in any action it may take, and the medicaY
profession in particular will be anxious to see

that justive is done to Professor Fairley, if not
by the government of Bombay, then by the
government of India, which can not absolve
itself from xesponsibility for the acts of the
provincial government. We understand that a
new central research institute for India may
shortly be established, probably at Delhi; this
may afford the government of India a way out
of the false position in which it has been placed
by the government of Bombay.
THE ROYAL ACADEMY OF BELGIUM1
THE Royal Academy of Belgium celebrated
the one hundred and fiftieth anniversary of its
foundation on May 23 and 24 in the presence
of a large number of its members and of dele-
gates from other academies and learned insti-
tutions. On the Wednesday afternoon, May
24, numerous congratulatory addresses were
presented at the Palais des Académies, and the
members and visitors were afterwards received
at the Hotel de Ville by the Mayor of Brussels,
M: Adolf Max, and his aldermen, MM. Steens,
Vande Meulebrouck and Coelst; a reception
was held at the Palais des Académies in the
evening, where an exhibition of medals and
portraits connected with the history of the
academy had been arranged. The anniversary
celebration itself was held in the large hall of
the academy on the afternoon of May 25 in the
presence of the king, the minister of arts and
science, M. Hubert, formerly rector of the
University of Liége, Cardinal Mercier, and the
English, French, Dutch, Spanish and Japanese
ambassadors. The president, M. Vauthier, in
an address of welcome, briefly sketched the
history of the academy and its influence on the
intellectual development of Belgium. The min-
ister of justice, M. Masson, tendered the con-
gratulations of the Belgian government, and
Monseigneur Baudrillart spoke in the name of
the Institut de France. Sir William B. Leish-
man, as vice-president of the Royal Society,
represented the British universities and learned
societies; he referred to the activities of Belgian
bacteriologists and paid a high tribute to the
work of M. Jules Bordet. MM. Lameere,

the classes of science, of letters, and moral and
political sciences and of fine arts, contributed
summaries of the activities of their several sec-
tions of the academy. Later the visitors were
received by the king and the queen at the
Palace of Laeken, and in the evening a banquet
was held at the Hotel Astoria.

DEAN OF THE SHEFFIELD SCIENTIFIC
SCHOOL
Tue Yale Corporation has elected as dean
of the Sheffield Scientific School in succession
to Director Russell H. Chittenden, Professor
Charles Hyde Warren, since 1900 a member of
the faculty of the Massachusetts Institute of
Technology, where he has been professor of
mineralogy since 1915.
The dean-elect of the Sheffield Scientific
School served as an assistant in chemistry and
mineralogy in that school from 1896 to 1900,
studying in the Graduate School during this
period and receiving the degree of doctor of
672
philosophy in 1899. In addition to his teach-
ing at the Massachusetts Institute of Tech-
nology he has been extensively occupied with
expert work for various mining and manufac-
turing chemical concerns. He also carried out
a large quantity of research work of a purely
selentifie character.
Professor Warren is a member of the Amer-
ican Academy of Arts and Sciences and of the
Geological Society of America. He is also a
member of the Yale Chapter of the honorary
society of Sigma Xi. His published works
inelude “A Manual of Determinative Miner-
alogy” (1910), and contributions to American
and German technical journals.
Dr. Russell H. Chittenden has been a mem-
ber of the Yale faculty since his graduation
from the Sheffield Scientifie School forty-seven
years ago. He has been head of the Sheffield
. Seientifie School since 1898, when he succeeded
Professor George Jarvis Brush, first director
of the school. Dr. Chittenden offered his resig-
nation to be effective a year ago, but conceded
to a wish that he spend another year in office
until a suitable successor might be found.

Botanical Garden, in order that the memory of
Othniel C. Marsh and of his generosity to the
university may be more effectively perpetuated.
Othniel C. Marsh was a graduate of Yale Col-
lege in the class of 1860 who became the first
professor of paleontology in the university.
Professor Marsh died in 1899, bequeathing to
the university his former residence, which has
since been used as the School of Forestry. The
Botanical Garden is connected with this school.

Nature notes that the first meeting of the
“Institut International de Chimie Solvay” was
held in Brussels on April 20-27, under the
presidency of Sir William Pope. It will be
remembered that before the war the late M.
Ernest Solvay set aside a capital sum to be ex-
pended in the course of thirty years by the
International Institute of Physies, and that
meetings under the auspices of this institute
have been held in Brussels both before and since
the war. More recently M. Solvay set aside a
further capital sum of one million franes, also
to be expended in thirty years, for the promo-
tion of the science of chemistry. The meetings
of the institute are attended by delegates from
different countries, the number being limited to
about thirty, so that the discussions may be as
free and as informal as possible. The recent
meeting was devoted to the consideration of a
number of those questions which affect the
foundations of modern chemistry, and its pro-
gram included the presentation of papers on
isotopes, by Soddy, by Aston, and by Perrin
and Urbain; on X-ray analysis and molecular
structure, by W. H. Bragg; on the electronic
theory of valency, by Mauguin; on optical
activity, by Pope and by Lowry; and on chem-
ical mobility, by Job.

DISCUSSION AND CORRESPOND-
ENCE
OBSERVATIONS OF FALLING METEORITES
To tHe Eprror or Science: The numerous
recently reported occurrences of falling mete-
orites are so contradictory and so at variance
with what reason would lead one to expeet as
to make one quite cynical concerning the value
of human testimony.
Few natural phenomena, it may be stated by
way of introduction, are more likely to unduly
excite the imagination than those attendant
upon a fall of meteorites. The suddenness, the
unexpected nature of the oceurrence, the light
and noise, and perhaps above all the sensation
of fear aroused when a solid body is suddenly
projected from seemingly empty space, all have
effect, and it is not surprising that accounts
are widely variable—dependent upon the flex-
ibility of the imagination, more perhaps than
upon powers of observation. Few persons,
however well trained, can look calmly and crit-
ically upon the phenomena. Fewer yet can, in
the brief space of time, estimate the height of
the body when first seen, or note such facts as
may be of service in calculating its direction
and rate of progress.
A peculiar feature of the case is the lack of
ability on the part of an observer to locate the
place of fail unless, indeed, he happens to actu-
ally see it strike the ground. This is due to
several causes, and, in part at least, to the low
angle at which the stones sometimes enter our
atmosphere, which permits a continuation of
flight for some distance, even miles, beyond
the point at which they seemingly must strike
the earth, and in part to the fact that one is
unable to correctly estimate the distance, which
may be much greater than supposed. No less
an experienced student and collector than the
late H. A. Ward once told the writer of his
676
experience in such matters. He was sitting in
front of a house oceupying a somewhat ele-
vated position with reference to the rest of
the town. Suddenly a meteorite appeared
descending from the sky, and fell, he was sure,
within a certain square on the lower level. He
at once proceeded to the spot, only to find that
he was mistaken but that it had fallen a “few
blocks away.” At this second point the same
experience was repeated, and the stone finally
located some twenty miles beyond the point
where he was “certain” he had seen it strike.
An equally good illustration was offered in
the flight of a meteorite over the city of Wash-
ington on Sunday, January 12, 1919. This
was first called to my attention by a man some
eighty miles south of Washington who saw it,
as he assured me, strike the ground within one
half a mile of where he was standing. Inas-
much as the meteorite had been observed pass-
ing over Washington in a northeasterly direc-
tion his statement was not accepted. Further
reports of the fall in the immediate vicinity of
the city and a few miles away were also re-
ceived. Taking the direction along which the
meteorite was traveling, I followed it up by
correspondence for a distance of over 300 miles
into northeast Pennsylvania where it became
lost. The last reports received indicate that it
was going in two directions at once (!) and it
is very probable that it actually fell somewhere
in that vicinity, nearly 400 miles from where
first seen to fall.
Experiences similar to the above are com-
mon. In many other instances stones which
were “seen to fall” have proved to be of strictly
terrestrial origin. There comes a sudden flash
and report, the observer goes quickly to the
spot and there finding an object which had not
previously attracted attention, assumes it to be
a meteorite and in perfectly good faith writes
some museum announcing his discovery and
willingness to dispose of the same. There is
probably not a museum of importance in the
world that dees not annually receive from one
to many announcements of this kind. The re-
ceipt even of glacial boulders which were
“varm when picked up” or “which set fire to
the grass at the point where they fell” is not
unusual.
SCIENCE
[Vou. LV, No. 1434
This leads to the second point to which
attention need be directed—that relating to the
reported temperature of the fallen body, which
is often to the effect that “it was too hot to
touch,” or has been the cause of fires. As in
a great majority of cases it is impossible to
investigate the actual temperature after the
first report has been made it may be well for
the moment to consider the probabilities.
While the original source from which mete-
orites are derived is problematical it yet
seems certain that they have been wandering
for an indefinite period in space and at a tem-
perature of “absolute zero.” At the time of
entering our atmosphere it is fair to assume
they are cold throughout to a degree of which
we can have no conception. During the few
seconds in which they are passing through our
atmosphere, they become intensely heated on
the immediate surface, but these portions are
immediately stripped off, and, as we have abso-
lute proof, the heat never extends to a distance
of more than two or three millimeters. Before
striking the ground the speed of the body is
so far checked that it ceases to glow and the
thin film of molten material quickly congeals.
Cooling of the surface, owing to the intense cold
of the interior, must follow rapidly and it is
questionable in the writer’s mind if a large ma-
jority of the reports of the heated condition of
the meteorite when found are not based upon
expectation rather than fact. He even goes so
far as to suggest that when it shall become real-
ized by the public at large that the chances are
in favor of a meteoric stone being cold rather
than hot when found, it will be so reported.

ORIGIN OF SOIL COLLOIDS
Dr. Wuitney! has advanced an interesting
theory as regards the origin of .soil colloids.
He says, in part:
My present view is that particles of matter
derived from silicate rocks and other soil-forming
minerals when they approach a diameter of .0001
mm. contain relatively so few molecules that the
1 Science, 54: 656, 1921.
JuNE 23, 1922]
bombardment of the water molecules in which the
particle is immersed shatters the particle beyond
the ability of the molecules in the solid to hold
together as a solid mass. The atoms of calcium,
magnesium, potassium and sodium in the molecule
of the silicate would go for the most part into
true solution, while the atoms of silicon, aluminum,
and iron would go chiefly into colloidal solution
forming the basis of the colloidal matter or the
ultra clay of the soil. It should be possible for
the mathematical physical chemist, from physical
constants now known, to determine empirically the
relative size of the particle of matter which could
withstand such bombardment without complete
disintegration. This is a problem which has not
yet been worked out.
This is one way of looking at their origin,
but the results of our experimental work on soil
colloids force us to adopt quite a different view.
One that is not based on bombardment of water
molecules, but one based largely on chemical
reactions.
Many soil particles are hydrated silicates
which contain varying amounts of aluminium,
iron, silcon, sodium, potassium, calcium, mag-
nesium and other elements in smaller quanti-
ties. Soil chemists claim that these particles
are surrounded with a water-film, and that this
film is held tenaciously. In the light of this
the salts in the outer layer of these soil parti-
cles are subjected to constant hydrolysis. The
hydrolytic products of the soluble compounds
of sodium, potassium, ete., are partly taken up
by this water film by way of solution, and part
of them are adsorbed by the hydrolytic insoluble
products of the iron and alumina salts which
form a gel casing for the soil particle, that is,
there is an equilibrium of the soluble salt be-
tween the water film and the insoluble gel which
now surrounds the soil particle.
When the soil becomes flooded as after a
rain, and the water moves down through the
soil, the soluble salt of the water film is partly
removed by diffusing into the moving water.
This destroys the salt equilibrium between the
water film and the incasing gel, and, hence,
some of the soluble adsorbed salt is released to
the water film. This continues until most of
the soluble material is leached from the outer
layer of the soil particle. This leaching may
be continued until the incasing hydrolytic gel
SCIENCE 677
products of alumina and silica, and ferric¢
oxide may pass into colloidal solution. Not
only will the freedom of electrolytes tend to
bring the ineasing gel into colloidal solution
but some of the soluble salts themselves or some
salts that are moving through the soil under
the proper hydrogen ion concentration will
very much hasten their pepitization.
The pepitization of the hydrolytic insoluble
compounds removes the encasing gel and the
soil particle is again exposed to hydrolytie
action, and in this way the weathering of the
silicate particles proceeds. The pepitized gel
or hydrosol moves through the soil, provided
the pepitization is great enough, until it en-
counters a coagulating electrolyte or different
hydrogen ion concentration, when it comes back
as the gel and may be deposited on a soil par-
ticle, or come down as a precipitate where it
remains as an adsorbent and reservoir for plant
food until the conditions are sufficiently
changed for it to pass back into the hydrosol ;
that is, the process is reversible
hydrogel = hydrosol
and whether it is a hydrosol or a hydrogel de-
pends on the soil environment.
Certain soil salts in our work have brought
about a very beautiful pepitization, while other
salts have brought about an equally definite
coagulation. Then there are salts that lie in
between these extremes. Again the same salts
and same concentration have brought about
both coagulation and pepitization by changing
the hydrogen ion concentration.

A CRAYFISH TRAP
In ponds and streams where crayfish are
abundant they can be readily taken by means
of a trap constructed as follows: A rectangular
box of any convenient size, sixteen by twenty-
four inches for instance, is built of one-fourth
inch mesh galvanized screen wire. Into one
end of this box a removable funnel of like
material is fitted. This funnel should project
about eight inches into the box and have a
flattened opening about four inches wide and
an inch and a half deep. In setting the trap
678
it should be placed in shallow water on a slop-
ing bank and partially embedded in the mud
or sand so that the bottom of the funnel is
even with the bottom of the pond. The rest
of the trap extends out toward the deeper
water. A dead fish wired securely to the bot-
tom of the trap makes an excellent bait.
Attracted by this bait, the crayfish crawl into
the trap and seem to be unable to find their
way back out. A single night-set with such a
trap will reward the trapper with at least a
water bucket full of crayfish for laboratory
use, or for the more immediate purpose of
supplying the camp with an exceedingly de-
lectable breakfast.

SPECIAL ARTICLES
NOTE ON THE RELATION BETWEEN THE
PHOTIC STIMULUS AND THE RATE OF
LOCOMOTION IN DROSOPHILA
Ir is a fact demonstrated by many investi-
gators that Drosophila melanogaster (ampelo-
phila) is negatively geotropic and positively
phototropic. In addition it is also known that
light acts as a kinetic stimulus as well as a
directive one. When the individual is illum-
inated, therefore, its movement is determined
by the three factors operating simultaneously.
If light acts in opposition to gravity the rate
of upward crawling of the fly is lowered; and
if light acts with gravity the rate is increased.
Since the stimulus of gravity is always con-
stant, and the photokinetic stimulus constant
within wide limits, the rate of upward crawling
is a measure of the effect of the phototropice
stimulus.
Definite quantitative results have been ob-
tained by measuring with a stop-watch the time
necessary for wild flies to crawl to the top of a
glass cylinder under three different intensities
of light. Illuminated from above with a light
of 1,500 candle meters the time taken for 50
per cent. of the experimental flies to reach the
top (a distance of 172 mm) was found to be
6.17 seconds. With an intensity of 750 ¢.m.,
7.6 seconds; and with an intensity of 75 ¢.m.,

10.89 seconds. Each of these determinations
is the average of 50 trials with 87 animals
selected from five different cultures. The age
of the flies varied between six and nine days.
Under the illumination of a ruby lamp giving
only enough light to enable observation, the
time consumed in reaching the top was 11.3
seconds. There is then a definite relationship
between the intensity of illumination and the
rate of movement, which may be expressed by
the Weber-Fechner law, as was done in the
case of the Japanese beetle.1 Figure 1 ex-

presses this relationship. The broken line is
obtained by plotting the logarithm of the inten-
sity against the rate of locomotion, where rate
equals 100 divided by the reaction time in sec-
onds. From.this graph it may be concluded
that the sensation is proportional to the log-
arithm of the intensity of the stimulus. The
continuous line is obtained by plotting the reae-
tion time in seconds against the intensity of
light and leads to the same conclusion.
It was found by McEwen? that the mutants

of Drosophila known as white and vestigial
show variations from the reactions of wild
flies to light. He decided that the vestigial flies
are not oriented by light, a conclusion appar-
ently verified by experiments in which wild
flies, whose wings had been removed, were used.
The white race oriented positively to light, but
with less regularity and precision. In my ex-
periments it was also found that white flies are
less precise in their photic orientation, it being
many times impossible to secure satisfactory
readings on 50 per cent. of the individuals,
since after reaching the top of the cylinder
some would crawl back to the bottom, even
under an intensity of 1,500 em. No results,
therefore, are presented for the whites. In the
ease of vestigial flies it was found that a me-
chanical factor retarded orientation. When the
glass cylinder was used for these flies it was
discovered that the reason they did not reach
the top was because they continually lost their
foothold, when part way up, and fell back to
the bottom. This also happens with wild flies
whose wings are normal, but immediately the
wings are spread and the animal secures a new
foothold very near where he was before. The
upward movement is then continued, very little
time having been lost. This difficulty with
vestigials was removed by lining the cylinder
with very thin Japanese rice paper. This may
easily be done by moistening the paper, press-
ing it against the glass and allowing it to dry.
With paper-lined cylinders the vestigial flies
are strongiy phototropie and reach the top in
almost the same time as wild ones. The results
are as follows: with illumination of 1,500
candle meters the time was 6.81 seconds; with
750 e.m., 7.92 seconds; and with 75 ¢m., 11.1
seconds. In darkness the time for vestigials
was 12.2 seconds. From this data it is evident
that vestigial Drosophila is positively photo-
tropic, the degree being only shghtly less than
in wild flies, as measured by the rate of locomo-
tion. Some of this difference is undoubtedly
due to the aid rendered by the flying of the
wild individuals, although, as far as possible,
all cases of extended flight were omitted from
the averages!
Tt may be stated, therefore, that the effect of
light on the locomotion ot Drosopiila me-

lanogaster is related to the intensity of the
photic stimulus according to the Weber-
Fechner law, and secondly that the race of
flies known as vestigial is positively photo-
tropic, and may be demonstrated as such if
the animals are given a rough surface on which
to crawl.

THE STRUCTURE OF BENZENE
THe writer has shown, in his thesis for the
master’s degree? and in an article soon to be
published, that the benzene model first pro-
posed by Korner,? and later advocated by
Marsh,? Vaubel,t and others, interpreted in
the light of the Lewis theory of the atom,° has
a sound theoretical basis. By applying a theory
of conjugation resembling in many respects
that presented by Erlenmeyer, Jr., in 1901,°
all objections to this benzene structure but
one—that ortho and meta di-substitution
products should, according to the theory, give
stereoisomers which have not yet been re-
solved—have been removed.
In this model the six carbon tetrahedra have
their bases all in the same plane, the hydro-
gen atoms and the points of the tetrahedra
to which they are bonded being alier-
nately above and below this plane. There
are six electrons grouped around the center of
each hexagon, and two at each of the hexagon
corners and en the centerlines between each
hydrogen and the carbon to which it is-bonded.

author has shown that the structure of graphite,
as determined by X-ray analysis,® is exactly
what would be obtained if it were built of
layers of benzene hexagons of the type just
described, the carbon-hydrogen bonds of the
benzene molecules being replaced by carbon-
carbon bonds between the layers. Such an
arrangement not only accounts for the sym-
metry of the substance and for the observed
spectra, but also for its known chemical and
physical properties.
There are quite a number of aromatic com-
pounds, ineluding benzene itself, in erystals of
which, according to the author’s conjugation
theory, we might expect the molecules to be in
layers of much the same type as the layers in
graphite. Assuming this to be the case, if the
densities, axial ratios and axial angles are
known, the dimensions of the hexagon in these
erystals can be caleulated. This has been done
for a considerable number of substances, and
in every case in which large distortions would
not be expected, due to substituted groups, the
dimensions of the hexagon are very close to the
corresponding dimensions in graphite. If this
result were obtained for one or two erystals, it
might be considered merely a coincidence, but
it is found to be general; the dimensions are
found to correspond best where least distortion
would be expected; and the axial ratios and
angles, and the erystal form, symmetry and
cleavage, as well as the actual distances, are
found to conform to the structures assumed.
Hence this structure for the benzene nucleus
must be considered proved.
This method of proof was reported on by
the author in a paper presented at the twenty-
fourth special meeting of the California Sec-
tion of the American Chemical Society, held in
conjunction with the annual meeting of the
Pacific Division of the American Association
for the Advancement of Science, at Berkeley,
California, on August 5, 1921, at which time

triphenyl carbinol were used as examples. The
density of solid benzene was not then to be
found in the literature. This is now obtainable,
and from it and the axial ratios, by assuming
close packing of the molecules in each layer,
the hexagon dimensions can be computed. They
again check with those in graphite.
A paper is now being prepared in which the
method of proof and its application to a large

THE AMERICAN ASSOCIATION FOR
THE ADVANCEMENT OF SCIENCE
MEETING OF THE EXECUTIVE COMMITTEE
OF THE COUNCIL
THE spring meeting of the executive com-
mittee was held in the board room of the
Cosmos Club, Washington, D. C., on April 23.
It was ealled to order at 4:10, with Dr. Simon
Flexner in the chair and with all members
present, and it adjourned at 11:30, a recess of
an hour and a half having been taken for
dinner. The main items considered are shown
below.
(1) Minutes of the last meeting (December
31, 1922), and of two actions taken by mail
ballot in the interim were approved. These
interim actions were (1) the formal vote to
authorize the summer meeting with the Pacific
Division, which is to occur on June 22-24, at
Salt Lake City, and (2) the election of Dr.
J. Mek. Cattell to sueceed himself as a member
of the Board of Science Service.
(2) The permanent secretary presented a
report on the affairs of the association for the
half-year ending March 31. A summary of
that report is appended to the report of this
meeting.
(3) It was voted that all members of the
American Medical Association who are not
already members of the American Association
for the Advancement of Science may become
members of this association without the pay-
ment of the usual entrance fee ($5). The
A. A. A. §. is unable each year to invite all
June 23, 1922
new members of the A. M. A. to join the more
general association, as they have the privilege
of doing according to the rules for affiliated
societies of the A. A. A. §., and the special
privilege is now made general to all members
of the A. M. A., without reference to when
they joined.
(4) It was voted that the permanent secre-
tary should prepare an invitation letter to be
sent (about October 1) to each member of the
American Medical Association resident in New
England, Iowa and Oregon, asking him to be-
come a member of the American Association for
the Advancement of Science if he is not already
a member; these special invitations are to be
signed by the president of the American Asso-
ciation for the Advancement of Science (Dr.
J. Playfair MeMurrich), the chairman of the
Bxecutive Committee of the Council (Dr.
Simon Flexner), the permanent secretary and
several others. It is planned that a special
invitation of this kind shall be sent to other
American Medical Association members resi-
dent in other regions next year, ete., the entire
list of the Medical Association being cared for
in perhaps four or five years.
(5) The budget for the current year was
increased by the following items: Salaries,
$180; printing, $520; summer meeting, $500.
(6) The permanent secretary was asked to
secure good, readable reports of the meetings of
all sections and of their related societies at the
fourth Boston meeting, to have these published
in Science about the last week of January,
1923, and to have this special issue of the jour-
nal sent to all members who do not receive
Science regularly. The retiring president’s
address is to be published in the first issue of
Science after the meeting, and reprints of this
are to be made available, on request, to mem-
bers who do not regularly receive the journal.
It is planned that members in good standing
who do not attend the annual meeting may
recelve copies of the general program, if they
request them from the permanent secretary’s
office before the meeting.
(7) The making of arrangements for a speak-
er for one of the evening sessions of the sum-
mer meeting at Salt Lake City was referred to
the general secretary with power.
(8) Dr. D. T. MacDougal reported that the
SCIENCE

committee on Cooperation with Mexican Men
of Science recommends that Dr. E. L. Hewett,
of the School of American Research, Santa Fé,
N. M., be appointed special commissioner to
consult with officials of the Mexican govern-
ment regarding the organization of Mexican
men of science. Dr. Hewett was appointed and
was requested to serve the association in this
capacity on his forthcoming trip to the City
of Mexico. A committee consisting of Drs.
Howard and MacDougal was instructed to pre-
pare a suitable letter of credentials for the use
of Dr. Hewett, this to be addressed to the
Secretario de Agricultura y Fomento, to be
engrossed, and to bear the seal of the associa-
tion.
(9) It was voted that the expenses of the
Committee on Grants be paid from the funds
in charge of the permanent secretary.
(10) Dr. T. Wingate Todd, Western Reserve
University, Cleveland, Ohio, was elected vice-
president for Section H (Anthropology).
(11) Dr. Bird T. Baldwin, Iowa Child Wel-
fare Research Station, State University of
Iowa, Iowa City, was elected vice-president for
Section Q (Edueation).
(12) The election of Dr. S. C. Prescott as
chairman of the local committee for the fourth
Boston meeting was ratified.
(13) Thirty-three members were elected to
fellowship, on proper nominations.
(14) The resignation of Mr. Herbert A. Gill,
auditor of the association, was accepted with
regret, and with great appreciation of the very
valuable services he has given the association
in past years, and the permanent secretary was
instructed to secure an auditor, preferably a
well-known scientist, the clerical expense to be
met by the permanent secretary’s office.
(15) The Committee on Convocation Week
was completed so that it is constituted as fol-
lows: Dr. J. McK. Cattell, Garrison-on-Hudson,
N. Y., chairman; Dr. E. H. Moore, University
of Chieago, Ill.; Dr. J. P. MeMurrich, Univer-
sity of Toronto, Toronto, Canada; Dr. H. S.
Jennings, Johns Hopkins University, Balti-
more, Md.; and Dr. Edwin B. Wilson, Massa-
chusetts Institute of Technology, Cambridge,
Mass.
(16) The Canadian Society of Technical
Agriculturists was constituted an affiliated soci-
682
ety of the association. Its officers are: Pres?-
dent, Mr. L. S. Klinck, University of British
Columbia, Vancouver, Canada; secretary, Mr.
Fred H. Grindley, Gardenvale, P. Q., Canada.
(17) The Executive Committee reaffirmed
the desirability of holding the 1925 meeting in
Kansas City, and expressed its appreciative
thanks to the persons and organizations from
whom invitations to meet in that city have been
received.
(18) The policy of Section N (Medical Sci-
ences) was approved, by which it is planned
that the program of this section, at the annual
meeting, shall deal with such fields of work as
parasitology, medical entomology, public health
service, and others, where many medical scien-
tists have common interests with those working
in other fields of biology.
(19) A committee was appointed, consisting
of the president, the general secretary and the
permanent secretary, to arrange for the send-
ing of delegates to the Hull meeting of the
British Association for the Advancement of
Science.
(20) The proposed federation of biological
societies was considered at length, and the com-
mittee expressed itself as in sympathy with
the general aims of the societies involved. The
hope was expressed that the organization of
the association may be of service to the new
federation.
(21) The controversy aroused by recent pop-
ular publications regarding the theory of evolu-
tion was considered, and a committee of three
was appointed to deal with this matter and
make recommendations at the meeting of the
executive committee. The committee on the
evolution controversy consists of Dr. Edwin G.
Conklin, Princeton University; Dr. C. B.
Davenport, Station for Experimental Evolu-
tion; and Dr. Henry Fairfield Osborn, Amer-
ican Museum of Natural History, New York
City.
(22) The permanent secretary was asked to
secure manuscripts for the general program
for the fourth Boston meeting as early as may

PERMANENT SECRETARY’S REPORT FOR
THE HALF-YEAR ENDING MARCH 31, 19221
Tue last volume of the Summarized Pro-
ceedings, published in October, 1921, is now
nearly out of print. The total cost of publica-
tion was $6,744.16 and sales have amounted to
$2,587.00, making the net cost, at the present
accounting, $4,157.16. The volume is being
sold to members for $2.00 and to others for
$2.50. Fifty copies remain to be sold, besides
twenty copies reserved for complete sets.—
A booklet of information for prospective new
members, which contains a statement of the
organization and work of the association, was
published in January. Copies may be secured
from the permanent secretary’s office—The
resolution regarding the United States Forest
Service, adopted at the recent Toronto meeting,
was printed as a leaflet and sent to all members
of Congress and to other officials.
Invitations to join the association have been
sent to 28,303 persons, of whom 830, or 3.4
per cent., have already joined. From Septem-
ber 30, 1921, to March 31, 1922, 1,111 new
annual members and 9 new life members have
been enrolled, and 22 members have been rein-
stated; the total gain was 1,142. During the
same period 67 deaths were recorded, and 265

resignations, and 705 names were dropped
(October 1) because of over two years of ar-
rearage); the total loss was 1,037. Four mem-
bers were transferred from annual to life mem-
bership. The net gain in total membership,
for the half-year, is 105. The membership data
for the last year and a half are tabulated
below:

t is elear that the membership is gradually
increasing, but there still remajn many persons
in the United States and Canada who are vitally
interested in scientific and educational progress
but who are not yet enrolled in the association.
Members of the association should do all in
their power to increase the membership and
thus strengthen the organization.
A local branch of the association was organ-
ized in the fall of 1921 and is in successful
operation. This is the State College (Pennsyl-
vania) Local Branch. Its officers are: chair-
man, A. J. Wood; secretary, J. Ben Hill. It
has an enrollment of 53 members of the asso-
ciation. Fifteen new members have been
secured through its activities. The State College
Branch holds occasional meetings throughout
the year.
Plans for the summer meeting of the asso-
elation, jointly with the Pacific Division, which
is to oceur at Salt Lake City, June 22-24,
1922, are progressing satisfactorily. Details
of these plans are in charge of Mr. W. W.
Sargeant, Golden Gate Park, San Francisco,
secretary of the Pacific Division, and the gen-
eral secretary of the association, Dr. D. T.
MaeDougal, Carmel, California. The chairman
of the local committee for the Salt Lake City
meeting is Professor H. G. Titus, 215 S. Third
Kast, Salt Lake City, Utah.
Card lists of all the members enrolled in each
section of the association have been prepared
and will soon be in the hands of the secretaries
of the respective sections, together with a steel
cabinet for each set of cards. These section
lists will be Eept continually corrected, by

means of cards sent out from the permanent
secretary’s office. Hach member’s addressograph
plate now shows, besides his name and address
and the formula of his membership status, one,
two, or three letters denoting the section or sec-
tions in which he is enrolléd. Thus, ABD indi-
cates that the member on whose plate this letter
combination appears is enrolled in Sections A,
B and D, and a corresponding card is found in
each of the three section lists. When a member
has indicated more than three sections as his
preferences, the first three on his list have been
indicated on the plate. In cases where no sec-
tion has been named by a member, it has been
impossible to enroll him in any particular sec-
tion, and he is regarded as a member of the
association in general. When members receive
cards, ete. from the permanent secretary’s
office, they are requested to serutinize the ad-
dressograph impression and inform the office
if any corrections are needed with respect to
their section enrollment.
Financially, the association is more than
holding its own. The permanent secretary’s
reserve or emergency fund amounted (on
March 31) to $5,855.09, $1,500 having been
transferred to this fund on March 25. Of this,
$1,000 is specially reserved from the eurrent
funds of 1922 for meeting the extra expense
of publishing the next volume of Summarized
Proceedings, which is to appear in the spring
of 1925, following the next four-yearly (Wash-
ington) meeting. After all liabilities are cared
for, over $2,000 is available (March 31, 1922)
for appropriation from the current funds of
the present fiscal year, which ends October 1
1922.

SECTION M—ENGINEERING AND ASSO-
CIATED SOCIETIES
THE resuscitation of Section M at the recent
Toronto meeting of the American Association
for the Advancement of Science resulted in a
program of considerable length and much
diversity. The attendance was good, and the
interest was sustained to the end. Sir Clifford
Sifton, formerly chairman of the Commission
of Conservation, Canada, gave the opening ad-
dress on Tuesday afternoon, his subject being
“Some Views on the Development of the Nat-
684
ural Resources of Canada.” He dealt, among
other things, with the fuel problems of Canada
in their relation to the development of hydro-
electric power, and with the general conditions
obtaining at the present time in the rural dis-
tricts.
Papers by Paul Heymans, now of the Mas-
sachusetts Institute of Technology, and Profes-
sor Charles Mannebeck, of the University of
Louvain, Belgium, on “Optical Determination
of Stress in Engineering Structures” and “Re-
turn Current along Submarine Cables,” re-
spectively, were read by the authors.
At the morning session on December 28, Mr.
John Murphy, electrical engineer for the De-
partment of Railways and Canals, Ottawa, gave
an address on “Ice Formation and Prevention
with Special Reference to Frazil and Anchor
Ice.” Mr. Murphy advocated keeping certain
metal parts of hydro-electric installations a
small fraction of a degree above 32°F. with
the aid of artificial heat. This can be and is
being done at certain plants on the Ottawa
River to which Mr. Murphy made reference.
“Wneineering Standardization” was discussed
by Ma. R. J. Durley, secretary of the Canadian
Engineering Standards Association. Other
papers were “Fifty Years of Progress in Min-
ing in Canada” by Mr. John HE. Hardman,
“Metal Mining in Canada,’ by Thomas W.
Gibson, deputy minister of mines, Ontario;
“Gold Mining in Canada” by Mr. A. F. Brig-
ham and “Nickel Mining and Smelting” by
W. L. Dethloff, chief engineer of the Mond
Nickel Company.
The morning session on Thursday, December
29, was given over to an illustrated address on
“Toronto Harbor Development” by Mr. George
Clark, chief designing engineer of the Toronto
Harbor Commission, and to a discussion on
Scientifie and Industrial Research by Dr. R. A.
Ross, chairman of the Honorary Advisory
Council for Scientific and Industrial Research,
Canada, who emphasized the economic import-
ance of obtaining a satisfactory method of car-
bonizing the lignites of Western Canada. Mr.
H. K. Wicksteed read a paper on “Railway
Development in Canada” treating his subject
chiefly from an economic standpoint. In the
afternoon Messrs. A. M. McQueen and James
SCIENCE
[Vou. LV, No. 1434
McEvoy read papers on “Exploration for Oil in
Western Canada” and “Coal Mining in Al-
berta” respectively. Sir Adam Beck, chairman
of the Hydro-Electrie Power Commission of
Ontario, gave in Convocation Hall an address
to all sections of the American Association for
the Advancement of Science in the afternoon
at 4 o’clock. This address was well attended
and was illustrated by motion pictures. Sir
Adam drew a comparison between the cost of
Niagara generated hydro-electric energy in
Windsor, Ont., and steam generated electric
energy in Detroit, Mich., the prices being 314
and 8 cents per kilowatt hour, respectively.
The Friday sessions, with the exception of
Mr. D. B. Dowling’s address on the Mackenzie
oil fields, were given over to the discussion of
problems pertaining to Engineering Education.
Works Commissioner Harris, City of Toronto, -
gave the employer’s viewpoint with respect to
the qualifications of the young engineer.
Professor Charles F. Scott, president of the
Sogiety for the Promotion of Engineering
Education, contributed a paper on “Pro-
fessional Engineering Education for the
Industries.” Dr. F. W. Merchant, director of
industrial and technical education, Ontario, ad-
dressed the section on the, function of the sec-
ondary technical school. Professor Dugald C.
Jackson’s paper on the same subject was read
by Professor C. R. Young in the absence of
the author. Discussion following all of these
papers was very general.
Regarding the sessions of the Society for the
Promotion of Engineering Education, held at
Toronto on December 30, 1921, the reader is
referred to the Canadian Engineer, Vol. 42, No.
1, p. 109, Jan. 3, 1922, and Vol. 12, No. 2, p.
133, Jan. 10, 1922.
The closing function was a dinner in Hart
House on Friday evening at which one hundred
were present. Mr. J. B. Tyrrell, chairman of
the section, presided at all sessions. The com-
mittee in charge of arrangements consisted of
the chairman, Mr. Tyrrell, and Professors R.
“ W. Angus, Peter Gillespie and C. R. Young,
all three of the University of Toronto.

THE RELATION OF THE ENDOCRINE
GLANDS TO HEREDITY AND
DEVELOPMENT!
Since the object of the Eugenics Research
Association is the advancement of knowledge
that will contribute to the improvement of the
human race by inheritance, its members can
searcely fail to be interested in the discussions
that are now going on regarding the glands of
internal secretion and their relations to hered-
ity. As a medical man, deeply interested in
the problems of constitution and of condition
and profoundly impressed with the recognizable
influences of internal secretions upon form and
function in both normal and pathological states,
I welcomed the suggestion of Dr. Davenport
that I deal in my presidential address with the
topie announced. The progress of research in
endocrine domains and in heredity has of late
been so rapid that no single person can keep
pace with its strides. My remarks, therefore,
will make no pretence to completeness of dis-
cussion of the reciprocal relations of heredity
and endocrinology. They are intended rather
to direct the attention of the members of the
association to some of the more important facts
that have been established and to stimulate
interest in some of the newer problems that are
emerging and clamoring for solution.
THE ENDOCRINE ORGANS AND THEIR PRODUCTS
It is only comparatively recently that the
significance of the so-called ductless glands and
of the substances they manufacture has become
recognized, but, in a very short time, a consid-
erable body of knowledge concerning their
structure, their functions and their inter-rela-
tions has been accumulated. At the moment,
studies of the internal secretions, or, as many
now call them, the “inecretions,” are, on ac-
1 Presidential address at the tenth annual meet-
ing of the Eugenies Research Association, held at
Cold Spring Harbor, Long Island, June 10, 1929.

count of their astonishing and novel revela-
tions, attracting the attention not only of
scientifie workers in biology and medicine but,
and perhaps to too great an extent, also of the
laity. Important as a knowledge of these
incretions is for an understanding of bodily
and mental states, there is some danger, I think,
of over-emphasis and of disproportionate
prominence. Popular articles and treatises on
endocrine subjects too often assume what is
mere conjecture, or wild speculation, to be
established as fact and reveal a tendency to
exploitation that must sooner or later be fol-
lowed by disappointment and disillusionment.
There is, I fear, some danger that even seien-
tifie endocrinology may, temporarily at least,
be brought into undeserved discredit. It would
seem especially desirable, therefore, that those
who write or speak upon the subject should
discriminate carefully between fact and fancy.
Hyery effort should be made rigidly to control
hypotheses by accurate observation and careful
experiment, for only thus can an orderly ad-
vance in knowledge be assured.
Though an ineretory function has been
ascribed to many organs of the body, the prin-
cipal ineretory organs, those whose function is
best understood, are seven in number: (1) the
thyroid gland, (2) the parathyroid glands,
(3) the hypophysis cerebri, or pituitary gland,
(4) the epiphysis cerebri, or pineal gland,
(5) the suprarenals (consisting of two parts of
entirely different functions, (a) the medulla or
chromaffine portion and (b) the cortex or inter-
renal portion), (6) the islands of Langerhans
of the pancreas, and (7) the interstitial tissue
of the gonads (ovaries and testicles) or so-
called “puberty gland.”
There is evidence that each of these organs
yields an internal secretion that, distributed
through the blood, exerts important chemical
influences upon other, more or less distant,
organs and tissues. Some of these influences
have been definitely determined, but it will
doubtless be a long time before all of them will
be well understood. The knowledge that has
been gained concerning the thyroid, the pitu-
itary, and the suprarenals gives promise, how-
ever, that steady research will gradually en-
large our information regarding the influences
exerted by each of the incretory glands.
SCIENCE
[Vou. LV, No. 1435
The chemical substances contained in the
incretions have been ealled “hormones” and the
determination of the precise chemical constitu-
tion of these hormones sets fascinating tasks
for the biochemist. That the chemical consti-
tution of some endocrine products may be
closely approached, if not definitely estab-
lished, has been shown by researches upon
epinephrin (from the medulla of the supra-
renal gland) and upon iodothyrin and thyroxin
(from the thyroid gland). Studies of concen-
trated functionally potent extracts from other
glands may before long reveal the chemical
nature of other hormones; I have in mind,
especially, studies of so-called “pituitrin”
(hypophyseal extract) and of so-called insulin
(extract of the islands of Langerhans of the
pancreas). Clues as to the chemical nature of
the hormones of the parathyroids, the pineal
body, the interrenals and the gonads will prob-
ably be more difficult to obtain. Biochemical
researches to establish the precise nature of the
single hormones are extraordinarily important
and should be vigorously prosecuted in order
that experimental studies of hormone influ-
ences may be more systematically, exactly and
intelligently pursued.
THE BETTER-KNOWN ENDOCRINOPATHIES
Our knowledge of endocrine functions has
been variously derived, partly through
keen clinical-pathological observations, partly
through experimental work upon animals (sur-
gical removal of single organs; organ trans-
plantations; injections of organ extracts or of
isolated hormones). Before discussing the
relations of the endocrine organs to heredity
and development, it may be helpful briefly to
refer to a few of the classical clinical syn-
dromes that are now justifiably believed to be
endocrinopathic in origin. Time will not per-
mit me to refer to more than a few of these,
but those chosen will serve as illustrative
paradigyas.
I may cite first two characteristic clinical
syndromes met with in association with disease
of the thyroid gland, namely, exophthalmic
goitre and myxedema.
In the former, known also as Graves’ disease
or Basedow’s disease, we observe, in typical
instances, a markedly enlarged pulsating thy-
JUNE 30, 1922]
roid gland (goitre) in the neck, a persistently
accelerated pulse rate (say 150 or more to the
minute instead of the normal rate of 72),
marked nervous symptoms including fine tremor
of the fingers, outspoken protrusion of the eye-
balls (exophthalmos), a tendency to profuse
sweats and to watery diarrhcea, sensitiveness to
heat, a peculiar psychic over-alertness and
apprehensiveness, and a tendency to rapid ema-
ciation (despite an abundant food intake)
associated with demonstrable acceleration of
the rate of the basal metabolism. Since simi-
lar symptoms can be produced by feeding
thyroid gland extract, it is believed that there
is a hyperfunction of the thyroid gland (hyper-
thyroidism) in exophthalmie goitre.
In the idiopathic form of myxedema (or
Gull’s disease) the clinical conditions are dia- .
metrically opposite to those in exophthalmic
goitre. The thyroid gland is small, the puise-
rate is usually slow, the eyes look sunken
(enophthalmos), the lid-slits are narrow, the
bodily movements are slow and clumsy, the
patient is mentally dull, forgetful and apa-
thetic, there is sensitiveness to cold and a ten-
deney to constipation, the hairs fall out, the
skin is dry, thick and wrinkled and there is a
tendency to obesity (despite a restricted food
intake) associated with demonstrable retarda-
tion of the rate of the basal metabolism. Since
patients with idiopathic myxedema rapidly
improve if they are fed the thyroid giand of
the sheep, and since a condition precisely sim-
ilar to it oceurs if the thyroid gland be sur-
gically removed (cachexia thyreopriva), it is
believed that myxedema is due to a hypofune-
tion of the thyroid gland (hypothyroidism).
Two sumilarly contrasting clinical syndromes
due to disorders of the hypophysis cerebri or
pituitary gland may next be mentioned, namely,
(1) gigantism and acromegaly, due to over-
function, and (2) Froehlich’s syndrome of
obesity with genital dystrophy, due to under-
function.
When there is overfunction of. the pituitary
gland in early life before the epiphyses of the
long bones have united with the shafts of those
bones there is over-stimulation of bony growth
and the patient becomes excessively tail (gigan-
tism). When the overfunction of the pituitary
SCIENCE
687
gland occurs in later life (after epiphyseal
union), bony overgrowth is still stimulated but
manifests itself in enlargement of certain parts
of the skull and of the hands and feet
(acromegaly). There is also enlargement of
the tongue and of the internal organs (splanch-
nomegaly). The vietim presents a very char-
acteristic appearance. The face is hexagonal,
the nose is broad, the chin is prominent and
curved so as to bend sharply upward, the cheek
bones are outstanding and the arches above the
eyes are prominent. Looked at from the side,
the face resembles that of Punch (nut-cracker
profile). The hands are spade-like, the fingers
are sausage-shaped, and the feet are huge.
On the other hand, when there is under-
function of the pituitary gland during develop-
ment a condition (Froehlich’s syndrome) in
marked contrast to gigantism and acromegaly
results. The skeletal development is defective,
the growth of bone being less than normal.
The patient is short in stature, the face re-
mains child-like and the hands and feet are
small (acromikria). The subcutaneous fat is
markedly increased (obesity), and is distributed
in an uneven way over the body, being most
abundant on the abdomen, over the buttocks,
and in the proximal portions of the extremi-
ties. The secondary sex characters either fail
to develop or develop in a faulty way. The
pubic and axillary hairs do not appear or are
seanty. The external genitals remain in an
infantile state. In young men the voice is high
pitched and there is a lack of normal virility.
In young women, the menstrual flow is scanty
or absent.
Next, let us contrast two clinical pictures
believed to depend upon disorders of the supra-
renal capsules, (1) Addison’s disease, met with
in destruetion of the suprarenals (hyposupra-
renalism), and (2) pseudo-hermaphrodism,
premature puberty, and hirsutism, met with in
association with hyperplasias of the supra-
renals (hypersuprarenalism).
In Addison’s disease there is great weakness
and prostration, associated with low blood
pressure, diarrhea and other digestive dis-
turbances, chronic anemia and often a peculiar
bronzing of the skin (melanoderma).
On the other hand, in cases in which there is
688
believed to be overfunction of the suprarenals,
the clinical picture is markedly different though
it varies somewhat with the time of onset of the
assumed hyperfunction. Should this occur
during fetal life, a pseudo-hermaphrodite ap-
pears, the person presenting the external gen-
ital appearances of one sex while possessing
the internal sex organs of the other sex. When
the overactivity exists soon after birth rather
than before birth, puberty appears premature-
ly, a little girl of three or four menstruating
regularly and exhibiting the bodily and mental
attributes (sexually) of an adolescent, or a
boy of seven presenting the external genitals
and the secondary sex characters of an adult.
Should the overactivity of the suprarenals not
occur until adult life, it may reveal itself in a
woman of middle age by the rapid develop-
ment of hairiness over the body (hirsutism)
and by the exhibition of masculine character-
istics (virilism).
Other examples of clinical pictures might be
mentioned but these few will suffice to illus-
trate the extraordinary mental and physical
changes that may become manifest when there
are disturbances of function of the endocrine
organs.
CONSTITUTION AND THE ENDOCRINE ORGANS
Biologically considered, a developed human
being, like all developed higher organisms,
must be looked upon as the resultant of a long
series of reactions between the zygote (fer-
tized ovum) and its environment. The ger-
minal type or genotype, reacting with the sur-
roundings, becomes the developed type or
phenotype, in the case of human beings, the
“realized person.” The germ plasm provides
the determining factors, the environment the
realizing factors. Everything in the phenotype
attributable to inheritance may be spoken of
as “constitution,” everything attributable to
environment as “condition.” Medical men as
well as biologists must, then, when studying a
person or a single organism, be interested in
differentiating, when they can, what is “consti-
tutional” from what is “conditional” in origin.
In experiments upon animals and plants such a
differentiation may be relatively easy; in
studies of human beings it is always extremely
SCIENCE
[Vou. LV, No, 1435
difficult and, as regards many features, as yet
wholly impossible.
The importance of constitution will need no
emphasis among biologists who are predom-
inantly students of heredity. Among medical
men, too, throughout the centuries, especially
among practitioners, there have always been
those who have been fully aware of the sig-~
nificance of constitution and of its relation to
disease-disposition. During the past fifty
years, however, under the spell of bacterial
and protozoan etiology, medical men have been
so absorbed by studies of influences arising in
the environment that they have, too often, for-
gotten to continue their investigation of influ-
ences of endogenous origin. For a time, it was
almost taboo to speak of “constitution,” or of
“disposition,” owing to a justifiable reaction,
perhaps, against the earlier prevalent tendency
to use these words as a mask for ignorance.
Recently, however, there has been a welcome
revival of studies of constitution. Now that
facts that supply a scientific basis for a general
pathology of constitution have been aceumu-
lated, we may look forward to a greatly
increased interest among physicians in the part
played by inheritance in disease.. Indeed,
during the past five years, several treatises
upon this and allied subjects have been pub-
lished; and we may expect, I think, during the
period just ahead of us, many attempts to
present, more systematically than hitherto, the
role played by constitutional disposition in
the pathogenesis of a whole series of diseases.
The chemical consideration of endocrine dis-
orders, has in my opinion, given a strong im-
petus to this movement toward a revival of
studies of the physiology and the pathology of
constitution. For though the endocrine organs
are, in some instances, accessible to trauma and
to poisons and parasites that reach them
through the blood-stream, diseases of these
organs, especially those “idiopathic” chronic
diseases that develop insidiously and give rise
to the classical endocrine syndromes, appear
to be, usually, of endogenous rather than of
exogenous origin, that is to say, they develop
as the results of special anomalies of constitu-
tion. This accounts for the fact that endo-
crinopathies tend to run in families, and the
JUNE 30, 1922]
interrelationships that exist among the different
endocrine organs may explain why a disease
of the thyroid (exophthalmie goitre) may ap-
pear in one member of a family, a disease of
the pancreas (diabetes mellitus) in another, a
disease of the hypophysis (dystrophia adi-
posogenitalis) in a third, or a pluriglandular
disorder in a fourth member of the same fam-
ily. The experienced clinician can now often
recognize phenotypes in which there are
anomalies of constitution that predispose to
- endocrine disorders; and as a result of this
recognition he may, sometimes, be able to insti-
tute a rational prophylaxis. The thyreotoxie
constitution, the hypothyreotice constitution, the
hypoparathyreotic constitution, the hyper-
pituitary constitution, the hypopituitary con-
stitution, the hypergenital constitution and the
hypogenital constitution are instances in point.
Unfortunately we have not learned as yet how
effectually to intervene in a prophylactic way
in all of these anomalies of constitution, but
rewarding experiences with the hypothyreotie
and with the hypoparathyreotie constitution
give us hope that, with widening knowledge,
suitable preventive measures will be discovered.
Studies of the symptoms of endocrine dis-
orders and studies of partial anomalies of con-
stitution affecting the endocrine organs are thus
throwing much light not only upon (1) the
mode of action of the ineretions, but also wpon
(2) inheritance as a determining cause of endo-
erinopathic phenotypes. The incretions may
affect distant parts directly, being carried to
them by the blood; or they may affect those
parts indirectly through the intermediation of
the autonomic nervous system, which they sen-
sitize. When they act directly, they may influ-
ence the substances and processes in the locali-
ties that they reach (chemical correlation; reg-
ulation of metabolism) or they may supply
materials for incorporation by the cells (nutri-
tive and formative influences). When they
act indirectly through the vegetative nervous
system they may exert profound effects
through the secretory activity of glands,
through the contraction of smooth muscle, or
through modifications of those neural mechan-
isms that have to do with the emotions and
the will. During the developmental period, it
is clear that the incretions are in part responsi-
SCIENCE
689
ble for the dimensions and proportions of the
skeletal apparatus and the soft parts. A
normal functioning of the ineretory organs is
essential for the shaping of parts and for the
maturing of functions in the right place and
at the right time. Through correlative differ-
entiation (due in part at least to the action of
the ineretions), the developing organism gradu-
ally comes to exhibit the characteristics of its
species, its age and its sex. Even the anthro-
pologists now maintain that the solution of
the problem of how mankind has been demar-
cated into types so diverse as the Negro, the
Mongol and the Caucasian will involve the
study of hormonie mechanisms!
CAN HORMONES MODIFY UNFERTILIZED GERM-
CELLS SO AS TO INFLUENCE INHERITANCE
Thus far in our discussion of the relation of
the endocrine glands to heredity and develop-
ment we have confined our attention to (1)
the genotypic determination of endocrine func-
tions in developing organisms, (2) the réle
played by the incretions in normal and patho-
logical ontogeny, and (3) the fact that there
exist heredo-familial anomalies of body make-
up that predispose to endocrine disorders. But
we must, for a few moments at least, consider
the possibility that hormones, reaching unfer-
tilized germ-ceils, may modify the germ plasm
in such a way as to give rise to new inheritance
factors that will be transmitted from genera-
tion to generation.
Experiments upon the influence of ineretory
substances upon the development of cold-blood-
ed animals have yielded such striking results
upon cells of the soma that many have won-
dered whether ineretions circulating in the
blood might not also permanently alter the
germ-cells so as to account in animals for the
origin of mutations and new biotypes. You
will recall the experiments to which I refer
(1) the acceleration of tadpole metamorphosis
by feeding thyroid substance and (2) the re-
tardation of the same process by feeding thy-
mus substance.
In endocrine diseases of either endogenous
or exogenous origin, the cells of the soma are
also markedly altered; and the question has
naturally been asked, May not the germ-cells
be simultaneously profoundly changed?
690
Since 1895, a number of investigators have
suggested that the influence of specific internal
secretions might easily be used for the explana-
tion of the inheritance of acquired characters.
Last year, an English evolutionist published a
volume on “Hormones and Heredity” and sug-
gested that environmental influences infiuencing
an organ, or part, of the mother may set free
chemical substances (hormones) that, carried
through the blood to the ovaries, may affect
the ova in such a way as to lead to similar
changes in the same organ, or part, of the off-
spring. By such a mechanism he would attempt
to account for a progressive evolution in the
animal series. His theory would seem prac-
tically to be a modfiication of the pangenesis
theory of Darwin with the substitution of
“hormones” for Darwin’s “gemmules.”
Many physicians, too, have leaned toward
Lamarckian or neo-Lamarckian theories that
assume the inheritance of acquired characters
and some of these have suggested that in such
inheritance the ineretions must be concerned.
Those who have been trained in the methods of
modern biology, however, usually reject La-
marckism, and attempt to explain the apparent
inheritance of “acquired characters” for a gen-
eration or two by assuming either a “germinal
injury” (in the sense of Forel’s ‘“blastoph-
thoria”) or a “parallel induction.”
The consensus of biological opinion in this
country is strongly opposed to the inheritance
of acquired characters. Mendelian studies lend
no support to the view that conditional influ-
ences can affect inheritance factors. Mendelism
is, however, difficult if not impossible to apply
to man. As some one has put it, “the propa-
gation of man consists of a continual crossing
of polyhybrid heterozygote bastards,” not
susceptible to analysis by Mendelian methods
such as ean be applied to the study of the
propagation of plants and experimental ani-
mals. But if inheritance of acquired characters
really occurred, why should there not be, as
Conklin emphasizes, an abundance of positive
evidence to prove it? When one plant or
animal is grafted on another, there is no evi-
dence that the influence of the stock changes
the constitution of the graft. When an ovary
is transplanted, the foster mother does not
SCIENCE
[Von. LV, No. 1435
affect the hereditary potencies of the ova.
Until more proof has been brought than has
hitherto been advanced, we shall not be justi-
fied, so far as I can see, in accepting the
theory that conditional influences change
hereditary factors. There are, moreover, aside
from the problem of the inheritance of acquired
characters, enough relationships of the endo-
crine organs to heredity and development to
long keep us rewardingly occupied.
CONCLUSION
Let me summarize in a few words the situa-
tion as I see it. The endocrine organs are of
the greatest importance in normal development,
their ineretions exerting profound formative
and correlative influences. In pathological de-
velopment, the abnormal plenotypes that ap-
pear often point decisively to partial anomalies
of constitution involving especially the duct-
less glands and their functions. Whether or
not under normal or pathological conditions,
hormones arising in the soma can so change
the germ plasm of ova or sperm-cells as to ac-
count for certain mutations or for germ-cell
injury is a question that deserves considera-
tion and merits experimental test. Finally, the
conjecture that conditional influences upon the
soma can through hormonal production and
transportation to parental gametes so modify
the germ-plasm as to result in the inheritance
of the conditioned modification seems, as yet,
to have but little, if any, evidence to support it.

AN ANALYSIS OF STUDENT
GRADES AT WASHINGTON
UNIVERSITY SCHOOL
OF MEDICINE
THis work was undertaken with the idea of
obtaining some definite data upon which to
base opinions of students’ grades during their
medical course. As the data obtained were of
great interest to the staff of this school it was
thought advisable to publish them in order that
they might be used for comparison with those
of other schools.
The records of those students in the classes
of 1914, ’15, 717, 719, ’20 and ’21 who spent all
June 30, 1922]
four years of their course in Washington
University Medical School were studied. The
class records before 1914 were not complete
enough to average with the later records. The
class of 1916 had only two members who spent
all four years in this school, these records not
being complete, and the class of 1918 finished
its course in France, so these two classes were
not considered in the analysis. In the six
classes studied there were available the records
of 89 students. From these records were copied
the average for each year, the graduation age,
degree at matriculation, and the school in
which premedical training was taken.
In considering the graduation age of the
students it was found that there was little
variation from one year to another.
average graduation ages for the classes studied
beginning with that of 1914 were 25, 26, 2514,
26, 26, and 24 years, respectively. Thus the
average graduation age of the 89 students was
approximately 2514 years. The variation be-
tween individuals was so slight that no rela-
tion between age and grade was worked out.
The number of students possessing bachelor’s
degrees upon matriculation was 14, or 15.73
per cent. of those studied. Eleven were A.B.
degrees and three B.S. degrees. One might
have expected a larger percentage of bachelor
of science degrees from students interested

primarily in the sciences. The average gradua-
tion age of these students was 26.64 years, or
1.35 years older than that of those without de-
grees. The average grade of the group with
degrees was 82.21 per cent. as contrasted with
80.89 per cent. for that without degrees. Thus
we see that the average man with a degree
upon matriculation was 1.35 years older than
the man without one, but that his grade was
1.52 per cent. higher than that of the under-
graduate student. Is an increase of grade of
1.32 per cent. worth a time loss of 1.35 years
in a medical student’s career?
The grade averages by years for each class
are given in Table I. Here we see that there
is not much variation between the classes of
the years studied. This fact would indicate
that a uniform system of grading had been
used for all classes, providing the class of stu-

dent remained the same for each year. There
is a gradual increase in the general average
from the first to the fourth year of 4.69 per
cent. As the same students are present
throughout all four years, this either shows an
improvement in the student’s ability or, more
likely, severe grading during the first years or
lax grading during the last years of the course.
The general average of the entire group for all
four years is 81.10 per cent., which is a low B
grade in our letter system. This gives us a
numerical figure for our average students in
the future.
There was a great tendency toward variation
in the grades of an individual from one year
to the next. This is well shown in Table IT
in which the per cent. of students varying a
given percentage in grade, either up or down,
between the different years of the course is
shown. There is always a larger proportion of
the class showing an increase in grade as would
be expected from the increase in general aver-
age. To show how inconstant the grades are
from year to year we note that more than 36
per cent. of the students have a difference of
over 8 per cent. between first and fourth year
averages, and indeed, 3.62 per cent. show a
difference of over 18 per cent.
In Table III the rank of the student in his
class is considered. The men of each class
were arranged according to rank, based on their
first year averages, and the class then split into
thirds, an upper, middle, and lower third. Each
third was now considered 100 per cent. and
the upper represented by left diagonal lining,
the middle by cross hatching, and the lower by
right diagonal lining. The proportion of the
men of the upper third during the first year
who fell into the middle third the second year
is represented by the area of left diagonal
lining in the middle division under year II.
Similar changes in other groups may be fol-
lowed in the same manner. It is obvious that
aman might go from group 1 to group 2, then
back to group 1 the third year, so that the left
diagonal lining in group 1 for the third and
fourth years does not represent the percentage
of men who remained there constantly for four
years, but that portion of the men who started
in group 1 the first year who are there in the
SCIENCE
[Vou. LV, No. 1435
year observed. Therefore the interrupted line
was inserted in order to indicate the percentage
of men in each division who remained there
constantly for every one of the four years.
This table shows that the upper and lower
thirds of the class are the most constant in
their rank, for 36 per cent. remained in the
upper third constantly and 27 per cent. in the
lower, while only 10 per cent. of the middle
third remained there for four years. Those
students who drop from the upper to lower
third in the third year may be the ones pri-
marily interested in the fundamental sciences,
and not in clinical work. There are usually
one or two such individuals in each class. We
do get a surprising revelation of the incon-
staney of a large proportion of the class.
Only 24.7 per cent. of the group studied
remained constantly in one division for four
years, 57.3 per cent. went up or down one
division, and 18 per cent. up or down two

divisions during the course. This shows that
no class could have been even approximately
grouped for the entire course on the basis of
the first year’s averages.
Finally those men in the group who had
first year averages of less than 72 per cent.
were picked out. It was thought that these
were the borderline men, students who might
have been dismissed from school had their
grades been only one or two per cent. lower.
The object was to observe the further progress
of this group with regard to the other students.
There were 15, or 16.8 per cent., of the stu-
dents with a first year average under 72 per
cent. Forty per cent. of them had their pre-
medical training at Washington University, 40
per cent. at the smaller colleges, and 20 per
cent. at state universities.
At the end of the fourth year 40 per cent.
of these men had grades above the average
for the senior year, 20 per cent. ranked in the
upper third of the senior class, 27 per cent. in
the middle third, and only 53 per cent. in the
lower third. Of the 20 per cent. in the upper
third of the senior class, one third had pre-
medical training at Washington University, one
third at a small college, and one third at a
state university. The middle and lower thirds
were equally divided between the small colleges
and the universities. So it would seem that if
poor preliminary training were the cause for
the low first year average of these students we
must blame the universities equally with the
smaller colleges, for the percentage of advance
in grade was equally divided between students
from Washington University and such colleges
as Central, Missouri Valley, Southwestern,
and Christian Brothers’.
As almost 50 per cent. of these men who
might easily have been dismissed from school
on their first year’s record made mediocre and
even excellent students during their senior year,
the question arises as to how many of the men
with first year grades just below 70 per cent.
who are now dismissed from school might
reach the upper third of their class were they
allowed to remain. Can we say it would be
less than 20 per cent.? Yes, because many
questions are considered in giving a student a
grade just under or just over 70 per cent.,

amongst them being just this possibility of im-
provement. However, these figures should
make us in the future think even more carefully
before declaring a student unfit for the study
of medicine on the basis of his first year’s
record.

CHARLES BASKERVILLE
THe death of Charles Baskerville, last Jan-
uary, was a great calamity to the chemical pro-
fession. His end was premature—he was near-
ing 52 years of age—and it brought a poignant
sense of bereavement to his numerous friends.
He did not live to see his life’s work done, but
he departed from a world which will evermore
be the richer for having once had him.
Deeply and peculiarly American, an aristocrat
by birth, Charles Baskerville was nevertheless
broad and cosmopolitan in all his educational
work, and honored by his students, pedagogic
associates and professional colleagues. A man
of high quality whose poise and personality
early established leadership, his cheerfulness,
sympathetic helpfulness and constant produc-
tivity brought the admiration and respect of all
who had the privilege of being near him.
For thirty years Charles Baskerville occupied
a prominently successful position in chemical
education (University of North Carolina, his
alma mater, 1891-1904; College of the City of
New York since 1904); but, in addition, he
found time for the conduct of original re-
searches of value (first on the rare earths and
later on the chemistry of anesthetics), while his
inventions in the refining and hydrogenation of
vegetable oils, plastic compositions and rein-
forced metals are of recognized industrial im-
portance.
In addition to 190 educational, scientific and
technologie papers, Charles Baskerville was the
author of the following books: “School Chem-
istry,’ 1898; “Key to School Chemistry,”
1898; “Radium and Its Applications in Medi-
cine,” 1906; “General Inorganic Chemistry,”
1909; “Laboratory Exercises” (with R. W.
Curtis), 1909; “Progressive Problems in Chem-
istry” (with W. L. Estabrooke), 1910; “Quali-
694
tative Analysis” (with L. J. Curtman), 1910;
“Municipal Chemistry” (with other experts),
1911; and “Anesthesia” (with J. T. Gwath-
mey), 1914.
Charles Baskerville became a member of the
American Chemical Society in 1894 and later,
as councilor and chairman of important com-
mittees, rendered much valuable service. His
activities on the society’s committee on occu-
pational diseases in the chemical industries
were especially prominent. He was one of the
most constant attendants upon the annual
meetings, effectively laboring for the best inter-
ests of the society. He was also a fellow of

Charles Baskerville’s great forte was in
making practical suggestions for the better
conduct of affairs. At North Carolina and
later at the College of the City of New York,
he was respected as an able teacher who kept
in close and sympathetie touch with his stu-
dents; but he did not confine himself to the
teaching side of education. Upon the comple-
tion of the chemical laboratory of the College
of the City of New York, which he designed,
he took rank among the foremost laboratory
directors of the United States. He was indeed
an organizer and administrator of the highest
order. Indomitably energetic in his executive
duties, and aided by an active staff of carefully
selected chemical specialists, he succeeded in
establishing and operating a strong department,
and in consequence his influence extended
throughout the institution. Constantly alert to
help and keenly interested in bettering condi-
tions, his accomplishments for his associates
were numerous. His most attractive personal
characteristics led to friendships of weight,
which, in turn, benefited his colleagues and
students.
An intellect more powerful from its happy
union of scientific ability with broad culture
has probably not been seen in the American
chemical profession. He was inferior to none
in extent of literary acquirement, in penetra-
SCIENCE
[Von. LV, No. 1435
ting and fertile executive ingenuity, and in
general equipoise of mind. And withal he
tried to be his “own man,” generous, kindly
and sympathetic. The spirit of goodness is
ever the same; but the modes of its manifesta-
tion are numberless, and every sterling man is
original. The vigor and sincerity of this
sterling man made his friendship a treasure.

SCIENTIFIC EVENTS
THE PENSION AND INSURANCE PLAN OF
PRINCETON UNIVERSITY
A PENSION and insurance plan for the Prinee-
ton University teaching staff was adopted on
June 19 by the board of trustees at their an-
nual meeting, held in connection with the uni-
versity’s one hundred and seventy-fifth com-
mencement exercises. It provides for the
raising of a special fund of $1,000,000 not later
than 1925, to provide the money that will be
required under the trustees’ action.
The plan, which was placed before the trus-
tees by a special pension committee of which
John O. H. Pittney is chairman, supplements
the provisions of the Carnegie Foundation, of
which about 90 per cent. of the faculty are at
present beneficiaries.
Any member of the university teaching staff
may, under the plan approved, retire at
the age of 65, and every member must retire at
68, provided, however, that in special cases by
a vote of the board of trustees an individual
may be continued in active service beyond the
retiring age period not exceeding three years.
The general provisions of the plan are as
follows:
Every member so retiring shall be entitled to
receive during the remainder of his life an annual
retiring allowance equal to one half of his annual
salary as teacher at retirement:
Provided that the obligation of the university
shall be reduced by the amount of any Carnegie
or similar allowance to which any such member
may be entitled. Any member so retiring, not
immediately entitled to a Carnegie allowance,
shall receive from the university his half salary
as before defined (with such additions thereto as
may be necessary to qualify him for the maximum
Carnegie allowance) until he is entitled to maxi-
mum allowance under the Carnegie rules. Any
JUNE 30, 1922]
member of the teaching staff who is entitled to a
Carnegie retiring allowance and who forfeits such
retiring allowance because of any voluntary act by
which the same is forfeited under the Carnegie
rules, may be deprived of his retiring allowance
from the university.
The university will provide life insurance that
shall assure to each member of the teaching staff
the payment of $5,000 on his death before his
retirement, payable to his wife if he leaves one,
otherwise to his children, or, if he leaves none,
then to such person as he may, with the approval
of the president, designate.
“An alternative” plan” submitted by the com-
mittee on pensions and also approved covers
the cases of members of the faculty who hold
deferred annuity policies issued by the Teach-
ers’ Insurance and Annuity Association of
America or other companies approved by the
university finance committee. The university
will, on the request of a member of the faculty
and his relinquishment of all benefits under
the insurance and pension plan, contribute to-
ward the payment of the premiums on such
annuity policies a sum not exceeding five per
cent. of his annual salary, nor a maximum of
$300.
GIFTS TO THE AMERICAN MUSEUM OF
NATURAL HISTORY
Girts of $1,000,000 by Mr. John D. Rocke-
feller, Jr., and $250,000 by Mr. George F.
Baker to the American Museum of Natural
History were announced by President Henry
Fairfield Osborn at a meeting of the executive
committee of the board of trustees last week,
when the following resolutions were passed:
Resolved, That the trustees accept with grateful
thanks the splendid gift of $1,000,000 presented
to the museum by Mr. John D. Rockefeller, Jr.,
for its corporate purposes and hereby take
pleasure in applying it to the permanent endow-
ment fund, the principal to be kept invested and
the income only to be expended for the work of
the institution.
This munificent gift, valued at more than a
million dollars, is the more appreciated because it
is received at a time when the increase of the
permanent endowment by at least $2,000,000
stands as the paramount need of the museum, in
order that its scientific exploration and research
may not be curtailed and in order that it may
continue to render to public education, especially
SCIENCE
695
through the school system of the city and country,
a service which is increasing in importance and
is receiving universal approval of educators.
Mr. Rockefeller’s attitude in his generous terms
of gift and in his liberal-mindedness with respect
to the use of this fund is a further source of deep
satisfaction and encouragement to the trustees be-
cause it indicates his hearty endorsement of the
aims and purposes of the museum and of the trus-
tees’ policy in its development and expresses his
belief in the present and future service which it
can render to science and education for all the
people.
In recognition of Mr. Rockefeller’s interest in
the museum, the trustees take pleasure in hereby
electing him a benefactor.
Resolved, That the trustees desire to record
their deep sense of gratitude to Mr. Baker for
his generous gift of $250,000, which constitutes
the initial contribution to the much needed en-
larged endowment for the growth and develop-
ment of the museum. The trustees deeply appre-
ciate not only the intrinsic value of the gift, but
especially the generous attitude of the donor in
permitting the unrestricted use of the income of
this fund—an action which is indicative of his
confidence in the administration of the museum
and the aims and purposes of the institution. In
recognition of Mr. Baker’s earlier contributions,
the trustees had previously elected him a_bene-
factor, and can therefore merely express their
gratitude to him by extending their heartfelt
thanks and best wishes for continued good health
and happiness.

[Vou. LV, No. 1435
for the degrees Professor William Lyon Phelps
spoke as follows:
JOHN CAMPBELL MeERRIAM: President of the
Carnegie Jnstitution, paleontologist and educator.
Born in Iowa, where he took his first degree at
Lenox College in 1887. Doctor of philosophy of
the University of Munich. He began his profes-
sional career as an instructor in paleontology and
historical geology at the University of California
in 1894, and since that date he has become a
leading authority in fossil reptiles and fossil
mammals of western North America, and of gen-
eral historical geology of the Pacific coast region.
He is a member of many learned societies and his
publications are numerous and important. He
was for years professor of geology and dean of
the faculties at the University of California. He
was largely instrumental in establishing the
Pacific exploration project which has taken on
large dimensions, involved wide ranges of science
and large numbers of scientists. During the late
stages of the war, he acted as chairman of the
National Research Council. He is a member of
the National Academy of Sciences and widely
tegarded by scientific men as one of the half
dozen conspicuous representatives of American
He combines to an extraordinary degree
ability as an investigator with ability as a teacher.
JOHN JOSEPH Carty: Vice-president of the
American Telephone and Telegraph Company,
A pioneer in the development of telephone science
since 1879. He designed and constructed the first
metallic cireuit multiple telephone switchboard.
A high authority states that his original re-
searches published in 1889 demonstrate the pre-
ponderating effect of electrostaic induction in
producing cross-talk on adjacent telephone cir-
cuits. Cross-talk is presumably used only in a
technical sense. He invented the method of com-
mon battery work now in general use throughout
the world. The bridging telephone was designed
by him; this forms the basis of all farmers’ party-
lines, thus adding social knowledge and delight
to the existence of wives. He is a
leader in the movement to encourage research in
pure science at the universities. During the war
he was chairman of the executive board of the
National Research Council. He rendered invalu-
able service in preventing the interruption by the
enemy of our trans-Atlantic cable communications.
He designed the telephone and telegraph system
for the American Army in France. He served as
colonel in the United States Army as a staff offi-
cer, and is now brigadier-general of the Officers’
Reserve Corps. For his services in establishing
farmers’
JUNE 30, 1922]
the telephone system in Japan, he received there
the Order of the Rising Sun and of the Sacred
Treasure. For his war services, he was given the
formal thanks of the French Army, the cross of
Officer of the Legion of Honor and the Distin-
guished Service Medal from the United States
government.
RusseLL Henry CHITTENDEN: Dr. Chittenden
was born in New Haven, and his active career has
been identified with the Sheffield Scientific School,
a fortunate thing for that institution. He took
his bachelor of philosophy degree there in 1875.
After taking his doctorate in the Graduate School,
he studied at Heidelberg, and has received hon-
orary degrees from the University of Toronto,
University of Pennsylvania, Washington Univer-
sity, and the University of Birmingham in Eng-
land. His researches and publications in the field
of physiological chemistry have made him one of
the world’s foremost authorities; and during the
war he represented America on the Inter-Allied
Scientific Food Commission, which held sessions
in London, Paris and Rome. In 1898 he was
appointed director of the Sheffield Scientific
School, where he immediately showed executive
ability as remarkable as his powers of research.
Under his leadership the Sheffield Scientific
School became a liberal college, one of the best
in America, where the study of the humanities
had no stronger friend than the great scientist
who directed the institution. Its growth in num-
bers and in buildings and in resources was phe-
nomenal; leading authorities were numerous on
the faculty, Dr. Chittenden’s devotion to the
avocation of fishing enabling him to be a good
fisher of men. He retires from office this year
in the plenitude ot his powers, with the respect
of the best scholars in Europe and America, with
the admiration of his colleagues, and with the
- devoted affection of thousands of students who
have been graduated under his administration.

A REFLECTING telescope with a 61-inch mir-
ror is to be made for Ohio Wesleyan University.
It will be housed in the Perkins Observatory,
of which Professor Clifford Crump is director.
There are only two reflecting telescopes in the
world which will exceed this new instrument
in size, according to officials of the Warner
and Swasey Company, which has contracted
to make the installation. These are the 100-
700
inch reflector at the Mount Wilson Observatory
in California and the 72-inch one at Victoria,
British Columbia. The $250,000 for its con-
struction was given by Professor M. H. Per-
kins, for twenty-five years an instructor in
mathematics at Ohio Wesleyan, who has made
many other contributions for the upkeep and
maintenance of the observatory. A feature of
the telescope is that it will be devoted pri-
marily for the use of the students in the uni-
versity and only secondarily for research. This
is the first of the large instruments to be so
used. Three years will be required to complete
the installation.
A Bera Cuaprer of Sigma Delta Epsilon, a

THE Biological Station of the University of
North Dakota at Devil’s Lake is planning to
‘continue this season the work which it has been
conducting for a number of years past, which
includes experiments on the influence of solu-
tions of different salts of varying concentra-
tions upon fishes, in the attempt to ascertain
SCIENCE
[Vou. LV, No. 1435
the cause of death of fish in such solutions. It
is also continuing the biological survey of the
state, upon which considerable progress has
already been made. The work this year will be
centered, chiefly on the fishes, reptiles and
Amphibia. Reports have already been pub-
lished, or are in press, dealing with a number
of groups, including the birds, mollusks, Pro-
tozoa, locusts, and bugs (Hemiptera). This
latter work is in charge of Miss Crystal Thomp-
son, of the Amherst College Museum, and is in
cooperation with the Museum of Zoology at
Ann Arbor. The environment of Devil’s Lake,
with numerous ponds differing markedly in
their physical and chemical characteristics,
marshes, woodland, and cultivated land, con-
tains a rich fauna for ecological studies, espe-
cially on aquatic life.
WE learn from Nature that the Strangers’
Hall, Norwich, an old city merchant’s house,
with groined undereroft, fifteenth century ban-
queting hall, and other paneled rooms of later
date, has been offered by its owner, Mr. Leon-
ard G. Bolingbroke, to the corporation of Nor-
wich for the purpose of an English Folk and
Historical Museum, in conjunction with the
Norwich Castle Museum. Mr. Bolingbroke has
also offered his collection of old domestic appli-
ances and other “bygones” illustrative of the
various phases of a middle-class Englishman’s
home during the last four or five centuries,
which will find a fitting environment in the
various rooms of the house. While the aim of
the museum will be historical rather than scien-
tific, there will be found many exhibits of
interest to students of early history and devel-
opment of such subjects as the production of
light and fire, domestic cookery, and other
kindred objects.
THE Royal Geographical Journal reports
that an expedition lately left Copenhagen for
the Dutch East Indies with the object of taking
preliminary steps towards the establishment of
a Tropical Station for Biological Research
in that region. It is headed by Dr. T. Morten-
sen, of the Copenhagen Zoological Museum,
and the botanist is Hjalmar Jensen. The pro-
ject was set on foot some years ago and has
been brought to a head through the labors of
a Scandinavian Society formed for the pur-
JUNE 30, 1922]
pose. The present expedition has been ren-
dered possible by a grant from the “Rask-
orsted Fund.” The probable site of the station
will be in the Ké islands, previous research
having shown that there is an unusual abun-
dance of animal life in the waters to the west
of the group. What is really a deep-water
fauna is here found at comparatively small
depths—200-300 meters—making it easy to col-
lect rare deep-water species. It is possible
that Dutch cooperation may be secured, and
in any ease the intention is to give an inter-
national character to the station.

DISCUSSION AND CORRESPOND-
ENCE
THE NEW CATASTROPHISM AND ITS
DEFENDER
REFERENCE was made in my contribution to
Science for February 17 to Professor Price,
alleged geologist, upon whose scientific vagaries
a reactionary theology relies much in its recent
attack on evolution—the result of a reeru-
descence of the old conflict which such a the-
ology has ever waged against the progress of
selence.
George McCready Price, who since 1906 has
held positions as professor of geology, College
of Medical Evangelists, Loma Linda, Califor-
nia, professor of English literature, Fernanda
Academy, California, and professor of chem-
istry and physics, Lodi Academy, California,
is evidently in the religious denomination
(Seventh Day Adventist) to which he belongs
held to be a man of considerable versatility.
The writings by which he is best known are
two books, “Fundamentals of Geology” (1913),
and “Q. H. D., or New Lights on the Doctrine
of Creation” (1917), and numerous articles in
the religious press—chiefly the Philadelphia
Sunday School Times.
The distinctive ideas for which he stands in
702
geology (the only ones to be reviewed in this
article) are:
First: What he terms the “New Catastro-
phism,” which turns out to be nothing more
than the Old Catastrophism embodied in the
Noachian Deluge.
Second: A literal creation of material things
(the sidereal universe with its parts appar-
ently in different stages of development—its
nebule, hydrogen stars, metallic stars, carbon
stars and dark stars); and all animate things
(trilobites, nummulites, graptolites, ammonites,
sigillaria, the fishes of the Old Red Sandstone,
the large reptiles of the Mesozoic, the mam-
moth and the mastodon, the one-toed horse and
the three-toed horse, and man) all at one and
the same time just as set forth in the first
chapter of Genesis.
While not committing himself to any esti-
mate of the time back of the present when all
this took place, it is evident that he leans to a
“short chronology’; for in Chapter IX of his
Fundamentals of Geology he argues for a
catastrophic instead of a uniformitarian rate
for the deposition of strata. In Chapter I of
his “Q. E. D.” he refers to the study of the
phenomena of radioactivity as having “thrown
a good deal of doubt upon the older estimates
of the age of the earth,’ but he fails to inform
his reader that such study has revealed the
necessity of postulating a long succession of
atomic transformations, and has enormously
extended the length of geologic time.
Realizing that if there has been a geological
succession of life on the earth
“‘then some form of genetic connection between
these successive types is the intuitive conclusion
of every thinking mind, even though the recovery
of these connecting links may prove impossible,’’
and his Genesis account, which he is out to
defend at all hazards, goes by the board, he
flatly denies that there has been any geological
succession, and sets himself to the task of en-
deavoring to prove the astounding thesis “that
all fossils are of the same age and none of
them older than man.” In doing this he shows
wide familiarity with geological literature,
quoting largely from the most eminent authori-
ties in this country and in Europe. Any one
reading these writings of Price, which possess
a certain charm of literary style, and indicate
on the part of the author a gift of popular

presentation which makes one regret that it
had not been devoted to more laudable purpose,
must constantly marvel at the character of
mind of the man who can so go into the litera-
ture of the subject and still continue to hold
such preposterous opinions.
The position of superiority he arrogates to
himself is amazing: With his solicitude for har-
monizing his views with those of the Bible so
palpable, one of his eyes, at least, being always
“kept on Genesis,’ he still has the face to
accuse all “other geologists” of being biased,
charging that they hold to a belief in geological
succession “solely on the strength of the infalli-
bility of a theory” (elsewhere referred to as
the onion-coat theory of Werner) “invented a
hundred years ago in a little corner of western
Europe.”
So much under the spell of this old Wer-
nerian hypothesis are geologists still (excepting
himself), that, according to Price they “invent”
unconformities and faults to explain breaks
and repetitions in the life succession.
Price especially endeavors to find “mare’s
nests” in the “alleged” great thrust faults of
the earth, impugning the competency or integ-
rity, or both, of the distinguished geologists
who vouch for their existence: as that of Heim
and Rothpletz for the great Glarus overthrust
in the Alps, that of Geikie for the great over-
thrust in Scotland, that of McConnell, Camp-
bell and Willis for the great overthrust along
the eastern front of the Rockies in Canada and
northwestern United States, and finally that of
Hayes for the numerous overthrusts in the
southern Appalachians.
Professor Price also thinks he has found an-
other geological “mare’s nest,” one that ought
to confound these believers in a geological sue-
cession, in the fact:
‘«That the rivers of the world in cutting across
the country, completely ignore the varying ages
of the rocks in the different parts of their courses,
and act precisely as if they began sawing at them
all at the same time.’’
Evidently the conception of a superimposed
river, disclosing old buried structures as it
deepens its channel, so easily understood by any
high school student of physiography, is beyond
the mental grasp of the author of “Funda-
mentals of Geology.”
This then is the man who, while a member
JUNE 30, 1922]
of no scientific body and absolutely unknown
in scientific circles, has in at least one of his
contributions to the religious press (the one in
which he tried to make much of the so-called
anti-evolution admissions of Bateson) had the
effrontery to style himself “geologist,” in the
expression he there used “we geologists’; and
this is the man who in his support of a literal
Genesis is hailed by the “Fundamentalists” as
their great champion—one who has “demon-
strated the absurdity of the evolutionist’s
geological theories” and has brought into prom-
inence the “heretofore mute evidence of a
mighty upheaval and a flood.”

KEYS IN SYSTEMATIC WORK
To tHe Hprror or Science: It seems more
mechanical uniformity is possible in the keys
which systematists find of so much value in
descriptive work. The number of forms used
now is limited apparently only by the num-
ber of authors publishing such keys, and among
this large number of forms are many which
are wasteful of space and many which are
confusing to the student.
Some of the mechanical requirements of a
good key may be briefly summarized:
1. The key should oceupy a minimum
amount of space, and should present the mini-
mum difficulty to the printer.
2. The key should be capable of indefinite
expansion, that is, provide for any number of
groups, and no headings of groups or sections
should be duplicated.
3. Any desired space under each heading
should be available.
4. Coordinate groups in the key should be
recognizable as such at a glance and such co-
ordinate groups should be in juxtaposition.
5. The key should be as readily “run back-
ward” as “run forward.”
Ample reasons for all these requirements
could be given but need not be detailed here.
The following skeleton key shows a form which
I believe meets all these requirements, and it
is presented for criticism in the hope that after
discussion some form of key may be found
which will meet with general approval. Sec-

THE Y-CHROMOSOME TYPE OF _ SEX-
LINKED INHERITANCE IN MAN
In a short article which appeared in the
Journal of Heredity for November, 1921,
Richard Schofield describes a case of human
inheritance whieh has very great theoretical
interest. It involves the transmission through
four generations of a condition called webbed
toes. The condition is found only in male
members of the family and is transmitted from
father to son, never to a daughter nor through
a daughter to her sons.
It thus has the distribution in heredity of a
Y-chromosome, a structure found only in the
male-determining spermatozoa of certain ani-
mals and never in their eggs. The Y-chromo-
some accordingly is a structure possessed by
male individuals only and thus forms an ap-
propriate vehicle for the transmission of char-
acters from father to son, quite independently
of the female line of descent. All this was
pointed out by Schmidt in a contribution from
the Carlsberg Laboratory, which I reviewed in
Science for April 8, 1921, under the title
“A New Type of Inheritance.” Schmidt
deseribed in a fish the first known case of
inheritance of this type. This has since been
confirmed in the case of another species of fish
by a Japanese observer, so that it may now be
regarded as well established. Schofield’s article
704
furnishes evidence that the Y-chromosome type
of inheritance occurs in man as well as in
fishes.

THE VOCABULARY OF METABOLISM
I wish to suggest in the columns of SclENCE
the following new terms in the vocabulary of
metabolism: (1) Eubolism, a condition of
normal bodily metabolism; (2) Pathobolism, a
condition of perverted metabolism of a diseased
nature, as, for example, diabetes; (3) Dysbol-
ism, a condition of disturbed metabolism not
necessarily of a diseased nature, as, for ex-
ample, alkaptonuria. I believe that these terms
will supply a want in the terminology of meta-
bolism.

SALARIES OF PROFESSORS IN POLAND
I rake the following item from the weekly
news release of June 7 of the Polish Bureau of
Information:
Because of the importance attached to their
role in the life of the nation, the university pro-
fessors of Poland have been granted salaries
greater than those to which their official rank
would entitle them. [The official rank of full
professors in Polish considered
equivalent to that of major generals. |
If they have been in service fifteen years and
are supporting families, they are to receive
monthly salaries of 139,000 marks. This approxi-
mates the salaries of cabinet ministers, who re-
ceive about 160,000 marks monthly, and is slightly
in excess of those of vice-ministers, who receive,
including representation funds, about 137,000
marks.
These salaries for professors have been made
possible by a special provision in the state budget,
appropriating 357,906,966 marks for professors’
salaries and 87,625,761 marks for the salaries of
assistants, a total of nearly half a billion marks.

SPECIAL ARTICLES
THE SPIRAL TREND OF INTESTINAL
MUSCLE FIBERS
In the Anatomical Record for May, 1921
(Vol. 21, pp. 189-215), Professor Carey pub-
lished his “Studies on the Structure and Fune-
tion of the Small Intestine.” These were re-
printed, in part, with the title, “Studies on the
Anatomy and Muscular Action of the Small
Intestine,’ as the opening article of volume 1
of the Journal of Gastro-Enterology (July,
1921). ‘The first conclusion, and the only one
on which comment is here to be made, is this:
The inner muscle coat of the small intestine is
not composed of circular or annular rings contigu-
ously placed, but is a continuous muscular sheet
wound into a close helix. One complete turn is
made in every 0.5 to 1 mm. or less (Anat. Rec.,
p. 193; Journ. Gastro-Ent., p. 9).
Professor Carey characterizes the conception
that the inner muscular coat is composed of
discrete muscular rings with a certain degree
of connection, as “a faulty anatomical heir-
loom’’—an “erroneous idea which arose with
the inception of the microscope and has since
been accepted unchallenged.” There is, how-
ever, a neglected anatomical heirloom, with
which perhaps the author was unfamiliar, in
the form of “A Discourse concerning the
Spiral, instead of the supposed Annular, struc-
ture of the Fibres of the Intestins; discover’d
and shewn by the Learn’d and Inquisitive Dr.
William Cole to the Royal Society” (Phil.
Trans., 1676, Vol. xi, pp. 603-609). This dis-
course, not now readily accessible, is so admir-
ably confirmed by Professor Carey’s repetition
of the work as to repay examination.
At the time of Dr. Cole’s studies, Willis, in
his Pharmaceutice rationalis, published two
years previously, had described the interior
fibers of the muscular coat as “annular, every-
where girdling in close-set ranks the cavity of
the intestines, and inserted into the edge of the
mesentery as in a tendon.” Overlying these,
and “crossing them at right angles,” he found
straight or longitudinal fibers, and believed
that the sinewy outer layer wrapped around
them served them in place of tendons. (Earnest
efforts were made by the early anatomists to
JunE 30, 1922]
find tendons for smooth muscle!) From the
mesentery and from the fibers of the outer
coat, the cireular and longitudinal muscles,
respectively, received the animal spirits or
nervous energy whereby they were at first
inflated and distended, thereafter becoming
shorter and more contracted. As to the action
of the two sets of muscle fibers, he wrote:
Indeed the circular fibers, having contracted
successively and seriatim, constrict the diameter
of the intestine; and at the same time the longi-
tudinals, inflated and distended, narrow it still
more and produce a downward movement, so that
the contents of the intestines, thus compressed
from behind, must constantly be driven forward.
With such a description current, Dr. Cole
begins his paper as follows:
Discoursing (near two years since) with a very
ingenious Person, concerning the Mechanical rea-
son of the Peristaltick motion of the Intestines,
which is by Anatomists deduced principally from
Annular fibres, constituting, according to the re-
ceived doctrine (with the right fibres immediately
investing them, though, by the by; I take these
to make a distinct coat) one of the coats of them;
his sence was (which he told me was that likewise
of some others of his acquaintance) that they
might be rather numerous, though small, Sphine-
ter-muscles, than single fibres, to which that mo-
tion is to be attributed.
For four theoretical considerations Dr. Cole
dissented, namely (1) that on the supposition
of circular sphineters there would be no con-
tinuous lengthwise channel for the propaga-
tion of motion, and (2) lateral transmission
seems not to be agreeable to nature’s methods.
Moreover, (3) lateral exits would tend to pre-
vent distension of the fibers by the influent
matter; and (4) circular muscles lack two ten-
dons by the approximation of which all mus-
cular work is accomplished. He therefore
offered the following solution:
Viz. That those fibres which have been esteemed
annular, might perhaps be spiral, and so be con-
tinued down in one tract to the lowest extremity
of the intestines; . . . their declination being not
easily discernible... But ... I consider’d ’twas
too unphilosophical to acquiesce in bare specula-
tion, when autopsy might be consulted; and there-
fore I set upon the experiment, first in the upper
intestines of an Ox, afterwards in those of Sheep
and Calves... .
SCIENCE
705
To effect a due disjunction of the membranes
and fibres (which I found ’twas hard, if not
impossible, for me to make while ’twas raw), I
was fain to cause the intestine of Oxen to be
boiled 5 or 6 hours, of Sheep 4; whereby the com-
pages of the parts was so loosned, that the two
outward coats were easily separated from that to
which my search was destined, and left those
reputed annular fibres naked.
The results of attempting to follow, through
separation, the course of the bundles of these
muscle fibers—single fibers being found too
small to isolate—Dr. Cole records in numbered
paragraphs, from first through “eighthly.”
The following are selected statements, abbre-
viated (as were previous citations) :
When, beginning at the top, I attempted the
separation of one of these clusters of fibres
towards my right hand (on that side of the intes-
tine, I mean, which was turned towards me) a
whole ring would come off together ...; but
endeavouring it towards my left, I found, for the
most part, I could easily enough unravel that
cluster to a considerable length, viz., that of some-
times more than two or three spans, before rup-
tion, which yet at last ’twould be subject to.
If I began at the lower part of the intestine,
and try’d to unravel upwards, there was not much
more difficulty in so doing . . . [But] the opera-
tion, I observ’d would not succeed, unless I at-
tempted it on the contrary order, viz., towards
my right hand.
When before boiling I caused the inside of the
intestines to be turned outward, as I did in two
tryals,...and endeavoured to unravel the
fibres, I found they would come off in the con-
trary order ... the intestine being inverted, the
order of separation must be so too.
Other observations are that the obliquity of
the spiral may vary; that the spiral is less
well-defined in the cecum; and that everywhere
some fibers deviate from the main trend, being
in the opposite order, or forming intercom-
munications between the turns of the spiral.
But the general conclusion reached is that the
fibers altogether form “one concave helical
muscle.”
Where the tendons of it are fixed is not evident;
but if I may have the liberty of conjecture, I
should think the upper of them to be radicated
at the pylorus (if not as high as the sphincter,
gule); and the other at the anus.
Whether the supposed annual fibres of the veins
706
and arteries may not have the same fabrick as
those of the Intestines . . . I propose to be con-
sidered and examined by persons of more acute
hands and judgment; as I do all what I have
here delivered, nor daring too much to trust even
the informations of my own hands and eyes, till
I find them confirmed by those of others, more
judicious as well as more dextrous in making ex-
periments.
After two centuries Professor Carey has sup-
plied the needed confirmation except im one
particular; he finds that the spiral winds in
the opposite direction! Carey describes a
“left-handed helix,’—a spiral which reverses
the direction of the rotation of the embryonic
stomach and goes counter to the twisting of
the cwsophagus. But Dr. Cole recorded the
type familiar in dextral gastropod shells, which
aceords with the rotation of the stomach.
Although it often happens in nature, as noted
by Thompson, that two opposite systems of
geodetic spirals exist together, and interfere
with one another, forming a criss-cross pat-
tern! (and indeed such a condition has been
recorded for the w@sophageaf muscles of rum-
inants?), it can not be invoked to reconcile the
conflicting statements regarding the direction
of the intestinal spiral, since both Cole and
Carey agree that there is but one well-defined
cleavage. Under these circumstances, the ques-
tion has been referred to Professor Sykes, who,
during the past season, while studying in the
Harvard Laboratory, has frequently unwound
the circular muscle of the intestine. Although
his results are to be published elsewhere, I am
permitted to report that he has verified the
early work of Dr. Cole in regard to the direc-
tion assumed by the spiral; it is dextral. If
this is so, Dr. Carey’s explanation of that pri-
mary torsion of the embryonic intestine which
determines the disposition of small and large
bowels in the adult, though very ingenious, must
be considered illusory, for it depends on sinis-
tral coiling and tension.®
The origin of the spiral trend of the muscles
is ascribed by Dr. Carey to “the rotating spiral

NEARCTIC PROTURANS
THe Protura—the most primitive of all the
insects, if indeed they are insects—were first
reported from the Nearctie Region in 1909. In
that year the eminent Italian zoologist and
entomologist, F. Silvestri, collected and de-
seribed under the name of Hosentomon wheeleri,
a single species from New York. For the
next twelve years no record was added from
the vast area of the Nearctic.
The second record from this region was ob-
tained in 1921 from the vicinity of Washing-
ton, D. C., the first specimen being found by
H. S. Barber, who accidentally came across it
in some leaf mold in which he was rearing
beetle larve. Other specimens of the same
species, which proved to be new, were soon
taken, and the species described by the writer
as Acerentulus barberi.
Following the initial discovery at Wash-
ington the writer has been fortunate enough to
encounter Proturans in large numbers and in
considerable diversity at Takoma Park, Mary-
land. Here during the spring of 1921 no less
than twelve species, representing six genera,
were found, ten of them proving to be new.
These have been described in a paper presented
at a meeting of the Entomological Society of
Washington.?
To these records obtained in the vicinity of
Washington are now added several more from
widely separated localities, and in some
instances from different life zones of the
Nearctie Region. These localities are as fol-
lows: Chesapeake Beach, Md.; top of Blue
Ridge Mountains, near Bluemont, Va. (eleva-
tion 1,200 feet); near Prospect Hill, Va.;

In addition, also, Professor Silvestri has

It would be premature at this time to attempt

these records coming from 4 different states;
from 2 localities in the Lower Austral Life

STEM END ROT OF APPLES
During the late spring of 1921 a large
number of apples were found which developed
a decay at and around the base of the stems.
These apples were in a lot that had been re-
moved from a cold storage, temperature of 32°
and held for a few days at 45° Fahr. When
placed in moist chambers such apples very
soon decayed without wrinkling, becoming soft
and watery. The decay was of a sharply de-
fined nature, such that the affected parts could
be easily removed. Normally these decayed
apples were soon covered with green mold. On
examining the stems of apples in storage it
was found that many stems were green with
spores. Cultures of this mold were made by
the poured plate method. The fungus was be-
lieved to be Penicillium expansum Link., and
was later identified as such by Mr. Charles
Thom of the U. 8. D. A., Bureau of Chemistry.
A search of the literature on apple decay
was made, but no mention of the entrance of a
decay-producing organism through the stem
was noted. The decay of apples ordinarily
caused by P. expansum is invariably mentioned
in connection with abrasions of the skin, such
as insect punctures, wounds or injuries of a
mechanical nature. Some writers mentioned
the infection as entering through the calyx or
blossom end but no one noted stem end infec-
tion.
The matter was taken up with Mr. H. A.
Siegler, assistant pathologist of the U. S. D. A.,
Bureau of Plant Industry; Mr. Charles Brooks,
pathologist, and Dr. Charles Thom, mycologist,
U. 8. D. A., Bureau of Chemistry, none of
whom had noted such a decay gaining access
to the apple by way of the stem. In fact they
708
doubted the possibility of any fungus travers-
ing the dry stem of an apple. It is well proven
that stem end rots oceur in other fruits, for
example, the stem-end rot of citrus caused by
Phomopsis sp. and the stem-end rot of both
citrus and watermelon caused by two species
of Diplodia.
In the fall of 1921, large, mature Yellow
Bellefleur apples were secured from trees in a
Berkeley garden. These apples were picked
with the fruit spurs attached, carefully washed
in wood alcohol, mercuric chloride solution
1-1000 and distilled water consecutively. The
leaves were clipped from the spurs to facilitate
the work but the spurs were not removed.
Moist chambers were sterilized, lined with filter
paper, washed out with mercuric chloride solu-
tion, rinsed with distilled water, glass covers
were prepared in the same manner. The spurs
were then removed from each apple in turn
and spores of P. expansum from sub-cultures
made from the original isolation were planted
on the freshly exposed surface at the ends of
the apple stems, and the apples placed in the
moist chambers. Control apples similarly
treated but not inoculated were placed in jars
prepared in the same manner and all were
kept under the same conditions in the labora-
tory. Of the six apples treated in this manner,
four developed the characteristic stem end rot
and were soon completely decayed. The check
apples kept in good condition for three months.
Yellow Newtown apples were picked in the
same manner at Watsonville, California, and
brought to Berkeley. On October 17, 1921,
three of the ripest of these apples were treated
and inoculated in the same manner as the
Bellefleurs. On November 18 the decay of all
three apples was identical with the decay ob-
served on the fruits naturally infected. Six
Yellow Newtown apples were treated in the
same manner and inoculated with the same
organism several days later than the previous
group and they all developed the typical decay.
In all eases the checks remained in good con-
dition. At the end of six weeks, all the apples
so inoculated were entirely decayed and covered’
with green spores.
Cultures of the spores appearing on the sur-
face of the inoculated apples were made and

appeared identical in every way with the
original culture. Stab inoculations were made
with these re-isolated cultures on apples also
carefully sterilized. At the same time other
apples were inoculated with the original cul-
ture. The results were identical, the typical
Penicillium decay of apples resulting at every
puncture. A penicillium isolated during the
fall of 1921 from decaying prunes was found
to cause typical decay of apples when inocu-
lated into the flesh. This prune penicillium
was planted on three Yellow Newtown apple
stems and within three weeks it caused typical
stem end decay of all three apples. This organ-
ism was later found to be identical in all of its
reactions with the original penicillium isolated
from apples.
Washings made from the attached leaves on
some of the apples used in the experiments
were plated and typical colonies of P. expan-
sum appeared on all the plates so made. About
15 per cent. of the colonies which grew were
identified as some species of Penicillium, a con-
siderable number of which caused typical P.
expansum decay when inoculated into mature
apples. This would indicate the prevalence of
the organism in the trees at the time of harvest.
These results prove that stem end infection
of apples is a possibility. Observations by
the writer indicate that this mode of infection
is quite common among the apples of this state,
especially in Yellow Newtowns. Though re-
tarded in cold storage, the rot makes some
progress at a temperature of 45° Fahr. and at
room temperature the decay is rapid.

UNIVERSITY OF CALIFORNIA,
AMERICAN PHYSIOLOGICAL
SOCIETY
’ THIRTY-FOURTH ANNUAL MEETING
Tue thirty-fourth annual meeting of the
American Physiological Society was held during
the Christmas holidays under the patronage of
Yale University, New Haven, Connecticut. Two
scientific sessions daily were held December 28,
29 and 30. The meetings opened at 9:30, De-
cember 28, with a joint session of the societies
of the Federation of American Societies for
Junez 30, 1922]
Experimental Biology, under the chairmanship
of J. J. R. Macleod of the physiologists. A
vigorous program of reports on the scientific
subjects announced below was carried out in
the six half-day sessions.
The afternoon of December 29 a joint dem-
onstration was held in the halls of the Osborne
Zoological Laboratory. The demonstrations of
the American Association of Anatomists oc-
curred at the same time. This brought the two
great groups of scientists of the pre-medical
sciences together in what proved to be a very
pleasing and outstanding demonstration of
scientific progress for the year.
Three business sessions were carried forward
at which the more important steps and deci-
sions made were as follows:
1. The report of the treasurer, Dr. Joseph
Erlanger, of Washington University School of
Medicine, showed a net balance of $467.07.
2. The. annual assessment was placed at one
dollar per member.
3. An appropriation of $125 was made in
aid of the English journal, Physiological Ab-
stracts.
4, The council announced the appointment of
J. Hepburn of the University of Toronto to
the fellowship established at the last annual
meeting under the grant of Dr. W. T. Porter.
Dr. Hepburn is pursuing his research in the
subject of ‘The Reactions of the Respiration
Center to Lack of Oxygen.” This investigation
is being carried out in the Laboratory of
Physiology, University of Toronto, under the
direction of Professor J. J. R. Macleod.
5. The society voted approval of the prin-
ciples stated in the Cannon-Henderson resolu-
tion, instructing its officers of the executive
committee of the federaiton to support the
same.
6. The council announced the appointment of
Donald R. Hooker of Baltimore as managing
editor of the American Journal of Physiology
for the year 1922.
7. The council recommended and the society
voted the following changes in the rules gov-
erning the publication of Physiological Re-
views. These changes affect the general man-
agement of the journal by reserving to the
SCIENCE
709
council the appointment of the chairman of the
editorial board, and by transferring the ap-
pointment of the managing editor to the edi-
torial board.
8. The report of the managing editor of the
American Journal of Physiology to the council
which was transmitted to the society showed a
progressive recovery from the war time deficit
in the issue of the successive volumes of the
journal. At the present time the cost of pub-
lication per volume is only slightly greater
than the income for the same. The net balance
in the journal fund is $9,659.62.
The council announced that in order to over-
come the delay in publication a free volume of
the journal would be issued immediately, and
beginning with the next current volume the size
of the journal would be restored to the stand-
ard of 600 pages.
9. The first issue of the first volume of Phys-
iological Reviews was announced together with
the encouraging report that subseriptions had |
so far exceeded anticipation that reprinting of
the first number had already been accomplished.
The following board of editors for Physio-
logical Reviews for the year 1922 was reported
by the council:
William H. Howell, Baltimore, chairman;
J. J. R. Macleod, Toronto; D. R. Hooker, Balti-
more; Reid Hunt, Boston; Frederic 8S. Lee, New
York; L. B. Mendel, New Haven; H. Gideon
Wells, Chicago.
10. The following officers of the society were
elected at the business meeting on December 29:
J. J. R. Macleod, University of Toronto, presi-
dent; C. W. Greene, University of Missouri, sec-
retary; Joseph Erlanger, Washington University,
treasurer; J. A. E. Hyster, University of Wis-
consin, member of the council for the years
1922-25
22-25.

and to the loeal committee for the splendid facili-
ties offered for the scientific meetings, and for
the cordial hospitality extended to members
attending the meetings.

SCIENTIFIC SESSIONS
The scientific sessions of the annual meeting
were of high merit throughout. Perhaps the
SCIENCE
[Vou. LV, No. 1435
most profitable feature of the meeting was the
vigorous discussion which characterized a large
majority of the subjects presented. Too many
themes were introduced for the time available,
thus crowding the program. It was evident
that more restriction would have to be used if
representative reports of the activities of Amer-
ican physiologists are to be discussed within
the limit of a three days session. The entire list

City, Mo., for twenty-three years; more recently Vice-Principal; Author
of “‘Chemistry for Nurses,” etc.
461 pages, 514 x 714, with 72 illustrations. Price, cloth, $3.50.
This is an elementary text book for secondary schools and for those who
desire an up-to-date work that will meet their everyday needs. Just from
the press.
In his preface the author says: “Permit me to say that to me it has never
seemed necessary for a high school chemistry to present a mere skeleton of
the most interesting of sciences when that skeleton may just as easily be
clothed with wonderful symmetry and charming beauty. On the contrary, it
has always seemed that a text for secondary schools may and ought to be a
readable book just as well as one merely surfeited with facts. . . . Such is
the attempt of this text, to present the chemical facts of everyday life in a
readable form and by so doing make them interesting.”
The author's extensive experience as a writer and lecturer on chemistry
eminently fits him to prepare a book especially suited to the needs of ele-
mentary colleges. Teachers are requested to write us.

SHARPLES SUPER-CENTRIFUGE
MEDICAL LABORATORY MODEL
THE TEST
IN OUR STOCK FOR IMMEDIATE SHIPMENT
OF SERVICE
The Sharples Laboratory Super-Centrifuge is an instru-
ment for the application of very high centrifugal force to
liquids. The machine does not resemble the tube or bottle
centrifuge but is continuous in its operation—liquid is passed
continuously through the rotating member where it is sub-
jected to a force of 41,250 times the force of gravity, and the
liquid is then continuously discharged. In this way the volume
’ of liquid that can be handled per hour is limited only by the
rate at which a proper centrifugal treatment can be effected.
In the M. L. (Medical Laboratory) Model, for Bac-
tertological and Serolegical Work, the bowl is provided
with one outlet and with one collecting cover and delivery
spout. The M. L. Model has been widely used in U. S. Army
and other laboratories in the preparation of pneumococcus
vaccine and by the large manufacturers of other biological
preparations in the separation of various immunitive sera and
the collection of bacterial matters, as well as for the clarifica-
tion of agar, of gelatine, of broth, and other components of
culture media.

steam or compressed air turbine drive for continuous operation at a maxi-
mum speed of 40,000 r.p.m., requiring a steam pressure of 22 lbs. and con-
suming 100 lbs. of steam per hour. When operated by compressed air
ihe same pressure is required and the consumption is 16 cu. ft. of air per
$160.00
NOTE—Where neither steam nor compressed air is available, the centrifuges can be operated with crank for
hand drive, by which method an approximate maximum ed of 25,090 r.p.m. is obtainable; or with electric
d by which method an approximate maximum speed of 36,000 r.p.m. is available. A motor of 4 h.p., with
1 ed of 1750 r.p.m., and a three-inch pulley is require As the great advantage of the super-centrifuge re-
sults from the high speeds obtainable with the turbine drive, we furnish the hand drive and electric motor drive
on special order only.

Third Edition
AMERICAN MEN OF SCIENCE
A BIOGRAPHICAL DIRECTORY
EDITED BY J. MCKEEN CATTELL AND DEAN R. BRIMHALL
The third edition of the Directory contains about 9,600 sketches as compared with
4,000 in the first edition and 5,500 in the second edition. The work should be in the
hands of all those who are directly or indirectly interested in scientific work.
(1) Men of science will find it indispensable. It gives not only the names, ad-
dresses, scientific records and the like of their fellow workers, but also an invaluable
summary of the research work of the country, completed and in progress.
(2) Those interested in science, even though they may not be professionally en-
gaged in research work, will find much of interest and value to them in the book.
(3) Executives in institutions of learning and others brought into relations with
scientific men will use the book constantly.
(4) Editors of newspapers and periodicals will find it to be one of the works of
reference that they will need most frequently.
(5) Libraries will find the book to be a necessary addition to their reference
shelves.

Serological Water Bath of Precision
Electrically heated and temperature controlled serological water baths capable of
operating at 37.5 degrees Centigrade or 56 degrees Centigrade, either temperature may
be obtained by a simple turn of the indicative snap switch. The Wassermann test and
inactivating work may be accomplished in the same bath. An Immersion electric heater
which is entirely surrounded by water and extends the full length of the bath is used.
The thermostats are the multiple contact type, capable of repeated heating and cooling
without changing the adjustment. Should other working temperatures be desired the
adjustment screw on the thermostat permits the temperature to be readily changed. Baths
may be had from stock in the following sizes:

HIGH VACUUM PUMPS
Whenever in lecture-room or laboratory practice, really high
vacuum is required, we recommend the Condensation Pump devel-
oped by Dr. Irving Langmuir of the General Electric Company—believ- _
ing it to be superior to any other as yet obtainable.
The Langmuir Pump operates with surprising rapidity, and there
seems to be no practical limit to the degree of exhaustion that can be |
produced.
Some form of auxiliary pump must be used; and for that purpose
we offer a special G.E. two-stage oil-sealed mechanical pump, which |
is capable of producing a vacuum of
0.001 mm. when used alone.
The picture shows a complete out-
fit comprising Langmuir Condensation |
Pump, two-stage auxiliary pump and
% H.P. motor—all mounted together on |
one base.
