THE RELATION OF CHEMICAL LABOR-
ATORIES TO THE NATIONAL
WELFARE}?
For two years and a half the world has
been in a ferment. On the basis of an inci-
dent which now seems trivial, the mutual
jealousies and distrust of the nations of Eu-
rope precipitated a war in which the inter-
ests of all the nations of the world are in-
volved. Those of us who think that our
race is progressing toward better condi-
tions can not but believe that there will
grow out of this war some better method of
settling differences between nations. The
duel as a means of settling private quarrels
has long since disappeared in England and
America. It must surely cease as a means
of settling quarrels between nations. It
seems certain that the time will come when
the world will look back to these years as a
time of madness like the madness that drove
men to the crusades of the middle ages.
With all the loss and waste and dreadful
suffering of these years the nations of the
world are learning some lessons which
would not have been learned in times of
peace. Russia has solved her liquor prob-
lem for the time being. Germany enforces
a democratic equality in the distribution of
food which is beyond the wildest dream of
the socialists. Bread is distributed by
cards and the wealthiest citizen can get no
more than the day laborer. England has
solved the problem of the unemployed—
there is no longer a ‘‘submerged tenth’’ for
whom conditions are utterly hopeless. One
of my friends who has been in London with

his family reports that his wife was com-
miserating her charwoman on the suffer-
ing of the war, when the latter replied:
‘It’s not so bad—a pun’ a week and the
man away from home—it’s too good to
last.’’
In America, too, we are learning some
lessons—among others that our industrial
independence, at least in the matter of dyes
for our textiles, is of some importance.
If we try to find a single word which ex-
presses that for which all of the warring
nations are striving it is efficiency. It
seems very dreadful that the desire to
slaughter our fellow men should be the in-
centive, and if we did not believe that the
lessons learned under the stress of war will
remain during the long years of peace that
are to follow, we might well wish for the
good old times before scientific efficiency
was thought of. But whether we will or
not a new sort of efficiency has come to
stay and it is worth our while, here in
America, to grasp its meaning and to look
for the foundation on which it has been
built. fi :
I see with the eyes of a chemist, of course,
and shall draw my illustrations from the
science which I know best, but much that I
have to say applies to other sciences as well.
A little less than one hundred years ago,
shortly after Europe had settled down
from the tumult of the Napoleonic wars a
young German doctor of philosophy, not
yet out of his teens, went to Paris to study
chemistry and succeeded in gaining admis-
sion to the private laboratory of Gay Lus-
sac. lLiebig was a born chemist, if ever
there was one, and had worked with things
chemical from early boyhood. But even
Liebig needed the inspiration of contact
with one of the master chemists of his time,
and this Gay Lussae gave him. After a few
months he returned to Giessen and there in
a laboratory which was new of its kind in
university life he gathered about him an
[N. 8. Von. XLVI. No. 1175
enthusiastic group of young men who came
to him for the study of chemistry. The lab-
oratory was very crude and primitive in
comparison with the palaces of science
which we build to-day, but out of that lab-
oratory went influences which have spread
over the whole world—hiebig’s idea of a
laboratory was not that it is chiefly a place
for teaching what is already known, but
rather that it is a workshop where teacher
and pupil are striving together to learn
something new from the great book of na-
ture. Very soon many similar laboratories
sprang up and within a few years Germany
became the country to which young men re-
sorted from all over the world for the study
of chemistry.
A. W. Hofmann, one of the talented
young men of the Giessen group, was called
to London by Prince Albert in 1845. There
he taught in the college of chemistry. He
employed as an honorary assistant, some
years later, a young man by the name of
William H. Perkin. Young Perkin became
so interested in the subject that he was not
content merely to work with Hofmann dur-
ing the day, but he fitted up a private lab-
oratory at home where he could work at
night. Here he tried to do some experi-
ments in the hope of obtaining a synthesis
of quinine. His first experiments gave an
unattractive reddish brown precipitate of
the sort that most chemists would pass by
as hopeless. He became interested, how-
ever, and tried similar experiments with a
simpler substance, aniline. The product
was at first still more unpromising, but on
further examination he found that it con-
tained a beautiful purple coloring-matter
which was capable of dyeing silk and other
textiles. It was in fact the substance we
now know as the ‘‘Mauve dye.’’ Perkin,
then a lad of only eighteen years, con-
ceived the daring idea that this color might
be put to practical use. Fortunately his
father had faith enough in his ability to
Juty 6, 1917]
furnish him with the necessary financial
assistance. It was a new thing under the
sun and it is fascinating to read of the diffi-
culties met and overcome in developing the
industry of the coal-tar dyes. The benzene
which is now separated from coal-tar to the
amount of thousands of tons annually was
not to be had as a definite product and it
was necessary to invent the machinery and
apparatus for carrying out on a large scale
operations which, hitherto, had been tried
only in test-tubes. Even when the new dye
had been made, the dyers, who were accus-
tomed only to vegetable dyes, could not use
the product and Perkin had to go into their
dyehouses and teach them how to handle
the material. All of these difficulties were
finally overcome and a successful founda-
tion was laid for a great industry, which in
less than a generation revolutionized the
artistic beauty of our wearing apparel.
A few years later two German chemists
solved the riddle of the structure of aliza-
rin, the coloring matter of madder root,
and showed that the dye could be made
from the anthracene of coal tar. They did
not, however, put the production of the ma-
terial on a commercial basis and here,
again, it was William H. Perkin who
worked out the economic details of manu-
facture in his factory.
With such a beginning it would have
seemed that England must be the leader in
the manufacture of artificial dyes, but long
before the end of the nineteenth century
Great Britain had lost all her initial ad-
vantage and Germany was preeminent in
the production of synthetic colors.
When we look for the reason for this sur-
prising result we find it almost entirely in
the laboratories founded on Liebig’s ideal
—laboratories where students learned the
chemistry already known, it is true, but
where, much more than that, and as their
prime object, teachers and pupils gave
their energies intensely and incessantly to
SCIENCE | 5)
the development of an ever-changing sci-
ence. Young men trained in such an at-
mosphere proved to be the very ones who
could solve the varied problems of an in-
dustry which is so intimately connected
with investigations in pure science. In ad-
dition to the supply of trained chemists fur-
nished by the universities there grew up a
most intimate connection between the uni-
versity laboratories and the factories where
dyes were made. An illustration will help
to make this clear. Kekulé, one of the men
who worked with Liebig in Giessen, pro-
posed his theory of the structure of benzene
in 1865. This has become, perhaps, the
most important single thought guiding the
work of the color-chemists even to the pres-
ent day. Baeyer, who had studied with
Kekulé, took up, in the same year, some
work on isatin, an oxidation product of
indigo. He tells us with what pleasure he
had spent for a piece of indigo a birthday
present of two thalers, given him when he
was thirteen, and with what a feeling of
reverence he drew in the odor of orthoni-
trophenol while he was preparing isatin
from it by the directions which he found in
an organic chemistry.
After working upon isatin and other de-
rivatives of indigo for four years with good
success Professor Baeyer dropped the sub-
ject for eight years because his former
teacher Kekulé published a paper in which
he announced that he was attempting a
synthesis of isatin. It was evident that
Kekulé did not succeed and in 1877 Baeyer
felt justified in taking up the subject again.
Three years later he discovered a synthesis
of indigo which was of sufficient promise
for a patent and the Badische Anilin Soda
Fabrik began at once an attempt to put the
synthesis on a manufacturing basis. But a
successful synthesis in the laboratory is
very different from successful production
in a factory. The chemists of the factory
worked over the process from every pos-
4 SCIENCE
sible point of view for fifteen years. The
various steps in the process were greatly
improved and more than a hundred patents
were taken out, but it was never possible to
convert Baeyer’s synthesis into a successful
manufacture of indigo on a large scale.
The original material required for that
synthesis is the toluene of coal tar and the
annual production of this substance would
be sufficient to produce only about one
fourth of the indigo required in the world.
As toluene is used in the manufacture of a
great variety of other dyes and compounds
it is evident that any considerable use for
the manufacture of indigo would cause
such an increase in price as automatically
to stop the manufacture. No manufacture
of indigo could succeed unless the dye were
made at a price to compete with the agri-
cultural production in India.
The factory found its way out of this cul-
de-sac by means of a discovery made by
Professor Heumann in the chemical labora-
tory of the Polytechnic at Zurich, Switzer-
land—a laboratory which has given us
many brilliant discoveries in chemistry and
which is conducted on a high scientific
plane, not on the theory that it must devote
itself to so-called practical problems. By
combining Heumann’s discovery with
another made by Hoogewerf and van Dorp
in a laboratory in Holland it became pos-
sible to manufacture indigo with naphtha-
lene of coal tar as the starting-point.
Naphthalene, known to us all in the fa-
miliar moth balls, is abundant and cheap.
Even with the aid of these fundamental
discoveries from the university laboratories
the chemists of the factory worked inces-
santly upon the problem for seven years
before they felt sufficiently sure of their
ground to recommend the building of a
plant for the manufacture on a large scale.
Two incidents of the development are of
sufficient interest to deserve mention. The
first step in the process is the oxidation of
[N. 8. Vou. XLVI. No. 1175
naphthalene to phthalic acid. The proc-
esses which had been used before that were
too tedious and expensive. In the course
of a systematic examination of all possible
methods for cheapening the process a chem-
ist accidentally broke a thermometer in a
mixture of naphthalene and sulfuric acid
which he was heating. The mercuric sul-
fate which was formed proved to be the
needed catalyst to hasten the reaction and
the details of a successful process for the
oxidation were soon developed. But, as is
so often the case, the solution of one prob-
lem brought out a second difficulty.
Strong sulfuric acid is required for the
oxidation and this is reduced to sulfur di-
oxide, which it is necessary to recover and
convert back into the strong acid by oxida-
tion with air. This led to the transforma-
tion of the old and well-known contact
process for the manufacture of sulfuric
acid into a new and radically changed form.
Incidentally it may be remarked that the
new contact process soon found its way to
America and has been used to convert to
sulfuric acid the sulfur dioxide obtained as
the first step in the reduction of zine ores.
The strong sulfuric acid has been used, in
turn, in making dynamite.
Finally, in July, 1897, the preliminary
work was completed and the Badische Ani-
lin Soda Fabrik was ready to begin the
construction of the necessary factories. In
October, 1900, Dr. Brunck reported that
the firm had spent about eighteen million
marks or four and a half million dollars
upon their plant and that the production
had already attained a proportion which
corresponded with the natural production
from 100,000 hectares or nearly 250,000
acres of land. In reply to the suggestion
that the competition might prove disastrous
to the farmers of India he expressed the
hope that the land now used for the pro-
duction of indigo may be released for rais-
Juuy 6, 1917]
ing food stuffs, often sorely needed during
the famines in that country.
It has seemed worth while to consider
this development of the manufacture of
indigo in detail because it points out so
clearly the road which we must travel in
America if we are to succeed in the color in-
dustry. It is a lesson which American
manufacturers are learning, too, and this
promises well for the future. A manufac-
turer in Michigan has recently taken a
promising research worker in organic chem-
istry from the University of Michigan to
help him develop the manufacture of in-
digo, and another manufacturer in Buffalo
last summer called a man from the Univer-
sity of Illinois at twice the salary he was
paid there, to organize a research labora-
tory for the manufacture of dyes. In each
case the man secured his training in the
research work of a university laboratory.
At the beginning of the war we were
using dyes in the United States to the value
of about $15,000,000 a year. Of this
amount only about $3,000,000 worth were
made in America. Nearly all the rest came
from Germany. Textile industries having
a product worth hundreds of millions are
directly dependent on dyes and there is
searcely a person in this country who has
not seen in some form the effect of the
shortage. The dye manufacturers have
been alive to the situation and in another
year they will be able to furnish the quan-
tity of dyes required, though they will not
be able to furnish as great a variety as were
formerly used.
We have heard a good deal, in recent
years, about a scientific tariff commission.
The action of Congress last summer illus-
trates the need of such a commission. The
importance of making ourselves independ-
ent of other countries had become so evi-
dent that a bill was introduced providing
for an ad valorem tax on dyes of 30 per
cent. and a specific tax of 5 cents per pound.
SCIENCE 5
The specific tax is to continue for five
years. At the end of that time it is to be
decreased one cent a year till it disappears.
There is also a provision that if the Ameri-
can factories do not produce 60 per cent. of
the value of our home consumption at the
end of five years the specific duties are to
be completely repealed. While the specific
duty is only two thirds of the amount which
had been recommended by the New York
Section of the American Chemical Society,
it might, perhaps, have been sufficient if it
were not for another provision which was
allowed to creep in. Apparently at the in-
stigation of some large user of dyes, indigo,
alizarin and their derivatives were excluded
from the specifie duties. No logical reason,
whatever, can be given for this exclusion.
It must be due either to stupidity or to an
attempt to favor some special interests. As
this class of dyes constitutes 29 per cent. of
the whole and at least 10 per cent. of the
other dyes are covered by foreign patents,
it is evident that the hope that our fac-
tories will produce 60 per cent. of our dyes
in normal conditions of foregin competi-
tion is small.
Still other difficulties beset the industry.
The manufacturers of dyes in Germany
have very definite arrangements by which
one dye is made by one firm, another by a
second, and still another by a third so that
there is no real competition in the manufac-
ture of staple products. Such combina-
tions are fostered rather than hindered by
the German government, but similar com-
binations in this country are forbidden by
the Sherman law. The way out of this
difficulty seems to be in the first place a
census of dyes showing what dyes are used
and the quantities of each. Such a census
has already been prepared by the expert of
the Department of Commerce and Labor.
If we can combine with this, in accordance
with a suggestion of Dr. Herty, the editor
of our Journal of Industrial and Engineer-
6 SCIENCE
ing Chemistry, a frank statement by manu-
facturers, of the dyes which they intend to
make, we may find a solution of this prob-
lem which is in accord with the democratic
equality of opportunity which the Sherman
law is designed to conserve.
The greatest fear of the manufacturers is
that after the war they may be subjected to
an unfair competition designed to destroy
the new industry. The following story was
told during a discussion of the dyestuff sit-
uation which was held in New York in Sep-
tember. Mr. Dow, of Midland, Michigan,
discovered a good many years ago that the
salt brines of Michigan contain enough bro-
mine so that the element can be economically
produced, and in the course.of a few years
he developed the manufacture to such a
point that he shipped some bromine to Ger-
many. Not long after a German appeared
at his works in Midland and said to him:
“*T have conclusive evidence that you have
been selling your bromine in Germany.
Didn’t you know that you can’t do that?’’
Mr. Dow replied that he knew of no law
against it. The German said ‘‘Well you
ean not. If you do, we will sell two pounds
of bromine in America for every pound you
sell in Germany.’’ Mr. Dow paid no at-
tention to the threat but went on with the
production of bromine. Some months later
when he was in Texas on business he re-
ceived a telegram ‘‘Bromine is selling at 15
cents.’’ A normal price is 75 cents. Mr.
Dow closed his story at this point. The rep-
resentative of the German Kali-Industrie,
who was present, got up and asked him:
“Well, wasn’t it satisfactorly adjusted ?”’
But he made no reply. I am fortunate
enough to have heard the rest of the story
—which is known to a good many outsiders,
so I am betraying no confidence in telling
you. Mr. Dow stopped selling bromine in
America and sent his whole product to Ger-
many. It was not long before the German
manufacturers were ready to come to
[N. S. Von. XLVI. No. 1175
terms. Before the war Germany was man-
ufacturing three fourths of the coal-tar
dyes used in the world and we may be sure
that she will not easily relinquish her posi-
tion of preeminence in this field. Her
manufacturers will surely attempt to de-
stroy our manufacture of dyes by the same
methods which were used to stop the manu-
facture of bromine—by the so-called
‘‘dumping’’ of materials here at prices be-
low the cost of production. Laws have
been passed by Congress imposing severe
penalties for such practises, but some of our
manufacturers are very sceptical as to their
efficiency. We are not in as favorable a
position to compete in the making of dyes as
Mr. Dow was for the production of bromine.
I think it is clear from what has been
said that the manufacture of dyes rests at
its foundation upon the research work done
in the chemical laboratories of the German
universities and that we may trace it back
very directly to the days when Liebig re-
turned from France with the inspiration
which came from Gay Lussac, and founded
the laboratory in Giessen. One of the most
important factors in the dreadful efficiency
of Germany during the last three years
may be traced back to the same source. Not
a few of our leading men have emphasized
the advantage of developing the dyestuff
industry in America because the men
trained in this industry will be most com-
petent to handle the manufacture of ex-
plosives in case of war. Personally I have
a strong hope that at the close of the war
the world will be organized on the basis of
justice instead of force, but for the present
we can not ignore such arguments.
I wish to congratulate you on the com-
pletion of this laboratory at a most oppor-
tune time. We are in the midst of a very
rapid development of our chemical indus-
tries. New lines of manufacture are being
established and old lines are being rapidly
developed. Manufacturers realize as they
Juny 6, 1917]
have never done before how much chemis-
try can contribute to their success.
At the risk of seeming personal I will
give a few illustrations of how chemical re-
search in a single laboratory has demon-
strated its value under American condi-
tions.
A young man graduated from the course
in chemical engineering at the University
of Illinois in 1910. Soon after he was em-
ployed by a manufacturer of cement in the
state of Washington. Something had gone
wrong in the factory and hundreds of bar-
rels of cement were rejected because the
material did not meet the specifications.
The young graduate, trained in methods of
research, soon found the cause of the diffi-
eulty and corrected it and the firm has con-
tinued in the successful manufacture ever
since.
In 1907 a graduate of Worcester Poly-
technic Institute who had spent one year at
the Massachusetts Institute of Technology
came to Illinois as a research assistant. He
completed his work for the degree of Ph.D.
three years later and was continued as an
instructor and later became assistant pro-
fessor in charge of the division of organic
chemistry. In 1916 one of the oldest of the
firms manufacturing dyes in America
searched the country over to find a man to
organize their research laboratory. They
selected this man, not because of any ex-
perience which he had had in industrial
work, but because of his record as a re-
search worker in pure organic chemistry
and because of his ability to apply the prin-
ciples of physical chemistry to this field.
Another young man, a graduate of Ober-
lin College and trained in research by EKd-
gar F. Smith, of the University of Pennsyl-
vania, came to Illinois in a subordinate
position in 1907. During the eight or nine
years following he became one of the lead-
ing workers in this country in researches
upon the rare earths, and he was gradually
SCIENCE 7
advanced to the position of professor of in-
organic chemistry. Two or three years ago
he was asked by a firm in Chicago to assist
them in the details of an important applica-
tion of tungsten to an industrial use. He
solved the problem and the result proved to
be of large commercial value. Last year he
was asked by the firm to organize a research
laboratory to study the application of rare
metals to industrial uses.
Another chemist who graduated at IIli-
nois and afterwards took his degree of
Ph.D. at Wisconsin is now state food com-
missioner of Illinois. There is not a man,
woman or child in the state of Illinois who
is not directly or indirectly dependent on
this chemist for the maintenance of proper
standards for the food which he eats.
Many similar illustrations of the impor-
tance of trained chemists might be given by
any large university in America.
Such a laboratory.as this has three im-
portant functions to perform. It must
give an elementary knowledge of chemistry
to many students who will not become
chemists, but who yet should study the
subject because chemistry touches the life
of every one at many points. But this
part of the work will be very poorly done
if it merely imparts a set of so-called prac-
tical facts about every day life. Such
facts will be quickly forgotten, but chem-
istry, better than almost any other science,
furnishes a basis for clear scientific think-
ing and for students to acquire the habit
of reasoning from one point to another in
such a manner as to connect and combine
their knowledge into a coherent, logical
system. The discipline acquired in this
way is of greater value than any set of
facts that may be learned.
In the second place the laboratory will
train a few men who will find their way
into chemistry as a profession—it may be
into some of the industries to which I have
referred, or to become teachers, or to work
8 SCIENCE
in our experiment. stations over the im-
portant applications of chemistry to agri-
culture.
The third and most important function
of the laboratory is the contribution which
it makes to the growth of our science.
Here in Oklahoma you have many prob-
lems which can be solved with the aid of
chemistry. But just as Germany would
have failed utterly to reach her highest
achievements if her university professors
had confined themselves to so-called prac-
tical problems, so this or any other uni-
versity will fail if its staff does not devote
a considerable part of its energies to the
advancement of the science of chemistry
quite irrespective of whether industrial ap-
plications for the results of their researches
are apparent or not. No chemical labora-
tory has a right to call itself a university
laboratory if it loses sight of this, the
highest of its functions. A high-school
may devote itself exclusively to teaching
and a college may possibly do the same,
though of that there is serious question.
For the university there can be no ques-
tion. Ours is a vital, growing, rapidly
changing science and only those who are
intensely interested in its growth can prop-
erly teach and inspire those who are to go
out into the world and use for the ad-
vantage of themselves and of the state the
training they gain in university halls.

MILITARY GEOLOGY
Mopern warfare is a science, or rather an
application of many sciences, and therefore
it can afford to neglect no scientific field the
cultivation of which would make for added
superiority, in however slight degree. The
usefulness of certain sciences to the carrying
on of war is obvious or has been made so by
the conditions of the European contest: such
are surgery and chemistry; the military ap-
plication of certain other sciences, however,
[N. S. Vou. XLVI. No. 1175
is not so apparent and needs to be pointed
out from within the subject itself: thus it
is with geology. If the service that this
science can render to the country in time of
war be clearly established, then it follows
that geology will be incorporated in our plan
of military development and be called upon
to do its proper part in furthering the mili-
tary effectiveness of the nation.
This is a new role for geology, but a réle
already played and established in the theater
of war in Europe. Military geology is a
phase of applied science that has served the
warring nations abroad; it sees many duties
that it may perform for the United States.
In the first place, geological knowledge may
be employed to advantage by an army in the
field. “What a Geologist Can Do in War,”
is the title of a brochure prepared by R. A.
F. Penrose, Jr., for the geological committee
of the National Research Council and pub-
lished in April, 1917. This short essay in
scarcely more than a thousand words speci-
fies clearly the varied service that a knowl-
edge of geology can render, not only to the
army in camp, but to the army on the march
and in battle. The importance of this ser-
vice may be judged by observing some of the
problems arising in the course of field opera-
tions, which the geologist might appropriately
be expected to solve.
The selection of camp-sites involves prob-
lems in drainage and sanitary arrangements,
which become more difficult of solution in
marshy country; in arid regions the possibil-
ity of disastrous cloudbursts destroying
camps improperly located demands attention.
Trenches and tunnels must be placed, so far
as strategic conditions allow, in easily work-
able and drainable rock formations; while the
stability of slopes depends upon the material
in which the excavations are made. Ground
for artillery positions should be selected not
only from topographic considerations, but
also in respect to the firmness and elasticity
of the underlying rock, upon which the accur-
acy of fire will in part depend. The construc-
tion or repair of roads is a frequent military
need, the more important because of the nec-
Juuy 6, 1917]
essity for transporting heavy artillery, for
which the ordinary road-bed is inadequate.
Topographic maps carry a special meaning
for the trained geologist while geological
maps yield information of value in regard to
the strategic quality of the country of ad-
vance; even without maps the geologist can
draw inferences as to the ease and safety
with which the country ahead may be trav-
ersed. The vibration effects of prolonged
artillery fire in mountainous regions are
likely to cause landslides and _ snowslides,
which may prove disastrous if not anticipated
and guarded against; but vibrations arising
from the enemy’s fire may be turned to ad-
vantage through seismographie records,
showing the point of origin. Lastly, the
question of an adequate water-supply is ever
present, and the ordinary sources may often
be enlarged or improved upon by the location
of underground or artesian waters, while in
deserts the avoidance or chemical improve-
ment of waters too strongly alkaline becomes
frequently of paramount importance.
In these respects, then, an army without
geological knowledge is at a disadvantage;
for the problems mentioned are all within the
capabilities of the geological engineer and
some of them must remain unsolved if geol-
ogical advice is not at hand.
In the second place, an army employing
geologists in its field activities can facilitate
their effectiveness by maintaining a geological
department at home for the accumulation of
geological data and in particular of geologi-
cal maps covering all possible regions of mili-
tary activity. It is no small task to assemble
such material in form and quantity suitable
for use on short notice in any part of the
world. Such a department, therefore,
should be established in advance of field oper-
ations. Anew type of map recently employed
by physiographers, which shows by a block
diagram both the topographic features and
the underlying rock structures, would with-
out question prove of distinct advantage to
commanding officers planning a campaign
or executing field manoeuvers. Few maps
of this kind have ever been constructed;
SCIENCE 9
their preparation isslow and requires consid-
erable skill and knowledge. It would fall
within the province of the home office to
develop the usefulness of this sort of map.
The department also would appropriately
assemble information on the water resources
ot regions of prospective occupation, so
that the geologist in the field might be sup-
plied with such results of previous geologic
work, particularly in the enemy’s country, as
would facilitate his search for sources of
water-supply.
A third way in which geology can contrib-
ute to the military strength of a country is
through a study from a military standpoint
of its mineral resources, the raw materials of
war. In the United States, our mineral re-
sources have long been the subject of organ-
ized investigation on the part of the Geolog-
ical Survey, which has accumulated detailed
and accurate information regarding them of
the highest value at the present time. But
the investigations of the Geological Survey
have naturally been confined largely to the
economic and scientific aspects of its field, and
while much of its information can be quickly
interpreted in terms of military necessity, the
fact remains that this accumulated knowledge,
much of it of the deepest military significance,
has remained largely unused by military au-
thorities, and the United States to-day is un-
prepared in respect to a few mineral products
essential to war, such as nitrogen, potash,
manganese, nickel, tin, and platinum. This
country as a whole, however, is at a rel-
atively efficient stage of preparedness in re-
gard to her mineral industry, not because the
government has studied and anticipated her
military needs in this respect, but because re-
cent economic demands have in most partic-
ulars been analogous to impending war de-
mands, and hence the mineral industry un-
der present economic conditions is largely on
a military footing. But this does not ob-
viate the desirability of a further military-
geological study of our mineral wealth, for
conditions are ever changing and we should
anticipate every eventuality. In the future,
the military importance of minerals is bound
10 SCIENCE
to become of increasing significance with the
approaching depletion of those resources most
limited in quantity.
Finally the science of geology can be made
of increased effectiveness in military activ-
ites through instruction of officers and mili-
tary students in the elements of military geol-
ogy. This may be acomplished at no great
cost of time, by means of a brief and simple
course of instruction given at military
schools and training camps, supplemented by
a manual which may be studied in the field.
A knowledge of the properties and structure
of the common rocks, and of the dependence
of topography upon geologic conditions,
would be of repeated usefulness to the officer
and add to his efficiency. Some geological
knowledge, at least, he must pick up in a
practical way; its systematic acquisition
might advantageously be made convenient for
him.
Geology as a science is keenly alive to the
military service it can render. Many of its
members, its state and federal organizations,
and its principal societies, are actively at
work on plans for geologic research and the
immediate application of geologic knowledge
to the public welfare. But the most effective
service can not come from individual or class
initiative; it must await incorporation into
the general plans of governmental organiza-
tion, which to be effective will omit no advan-
tage that any department of knowledge can
give.
The problem facing the geologist, at the
present moment, is not so much to apply his
knowledge as to lead military authorities to
see clearly the service that he is prepared to
render.

SCIENTIFIC EVENTS
TUBERCULOSIS AND THE FRENCH ARMY
Dr. Herman M. Bices of the New York
State Department of Health, in the Survey,
discusses tuberculosis in France as influenced
by war conditions. According to a summary
in the Journal of the American Medical As-
[N. S. Vou. XLVI. No. 1175
sociation he states that while practically all
epidemic diseases which have heretofore been
scourges of armies in the field have been
brought under control in the present war,
tuberculosis has assumed a large part in the
sanitary history of ‘the present struggle.
France is the country that has been hard hit
in this respect, though Biggs says that from
such data as are obtainable Austria, Hungary,
Russia, and perhaps to a less extent, Ger-
many, have likewise suffered. As contrasted
with England with 1 death from tuberculosis
per thousand, New York State with 1.5,
France before the war had 8 deaths per thou-
sand, and in many cities the rate was higher.
Biggs attributes this largely to the fact that
even before the war France paid little sys-
tematic attention to tuberculosis. It had not
been recognized by the sanitary authorities,
and even now it is not a notifiable disease.
With the advent of the war and the rapid
mobilization of the troops, with examinations
which were not sufficiently rigid, and with the
strenuous conditions imposed on troops in the
field, latent or arrested tuberculosis mani-
fested itself among the troops, and by the end
of December, 1915, 86,000 soldiers had been
returned to their homes with active tuber-
culosis. In February, 1917, it was estimated
that 150,000 had been returned for this cause.
Biggs believes that in addition 3 or 4 per
cent. of the population who formerly lived in
the departments now in German occupation
have the disease, which would mean another
125,000, based on a population of 4,250,000.
Half of these live back of the German lines,
partly in their own homes, partly in concen-
tration camps and partly deported into Ger-
many, many of whom have been returned on
account of illness which made them a burden
to their captors. Biggs says that while he was
in Switzerland, of 20,000 of these people re-
turned, 5,000 were said to have tuberculosis,
though the estimated infection among those
deported into Germany has been placed at
5 or 6 per cent., which Biggs believes is con-
servative. Among the 350,000 or 400,000
French prisoners in Germany an estimate of
5 or 6 per cent. of tuberculous infection has
Juuy 6, 1917]
been made, although some French estimates
run as high as 30 or 40 per cent. Among the
four million men in the active French army
at present it is estimated that 4 to 1 per cent.
have tuberculosis. It is not believed that the
eases of tuberculosis among the civil popula-
tion have decreased since the war, and in the
remaining 30,000,000 not accounted for in the
foregoing figures, on a conservative estimate,
taking as a basis the prevalence of the disease
before the war, there would be at least 150,000
cases, making in all about 500,000 eases, or,
say, 400,000, to be extremely conservative, to
be dealt with if the war were terminated at
once. To deal with this vast number of cases
Biggs says there are at present the so-called
sanitary stations with 11,000 beds, which
number it is hoped to increase to 16,000 by the
end of the war, and a dozen or so well
equipped dispensaries. There are practically
no trained nurses or social service workers,
but a few women are being trained in a three
months’ course in the Laennee Hospital. Not
more than a dozen physicians are said to have
given any special attention tc tuberculosis,
few have had sanatorium experience and still
fewer are at all familiar with the tuber-
culosis work of others. The outlook, Biggs
feels, is not encouraging, though the French
government has partially realized the situa-
tion and is trying to meet the problem by the
organization of dispensaries in the populous
regions of France.
MEDICAL WORK IN BRAZIL
Dr. Grorce K. Stropr, a member of the In-
ternational Health Board of the Rockefeller
Foundation and who was one of the men sent
to Brazil to make a study of medical condi-
tions there, in a letter to Dr. David Riesman,
which is quoted in Old Penn, writes in part as
follows:
The work of the International Health Board is in
the hands of two of us down here. We have just
completed an infection survey in the state of Rio de
Janeiro, which has shown among 7,000 examina-
tions for uncinaria a percentage of positives of 82.
Malaria, I believe, is almost as wide-spread, and
the two are a heavy drain on the people. Our work
will shortly be extended to the states of Minas
SCIENCE 11
Geraes and Sao Paulo, which means the board will
be busy in this country for a long time. At the
present moment we are instituting an intensive
campaign in one county of the state which will aim
to cure and eradicate the disease in that area.
This we hope will serve as a demonstration and will
stimulate the authorities to continue the work.
There are many diseases found here with which
Iam not yet familiar; most important are Chaga’s
disease (trypanosomiasis) and leishmaniasis. Tu-
berculosis is, however, more important than either
of these and is being combated by voluntary or-
ganizations,
Medical schools are government institutions, and
the four leading ones are quite good. Six years
are devoted to the course, the first two being al-
most wholly given over to pre-medical work. The
graduate is not required to serve as an interne, so
that only about 30 per cent. take such work. In-
deed, in most of the hospitals internships are not
available. Research laboratories are few and far
between; the most noted is the Oswaldo Cruz In-
stitute, which I visited last week. Much good work
is produced here, but it is unfortunately very nar-
row in scope, entomology and parasitology being
the only fields that are tilled.
RECOMMENDATIONS OF THE THIRD INTER-
STATE CEREAL CONFERENCE
Iy view of the world shortage of cereal food
crops, which is likely to continue for an in-
definite period, the Third Interstate Cereal
Conference held at Kansas City, Mo., June 12-
14, urges the greatest practicable enlargement
of wheat acreage and would further make the
following recommendations:
1. To encourage a larger wheat production, the
producer should be guaranteed a minimum price,
such price to continue at least one year after war
is ended.
2. Early preparation of the land for small
grains, where these do not follow cultivated crops,
should always be practised. In the winter wheat
area it is very important that this be done im-
mediately after harvest.
3. Immediate action is required in providing
seed for the next crop. At harvest time it is
cheapest, and just before harvest seed in large bulk
can best be selected. State and federal aid will be
given in locating seed in localities of comparative
abundance for use in localities where it is sorely
needed. Clean seed, as free as possible from dis-
eases, should be selected and arrangements be made
for seed treatment.
12 SCIENCE
4, Varieties of grain best adapted for the lo-
cality should always be used. The agricultural
colleges and other state agricultural agencies will
inform the farmers of the existence of these va-
rieties and how and where to obtain the seed.
5. Every means should be employed to eliminate
weeds, by use of clean seed, crop rotations, early
cultivation above mentioned, and any special
methods reliably recommended for particular
weeds in different localities.
6. Seed testing for germination can well be
further emphasized at this emergency period. The
extension service, through county agents, should
bring this matter home to every farm.
7. Seed treatment will largely prevent certain
smuts and other diseases of cereals, and, as a real
war measure, we are bound to see that it is applied
as nearly as possible on every farm, thus increas-
ing our cereal production a hundred million bush-
els or more, in one season. By field demonstra-
tions the methods can and should be made plain to
all concerned.
8. The possible ravages of Hessian fly, chinch
bug, green bug, stored grain and mill products in-
sects, ete., must be kept also in mind and the
progress of and means of checking these insects
be communicated, so far as possible, in advance of
their local occurrence
9, As a means of reducing the great loss from
rust, it is urged that all common barberry bushes
(not the Japanese) and grass weeds harboring
cereal rusts, be eradicated, and that rust-resistant
cereal varieties be grown, if otherwise of good
quality.
10. It is a conservative estimate that 20 million
bushels of wheat and proportional quantities of
other cereals are annually lost by waste in har-
vesting and thrashing. This waste can and
and should be, in large measure, easily avoided.
A man and team are known to have cleared $27
to $62 a day from cleaning up after thrashers,
and, in another instance, last year in Kansas, $500
was gained by a man, with a team and fanning
mill, cleaning up after thrashing machine set-
tings, in three weeks’ time.
11. In the western and southwestern plains,
grain sorghums should be widely planted. In the
northern plains, in the drier districts, flax and,
under certain conditions, proso or Russian millet,
may be used to a similar advantage.
12. Suitable catch crops (such as cowpeas, soy
beans, sorghums, millet, flax and buckwheat)
should be grown on all lands on which staple crops
can not be seeded at the proper time or on which
they have been destroyed.

13. The increased use of corn, rice, grain, sor-
ghums, proso, barley, rye, beans, cottonseed meal
and peanut meal as substitutes for, or in conjunc-
tion with, wheat for human food is strongly recom-
mended. Information on this matter can be ob-
tained through the state agricultural colleges and
the United States Department of Agriculture.
ORGANIZATION OF THE ENGINEERING
COUNCIL
On June 27 was held the first meeting of the
Engineering Council. This body is a depart-
ment of the United Engineering Society and
has recently come into being as a medium of
cooperation between the four national engi-
neering societies. The function of the council
may perhaps best be described by the following
extract from the by-laws of the United Engi-
neering Society:
The council may speak authoritatively for all
member societies on all public questions of a com-
mon interest or concern to engineers.
The council is composed of twenty-four
members, five being appointed-by each of the
four founder societies and four by the United
Engineering Society. Its present member-
ship follows:
American Society of Civil Engineers.—J. F. Stev-
ens (Chas. Warren Hunt), George F. Swain, F.
H. Newell, Alex. C. Humphreys, F. D. Galloway.
American Institute of Mining Engineers—P. N.
Moore, 8S. J. Jennings, B. B. Lawrence, J. Parke
Channing, Edwin Ludlow.
American Society of Mechanical Engineers.—I. N.
Hollis, Chas. Whiting Baker, John H. Barr, A.
M. Greene, Jr., D. 8. Jacobus.
American Institute of Electrical Engineers—H.
W. Buck, E. W. Rice, N. A. Carle, P. Junkers-
feld, C. E. Skinner.
United Engineering Society—Clemens Herschel, B.
B. Thayer, I. E. Moultrop, Calvert Townley.
At the organization meeting held in the
rooms of the American Society of Mechanical
Engineers at 2.30 o’clock p.M., on the twenty-
seventh instant, the following officers were
elected: ;
President: I. N. Hollis.
Vice-presidents: H. W. Buck, George F. Swain.
Secretary: Oalvert Townley.
Executive Committee: The four officers named,
with J. Parke Channing and D. S. Jacobus.
Juuy 6, 1917]
The council discussed at length ways and
means by which the founder societies through
the council may be of use to the nation. The
unanimous desire to help the government in
the prosecution of this war resulted in a resolu-
tion instructing the executive committee to
cooperate with the government in procuring
the services of engineers, also the appointment
of a committee of three consisting of Messrs.
H. W. Buck, A. M. Greene, Jr., and Edmund
B. Kirby, to consider the best means of utiliz-
ing the inventive ability of members of the
founders societies.
The secretary was instructed to inform all
government bureaus that might be interested
in the organization of the Engineering Coun-
cil and its desire to be of assistance.

Promotion of Engineering Education will
be held in Washington, D. C., on July 6 and
7 in connection with the educational com-
mittee of the advisory commission of the
Council of National Defense, instead of in the
northwest as formerly planned. The topic
which will be discussed at this meeting is

Captain Ropert A. BarTLETT, on June 30,
telegraphed to the American Museum of Nat-
ural History from St. Johns, Newfoundland,
that he had taken command of the steam
sealer Neptune at that port, and that early on
July 1 he would steam for Sydney, C. B. The
eight tons of supplies shipped from New York
for the Crocker Land party are at Sydney and
will there be stowed on the Neptune. Captain
Bartlett expects to leave Sydney on either the
third or fourth of July for Etah, Greenland,
where the Crocker Land Expedition is now
quartered. Coincident with the leaving of the
Neptune, a special display devoted to the
Crocker Land Expedition has been installed
on the first floor of the American Museum of
Natural History. The location of the expedi-
tion, as well as the probable course of its re-
turn, is indicated on a globe. This exhibition
also includes pictures of the vessels which have
been sent to the rescue of the party—the Nep-
tune being the third. There is also on view a
canoe of skin, the kyak, in which Dr. Harri-
son J. Hunt, a member of the party, who ar-
rived a few days ago, made part of his perilous
journey from the base at Greenland to civiliza-
tion.
THE government of the Union of South
Africa has appointed an advisory board to deal
with the development of the natural resources
of the country. A special scientific and tech-
nical committee has been appointed to carry
JuLy 6, 1917]
out scientific investigations. This committee
consists of Mr. J. Burtt-Davy (botany and
agriculture); Mr. L. Colquhoun (chemistry) ;
Professor Young (geology); Professor Orr
(mechanical engineering) ; Mr. Bernard Price
(electrical engineering); Professor Beattie
(physics); Dr. Caldecott (metallurgy); Pro-
fessor van der Riet (chemistry); Professor
Malherbe (chemistry); Dr. L. Peringuey
(president of the Royal Society of South
Africa). The first step taken by the new com-
mittee has been to arrange for the preparation
of fifty-two reports by leading experts, dealing
with the available raw materials of South
Africa suitable for manufacture or export. It
is intended that these reports shall be pub-
lished for the guidance of intending manufac-
turers and other business men.
ARRANGEMENTS have recently been completed
for the establishment of a new department of
technical optics in connection with the Im-
perial College of Science and Technology at
South Kensington. According to a statement
in the London Times, the new department is
under the management of a Technical Optics
Committee, of which Mr. Arthur H. D. Acland
is chairman, and which at present consists of
18 members representing the Admiralty, the
Army Council, the Ministry of Munitions, the
Royal Society, the National Physical Labora-
tory, employers in the optical trades, glass
manufacturers and the Imperial College; while
two further members have yet to be elected
representative of glass workers and metal
workers. Mr. Frederic J. Cheshire has been
appointed head of the new department at the
Imperial College for a period of five years, with
the title of director of technical optics and pro-
fessor of technical optics at the Imperial Col-
lege. Mr. Cheshire has been associated with
optical instruments for many years at the
Patent Office, and, since the formation of the
Ministry of Munitions, has been deputy di-
rector-general of the ministry and technical
director of the optical department. He is
president of the Optical Society. It is antici-
pated that the organization of departments will
be rapidly completed, and that training will
begin at an early date.

Puans for medical work at the University
of Chicago, for which a fund of $5,500,000 has
been raised, contemplate two medical schools
and provision for research. One medical
school on essentially the same basis as that

DISCUSSION AND CORRESPONDENCE
AN INSTITUTE FOR THE HISTORY OF SCIENCE
AND CIVILIZATION
To tHE Epiror or Scrmnce: Dr. Sarton’s
plan for an Institute for the History of Sci-
16
ence and Civilization is one of the most impor-
tant and fruitful suggestions that have been
made for the advancement of knowledge. It
is to be hoped that the realization of his idea
might come soon and not have to wait until
that rather indefinite time—“ after the war.”
As Dr. Sarton very properly points out, it
would be particularly important and fitting if
this institute would be founded in this coun-
try at this time. That the United States, since
he wrote his communication, has entered the
war should make no difference. We are, as I
understand it, fighting for internationalism
and the founding of the institute now would
emphasize the international spirit of Ameri-
can science. \
What most particularly interests me in Dr.
Sarton’s plan is the place he gives to Bibliog-
raphy. Some readers of Sctence will perhaps
remember a couple of communications that the
present writer sent to this journal, now many
years ago, on the subject of a proposition for
an Institute for Bibliographical Research.
The two ideas should be combined. A third
idea might perhaps be added to this combina-
tion, namely the plan for a lending library for.
libraries, consisting of large and expensive
works, chiefly periodicals, transactions and col-
lections, just the kind of publications that the
Institute would need for the proper carrying
on of its researches; that the collections of such
a library would have to be made available to
students all over the country should make no
difference; it would emphasize the national
character of the Institute.
Now, as to Bibliography, one of the first
duties of the Institute would be to prepare an
adequate and, as far as possible, complete bib-
liography of the history of science. The “ List
of Books on the History of Science,” with its
Supplement and its companion “ List of Books
on the History of Industry,” published by The
John Crerar Library, is merely a bringing to-
gether of the material, and only part of the
material, for such a bibliography. Further-
more, bibliographical research must be one of
the principal methods of study in the insti-
tute. There should be a separate, specially or-
ganized, division for Bibliography, the func-
SCIENCE
[N. S. Vou. XLVI. No. 1175
tion of which should be not only to carry on
bibliographical research and publication, but
to give those who come to the institute what
they do not seem to get in American universi-
ties, a much needed training in the technique
of bibliographical compilation and recording.
It is not uncommon to find otherwise well
equipped scholars totally incapable, apparently,
of making bibliographical references in a con-
sistent and systematic way, though thoroughly
familiar with the bibliography of their subjects
and its byways. Those who are interested in a
few examples, will find them in an article by
the present writer in volume 7 of the Papers
of the Bibliographical Society of America, en-
titled “ Efficiency and Bibliographical Re-
search.”

POPULAR NAMES OF PLANTS
To tHE Eprror or Science: My attention
was recently called to an article in your issue
of February 2 concerning popular names of
North American plants. I especially noted
the following sentence:
It is clear, however, that pupils in the public
schools, as well as many of their teachers, do not
take any interest in or remember the Latin names
of plants. This being so, it is highly desirable that
every species of plant inhabiting the United States
and Canada should have an English name. It is
further desirable that the name should not be a
local one. ...
Several years ago when acting as editor-in-
chief of The Nature-Study Review, I took
interest in this question of popular names of
plants and discussed it with many competent
teachers of nature-study. I was forced to the
conclusion that in a large number of cases it
is possible and highly desirable that we should
make the English out of the generic names.
It is my observation that children learn these
names quite as easily as they do English
names with which they are not already
familiar. It is nonsense to claim that chil-
dren can not learn scientific names, for
example, chrysanthemum and hippopotamus.
As examples of familiar plants which are very
generally known by their scientific names or
JuLy 6, 1917]
by slight modifications thereof, I cite the fol-
lowing list: cosmos, centaurea, aster, alyssum,
ageratum, dahlia, canna, petunia, portulaca,
primula (primrose), salvia, verbena, zinnia,
impatiens, rosa (rose), gaillardia, heliotropium
(heliotrope), lobelia, lilium (lily), magnolia,
hyacinthus, chrysanthemum, anemone, oxalis,
wistaria, clematis, iris, spirea, peonia
(peony), forsythia, phlox, gladiolus, begonia,
asparagus, arbutus, coreopsis, smilax, trillium,
viola (violet), geranium, fuchsia, tulipa
(tulip), catalpa.
The suggestion that a species of Hrechtites
be called white fireweed and one of Hpilobium
be purple fireweed shows the absurdity of try-
ing to standardize local names, for there are
white species of Hpilobium. I am sure that
it is easier for school children to learn this
scientific name qualified by white or purple.
There are some interesting popular con-
fusions of scientific terms, e. g., syringa is a
popular name but unfortunately has become
attached to mock orange (Philadelphus) in-
stead of correctly to lilac, which as an Eng-
lish name has been applied to various kinds
of shrubs.

QUOTATIONS
TECHNICAL COLLEGE GRADUATES IN
WAR TIME
One of the first effects of the entry of
America into the war has been the volunteer-
ing of the graduating classes, nearly en masse,
throughout the country, into national defense
service, with a considerable number of enlist-
ments also in junior classes. This dedication
of our trained youth for the maintenance of
justice against brute-strength aggression is an
admirable thing, and no one who believes in
the ideals of young men will oppose it. It is
important to remember, however, that in-
judicious dedication to the world’s good may
actually do the world harm, and well-intended
action may by over-haste defeat its own
purpose.
War is a vast country-wide engineering
enterprise. Theoretically speaking, an all-
wise and powerful board of experts should de-
SCIENCE | 17
termine where each man and woman should
be posted in the great war chain of fighters,
for it is obvious that all specially trained
men, and particularly all technically trained
men, should keep at the posts where their
training is needed. It was an inevitable mis-
take made by our allies at an earlier stage in
the war which led many young physicians,
engineers, mechanics and valuable specialists
to rush as volunteers for the front. It may
overtax human intelligence to decide whether
any particular man of military age is more
needed at the front or at the rear. Mistakes
must occur, and many of them; but the tech-
nically trained men should be kept at their
profession unless there happens to be a super-
fluity of them. So long as there are earnest-
ness and determination to serve, they also
serve who only stand and wait. The junior
men in colleges, and particularly in technical
or medical colleges, will probably serve their
country better by working hard at their educa-
tional preparation than by abandoning their
college work before their training is com-
pleted. In general, however, every day’s work
‘done in any sort of productive employment
contributes to the war and therefore hastens
the end of the war. To do any useful thing
hard is to fight for the Allies—The Electrical
World.
DISCOVERIES AND INVENTIONS
Tue fact can scarcely be reiterated too fre-
quently that the government should extend
patronage to scientific investigations and me-
chanical inventions. Such a step is neces-
sary to promote the arts and industries as
well as to safeguard the nation in war. The
United States can no longer proceed on a
policy of bungling and neglect. Even the
Naval Consulting Board is inadequate to the
needs of the present emergency. The ability
of its individual members is high, but the
number of problems to which the board can
give its attention is limited by the restricted
membership.
The problems taken up by these most com-
petent experts are undoubtedly the most
urgent, but even on these particular problems
18
the country is not receiving the benefit of all
of the ideas worth considering. Independent
inventors are reluctant to contribute the fruits
of their efforts through a board whose mem-
bers are identified with large industrial con-
cerns. Unfortunately the sad story of the in-
ventor who receives no compensation for his
discoveries is only too well known. He lacks
the means for proper experimentation, as well
as for manufacture, and to obtain aid of the
capitalist he has to mortgage his prospects
too heavily.
A correspondent has suggested that prizes
should be offered to stimulate individual
enterprise, but only investigators having
private means would be in a position to com-
pete for such prizes. It would be a better
plan for the government to offer scholarships
and to maintain extensive research labora-
tories and shops where experimental work
could be done on a large scale. The work of
thousands of inventors is entirely wasted not
only because of duplication, but because they
are compelled to abandon their investigations
after making some discoveries of more or less
potential value. If records of their work were
preserved a new epoch in the advancement of
science might be inaugurated.
On April 2, W. H. Fauber, of Brooklyn, ad-
dressed a paper to the board of governors of
the Aero Club of America advocating the
creation of a government board of invention
and research in aeronautics. He also called
attention to the fact that it takes so long to
adjudicate a patent that the inventor is apt
to die during the process, and that an inven-
tion really is not protected unless it is in the
hands of a powerful corporation—The New
York Evening Sun.
SCIENTIFIC BOOKS
BOOKS ON FOOD
Witu1aMm M. Baytiss, the celebrated English
physiologist, has written a small volume en-
titled “The Physiology of Food and Economy
in Diet” (Longmans, Green and Co., 1917).
In a hundred pages he presents in clear, con-
cise and fascinating language the fundamental
principles of nutrition. Bayliss, though noted
SCIENCE
[N. S. Von. XLVI. No. 1175
for his work on the secretory glands and not
recognized as an expert on nutrition, has nev-
ertheless written with the appreciative touch
characteristic of the master mind.
Miss Winifred Stuart Gibbs, the supervisor
of home economics of the New York Associa-
tion for Improving the Condition of the Poor,
has made a valuable contribution to the food
problem in “The Minimum Oost of Living ”
(The Macmillan Co., 1917). The income and
expense accounts of seventy-five families re-
ceiving charitable aid, in the form both of ad-
vice and of money, were analyzed. A food al-
lowance made up from twenty-two items in
quantities calculated to suffice for the mainte-
nance of the family, as constituted, gave very
successful results. The author states: “ Any
one who has had experience in working with
the tenement population knows how intimate
a connection exists between food and the more
common diseases of poverty.” Thus, before
the allowance was granted, record after record
read, “ children anemic,” or “ mother suffering
from malnutrition.” But the allowance of a
minimum standard laid the foundation of good
health. “Such a sum can restore shattered
nerves and renew courage for a mother who
has been harassed by irregular and uncertain
payments of an income inadequate at best.
Such an assured minimum can change pale,
listless children into rosy-cheeked romping
boys and girls.” The “unit” of value for
food per “man” per day was taken at 3,000
calories and cost on October 1, 1916, thirty-
four cents. Children were rated according to
their ages at various fractions of a “man.”
These latter values appear to be minima. The
book tells of an inspiring deed of good work.
Another book, “ Food for the Worker,” by
Miss Frances Stern and Miss Gertrude T.
Spitz, with a foreword by Lafayette B. Mendel
(Whitcomb and Barrows, 1917), should fill a
great need at the present time. In this vol-
ume are found 120 household receipts, with
their food values, and the arrangement of these
recipes into different menus of balanced rations
for use during a period of forty-nine days or
seven weeks. It should be of aid to any eco-
nomical housewife, although it aims specifically
Juxy 6, 1917]
to designate the food requirement of a family
of five, containing three children whose ages
are between eight and sixteen. The diet pro-
vides 12,500 calories, contains 875 grams of
protein, and cost one dollar and six cents per
day in July, 1916. Of this, twenty-four per
cent. was spent for bread, thirteen per cent. for
milk, fifteen per cent. for meat, and the rest
for seventy other articles. The bread ration
contained 4500 calories or 35 per cent. of the
total energy value of the food. This kind of
information is of highest value to the house-
wife of limited means and can be successfully
applied by any intelligent person.
“The Mothercraft Manual,” by Miss Mary
L. Read (Little, Brown and Company, 1916),
presents, in language which is a delight, mod-
ern as well as old world knowledge helpful in
the, creation of the best environment for the
family and describes the care, nutrition and
development of the child.

THE THEORY OF SEX AS STATED IN TERMS OF
RESULTS OF STUDIES ON PIGEONS?*
At the 1911 meeting of this society, in
Princeton, I first made known the fact that the
sex of pigeons had been experimentally con-
trolled by Professor Whitman. The main fact
of method being briefly that from a family
cross practically only males, and from a generic
cross nearly all males, are produced; but if, by
special means the birds of generic crosses are
forced to excessive reproductive overwork then
the earlier eggs of such a series produce mostly
or only males, while the later eggs—from the
end of the series—will produce mostly or only
females. At the same time and place I made
to this society a first report upon the nature of
the results of my own studies upon the ova of
some of these sex-controlled series. These re-
sults then indicated—to quote from the pub-
lished abstract of that paper?—
1Paper read December 28, 1916, before the

ing).

that eggs (yolks) of smaller size, higher water-con-
tent and smaller energy-content (i. e., fewer units
of physiologically available energy) can be corre-
lated with maleness in the offspring. That eggs
(yolks) of larger size, lower water-content and
greater energy-content can be correlated with fe-
maleness in the offspring.
The later results, which I have from time to
time presented before this society and else-
where, have fully confirmed and much ex-
tended the evidence for that early announce-
ment of the nature of the germinal differences
which characterize the two sexes.
Though all of the several lines of study that
I have carried out on the doves and pigeons
have thrown light on the nature of germinal
and adult sexual difference most of these lines
of study were primarily designed to test the
possibilities of selective fertilization, differen-
tial maturation and elective elimination of ova
in the ovary as alternatives of a true sex-re-
versal or control. In view of the well-estab-
lished fact that the hetero-gametic sex produces
germs of two kinds—a sex-chromosome being a
differential already recognized—it has seemed
obligatory to supply decisive tests for the possi-
bilities just named. This has all been thor-
oughly done in the pigeons; the result has been
made possible because the female here is the
hetero-gametic sex, producing male and fe-
male ova, and we have here learned to identify
each of the two kinds. In these forms Whit-
man controlled sex and clearly demonstrated
the methods of control. In these same forms I
have for six years repeated the control and
fully confirmed the method. In addition I
have obtained adequate proof of the reality of
the sex-control as against the above-mentioned
alternatives and have further shown that in
this material sex is a matter of essentially all
gradations. And, of signal and unique im-
portance is the fact that all, or at least many,
gradations of sex are obtained from the same
pairs of parents. The outlines of these find-
ings have been published in several short papers
beginning in 1911;% the entire body of evidence

A still further fact of high importance has
been learned from the pigeons, namely, that
the sexual differences of the germs persist into
the adult stages of the two sexes.

Again, since my first report of these results,
several studies by other investigators on sev-
eral different groups of animals, have appeared
which in a most gratifying manner confirm the
point of view of my first communication, and
afford further evidence for the control and
modifiability of sex.
It is the purpose of this paper to arrange
some of the results of studies on the pigeon in
a diagram, upon which are properly placed
these various results of other investigators of
sex, in order to show that we are already in
possession of the skeleton of fact which is nec-
essary for a theory of sex that accords with the
most important fact of sex-reversal and con-
trol. And, that the theory of sex must be re-
stated—or rather may now be stated—in terms
that accord with the facts of sex-reversal is as
certain as is the fact of sex-reversal itself.
After our demonstration of the reality of sex-
reversal in doves and pigeons—even there had
had, to a considerable extent, fastened it. For,
at the same time that it was proved that our
experimental conditions break the correlation
which normally certainly does obtain be-
tween the chromosomal constitution of the
zygote and the prospective sex of the adult, it
was possible to identify those functional corre-
lations which here continue to exist (as in the
normal cases) and mark off the differences be-
tween the germs of prospectively different sex-
value. We know, till now, of no other material
in which this basal persistent function has
been definitely identified and quantitatively
measured in the germ. As I have elsewhere
pointed out, the basic fact is that the two
kinds of germs are differentiated by the degree
or level of their metabolism. When either of
these two kinds of germs is forced experimen-
tally into the production of the opposite sex,
the level of its metabolism is shifted to the
level characteristic of the germs of that oppo-
Juuy 6, 1917]
site sex. While the chromosomal correlation is
here forced to failure the metabolic correla-
lation here persists. The chromosomal consti-
tution is not an efficient cause of sex; it is but
a sign or index‘ and possibly an assistance in
the normal maintenance of that which is es-
sential—namely, two different metabolic levels.
But the requisite metabolic level of the germ
may be established in the absence of the usual
or appropriate chromosome complex, and the
sex of the offspring made to correspond to the
acquired grade or level of metabolism.
These facts which we consider firmly estab-
lished in the pigeons carry the further essen-
tial analysis of sex practically into the field of
physiology and bio-chemistry. Further analy-
sis of the basis of sexual difference—in germ
or in adult—is to be sought in studies of the
metabolic differences of the two kinds of sex-
germs, of adults of the two sexes, and of in-
dividuals of intermediate sex. Now that the
problem of sex has been shown to belong in the
field of metabolism we shall be able to note, in
connection with our diagram, that a number of
the requisite data bearing on germinal and
adult sexual differences are already at hand.
Turning now to the diagram we note that
egg and adult stages are considered. In the
eg of the pigeon we have identified maleness
and femaleness by three differentials. Female-
ness in the egg stage being accompanied by
low metabolism, lower percentage of H,O, and
higher total fat and phosphorus, or of phos-
phatides. Maleness is here accompanied by
high metabolism, higher percentage of water,
and lower total fat and phosphatides. Now
there are valid reasons for treating these three
differentials not as absolutely separate and dis-
connected facts, but rather as aspects or cor-
rollaries of the same fact. For example, a
high metabolism in a cell is consonant with
less storage of fat and phosphatides, and with
a more highly hydrated state of the cell-col-
loids. It follows that where data for either of
4Since the chromosomes are structural charac-
ters they can not be expected readily to alter their
numbers, etc., in response to new quantitative ley-
els attained (permanently) by the fundamniental
cell-functions.
SCIENCE 21
these three differentials are at hand, for either
the germ or adult of any animal, we have in
such data evidence of the kind we are looking
for, z. e., evidence for the association of a
given type of metabolism with the germ or
adult of a given sex.

For what forms then are such data available?
And, what is now known of the persistence of
this definite type of differentiation of the two
kinds of sex-germs into adult stages of the two
sexes? Recently Lawrence and Riddle®> have
shown that one of these differentials—or one
aspect of the differential which my own work
has demonstrated in the egg—is clearly con-
tinued in the blood of the adult male and fe-
male (see Table I.). Fowls were substituted
for doves in this case in order to increase the
size of the sample, and thus increase the ac-
curacy of the analytical results. In birds,
therefore, we have fairly clear evidence that
the metabolic differences of male and female
germs persist in the male and female adults.
In mammals too these aspects of sexual differ-
ences of the adults have been fully demon-
strated. Almost simultaneously with the
above determinations, data were published by
Goettler and Baker,® which as we have pointed
out, show that the blood of the human male
contains less fat, that of the female more.?
Further, the basal metabolism of the human
male and female has recently been accurately

determined by Benedict and Emmes;$ they find
that the metabolism of man is 5 per cent. to 6
per cent. higher than that of woman.
Have we any measure of either of our dif-
ferentials in any mammalian egg? I think
that the experiments on sex-determination in
cattle, together with an observation by van der
Stricht, afford some evidence that the water-
content of the male-producing egg is high, and
that of the female-producing egg is low.
Thury reported in 1862 that from fertilizations
made in the early period of heat in cattle an
excess of females were produced; and that
later (delayed) fertilizations give rise to an
excess of males. Similar experiments have
been four or five times repeated by others, and
these have all shown an excess of one or the
other sex in accordance with such early or late
fertilization.2 No one definitely knows whether
the ovum of the cow absorbs water in the Fal-
lopian tubes in this interval between ovulation
and fertilization, but we do know that every
amphibian, reptilian and avian egg that has
been investigated does absorb very appreciable
amounts of water while being passed from the
ovary to the exterior. And, van der Stricht
has described phenomena of growth or swell-
ing of the yoke granules in one mammal—the
bat—which, I am sure from my own studies on
yolk, indicate the taking up of water by the
egg of this mammal. It is highly probable,
therefore, that precisely that time relation
which leads to an excess of males in cattle is
preceded or accompanied by an increased hy-
dration of the ovum. In mammals therefore
there is some evidence that a shift of the meta-
bolic level—as indicated by one partly known
sex-differential—is associated with the ob-
served changes in the sex-ratio of the germs
which are thus modified. Further, in one
adult mammal—man—two of the three sex-
differentials have been definitely demonstrated.
These results for both the egg and adult
stages of the mammal are at every point in
8 Jour. Biol. Chem., Vol. XX., 1915. These au-
thors give references to earlier literature.
9 The use of the terms early and late fertiliza-
tions assumes that some ovulation occurs either im-
mediately before, or shortly after, the beginning
of heat.

complete agreement with our data for both the
ege and adult stages of the bird.
Experiments on the frog and the toad have
afforded evidence for the control of sex. This
evidence by many is not thought conclusive.
Though selective fertilization has been elimi-
nated as a possibility by Kuschekewitch there
remains the possibility of parthenogenetic de-
velopment to account for the excessive male-
production in his experiments with the frog.
But this appeal makes it impossible to explain
the great excess of females obtained by Dr.
King on the eggs of the toad, and leaves such
doubters to lean here upon the discredited staff
of selective fertilization—a proposition wholly
disproved for the related frog and for the
pigeon. E
How does this situation look in the light of
the sex-differentials already noted for birds
and mammals? Richard Hertwig,!® and later
Kuschekewitch,! allowed frog’s eggs to over-
ripen—a process during which the eggs take up
water—and obtained (in the case of the latter
author) in some cases a total of 100 per cent. of
males. Dr. King’? did the converse of this ex-
periment with toad’s eges—withdrawing water
from them before fertilization—and obtained
nearly or quite 90 per cent. of females in cases
where the mortality was less than 7 per cent.
According to our knowledge of the sex-differ-
entials in the pigeon’s eggs both of these ex-
periments might have been predicted to result
as these three investigators have reported.
In the spider-crabs Geoffrey Smith1% has
shown that both the blood and the liver of the
adult male crabs contain less fat than do the
blood and liver of the females. Here once more
the facts concerning one of the sex-differentials
is in complete accord with all the preceding
cases. In the parasitically castrated spider-
erabs Smith and Robson were able to show,
moreover, that the parasitized male crabs,
which under these conditions gradually as-
sume several female morphological character-

istics, are also found to have assumed the type
of fat metabolism which characterizes the nor-
mal female crab. How much these facts con-
tribute to, and how completely they adjust
themselves to, our own general theory, will be
realized only after a moment’s reflection.
A glance at the diagram indicates three
other groups of animals which experimental
work has thrown into the general question of
the control of sex. The information at hand
for these forms does not so expressly concern
the egg as does that from the preceding cases,
but all of these latter groups are concerned
with early stages—some of them with the
generation preceding the egg whose sex seems
influenced by conditions. The results of stud-
ies of the first of these groups—Hydatina—are
of such a kind as to show that they are in gen-
eral accord with the metabolic differentials of
all of the previously mentioned cases of sex-
control. One can scarcely doubt that change
of food, and increased oxygen supply are con-
sonant with increased metabolism, just as the
studies of Whitney"! particularly, and later of
Shull,® have shown that these changes lead to
the appearance of male-producing daughters.
The second of these groups—the Daphnids—
have been studied by three independent in-
vestigators who agree upon two points that are
of importance in the question of the control of
sex, and to the general theory of sex as stated
here, though the results throw little light on
precisely what is causally involved. Issako-
witch,1® Woltereck!? and Banta,!8 all find nu-
merous sex-intermediates in a material for
which all agree that the type of reproduction—
sexual or asexual—is influenced by environ-
mental conditions. All further agree that
“unfavorable conditions” (or is it a change
from favorable conditions?) tends toward sex-

ual reproduction, while “ favorable conditions ”
favor asexual reproduction.
In the third of these groups—the moths—
the studies of Goldschmidt, and Goldschmidt
and Poppelbaum,!® and the work of Machida,
have demonstrated again sex-intermediates of
various grades. Moreover, it has been shown
that from among the various geographical
races of moths certain matings can be ar-
ranged which produce rather definite types of
male- or female-intermediates—or sex-inter-
grades, as Goldschmidt elects to call them.
And further, from pairs involving still other
species still other levels or grades of sex-
intermediates may be freely obtained. A
more or less factorial basis of the phenomena
has hitherto been used in the discussion of
these results; but recently Goldschmidt? has
stated that “very important new facts will
be published later which will probably enable
us to replace the symbolistic Mendelian lan-
guage, used here, by more definite physico-
chemical conceptions.’”’ Such newer descrip-
tions—we would say—is wholly in line with
the requirements of present data on sex. In
Whitman’s and our own material it has been
clear from the first that the results far over-
step the possibility of treating them in Men-
delian terms, for it has been apparent from
the beginning that we have had to do not
with three or four points merely, but with a
flowing graduated line. In the work with the
moths, however, sex is clearly described in
quantitative terms,.and we can readily believe
that when the functional basis of sex can
there be identified, sex will be found to accord
with metabolic grades there, as it does else-
where.
Tt is clear then that all of the animal-forms
for which there is reasonable evidence of sex-
control show important correspondences with
the situation fully elucidated in the pigeons.
And that where the sex-differentials known to

exist in the pigeon’s ova have been traced in
adults of the two sexes, the parallel rigorously
holds there also. A general classification of
male and female adult animals on the basis
of a higher metabolism for the one, and a
lower for the other, was indeed made by
Geddes and Thomson?! many years ago.
There can now be little question that this
conclusion of these authors is a correct and
important one.
It remains to point out that another very
old, and much-worked line of investigation
supplies further confirmatory evidence for our
present point of view. Studies on the effects
of castration, gonad-transplantation, and
gonad-extract injection, constitute a large
body of observations which deal with sexual
phenomena associated with the internal secre-
tions of the sex-glands. These internal secre-
tions, let it be remembered, are themselves
metabolites, which have the capacity to influ-
ence the metabolism of some, many, or of all
the tissues with which they came in contact,
or which they may reach indirectly. 1> (OH).
For alkalinity,
(H) <1< (OH).
Finally, in any solution containing a
weak acid and its salts with one or more
bases, regardless of the other components of
the solution, the concentration of hydrogen
ions is approximately proportional to the
ratio of free acid to combined acid.
HA
=hax:
This relation, however, holds only when the
ratio of acid to salt is neither very large nor
very small.
It is therefore evident that in the solution
of any weak acid, when the quantities of
free and combined acid are equal, the value
of (H) is k; if the ratio of acid to salt be
10:1, (H) is 10 k, if the ratio be 1:10 (H)
is 0.1 k.
This is the total outcome of the theoret-
ical analysis so far as it is necessary for a
general understanding of the biological
problem.
We may now turn to the special case of
carbonic acid. For this substance the value
of k, expressed in our present units, is
about 5. Accordingly, in a solution of car-
(H)
JuLy 27, 1917]
bonie acid and bicarbonate, if the ratio of
acid to salt be 10 the concentration of hy-
drogen ions must be 50, if the ratio be 1
the concentration will be 5, and if the
ratio be 0.1 the concentration will be 0.5.
Thus we can see why carbonate solu-
tions are almost always nearly neutral
(e. g. 100 > (H) > 0.01), and, taking ae-
count of the universal distribution of free
and combined earbonie acid in the ocean,
in lakes and streams, and in all organisms,
we understand the primary cause of the
approximate neutrality of nearly all nat-
ural solutions, both organie and inorganic,
upon the earth. In blood the concentra-
tion of hydrogen ions is about one third of
the present unit, hence the ratio of free to
combined carbonic acid must be less than
1:10.
In general it is evident that when the
value of & for an acid is nearly 1 solutions
containing that acid and its salts will be
nearly always neutral; but that if the value
of k differs largely from 1 such solutions
will be nearly always appreciably acid or
alkaline.
Beside carbonic acid, there is but one
biologically common acid substance, viz.,
phosphorie acid after one hydrogen has
been neutralized by base as in acid sodium
phosphate, that possesses the value of k
nearly equal to 1. Most weak acids have
a value hundreds or thousands of times
greater. Phosphate solutions are therefore
commonly nearly neutral, and they share
with carbonate solutions the function of
preserving the constant alkalinity of the
body.
It is easy roughly to demonstrate the gen-
eral character of such acid-base equilibria
with the help of the phosphates. Thus,
for example, a solution of acid sodium phos-
phate has a faintly acid reaction, a solution
of ordinary sodium phosphate an alkaline
reaction, but almost any mixture of the
SCIENCE 79
two salts is neutral to ordinary indicators,
and will take up strong acids or alkalis
in large quantities without apparently
changing its reaction. Of course every
drop of acid or of alkali does change the
reaction, but the change is so slight that it
can not be detected by ordinary means.
This depends upon the fact that strong
acids and bases combine quantitatively with
the alkaline or acid phosphate:
HCl + Na,HPO,= NaCl + NaH,PO,,
NaOH + NaH,PO,= Na.HPO, + H,O.
Accordingly, there is only a change in the
ratio between the concentrations of the two
phosphate salts, and of hydrogen ion con-
centration in due proportion, according to
the analysis already given.
If the solution is supposed to contain
bicarbonates, as well as phosphates, the
above experiment fully illustrates the gen-
eral character of the process by which acids
are immediately neutralized in the body.
The proteins, to be sure, are also involved,
ut their share in the process is small,
though not physiologically insignificant.
Upon this physico-chemical basis the phys-
iological processes are erected. It is as a
means of restoring bicarbonate and alkaline
phosphate from the products of reaction
of these substances with acids, or as a means
to neutralize acid, and thus prevent its
reaction with \bicarbonates and phosphates,
that ammonia is produced in the meta-
bolism.
In like manner the acidity of the urine
is the result of the reversal in the kidney of
the reaction by which acids have been neu-
tralized inthebody. Inthe renal function
phosphates almost alone are concerned.
Therefore the process may ‘be described as
follows: In the blood, as the result of the
production of acid, a certain amount of al-
kaline phosphate has been converted into
acid phosphate, so that the ratio of acid
phosphate to alkaline phosphate has been
80 , SCIENCE
slightly inereased. (Under normal cir-
cumstances this change is probably in-
finitesimal.) The kidney now removes
relatively a siill larger amount of acid than
of alkaline phosphate, perhaps on account
of changes in the blood bicarbonate rather
than in the phosphate, and thus restores
the ratio of base to acid in the blood. Here
ihe essential factor is the ability of the kid-
ney widely to vary the ratio of acid to al-
kaline phosphate without large variation
of the hydrogen ion concentration of the
urine. This very important fact once more
depends upon the favorable value of k& for
acid phosphate.
It is because, in the normal individual,
both the production of ammonia and the
ratio of acid to alkaline phosphate in the
urine are variable within wide limits, and
can be made to conform exactly to the
varying ingestion and production of acid
in ‘he body, that the fundamental physico-
chemic2] apparatus can be kept intact and
accurately adjusted.
A further factor in the process is the
activity of the lung in excreting carbonic
acid. This substance is the chief excretory
product of the organism. As such it must
be eliminated promptly and completely.
Moreover, in that it leaves the body not
in aqueous solution and as an acid, but
almost exclusively in the form of gaseous
carbon dioxide, there is no possibility of
any variation of the permanent effect pro-
duced upon the reaction of the body by
the elimination of a definite amount of it.
In the final regulation by excretion it is
not, therefore, concerned. And yet it has,
in the process of excretion, a very impor-
tant role in regulating the reaction of the
body. This depends upon the fact that
carbonic acid is not only a waste product,
but also a normal constituent of the blood,
and, as such, a principal factor in the
physico-chemical regulation. Thus, if the
[N. S. Von. XLVI. No. 1178
ratio of carbonic acid to bicarbonates in a
normal individual were 1:15, a large pro-
duction of acid might cause a destruction
of a third part of all the bicarbonates, pro-
ducing in its place an equivalent amount
of free carbonic acid. This, if nothing else
occurred, would reduce the relative amount
of bicarbonates from 15 to 10, and simulta-
neously increase the free carbonic acid
from 1 to 6. The ratio would now be 6:10,
and since the hydrogen ion concentration is
porportional to this ratio, this ion would
suffer a nearly ten-fold increase of con-
centration. But at this point, or, more
strictly speaking, continuously during the
process, the excretory function intervenes.
There is a tendency for the respiratory
process to hold the tension of carbonie di-
oxide in the blood nearly constant. This
is the reason why carbonic acid has some-
times been thought the respiratory hor-
mone. Assuming that the exact quantity
of carbonic acid set free by the reaction of
neutralization were thus eliminated, the
ratio would be reduced to 1:10, and the
hydrogen ion concentration would rise but
one third above its original value. More
recent investigations, however, have shown
that a tendency to acidity is accompanied
by a lowering of the tension of carbon di-
oxide. Let us suppose that in this case
the tension was lowered one third. The
free carbonic acid of the blood would then
become 0.67 instead of 1.00, and the ratio
of acid to salt 0.67:10, which is exactly
equal to 1:15, the original ratio. Accord-
ingly, the hydrogen ion concentration
would be restored exactly to its original
value, and the regulation by excretion
would be quite perfect. Now there is
abundant evidence to show that something
very much like this is always occurring in
the body, and, on the whole, I believe that
the most delicate of all means to regulate
the reaction of the body is to be found in
Juty 27, 1917]
this variation of the tension of carbonic
acid during its excretion. Such consid-
erations have strengthened the hypothesis
that the hydrogen ion is the true respir-
atory hormone. Originally suggested as a
guess, this theory has been supported by
many investigations. But I think that it
marks the opening rather than the closing
of a chapter in physiology, for the subject
is involved in many complexities.
The whole physiological equilibrium may
now be concisely summed up. The hydro-
gen ion concentration of the body has been
seen to depend upon the ratio
H.CO;
NaHCO,
Acid reacting with this system causes a
diminution of the denominator and an in-
crease in the numerator of the fraction, the
value of the fraction increases, and with it
the hydrogen ion concentration. Here-
upon the lung reduces the value of the
numerator by diminishing the concentra-
tion of carbon dioxide in blood and alveo-
lar air, the value of the fraction is restored
more or less exactly to its original value
and with it the concentration of the hy-
drogen ion. But the denominator is still
below normal. To offset this, there occurs,
on the one hand, a production of ammonia
which takes the place in the urine of al-
kali existing as salt in the blood. This al-
kali recombines with carbonic acid, form-
ing bicarbonate, and thus increasing the
denominator. On the other hand, the kid-
ney removes less alkali in combination with
phosphates than exists in this state in the
blood. This alkali, too, helps to regen-
erate sodium bicarbonate, and thus to in-
crease the denominator. Both of these
processes are so regulated that the denom-
inator is restored to normal. The con-
centration of carbonic acid responds
through the activity of the respiratory
SCIENCE 81
mechanism, and the organism returns to
its normal state.
These processes, of course, go on simulta-
neously and not in succession. They are,
moreover, far less simple than such an
analysis admits, for on the one hand the
interaction of phosphates and proteins has
not been fully described, and, on the other
hand, many of these variations influence
other conditions and processes in the or-
ganism.
Among these effects are the influence of
carbonic acid concentration and of the hy-
drogen ion on the affinity of hemoglobin
for oxygen and on the volume of the red
corpuscles. More general is a necessary,
but at present indeterminate, effect on the
distribution of electrolytes in the body, on
the osmotic pressure, on the state of col-
loids, and on the volume. I fully believe
that such effects are real and that when
acid is produced through long periods and
in large quantities in particular organs or
tissues, as during diabetes, they may well
surpass the direct effects of the simple chem-
ical reactions of acid in the pathological
complex, and produce a condition very dif-
ferent indeed from that of experimental
acidosis. For in such conditions the whcle
physico-chemical composition of the cell,
its concentrations and colloidal equilibria,
might be sensibly altered.
But such guesses are one thing and the
detailed and very dogmatic speculations of
Dr. Martin Fischer cuite another. And I
feel obliged to say that there is not one
particle of evidence for his conclusions,
which are indeed inconsistent with, or
totally without bearing upon, all the exist-
ing . quantitative information that we
possess upon this subject.
mI
What then is acidosis? Evidently a con-
dition lacking necessary connection with
82 SCIENCE
the production of oxybutyrie acid or with
the magnitude of the hydrogen ion con-
centration in blood; still less a condition
involving the existence of acid in the blood.
It is often characterized by high urinary
ammonia, but sometimes this quantity is
low; the concentration of carbon dioxide
in the alveolar air is commonly low, but
one can not feel sure that this is invariably
the case; in acidosis the oxygen capacity of
the blood seems to be generally diminished,
but we do not yet understand this subject
well enough to be sure that compensatory
changes may not take place. ,Upon the
whole I think that we come nearest to cer-
tainty if we say that acidosis must involve
a depletion of the body’s alkali reserves,
and specifically a depletion of the bicar-
bonate of the blood. So long as this has
not taken place the pathological condition
can not amount to much, so far as the acid-
base equilibrium is concerned; when this
defect is established the whole chain of
causation, involving breathing, oxidation,
nitrogen metabolism, renal activity and so
on, has been set in motion.
The cause of the condition may vary
widely. It may be due to the production
of acid, or the-ingestion of acid, or to lack
of alkali in the food; it may be due to fail-
ure to eliminate acid, e. g., acid phosphate,
or to failure to produce and eliminate am-
monia; but so far as can be seen it must
always involve at least a diminution in the
concentration of bicarbonate in the blood.
As a practical maxim, we are therefore
fully justified in saying that acidosis is a
state of diminished bicarbonate in the
blood.
Accordingly, it may also be said that the
best means to the recognition of acidosis is
proof of diminution in the bicarbonate of
the blood. It is true that alveolar air, or
the oxygen capacity of the blood, or the
urinary ammonia, or the acidity of the
[N. S. Vou. XLVI. No. 1178
urine, or the excretion of acetone bodies,
may ‘be definitive in any particular case.
But a state of acidosis is certainly not
always dependent on some of these vari-
ables, and may possibly be independent of
all of them.
The most direct proof of diminution of
the bicarbonate of the blood is afforded by
an estimation of the capacity of the blood
for carbon dioxide at a specified tension of
the gas. This, or a related method, prop-
erly employed, will always give accurate in-
formation and need not make considerable
demands upon the technical skill of the
investigator.
But there is another method, consisting
of a physiological test of the greatest sim-
plicity and involving no experimental skill
at all, which seems often to lead to equally
trustworthy conclusions. 'The test depends
upon an observation made by Sellards and
also by Palmer and myself that in different
pathological conditions and in different in-
dividuals the amount of soda administered
by the mouth that is necessary to make the
urine alkaline is a very variable quantity.
Further extensive investigations of Dr.
Palmer’s have convinced me that this
phenomenon depends on nothing but the
retention of alkali by an organism whose
store has been depleted, until the normal
amount has Ibeen once more acquired. The
addition of five or ten grams of soda to the
food is enough to make the urine of a
healthy person alkaline, and if more than
that is retained, experience justifies the
conclusion that a state of acidosis exists.
This test also points to a rational treat-
ment of acidosis. For if sodium bicar-
bonate is administered at frequent in-
tervals in quantities just sufficient to make
the urine as alkaline as the blood, acidosis
can not exist. The reaction of the urine
can be followed closely enough even with
litmus paper, a so-called amphoteric re-
Juuy 27, 1917]
action indicating that sufficient alkali has
been provided, and if the reaction does not
become more alkaline than this there seems
to be no danger of injuring the kidney.
Of course this method may be inadequate
to cope with the more complex problems of
diabetic acidosis, and it is very doubtful
if the alkali can always penetrate in suffi-
cient quantities to the seat of acid pro-
duction. There is, moreover, no reason to
suppose that it can influence the cause of
the condition. Indeed this is rather a
matter of proper feeding than a thera-
peutic measure. For next to water and
sodium chloride the concentration of so-
dium bicarbonate is the greatest in blood,
and it seems not unreasonable to care for
a sufficient supply of this substance as one
does for a supply of water.
There is the more reason for bearing
these conclusions in mind because acidosis
is one of the commonest of pathological
states. Indeed I think that it is probably
more common than fever. Therefore one
may conclude that in serious illness the
test for acidosis should always be made,
especially because it is often a very simple
matter to repair the defect. And I think
there is some reason to suppose that such
action may occasionally be of the greatest
importance.
But the use of alkali must always be de-
liberate and founded upon the urinary re-
action, for too much alkali may be very
harmful indeed. As employed by Martin
Fischer in nephritis, experience has con-
vinced me that it is a source of grave
danger and, if possible, graver suffering to
patients who can often expect from the
physician little more than some relief from
pain. Yet even in nephritis there is at pres-
ent no reason to avoid the proper use of al-
kali. In fact, I have never known a kidney
to be unable to excrete a small excess of it,
and I think that we may therefore always
SCIENCE 83
undertake the administration of soda ac-
cording to the rule above laid down, with
the conviction that when the quantity of
sodium bicarbonate in the body is below
normal, no harm is to be expected from the
action of sodium bicarbonate.
Finally, if I may be permitted to express
as a precept my own conclusion of the
bearing of all these intricate facts upon
medical practise, it is as follows: The duty
of the physician is to discover that the
quantity of sodium bicarbonate in the
blood is diminished, to restore that quan-
tity to normal, and to hold it there. But
while restoring it, he must never increase
the quantity above normal. Thus found-
ing practise upon exact knowledge, upon
theory fully confirmed, and upon an under-
standing, however imperfect, of the organi-
zation of allthe manifold processes of meta-
olism, he may hope sometimes to block a
cycle of changes leading to final disinte-
gration, and perhaps more often to alle-
viate discomfort and pain.

SCIENTIFIC EVENTS
THE IRON INDUSTRY
ABNORMAL conditions prevailed in the iron
industry during the first half of 1917, mainly
on account of the war in Europe. At the
beginning of the year, when pig iron was
being made at the average rate of about 102,-
000 gross tons daily, the blast furnaces were
operated at slightly reduced capacity, accord-
ing to E. F. Burchard, of the Geological
Survey. This rate dropped to less than 95,000
tons daily in February, but in March the rate
rose to 105,000 tons daily, and in April and
May it stood at more than 110,000 tons, com-
pared with the maximum rate of 113,000 tons
in October, 1916.
The prospective ° blast-furnace capacity
seems not to have kept pace with the demand,
however, as is indicated by the enormous in-
84 SCIENCE
creases in price, especially since the United
States entered the war.
The total output of coke and anthracite
pig iron in the first five months of 1917 was
about 15,800,000 gross tons, compared with
about 16,175,000 tons during the correspond-
ing period of 1916, a decrease of about 2
per cent.
The quantity of iron ore from mines in
the Lake Superior region shipped from upper
Lake ports from January 1 to June 1, 1917,
was about 6,500,000 gross tons, compared with
slightly more than 10,100,000 tons for the cor-
responding five months of 1916, a decrease of
about 3,600,000 tons, or more than 35 per cent.
This apparently large decrease in ore ship-
ments from the principal producing region
was not due to inability to mine ore but
largely to the belated opening of Lake traftic
because of ice blockades and to many ore-
carrying boats having been put out of com-
mission through accidents.
Plans are being made by committees of the
Council of National Defense to increase ship-
ments of iron ore, coal and coke during the
remainder of the season through cooperative
methods, and possibly the June shipments will
nearly equal those of June, 1916. In the
meantime the blast furnaces have been draw-
ing on large stocks of ore at lower Lake ports
in order to offset the deficiency in upper Lake
shipments. Deferred shipments of coke and
other causes of traffic congestion have also re-
tarded operations at some furnaces.
Prices of pig iron at western Pennsylvania
furnaces have advanced since January 1, 1917,
61 to 77 per cent. and since a year ago 134 to
200 per cent. On July 3, 1917, basic iron was
quoted at Valley furnaces at $52 a ton, Bes-
semer iron at Pittsburgh at $57.95, and No. 2
foundry iron at $55, while at Birmingham,
Ala., foundry iron, which one year ago sold
at $14 brought $47 a ton. Low-phosphorus
iron has been quoted at $70 to $80 a ton.
Feverish buying of pig iron by private con-
sumers who were endeavoring to provide for
their present needs, as well as for their needs
far into 1918, has caused much of the recent
increase in price. The extent of the govern-
[N. S. Vou. XLVI. No. 1178
ment’s war needs for steel is not yet defined,
but increasing. Orders are being placed
slowly, however, and they should not inter-
fere seriously with deliveries of steel to private
consumers. As the government is not com-
peting in price it would seem that there may
be at least some warrant for belief that prices
may eventually adjust themselves without need
for further great inflation.

THE DANIEL GIRAUD ELLIOT MEDAL
AT a meeting of the council of the National
Academy of Sciences, held June 19, 1916, the
gift of Miss Margaret Henderson Elliot of
$8,000 to establish a fund in memory of her
father, Daniel Giraud Elliot, was accepted.
This money was given to be held in trust and
SCIENCE 85
invested in order that there should be an in-
come annually for a medal to be known as the
Daniel Giraud Elliot Gold Medal, and an
honorarium to be awarded by the National
Academy of Sciences.
The conditions under which the gift is to be
administered are contained in the following
two paragraphs of the deed of gift:
One such medal and diploma shall be given in
each year and they, with any unexpended balance
of income for the year, shall be awarded by the
said National Academy of Sciences to the author of
such paper, essay or other work upon some branch
of zoology or paleontology published during the
year as in the opinion of the persons, or a major-
ity of the persons, hereinafter appointed to be the
judges in that regard, shall be the most meritorious
and worthy of honor. The medal and diploma and
surplus income shall not, however, for more than
two years successively, be awarded for treatises
upon any one branch of either of the sciences above
mentioned. Professor Henry Fairfield Osborn, of
New York, the scientific director of the American
Museum of Natural History in New York City
and the secretary of the Smithsonian Institute at
Washington for the time being, are appointed as
such judges. Vacancies at any time oceurring in
the number of the judges shall be filled by the
council of the said National Academy of Sciences,
and in each ease of a vacancy it is the wish of the
said Margaret Henderson Elliot that the council
will, if practicable, appoint to the position an
American naturalist eminent in zoology or paleon-
tology.
As science is not national the medal and diploma
and surplus income may be conferred upon nat-
uralists of any country, and as men eminent in
their respective lines of scientific research will act
as judges, it is the wish of the said Margaret
Henderson Elliot that no person acting as such
judge shall be deemed on that account ineligible
to receive this annual gift, and the medal, diploma
and surplus income may in any year be awarded to
any one of the judges, if, in the opinion of his as-
sociates, he shall, by reason of the excellence of any
treatise published by him during the year, be en-
titled to receive them.
The council of the academy has accepted the
gift and has appointed as the three judges for
the bestowal of the medal and honorarium:
President Henry Fairfield Osborn, of The American
Museum of Natural History.
Secretary Charles D. Walcott, of the Smithsonian
86
Institution of Washington.
Director Frederie A. Lucas, of The American Mu-
seum of Natural History.
The income from this gift to the academy
will be sufficient to award the first medal and
honorarium at the April meeting, 1918. Dr.
Henry Fairfield Osborn has been designated
by the president of the academy to act as chair-
man.

DISCUSSION AND CORRESPONDENCE
MAN AND THE ANTHROPOIDS
In our current scientific literature one fre-
quently meets the assertion that man is a lin-
eal descendant of the anthropoid apes. The
evident implication is that the extant an-
thropoids, orang, gibbon, gorilla and chim-
panzee, are intended. Thus in the issue of
“ Scrncz,” of February 23 ultimo, Professor
Stewart Paton remarks:
The time is rapidly passing, as Yerkes has
pointed out, when on account of the disappearance
of the higher apes it will be possible to trace the
various gradations in our ancestral line. °
The correction of this common error lies
all along the line of technical evolutionary
thought from Huxley to the present, but it
does not seem to have penetrated popular sci-
ence. Our leading authority in this field,
Professor Duckworth, in his “ Morphology
and Anthropology,” Volume I, page 238,
Second Edition, 1915, writes:
We must conclude that the existing anthropoid
apes, constituted as they now are, did not figure in
the ancestral history of man.
This should relieve our anxieties regarding
“our ancestral line.”
While our knowledge of the anthropoids is
not as complete as we might wish, the whole
of it is against the supposition of the natives
of the Congo and of Borneo that man is
ascended from the anthropoids or the latter
are descended from man. The thraldom of
morphology accounts for much _ biological
belief both ancient and modern, but the sci-
ence of the present puts much more weight
on anatomy and physiology. It appears to
be a sound principle that groups showing in-
verse developments are not genetically related.
Duckworth points out some of these inversions
as regards man and the anthropoids, such
[N. S. Von. XLVI. No. 1178
as in dentition, in the spheno-ethmoidal angle,
and in the spheno-maxillary angle. Metchni-
koff, while he assumes as a hypothesis that
man is descended from “some anthropoid
ape,” pointed out that the present anthropoids
have the os penis which does not appear in
man, and that the hymen which is unique to
the genus Homo is absent in the anthropoids.
Several anatomists have followed Aristotle
in holding that the hand places man in a
distinct order, while Topinard was equally
emphatic regarding the human foot. Ev-
idences along these lines are supplemented
by pre-historic archeology, as all the older
human crania are dolichocephalic, while the
crania of all anthropoids are extremely
brachycephalie.
Whether “ scientists ” are entitled to believe
what they please or are to be guided by ob-
servations and verifications is perhaps an open
question. Weismann accepted generatio
aequivoca, although he admitted “all the
evidence is against it.” Still, many of us
believe that a sound science and a sound ed-
ucation demand fidelity to the facts of expe-
rience and to those theories alone which grow
out of them. Mattoon M. Curtis

A GIRDLING OF BEAN STEMS CAUSED BY.
BACT. PHASEOLI
Durine a field trip in Michigan in July,
1914, the writer found a peculiar girdling of
the stems and branches of field beans to be
prevalent in several localities. Specimens
were collected from Kent, Newaygo and Tus-
cola counties. Since then specimens of this
disease have been collected from various
parts of the state each year.
The disease appears at the nodes of stems
and branches as small water-soaked spots.
These enlarge, encircling the affected parts.
Later these diseased areas become amber-
colored. This girdling is usually completed
by the time the pods are about half mature.
‘The affected tissue is so weakened that from
the weight of the tops the stem breaks at the
diseased node. These signs of the disease
may appear before any evidence of the bac-
terial blight upon the pods.
JULY 27, 1917]
Inoculations into stem nodes of healthy
plants, with a pure culture of Bact. phaseoli
Erw. Sm. have produced typical signs of the
disease. Plants so inoculated also showed the
characteristic breaking at the stem node.
Plants inoculated in a similar manner with
cultures of species of Fusarium and Rhizoc-
tonia isolated from platings of this diseased
stem tissue, showed no girdling or breaking.
It seems likely that infection results from
the washing of bacteria from affected coty-
ledons or leaves to the axils of the leaves, but
the method of entry of this organism is not
yet worked out.
A more complete report upon this disease
will be given at a later date.

to say our utter poverty, in all three depart-
ments of chemical manufacture.
In the course of the articles, which have
been written by men eminent in their re-
spective fields of chemical science and its ap-
plications, the distinction is made absolutely
clear as between industries the development
of which has mainly been the result of the
SCIENCE 89
adoption of steam power and of mechanical
appliances, and those depending upon funda-
mental researches of a physical and chemical
character, such as are, to use the phrase of one
of the writers, “built up from the depths,”
and require, therefore, not merely the ener-
getic business organizer and “ scientific man-
agement,” with a view to output, but the
highly trained scientific man capable of ap-
preciating the discoveries of pure science and
apt in their application to human needs. In
this valuable review of the progress of the
many departments of a vital industry—the
key, indeed, to the successful prosecution of
many allied and dependent industries—it is
clearly revealed how remiss the nation has
been in a true appreciation of what con-
stitutes the firm foundation of industrial pre-
eminence. The fault has lain not so much,
as some of the writers seem to indicate, with
the colleges and universities as with the indus-
tries concerned, which have hitherto offered
small salaries and poor prospects to the care-
fully trained and competent science student;
indeed, have looked upon the chemist as a
necessary evil, to be avoided if possible.
One of the most important articles is that
by Dr. Levinstein, inasmuch as he carefully
points out the. respective spheres of the uni-
versity and the works in the effective train-
ing of the future industrial chemist. Once
those concerned with the successful adminis-
tration of our industries realize the necessity
for encouraging by a liberal payment the work
of the efficiently trained chemist there will be
no lack in the supply of suitable men. That
the nation contains such men has been shown
by the fact that the demands of this devastat-
ing war for the supply of high explosives have
been met with an energy and an efficiency
which have surprised our chief enemy.—

SCIENTIFIC BOOKS
The Theory of Measurements. By Lucius
Turtie, B.A., M.D., Philadelphia, Dr. Lu-
cius Tuttle, Jefferson Medical College.
1916. Pp. xiv-++ 303. Price $1.25.
Any one who has read the reports on elemen-
90 SCIENCE
tary laboratory work in physics presented by
average students must have been impressed
frequently by the writer’s lack of familiarity
with ordinary methods of computation and by
his inability to draw rational conclusions re-
grading the accuracy and significance of his
results. Unfortunately, the instruction in these
matters presented by many widely used labora-
tory manuals is very inadequate and frequently
misleading. We all admit that the primary
object of elementary laboratory work is to put
the student in personal touch with the facts
and principles of physical science. But every
experienced teacher knows that this object is
not attainable without more or less formal
instruction in the methods of reduction and
interpretation of observations. Moreover, the
student is seriously handicapped by the long-
hand arithmetical processes taught in second-
ary schools when greater precision and facility
can be attained by the shortened methods of
computation adopted by every competent phys-
icist.
A number of books designed to fill this gap
by a detailed discussion of methods of com-
putation and the theory of errors have ap-
peared during the past few years. Dr. Tuttle’s
“Theory of Measurements” belongs in this
group and it meets the needs of students in
elementary physics more adequately than any
other text that has come to the reviewer’s
attention. For the most part, concrete ex-
amples are developed to illustrate general prin-
ciples and the discussions are so clear and well
stated that the student can hardly fail to grasp
‘ their significance. The treatment presupposes
no training in mathematics. beyond that
usually required for admission to college. In
fact capable high-school pupils should find
little difficulty in following the discussions.
The most important topics treated in the
first one hundred pages of the book are as
follows: fundamental ideas, abridged methods
of multiplication and division, units and meas-
urements, angles and circular functions, ac-
curacy and the correct use of significant fig-
ures, logarithms, computations involving small
magnitudes, and the use of the slide rule. The
reviewer would be inclined to place more
[N. S. Vou. XLVI. No. 1178
emphasis on the importance of systematic
orderliness in computation and exact specifi-
cation of units in writing numerical results.
But on the whole the treatment is very good
and guards against most of the common
errors of inexperienced computers.
About seventy pages are devoted to a very —
illuminating discussion of the methods of
graphical representation and reduction of ob-
servations, including a brief treatment of in-
terpolation and extrapolation. The possibil-
ity of emphasizing the significance of the
plotted data by a suitable choice of scales is
illustrated by numerical examples and. the
advantages of so choosing the variables that
the graph will be linear are pointed out.. The
uses of logarithmic and _ semi-logarithmic
papers are also illustrated. 4
The remaining portion of the book deals
with errors of observation and measurement,
statistical methods, the determination of the
best representative value from a series of dis-
cordant observations, the estimation of the
precision of direct and indirect measurements,
and simple applications of the method of least
squares. The formule of the theory of errors
are not derived mathematically but their sig-
nificance and use are very clearly explained
and illustrated by numerical examples.
The book is neatly printed and substantially
bound. It should find a place in every phys-
ical laboratory devoted to the: instruction of
students.

LITHOLOGIC EVIDENCE OF CLIMATIC
‘PULSATIONS ~
Tue geologic evidences of changes of cli-
maté, as is well known, are numerous and
incontrovertible, particularly as regards ex-
tremes of temperature and their accompany-
ing variations of flora and fauna. The cli-
matic changes which have produced the most
widespread changes in life forms, as well as
physiographic features, have been the ones
most clearly recognized and easily studied.
These changes are known to have been pulsa-
tory or periodic, but with periods or cycles
JuLY 27, 1917]
enduring for possibly many thousands of
years.
In modern times, and in very recent geo-
logic times as well, there have been minor fluc-
tuations or pulsations in climate in various
parts of the earth, as ably demonstrated by
Briickner, Huntington and others. The
“ Briickner cycle,’ about thirty-five years in
length, illustrates one type of pulsation.
Hann, Melldrum, Douglass, and others have
observed an eleven-year period to be about the
average length of time between the maxima
of wet or dry conditions. While the length
of the cycles or periods may vary, the com-
binations of these shorter cycles of climatic
changes are considered as making up the
grand or climatic eycles, which are the ones
best known in geology.
If the pulsatory theory of climatic change
is a true interpretation of the observed facts
of recent times, as seems very probable, then
one may naturally inquire if similar pulsa-
tions or minor changes in climate have not
occurred in the geologic past. If they have,
what evidence, if any, is to be found in the
rocks? The work of Barrell, Sayles, Case
and others, in their studies of sedimentation,
seems to definitely correlate climatic fluctua-
tions with various phases of erosion and
deposition. It may be of interest to submit
some facts which may prove to be additional
evidence of climatic pulsations, as afforded
by certain “sedimentary ” rocks.
The writer, in the course of a study of the
sandstone formatioris in the foothills south-
west of Fort Collins, in northern: Colorado,
came to the conclusion that much of this
sandstone is of subaerial, anid not subaqueous,
origin. The sandstones of this region are
commonly referred to as “ Red Beds.” The
stratigraphic names are the Lyons, and the
Lykins formations.
In the most prominent ridge of the Lykins
outcrop are located a number of quarries from
which flagging and building stone have been
taken for many years. One prominent
feature of much of this stone is its variegated
laminations. These are usually alternate
layers of white: and brown sands, although
SCIENCE 91
other colors are occasionally found. These
layers vary in thickness from about 0.5 mm.
to 30 or 40 mm. In a number of eases the °
white layers are much thicker than the brown,
while in many other cases the two kinds of
layers are nearly equal in thickness. Also,
the brown layers are often thicker than the
white. Very thin alternate layers often
occur, and there are usually many of these in
a group when they do occur.
Examination of the character of typical
samples from these layers shows, essentially,
the following facts:
1. The white layers are composed almost
“wholly of very well rounded grains of white
quartz, with scattered specks of iron oxide;
the quartz grains are nearly uniform in size,
the largest being rarely over 1 mm. in di-
ameter, and the smallest about 0.8 mm. in
diameter; the white layers are almost wholly
free of any colored cement, and of angular or
even subangular grains; many of the grains
are pitted; wind ripples are frequently found
at the top of a white layer, on exposed bedding
planes.
2. The brown layers are composed almost
wholly of angular and subangular grains of
many different sizes, from very small to over
1 mm. in diameter; comparatively few rounded
grains are present; the color is due to a coat-
ing of iron oxide on most of the grains.
These differently colored layers of sand,
having such markedly different character-
istics, would seem to point clearly to rather
different origins. The factors and forces con-
tributing to their formation can hardly be
said to be identical. The material of the’
white layers suggests rounding, pitting, sort-
ing, and deposition by the wind. The ma-
terial of the brown layers has evidently been
water-worn and water-borne, coming from a
comparatively distant -region. The occur-
rence of these different layers with their im-
plied differences in origin and deposition may
well suggest something of the history of this
region, especially in regard to the extent and
frequency of rainfall.
As these rocks contain no fossils, and in
their general lithological character point to
92 SCIENCE
deposition by the wind, one may at least ten-
tatively conclude that the climate of this
region was rather arid at the time the sands
composing these rocks were put in place by
the forces of nature. This part of the con-
tinent was evidently a portion of the great
inland desert which is thought to have existed
in Triassic times.
It seems probable that at one season this
particular locality was swept by winds carry-
ing a burden of well-worn quartz grains,
which was dropped when the force of the
wind was checked. When the wind rose
again, some of this sand was doubtless moved
farther on, but a little remained to add to the
accumulating layers beneath. At another
season, the surface of this wind-laid sand was
covered by a deposit of entirely different ma-
terial, probably brought from some neighbor-
ing zone of alluviation by torrential rains.
When the water had flowed on, or evaporated,
the red-brown material became exposed to the
winds, part of it was doubtless swept away,
but some was covered with desert sand which
continued to accumulate until the next
freshet sent more of the red-brown sediment
into the depression in the zone of dunes.
That this was approximately the mode of
deposition seems likely, when we find the one
layer to be characteristically wind-borne, and
the other water-borne, when all the accom-
panying facts are considered, and comparison
[N. 8. Vou. XLVI. No. 1178
is made with sand deposits that are being
formed at the present time.
The study of this sandstone takes on an
added interest if we note further that the
frequency of recurrence of the brown or white
layers often shows a striking regularity or
periodicity. Where we find fairly broad
white bands, with very thin brown layers
alternating, it would seem that a relatively
dry season is indicated. On the other hand,
when the brown layers are very numerous and
close together, it apparently points to fre-
quent rains, with comparatively little deposi-
tion of the white sands by the wind. In the
solid rock wall, as observed in the quarries,
one can note the more or less regular recur-
rence of the wider bands of white, and if one
could be sure that here a wide white band
and one or more narrow brown bands repre-
sented the deposit of an arid year, one could
determine the time required to produce a
given thickness of this rock and also draw
some conclusion as to the relative aridity of
a given year or a series of years. But one
can not at present state, beyond reasonable
limits, the amounts of either kind of material
that might be deposited in a year, and there-
fore one may not yet say definitely how long
it took for a given stratum to be formed, or
whether the aridity indicated by a white band
corresponds to one ‘season or to several. It
may be interesting to note, however, that the
recurrence of groups of brown layers with a

corresponding decrease in thickness of the
white layers is found, on the average, follow-
ing every tenth or eleventh layer.
This recurrence, as observed at a number
of places on the quarry walls, as well as on
detached fragments, ranges from the sixth to
the fifteenth white layer. For example, at
one place (Quarry “A,’ Section I.) the
writer measured the thickness of the series of
white layers, the thickest layers recurring as
follows: seventh, eleventh (from and includ-
ing the seventh), fifth (or fifteenth from the
seventh), eleventh, ninth, fourteenth. At
Section II., Quarry “A,” the thickest white
layers recur as follows: ninth, seventh, sixth.

wise, from the top of column 2 to the top of
column 6 there are 40 white layers; from the
top of column 6 to the top of column 10 there
are 38 white layers.
It may be that it is just by chance that
these layers are arranged in this way, yet the
agreement with known climatic pulsations is
so striking as to make one ask whether it is

At another place (Quarry “B”), about a
quarter of a mile away, the following periods
were observed: tenth, twelfth, tenth, seventh,
eleventh, fifteenth, tenth, twelfth, sixth, thir-
teenth, sixth. These three sections are about
2.5, 2 and 4 feet in thickness, respectively.
The details of these measurements are shown
in the tables above. On about 18 quarried
fragments it was found that on the average
every eighth to twelfth white layer was thicker
than those between. On several such frag-
ments, this recurrence was observed as fol-
lows: eleventh; tenth; eleventh and following
ninth; eighth; ninth and following eleventh;
tenth.
Another striking periodicity may be noticed
in the tables. These periods correspond
rather well to the average number of years in
the Briickner cycle, as from the top of column
just chance after all, or a result of natural
laws. It is quite evident that the recurrence
of layers of a certain character is periodic.
Whether one can in this manner safely assign
a limit to the yearly deposits seems question-
able, but one may certainly inquire into the
probability of deducing from a study of these
variegated sandstones the conclusion that at
the time of their formation the climatic con-
ditions, especially with reference to rainfall,
were fluctuating much as they have been
within recent times.
It would be distinctly interesting to know
whether geologists can find, in more exact and
complete studies, further evidence of pulsa-
tory changes of climate haying been recorded
in the clastic rocks. C. E. Vai

KANSAS CITY MEETING OF THE AMER-
ICAN CHEMICAL SOCIETY
THE fifty-fourth meeting of the American Chem-
ical Society was held at Hotel Muehleback, Kan-
sas City, Kansas, from April 10 to April 14, 1917.
The general program was carried out under the
able leadership of Professor Julius Stieglitz, presi-
dent of the society, and Dr. Charles L. Parsons,
secretary, while the various divisions were pre-
sided over by Charles L. Alsberg, E. H. S. Bailey,
J. E. Breckinridge, J. R. Bailey, H. E. Howe, H. P.
Talbot, L. F. Kebler and T. J. Bryan.
During the session the usual order of business
was carried out, consisting of meetings of the
council, inspection of plants, with general and pub-
lic sessions. A complimentary smoker and sub-
scription banquet added to the diversion of the
week. i
On Wednesday morning, April 11, addresses of
welcome were given by Hon. George H. Edwards,
mayor of Kansas City, and by Dr. Frank Strong,
chancellor of the University of Kansas. Response
to these addresses was made by President Julius
Stieglitz. Mr. Arthur J. Boynton gave a very in-
teresting paper on the Economic resources of the
Kansas City zone.
Wednesday afternoon was given over to a pub-
lic session, of which the program was as follows:

The toxicity of galactose and mannose for
green plants and the antagonistic action of other
sugars toward these: LrEwis KNupson. The
toxicity of galactose to the growth of Pisum
arvense L. and to Triticum sativum L. was in-
hibited by glucose or saccharose, the former be-
ing slightly more effective than the latter. But
levulose, arabinose, maltose and raffinose do not
inhibit the toxicity of galactose, although in pres-
ence of levulose the primary root may continue its
growth to a limited extent It was found that
0.0125 mol. galactose was as toxic as 0.025 mol, the
other sugars being used at a concentration of 0.025.
Mannose had a toxie effect similar to galactose.
Glucose or saccharose inhibited the toxicity of
mannose,
The effect of three annual applications of boron
on wheat: F. C. Cook and J. B. Wiuson. Borax
and colemanite were applied to horse manure in
amounts sufficient to act as a fly larvicide. The
manure was applied to the same plats at the rate
of 20 tons per acre for three consecutive years and
wheat was grown on the plats each year at Arling-
ton, Va. A borax, a colemanite, a manured control
and an unmanured control plat were used. It is
calculated that the upper 6 inches of soil of the
borax plat received .0088 per cent. H,BO; the first
year and .0022 per cent. the second and third
years. The colemanite plat likewise received .0029
per cent. H,;BO;. Borax reduced the yield of
grain 10 per cent. in 1914 and 1915, colemanite had
little effect. In 1916 the yields from all four plats
were low, but the borax plat gave the largest yield.
The only apparent injury to the wheat was the
first season on the plat receiving the large amount
of borax. There were no evidences of any cumu-
lative action of boron in the soil.
The after-ripening of fruits: EF. W. Munciz and
W. P. JAMES, Illinois Agricultural Experiment Sta-
tion, Department of Horticulture. Attempts to
preserve peaches by encasing with hard paraffin
were unsuccessful, since considerable decomposi-
tion resulted after two months, with a marked pro-
duction of alcohol and an intensely bitter taste.
The color, however, remained normal, and the
skeleton of the fruit was not broken down. This
last condition is similar to that described for other
fruits kept in an atmosphere of CO, by other work-
ers and is apparently due to an accumulation of
carbon dioxide within and about the fruit.
JULY 27, 1917]
Peaches decomposed rapidly about the spot where
an injection of invertase had been made, or in a
solution of invertase. Similar experiments are in
progress with apples, in an effort to explain the
discrepaney between the decrease in sucrose con-
tent of apples during ripening found by Bigelow,
Gore and Howard and the absence of invertase
from the apples studied by Thatcher. Flesh and
epidermis of peaches kept in an atmosphere of O,
for two months became golden yellow, but turned
brown quickly on exposure to air. The flesh was
soft, contained a little alcohol, and had an insipid
taste. Quantitative study of the respiration of
apples in an atmosphere of oxygen, showed that
the rate is higher under this condition than in an
atmosphere of air.
Quantitative determination of carbohydrates in
plant tissues: F. W. Munoiz and D. T. ENGLIs.
If fresh plant tissue is plunged into warm alcohol
and after standing two weeks, the aleohol removed
by decantation and expression before extraction
with hot alcohol, a large percentage of the sugar
(96 per cent. in one experiment) is removed and
loss of fructose by hot extraction largely avoided.
Mercurie nitrate is more satisfactory to use than
the acetate and 10 per cent. phosphotungstic acid
than the more concentrated solution used by them.
Asparagin also is quantitatively removed from so-
lution by mercuric nitrate provided the solution is
made just alkaline to litmus with sodium hydrox-
ide or carbonate after addition of the mercuric
salt, then just acid with a few drops of weak acid.
No mereurie oxide is precipitated by such a pro-
cedure. These reagents, especially the phospho-
tungstie acid, invert sucrose so quickly that they
are not applicable to the determination of a mix-
ture of sucrose, glucose and fructose, excepting
when sucrose has been previously determined. This
may be done by using basic lead acetate as the
clearing agent, by the polarimetric method if the
inversion is made with invertase or solution again
made neutral after use of acid. When the value
for sucrose is known, the original solution par-
tially cleared with SO,-free alumina cream is in-
verted with invertase, then nitrogenous impurities
removed with mercurie nitrate and phosphotungstic
acid and total glucose and fructose determined.
Subtraction of value for sucrose leaves the values
for glucose and fructose present in the original
solution.
A physical and chemical study of the kafir ker-
nel: GEORGE L. BIDWELL. Dwarf, black-hulled,
white kafir kernels were separated by hand into
bran, germ and endosperm. These parts were
SCIENCE 95
analyzed and compared to corresponding parts of
corn and were found to resemble them closely. In
the bran a wax-like substance was found. The
ether extract of the germ was found to be liquid.
The endosperm yielded an ether extract not yet
examined. The coloring matter in this sample
does not seem to be associated with tannin. The
endosperm may be separated into starchy and
horny parts, the former having less protein than
the latter.
Oil from the avocado: H. 8. Bamry and L. B.
Burnett. The production of the avocado or alli-
gator pear in the United States is increasing so
rapidly that there is a possibility of large quanti-
ties of this fruit being available as a source of oil.
The fruit when fully ripe contains approximately
80 per cent. of moisture and the dried material
about 50 per cent. of oil. So far no method has
been found by which the oil can be extracted from
the fruit in a sweet, edible condition, and as the
oil when extracted with ether and the solvent re-
moved at low temperature in vacuum has a bitter
taste, it is very doubtful whether the oil as it ex-
ists in the fresh fruit itself is palatable if sepa-
rated from the accompanying pulp. By means of
the usual hydrogenation process it is compara-
tively easy to convert either the expressed oil or
that extracted by solvents into a solid, white,
tasteless, fat which resembles in its physical prop-
erties ordinary hydrogenated cottonseed oil.
Oil from the Stillingia sebefera: H. S. BamEy
and L. B. Burnerr. The fruit of the semi-trop-
jeal tree Stillingia sebefera, which grows in China
and has been introduced into some of the southern
states of this country, produces two glycerides.
The exterior of the seed is covered with a wax-like
substance from which is derived the Chinese
vegetable tallow of commerce. The interior of the
seed contains an oil usually known as stillingia oil.
Certain statements in the literature indicate that
this oil even in China is not used for food purposes
and probably has poisonous properties. The con-
stants of these oils have been determined, and ex-
periments made by Dr. William Salant, of the Bu-
reau of Chemistry, in feeding rabbits with both
the expressed and extracted oils, So far as the
results obtained with the small amount of ma-
terial available are conclusive, it appears that
stillingia oil is not toxie and has practically the
same effect as other vegetable oils.
A noteworthy effect of bromides upon the action
of malt amylase: ArTHUR W. THomasS. The ac-
tion of sodium and potassium bromide upon malt
amylase was found_to be inhibitory when present
96
in small amounts, but when these salts were pres-
ent in greater concentration an activating action
was obtained. This action was found when highly
purified Lintner soluble starch and thrice repuri-
fied bromides were used.
Availability of the energy of food for growth:
C. Rosert Mouton, Missouri Agricultural Experi-
ment Station. Three beef steers were subjected to
digestion trials and maintenance trials. One was
slaughtered as a check. The other two were fat-
tened, one to full prime condition and the other to
forty or fifty days under prime. All were analyzed.
From the analysis the composition of the animals
was determined and the composition of the gain.
From the feed records and analyses the nutrients
consumed above maintenance were determined.
The energy equivalent of the flesh gained and of
the feed consumed above maintenance was caleu-
lated. The two fattened steers saved in flesh
gained 53.39 and 52.49 per cent. of the metabo-
lizable energy consumed aboye maintenance. For
similar conditions and a similar ration Armsby
shows about 55 per cent. availability. This is an
experimental verification of his calorimetric work.
Investigation of the Kjeldahl method for de-
termining nitrogen; the influence of reagents and
apparatus on accuracy: I. K. PHELps and H. W.
Daupt. As a result of many experiments the con-
clusion was reached that in all routine work in-
volving determinations by the Kjeldahl method it
is necessary to deduct from the result obtained
the amount corresponding to the nitrogen con-
tributed by reagents and apparatus in use in the
particular experiments. It is obvious that under
less carefully controlled conditions in routine work
the errors, which are here called inappreciable, will
become large enough to seriously effect the accu-
racy of the results obtained.
A study of the estimation of fat in condensed
milk and milk powder: C. H. BIESTERFELD and O. L.
Evenson. The Roese-Gottlieb method as applied

sults, the average error in the case of condensed
milk being 0.04 per cent. The residual fat is ob-
tained by treating the liquid left after three ex-
tractions by the Roese-Gottlieb procedure with

ticularly under pathological conditions. The
method is based on the production of CO when the
ether extract of urine is treated with H.SO,.
Hippuric acid is present in the ether extract and
does yield- CO. Other substances yielding CO,
such as oxalic and citric acid, do not enter the
ether extract by this method. Citric acid is pres-
ent in normal urine. The method is of unques-
tionable value in indicating the excretion of sub-
stances under pathological conditions which belong
to a group of substances capable of yielding CO
under the conditions of the experiment.
On the optimum reaction for tryptic proteolysis:
J. H. Lone and Mary Huu. It has generally
been assumed that tryptic digestion is possible in
a neutral or slightly alkaline medium only, but
some recent investigations suggest that these lim-
its are too narrow. Employing fibrin as a sub-
strate, the authors have found the optimum point
at a hydrogen ion concentration between 10-8 and
5 X 10-9, which is in agreement with the results of
Michaelis and Davidsohn for a fibrin peptone sub-
strate. The authors have found, however, that for
casein as a substrate the optimum point is dis-
tinetly higher, and within the limits 3 x 10-6 and
5 x 10-7. It is probable that for each type of
protein there is a distinct range for the optimum
activity and that casein may not be the only pro-
tein which is changed readily on the acid side of.
neutrality. Investigations on other proteins are
in progress.
On the normal reaction of the intestinal tract:
J. H. Lone and FREDERICK FENGER. Employing
the electrometric method of estimation the au-
thors have studied the reaction of the small intes-
tines of a number of animals and also of man.
Misled by the false interpretation of the results of
indicator tests certain writers have reached wrong
conclusions regarding the normal or usual reac-
tion between the pylorus and the lower end of the
ileum. In the case of animals the whole intestine
has been removed immediately after death, tied
into three loops and each loop investigated sepa-
rately. In some eases the reaction has been found
to be acid throughout and from 1 to 3 xX 10-7.
Alkaline reaction seems to be less common than
acid, and far from the strength once assumed for
the duodenum with its alkaline ‘‘zone.’’ In the
human subject material has been secured from
points well below the duodenum by aid of Rehfuss
tubes. An acid reaction is frequently noted here
and persisting more frequently than the tempo-
rary alkalinity following the entrance of bile and
the pancreatic fluids

Studies of the gastric residuum. No. III. The
relation of total phosphorus to acidity: CHESTER
C. Fow er, Iowa State College. In view of re-
cent support of a modification of Maley’s hypothe-
sis concerning gastrie hydrochlorie acid formation
and a suggestion of approximate proportionality
which might be expected to occur between the
acidity of the juice and its acid calcium phos-
phate, it seemed desirable to study phosphorus and
phosphorus partition of the gastric residuum.
Thus fifty-two samples from apparently normal
women were obtained and individually analyzed
for total phosphorus. The conclusions follow:
(1) Total phosphorus was not proportional to total
or free acidity. (2) The minimum P.O, content
was 6.48 mgr. per 100 e.c. and the maximum was
30.03 mgr. (3) About 58 per cent. of the samples
fell within the range P.O, equivalent to 12-18
mgr., while about 21 per cent. lie above and 21
per cent. below these values. (4) A tendency
toward a constant P.O, content was shown in in-
dividuals who were examined more than once.
(5) The average P.O, content was 15.66 mgr. In
a previous investigation made upon a composite
residuum sample obtained from seventy men, a
value of 12.16 mgr of P.O, per 100 e.c. of re-
siduum was obtained.
The utilization of carbohydrate on a relatively
high and low cereal dict: ZELMA ZENTMIRE and
CHESTER C. FowLer. The object of the study was
to determine any differences in the utilization of
cereal protein and carbohydrate in thoroughly
cooked eream of wheat when ingested in varying
amounts. The data on protein utilization will be
presented in a later paper. The experiment was
divided into two periods of five days each with
relatively high and low amounts of cereal in the
diet; and two periods of two days each of nitrogen-
free diet of relatively low and high starch con-
tent. Casein and milk were added to the cereal
diets and butter fat and sucrose to all diets.
Foods and feces were weighed and analyzed. The
total carbohydrate utilization for each of the four
periods was over 99 per cent. If the utilization of
sucrose and milk sugar is taken as 100 per cent.,
the utilization of the starch and cereal carbohy-
drate is about 98 per cent.
The nature of the inosite phosphoric acids of
some important feeding materials: J. B. RATHER,
Arkansas Agricultural Experiment Station. An
inosite phosphoric acid has been separated from
wheat bran corresponding in composition to the
formula C,.H,,0..P,, the formula previously pro-
posed for this substance by the writer. It corre-
SCIENCE
97
sponds equally as well to the formula
C,H,(OH) (H.PO,).,
inosite pentaphosphorie acid. The latter formula,
almost exactly one half of the first formula, and
that of a theoretically possible compound is
adopted as the more desirable. The principal ino-
site phosphoric acid of a sample of corn was found
to be inosite pentaphosphorie acid, and neither ino-
site hexaphosphorie acid, nor the acid C,H,P.O,.
The principal organic phosphoric acid of a sample
of kafir corn was found to be inosite pentaphos-
phorie acid.
The formation of ester hydrolyzing substances
by the action of alkali on casein: FLORENCE HUL-
TON FRANKEL. Harriman Research Laboratory,
Roosevelt Hospital, New York. The action of
alkali on casein causes the formation of ester
hydrolyzing substances, the formation of which is
practically independent of the concentration of
alkali, time of standing and temperature of stand-
ing. The substance is more active in very slightly
alkaline solution (10-8-10-1°) and loses a part of
its activity on boiling. It can be entirely removed
by long dialyzing. The action was tried on vari-
ous esters.
Factors influencing the proteolytic activity of
papain: EpwarpD M. FRANKEL. Papain may be
purified by precipitation from aqueous solution
with acetone or ethyl alcohol. The ferment is in-
activated by acids and alkalis in concentrations
from 0.02 normal upwards. The enzyme is active
between hydrogen ion concentrations 10-2 and
10-9, the optimum being at 10-5, calorimetric
standards being used throughout. The quantita-
tive relations of the enzyme and substrate have a
marked effect on the extent of proteolysis, inereas-
ing quantities of either component causing an in-
crease up to a certain point after which further
additions have little effect. In the presence of
HCN the proteolytic activity of papain is largely
inereased the same general relations between
enzyme and substrate holding. Inereasing the
amount of HCN causes increased proteolysis up to
a certain point, after which further addition caused
no marked change. The same hydrogen ion opti-
mum holds for papain in the presence of HCN as in
its absence. HCN will cause further proteolysis in
enzyme substrate mixtures that are apparently in
equilibrium.
Variations in the chemical composition of alfalfa
at different stages of growth: H. 8. GrinpLEy and
H. C. Ecxstery. In connection with inyestiga-
tions which the Illinois Experiment Station is ma-
98 SCIENCE
king to determine the value of forage crops for the
growth of farm animals, it became necessary to
make complete chemical analyses of young grow-
ing grasses and legumes. The first young forage
crop to study was that of alfalfa. The work in-
cludes the determination of the approximate com-
position, the forms of non-protein nitrogen, and
the forms of protein nitrogen in the grasses and
legumes. The results so far obtained with alfalfa
lead in general to the following conclusions: First,
that young alfalfa is very rich in crude protein;
second, that as alfalfa grows older, there is a
marked increase in the percentage of nitrogen free
extract and crude fiber and a marked decrease in
the crude protein of the water-free substance of
the plant; third, it seems probable that the
marked efficiency of young growing pasture grasses
is due (a) to their high content of crude protein
(b) to their high content of mineral constituents
and (c) to the low content of crude fiber.
Physical and chemical constants of some Ameri-
can tomato seed oils: H. 8. BatuEy and L. B. Bur-
NneTT. A number of tomato-seed oils have been
made from seeds collected at various tomato pulp
factories in Indiana and Maryland and the phys-
ical and chemical constants of these oils and their
fatty acids determined. One point of particular
interest in connection with the tomato-seed oil is
that it gives a positive test for peanut oil by the
Renard test. If sufficient care, however, is taken
in determining the melting point of the final erys-
talline acids it will be found that they are higher
than 72° C., which is usually accepted as the
proper temperature for arachidie acid obtained in
this method. The analysis of the methyl esters of
tomato seed oil and of the saturated fatty acids ob-
tained by the lead-salt-ether method from tomato-
seed oil have been made.
A laboratory method for the hydrogenation of
oils: L. B. Burnett and H. S. Batnzy. A method
of preparing a nickel catalyzer, suitable for the
hardening of vegetable oils on a small scale in the
laboratory, was described.
Electrically heated melting point apparatus: H.
S. Barry. A form of melting point apparatus
heated by the passage of an electric current
through a bath of dilute sulphuric acid, was de-
scribed. The resistance of the solution to the
passage of the current produces the heat, the in-
crease in which may be regulated by adjustment
of the distance between the poles.
The alkaloids of Bocconia frutescens: EMERSON
R. MitiEr. In 1895 Battandier examined the bark
of Bocconia frutescens and reported the presence
[N. 8. Von. XLVI. No. 1178
of fumarine (protopine), bocconine, chelerythrine
and traces of an alkaloid giving reactions similar
to those of cheliodonine. Bocconine, according to
Schlotterbeck, is identical with @-homochelidonine.
The writer separated from the leaves of the above-
named plant protopine, chelerythrine, B-homocheli-
donine and y-homochelidonine. The indications
are that the bark contains sanguinarine in addi-
tion to the alkaloids reported by Battandier.
On the presence of free hydrocyanic acid in cas-
sava: EMERSON R. Miuurr. Some experiments
carried out by the writer while connected with the
Cuban Experiment Station show that most of the
hydrocyanie acid contained in the roots of Manihot
utilissima is present, combined as a eyanogenetic
glucoside.
The effect of feeding acids upon the growth of
swine: A. R. Lamp and JoHn M. Evvarp. Al-
though the power to use ammonia produced in the
body tissues for the neutralization of acids is
known to be possessed by animals, the practical
question of the effect of acid-feeding upon growth
has not been investigated. Inasmuch as silage
contains organic acids in considerable amount and
the mineral content of many feeding-stuffs is
strongly acid in character, this question is impor-
tant. Eight pigs, divided into 4 lots, were grown
successfully from 85 to 260 pounds weight in seven
months upon a normal ration to which consider-
able amounts of lactic, acetic and sulphuric acids
were added.
Can swelling of the colloids furnish a basis for
the explanation of edema? A. D. HIRSCHFELDER.
Edema due to mustard oil in the conjunctival tis-
sues, the effects of immersing the lid in blood
serum, hydrochloric acid, ete., effects of local and
general changes in blood pressure upon the de-
velopment of edema, were discussed.

THE WORK OF THE NATIONAL
RESEARCH COUNCIL
As has already been announced, the
National Research Council is acting as a
department of the Council of National De-
fense, dealing with the organization of
science and research as affected by the
war.
Direct connection with the work of the
Army and Navy, both at home and in the
field, has also been established. Brigadier
General George O. Squier, chief signal
officer, has recently addressed the follow-
ing letter to the chairman of the Research
Council:
Dr. GrorGE E. Hate,
Chairman, National Research Council,
Munsey Building,
Washington, D. C.
My dear Dr. Hale: In the Signal Corps ques-
tions involving the selection and organization of
large numbers of scientific men and the solution of
research problems are constantly arising. The Na-
tional Research Council, organized at the request
of the President, and acting as a department of the
Council of National Defense, in close cooperation
with similar bodies abroad, has federated and co-
ordinated the scientifie resources of the country
and concentrated them upon the solution of
military problems. It is accordingly the one
agency in a position to meet the present needs of
the Signal Corps.
I therefore request the Research Council to act
as the advisory agent of the Signal Corps in the
organization of its various scientific services and
the solution of research problems. To this end I
would suggest that Dr. Robert A. Millikan, vice-
chairman and executive officer of the Research
Council, apply for a major’s commission in the
Officers’ Reserve Corps, for detail in charge of this
work. Very truly yours,
GrorGE O. Squier,
Brigadier General,
July 2, 1917 C. S. O.
100
In accordance with this request Dr.
Millikan is now acting as the representa-
tive of the National Research Council in
general charge of scientific questions re-
ferred to the council. Dr. C. E. Menden-
hall has been put in charge of the develop-
ment of the various instruments used in
connection with airplanes. Dr. Augustus
Trowbridge, also nominated by the council,
has organized an important branch of the
scientific service for the army in France.
Other scientific services for the army are
in process of organization.
The Navy Department has recently
established a special board of four naval
officers and four civilian advisory mem-
bers to coordinate and organize all prob-
lems relating to submarine warfare. The
National Research Council is officially rep-
resented on this board by its executive
officers. The general plan adopted by the
Navy Department contemplates the closest
possible cooperation between the Navy
Department bureaus, Navy Department
boards, the Naval Consulting Board, and
the National Research Council. A group
of forty leading physicists, convened by
the National Research Council for an ex-
haustive discussion of submarine problems
with the members of the French Scientific
Mission, is now represented by a committee
cooperating with the above mentioned
special board in tests and investigations
of various devices for submarine offense
and defense. Many physical laboratories
are also taking part in this work.
The chairman of the council, Dr. George
E. Hale, has given his entire time to the
work in Washington, and the following
members of the council are residing there
as well:
Dr. Raymond Pearl, chairman of the agricultural
committee.
Dr. William H. Holmes, chairman of the anthro-
pology committee.

During the past month the above-men-
tioned members of the council have been
actively cooperating with the members of
the French scientific mission now in Wash-
ington, as a result of which it has been
possible to formulate various agencies for
the consideration of technical problems for
the solution of which definite need has
arisen at the battle front. The members
of this mission have recently been joined
by Dr. Giorgio Abetti of the Royal As-
tronomical Observatory of Rome, sent as a
representative of the Italian Government.
Furthermore, most of the members of
the foreign service committee of the coun-
cil, who have been in France and England
for a period of two or three months, have
returned to the United States and have
brought with them much valuable informa-
toin relative to the organization and de-
velopment of scientific activities in con-
nection with the war. A few members of
the committee have remained in France
to continue their observations and investi-
gations, under special detail. Formal re-
ports have been submitted to the council,
through its executive and military com-
AucustT 3, 1917]
mittees, relating to the observations and
experiences of the members of this com-
mittee, in connection with which recom-
mendations for cooperative investigations
in this country are made.
The special committees of the council
on the subjects of optical glass and noxious
gases have submitted reports, which in turn
have been transmitted by the executive
committee of the council to the General
Munitions Board and the Council of
National Defense. As a result, arrange-
ments have been made for providing the
government with optical glass through co-
operation between the Bureau of Stan-
dards, the geophysical laboratory of the
Carnegie Institution of Washington, the
Bausch & Lomb Optical Company, and the
Pittsburgh Plate Glass Company. Re-
searches on noxious gases have been placed
under the charge of the director of the
Bureau of Mines, acting in cooperation
with the army and navy and the com-
mittee on noxious gases of the National
Research Council.
It is expected that announcement may
be made at a later date relative to prob-
lems initiated by the various committees
of the council and means for their solu-
tion.
A number of friends have generously
contributed to provide funds for the ex-
penses of the council. It is also a pleasure
to announce that at a recent meeting of
the Carnegie Corporation of New York,
the following resolution was passed:
Resolved, That the sum of fifty thousand dollars
($50,000) or so much thereof as may be necessary,

PSYCHOLOGY AND NATIONAL
SERVICE
Amone the many scientific problems which
the war has forced upon the attention of our
military authorities there are several which
are either psychological or present a psycho-
logical aspect. In the opinion of experts many
of these problems are immediately soluble
and it therefore becomes the duty of profes-
sional psychologists to render national service
by working on such problems. For this rea-
son a committee on psychology has been or-
ganized, with the approval of the council of
the American Psychological Association, by
the National Research Council. This com-
mittee consists of J. McKeen Cattell, G. Stan-
ley Hall and E. L. Thorndike from the Na-
tional Academy of Sciences; Raymond Dodge,
S. I. Franz and G. M. Whipple from the
American Psychological Association, and C.
E. Seashore, J. B. Watson and R. M. Yerkes,
chairman and member of the National Re-
search Council, from the American Associa-
tion for the Advancement of Science.
At the first meeting of the committee, it
was voted “that whereas psychologists in com-
mon with other men of science may be able
to do invaluable work for national service and
in the conduct of the war, it is recommended
by this committee that psychologists volunteer
for and be assigned to the work in which their
service will be of the greatest use to the nation.
In the case of students of psychology, this
may involve the completion of the studies on
which they are engaged.”
It is the function of this general committee
to organize and, in a general way, supervise
psychological research and service in the pres-
ent emergency. Problems suggested by mili-
tary officers or by psychological experts are
referred by the committee to appropriate. in-
dividuals or institutions for immediate atten-
tion. Already at the suggestion of the council
of the American Psychological Association
the chief psychological laboratories of the
country have been offered to the committee
for such use as the military situation dictates.
Moreover, the membership of the American
Psychological Association, in response to a
102
letter addressed to it by the council, has re-
sponded most promptly and heartily with
offers of personal service.
At a meeting held in Philadelphia, April 21,
the council of the American Psychological
Association, in addition to approving and
urging the appointment of a committee on
psychology for the National Research Council,
authorized the organization of twelve commit-
tees to deal with various important aspects of
the relations of psychology to the war.
The list of committees with their personnel,
so far as at present announced, follows, to-
gether with brief comment on the status of
their work:
COMMITTEES
Committee on psychological literature re-
lating to military affairs. It is the function
of this committee to prepare bibliographies
and abstracts of important psychological mil-
itary contributions for the immediate use of
committees, individual investigators and for
publication. Chairman, Madison Bentley,
University of Illinois.
Dr. Bentley already has rendered valuable
service to several of the committees.
Committee on the psychological examining
of recruits. The first task of this committee
is the preparation and standardization of
methods and the demonstration of their serv-
iceableness. Chairman, Robert M. Yerkes,
Harvard University, W. V. Bingham, Henry
H. Goddard, Thomas H. Haines, Lewis M. Ter-
man, F. L. Wells, G. M. Whipple.
This committee has prepared a method of
group examining, and also varied methods of
individual examining. The work, covering a
period of four weeks, was generously financed
by the Committee on Provision for the Feeble-
minded. The methods are now (July 25)
being tested in three army camps and one
naval station. The expense of this initial
trial, which is made primarily for the further
development and perfecting of the methods,
is met by an appropriation of twenty-five
hundred dollars made by the Committee on
Furnishing Hospital Units for Nervous and
Mental Disorders to the United States govern-
ment. At the present writing, the surgeon
general of the Army awaits lists of psychol-
SCIENCE
[N. 8. Von. XLVI. No. 1179
ogists who are both adequately prepared and
willing to serve as psychological examiners.
It is the conviction of the committee that
the psychological examiner, by applying
specially prepared and adapted methods to
recruits in the camps, should obtain measure-
ments valuable alike to line officers, to gen-
eral medical officers, and to the special officers
in charge of the psychiatric hospital units.
It is assumed that the work of psychologists,
although not strictly medical in character, but
instead vocational, educational and social,
will supplement that of the medical examiner
by supplying him with information otherwise
not available. Further, the psychologist may
aid the psychiatrist by detecting and referring
to him those individuals for whom careful
psychiatric examination is obviously desirable.
Committee on the selection of men for
tasks requiring special skill. This includes
the selection and promotion of officers, as well
as choice of men for varied. kinds of skilled
service. Chairman, Edward L. Thorndike,
Columbia University, J. C. Chapman, T. L.
Kelley, W. D. Scott.
A method of selecting officers devised by
Dr. Scott is now in use in many of the
Officers Training Camps.
Committee on psychological oleae of
aviation, including examination of aviation
recruits. Chairman, H. E. Burtt, Harvard
University, W. R. Miles, L. T. Troland.
Work looking toward the development and
thorough testing of methods for the selection
of aviation recruits has been authorized by
the Government and already is in progress in
at least one of the institutions where the re-
eruits are being trained.
Committee on the psychological problems
of incapacity, especially those of shock, re-
education and vocational training. Chair-
man, S. I. Franz, Government Hospital for
the Insane, K. 8. Lashley, J. B. Watson.
The task proposed for this committee is a
large and difficult one and the chairman plans
to organize, in intimate relations with various
military activities and agencies, a committee
which shall be competent to deal with the
varied scientific problems of incapacity.
Dr. Franz has himself developed methods for _
Aveust 3, 1917]
the reeducation of certain paralytics, and ac-
cording to our information his methods are
now used by the Military Hospitals Com-
mission of Canada. It is greatly to be hoped
that his own country may be equally ready to
avail itself of these methods, and that it may
adequately prepare in advance for the ex-
tremely important as well as difficult task of
rehabilitating maimed and paralyzed soldiers
and sailors.
Committee on psychological problems of
recreation in the Army and Navy. Chairman,
George A. Coe, Union Theological Seminary,
W. C. Bagley, H. L. Hollingworth, G. T. W.
Patrick, J. H. Tufts.
This committee will serve the national cause
by cooperating in every profitable way with the
committee on military recreation of the Y. M.
C. A. and with such other agencies as are im-
mediately concerned with this kind of military
aid. Psychologists will find abundant oppor-
tunity for the study of psychological aspects
of recreational problems.
Committee on pedagogical and psychological
problems of military training and discipline.
Chairman, Charles H. Judd, University of
Chicago.
Committee on problems of motivation in
connection with military service. Chairman,
Walter D. Scott, Northwestern University,
H. S. Langfeld, J. H. Tufts.
Committee on problems of emotional stabil-
ity, fear and self-control. Chairman, Robert
S. Woodworth, Columbia University, W. B.
Cannon, G. Stanley Hall, J. B. Morgan, J. F.
Shepard.
It is probable that in addition to dealing
with the special problems of emotional stability
this committee will find it desirable to under-
take a careful study of incorrigibility.
Committee on acoustic problems of military
importance. Chairman, Carl E. Seashore,
University of Iowa, R. M. Ogden, OC. A.
Ruckmich.
Already the chairman of this committee has
interested himself in the relations of the prin-
ciples of acoustics to various naval situations.
Methods of localizing sounds and their util-
ization for the detection of submarines, the
SCIENCE
103
identification of guns, and the locating of
batteries are clearly important. These ques-
tions are under investigation by the physics
committee of the National Research Council,
with which Dr. Seashore’s committee will co-
operate.
Committee on visual problems of military
significance. Chairman, Raymond Dodge,
Wesleyan University, R. P. Angier, H. A.
Carr, L. R. Geissler, S. P. Hayes, G. M.
Stratton, L. T. Troland.
Chairman Dodge has devised and perfected
an apparatus for the measurement of various
important aspects of the naval gunners reac-
tion. This is now installed for trial on a
number of battleships. The committee has
also been requested to prepare and recom-
mend to the Navy methods for the selective
examinating of men for various kinds of
service. This work is in progress and its
results will shortly be reported to the officials
directly concerned.
If the war continues for as much as a year
American psychologists will have opportunity
to serve importantly, not only in the examin-
ing and classifying of recruits but also in the
selection of men for positions of responsibil-
ity, and in the choice and training of avi-
ation recruits, naval gunners and others in
skilled service. It is no longer a matter, as
at first appeared to be the case, of inducing
military authorities to accept methods of
psychological measurement, but instead pri-
marily one of meeting their expressed needs
and requests for assistance.
As psychological research along such lines
as have been indicated above progresses and
as the applicability and serviceability of meth-
ods are demonstrated, it is probable that
effective use can be made by the government
of all scientists who are skilled in the study
and control of human behavior. For after all,
the human factors in the war are as important
as are the mechanical and it can not be
doubted that brains and not brawn will decide
the great conflict.

WILLIAM BULLOCK CLARKE
Dr. WituiAM Buiiock OxarkE, professor of
geology in the Johns Hopkins University,
eminent for his contributions to geology, died
suddenly from apoplexy on July 27, at his
summer home at North Haven, Maine.
Wm. Bullock Clarke was born at Brattle-
boro, Vermont, December 15, 1860. His
parents were Barna A. and Helen (Bullock)
Clark. Among his early ancestors were
Thomas Clark, who came to Plymouth, Mass.,
in the ship Ann in 1623 and who was several
times elected deputy to the general court of
Plymouth Colony; Richard Bullock who came
to Salem, Mass., in 1643; John Howland, a
member of council, assistant to the governor,
and several times deputy to the general court
of Plymouth Colony, who came to Plymouth
in the Mayflower in 1620; John Tilly who
likewise came in the Mayflower; and John
Gorham, captain of Massachusetts troops in
King Philip’s War. Among later ancestors
were William Bullock, colonel of Massa-
chusetts troops in the French and Indian
War, and Daniel Stewart, a minuteman at
the battle of Lexington in 1775.
Clark studied under private tutors and at
the Brattleboro high school, from which he
graduated in 1879. He entered Amherst Col-
lege in the autumn of 1880 and graduated
with the degree of A.B.-in 1884. He im-
mediately went to Germany and from 1884 to
1887 pursued geological studies at the Uni-
versity of Munich from which he received the
degree of Doctor of Philosophy in 1887. Sub-
sequently he studied at Berlin and London,
spending much time in the field with members
of the geological surveys of Prussia and Great
Britain.
Before leaving Munich Dr. Clark was of-
fered and accepted the position of instructor
in the Johns Hopkins University. He was
instructor from 1887 to 1889, associate from
1889 to 1892, associate professor from 1892 to
1894, and professor of geology and head of
the department since 1894. He has been for
a long time a member of the academic council
—the governing body of the university—and
always took a very active interest in its
SCIENCE
[N. S. Vou. XLVI. No. 1179
affairs, acting as one of the committee of ad-
ministration while the university was without
a president.
In 1888 he was also appointed an assistant
geologist on the U. S. Geological Survey and
detailed for work on the Cretaceous and Ter-
tiary formations of the Atlantic Coastal
Plain. At the same time he was requested to
prepare the correlation bulletin on the Eocene,
one of a series of reports which were presented
to the International Geological Congress in
Washington in 1891. Professor Clark spent
the summer of 1889 in a study of the Kocene
deposits of the far west while the remaining
period was occupied in the investigation of the
Eocene formations of the Atlantic border.
He was advanced to geologist on the staff of
the U. S. Geological Survey in 1894 and held
this position until 1907, since which time he
has acted as cooperating geologist.
Professor Olark organized the Maryland
State Weather Service in 1892 of which he
was appointed the director. He has held the
position continuously to the present time. In
1896 he organized the Maryland Geological
Survey and has been state geologist since the
establishment of that bureau. The Geological
Survey was enlarged in scope in 1898 by the
addition of a highway division which was in-
structed to investigate and report on the con-
ditions of the roads of the state and the best
means for their improvement and Professor
Clarke and his associates through their pub-
lications and addresses aroused much interest
in the subject throughout the state. In 1904
the duties of the highway division were much
increased by the appropriation of $200,000
annually to be met by a similar amount from
the counties for the building of state aid roads
by the survey. A sum exceeding $200,000
was also subsequently appropriated for the
building of state aid roads by the survey, at
the expense of the state alone, of a highway
connecting Baltimore and Washington. The
duties of the highway division were trans-
ferred in 1910 to a newly organized State
Roads Commission, of which Professor Clarke
was made a member and which position he
held until 1914. Nearly $2,000,000 had been
Aveust 3, 1917]
expended, however, by the State Geological
Survey in the supervision and building of
roads up to the date of the transfer.
Under an Act of the Legislature passed in
1900 Professor Clarke was appointed com-
missioner for Maryland by the governor to
represent the state in the resurvey of the
Maryland-Pennsylvania boundary, commonly
known as the Mason and Dixon line. This
survey was completed four years later and an
elaborate report prepared. In 1906 he was
made a member of the Maryland State Board
of Forestry and elected as its executive officer,
which position he held at the time of his
death. The governor appointed him in 1908
a member of the State Conservation Com-
mission.
Professor Clarke organized and directed the
preparation of the official state exhibits. of
Maryland mineral. resources at. the Buffalo,
Charleston, St. Louis, Jamestown, and San
Francisco expositions in 1901, 1902, 1904,
1907, and 1915.. These ~ exhibits: attracted
much attention at the time and recéived ‘a’
large number of conspicuous awards. These
exhibits have been permanently installed as a
state mineral exhibit at the state house in
Annapolis.
When President Roosevelt invited the gov-
ernors of the states to a conference on. con-
servation at the White House in May, 1908):
it was arranged that each governor should
appoint three advisers to accompany him.
Professor Clark was one of the Maryland ad-
visers and took part in the conference.
After the great Baltimore fire in 1904 the
mayor of the city appointed Professor Clarke
a member of an emergency committee to: pre-
pare plans for the rehabilitation of the burnt
district and for several months he served as
vice-chairman of the important subcommittee
on streets, parks, and docks whose plans re-
sulted in the great changes subsequently
earried out. The following year he was ap-
pointed by the.mayor a member of a com-
mittee to devise a plan for a sewerage system
for the city which has resulted in the build-
ing of the present modern system of sewers.
Again in 1909 the mayor also appointed him
SCIENCE
105
a member of a committee for devising a plan
for the development of a civic center for
Baltimore.
Since 1901 Professor Clark has been presi-
dent of the Henry Watson Children’s Aid
Society of Baltimore and was a delegate to
the White House Conference called by Presi-
dent Roosevelt in February, 1909, to consider
the subject. of the dependent child. He was
also a member of the executive committee of
the State Tuberculosis Association and a
vice-president and chairman of the executive
committee of the federated charities of Balti-
more.
Numerous scientific societies have elected
him to membership, among them the National
Academy of Science, of which he was chair-
man of the Geological Section, the American
Philosophical Society, the Philadelphia Acad-
emy of Natural Sciences, the American Acad-
emy of Arts and Sciences, the Deutsche Geol-
ogische Gesellschaft, the Washington Acad-
emy of Science, Paleontologische’ Gesellschaft,
and the American Association for the ‘Ad-
vancement of Science. He was councillor and
treasurer of the Geological Society of Amer-
ica at the time of his death. In 1904 he was
élected a foreign correspondent of the Geo-
logical Society of London. He was also presi-
dent. of the Association of State Geologists.
Amherst conferred on him the degree of LL.D.
in 1908. He had numerous offers from other
institutions, perhaps the most important being
the professorship and head of the department
of geology at Harvard University, but all of
these were refused, and his devotion to Hop-
kins and the ideals for which it stood was un-
swerving.
At the time of the International Geological
Congress in St. Petersburg in 1897 Professor
Clarke was an official delegate from the United
States and spent several months in an extended
trip through Russia and its provinces. In
1906 he spent the summer on an expedition to
central Alaska, visiting the region to the north
of Prince William Sound. He traveled ex-
tensively in western America and Mexico,
reaching distant portions of the western Sierra
Madre district.
106
With the outbreak of the war Professor .
Clarke became actively interested in problems
of defense and economic preparedness.. He was
appointed a member of the National Research
Council and was chairman of the subcommittee
on road materials and a member of the com-
mittee on camp sites and water supplies. He
was also chairman of the committee on high-
ways and natural resources of the Maryland
Council of Defense.
Professor Clarke made numerous contribu-
tions to geological literature, his work being
confined largely to the Cretaceous and Tertiary
formations of the Atlantic Coastal Plain and
the Carboniferous deposits of the central Appa-
lachian region. Professor Clarke’s chief
paleontological interest was centered in the
Kchinoidea, to the elucidation of which group
he published several monographs. One of his
monuments will be the series of reports of the
Maryland Geological Survey, which set a new
standard for state publications both as to sub-
ject-matter and book-making. The systematic
reports in which he was most interested will
be of perennial service to science.
He was a member of numerous ¢lubs includ-
ing the University, Maryland, of which he was
a vice-president, Baltimore Country, Johns
Hopkins, and City Clubs of Baltimore and the
Cosmos Club of Washington.
He was married October 12, 1892, to Ellen
Clarke Strong, daughter of the late Edward
A. Strong, of Boston, and had four children,
Edward Strong, Helen, who was recently mar-
ried to Captain H. Findlay French, Atherton
and Marion, all of whom survive him.
Professor Clarke’s administrative ability
and professional attainments are largely re-
sponsible for the extensive development of
Maryland’s mineral resources and his loss will
be severely felt in all quarters. He was always
keenly interested in the educational value of
the work of the various state bureaus which he
directed and had just finished writing a geog-
raphy of Maryland for school teachers. At the
time of his death he was engaged in writing a
report on the underground waters of the state
and another on the coals.

SCIENTIFIC EVENTS
THE ASIATIC ZOOLOGICAL EXPEDITION OF
THE AMERICAN MUSEUM OF NATURAL
HISTORY
Dr. Henry Farrmeptp Osporn, president of
the museum, has received news from Mr. Roy
C. Andrews, who is in charge of the expedi-
tion. The principal work of the expedition
was done in remote regions of the province of
Yunnan, China, where no white man had ever
been seen before the explorer and his party
entered that region. Mr. Andrews is accom-
panied by Mrs. Andrews, who is the official
photographer of the expedition. The party,
since it has been in Yunnan, has ridden 2,000
miles on horseback and made camps in 107
different localities varying from 1,700 to 15,-
000 feet above the level of the sea. Mr.
Andrews says in his report, which is dated at
Hui-Yao, May 23, 1917:
The active field work of the expedition ceases
to-morrow, exactly one year since it began by our
first trip up the Min River from Foochow—a trip
which was interrupted rather seriously by the re-
bellion, but which gave us some very interesting
experiences. We have as results the following:
2,100 mammals, 800 birds, 200 reptiles, 75 skele-
tons of mammals, 8,000 feet of motion-picture film,
150 Paget natural color photographs, 300 black
and white negatives. Our attention to the subject
of mammals has, I believe, yielded the largest col-
lection ever taken out of China by a single expe-
dition. We visited first the northern alpine coun-
try along the Thibetan frontier where we were
seldom below an altitude of 9,000 feet and eol-
lected as high as 15,000 feet. The mountains
among which we were working were tremendous,
reaching as high as 18,000 feet. In this region we
were frequently with natives who had never seen a
white person. The northern trip occupied some
four months and we then started on a long jour-
ney southward to the Burma border where we col-
lected in regions only 1,700 feet above sea level,
where, of course, we found a totally different
fauna. Thus the collection covers a wide range of
climate as well as actual distance. Our large mam-
mals inelude seven gorals (Nemorhacdus) from the
Thibetan region and four serows (Nemorhacdus)
—all complete with accessory material for group
mounting. On the Burma frontier we collected
twenty-five gorals—a perfectly splendid series, all
from one mountain and of allpossible ages from
just born, young to very old males and females.
“egei:
Aveust 3, 1917]
I do not hesitate in saying that this is the finest
series of these rare animals in any museum of the
world. It is quite a different species from those
we shot in the north. A few days ago I had the
good fortune to shoot a splendid coal-black serow
—an animal quite unlike the serows of the Thibetan
border and exceedingly rare in this region. We
have also arranged to buy a fine male serow from
Fukien Province, This gives us six of these strange
animals of three different species. We have a
very large sambur (Rusa) stag in perfect mount-
able condition, ten red barking deer (Cervulus) and
two of the very rare blue, or crested, muntjacs
(Elaphodus). The collection contains twenty-five
monkeys of five species and four genera. Two
species of gibbons (Hylobates), one very small
yellow one, and another large black variety, as well
as eleven large gray monkeys (Semnopithecus) of
all ages and sexes. Six or seven baboons of two
species. Of medium-sized carnivores we have
about 50—especially Viverrines, and one fine
leopard.
The large mammals of this province, as indeed
throughout all China, are by no means abundant,
and are in widely separated districts, so that we
feel we have a fairly good proportion. The col-
lection of small mammals is especially rich in In-
sectivores, and I believe that some. remarkable
types will be found among them.
The collection of skeletons comprises all species
of large or medium sized mammals, and specimens
of each species of small mammal in formalin. Also
fetal examples of gibbon, goral, muntjac, langur,
baboon, ete., in formalin.
We collected birds whenever we were not occu-
pied with mammals and during our long journeys
between collecting points. About one third of the
collection is from Fukien Province and the re-
mainder from Yunnan.
Neither Mr. Heller nor myself has ever been in
such a poor reptile country. Some five months of
the trip, while we were in the north, the weather
was so cold that no reptiles at all were to be found.
Those we have collected were mostly taken during
the few months of our southern trip.
The photography of the expedition will, I be-
lieve, prove of extraordinary value and interest,
comprising, as it does, motion film, natural color
and black and white negatives. The Paget color
plates will be especially interesting, and have not,
I believe, ever been used upon an expedition of
this character before. The motion film shows the
general life of the people along the Thibetan
border and in the far south, and, since it was de-
veloped in the field, the suecess of the film, from a
technical standpoint, is assured.

We have met with the greatest courtesy from all
The
Chinese government has granted willingly every
request which we have made, and French and Brit-
ish officials have given us free entry of goods, re-
duced freight rates and assisted in various other
ways.
Mr. Andrews will leave Mr. Heller at °
Bhamo and proceed to Caleutta, where he ex-
pects to spend a week or ten days at the
museum comparing a selected series of his
collection of small mammals with those ob-
tained by the Anderson Yunnan Expedition
in 1875—the only other expedition which has
ever collected in that province. He will then
go to Colombo and tranship for Hong Kong—
a journey of twenty days or more. From
Hong Kong, Mr. Andrews will return direct
to New York, arriving about the end of Sep-
tember or the first of October. Mr. Heller
will probably spend some time traveling in
India, but will no doubt reach New York
about the same time.
WAR SERVICE OF CHEMISTS
Dr. JuLius Stincrirz, president of the Amer-
ican Chemical Society, and Dr. Charles L.
Parsons, secretary, have, under date of July
24, addressed the following letter to the mem-
bers of the American Chemical Society:
In accordance with the resolutions passed by the
society at the Kansas City meeting, the officers of
your society have been urging the government that
chemists, as in England, Canada and France, be
used for chemical service in the war, either in the
employ of the military branch, of the other govy-
ernment branches, or of necessary industries. A
special committee was organized by your presi-
dent, consisting of Dr. W. H. Nichols, chairman,
Drs. M. T. Bogert, A. A. Noyes, your secretary
and your president, to lay definite recommenda-
tions before the authorities. These have been pub-
lished in the July number of the Journal of Indus-
trial and Engineering Chemistry.
The government, it appears, has decided that
.there will be no general exemption of any class of
men as a class—for reasons which are eminently
wise and necessary at the present moment. At
the same time, no doubt, it is anxious to see every
man used in what appears to it to be the right
place for him. It has seemed perhaps best to make
no general ruling whatsoever, except to the effect
that there will be no class exemptions, and to leave
108
all individual cases to the federal district exemp-
tion boards, to which exemptions for industrial,
agricultural and professional reasons are left by
law.
Under the circumstances, in the absence of in-
structions from the government and in view of the
general desire on the part of our members for
guidance and advice in this matter, we would ree-
ommend to you wnofficially the following proced-
ure: Chemists of military age selected by draft
for service and accepted by the local boards to
which the physical examination, etc., is committed
are advised to submit to their federal district
boards:
1. An official certificate of their employers, or of
the university or college from which they have re-
ceived degrees or with which they have been or are
connected, certifying as to their education and ex-
perience as chemists.
2. An official statement by their employers of
the nature of their work as chemists.
3. A recommendation, if such seems right, from
their employers, or their university or college, that
they be assigned to continue their work as chem-
ists.
4, A request that in default of such assignment,
they be detailed to serve as chemists in the mili-
tary branch of the government.
5. If enlisted in any capacity, inform the secre-
tary of the society by postal card of the company,
regiment and corps in which you are enrolled, in
order that a record may be kept of the fact and
the War Department advised from time to time of
chemists in the army should their services as chem-
ists be required.
The purpose of this recommendation is to put
into the possession of the government authorities all
the facts necessary for it to decide exactly for
what service a given man is most fitted. We be-
lieve this to be in accordance with the resolutions
adopted at the Kansas City meeting and in ac-
cordance with the patriotic duty of every Ameri-
ean chemist to serve his country under the selective
draft in the capacity the government itself, with a
full knowledge of the circumstances, selects for
each individual.

DISCUSSION AND CORRESPONDENCE
REPLY TO DR. ERLANGER
On p. 384 et seq., Vol. XLV, of this journal
Dr. Erlanger criticizes an abstract of my
paper which he did not stop to hear and which
is not yet published.
Dr. Erlanger completely misses the point of
my paper and somewhat radically changes
some statements in his own paper.t
Dr. Erlanger stated that the pressure os-
cillations are in direct numerical ratio to the
manometer pressures in the compression cham-
ber; I showed that the ratio is determined by
the barometric plus the manometric pressure
—i. e., Boyle’s Law.
He says :2

out the diastolic-systolic range of compression
and since at this time, as premised above, the com-
pression pressure is nearly twice that which ob-
tained at D, the pressure in the compression cham-
ber will be raised almost twice as high by the

pulse at Z as at D; for the rise of pressure de-
termined by the addition of a given volume of in-
compressible material to a confined gas-filled space
is proportional to the pressure of the gas filling the
space.
This statement is also expressed in the dia-
gram? which is here given in photographic
reproduction. The beginning pressure is
marked zero—%. e., ignoring barometric pres-
sure—the “ diastolic pressure” marked on the
ordinate is just half way between zero and the
“systolic pressure.” The ordinates drawn to
represent the extent of oscillations are in the
same ratio, that is the “systolic rise ””—H V’—
at double the manometer pressure is just
twice that marked at NV near DV for diastolic
pressure—a ratio of 1: 2.
Boyle’s Law shows that the ratio would be
P’/P where P is the original total pressure;
P’ the new pressure produced by the addition
of a constant volume of fluid. Accordingly:
introducing V and V’ as the respective vol-
umes of the gas with K as the constant it was
found in a concrete case where V was 100 e.c.
and where 1 c.c. of fluid was added with the
barometer at 747 mm. that the ratio of the
size of the oscillations at 50 mm. (manometer)
beginning pressure as compared with 100 mm.
(797 mm. and 847 mm. total pressure) was
8.05: 8.55 or 1: 1.06 plus instead of 1:2 as per
Erlanger hypothesis.
The ratio at 0 mm. (manometer) beginning
pressure as compared with 100 mm. (manom-
eter pressure was 7.54:8.55 or 1:1.13 in-
stead of 1: infinity as demanded by the Er-
langer hypothesis.

FAUNAL CONDITIONS IN SOUTH GEORGIA
Regarding Mr. Luke’s note on the rats of
South Georgia, it may be of interest to record
that his question as to “ what characteristics
the rat would develop after a few years of such
a specialized habitat” has been at least pro-
visionally answered by the Swedish zoologist,
Dr. Einar Loénnberg. This author in 1906
described the South Georgia rat as a new sub-

species, and noted that it apparently differed
from the typical brown rat in haying a
thicker skin, denser and longer fur, and a
more rusty color. :
Several of Mr. Luke’s observations would
be hard to substantiate, for instance the state- .
ment:
Until about thirty years ago there were no rats
on the islands.
It is much more probable that these ubi-
quitous rodents were introduced in sealing
vessels not long after American and British
sealers first began to exploit South Georgia
on a large scale, which was in the year 1800.
Klutschak, who visited South Georgia in
1877, transcribed and published an American
sealer’s chart of the island, and designated
as “ Rattenhafen ” * the bay known to modern
Norwegian whalemen as “ Prince Olaf Har-
bor,” but called “Port Gladstone” on the
latest British map. Rats are still exceedingly
abundant about this inlet, as I found in 19138.
Within recent years rats are known to have
been reintroduced repeatedly at Cumberland
Bay.
The rats at South Georgia can not fairly
be accused of having “devastated the few
small animals living on the island,” unless the
birds are meant; there are no other native
land vertebrates. Rabbits were introduced
about 1872 by a sealer coming from Tristan
da Cunha, and perhaps two or three times
since, but they never gained a foothold. A
few horses and reindeer have been thriving
there in a feral state for a number of years.
The whaling industry was started at South
Georgia not “a few decades ago,” but in 1904.
Although the rats do feed upon the whale
carcasses, as Mr. Luke writes, it would be a
mistake to suppose that they are at all de-
pendent upon this source of food, for the
creatures appear to be very nearly as abun-
dant about the uninhabited fiords as they are
along the shores of the carcass-strewn bays.
I observed at Possession Bay, the Bay of Isles,
and elsewhere, that the rats eat the young

mous numbers of the smaller species of sea-
birds (Tubinares), which nest in burrows.

A PERSONAL AND FAMILY HISTORY REGISTER
To tHE Eprror or Scrence: In Sorence of
May 16, 1913, the writer called attention to a
eall made by Dr. J. Madison Taylor in an
earlier issue of Science, seeking aid and co-
operation in a plan to secure a body of trust-
worthy vital statistics, and attempted to em-
phasize the crying need of just such a de-
sideratum. It is gratifying to know that the
aim of Dr. Taylor is now realized, and that
under the above caption he has made available
a means by which such data may be intelli-
gently compiled and made permanent. The
register forms a volume, quarto in size, and
well bound, with provisions and directions for
recording personal and family traits, history
of birth, growth, health, disease, etc., and also
blanks for various supplemental data that may
be considered desirable in such a history, such
.as photographs, clinical and dental records.
The volume closes with a timely discussion
of subjects relating to human welfare, and in-
cludes such topics as The Child as a Problem
to Parents, The Building of a Citizen, En-
SCIENCE
113
vironment and inherited Tendencies, Personal
Hygiene, Age and Age Values, Development of
the Mind, all of which are presented in terms
easily understood, and at the same time with-
out sacrificing scientific accuracy.
The writer welcomes this register as a
worthy contribution toward a better under-
standing of the importance of human statistics
in relation to the imperative necessity of both
human conservation and racial betterment.
The author has spared no pains, and has evi-
dently devoted long and strenuous labor in its
production, and the publishers, F. A. Davis
Company, Philadelphia, have also done well
their part in giving to the book their usual ex-
cellence of artistic and mechanical values.

REWARDS FOR NATIONAL SERVICE
To THE Epitor or Science: The American
government has embarked in what will be the
greatest war in its history and as such de-
serves and demands the unqualified support of
its citizens and that every effort be made to
secure such services at the minimum cost.
An effort, I believe, is being made to or-
ganize and direct the inventive skill of the
American people so as to render victory more
certain, save life and property and shorten the
conflict. Abroad in many eases such services
are rendered gratuitously but the donator in
meritorious cases is rewarded by a suitable
decoration. This in many ease is prized more
highly than a monetary reward.
Since the government is making an effort
to secure such expert inventive assistance as
practicable, would it not be possible to prevail
upon the government to institute such a
decoration and if not for the American As-
sociation for the Advancement of Science, as
the greatest organization competent to repre-
sent the consensus of expert opinion to do so.

Shokabo, Nihonbashi, Tokyo, June, 1917,
3.50 yen.
Dr. T. Miyake, of the Imperial Agricultural
Experiment Station at Nishigahara, Tokyo,
has just brought out an excellent book which
will serve as the first part of a handbook of
entomology. It is beautifully printed in Ja-
panese, fully illustrated, and handsomely
bound. It deals with the morphology, physiol-
ogy and embryology of insects, a field to which,
the author states, Japanese entomologists have
hitherto made very few contributions. The
book is therefore largely a compilation, though
here and there the researches of Japanese ento-
mologists are quoted. The work is a pioneer
of its kind, and the most detailed book that has
ever appeared in Japan. It covers 347 pages
and contains 227 figures. The majority of the
figures are borrowed from German, American,
English and other writers, and are fully
credited. Some of the line drawings are ap-
parently original and are very well done.
Dr. Miyake proposes, in his second volume,
to publish a brief history of entomology in
Japan. He expects to publish four volumes
in all, the entire work to be used as a text-book
for colleges and universities. It is a pity that
European and American entomologists have
such a slight knowledge of the Japanese lan-
guage, for the book has a very attractive ap-
pearance and many would like to consult it:

HERB-GROWING IN THE BRITISH
EMPIRE
The British Medical Journal states that at
the meeting of the Royal Society of Arts on
May 2nd Mr. J. C. Shenstone, F.L.S., read a
paper on herb-growing in the British empire.
At the present time, he said, herbal remedies
occupied a more important place in the med-
ical and domestic practise in most European
countries than they did with us. When the war
broke out the discovery was made that we had
become dependent upon the Central Empires
not only for synthetic chemicals, but for the
supply of herbal medicines formerly grown
by us. Some of these plants, such as bella-
donna, henbane, foxglove, colechicum, and per-
SCIENCE
[N. S. Vou. XLVI. No. 1179
haps valerian and male fern, were indispen-
sable, but although they had belonged to our
native flora, or at least had been cultivated
in this country from very early times, their
cultivation had fallen into neglect. The same
was true of less valuable plants such as the
dandelion, poppy capsules, and camomile
flowers. As to belladonna and henbane, it
was pretty certain that their alkaloidal value
could be raised considerably without increas-
ing the cost of production, but for this pur-
pose the cooperation of the chemist would be
required. It has also been stated that the
wild foxglove of this country could supply the
market for digitalis. A medical friend who
collected his own digitalis and prepared his
own tincture had told him that he found that
foxglove growing on a hot sandy bank pro-
tected by a wood gave him the best results. Ex-
periments in producing the most active dan-
delion juice would be worth consideration.
Liquorice, most of which came from Spain
and Italy, could be cultivated in Essex and
Surry, and was already grown in Yorkshire.
Many valuable drugs imported from the
American continent were not unsuited to our
climate; Podophyllum peltatum, Linn., im-
ported from America, had figured in. our gar-
den catalogues as a decorative plant. He
begged medical men to give some attention,
in conjunction with pharmacists and botan-
ists, to investigating likely plants, for there
could be no doubt that the varied and numer-
ous flora of the British Empire would yield
medicines of even greater value than those
imported from foreign countries. Sir Robert
Armstrong-Jones, who occupied the chair,
said that there were eighty or one hundred
medicinal herbs and plants of medicinal
value; Mr. Shenstone had referred to about
forty of them, but the remainder could also
be grown practically within our empire.
There were many reasons for the decay in
the use of the medicinal herbs, but the chief
was the insinuating tablet. If herb-growing
were taken in hand, it should be done at once,
for belladonna only paid in the second year
and aconite in the third. He understood that
the shortage of digitalis had now been just
Avaust 3, 1917]
overcome. Sir George Savage referred to the
great amount of interest he found in the old
herbals in his possession, although some of
them were difficult to follow. He had spent
four years in a very wide country practise in
Cumberland, and he recalled his indebted-
ness to a man who made a great many of the
simpler remedies from dandelions and other
plants, and saved a great deal of trouble.
British bed-straw was a useful herb; in the
British Medical Journal of forty years ago
he found a note on its efficacy in certain
eases. He concluded by quoting a remark of
Rousseau to the effect that the field of botany
had not been studied by scientists, but had
been exploited by medical men who wished
the public to have faith in their simples.
SPECIAL ARTICLES
THE CHEMICAL BASIS OF REGENERATION
AND GEOTROPISM
1. Iv is a well-known fact that in many
plants after the removal of the apex some res-
toration of the old form is accomplished by
the growth of a hitherto dormant bud near the
wound. This process has been called regener-
ation. It is also well known that in certain
fir trees the old form is restored in such a case
in an apparently different way, namely by one
or more of the horizontal branches next to the
apex beginning to grow vertically upwards
(negative geotropism). One may wonder how
it can happen that the same result, namely the
restoration of the old form, is accomplished
in the organic world in such different ways;
and it is quite natural that occurrences of this
kind should suggest to one not a mechanist
the conception of mystie forces acting inside
or outside the living organism towards a
definite purpose, in this case the restoration of
the lost apex. The writer pointed out not
long ago that both phenomena, the restoration
of form of a mutilated organism by geotropic
bending as well as by the growing out of
hitherto dormant buds may be caused by one
and the same agency; namely the collection
of certain chemical substances near the
wound.! New experiments which the writer
1 Loeb, J., ScieNcE, 1916, XLIV., 210; Bot. Ga-
SCIENCE
115
has since made seem to prove this idea to be
correct.
2. In a previous paper the writer had shown
that when an isolated piece of stem of Bryo-
phyllum calycinum, from 10 to 15 em. long,
with one leaf attached to its apical end, is
put in a horizontal position the stem will grad-
ually bend and assume the shape of a U, with
the concave side upwards and that this bending
is due to the active growth of a certain layer
of cells in the cortex on the lower side of the
stem. When the same experiment is made with
stems without a leaf attached some geotropic
bending of the stem still occurs, but at a much
slower rate. From this observation the writer
drew the conclusion that the leaf furnishes
material to the stem which causes the growth
of the cortex of the lower side of the stem, re-
sulting in the subsquent geotropic bending of
the stem.2 The leaf forces this material into
that part of the stem which is situated more
basally than the leaf; since the part of the stem
situated in front of a leaf does as a rule not
show any geotropic bending. The fact that
the growth leading to the geotropic curvature
takes place in the cells of the lower side of a
horizontally placed stem indicates that the
material causing the growth collects on the
lower side of the stem, which appears quite
natural, since this material is a liquid, pos-
sibly containing some solid particles in sus-
pension. A slight leakage of sap from the
conducting vessels might be sufficient to ac-
count for such an accumulation of material
on the under side of a horizontally placed
stem.
3. Since the publication of these observa-
tions on geotropism in Bryophyllum the writer
has been able to show that the mass of shoots
which an isolated leaf can produce from its
notches is a function of the mass of the leaf
and that sister leaves of equal size when iso-
lated from the stem produce equal masses of
shoots under equal conditions and in equal
time, even if the number of shoots produced
differs considerably in the two leaves. When
zette, 1917, LXIII., 25; ‘*The Organism as a
Whole,’’ New York, 1916, p. 153.
2 Loe. cit.
116
the mass of one set of isolated leaves is reduced
by cutting out pieces from their center while
their isolated sister leaves remain intact the
mass of shoots produced by the two sets of
sister leaves varies approximately in propor-
tion with the mass of the leaves.*
If it is true that the geotropic bending of a
horizontally placed stem depends upon the
mass of material furnished to the stem by the
leaf we should expect that a reduction of the
mass of the leaf would correspondingly retard
the rate of geotropic bending in the stem. The
writer has recently carried out such experi-
ments and they corroborate this expectation.
If two sets of stems of equal length are sus-
pended in an aquarium, each with one leaf
attached to its apical end, and if the size of
the leaf is reduced in one set by cutting away
pieces of the leaf, the geotropic bending takes
place the more slowly the smaller the mass of
the leaf. It is difficult to conceive of a more
striking experiment. When the mass of the
leaf is reduced to zero, the bending is ex-
tremely slow.
4, These experiments suggest that the
growth of the cells of a horizontally placed
stem which gives rise to the geotropic bending
is accelerated by substances furnished to the
stem by an apical leaf; and that these sub-
stances might be the same as those which serve
for the formation of roots and shoots in the
isolated leaf. If this were true, a leaf attached
to a piece of stem should form a smaller mass
of shoots and roots than its sister leaf entirely
detached from the stem, since in the former
part of the material available for shoot forma-
tion should go into the stem.
It has been known for some time that a
piece of stem inhibits the shoot formation in
a leaf of Bryophyllum calycinum, but this in-
hibition was attributed by former writers to
an influence of roots formed on such a piece
of stem. By suitable experiments it can be
shown, however, that the inhibition takes place
also when no roots are formed on the stem.
It seemed to the writer that the inhibiting
influence of the stem on the shoot production
3 Loeb, J., Science, 1917, XLV., 436; Bot. Ga-
zette, 1917 (in print).
SCIENCE
[N. 8. Vou. XLVI. No. 1179
in the leaf was due, as stated, to the absorp-
tion of material from the leaf by the stem
which would have served for the growth of
roots and shoots in the leaf if the latter had
been detached from the stem; and that the
material flowing from the leaf into the stem
was causing the growth of the cells in the lower
side of a horizontally placed stem, thereby giv-
ing rise to the geotropic bending of the stem
(and incidentally also to the callus formation
at the base of the stem). If this were true
there should exist a simple quantitative rela-
tion between the inhibiting power of the stem
upon shoot formation in a leaf and the in-
crease in the mass of the stem; namely, the
two quantities should be approximately equal.
The writer has carried out such experiments
in large numbers and found that this relation
holds true, namely that a piece of stem at-
tached to a leaf increases its weight by ap-
proximately the same amount by which the
shoot production in the leaf is diminished.
For these experiments the following method
was adopted.
5. A piece from the stem of Bryophyllum,
containing one node with its two leaves, is cut
out from a plant and the stem split longitudi-
nally in the middle between the two leaves,
leaving one half of the stem attached to each
leaf. The half stem is removed from one leaf
and weighed directly. The leaf whose half
stem is cut off and the leaf with a half stem
still attached to it serve for the experiment.
After several weeks the amount of shoots in
both leaves is determined by weight and it is
found that the leaf without stem had produced
a larger mass of shoots than the leaf with a
piece of stem attached. The latter is then re-
moved from the leaf and weighed. It is in-
variably found that it has increased in weight
and that this increase approximately equals
the diminution in the mass of shoots in the
leaf under the influence of the stem. The fol-
lowing may serve as an example.
Three sets of experiments were made simul-
taneously on 6, 7 and 7 pairs of sister leaves
prepared in the way described above; one leaf

leaves without and with stems the inhibiting
action of the stem. This quantity should
equal approximately the sum of the mass of
shoots produced in the axil of the leaf at-
tached to the stem plus the increase in weight
of the stem attached to the leaf during the
duration of the experiment. The ratio of the
two values should therefore approximately
equal 1 (Table I.).
The experiments show that within the limit
of error the mass of the stem increased in such
a way as to approximately equal the inhibiting
effect of the stem on shoot production in the
notches of the leaf. The mass of roots pro-
duced in the leaves is neglected since it is
small compared with the mass of stems.
27.898 grams of shoots and the leaves with
stems 9.797 grams. The inhibiting action of
the stems, 7. e., the difference in shoot produc-
tion between the leaves without stems and
their sister leaves with stems was therefore
18.101 grams. According to our theory the
weight of the stems which were left attached
to the leaves should have increased by the
same amount. The actual increase in the
weight of the half stems attached to the one set
of leaves was in the same time 16.695 grams.
This includes the increase due to shoot pro-
duction in the axil of the leaf, which was
slight, amounting in all to less than 1.5 grams.
The two values, 18.101 and 16.695 differ by
8.5 per cent.
118
Tt seems, therefore, probable that the inhibit-
ing effect of the stem upon the mass of shoots
produced in the leaves is due to the absorption
of a corresponding quantity of material from
the leaves by the stem.
6. Summary and Conclusions—() The
writer had shown in a former note that the
mass of shoots produced in isolated sister
leaves of Bryophyllum calycinum is in direct
proportion to the masses of the leaves and that
this remains true if the mass of one leaf is re-
duced by cutting out pieces from the center of
the leaf, while the sister leaf remains intact.
In this paper it is shown that the rate of geo-
tropic bending of horizontally placed stems of
Bryophyllum calycium, if one apical leaf is at-
tached to the stem, occurs at a rate increasing
with the mass of the leaf. When the mass of
the leaf is diminished by cutting away pieces
the rate of geotropic bending is diminished
also.
(2) It had been known for a long time that
when a piece of stem is attached to a leaf of
Bryophyllum calycinum the shoot production
in the latter is diminished or completely inhib-
ited. It is shown in this paper that the mass
of a piece of stem attached to a leaf increases
by approximately the same amount by which
the shoot production in the leaf is diminished
through the influence of the stem. The infer-
ence is drawn that the inhibiting effect of the
stem upon shoot production in the leaf is due
to the fact that the same material which would
have been available for shoot production in the
leaf, had the latter been detached from the
stem, is now absorbed by the stem.
(8) This material gives rise in the stem to
callus formation and to that growth of cer-
tain cells of the cortex which causes the geo-
tropic bending; and if the buds of the stem
are not removed it causes also shoot produc-
tion on the stem. The comparatively large
masses involved indicate that this material
must consist chiefly of the common material
required for growth, 7. e., water, sugars, amino
acids, salts; but the accessory substances and
the hypothetical specific organ-forming sub-
stances of Sachs may be included in this mass;
SCIENCE
[N. S. Vou. XLVI. No. 1179
and this is suggested by the fact that on the
lower side of a horizontally placed stem, roots
grow out, while shoots grow out from the
upper side. There must, therefore, be asso-
ciated with the material which causes geo-
tropic bending also something. which favors
the growth of roots and this may be one of
the hypothetical substances of Sachs.
(4) These facts give a simple explanation
of the “resourcefulness” of the organism re-
ferred to in the beginning of this paper,
namely that plants may restore their lost apex
either by the growth of the hitherto dormant
buds near the wound or by a geotropic bend-
ing of former horizontal branches next to the
wound (fir trees). Our experiments suggest
that the cause is the same in both cases,
namely, a mass action of the nutritive, and
possibly also of some specific substances, upon
the cells of dormant buds or upon the cells of
the lower side of horizontal branches which
leads to a rapid synthesis and growth in these
cells. Without the removal of the old apex
this growth would not have taken place, for
the simple reason that the nutritive material
would have had no chance to collect near the
wound in masses sufficient for the growth.
(5) The phenomena of geotropism thus turn
out to be phenomena of mass action, probably
of the common nutritive material circulating
in the sap and they are apparently of the same
nature as the growth of dormant buds, which
is also due to a mass action of the same sub-
stances. Gravity need play only a passive:
réle, allowing masses of liquids to “ seek their
level.” In the literature of geotropism this
phenomenon is treated as a case of “ stimula-
tion,” but this treatment misses the essential
point, namely, the chemical mass action in-
volved, and it substitutes a fictitious factor,
the “stimulus” of gravitation, which in all
probability does not exist. The case is similar
to that of heliotropism when the orientation of
animals to light is treated as a “reaction to a
stimulus” instead of as an instance of the
photochemical law of Bunsen and Roscoe.

Some oxidation reactions: H. D. Gipps and C.
Conover. The investigation of the cause of colora-
tion of some compounds begun some years ago by
the writers while in the tropics was described.
Since all of the reactions which were encountered
were catalyzed by light, the studies were greatly
facilitated by the intense sunlight of the tropies.
These investigations are now being extended to
other catalytic reactions which promise some com-
mercial importance.
The action of aluminum chloride upon aromatic
hydrocarbons: Gustav Equorr and Rosert J.
Moorr. Benzene, toluene, xylene, cumene and cy-
mene were distilled over a period of twenty-four
hours with ten per cent. by weight, of aluminum
chloride in order to determine the percentage
yields of reaction products. The results in terms
of percentages, were as follows:

The naphthene formed during the above reactions
proved to be hexahydrotoluene. Traces of phenol
were noticed in all the reactions, the toluene, in
particular, yielding one per cent.
A study of the nitrogen distribution in different
soil types: C. A. Morrow. The study was made
on two peats, one muck, seven mineral surface
soils and one subsoil, all from Minnesota. The
method of Van Slyke’s protein analysis was used
throughout the investigation because the nitrogen
could be separated into a larger number of frac-
tions than by the employment of earlier methods,
The most significant fact brought out by this
study is that the organic nitrogen distribution in
different soil types is very uniform. This is to be
expected, since the nitrogen distribution in soils is
an average distribution of all the plant and ani-
mal nitrogenous products that find their way to the
soil.

New derivatives of arsanilic acid: OurveR KamM.
A new series of acyl derivatives of arsanilie acid
has been prepared; viz., the halogen-benzenesul-
fonyl derivatives, and their physiological action
has been studied. The introduction of halogens
increases the toxicity of these arsenie compounds.
Tetraphenylmethane: OutveR Kamm. The ac-
tion of phenylmagnesium bromide upon various
ethers of triphenyl carbinol has been studied.
This reaction was found very convenient for the
preparation of tetraphenylmethane, the yield in
the case of the phenyl ether being 20 per cent.
Oxidation products of alkaline copper sulphate
on lactose: W. Ler Lewis. ‘The products are
mainly galactasido acids whose hydrolysis yields
galactose and acids containing from one to six
carbon atoms. One hundred grams of anhydrous
lactose gave 9.65 gms. of carbon dioxide, 3.06
grams of formic acid and 97 grams of nonyolatile
syrupy acids. The hydrolysis of these later gave
29.30 gms. of galactose, 52.90 gms. syrupy acids
and 0.486 gms. of oxalic acid. The analysis of
these syrupy acids has so far yielded 14.26 gms. of
mannonie lactone, 4 gms. of glycollie acid and the
residue gives evidence of trioxy butyrie acid and
d-1 glycerinic. The origin of these acids is found in
the explanation of Nef. Intermediate galactasido
hexose dienols are formed whose dissociation and
oxidation logically account for the products. The
presence of such large amounts of mannonie lactone,
obtained also from maltose, must originate in a
benzillic acid rearrangement of galactasido-gluco-
sone, and sharply differentiates the oxidation of
the simple hexoses from the reducing disaccharoses.
The glucosido acids clearly explain the lesser re-
ducing power of the latter.
The oxidation of ethyl alcohol by means of alka-
line potassium permanganate: Wm. LiuoyD EVANS
and JessE E. Day. In neutral aqueous solutions
of potassium permanganate at 25°, 50° and 75°,
ethyl alcohol is oxidized exclusively to acetic acid;
in alkaline solutions of the same reagent, acetic,
oxalic and carbonic acids are the reaction prod-
ucts. A continuous increase in the concentration
of the potassium hydroxide produces a correspond-
ing increase in the yield of oxalic and carbonic
acids, and a diminution in the yield of acetic acid.
An increase in the temperature of the reaction
tends to increase the yield of oxalic and carbonic
acids and a diminution in the yield of acetic acid.
The oxidation of acetaldehyde by means of alka-
line potassium permanganate: WM. Luoyp Evans
and HoMeEr B. ADKINS. The same general results

deseribed for ethyl alcohol in the previous ab-
stract.

Seasonal distribution of soil and fecal strains of
the colon-aerogenes group in surface waters:
Myrtite GREENFIELD and W. N. Sxourur. A sur-
vey was made of five surface water supplies,
equipped with rapid sand filters, with the object of
determining the variation of the organisms of the
colon-aerogenes group during wet and dry weather,
and their response to treatment. During rainy
weather, the soil strains of the colon-aerogenes
group predominated in raw water. During ex-
tremely dry weather, fecal strains of the colon-
aerogenes group predominated in raw water, par-
ticularly if there was much sewage pollution.
There seemed to be no difference between soil and
fecal strains isolated from raw water in their re-
sistence to treatment.
Legal status and work of the water and sewage
laboratory of the state board of health: C. C.
Youne. The laboratory was for many years de-
pendent for support upon direct appropriation to
the university by the legislature and there never
were adequate funds with which to do the work
demanded. The 1915 legislature passed a law re-
quiring annual analyses and inspections of water
supplies and providing for rules and regulations
to be drawn up by the State Board of Health and
fees to cover the cost of the work. There has been
practically no objection to the law, which has been
in operation since July 1, 1915. Six thousand
samples were examined last year and abundant data
have been collected on the operation of the purifica-
tion plants of the ground-water supplies.
The problems of water supply of a great rail-
road system: Orton T. Rers. Railroads have to
deal with all sorts of water conditions, dependent
upon the location of their lines. As the road de-
yelops old sources of water supply become inade-
quate or are found harmful. Water surveys be-
come necessary in order to secure the best pos-
sible supplies. The relatively small number of suit-
able waters for boiler use make it necessary to
treat the greater number of waters in order to
render poor water supplies suitable for boiler use.

Well waters of Chicago: EDwaRD Bartow. An
investigation was made of the source, quality and
method of obtaining the thirty million gallons of
well water used each day in Chicago and the effect
of removing this quantity of water. Water can be
obtained from wells in the Chicago area in suffi-
cient quantities for many manufacturing purposes.
Amounts of water up to 20 gallons per minute can
be obtained from wells less than 500 feet deep.
For larger amounts, wells should be sunk to a
depth of 1,600 feet. Salt water is reached at
about 1,700 feet. Water from less than 500 feet
can be used satisfactorily in boilers, but the water
from the deeper wells can not be used without
softening. For cooling purposes water from 350
feet having a temperature of 52° Fahrenheit and
from 1,600 to 1,700 feet having a temperature of
57° Fahrenheit is available. Hydrogen sulfide is
found only in water from the Niagara limestone.
Water free from hydrogen sulfide can be obtained
by casing off the Niagara limestone, extending
the casing through the Maquoketa shale.
The vertical distribution of dissolved oxygen
and the precipitation by salt water in certain tidal
areas: J. W. SALE and W. W. SKINNER. It was
shown that the lower layers of certain tidal waters
under investigation contain less dissolved oxygen
than the upper layers. Evidence is presented to
show that this phenomenon is caused by the
stratification of the water due to the specifie grav-
ity of the under-run of sea water which cuts off
vertical circulation, and to the subsequent de-
pletion of the oxygen in the lower layers by nat-
ural agencies. The depletion of oxygen is found
to be greatest in September. The precipitation
and sedimentation of matter in tidal areas by sea
water is presented in graphic form. Those data
are considered to be of particular interest from
the viewpoint of fish and shell fish life.

takes therein two years more work, at the end
of which time—a total period of four years—
he receives his B.S. degree. B, taking a pre-
ponderance of prescribed physical, chemical
and biological sciences, at the end of four
years, all spent in the college, also receives his
B.S. degree. C, entering the same college, but
in addition to the required physical, chemical
and biological sciences, adding thereto the spe-
cial study of literature and the arts, at the end
of three years in the college transfers to the
medical school and in one year more, or after
a total period of four years, receives his A.B.
degree. D, entering the college and not in-
dulging in a preponderance of the physical,
chemical and biological sciences, but giving
special attention to literature and the arts, re-
ceives his A.B. degree at the end of four
years. Thus, each receives a bachelor’s de-
gree at the end of four years. If all four
continue in the schools in which they were
working at the time they received their
bachelor’s degree, B and D will-receive their
master’s degrees at the end of another year and
their doctorate degrees in science and philos-
ophy, respectively, at the end of three years.
Similarly A and C, after two and three more
years respectively in the medical school and
one year in an approved hospital or laboratory,
will receive their doctor’s degrees in medicine.
Therefore at the end of seven years in the
eases of A, B and D, and of eight years in the
case of (, all four have attained the doctorate
degree. It would appear that men starting on
the new three-year graduate courses in medi-
cine offered by the University of Minnesota in
the clinics and laboratories in the Medical
School in Minneapolis and in the Mayo
Foundation in Rochester, already have spent
as much time in making their approach to the
study of medical specialties as that required
for obtaining the Ph.D. or D.Sc. degree in
good institutions.
It is improbable that the native ability, the
preparatory school instruction, the habits of
study or the skill of their university instruct
ors, in the long run, is either better or worse
in the group of doctors of medicine than in
that of doctors of philosophy or science. Yet
all will agree that, broadly speaking, there is
a difference in the scientific attitude and
habits of thought in the men of the three
Avcust 10, 1917]
groups. This difference is best explained by
the fact that of the four students whose scho-
lastie careers have been diagramed above,
B and D have usually placed most intensive
study on a very small field of science or art,
while A and C have given less intensive study
to a relatively much broader field. Inciden-
tally also, A and C are apt to have come more
closely in contact with living conditions, with
science in the making as it were, than have
Band D. The question is open to discussion
whether B and D may not have concentrated
too early and may not later suffer from lack of
a broad knowledge of the science in the narrow
field in which they have specialized and of
other sciences related thereto. Some of the
possibilities in this respect are pointed out by
Stephen Leacock in one of his delightful
“Essays and Literary Studies.” Be this as it
may, certainly A and C at least should be
well able to see the broader relationship of
narrow lines of scientific investigation. The
question of present concern, however, is not the
breadth of their culture—which unfortunately
is usually all too narrow to enable them to get
the most real enjoyment out of life—but rather
the amount of their scientific ability, 2 e.,
their ability to utilize in new ways old scien-
tific truths and to discover, as well as to util-
ize, new scientific truths.

his native ability or the amount of his pre-
medical and graduate study not represented by
formal schooling. But in comparing large
groups these factors may fairly be assumed to
approximately cancel each other.
Turning then to the question in hand—
namely, the relative scientific ability of men
who have ended their schooling with the at-
tainment of the M.D. degree as compared with
those who have obtained the Ph.D. degree, we
may, I think, start with the premise that med-
ical science in America has at least kept
abreast with any other science during the last
quarter of a century. We might indeed be
within the truth in saying that it has led in
development, but for the purpose of the pres-
ent essay, it is but necessary to assume that
it has been equal to any other. The second
premise, which we may lay down without
question, is that the progress in medical sci-
ences has been made by the men who are in the
medical profession. It may further be postu-
lated that in the United States most of the
men who are responsible for the progress of
medical science are members of the various
medical societies whose membership is limited
to those who have attained some distinction in
some special field of medicine. It is presum-
able that there are instances of general prac-
titioners who are not members of any society

The estimation of the relative scientific
ability of members of the various groups is
very difficult. Even if we could measure accu-
rately each individual’s scientific accomplish-
ments we still might be in the dark concerning
of the kind herein analyzed, and who yet have
added materially not only to the practise, but
also to the science of medicine. Such indi-
viduals, however, must be so few that their
omission would have relatively little to do with
130
the figures or the question in hand. I have,
therefore, taken the membership lists of the
various medical specialists’ societies in the
United States of which the data were obtain-
able, and have analyzed the scholastic attain-
ments of the members as a matter of compari-
son. Elimination of duplicate memberships
has not been attempted since it would have
been both difficult and unfair.

Membership in these clinical medical soci-
eties presupposes the possession of the M.D.
degree. It is interesting to note that, taken
as a whole, 56 per cent. of the 861 members
have the M.D. degree only, while 44 per cent.
have the M.D. with some other earned degree.
It is also interesting to note that only 2 per
cent. of the 861 members have the Ph.D. de-
gree in addition to the M.D. degree.
An analysis of the scholastic degrees of the
societies covering the fundamental medical
sciences is shown in Table II. In these, the
possession of the M.D. degree is not obligatory
for membership. Of the total 1,840 members
73 per cent. of the total 2,701 have the M.D.
degree, or the M.D. with the A.B. degree or its
equivalent. Thus, it would seem that 73 per
cent. of the men who have been responsible for
the progress of American medicine started
with only the scholastic equipment, at least
so far as is indicated by their degrees, of the
men now entering upon the study of specialties
in medicine, while only 15 per cent. have the
Ph.D. or B.Se. degree.
Probably one third of the 2,701 members of
the medical societies here studied are dupli-
cates. In order to get a larger list and at the
same time cover a broader field I have made

earned degrees of 3,446 persons engaged in
any of the physical, chemical or biological
sciences (including medicine), whose names
appear in the 1915 edition of “ Who’s Who in
’ America.” The inclusion of a name in this
publication indicates that its holder has at-
tained a certain amount of public eminence
though not necessarily of a kind indicated by
his degree. An analysis of the degrees of
these 3,446 persons shows that 48 per cent.
have the M.D. degree, 20 per cent. have the
M.D. only, 26 per cent. have the M.D. plus
the A.B. or its equivalent, 2 per cent. have
the M.D. plus the Ph.D., 23 per cent. have the
Ph.D. without the M.D. and 29 per cent. have
degrees other than M.D. or Ph.D. It there-
fore appears that in the field of physical, chem-
ical and biological sciences the sort of emi-
nence indicated by registry in “‘ Who’s Who”
has been attained by twice as many with the
degree of M.D. as with the degree of Ph.D.
An analysis of similarly selected names in
“ American Men of Science” was begun but
abandoned since it was found that the latest
(1910) edition does not include the names of
many of the younger men who are largely re-
sponsible for the present progress of American
medicine.
Until the later years of the last century the
teaching of medicine in America, except in a
very few schools, was a travesty on pedagogy.
During the present century it has probably
improved more than the teaching of any other
science. To-day the man who obtains the
M.D. degree from an institution with the
equivalent of the “ Minnesota standard,” 2. e.,
including a final year’s hospital or laboratory
work, probably has quite as much scientific
ability as the man who obtains the Ph.D. or
D.Se. degree from the same institution. This
seems to be proved by the time he must study,
by the character of the subject-matter of his
studies, and by the probability of his accom-
plishing something in science in after life.
If this be true and the M.D., Ph.D. and D.Se.
degrees from high-grade institutions represent
an equivalent training, it must then appear
that the three years of graduate training in a

special branch of medicine now offered by the
University of Minnesota should result in sci-
entific ability just three years “to the good”
of that represented by any one of the three
doctorate degrees.

SCIENTIFIC EVENTS
THE RESEARCH CORPORATION
THE Research Corporation was incorporated
in the State of New York in 1912 on the
initiative of Dr. F. G. Cottrell, who gave to
it his patents concerning the process known
as the “electrical precipitation of suspended
particles.” The objects of the corporation
are:
First: To build up a business organization which,
so far as possible, should be a model of efficient
administration, for the purpose of demonstrating
the commercial value of the precipitation proc-
esses included in the original gift and of such
other inventions as the corporation might acquire
by gift or otherwise, and of making such inyen-
tions a source of profit.
Second: From the profits so earned to accumulate
an endowment fund to be used for the intensive
study of scientific and industrial needs, and to
provide the means, through the testing of new
discoveries and through study, investigation and
experimentation, of supplying such needs.
During the year 1916 the pioneer period in
the application and development of the elec-
trical precipitation processes may be said to
have been completed. The corporation, which
began with a cash capital of ten thousand
dollars, is now spending that amount every
month and has in its service a staff of forty-
five engineers and others engaged in field and
office work. The assets of the corporation as
reported by the auditors on February 16, 1917,
in cash and securities, were $217,862.72. A
laboratory has been established and experts
have been employed to study the workings of
the precipitation processes, and, if possible,
to develop improvements and meet new prob-
lems. Careful consideration has also been
given to other patents and processes which
have been offered to the corporation, and
132
although none have as yet been accepted, it is
the purpose of the corporation to lend its
aid to the utilization of any invention or dis-
covery which offers sufficient promise of pro-
moting the application of scientific discovery
to the industrial arts.
For the purpose of encouraging scientific
research directed to the development of the
industrial arts the research corporation offers
a fellowship of the annual value of $2,500, to
be awarded on competition under the follow-
ing conditions:
1. The competition will consist of the submis-
sion of evidence of scientific attainments, discov-
eries or inventions, and of special fitness for ad-
vanced work.
2. All persons desiring to compete must fill in a
form of application, which will be furnished by
the secretary of the corporation upon request, and
file the same on or before October 1, 1917, to-
gether with such letters of reference, scientific pub-
lications and other documents or evidence as they
may desire to submit, including a specifie state-
ment of the particular field or object of the re-
search or investigation which the competitor pro-
poses to conduct and a pledge that he will devote
himself faithfully to the prosecution of such re-
search or investigation if awarded the fellowship,
3. The competition shall be decided on or before
December 1, 1917, by a jury consisting of the
president of the National Academy of Sciences,
the secretary of the Smithsonian Institution, the
presidents of the American Chemical Society and
Research Corporation, respectively, and the chair-
man of the Engineering Foundation, or such per-
sons as they may respectively designate to act for
them.
4. The term of the fellowship shall be one year
from the date of the award, but the term may be
extended by the corporation for two renewals of
one year each in exceptional cases upon the recom-
mendation of the jury.
5. The stipend of each fellowship will be paid
as follows: $300 on the award of the fellowship
and $200 monthly thereafter for the remainder of
the year.
6. Fellows will be required to report in writing
at the office of the corporation within twenty days
from the date of the award (unless the time shall
be extended) and to begin their research or in-
vestigation at once. In case of their failure to do
so, or in case they shall fail to prosecute the same
SCIENCE
[N. S. Von. XLVI. No. 1180
with proper attention, the fellowship may be ter-
minated by the corporation.
7. Any fellow who shall resign or retire before
the conclusion of the term of his appointment, or
who shall be dismissed by the directors of the cor-
poration for cause, will forfeit all privileges and
emoluments of his fellowship and have no claim to
the further payment of his stipend.
8. The corporation will endeavor to secure for
fellows the privileges of laboratories specially
adapted for their particular work.
9. Each fellow shall make a written report to
the corporation at the conclusion of his appoint-
ment of the results of the research or investiga-
tion which he has conducted. Any discovery or in-
vention which he may make shall be deemed his
personal property.
ANTHRACITE COAL MINED IN 1916
THE anthracite mined in 1916 amounted to ~
78,195,083 gross tons, valued at $202,009,561, a
decrease in quantity of 1.6 per cent. and an
increase in value of 9.4 per cent. compared
with 1915. The shipments decreased 1.7 per
cent.—from 68,666,456 gross tons in 1915 to
67,501,363 tons in 1916. The shipments of
prepared coal of sizes above pea in 1916 were
40,747,215 tons, a decrease of 1.1 per cent.;
the shipments of pea size were 7,520,804 tons,
a decrease of 8.4 per cent.; and the shipments
of steam sizes smaller than pea were 19,233,-
344 tons, a decrease of but .05 per cent. com-
pared with 1915. There was an increase of
nearly 6 per cent. in the quantity of anthracite
sold locally and used by employees and a de-
crease of 2.4 per cent. in the quantity used
for mine fuel. The compilation of these sta-
tistics has just been completed by C. E.
Lesher, of the United States Geological
Survey, Department of the Interior.
The effect of the extraordinary demand for
steam sizes of anthracite that followed the in-
dustrial activity in 1916 and the high price of
bituminous coal is indicated in the figures
showing the output of washery product and
dredge coal. Although the freshly mined coal
in the anthracite region, including Sullivan
County, showed a decrease of 2.6 per cent. in
1916 compared with 1915 there was an in-
crease of 19.6 per cent. in the quantity of
anthracite obtained from the washeries, which
Avueust 10, 1917]
operate mainly on old culm banks, and an in-
crease of 16 per cent. in the quantity of coal
dredged from rivers.
The production in the Lehigh region was
10,929,055 gross tons; in the Schuylkill region,
23,659,448 tons; in the Wyoming region, 43,-
111,732 tons; and in Sullivan County (Ber-
nice Basin), 494,848 tons.
There was a large decrease in the number
of men employed in the production of anthra-
cite in 1916, and the output was maintained
only through an increase in the number of
working days. The number of men employed
in 1914 was 179,679; in 1915, 176,552; and
in 1916, 159,869. The average number of days
worked was 245 in 1914, 230 in 1915, and 253
in 1916. The average output per man per
day in 1914 was 1.84 gross tons; in 1915, 1.96
tons, and in 1916, 1.93 tons. The average out-
put per employee for the year was 451 tons
in 1914; 450 tons in 1915; and 489 tons in
1916.
ANIMAL COLLECTIONS FROM AUSTRALIA
THE animal collections of the Zoological
Park have been enriched by the arrival of
another great “caravan” from Australia.
After six months of diligent effort, and gen-
erous expenditures of money, Mr. Ellis S.
Joseph brought together and _ successfully
transported to New York the largest collection
of rare species of mammals, birds and reptiles
that ever came to America. The common spe-
cies, such as for years have been coming to us
through the regular European channels, are
conspicuous by their well-nigh complete ab-
sence.
Naturally, the officers of the Zoological So-
ciety feel measurably elated over this coup, at
a period of great depression in the wild-animal
supply from other sources. The receipts from
England are very trifling, and from the con-
tinent of Europe nothing whatever comes. In
fact, in America the German wild-animal
business is thoroughly dead. Our further
operations in South Africa must be postponed
until after the war.
Encouraged through his previous reception
by the Zoological Society, Mr. Joseph re-
SCIENCE
133
doubled his former efforts to bring to America
something worth while. The collection which
he landed in Victoria, B. C., a month ago rep-
resents a large outlay in money and effort, and
great scientific value. Of that importation
the Zoological Society has purchased mammals, '
birds and reptiles to a total cost of about
$6,000. The Philadelphia Zoological Society
has purchased $3,000 worth, and other pur-
chases are proceeding.
The following list shows the newly acquired
mammals:

hyraxes,
water mongooses,
echidna,
rabbit-eared bandicoots,
West Australian rat kangaroos,

THE Journal of the American Medical Asso-
ciation states that the Academy of Medicine
of Toronto has adopted a resolution calling for
one united medical service in Canada to take
the place of the present arrangements of a Ca-

Hospitals Commission. The academy urges
that medical care of all soldiers be placed di-
rectly under a surgeon general, to be known
as Surgeon General of Canada, who should be
directly responsible to the minister of militia,
who should have a seat in the militia council.
He will perform the duties of director of med-
ical services, invalids and be chief medical
officer of the hospitals commission and of its
executive. The academy recommended Sur-

THE annual meeting of the Incorporated So-
ciety for Extending the Rothamsted Experi-
ments in Agricultural Science was held on
November 6. According to the report in the
London Times Lord Crawford, president of
the British Board of Agriculture, moved a
resolution declaring that the work of the so-
ciety was a matter of national importance de-
serving wide public support. He said that
much would be expected from agriculture after
the war, and much more, therefore, would
have to be drawn from the knowledge, experi-
ence and guidance of such societies as that of
Rothamsted. It would be really deplorable if
any single branch of its activity had to be
dropped during the war. It was at Rotham-
sted that the first practical demonstration of
the value of artificial manures was consum-
mated. He was fully conscious of the urgent
necessity for the comprehensive treatment of
this great subject, but the time was not yet
ripe for any public announcement. Mean-
while, he trusted that the work of Rothamsted
would continue and, in spite of the war, ex-
tend in the sphere and scale of its operations.
In any future scheme he was certain that
Rothamsted would take a high and honorable
place, and would contribute to the research
which was essential to the future of British.
agriculture. Dr. E. J. Russell, the honorable
secretary and director of the Rothamsted Sta-
tion, stated that the ordinary work at Rotham-
sted had been curtailed, but it was not being
SCIENCE
137
allowed to drop. Women had been brought in,
and when peace came the men would come
back to find the experiments a stage more de-
veloped than when they left. They could see
the possibility of using to the great advantage +
of agriculture some of the machinery which
was now being used for non-agricultural pur-
poses. They hoped for some well-considered
scheme for agricultural development in which
the research stations, colleges, agricultural in-
stitutes and similar organizations would play
a definite part.
Nature remarks: “ The science of economic
aviculture has probably reached a _ higher
standard in the United States than in any
other part of the world. This work is carried
on by the Department of Agriculture, which,
for years past, has spared no pains to enact
laws and formulate schemes for the conserva-
tion of bird-life, whether for purely economic
ends or for esthetic reasons. As a consequence,
it has now available a mass of evidence as to
the status and value of every species within
its realms. The latest evidence of its enlight-
ened policy takes the form of a bulletin—No.
465—on the propagation of wild-duck foods.
The haunts and food values of no fewer than
nineteen groups of plants, comprising sixty
species, are here described, together with in-
structions as to stocking water in need of bait
for these valuable birds. The characteristics
of wild rice, wild celery, pondweeds, arrow-
heads, chufa, wild millet and water-lilies are
all carefully set forth, and this information is
accompanied by carefully collected data as to
their attractiveness in regard to particular
species of wild ducks. Had we followed its
lead years ago our own Board of Agriculture
would now be able to speak with authority
when called on to sift the value of the crudely
formed opinions of local agricultural cham-
bers as to the usefulness or otherwise of our
native birds in relation to our food supply.
The latter is of vital importance, and the
clamor for legislation is sometimes insistent.
This war has done much for us already; per-
haps it may yet bring into being a bureau of
ornithology, such as is to be found now in
138
many Continental states, as well as in Amer-
ica.”

dition, the following were elected on the
council as representing cities containing a min-
imum of five members of the society: M. I.
Golenkin (Moscow), E. F. Votéal (Kiev), V.
M. Arnoldi (Charkov), B. B. Grineveckij
(Odessa), V. V. Saponznikov (Tomsk), Ja. S.
Medyédev (Tiflis) and V. M. Arcichoyskij
(Novoéerkassk). The number of the acting
members of the society now exceeds 280. Not-
withstanding the present unfavorable condi-
tions, more than eighty members attended the
four days’ meeting in Moscow, and, in addition
to the discussion and settlement of various
questions of organization, sixteen scientific
reports were read. The next extraordinary
meeting is fixed for December, 1919, again in
Moscow. Thanks to a subsidy of 3,000 roubles
received from the Ministry of Public Instruc-
tion, it was possible towards the end of the
year 1916 to proceed with the publication of
the Journal of the Russian Botanical Society,
and the first issue was placed before, and ap-
proved by, the Moscow meeting. The second
issue is in the press and finishes the year 1916.
- For this year a subsidy of 10,000 roubles is be-
ing applied for, and it is intended to publish
eight numbers of four to five sheets each.
Thus the scientific amalgamation of Russian
botanists, for which they have long striven,
may be considered as achieved, and the forma-
tion under the auspices of the Imperial Acad-
emy of Sciences of the first all-Russian learned
society is an accomplished fact.
Nature states that under the title of “ Sci-
ence in Russia” a new reference-book will be
SCIENCE
[N. S. Von. XLVI. No. 1180
published in the present year, composed of two
parts: (a@) an index of all scientific institu-
tions, societies, and higher schools in Russia;
(6) an index of all persons working in these
institutions and of private scientific workers.
It will thus include in the first part the par-
ticulars hitherto supplied (but very incom-
pletely as to Russia) by the “‘ Minerva Jahr-
buch ”; while the second part will be similar
to “ Who’s who in science,” but will give, at
least for 1916, not so much information about
each individual. The difficult task of collect-
ing the necessary material is already well in
hand. The undertaking has been brought,
through the Russian newspapers, to the knowl-
edge of all those interested, and special forms
are being supplied to the institutions and
societies, many of which have already been re-
turned with the necessary particulars. The
work has been taken in hand by the Academy
of Sciences of Petrograd and the scientific
periodical Priroda (Nature) of Moscow.
“Science in Russia” for 1916 will be edited
by Professor V. N. BeneSevié, and published
conjointly by the Academy and the -Journal
Priroda in the latter part of this year. It will
be issued annually. This publication will
supply a long-felt need, as up to the present
the only work of reference containing any in-
formation about the scientific institutions of
Russia as a whole has been “ Minerva.” “ Sci-
ence in Russia” will help towards an exact
evaluation of Russian scientific forces and
activity, and will constitute an important step
towards the promotion of closer scientific rela-
tions with the Allied countries.
AccorpDiInG to the Journal of the American

ton, secretary. The chief object of this de-
partment will be to examine soldiers for mental
and nervous disorders and to arrange for their
treatment, but specialists of various sorts of
physical disease will also volunteer their serv-
ices. The purpose is to have volunteers go to

and if it is accepted, patients from Camp
Admiral will be treated there. The psycho-
pathic building will also be useful in treat-
ing soldiers returned from the front, 18 to 20
per cent. of whom, it has been found in Eng-
land, are suffering from mental breakdown,
temporary or permanent.

DISCUSSION AND CORRESPONDENCE
CLIMATIC INDEX OF BONNEVILLE
LAKE BEDS
Because of the fact that they have been
thought to furnish undoubtable stratigraphic
testimony in support of the conception of the
duality of the Glacial Epoch the lacustral
deposits of the Great Salt Lake basin of Utah
hold at this time an especial interest. Where
best exposed these beds occupy a vertical space
of about 100 feet; but their total thickness is
without question considerably greater than this
figure. The main body of the formation com-
prises fine laminated calcareous materials, of
uniform texture and yellow color. An upper
section, of irregular thickness, from 2 to 20
feet, is notably limy, white and more or less
indurated in certain layers. The white marly
upper capping is sharply separated from the
yellow lower beds by an irregular line of junc-
ture which has every appearance of being a
marked plane of unconformity.
The common historical interpretation of
the general section is briefly this: The lower
yellow beds are regarded as representing river
silts deposited in the lake over a very long
‘period of time when the early Bonneville
water-level was nearly as high as the later
Bonneville shore-line. The white marly beds
are depositions of a shorter high-water stage
of the lake. The irregular line between the
white and yellow sections are viewed in the
140
light of an unconformity, the interval repre-
sented being a stage between two high water
marks when the old lake-waters completely
dried up. Early Bonneville yellow beds are
correlated in time with a first epoch of humid-
ity superinduced by conditions of glaciation;
while the white later Bonneville beds belong
to the second Glacial epoch. The two parts of
the section are thus represented as being sep-
arated by an erosional interval of long dura-
tion, occupying a time between two epochs of
large rainfall and notable ice-forming.
Two features in particular militate strongly
against these deposits either being normal
stream-silts or being laid down during two
distinct epochs separated by a long epoch of
excessive dryness. This simpler and very dif-
ferent interpretation for the phenomena pre-
sented does not postulate violent and frequent
changes of climate. It appeals to no other
than the ordinary climatic conditions and
geologic processes that prevail to-day in the
region. It takes into account only the famil-
iar geological activities of the desert.
Close examination of the deposits discloses
the fact that they are not typical stream-silts,
but that they have a grain very much coarser.
In size the individual particles appear to be
about midway between those of normal clay
and fine sand. Although obscurely laminated
the material in all physical aspects seems to
be essentially loess or adobe. Thus, instead
of being normal river-silts swept into still
water these deposits really represent dusts,
borne by the winds from the neighboring
deserts, that have dropped on the surface of
the lake waters and have settled to the bottom.
Compared with desert deposits of other re-
gions the white marly upper beds of the sec-
tion which have such a variable thickness are
essentially what the Mexicans call caliche.
It is formed through ordinary soil tension by
which lime salts of porous formations below
are carried to the surface of the ground, where
the water evaporates, leaving behind the solids.
In some places there is sufficient lime de-
posited interstitially to give the beds the as-
pect of chalk. Upon further induration some
layers passed into limestone.
SCIENCE
[N. S. Von. XLVI. No. 1180
The juncture of the yellow and white beds
is a sharp, irregular line that is easily mis-
taken for an erosion uncomformity. That it
is not at all probable that in the Bonneville
basin this line actually represents uncomform-
able relationships between the beds above and
those below is clearly indicated by the fact
that the phenomenon is a common one through-
out arid lands where porous formations reach
sky.
The yellow Bonneville clays do not appear,
therefore, to represent a deposit which was
laid down during a high-water precursor of the
high-stage Lake Bonneville; and the irregular
line separating the yellow and white sections
does not stand for a long interlacustrine epoch
when the lake waters were completely desic-
eated, during a dry interglacial time. The
white marls seem to be very recent in forma-
tion, produced directly from the yellow clays
long after Bonneville waters had finally re-
ceded. Their especial climatic significance
is manifestly very different from that formerly
postulated. The ascribed peculiarities are
really every-day desert phenomena.

NOTE ON THE SWELLING OF GELATINE AND
AGAR GELS IN SOLUTIONS OF
SUCROSE AND DEXTROSE
Tue tests reported in this note were made
incidentally in connection with experiments
by D. T. MacDougal? on the swelling of cactus
tissues (Opuntia) and of certain artificial gels
in water and in dilute solutions of acids and
alkalis. The method was the same in all par-
ticulars as that described by MacDougal.
Small plates cut from thin, dried sheets of
the various gelatine-agar mixtures were
placed in the sugar solutions and the increases
in thickness which occurred as these plates
imbibed water and swelled were measured by
the auxograph. The experiments were at room
temperature, which ranged between 60° and
70° F. (16° and 21° C.). In all cases the gels
were the identical preparations used by Mac-
Dougal. The sucrose was the usual “ec. p.”
grade. The dextrose was Merck’s “highest
purity.” The sugar solutions were tested for
neutrality to phenolphthalein. and litmus.
Sugar concentrations are in percentages by
weight.
The results are given in the following tables
as percentage increases in thickness of the
gel plates after approximately 12 hours in the
respective solutions. The original thicknesses
were measured by a micrometer gauge. Pre-
liminary tests for longer time periods indi-
cated that the swelling was always complete
or very nearly so, in 12 hours. In the tables,

For the sugar solutions having concentra-
tions less than 25 per cent. the results do not
differ from the results for distilled water more
than is explainable by the accidental variation
normal to the method when the temperature is
not controlled precisely. The effects of one
hundredth normal acid and alkali found by
MacDougal were many times the variations
here observed and one may conclude that
neither sucrose nor dextrose, in concentrations
under 25 per cent., has any important effect
on the swelling of gelatine-agar gels in water;
important, that is, in comparison with the
effects of acids or alkalis. With sugar con-
centrations of 50 per cent. the data show a
markedly lessened swelling of all the gels in
sucrose and of the two low-gelatine gels in
dextrose. It may be that the two high-gelatine
gels also swell less in 50 per cent. dextrose but
the decrease is not certainly determinable
from the single test which was made. This
decrease in swelling in concentrated sugar
solutions is to be expected from analogy with
the osmotic behavior of such solutions and
does not indicate any specific effect of either
sugar on the swelling or imbibition capacity
of the gels themselves.

A new'method of separating zinc from cadmium
and the latter’s determination todometrically:
Eric JOHN Ericson. The separation consists in
erystallizing the zine out as zine sulphate or zine
ammonium sulphate. It may be applied to the de-
termination of cadmium in ore or in spelter (after
Temoving and determining lead). In the latter
ease, although a small trace of cadmium is en-
trained in the crystals, only one crystallization is
deemed necessary in view of the large sample
taken. After removal of zine, the cadmium may be
determined by any of the usual methods. An
iodometric method is outlined.
The determination of cadmium in brass: E.
ScuramMM. Owing to the lack of any well-tried
SCIENCE
143
method for the determination of cadmium in brass,
a series of analyses was carried out on brasses and
on mixtures of salts with and without additions of
cadmium. A procedure was developed which gives
fairly reliable results for the small amounts of
cadmium concerned. The method consists essen-
tially in removal of the copper electrolytically from
nitric acid solution, followed by separation of the
cadmium from zine with hydrogen sulphide, in so-
lutions of regulated acidity and small volume.
The cadmium is finally weighed as sulphate.
The electrometric titration of zinc: F. RussELL
v. BicHowsky. In the potassium ferrocyanide
method for determining zine there are three prin-
cipal sources of error: (1) Oxidation of the ferro-
eyanide by any nitric acid, chlorine, or bromine
present; (2) precipitation of other metals along
with zine; (3) uncertainty of the end point. To
remove the first source of error precautions such as
the addition of SO, should be taken. To avoid the
precipitation of other metals the rational proced-
ure is to change the conditions of the ferrocyanide
precipitation by carrying it out in solutions con-
taining from 10 to 20 per cent. HCl. In these solu-
tions zine ferrocyanide is only slightly soluble, but
lead, manganese, iron and copper ferrocyanides
are very soluble. Since the ordinary indicators can
not be used at this concentration of acid, an elec-
trometrie determination of the end point is
adopted, which is found to be quicker and more
accurate than the older methods. This consists in
noting the point at which there is a sharp change
in potential of the solutions against a platinum
electrode. The apparatus is the same as that used
in determining the end-point of oxidation and re-
duction reactions in the analysis of iron, vanadium,
ehromium, ete. Experiments on a number of salt
mixtures show that the end point is not affected
by the amount of acid or neutral salts present
within reasonable limits, nor by the presence of
iron, lead, manganese (up to 50 mg.), or by small
amounts of copper and cadmium. The preliminary
operations for the purification of the ore therefore
lose their customary importance; comparative re-
sults show that the electrometric method is more
rapid than the usual procedure.
The vapor pressure of zine and related metals:
JoHN JOHNSTON. A review of the somewhat scat-
tered observations on the vapor pressure of high-:
boiling metals, and a reduction of the data yield-
ing equations by means of which the vapor pressure
at any temperature can be ascertained. Published
observations on the volatility of metals, alone and
from mixtures, are also summarized.

The new zine fields of Kansas and Oklahoma: W.
P. Haynes. A visit to the new zine fields south of
Baxter Springs, Kansas, and to Picher and Ad-
miralty, Oklahoma, shows the great strides in pro-
duction which this district is making. Small drill-
ing rigs dotting the prairie mark the advance
guard, prospecting to determine the value and ex-
tent of the ore bodies. Concentrating mills follow
closely and give the appearance of a large city.
The ore minerals in this new district are chiefly
sphalerite with some galena and variable amounts
of pyrite and marcosite. This ore is much richer
than in the older Galena-Joplin district and fre-
quently contains over 20 per cent. of sphalerite.
The origin of the ores of this district is still some-
what in doubt, but the most recent researches by
Siebenthal have led him to conclude that they have
been produced from the disseminated sulphide min-
erals scattered through the Cambro-Ordovician
limestones, by artesian waters transporting them
in solution and ascending and depositing them in
the open spaces of the cherty members (Grand
Falls chert) of the Boone formation (Burlington
or Mississipian limestone), which is the productive
horizon in this region.
Recent investigations on the smelter smoke prob-
lem: A. E. Weuts. At most smelters where large
quantities of sulphide ores are being handled, seri-
ous efforts are being made to utilize through the
manufacture of sulphuric acid, liquid dioxide or
elemental sulphur, the sulphur dioxide which re-
sults from the roasting and smelting of these ores.
However, at plants situated at a considerable dis-
tance from markets for these products, only a
comparatively small amount of the sulphur can be
so utilized. It is recognized that although the
amount of the smelter waste sulphur gases that
will be utilized in commercial products will be in-
creased steadily, yet, for many years to come,
these smelters will be obliged to waste large vol-
umes of sulphur dioxide daily into the atmosphere.
Therefore, efforts are being made to determine
how, under different climatie and topographic con-
ditions, these large volumes of sulphur dioxide can
be discharged into the atmosphere without doing
injury to vegetation in the surrounding country.
In this paper the development of the methods for
conducting these investigations were discussed
briefly.
Notes upon the hydro-metallurgical and electro-
lytic treatment of zine ore: E. E. Warts. After
briefly discussing the treatment of zine ore, the
SCIENCE
[N. 8S. Von. XLVI. No. 1180
paper related the writer’s experimental work upon
the ore of the Sullivan Mine of Kimberly, B. C.
This work served to develop a process that involved
a sulphurous acid leaching of the ore, and further
experimental work developed the Watts Process.
By this process, zine oxide obtained by any suit-
able means is treated in specially constructed
electrolytic tanks for the recovery of zine. The
work done in the experimental plant of the Electro
Zine Company at Welland, Ont., was discussed.
Chemical examination of industrial brines: O. R.
SWEENEY and James R. WitHrow. The value of
chemical examination, from the manufacturer’s
standpoint, was discussed. The errors resulting
from improper sampling were shown, and a sugges-
tion for a standard method given. The constituents
which it was thought should be determined were
given; together with the form in which they should
be reported. A standard procedure for determin-
ing the density was given and the best. tempera-
ture to use was discussed. Suggestions for deter-
mining total solids from the author’s experiences
were given. Procedures for silica, iron and
aluminum were given and shorter methods for eal-
cium and magnesium in mineral waters. Barium,
strontium, sodium, potassium and sulfuric acid
procedures were given, also modifications of the
methods for bromine determination.
Contribution to the industrial chemistry of
chicle and chewing gum: FREDERIC DANNERTH.
The author presents methods for the valuation of
commercial block chicle by determining moisture,
viscosity, resins, proteins and carbohydrates and
mineral matter. Twenty problems relating to the
chewing gum industry are presented. The total
exports of finished chewing gum, amounted in
1916 to $574,400, equivalent to approximately
718,000 pounds. This represents crude chicle
equal to at least 179,000 pounds. The amount of
chicle imported, manufactured and consumed in
the United States in 1916 was approximately
7,031,000 pounds equivalent to 28,124,000 pounds
of chewing gum. Researches are at present being
carried out on the constituent elements of chicle—
alpha chicl-alban; beta chicl-alban; gamma chicl-
alban; chicl-fluavil, and chicl-gutta. These sub-
stances have been investigated by Tschirsch and
later by Bosz and Cohen. The latter investigators
have not entirely agreed with the results published
by Tschirsch.
Apparatus for determining the specific gravity of
natural gas; Cuas. K. Francis. The apparatus
is to be used according to the method proposed by
AveusT 10, 1917]
Bunsen, which is based on the fact that the specific
gravity of two gases bear approximately the same
ratios to each other as do the squares of their rate
of flow when passing through a very small open-
ing. The apparatus consists of a pipette or burette
to which is sealed at right angles, just below the
tip, a glass stopeock. To the tip of the burette
another stopeock is sealed which is provided with a
very small, practically invisible opening. The gas
to be examined is admitted through the larger side
opening and the time of escape is measured
through the small opening. A sample of air is
measured in the same manner. The following ex-
ample will serve as an illustration: The time re-
quired for the sample of gas to escape was 13.4
seconds and for the same quantity of air, 11.8 sec-
onds; these squared are equal to 190.4 and 129.9.
As the specific gravity of natural gas is referred
to air as unity, the specific gravity is obtained by
dividing 129.9 by 179.5=0.723 the specifie gray-
ity of the gas.

type with a capacity of 4,000 liters was brought
from Germany in 1914 and a wooden open tub of
the same capacity was constructed. Eleven experi-
ments were made, fermenting simultaneously mash
from the same batch in both vessels. The results
obtained were in favor of the closed fermenter,
viz., lower acidity in the finished beer, and in-
creased yield, amounting to one per cent. of spirit.
The yields from the open fermenter corresponded
‘to the average yields obtained in the ordinary nor-
mal runs of the distillery.
The effects of exposure of some fluid bitumens:
CHARLES 8. REEVE and RicHarp H. Lewis. The
work described was a continuation of that begun
by Hubbard and Reeve (Jour. of Indus. and Eng.
Chem., 1913), and of later results published by
Reeve and Anderton in the Journal of the Frank-
lin Institute, October, 1916. Experiments were
earried out along similar lines to those previously
followed, using fluid types of products which had
not been previously investigated. Exposure tests
conducted for a period of one year show that cer-
tain types of petroleum harden materially while
others are relatively little changed in their phys-
ieal character, although all are materially changed
in their composition as shown by the change in
percentage of bitumen insoluble in naphtha and
free and fixed carbon values. The relation be-
tween amounts volatilized upon heating for vari-
ous periods in a laboratory oven at 163° C. and the
SCIENCE
145
amounts lost upon atmospherie exposure were
shown by tables, and relations between the charac-
ters of the residues obtained by the two methods
of volatilization were given, As in the previous
work referred to, the changes which occur in bi-
tumens upon exposure are notably greater than can
be accounted for by mere loss of volatile constitu-
ents, and are due to chemical changes in the con-
stitution of the bitumen itself.
The thermal and pressure decomposition of an
absorbent oil: Gustav Eciorr. An absorbent oil
derived from a Pennsylvania crude petroleum,
specific gravity 0.828/15.5° C. and 95.3 per cent.
boiling between 250° C. and 350° C. was subjected
to temperature conditions of 550° C., 600° ©. and
650° C. in the gas phase at one and eleven at-
mospheres pressure. The above conditions of tem-
perature and pressure gave the following per-
centages of gasoline, benzene, toluene and zylenes
on basis of oil used.

The formation of benzene and toluene by the ac-
tion of aluminum chloride on solvent naphtha:
Gustav Ecutorr. Solvent naphtha derived from
the thermal decomposition of coal, having a spe-
cifie gravity of 0.867/15.5° C. and 93 per cent. dis-
tilling between 135° and 160° C. with the dry
point at 181° C. was treated with anhydrous
aluminum chloride. Five per cent. by weight of
AICl,, was added to one liter of solvent naphtha
and distilled over in two hours from a Hempel
flask until 78 per cent. came over. The distillate
was neutralized with caustic, washed and dried
over calcium chloride. The distillate upon analysis
gave on the basis of solvent naphtha used 1.2 per
cent. of benzene and 13.9 per cent. of toluene.
The determination of available oxygen in ozi-
dized manganese ores: O. L. BARNEBEY. The
oxalic acid method is in common use in America
for the determination of available oxygen in oxi-
dized manganese ores and hence is the basis for the
evaluation of such ores for certain industrial pur-
poses. This method gives inconsistent results
causing much difficulty in control work involving
the use of pyrolusite and similar products. The
146
method is shown to be highly empirical, the errors
being produced by decomposition of the oxalic
acid by the action of the light in the presence of
manganese salts. A modified ferrous sulfate
method is accurate and is recommended for fac-
tory control work. The latter method gives re-
sults in close agreement with results obtained by
Bunsen’s distillation. method and a new direct
iodimetric method worked out by the author.
Some relations of the effect of over-heating to
certain physical and chemical properties of as-
phalts: A. W. Hixson and Haro~p HE. Hanps. An
oil asphaltic cement, a brick filler fluxed with an
asphaltic oil residuum and a crude Trinidad
asphalt were heated to various temperatures be-
tween 163° C. and 350° C. under uniform condi-
tions. Physical and chemical analyses were made
on the products of the various heatings. The re-
sults show that heating asphalts above certain
temperatures change both the physical and chem-
ical properties. The carbene content was not
changed materially until the temperature of heat-
ing was above 200° C. Above that temperature
there was a decided increase in carbenes. The re-
sults seem to indicate that carbenes are the result
of cracking parafiine and asphaltic hydrocarbons
into napthenes and unsaturated hydrocarbons.
Moderate heating may so change the nature of the
asphalts as to render them more soluble in carbon
tetrachloride than in carbon disulphide. Over-
heating causes marked changes in natural and oil
asphalts which render them unfit for many struc-
tural purposes. Two hundred and thirty-five de-
grees Centigrade is probably the maximum tem-
perature to which an asphalt may be heated with-
out permanent injuries to its useful properties and
for certain structural purposes they should not be
heated above 200° C. It is believed that the fixed
carbon content when corrected to the original
weight before heating offers a means of tracing
the changes in the molecular structure of the hy-
drocarbons when they are subjected to the influ-
ence of heat. There is a close relation between
the carbene value and the physical and chemical
properties of asphaltic materials. The carbene
specification is important for asphaltic materials
for construction purposes.
Chemical Industry in Canada: H. E. Howe.
The paper outlined something of the chemical in-
dustry in Canada, with special reference to recent
important developments and new processes which
have been perfected under the stimulating influ-
ence of war conditions, but which will become im-
portant factors in the chemical business after the

war. It also recounted something of the natural
resources of Canada as indicating the raw mate-
rials upon which chemical processes and industries
may eventually be based, coneluding with the state-
ment of the steps that are being taken by private
corporations, educational institutions and the gov-
ernment to apply scientific and industrial research
looking toward the more economic utilization of
natural resources and the establishment of chem-
ical industries to serve a population which will
undoubtedly increase at an abnormal rate follow-
ing the declaration of peace.
The availability of nitrogen in fertilizers. A
new method based on the nitrogen rendered water-
soluble by incubation with a fertile soil: J. P.
SCHROEDER. Theoretical and practical considera-
tions governing the availability of substances for
plant nutrition in recent researches dealing with
the assimilation of various forms of nitrogen and
the merits of various methods for determining
availability were discussed. A proposed method
consists of incubating a small sample of fertilizer
with a 100 gm. portion of fertile soil at 30° C.,
maintained just below its critical moisture con-
tent and determining the total nitrogen that has
been converted into the water-soluble form. It
differs from the nitrification method and the am-
monification method in that it takes into considera-
tion both of those forms of nitrogen; also that in
the form of nitrites and soluble protein compounds,
all of which are assumed to be available or readily
convertible into available form. It makes pos-
sible a shorter incubation period than in the nitri-
fication method and the use of the exact ammonia
determination instead of the difficult nitrate esti-
mation.
The fertilizer value of city wastes—II., garbage
tankage: J. P. SCHROEDER. The origin and compo-
sition and principal methods of rendering garbage
were briefly outlined. Complete analyses of twenty
samples of garbage tankage, representing all the
larger garbage reduction plants in operation in
this country, show on the average 3.3 per cent. am-
monia, 7.84 per cent. bone phosphate and 0.80 per
cent. potash, after removal of the oil, which usually
amounts to about 12 per cent, Calculations based
on these analyses and on figures showing produc-
tion in cities of 50,000 and over, call attention to
the large source of ammonia available. The availa-
bility of this ammonia for plant use is shown by
experiments with different methods, and the gen-
eral applicability of the material for fertilizer pur-
poses based on its physical and chemical proper-
ties was discussed.

most popular size, but the larger sizes are also in great de-
mand up to the No. 140 which is the largest regular size, be-
ing 32”x18"x24”. The regular ovens are intended for tem-
peratures up to 180°C. The special High Temp ovens, how-
ever, are intended for temperatures up to 260°C. The High
Temp ovens are used especially for asphalt and oil tests, also
for baking tests and in general wherever a known uniform
high temperature is required. The regular ovens are used
for a great variety of moisture tests. For organic tests es-
pecially in connection with foods, colloids, etc., the Freas
Vacuum oven is ordinarily employed. All of these ovens
maintain uniform temperatures to within a degree.
Special Advantages of
Freas Ovens |
No expense is spared in construction, the aim being to
make the ovens as nearly perfect as possible.
The oyens are so thoroughly insulated that losses of heat
by radiation are almost entirely eliminated. For this
reason these ovens require only about one half as much
current as is required by other styles of ovens. The rela-
tively small amount of current required implies corres-
pondingly less strain on the wiring, less danger of spark-
ing, and in general longer and more satisfactory service.

THE FUTURE OF THE SIGMA XI1
In a few weeks it will be thirty-one
years since some students of Cornell Uni-
versity, feeling the injustice of the old-
fashioned kind of education that gave all
its honors, all its encouragement to the
students of the liberal arts, planned an
honor society in the sciences. They
thought, as most of us now think, that
not all of good was confined to Latin and
Greek, that there was also merit in the nat-
ural sciences, that the student of geology
or of engineering was as deserving of hon-
ors and of encouragement as the student of
the classics. As they walked home from
the commencement where the honors of Phi
Beta Kappa had been liberally bestowed,
they conceived a society that would recog-
nize in an equal way the merits of the
bachelor of science. And the Sigma Xi
was born.
But higher education in America, as in all
nations, has developed much since those
days, and that exponent of the liberal ed-
ucation of those days has also changed.
The Sigma Xi of 1886 would find little en-
couragement in most of our universities
to-day, and we of the Sigma Xi may justly
claim some of the credit for that change.
The classical education of fifty years ago
has but few proponents to-day, for science
is now recognized as an essential part of
any liberal education.
Perhaps some of us are claiming too much
for science in education ; I half believe that
we are. When I received my bachelor de-
gree, a good many years ago, my commence-
ment speech was a diatribe on Latin and
1An address delivered to the initiates of the
Yale chapter of the Sigma Xi, April 2, 1917.
148
Greek, which had exacted a full half of all
my college work. But, I have frankly to
admit that my debt to them is great, great
because the science of those days was not a
substitute for them, nor am I fully con--
vinced that it yet is.
The Sigma Xi was founded, we may
frankly admit, merely as a rival for the
Phi Beta Kappa—perhaps there was a
flavor of sour grapes in its origin! Has
it justified its past? Is there justification
for it to-day, and need for it in the future?
Without reservation the answer to all these
is yes. But, for the Sigma Xi of 1886
the need was brief. Science has won recog-
nition as an essential part, though not the
whole part of any liberal education. There
was a time, not so very long ago, when
studies of immediate bread-and-butter in-
terest were debarred from the curriculum
for the bachelor of arts degree as contam-
inators of a liberal education. JI can re-
member a long and warm discussion in one
of our large universities as to whether the
study of human anatomy might safely be
substituted for that of cat anatomy; not
because the study of man was less worthy
than the study of cats, but because the one
was pursued for a practical purpose while
the other was merely disciplinary. My col-
leagues of the language side feared that it
would be, as indeed it was, a wedge to make
education practical as well as cultural.
Similar discussions are not often heard now
in our faculty meetings. To preserve the
degree of bachelor of arts in all its pristine
aristocratic purity, the degrees of bachelor
of science and of philosophy, and of I know
not what else, were widely introduced for
the proletariat in science. For a long time
they were the penumbra of classical learn-
ing, and even yet in some places they have
not won their full place in the sun. I hope
that the time will soon be here when there
shall be no distinctions anywhere between
SCIENCE
[N. S. Vou. XLVI. No. 1181
the student of Greek and the student of
botany or chemistry, or of psychology.
One is as useful in its way as the others,
and has an equal place in liberal educa-
tion, but not to the exclusion of others.
This is now so evident that the statement
would be a mere platitude, were it not that
the Sigma Xi was founded expressly to
help break down the distinction.
The Sigma Xi has long since ceased to
look exclusively upon the other side of the
Phi Beta Kappa shield. The ideals of our
society are not those of its founders thirty
years ago, when the simple recognition and
encouragement of scientific studies were
the most that it could do. Its higher ideal
is now, as it has been for years, I can say
with your unanimous approbation, the en-
couragement of productive scientific schol-
arship. The encouragement of scientific
scholarship is but a part of its function.
The student who, when he dons for the first
time his academic gown, is able to talk
learnedly of what his text-books and teach-
ers have taught him about chromosomes,
the mutations of @nothera, dominant and
recessive characters, the location of Cam-
brian rocks, the secret history of trilobites
and dinosaurs, or the mysteries of ions and
organic compounds, is a worthy candidate
for membership with us, but he has not
justified his right to full fellowship with
the Spoudon Xunones until he has given
evidence of his ability and desire to use
that knowledge for the benefit of science.
Our ultimate ideal, then, in a few words,
is the encouragement of research. And the
student may properly ask, what do you
mean by research?
The word is something of a fetish with
us. Is counting the number of feathers in
a bird’s wing, or the hairs in a mosquito’s
antenna research. Yes, if it leads the stu-
dent better to understand the structure of
all birds and all flies. Otherwise it might
Aveust 17, 1917]
as well be done by a properly constructed
machine. We have been told that the mere
accumulation of simple scientific facts
never makes a leader in science, that, for
instance, the collection of birds and bugs
and brachiopods and their discrimination
into species and subspecies is an inferior
kind of research in natural history. But,
every scientific man of repute in the past or
present has begun in just that way, by the
discovery and discrimination of scientific
facts, however simple they may appear to
others. Lamarck was a mere collector and
namer of mollusks; Charles Darwin wasted
years of his brilliant life in classifying cir-
riped crustaceans—I wonder how much
those cirripeds had to do with natural se-
lection, and I wonder how many of us
would know a ecirriped if we should meet
one? Agassiz gave years of his life to the
collection and study of poissons fossiles,
and it requires no more acumen to classify
fossil fishes than living bugs, for I have
tried both. The collection and discrimina-
tion of mosquitoes was once a puerile pur-
suit. But, had there been no collectors and
classifiers of mosquitoes, yellow fever would
still be ravaging our seaports, and perhaps
the Panama Canal would not now be a real-
ity, and the safety of our nation endangered.
Can any one see any possible relation be-
tween a mere entomological collector and
the destruction of great cities by war?
Had not Loewenhoek, in mere curiosity,
found those organisms we call bacteria, and
others wasted their time in studying and
classifying them, there would have been no
Pasteur, and antitoxins unknown. Is there
no relation between such trivial pursuits, as
some of our friends would call them, and
typhoid fever?
I say, and say with deep conviction, that
the ability displayed in the observation
and discrimination of what often appear to
us to be trivial things may be as great as
that required for the formulation of far-

reaching laws in science. Even the tyro
can draw conclusions, that is, recognize
laws, when facts are numerous enough, and
the best of us can do nothing without facts.
And the discovery of natural laws is sure to
come when facts are numerous enough. It
is the trained student who anticipates them.
How many great discoveries or great inven-
tions have uncontested claimants? Who
was the discoverer of electricity, photog-
raphy, telegraphy, telephony, aviation, or
even evolution ?
Let us not, then, deride the student be-
cause he is doing what we in our conceit
think is unimportant. There are fashions
in science as in everything else, and we are
rather inclined to ridicule him who is not
quite up to fashion. Shall we tell the candi-
date for honors in Sigma Xi that he must
be in fashion? That research is research
only when it leads to worldly recognition?
No, train him aright, and nothing will be
too trivial to merit his study. It is not
what he does but how he does it that makes
the leader in science as in everything else,
for there is nothing small in science.
One of our noted chemists, not long ago,
I have been told, after the publication of an
important paper, when asked by the presi-
dent of his college of what use his discover-
ies were to the world, replied that he hoped
they had none. We would not wholly agree
with him, because the ultimate end of all
our research is the benefit of mankind, and
there surely must be some practical use of
every fact in science. He did emphasize,
however, the first essential of every true
scientist, the desire to learn new truths for
the sake of truth.
Research ability I would define as the
ability to observe, to discriminate, and to
judge, coupled with an intelligence that is
always asking the reason why. Given this
ability to observe and to understand, and
its possessor has the foundation for suc-
cess, whether in science, in arts or in the
150
everyday affairs of life. Every day life is
but a continual round of original research
for every successful physician, lawyer,
statesman or business man. And this is the
highest aim of our society, to encourage the
training of such students. As teachers our
pupils look to us for inspiration and he
only can give inspiration who knows the
joy of research himself.
As a society for the mere giving of hon-
ors for scientific scholarship we have out-
erown our past, and indeed that was our
function only for a brief time. But we still
have a duty to encourage scholarship, for
without scholarship there can be no re-
search. It is human nature to seek honors.
Scientific men, like all others, from the
humblest to the greatest, welcome them,
whether it be membership in the Sigma Xi
or in the National Academy of Sciences.
When honors come as rewards for meri-
torious work accomplished they cheer and
encourage; and they stimulate ourselves
and others to higher efforts. We would not,
if we could, abolish honors for scholarship
from our society, we would not restrict
them to accomplished research.
And our colleges and our nation need us
for the higher work; never was there
greater need for the work we can do, and
these dangerous days are impressing us
with that need. Until the millenium comes
when we shall all live in peace and har-
mony, and like the dinosaurs grow big, fat
and vulnerable and like them become ex-
tinct, the nation will need the utmost we
can do in science.
Ts it merely a coincidence that the life of
the Sigma Xi has been nearly synchronous
with the marvelous development of science
in America? When this society was born
there were but a few score of noted research
men in science, and but one or two special
societies in science. Now we number our
alumni by the thousands, active research
men by the hundreds, and scientific so-
: SCIENCE
[N. 8. Vou. XLVI. No. 1181
cieties by the score. Then it was necessary
for young men who would do things in sci-
ence to go abroad, and chiefly to Germany,
for their training. Who is there now who
finds it necessary to go abroad for lack of
suitable instruction here? It was not many
years ago that I heard the justly famous
Dr. Koch, of Germany, say that America
was becoming the leader in medical educa-
tion and that soon it would be necessary
for foreign students to come here for their
best training. We have been told so many
times by our scientific friends abroad that
we are precocious but still undeveloped in
science that we have been inclined to be-
lieve them. But that time has passed. I
say, not in boastfulness, but in conscious
truth, that to-day America is doing more
research work in nearly every branch of
pure science than any other nation upon
the globe. And the quality of our work
suffers not in comparison. I have grown a
little weary of the common assumption that
we are still looking across the water for our
inspiration and guidance in scientific re-
search.
We are doing more work, we are doing
quite as good work in pure science, not be-
cause we are any abler or better than other
people, and especially Germany, but because
ours is a democratic nation that gives to
every one opportunity and stimulus; be-
cause we are less bound by precedent, be-
cause the teachers of our colleges and uni-
versities are less creatures of control. In
Frankfurt-on-the-Main I was told, a few
years ago, that the national government
would not permit the privately endowed
university they were founding there to ap-
point its own faculty. It reserved the
privilege of making every professor a crea-
ture of the controlling government. Fancy
what our progress would have been in
America had a self-perpetuating cabinet of
the national government had the power to
Aveust 17, 1917]
nominate every teacher in every college of
our land!
These are some of the reasons, I am sure,
for our remarkable development in pure
science during the past forty years, some of
the reasons why we may look forward to
still greater progress in the coming years.
Has our society had no part in this prog-
ress? Shall its part in the future be
greater, or less? Do our colleges and uni-
versities still have need of us to strengthen,
to sustain ?
In one great side of science, however, for
which our society stands, we, as a nation,
have failed as compared with others, and
especially Germany. Applied science, I
mean, or at least some branches of it. Eng-
land is awakening to its negligence in the
past ; never in the history of the empire has
the scientific man of Britain been more ap-
preciated than he is at present. And there
is a new epoch for America coming soon.
We have our Langleys, our Maxims, our
Bells, Edisons and Wrights of whom we are
proud, but our colleges have not had much
share in their production, and we in the
pure sciences are still a little inclined to
look askance at them as the antithesis of
that supposed ideal of our famous chemist.
Has the Sigma Xi done all that it should
in the past to encourage the applied sci-
ences? Shall we give greater encourage-
ment to the student who counts the bristles
in a mosquito’s proboscis or the plasmodia
in its stomach than to him who applies that
knowledge to the prevention of yellow
fever? Does it require less ability, less re-
search to observe, to discriminate, to judge
in the construction of an airplane or a talk-
ing machine than to trace the fibers of a
cerebral ganglion, or reconstruct the back-
bone of a dinosaur? Have we done what
we should? Or shall we frankly restrict
ourselves to the encouragement of research
in pure science and leave its application
for others to further, to encourage? I be-

lieve that the decision is now before us, and
upon our answer depends much of the fu-
ture of our society. Trained as a young
man in two professions of applied science,
and the most of my life given to research
in science so pure that its application to
things practical seems remote in the ex-
treme, perhaps my sympathies with both
are more pronounced than usual. I can see
no difference in the quality of research that
I gave to locating a railroad line, the treat-
ment of a patient with measles, or the re-
construction of a paleozoic reptile. It
would be a misfortune for us, I earnestly
believe, to restrict ourselves to the encour-
agement of research in pure science.
A great future, I am sure, for science in
America is its application, and the greater
efficiency we reach in making use of the
many discoveries of pure science for the
amelioration and improvement of our con-
ditions as a nation, the higher will be the
honors, the greater encouragement we shall
receive in the discovery of new facts and
of new laws; the more honorable, the more
appreciated will be the profession of the
research student in pure science.
Because we as a society have not done all
that I think we should have done in the
encouragement of the applied sciences, nu-
merous rival societies in our technological
schools have come into existence. We are
all working for the same objects, why
should our efforts be weakened by rivalries?
Why should we not all be united in a single
great organization for the promotion of all
branches and sides of science? I feel sure
that the greater extension and the greater
usefulness of the Sigma Xi has been hamp-
ered by our lack of accord in our ideals.
Some of our chapters grant membership
almost wholly for high scholarship, others
exclusively to graduate students who have
accomplished or are accomplishing meri-
torious research work. And this lack of
unanimity has prevented, I am sure, the
152
greater extension of the society. We have
but thirty chapters, an increase of but ten
in the past ten years or more. There are at
least a hundred institutions in America
that need such encouragement as we can
give. We have hesitated to extend our so-
ciety, not because we are aristocratic, but
because we earnestly desire to keep its
ideals high, and know no way by which to
ensure their preservation.
A step has been taken, one that I have
hoped for for years, to define more pre-
cisely our ideals that we may entrust them
fearlessly and safely to every institution
where a few of us are gathered together.
And I am still further encouraged to be-
lieve that in the end, even though it be
slowly, it will lead to the results I have
long hoped for, the extension of our society
throughout our nation. Other organizations
are doing much for the promotion of scien-
tific research; ours is the nobler duty to
train men and women for research in sci-
ence, both pure and applied, to sustain, to
encourage the university in the develop-
ment of the science of the nation. Yale has
done very much in the past, I am sure it
will take its full part in the advancement
of the future. Its ideals have always been
high and they have been reflected in the
chapter of the Sigma Xi. I can say with
assurance that in no chapter of the society
is the honor of election to membership
greater. } :
In conclusion, I would say a few words
to the initiates of this evening. You have
pledged yourselves to uphold and sustain
the ideals of the Sigma Xi. An honorable,
a useful future lies before you. The world
needs you as it has never needed such men
as you before. Your vocation in life is
more honorable than it ever has been be-
fore in the estimation of the world. I am
sure that when you shall have reached my
age, science will have won far greater hon-
ors yet for its earnest and sincere devotees,

even as it has changed marvelously since
the time when I was as young as you are.
New facts and new laws awaiting your
discovery are as numerous as ever. Your
work may be greater, but you are equipped
to do that work more easily than we were a
score or two years ago; your footsteps will
be more direct, and the harvest that awaits
your reaping is very, very great. And I
would encourage you with the assurance
that, no matter how humble that work may
seem to you, if you have learned rightly to
observe, to discriminate, and above all, to
judge, there are no limits but your energy
and your ambition to the heights you may
climb. SamMuEL W. WILLISTON
UNIVERSITY OF CHICAGO
THE WORK OF DEAN H. L. RUSSELL
During commencement week his colleagues,
friends and former students celebrated the
twenty-fifth anniversary of the doctorate of
H. L. Russell, dean of the College of Agri-
culture of the University of Wisconsin. In
1892 Johns Hopkins University honored Pro-
fessor Russell by conferring this degree upon
him. This year (1917) also marks the com-
pletion of twenty-four years of service to the
University of Wisconsin. The last ten years
of this period have been occupied in directing
the activities of the College of Agriculture
and the Experiment Station.
At the anniversary last week bound records
of the results of the work accomplished by
Dean Russell were presented to him. Three
sturdy volumes there were—nearly two thou-
sand pages.
“What Dean Russell has meant to Wis-
consin and her farmers purely as an invest-
ment cannot be estimated, so extensive have
been his activities and so far-reaching their
results,” said E. G. Hastings, professor of bac-
teriology, in speaking of the relation of Dean
Russell’s work to Wisconsin and her farming
industry. Professor Hastings has been closely
associated with Dr. Russell in his work as a
bacteriologist, having worked with him when
he was head of the department of bacteriology
Aveust 17, 1917]
and becoming head himself when the position
was vacated by Dr. Russell. Professor Hast-
ings said:
At the time Dean Russell was graduated from
the University of Wisconsin in 1888, bacteriology
was just being developed at the university. The
history of what bacteriology has done for the con-
trol of many animal diseases, such as hog cholera,
anthrax, black leg and bovine tubereulosis—dis-
eases which formerly killed off thousands of head
of live stock annually; of what it has done for the
production of milk and the consequent lowering of
the nation’s death rate, especially among infants;
of what it has done for the control of plant dis-
eases, thereby saving millions of dollars to the
country annually by increased crop production; of
how the cheese industry has grown with increasing
knowledge of bacteria, of what has been learned
about the power of nitrogen-fixing bacteria, to en-
rich the soil and thus inerease the crop yields, of
how it has brought about improved sanitary con-
ditions, and how it has helped with the canning in-
dustry and the preservation of food by other meth-
ods—the history of all this, which is the history of
agricultural bacteriology during the past twenty-
five years, speaks for the wisdom of spending
money and time on the study of bacteriology in
any state, and especially in a state with the dairy
and erop record of Wisconsin.
The introduction of bacteriology at the Univer-
sity of Wisconsin was due to the efforts of Dr. Wm.
Trelease, now of the University of Illinois, and to
Dr. E. A. Birge, dean of the College of Letters and
Science of the University of Wisconsin. The first
announcement of courses in this subject was con-
tained in the university catalogue issued in 1887—
1888. It may seem strange that even before the
science of ‘‘bacteriology’’ had received its name,
it had found a place at this then far-western insti-
tution. This was due to the fact that those per-
sons in charge of the university were men with
the spirit of the pioneer. A pioneer must be a
progressive man, a man who is always on the job,
aman of good judgment as to the road to follow.
Such men Wisconsin had.
Dean Russell became interested in bacteriology
early in his career as a student, and under the in-
fluence of his teacher, Dr. Birge, he decided to go
to Europe for instruction under the masters of
what was then a comparatively new subject. He
studied at Berlin while Robert Koch, the great
pioneer of medical bacteriology, was actively en-
gaged in teaching and investigating, and at Paris
while Louis Pasteur was still busy in his labora-
SCIENCE
153
tory. He returned to America and spent one year
under Dr, William Welch of the Johns Hopkins
University, thus completing the eighth year of his
preparation for work—a long time in getting ready
to work but the wisdom of this is shown in the
things accomplished in the next twenty-five years.
About this time, in northern Germany and Den-
mark, the relation of bacteria to dairying, espe-
cially to the manufacture of butter and cheese, was
beginning to attract attention. W. A. Henry, then
dean of the College of Agriculture, with true
pioneer spirit, realized that Wisconsin was destined
to be a great dairy state if matters were rightly
directed; it had great natural resources in lands, in
climate and in men—for it had within its borders
such men as Governor W. D. Hoard and Hiram
Smith. Dean Henry’s task was to make his insti-
tution do its share in the development of this in-
dustry. Looking back upon his work from the
present day, no one can question his success,
Dean Henry decided that dairy bacteriology was
something he must introduce in the work of the
experiment and the college. It was most natural
that his attention should be directed to the first
student of the university to adopt it as a life
work. Dean Russell came to the College of Agri-
culture in 1893, and immediately began work on
the relation of bacteria to dairying and to bovine
tuberculosis. The tuberculin test was just being
introduced into this country, the Experiment Sta-
tion herd being the first one west of the Alle-
ghenies to be thus examined. This test revealed a
sorry state of affairs; twenty-five out of thirty
animals were found diseased. The herd was
slaughtered. The new herd, which was assembled
has been kept practically free from tuberculosis
for twenty years. Animals have been introduced
that later have reacted to the test, but the consist-
ent and persistent use of the test has prevented
any spread in the herd. True, expense has been
involved in this work, but returns have been
brought, both in money to the state and satisfac-
tion to those in charge of the herd. Back in 1894,
if the breeders of Wisconsin had adopted the ad-
vice given in Bulletin 40 of this station published
that year, the state would have been in a far more
enviable position as far as tuberculosis goes than
at present.
' Another subject which received much attention
and which has accomplished an endless amount of
good, was the study of the contamination of milk
—the sources of such contamination and its pre-
vention. The work done in pasteurization of milk
outlined the method which is used so widely at the
154
present time for the treatment of market milk, a
method that was not actually put into practice
until ten or more years later because the industry
was not ready for it. It is certain that the credit
that should be given Dean Russell for his work on
pasteurization of milk has not been bestowed be-
cause it came at too early a period in the develop-
ment of the industry.
Various other fields of farming investigation
have engaged Dean Russell’s attention, including
the study of bacterial diseases of plants, especially
the black rot of cabbage. One of the lines of
effort in which study of bacteriology has yielded
results of great practical value was the relation of
bacteria to the ripening of cheddar cheese. The
discovery that cheese could be ripened at much
lower temperatures than was previously thought
possible was a by-product of scientifie work, a
by-product that adds hundreds of thousands of
dollars to the income of the cheese industry in
Wisconsin yearly, and will do so as long as cheese
is made.
The state of Wisconsin has invested much money
in work that has been accomplished by Dean Rus-
sell during these twenty-four years of service as a
bacteriologist and director of the work of the Col-
lege of Agriculture and Experiment Station. The
question of importance to-day is the soundness of
the investment and the returns it brings. Those
who are best acquainted with the matter would
cease to worry about the high cost of living and
of dying if they could feel that their investments
were one half as sound and would bring them one
thousandth part of the returns that the state of
Wisconsin receives from the money it has invested
in this man,
THE PRIESTLEY MEMORIAL OF THE
AMERICAN CHEMICAL SOCIETY
By resolution of the council of the Amer-
ican Chemical Society adopted at its meeting
in Urbana in April, 1916, the president was
requested to appoint a committee to devise
and earry out a plan for a suitable memorial
to Joseph Priestley. After careful consider-
ation of various plans, the members of the
committee desire to present the following
recommendations to the Society:
1. That a bust portrait of Joseph Preistley
be secured, to be a copy of the best available
portrait; that this be retained as the property
of the American Chemical Society, but be de-
SCIENCE
[N. 8. Vou. XLVI. No. 1181
posited as a loan in the National Museum in
Washington. Also,
9. That a gold medal be awarded at inter-
vals of probably more than one year for supe-
rior achievement in chemical research; the
award to carry with it the requirement that
the recipient shall deliver an address before
the general meeting of the society at the time
of the presentation or at such other time and
place as the council of the society may direct.
Carful inquiry has convinced the committee
that, in order to carry out these plans, a fund
of at least $2,000 should be secured. It is
requested that subscriptions be sent to the
chairman or to any member of the committee.
Contributions of sums from $1.00 upwards
are asked.
Joseph Priestley was born at Fieldhead in
England in 1733. Although educated for the
ministry, he became noted as a teacher and
lecturer on natural science, and especially as
an investigator in chemistry, devoting his at-
tention largely to the study of gases. Perse-
cuted and shunned as a result of popular
prejudice for his theological views as a dis-
senter from the Established Church, he mi-
grated to America in 1794 and settled with his
family in Northumberland, Pennsylvania.
Here he established a laboratory and con-
tinued his work as an investigator in chem-
istry.
While famous throughout Europe and in
America for his historical and philosophical
writings, for his important work on the His-
tory of Electricity, and many other contribu-
tions to scientific literature, he is more es-
pecially known to modern chemists for his
researches on the chemistry of gases, which
culminated in 1774 in the discovery of oxygen,
described in his treatise entitled “ Experi-
ments and Observations on Different Kinds
of Airs.”
He continued in America to be a contributor
to scientific and theological literature until
his death in Northumberland in 1804.
On July 31, 1874, many of the leading
chemists of America met near the grave of
Joseph Priestley at Northumberland to honor
Avueust 17, 1917]
the memory of the man who had discovered
oxygen one hundred years before. In the
account of the proceedings detailed in the
American Chemist for 1874, we are told that
a movement was there begun which led later
to the establishment of the American Chem-
ical Society.
And as the foundation of the American
Chemical Society has been thus linked with
the name of Joseph Priestley, it would seem
proper that we should seek in some lasting
way to commemorate his work as an inyes-
tigator and philosopher and tireless searcher
after truth.
It is earnestly hoped that the plans now
proposed by the committee for a memorial will
meet with approval and that we shall be able,
by means of an adequate subscription fund,
to render such honor as is due to the memory
of John Priestley.

SCIENTIFIC EVENTS
A STRUCTURE POSSIBLY FAVORABLE FOR OIL
UNDER THE CENTRAL GREAT PLAINS
In consideration of the present great inter-
est in oil prospects in the Great Plains region,
the United States Geological Survey, Depart-
ment of the Interior, has prepared a report
giving all available information regarding the
structure of that region. No oil or gas has
been found in most of this wide area, but it
contains several anticlines and domes like those
which yield oil and gas in central Kansas,
Oklahoma and Colorado, so that the conditions
are encouraging for exploratory borings.
Wells have been drilled at a number of places,
but most of them have either been sunk where
the structure was not favorable to the occur-
rence of oil or gas or have not been drilled deep
enough to test all the strata.
The structure of the Central Great Plains
north of latitude 37° has been investigated by
geologist N. H. Darton, who has prepared a
map showing by contour lines the location and
configuration of a number of promising anti-
clines and domes. One of these domes lies on
the Nebraska-South Dakota line northeast of
Chadron, its crest being on White River. It
may continue southward under the great sand
cover in Nebraska to join an anticline of mod-
erate prominence which crosses the Republican
Valley just above Cambridge, Nebr., and ex-
tends into the western part of Norton county,
Kans.
A local dome of considerable height occurs
in Hamilton county, Kans., its crest being 6
or 8 miles southwest of Syracuse. It is on the
flank of the largest dome in the Central Great
Plains, which arches up the strata in Baca,
Las Animas, and Bent counties, Colo., and ad-
jacent parts of northern New Mexico. Its
crest is under the Mesa del Mayo, on the state
line. A dike of igneous rock not far west of
this place contains petroleum, which undoubt-
edly had its source in some of the uplifted
strata.
A dome east of Fort Collins, into which a
drill has penetrated 3,900 feet, also presents
structure favorable for oil, and when the drill
reaches the beds that yield oil near Boulder it
may find in them a possible reservoir. There
156
are some anticlines and domes in eastern South
Dakota, but the strata above the granite and
quartzite in that area are not thick enough to
offer encouraging prospects.
A prominent anticline in Converse county,
Wyo., with its crest east of Old Woman Creek,
lifts an extensive series of sedimentary rocks
not far southwest of the Black Hills. Another
arch occurs on the west slope of these hills a
few miles northwest of Moorcroft, and on its
sides are oil springs from some underground
source.
MEDICAL STUDENTS AND CONSCRIPTION
THE Journal of the American Medical As-
sociation has obtained information regarding
the draft numbers and numerical order of call
of medical students. There were all told 13,-
764 medical students enrolled during the last
session, of whom 3,379 graduated, leaving 10,-
385, made up of 4,107 freshmen, 3,117 sopho-
mores, 2,866 juniors, and 295 seniors who were
not graduated. Tabulated statistics regard-
ing 5,909 or 56.9 per cent. of all undergraduate
medical students based on direct replies to a
questionnaire are as follows:

While the table represents only a little more
than 56 per cent. of the whole, it gives those
interested an opportunity to estimate the effect
of the draft on the different classes. As
shown in the table, 5,058, or 85.5 per cent. of
the students who have already replied, are sub-
ject to the draft, and of these 29 per cent. are
included in the first call; 19.4 per cent. in the
second call and 51.6 per cent. in later calls;
12.4 per cent. are exempt on account of age,
0.5 per cent. are aliens, and 1.6 per cent. have
already enlisted. As will be noticed, 729 are
SCIENCE
[N. 8. Vou. XLVI. No. 1181
exempt on account of age; of these 606 are
under age, and 123 over the age limit. The
Journal says that unless some arrangement is
made, therefore, whereby these students are
enabled to complete their medical training,
classes in medical schools will be seriously de-
pleted; the supply of physicians for the future
will be seriously reduced, and this country
will suffer from an error similar to that made
in England and France where medical stu-
dents were sent to the front. Furthermore,
failure to exempt medical students from the
draft will be a serious injustice to many, since
a few months ago the Council of National
Defense, with the apparent agreement of the
War Department, urged medical students not
to enlist in the Officers’? Reserve Corps but to
remain in college and complete their medical
training. Had not that request been, made,
many students would have voluntarily enrolled
in officers’ training corps, where many of them
would doubtless have been successful. Even
though less than a third of the medical stu-
dents of draft age will be included in the first
eall, a much larger proportion will be lost to
the medical schools, since, in the absence of a
definite understanding, many of the others
will enlist voluntarily in the ranks, in ambu-
lance corps or in officers’ training corps. A
definite decision on the part of the War De-
partment relative to medical students is im-
perative. Unless such decision is made, not
only will our civil hospitals lack adequate in-
tern service, but the government will lose by
the fact that those capable of skilled service
will have been deflected to work which can be
as well done by others.
PSYCHOPATHOLOGICAL EXAMINATION OF
RECRUITS
Accorp1N¢ to a press bulletin men of the Na-
tional Guards of the various states and of the
new draft army will be subjected to thorough
mental examinations by expert neurologists
and psychopathologists at the concentration
camps before sailing to France, to weed out
the mentally and nervously unfit, whom the
experience of France, Britain and Germany
shows have proved useless and a burden at the
Aveust 17, 1917]
front. Not only are these examinations ex-
pected to weed out those whose nervous sys-
tems are broken down, and the feeble-minded
or imbecile, but they will hinder the draft
evaders from feigning nervousness or mental
sickness. Not only will these expert neurolo-
gists and psychopathologists examine the men
at the cantonments, but they will go to the
front with the men and establish base hos-
pitals adjacent to the orthopedic base hos-
pitals.
Ten of the leading psychopathologists of the
country have been selected for the starting of
this branch of service. They are Dr. E. E.
Southard, director of the psychopathic hospital
of Boston; Dr. Robert M. Yerkes, professor of
comparative psychology at Harvard Univer-
sity; Dr. August Hoch, director of the
psychiatric institute, New York City; Dr.
Adolf Meyer, director of the Phipps Psychiat-
ric Institute, Baltimore; Dr. Albert M. Bar-
rett, director of the State Psychopathic Hos-
pital, Ann Arbor, Mich.; Dr. William A.
White, superintendent of the Government Hos-
pital for the Insane, Washington, D. C.; Dr.
William E. Fernald, superintendent of the
State School for the Feeble Minded at Wa-
verley, Mass.; Dr. Thomas W. Salmon, medical
director of the National Committee for Men-
tal Hygiene of New York City, who has gone
to England for observation; Dr. Joseph P.
Collins, of the New York Neurological Insti-
tute, New York City, and Dr. T. H. Weisen-
burg, president of the American Neurological
Association of Philadelphia.
There are five clinics where leading special-
ists and doctors are preparing for the work.
They have been assigned by the government
for special teaching in neurology and pschi-
atry for commissioned men in the Medical Re-
serve Corps. The courses of six weeks’ dura-
tion, the first course just being completed, are
being given at the following clinics: The Psy-
chopathie Hospital, Boston; Phipps Psychi-
atric Clinic, Baltimore; State Psychopathic
Hospital, Ann Arbor, Mich.; the Neurological
Institute, New York City, and the Psychiatric
Institute, Ward’s Island, New York.

THIRD NATIONAL EXPOSITION OF CHEMICAL
INDUSTRIES
Tue third national exhibition of chemical
industries will be held in the Grand Central
Palace, New York City, during the week of
September 24. Many of the exhibits will have
to do with the uses of chemistry in the making
of war materials, and there will be a special
section devoted to the South which will be
known as the Southern Opportunity Section.
Dr. Charles H. Herty, chairman of the ad-
visory committee of the exposition, will de-
liver the opening address on Monday, Sep-
tember 24, at two o’clock. Professor Julius
Stieglitz, president of the American Chemical
Society; Dr. Colin G. Fink, president of the
American Electro-Chemical Society, and Dr.
G. W. Thompson, president of the American
Institute of Chemical Engineers, will speak
before different sections of the convention.
Other speakers on the program include W. S.
Kies, vice-president of the National City
Bank, who will talk upon “ The Development
of Export Trade with South America”; Pro-
fessor Marston Taylor Bogert, chairman of the
chemistry committee of the National Council,
whose subject will be “The operation and
work of the National Research Council for
the national weal,” and Dr. L. H. Baekeland,
of the Naval Counsulting Board, on “ The
future of the American chemical industry.”
One day will be devoted to a symposium
upon the national resources as opportunities
for chemical industries, and among the
speakers will be: Mr. C. H. Crawford, as-
sistant to president of Nashville, Chattanooga
& St. Louis Ry.; Mr. V. V. Kelsey, chemist-
industrial agent, Carolina, Clinchfield & Ohio
Ry.; Dr. E. A. Schubert, mineralogist-geolo-
gist, Norfork & Western Railway; Dr. T. P.
Maynard, mineralogist-geologist, Central of
Georgia Ry. and Atlantic Coast Line Ry.; Dr.
J. H. Watkins, geologist, Southern Railway.
The motion-picture program will be one of
wide interest. The American Cyanamid Com-
pany and General Electric Company have
already arranged to supply their films. The
Bureau of Commercial Economics at Wash-
ington will supply many toward completing
158
the range of industrial films. At the last ex-
position two floors of the big building were
occupied by 187 exhibitors. This year three
floors, possibly more, will be occupied. Al-
ready the list of exhibitors contains 250 names
of companies entering every field of industry.

DISCUSSION AND CORRESPONDENCE
THE COST OF ROAST PIG
CuarLes Lamp, in his “ Dissertation on
Roast Pig” relates that, according to an
ancient manuscript, the hut of a Chinese
swineherd taking fire, a litter of newly far-
rowed pigs perished in the conflagration.
Seeking to find if life remained in any of
them, the swineherd burned his fingers on the
hot body of a pig. To alleviate the pain he
naturally put his fingers into his mouth and
so discovered the delicious flavor of roast
pig. The taste spread rapidly and shortly
all China was ablaze with burning pig pens
sacrificed for the sake of producing the new
delicacy.
In the food crisis with which the world is
apparently confronted, roast pig may stand
for the supply of animal products in general,
and our methods for producing them hitherto
have not been altogether unlike that for
roasting pigs attributed to the Chinese. At
this juncture, it seems pertinent to inquire
whether our practises in this respect do not
need to be modified so as to contribute more
effectively to the feeding of the nations.
Aveust 17, 1917]
Roast pig, to those who like it, is not only a
delicacy but a valuable article of diet, but
nevertheless, as the Chinese presumably came
to realize, it is possible to pay too high a price
for it, and while a proposal to restrict rather
than to promote meat production in the
present crisis may appear both irrational and
unpatriotic it may nevertheless be in the in-
terest of true food economy.
This is because of one cardinal fact which
the advocates of the multiplication of farm
live stock, the prohibition of the slaughter
of young animals, ete., overlook. That fact
is that not only must the meat or milk pro-
ducing animal be fed (and even this appears
to be forgotten at times) but that the con-
version of feed into animal products is a proc-
ess of relatively low efficiency.
Man needs food primarily as fuel to supply
the energy for his activities and secondarily
to furnish the repair material (protein) for
the bodily machinery. An active adult re-
quires daily some 4,000 calories of energy,
the amount varying more or less according
to the amount of physical work done. He
can get this energy from either vegetable or
animal products. He may make his wheat
or corn into bread and use that bread as body
fuel, or he may feed them to animals and
consume the resulting meat or milk. The
latter are excellent body fuels and are de-
sirable ingredients of the dietary but their
production from grains is a very wasteful
process. It may be roughly estimated that
about 24 per cent. of the energy of grain is
recovered for human consumption in pork,
about 18 per cent. in milk and only about 3.5
per cent.in beef and mutton. In other words,
the farmer who feeds bread grains to his
stock is unconsciously imitating the Chinese
method and is burning up 75 to 97 per cent.
of them in order to produce for us a small
residue of roast pig, and so is diminishing
the total stock of human food.
Now most of us like roast pig and its pro-
duction in this way has doubtless been eco-
nomically justifiable in years past when our
food supply was vastly in excess of our needs.
To-day the case is different. No longer can
SCIENCE
161
we continue to take the children’s bread
and cast it to the brutes. If our meat supply
is to be maintained or increased it must be
in some other way. All the edible products
which the farmer’s acres can yield are needed
for human consumption. The task of the stock
feeder must be to utilize through his skill
and knowledge the inedible products of the
farm and factory such as hay, corn stalks,
straw, bran, brewers’ and distillers’ grains,
gluten feed, and the like, and to make at least
a fraction of them available for man’s use. In
so doing he will be really adding to the food sup-
ply and will be rendering a great public sevice.
Rather than seek to stimulate live stock hus-
bandry the ideal should be to adjust it to the
limits set by the available supply of forage
crops and by-product feeding stuffs while, on
the other hand, utilizing these to the greatest
practicable extent, because in this way we save
some of what would otherwise be a total loss.
In particular the recommendation to raise
more hogs seems to call for some qualification.
It is indeed true, as several have pointed out,
that the hog can make more pounds of edible
meat from a given amount of concentrated
feed than any other class of live stock. The
point is that with the present demand for
bread grains we can not afford the cost of the
conversion. So far as hogs can be raised on
forage and by-products the recommendation
is sound, and this animal can play an impor-
tant part in utilizing domestic and other
wastes, but the hog is the great competitor
of man for the higher grades of food and in
swine husbandry as ordinarily conducted we
are in danger of paying too much for our
roast pig. Cattle and sheep, on the other
hand, although less efficient as converters, can
utilize products which man can not use and
save some of their potential value as human
food. From this point of view, as well as on
account of the importance of milk to infants
and invalids, the high economy of food pro-
duction by the dairy cow deserves careful con-
sideration, although of course the large labor
requirement is a counter-balancing factor.
At any rate, it is clear that at the present
time enthusiastic but ill considered ‘“ boom-
162
ing” of live stock production may do more
harm than good. If it is desirable to restrict
or prohibit the production of alcohol from
grain or potatoes on the ground that it in-
volves a waste of food value, the same reason
calls for restriction of the burning-up of these
materials to produce roast pig. This means,
of course, a limited meat supply. To some
of us this may seem a hardship. Meat, how-
ever, is by no means the essential that we
have been wont to suppose and partial depriv-
ation of it is not inconsistent with high
bodily efficiency. Certainly no patriotic citi-
zen would wish to insist on his customary
allowance of roast pig at the cost of the food
supply of his brothers in the trenches.

A NEW CONTRIBUTION TO AMERICAN
GEOLOGY
Unper the heading “Work going on at
Kilauea Volcano” there was published in Sct-
ENCE of September 12, 1913, an account from
Hawaii by Mr. Geo. Carroll Curtis, of the field
work, cirkut and kite camera surveys being
conducted in the great active crater, In con-
nection with the construction of a natural-
istic model for the geological department of
Harvard University.
After four years of continuous effort this
work has been completed and installed in the
university museum. While the size and time
required distinguish it, the principles it in-
volves of faithful and expressive reproduction
of the earth surface is of special significance,
as it seems to mark a distinct progress in the
complex subject of representing our earth in
true relief and character. A single glance at
the great model is convincing, for in looking
upon this vast collection of accurate data, one
receives the impression that he is viewing the
outdoor field itself! The model looks like the
actual ground because it has been made lke
it, an immense amount of information never
before collected having been incorporated from
the special surveys. This is a signal triumph
in the truthful interpretation of a splendid
type of geological structure such as Kilauea
SCIENCE
[N. S. Vou. XLVI. No. 1181
presents. It clearly indicates the novel and
broad interest which awaits the earth sciences
in the reproduction of their museum natural
history specimens through the medium of
serious work in land relief.
The longest time previously given to any
work we haye had of this nature, was two
years, in the naturalistic reproduction of the
coral island Bora Bora, under the instigation
of Alexander Agassiz. It was made to illus-
trate the typical “high coral island.” This
work, completed in 1907, was the first in the
land where the necessary photographic survey
and special field work were employed to truth-
fully reproduce a land form type, and marked
the introduction of the naturalistic or land-
scape model in American exhibition. The
character of the work was illustrated by the
photographs made from it, bearing a surpris-
ing resemblance to those taken on the actual
ground, a thing previously unlooked for in
our land reliefs. This unique contribution to
the progress of earth science is still considered
the most complete exposition of a coral island
known, and as the pioneer in naturalistic land
relief (the completest expression which science
and art can give of the earth’s surface) will
always remain a most significant piece of
work.
The Kilauea model represents the progress
of the intervening decade, in the new and
developing art of the accurate reproduction of
the surface of the planet, and is the culmina-
tion of the unique experience which has come
through a training in both geology and in art,
which Mr. Curtis has given to this profound
though much misrepresented work of earth re-
lief. Against precedent he has attempted to
make a profession rather than a business of a
work which calls for treatment adequate to
the dignity of natural science. Valuable as
may be the individual models to which Curtis
has given so much time and study, it is in the
establishment of a standard more in keeping
with that called for by the natural sciences
and by the meaning and interest of the face
of our earth, that his most significant achieve-
1 Darwin, ‘Structure and Distribution of Coral
Reefs,’’ p. 4.
Aveust 17, 1917]
ment lies. That this standard is to-day prob-
ably second to none is to be seen in the Kil-
auea model which presents several important
innovations in the development of land relief,
including the application of cirkut panorama
and aerial photography and the ecycloramic
background.
The Kilauea undertaking marks the advent
of the American geologist into the work most
complete and effective of any known for repre-
sentation of the immense forms with which he
deals. Some conception of what this subject,
calling for the best that modern science and
art can offer, has in store, may be had from
statements of those who have visited the active
voleano and maintain that a better compre-
hension of the huge crater may be obtained
from the model in Cambridge than in Hawaii
itself, owing to the vast dimensions of the
Kilauea region. What is yet in store for the
earth sciences through the naturalistic repro-
duction in relief of remaining great types of
land form, should give some measure of the
value of this contribution.

QUOTATIONS
A BRITISH REPORT ON INDUSTRIAL RESEARCH
IN AMERICA
Tue Advisory Council for Scientific and
Industrial Research has issued the first of a
series of papers in which, under the title of
Seience and Industry, it intends publishing
information of value to manufacturers. The
intention was announced in the report of the
Committee of the Privy Council, of which an
account appeared in these columns; and the
present instalment by Mr. A. P. M. Fleming,
of the British Westinghouse Company, on in-
dustrial research in the United States, is so
full of information and practical suggestion
that engineers will learn with regret that there
is little prospect of further instalments ap-
pearing during the war.
The paper differs from much that issues
from the Stationery Office in being essentially
a practical work, not loaded with statistics and
theoretical considerations. It is a plain state-
ment of facts and practical suggestions very
important to industry, set out for British
manufacturers by one of their own body in
such a way that what it describes and what it
suggests can readily be understood; it is illus-
trated by 85 half-page or full-page blocks, and *
published—at the public cost—at the price of
1s. No appreciable expense either of time or
brain-stuff or money stands between the mes-
sage of the volume and the public for whom
it is meant; and while there is no point in
summarizing what can be easily acquired and
digested, some of its facts and the conse-
quences that they suggest are worth consider-
ation.
The modern tendeney of American manu-
facture to research may perhaps be seen most
strikingly in what is being done by manufac-
turing and similar corporations themselves.
Examples are to be found alike in the mechan-
ical, electrical, and chemical industries, aad
are on every variety of scale, up to the £30,000
per year to which the Eastman Kodak Com-
164
pany devotes something under 1 per cent. of
its profits, and the £80,000 to £100,000 a year
spent by the General Electric Company of
Schenectady. Mr. Fleming gives particulars
of what is being done by each of some twenty
corporations, but the list could easily be made
very much longer. Most of these laboratories
have sprung up in quite recent years; and
their number is constantly increasing. The
increase is not merely in number. It is as
remarkable in its growing breadth. The lab-
oratories of these firms undertake not merely
the routine of testing of materials and prod-
ucts and the more or less empirical adventures
after new products that was formerly the bus-
iness of a works’ laboratory. At the one end
of the scale they carry out experiments on the
discovery of new products and the elaboration
of new designs into the full manufacturing
scale, and the laboratory supplies the needs
of the market as if it were itself a works, until
they outgrow the capacity of its plant and call
for a new works of their own. At the other
end of the scale they undertake inquiries into
questions of pure science, of the solution of
which no one can see any industrial applica-
tion. They keep men investigating such prob-
lems constantly and perseveringly, and give
them admirably equipped laboratories for the
purpose. This sort of thing is being done in
works after works, and every year adds to their
number and the elaboration of their equip-
ment. All the time, in spite of the enormous
sums that are being spent on what at first
sight is not only unproductive work, but work
which tends to subordinate the wholesome rule
of practise to the fantastic and costly demands
of laboratories, the thing pays. The fact that
the habit has grown so far is good prima-facie
evidence that it must pay, for American bus-
iness houses do not fling good money after
bad. But there is no need to depend on in-
ference or prima-facie evidence. The indi-
vidual experience of those who have tried it
shows that in fact it has paid, and the air in
America is thick with plans to extend the prac-
tise of applying science to help industry; for
great as is the extent of what has been done
already, it is only a tiny fraction of what in
SCIENCE
[N. S. Vou. XLVI. No. 1181
American industry there is still room and the
intention to do.
Side by side with these corporations and
firms three groups of institutions are work-
ing to the same ends. Mr. Fleming quotes a
dozen or more separate industries with their
trade associations, each of which is under-
taking research for the common benefit of their
members; sometimes in their own common
research laboratories, sometimes in those of
their members, sometimes through university
or the Bureau of Standards staffs. An ex-
cellent instance of an important trade of
which all members, great as well as small,
have gained greatly by research work com-
municated to all alike, is that of the canners.
The Canners’ Association spends some £6,000
or £7,000 a year on its central laboratory,
besides a good deal more on work done in the
factories of individual members; and it is
considered that the largest members have as
much interest as the small in the results being
made common to all, because the risk of the
whole trade being discredited by imperfect
production is thus minimized. Over a dozen
universities and colleges, again, are now
‘running laboratories devoted not only to
investigations in pure science which may ulti-
mately find a practical application, but to
industrial researches for which the application
is waiting as soon as the solution of the prob-
lems is found. In many instances such work
is done not on the strength of foundations,
but at the request and expense and for the
benefit of commercial firms and other indus-
trial bodies, such as railway companies.—Lon-

SCIENTIFIC BOOKS
Use of Mean Sea Level as the Datum for Ele-
vations. (Special Publication No. 41.) By
E. Lester Jones, Superintendent, U. S.
Coast and Geodetic Survey, Washington,
Government Printing Office. 1917.
This pamphlet presents a very strong case
in favor of the adoption of a single datum for
the elevations of the country in order to elimi-
nate the confusion which results from the em-
ployment of arbitrary planes of reference.
Aveust 17, 1917]
There is scarcely any surveying or civil
engineering which does not require that dif-
ferences in elevation be determined by spirit
leveling and in nearly all cases the absolute
elevation of the bench marks above some plane
of reference or datum is determined. Effi-
ciency in operation frequently depends upon
the datum selected. There are many other
branches of science besides that of engineering
in which absolute elevations are needed.
The selection of a fundamental datum is a
matter of great importance. Only slight con-
sideration leads one to conclude that the ideal
datum for a nation is one which may be estab-
lished at many places. The only one of this
kind is mean sea level.
Mean sea level may be established within a
very small fraction of a foot by continuous
tidal observations for at least a year. It has
been found from precise leveling observations
that mean sea level, as established at different
points on the open coasts, is at all such points
in the same equipotential surface; that is, if
there were no resistance of the water and wind
to the movement of an object floating on the
ocean, the object could be moved from one
point on the coast to another without perform-
ing any work—there would be no lifting neces-
sary. While this statement may not be abso-
lutely true, yet it is so nearly the case that for
all engineering and surveying purposes it may
be accepted as rigidly true.
Mean sea level is used exclusively in the
work of the Coast and Geodetic Survey and
the U. S. Geological Survey. It is used to a
certain extent by many other engineering
bureaus of the government.
In December, 1916, the Coast and Geodetic
Survey sent the following letter, or one similar
to it, to the chief engineers of most of the
large cities of the country, to the State Engi-
neer of each state, and to the chief engineer of
each of about 150 railroads in the United
States:
As you know, one of the important questions of
the United States Coast and Geodetie Survey is
the extension over the country of a network of
precise leveling which will give elevations of great
accuracy, based upon mean sea level.
SCIENCE
165
We believe that this precise leveling is essential
in the surveying and engineering work done in this
country by various public and private agencies.
The network will enable engineers to use the sea-
level datum on new projects and to reduce to this
datum existing elevations referred to arbitrary
datums. We believe that this country should
eventually have but one datum, in order that all
engineering and surveying work may be easily
coordinated. We believe also, that the presence
of various datums leads to much confusion and
waste.
In order that we may get into closer touch with
the needs of the engineering profession, I should
be glad if you will let me know to what extent
your state is basing the elevations of its road and
other surveys and engineering works upon mean
sea level; also whether the use of various arbitrary
datums by counties, cities and private organiza-
tions within your state is a serious matter in the
industrial development of your state.
Replies were received from many of the
engineers to whom the above letter was written.
The opinions expressed were almost unani-
mously in favor of the adoption of mean sea
level as the datum for elevations.
The pamphlet under discussion contains
quotations from many of the letters received
by the Survey. One of the quotations, typical
of most of them, reads:
So far as our experience has taught us there can
be no question as to the desirability of a universal
datum plane, and I think there can be no doubt in
the minds of engineers engaged in municipal work
that mean sea level is the only logical datum to
adopt.
In your advocacy of an extension of such bench
marks you deserve the support and cooperation of
every engineer in the country.
Another reads:
We agree with you that it would be very valu-
able to the state if a system of levels could be es-
tablished, and believe that such will need to be
done in the near future in order to correlate the
drainage, highway and other engineering work in
the state.
It is realized by the members of the Coast
and Geodetic Survey that much of the con-
fusion in datums which now exist, is due to
the fact that the precise level net of the United
States was not extended in the past as rapidly
166
as it should have been. It, of course, was im-
possible, or rather impracticable, to extend a
precise level net into areas through which rail-
roads had not been run, for the expense would
have been prohibitive. It may be that the Sur-
vey did not fully realize the necessity for hav-
ing all engineering and surveying work on the
same datum, but in recent years it has become
fully alive to the necessity of having a single
datum for the entire country, and it is conse-
quently extending its precise leveling net as
rapidly as funds available will permit.
While it is of value to the nation for various
organizations and individuals to adopt and use
mean sea-level datum for their elevations, the
country will benefit still more if each organi-
zation doing extensive leveling will publish in
pamphlet form the elevations and descriptions
of the bench marks they may establish in order
that other organizations and individuals may
properly coordinate their levels. Engineers
are urged also to use substantial bench marks
in order that future work may be benefited by
their preservation.
The amount of precise leveling which should
be done by the federal government can not be
foretold. It must depend upon the needs of
the various organizations and individuals
using the results. After a certain development
of the precise level net which appears now to
be absolutely necessary, the rapidity with
which further extensions are made should de-
pend upon the development of the country.
But such further extensions should precede
rather than follow such development, as is
proved by the unfortunate condition of affairs
in much of our engineering and surveying
work, due to lack of precise elevations in the
past, when such work was inaugurated.
This paper on mean sea level should, and no
doubt will, do much good in furthering the
universal adoption of mean sea level as the
reference surface for all elevations.
The publication of such pamphlets by goy-
ernment organizations is to be commended,
for they present facts to the public in an ef-
fective way which may otherwise be buried
for years in valuable but more cumbersome
government reports with which all of us are
more or less familiar. WituiAM Bowie

INTRA-VITAM COLOR REACTIONS
We have slowly come to have great confi-
dence in the specificity of certain physiological
actions. We introduce into an organism cer-
tain substances, and definite results follow; but
about the only thing we know in the matter is
that the results follow with certainty. In such
cases, if only we could see what it is that hap-
pens while it is happening, it seems certain
that important advances would be made in our
knowledge of nutrition, growth and decay—
of physiology, pathology and medicine.
If substances giving color reactions in liv-
ing tissues could be applied to small, trans-
parent, varied and highly complex living or-
SCIENCE
167
ganisms, under circumstances that would per-
mit microscopic examination while the reac-
tions are in progress, we might hope for more
light on this exceedingly important subject.
Experiments I have made lead to the belief
that many of the conditions requisite for suc-
cess in this line of investigation can be much
more fully realized than hitherto by feeding
colored substances, notably coal-tar dyes, to
free-living nematodes.
These minute, transparent animals are com-
paratively highly organized; not only this, but
also extremely varied in their mode of life.
Some are exclusively vegetarian, others ex-
clusively carnivorous, and others omnivorous.
They constitute a group composed probably of
hundreds of thousands of species, embodying
an almost inconceivable number of kinds of
physiological action. Their organs are en-
closed in a thin transparent cuticle, and are
strung out so as to make them unusually suit-
able for intra-vitam examination. Under
slight pressure the nema flattens out more or
less without losing its vitality sufficiently to
preclude satisfactory intra-vitam examination
under the highest powers of the microscope.
Observing certain precautions, I find that a
great variety of coal-tar compounds and other
colored compounds can be fed to nemas, ap-
parently without interfering materially with
their normal metabolism. I have had the best
results by cumulative action, using small quan-
tities of color dissolved in the medium in
which the nema lived, and allowing the dye to
act for days or weeks.
Not infrequently the dyes prove to be highly
specific in their action. Only certain cells, or
only definite parts of certain cells, exhibit vis-
ible reactions in the form of colorations. The
results obtained by the use of any given dye
may be quite varied. It is evident in many
eases that the dye is digested and assimilated,
thereby undergoing molecular changes by
which it is converted into new compounds in a
manner analogous to the processes exemplified
in chemical laboratories devoted to the produc-
tion of aniline dyes. Thus, a dye may give
rise to several different colors, none of them
like that of the dye itself, and all of them very
168
likely due to new compounds. Often I have
seen considerable evidence pointing to the con-
clusion that in some cases the dyes fed are
converted into colorless compounds during the
process of digestion (a reduction phenome-
non), and these colorless compounds recon-
verted into colored substances after they arrive
at certain destinations or conditions. The
number of changes these “ living laboratories ”
can ring on the molecular structure of a given
dye must in some cases be very considerable.
Two or more dyes fed simultaneously some-
times produce results more or less independent
of each other. The spectacles are very bril-
liant.
Using these methods I have been able to
demonstrate within the confines of a single cell
the existence of an unsuspected number of
kinds of “granules,” manifestly playing dif-
ferent roles. After the differences among these
bodies have been shown in this way, it is some-
times possible to perceive corresponding morph-
ological differences; but without the aid of the
color reactions the differences would never
have been suspected.
The main thing to bear in mind is that on the
basis of our present more complete knowledge
of the chemical and physical properties of coal-
tar-derivatives these color reactions in living
nemas may be made the index of physiological
characters possessed by cells and their com-
ponents. In view of the great variety of the
known coal-tar derivatives, and the great va-
riety of physiological activities exemplified in
the free-living nemas, it seems to me a very
reasonable hope that researches directed along
this line will lead to important results, and
that the nemas may become classical objects in
cell and general physiology, as they have al-
ready become in sex physiology.
A new and rather extensive nomenclature
will become necessary. It will be needful to
distinguish between the results of intra-vitam,
intra-mortem and post-mortem staining; for
these three terms represent as many different
phases in the chemical reactions that take
place during the course of the experiments.
As the cells lose vitality, new color reactions
occur, and the death of the cell is followed by
SCIENCE
[N. S. Vou. XLVI. No. 1181
further equally marked changes in the reac-
tions.
The cell elements I have mentioned vary in
size, but most of them are exceedingly small,
many so small that they are on the limits of
visibility, using the very best instruments with
the greatest skill and under the most favorable
conditions. On the other hand, some of them
are large enough so that they can be examined
in considerable detail and their structures
made out. Among them are the bodies cur-
rently referred to under the name mitochon-
dria and other more or less synonymous words.
As it will be some time before we can estab-
lish a rational nomenclature for these nu-
merous intracellular structures, it is desirable
meanwhile to adopt terms that will permit in-
telligent discussion of our discoveries as they
are made. While the principles underlying
such a nomenclature are easily defined, it is by
no means easy, in the present condition of
things, to suggest suitable short and expres-
sive roots to be used as a basis. There will be
less liability of confusion if the names first
employed relate to form, size and position
rather than to function.
Investigations of this character are not un-
likely to stimulate further research in connec-
tion with aniline derivatives. Present efforts
are directed toward the discovery of dyes of
greater or less permanency. Permanency,
however, is of little moment in these investi-
gations; what is of moment is the chemical
composition and physical properties of the
dyes. No doubt dyes of a greater range of
composition can be produced if permanency be
disregarded. Furthermore, as already hinted,
colorless compounds may be used in intra-
vitam work if in the course of the metabolism
they are converted into colored compounds.
The results of recent studies of dies as chem-
ical indicators come into play, and give valu-
able evidence in determining acidity and alka-
linity.
I am almost ready to express the opinion
that a small army of investigators should be
engaged on the problems opened up in this
way. The equipment needed by the investi-
gator is as follows: He must be a very good
Aueust 17, 1917]
microscopist, versed in physiology, cytology
and histology. He should be conversant with
the chemistry of the coal-tar compounds, not so
much from the viewpoint of the maker of dyes
. as from that of the broad-minded chemist,
freed from the econorhic domination of the
dye industry, for, as before remarked, fugi-
tive dyes, and even colorless compounds, are
possible factors in such investigations as are
here under discussion. He should have a
working knowledge of nemas.
ILLUMINATION
In order to distinguish with accuracy among
intra-vitam color reactions it is necessary to
be very particular about illumination. The
most perfectly corrected lenses must be used,
both as condenser and objective; and the light
used must be as nearly white as possible. The
best source of light known to me for these re-
searches is bright sunlight reflected from a
plane matte white reflector. The reflector
should be several feet across, and placed at a
distance from the microscope several times its
own diameter. It should be universally ad-
justable, so that it can be set to reflect a maxi-
mum of light to the mirror of the microscope
—all the better if heliostatic. A good surface
for the screen is made by whitewashing a
rather finely woven cotton cloth.

The best optical arrangement I have tried is
the use of one apochromatic objective as a con-
denser for another apochromatic objective. I
have been using with success a 2 mm. apochro-

matic as a condenser for a 2 mm. or 1.5 mm.
apochromatic objective. These precautions are
necessary if fine color distinctions are to be
made with the greatest possible accuracy. If
these precautions are taken it will be found
that fine distinctions can be made with such
precision as to dispel all doubt as to the exist-
ence, side by side, in the same cell of definite
structures of varying character that it would
otherwise be impossible or exceedingly diffi-
cult to distinguish from each other.

The use of an ordinary apochromatic objec-
tive as a condenser necessitates the use of a
special object slide, consisting essentially of a
carrier and two cover glasses. The object is
mounted between the cover glasses. Such a
slide is shown in the accompanying illustra-
tion. The substage of the microscope should
have a centering arrangement and a rack and
pinion or screw focusing adjustment. A little
experience with an apparatus of this sort, in
which all known precautions are taken to re-
move color from the optical system, leads one
to distrust the ordinary Abbé substage conden-
ser where fine distinctions are to be made be-
tween colors, especially if the colors are of
similar character. N. A. Coss

The positive and negative specific heat of satu-
rated vapors: F. P. Sreset. A vapor expanding
from a temperature 7 to the temperature T—1
reversibly, yields the maximal work W due to the
latent heat of vaporization H introduced at the
higher temperature in accordance with the second
law expressible in equivalent calories as
T— (T—1)
W =. — L#!
T r calories.
This amount of work is in many cases greater than
170
the difference in the total heat of the vapor L be-
tween the temperatures 7 and T—1 degrees abso-
lute, viz., L—Z, and in this case an amount of
heat equal to H/T =(L—L,) must be added to
maintain the vapor in a saturated condition, and it
is therefore called the ‘‘negative specific heat’’ at
the temperature T. If L —L is greater than H/T
the difference of heat must be added and it is then
called ‘‘positive specific heat.’? The examples
show that all the numerical values in this respect
determined by Clausius on a somewhat different
basis agree perfectly with those obtained after the
above formula, which agreement, however, is not
found with other results obtained by other authors
on a similar basis, apparently due to errors of
judgment so liable in the application of the cal-
eulus. Moreover, it is argued that instead of the
heat quantity H/T which represents the net work
when the expansion takes place in a reversible
eycle, the heat quantity We representing the maxi-
max work in reversible expansion should be used,
which changes the values of positive and negative
heat slightly.
The separation of erbium from yttrium: B. 8.
Hoprins and Epwarp WicHErs. The erbium-
yttrium material used in the investigation was ob-
tained by fractional crystallization of the bro-
mates. Methods recommended by Drossbach and
Wirth could not be duplicated with the success ob-
tained by these workers. Cobalticymide precipita-
tion as recommended by James, was found to give
a good separation, but offered practical difficulties.
Precipitation with sodium nitrite as used by Hop-
kins and Balke found to give a rapid separation
when used with material which was predominantly
yttrium.
A study of the ratio of Er,03:2 ErCl,: C. W.
BALKE and Epwarp WicHeErs. A brief discussion
of other ratios used in determining the atomic
weights of the rare earth elements was given and
the constaney of composition of the rare earth
sulphates questioned. The method of applying the
oxide-chloride ratio to erbium was described and
data given which give an atomic weight approxi-
mately one unit higher than the present value.
A thermal study of some members of the system
PbO — SiO,: L. I. SHaw and B. H. Batt. Many
mixtures of PbO and SiO, varying in composition
from 40 per cent. to 90 per cent. PbO were melted
jn an electric furnace and the records of their
thermal conduct plotted on time-temperature dia-
grams. (In some cases PbO, was used instead of
PbO and its behavior is noted.) The significant
temperatures of these graphs were then combined

[N. S. Vou. XLVI. No, 1181
into a composite temperature and it was concluded
that the system is a case of solids in solid solution.
Two maxima corresponding to the composition
PbO — SiO, and 2 PhO—SiO, were found and
another 2 PBO—-5 SiO, was clearly indicated.
Two eutecties are indicated, though the lower one
may be a transition point of the one of the higher
melting point. As noted by previous investiga-
tors, a transition point of SiO, was found at 540°-
580° C. All mixes sintered at 690° + 10° C.
A study of the change of conductivity with time
in the system methyl alcohol-iodine-water: L. I.
SHaw and Joun P. Trickery. Conductivities of
solutions of iodine in methyl alcohol of various
boiling points have been measured. It was found
that the conductivity increased much more rapidly
in the case of the solutions in alcohol of higher
boiling points; also, that the conductivity reached
a higher value in the case of the solutions from the
higher boiling point alcohols. It was suggested
that this was probably due to the water content of
the alcohol. It was found that a smooth curve
could be drawn through the points at which the
conductivity of the various solutions became con-
stant. Suggestions as to the probable reaction
were given.
The solubility of pure radium sulfate: S. C.
Linp, C. F. WuHiITTEMoRE and J. HE. UNDERWOOD.
The solubility of RaSO, in water and other solu-
tions is of practical interest since all processes for
the recovery of radium from its ores involve, at
some stage, the precipitation of radium together
with barium as sulfate.
Studies in pseudo-isotopy—Part I: 8. C. Linn.
Experiments of the author and others have shown
that when radium and barium are partially precipi-
tated from a solution containing a mixture of the
two, no change in relative concentration takes
place. This is true for sulfate, oxolate, carbonate,
and perhaps all other difficulty soluble salts, and
bears an exact analogy to the inseparability of the
isotopic elements. The fact that radium and
barium are only. pseudo-isotopic, however, is shown
from the great divergence of their atomic num-
bers, and their ready separation by recrystalliza-
tion of the chlorides or bromides. It has been
shown in the preceding paper that the assumption
of identical solubility of RaSO, and BaSO, in
analogy to their pseudo-isotopie action in precipi-
tation reactions, is far from the truth. Conversely,
this must raise the question, from the purely ex-
perimental side, as to the truth of the assumption
generally made of identical solubility of true iso-
topes.

THE IMPORTANCE OF MOLD ACTION
IN SOILS1
Tue development of soil bacteriology
during the last decade has been truly re-
markable. Many fundamental problems
connected with the occurrence and activi-
ties of bacteria in soils have been attacked
and considerable progress has been made
toward their solution. While much work
still remains to be done along this line, re-
sults already secured show, in a rather defi-
nite way, the importance of bacterial ac-
tion in soils from the fertility standpoint.
According to recent investigations, how-
ever, bacteria are not the only microorgan-
isms which exert an influence on soil fer-
tility. Molds, protozoa and algz have been
found quite commonly, and evidently their
action, especially that of molds, must also
be considered in determining the crop-pro-
ducing power of soils. The subject of
microorganic life in the soil has, therefore,
been considerably broadened and compli-
cated.
The oceurrence of molds in soils has been
noted many times in the past in connection
with bacteriological and other studies and
various investigations have dealt in a more
or less general way with the action of these
organisms. It is only within the last year,
however, that an attempt has been made in
a logical and comprehensive manner to
study the occurrence, distribution and ac-
tivities of molds in soils, and to solve some
of the fundamental problems which arise in
connection with the growth of these organ-
isms. The results secured at the New Jer-
1 Paper presented at the meeting of the Society
of American Bacteriologists, at New Haven, Conn.,

not only furnish a basis upon which future
experiments may rest, but they also indicate
quite distinctly that the growth of molds
in the soil may be of great significance.
The transformation of organic and inor-
ganic compounds in the soil has long been
considered the particular function of soil
bacteria, but molds may also play an im-
portant réle in such processes, and indeed
it is conceivable that in some instances they
may prove largely responsible for the
simplification of complex soil materials.
It is not the purpose of this paper to re-
view the previous studies on molds, for ex-
cellent bibliographies have been presented
in the work of Waksman‘ and Coleman? al-
ready referred to. It is desired merely to
eall attention in a brief way to the varied
action of molds in soils, and to present a
compilation of various published data and
some of our own unpublished results along
this line, with the idea of emphasizing the
need of further study of these organisms.
In the first place, the number of molds
in soils should be considered, and while data
along this line are far from conclusive, it
has been shown that large numbers of these
organisms are always present. Especially is
this true for soils rich in humus, and acid in
reaction. But the occurrence of fungi is
not restricted to such abnormal soils. Neu-
tral, well-aerated and well-fertilized soils
are also found to contain rich mold floras.
Furthermore, fungi are not limited merely
to the surface soil, but occur in the deeper

soil layers. The well-known predilection of
certain fungi for acid conditions has been
confirmed and leads to interesting conclu-
sions regarding the special importance of
these forms in acid soils in which beneficial
bacterial action is largely restricted.
A very important point in connection
with the occurrence of molds in soils has
been studied recently by Waksman.® While
the counting methods employed have shown
the large numbers of molds in soils, consid-
erable doubt existed as to whether these
counts represented the actual number of
active fungi or only the spores. If spores
alone are present, the activity of molds in
soils may be of less immediate importance
although their presence would indicate pre-
vious active growth as well as future activ-
ity when the soil conditions become satis-
factory for the development of active
forms from the spores. Active mold
growth on the other hand would undoubt-
edly be of immediate importance in the
chemical changes occurring in the soil.
The value of definite information along this
line is apparent. The careful experiments
of Waksman show that many molds occur
in soils in an active state as well as in the
form of spores. While certain groups do
not appear to be present in an active con-
dition in the soils tested, although the plate
method showed their occurrence as spores,
studies of other soils may lead to different
conclusions.
Conn? has attempted to check Waksman’s
results by the use of smaller quantities of
soil, but was unsuccessful. Using 10 mg.
of soil, he secured no growth of mold my-
celia such as Waksman obtained with
lumps of soil 1 em. in diameter. He de-
seribes a direct microscopic examination of
soils and finds no mold mycelia present.
He concludes from these experiments that
there is serious doubt whether molds exist
in soils in an active form in sufficient num-
Aveust 24, 1917]
bers to be important compared with bac-
teria. There seem to be two questions in-
volved here: How large a proportion of the
number of molds developing on plates rep-
resent active forms and how many spores?
What is the number of active mold forms
which need be present in the soil for them
to be considered important in the various
soil chemical processes ?
The first of these questions is rather diffi-
cult to answer at the present time, but our
experiments indicate that rather a large
proportion of the total number of molds
present in various soils oceur in the active
state. We have found active mold growth
occurring in all the soils thus far examined,
and we have used both Waksman’s and
Conn’s methods. Our results confirm
Waksman’s observations, therefore, and
Conn’s eriticism seems unwarranted, for
active mold mycelia have developed in all
our tests, using not only 10 mgs. but also
smaller quantities of soils, as well as the
larger lumps employed by Waksman. The
soils tested are normal soils, many of them
untreated and none extremely rich in
humus.
Further work along this line is certainly
desirable, but from our observations thus
far there seems no doubt but that fungi
occur actively in soils, and hence we feel
that their action must be important regard-
less of their relative numbers compared
with bacteria. Furthermore the presence
of spores is likewise important for they
may become active in the near future and
bring about their characteristic reac-
tions. The answer to the second ques-
tion mentioned above can only come
after long-continued experiments, but from
the vigorous action of molds noted in so
many cases, as will be pointed out later, it is
evident that the problem of microorganic
activity in relation to soil fertility can not
be completely solved without a knowledge
SCIENCE
173
of mold growth. Perhaps they are not as
important as bacteria, there is no means yet
of knowing, but even if of secondary signifi-
cance they deserve recognition. Our pres-
ent knowledge of soil fertility is too incom-
plete to permit us to pass over hastily any
possibly important factors without thor-
ough study.
We believe, therefore, that molds occur
‘in most soils, both in the active and in the
spore state, and hence they must pass
through their various life cycles in the soil.
Furthermore, different soils undoubtedly
have different fungus floras. Species pres-
ent under one combination of conditions
may be absent under others. Organisms
present only as spores in one case may occur
actively in other instances. Finally, it
seems perfectly possible that the relative
occurrence of active and spore forms of va-
rious organisms may vary in the same soil
with varying conditions of moisture, tem-
perature, aeration, reaction and food
supply.
Considering the occurrence of molds in
an active state in all soils an established
fact, the importance of these organisms in
the decomposition of the soil organic mat-
ter becomes evident. Many experiments
have been conducted along this line and it
has been very clearly demonstrated that
molds are very efficient ammonifiers. Indi-
cations have been secured that there exists
a correlation between the biological stage
of the organisms and the periods of am-
monia accumulation. The largest amount
seems to accompany the periods of spore
germination and the smallest amount the
time preparatory to actual spore formation.
. All the nitrogenous organic materials
which make up the humus content of soils
are easily attacked by various fungus forms
and ammonia is liberated in large amounts.
Part of this ammonia may, of course, be
utilized by them, but by far the larger part
174
is set free and may be subsequently nitrified
for use by the higher plants. Various fertil-
izing materials containing complex nitrog-
enous compounds may be ammonified by
soil fungi, and their decomposition consid-
erably facilitated. For instance, experi-
ments with cyanamide show its rapid trans-
formation to ammonia by certain molds.
Ammonia production from urea by molds
has also been definitely proven.
The non-nitrogenous portion of the soil
organic matter is also attacked by many
molds. Thus experiments have shown that
cellulose is rapidly decomposed by many
species, and other substances such as sugars,
pectins, oils, fats, waxes, organic acids, etc.,
are likewise broken down by molds. Some
recent results secured in our laboratories
show the large carbon-dioxide production
by molds. No doubt, therefore, remains but
that these organisms play an extremely im-
portant part in the decomposition of all soil
organic matter and indeed certain results
indicate that their action along this line
may be much greater than that of bacteria,
at least under certain soil conditions.
No experiments have yet been reported
which indicate that molds may bring about
nitrification, and this process, therefore,
still appears to be purely bacteriological.
Further experiments may modify this con-
clusion.
Denitrification and deazotofication, how-
ever, processes now known to be of slight
significance in normal soils, but which may
oceur in highly manured, specially treated
greenhouse and market garden soils, may
possibly be brought about by the action of
molds. The introduction of these organ-
isms with the manure used may be an im-
portant factor here. Definite data along
this line are lacking at the present time.
Non-symbiotie nitrogen fixation, or azofi-
cation by molds has been studied from time
to time and indications have been secured
SCIENCE .
[N. S. Vou. XLVI. No. 1182
that certain species may be able to utilize
the nitrogen of the atmosphere. The re-
sults, as a whole, however, are far from sat-
isfactory and indeed the conclusion has
been drawn that at the present time the
‘‘weight of the conclusions on the fixation
of nitrogen by fungi seems to be on the
negative side.’”’ Further experiments
along this line are certainly desirable.
The utilization of various nitrogen com-
pounds by molds has been studied to some
extent, and it has been found that ammonia
and nitrate compounds are assimilated by
these organisms in considerable amounts.
Thus under extreme conditions of mold
growth it is conceivable that molds may be
actual competitors with the higher plants
for nitrogenous food materials. It is not be-
lieved, however, that such conditions would
occur except very rarely. A knowledge of
mold growth in soils may be of some signifi-
cance, nevertheless, in connection with the
questions involved in the fertilization of
soils with nitrates and ammonium salts.
The decomposition of mineral compounds
in soils by molds has been studied only to
a very slight extent. Data secured in our
laboratories very largely in connection with
certain chemical and bacteriological stud-
ies indicate, however, that these organisms
may play an extremely important role, not
only in preparing nitrogenous food mate-
rials for plants as has been indicated, but
also in making other mineral constituents
available. Complete data along the various
lines indicated will be published later.
Studies of the production of available
phosphorus by bacteria and molds have
shown the vigorous action of various fungi
in this direction. Several experiments car-
ried out by various methods have shown
that rock phosphate is apparently trans-
formed much more rapidly into a soluble
form by many molds than by bacteria. The
importance of further study along this line
Avcust 24, 1917]
in connection with the solution of the moot
question regarding the relative merits of
rock phosphate and acid phosphate can
readily be seen.
The oxidation of sulfur in the soil, or
sulfofication, a process which has recently
received some attention and which gives
evidence of being of great importance from
the soil fertility standpoint has been shown
to be accomplished by several species of
molds. The action of these organisms in
this process may become of special impor-
tance in connection with the recent sugges-
tion for the production of available phos-
phorus by composting rock phosphate, sul-
fur and soil or manure.
The process of ferrification, or iron oxi-
dation in soils, while largely chemical in
nature according to results thus far se-
cured, is brought about partly by microor-
ganisms and certain molds are apparently
much more active in this action than any
of the bacteria studied.
Experiments on the production of avail-
able potassium by molds should also yield
interesting results. No data have yet been
secured on this point.
In fact, it seems evident that mold action
in soils may be of far greater significance
than has previously been supposed in pre-
paring available food for plant growth. No
longer should the study of microorganic ac-
tivities in soils consider bacteria alone.
Mold action must also be investigated, and
in most cases it is undoubtedly true that
only vague, incomplete results can be se-
cured if such mold studies are not included.
Many results secured in bacteriological in-
vestigations might be explained and inter-
preted much more clearly and definitely if
the activities of molds were considered.
If soil bacteriology is to be developed to
the proper extent in the future and the re-
lation of microorganisms to soil fertility is
to be established with any degree of cer-
SCIENCE
175
tainty, investigations must include not only
bacterial action, but the activities of molds
and possibly also the growth of protozoa —
and alow.
It is certainly desirable that the investi-
gations of molds in soils and their activities
and importance be carried out much more
generally and on a larger scale than is the
ease at present. Here is a field of study
rich in possibilities and the importance of
work along these lines can not be ques-
tioned, P. E. Brown
Iowa AGRICULTURAL EXPERIMENT STATION
THE U. S. BIOLOGICAL STATION AT
BEAUFORT, N. C., DURING 1916
THE general appearance of the site of the
station was materially enhanced during the
year by enlarging the improved portion of the
grounds, and by planting grass, sea oats, trees,
and shrubbery. Through these improvements
the comfortableness of the station was also
increased. The laboratory, as usual, was open
during the summer to special investigators.
The investigators, with a single exception, had
engaged in research at this station before and
they continued during the past season lines
of work previously undertaken.
The present large series of experiments in
diamond-black terrapin culture, which was
started in 1909, has progressed with marked
success. Several new experiments in addition
to those already under way were undertaken.
There are now approximately 1,600 terrapins,
exclusive of the young of 1916, in the pounds
which are being used for experimental pur-
poses. This experimental work has shown
quite conclusively that terrapins can be grown
and kept in vigorous condition in captivity,
for some of the earliest broods, hatched in the
pounds at the station, have reached maturity
and are very prolific in the production of eggs,
and the offspring is equally as vigorous as
that of the wild terrapins confined after ma-
turity had been attained.
A total of 2,611 terrapins hatched during
the summer of 1916 has to date been taken
from the egg beds. This number will be some-
176
what increased in the spring when terrapins
appear that were overlooked in the fall.
' Among these young removed from the egg
beds there are 666 which are offspring of ter-
rapins reared in captivity. The total number
of young produced during the previous year,
including those found in the spring, was 2,128;
of these 50 were offspring of terrapins grown
in captivity. It has been known for some
time that a female terrapin may lay twice
during a single season, but during the past
season through the discovery of 12 nests, ave-
raging 8 eggs to a nest, in a pen where only
four females are confined, it is evident that a
female may lay as often as three times during
a single season.
The most gratifying results of the past year
are the unusually rapid growth of the young
of one year and less of age and the very low
mortality. The death rate among the 1915
brood during the first year was about 8 per
cent., while formerly it occasionally ran as
high as 40 per cent. The death rate among
the young after the age of one year or more
is attained is negligible.
The observations on the habits of fishes was
continued by the director of the station. It
is very noteworthy that food fishes generally
were unusually scarce in the Beaufort region
during the past year. The “gray trout”
(Cynoscion regalis) which is normally, with
perhaps a single exception, the most important
food fish of the locality, was so scarce that the
fishery was almost wholly abandoned. The
almost total failure of a “run” of the two
important fall species, the spot (Lezostomus
zanthurus) and the jumping mullet (Mugil
cephalus), is equally as noteworthy.
The pig fish (Orthopristis chrysopterus)
was found in spawning condition on the inner
shore of Shackelford Banks during May and
the early part of June, but the eggs of this
species seem to be difficult to hatch artificially.
Spawn taken in the field by stripping was
brought to the laboratory for hatching, but
these efforts failed. Then ripe or nearly ripe
fish were confined in live cars and tanks.
Those in the live ears were stripped when ap-
parently very ripe, and those in the tanks were
SCIENCE
[N. S. Vou. XLVI. No. 1182
allowed to spawn naturally. At no time was
fertilization obtained in eggs artificially
spawned, but of those spawned naturally, a
small percentage was successfully fertilized
and cell division ensued, but all died before
hatching. These experiments having failed,
the eggs, which are semibuoyant in sea water,
were taken by means of a tow-net and brought
to the laboratory. These too died before hatch-
ing. The methods of hatching employed were
those which are usually successful with other
species.
The study of the life history of Gambusia
was continued chiefly for the purpose of veri-
fying observations of previous seasons. In
connection with the study of fishes in relation
to the mosquito problem, it was found that
the common eel (Anguilla rostrata) may, at
least under more or less abnormal conditions,
be of value as an eradicator of mosquito lar-
ve, for small specimens taken from reservoirs
receiving the overflow of an artesian well were
found to have subsisted chiefly on mosquito
larvee, which in this instance constituted about
the only food available. These eels were not
confined in these reservoirs, but had come
there through choice by passing from salt
water through the overflow from the reser-
voirs, a passage which remained open for an
exit as well as an entrance. This then indi-
cates that the common eel should not be over-
looked in the study of fishes in relation to the
destruction of the mosquito. Several collect-
ing trips to fresh-water ponds and streams in
the vicinity of the laboratory yielded the fol-
lowing species of fishes which do not seem to
have been recorded from this immediate vicin-
ity; Ameiurus erebennus Jordan, Amewurus
catus (Linneeus), Hrimyzon sucetta (Lacé-
péde), Notemigonus crysoleucas (Mitchill),
Notropis procne (Cope), Dorosoma cepedia-
num (LeSueur), Hsox americanus Gmelin,
Esox reticulatus LeSueur, Aphredoderus say-
anus (Gilliams), Centrarchus macropterus
(Lacépéde), Chenobryttus gulosus (Cuvier &
Valenciennes), Enneacanthus gloriosus (Hol-
brook), Lepomis gibbosus (Linneus), Lepomis
incisor (Cuvier & Valenciennes), Microp-
terus salmoides (Lacépéde), Perca flavescens
Aveust 24, 1917]
(Mitchill), Boleosoma olmstedi (Storer), Cope-
landellus quiescens (Jordan). The two ma-
rine species, Synodus intermedius (Agassiz)
and Myrophis punctatus Liitken, appear to be
new to the Beanfort fauna.
Dr. Albert Kuntz, of the St. Louis University
School of Medicine, continued the study of the
embryological and larval development of fishes
carried on during several seasons. Experi-
ments in rearing larve gave only negative
results.
Dr. Kuntz also made a detailed study of the
skin of flounders adapted to backgrounds of
different colors for the purpose of determining
the degree of distribution of melanin and
xanthine pigment and the relationship of the
guanophores with the chromatophores when a
given shade or color is assimilated as nearly as
possible. Shade was found to depend primar-
ily on the degree of distribution of the me-
lanin pigment and the relationship of the gua-
nophores with the melanophore. Color depends
on a complex group of factors including the
relative degree of distribution of melanin and
xanthine pigment and the optical effects due
to the diffraction of light by the guanin crys-
tals in the guanophores.
Mr. Arthur Jacot, of Cornell University,
continued for the second season the study of
the life history of the mullets of the Beaufort
region. It was definitely determined that the
nominal genus Querimana comprises the
young of the genus Mugil. At acertain period
in their lives the young mullets pass through
a gradual change which gives them the full
adult characters. During this time the first
soft ray of the anal fin is transformed into a
spine, a change in the sculpture of the scales
giving the appearance of a winter line also
takes place, and the color is changed more
nearly to that of the adult. The “jumping
mullet” (Mugil cephalus) spawns in the fall,
from October to December. The young grow
rapidly and attain a length of 5 or 6 inches
when one year of age. Then they appear to
migrate southward by a slow and leisurely
movement. In the spring they migrate north-
ward, but by a more direct and apparently
more continuous run. This migration causes
SCIENCE
Wee
a cessation of feeding and therefore of growth
which is so marked as to affect the scale,
leaving a “migration line”? The jumping
mullet, as shown from these studies, normally
attains maturity when two years of age, but
it may continue to grow until at least five
years old. The “silverside mullet” (Mugil
curema) spawns in the spring and the young
grow rapidly. In the fall they leave the har-
bor to return only in small numbers. < SE >< er Sa 1H
This process, simple as it appears to the
teacher, is not so simple for the student, as it
really involves identifying ¢ as the number of
seconds the body has fallen, g as the number of
ft./sec.2 in the gravity acceleration, perform-
ing the computation and then interpreting the
result as a number of feet. One obvious cause
of trouble is the necessity for using certain
definite units on each side, with the errors
made by the use of the wrong units; and
another, perhaps not so obvious, is the fact
that the formula itself is not a statement
about a real distance of so many feet, a real
acceleration of so many ft./sec.” and a real
time of so many seconds, but about pure num-
bers, mere incomplete “so many s,” the most
abstract things yet invented by man. Under
these conditions is it surprising that a fresh-
man fails to formulate his data into mathe-
matical equations?
On the new plan, the equation is taken as
a statement about actual concrete things. In
this particular case, the computation would
take the form,
ft.
- X 3? sec.2 = 144 ft.
sec?
s=3X 32
The interpretation of the formula is now that
s is physically a result of the combination of
the gravity acceleration g with the time ¢,
which enters once in producing the final veloc-
ity gt, and mean velocity 4g¢ and again in
combination with this mean velocity to give
the distance 3gt?. The essential feature in
the application of this plan is the insertion of
each quantity as a quantity, that is, as so
many times another quantity of the same kind,
and not as a mere “so many.”
If in computation the boy should happen
to forget to square t, he would get
Re gnc 8 geo. ne ageeey,

an obviously impossible kind of answer. But
if he departs from the above method only in

calling {= zy min., he gets

= 3X 32
To reduce this to simpler terms he has only
to substitute 60? sec? for min?, exactly as he
would perform any other algebraic substitu-
tion of equals, and then cancel the sec? and
finish the computation. Or, if he lets

Qe hr. sec.’
he gets
s= 3X 22 =o X 3? sec.?
=O eee X 3? sec.2 = 25 min.,
which is as correct an answer as the other.
To reduce units the game is simply to substi-
tute equals for equals and cancel. If this does
not give the right kind of an answer, it is a
sure indication of an error.
Of course, to play the game fairly, we must
abolish formulas with lost units, such as s=
16¢#. Examples of these are found most fre-
quently in electricity. The old plan would
write such a formula as that for the force on
a wire in a magnetic field, as F—JIH with
a string of restrictions on units, or F¥ = =,11H
with another string. By forgetting the re-
strictions and using the simpler formula with
the most familiar units, the students often
achieve remarkable results. On the new plan
this would be written # = KIIH where
Sl te dyne
~ 10 amp. em. gauss.
and all restrictions are removed. It is of
of course true that this form of the equation
involves more writing than the others; indeed,
it may be noted here that the process of treat-
ing all equations as physical statements is
not necessarily worth while for trained men
doing routine computations, but it is extremely
useful for all sorts of cases where the com-
putations are not familiar enough to be clas-
sified as routine work. For all such cases it
is well worth while to write out the propor-
tionality constant, especially if some one is
likely to want 1, say, in inches or F in kilo-
grams.
Aucust 24, 1917]
In the detailed application of this principle,
there is one point where confusion might
arise, though it can readily be avoided. It
is the anomalous behavior of the unit, radian,
which appears as a perfectly respectable unit
when an angular velocity is converted from
TeV to see
min ra
but does not appear when the
Au Wk Vv ;
same angular velocity is found from = . This
anomaly is the only one of its kind, and is
not nature’s fault, but our own. If we de-
fine angle as degree of opening, to be meas-
ured in units of the same kind, the substitu-
tion method outlined above is the most nat-
ural method of converting say ETD xed) Tf
min sec
on the other hand, we define angle as a mere
ratio of are to radius it is necessarily a pure
number (like a sine or a tangent). If we
swap horses in midstream, we shall either
miss this unit later or else see it floating up
where we do not expect it. This means we
must insert or rub out the unit radian when-
eyer it is convenient to do so. Fortunately
angle is the only quantity treated in such a
way.
For the sake of such mathematical purists as
may not approve of the above on. philosoph-
ical grounds, a few words should be inserted
here on the meaning of the term “ multipli-
cation.” In elementary arithmetic it means
merely repeated addition, but with the intro-
duction of irrational numbers the term is ex-
tended by mathematicians to an operation
that is not strictly repeated addition. The
plan here advocated extends the notion of
multiplication still further, to cover a physical
combination of concrete quantities. In gen-
eral the definition of multiplication in each
individual case amounts to translating into
algebra the ordinary verbal definition of the
compound quantity involved (area, velocity,
work, ete.). This extension is made practic-
able by the fact that the operation thus de-
fined obeys the same logical postulates as the
corresponding algebraic operation on pure
numbers. In other words, the machinery of
mathematics can be applied not merely to
numbers, but to any group of concepts and
?
SCIENCE

operations satisfying the same postulates.
This fact is accepted intuitively by most stu-
dents; and incidentally the emphasis it puts
on the definitions prevents most of the well-
Inown confusion between acceleration and
velocity, power and work, and so on.
To sum up, it seems to me after several
years’ experience with this system, that it has
the following important advantages: (1) It
treats equations as neat shorthand statements
about real physical things and emphasizes the
esthetic side of mathematics in general; (2)
It provides an enlarged principle of dimen-
sions by which equations may be checked
during computation; and (3) It removes com-
pletely all restrictions on the units to be used
and enables the student to concentrate his at-
tention on the facts of nature without the dis-
turbing influence of arbitrary rules.

SPECIAL ARTICLES
ON THE SWELLING AND “SOLUTION” OF
PROTEIN IN POLYBASIC ACIDS
AND THEIR SALTS
THERE are available only scattered observa-
tions on the absorption of water by proteins
in the presence of various polybasic acids and
their salts. In order to obtain further experi-
mental data in this field, we undertook a
rather detailed study of this problem during
the past year: As examples of proteins, dried
gelatin dises and powdered fibrin were used.
For the polybasic acids we chose phosphoric,
citric and carbonic. In connection with the
swelling of gelatin, we studied also its “solu-
tion.” The general results of our experiments
may be summed up as follows.
I
The amounts of water absorbed by gelatin
from equimolar solutions of monosodium,
disodium and trisodium phosphate depend not
only upon which of these salts are present, but
upon their concentration. Gelatin absorbs
but little more water in a solution of mono-
sodium phosphate than it does in pure water.
190 r
In low concentrations of disodium phosphate,
gelatin swells decidedly more than in pure
water, but as these lower concentrations give
‘way to higher ones, the gelatin swells less and
less until, when sufficiently high concentrations
are attained, the gelatin swells decidedly less
than in pure water.
These same general truths may be stated for
trisodium phosphate, except that the absolute
amounts of water absorbed in solutions of this
salt are, at the same molar concentration,
decidedly higher than in the case of the di-
sodium salt. Low concentrations of trisodium
phosphate bring about much greater swelling
than higher ones. With progressive increase
in the concentration of the trisodium salt,
there is a progressive decrease in the amount
of swelling until a concentration is finally
reached in which the swelling is decidedly less
than in pure water.
Having studied in this fashion the relation
of swelling to type of salt and its concentra-
tion, we investigated next the amount of water
absorbed by gelatin in phosphate mixtures of
compositions varying from the extreme of
pure phosphoric acid on the one hand through
mono-, di- and trisodium phosphate to pure
sodium hydroxid on the other. These mix-
tures were made in different ways. Beginning
with pure phosphoric acid, we added succes-
sively greater quantities of sodium hydroxid,
or beginning with sodium hydroxid, we added
successively greater amounts of acid until the
theoretical neutralization had been accom-
plished; or we began with pure acid and re-
placed this with more and more of the mono-
di-, or trisodium phosphate until the opposite
extreme of a pure alkali was reached; or we
began with a definite concentration of any one
of the phosphates and added progressively
ereater amounts of either acid or alkali. The
results in all these expriments were practically
the same. In 24 to 48 hours the gelatin at-
tained its maximal swelling (practically).
When the amount of swelling is plotted on the
vertical and the changes in the composition of
the solutions from acid through the mixtures
of the mono-, di- and trisodium salts to pure
alkali on the horizontal, a curve, roughly V-

shaped, is obtained. Greatest swelling is ob-
served in the pure acid solution and least in a
solution consisting essentially of monosodium
phosphate. From this point on, there is a
gradual increase in the swelling of the gelatin
until the disodium salt is passed, when there
occurs a more abrupt rise until the trisodium
salt is reached, beyond which the curve rises
still more steeply until the sodium hydroxid
end of the series is attained.
The swelling of gelatin in monosodium, di-
sodium and trisodium citrate follows the same
general laws as its swelling in the correspond-
ing salts of phosphoric acid. Monosodium
citrate in all concentrations increases some-
what the swelling of gelatin over the amount
of swelling in pure water. The same is true
of low concentrations of disodium citrate.
But the higher concentrations of this salt de-
press the swelling to below that attained in
pure water. These statements also hold for the
trisodium salt. As we succeed in getting
more base into the citrate, there appears a
distinctly greater tendency to depress the
amount of water absorption.
In studying the amounts of water absorbed
in citrate mixtures varying between the ex-
treme, on the one hand, of pure citric acid,
through mono-, di- and trisodium citrate to
pure sodium hydroxid, we observed that the re-
sults (when amount of swelling is plotted on
the vertical and progressive change in compo-
sition of solution on the horizontal) yield a U-
shaped curve. Greatest swelling is obtained
in the pure acid, the amount of this swelling
decreasing progressively as we approach the
monosodium salt. From the monosodium to
the disodium salt the curve falls more gently,
until a minimal point is reached in a mixture
of about equal parts of monosodium citrate
and disodium citrate. From here on, the
curve rises gradually to the trisodium salt,
after which it ascends steeply as we pass
toward the extreme of the pure alkali.
We have also studied in this fashion the
effects of carbonate mixtures. As the sodium
bicarbonate in a pure solution of this salt is
gradually displaced by a molecularly equiv-
alent amount of sodium carbonate, and this
AvucusT 24, 1917]
in its turn by an equivalent of sodium hy-
droxid, the amount of water absorbed gradu-
ally increases in the form of the right arm of
the letter U. Swelling is least in the pure so-
dium bicarbonate, increases slowly in the so-
dium carbonate and then more rapidly as this
is replaced by sodium hydroxid. The swelling
of gelatin in pure sodium bicarbonate is
slightly higher, in the concentration employed
by us, than in pure water.
I
Practically the same findings as have been
detailed for gelatin in the paragraphs given
above were encountered when the swelling of
fibrin was studied in different concentrations
of the pure salts or in mixtures of these, vary-
ing between the extremes of acid on the one
hand and alkali on the other.
Il
It has been pointed out in previous papers’
that the swelling of a protein and its lique-
faction or “solution” are totally different
processes. The “solution” of gelatin is, in
other words, not merely the extreme or a con-
tinuation of the swelling of a protein. We
were able to verify these results in studying,
in parallel with the swelling of gelatin in poly-
basic acids and their salts, its “solution ” un-
der the same circumstances.
When gelatin containing a unit amount of
water, and solid at ordinary room tempera-
ture, has mixed with it phosphoric acid, phos-
phate mixtures or sodium hydroxid in the
concentrations already discussed above, it is
found that the “solution” or liquefaction of
the gelatin parallels its swelling. In other
words, gelatin remains solid in phosphate mix-
tures of various kinds, but tends to lose in
viscosity, to liquefy and to remain fluid as we
pass from the phosphates in the direction
either toward acid or toward alkali.
IV
We hold these experiments to be corrobora-
tive of, and to bear upon notions previously

expressed regarding the importance of acids,
of alkalies, of various salts and of these in
mixture in determining the amount of water
absorbed by protoplasm under physiological
and pathological conditions. The well-estab-
lished qualitative and quantitative analogy
between the absorption of water by various
hydrophilic colloids (like the proteins) and
isolated cells, organs or organisms, whether of
animal or vegetable origin, shows that proto-
plasmie water absorption is essentially a
colloid-chemical phenomenon. These studies
with polybasie acids and their salts therefore
bring further proof of the importance of an
abnormal production or accumulation of acids
within such colloid systems for increasing the
amount of water thus held, and so of explain-
ing the mechanism by which the abnormally
high hydrations of living cells are brought
about as observed in edema, excessive turgor
and plasmoptysis, or in those various “ dis-
eases” which are in essence only edemas of
the involved organs like nephritis, glaucoma
and “uremia.” These experiments also show
how coincident with, but not synonymous with
the increased swelling there also occur a “ soft-
ening”? and an increased “solution” of the
colloids of the involved tissues, thus explain-
ing further the “softening” of organs after
an initial swelling together with the appear-
ance of increased amounts of colloid (like pro-
tein) in the fluids bathing or expressed from
the involved edematous tissues (albuminuria,
excessive protein content of spinal fluid in ede-
mas of the central nervous system, increased
protein content of serous accumulations, etc.).

NOTES ON MITES ATTACKING ORCHARD AND
FIELD CROPS IN UTAH?
Durine the summers of 1915 and 1916 while
making investigations for the laboratory of
the American Smelting & Refining Company,
Department of Agricultural Investigations, I
found certain mites to be particularly abun-
dant and destructive to grains in Utah.
The most important of these was the com-
mon Tetranychus bimaculatus Harvey, which
Ewing believes is the same as 7’. telarius Linn.
The host list for this species, as Ewing has
pointed out, is a long one, and it is an impor-
tant pest on a surprisingly large number of
crops. In 1916 it was so abundant in orchards
that many cherry trees were completely de-
foliated before the end of August, and apricot,
pear, plum and apple trees were only a little
less seriously affected. Raspberry and currant
bushes suffered severely, some of them losing
all of their leaves. Peas, beans, tomatoes and
other kinds of garden truck showed more or
less injury in all stages of their development,
and in one field of sugar beets, I found many
leaves drying and turning brown on account of
the attacks of this mite. The loss of the
foliage of many ornamental plants, while not
of so much economic importance, was, of
course, a very annoying thing.
Corn probably suffered more than any other
field crop. In many fields practically every
plant suffered the loss of some of its leaves,
and in other places all of the leaves turned
brown and became thoroughly dry because of
the presence of the myriads of mites that
covered the undersides of the leaves. The
parts of the fields where the soil was lighter
and dryer usually suffered most, but no parts
seemed to be immune from the attacks of this
pest. The suckers and lower leaves were the
first to be attacked and to show the brown
spots or streaks where colonies of the mites
were feeding. When the trouble went no fur-
ther it was of but little economic importance,
but when the upper leaves were attacked and
practically all destroyed the plant withered and
was not even good for fodder. 7

Many wheat fields also sustained consider-
able losses due to the attacks of the same mite.
The wheat plants would usually be attacked a
short time before the head burst from the
sheath and when the infestation was bad the
leaves would become dry and brown at the
point of attack and the portion of the leaf
beyond this would droop down and dry out.
Often all of the leaves would be affected in
this way and the heads, if they developed at
all, would be small and poorly filled.
Earlier in the season, while the wheat plants
were much smaller, they were often attacked
by two other species of mites. One of these
is the well-known clover mite, Bryobia pra-
tensis. The other has been called the jumping
mite on account of its habit of quickly fold-
ing its legs and dropping from the plant when
disturbed. Banks in Proc. Ent. Soc. Wash.,
Vol. 14, p. 97, named this species Tetranychus
longipes. A letter dated June 29, 1915, says
that he now places it with two others in a new
genus, Tetranobia. He refers to this genus
again in his bulletin on “The Acarina or
Mites” (Rept. No. 108, U. S. Dept. Agric.
Office of Sec., pp. 83 and 38) but the formal
description of the genus has not yet been pub-
lished. The common name, jumping mite, is
somewhat misleading, for the mite does not
actually jump, but, when alarmed, it folds its
legs quickly and may thus be thrown a short
distance from the spot where it was feeding.
In fields where the mite is abundant the
leaves turn distinctly gray and many of them
become so dry that the growth of the plant is
seriously affected. Both B. pratensis and
Tetranobia longipes were found destructively
abundant not only on wheat, but on barley,
oats and many wild grasses.

THE OCCURRENCE OF MANNITE IN SILAGE
AND ITS POSSIBLE UTILIZATION IN THE
MANUFACTURE OF EXPLOSIVES
Durineé the course of our investigations on
the fermentation processes that occur immedi-
ately after the ensiling of corn, and the chem-
ical products resulting therefrom, it was found
August 24, 1917]
that mannite could be isolated from practically
every sample of normal corn silage. The alco-
holie extract from dried silage yielded, on
evaporation, considerable amounts of mannite,
which after one recrystallization gave the
characteristic crystals melting at 168-169°.
That the presence of mannite can not be con-
sidered a local phenomenon is shown by the
fact that silage samples obtained from a num-
ber of other states in the middle west all con-
tained mannite. The only previous reference
to the occurrence of mannite in silage is in
a paper by Manns,! published a quarter of a
century ago. In his work, however, only one
sample of silage was examined and the ap-
proximate amount of mannite found was not
stated.
The following table shows the amount of
mannite actually isolated by us from samples
of silage obtained from various sources:

Tt will be noted that the highest percentages
of mannite are to be found in the sunflower
silage, the cane silage and the experimental
corn silage to which sucrose had been added.
Evidently the mother substance of the man-
nite is sucrose, or more specifically its fructose
moiety.
The production of mannite no doubt reaches

a maximum soon after filling the silo and then
some loss probably occurs, owing to further
bacterial activities. However, the amount of
mannite is still considerable when the silage
is several months old.
If it is desired to prepare quantities of man-
nite without reference to an approximately
quantitative yield, the method may be much
simplified. The silage is put in a powerful
press, the juice filtered, evaporated to about
one sixth of its volume and two or three vol-
umes of alcohol added. The mannite then
erystallizes out, and the alcohol can be recov-
ered in the usual way. In this manner it
should be possible to extract the mannite on a
large scale at very little cost. The pressed
residue and the mother liquor could be com-
bined and used for feeding in place of the orig-
inal silage, since practically nothing would be
removed but the mannite and the volatile acids.
Mannite yields a nitration product very
similar in properties to nitroglycerin. Accord-
ing to Sanford,? “ Nitromannite is more dan-
gerous than nitroglycerin, as it is more sensi-
tive to shock. It is intermediate in its shat-
tering properties between nitroglycerin and
fulminate of mercury. ... It is not manufac-
tured upon the commercial scale.”
The reason nitromannite is not made com-
mercially is probably the prohibitive cost of
mannite. Prepared by the above method from
silage, mannite should be even cheaper than
glycerin, especially if the residues are utilized
as cattle feed. The thousands of tons of silage
used every year by the farmers of this country
could be made to yield a valuable by-product if
treated by this simple process.

committee met, passed on the report of the secre-
tary-treasurer, elected 10 new members, and se-
lected the State Normal College, Greensboro, as
the next place of meeting. At 3 P.M. the reading
of papers was begun and continued until 5:30,
when adjournment was had. MReconvening at 8
P.M., the academy was welcomed to the university
by Dean Andrew H. Patterson, after which Presi-
dent F. P. Venable, of the academy, delivered his
presidential address, ‘‘The structure of the
atom.’’* Next Professor Collier Cobb gave a lee-
ture on ‘‘ Typical early maps of North Carolina’’
illustrated by lantern slides of some of the maps
in question. The academy then adjourned to the
hospitable home of Professor W. C. Coker for a
highly enjoyable smoker.
The annual business meeting of the academy was
held at 9:15 Saturday morning. Reports of the
secretary-treasurer, the executive and other com-
mittees were made. On motion a committee was
appointed to cooperate with a similar committee
from the Science Section of the North Carolina
State Teachers’ Association in studying the sub-
ject of the teaching of high-school sciences in the
state with reference to its increased efficiency.
The secretary reported on his visit to the meeting
of the Southern Association of Colleges and Sec-
ondary Schools and his appearance in behalf of
the work in science before its committee on the
curriculum of secondary schools. On motion, the
secretary was again appointed as the representa-
tive of the academy at the next meeting of this as-
sociation. After some discussion it was declared
the sense of the meeting that an increased effort
be made in 1918 to bring into the membership of
the academy as many as possible of the high-school
teachers of science in the state.
The following officers were elected for 1917-18:
President—W. A. Withers, State Agricultural
and Engineering College, West Raleigh.
Vice-president—J. H. Pratt, University of North
Carolina, Chapel Hill.
Secretary-treasurer—E. W. Gudger, State Nor-
mal College, Greensboro.
Additional members executive committee—Bert
Cunningham, High School, Durham; H. R. Totten,
University of North Carolina, Chapel Hill; H. C.
Beardslee, Asheville School, Asheville.
At 10:50 a joint meeting was held of the acad-
emy and the North Carolina Section of the Ameri-
can Chemical Society for the reading of the papers
of common interest to both bodies. Following
this, papers were read before the academy until
the program was finished at 1:40, when the mem-
SCIENCE
[N. S. Vou. XLVI. No. 1182
bers were entertained by the university at
luncheon in Swain Hall. Of the 20 papers on the
program not one was read by title. Counting the
10 new members, the total membership of the acad-
emy is 84, of whom 37 were present at this meet-
ing. Including the presidential address, which will
be published in the current number of the Journal
of the Elisha Mitchell Scientific Society, the fol-
lowing papers were read:
Pliocene deposits in Orange county: JOHN E.
SMITH.
These occur on the divides and on the higher
terraces in the plateau section of the county and
generally over the Triassie area except on the
floodplains and on the steeper slopes near the
streams.
On the upland (elevation, 500-600 feet) this ma-
terial consists of smooth, rounded pebbles and
eobbles (some of which are polished) of quartz and
quartzose minerals up to six inches or more in
diameter, together with fragments of the same and
of other minerals down to the size of soil particles.
In the Triassic area (elevation, 250-400 feet) the
deposit comprises gravel, sand and soil (in addi-
tion to the above) in some places reaching a thick-
ness of a foot or more. This material has been
transported from a distance and characterizes the
Granville soils, distinguishing them from those of
the Penn series, which are derived from the Tri-
assic rocks in place.
The thinly distributed pebbles on the higher di-
vides of the county may be remnants of river de-
posits on a peneplain, but the soils, ete., of the
lower interstream areas are doubtless of Lafayette
age. (Illustrated with lantern slides.)
The pollination of Rotundifolia grapes: L. R.
DETJEN.
A close examination of the flowers of Vitis
rotundifolia brings out the fact that this species of
grape is not at all adapted to cross-pollination by
means of the wind; on the contrary, it seems to in-
dicate that insects alone are responsible for the
transportation of the pollen. Bees of the family
Andrenide and beetles of the species Chauliog-
nathus marginatus were tested for their propensi-
ties of transporting pollen and for the searching
for flowers of the fruit-bearing varieties.
The test was made by enclosing insects, newly
captured on flowers of staminate vines, separately
in spacious cloth bags together with clusters of
open but unpollinated flowers. The results se-
cured substantiate the hypothesis of insect pollina-
tion. They further indicate that bees of the fam-
Aueust 24, 1917]
ily Andrenide are probably the most effective
pollinators of the vine and that beetles are of only
minor importance. Bees of the family Mega-
chilidw are also active workers and undoubtedly:
contribute considerably toward the production of
fruit.
Saprolegnia anisospora in America: W. C. CoKER.
This species has not before been reported in
America. We have found it twice in Chapel Hill,
in marshy shaded places containing alge. It is dis-
tinguished chiefly by the following characters:
1. The presence of spores of two or three sizes,
borne usually in separate sporangia without re-
gard to the size of the latter; the small spores
from 10.5-11 4 in diameter, the large ones from
13.7-14.8 « in diameter. In nearly all cultures
there are formed a few very large spores, at least
twice the size of the ordinary large ones, these ap-
pearing mixed in with the latter.
2. The irregular shape of the sporangia, which
are not evenly cylindrical, but more or less waved,
bent and constricted, and which proliferate either
laterally from below as in Achlya, or within the
old ones, as is usual in Saprolegnia.
3. In sexual reproduction numerous oogonia are
formed, each with one or more antheridia of di-
clinous origin.
The jaws of the great barracuda, Sphyrena barra-
cuda: E. W. GuDGER.
A careful description, illustrated by photographs
and a specimen, was given of the teeth and jaws of
this fish. Their use was briefly described and
some accounts of the ferocity of the fish narrated.
In the waters of southern Florida it is generally
more feared than the shark, being bold and in-
quisitive where the shark is cowardly. The data
presented are part of a paper now in press in a
volume of memoirs from the Tortugas Laboratory
of the Carnegie Institution at Washington.
The status of the science work in the high schools
of North Carolina (lantern): S. J. Marton.
This survey and report will be published in full
in the forthcoming issue of the North Carolina
High School Bulletin.
Armillaria mellea, Clitocybe cespitosa, Pleurotus
sapidus and Claudopus nidulans in pure culture:
H. R. Torren.
The fact that the spores of Armillaria mellea
and Clitocybe cespitosa (C. monodelpha) have two
walls, while the spores of Plewrotus sapidus and
Claudopus nidulans have only one wall is plainly
shown in the sprouting spores. Mycelia of the
four mushrooms were shown in pure culture on

several media, also drawings of the mycelial
threads as seen under high power. Armillaria
mellea forms a slow-growing, closely flocculent,
cream-colored mat, and soon produces long, brown
to black, root-like rhizomorphs. In agar these
rhizomorphs are beautifully shown radiating from
the mat-like central mass. The mycelium of
Clitocybe cespitosa is much like that of Armillaria
mellea, but the threads are not so closely woven
and the rhizomorphs, or root-like bodies, are
white. Itis shown that Armillaria mellea and Clito-
cybe cespitosa, while very closely related, are not
the same. The mycelium of Claudopus nidulans is
silkier and is from white to pink in color. The
mycelium of Plewrotus sapidus except in old cul-
tures is loose and silky and is very fast growing,
soon covering the medium with a mass of pure
white threads. Fruiting bodies of both Pleurotus
sapidus and Claudopus nidulans were shown de-
veloping in pure cultures.
Structural geology of Orange county, N. C.: JoHN
E. Smiru.
With few exceptions the rocks of this county
occur in long, narrow belts and ‘‘islands’’ extend-
ing north 65° east. Named in their order from the
southeast these areas comprise the Triassic sedi-
mentaries, granite, diorite, rhyolite, schists and
greenstone, diorite, schists and phyllite, green-
stone and schists, diorite, schists and greenstone,
diorite, granite.
The structure of these rocks is that of a syncline
whose trough centers along the line of strike and
passes near Cheek’s Siding about three miles east
of Mebane. Measured along the dip this syncline
is approximately twenty miles wide and probably
contains folds of minor importance within it. The
major joints, flow lines, ete., of the igneous rocks
in many places parallel both the dip and the
strike of the schists belts. Inclusions of the
diorite in the granite attest the greater age of the
former and the presence of belts of igneous rocks
beneath the margins of the syncline certify their
contribution to the structure and prove the greater
age of the schists, ete. South of Chapel Hill be-
yond Morgan Creek the strike is due east and west
and the conglomerates, slates and rhyolites dip to
the south at an angle of 65°. (Mlustrated with
maps, charts and structure sections.)
State regulation of the sale and manufacture of
gas: C. W. EDwarps.
In 1910, out of 228 cities in the United States
of more than 25,000 population, only 47 had no
requirements such as are in a bill proposed for
North Carolina. Of these 228 cities, 103 are
196
under state laws and have no additional municipal
regulations. A number of cities such as Baltimore,
Buffalo, Los Angeles and Milwaukee have local
provisions in addition to state laws. In 1910, six-
teen states had laws providing for the state inspec-
tion of meters and of the purity of gas—Connecti-
eut, Georgia, Kansas, Maryland, Massachusetts,
Nevada, New Hampshire, New Jersey, New York,
Ohio, Oklahoma, Vermont, Virginia, Washington,
Wisconsin and California (B. of S. Cireular No.
32). Doubtless the list is now larger.
In 1910 the net income to the state of Massa-
chusetts in meter-testing alone was over $5,000.
The total cost of the tests on quality, purity, pres-
sure, etc., was assessed on the operating companies
according to their sales. Meter-testing is on the
fee basis. There is no good reason why such a de-
partment in North Carolina would not yield a
revenue to the state.
That the Corporation Commission in North Caro-
lina should have the power and machinery at its
command to protect the interests of citizens seems
obvious for the following reasons: Under existing
law it is the duty of the commission to regulate
the rates to be charged by gas companies. The
proper price is determined in a large measure by
the quality of product sold and this is almost at
the will of the producer. Gas in New York City
furnishes 680 heat units per cubic foot and is sold
at 80 cents. Gas in Durham furnishes at times less
than 500 heat units and is sold at $1.50. In one
city in this state gas furnishing 412 heat units sold
for $1.60. The standard requirement in regulated
states is around 600 heat units. The difference in
quality means a loss of from five to twenty thou-
sand dollars per year to consumers in various
towns of this state and the loss would easily run
into hundreds of thousands to the state at large.
While it may be to the interest of certain com-
munities to sell a cheap, poor gas it is safe to say
that it is always against public interest to have a
cheap, poor gas sold at a rich, high price. To
fairly meet its responsibility the commission must
know from its own tests the quality of the product
sold. The consumer is entirely helpless.
Aside from the question of rates, the public is
vitally interested from the standpoint of health.
In the method of manufacture used by one com-
pany in this state, carbon monoxide and hydrogen
are produced in equal quantities. Both of these
gases are odorless and one is a deadly poison.
Combined they give a cheap gas furnishing about
300 heat units. This gas causes a meter to register
just as fast as a 600 heat unit gas. It is the duty
SCIENCE
[N. 8. Von. XLVI. No, 1182
of this company to carburet this gas with an oil
which not only brings its heat value to standard,
but gives it a very pungent odor that makes it
noticeable in case of a leak. In this town a series
of fatal accidents have occurred due solely to the
neglect of the service company. In other methods
other deleterious elements are introduced by eare-
lessness so that in all cases public interest de-
mands systematic testing under the authority of
the state.
It is just as reasonable to let manufacturers sell
anything called fertilizer without tests as to com-
position as it is to permit of the sale of untested
gas. Our duty to test meters is just as obvious
as our duty to test weights and measures.
The advantages resulting from such an act
would not even be principally with the citizen.
An expert employed by the state to travel from
plant to plant observing and testing, corrects ir-
regularities and errors in manufacture that may
mean thousands of dollars saved to the companies.
If ammonia appears in the gas it means that a
valuable by-product is being lost. So it is with
other errors of manufacture. The fact that meters
are tested by the state brings a feeling of confi-
dence to the consumer that is worth much to the
gas companies. Uniform, improved and econom-
ical manufacture brings new and profitable business
and this more than compensates for any costs in-
volved. :

Fred’s Soil Bacteriology
The exercises described in this book are arranged primarily for students of soil bacteri-
ology, soil chemistry and physics, and plant pathology. As far as possible the experi-
ments are planned to give quantitative results. It is truly a valuable laboratory manual
—worked out by a teacher and based on the student’s needs.

This electrometer, of the quadrant type, somewhat
similar to the Dolezalek design, has been developed by
Dr. Karl T. Compton and Dr. Arthur H. Compton at
Princeton University.
The instrument is highly sensitive (0-50,000 mm. per
volt), needle and quadrants are well insulated, the capacity
is exceptionally small (about 15 cm.) and the reflections
are proportional to the voltages throughout a very wide
range. A conducting quartz suspension is used, which
yields a period of 2 to 5 seconds at low sensitivities. It
is practically dead beat.

LIEBIG’S LAW OF THE MINIMUM IN
RELATION TO GENERAL BIOLOG-
ICAL PROBLEMS1
Tue Law of the Minimum has never been
accurately defined, although the idea that it
involves is relatively simple. Professor B.
HK. Livingston says in a recent paper? that
‘‘this principle is still quite incomplete log-
ically and its statement will assuredly be-
come much more complex as our science
advaneces.’’ In order to get a clear under-
standing of the law so that it may be stated
accurately, we will begin with a simple
application to chemical reactions.
One molecule of KOH reacts with one
molecule of HCl to form one molecule of
KCl and one of H,O. If only one molecule
of KOH is present, only one molecule of
KCl can be formed, no matter how many
molecules of HCl are present; and likewise
if only one molecule of HCl is present, only
one molecule of KCl can be formed, no mat-
ter how many molecules of KOH are pres-
ent. By considering the weights of the
reacting substances, the situation is some-
what complicated: 56.1 grams of KOH
react with 36.5 grams of HCl to form 74.6
grams of KCl and 18 grams of H,O. In
round numbers 3 parts by weight of KOH
and two of HCl give 4 parts by weight of
KCl and one of H,O: 3/4 gr. of KOH and
1/2 gr. of HCl are necessary to form a gram
of KCl. Let us call these fractions, 3/4 and
1/2, the specific reactive weights of KOH
and HCl in respect to the formation of a
unit quantity of KCl. Suppose « amount
of KOH and y of HCl are given. If x and

University, April 19, 1917.

198
y are divided by their respective specific
reactive weights, we get 3% and 2y. The
smaller of these quantities is a direct meas-
ure of the weight of KCl that can be
formed from « KOH and y HCl. If, for ex-
ample, + and y are both equal to three
grams, four grams of KCl can be obtained.
These facts can be generalized. If A, B
and C are substances which react to form S
and u A, v B and w C are necessary for the
formation of a unit amount of S, then u, v
and w may be called the specific reactive val-
ues of A, B and C, respectively. They may
be weights, volumes, numbers of molecules
or what not. In any particular case, where
pA, qB and rC are reacting, the amount of
S formed is the smallest of the fractions
p/u, q/v, r/w. When the amounts of the
reacting substances are divided by their
specific reactive values, the smallest quan-
tity so obtained is equal to the amount of
the product formed.
This conclusion is directly applicable to
the problem of fertilizers. It is known that
most of the higher plants must obtain
seven elements in combined form from the
soil. They are S, P, N, K, Ca, Mg and Fe.
If aS, BP, yN, 5K, «Ca, (Mg and 7Fe are
required for a unit amount of growth in
some particular plant, say wheat, and if
aS, bP, cN, dK, eCa, fMg and gF e are pres-
ent in a particular soil in available form,
the maximum amount of wheat that can be
grown in that soil will be the smallest of
the fractions a/a, b/B, c/y, 4/8, e/e, f/E,
g/y. In this case a, B, y, ete., may be called
specific growth values for the plant under
consideration. When the available amounts
of the essential inorganic food constituents
are divided by their respective growth
values, the smallest quantity obtained gives
the maximum amount of growth possible.
It was in this connection that Liebig® first

tur und Physiologie,’’ 7*® Auflage, 2: 225, 1862.

[N. 8. Vou. XLVI. No. 1183
formulated the Law of the Minimum which,
as commonly stated,* says that ‘‘the yield
of any crop always depends on that nutri-
tive constituent which is present in mini-
mum amount.’’ The use of the term mini-
mum is not strictly accurate, as can be seen
from the example of KOH and HCl. If
three grams of each are present, the amount
of KOH determines the yield of KCl, al-
though both HCl and KOH are present in
equal amount. However, the above state-
ment of the law is convenient because of its
simplicity.
A much broader application of the Law
of the Minimum was indicated by the work
of F. F. Blackman, whose conclusions are
summarized in his paper on ‘‘Optima and
limiting factors.’’> Blackman called atten-
tion to the complexity of the process of car-
bon assimilation, the rate of which depends
on at least six factors—
1. Temperature,
. Light intensity,
. Carbon-dioxide supply,
. Water supply,
. Chlorophyll,
. Enzymes.
Q oP ow bo
Where it is possible to vary one of these
factors independently of the rest, its effect
on the rate of assimilation can be measured,
under suitable conditions, and a curve
plotted. In this way a temperature-as-
similation curve, a light-assimilation curve
and a carbon-dioxide-assimilation curve
can be constructed. The other factors
are more difficult to control. The fol-
lowing curves were constructed by Black-
man and Smith® from a study of the
rate of assimilation in Elodea.
The light curve and the carbon-dioxide
curve are straight lines. The rate of as-
similation varies directly with the inten-

sity of light and the supply of carbon di-
oxide. The temperature curve shows that
the rate of assimilation is an exponential
function of the temperature. In fact the
process of assimilation obeys van’t Hoff’s

law of reactions for temperatures under
30° C. Above this, the rate of assimilation
at first rises and then falls off, the process
being complicated at high temperatures by
a ‘‘time factor.’’ The same effect has been
observed at high light intensities, and with
strong concentrations of carbon-dioxide
which have a narcotic effect.
Disregarding these complications, we
will confine our attention to the first parts
of these curves. The ordinates of all three
curves are the same, namely, rates of carbon
assimilation, which can be measured in
terms either of CO, absorbed or of sugar
produced. The former happens to be the
more convenient measure. At any given
temperature, the rate of assimilation which
is a function of that particular temperature
can be determined directly by the curve and
is equal to a certain distance measured off
from the origin on the Y-axis. Similar dis-
tances are given for any definite supply of
carbon dioxide and for any degree of il-
lumination. In any actual environmental
complex, where the temperature, light and
earbon-dioxide supply are known, the rate
SCIENCE
199
of assimilation is equal to the shortest dis-
tance measured on the Y-axis. This is
stated as a general principle by Blackman
as follows: ‘‘When a process is conditioned
as to its rapidity by a number of separate
factors, the rate of the process is limited
by the pace of the ‘slowest’ factor.’’ The
factor which gives the shortest distance on
the Y-axis—that is, the ‘‘slowest’’ factor,
he calls the limiting factor.
As a matter of fact the carbon assimila-
tion of green plants is usually limited by
the seasonal variation in temperature and
the diurnal variation in light, the CO, con-
tent of the air being constant. Nothing has
been said of the other factors that effect
carbon assimilation—the water supply,
chlorophyll and enzymes. These so-called
‘“internal’’ factors, as well as the ‘‘exter-
nal’’ factors, are governed by the Law of
the Minimum. Of the internal factors,
water and chlorophyll are present in ex-
cess in healthy green plants, the amount of
assimilatory enzymes being the only prob-
able limiting factor.
It is not necessary to adduce additional
examples to show that the Law of the Mini-
mum is a universal law, affecting not merely
the concentration of reacting substances,
but all factors that in any way influence a
reaction or process. The law is applicable
to physical, chemical and geological as well
as biological problems.? An interesting in-
stance of its application to a problem in
physics is the determination of the magni-
tude of a thermionic current. This varies
with changes in temperature, and also with
changes in the voltage applied. The tem-
perature formula gives one value, the vol-
tage formula may give another; the lesser
value determines the current flowing. The
7A timely application may be made which is
worth bearing in mind. The efficiency of a nation
at war is subject to the Law of the Minimum.
Defeat, in the last analysis, may be attributed to
the effect of some limiting factor.
200
application of the Law of the Minimum
has been worked out in many cases and has
been of great use in the interpretation of
complicated relations; but it has been rec-
ognized as a law and has been consciously
applied by plant physiologists and physio-
logical chemists only. Without doubt it
can be used to advantage in many problems
of the physiology, morphology and ecology
of both plants and animals.
The Law of the Minimum must be taken
into account in all experimental work, for
which it serves both as a precaution and a
guide. When investigating the effect of
an external factor such as temperature,
light, ete., on any given process, it is neces-
sary to keep all other variable factors con-
stant, and then to determine the effect of
‘changes in the factor under consideration.
What results might be obtained when this
method is used in studying carbon assimila-
tion? Suppose the CO, supply and the
light are kept constant, while the tempera-
ture is varied. If the CO, supply is such
that it becomes a limiting factor when the
temperature rises above 10° C. then the
rate of assimilation will rise with the tem-
perature up to this point, but will remain
constant at all higher temperatures, until
the destructive effect of the high tempera-
ture is manifested and the curve again falls
off. Above 10° C. variations in the tem-
perature have no apparent effect under
these experimental conditions. But if the
CO, supply is increased so as to permit
more rapid assimilation, then the tempera-
ture curve can be extended. Negative re-
sults from such an experimental method
are therefore without significance. It is not
enough that the experiment be conducted
under constant conditions; the constant
factors must not interfere in any way with
the carrying out of the process ; that is, they

must not be limiting factors. On the other
hand, it is a simple matter to determine by
the shape of the curve whether any other
factor than the one under investigation is
a limiting factor. Such is always the case
when a break occurs in the curve; usually
the curve rises at first and later runs paral-
lel with X-axis. Such curves were obtained
by Miss Matthaei?? in studying the
carbon assimilation of cherry laurel at
varying temperatures with unit light inten-
sity. The problem is much more compli-
cated, however, when variation of one factor
is accompanied by changes in one or more
other factors. This complication arises in
plotting the temperature curve for enzyme |
activity. The curve rises at first according
to van’t Hoft’s law of reactions, but even-
tually a maximum value is reached and the
curve falls off. At some point near the end
of the ascending portion of the curve a

break occurs: for all temperatures below
this point, temperature is the limiting fac-
tor and determines the activity of the
enzyme; for all temperatures above this
point, not temperature, but the amount of
enzyme is the limiting factor. The higher
temperatures cause a permanent inactiva-
tion or decomposition of the enzyme so that
its activity is conditioned only secondarily
by the temperature. There is also a time
factor involved here; the longer the tem-
perature acts, the more the enzyme is de-
composed, within certain limits. The study

Auveust 31, 1917]
of the action of salt solutions on permea-
bility, growth, ete., involve even greater
complications produced by the interrela-
tion of conditioning factors.
In order to get an accurate statement of
the Law of Minimum, it is necessary to
get away from the custom of discussing
causes, however difficult this may be."
The idea of causation invariably indicates
incomplete analysis. A biological phenom-
enon is dependent not on a single variable,
but on a complex or constellation of factors,
as we have seen in the case of carbon as-
similation. It should be discussed there-
fore in terms of all the conditioning fac-
tors, not in terms of that one which tempo-
rarily happens to be a limiting factor. The
term ‘‘function’’ is valuable in this con-
nection. The amount of carbon assimila-
tion is a function of the temperature; it is
another function of the illumination, ete.
With this idea of function in mind, the Law
of the Minimum may be stated in the fol-
lowing form. When a quantity is depend-
ent on a number of variable factors and
must be a function of one of them, the
quantity is that function which gives the
minimum value. Expressed in plain Eng-
lish this means that a chain is no stronger
than its weakest link. The Law of the
Minimum is only too obvious. Its applica-
tion is often so self-evident that it is made
as a matter of course.
But the most interesting thing about the
law is not how it works, but when it does
not work. There is a fundamental discrep-
aney between the Law of the Minimum and
Galton’s Law of averages. In the current
text-books on genetics and plant physiol-
ogy’ the following ingenious explanation
of Galton’s Law is given. Assume that the

size of a bean is determined by only five
variables, each of which must occur in one
of two categories ; in one case the size of the
bean will be increased by one unit of size,
in the other it will be decreased by the same
amount. Considering all the possible per-
mutations of these five variables, we get the

The beans will be of six sizes, + 5, + 3,
+ 1,—1,—8,—5, and out of a very large
number (n), 2/32 will be + 5, 5n/32 will
be + 8, 10n/32 will be +1, 10/32 will be
—1, 5n/32 will be —38, and n/32 will be
—5. The six sizes are in the ratio
1:5:10:10:5:1. If we plot the sizes of
the various classes of beans against the fre-
quency of their occurrence, we get an ap-
proximation to the familiar curve of nor-
mal error. For the sake of simplicity, the
number of variable factors was made five
and the number of categories in which each
might occur was limited to two. If the
variables and the categories are made suffi-
ciently numerous, the curve of normal error
can be approximated within any desired
degree of exactitude. It is unnecessary to
point out the empirical fact that when the
sizes, weights, ete., of organisms or their
parts are divided into classes and the
202
classes are plotted against the number of
individuals in each class, the resulting
curve approaches the normal curve of error,
if a sufficiently large number of individ-
uals are used. Exceptional instances of
curves with more than one maximum, or
only parts of curves, are easily. accounted
for and for convenience will be left out of
consideration. Since the empirical data
bear out the conclusions arrived at by the
above procedure, the explanation may be
considered valid.
However, the explanation involves the
addition of the values of the various fac-
tors, which is in reality averaging them,
since their value is measured in terms of
net gain or loss. Although this process of
averaging the various factors involved is
borne out by comparing the results with em-
pirical data, it is done, nevertheless, in con-
tradiction to the Law of the Minimum. Ac-
cording to this law n/32 should be +1 and
31n/32 should be —1, because all the fac-
tors are + 1 in only one permutation, and
—1 oceurs in all the others and would be
a limiting factor. The curve that would
result if the Law of Minimum held would
start from one at the upper end of the
seale of sizes, weights-or what not and
would rise with great rapidity toward the
lower end, where it would reach its maxi-
mum. This kind of curve is not the rule.
Every case where Galton’s Law holds is
a case where the Law of the Minimum does
not hold. The resultant size or weight of
an organism, which is a measure of its
growth, shows that this is not determined
by the limiting factor of its environment,
but represents some sort of average between
all the factors involved. In other words, a
process of compensation or integration has
taken place, the factors giving the largest
values being utilized to some extent at
least to alleviate the influence of the limit-
ing factor—a utilization of surplus to cover
deficit. Individual processes obey the Law
SCIENCE
[N. S. Vou. XLVI. No. 1183
of the Minimum; but the grand total is
governed by what may be termed a prin-
ciple of integration.
The means by which this integration is
brought about are not hard to find. At
least four important processes are at work
in living organisms to this effect, namely—
1. Responses to stimuli,
2. Development,
3. Evolution,
4. Biotic succession.
A few examples will illustrate the way in
which integration is effected by each of
these. A seedling placed upside down is in
the wrong position with respect to the cen-
ter of the earth, its source of light, and mois-
ture. Position with respect to gravity may
be considered to be the limiting factor
here; but the germinating rootlet is posi-
tively geotropic and bends toward the
earth; the young shoot is negatively geo-
tropic and bends away from the earth. In
this way these responses to the geotropic
stimulus counteract the influence of the
limiting factor. Roots behave similarly in
response to moisture content of the soil;
stems and leaves in response to light.
In plants it is hard to draw a line be-
tween simple responses to stimuli and
morphogenic responses which involve per-
manent changes of form and structure.
The difference between sun leaves and
shade leaves is a familiar example of a
morphogenic response. The shape, size and
structure of the leaf here counteract the
limiting factor light. Again, plants which
are shaded by others so that they receive
insufficient light usually become etiolated,
that is, the stems and leaf-petioles in many
cases increase in length until some portion
of the plant is brought to a position where
it receives adequate illumination. Here
again the limiting factor is light, and the
result of etiolation is to overcome its effect.
Evolution is likewise an integrating
process. Its results are not accomplished
Aveust 31, 1917]
in the individual, but in the race, and are
called adaptations. Adaptations are means
of avoiding the effects of limiting factors.
Another means of integration is seen in
biotic succession. Here the integration ex-
tends over a considerable period of time
and its benefits do not accrue to the individ-
ual or the race, but to succeeding genera-
tions and different species. The integra-
tive effect in succession may be largely pro-
duced by the death and decay of an asso-
ciation resulting in the accumulation of
humus. Thus both xerophytie and hydro-
phytic plants prepare the way for a meso-
phytie flora. The limiting factor here is
water, which is too scarce in the one case
and too abundant in the other. By the ac-
cumulation of humus, the properties of the
soil are so altered that a more favorable
water supply is offered to later generations,
and in this way the effect of the limiting
factor is counteracted.
All these processes which bring about
integration between the relations of living
organisms to the factors of the environment
that determine their growth and activity
are evidently based on a single fundamental
principle, to which Professor L. J. Hen-
derson has applied the appropriate mis-
nomer teleology. Wherever integration
is found in the factors influencing the indi-
vidual, the race or the association, it is pos-
sible to define a closed system. Such a sys-
tem includes all the factors which can be
integrated, that is, all the possible limiting
factors for any given process. These sys-
tems may focus about a single cell, an
organ, an organism or a group of organ-
isms. They are inclusive. The life of a
plant, for example, is determined by a
complex of factors between which integra-
tion is found to occur. At the same time
the functional activity of the root system
is determined by another complex of inte-
erated factors, and the functional activity

of the leaves by still a different set. Since
the life of the root system is dependent on
the products of the activity of the leaves,
these represent members of the complex
which conditions the growth and function
of the root system. Such internal factors
as enter into the complex of factors cen-
tering about the life of a portion of an or-
ganism are likewise subject to integration.
In this way the condition of the root sys-
tem affects the leaves and the condition of
the leaves affects the root system. Correla-
tions are therefore manifestations of the
principle of integration.
The organic world can be analyzed into
systems of various orders, those of a higher
order being inclusive of, or divisible into,
systems of a lower order. These systems
are invariably overcoming the effects of
limiting factors. The limiting factor is the
stimulus to which the system reacts. The
reaction places the organism in a more effi-
cient relation with its environment, but no
matter how many reactions are carried out,
there is always some limiting factor left,
and so the organism is kept constantly
busy. The end result is to approximate
more or less closely some kind of average
of all the resources at its disposal.
I think it might be possible to go even
further and get a quantitative measure of
the degree to which the process of integra-
tion has been carried, by considering the
number of factors integrated and how close
an approximation to the normal curve of
error had been obtained. Such a quantita-
tive measure would likewise be an index of
the stage of evolution that an organism had
reached.1* At the very least, the Law of
the Minimum or the principle of limiting
factors offers a sound basis from which such
intangible processes as behavior, correla-

ganism is based essentially on a decrease in the

it is not the only scientifically accurate
point of view from which to attack such
problems. Henry D. Hooxsr, JR.

THE PECK TESTIMONIAL EXHIBIT OF
MUSHROOM MODELS
It is peculiarly fitting at this time to de-
scribe rather briefly the exhibit of mushroom
models, recently installed in the State Museum
at Albany, N. Y., as a memorial to the life
and service of the late Charles Horton Peck,
state botanist of New York from 1867 to 1915,
a period of forty-eight years, all except the last
two.years having been spent in active service.
The final installation of these remarkable
mushroom models was completed only a few
days prior to his death, which occurred on July
10, 1917. The models, fifty-seven in number
and representing fifty-five species of edible
and poisonous mushrooms, are the work of Mr.
Henri Marchand, an artist and sculptor of rare
ability. The models are made of wax from
casts in the field and reproduce with perfect
fidelity to nature, the form, coloring and habi-
tat of each species.
Space need not be taken to enumerate the
entire list of species represented by the mod-
els, but the variety of form and color may be
suggested by the following species which are
represented in the collection.
Poisonous:
Amanita phalloides
Amanita muscaria
Clitocybe illudens
Russula emetica
Inocybe asterospora
Edible or Harmless:
Amanita caesarea
Tricholoma sejunctum
Tricholoma personatum
Russula cyanoxantha
Lepiota procera
Lepiota naucina

The services of Dr. Peck in the field of my-
cology are surpassed by no other American
student of fungi. His work, although not con-
fined to the fleshy fungi, is best known from
the hundreds of species which he has described
in the fleshy and woody groups of fungi (Agari-
cacee, Boletacee, Polyporacee, Hydnacee and
Clavariacez).
Without the advantages of European travel
and study and frequently working without ac-
cess to the older European literature upon
fungi, his work stands out with conspicuous
individuality. That he has apparently de-
scribed in some eases, species already described
by the older mycologists of Europe is no reflec-
tion upon his remarkable ability in the dis-
cernment of specific and generic characters of
our native species.
His work will stand for all time as the
foundation upon which later students of the
fungi may build with safety a more elaborate
morphological and systematic revision of the
fleshy and woody groups of fungi.
Those friends, admirers and fellow botanists,
who have contributed toward bringing into
existence this testimonial exhibit of mush-
room models may well feel that there is no
more suitable memorial possible. There are
few pages of modern literature dealing with
the fleshy and woody fungi that do not reflect
in some degree the individuality of Dr. Peck’s
work, and looking at these models in the State
Museum, with their exquisite variety of form
and color, one may imagine with what pleasure
and appreciation they would be viewed by him
whom they memorialize. H. D. House

SCIENTIFIC EVENTS
FARM COLONIES FOR TUBERCULOUS
SOLDIERS
Ir is stated in the British Medical Journal
that during the past year the National Asso-
ciation for the Prevention of Consumption has
urged the formation of farm or garden
colonies where discharged tuberculous soldiers,
while regaining their health, may be trained in
open-air occupations At the annual meeting
of the association on July 16, Professor Sims
Woodhead sketched his own idea of a model
farm colony. It should consist of a large
enough tract of land to allow variety in the
forms of cultivation introduced. The aim was
not only to provide the patient with suitable
and congenial work, but also to give him an
occupation which should serve him as a means
of livelihood, and a part of the farm colony,
therefore, should be laid out on a generous
allotment system. The colony should serve as
an educational center and show how much
could be done to improve the conditions of
farm workers and the hygiene of farm build-
ings. To that end every farm colony should
be a microcosm in which the maintenance of
health and the prevention of infection should
be absolutely secured. He thought also that
accommodation should be provided for ad-
vanced eases. As far as possible, the patients
should do the whole work of the colony them-
selves, and even the overseers should be tuber-
culous patients who were coming to the end
of their term. The patient should help to con-
tribute to the cost by his own labor. The state
must provide the land, and it might also con-
tribute towards preparation of the land and
erection of the general buildings. But the
special buildings, particularly the hospital
buildings, should be jointly provided by local
taxation, Treasury loan, and voluntary sub-
scription. As the patient got stronger a cer-
tain portion of his earnings should be set aside
as a bonus for him when he made a new start .
in life. In the subsequent discussion Sir R.
W. Philip suggested that there was some risk
of opening the door of the farm colony too
wide. If the colony was to be a dumping
ground for all grades of tuberculosis, its pur-
SCIENCE
205
pose would be defeated. There must be a clear
separation between early and presumably
curable cases and dying cases; for the latter,
of course, humane provision must be made, but
not that of a farm colony. The class of cases
to be taken were those which lasted a much
longer time than the sanatorium could afford
to keep them. Sir William Osler said that the
essence of success in the treatment of the con-
sumptive soldier was that he must remain a
soldier—that is, he must be under control.
Discipline was a very necessary factor in the
life of a farm colony. Sir A. Griffith-Bos-
cawen, M.P., parliamentary secretary to the
Ministry of Pensions, said that his department
had been faced with the difficulty that medical
boards had generally assumed that when a man
was discharged for tuberculosis the condition
was not attributable to military service, and
the result was that until lately the man had
been turned adrift without pension or other
provision. In France in such eases the benefit
of the doubt was given to the man. The con-
ditions of the service might at least have
brought out the disease earlier than it would
otherwise have manifested itself. The policy
now was to assume in all cases that the disease
was the result of military service unless the
contrary was clearly proved.
RESEARCH WORK OF THE RED CROSS IN
FRANCE
ANNOUNCEMENT has been made by the Red
Cross that its War Council has appropriated
$100,000 for medical research work in France.
This action follows a report from Major
Murphy, Red Cross Commissioner to Europe,
who cabled the following from Paris to the
National Headquarters at Washington:
An extraordinary opportunity presents itself
here for medical research work. We have, serving
with various American units, some of the ablest
doctors and surgeons in the United States. Many
of these men are already conducting courses of
investigation which, if carried to successful eon-
clusions, will result in the discovery of treatments
and methods of operation which will be of great
use not only in this war, but, possibly, for years
afterwards. To carry on their work they need
certain special laboratory equipment, suitable
206
buildings, and animals for experimental purposes.
At present, equipment and personnel can not be
obtained through ordinary government sources
without delay, which makes this source of supply
quite impracticable.
Cooperation with Major Murphy in his
plans is pledged by Dr. George W. Crile, of
Cleveland, who headed the first Red Cross unit
to reach France; Dr. Lambert, Dr. J. A. Blake,
Colonels Ireland and Bradley, of General
Pershing’s staff, and various American ex-
perts on the ground.
A group of specialists in infant welfare
has been sent to France by the American Red
Cross. At its head is Dr. William P. Lucas,
professor of pediatrics in the University of
California.
He reports that there is need for doctors
and nurses for work with mothers and chil-
dren, and the Infant Welfare Unit will be
prepared to give such immediate relief as it
can. With him in the unit, which was financed
by Mrs. William Lowell Putnam, of Boston,
are Dr. J. Morris Slemons, of the Yale Med-
ieal School; Dr. Julius Parker Sedgwick,
physiological chemist, professor at the Uni-
versity of Minnesota; Dr. John C. Baldwin,
specialist in diseases of children; Dr. Clain F.
Gelston, Dr. Lucas’s assistant at the Univer-
sity of California; Dr. N. O. Pearce, another
specialist, and the following experts in sociol-
ogy and child-welfare work: Mrs. J. Morris
Slemons, Mrs. William P. Lucas, Miss Eliza-
beth Ashe and Miss Rosamond Gilder, daughter
of the poet. These specialists will survey the
situation and study the work already being
done by the French, and will practice without
receiving compensation from patients. The
task before the Red Cross, which will be car-
ried on by this and succeeding units, is not
only to cooperate with French specialists, but
also to carry on a general educational cam-
paign among French mothers in the interest of
better prenatal hygiene and scientific feeding
and care of the babies. Special efforts will be
made to protect children from tubercular in-
fection, which is particularly threatening
France to-day as a result of trench warfare.

WAR DEMONSTRATION HOSPITAL OF THE
ROCKEFELLER INSTITUTE
As has been noted in Scrmence the Rocke-
feller Institute for Medical Research has re-
cently opened a War Demonstration Hospital,
on the grounds of the Institute, at Avenue A
and 64th Street, New York, the funds for this
purpose having been provided by a special ap-
propriation of the foundation.
The purposes of this hospital are to treat
patients suffering from infected wounds by
methods which have been developed in Euro-
pean army hospitals, especially the methods
developed by Dr. Alexis Carrel and Dr. H. D.
Dakin, in the Military Hospital at Compiégne,
France, and to demonstrate these methods in a
practical way to American surgeons. The
hospital will make no charge for treatment or
care.
As a contribution to assist in solving the
problem of cantonment, hospital and other tem-
porary construction, the institute has housed
the demonstration hospital in a series of porta-
ble buildings such as are used in the most
improved base hospitals on the western front.
In this way the conditions under which hos-
pital work is carried on in France are imi-
tated; at the same time there is demonstrated
a method of knock-down construction which is
used to a large extent at the front.
The War Demonstration Hospital is a
double-walled construction with a double roof.
It is thus well protected against both heat and
cold; it is heated by steam, experience having
demonstrated the desirability of steam in
laundries, kitchens and wards, where more than
300 beds are installed.
The plan of the temporary hospital at the
Rockefeller Institute was made by Mr. Charles
Butler, a New York architect, who has for a
year and a half studied French and British
hospital construction in France; he collabo-
rated with the French war department in de-
signing hospitals.
On the basis of this experiment, it is prob-
able that such hospitals could be erected and
equipped in almost any part of the country at
the rate of $700 a bed for a 500-bed installa-
tion.
August 31, 1917]
Dr. Carrel has been granted leave of ab-
sence by the French government to come to
New York to give personal supervision of the
work of the temporary hospital. He is assisted
in his work by Dr. Adrian V. S. Lambert, of
the College of Physicians and Surgeons.
The war demonstration hospital has been or-
ganized with the approval and active coopera-
tion of the war and navy departments. In ad-
mitting surgeons to follow the demonstrations
and cases that are treated, preference will be
given to members of the army and navy med-
ical corps.

DISCUSSION AND CORRESPONDENCE
THE INTERPRETATION OF THE RESULTS OF
FIELD EXPERIMENTS WITH DIFFERENT
PHOSPHATES
THE interpretation of results of field experi-
ments with different phosphates is of present
interest, especially as the conclusions reached
by several investigators are being challenged
by Dr. C. G. Hopkins, of the Illinois Agricul-
tural Experiment Station? As is well known,
Dr. Hopkins has for several years been the
ardent champion of raw rock phosphate as a
fertilizer. He has been largely dependent,
however, on data secured by others. In fact,
not until very recently had he published re-
1 Hopkins, C. G., ‘‘Phosphates and Honesty,’’
Ill. Agri. Exp. Sta., Circular 186.
Aveust 31, 1917]
sults of his own experiments in which differ-
ent phosphates were compared.
Statements? recently made by him in regard
to the conclusions drawn in Bulletin 90 of the
Tennessee Agricultural Experiment Station
even go so far as to impugn the ability of an
author who would draw the conclusion that
bone meal proved to be, in those experiments,
superior to rock phosphate. In view of the
detailed data contained in Bulletin 90, the
writer is surprised that there should be any
serious differences of opinion in the matter.
Careful consideration has convinced him that
Dr. Hopkins has laid unwarranted stress on
a single table (XIII.), which gives some av-
erages from the three longest-continued ex-
periments, and that he has failed to give due
weight to the results of the individual series.
This raises a question as to the value of such
a table, especially to the casual reader, for it
is evident that if a short number of series be
averaged a preponderance of a single series
may distort or mask the true findings. Such
a table, therefore, is open to criticism, and
evidently should be used with discretion, but
is justified as one way of presenting a sum-
mary.
Table XIII. of Bulletin 90 gives as stated,
a summary from three series of experiments
each conducted on a different type of soil.
Series 1, as is pointed out on pages 69 and 70
and again on page 87 of the bulletin, was con-
ducted on a soil which proved to be naturally
too well supplied with phosphoric acid to be
at all well adapted to the comparison desired,
so much so that rock phosphate in the last
four years of the five-year period proved un-
profitable in three of the eight experimental
conditions. Excessive growth with lodging
reduced the yields of wheat on one half the
bone-meal plots, and even acid phosphate was
used with only a narrow margin of profit.
The soils of the other two series proved, how-
ever, to be poor in phosphoric acid and hence
well suited to a comparison of phosphates.
In series 2 the evidence is unsatisfactory
because of the lack of agreement between the
results of the two rock phosphate plots, one of
2 Science, November 3, 1916, p. 652.

211
which shows a slight loss and the other a good
profit from the use of rock phosphate. If the
latter be compared with the near-by bone-meal
plots the rock phosphate shows more profit.
In series 3, which was conducted on a soil
especially poor in phosphorie acid, the ev-
idence is decidedly in favor of bone meal as
compared with rock phosphate. Under every
one of the four experimental conditions of this
series bone meal made a large increase in
yield—equal, in fact, to the best obtained from
acid phosphate and averaged 5.6 bu. of wheat
per acre more than that obtained from rock
phosphate. Even when calculated on the dol-
lar-investment basis used by Dr. Hopkins, the
average acre profit from $1.00 invested in bone
meal was $3.05 as compared with $2.79 for
rock phosphate. In this connection it should
be mentioned that a comparison between bone
meal and rock phosphate where the cowpeas
were removed for hay was omitted in Table
XIII. because only in series 3 was such a
comparison made, the results being especially
favorable to bone meal. :
Series 4, which was not included in Table
XIII., is also worthy of consideration. This
series was conducted on a greatly impover-
ished type of soil, well known to be naturally
poor in phosphoric acid. As measured by the
yields of wheat, acid phosphate proved highly
profitable, but both bone meal and rock phos-
phate were used at a loss. However, the
writer’s records and observations of these ex-
periments, during the two years of their con-
tinuance, convinced him that bone meal could
be used profitably in the reclamation of land
of this character. On the other hand, rock
phosphate appeared next to worthless. By
way of confirmation, bone meal plots 9 and 11
produced in the second year an average of
1.41 ton of cowpea hay to an acre. The near-
by rock phosphate plots 7 and 8 produced only
0.80 ton. The value of the difference between
the two yields of hay would pay for the bone
meal used and leave a good profit. The hay
data were not given in Bulletin 90, but serve
as a good illustration of the advantage in the
interpretation of results that rests with the
person conducting the experiments.
212
In drawing his conclusions with regard to
the showing made by the different phosphates,
the writer was governed chiefly by a consid-
eration of the soil conditions and results of
the individual series and, as he thinks, very
naturally placed acid phosphate first, bone
meal second, and rock phosphate third in
profitableness.
With all the individual series in view, let
us see the kind of formula Dr. Hopkins must
use in order to arrive at his conclusion with
regard to the relative standing made by bone
meal and rock phosphate. The formula and
his conclusions may be stated as follows:
Disregard series 4, omit one half the bone-
meal data of series 3, include series 1 (con-
ducted on a soil not poor in phosphate), and
with the acid of series 2 obtain averages which
show that, as used, the bone meal returned
more profit than the rock phosphate. Now,
make the unwarranted assumption that the
profit from bone meal would decrease in di-
rect proportion to the quantity used, and ob-
tain the result that a dollar invested in rock
phosphate made a profit of 39 cents more than
a dollar invested in bone meal, or, the rock
phosphate was superior to the bone meal.
Q. E. D.
In Science, March 2, 1917, page 214, Dr.
Hopkins says: “The calculated profits men-
tioned in Professor Mooers’s Science article*
are evidently based upon different valuations
than those reported in the bulletin.” The
writer finds that the calculated profits for
both acid phosphate and rock phosphate, as
given in the Science article referred to,
should be divided by 2. This, of course, does
not affect the relative standing of the two
materials. One dollar invested in acid phos-
phate shows an average profit of $2.14 per
acre where the cowpea crops were turned un-
der, and of $2.71 where removed, but one
dollar invested in rock phosphate gave an ay-
erage return of only $1.29 under either con-
dition. The writer has assumed that Dr. Hop-
kins could give a simple explanation for his
conflicting estimates, as given in SCIENCE,
November 8, 1916, p. 652, and in Scrence,
3 Science, January 5, 1917, pp. 18 and 19.
SCIENCE
[N. S. Von. XLVI. No. 1183
March 2, 1917, p. 214. In the former article
he says, “ For each dollar invested rock phos-
phate paid back $2.29,” but in the latter ar-
ticle he says, with regard to the same data,
“Easy computations show profits per $1.00
invested of . . . $1.29 from phosphate rock.”
From correspondence with dealers in rock
phosphate, the writer is informed that until
about six years ago the usual guarantee of
fineness for the rock phosphate sold to farmers
for fertilizer purposes was that 90 per cent.
would pass through a 60-mesh sieve, but that
the present guarantee is for 90 per cent. to
pass through a 100-mesh sieve. Dr. Hopkins
seems to have this in mind when he says,
“Raw rock phosphate is now procurable in
very much better mechanical condition than
when these experiments were conducted.” 4
That he was in error with regard to the rock
phosphate used in the experiments referred to
may be seen by reference to page 59 of
Bulletin 90, where the following statement is
made: “90 per cent. was found to pass
through a 100-mesh sieve.”
In conclusion, the writer will add, that on
page 60 of Bulletin 90, the content of total
phosphoric acid in the rock phosphate was
stated to be 33.9 per cent. The usual guar-
antee and expectancy for this material, as
sold to farmers for fertilizer purposes, is a
little under 30 per cent. With perfect fair-
ness the calculations for phosphate rock used
in the experiments might have been placed
on the latter basis, and an increase of 13 per
cent. can be properly allowed—as was referred
to on page 59 of the bulletin—to the estimated
cost of the applications made. This change
would appreciably increase the unfavorable
showing made by the phosphate rock.

A METHOD FOR OBTAINING AMG@BA
In common with many teachers I have found
it necessary, at the opening of college in the
fall, to provide large numbers of the indis-
pensable ameba. I venture to set down a
method which I have found successful during
4 Science, March 2, 1917, p. 214.

several years. Publication of other methods
for obtaining a large and more or less con-
tinuous supply of these animals has not been
infrequent and many are familiar with use of
Elodea (Philotria, Michx.-Britton), Cerato-
phyllum and other aquatic plants.
The ditch-moss is not readily found in many
localities. My personal experience with sev-
eral aquatic plants yielded indifferent results
and failed to give sufficient numbers until, by
chance one season, I tried the marsh plant,
Elodes campanulata (Triadenum virginicum
(1...) Raf., see Britton and Brown) and was
rewarded with large numbers of amcbz. Al-
though absence from town in some seasons
occasioned a too long interval between the
times of collection and the use of the material,
or made it impossible to provide the proper
sequence of cultures, I have seldom been dis-
appointed in finding the animals, though they
may not have come just when wanted.
The usual custom was followed in making
up the cultures. Crystallizing dishes or bat-
tery jars—the shallower dishes gave the better
results—were crowded not too densely with
the stems of the plants. The stems were
usually cut two or three times. Tap water
and water from the pond or marsh where the
plants were collected were used, separately,
but no difference in results was noted. The
dishes were covered with plates of window
glass, placed in a room of moderate temper-
ature and there allowed to remain in diffuse
light for a period of three weeks or more.
When pains were taken to collect the plants
at intervals and provide a sequence of cul-
ures the results were most gratifying.
I have used the plant from four different
localities, collecting from the water and from
banks where the plants could only have been
submerged at high water and mixing, with
success in all cases. Since the locality seems
not to be a controlling factor, and since the
cultures of tap as well as pond water yield
the animals, I assume that the Hlodes is favor-
able for the original lodgment of amebe and
their later multiplication.

CROSSING-OVER IN THE SEX CHROMOSOME
OF THE MALE FOWL
SEVERAL years ago an experiment was begun
with the object of studying ‘the inheritance
of several sex-linked characters associated in
the same individual, but the experiment had
to be laid aside until last. year. The second
generation chicks are now at hand and prove
beyond doubt that crossing-over takes place be-
tween the sex chromosomes of the male fowl.
In this preliminary report attention will be
confined to the factors themselves, without
regard to the somatic appearances of the in-
dividuals. Three dominant sex-linked char-
acters, viz., B, I, and S were employed. B
and I were introduced on one side; §, on the
other. Hence the F, males were all BI, S,;
B and I being in paternal (or maternal) sex
chromosome, S in the maternal (or paternal).
These males have been tested by mating them
back to females of the composition b Is, b is.
If there were no crossing-over, offspring of
this back cross showing the combination of
somatic characters found in the F, male,
would not occur. Actually, however, they do
occur, thus demonstrating that crossing-over
has occurred, a chromosome having the com-
position B I §S, having been formed. Other
cross-over classes have appeared, but the one
cited is the one at the present age of the
chicks, most easily recognized.
No crossing in the female is to be expected
on theoretical grounds. None was observed
in the original cross. Partly because of prac-
tical reasons and partly because no new com-
binations were available in F,, it seemed wise
to defer a test of this point until next season,
when the new combination B I §S should be
available in the mature female.

THE EQUAL PARALLAX CURVE FOR FRONTAL

Ty the article by Mr. C. C. Trowbridge on
“The importance of lateral vision in its rela-
tion to orientation”? is given an equal paral-
lax curve showing the distances that a man

and a bird must move forward to give the
same apparent displacement of objects against
the horizon. It is the purpose of the follow-
ing note to derive an analytic expression for
this curve.
Consider first the case of lateral vision. Let
A be the starting point of the bird, and let the
two objects, A: and A: in the original axis of
vision be at the distances a, and a,, respectively,
from A. Let y be the distance that the bird
moves forward, and a the angle that is sub-
tended at its eye by the distance A:A2 (See
Fig. 1.) Then
(a) tan (a+6)=", tame ="),

trigonometric formula for the tangent of the
sum of two angles, and replacing tan 8 by its
value from the second equation of (1), we get
ytanea+a _
y—-atane y
(2)
Solving this for y gives
(3) 2y tana =@—a+t N (ae = a)? = 4aja2 tan? a.
In taking up the case of frontal vision, it is
necessary, as Mr. Trowbridge states, to have
a deflection between the line connecting the
observed objects and the direction of the man’s
motion. Designating the angle of deflection
by 5, and the distance that the man moves from
A by «x (see Fig. 2), we have by the law of sines

In plotting the curve of the practical prob-
lem we assign the values s=0, y=0O for

zero will correspond two values of « from (7)
and two values of y from (8). It is easily seen
that for the practical problem the smaller of
these must be chosen in each case; that is, we
must use the negative sign before the radicals
in (8) and (7). For Mr. Trowbridge’s curve

The Physical Basis of Society. By Caru
Ketsry, Professor of Sociology in the Uni-
versity of Pennsylvania. New York. D.
Appleton & Co. 1916. Pp. xvi-+ 406.
As its name indicates, this book deals
chiefly with the physical basis of human so-
ciety. The following subjects are considered
in sequence: the earth and man, mutual aid
and the struggle for existence, the control of
nature, the evolution of man, heredity, hered-
ity and society, race differences, sex differ-
ences, the influences of society upon popula-
tion, social institutions, and the nature of
progress.
In the chapter on the earth and man, the
author introduces too much detail for an
elementary sociological work, especially on
pages 1 to 28. Moreover, the real social
significance of much of the material is not
clearly shown. It would have been much
better if the author had developed such a topic
as the size and customs of the social group as
influenced by the prevailing method of food
getting, which is conditioned by physical en-
vironment.t Pages 28 and following give a
fairly satisfactory summary of geographic in-
fluences.
In the chapter on mutual aid and the
struggle for existence, the author again loses
himself in a mass of ill-digested detail about
the chemical and bacteriological aspects of
plant life, and devotes to this subject space
out of all proportion to its sociological sig-
nificance.
The chapter on the control of nature is done
more successfully, but the chapter on the
evolution of man is very unsatisfactory. In
1See Ellen Semple’s ‘‘Influence of Geographic
Environment,’’ pp. 54 to 65.
SCIENCE
215
this latter chapter the author launches into a
discussion of the old controversy about the
evolution of man. He has reduced state-
ments and quotations from authorities to
such small compass that their real meaning
and spirit are largely lost. At present, when
students are generally open-minded in regard
to the doctrine of evolution, it is a waste of
time to revive this theological controversy in
a book that is non-historical. The real sub-
ject-matter of this chapter, if the title is any
indication of its aim, is treated in a few
scant pages at the end.
The chapter on heredity is superior to any
of the preceding and is a good treatment of
the subject. The clarity of presentation might
have been improved by better selection of
diagrams. The chart on page 236 illustrating
the inheritance of polydactylism, although
taken from such a reliable source as Guyer,
is not well selected to illustrate the inheritance
of a dominant trait. An analysis of this
chart reveals the fact that the transmission of
polydactylism as a Mendelian trait in the fam-
ily shown, is explicable only on the assump-
tion that it is a recessive—and this contra-
dicts the caption. But explanation of the
chart in terms of the sex-limited hypothesis
does, however, permit its interpretation in
terms of dominance. Yet the author has not
introduced this qualification, hence the ex-
ample is not satisfactory. The remaining
.chapters are superior to the earlier ones.
In general, the book gives all appearances
of having been too hastily written, and thus
furnishes grounds for the criticism that the
work of sociologists is superficial. This is all
the more deplorable because the general plan
and logic of arrangement of the book are ex-
cellent. F. Stuart CHapix

ORGANIZED KNOWLEDGE AND
NATIONAL WELFARE
THE future of any nation is secure if it
lives up to its possibilities. The nation
which does this is bound to be a leader
among nations and to command world-wide
respect. Its national problems will be
solved and solved intelligently and thor-
oughly. The greatness of a man is in part
born in him and in part the product of his
environment. According to eminent biolo-
gists, he is about two fifths born and three
fifths made. Similarly, a nation is great
according to its resources and according to
its development of these resources. And
the development of those resources may be
accomplished only through organized
knowledge.
I, The Function of Organized Knowl-
edge.—Consider for a moment two manu-
facturing concerns on an equal footing as
regards output, but of which one is con-
tinually making progress through improve-
ments in manufacturing processes, develop-
ing new and valuable products and in-
vestigating the fundamental principles
underlying all these processes. This firm
will in time outstrip the other in every
way; the balance, in fact, isa very delicate
one, since the results are cumulative. In
quite a similar manner, that nation will
advance to leadership in which the increase
in organized knowledge and the application
of that knowledge are greatest. For this
reason, interest in research should be as
wide as the nation and should cover the

whole gamut of problems from administra-
tion to agriculture, from medicine to manu-
facture. For it is only through the solu-
tion of individual problems that general
principles can be arrived at and the sum
total of useful organized knowledge in-
creased.
It is essential that the wide field to be
covered be kept in mind, extending over
not only physics, chemistry, engineering
and all their branches, but all the biological
and mental sciences as well. In the last
analysis an increase in knowledge in the
field of the biological sciences means more
and better food, improved racial stock and
improved public health as well as increased
material welfare in all having to do with
plants and animals. Increased knowledge
of the fundamental principles of the mental
sciences means increased efficiency in ad-
ministration, legislation, education, opera-
tion and research. I do not mean mere
book learning in psychology, but such a
command of the fundamental principles as
will assist in the solution of all practical
problems. Increased knowledge of chem-
istry means increased ability to utilize raw
materials and an improvement in general
health and living conditions. One may
almost say that the generalized problem of
chemistry is to convert the less expensive
raw materials such as cellulose, petroleum,
glucose, various minerals and oils, starch,
nitrogen of the air and the like into food,
clothing, tools for our use and means for
national defense. An application of the
fundamental principles of physics in the
way of various engineering problems leads
to a fuller utilization of resources, new
products useful to man, makes inventions
possible and effective and adds to the gen-
eral increase in operating efficiency in
every way.
The utilization of organized knowledge
in national welfare comes about both
SCIENCE
[N. 8S. Vou. XLVI. No. 1185
through knowledge itself and the incentive
to apply that knowledge. Both ability and
incentive are essential to utilization. So
far as knowledge went, we might have
made dyes and optical glass many years
ago in this country, but since they could be
bought so cheaply there was no incentive
to develop the manufacture of such articles.
These are cases of ability without incentive.
On the other hand, there has long been an
incentive for the fixation of nitrogen and
for various mechanical devices, but these
have not been forthcoming for lack of suffi-
cient knowledge.
The incentive to do our best, to live up
to our possibilities as a nation or as indi-
viduals may be classed as either psychic or
commercial. In the last analysis, the tend-
ency towards doing our best is hardly more
than a rudimentary instinct. The com-
mercial incentive is a matter of either
supplying our direct needs or supplying
some one else’s needs for a consideration.
The psychic incentives to put forth our best
efforts may be classed under the heads of
emulation, contact, contract and struggle
for existence. A great many students
enter research because their favorite pro-
fessors have made reputations in research
or because their friends and colleagues are
doing such work. Incentive by contact
covers the psychology of getting started at
the line of work you wish to become inter-
ested in. It is well known that the work
itself produces a reaction on one’s mind
which makes it much easier to continue the
work. Exactly, this form of stimulus is
experienced in writing a scientific paper,
for example. Incentive by contract to put
forth our best efforts comes from putting
ourselves under obligation to produce cer-
tain results. The substance of this lecture
has been in my mind for many years, but
it would never have been prepared but for
my having undertaken to talk on this sub-
SEPTEMBER 14, 1917}
ject. This is a typical example of polar-
ization by contract. Finally, the incentive
of stern necessity or what we consider
necessity is perhaps the most powerful of
all in both research and application. All
who have families to support and needs to
be suppled know full well the stimulus
which comes from them.
In general, in normal times it is perhaps
no exaggeration to say that neither the
average individual nor the average nation
approaches within fifty per cent. of its
possibilities. Nothing short of a war
threatening the national existence can
shake a nation out of its lethargy. Simi-
larly, the average individual can not be in-
duced to put forth his best efforts without
the strongest of incentives. It is unfortu-
nate that this is the case. However, with
sufficient attention given to the problem
by trained experts in mental science, it is
quite possible that at some future date as
high as sixty or eighty per cent. of the
possibilites may be realized without any ap-
peal to arms for the nation or any unusual
incentive for the individual.
Il. The Increase of Organized Knowl-
edge——The research by which organized
knowledge is increased will doubtless
always be carried on chiefly by three dis-
tinet types of research organizations: re-
search by the government in national
laboratories, research by the universities
in connection with the work of instruction
and research by industrial laboratories in
connection with the interests of manu-
facturing concerns. Aside from these
three main classes of laboratories there will
always be large, privately endowed re-
search organizations, dealing with neglected
fields of remote commercial interest, private
industrial laboratories supported by con-
sulting fees and cooperative testing labora-
tories also self sustaining.
National, industrial and university re-

search follow three essentially different
lines. There is considerable overlap in
field, it is true, but each is centered on a
different kind of research. The proper
function of national research is the solu-
tion of such problems as concern the na-
tion as a whole, affect the general interests
of all classes of individuals; it is the cus-
todian of standards, it develops methods of
precise measurements and investigation,
it is trouble engineer for the solution of
very difficult problems or the problems of
producing units so small as not to be able
to have their own research laboratories.
It is the proper guardian of the public
health. It solves problems connected with
contagious and vocational diseases. It
develops methods of making good roads,
increasing the fertility of the soil and
stocking ‘waters with fish. National re-
search is of all grades from that dealing
with fundamental principles up to that re-
lating merely to lessening the costs of pro-
duction...
University research must always, in the
very nature of things, be concerned chiefly
with the advancement of the various sci-
ences as such, and with the development of
the fundamental principles of each science.
The best university instruction is along ~
these lines and investigators and students
in close touch with them will naturally
have most new ideas in close connection
with fundamental principles. University
research is necessarily one of small jobs and
the best minds and is without very much
continuity. The advanced student is in-
terested in a research just long enough to
make it acceptable as a doctor’s thesis. The
instructor is too burdened with teaching to
give more than a margin of time to re-
search. But a very small part of the uni-
versity research is extended year after year
covering a wide field. This is quite as it
should be, the university looking after those
250
fields of research of little commercial value,
on the one hand, and not directly affecting
the interests of the nation as a whole, on
the other, but of fundamental and far
reaching importance to all.
Industrial research takes the middle
eround and has already become a distinct
profession. It is in close touch with prac-
tical commercial application, on the one
hand, and with fundamental principles, on
the other. Its proper field is anything be-
tween elimination of works troubles and
the investigation of fundamental principles.
The staff of the ideal industrial research
laboratory is composed of experts of wide
experience who ean serve the manufactur-
ing departments in a consulting capacity
without sacrifice of time. We may perhaps
best summarize the preceding statements by
describing the ideal research man and the
ideal research laboratory.
Some writers have spoken of the investi-
gator as a rare individual to be sifted out
from educational institutions with great
care for a particular line of work. My per-
sonal opinion is that a large percentage of
the men students are fitted for research
work if properly started along the right
line. The investigator should have a mind
at once fertile and) well trained. His mind
should be teeming with new ideas, but he
should possess unerring judgment to reject
those which are not logical or promising.
We are often asked what sort of prepara-
tion in physics would be best for men in-
tending to take up research as a life work.
It has even been proposed to give courses
in ‘‘applied physics’’ for the benefit of
those intending to take up industrial re-
search. Our invariable reply is that the
best preparation for a research man is a
thorough grounding in the fundamental
principles of his science: physics, chemistry
or whatever it may be. If he has this thor-
ough knowledge of fundamental principles
it is safe to say that In any properly organ-
SCIENCE
[N. 8. Von. XLVI. No. 1185
ized research laboratory with the proper
leadership and companions, such a student
will have many times as many useful ideas
as he can himself possibly follow up with
research. Hardly any one who has com-
pleted advanced work in a science can read,
say an abstract journal, without thinking
of many problems which he would like to
investigate. Fertility of mind is not so
much an inborn quality of the mind itself
as of the training and association which
that mind has had.
The ideal industrial research organiza-
tion may perhaps be outlined with a knowl-
edge of its development during the last fif-
teen years. I shall give, frankly, my per-
sonal views in the matter, based on an inti-
mate knowledge of four universities, three
professional research laboratories and a
visiting acquaintance, so to speak, with
quite a number of others. The ideal in-
dustrial laboratory, in my mind, consists
of two quite distinct divisions: one taking
the brunt of works troubles and testing or
making analyses of the material used. The
other wing is complementary to this and
deals with the larger fundamental problems
encountered, problems requiring skilled
specialists and considerable time for their
solution. The alternative organization with
a single research laboratory covering both
works troubles and fundamental problems
is not so successful. The plan in this case
is to have considerable research in progress
of very little interest to the company, but
engaging a staff much larger than required
to take care of ordinary works troubles. In
this case, when works troubles are many
and insistent, as they are wont to be at
times, the staff engaged upon fundamental
research forms a reserve to be called out
occasionally to deal with works troubles.
The disadvantages of this are that the fun-
damental work is subject to more or less
frequent interruption and can not be so effi- _
ciently carried on. On the other hand,
SEPTEMBER 14, 1917]
when the research is in two quite distinct
divisions, fundamental work is not subject
to interruption by works troubles.
Industrial research is preeminently
fitted to be carried on by team work. This
we have developed to a high degree in Pitts-
burgh and consider very much more effi-
cient than the alternative cell system where
each leading man has a room or suite of
rooms to himself and keeps his work to him-
self. In the ideal organization, two or
three men work together on the same large
problem or group of problems, the aim be-
ing to have a good theoretical man and a
good experimentalist working together as
much as possible or even a physicist and
chemist in some cases. The characteristic
of the team work plan, however, is the con-
ference system. The five or six men most
interested in each line of research meet for
an hour each week to discuss the problem in
its various aspects, to plan new work and
to consider various interpretations and
applications of the results obtained. The
ideal conference is not less than four and
not more than eight men and includes an
efficient stenographer. To one experienced
in such team work, the results of getting
together are surprising. A good suggestion
is no sooner made than capped by a better
and the saving in time and effort is almost
incalculable.
The conference system also aids in put-
ting useful results before the other wing of
the research division and before the patent
department. At each of our conferences
are representatives of the other wing of
the research division, charged with taking
up any results immediately applicable, and
a member of the legal department who
takes care of any ideas worth patenting.
This plan of conferences relieves the scien-
tific men from responsibility for calling the
attention of the works or of the patent de-
partment to useful patentable results.
So far as national welfare is concerned,
SCIENCE
251
in order to increase our stock of organized
knowledge, we need more teaching by pro-
fessors and instructors in closer touch with
industrial problems. So far as developing
research men goes, the ideal instructor is
probably an ex-professional research man
and, in many cases, one who has made a
reputation or a fortune by his work along
industrial lines. Another need is, of
course, more research laboratories all along
the line. The increase would naturally be
among industrial organizations and the ex-
pense borne largely by manufacturing con-
cerns, since it is they who reap the chief
direct financial benefit.
Another great need is cooperation among
the various branches of research: univer-
sity, national and industrial. There should
be a free interchange of men between such
laboratories, and each should be thor-
oughly familiar with the needs and prob-
lems of the other. One great benefit from
this war, if it lasts sufficiently long, will be
to force cooperation between different
branches of research.
Ill. The Application of Organized
Knowledge-—tThe present national crisis
brings home to us the crying needs of the
nation in availing itself of the knowledge
and ability at its command. Fifty thou-
sand specialists in applying scientific
knowledge to practical problems as well as
seores of research laboratories have offered
their services to the nation. But problems
requiring investigation are slow in being
developed. Once they are formulated and
given to the engineers of the country, few
will remain unsolved very long.
It is for the engineer to apply the results
of research to practical problems and to
carry practical problems demanding gen-
eral research back to the research labora-
tories. To the engineer, every special prob-
lem requires a special application of funda-
mental principles. Is it too much to hope
that the day is rapidly approaching when
252
all great problems, particularly those of
our national and state governments, will
be automatically placed in the hands of
trained specialists? Not self-seeking polli-
ticians, nor yet men with mere theories, but
engineers with a real command of funda-
mental principles, men with an unbroken
record of big achievements and no failures,
men ever ready to stake their all on their
ability to handle problems in their spe-
cialty.
Professor Joseph Le Conte, in an ad-
dress years ago, remarked that each of the
great professions first attained high stand-
ing when it was taught as such in universi-
ties. When so taught, the professional
men turned out are no longer quacks, but
each has a real command of the funda-
mental principles in his chosen field of
action. The ‘basic relation is that any pro-
fession has standing in so far as its funda-
mental principles have been developed and
applied. To retain standing, a profession
must be continually increasing its stock of
knowledge of fundamental principles
through research. The engineer of stand-
ing in his profession must not be content
with a mere working knowledge of rules of
thumb, but must have a real command of
basic principles in his chosen field and in
related fields. The illuminating engineer,
for example, should know not only lighting,
but should possess a working knowledge of
the laws of vision and of geometrical and
physical optics. So the great physician or
construction engineer has a command of
his own field and an intimate acquaintance
with related fields.
So also with research as a profession, the
leaders have not only a taste for research
and logical minds to clearly analyze and
attack problems with thorough scientific
knowledge, but have a knowledge of the
principles of research; getting the most out
of their own minds, avoiding side issues,
SCIENCE
[N. S. Vou. XLVI. No. 1185
cooperating with their colleageus and put-
ting their most valuable results in perma-
nent, readily available form. Research is
one of the youngest of the professions and
one with a promising future, but let no
one enter it without thorough knowledge
or a full understanding of its aims and
methods. With sufficient attention given
to research and to its application, this na-
tion with its great national resources
should at once attain and retain a perma-
nent lead among the nations of the earth.

THE PROOF OF MICROBIAL AGENCY
IN THE CHEMICAL TRANSFORMA-
TIONS OF SOIL
Every now and then in the development of
a science it is well to stop and consider how
many of the current statements are based on
established fact and how many have arisen from
assumptions repeated so often that they have
come to be generally believed. Certain com-
mon statements in regard to the bacteriology
of soil may well bear such scrutiny. Has it,
for instance, been definitely proved that any
particular microorganisms cause any of the
well-known biological activities in soil? This
question is quite pertinent at present because
of statements frequently found in the liter-
ature that certain bacteria or groups of bac-
teria are responsible for certain chemical
transformations in soil, although complete
proof of the causal relation has never been
obtained.
The cause of these loose statements is easy
to understand when it is considered that it is
practically impossible to obtain direct evi-
dence as to what actually goes on within the
soil. Laboratory experiments show what the
microorganisms do under laboratory condi-
tions, but not what they do in the soil. Even
though the activity of an organism be tested
in soil itself, its true activity in the field may
still remain unknown, because such laboratory
tests have to be carried out in pure culture,
and pure cultures do not occur in the field.
The activities of bacteria in soil are associ-
SEPTEMBER 14, 1917]
ative actions; and an organism capable of vig-
orous activity in pure culture may be almost
inactive in the presence of its natural rivals.
Laboratory tests, therefore, give but indirect
evidence at their best. Indirect evidence has
its value; but it is futile to draw conclusions
from it unless results obtained by one method
are confirmed by those obtained in some other
way.
Similar difficulties in regard to pathogenic
bacteria caused the literature of the early nine-
teenth century to abound in misstatements as
to the relation of certain bacteria to certain
diseases. Gradually, however, it came to be
recognized that neither the constant presence
of a given microorganism in a certain disease,
nor its ability to produce a similar disease in
lower animals proves it to be the causal agent
of a human disease. These ideas were put in
concise form by Koch when he restated and
emphasized the requirements originally sug-
gested by Henle as necessary steps in proving
a given organism to be the cause of a given
disease. These postulates, as stated by Koch,
are as follows: (1) The organism must be
shown to be present in abundance in the tis-
sues, blood, or discharges of animals suffering
from the disease; (2) it must be isolated and
studied in pure culture; (3) it must be shown
capable of producing the same disease in
healthy animals; (4) it must subsequently be
found again in abundance in the experiment-
ally inoculated animals.
Really the case of bacterial activities in
soil is analogous. The constant presence of
a certain organism in manured soil, for in-
stance, does not prove that it decomposes the
manure any more than the constant presence
of an organism in a given disease proves its
causal relation. Neither does the fact that
an organism ammonifies laboratory media prove
that it ammonifies organic matter in soil, any
more than the fact that an organism produces
a certain disease in a lower animal proves that
it produces a similar disease in man. Al-
though this fact may be recognized in a gen-
eral way by soil bacteriologists, a little
thought will show that no rules as strict as
Koch’s postulates have ever been followed in
SCIENCE
253
establishing the agency of bacteria in any soil
activity—with the exception of the bacteria of
legume nodules. Even in regard to the nitri-
fiers—certain as we may be of their agency in
converting ammonium salts into nitrates—we
do not have the complete proof. This thought
is somewhat disconcerting and shows the need
of drawing up strict rules to apply to the
activities of soil microorganisms. Koch’s pos-
tulates can not be applied directly to soil
microorganisms, because the latter operate
under quite different conditions from patho-
genic bacteria; but it is possible to modify
his rules to fit soil conditions.
The first postulate is that the organism must
be shown to be present in abundance in an-
imals suffering from the disease in question.
It is equally necessary to show that an organ-
ism is present in abundance in soil in which a
certain biological activity is going on—in
fact that it is more abundant in such soil
than in similar soil in which the activity is
not taking place—before asserting that the or-
ganism in question is the causal agent. It is
also necessary to show that the organism is
present in such soil in active form. This
is necessary because at least three groups of
soil microorganisms have inactive as well as
active forms: namely, protozoa, molds and
spore-bearing bacteria. If the organism in
question belongs to one of these three groups,
the mere demonstration of its presence is not
enough, but it must be shown to be present in
active form. In other words, Koch’s first pos-
tulate must be expanded as follows when ap-
plied to soil conditions: The organism in ques-
tion must be shown to be present in active
form when the chemical transformation under
investigation is taking place; and must also be
shown to be present in larger numbers in such
soil than in similar soil in which the chemical
change is not taking place. These two steps
have seldom been carried out in investigating
the: cause of any biological activity in soil,
but they are. nevertheless as important as
Koch’s first postulate in regard to pathogenic
bacteria. They are perhaps a little more
stringent than the first postulate of Koch’s;
but special stringency is necessary here in view
254
of the difficulty in applying Koch’s last two
postulates to soil conditions.
The second postulate of Koch’s is that the
organism be isolated and cultivated in pure
culture. This can be applied without modi-
fication to soil conditions, and indeed is gen-
erally carried out by soil investigators.
The third postulate is that the organism be
shown capable of producing the same disease
in healthy animals. The corresponding re-
quirement in regard to soil bacteria is ex-
tremely difficult to meet. It is possible to in-
oculate the organism in question into sterile
soil and study its activity under such condi-
tions—a test which is quite commonly made.
Such a test, however, does not furnish con-
clusive proof. Sterilized soil is always differ-
ent from natural soil; but worse still, activi-
ties in pure culture may be very different
from activities in mixed culture. To obtain
eomplete proof, the organism in question
should be inoculated into unsterilized soil, and
then if the activity under investigation occurs
the organism should be shown to be present
in large numbers. Such a procedure, how-
ever, is generally impossible, because of the
difficulty of getting an organism to grow vig-
orously in soil already stocked with a bacter-
jal flora of its own; and the interpretation of
results is difficult, because—in distinct con-
trast to the specific agency of microorganisms
in disease—the same chemical transformation
in soil may be caused by distinctly different
organisms. For this reason the best that can
ordinarily be done is to inoculate the organ-
ism in question into sterilized soil. To do so
furnishes better proof than to inoculate it
into any laboratory medium, but the unsatis-
factory nature of the test must be fully recog-
nized. Perhaps it is not overstating the case
to say that much of the past confusion in re-
gard to the activities of soil bacteria has
arisen from the fact that they have been
studied in pure culture while pure cultures
never occur naturally in soil. The inocula-
tion of sterilized soil is ordinarily the only
practical course, however, and has its value
as a means of confirming the tests carried
out in connection with the requirements al-
ready mentioned.
_ SCIENCE
[N. 8. Vou. XLVI. No. 1185
Koch’s last postulate is that the organism
be found in the tissues, blood or discharges
of the experimentally inoculated animals.
The corresponding requirement in regard to
soil activities is superfluous, provided sterile
soil is used for inoculation and contamination
is prevented during the experiment. If un-
sterilized soil is used, the presence of the or-
ganism in question should be demonstrated ;
but the impractibility of using unsterilized
soil makes this last requirement of little value
as applied to soil conditions.
Summing up, it may be said that to show
conclusively the agency of any microorganism
in any chemical transformation occurring in
soil, the following steps are necessary: (1) The
organism must be shown to be present in ac-
tive form when the chemical transformation
under investigation is taking place; (2) it
must be shown to occur in larger numbers
under such conditions than in the same soil
in which the chemical change is not occur-
ring; (3) it must be isolated from the soil
and studied in pure culture; (4) the same
chemical change must be produced by the or-
ganism in experimentally imoculated soil,
making the test, if possible, in unsterilized
soil. The fourth reqiurement, however, can
ordinarily be carried out only by inoculating
sterilized soil, a procedure which does not
give rigid proof, but which is fairly conclusive
if carried out in connection with the other
three requirements.
Sometimes these facts can be brought out
wholly by cultural methods, such as used in
the past. It must be remembered, however,
that cultural methods, at their best, are open
to serious error, as organisms that are nat-
urally inactive may become active under cul-
tural conditions, while under similar condi-
tions naturally active organisms may lose their
activity. This fact will make it necessary to
check up cultural methods with methods of
other sorts. Possibly the use of the micro-
scope! will help solve some of the problems,

or perhaps methods of an entirely new sort
will be needed. At all events, more attention
must be given to the steps involved in proving
the causal relation of definite microorganisms
to definite biological activities in the soil in
order to avoid making loose statements in re-
gard to the functions of these organisms, such
as have often been made in the past.

THE FIRST PUEBLO RUIN IN COLO-
RADO MENTIONED IN SPANISH
DOCUMENTS
THERE is in the Congressional Library,
among the documents collected by Peter Force,
a manuscript diary of early exploration in
New Mexico, Colorado, and Utah, dated 1776,
written by two Catholic priests, Father Sil-
vester Velez Escalante and Father Francisco
Atanacio Dominguez. This diary is valuable
to students of archeology, as it contains the
first reference to a prehistoric ruin in the con-
fines of the present state of Colorado, although
the mention is too brief for positive identifi-
cation of the ruin.2?. While the context indi-
cates its approximate site, there are at this
place at least two large ruins, either of which
might be that referred to. I have no doubt
which one of these two ruins was indicated
by these early explorers, but my interest
in this ruin is both archeological and histor-
ical. Our knowledge of the structure of these
ruins is at the present day almost as imperfect
as it was a century and a half ago.
The route followed by the writers of the
diary was possibly an Indian pathway, and is
now called the old Spanish Trail. After enter-
ing Colorado it ran from near the present
site of Mancos to the Dolores. On the four-

ing entry: “En la vanda austral del Vio [Rio]

cion pequefia, de la misma forma q° las de los
Indios el Nuevo Mexico, segun manifieran las
Ruinas q° de invento registramos.”
By tracing the trip day by day, up to that
time, it appears that the ruin referred to by
these early fathers was situated somewhere
near the bend of the Dolores River, or not far
from the present town of Dolores, Colorado.
The above quotation indicates that the ruin
was a small settlement, and situated on a hill,
on the south side of the river or trail, but it
did not differ greatly from the ruined settle-
ments of the Indians of New Mexico with
which the writers were familiar, and had
already described.
A century later, 1876, we find a published
reference to a ruin near the bend of the Do-
lores, which suggests the above mentioned.
An exploring expedition of the engineer de-
partment of the United States Army from
Santa Fé, New Mexico, to the junction of the
Grand and Green Rivers of the Great Colo-
rado of the west, under command of Capt.
J. M. Macomb, U. S. A., in 1859, followed the
old Spanish Trail. Professor J. S. Newberry,
of the expedition, in a geological report de-
scribed a ruin not many miles from the bend
of the Dolores: “ Surouaro is the name of a
ruined town which must have contained a pop-
ulation of several thousands [sic]. The same
is said to be of Indian (Utah) origin, and to
signify desolation, and certainly no better
could have been selected. . . . The houses are,
many of them, large, and all built of stone,
hammer-dressed on the exposed faces. Frag-
ments of pottery are exceedingly common,
though, like the buildings, showing great age.
The remains of metates (corn mills) are
abundant about the ruins. The ruins of sey-
eral large reservoirs* built of masonry may be
seen at Surouaro, and there are traces of
acequias which led to them through which
water was brought perhaps from a great
distance.”

out excavations. J. W. F.

On several maps, as that accompanying a
report of another survey across the continent,
by William J. Palmer, published in 1867 and
1868, sites of ruins are indicated in south-
western Colorado. Printed references to Su-
rouaro are made by Jackson, Holmes, Prudden,
and other writers, but aside from the statement
of the last mentioned, that it is a cluster of
mounds indicating pueblos of the unit type,
we know little regarding their size and archi-
tectural peculiarities. The arrangement of
mounds in a cluster, like many others in the
cedar clearings, suggests the Mummy Lake
group on the Mesa Verde, and it is probable
that each member of the group if excavated
will be found to resemble Far View House.
My attention was called to a ruin near Do-
lores by Mr. R. W. Williamson, of that city,
and not being able to visit the site I urged
him and others to collect more details, from
which my belief was confirmed that the ruin
mentioned by the Spanish fathers is the same
as Newberry’s Surouaro.
As one fruit of my inquiries for corrobo-
ratory evidences bearing on the identification
of the oldest mentioned ruin, I obtained unex-
pected information from Mr. J. W. Emerson,
a ranger on the Montezuma Forest Reserve,
who is well acquainted with the region near
Dolores. In a letter received a short time ago
from Mr. Gordon Parker, supervisor of the re-
serve, who has always shown great interest in
my work at the Mesa Verde, there was en-
closed a copy of a report made by Mr. Emerson
to the Forest Service, on a remarkable ruin
near Dolores which, although not corroborat-
ing the above identification, greatly intensified
the desire of several years to visit the area in
which lies the supposed first ruin in Colorado
mentioned in writings by white men. Mr.
Emerson’s report is accompanied by a rude
ground plan, indicating a ruin as unusual in
form as the mysterious Sun Temple of the
Mesa Verde Park, which it somewhat re-
sembles.
It does not answer the description of Surou-
aro by Newberry, and its exceptional character
would not have impressed the Spanish fathers,
if they noticed it at all. In fact, judging from
SCIENCE
[N. S. Vout. XLVI. No. 1185
the “ground plan” furnished by Mr. Emer-
son, its form is remarkable even in a region
where many different forms exist.
I will not occupy the reader’s time with the
details of the building revealed in this report,
as they would be more appropriate in a formal
article and can be greatly augmented by ex-
cayations, but will point out that its form is
roughly semicircular, the plan showing con-
centric walls bounding rooms separated by
partitions, the outer straight wall on the
south side being like the south wall of Sun
Temple. The building measures 100 by 80
feet, exhibiting masonry characteristic of the
purest pueblo type. A complete excavation
promises to reveal data on the connection be-
tween the prehistoric towers of the southwest,
circular ruins, and the problematical Sun
Temple.
It is evident that the southwestern corner of
Colorado, from which locality not a single
ruin had been recorded a century and a half
ago, contains some of the largest, best con-
structed, and most mysterious pueblo ruins
and cliff dwellings in the United States, and
offers unusual data bearing on the history of
aboriginal American culture.

PRODUCTION OF NITRATES BY THE
GOVERNMENT
ANNOUNCEMENT is made by the War Depart-
ment of its preparations for the production of
nitrates in accordance with a report filed by the
Nitrate Supply Committee. This report is
given in part below. It is further stated that
for the present the location of the proposed ni-
trate plant is withheld, but information con-
cerning its location will be given as soon as a
definite decision is reached. The work of sup-
plying the machinery and materials needed
for the plant has begun.
The Nitrate Supply Committee, appointed
by the Secretary of War, was under authority
of a provision in the national defense act for
an investigation “to determine the best,

cheapest and most available means for the pro-
duction of nitrates and other products for
munitions of war and useful in the manufac-
ture of fertilizers and other products.”
The general recommendations and report of
the Nitrate Supply Committee are announced
as follows:
After a deliberate and careful consideration
of all the matter and information at the dis-
posal of the committee, it submits the follow-
ing as its action:
1. The committee, appreciating the offer of
the General Chemical Company, recommends
that the government enter into negotiations
to acquire the rights to use the synthetic am-
monia process of that company.
2. That contingent upon satisfactory ar-
rangements with the General Chemical Com-
pany, out of the $20,000,000 nitrate supply ap-
propriation such sum as may be needed, now
estimated at $3,000,000, be placed at the dis-
posal of the War Department to be used in
building a synthetic ammonia plant, employ-
ing the said process of the General Chemical
Company, and of a capacity of 60,000 pounds
of ammonia per twenty-four-hour day, said
plant to be located in a region where land,
water, coal and sulphuric acid are cheaply
available, where good transportation facilities
exist, and where the proposed new powder plant
of the government can be properly located. In
the opinion of this committee all of these con-
ditions just enumerated are best fulfilled by a
location in southwest Virginia or contiguous
region.
3. That out of the $20,000,000 nitrate sup-
ply appropriation an amount now estimated at
$600,000, or as much as may be needed, be
placed at the disposal of the War Department
to be used in building a plant for the oxidation
of ammonia to nitrie acid and the concentra-
tion of nitric acid, of a capacity equivalent to
24,000 pounds of 100 per cent. nitric acid in a
twenty-four-hour day, said plant to be located
in the neighborhood of the aforesaid synthetic
ammonia plant and the proposed new powder
plant of the government.
4. That the War Department proceed at the
earliest practical date with the construction of
SCIENCE
257
the oxidation plant and contingent upon a sat-
isfactory arrangement with the General Chem-
ical Company, also with the synthetic am-
monia plant, and that the government give
such priority orders as will secure from con-
tractors prompt delivery of the materials and
rapid construction of the structure and ma-
chinery needed for those plants.
5. The committee, appreciating the offer of
the Nitrogen Products Company granting, in
this country, to the government, under certain
conditions, the right to use the so-called
Bucher process for the production of sodium
cyanide and ammonia, recommends that a
form of contract, drawn with the advice of
the legal authorities of the government, such
as to give that company no guaranty or ex-
clusive rights in the process, or in its future
development, beyond those which the com-
pany’s own patents give to it, be entered into
with the Nitrogen Products Company, and
that experimentation looking toward the in-
dustrial development of the Bucher process for
the production of ammonia be at once pro-
ceeded with. And, further, that contingent
upon a satisfactory arrangement with the
Nitrogen Products Company, a sum not to
exceed $200,000 be allotted for this purpose
out of the $20,000,000 nitrate supply appro-
priation.
6. That out of the $20,000,000 nitrate
supply appropriation $100,000 be made avail-
able for the active prosecution of investiga-
tions of processes for the industrial produc-
tion of nitrogen compounds useful in the
manufacture of explosives or of fertilizers, and
that these investigations be planned and super-
vised by the War Department.
7. That in order to increase the production
of ammonia and toluol the government pro-
mote the installation of by-product coke ovens
by directing that priority be given in the pro-
duction, delivery, and transportation of the
materials and parts needed in their construc-
tion.
8. That the decision as to more extensive
installation of nitrogen fixation processes and
water power development in connection with
them be postponed until the plants above rec-
258
ommended are in operation or until further
need arises.
9. While the preceding recommendations in-
clude all the measures that can now judiciously
be taken for the fixation of nitrogen and the
oxidation of ammonia, it is the opinion of
the committee that the immediate accumula-
tion and the permanent maintenance of an
ample reserve, not less than 500,000 tons of
Chile saltpeter, is the measure most urgently
necessary.

DISCUSSION AND CORRESPONDENCE
TESTS OF RADIATOR HUMIDIFIERS
By request of physicians I have tested four
types of radiator humidifiers on the market
in Minneapolis. The experiments were per-
formed at my house, which is heated by hot
water. For the first three types mentioned
the tests were made at the same time on the
same radiator. The results are therefore
strictly comparable. The results for the
“Flobun” were obtained at a later date. All
results have been calculated to indicate evap-
oration, per twenty-four hours, for each hori-
zontal foot of radiator occupied by the appa-
ratus.

immediately below the cord we should have
L£=0 and therefore dw,/dt<0. But this
would increase the angle 9 and so throw the
center of gravity out from underneath IJ. The
weight of the system and the tension in IJ
would then supply a positive torque LD. It is
possible to have this torque of such magnitude
as to make dw,/dt = 0, in which case the torque
is entirely non-momental. The reason for the
necessity of this non-momental torque is easily
seen by considering an element of the rod near
G or H. When the rod is rotating there must
act upon this element a centripetal force di-
rected toward the axis JJ. This force is sup-
plied by means of the torque L.
A rotation of sufficient magnitude to make 6
very evidently greater than it is when the sys-
tem is at rest is easily imparted by hand.

A UNIQUE HORNET’S NEST
In the magazine, The Guide to Nature, Vol.
10, No. 1, June, 1917, Earl A. Newhall, of
Shelburne, Mass., under the title “ The nest of
an unknown hornet,” mentions a hornet’s nest
of peculiar form which he found hanging un-
der the eaves of an old shop. An excellent
photograph of this strange nest accompanies
the article. Newhall wrote to Dr. L. O.
Howard, of the Bureau of Entomology, send-
ing a photograph of the nest. Dr. Howard
states :
I never saw a hornet’s nest like the one in the
photograph and I have referred your letter to Mr.
S. A. Rohwer, of this bureau, who has studied these
creatures for many years and he replies as fol-
lows: ‘‘I have never seen a nest like this before
and do not know if it is an abnormal one or not.
If possible, I should like to have some of the ma-
314
kers so that it would be possible to determine the
species and thus know if it is abnormal habit.
The nest in question consisted of a globular
portion which was abruptly contracted below
into a long, slender, vertical neck of practically
uniform diameter. This slender neck served
as the only means of entrance into the struc-
ture.
The writer wishes to state that he once
found one of these unique nests at Oxford,
Mass., many years ago. This nest was kept
as a curiosity in the writer’s collections for
many years and did not fail to excite the
wonder and admiration of those who saw it.
In size and shape this nest was similar to the
one found by Newhall at Shelburne, Mass.
Newhall states that he found his specimen
under the eaves of a building. As well as the
writer can remember, the nest which he found
at Oxford, Mass., was suspended from a small
branch of a tree not far from the ground. The
maker of the nest was never seen. Although
the writer has always kept a sharp eye open
since for other specimens of this kind, none
has ever been seen. It would be of consider-
able interest to know whether the two unique
nests in question really represent abnormal
deviations of habit for some well-known spe-
cies, or the normal habit of nest-construction
for a very rare and little known, or even un-
known, species. H. A. Auuarp

SYNCHRONISM IN THE FLASHING OF
FIREFLIES
TuE articles on the flashing of fireflies which
have appeared from time to time in SCIENCE
have aroused my desire to experiment upon
the subject. The presence of two individuals
of the firefly, Photuris pennsylvanica DeG.,
in my tent at the University of Michigan
Biological Station at Douglas Lake, Mich., on
the evening of July 17, 1917, gave me my first
opportunity. With the tent dark, I watched
the two fireflies for about ten minutes. For a
while they flashed alternately, but it soon be-
came apparent that one was flashing a trifle
more frequently than the other. Consequently,
once in every two and one half to three min-
utes flashing was simultaneous. Then for
SCIENCE
[N. S. Vou. XLVI. No. 1187
about twenty minutes I experimented with a
three-celled vest pocket flashlight with the fol-
lowing results. I could easily get in rhythm
with the firefly, but I could not make the fire-
fly change its rhythm and keep with me. Some-
times the fireflies would stop while I was flash-
ing the light and again they would continue
to flash after I stopped flashing. At no time
could I control their flashings. The flashlight
and the two fireflies flashed simultaneously
when I synchronized with one of the fireflies
until its time interval brought it into coin-
cidence with the other.
On the evenings of July 19 and 25, 1917,
I had opportunity to carry the experimenta-
tion further—on each occasion with a single
firefly. The same kind of results were ob-
tained from these experiments. However, I
discovered that when I brought the flashlight
within 25 centimeters of the firefly it ceased
flashing and did not recommence until after
I had ceased flashing or until I had moved
the flashlight back a meter or more.
On many evenings at the College of Agri-
culture of the University of the Philippines,
_ at Los Bajios, I have watched splendid fire-
flies, of which there are large numbers in the
immediate vicinity. I frequently noticed that
small trees and shrubs would be more aglow
at certain times than at others, but I never
happened to observe a time when a small tree
or shrub was all alight one instant and dark
the next. In my experience there were al-
ways some fireflies flashing in the “dark”
periods. The times of greatest light occurred
when the greatest number of varying flashes
coincided.
From these observations and experiments
it seems to me that complete synchronism in
the flashing of a group of fireflies is simply
a very rare accident, occurring when the
flashes of the individuals chance to come at
the same time. Frank C. Gates

UREDINIA OF CRONARTIUM RIBICOLA ON
RIBES STEMS
Durinc the past season uredinia of Cronar-
tium ribicola Fischer have been discovered for
SEPTEMBER 28, 1917]
the first time on Ribes stems. Three natural
stem infections were observed on a plant of
Ribes hirtellum Michx. (Grossularia hirtella
(Michx.) Spach) growing in a pine woodlot at
Kittery Point, Maine. In this same woodlot
two other isolated plants of the same species,
inoculated with wciospores by applying the
moistened sciospores to the unwounded green
stems, developed respectively one and seven-
teen stem infections. Of the seventeen infec-
tions some were very evidently natural in-
fections since they occurred at points on the
stems where no exciospores had been applied.
Uredinia were produced on some of the stem
infections from the middle of June until Au-
gust 20. The urediniospores which were
formed in these sori were apparently normal in
every way. In the case of the other stem in-
fections, where no uredinia appeared, study of
sectioned material showed an abundance of
mycelium and numerous well-formed internal
uredinia in the cortex.
The discovery of sporulating uredinia on
Ribes stems complicates the already difficult
problem of detecting the disease on Ribes. In
view of the observations recorded above, it
must be concluded that no Ribes from infected
regions can be declared absolutely free from
the rust even when completely defoliated.
Moreover, the presence of the mycelium and
internal uredinia in the stem tissue is strong
evidence that the disease does in some cases
winter over on Ribes.

Drs. Ricuarp J. A. Berry and A. W. D.
Rosertson. Transactions of the Royal So-
ciety of Victoria, Vol. VI., 1914.
The volume at hand contains 270 “ life-size ”
tracings of crania of Australian natives. The
number of skulls dealt with is ninety, each
SCIENCE
315
one being represented uniformly from the
front, side and top. The publication follows
one of a similar nature in which tracings were
given of 52 Tasmanian skulls, by the same
authors, and reviewed by the writer in SclENCE
of December 16, 1910.
As to derivations, the skulls utilized with
six exceptions are all from the southeast part
of Australia, 2. e., from the region south of
the Murray River; the six exceptions are from
Queensland.
‘The authors accompany the publication with
the statement:
We are solely desirous of making available to
our scientific colleagues elsewhere, material of a
valuable character, and which is otherwise inacces-
sible, and which runs the further risk of being lost
in the process of time unless so collected. We do
not desire to impose our own deductions derived
from a study of this material upon those who may
hold different opinions from ourselves, and hence
we do not incorporate here, nor did we do so with
the Tasmanian tracings, the result of our own ob-
servations on highly debatable questions, with the
material itself. The conclusions which we our-
selves drew from the Tasmanian material have
been published in the Proceedings of the Royal
Society of Edinburgh, Volume 31, 1910, and simi-
larly the conclusions which it is our intention to
deduce from the present material will be made
available elsewhere, and in due course. Thus those
who desire to make use of the present material for
other purposes will have a free hand both now and
for the future.
As in the ease of the tracings of the Tas-
manian crania, anthropologists are thankful
to Drs. Berry and Robertson for their pains-
taking work; but as the Tasmanian volume so
the one at hand presents certain serious defi-
ciencies which are badly felt and which can
scarcely be compensated for by any subsequent
publication on the series.
In the first place there is no identification
and subdivision of the specimens according to
sex. They are evidently all of adults, yet
even this is not certain. But the most serious
deficiency is the omission of all measurements.
An illustration without at least two or three
of the principal measurements does not convey,
a full measure of confidence. It is probable
316
that the dimensions of the illustrations are
perfectly true, but had a few measurements
been given with each illustration this prob-
ability might have become a certainty.
The work incites, but does not satisfy ; which
should not be taken as criticism, but rather as
a stimulus for the future. We need more than
tracings. We need, in a most precise form,
every possible detail concerning the cranium
as well as the rest of the skeletal and physical
make-up of the Australian; and may Drs.
Berry and Robertson be soon in a position to
give us this information.

The Culture and Diseases of the Sweet Pea.
By J. J. Taupennaus. New York, E. P.
Dutton & Co. Pp. xx + 282.
In the preface the announcement is made
that this book is primarily intended to be a
practical treatise for use by both growers of
sweet peas and investigators. Those inter-
ested in the culture of this plant will no doubt
find this book a very useful and helpful guide.
It is among the few books which deal with
both the culture and diseases of one particular
crop. The author’s reason for including both
phases in the same treatise is naive in that
“the attack of most plant diseases depends
on some weak point in the cultural methods
which has weakened the host at some phase
of its life history.”
The first eighty-nine pages are devoted to
explicit cultural directions which have been
prepared for the author by specialists. The
following ninety-five pages are given to a con-
sideration of greenhouse and field troubles,
including nine diseases of fungous origin, one
of bacterial origin and a brief summary of
the several insect pests. Due space is given
in the closing chapters, in a clear, concise
manner, to methods of prevention and con-
trol of these maladies.
The essential facts in the author’s several
important investigations on the diseases of
sweet peas are summarized in this book, yet
it is believed that the investigator would pre-
fer to consult the original reports. The
grower, himself, can best judge of the author’s
SCIENCE
[N. 8. Vou. XLVI. No. 1187
success in avoiding the use of technical terms.
This same difficulty which confronts every
teacher of elementary plant pathology has
been encountered, and if one were to put him-
self in the position of the average reader he
would find himself at times in a maze of mean-
ingless terms. Certainly the person of less
than collegiate training would find himself
hopelessly lost if he attempted to wade through
certain paragraphs in this book and at such
points, one is even disposed to wonder what
verbiage the author would have chosen had
he purposed to use technical terms.
The binomial Ascochyta pisi Lib. was prob-
ably employed because it is better known than
is the name for the ascigerous stage.
The book is well and amply illustrated, is
unusually free from typographical errors and
gives the impression of being condensed yet
complete. It should have a place in the refer-
ence library of plant pathologists and of grow-
ers of sweet peas. F. A. WoLrF

FIELD CONFERENCE OF CEREAL
PATHOLOGISTS
Tue Third Annual Field Conference of
Cereal Pathologists of the American Phyto-
pathological Society was held at Madison,
Wisconsin, on July 9,10 and 11. About forty
were in attendance at the various meetings.
The following program was presented :
MONDAY, JULY 9
The forenoon was spent in visiting the plant
pathology laboratories of the University of
Wisconsin. In the afternoon, after a discus-
sion by Dr. A. G. Johnson upon “ Imperfect
Fungi causing Cereal Diseases,” the session
was continued in the field, where Dr. John-
son’s experimental plots were examined. In
the evening a supper and smoker were given
at the University Club, and in the round-table
discussion which followed, the following dis-
cussions were given:
1. Grass rusts and their réle in cereal con-
servation; Leaders, Dr. J. C. Arthur, Dr. E.
C. Stakman. Dr. Arthur gave a historical dis-
SEPTEMBER 28, 1917]
cussion of rust work, with especial reference
to his work in preparation of the rust section
of the North American flora. Dr. Stakman
pointed out five problems in the study of grass
rust: (1) Biological specialization; (2) accu-
rate knowledge of distribution of biologic
forms in relation to rust epidemics; (3) the
role of grass rusts in over-wintering uredinia ;
(4) the réle of grass rusts in passing epidemics
from the barberry to grain; (5) grasses acting
as agencies for passing epidemics from one
grain field to another.
2. The relation of the barberry to rust ept-
demics; Leaders, Dr. FE. M. Freeman, Dr. E.
M. Wilcox. In the absence of both of the
above, Dr. Stakman led the discussion upon
this topic also, Mr. Frank Piemeizel, who
has charge of the Rust Survey now in progres3
in the Mississippi Valley, stated that the sur-
vey so far had indicated that stem rust over-
winters in the extreme South in the uredinial
stage, and that the amount of infection upon
grain was found to decrease in passing from the
south to the north. South of Ames, Iowa, no
infection upon barberry was found, but north
of that point no infection was found upon
grain up to that time, except in the vicinity of
affected barberry bushes.
3. State and Federal legislation against the
barberry ; Leaders, Professor L. H. Bolley, Dr.
L. R. Jones. Professor Bolley reviewed the
methods used in securing eradiction of barberry
in North Dakota, which is the only state having
a law declaring the barberry bush a nuisance.
The work of eradicating the barberry bushes
in North Dakota has almost been completed.
Dr. Jones was unable to be present at the
session.
TUESDAY, JULY 10
The forenoon was spent in visiting the farm
near Madison operated by the Agronomy De-
partment of the University of Wisconsin. In
the afternoon the party went by auto from
Madison, Wisconsin, to Watertown, Wiscon-
sin, inspecting various grain fields on the
way. In the evening a supper, smoker and
round-table was held at the Commercial Hotel
at Watertown. The following discussions
were given:
SCIENCE
317
1. State and Federal cooperation in fighting
cereal diseases during our food emergency;
Leaders, Dr. H. B. Humphrey, Dr. F. L.
Stevens, Dr. 8S. G. Kern. Dr. Humphrey out-
lined a plan for campaign for eradication of
preventable cereal smuts. This work, depend-
ent upon the passage of the Food Bill, is to be
done in cooperation with the Extension Service,
and is to consist of two phases: first, publicity
campaign, by means of the press, posters, etc.;
second, men to be sent into the field to co-
operate with the Extension Service in secur-
ing seed treatment. The subject of com-
munity seed treatment plans was also brought
up for discussion. Dr. Kern spoke for the
need of closer cooperation between the Fed-
eral and State Departments, and between states
in their work, and of the value in correlating
work upon general problems with local ones.
Dr. Stevens was not present at the meeting.
2. Recent investigations on yellow stripe
rust; Charles W. Hungerford. An account
was given of work being carried on at Cor-
vallis, Oregon, upon this disease.
WEDNESDAY, JULY 11
The day was spent in Juneau, Wisconsin,
Beaverdam, Wisconsin, and on the farm of
Mr. Kruger near Beaverdam. Meetings were
held at the Court House in Juneau, and at
the Mealy Hotel at Beaverdam. These meet-
ings were open for general discussion and
transaction of business.
The following business was transacted at
the various meetings:
It was voted to have the secretary com-
municate with the Secretary of the Interstate
Cereal Conference to arrange, if possible, to
have the next meeting of Cereal Pathologists
held at the same place as the Cereal Con-
ference, with one day overlapping for joint
meeting.
A committee consisting of Dr. L. R. Jones,
Dr. H. B. Humphrey, drew up the following
resolution, which was unanimously adopted:
To THE HONORABLE,
THE SECRETARY OF AGRICULTURE.
We, the plant pathologists representing the
chief grain-growing states in conference
318
assembled, in recognition of the following
facts:
1. The national and international need of
the maximum production of all food grains
for the immediate future.
2. The preventable losses resulting from
smuts and other seed-borne diseases.
3. Practical and simple methods of seed
treatment known to prevent such losses.
4, The Office of Cereal Investigations has
already instigated a movement looking to the
more universal treatment of seed for the pre-
vention of these losses.
Resolve: (1) That it is our conviction that
this. work should be pushed with all possible
diligence. (2) That we as representatives of
these grain-growing states pledge to this work
our hearty cooperation and support.
A committee consisting of Professor H. L.
Bolley, Professor M. A. Carleton, and Dr. L.
R. Jones, appointed to draft resolutions for
the extermination of the barberry bushes,
made the following report, which was ac-
cepted :
In view of the vital importance of the
wheat crop, and as a national emergency meas-
ure likely to prove an effective aid in increas-
ing and insuring a better wheat crop in 1918,
be it resolved:
That we, the cereal pathologists of the
American Phytopathological Society, in sum-
mer session assembled at Madison, Wisconsin,
respectfully ask the President of the United
States to appoint a commission to consider
the relation of the barberry to outbreaks of
black stem rust of wheat, barley, other cereals
and grasses with a view of deciding upon the
desirability of eradiction of all cereal rust-
bearing strains of the barberry in the United
States in order that this source of rust epi-
demics may be removed.
Be it further resolved that the Secretary be
instructed to send a copy of this resolution
to the President of the United States.
The following resolutions were also adopted
by the Conference:
That the chairman of this body appoint a
committee to take up with federal authorities
the matter of securing some definite action
to insure an adequate supply of fungicides
and insecticides, particularly those containing
copper, for the protection of important crops
against the destruction of fungous diseases
and insect pests and to insure a reasonable
price for the same such as shall not be pro-
hibitory to their use by the farmers and fruit
growers of the United States.

SPECIAL ARTICLES
THE POSSIBLE ORIGIN OF THE TOXICITY OF
ULTRA-VIOLET LIGHT?
It is a general law of photochemical action
that only those rays are effective which are ab-
sorbed by the system in which the reaction oc-
curs.? Visible light-rays are not, as a general
tule, selectively absorbed by protoplasm and
hence their action is usually confined to spe-
cialized pigmented areas which constitute the
receptive elements of optical sense-organs.
Ultra-violet light, on the contrary, is generally
highly toxic, even for colorless organisms, and
since this toxicity presumably depends upon
and is attributable to photochemical reactions
the question presents itself to which constitu-
ent of the protoplasm are we to attribute the
selective absorption of these rays which is the
necessary precedent of their photochemical ac-
tivity ?
It was pointed out nearly forty years ago by
Soret? that the majority of proteins exhibit a
well-marked absorption-band in the ultra-vio-
let spectrum. In seeking for the origin of this
absorption-band Soret found that it is espe-
cially well exhibited by solutions of tyrosin,

and therefore referred it to the tyrosin radical
in the protein molecule. These observations
have recently been greatly extended by Kober,*
who has carried out a spectrographic examina-
tion of solutions of the various amino-acids
which are the end-results of protein hydrolysis
and of certain polypeptids. Kober has con-
firmed the existence of an absorption-band in
the ultra-violet in solutions of tyrosin and also
finds that a similar band is exhibited by solu-
tions of phenylalanin. The other amino-acid
constituents of the protein molecule exhibit
only general (7. e., non-selective) absorption in
the ultra-violet spectrum.
The possibility is thus indicated that the
tyrosin and phenylalanin radicals of the pro-
teins constitute the optical sensitizers which
render living cells susceptible to the toxic ac-
tion of ultra-violet light. If this were the case
then passage of the light through solutions of
proteins or the aromatic amino-acids should,
by absorption of the toxic rays, to a greater or
less extent deprive the light of its toxicity for
protoplasm. With this possibility in view the
following experiments were undertaken:
Definite volumes of a densely inhabited cul-
ture of paramecia were washed by suspending
the organisms in tap-water and concentrating
them by moderate centrifugalizations until a
thick suspension of uninjured organisms in a
colorless liquid was obtained. All of the sus-
pensions used were prepared in exactly the
same manner and were derived from the same
culture.
Our first step was to determine what we have
called the “normal extermination period,”
that is to say the duration of time in seconds
of exposure to the direct rays of a Cooper-Hew-
itt Ultra-violet Light Type Z at a distance of
12 cm. from the quartz tube. For this pur-
pose 0.5 ¢.c. of paramecium suspension was
placed in a flat-bottomed (Syracuse) watch-
glass and 0.5 ec.c. of tap-water was added.
Trials were made with varying times of ex-
posure and the percentage of organisms killed
was estimated by counting the individuals of
which the cilia had ceased moving. The nor-
4P. A. Kober, Journ. Biol. Chem., 22 (1915)

mal extermination-period was found, under
these conditions, to be about 100 seconds. To
determine whether the gases formed during the
exposure to the ultra-violet light (ozone and
nitric-oxide) hastened the killing of the organ-
isms appreciably, a trial was made with a sus-
pension protected from the ultra-violet rays by
a thick glass plate, but still exposed to the
gases. In this way it was determined that this
factor could be overlooked, since after 900 sec-
onds exposure no noticeable effect was ob-
served.
After determining the normal extermina-
tion-period with the above procedure, trials
were made with similar suspensions in solu-
tios of Witte-peptone, gelatin, amino-acids,
etc., the results of 160 such trials being sum-
marized in the table below. Thus a 1 per cent.
alanin suspension of paramecia was prepared
by adding 0.5 c.c. of a 2 per cent. solution of
alanin to 0.5 c.c. of washed paramecium sus-
pension.
The extermination-periods enumerated in
the tables are meant to indicate that immedi-
ately after the stated period of exposure 100
per cent. of the organisms were dead. For it
was found that even after an exposure as brief
as 40 seconds in a water-suspension the organ-
isms were affected and ultimately all died.

Glutamic acid, amino-benzoie acid and as-
partie acid all proved to be themselves toxic
for the organisms and could not therefore be
tested by this method. Tyrosin is very spar-
ingly soluble in cold neutral water. A satu-
rated solution, although exceedingly dilute,
conferred marked protection, the extermina-
tion-period being lengthened to 180 seconds.
An alkaline solution proved to be toxic and
therefore could not be employed in this way.
320
In order to rule out the possibility that the
protective action might be indirect, 2. e., not
attributable to mere absorption of the toxic
rays, and also to permit the employment of
toxie acids the following modified procedure
was employed:
In a quartz beaker with a diameter of 32
mm. 2 c.c. of the given acid were placed, this
amount being just sufficient to completely
cover the bottom of the beaker. A square
piece of cardboard was placed on the Syracuse
dish containing the paramecium suspension.
The quartz beaker was then placed over a cir-
cular opening in the cardboard, having a diam-
eter of 25 mm. By this means the organisms
were shielded from all ultra-violet rays except-
ing those which passed through the solution in
the quartz beaker. In order to fully expose all
of the organisms and to standardize the depth
of suspension, a paraffine mould was made in
the Syracuse dish by holding a No. 3 rubber
stopper in the center of the dish and pouring
melted paraffine around it. On cooling, the
stopper was withdrawn, leaving a depression
20 mm. in diameter in which 0.5 ¢e.c. of para-
Imecium suspension was placed.
Somewhat over 100 exposures were made,
using this method with the following results:

Tt will be noted that the results obtained by
this procedure confirm those previously ob-
tained by the method of immersion.
In order to obtain 1 per cent. solutions of
tyrosin and cystin, which are very sparingly
soluble in water, slight amounts of alkali were
added to the test solution in the beaker and the
extermination-periods after passage of the rays
through alkaline solutions of these acids and
of certain of the acids enumerated above were
determined, with the following results:

We may infer that solutions of gelatine, pep-
tone, amino-benzoic acid, cystin, tyrosin and
leucin detoxicate ultra-violet rays which pass
through them, while solutions of the other sub-
stances investigated do not appreciably do so.
The protective action of tyrosin in alkaline so-
lutions is exceptionally marked, and in this
connection it is of especial interest to note
that Kober has found that an alkaline reaction
markedly increases the absorption of ultra-
violet rays by tyrosin solutions.
The protective action of leucin, which does
not exhibit a selective absorption in the ultra-
violet, is at first sight somewhat puzzling. It
was noticed, however, that both tyrosin and
leucin solutions underwent a change of color
upon continued exposure to the ultra-violet
light. This change was especially marked in
the leucin solutions resulting after 40 minutes
exposure in closed quartz vessels in the pro-
duction of a dark brown fluid having a dis-
tinctly intensified odor. This solution had a
much greater protective power when tested in
the above manner than leucin solutions which
had not been previously exposed to the light.
We may infer that ultra-violet light induces
chemical changes in a leucin solution resulting
in the production of substances having an en-
hanced power of absorbing ultra-violet rays.
Our results are therefore decidedly in har-
mony with the view that the susceptibility of
protoplasm to ultra-violet light is conditioned
by the selective absorption of the toxic rays by
the aromatic amino-acid radicals of the pro-
teins.

THE OUTLOOK IN CHEMISTRY IN THE
UNITED STATES}?
Ir is the highest privilege of the presi-
dent of the American Chemical Society to
express to you, citizens of Boston, the so-
ciety’s deep appreciation of your interest
in our science and of your courtesy in pro-
viding entertainment for our numerous
membership. In token of the reality of this
appreciation, no less than in recognition of
the honor bestowed upon me by you, my
fellow members in the society, it is my
pleasant duty to address you on some sub-
ject which might interest you as an impor-
tant phase of chemistry or which might
bring home to you as thoughtful citizens of
this great country of ours some of the im-
portant functions which our science may
be expected to fulfil in the life of the na-
tion. It is the president’s happy privilege
also to select his own subject. In normal
times, I confess, I should have enjoyed the
pleasure the scientific man finds in riding
his own hobby before a large and friendly
publie and I should have been tempted to
try to present to you some phase of those
wonderfully intricate worlds of atoms and
molecules and of the forces controlling
them, on which the peculiar power of our
science rests. But the spirit of complete
preoccupation in the great test to which our
country is being put, which I know per-
vades the minds and souls of all of you, has
led me rather to the choice of a subject of
more immediate relation to our present
situation. I have thought you might be in-
terested in a discussion of the outlook in
1 President’s address delivered before the Ameri-
can Chemical Society, September 12, 1917, at Bos-

chemistry in the United States, with spe-
cial reference to the resources of chemis-
try in the nation’s service in war and in
peace, as seen from the point of view both
of chemical industry and of universities
and colleges, the sources from which our
chemists and our chemical lore are derived.
The great European war and now our
own entry into the world struggle of free
democracies against the organized military
power of the last strongholds of feudal
privilege in western civilization have
brought home to the public as never before
in the history of the world the vital place
which chemistry occupies in the life of na-
tions. What is it, indeed, that is so funda-
mental in this science that a country’s very
existence in times of great emergencies and
its prosperity at any time may depend on
its master minds in chemistry? It is the
fact, summed up in the fewest possible
words, that chemistry is the science of the
transformation of matter. Since every
phase of our existence is bound up with
matter, from our birth to our return to
dust, we find at every turn in life that
chemistry is in demand to aid man in his
effort to assure to himself a safe, scientific
control in the supplying of his own needs,
where nature, from time immemorial, has
shown the same impersonal indifference as
to his wants, his survival or destruction,
that she has for every other form of life!
From the transformation of our raw ores
into finished metals of almost any conceiy-
able quality and application, to the trans-
formation of rocks and salts and the gases
of our atmosphere into nourishing foods,
from the transformation of the yield of our
peaceful cotton fields and rich coal depos-
its into death-dealing explosives, to the
preparation of blessed life-saving medica-
ments from the same crude sources—to
mention only a few instances of the trans-
formation of matter that I have in mind—
it is chemistry that is giving us the power
SCIENCE
[N. S. Vou. XLVI. No. 1188
to satisfy our needs, whether it be for wise
and beneficent purposes or for the fulfil-
ment of our more baneful desires.
The crisis of the war has put this great
controlling science, as it has put all other
human agencies, to the fire test in every
great country on the face of the earth.
Acknowledgedly, chemistry has thus far
staved off defeat for Germany after Joffre
on the Marne had killed her hopes for a
swift, crushing victory through the viola-
tion of Belgium, and had taught her that
she must face a long struggle, in which, cut
off from the world’s supplies, she must
make shift with what her own territories
could yield and her chemists could produce.
In the wonderful organization of power in
France and in England in the midst of
war, the French and English chemists have
stepped in and brought their supplies of
munitions of every variety, of remedies, of
their new weapons of defense and offense
in poison gas and liquid fire warfare up
to the point of meeting now on more than
equal terms an enemy prepared years in
advance. And in our country too our
chemists have stood the ordeal of an un-
precedented time. I have in mind our
splendid achievement of having solved in
these three years of warfare such tremen-
dous problems which these years have
brought to us as were involved in the
speeding up of the production of thousands
and thousands of tons of fundamental
chemical products needed by our allies and
now for our own purposes—steel and iron
alloys of every variety of toughness, hard-
ness or elasticity, purified copper by the
millions of pounds, aluminium for airships
and motor ears, abrasives on which the
trueness of every great and every small gun
depends, sulphuric acid and alcohol for the
preparation of explosives—foods, oils and
scores of other essential products prepared
on a scale never seen before—I think we
may say with justifiable pride that our
OcroseEr 5, 1917]
great basic chemical industries have suc-
cessfully risen to the demands of a situa-
tion unparalleled in its scope and urgency.
There have been times of delay and times of
worry, but the few failures have been due
rather to financial difficulties than to a
breakdown in scientific efficiency. To those
of us who know that the chemist is the final
controlling mind, guiding in safety for the
financier these vast undertakings and ex-
pansions, the record of these years is truly
a wonderfully satisfactory response to the
first crucial test of the efficiency of chemis-
try in America.
And this result justifies the faith that we
will win out just as surely in the hundreds
of newer problems brought to us by our
own participation in the war. Some of
these problems have been brought to the at-
tention of our members by the chairman of
the two chief chemistry committees, which
are cooperating with the government—Dr.
W. H. Nichols, chairman of the committee
on chemistry of the National Defense
Council, an industrial committee, and by
Dr. M. T. Bogert, chairman of the chemis-
try committee of the National Research
Council, a research committee. From San
Francisco to Boston, from Minnesota to
Texas, our chemists have shown the all-
pervading desire to bring to the immediate
practical assistance of our country every
ounce of our strength and every grain of
our intelligence, and have stepped into line
for service not only with splendid enthusi-
asm, but still better, with the grim deter-
mination of purposeful men, who know well
our enemies’ strength, but who will do our
share to eliminate, effectively, unscrupu-
lous militarism from the politics of the
world! The immediate response to the
tender of the services of our membership to
the President of the United States and of
the organization of the members for such
service through a census of chemists has
been an increase in our membership from
SCIENCE
323
a total of some 8,000 to 10,500, an unprece-
dented growth, which shows unequivocally
that the chemists of the United States are
of one mind in ranging themselves on the
side of organized, whole-hearted and force-
ful support of our government in this war!
Indeed, one of our chief difficulties has
been to restrain our men in their eagerness
until proper organization would enable the
central committees to designate to each
man the field in which he could serve best.
To the impatient chemists, waiting for
their ‘‘marching orders’’ it may have ap-
peared that invaluable time has been wasted
and that progress even now is all too slow.
But work on all the most important prob-
lems really was quickly organized and al-
ready important results are available. As
an illustration of this fact we have the
brilliant and speedy success of Dr. Day and
his collaborators in producing optical glass,
so much needed for range-finders, which
will bring our shots home to the enemy.
The very nature of most of the problems
makes it impossible to name them here, but
I may say that improvements in explosives,
multiplication of the sources of supply
from which to manufacture explosives, in-
cluding the utilization of the atmospheric
nitrogen for the production of nitric acid,
providing protection for our soldiers and
sailors against poisonous gases, the ma-
king of chemicals for which we have
hitherto been dependent on importations,
these are some of the problems on which
many of our ablest chemists have been
working with all the power and concentra-
tion that the occasion demands. I may be
more explicit in regard to the problem of
the home manufacture of so-called syn-
thetic remedies, for the supplies of which
up to the present time we have turned to
our present enemies. We need large sup-
ples of salvarsan for our hospitals and
for our armies, we need local anesthetics,
substitutes for cocaine, for our surgeons,
324
we need safe hypnotics to insure blessed
sleep to sufferers in home or hospital, we
need a long list of products to relieve the
numberless ailments to which man is sub-
ject. Many of the best of these products
are protected by patents, but the Adamson
law will make it possible for American
manufacturers to prepare these remedies
in this country. There is nothing wonder-
ful about their preparation—the scientific
skill and experience of American chemists
is coping with them as easily as an expert
chess-player solves his problem in chess—
and indeed with much the same kind of en-
joyment. For instance, the obstacles in the
way of the preparation of some drugs, most
meeded but prepared with considerable
difficulty, such as salvarsan and atophan,
have already been overcome in a way that
leaves no doubt, if any ever existed, as to
our ability to stand on our own feet, once
Congress has removed the legal disabilities.
University men and industrial firms have
united in the vigorous attack on this prob-
lem.
This question brings me to another phase
of my subject. Looking beyond the im-
mediate future to the years ahead, why
should we ever again be dependent on any
foreign country for such fundamental
needs of a nation as the best remedies for
its stricken people—or, enlarging the ques-
tion—for such fundamental industrial
needs as dyes and dozens of finer chemicals,
the need of which has seriously handi-
capped manufacturers and to a certain ex-
tent is still interfering with normal activ-
ity? It has been publicly urged in Ger-
many—lI am quoting from an excellent ar-
ticle by our friend Dr. Baekeland—that
German dye manufacturers after the war
should allow only a limited and conditional
quantity of dyes to go to foreign countries,
including the United States, in order to
give her home industries a great lead in
SCIENCE
[N. 8. Vou. XLVI. No. 1188
recovering the commerce of the world in
textiles. Even if this suggestion should
not be put into effect, for Germany has
more to lose than to gain by a policy of
trade-war after the reestablishment of
peace, we may be sure that her own manu-
facturers will get the best of her supplies
and every possible advantage. Our textile
manufacturers and many other branches
of industry will be at the mercy of com-
petitors, assisted by government direction,
unless we have a declaration of chemical
independence in this country! Every
thoughtful chemist, I am convinced, and I
trust that every other thoughtful citizen,
will acquiesce in the policy that henceforth
in our basic needs, at least, we be independ-
ent of the friendship or enmity of foreign
nations! And that conclusion brings me to
one of the most important points in my
discussion this evening: What are some of
the main conditions, from a chemist’s point
of view, that must be fufilled, if we are to
look forward to successful industrial and
scientific development and independence,
when the tremendous competition of peace
must be met. These conditions are to be
sought not only in the field of applied chem-
istry—and applied chemistry includes
every great national industry, from agri-
culture to the manufacture of steel—but
they involve also our universities, technical
schools and colleges, the great sources from
which our chemists come, not only equipped
technically for their work, but carrying
also the inspiration, the orientation, which
will make or mar them and with them will
make or mar that part of the nation’s life
which will be dependent on chemistry.
Turning first to the field of applied
chemistry, I would like to emphasize that
in my opinion the most important. single
factor which would lead to a tremendous
increase in power in our industrial devel-
opment is not immediately a question of
Octoser 5, 1917]
scientific achievement, but a factor found
in a simple psychological analysis of our
industrial situation. Let our manufactur-
ers but awaken to the great significance, to
the full meaning of the simple old behest
that the laborer is worthy of his hire, and
they will be astounded at the results.
American manufacturers at present on the
whole do not treat their chemists, and es-
pecially their research and directing chem-
ists, fairly. The tendency is to exploit the
chemist as an employee, instead of treating
him as a partner, who brings scientific ex-
perience, skill and acumen to the aid of
capital and commercial experience and
standing. Manufacturers are willing to
cooperate essentially on the footing of part-
ners with great lawyers, who solve their
legal difficulties—usually a wholly sterile
performance as far as the welfare of the
mation as a whole is concerned—but they
have not yet learned to cooperate in the
same fashion with men of our profession,
who solve their technical difficulties to the
direct enhancement of the nation’s wealth
and welfare! Our chemists know and feel
that they are being exploited and in con-
scious or unconscious resentment, after one
bitter disappointment or the other in their
employers’ fairness, they lose their fresh
enthusiasm and their capacity for the
whole-hearted, unstinting effort that goes
with the work in which the heart and soul
support the mind! All this is wrong. Re-
search and managing chemists should be
sure that success means partnership in the
fruits of their success, that success will
yield immediately and not in some hazy
future of a soon-forgotten promise, an
equitable share in the actual benefits of the
work done. This is one of the real but un-
recognized sources of the unquestioned
leadership of Germany in fields chemical:
Dr. Bernthsen, director of the Badische
Anilin-Fabrik, probably the greatest of the
SCIENCE
325
many great German firms, told me some
fifteen years ago that from the lowliest
workman up to the highest chemist in his
employ, every individual is guaranteed by
contract a royalty, a definite share in the
money earned or saved by any suggestion
or discovery on the part of the individual.
Contrast this wise policy with what is com-
mon knowledge concerning the situation
in the great majority of American plants.
Any chemist can multiply indefinitely the
single specific illustration of this attitude
that I will give. One of our doctors of
philosophy of the University of Chicago, as
chief chemist for one of the very largest
manufacturing concerns in the country—
a unit in a “‘ trust ’’—perfected a device,
simple in itself, that saved the corporation
perhaps $80,000 a year: his reward was a
princely increase of $200 or $300 a year in
salary! Incidentally, let me say that I
promptly took him away from this corpor-
ation—we can not afford to waste good men
in such places. In case after case that has
come to my notice from some of our lead-
ing men, chemists have been cuddled and
patronized until their improvements have
been completed and then recognition has
come munificently in the form of a few
hundred dollars a year and—oblivion.
These men, leading men, let me remind you,
have acknowledged to me that this treat-
ment killed outright all the fire of enthusi-
asm with which they had been wont to
work! There are a few noteworthy excep-
tions among corporations, but their
strength and prosperity confirm the validity
of the appeal I am making, for they have
recognized that in large measure their con-
tinued prosperity has been the result of the
brain-work of their chemists, cooperating
with the brain-work of their directors and
the capital of their corporations. There
are also prominent exceptions among in-
dividual chemists: we have men in our So-
326
ciety who have worked their way to posi-
tions and incomes on a par with those of
successful lawyers and physicians—but
manufacturers should heed well that almost
invariably these are men who withdrew
from their original direct employment by
corporations and have developed their own
independent establishments, either as con-
sulting chemists or as independent, com-
peting manufacturers! How much wiser
it would have been for the manufacturers
—I am not saying, for the chemists—if
these brilliant, forceful men had been kept
in their establishments, as they would have
been abroad, by fair treatment as partners
im success as well as in effort.
I have dwelt long on this plea because
I consider this message to our manufactur-
ers from an outside observer, a university
man without any industrial affiliations, to
be perhaps the most important service I
can try to render our country in this privi-
leged address. Let me summarize my point
with the aid of an analogy which I owe to
my friend Dr. Hisenschiml’s remarks after
a presentation of this subject to our local
section in Chicago: Just as Napoleon let
every soldier feel that he carried a mar-
shal’s baton in his knapsack and thus se-
cured the enthusiastic and self-sacrificing
support of his hundreds of thousands, so
our manufacturers should let their chem-
ists feel that each one carries in his brains a
contract of partnership—and all that is in-
volved therein! If this is done, we will
witness through the tremendous power
of the combination of psychological mo-
mentum and trained, scientific minds, the
dawn of an era of power and prosperity in
our industries, in which no one need fear
the after-the-war competition for which all
Europe is now preparing. Enlightened
self-interest is slowly revolutionizing and
improving our whole social fabric by a
fairer, more honest conception of the rela-
SCIENCE
[N. S. Von. XLVI. No. 1188
tion of capital to workers—with harm to
no one, least of all, and to their own sur-
prise, to those who have blindly been op-
posing the movement. And my plea for
fairer treatment of productive chemists is
the point at which the great world move-
ment touches our scientifie body.
Another vitally important factor in the
outlook for chemistry in the United States
is the adoption by our legislative bodies
of a definite national policy looking toward
the establishment of that independence of
our country in the matter of chemical sup-
plies to which reference was made before.
Action in this direction has been happily
inaugurated in the fundamental matter of
the fixation of atmospheric nitrogen for the
manufacture of explosives in war times, of
fertilizers in peace and war. The fixation
of nitrogen plants in Germany have un-
questionably saved her thus far both from
a military collapse and from starvation.
As has been indicated before, it is impor-
tant too that we become independent in as
large a measure as possible also in regard
to all manufactured chemicals and particu-
larly also the finer organic chemicals, in-
cluding the dyes and the synthetic drugs.
The most important measure necessary to
this end is protection by duties such as a
non-partisan commission of experts may
find necessary. American textile manu-
facturers, who have opposed this action in
the past as far as dyes are concerned, have,
I trust, learned their lesson, and will not,
I hope, need a second more sharply pointed
one. And other manufacturers, having
found their supplies of needed chemicals
cut off or enormously increased in cost, will
also, I imagine, favor the establishment of
conditions making home production pos-
sible. It is a source of gratification to
me to state that the United States Tariff
Commission, which is making a scientific
study of the vexed tariff problem, most
OcrosEr 5, 1917]
courteously asked for, and received, the co-
operation of this society in the choice of
an unprejudiced expert on the chemical
schedules.
Wise patent legislation is another fun-
damental consideration in a declaration of
chemical independence. The public—that
is, their representatives in Washington—
should understand what is obvious to any
professional student of the problem,
namely, that independence is altogether a
question of capital, not of science—of dol-
lars, not of chemists. Our unqualified suc-
cess in every line of applied chemistry in
which investment of capital has been an
attractive proposition is positive evidence
that we have the chemists and the knowl-
edge to achieve this independence, if wise
legislation by tariff and patent laws will
insure to capital a return sufficiently at-
tractive and stable to have it enter these
needed fields.
To illustrate concretely what this policy
would mean for the nation let us consider
the following: Much more than a question
of coloring materials is concerned in a con-
scious policy to have our dye industries
established on a permanent basis. It has
often been emphasized that the manufac-
ture of dyes is so closely related to the
preparation of explosives that a flourishing
dye industry in times of peace means ample
facilities for explosives in times of war.
No American would care to contemplate
what our position would be in the matter
of large scale production of explosives if
we had become engaged in a struggle with
a first class power without the benefit of
the great expansion in our dye and ex-
plosives factories which our commerce with
England and France brought about after
1914! When peace comes, let no American
forget this lesson! One way of insuring
ourselves against a lack of facilities for
a sudden expansion in the production of ex-
SCIENCE
°
327
plosives is to keep capital invested in dye
factories.
Independence in the preparation of me-
dicinal remedies, especially also of the
finer modern products which we call syn-
thetic drugs, should be as conscious an aim
of the United States as independence in the
manufacture of dyes. It is worth noting
that the two aims support each other, for
nearly all of the basic products needed for
the large scale preparation of synthetic
remedies are either prepared in aniline dye
factories as intermediate steps toward the
dyes or are so closely related to such com-
pounds that it would be a mere detail to in-
clude these products in the normal output
of a dye factory. As an instance pointing
in this direction, recent correspondence
with a prominent American firm, which has
invented and is manufacturing what prom-
ises to be a valuable substitute for cocaine
in producing local anesthesia, brought out
the fact that the chief difficulty in the way
of the production of the drug on the large
seale which the situation demands, lies in
the securing of sufficient quantities of the
chemicals diethylaniline and cinnamic acid.
Now, the former could and should be manu-
factured in dye factories with the greatest
of ease, side by side with dimethylaniline,
which is a common intermediate in the
manufacture of many dyes, and cinnamic
acid could be prepared from benzaldehyde,
another intermediate. Furthermore, large
research departments in well-organized dye
factories will be centers of research in ap-
plied organic chemistry and practically all
of our valuable synthetic drugs are such
organic compounds. Indeed, it will be a
matter of time only—and I should like to
see that time shortened as much as possible
—when some of our best equipped and most
progressive dye factories will turn to the
problem of these remedies as a question of
the economic utilization of their equipment.
328
That has been the history abroad and it
will be the same here. In fact, together
with our long-established great pharma-
ceutical houses, they should find even
richer, unexploited fields of effort in the
problems of synthetic drugs than in those
of dyes. Without question the average
man spends on necessary drugs for his
family at least a thousandfold the value of
the dyes in the wardrobes of his whole
family—the ladies, of course, included.
The twitchings of rheumatism or gout,
sleepless nights or a cantankerous cold are
most urgent and persuasive drawers on a
family purse. My professional friends in
the audience know well how the modern
dye industry has been built up on an accu-
rate scientific knowledge of the connection
between color and what we call the strue-
ture of the molecules, those minute worlds
on the knowledge of which our power to re-
construct matter rests. We know too that
the dye industry has reached, or almost
reached, its full maturity and capacity.
But we are only on the threshold of exactly
the same kind of development in the dis-
covery of improved remedies for curing
human ills because the connection between
the structure of our molecular worlds and
their medicinal effect is just beginning to
be systematically elaborated. Great indus-
trial establishments founded on organic
chemistry, like the dye manufacturing and
the great pharmaceutical houses, collabo-
rating with research laboratories in uni-
versities and in medical institutes, would
hold out to this country the promise of a
share in realizing a duplication of the con-
quest of the world of color, which has oc-
curred in the last fifty years, by the greater
conquest of the world of scientific medicine!
A brilliant beginning has been made in
this campaign by the preparation of excel-
lent substitutes for cocaine, less toxic than
cocaine itself—by the elaboration of sal-
varsan, by the isolation in our own country,
SCIENCE
[N. S. Vou. XLVI. No. 1188
and the artificial production, of adrenalin,
a vital regulating principle produced by an
organ, the suprarenal capsule, in our bod-
ies. The isolation and exhaustive study by
Kendall of the active principle of the thy-
roid gland, which no doubt will be followed
by its artificial preparation, is a second
brilliant instance of American success in
this great field! When we consider the
countless number of animal preparations—
gland extracts, serums and antitoxins—the
pure active principles of which are all we
really want, but which are injected into us
or fed to us, with an extraordinary amount
of unnecessary and often harmful animal
matter, we can realize what a boon to hu-
manity this line of effort really means. Let
me emphasize again, it is chiefly a matter
of wise and foresighted legislation to make
our independence and perhaps our leader-
ship in this great field possible—we have
proved that we have the scientific ability
—it is a question only of putting this work
on the basis of an established industry !
There are other important considera-
tions bearing on the outlook for chemistry
in the United States from the point of view
of industrial chemistry—such as a law ma-
king possible commercial agreements and
divisions of labor among competing houses,
which exist abroad—but I must neglect no
longer to turn to the third important
theme embraced in my subject, the outlook
for chemistry from the point of view of our
universities and colleges, in which I will
include the outlook for the development of
the theory of our science in this country.
One can not well overestimate the im-
portance of the standing of chemistry in
our universities and colleges: they are not
only the main sourees of supply of chem-
ists in the United States, but they are also
the fountain-heads for the knowledge which
keeps us in touch with the progress of
chemistry the world over and which makes
available for rapid absorption in any field
Ooroser 5, 1917]
of pure or applied chemistry new discover-
ies, new methods of attack, new, clarifying
points of view. Let me remind you that
applied chemistry includes not only indus-
trial chemistry, but also fundamental and
most promising fields of effort in other
major sciences. Botany through the in-
spiration of Liebig was probably the first
of our sister sciences to apply chemistry to
the solution of many of its problems.
Physiology followed and now we see even
zoology awakening under the stimulus of
chemistry from its long morphological
trance to a live science of animal life. In
fulfilment of the promise contained in the
life of our great fellow-chemist Pasteur,
chemistry is now at last guiding not only
the physiologists, but also the bacteriolo-
gists, pathologists and laboratory clinicians
toward the raising of medicine from the un-
certain realm of art to the safer one of
science. All life is indeed but a transfor-
mation of matter in its loftiest phase and
the world is at last realizing that the
fundamental science of the transforma-
tion of matter holds the key which should
unlock the secrets of all aspects of life, of
birth, health, disease and death, and prob-
ably even of such subtler manifestations as
heredity and character.
I have outlined some of these far reach-
ing applications of chemistry in order to
emphasize the fact that if we are to meet
all of these demands on chemistry, if the
outlook not for chemistry alone, but for all
of these lines of human progress which are
dependent on our science is to be one of
sure promise in the United States, it be-
hooves our people to see that the depart-
ments of chemistry in our universities and
colleges be kept not only prolific as to the
output of men—the vast expansion in lab-
oratories and attendance bears witness to
quantity being insured if the war does not
affect us too severely—but that they also
bé maintained on such a high level of scien-
SCIENCE
329
tifie quality that the product will consist
of the very best type of men! We have re-
ceived from the period from which we are
now passing a magnificent heritage of world
standing and ideals in our university life.
The last twenty-five years witnessed an era
of expansion of our resources for research
and instruction, of the raising of standards
of scholarship and productivity of such
moment that many years before the war
began the migration of our students, espe-
cially also of our chemistry students, to
Europe for the pursuit of graduate work
and the securing of the highest type of pro-
fessional training had practically ceased.
It has no longer been a question of Berlin
or Munich, of Goettingen or Heidelberg ;
for the prospective chemistry student it has
been a choice of Harvard or John Hopkins,
of Chicago or Columbia, of Illinois or Cali-
fornia, the Massachusetts Institute of Tech-
nology or Cornell—I could extend the list
much longer, but fear it would tire you.
And it has been so because our young men
have felt that they could secure just as
thorough an education here as there, just
as inspiring guidance from men whose re-
search had made them masters in their own
fields. Our Remsens and Michaels, our
Richardses and Nefs, our Noyeses and Gom-
bergs, Lewises and Morses—to mention only
a few of our leaders of this period—
founded that independence in university
education in chemistry which our country
has the right to demand that we maintain.
Now, thoughtful men in our society,
looking ahead, see that this great uplift in
our scientific life is facing dangers which
unless they are met frankly and effectively,
will bring on a period of depression which
will be a grave menace to all the varied
fundamental interests in the life of the na-
tion that depend on chemistry.
The first and greatest of these menacing
developments has its root in the recent un-
precedented demand of our industries on
330
our schools for research men. From uni-
versity after university, from college after
college, the combined lure of great research
opportunities and of much larger financial
returns has taken from our academic life
far too many of our most promising young
men, the very men on whom the country
has been depending for the filling of our
great university chairs as the older men
now holding them gradually will age and
retire. Unless prompt measures are taken
we shall witness in a few years such a
dearth of first-class tried material for pro-
fessorships that second-rate men will be
placed where the national welfare needs
the best we have, and third- and fourth-
rate men will be occupying positions in
which we should have young men of the
highest promise in the period in which
they are reaching full maturity. Indeed,
it is greatly to be feared that even now we
are witnessing a gradual lowering of stand-
ards. It would be futile to appeal to our
industries not to call the men they need, al-
though in the not distant future they will
suffer most severely from the situation
which is developing, if the present tenden-
cies remain unchecked. The only possible
source of relief lies, I believe, with the
presidents and trustees of our great uni-
versities, and to these the second main plea
of this privileged discussion is addressed.
These authorities should recognize the fact
that their institutions have now entered a
period of severe competition between the
industries and academic life for chemists:
of the highest type and greatest promise.
They have already learned the only method
of meeting this kind of competition suc-
cessfully, for they have faced the same
problem in two other professions, medicine
and law: in the face of the tremendous
financial attractions of the practise of
either of these professions our most pro-
gressive universities have simply put their
SCIENCE
[N. S. Vou. XLVI. No. 1188
law and their medical faculties on a higher,
more nearly professional scale of endow-
ment of professorships than obtains for
their other faculties. They must, it seems
to me, take the same measures with their
chemistry staffs: it is primarily a question
whether they can be awakened to that need
now or whether they will let the country
suffer from their lack of foresight and let
us learn from the most efficient of our
teachers, bitter experience. Wise provis-
ion now would not only safeguard our pres-
ent standing in a critical period of our his-
tory, but in this time when the importance
of chemistry has been brought home to our
young men as never before, the new atti-
tude, properly announced, would attract a
large proportion of the men of brains, tal-
ent and ambition who enter professional
life, but tend to study law or medicine as
holding out much greater opportunities for
the satisfying of their ambitions.
Adequate compensation is important for
a research man—and to his type in uni-
versity and college I must restrict my re-
marks—it is important both from the point
of view of his self-respect and also espe-
cially for the sake of comparative freedom
from worry concerning a fair provision for
his family. But inadequate compensation
is not the only danger seriously threaten-
ing the outlook for chemistry in our uni-
versities. Let us remember that healthy
progress in our science is dependent pri-
marily on university men pursuing great
lines of original investigation. It is true
that we now have well-endowed national
institutions of research, such as the Rocke-
feller Institute and the Carnegie Institu-
tion, but universities can not afford to sur-
render to these the main burden of insur-
ing progress in the theory of our science,
because these are not teaching institutions.
To take from our universities the choicest
of our research men would deprive our
Octoser 5, 1917]
young men of that inspiration and fertiliza-
tion of their minds in the period of their
greatest acceptiveness which early intimate
association with great investigators alone
can give. To my mind it is clear that if
universities would fulfil their highest mis-
sion they must remain the seats of the best
type of research. But such research is the
product of an extraordinarily sensitive
state of mind. Only the greatest powers
of concentration of thought make it pos-
sible. The investigator is groping for truth
in unexplored regions, wary of every pit-
fall, most fearful indeed of possible illu-
sions of his own highly excited imagina-
tion. Let any one imagine himself groping
in a dark and unfamiliar room and he will
easily realize that the undisturbed concen-
tration of his every faculty is the only way
for him to attain his goal! Let the rush
of an automobile or the screech of a loco-
motive detract his attention but for an in-
stant and he may well have to rue a stubbed
toe or a grazed shin! Now, figuratively
speaking, there are too many noisy auto-
mobiles and screeching locomotives in the
lives of our distracted investigators. Amer-
ican universities, in general, have the un-
fortunate custom of loading down their
best investigators as heads of departments
with administrative duties of all varieties,
ranging from clerical functions to com-
mittee work, important for the institution,
but always a grave obstacle in the path
of successful research. Younger men, even
when they show marked research ability,
are too often worn out with excessive duties
of instruction and laboratory detail, when
their minds need their keenest edge to cut
their path to the elusive truth! Men in
whom the research instinct is inborn and
overpoweringly intense, will break through
these difficulties—usually at the cost of the
neglect of other duties—but our system is
one that means an extraordinary waste of
SCIENCE
331
talent for the highest type of work on
duties that minds of lesser fineness could
do just as well or better. On top of these
older defects, which we have been only
slowly recognizing and removing, have come
in the last few years the further distract-
ing duties of necessary public service. Let
me repeat what I stated earlier in the eve-
ning: every one of our great chemists, as
well as of our less well known ones, is eager
to devote every particle of his knowledge and
strength to the sacred duty of the moment.
Theoretical work has been set aside except
as it contributes directly to the cause of na-
tional defense. But let us begin to realize
now that when peace comes we must let our
investigators return to the service of pure
science, we must leave them severely alone,
free from committee work of any kind, so
that they may recover that opportunity for
concentration which is needed for produc-
tive research of permanent value! Some
of our research men, I dare say, are being
spoiled forever for this service, exactly as
many a returning soldier will have lost in
a craving for adventure his fitness for ordi-
nary civic responsibilities.
There is a strong movement too in our
society to bring universities and industries
into closer relations, a laudable movement
with which I am in heartiest sympathy, but
which can bring unmixed benefits only if
it is most wisely guided. It would be fatal
if it were allowed for the sake of temporary
advantage to injure in any way that search
for truth for the sake of the truth itself on
which, after all, the great structure of our
science as of all sciences rests. Let the
large proportion of members in our society
who are primarily interested in applied
chemistry, recall as a typical illustration of
a very general truth that chemists had
tried for fifty years to manufacture sul-
phuriec acid by the contact process and had
utterly failed, and that success finally
332
came only when the laws of physical chem-
istry, products of the research of guileless
university professors, were available and
were applied to the problem! Who can
doubt that we still need the efforts of new
Faradays, van’t Hoffs, Roozebooms, Bertho-
lets, Kekules! The question has impressed
me as so vital a one for the outlook for
chemistry in this country that as president
of our society I have put on the committee
charged with the development of relations
between industries and the universities pri-
marily university research men, with the
understanding that they will give to pure
research in our universities the benefit of
every doubt in their recommendations. I
trust that our society, as a whole, will
realize that it were better that our indus-
tries suffer somewhat temporarily than that
our national strength in chemistry be
crippled at the source. My personal opin-
ion is that we can attain both of our objec-
tives—to use a war phrase. Thus, our pres-
ent war duties are making university men
personally acquainted with numerous prac-
tical problems which in many cases after
the war, will probably form the basic ma-
terial for investigations of theoretical rela-
tions. Even if they are only in a measure
as successful as those of Baeyer, when
through the study of the structure and
synthesis of indigo he opened up the great
theoretical fields of knowledge of tautomer-
ism, of the theory of unsaturated com-
pounds and of eyelic derivatives, they will
advance both branches of our science, ap-
plied and theoretical chemistry. Efforts
along the lines of developing the theory of
the connection between molecular structure
and physiological or medicinal properties
_ are now taking root in a number of our uni-
versities. But, on the whole, I would rec-
ommend that technical research problems—
routine analytical and control work should
be altogether barred from our universities
—that technical research problems be lim-
SCIENCE
[N. S. Vou. XLVI. No. 1188
ited in universities to picked men interested
in applied chemistry and holding possibly
professorships or other appointments in in-
dustrial chemistry. In time, these men will
become dependent on their colleagues de-
voted to pure science for keeping step with
the progress in our science. I would urge,
too, the perhaps novel recommendation that
remuneration for such work be made a
departmental and not an individual affair.
This wise provision is being enforced in
those modern medical schools which de-
mand research work of their staffs, fees for
practise reverting to the university hos-
pitals and not to the individual. As ap-
plied to chemistry, such a provision would
be desirable, in the first place, because it
would to a large extent reduce the tempta-
tion of financial inducements for the men
whose talents fit them for work in pure
science and whom the country needs for
such work. In the second place, one will
find that the university man interested
in a technical problem is, after all, less use-
ful in a teaching department than the man
devoted to pure research: the pressure from
outside will lead him to throw a greater
mass of administrative detail, of instruc-
tion or of the care of research men, on his
colleagues. The result is that the depart-
ment and not the individual really carries
the burden of the problem in applied chem-
istry—exactly as in the medical schools,
which still allow their staffs to practise for
their own financial benefit, this is all too
often done with the drawbacks of ineffi-
cient teaching, the ignoring of administra-
tive responsibilities and the leaving to the
care of others the provisions for education
in research.
I have dwelt on the details of this great
problem which is confronting our society,
because I would protect the outlook for the
growth and success of theoretical chemis-
try in our country by every means in my
power. We have a splendid record: we
Ocroser 5, 1917]
are easily leaders in the domain of knowl-
edge based on the exact determinations of
atomie weights—a knowledge which leads
among other results to habits of more exact,
more critical methods in all fields of our
science. Arrhenius told us that America
is leading in the difficult work of the rigor-
ous examination of the theory of ionization
and of establishing it on a finished basis.
The development of the field of free energy
relations is more intensely cultivated, here
I imagine, than in any other country. In
the application of modern theories of
atomic structure and of the electron theory
of valence to all branches of chemistry,
especially also to organic chemistry, we are,
I believe, easily in the front. Our very
youth, as a people, has preserved to us in
science as in national sentiment, that whole-
hearted enthusiasm for ideals, which in
world politics has made us the most al-
truistic nation on the face of the earth and
which in science finds its expression in the
pursuit of knowledge for the sake of the
pure truth alone, a pursuit characteristic
of the best research in our universities and
colleges !
And so let me conclude my remarks on
the outlook for chemistry in America by
emphasizing that we have a goodly heritage
of success both in our great industries and
in our great universities, which will form
the safe basis of a brilliant future, if we
will but approach the problems of the mo-
ment and of the immediate future in char-
acteristically American fashion, with a
spirit wisely combining altruistic principles
with practical, worldly common sense.
This means the ‘‘ square deal’’ in indus-
trial life for the product of the brains of
the research chemist, combined with wise
laws to insure to capital a fair and toler-
ably safe return for investment in chemical
industries, needed to make our country
chemically independent. And it means too
SCIENCE

the placing of chemistry in our universities
on a plane with the other great professions,
law and medicine, in order to hold in this
great science, so important for the welfare
of the nation, the needed numbers of men
of brilliant minds and energetic ambitions
—combined with the devotion on their part
to the search for the truth, for the estab-
lishment of the great laws of our science,
for the sake of that truth, that science,
alone!

EFFECTS OF THE WAR ON TECHNICAL
EDUCATION
WALTER HuMPHREYS, registrar of the Massa-
chusetts Institute of Technology, has compiled
registration statistics which indicate the effects
of the war on technical education. The total
registration is between eighty-five and ninety
per cent. of what it was last year at the same
time. The freshman year shows an increase,
the percentage in terms of last year’s figure
being 104, while the second, third and fourth
years classes are respectively 93 per cent., ‘75
per cent. and 86 per cent., of the number in the
school in June.
The graduate students stand at 60 per cent.
of last year’s figure. There is the most shrink-
age in the juniors, the sophomores of last year,
to whom two years more of schooling has per-
haps seemed a long time. The return of eighty-
six per cent. of the juniors to be seniors is evi-
dence in favor of the junior summer camp.
The purpose of this was to give some military
practise and an opportunity to anticipate
fourth-year studies, and complete work at an
earlier date.
In a consideration of the effect on the courses
it may be well to omit those with less than fifty
men, since the defection of a few students
makes an undue percentage shrinkage. One of
them, however, naval architecture, is stimu-
lated by the war, the increase béing 16 per
cent. The course in naval architecture has al-
ways been small in attendance and has been
maintained by the institute as a contribution
to education.
Of the larger courses civil engineering main-
tains practically the same figure as in former
years, the shrinkage being 1.2 per cent., while
electrical engineering opens the year with a
loss of only 2 per cent. Chemical engineering
has 12 per cent. increase. Engineering admin-
istration is practically holding its own, having
lost only six and one half per cent. since the last
registration. Architecture has declined nearly
one third in the number of its students. Per-
haps the undue cost of building materials, fifty
to one hundred per cent. in many cases, and
the consequent gossip that building operations
will be at a standstill, has had its influence in
deterring young men from taking it up with
Qctoser 5, 1917]
usual vigor. Mechanical engineering has lost
about 21 per cent. This is a study that should
be stimulated by the war. In this work Pro-
fessor Miller, head of the department, has
undertaken for the U. S. Shipping Board the
management of the schools for marine engine-
room officers in the principal ports in the coun-

WORK OF THE NATIONAL RESEARCH COUNCIL
Upon recommendation of the National Re-
search Council Dr. Augustus Trowbridge, of
Princeton University, and Professor Theodore
Lyman, of Harvard University, have received
commissions in the Signal Corps, U. S. A., for
work in sound ranging. They have sailed for
France to investigate conditions at the front
in this subject. The sound ranging service
which will be developed under their direction
will utilize in the near future more than fifty
men. Captain Horatio B. Williams is in
charge of the development work in this country
during Major Trowbridge’s absence.
A meteorological service has been organized
under the Signal Corps, U. S. A., in which
about one hundred physicists and engineers
will be engaged in aerological observational
work under the direction of Dr. William H.
Blair, of the U. S. Weather Bureau, who has
received a commission of major and has sailed
for France to investigate conditions abroad.
Forecasting work for the American Expedi-
tionary Force in France will be in charge of
Mr. E. H. Bowie, of the U. S. Weather Bu-
reau, who has likewise received a commission
of major in the Signal Corps and is already
on his way to France. Major Bowie will be
assisted by Mr. R. Hanson Weightman, of the
U. S. Weather Bureau, who has received a
commission as lieutenant in the Signal Corps.
Professor Charles E. Mendenhall, of the Uni-
versity of Wisconsin, has received a commis-
sion of major in the Signal Corps, U. S. A.,
and has been placed in charge of the develop-
ment of aeronautical instruments.
All of the work of these services, sound-
ranging, meteorology and aeronautical instru-
ments, is included within the scope of the Sci-
ence and Research Division of the Signal
Corps, which in accordance with a recent order
SCIENCE
309
of the chief signal officer has been established
and placed under the direction of the National
Research Council, of which Major R. A. Milli-
kan is the executive officer. The functions of
this division of the Signal Corps are two-fold,
namely: (1) to furnish personnel of the re-
search sort to the other divisions when the
situation warrants the assignment of men of
this type to these divisions, and (2) to have a
personnel of its own which maintains intimate
contact with all research and development
work in other divisions, and distributes re-
search problems to university, industrial and
governmental research laboratories with which
it is associated. Similar, though in some cases
less formal, relations have been established
with other technical bureaus of the War and
Navy Departments.
Upon request of the French High Commis-
sion a number of American physicists and
chemists are being sent to France to assist in
various war problems in which technically
trained men are needed. Except in certain
cases, the Interministerial Commission in
Paris will assign them to work in university
laboratories and in technical services of the
government. Upon recommendation of the
National Research Council the following men
are receiving commissions in this connection
and a number of them have already sailed for
France:
Professor R. W. Wood, of Johns Hopkins Univer-
sity, major in the U. S. Signal Corps.
Messrs. Roy W. Chestnut, Leonard Loeb and
Samuel Sewall, lieutenants in the U. 8S. Signal
Corps.
Professor Edward Bartow, of the University of
Illinois, major, and Professor Reston Stevenson, of
the College of the City of New York, captain in the
U. S. Sanitary Corps.
Messrs. Ralph L. Brown, of the University of
Chicago, George Scatchard, of Columbia Univer-
sity, and Kirke W. Cushing, of Western Reserve
University, lieutenants in the U. S. Sanitary Corps.
SCIENTIFIC NOTES AND NEWS
THE trustees of Columbia University have
dismissed Professor J. McKeen Cattell from
the chair of psychology which he has held
since 1891, on account of a letter which he
336
addressed to members of the Congress, asking
them to support a measure which had been
introduced against sending conscripts to fight
in Europe against their will. Professor Cat-
tell has given out a statement in which he
says that he is opposed to war and to this war,
but that he has engaged in no agitation
against the government, and has not written
anything opposing conscription or against
sending an army abroad. He maintains that
forcing “conscientious objectors” to fight in
Europe is not only contrary to democratic
principles, but also subversive of the efficiency
of the army and of national unity. He claims
that it is the duty as well as the constitutional
right of a citizen to petition the government
to enact legislation believed by him to be for
the national welfare. For a university to dis-
miss a professor for doing this is both unjust
and illegal. Under the circumstances Pro-
fessor Cattell believes that it may be in the
interest of Science and of the American As-
sociation for the Advancement of Science for
him to retire from the editorship which he
has held for twenty-two years. He has ad-
dressed a letter to the chairman of the Com-
mittee on Policy of the Association request-
ing that a successor be selected.

AccorpInG to the London correspondent of
the Journal of the American Medical Associa-
tion official statistics show that on an average
there has been an increase in food prices of
104 per cent. compared with July, 1914, the
month before the war began. The increase
varies from 65 per cent. in the case of fresh
butter to 191 per cent. in the case of certain
parts of frozen mutton. The average price of
bread—23 cents for the 4-pound loaf—is
double that in July, 1914, and flour shows a
proportionately greater advance, amounting to
109 per cent. The price of granulated sugar
had risen over the war period from an average
of about 4 cents to nearly 12 cents per pound,
but increased duty accounts for about 2.5 cents
of the rise. The average price of cheese is
slightly more than double than in July, 1914;
that of eggs, slightly less than double. The
price of tea is 74 per cent. higher, but about
half of the advance is due to increased taxa-
tion. Butter and margarin show increases ap-
proximating to 65 and 74 per cent., respec-
tively, over pre-war prices. Milk prices had
risen 60 per cent., or 4 cents’per quart. In ar-
riving at the general percentage increase, the
several articles are weighted in accordance
with the proportionate expenditure on them in
pre-war family budgets, no allowance being
made for the economies resulting from
changes in dietary which have been effected
since the beginning of the war, especially in
those families in which the total income has
not been increased by advances in rates of
wages, greater regularity of employment, in-
creased output, or the working of overtime.
As an illustration of possible economies in this
direction, if eggs are omitted from the dietary,
margarin substituted for butter, and the con-
sumption of sugar and fish reduced to one
half of that prevailing before the war, the gen-
eral percentage increase since July, 1914, in-
stead of being 104, would be 72. During last
month alone the general level of retail prices
of the principal articles of food rose about 1
per cent. The prices of British beef increased
338
about 5 per cent., and those of other meat from
3 to 4 per cent. Bacon and fish showed some
decline in price as compared with a month ago.
In connection with work in food conserva-
tion the railway freight claim agents in Texas
are opening the way for cooperation with other
agencies interested in food production. On
Saturday, August 4, representatives of three
of the important railways in Texas met in
conference with Dr. J. J. Taubenhaus, of the
Texas Experiment Station, and Dr. F. H.
Blodgett, of the Agricultural Extension Serv-
ice, to discuss methods by which losses in
transit may be reduced in shipments of per-
ishable farm products. The matter was dis-
cussed both from the point of view of the
claim agent in reducing the financial expendi-
ture in settling damage claims on the part of
the shippers and others, and from the point of
view of food conservation, since the damaged
products, for which claims may be filed and
paid, draw from the food supply of the coun-
try with no benefits to any one since even dam-
age claims only partially represent the true
value of the products concerned. Plans were
outlined for the investigation of the unknown
factors involved by the pathologist of the Ex-
periment Station, and for the cooperation be-
tween the Extension Service and the railway
agricultural agencies to disseminate informa-
tion in regard to the different modes of hand-
ling produce to eliminate losses through shift-
ing of cargo and other causes which are already
well understood but not always carefully prac-
tised.

the army for the care of the National Guard
and National Army camps will cost about $14,-
500,000. The aim of the medical department
is to have hospital provision for 5 per cent. of
the enlisted force by fall, and then extend it to
10 per cent. Abroad, facilities for 20 per cent.
of the American expeditionary forces will be
available. Provision will be made at the can-
tonments in this country for 3 per cent. of the
troops in each camp. Each hospital with the
space reserved for extensions will require sixty

acres. The buildings will be 24 feet wide, the
length varying to meet the needs. A ward
about 157 feet long will accommodate 32 beds.
A cantonment hospital on a basis of 1,000 beds
will include about 70 buildings, if each ward
is considered as a building. Adequate labora-
tory facilities will also be provided, and plans
are being made to appoint permanently to the
staffs of the hospitals, men especially trained to
do laboratory work in order that careful tests
may be made of each and every soldier for
tuberculosis, intestinal infections, and all
other infectious diseases.
In Kansas a deep well struck rock salt at 690
feet below the surface and penetrated 600 feet
of rock salt in beds from 5 to 60 feet thick, ac-
cording to the United States Geological Sur-
vey. A large area in this state is underlain by
salt, which is mined by many shafts and ob-
tained by pumping brine. Drilling for oil in
Texas and Louisiana has revealed the presence
of tremendously thick deposits of rock salt at
a depth of a few hundred feet. Thicknesses of
2,000 feet are common, and one drill hole
passed through more than 3,000 feet of rock
salt. Most of the salt made in Utah is pro-
duced by evaporating the waters of Great Salt
Lake, and in California by evaporating sea
water. These sources are inexhaustible, and
the limit of production by solar evaporation
will therefore never be reached.
The Electrical World states that for several
years past from fifteen to thirty engineering
teachers have spent part of the summer vaca-
tion at the East Pittsburgh works of the West-
inghouse Electric and Manufacturing Com-
pany in getting acquainted not only with the
apparatus manufactured by this company, but
also with its engineering designers, commer-
cial engineers and works executives. This
year there were twenty-four men from seven-
teen different states and from Canada and
Japan, representing twenty-three different
engineering schools. Most of their time is
spent on actual work, either on assembly or
test floor or in the engineering offices, but part
of the time is given up to a series of meetings,
which include inspection and discussion of ap-
paratus being manufactured, talks on engi-
Oocroper 5, 1917]
neering opportunities and requirements, dis-
cussions of teaching problems, excursions to
other plants and social meetings. This course
gives engineering teachers an opportunity to
become acquainted with the latest develop-
ments in electrical power apparatus, with shop
methods in use in large manufacturing con-
cerns, and to meet and exchange ideas on
teaching subjects with other engineering
teachers of experience. Since the Westing-
house company draws men from engineering
schools, it is of advantage to it that students
may know not only of the opportunities open
but of methods of working efficiently in its
organization.
UNIVERSITY AND EDUCATIONAL
NEWS
Dr. Joun R. Muruin, for eight years as-
sistant professor of physiology in the medical
school of Cornell University, has been ap-
pointed director of the new department of
vital economics at the University of Rochester.
This department is being organized from
funds made available by the will of Lewis P.
Ross, whose will gave to the university the
residuary estate of more than $800,000, the
income only to be used “to the end that
human life may be prolonged with increased
health and happiness.” The trustees were in-
structed to expend that income for two pur-
poses—to contribute toward the support, im-
provement, and extension of the department
of household economics of the Mechanics’ In-
stitute of Rochester, and to establish in the
university a department of vital economics.
Dr. Murlin is now a major in the Sanitary
Corps of the national army, and head of the
food division in the surgeon general’s office.

DISCUSSION AND CORRESPONDENCE
WHEN IS A FORCE NOT A FORCE?
In his communication to Scmnce for March
16, 1917, Mr. A. H. Patterson very pertinently
calls attention to the vagueness, lack of pre-
cision and error in the treatment of the force
concept by current physics text-books. Much
of Mr. Patterson’s criticism deals with New-
ton’s third law of motion and appears to be
based on a misinterpretation of that law. To
this I wish to call attention.
Force is always exerted by one portion of
matter, A, upon a second portion of matter B.
These may be distinct bodies or parts of the
same body. If A exerts a force on B then,
the third law tells us, B exerts an equal force
in the opposite direction on A. If the force
of A on B is called the action, the force of
B on A is called the reaction. The action and
reaction do not act on the same body or body-
part. Failure to fully appreciate this seems
to be responsible for the present as well as
many other misinterpretations of the third
law.
Mr. Patterson asks: “ What is a student to
think when he is told that to every action
there is always an equal and contrary action,
and is then informed that (only) an unbal-
anced force acting on a mass produces ac-
celeration?” The two statements are mutu-
ally consistent and true. In order to safe-
guard the student against some of the pit-
falls which are dangerous even to his teachers
it is only necessary to make the information
more complete.
Mr. Patterson’s problems may well serve this
purpose. The ball at the end of a rubber
band is the first of these. Let us ignore the
effect of gravity. When the ball is whirled
about in a circular path at uniform speed the
pull exerted by the rubber band on the ball
is called the centripetal force. No other
balanced force and gives rise to an acceler-
ation which manifests itself in the change
in direction of the velocity. The equal and
contrary action is the outward pull of the
SCIENCE
.[N. S. Vou. XLVI. No. 1188
ball on the string, known as the centrifugal
force. The string is not accelerated because
the pull of the support at the fixed end is
equal and opposite to the centrifugal pull at
the free end. The forces on the string are
balanced.
A porter pushes a truck at uniform speed
over level ground. Then the force which he ~
exerts forward on the truck is equal to the
backward frictional force. If this frictional
resistance were suddenly to vanish, the for-
ward force exerted on the truck by the porter
would be the only horizontal force, hence un-
balanced and a forward acceleration would re-
sult. Both with and without friction the
truck pushes backward on the porter with an
equal force. In addition to pushing forward
on the truck the porter is pushing backward
on the ground with his feet, and consequently
the ground is pushing him forward. If the
forward push of the ground and the backward
push of the truck are equal the forces on the
porter are balanced and he moves without
acceleration. Everywhere the forces act in
pairs, because there must be an exerter of the
force and a body on which it is exerted.
Newton’s law has a meaning only when both
bodies are considered.
Newton’s third law requires no distinction
between inertia-reactions and other forces.
To introduce them serves to complicate rather
than to simplify. The following problem
utilizes Mr. Patterson’s method, quoting
freely from the closing paragraphs of his
communication.
A mass M rests on a perfectly smooth
horizontal surface. To M we apply a hori-
zontal force F. Being the only horizontal
force it is unbalanced. It is opposed by an
inertia reaction which can in a sense balance
it, but can not hold it in equilibrium because
a force opposed only by inertia reaction always
produces acceleration.
It is difficult to see the need of this devital-
ized form of the third law, either from the
point of view of principle or of practice.
Forces do always exist in pairs, yet the
forces on either or both of two bodies between
which force-action exists may be unbalanced.

none exists and then proposes an artificial
way out. E. A. Eckuarpr

THE THIRD LAW OF MOTION AND
“INERTIA REACTION”
THE recent article by Mr. Andrew H. Pat-
terson in Scmnce for March 16, 1917, impels
me to add to the discussion of questions in
mechanics something that I have tried to make
clear to students. It is along the line of Mr.
Fulcher’s article of November 24, and con-
cerns the confusion between the third law of
motion, the second law, and D’Alembert’s
principle.
Mr. Patterson appears to object to teaching
that “to every action there is always an equal
and contrary action” or that “forces always
occur in pairs” and at the same time that an
“mbalanced force”? produces an acceleration.
There is surely no inconsistency in this, since
the “pairs” of forces or the action and re-
action act on different bodies, say A and B,
then if no other bodies are acting upon them,
there will be an unbalanced force on each,
and each will be accelerated, but in opposite
directions. Evidently another pair of forces
may act between B and C such that on the
whole the forces on B exactly balance, and yet
A will be left with an accelerated motion.
On the other hand, while it is clear from writ-
ing the equation representing the second law
of motion in the form #—Ma=0, that
if a force equal to the mass times the acceler-
ation should act on the body in the opposite
direction to the impressed force, these forces
would be in equilibrium, this is not a case of
the third law, which specifies that the forces
considered act between two bodies and not
on one and the same body. If for a system
one adds the idea (D’Alembert’s principle?),
that the internal actions and reactions of any
system of bodies are in equilibrium among
themselves, a special case of the third law,
one obtains the more general statement that
af forces equal to the several masses times
their respective accelerations were applied,
SCIENCE
341
ete., a form which is useful in the handling
of problems, but which does not imply that
such forces are acting and does not call for
the idea of “inertia reactions.”
The case where “inertia reaction” is most
frequently drawn in, in connection with action
and reaction is the instance of an object being
whirled around on the end of a string. Now
when one explains the motion of the moon
about the earth as due to the action of the
gravitational force on the moon directed tow-
ards the earth, one looks for the “reaction”
in a gravitational force on the earth directed
toward the moon, but not a force on the moon,
and this reaction on the earth has nothing to
do with the mass & acceleration of the moon,
but would be the same if the moon were at
rest in the position which it has at any in-
stant. Is not the same true for the ball and
string? Consider the case where a person
grasps the ball by a hook at the end of a di-
ameter, and pulls on a cord at the other end
with the force F’, the ball as well as the cord
is strained, and we may say that the ball is
pulling on the string and the string on the
ball (the third law), in virtue of this strain.
Now let go at the one end, in order to continue
to apply a force F the hand must be moved
with the same acceleration which the ball has
in order to keep the string stretched, and
would not the ball in the neighborhood of the
string remain strained as before and hence
the forces between ball and string be of the
same nature as before? Now suppose the ball
swung around the head, as Mr. Patterson sug-
gests, would not the ball still remain strained
and would it not pull on the string with a
force which would be exactly the same as if
the ball were at rest, but in the same state of
strain? If so why bring in an inertia reac-
tion? In the illustration of the porter push-
ing a cart, as long as he actually pushes there
is an equal counter force on him, but in the
one case the push on the cart may be balanced
by friction, and in the other it would be an
unbalanced force on the cart. Actually if
friction suddenly ceased would not the porter
probably notice that the force with which he
was pushing had suddenly diminished, and
342
that he had to hurry up to push at all? It
would seem to me to be true in this case also
that the push back on him would be the same
if the cart were in the same state of strain and
at rest.
If the point of view brought forward here
is correct it would seem to me desirable to
leave out of any elementary discussion of me-
chanics an “ inertia reaction.”

AN ADDITIONAL NOTE ON “THE OOLITIC
AND PISOLITIC BARITE FROM THE
SARATOGA OIL FIELD, TEXAS”
Agout three years ago the writer wrote a
description of some barite of unusual type
from the Saratoga Oil Field, Texas. Speci-
mens of this mineral have been brought to the
surface in pumping, and they have been found,
in all cases reported to the writer, at a depth
around 1,200 feet, indicating that they prob-
ably have their source in a definite geological
horizon. At the time the above-mentioned
paper was written it was supposed that the
concretions of this mineral originated with
the sands in which they were found but there
was no definite information on the subject.
In discussing this matter a short time ago
with Mr. E. G. Woodruff, he stated that at
least some of these concretions undoubtedly
formed in the wells after they were equipped,
because they had been found reaching a quar-
ter of an inch in diameter, in a well with a
screen on the tubing, the mesh of which was
altogether too small to admit a concretion of
the size stated. He kindly sent the writer an
assortment of specimens of various shapes and
sizes from other wells in the same field as
those previously described and of approx-
imately of the same depth. Tests with the
blow-pipe and specific gravity determinations
show that the composition of the concretions
is almost identical to that of those previously
described. A number were examined for
nuclei, but in most cases no definite nucleus
could be found. When a nucleus is present

it consists of earthy material made up mostly
of clay and barite and this mass is often
stained with iron ioxide which gives the cen-
ter of the concentration a brownish tint.
This additional information is interesting
from the standpoint of its bearing on the
origin of concretions. It would appear to be
practically impossible for bacteria or other
low types of life, which are believed to play
an important part in the origin of odlites, to
exist in a liquid with such strong antiseptic
properties as those of warm petroleum con-
taining considerable sulphuric acid. It would
seem to demonstrate that living organisms
are not essenial to the development of odlites
and that these may form where precipitation
is taking place in an agitated solution, in the
absence of life. - E. 8. Moore

Ocean Magnetic Observations, 1905-1916, and
Reports on Special Researches. By L. A.
Bauer, Director, with the collaboration of
W. J. Perers, J. A. Fuemine, J. P. Aut
and W. F. G. Swann. Washington, D. C.,
1917. Carnegie Institution. Pp. vii + 447.
This large and handsome volume is the third
of the series issued by the department of ter-
restrial magnetism of the Carnegie Institution
and contains full reports of all the magnetic
work of the department at sea during the past
eleven years. The two preceding volumes deal
with the observations on land for the periods
1905-1910 and 1910-19138 respectively.
In 1905 the wooden brigantine Galilee was
chartered at San Francisco and fitted up for
magnetic observations with the purpose of ma-
king a preliminary survey of the Pacific Ocean
which was at that time “nearly a blank as re-
gards magnetic observations.” In the course
of three years, this vessel cruised 63,834 nauti-
eal miles and, magnetically speaking, put the
Pacifie Ocean “on the map.” In addition to
the great number of valuable and accurate ob-
servations which were accumulated, these
eruises of the Galilee afforded an opportunity
for testing and improving magnetic instru-
OctosEr 5, 1917]
- ments adapted to sea-conditions, for establish-
ing a practicable and suitable routine of ob-
serving and of checking instruments and in
general for learning how to make magnetic ob-
servations at sea far more accurately and
systematically than had ever before been at-
tempted.
The “magnetic constants” of this wooden
sailing vessel were smaller than those of any
vessel which had been previously used for mag-
netic observations; but, small as they were,
they necessitated many corrections and fre-
quent “swinging the ship” to obtain the ac-
curacy which Dr. Bauer had determined upon
as the goal to be attained. This not only con-
sumed much time, but also diminished the pre-
cision of the final results. Accordingly, the
non-magnetic yacht Carnegie was built in
1909 in which the use of iron was almost
wholly avoided; wooden pins, and bolts of
copper and of Tobin bronze took the place of
iron nails, the producer gas engine used for
auxiliary power was constructed of bronze,
and the only magnetic materials used were the
steel valves, piston rings and cam-rollers. Re-
peated tests have shown that this unique ves-
sel has no appreciable effect upon the instru-
ments; and in her various cruises aggregating
more than 160,000 miles, observations have
been obtained with comparative ease and ra-
pidity whose accuracy is far beyond anything
which had previously been possible at sea.
The first 154 pages of the present volume
give an account of the work done on the
Galilee, while the remainder deals in the same
way with the observations made on the Car-
negie. The various instruments are fully de-
scribed and illustrated, and it is most interest-
ing to follow their gradual improvement and
perfection. To the experimental physicist this
is one of the most attractive portions of the
report; especial mention may be made of the
beautiful and ingenious marine earth-inductor
described on pp. 196 et seq. A full account is
given of the methods of making observations,
their reduction and correction and of the sys-
tem of checks and controls between the various
instruments, as well as those introduced by
shore observations which were made at every
SCIENCE
343
opportunity. The final results for each cruise
are given in tabular form and no detail is
omitted which might add to their usefulness.
In addition to the magnetic measurements,
systematic observations were also carried out
on atmospheric electricity, ionization and
radio-activity; these form the subjects of the
special reports with which the volume closes.
The practical utility of this great series of
magnetic observations in correcting mariners’
charts of magnetic variation is obvious; seri-
ous errors in the present charts have been
found and their correction lessens the dangers
of navigation in times of storm and fog when
astronomical observations are impossible.
And quite apart from this most useful result
the ultimate scientific value of such a survey
continued year after year, as it will doubtless
be when the war is over, is very great. The
earth’s magnetism is one of the great myste-
ries of physical and cosmical science; observa-
tions on land alone cover too small an area of
the earth’s surface to afford an adequate basis
of knowledge of the earth’s field and of the
intricacies of its secular variations. Con-
tinued, systematic sea observations of the
accuracy of those recorded in this report form
a necessary stage in the solution of the great
problem; when that is obtained it will doubt-
less lead to a further knowledge of the sun’s
magnetism and may well have results of the
highest significance in cosmical theory.
This volume is a monument to the well-
directed enthusiasm and foresight of Dr. Bauer
and to the skill and zeal of his associates. In
this case as in many others the Carnegie In-
stitution deserves the thanks of the scientific
world for generously supporting and wisely
forwarding work which could scarcely have
been done at present by any other agency.

THE RELATION OF THE MALPIGHIAN
TUBULES OF THE HIND INTES-
TINE IN THE HONEYBEE
LARVA
Ir has been known for nearly a hundred
years that the mid-intestine of larvee of bees
344
and wasps was essentially a blind sac.1 The
subsequent establishment of communication
between the mid and hind-intestine in the
larve of various members of the Hymenoptera
was long since noted and has been studied in
detail by Rengel.2 The relation of the Mal-
pighian tubules to the hind-intestine in the
Hymenoptera has, on the other hand, been
strangely neglected, being mentioned only in-
cidentally or completely ignored. For example,
both Anglas? and Rengel merely state that in
the late larva or semipupa of the honeybee the
Malpighian tubules open into the hind-intes-
tine, and ignore the earlier stages. Kara-
waiew! and Perez® describe the Malpighian
tubules in the ant larva as opening into the
hind-intestine. This condition, however, does
not obtain in case of the feeding larva of the
honeybee, the central (caudal) ends of the tu-
bules being blind from the time of hatching
up to the sealing of the cell. The relation of
the tubules to the hind- and mid-intestine dur-
ing the feeding period is briefly as follows:
The posterior end or fundus of the mid-intes-
tine is, as already stated, completely closed,
the epithelium being continuous here. The
cephalic end of the hind-intestine is enlarged
and the mouth of this enlargement closed by
a thin diaphragm-like layer of cells contin-
nous marginally with the wall of the hind-in-
testine The central part of this diaphragm-
like structure is closely applied to the external
surface of the fundus of the mid-intestine
which is here devoid of a muscular coat. The

pointed central blind ends of the four Mal-
pighian tubules are inserted between these
two layers, two on each side, but their tips do
not extend quite to the center of the area of
attachment of the mid- and hind-intestines.
In the newly hatched larva the Malpighian
tubules are slender tubes, and pursue a wind-
ing course from their point of attachment up
to the second or third thoracic segment, lying
between the capacious mid-intestine and the
body wall. Their lumen is minute, the walls
being relatively very thick and composed. of
cells whose depth and breadth are approxi-
mately equal. In the mature larva on the other
hand the Malpighian tubules are relatively vo-
luminous, attaining, near their posterior ends,
a diameter greater than that of the hind-in-
testine. The posterior or central ends them-
selves, however, always remain of small di-
ameter. Sections through the tubules at this
stage show that the walls are extremely thin
and composed of flat cells. In fact, the tu-
bules might well be described as “ thin-walled
tubular sacs.” Evidences of distension by in-
ternal pressure are obvious.
After the larva has been sealed up in its
cell by a waxen capping both the fundus of the
mid-intestine and the diaphragm-like epithe-
lium closing the cephalic end of the mid-in-
testine become perforated, thus establishing an
avenue of communication between the mid- and
hind-intestine through which the fecal ac-
eumulations of the mid-intestine are expelled.
At the same time that this occurs each of the
Malpighian tubules establishes connection with
the hind-intestine by means of a fine canal
which perforates the diaphragm-like layer of
cells which formerly closed the anterior end
of the hind-intestine but which now forms an
annular structure uniting the mid- and hind-
intestines. Sections through the tubules show
that they have greatly diminished in calibre,
the walls being more or less collapsed and their
component cells being correspondingly nar-
rower and deeper.
The history of the Malpighian tubules and
that of the mid-intestine during the feeding
period of larval life are therefore parallel in
that both, in addition to performing their
SEPTEMBER 21, 1917]
original functions, retain and store up the ac-
cumulated excreta which is discharged only
after feeding ceases, when such discharge on
the interior of the cell occupied by the larva
would not involve contamination of the food.

CONCERNING THE EFFECT OF INGESTED PLA-
CENTA ON THE GROWTH-PROMOTING
PROPERTIES OF HUMAN MILK
Ir has been shown that the feeding of desic-
cated placenta to women during the first eleven
days after parturition causes an increase in
the protein and lactose per cent. of the milk.t
The present report is concerned with the
growth of the infants subsisting upon the milk
from the above sources. As a basis for com-
parison there is used the growth of the infants
whose nourishment was derived from the wo-
men whose milk production was not subjected
to the influence of ingested desiccated pla-
centa. ;
In the tables at the end of this paper the
number assigned to the infant corresponds to
the number given to the mother in the previ-
ous reports. It should be remembered that all
the mothers were receiving the same diet and
that to the second set 0.6 gm. of desiccated pla-
centa was fed three times a day throughout the
period. }
Certain definite differences in the progress of
growth of the two sets of infants are to be ob-
served.
The variation limit per cent. from day to
day, and the absolute per cent. variation from
day to day is less in degree and tends to take
on more of a positive character in those in-
fants whose mothers were fed the desiccated
placenta. Also the per cent. variation from
the first day, both as regards its limits and its
average is at all times less in degree. The gen-
eral trend of these latter values is towards
zero; this is not to be seen with the infants
receiving milk from uninfluenced sources.

It is evident that the recovery from the post-
natal decline in weight is hastened by the con-
sumption of milk produced under the influence
of maternally ingested placenta.
It is obviously possible to eliminate from
consideration the increase in protein and
sugar production induced by the placental
feeding as the cause of the early weight in-
crease.

These results may then be best interpreted
on the assumption of the presence of some
growth-promoting factor in the ingested pla-
centa, which has been passed on to the infants
in the milk. There is thus opened up the prob-
ability of the placenta taking some part in

intra-uterine growth aside from its function
as a transfer system.

THE EFFECT OF DRAINAGE ON SOIL ACIDITY
For the purpose of studying the effect of
drainage on soil acidity, samples of soil were
taken in October, 1916, from three of the ex-
periment fields of the Purdue Agricultural Ex-
periment Station. These fields are located
near Westport, North Vernon and Worthing-
ton. The soils of these fields are all heavy silt
loam, very low in organic matter and naturally
poorly drained and quite acid in reaction. All
of these fields have been thoroughly tile
drained from three to five years. A portion of
the Westport field is undrained and there are
adjacent undrained, untreated areas alongside
the North Vernon and the Worthington fields.

Table I. shows the acidity of the soil as de-
termined by the potassium nitrate method.
Without entering into a discussion of the
merits of different soil acidity methods, it may
be said that on these soils, which are low in or-
ganic matter, there is no great difference in
the degree of acidity shown by this method
and the lime water and calcium salt methods.
These results are consistent enough to indicate
that drainage has a material influence on the
acidity of soil of this type.
Farmers often refer to wet, poorly drained
land as sour. While agricultural writers have
placed little or no emphasis on such a correla-
SCIENCE
[N. S. Vou. XLVI. No. 1186
tion, it is quite probable that soils in general
will tend to become less acid when thoroughly
drained, and vice versa; they will tend to be-
come more acid when water-logged and poorly
aerated. In testing soil acidity at different
seasons of the year the results often vary quite
a little in samples from the same plots of soil.
These differences can not be attributed alto-
gether to errors in sampling. The writer be-
lieves that at least part of the change of acid-
ity is due to difference in aeration and mois-
ture content of the soil at different seasons.
Lipman and Waynick,! in an investigation of
the effect of climate on soil properties, report
that Maryland soil, which shows an acid reac-
tion in its original location, when transported
to Kansas or to California becomes neutral or
slightly alkaline. It is quite probable that the
better drainage and aeration of the soil when
placed under less humid conditions could ac-
count very largely for the changes in reaction.
Considering SiO, an acid-forming oxide,
practically all soils except those very high in
the basic reacting elements, have a potentially
great capacity for developing an acid reaction.
The writer believes that the constitution of
the silicates of aluminum has more to do with
injurious soil acidity than any other single
factor. The acidity of aluminum silicates
varies both with the relative proportion of
SiO, to ALO, and with the amount of com-
bined water in the silicate? The weathering
and changing of soil silicates under poorly
drained or well-drained conditions would un-
doubtedly vary the constitution of the silicates
and also vary the degree of soil acidity. It is
quite true that certain types of well-drained
sandy soils are acid. It is true also that a
number of other factors besides drainage con-
ditions affect soil acidity, but it is probable
that the most acid soils are formed in poorly
drained areas. S. D. Conner

tween these two systems of elements, which
is Just what it is desired to prove. A study
of the compilations made by Farrington, by
Merrill, and by other workers of analyses of
meteorites, has given some very interesting
results.
The results show that in either the stone
or the tron meteorites the even-numbered
elements are very much more abundant
than the odd. Thus in the iron meteorites
there are about 127 times more atoms of
even atomic number than of odd, while in
the stone meteorites the even-numbered ele-
ments are about 47 times more abundant.
If we average the 125 stone and 318 iron
meteorites given by Farrington, it is found
that the weight percentage is 98.78 for the
even and 1.22 for the odd-numbered ele-
ments, or the even-numbered elements are
about 81 times more abundant.
If we consider these same meteorites, 443
in all, and representing all of the different
classes, it is found that the first seven ele-
ments in order of abundance are iron, oxy-
gen, silicon, magnesium, calcium, nickel
and sulphur, and not only do all of these
elements have even atomic numbers, but in
addition they make up 98.6 per cent. of the
material of the meteorites.
Table IV. gives the average composition
of these meteorites. The numbers before
the symbols are the atomic numbers, and

those below give the percentages of the
elements. Jt will be noted that the even-
numbered elements are in every case more
abundant than the ADJACENT odd-numbered
elements. The helium group elements form
no chemical compounds, and are all gases,
so they could not be expected to remain in
large quantities in meteorites. For this
reason, and also because the data are not
available, the helium or zero group is
omitted from the table.
From this table it will be seen that while
high percentages, as great as 72 per cent.
in one case, are common among the even-
numbered elements, the highest percentage
for any odd-numbered element is less than
one per cent. (0.39 for aluminium).
If we now turn to the composition of the
earth, it is found that the atoms of even
atomic number are about ten times more
abundant in the surface of the earth than
those which are odd. Also, all of the five
unknown elements, eka-cesium, eka-manga-
nese 1, eka-manganese 2 (dwi-manganese),
eka-iodine and eka-neodymium, have odd
atomic numbers. It should be mentioned
in this connection, however, that there is
some doubt as to whether element 72 has
been discovered.
While the relative abundance of the ele-
ments in the lithosphere is undoubtedly
much affected by differentiation, there is
one group whose members are so closely
similar in chemical and physical proper-
ties, that they would be much less affected
in this way than any other elements. These
are the rare earths. The only difficulty in
this connection is that of making an accu-
rate estimate of the relative abundance.
In this the writer has been assisted by Pro-
fessors C. James and C. W. Balke, but any
errors in the estimate should not be attrib-
uted to them. In the table, which includes
beside the rare earths a number of elements
adjacent to them, the letter c indicates com-
mon in comparison with the adjacent ele-

sents a relatively very common element, ete.
The comparison is only a very rough one,
but it indicates that the even-numbered
elements are in general more abundant
than the odd-numbered ones which are ad-
jacent. 7

The above results may be summarized in
the statement that IN THE FORMATION OF
THE ELEMENTS MUCH MORE MATERIAL HAS
GONE INTO THE ELEMENTS OF EVEN ATOMIC
NUMBER THAN INTO THOSE WHICH ARE ODD,
either because the odd-numbered elements
are the less stable, or because some constit-
uent essential to their formation was not
sufficiently abundant, or as the result of
both causes.
It is easy to see, too, that in the evolu-
tion of the elements, the elements of low
atomic number and low atomic weight have
been formed almost exclusively, and this
indicates either that the lighter atoms are
more stable than those which are heavier,
or else that the lighter atoms were the first
to get the material, and their stability was
at least sufficient to hold it.
It is possible that the heavier atoms have
been formed in larger amounts than now
exist, and that their abundance has been
reduced by atomic disintegration. It is of
course evident that the radio-active ele-
ments are now disintegrating, but the radio-
active series of elements includes only those
of atomic number 81 (thallium) to 92
NoveMBER 9, 1917]
(uranium) ; and lead (82) is the end of the
series as now recognized. For our pur-
poses, however, we still call the atoms of
atomic numbers 1 to 29 the lighter atoms,
and from 380 to 92 the heavier atoms. The
following table indicates that when de-
fined in this way the lighter atoms are ex-
tremely more abundant. In the table the
weight percentages are given, but it is evi-
dent that if these same figures were caleu-
lated to atomic percentages they would show
even smaller values for the heavier ele-
ments. The table shows that although the
heavy atoms have been so defined as to in-
clude more than twice as many elements
as the light atoms, their total abundance
is so small as to be relatively insignificant.
The data are taken from estimates by
Clarke and by Farrington.

It is thus seen that SO FAR AS THE ABUN-
DANCE OF THE ELEMENTS IS CONCERNED, THE
SYSTEM PLAYS OUT AT ABOUT ELEMENT 30,
and it is of great interest to note that it is
just at this point that other remarkable
changes occur. For example, up to this
point nearly all of the atomic weights on
the oxygen basis are very close to whole
numbers. On the other hand the elements
with higher atomic numbers (28 to 92)
have atomic weights which are no closer
to whole numbers than if they were
wholly accidental. Also, just at this
point the atomic weights cease to be those
SCIENCE
447
predicted by the helium-hydrogen theory
of structure presented in this paper
(Table III.). This does not mean, how-
ever, that the helium-hydrogen system
fails at this point, but that the deviations
in the atomic weights for the elements of
higher number are produced by some com-
plicating factor. This would be most easily
explained on the hypothesis that isotopes
are abundant among the elements of atomic
number higher than 28. Such a hypothe-
sis should, of course, be confirmed experi-
mentally before it is given much credence.
It is quite possible, too, that radioactive dis-
integrations have proceeded downward in
the system as far as iron, and that iron is
the end of a disintegration series. If this
were true, it would explain the great abun-
dance of iron in the meteorites. In what-
ever way we may average the analyses of
the materials found in meteorites or on
earth, the two most striking elements from
the standpoint of abundance are oxygen,
the most abundant of the elements of very
low atomic number (8), and iron, which
has the highest atomic number (26) of any
very abundant element.
The fact that the elements which have
heavy atoms (atomic numbers 30 to 92, or
more than two thirds of the elements) have
been formed in such minute amounts
would be very much more striking to us if
we lived on an earth with a perfectly uni-
form composition. On such an earth,
formed without any segregation, it is prob-
able that almost none of these elements
would have been discovered. Quite cer-
tainly such elements as gold, silver, iodine
and arsenic would not be known, and
copper, lead, zine and tin, if known at all,
would be in the form of extremely small
specimens.
In this connection it may be remembered
that the earth has the highest density of
any of the planets. The data given in
Table V. show that in the meteorites, which
448
vary in density from about 2.5 for the
lightest stone, to more than eight for the
heaviest iron meteorites, the increase in
density is not brought about by an increase
in the abundance of what have been de-
fined as the heavy atoms, but only by a
shift in the relative abundance of the light
atoms. Thus in the less dense stone
meteorites the average atomic percentage
of oxygen, atomic weight 16, is 54.7 per
cent., while that of iron, atomic weight
55.84, is 10.6 per cent. In the more dense
iron meteorites, on the other hand, the per-
centage of oxygen is practically negligible,
while that of iron has risen to 90.6 per
cent.* A study of the densities of the ele-

be related to this property. In fact the
only apparent relation is to the atomic
number, which indicates that the abun-
dance relations are the result of evolution,
that is of the factors involved in the forma-
tion and disintegration of the atoms.

Note: Since the presentation of the
above paper it has been pointed out by
Norris F. Hal] that both the isotopic com-
plexity, and the number of predominant
radiation of the radio-active elements show
a sharp alternation with increasing atomic
number, and that this alternation is strictly
in accord with the general hydrogen helium
theory of atomic structure. The variation
of these properties is illustrated in Figure
4 and it will be seen that the general form
of these figures is the same as that of
Figures 2 and 3 which represent the abun-
dance of the elements.
THE CARE OF WOUNDED SOLDIERS
Many matters of importance touching upon
American cooperative effort and activity along
medical and surgical lines were developed
during the past week in Chicago, when the
general medical board and the State activi-
ties committee of the medical section of the
Council of National Defense held stated
meetings in conjunction with the annual
meeting of the Clinical Congress of Surgeons
of North America. Secretary of the Navy
Daniels discussed the activities of the Navy
directed toward the moral and _ intellectual
welfare of the naval personnel, and Surgeon
Generals Gorgas, Braisted, and Blue spoke
for the Army, Navy, and Public Health Servy-
ice, outlining the medical work in these re-
spective branches.
Surgeon General Gorgas at a meeting of
the general medical board, which preceded
the clinical congress, outlined the efforts now
being directed toward meeting medical needs
on the fields of battle, at home, and also in

10 per cent. of the wounded are permanently
disabled.
On their return home the American soldiers
will receive not only adequate medical treat-
ment but will also be afforded the extra facili-
ties of special hospitals built with the idea
in view of rehabilitating physically and re-
educating industrially our incapacitated sol-
diers. It is also contemplated to devote spe-
cial hospitals in France to the treatment of
special diseases, such, for example, as tuber-
culosis or injuries of the head, brain, eyes,
ears, or face.
General Gorgas announced the fundamental
policy of adhering to the Manual of 1914,
which provides that the military hospitals
shall consist of three general divisions, medi-
cine, surgery, and laboratories. Under this
type of organization the specialties will have
full scope and yet come under adequate medi-
cal or surgical control and direction.
The Clinical Congress of Surgeons of
North America is an organization founded
seven years ago by Dr. Franklin H. Martin,
of the advisory commission of the Council of
National Defense, of Chicago. Surgical
demonstrations were held at 25 important
Chicago hospitals and programs were arranged
almost exclusively along medico-military lines.
France was represented by Colonel C.
Dercle and England by Colonel T. H. Good-
win, R. A. M. C. Sir Berkeley Moynihan
presented the activities of the British Army
and Major George W. Crile, M. R. C., detailed
the American medical activities in France.
After Colonels E. L. Munson and F. F.
Russell had outlined the work of the Sur-
geon General’s office in organizing the medical
officers’ training camps and the various mili-
tary laboratories, Sir Berkeley Moynihan con-
tributed an exposition of wound treatment in
the British Army. He explained in detail the
search for satisfactory antiseptic drugs and
SCIENCE

ventured the novel axiom that wounds did
best when merely carefully cleaned, put at
rest, and kept free from contact with any drug
or antiseptic. His address attracted much at-
tention because it was the first authoritative
denial of the universal efficacy of the now
famous Carrel-Dakin technique of wound
treatment.
Major G. W. Crile, in discussing the ad-
dress of Sir Berkeley, corroborated all that
he said. Short addresses were made by Drs.
Edward Martin, E. H. Dunham, and W. E.
Lee, all of Philadelphia. By means of a
moving-picture demonstration and the detail-
ing of experimental and clinical data, they
showed how much could be done for clean
wound healing by the new antiseptic, Dichlor-
amine-T, which is being investigated under
instructions from the Surgeon General’s office.
Dr. William O’Neill Sherman, who presented
evidence of the efficacy of the Dakin-Carrel
method of wound treatment, closed the Tues-
day evening program.
In addition to the usual committee reports,
the meeting of the general medical board was
livened by two instructive reports from Sir
Berkeley and Major Crile. Sir Berkeley
showed the remarkable efficiency developed by
the Medical Corps of the British forces, and
this despite the fact that 96 per cent. of the
doctors were civilian physicians at the out-
break of the war. This efficiency is attribut-
able, among other things, to the two important
factors of “surgical teamwork” and surgical
consultants. The principle of surgical team-
work was learned in the United States, said
Sir Berkeley, and the principle of consultants
(these consultants are picked from the leading
surgical minds of Britain) was evolved from
the necessity of having some one authoritative
group to direct and correlate medical activi-
ties consecutively from the field dressing sta-
tions back to the base hospital.
Major Crile outlined this plan for the so-
called clinical sector, which in brief is made
up of a team of men, selected preferably from
a university or hospital where they have preyi-
ously worked in unison, and now distributed
among the dressing, field, evacuation, and
450
base hospitals of a given sector at the front.
The object of such a unit is to secure at all
times uniformity and continuity of oversight
in the treatment of the wounded from the
time of the first field dressing to the comple-
tion of convalescence.
At the meetings of the States activities
committee resolutions were introduced and
acted upon in regard to the universal training
of young men above,19 for a period of six
months, for the rehabilitation of rejected
physically defective conscripts, and for the
prophylaxis, control, and treatment of ve-
nereal disease.
DEATHS AMONG ORNITHOLOGISTS
Tue Auk publishes obituary notices of sev-
eral ornithologists who have died recently from
which we take the following facts:
Dr. Emil August Goeldi died suddenly at
Bern, Switzerland, July 5, 1917, in the fifty-
eighth year of his age. He was born at Ennet-
biihl, Canton of St. Gall, Switzerland, August
98, 1859. He studied at the Zoological Station
at Naples and was assistant of Professor
Ernst Haeckel at the Zoological Institute at
Jena. In 1884 he went to Brazil and became
associated with the museum in Rio de Janeiro.
After the fall of the Emperor Dom Pedro IL,
in 1889, he retired from this position and lived
for four years in the state of Rio de Janeiro.
About 1894 he founded the museum in Para,
now known as the Museu Goeldi. This insti-
tution which comprised not only a museum but
also a zoological garden and a botanical gar-
den was taken over by the state a few years
later and Goeldi then became honorary di-
rector. In 1905, after twenty years of life in
the tropics, he returned to Switzerland and
took up his residence in Bern where, since
1908, he has been professor of zoology in the
Cantonal University. He visited the United
States in August, 1907, at the time of the
meeting of the Seventh International Congress
of Zoology in Boston. Dr. Goeldi has pub-
lished a number of papers in English, German
and Portuguese on various branches of zool-
ogy, but chiefly on mammals, birds and fishes.

Alfred John North died of heart failure at
Sydney, Australia, May 6, 1917, only five
months after the death of his former chief and
associate, Dr. E. P. Ramsay. He was born in
North Melbourne, Australia, June 11, 1855,
and was educated in the public and grammar
schools of Melbourne. Later he worked at the
jeweler’s trade for some years. At an early
age he developed an interest in ornithology
which was stimulated by visits to the National
Museum at Melbourne and by the officers of
this institution, Sir Frederick McCoy the di-
rector, and John Leadbeater in charge of
ornithology. In 1878 he corresponded with
Ramsay and eight years later went to Sidney
to arrange the Ramsay collection of birds and
the collection of eggs of the Australian Mu-
seum. After spending several months at this
task he was asked to prepare the “ Descriptive
Catalogue of the Nests and Eggs of Birds
found Breeding in Australia and Tasmania”
which was published in 1889. About this time
he was appointed an assistant to the curator,
Dr. Ramsay, and in 1891 was made ornitholo-
gist of the museum, a position which he re-
tained until his death. He has published
many papers on the birds of Australia.
Rey. William Rogers Lord died in Dover,
Mass., February 2, 1916, in the sixty-ninth
year of his age. He was born in Boston, Mass.,
May 6, 1847. He graduated from Amherst
College with the degree of A.B., in 1875 and
from the Union Theological Seminary, in New
York, in 1878, and had held pastorates in the
East and in the West.
Mr. Lord was deeply interested in birds
and especially in popularizing bird study and
bird protection.
Dr. Bert Heald Bailey died at Cedar Rap-
ids, Iowa, June 22, 1917. He was born at
Farley, Iowa, May 2, 1875. Dr. Bailey grad-
uated from Coe College in 1897 and received
his master’s degree from the same institution
in 1900. In 1900 he also completed his course
and received an M.D. degree from Rush Med-
ical College, Chicago. In September, 1900, he
became professor of zoology and curator of
the Museum of Coe College, a position which
he held at the time of his death.
NoveMBeER 9, 1917]
He published a small volume entitled “200
Wild Birds of Iowa’’ in 1906, and was the au-
thor of numerous short papers and notes on
mammals and birds which appeared from time
to time in the Proceedings of the Iowa Acad-
of Science and in The Auk. In addition,
many valuable notes contributed by him ap-
pear in Anderson’s “ Birds of Iowa.”
Francis Windle died at his home in West
Chester, Pa., on February 24, 1917, in his sev-
enty-second year. Mr. Windle was born in
West Marlboro, Chester county, Pa. He lived
most of his life in West Chester, having re-
ceived his education in the schools of his na-
tive county and at the University of Michigan,
at which latter place he took his law course.
Owing to poor health Mr. Windle found it
necessary to give up the practise of law and
seek outdoor employment. He secured a posi-
tion with one of the extensive nurseries at West
Chester. Here his wide knowledge of botany
acquired during his frequent outing trips,
which constituted his chief recreation for
years, proved a valuable asset. During his
recreational activities his time was about
equally divided between his study and observa-
tion of plants and birds, with the result that he
became skilled in both botany and field orni-
thology.
For several years Mr. Windle taught biology
at Darlington Seminary, West Chester, and
also did some teaching at the State Normal
School in the same place.
For about eleven years prior to his death
he was connected with the Bureau of Zoology,
Department of Agriculture of Pennsylvania,
with headquarters at Harrisburg. He became
assistant orchard inspector for the eastern end
of Pennsylvania, and while acting in this ca-
pacity was made a member of the Chestnut
Blight Commission, and later of the White
Pine Blister Rust Commission. The duties of
these positions took him all over the eastern
end of the state and kept him out of doors
where he could indulge his passion for botany
and ornithology. He was a member of the
Philadelphia Botanical Club and of the Dela-
ware Valley Ornithological Club and kept con-
stantly in touch with men in these fields.

SCIENTIFIC EVENTS
WAR SERVICE FOR CHEMISTS!
France and England freely acknowledge
that they greatly decreased their efficiency by
sending their scientific men to the trenches.
Although they have since withdrawn most of
those still alive and are now using them in
special service, the dearth of technically
trained men has been and is severely felt.
Secretary of War Baker, aware of this fact,
is carrying out the full spirit of the selective
draft, and specially trained men, so far as
needed, are being assigned to the war service
which they are trained to render.
More than others among scientific men,
trained chemists have been needed for war pur-
poses by both the Army and the Navy.
Fortunately, the American Chemical So-
ciety and the Bureau of Mines, acting coopera-
tively, foreseeing this need, took first a census
of American chemists and later compiled from
all data available a list of those enlisted. From
this list of chemists actually in the Army and
the Navy a large number have been selected
for special fitness and have been already as-
signed. Many more, undoubtedly, will he so
assigned, and if the present demand keeps up,
it may later be necessary to ask for special en-
listment for chemical work. That time has not
yet arrived.
At present any chemist not required by law
to enter chemical war service who enters vol-
untarily keeps one chemist in the ranks and
deprives the chemical industries of his own
service as well. A number of chemists have
been commissioned, but these are picked men
of special attainments and specific experience.
The majority will serve as privates or non-
commissioned officers until such time as they
are found to deserve promotion.
Don’t ask to be assigned to chemical work
until you are actually in the camp. Camp as-
signment must be made before your name will
be submitted to the War Department.
Don’t send in your name, even for considera-
tion for such service, if exemption is to be

ing Chemistry.

asked for or while exemption claims are pend-
ing. It leads to endless confusion.
Don’t try to deprive another chemist actu-
ally in the Army of his opportunity to render
chemical service by yourself seeking such serv-
ice, until called. The industries which supply
the Army and Navy with the sinews of war
need trained chemists and are being seriously
handicapped by the depletion of their chemical
personnel.
| Don’t write to anyone in Washington to aid
you in a claim for exemption. Even if they
wished to do so, they are quite properly power-
less for the law delegates exemption to the Lo-
eal and District Boards.
Do send me your name, address, military
and camp assignment when actually sworn in
(not before). If you have not already filed de-
tails of your age, training and experience, send
this also at the same time.

lution thanking the Drs. Mayo for their gift
establishing the Mayo Foundation for medical
investigation and research:
Whereas, Dr. William J. Mayo and Dr. Chas.
H. Mayo, of Rochester, Minnesota, have given the
sum of $1,650,344.79 to the University of Minne-

unanimous action of the board of regents,
Therefore, be it Resolved, That the board of re-
gents records its profound sense of gratitude to the
donors. The gift is unique in the annals of Amer-
ican education. It represents the lofty purposes of
two of the most distinguished citizens of our com-
monwealth. They believe that this money has
come from the people and that it should be returned
to the people. It has been the sole aim of the
donors to provide a fund which would be of perma-
nent benefit to the state of Minnesota and to man-
kind as a whole. They have wisely and appropri-

ately provided that the income of the fund shall
be used for medical education and research.
American universities should be encouraged in the
prosecution of an educational policy which aims to
develop investigators and scientists of the first
rank. One clear function of a true university is
to make actual contributions to various fields of
knowledge. This new foundation, therefore, re-
lates itself very intimately to the realization of our
highest educational aims. Both for the gift itself
and for the genuine impetus which it will impart to
scholarly investigation in this university, we desire
to convey to the donors our sincere appreciation.
THE CONNAUGHT LABORATORIES OF THE
UNIVERSITY OF. TORONTO
Tue Connaught Laboratories of the Univer-
sity of Toronto, and a farm of fifty acres,
were formally presented by Colonel Albert
Gooderham, to the University of Toronto and
at the same time officially opened by the Goy-
ernor General, the Duke of Devonshire, on Oc-
tober 25. The value of the gift is about sev-
enty-five thousand dollars. The laboratories
are to be used for the purpose of research in
preventive medicine and for the production of
serums and vaccines. Sir William Hearst, the
premier of Ontario, at the opening, announced
that a grant of seventy-five thousand dollars
would be authorized at the next session of the
legislature, to establish a research foundation
in preventive medicine. The income from this
and also from an additional twenty-five thou-
sand dollars, will be used for research only,
the laboratories being self-supporting. This is
the first endowment of research in preventive
medicine in Canada. In connection with the
official opening of these laboratories, a lecture
was delivered in Convocation Hall, on the
same evening by Dr. Simon Flexner, director
of the Rockefeller Institute for Medical Re-
search, on the “ War activities of the Rocke-
feller Institute.” A distinguished audience,
including the Governor General and the Lieu-
tenant Governor, attended this most interest-
ing and able lecture.

Experimental Therapeutics, and the American
Society for Experimental Pathology. Many
members of these societies are engaged in

tary hopes that the scientific program will
strongly reflect this present activity and that
the meeting will be one of unusual interest
and enthusiasm. The members of the socie-
ties are urged to make vigorous efforts to at-
tend and to contribute to the program. The
fact that the meetings of the American Asso-
ciation of Anatomists and the American Zo-
ological Society occur at the same time and
place lends the strong appeal of mutual and
cooperative interest which every member of
the federation will find it difficult to resist.

sire on the part of members of the American
Society of Naturalists to contribute papers,
the Program Committee will this year receive
titles for a program to begin on Wednesday
morning, January 2. It is desired that the
papers be short and it should be remembered
that the interests of the Naturalists are pri-
marily on problems of organic evolution. The
papers on this program will in general be ar-
ranged in order of the receipt of the titles, ex-
cept that papers on similar subjects may be
grouped. Titles with estimated length of de-
livery and statement of lantern or chart re-
quirements must be in the hands of the secre-
tary by December 1.
Nominations for membership must be sent
to the Secretary not later than December 1 in
order that the Executive Committee may give
them due consideration before the meeting.
Blank forms for nominations may be obtained
from the secretary.
’ Headquarters of the Naturalists will be at

DISCUSSION AND CORRESPONDENCE
THE “AGE AND AREA” HYPOTHESIS OF
WILLIS
Tuer “Age and Area” hypothesis of Willis,
recently discussed and endorsed by Professor
De Vries in Scrence,! states that “the area
occupied by any given species (of plants)
at any given time in any given country
in which there occur no well-marked bar-
riers depends upon the age of that species
in that country.” The older the species is,
in other words, the wider is its range. If con-
firmed, this hypothesis would be of the great-
est scientific importance, for not only would
it discredit the efficacy of natural selection—
the point chiefly emphasized by its author
and Professor De Vries—but, by enabling us
to identify with certainty the most widespread
types as the most ancient ones, in any given
region or in the world as a whole, it would
also clear up a host of vexed questions in
plant geography and plant phylogeny. Certain
objections to the hypothesis appear to be so
great, however, as to cast doubt upon its
universal applicability; and a careful study
of the floras of Ceylon and New Zealand, the
regions with which Professor Willis has
chiefly worked, serves to emphasize the com-
plexity of the whole problem involved.
Factors other than age evidently share in
determining the area occupied by a species.
1De Vries, H., ‘‘The distribution of endemic
species in New Zealand,’’ Scrence, N. S., Vol.
XLV., No. 1173, pp. 641-642, June 22, 1917.
458
Barriers of various sorts certainly do exist
almost everywhere and effectively limit the
extent to which a species may be dispersed.
We have reason to believe that many types
are as widespread as they can ever be and that
no increase in age, other factors remaining
constant, will widen their ranges. In fact,
evidence from fossils shows that certain spe-
cies and genera occupy to-day smaller areas
than they formerly did.
Factors inherent in the plant itself are also
bound to influence the extent of its distribu-
tion. Types which are hardy and able to
thrive under a wide range of conditions will
obviously spread farther and faster that those
which are sensitive or specialized. The growth
habit of a plant, too, seems to be very im-
portant in determining distribution, trees usu-
ally occupying small ranges, shrubs wider
ones and herbs the widest of all. This may
be observed in almost any flora and is very
noticeable in those of Ceylon and New Zea-
land, where the endemic species, necessarily
of limited dispersal, are predominantly trees
and shrubs; the non-endemic, widespread ones,
predominantly herbs. The data as to rela-
tive commonness of species in Ceylon given
in Trimen’s “Flora,” the authority used by
Professor Willis, also show clearly that the
herbs are much commoner and more widely
dispersed than are the woody plants.
The theory that the most widespread types
are the oldest meets with further difficulties
from some of its implications. The fact
which we have just mentioned, that species
of herbs tend universally to have much wider
ranges than those of shrubs or trees, a cir-
cumstance long ago noted and emphasized by
De Candolle, must mean, if we follow Pro-
fessor Willis, that the herbaceous element in
the angiospermous vegetation of the globe is
more ancient than the woody element.
Against this conclusion there are serious ob-
jections, and it is at present maintained by
few botanists or geologists. In its interpre-
tation of endemic types the hypothesis is also
open to objection, since it regards endemic
species and genera in all cases as of recent
origin, the newest element in their respective
SCIENCE
[N. S. Von. XLVI. No. 1193
floras. There is much evidence, however,
from taxonomy and paleobotany, that in many
eases endemics are relicts of types once much
more widely spread which have disappeared
from all regions save one. Such endemics
are evidently ancient rather than recently
acquired members of a flora.
This point involves the necessary corollary
to his hypothesis which Professor Willis
brings forward when he states? that the
“ dying out ” of a species is a rather rare event,
usually requiring some profound geological or
climatic change. This belief in the essential
permanency of types necessarily leads Pro-
fessor Willis to the view that species or genera
which are isolated taxonomically and without
near relatives have become so not through the
extinction of intermediate and connecting
forms, but by a single step, a view demanding
belief in the frequency and permanence of wide
mutations. If we look again at the fossil
record, however, we see such an overwhelming
array of extinct types that it is hard to attrib-
ute their extermination in every case to a
cataclysmic disturbance. This difficulty in-
creases when we examine the flora of any such
isolated region as Ceylon or New Zealand. If
Professor Willis’s hypothesis is correct, the
original invaders of each of these islands—its
oldest plant inhabitants—should now be the
most widespread and common members of its
flora, in contrast to the endemic forms which
have sprung from them and are thus more rare
and local. If we look at the flora of Ceylon,
however, we find that there are no less than 63 ©
genera of dicotyledons alone, 8 per cent. of the
whole, which, though not endemic in Ceylon,
are represented only by endemic species. In
New Zealand 90 non-endemic genera of dicoty-
ledons, or 48 per cent. of the whole, are simi-
larly represented only by endemic species. In
these cases, where in each genus is the parent
species or group of species, the original in-
vader, which has supposedly given rise to all
these endemic forms and which should now be
more common than any of them? It certainly
2Willis, J. C., ‘‘The evolution of species in
Ceylon, with reference to the dying out of spe-
cies,’’? Annals of Botany, Vol. XXX., 1916, p. 1.
NoveMBER 9, 1917]
has died out in some way, since it no longer
exists in the island.
A further objection to the hypothesis lies in
its particular application to the flora of New
Zealand. On the basis of the soundings, Pro-
fessor Willis believes that the land bridge over
which came the original plant population of
the islands entered at about the center of the
chain. He presumably refers to the strip of
shoal water running northwesterly from New
Zealand toward Australia, on which stands
Lord Howe Island. On the assumption that
all the original invaders entered at this central
point and spread north and south, and that in
doing so they followed the rule of “age and
area,’ Professor Willis makes and verifies a
series of predictions as to the disposition of
the flora to-day. His whole argument hinges
on the existence of an original central point of
entry and dispersal. It neglects entirely the
evidence that a large and characteristic ele-
ment of the New Zealand flora entered the is-
lands not from Australasia on the west, but
from the antarctic regions to the south.
Hooker, Wallace and Cheeseman, the foremost
authorities on antarctic floras, state their be-
lief that, even if there was never a complete
land bridge from the southern extremity of
New Zealand to the antarctic continent, there
was at least a considerable southward exten-
sion of New Zealand at one time (for which
there is also evidence on the ocean bottom)
over which the “antarctic types” came north
and entered it. If the southern tip of New
Zealand was thus also a center of entrance and
dispersal for a large floral element, Professor
Willis’s observations are far from supporting
his hypothesis. He notes particularly the
scarcity of endemic species at both the north
and south extremities of the islands, and
points to this fact as convincing confirmation
of his views, since (assuming a single central
point of dispersal) the extremities would be
populated last and would have produced as yet
but few endemics. But assuming a second
point of entry, at the southern extremity of the
islands, we should expect to find there to-day,
if the “ age and area” hypothesis is true, a de-
cided bunching of endemic species. Either the
SCIENCE
459
hypothesis is incorrect, or the commonly ac-
cepted theory as to the dispersal of the ant-
arctic floras is erroneous.
Against Professor Willis’s hypothesis are
therefore to be urged (1) that it disregards im-
portant factors other than age which deter-
mine area of dispersal; (2) that the conclu-
sions which it necessarily implies as to the an-
tiquity of certain plant types are opposed by a
preponderance of evidence; (3) that, contrary
to its expressed assumption, many species are
becoming rarer and are “ dying out”; and (4)
that it fails to explain the distribution of the
New Zealand flora.
There are doubtless a large number of spe-
cies which are still extending their ranges and
for which Professor Willis’s hypothesis holds
good. Many persons will also sympathize with
his chief contention, that natural selection
ean not fully explain the origin of endemic
species and genera; and a few will share
his belief in the frequency and importance of
very wide mutations. The problems involved
in the origin, dispersal and extinction of spe-
cies, however, are evidently far too complex to
be covered by any single inclusive hypothesis
like that of “age and area.”

ERASMUS DARWIN AND BENJAMIN FRANKLIN
To THE Epiror oF Science: Referring to the
Notes on Erasmus Darwin and Benjamin
Franklin in Science of September 21, last, on
page 291 near the bottom of Column 1 is the
remark that
Even as far back as 1772 some one was puzzling
over the idea of making a phonograph.
He quotes Dr. Darwin as saying:
I have heard of somebody that attempted to
make a speaking machine, pray was there any
truth in such reports?
The “speaking machine” referred to was
not a phonograph for reproducing speech, but
a machine which could talk of itself. There
was an effort to make such a machine, which
the writer of the article quoted seems not to
have heard of. This effort was continued
460
down to the time of the invention of the
phonograph, and somewhat beyond that time.
One Joseph Faber began to work on an idea
of this sort in 1815, and in 1841 had the ma-
chine so far finished that it was exhibited to the
king of Bavaria, as stated in an article from the
London Times of February 12, 1880, which is
now lying before me. This machine was ex-
hibited in America in the seventies and eighties
and I heard it talk and ask and answer ques-
tions put by the audience. Its speech was very
mechanical, without inflection or emphasis.
It was worked by an attendant with a key-
board and bellows, An ivory reed whose pitch
could be varied formed the vocal chords. The
eavity of the mouth could be changed in shape
and size by the keys of the keyboard. A
tongue and lips of rubber formed the conson-
ants. A windmill in the throat rolled the R’s
and a tube was attached to the nose when it
spoke French! It could also speak German
and English. It is not probable that any one
had thought of a phonograph in the sense in
which we use the term as early as 1772.
Knowledge of electricity was not sufficiently
advanced at that time.

QUOTATIONS
THE PHYSIQUE OF RECRUITS
In the summer of 1916 the Board of Scien-
tific Studies was established under the egis of
the Royal Society to serve as a means of plac-
ing knowledge in the possession of scientific
and technical societies at the disposal of gov-
ernment departments. At the first general
meeting of this board in July, 1916, the
urgency of a physical survey of the nation, to
discover whether or not there existed definite
evidence of physical deterioration, was dis-
cussed. Emphasis was laid by various speakers
on the fact that an Interdepartmental Com-
mittee had reported in 1904 that such a survey
was necessary. Nothing, however, had been
done. The mobilization of a national army
had provided an opportunity, as well as a need,
for such a survey.
The Board of Scientific Studies requested
the Royal Anthropological Institute to report
SCIENCE
[N. S. Von. XLVI. No. 1193
on the desirability and possibility of such a
survey. The institute having reported that
such a survey was both desirable and possible,
the board formed an Anthropological Survey
Sub-committee to consider the manner in
which such an investigation could best be car-
ried out. This sub-committee has not yet re-
ported to the Board of Scientific Studies, but
we understand that it is seeking for the means
of carrying out such a survey through the gov-
ernment departments which have directly to
do with the health and physique of the nation:
the Recruiting Authority—now the Ministry
of National Service—the Local Government
Board and the Board of Education. Repre-
sentatives of these departments have joined
the Anthropological Survey Sub-committee,
and it is hoped that a practical scheme may be
formulated at an early date.
Meanwhile American anthropologists have
stolen a march on their British colleagues.
When the United States entered the war the
National Research Council was at once ere-
ated to serve the same purpose as our Board
of Scientific Studies. Its Anthropological
Committee, formed to advise in the selection,
standardization and examination of recruits,
has already issued its report and recommenda-
tions. It proposes that six of the sixteen great
concentration camps should be selected for an
anthropological survey—two in the Eastern,
two in the Middle, and two in the Western
States—and that special men who had been
trained to use exactly the same anthropo-
metrical methods at the National Museum at
Washington, should be dispatched to carry out
a survey of the men in the selected camps.
The points for investigation have been reduced
to a minimum, namely, standing and sitting
heights, three dimensions of the head, two of
the face, two of the chest, with precise records
of the color of skin, eyes and hair. The statis-
tical staff of the Prudential Insurance Com-
pany of America has undertaken to deal with
the data collected, while the Smithsonian In-
stitution will facilitate the publication of re-
sults.
Although the intentions of the British com-
mittee are more wide-reaching and aim at as-
November 9, 1917]
certaining the condition of all elements in the
population, it is to be hoped that the observa-
tions taken in Britain and America will be
capable of direct comparison—for, beyond
doubt, the bulk of the population of the United
States has a British ancestry.

Mental Conflicts and Misconduct. By Wit-
LIAM Hrany. Boston, Little, Brown & Com-
pany, 1917. Pp. 330.
Like earlier studies from the psychopathic
institute attached to the Chicago Juvenile
Court, this work emphasizes the need of
painstaking inquiry into the experience and
inner life.of the individual delinquent, if the
treatment given him is to be in any sense
remedial. The present book illustrates the
author’s method of “ mental analysis,” a proc-
ess somewhat akin to the “psychoanalysis”
of Freud, though not making the same pre-
tensions to penetrate to the very depths of
the individual’s make-up, and not operating
with dreams, symbols or association tests,
but by a straightforward conversational ap-
proach, in which the subject is sympatheti-
eally asked to tell “if anything is worrying
him.” This line of approach is especially in-
dicated when the subject shows signs of an
“inner urge” towards misdoing, without de-
riving any material benefit, but only painful
consequences, from his misdoing. In such
cases, there is reason to suspect a “mental
conflict,” which may be discovered by the
analysis and then cleared up by proper hand-
ling, with the happy result that the misccn-
duct ceases.
The mental conflict discovered by analysis
is often of the following stamp. A young
child, previously a good child, and often of
good intelligence and from a good home, is
incited by some bad boy or girl or older
person to sex practices, and very often at the
same time to stealing or truancy. The child
rejects the sex practices, though often obsessed
by the thought of them or by the bad words
used in connection with them, but begins to
steal or run away from home. The author
interprets this to mean that an “inner urge,”
SCIENCE
461
primarily directed towards sex behavior but
prevented from finding an outlet there, es-
capes through the channel of stealing, etc.,
which has become accidentally associated in
the child’s mind with the sex matter. From
such causes, quite a career of delinquency
may be entered upon by children who are
fundamentally normal and healthy-minded.
As judged from a series of two thousand
juvenile recidivists, the per cent. of cases of
delinquency in which mental conflict of this
general type enters as a causative factor is
about seven—more rather than less. It is
not the “rough” type of juvenile offender
that is here in question, nor the mentally
defective. Usually the cases show good men-
tality and good social qualities. They are
not moody and “shut-in,” nor egocentric,
nor, indeed, of any peculiar mental or temp-
eramental type (unless, as is possible from the
tests given, the imagery or mental representa-
tion of these individuals is unusually active
and vivid). Heredity does not appear as an
important factor; but it is rather the social
or mental environment of the child that gen-
erates the conflict. Specially important in
this regard is the lack of confidential re-
lations between the child and his parents,
leading the child to keep his difficulties to
himself, when a frank discussion of them
with a sympathetic adult would resolve the
conflict.
The treatment appropriate to this species
of delinquents is by no means punishment—
an entirely superficial and notably unsuccess-
ful reaction—but, first of all, mental analysis
directed to discovering the genesis of the mis-
conduct, and then “reeducation,” including
the giving of suitable information and the
development of an intelligent attitude towards
the causes of conflict; further, the establish-
ment of confidential relations between the
delinquent child and an adult adviser, and
often the removal of features of the environ-
ment that suggest misconduct.
Psychologically, the author’s case-material
is of great interest, and the interpretation
given, in terms of mental conflict, is likewise
of considerable interest, though it does not
462
appear to fit all the cases equally well. To
the reviewer, at least, a rather different “‘ men-
tal mechanism” would seem to fit the case
histories better. In particular, the associa-
tion between sex behavior and such other
forms of misconduct as stealing and truancy
is perhaps not so purely accidental and ex-
traneous as the author assumes; for all of
these forms of bad conduct typify for the
child that life of ‘‘ badness” which, perhaps
because of its rebellion against authority and
restraint, makes a certain appeal even to the
“good” child. That is to say that the child
does not resort to stealing as an outlet for
dammed-up energy primarily directed towards
sex behavior, but that, being incited to “ bad-
ness” in several directions, and responding
in some measure to the incitation, he follows
the line that he is able to understand and
follow with some success, leaving aside what
he is not ripe for, though perhaps being mys-
tified and obsessed by this latter.

Telephone Apparatus. By Grorce D. SHEp-
ARDSON, Professor of Electrical Engineering,
University of Minnesota. D. Appleton &
Co. 1917. 837 pages, 115 illustrations.
Considering the marvelous rapidity of
growth of telephony and the extent to which
the telephone permeates the daily life of the
modern business man, especially in America,
where there is an average of one telephone to
each ten persons, it is surprising how little is
generally known concerning the history, con-
struction or mode of operation of that wonder-
ful device. This book presents an introduc-
tion to the development and theory of tele-
phony for the educated classes of the public in
general, and particularly for those engaged in
telephonic operation or manufacture.
The book contains sixteen chapters, relating
respectively to the following subjects: Intro-
duction, Sound, Speech sounds, Telephone re-
ceivers, Telephone-receiver
Telephone transmitters, Telephone-transmitter
investigations, Signaling devices, Design of
non-polarized signaling apparatus, Perma-
investigations,
SCIENCE
[N. S. Vou. XLVI. No. 1193
nent magnets and polarized apparatus, Design
of polarized apparatus, Electromotive forces
and currents, Principles of induction coils,
Uses of induction coils in telephony, Conden-
sers in telephony, Protective devices. The
treatment is directly descriptive, abundantly
illustrated by pictures and diagrams of the
apparatus. The mathematical analysis is
nearly all collected into the appendices at the
end of the book, so that a non-mathematical
reader can peruse all the chapters with very
few interruptions.
The book deals mainly with telephonic
apparatus, and the principles underlying its
operation. Circuit arrangements are given
relatively minor consideration, and radio-tele-
phony is not included. A good set of indexes
at the end of the volume greatly assists the
reader.
A noteworthy feature of the book is the
large number of collateral references indi-
cated in footnotes throughout the text. The
collection and collation of so much historical
and technical material represents a large
amount of labor. The insertion of this sub-
ordinate material makes the work of great
value as a reference book to telephonists and
students of telephony. Probably no other
text-book on telephony in the English lan-
guage contains such a wealth of electro-tech-
nical reference material. INQ ADS AEG

ANESTHESIA AND RESPIRATION!
THERE is much uncertainty as to the effect
of anesthetics upon respiration. Some writers
hold that anesthetics decrease respiration
while others take the opposite view.? To clear

step toward a satisfactory theory of anes-
thesia.

The writer has recently been able to develop
a method? for the measurement of minute
amounts of carbon dioxide. The application
of this method to the present problem has
yielded interesting results.
The experiments were made by measuring
the change in the hydrogen-ion concentration
of sea-water produced by the respiration of
the marine alga, Laminaria. This was con-
veniently done by the addition of a suitable
indicator (phenosulphonephthalein) to the sea-
water and comparing the color of the solution
with the colors of a series of buffer solutions
of known hydrogen-ion concentration (con-
taining the same concentration of indicator).
When the concentration of the anesthetic
was so great as to cause considerable dilution
of the sea water, concentrated sea water was
added until the mixture had the same elec-
trical conductivity as sea-water. When an
anesthetic (as formaldehyde) showed an un-
usually high acidity, the free acid was first
neutralized with sodium carbonate. This is
allowable for the purposes of the present in-
vestigation, as its only effect would be to make
the amount of CO, produced appear somewhat
less than was actually the case. By selection
of sea-water from different carboys, sea-water
could be obtained for controls that had the
same PH value as that of the sea-water con-
taining the anesthetic.
The fronds were cut up into pieces about
two inches long, the cutting being reduced to
a Minimum, since it is known that an increase
of respiration may follow injury. Prelimi-
nary experiments, in which uncut smaller
fronds were used for comparison with the cut
fronds, showed that the change in the respira-
tion due to the cutting was negligible (espe-
cially since the cut pieces were usually left
about half an hour in sea-water before being
used).
Each piece of tissue was inserted into a
Pyrex glass tube, closed by fusion at one end,
a piece of paraffined rubber tubing being at-
tached to the open end. Sea-water was then

added, the solutions being the same tempera-
ture as the bath. The temperature of the
bath was always kept at 16° C. Black-
enamelled collapsible tin tubes served to ex-
clude light from the tubes. After the sea-
water bathing the tissue had been changed
several times, a given amount of sea-water was
added to the tube and a small bubble of air
was included in order to serve as a stirrer (it
was found to be preferable to paraffined glass
beads). After the tube had been kept in the
dark at 16° C. for a definite period it was re-
moved from the bath and stirred by inverting
the tube a few times. The clamp was then
opened and the solution rapidly poured into:
an empty tube, to which the same number of
drops of indicator had been added as was
added to the buffer solutions. The solution
was then mixed with the indicator in the man-
ner just described and the color was then com-
pared with buffer solutions of a known PH
value (containing the same concentration of
indicator). The decrease in PH as observed
with a constant source of light (“ Daylight”
lamp) served to measure the amount of CO,
produced by respiration.
In order to be sure that no acid except CO,
was being given off by the plant a stream of
hydrogen was allowed to bubble through the
solution which had been made acid by respira-
tion in order to see whether it came back to
the same PH value as at the start.5 This was
the case in every instance.
Each piece of material was used for a num-
ber of periods (always of the same length) in
sea-water (which was changed at the end of
each period) until the rate of respiration had
become practically constant. Then several of
the pieces were used as controls while others
were placed in sea-water containing the an-
esthetic (the solutions were always renewed at
the end of each period).
Experiments were carried on with sea-water
containing the following substances: .1 per
cent. chloral hydrate, .1 per cent. novocain, 1

cent, or acetone 17 per cent.) a little pigment may
be extracted from the plant. In this case it may be
necessary to reject the figures for the first period
(or of the first two periods).

per cent. ether, 0.1 per cent. caffeine, ethyl
bromide (approximately saturated), 3.2 per
cent. formaldehyde, .8 per cent. formaldehyde,
.38 per cent. chloroform, .05 per cent. chloro-
form, 0.1 per cent. acetone, 0.51 per cent. ace-
tone; 17.4 per cent. acetone, 24.2 per cent.

aleohol, 2 per cent. ethyl aleohol and 1 per
cent. ethyl alcohol.
It was found that whenever the concentra-
tion of anesthetic is sufficiently strong to pro-
duce any measurable result, the initial effect
is always an increase of respiration which may
either remain approximately constant over a
large number of periods and then gradually
decline or’the increased rate of respiration
may fall very rapidly below the normal when
the concentrations of anesthetic are too great.
It is very noteworthy that in no case was
the respiration of Laminaria observed to fall
below the normal when exposed to sea-water
containing anesthetic except after prolonged
exposure to high concentrations which pro-
duced death.
SUMMARY
When Laminaria is exposed to the action
of anesthetics (in sufficient concentration to
produce any result) there is an increase in
respiration. This may be followed by a de-
crease if the reagent is sufficiently toxic. No
decrease is observed with low concentrations
which are not toxic.
These facts contradict the theory of Ver-
worn that anesthesia is a kind of asphyxia,
for his view is based upon the assumption that
anesthetics decrease respiration.

AN OUTLINE OF THE LIFE HISTORY OF THE
CLOTHES MOTH, TINEOLA BISELLIELLA
Somer four years ago the writer was asked by
Mr. Walter S. Kupper and Mr. J. R. Howlett,
of New York City, to undertake an investiga-
tion of clothes moths for the purpose of gath-
ering information which would help solve the
problem of moth-proofing ordinary woolen fab-
rics. At that time and at present, the only
SCIENCE
[N. 8. Von. XLVI. No. 1193
original information available consisted of dis-
connected observations, mainly concerned with
the case-forming clothes moth, Tinea. In con-
nection with the study which followed, hun-
dreds of pounds of fur and old woolen rags
were purchased, the moth larve painstakingly
picked out, and the rags then sold back or
thrown away. One lot of eighteen hundred
pounds of old rags was purchased at one time.
From these several thousand larve of Tineola
was picked out by boys employed for that pur-
pose, and placed on test cloths which had been
treated with various chemicals in the hope of
finding one which would prevent moth ravages.
Two trunksful of fur garments were obtained
from the Salvation Army stores. Two hun-
dred pounds of blown fur were purchased from
a firm which prepares rabbit fur for the hatter’s
trade.
The yellow clothes moth, Tineola biselliella,
was the only moth found in all this material
during a period of four years. This seems
strange, especially in view of the fact that the
rag material had been shipped to New York
from all parts of the country, the large bale of
cloth above mentioned having come from the
south and consisting of dirty cast-off clothing
from that region. About three specimens of
the spotted clothes moth, Tinea, were caught
flying about the house in the Bronx, New York
City, in which the study was at first carried
on, but the circumstances indicated that they
were adventitious, and in no way connected
with the supply of Tineola fur of which only
a few cardboard boxes were present at that
time. The conclusion would seem inevitable
that in the region of New York City, at least,
Tinea is of comparatively rare occurrence and
that the extensive damage which is done in
connection with the fur and woolen trades is
due almost entirely to the other species. Both
the black and the Buffalo carpet beetles were
found invariably in each supply of moth ma-
terial, but in comparatively small numbers.
A much larger unidentified beetle occurred in
great numbers in the supply of blown hat fur
and rabbit skins which had their source in
Australia.
Infe History—Mature moths were found
NovEMBER 9, 1917]
emerging from cocoons in the fur material first.
studied in June and July, 1913. These were
caught and placed in pairs for breeding pur-
poses in jelly tumblers which were easily cov-
ered. The females were almost invariably
larger than the males and much less active.
Breeding began usually immediately after
emergence from the cocoons. The males were
active in pursuit, fluttering and running about
the female and bringing the flexible abdomen
forward until it pointed anteriorly. During
copulation the moths rested with bodies in op-
posed directions. The abdomen of the female
was always large and distended with eggs even
before copulation.
Ege-laying began within twenty-four hours
after breeding. Single females were found to
lay from thirty to one hundred and sixty eggs,
but the latter number was very exceptional
and by only one unusually large moth. The
usual number was between forty and fifty. The
egg-laying might be completed in one day or it
might continue two or three weeks. The fe-
male died when the eggs were all laid. The
males might live and continue active and
breeding for two or three weeks. Twenty-three
days was the longest period observed. The
eggs were carefully placed among the threads
of the cloths and fastened by some glutinous
material so that they did not readily shake off.
If the cloth had a ravelled edge, the female
would generally place most of the eggs deep
among the loose threads.
To receive the eggs, small pieces of woolen
cloth were generally used. When cotton cloth
was tried experimentally, the moths did not
differentiate, but laid on cotton stocking ma-
terial and also on silk.
For incubation and brooding, Petri dishes
were used and the egg-covered cloths were
placed one in each dish. Hatching began in
seven days, the larvee emerging as millimeter-
long translucent-white active caterpillars.
These began to feed immediately and were then
eolored according to the color of the cloth
used. Experiments were tried with felts of
several colors and as a result larve could be
obtained with a median streak of red, blue,
green, et al. The dyes passed through the ali-
SCIENCE
465
mentary canal apparently unchanged, and it
was always possible to determine by the excreta
what material had been fed upon when there
were cloths of different colors.
The larve behaved differently in the matter
of case making. Some began immediately to
spin a webbing case or sometimes a passage
several times the length of the body in which
they would live for a longer or shorter length
of time. Woven into this “silk” tunnel were
usually fibers from the material from which
they were feeding. In the case of fur, the re-
sulting case would often have the appearance
of a bur with the hairs woven crossways and
forming a case sometimes much thicker than
long. On cloth, the case was made of shorter
fibers closely attached to the cloth, thus dis-
tinguishing it from the cases formed by Tinea
which are carried about. When a Yineola larva
wished to change its feeding place it would
either continue its gallery, sometimes for sev-
eral inches, or would leave it entirely and build
another when a satisfactory place was reached.
As the larve grew to mature size, the feeding
case was enlarged and changed to form the
cocoon.
Other larve seemed to spend their time
“prazing” about without ever forming more
than small patches of silk if any. No conclu-
sion was drawn as to the probable explanation
of the difference. It might be that the quieter
kind were eventually to form the female moths,
and necessarily had less energy to spend in
roaming. If this is true, it establishes another
instance of the application of Kipling’s law,
for the larvee which remained in cases do much
more damage than the roaming kind. Moth
holes usually appear as round holes, or as
dumbbell-shaped slits. The latter are made by
the feeding of a stationary larva, the straight
slit part being cut out underneath the case, the
enlarged ends being at either opening of the
The single holes are merely the feeding
places at the ends of a case without the con-
necting split. These stationary larve also use
much more cloth in order to make their
eases. Of course both types enter cases at the
end before passing into the pupa stage.
The larval stage may be completed in about
case.
466
ten weeks. It was found difficult to carry defi-
nite specific Jarve under observation in
Petri dishes through the entire period, but the
time was established by noting the appearance
of new groups of moths in the larger stock of
fur. Just what there was in the Petri-dish
method of culture to hinder the larval develop-
ment could not be determined. Some larve
grew to large size, approximating maturity,
others died in a few weeks, but none were cer-
tainly carried from the egg to the cocoon.
Ten weeks appeared to be the shortest period
in which larval growth was completed, but this
is necessarily partly an estimate.
The cocoon stage lasted at the shortest two
weeks. This was definitely established by ob-
serving the time at which larve ceased feeding,
and closed their cases, and then putting such
cases away for observation.
It is probable that all stages of the life his-
tory may under some circumstances be more
or less indefinitely lengthened. Certainly the
larval stage may. Its conclusion probably de-
pends entirely on the obtaining of a sufficient
amount of food, and may probably last several
months, as over winter for example. Winter
stops the activities of this moth only when the
temperature of the surroundings is too much
lowered. In the present investigation moths
were observed emerging from cocoons and
larve were seen feeding during all months of
the year. Breeding experiments were not at-
tempted during the winter but there seems no
reason to suppose they would not have been
successful and that egg-laying would also have
occurred.
Remedies for Moths—A summary of results
along this line may be interesting.
Remedies intended for the flying-moth stage
are worse than useless. So-called repellants
such as tobacco, cedar, did not repel or harm
the moth in any stage. The imago stage is the
most delicate of all, but it could be placed in a
small closed tumbler with burning tobacco with
no apparent injury. Cloth soaked in odorifer-
ous substances for the purpose of repelling
them was made the recipient of eggs as read-
ily as untreated cloth. As already noted, the
moth laid eggs as readily on cotton and silk as
SCIENCE
[N. S. Von. XLVI. No. 1193
on wool although neither of these was used as
food by the larve.
Any method of attack must be directed
toward the larval stage to be effective.
Camphor and napthalene in closed places kill
all stages. The egg and larve turn from whit-
ish to a yellowish brown in color; the larve
cease activity almost immediately. No gaseous
poisons were tried but undoubtedly the com-
mon ones would be effective. Kerosene and
gasoline fumes were not effective.
The main method of attack in this case was
directed toward poisoning the larve through
their food. The problem was to find some poi-
son which could be placed on cloth and serve
to kill larve feeding on it before they could
do material damage. At the same time it must
not be harmful to human beings, or if harmful
in posse, must be insoluble. If baby wants to
chew mother’s dress or its woolen blanket, it
must be able to do so with impunity. After
about four years of nearly continuous investi-
gation, during which several chemists were
cooperating, the problem was finally dropped.
Numerous compounds were used in tests but
the larve proved singularly immune. Larva
placed in Petri dishes with a piece of cloth
soaked in corrosive sublimate as well as other
common poisons, ate of the cloth as shown by
the color of their alimentary canal and the
feces, but lived on for weeks apparently unin-
jured. Some few substances were found which
did appear to have some result but not enough
to justify adopting them as the basis of a moth-
proofing process.
The problem still seems to be possible, but
the solution is not apparent. After the sub-
stance is found, there still remains the over-
coming of the objections of the tailors and
clothing manufacturers, some of whom con-
sider clothes moths among their best friends.

A CHROMOSOME DIFFERENCE CORRELATED
WITH SEX DIFFERENCES IN
SPHAZROCARPOS
THE chromosome group found in the cells
of the female gametophyte of Spherocarpos
Donnellit contains one large element which
NoveMBER 9, 1917]
considerably exceeds both in length and in
thickness any of the older chromosomes. The
chromosome group of the male gametophyte
contains no element similarly distinguished
by its size; on the other hand, the male pos-
sesses a very small chromosome which seems
not to correspond in size to any element in
the female.
The other chromosomes in the cells of either
sex have the form of slender rods; there are
noticeable differences in length between those
of each group. The bending and not infre-
quent overlapping of the ends of the chromo-
somes place difficulties in the way of an exact
determination of their number; but, subject
to modification by further study, it may be
said with reasonable assurance that the chromo-
some number for each sex is eight. As to
seven of the eight, the chromosomes of the
male seem to resemble those of thé female;
but the eighth chromosome of the female is
probably corresponding to it in the male is the
the large one already referred to, and the one
very small chromosome.
Of the two spindles formed in each spore
mother cell at the time of the homeotypic
division, one shows a large body which is some-
times plainly two-parted; no element appears
on the other spindle that approximates in size
this large chromosome. It has been reported
that in at least one species of Sphe@rocarpos
two of the spores of each tetrad develop into
male plants and the other two into females.
Observations which I have made, although
as yet in limited number, indicate that the
same rule holds for S. Donnellit. The cyto-
logical results here reported seem to show that
in consequence of the chromosome distribu-
tion in the reduction divisions two of the four
spores derived from a single mother cell re-
ceive each a large chromosome (and seven of
smaller size), and these spores develop into
female plants; and that each of the other two
spores receives a small chromosome instead of
the large one, and, on germination, gives rise
to a male plant.
The resemblance between this history and
that of the chromosomes of certain insects,
such as Lyg@us and Luschistus, which pos-
SCIENCE
467
sess a large X- and a small Y-chromosome, is
obvious. It is too early to conclude that the
particular chromosomes with respect to which
the male and female gametophytes of Sphero-
carpos differ are the bearers of definite sex-
determining factors; but it seems not unlikely
at least that the greater size and vigor of
growth of the female gametophyte are associ-
ated with the greater amount of chromatin
that its cells contain.

THE AMERICAN ASTRONOMICAL
SOCIETY
THE twenty-first meeting of the society was held
August 29 to 31 at the Dudley Observatory, Al-
bany, N. Y., about ninety members and visitors
being present. The arrangements for the meeting
were admirably carried out by the host, Professor
Benjamin Boss, acting also for the trustees of the
Dudley Observatory and the department of meri-
dian astrometry of the Carnegie Institution of
Washington. The activities included an excursion
to Saratoga Lake and a visit, at the close of the
meeting, to Vassar College and its observatory.
Various committee reports and items of business
were considered by the society, among others the
question of the daylight saving movement, and
when an informal expression of opinion was called
for, the vote stood
In favor of daylight saving..... 18
Opposed to the plan ........... 22

Another matter in the same connection, which
would affect only astronomers, was a proposal com-
ing from England that the astronomical day be-
gin at midnight instead of at noon as at present.
A test vote showed that a large majority of the
members present were opposed to the change, but
after some parliamentary procedure it was agreed
to refer the matter to a committee to make a re-
port back to the society.
Officers were elected for the ensuing year as fol-
lows:
President—Edward C. Pickering.
First Vice-president—Frank Schlesinger.
Second Vice-president—W. W. Campbell.
Secretary—Philip Fox.
Treasurer—Annie J. Cannon.

Councillors—Ernest W. Brown, Edwin B. Frost,
J. 8. Plaskett, Joel Stebbins.

ELECTROMERISM, A CASE OF CHEM-
ICAL ISOMERISM RESULTING FROM
A DIFFERENCE IN DISTRIBUTION
OF VALENCE ELECTRONS1
ReEcENT advances in our knowledge of
the structure of matter have made it pos-
sible for an organic chemist to address a
group of non-organic chemists and of
physicists upon this subject without apolo-
gizing. During a period which is not far
behind us in the past, not only the validity,
but, possibly, even the utility of employing
structure conceptions requiring atoms and
their arrangements was brought into ques-
tion; so that the organic chemist, who has
maintained an abiding faith in atoms and
a confidence in his ability to decipher some-
thing of their arrangements in molecules,
became aware of an indulgent smile when-
ever he broached this subject except in the
company of his own confréres.
With this inheritance, it is natural to ex-
pect that the organic chemist would wel-
come any discoveries which make our con-
ception of atoms and of the mechanism by
which atoms combine to form molecules
more concrete ; and that he would be among
the first to seek to apply these concepts to
special problems in his own field.
With a feeling of keen satisfaction,
therefore, we learn through the work of
Bragg that, in a diamond erystal, each car-
bon atom is surrounded by four other ear-
bon atoms placed equidistant from it.
These atoms are grouped around the cen-
tral carbon atom as the four corners of a

‘«Structure of Matter,’’ held at the meeting of the
American Association for the Advancement of
Science in New York City, December, 1916.
494
regular tetrahedron are arranged around
its center. Thus, the tetravalent character
of the carbon atom manifests itself clearly.
Furthermore, when a model of a diamond
erystal is examined, it is discovered that
the atoms appear to arrange themselves in
rings of six. These relationships suggest
at once well known fundamental theories
of the organic chemist.
Through the writings of J. J. Thomson,”
Stark,? Abege* and many others, the convic-
tion has been reached, that the forces which
hold the atoms together, commonly called
chemical affinity, are chiefly, if not wholly,
electrical in character. The impetus to this
interpretation has come from the discov-
ery that electricity itself possesses an
atomic structure, and that our material
atoms appear to be composed of units of
positive and negative electrical atoms
nicely balanced in the neutral atom. As
Carl Barus says :°
Not only has energy possessed herself of in-
ertia, but with ever stronger insistence she is
usurping the atomic structure once believed to be
among the very insignia of matter. Contempo-
raneously matter, itself, the massive, the indestruct-
ible, endowed by Lavoisier with a sort of physical
immortality, recedes ever more into the back-
ground among the shades of velocity and accele-
ration.
Electrochemical theories have not been
lacking in the development of chemistry.
For many years the electrochemical theory
of Berzelius was ‘a guide in the interpreta-
tion of chemical phenomena. There is, per-
haps, no greater tragedy recorded in the
annals of science during the past one hun-
dred years than that which overtook Ber-
zelius at the close of his active career as

leader of chemical thought. We of to-day
know best why this theory failed, and why
we are now busily engaged in formulating
a new electrochemical theory, as well as a
new electrophysical theory. In fact, J.
Stark in his recent work, ‘‘Die Hlektrizitat
im chemischen Atom,’’ gives a eulogy of
Berzelius, and points out the many strik-
ing qualitative resemblances which the
theory of Berzelius bears to his own.
The special purpose of my remarks to-
day precludes any detailed discussion of
the various theories concerning the struc-
ture of the atom. This phase of the subject
has already been presented in the morning
meeting of this symposium. It may be
said that all theories agree upon a positive
core or nucleus associated with negative
electrons, the atoms of negative electricity.
Thomson presents hypotheses concerning
the possible arrangements within the atom,
while Stark limits his treatment chiefly to
the surface layer. The surface layer, he
says, contains an excess of positive electric-
ity. In the neutral atom one or more elec-
trons, called valence electrons, are held
close to the surface of the atom by this posi-
tive charge. Compounds are formed, when
the lines of force from one or more of these
valence electrons reach out and end on the
positive areas of other atoms. In the case
of strongly polar compounds, an electron
is almost wholly drawn over to the atom
which it then holds combined.
Lewis® classifies compounds into polar
and non-polar, but in a footnote remarks:
It must not be assumed that any one compound
corresponds wholly, and at all times, to any one
type.
He distinguishes between valence num-
ber and polar number. Valence number he
defines as the number of positions, or re-
gions, or points (bond termini) on the
6G. N. Lewis, J. Am. Chem. Soc., 38, 762
(1916).
NovEMBER 23, 1917]
atom at which attachment to correspond-
ing points on other atoms may occur.
Polar number is the number of negative
electrons which an atom has lost (in an
algebraic sense).
The evidence of, perhaps, indeed, the cause of the
mobility of polar compounds is the freedom of one
especially important atom, the atom of electricity,
or the electron, to move from one position to
another.
From a study of the reactions of chem-
ical compounds, and in particular of or-
ganic compounds, it seems doubtful whether
the classification into polar and non-polar
based upon physical values, such as the
dielectric constants’ of compounds in the
gaseous state, is of any more significance
than the terms electrolyte and nonelectro-
lyte were to the older supporters of the
theory of Arrhenius. In time, it came to
be known that it was no easy matter to
draw the dividing line between these two
classes, and that one class seemed to merge
imperceptibly into the other. So, with polar
and non-polar compounds, it seems theo-
retically probable that there is no per-
fectly non-polar compound, unless it be a
molecule composed of two like univalent
atoms, such as hydrogen; and that other
7 Stark (‘‘ Die Elektrizitiit im Chemischen Atom,’’
p- 29) says: ‘‘Between the properties ‘dielectric’
and ‘conducting’ there is a connection. In a di-
electric medium, since there are positive and neg-
ative ‘Quanten’ bound to one another, it follows
that the medium may become conducting when,
through proper application of energy from without,
the ‘Quanten’ pairs become partially dissociated,
or ionized; that is, into freely moving positive and
negative ‘Quanten.’ Conversely, the ions of a
conducting medium by mutual union to form
‘Quanten’ pairs may make the medium dielectric;
and in general a material medium is at the same
time dielectric and conducting, so that by as-
signing a dielectric constant and a specific con-
ductivity, the medium is characterized for a finite
electric field and a finite electrical current.’’
8 Bohr concludes that the hydrogen molecule
consists of two hydrogen nuclei (at a distance
apart of 0.60 < 10-8 em.), and two electrons which
SCIENCE |
495
compounds are polar in varying degrees,
depending upon the mutual attractions be-
tween valence electrons and the positive
surfaces or cores of the atoms combined,
and upon the distances to which these elec-
trons, in forming such compounds, are de-
flected from their normal positions rela-
tive to the positive areas of the uncombined
atoms themselves.
Even before the electron theory had been
proposed, an application of the theory of
ion formation and charges upon ions led
to ihe recognition of polar characteristics
in compounds not known to be ionogens.
In a study of chloroamines, RNHCI and
R,NCI, Seliwanow® observed that, during
hydrolyses, the chlorine in these compounds
was replaced by hydrogen; and that they
interacted with hydrogen iodide with the
liberation of two equivalents of iodine for
each equivalent of combined chlorine,
R.NC1+ 2 HI=R,NH + HCl+ L..
Usually, during hydrolysis, combined
chlorine in organic compounds is exchanged
for hydroxyl and has no tendency to lib-
erate iodine from hydriodie acid. Seliwa-
now ascribed this peculiar behavior of the
chlorine atom in chloroamines to the fact
that, even in combination, it existed as
‘‘hypochlorous chlorine.’? He pointed out
that the chlorine atoms in nitrogen tri-
chloride, NCl,, also showed the same pe-
euliar behavior.
In 1901, Noyes and Lyon,*® in perform-
ing Hofmann’s well-known lecture experi-
ment for demonstrating the composition of
ammonia, observed that, under certain
favorable conditions, the amount of ni-
trogen liberated as free nitrogen was about
one sixth, instead of one third, the volume
revolve in an orbit in a plane perpendicular to the
line joining the nuclei.

of the chlorine used. They explained this
reaction by the following equation:
12 NH, +' 6 Cl, =N,-+ NCl; + 9 NH.Cl.
_ This observation led them to study the
chemical properties of nitrogen trichloride.
They found that each chlorine atom pres-
ent in nitrogen trichloride was equivalent
to two atoms of ‘‘available chlorine,’’ or,
as Seliwanow had put it, the chlorine is
hypochlorous in character. Noyes and
Luyon represented nitrogen trichloride as
follows:
a 526 Gil

and, to account for the reaction between
ammonia and chlorine, assumed that am-
monia may ionize in two ways,
4
N44 3H-2NH,=N = + 3Ht
Hi
and, furthermore, that the chlorine mole-
eule may ionize to give both positive and
negative chlorine ions.
In the same number of the Journal of the
American Chemical Society, Stieglitz? com-
mented upon the work of Noyes and Lyon,
and put forth arguments to show that this
reaction,
H,O + Cl, = HCl + HOGI,
a reversible reaction, was, at the same time,
an ionic reaction. In other words, hypo-
chlorous acid may ionize in two ways,
amphoterically, z
HOCI=H* + OCI
HOCl=HO-+ Ctl.
The chlorine molecule, therefore, must
yield negative chlorine ions, Cl-, and, also,
positive chlorine ions, Cl*.
These deductions, expressed originally
by Noyes and Lyon, as well as by Stieglitz,
in terms of ion formation, have since been
translated into the language of the electron
theory of valence. Thus, the chlorine mole-

cule may be represented electronically by
the symbol, Cl— -+ Cl.
The striking difference in behavior of de-
rivatives of positive chlorine and of nega-
tive chlorine may be illustrated by compar-
ing the two compounds, nitrogen trichlo-
ride and phosphorus trichloride, which, by
virtue of the family relationship of nitro-
gen and phosphorus in the periodic system,
and the similarity in the formulas of the
two chlorides, would be expected to re-
semble one another in chemical behavior
about as closely as any two compounds
could. At the same time, the illustration
will serve to explain the significance of the
statement made in an earlier part of this
paper, viz., that the polar characteristics of
compounds may be revealed by a study of
their chemical interactions.
If the electronic formulas,
=u @ Ll

are assigned to these two substances, we ob-
tain formulas which, unlike those in general
use, Show why it is that the two compounds
are most dissimilar in chemical deportment ;
why nitrogen trichloride, when hydrolyzed,
gives ammonia and hypochlorous acid,
while phosphorus trichloride yields phos-
phorus acid and hydrogen chloride; why
the chlorine atom in nitrogen trichloride
possesses oxidizing properties, while the
chlorine in phosphorus trichloride does
not. The oxidizing value of a positive
chlorine atom corresponds to a gain of two
negative electrons, if a negative chlorine
ion is the final stage in the change.

Certain other halogen compounds have
been found to show similar polar differ-
ences. Thus, Nef? observed that chloro-
cyanogen, upon hydrolysis, gave hydrogen
chloride and eyanic acid, while iodocyano-
gen gave hypoiodous acid and prussic acid,

In fact, there is no difficulty in finding
among organic compounds countless cases
in which the polarity manifests itself
clearly during chemical changes. Thus, in
the case of alkyl cyanides, RCN, it may be
asked what indication there is in the for-
mula itself to lead chemists to predict, un-
erringly, that the products of hydrolysis of
such a compound are always ammonia and
a carboxylic acid. Pure speculation would
suggest that at least four different sets of
products are possible:
(a) RC(OH), and NH;
(b) RCH(OH), and NH,OH;
(c) RCH,OH and NH(OH),;
(d) RCH; and N(OH);.
But the substances expressed under (a) are
the only ones ever realized. That this de-
cision is not inherent in the formula is
emphasized all too forcibly by the fact that
these four sets of products are the very ones
which beginning students offer to explain
the hydrolysis of an alkyl cyanide. In
terms of the electron conception valence,
the explanation lies in the fact that the
nitriles are polar compounds of the for-
mula:
+ =
RC+—WN
In this connection, some recent experi-
ments on mercury dialkyls carried out with
Mr. Werner in our laboratory have led to
the observation that, upon complete hydro-
lysis in the presence of acetic acid, the
SCIENCE
497
products formed are metallic mercury, an
alcohol, and a hydrocarbon. At about 200°,
mereury diethyl decomposes to give mer-
eury and butane. This dissociation im-
plies that the mereury atom in these dia-
lixyls either possesses, or readily assumes,
the condition of reduction which it has in
the metallic state, viz., with an equal num-
ber of positive and negative ‘‘charges.’’
This suggests, also, that the two ethyl
groups may be one negative and the other
positive :
Hg | + Gis — ue
oe =e + CH.+—GH,.
When mercury diethyl is heated with
acetie acid, further evidence in support of
this inference is furnished; a quantitative
yield of metallic mereury is found, and in
addition, ethane and ethyl alcohol (or acetic
ethyl ester). These changes may be ex-
pressed in terms of the electron conception
of valence as follows:

If these reactions of mereury diethyl are
compared with those of zine alkyls and of
oxygen alkyls, the significance of the state-
ment that the polar characteristic of com-
pounds becomes manifest during chemical
changes will be apparent. Thus, zine
alkyls are hydrolyzed to give exclusively
zine hydroxide and a hydrocarbon; oxygen
alkyls give exclusively alcohols.

If, therefore, the atoms in compounds
may function positively or negatively, in
general a univalent atom, A, may be repre-
sented by two electronic symbols, 4 + and
498
A — ; and an atom whose valence is n may
function in (n-+1) ways electronically.
Thus:
A compound formed by the union of the
univalent atoms, A and B, may be repre-
sented by two electronic formulas:
A+—BandA—+B.
These two formulas represent isomers in a
peculiar sense, quite unlike structural
isomers. The difference lies solely in the
distribution of valence electrons. Two or
more compounds related in this manner
have ‘been called electronic isomers, or
electromers.'8
There is a certain resemblance between
electromers and _ structure tautomers.
While the transformation of one tautomer
into another is accompanied by a wander-
ing of an atom from one position in the
molecule to a new position, the transforma-
tion of one electromer into another depends
upon a more subtle change, viz., of elec-
trons, or negative atoms of electricity, from
one position to another within the mole-
cule. Furthermore, it would be expected
that, like tautomers, one electromer would
be more stable than the other, and, in the
majority of cases, that only one form
might be capable of isolation, but that
under certain favorable conditions, both
electromers might be realized.
Moreover, between two electromers there
might exist a condition of equilibrium simi-
lar to that which exists between tautomers
and desmotrops, viz.,
A+—BaA—+B.
Many cases requiring an assumption of
such a relationship have been observed.
One simple illustration will suffice. When

benzene sulphonic acid is subjected to the
action of superheated steam, it yields ben-
zene, C,H,, and sulphuric acid. But if the
same sample is heated with caustic alkalies,
the products are phenol, C,H,OH, and
sulphurous acid (or sulphites). Since ben-
zene and phenole, as well as sulphurous
acid and sulphuric acid, are related as oxi-
dation-reduction products, the question
arises what is the electronic formula of ben-
zene sulphonic acid? To account for the
substances formed in the two reactions, it
must be assumed that two electronic for-
mulas may be assigned to benzene sul-
phonie acid, and that the two substances
represented by these formulas are in equi-
librium as tautomeric electromers*

It is self-evident that the problem of
preparing two or more electromers presents
far greater experimental difficulties than
the separation of structure tautomers has
offered in the past. When, therefore, it is
recalled that von Baeyer observed the first
case of tautomerism while studying isatin,
and that many years elapsed before two
compounds related as tautomers were ac-
tually separated as distinct substances
(desmotrops), it should not be a matter of
surprise that the preparation of actual
electromers has not been more successful
so far.
The first set of experiments, and prac-
tically the only ones, carried out with the
express purpose of preparing electromers,
are those of W. A. Noyes.® Noyes tried to

existence of such an electromer could be
found.
In an article’® published in the Journal
of the American Chemical Society, I pre-
sented evidence, which I believe to be con-
clusive, to show that the certain derivatives
of hydroxylamine, prepared by Meisen-
heimer, represent the first known cases of
electromers, viz., compounds identical in
structural formulas, but dissimilar in chem-
ical and physical properties by virtue of a
different arrangement of valence electrons,
and the concomitant differences in force
fields within the molecules.
A consideration of the properties of hy-
droxylamine, and its various derivatives
and, in particular, the peculiar behavior of
the hydroxyl group-in such compounds, led
me to conclude that this hydroxyl group
could not be regarded as identical with
negative hydroxyl, —OH. This opinion
was expressed by Stieglitz.27
The similar behavior of hydroxlamine and hal-
ogen amines, of hydroxylamine and hydrogen per-
oxide, still more the fundamental similarity exist-
ing between hydroxylamine and ammonia, and
between their salts, and above all, the fact that, as
far as the writer is aware, no hydroxylamine de-
rivative has been found to exchange hydroxyl for
halogen by treatment with halogen acids, or phos-
phorus halides, are facts upon which the writer’s
views are based. (According to a later private
communication from Dr. Jones, he has now reached
the same conclusion in this question and has dis-
covered further evidence supporting it.)
These facts all imply that the hydroxyl
group in hydroxylamine may be positive,

when hydroxlamine is treated with halogen
alkyls. Moist silver oxide converts these
substances into hydrated amine oxides,
R,N(OH),, H,O. The same hydrated
amine oxides may be prepared by the action
of hydrogen peroxide? upon tertiary
amines, R,N. In fact, Hantzsch and Hil-
lard’? suggested that hydrogen peroxide
might react with tertiary amines by addi-
tion and that the reaction may be revers-
ible.
(CH;),N + HOOH = (CH;),;N(OH),.
By careful dehydration of hydrated amine
in vacuo, amine oxides, R,NO, are formed.
These amine oxides and their hydrates
are oxidizing agents, and in this property
show a striking resemblance to hydrogen
peroxide. In fact, Dunstan and Gaulding,
in summing up their behavior, gay:
We conclude that the oxygen is in an ‘‘active’?
condition analogous to the oxygen atom in hy-
drogen peroxide.
Thus, trimethylamine oxide rapidly de-
composes in two ways:
2(CH;),;NO = 2(CH;),N + ©O.,
(CH;);NO = (CH;).NH + CH.O.
These changes, looked at from the point of
view presented by the electron theory,
would lead to the inference that the oxygen
atom in amine oxides should be represented
as follows: R,N = O; and that the hydrated
amine oxides, or their salts, should receive
OH.
xX
If the hydroxyl group in hydroxylamine
be regarded as positive, and if this eondi-
tion of the hydroxyl group be retained in
the alkyl (aryl) derivatives, two inferences
concerning the behavior of substituted
hydroxylamines must follow logically.
In the first place, compounds containing
in their formula the group N — OH, or the

Then, again, provided one of the hydroxyl
groups is positive and the other negative,
compounds of the type, (R),N(OH),
should exist in two isomeric forms (elec-
tromers) when one of the hydrogen atoms
is replaced by a single radical R; and, fur-
thermore, there should be two distinet
isomers (electromers) if two of the hydro-
gen atoms are replaced simultaneously by
dissimilar radicals, R and R’.

In the second place, compounds of the
formula R, R’, R’”, N(OH)., in which there
are three different alkyl (or aryl) radicals
linked to the nitrogen atom, should exist in
stereoisomeric modifications, provided one
hydroxyl group is negative and the other
one is positive. By the action of an opti-
eally active acid, e. g., d-bromocamphorsul-
fonie acid, or d-tartaric acid, a racemic
compound obtained by synthesis should be
resolved into a dextro- and a levo-modifica-
tion. Optical activity might even persist
in the corresponding amine oxides R, R’,
R”’, NO. Although the two hydroxyl
groups are structurally alike, they are
totally different electronically. Conse-
quently, the nitrogen atom is linked to five
different radicals, and, in this respect, com-
pounds of these types may be compared to
substituted ammonium derivations of the
formula R, R’, R”, R’”, N— X, which have

porting both of these deductions has been
presented quite recently.

ing the ‘‘Non-equivalence of the Five

scribes the preparation of two isomeric
compounds of the type

of methyl iodide upon trimethylamine

except for the order in which the hydroxyl

the acid radical; while it is linked to the

these two substances are fundamentally
different. This is easily demonstrated by
a study of their solutions. When a water

In addition to these compounds, Meisen-

mixed dialkyl compounds, with methyl,

— OCH,
(CED Bio wire
and (CHa) Namie:
In every case, water decomposed com-
pounds of this type to give a tertiary
amine, an alcohol and an aldehyde; but, in-
variably, the radical which was eliminated
as aldehyde was the radical which occupied
‘‘nosition four (4)’’ and the group elimi-
nated as alcohol always occupied ‘‘position
five (5).’? Meisenheimer stated that he
never obtained even recognizable traces of
the aldehyde which should have resulted if
the group attached in position five had sep-
arated in that form. His conclusions may
be stated in his own words:
Durch diese Reaktion ist bewiesen dass die
beiden Alkoxygruppen nicht in gleicher Weise an
das Stickstoffatom gebunden sind.
The key to these disputed relations is
easily furnished in terms of the electronic
conception, by assuming that the one hy-

pends, are not linked directly, but through
a third atom, nitrogen.

Here, again, the analogy to structure tau-
tomers appears. Chemists have failed to
prepare desmotrops of prussic acid, and of
many other compounds in which the wan-
dering atom passes from one atom in the
molecule to another directly linked to it.
HCN = CNH.
The majority of successful separations of
desmotrops lie among compounds in which,
similar to the electromers described above,
tautomeric changes involve two atoms not
directly linked, but connected by a third
atom. Thus, in the keto-enol and in the
nitro-nitronic acid desmotrops,

the wandering hydrogen atom passes from
carbon to oxygen not directly linked.
2. Stereomers.—Meisenheimer** was the
first to observe that amine oxides with three
different radicals R R’ R’N =O, could be
resolved into enantiomorphous modifica-
tions. Amine oxides of this kind were pre-
pared by oxidizing tertiary amines with
hydrogen peroxide, or Caro’s acid. Meis-

methylethylaniline oxide, methylethyl-6-
naphthylamine oxide and other similar
compounds,
(CH;) (C:Hs) (CoHs) N =0
(CH;) (C:Hs) (CH:) N = 0.
The racemates were resolved by means of
d-bromocamphorsulfonie acid or d-tartaric
acid. After fractional crystallization and
separation, each salt was converted into
the active picrate, which was changed to
the corresponding active chloride and
finally into the active amine oxide itself.
Previous attempts to resolve compounds
with two like radicals, Na,bed, have been
fruitless. Even compounds more closely
allied to these amine oxides in form, such
as N-methylpicolinium salts, N-methylqui-
nolinium salts, could not be resolved by H.
O. Jones.24 Meisenheimer takes it for
granted that an explanation of the stereo-
isomerism is provided when he has called
attentiom to the fact that, in the amine ox-
ides, the doubly bound oxygen engages the
valence which usually holds the acid rad-
ical, while in the case of the compounds
studied by H. O. Jones, only non-ionizable
valences have been satisfied by doubly
bound carbon.
Tt seems that a more consistent explana-
tion may be offered in terms of the elec-
tronic viewpoint, if the amine oxides and
their hydrates are assigned the following
formulas :
R +—
R’ +—N
R”’ + —
=5' tL Ost
+— OH?
I. II.
Tt must be assumed that the linking in for-
mula II. is similar to the grouping in for-
mula I., in so far as its effect upon the
asymmetry of the molecule is concerned,
since amine oxides dissolved in benzene
often show large rotations. The nitrogen
atom, in either even, does not hold two like
groups, since the properties of positive and

negative hydroxyl are as divergent as those
of positive and negative chlorine. In this
respect, the conditions are not the same as
those in ammonium compounds of the
form, Na,bcd, but are comparable to the
condition existing in ammonium compounds
of the general type, Nabcde.
In conclusion, permit me to express the
belief that chemists will soon come to real-
ize more fully that the recent investiga-
tions into the structure of the atom have a
practical bearing upon their particular
problems. The study of electromers, and
the investigations of the conditions under
which they may be prepared, certainly fur-
nishes an inviting field of research, which,
in my opinion, is worth tilling, and can not
fail to be productive of results of far-
reaching importance to chemists. Fur-
thermore, with our present limited knowl-
edge of the subject, no one can predict in
what manner the discoveries, sure to be
made, may react to modify and clarify our
theories concerning the structure of mat-
ter, and, in particular, our vague notions
of ‘‘chemical affinity.’’

Tuis theme, kindly suggested by Pro-
fessor Sir James Dewar, is sufficiently
large to preclude more than a succinct
treatment of some outstanding points in
the time permissible in a single lecture.
But these points are of considerable inter-
est and have a more than fleeting impor-
tance.
The first is that of fatigue, its measure-
ment and incidence in factory employees.
The indices taken have been speed of out-
put and quantity of output by groups of
workpeople working under the conditions
of ‘a munitions factory. An inference of
1 Address before the Royal Institution of Great
Britain, February 2, 1917.
NoveMBER 23, 1917]
practical value drawn from the observa-
tions is that when the number of working
hours per week was reduced from sixty-two
to fifty-six the output actually increased.
The reduction of the length of the working
day by one hour per diem gave a rise of the
total output of the week from an amount
stated numerically as 6,150 to an amount
expressed as 6,759. The output per hour
increased 22 per cent. The kind of work in
this case was ‘‘heavy,’’ namely, deep screw-
cutting by hand.
In another ease, that of 200 women turn-
ing aluminium fuse-bodies, the reduction of
the working hours per week from 68.2 to
60 notably increased the total output, and
of course still more the rate of output.
From these and other examples the lesson
seems to be that there is for manual labor
a certain length of working week, or work-
ing month, best suited for satisfactory pro-
duction in permanence. The length varies
with the class of the manual work. If a
good efficiency is to be maintained in the
factory this ‘‘most favorable’’ length of
working month has to be followed. Before
that it has to be found out and measured.
The next point raised was the influence
of alcohol on the workers’ output. The
question has at present been attacked only
in the laboratory so far as physiology is
concerned. Physiological experiment shows
that even a large single dose of aleohol—
e. g., 40 ¢.c.—has little or no effect upon
the muscles per se, but that it does impair
the working of the nervous system which
actuates the muscles.
A suitable test in respect of the simplic-
ity of the nervous centers involved in it is
the knee-jerk. This is a familiar reaction
to every physician; it is a reflex act, the
spinal center for which has been thor-
oughly investigated. The effect of a single
dose of alcohol of 30 ¢.ce. quantity diluted
with 120 ¢c.c. of water is to diminish and
render sluggish the knee-jerk; the speed of
SCIENCE
503
the response is sometimes decreased by 9.6
per cent., the amplitude of the response
lessened by 48.9 per cent. The greatest im-
pairment of the reaction was noted about
one hour after the dose.
Another test of the effect of alcohol on
the musculo-nervous actions was furnished
by a very simple voluntary act. The per-
son subjected to the experiment was re-
quired to move one finger to and fro, that
is, to bend and straighten the finger alter-
nately, as rapidly as possible. The rate of
movement was examined before and after
taking a dose of 80 ¢.c. aleohol diluted as
above. This dose impaired the rate at
which the oscillatory movement of the
finger could be performed. The rate was
diminished an hour after the dose by 8.9
per cent.
Such a movement is not well calculated
to test that form of skill which consists in
precision. Reasons were adduced for think-
ing that a precision of movement is that as-
pect of a muscular act which will be most
detrimentally interfered with by alcohol.
The testing of alcohol effect by the ergo-
graph seems to show that a moderate dose,
say 30 c.c. of alcohol, in a person accus-
tomed to moderate use of alcohol, does not
appreciably impair the power of the move-
ment nor its resistance to fatigue. But the
movements chosen as suitable for ergo-
graphic record are such as give little oppor-
tunity for the exhibition of precision or of
skill of any kind.
The next point dealt with was the at-
tempt to devise some fluid which can be in-
jected to counteract the effect of severe loss
of blood in the wounded. The properties
desirable for the required fluid were shown
to be: harmlessness in respect of avoidance
of causing clotting in the circulation; res-
toration of the volume of the fluid in the
circulation ; maintenance of the due degree
of viscosity of the circulating fluid, since
on that factor depends the arterial and
504
capillary pressure; and, finally, preserva-
tion of the balance between the osmotic
pressure of the fluid inside the blood-ves-
sels and outside in the tissues. It was
shown that considerable success had been
reached in this problem by the experiments
of Professor Bayliss and others.
A final point dealt with was the treat-
ment of tetanus by administration of ‘‘anti-
tetanus serum.’’ This serum is obtained
from the blood of horses which have been
subjected to gradually-increasing doses of
tetanus-toxin, the poison produced by the
tetanus-bacillus. The high efficiency of
this anti-toxic serum when used as a pro-
phylactie was first demonstrated on man on
a large scale by its employment in the first
autumn of this war. Curves illustrating
the statistics were shown. The severe out-
break of tetanus which ensued in the
troops at the outset of the campaign was
checked and practically stopped almost, in-
stantaneously by the orders that every
wounded man, as soon as possible after be-
ing wounded, that is to say, at the first field
casualty-station, should receive a small in-
jection of anti-tetanus serum from the im-
munized horse. But the efficacy of the
serum when once signs of tetanus have ap-
peared in the patient is far less satisfac-
tory. The remainder of the lecture was de-
voted to discussion of why this should be,
and in what ways the difficulty may be, at
least in part, overcome.

PRE-MEDICAL TRAINING IN
CHEMISTRY!
As a country we are rubbing the sleep out of
our eyes and wishing we had split the kindling
and brought up the coal the night before. The
alarm clock has been ringing for some time,

but we have preferred our dreams of ease to the
realities of necessities.
The medical profession is awake and trying
to start the water boiling, but finds it can not
lay the fire. The wood and coal are at hand,
but the knowledge of their proper use is lack-
ing. Now, more than ever, do progressive
physicians realize the dependency of successful
practise on a well-founded knowledge of the
chemistry of the human body, and more than
ever do they irritably contemplate their lack
of preparation.
This lack of preparation in a science so ob-
viously fundamental to rational understanding
of the human mechanism as to require no elab-
oration, at present exists; that a continuation
of this condition should be allowed is a parody
upon our intelligence.
The futility of expecting the physician to
utilize all possible sources of relief to suffering
without a knowledge of the application of basic
chemical principles to the body reactions is
apparent.
It is equally as absurd to expect the medical
student to appreciate or assimilate the possi-
bility of chemistry being a practical science
for his uses, if he does not have sufficient
foundation in this subject before he enters the
medical school. The medical school is funda-
mentally a school of applied science. It is
where the individual is taught science as ap-
plied to the human body. Any attempt to
teach a student biological chemistry without
his having received an adequate foundation in
the fundamental principles of chemistry in
general, and to expect him to know much
of anything when we are through with him, is
as idiotic as to try to teach calculus to men
who have yet to know algebra. The foundation
must be laid in the pre-medical work.
It is only in recent years that the teaching
of elementary chemistry has been dropped
from the medical curriculum. Unfortunately
however even to-day it is only the few schools
interested in turning out doctors instead of
groups of men competent to pass State-board
examinations, that have adapted themselves to
the logical demand of the times as justified by
the ever-increasing applicability of chemical
NovEMBER 23, 1917]
science to medical practise, and brought about
this necessary change.
It is admitted that plausible excuse for this
disorderliness exists. The appearance of chem-
istry as a real aid to diagnosis and treatment
from the Stygian darkness has been not only
remarkable for the rapidity of its development,
but amazing in its stability. A new phase in
medical knowledge has been produced through
the pressure of the discoveries of countless in-
vestigators. And it is not surprising that the
now should-be obsolete system clings tenaci-
ously to the older but invalid conceptions.
It is well recognized that the efficient prac-
tise of medicine entails a scientific knowledge
of ever-widening scope. It is therefore of the
greatest importance that a proper selection of
scientific information be presented to the pros-
pective medical student for his assimilation.
Purposeless instruction, from the point of view
of the pre-medical student, is haphazard and
yields results that are worse than nothing.
Conscientious objectors will mentally raise
the objection that the pre-medical requirements
are already well set down in the regulations of
the various medical schools and by the Ameri-
ean Medical Association. From the quantita-
tive standpoint this is largely true, but from
the point of quality the field is barren. And
whereas these dicta were sufficient for the time
and admirable in that an appreciation of the
increasing importance of chemistry to the
practise of medicine was shown, yet such ad-
vantages are now possible to be derived from a
more exact definition of requirements that a
change is imperative, else stagnation will
set in. For mark you, while directions are
given that so much inorganic, and so much
organic, and so much advanced chemistry
should be given, nothing is said about what of
inorganic, and what of organic or what of ad-
vanced should be taught. To chemists it is a
matter of individual experience that any of the
various branches of the science can well occupy
the studies of a lifetime.
So why try to make the pre-medical student
a chemist. He wants to be a doctor, and he
wants to learn what of chemistry there is that
can help him to be a better doctor. But in-
SCIENCE
505
stead of getting what he wants he is put
through the mill with the students who wish to
enter upon chemistry as a life work, gets so
far and no farther, wonders what it is all
about, takes a good dose of physic in the form
of an examination and gets rid of all he had
taken in. If the college instructors of pre-
medical students should look upon them as a
problem in research, the results would never
see the light.
Now this pre-medical training in chemistry
is essentially a question of what instead of
how much, and the decision as to the subject-
matter to be offered for utilization is not espe-
cially difficult if one cares to look into a bio-
logical chemistry for a few hours. What the
pre-medical student needs is to learn the fun-
damental principles common to all chemical
reaction. He does not need encyclopedic de-
tails. Principles are to details as granite is to
points in the work, they should not be ob-
secured by a fog of wearying and relatively un-
important details. Let me illustrate: the
understanding of the nature of oxides is a
principle, the number and formule of the
oxides of iron is an unessential detail, and
again, the phenomena of isomerism is a prin-
ciple, the ability to enumerate all possible iso-
merides of a given compound is detail.
Principle must not be subordinated to de-
tail.
Human health and happiness rests to a great
degree in the physician’s hands. The true
physician must be a true diagnostician. He
can not be a diagnostician if he lacks power of
observation and ability to carry on deductive
reasoning. Where better can he gain this
fundamental training than in chemistry?
And can he get this point of view in a
mind befuddled with inconsequential detail?
Another essential attribute of the efficient doc-
tor is technique. The ability to rapidly,
smoothly and accurately carry on delicate
manipulations is a prime requisite for adequate
medical service. What teaches this better than
intensive training in quantitative analysis?
Can we conclude from the results handed over
to us that these things have been done? We
can not.
506
Any teacher of biological chemistry in a
medical school knows how flimsy a chemical
structure has been erected in the minds of the
students coming to him, and that the informa-
tion acquired is about as useful as is a cobweb
for catching fish.
The causes of this are self-evident. Probably
the most satisfying reason lies in the newness
of the possibilities of the application of the
science of chemistry to diagnosis and treat-
ment. The collegiate instructor has failed to
appreciate the progressive utilization of chem-
istry by the biological sciences. There is a
chasm between what the instructor knows and
attempts to teach to the pre-medical student
and what the pre-medical student needs. And
as a result the student falls into the chasm,
and is lost. It is the job of the collegiate in-
structor to bridge the gap through constructive
cooperation. The medical-school instructor has
not been sufficiently insistent on preliminary
requirements from a qualitative standpoint,
nor has he shown any special inclination to
relate the needs of the situation. These facts
when coupled with the disinclination of the
college teacher of chemistry to break away
from the classical and now obsolete methods of
teaching and inaugurate a system adapted to
the demands of the times give some explana-
tion of what at present confronts us. There is
at hand a supply of potential useful informa-
tion that lacks efficient assimilation because of
the lack of understanding of fundamental
principles.
The remedies are obvious—an attempt by the
collegiate instructor in chemistry to learn
something of what chemistry is doing in biol-
ogy, a measure of cooperation between teachers
of biological chemistry and the pre-medical in-
structors, a willingness on the part of the lat-
ter to recognize the validity of the wishes of
the former, an outline of preparedness from the
qualitative point of view, and a realization
that true preparedness rests on understanding,
while understanding can only come when de-
tail is subordinated to principle.

BRITISH EXPERIMENTAL STATION FOR FUEL
RESEARCH
THe Fuel Research Board of the Depart-
ment of Scientific and Industrial Research
has issued a report, signed by Sir George
Beilby, the director of fuel research, describ-_
ing the scheme of research they have adopted
and their plan for the establishment of a fuel
research station on an industrial scale.
It is stated in the London Times that in a
previous report, which has not been published,
they stated that they had in view two main
lines of research: (1) A survey and classifica-
tion of the coal seams in the various mining
districts by means of chemical and physical
tests in the laboratory, and (2) an investiga-
tion of the practical problems which must be
solved if any large proportion of the raw coal
at present burned in its natural state is to be
replaced by the various forms of fuel obtain-
able from coal by processes of carbonization
and gasification.
At one time it was thought that the former
line of inquiry could be proceeded with in ad-
vance of the second, but further consideration
has shown them to be so interdependent that
they can be most satisfactorily dealt with side
by side. However, in preparation for the or-
ganization of the first line of inquiry, an ex-
perimental study of standard methods for the
examination of coal in the laboratory has been
made, and as the result of work carried out
for the board in the Fuel Laboratory of the
Imperial College of Science a test has been
elaborated which, by direct weighing and
measurement, gives the yields of gas, oil,
water and carbonaceous residue that result
from carbonization at any definite temperature.
Among the problems to be investigated are:
1. Can the 35 to 40 million tons of raw coal used
every year for domestic heating be replaced wholly
or partially by smokeless fuel, solid or gaseous,
prepared by the carbonization of this coal?
2. Can adequate supplies of fuel for the Navy
be obtained by carbonizing the coal at present
used in its raw form for industrial and domestic
purposes?
3. Can supplies of town gas be obtained more
economically and conveniently by methods of car-
NovEMBER 23, 1917]
bonization and gasification other than those now
used in gas works?
4. Can electric power be obtained more cheaply
if the coal used for steam raising is first sub-
jected to processes of carbonization and gasifica-
tion?
5. Will the more scientific development of the
preparation and use of fuel, which would be im-
plied in the successful working out of the forego-
ing questions, enable the peat deposits of the
United Kingdom to take a serious place as eco-
nomic sources of fuel for industrial purposes?
6. Can the use of gaseous fuel in industrial
operations be forwarded by the development of
more scientific methods of combustion in the fur-
naces, muffles and ovens used in metallurgical,
ceramic and chemical operations?
Answers to these questions, the report points
out, will be obtained only by coordinated re-
search carried on the lines of a broad and
well-considered scheme, but at the same time
the Fuel Research Board think it is to be ex-
pected that solutions of some of the problems
will be supplied by workers in the industries,
and they would regard it as a great misfortune
were the establishment of a government or-
ganization for fuel research to result in dis-
couraging or in any way limiting the activi-
ties of outside workers or organizations.
It was realized that the conditions required
for the research station could be fulfilled only
by a site in the neighborhood of a large gas
works. Some months ago the director of Fuel
Research approached Dr. Charles Carpenter,
the chairman of the South Metropolitan Gas
Company, and subsequently Dr. Carpenter on
behalf of the directors of his company, made
the following very generous offer:
1. To lease the government at a peppercorn rent
sufficient land at the East Greenwich gasworks for
the erection of the research station.
2. To prepare drawings and specifications for
the station on lines laid down by the board and to
make contracts for its erection; and
3. To give every facility for the transport of
coal and other supplies to the station and to take
over at market prices the surplus products, gas,
tar, liquor and coke, resulting from the operations
of the station.
The site consists of a strip of level ground,
about 250 feet wide by 700 feet to 800 feet long,
SCIENCE
507
situated on the main siding which connects the
gas works with the South-Eastern Railways
and possessing access to an existing road. The
station, as planned, will be capable of any ex-
tensions required for future researches. Of
the four acres to be leased, only one acre will
be oceupied by buildings under the present
scheme. Further, a large part of the equip-
ment of the buildings will be of a permanent
character and will serve all the general pur-
poses of a research station. Future exten-
sions, therefore, will not repeat this perma-
nent equipment, but will be based upon it.
THE COLUMBIAN INSTITUTE
THE great scientific bureaus of the govern-
ment at Washington with their thousands of
employees dealing with the country’s problems
in every branch of science, and the important
learned societies and scientific establishments
of the national capital, were influenced in
their early growth and development in a
greater or less degree by a scientific. society
which flourished in Washington during the
early years of the last century. The Colum-
bian Institute for the Promotion of Arts and
Sciences, now all but forgotten, was the first
learned society established in Washington, its
organization dating from June, 1816, sixteen
years after the occupation of the city as the
federal capital, and less than two years after
the invasion by the British troops. The
population of Washington was at that time
little more than 10,000, and the repair and
reconstruction of the public buildings was still
in the initial stage. The history, organization
and achievements of this society are fully de-
scribed in an interesting Bulletin of the
United States National Museum by Mr.
Richard Rathbun, assistant secretary of the
Smithsonian Institution, in charge of the Na-
tional Museum.
The objects of the Columbian Institute,
which was chartered by Congress in 1818 for
a term of twenty years, were as a whole very
diversified, those specifically named in the be-
ginning having been almost wholly of a utili-
tarian nature, such as the government has
from time to time assumed and made the basis
of the work of several scientific bureaus.
508
Four years later, however, an organization was
adopted which gave to the Institute the lati-
tude of a comprehensive learned society.
Among all the activities planned only a few
were in any way conspicuously earried out, in
default of the necessary support, the most im-
portant and material of these being the estab-
lishment of a botanic garden and a museum.
The former occupied the extreme eastern end
of the Mall which then approached much
nearer the capitol than at present, and in-
cluded the site of the present United States
Botanic Garden.
Starting with a cabinet of minerals which
remained predominant in this connection, this
feature soon developed into a general though
small museum, containing specimens of zool-
ogy, botany, ethnology, archeology, fossils, etc.
Transferred to the National Institution in
1841, some of the objects are now readily dis-
tinguishable in the United States National
Museum, forming, it may be claimed, the
nucleus of its collections.
The institute obtained its meeting places
and accommodations for its museum mainly
through the favor successively of the execu-
tive departments, the municipal government,
and Congress. It was first located in
Blodget’s Hotel, containing the general post
office and the patent office, followed by the
treasury department and city hall, being
finally assigned a permanent home, in 1824, in
the western addition to the capitol building,
which had just been completed. The use of
the site for its botanic garden was also a
grant from Congress.
However unfortunate in the realization of
its ambitions, the Columbian Institute never-
theless occupied an enviable position among
the earlier associations of this country for the
breadth and importance of its object, even
if they be regarded only in the nature of sug-
gestions, which have since been so fully recog-
nized in the organization of the government
and elsewhere, and for its hearty and unselfish
efforts to carry them out. The Columbian
Institute owed its establishment and early
successes to a masterful mind, that of Dr. Ed-
ward Cutbush, then a surgeon in the Navy,
SCIENCE
[N. S. Vou. XLVI. No. 1195
and the first president of the society, though
acknowledgments are also due to Thomas Law
for the suggestion of such a society at the seat
of government.
The membership of this institute included
a great many of the prominent men of every
walk of life in Washington, among them John
Quincy Adams, Andrew Jackson, John C. Cal-
houn, Henry Clay, and well-known representa-
tives of the Army, the government service, the
medical and other professions.
AWARD OF THE JOHN SCOTT LEGACY MEDALS
AND PREMIUMS AND OF THE EDWARD
LONGSTRETH MEDAL OF MERIT
THE city of Philadelphia, acting on the
recommendation of The Franklin Institute,
has awarded the John Scott Legacy Medal
and Premium to Alfred Rishworth Tattersall,
of London, England, for the “ Midget” Mar-
vel Flour Mill.
This device is a small and simple form of
flour mill, designed to enable local millers to
make a good grade of flour at a comparatively
low cost. It is of especial value in farming
communities in which the flour mills run by
water power have been abandoned.
And has also awarded the John Scott Legacy
Medal and Premium to Max Ulrich Schoop,
of Zurich, Switzerland, for the Schoop Metal
Spraying Process.
In this process, wire of some easily fusible
metal, like zinc, is fed into a device called a
spraying pistol. The wire passes through a
tube and at its end comes into contact with
burning gas, by which it is melted, and the
molten metal is sprayed by an air blast upon
the surface to be covered. The use of this
process has been found to greatly increase the
life of patterns for castings.
The John Scott Legacy Medal and Premium
has also been awarded to Thomas A. McCall,
of South Akron, Ohio, for his inventions em-
bodied in the early development of the Hooven
Automatic Typewriter, and to John H. Pil-
lings, of Hamilton, Ohio, for his inventions
and improvements embodied in its later de-
velopment.
The Franklin Institute has awarded its Ed-
ward Longstreth Medal of Merit to The
NovEMBER 23, 1917]
Hooven, Owens, Rentschler Company, of
Hamilton, Ohio, for the development of in-
genious methods used in the manufacture of
this typewriter.
_ This machine is capable of producing type-
written form letters much faster than they
can be written in the ordinary way.

DISCUSSION AND CORRESPONDENCE
AN EXTRAORDINARY RAINFALL RECORD
Durine a recent visit to the Hawaiian Is-
lands, I had oceasion to do some collecting on
Kauai, the northern island of the group.
While there I made a trip to a region of such
extraordinary precipitation that it seemed
worthy of record.
The island is almost circular in outline,
rather less than thirty miles in its greatest
diameter. It consists for the most part of a
SCIENCE
dll
plateau averaging about 3,500-4,000 feet in ele-
vation, but rising to a little over 5,000 feet at
Mt. Waialeale, almost in the center of the is-
land.
As in all the Hawaian Islands the windward
(NE.) side has a very heavy precipitation,
while on the leeward side the rainfall is very
light.
The central part of Kauai, culminating in
Mt. Waialeale, has the heaviest precipitation of
any station in the Hawaiian group, and can
be equalled by very few regions anywhere,
where rainfall data have been kept. In one
year over 600 inches fell, and for the five
years—1912-1916—the average was slightly
more than 500 inches.
Waialeale is seldom free from rain clouds,
and the precipitation is almost incessant. In
consequence the whole region near it is a bog,
partly covered with a forest of low trees,
thickly draped with dripping masses of mosses
and liverworts, but a good deal of the region,
including the summit of Waialeale, is an open
bog, covered with coarse grasses and sedges,
with a few stunted shrubs and various charac-
teristic bog plants.

THE ROCKEFELLER HEALTH RESEARCHES?
THE third annual report of the Rockefeller
Foundation, the International Health Board
(known previously as the International Health
Commission), deals with the year 1916. The
general summary, which precedes the details
of different states and countries, shows that in
addition to ankylostomiasis, malaria and yel-
low fever have been dealt with, and this would
seem to indicate that the Board is prepared
to tackle all tropical disease where the neces-
sity arises. As regards the first of these
scourges, ankylostomiasis, it is stated that ac-
tive measures to control and prevent the
disease are now in operation in Kentucky,
Louisiana, Mississippi, North and South Caro-
lina, Tennessee, Texas, and Virginia in the
United States; in certain West Indian islands
—Antigua, Grenada, St. Lucia, St. Vincent,
and Trinidad; in British and Dutch Guiana,
Costa Rica, Guatemala, Nicaragua, Panama,
Salvador, in South America; and in Ceylon
and Siam in the East. Such widespread work,
properly controlled as this is, and with no
lack of funds to support it, is bound to do
good, and, though remarkable results can not
be looked for in a few years, nevertheless re-
sults will come, all in due time. To ensure
this, permanency of the work is essential, as
otherwise matters would quickly drift back.
The sanitation of many of the small tropical
towns and villages at the present day is very
similar to that which existed in England a
hundred years ago, and only time and much
labor will bring them into line with modern
sanitary ideas. As many tropical maladies

are insect-borne, study of the habits of the
insects concerned is essential, and engineer-
ing works, large and small, may be required
to abolish their different breeding grounds.
The importance of collective investigation and
organized campaigns in such a task is mani-
fest, and it is here that the great value of
the efforts of the International Health Board
lies. The report describes fully the means
adopted in the fight against ankylostomiasis.
Of great interest also is the work of the com-
mission appointed by the board to inquire into
the problem of yellow fever centers in South
America. The report states that the only
endemic center of the disease in South
America at present is Guayaquil; Ecuador,
though certain sections of Colombia, Vene-
zuela, and the adjacent West Indian Islands
are also under suspicion and require close ob-
servation. The eradication of the disease,
with this knowledge as a guide, is feasible.
The report suggests that Mexico and West
Africa should similarly be examined. Experi-
ments upon the control of malaria have also
been commenced, and these will be extended
in due course. Further, a new school of
hygiene and public health has been established
in Baltimore by the Rockefeller Foundation
in connection with the Johns Hopkins Uni-
versity, and is to be opened this month with
Dr. William H. Welch as director. Three
main purposes will be served by the new school:
first, to furnish trained men on whom the
board may draw; secondly, to serve as a train-
ing center to which students from other coun-
tries may be sent for instruction; and, thirdly,
to provide a laboratory for solving scientific
problems which arise. This Rockefeller
Foundation is a splendid conception. Un-
trammelled by questions of expense, its activi-
ties are unlimited, and the benefits it can and
will bestow upon mankind in the tropics are
inestimable. It is a dream the original work-
ers in tropical medicine often dreamed, and it
has come true. Finally, a word of congratula-
tion is due to Dr. Wickliffe Rose, its able
director-general, for the work he has already
accomplished. Long may he continue to di-
rect its energies.—British Medical Journal.

Press. 1917. 8vo. 779 pages with 408
text-figures.
In the author’s own words the purpose of
his book is to show “that throughout the
whole range of organic morphology there are
innumerable phenomena of form which are
not peculiar to living things, but which are
more or less simple manifestations of ordinary
physical laws.” This'thesis Professor Thomp-
son elaborates in a most interesting manner,
developing with the aid of our fuller knowl-
edge of physical forces and of the conditions
under which they act, the mode of study
initiated by Borelli many years ago, and ap-
plied, more recently, with striking and sug-
gestive results, to several forms of organic
activity by Rhumbler, Leduc, Przibram,
Macallum and others. These results and
many others less familiar receive clear ex-
position, but the book is far from being a
mere compilation, a refreshing originality,
being characteristic both in subject matter
and in the manner of its presentation.
The contest between the vitalistic and
mechanistic views of the phenomena of life
has been carried on by generation after gen-
eration of men and always with the strategic
results of the struggle in favor of the mechan-
ists, as one vitalistic stronghold after another
has fallen. The attack is drawing ever nearer
to the central citadel and Professor Thomp-
son’s book is a massing of the attacking
forces before this citadel. But the author
with all his enthusiasm, recognizes limita-
tions in his resources. “ Nor do I ask of
physics,” he says,’ how goodness shines in
one man’s face and evil betrays itself in an-
other. But of the construction and growth
and working of the body, as of all that is of
the earth earthly, physical science is, in my
humble opinion, our only teacher and guide.”
Psychic phenomena are outside the limits of
his attack. Even with this limitation, how-
ever, the book is one of the strongest docu-
ments in support of the mechanistic view of
life that has yet been put forth.

It would be difficult to give an adequate
résumé of the contents of a book, so crowded
with facts and ideas of the greatest interest
to morphologists; it must suffice merely to
mention some of the problems treated. One
finds an interesting discussion of the physical
factors determining the size of organisms,
especially interesting being the consideration
of the conditions which may determine the
minimum size of a living organism. This is
followed by a chapter on the factors deter-
mining growth and then follow chapters on
the structure and form of the cell, in which
the phenomena of karyokinesis are regarded
as “analogous to, if not identical with those
of a bipolar electric field,’ and the forms
assumed by organisms as expressions of the
law that a liquid film in equilibrium assumes
a form which gives it a minimal area under
the given conditions. In this connection
Professor Thompson expresses the opinion
that in the simpler organism, whose form is
due to the direct action of a particular phys-
ical force, similarity of form is not neces-
sarily an indication of phylogenetic relation-
ship.
The form of the cell in cell-aggregates is
then taken up, the arrangement of the divi-
sion planes being considered as illustrations
of the principle of minimal areas, and the
author then passes on to the consideration of
concretions and spicules. This involves as
an essential problem the question of crystal-
lization in the presence of colloids, a question
concerning which there is much yet to, be
learned. The further discussion of the forms
assumed by spicules leads to their division
into two groups, those of intracellular origin
and those that are intercellular, linear growth
of the former under restraint leading to forms
which have for their mathematical basis geo-
detic curves, while in the case of the latter
the phenomena of adsorption and the deposit
of the crystalline material on interfaces are
held to be sufficient for the explanation of
even the marvellously complicated radiolarian
skeletons.
The mathematical properties of the log-
arithmic spiral as applied to the forms shown
514
by molluscan and foraminiferal shells are then
discussed and from this to a consideration of
the form of horns and tusks the passage is
easy. A brief discussion of phyllotaxis fol-
lows and is succeeded by a chapter on the
shapes of eggs and other hollow structures,
after which one finds an interesting descrip-
tion of the mechanical principles illustrated by
the structure of individual bones and by the
skeleton as a whole. The concluding chapter
is an exposition of Professor Thompson’s
method of comparing the form of different
organisms, or of their parts, by inscribing,
for example, the outline of the skull of
Hyracotherium in a system of Cartesian co-
ordinates and then determining the defor-
mation of the system necessary for a similar
inscription of the outline of the skull of a
horse. A graphic representation is thus ob-
tained of the manner of growth characteristic
of this particular line of evolution, and the
method may thus serve in certain cases as a
test of phylogenetic affinity.
This brief outline may give some idea of
the scope of the book, but it altogether fails
to indicate the interesting and suggestive
manner in which the various topics are
treated. Professor Thompson’s style is marked
by a clearness of expression which makes
every page of interest and his book is one
that may well be recommended as revealing
food for thought and fields for investigation
which have been too much neglected by stu-
dents of morphology. J. P. McM.
Tsimshian Mythology. By Franz Boas. Based
on Texts recorded by Henry W. Tarte.
Paper accompanying the Thirty-first Annual
Report of the Bureau of American Ethnol-
ogy, 1909-1910. Washington, Government
Printing Office, 1916. Pp. 1037; 3 plates; 24
text figures.
The core of this paper consists of English
versions of sixty-four Tsimshian myths and
three war tales, written down for the author by
Mr. Henry W. Tate, a Tsimshian Indian of
Port Simpson, B. C., in his own language, be-
tween 1902 and the year of his death, 1914.
The translations were made by Professor Boas
SCIENCE
[N. S. Vou. XLVI. No. 1195
on the basis of “a free interlinear rendering by
Mr. Tate.”
However, unlike most ethnologists who have
published Indian stories, Professor Boas has
not rested satisfied with the mere printing of
“material,” important as such publication un-
doubtedly is, nor even with the addition of
comparative footnotes. He has made this work
the occasion and the basis for studies of sev-
eral different aspects of Tsimshian ethnology,
and for what is by all odds the best investiga-
tion of the distribution of American myths and
mythic elements which has so far appeared,
one which goes a long way toward satisfy-
ing the often-voiced demand for a concordance
of American myths. Besides the usual tables
of contents, bibliography and alphabet explana-
tory of the characters representing native
sounds used in the work, it contains an intro-
ductory description of the Tsimshian, and,
best of all, a summary of the comparisons and
a detailed index to the references used in the
comparison, the latter prepared with the as-
sistance of Dr. H. K. Haeberlin. In appen-
dices III. and IV. students of American In-
’ dian languages will find useful material re-
garding the speech of the people among whom
these myths were current. The work is also
used as a medium for the publication of seven
Bellabella and ten Nootka tales, by Dr. Liv-
ingston Farrand and Mr. George Hunt re-
spectively.
The longer studies to which reference has
been made are “A Description of the Tsim--
shian, Based on Their Mythology” (pp. 393-
477), a treatise on “ Tsimshian Society ” (pp.
478-564), and finally the “ Comparative Study
of Tsimshian Mythology” (pp. 565-871), al-
ready mentioned as the crowning feature of
this work.
While the value of myths as sources of in-
formation regarding the general ethnology of
the tribe from which they were collected has
frequently been commented upon, so far as I
am aware we have here the first attempt to
write an ethnological description based entirely
upon them. For this reason, if for no other,
the result is of interest. It shows that Tsim-
shian stories contain an incomplete, but upon
NovEMBER 23, 1917]
the whole trustworthy, picture of native life
and thought. On the one hand this must be
supplemented by the introduction of matters
too well known among his people to be ex-
plained by the storyteller, and on the other
by determining in how far the conception of
what ought to be in the social and religious
lives of the people conformed to things as they
actually were.
The discussion of Tsimshian society derives
a large part of its importance from the fact
that it concerns one of the two areas over the
data from which controversies regarding “ the
origin of totemism ” have raged most violently.
Evidence of the entire absence of such a thing
as totemic taboos and of the importance of the
father’s as well as the mother’s clan in the life
of the individual are therefore of interest, as
also the comparative study of the distribution
of crests among the matrilineally organized
peoples of this region. The general discussion
of totemism on pages 515 to 519 should be read
carefully by all interested in that subject.
In his treatment of the evolution of the
north Pacifie clan systems Professor Boas
follows his usual cautious method. He
criticizes adversely the reviewer’s theory re-
garding a former extension of the Tlingit
over what was later the Tsimshian coast,
as also his suggestion that Haida moieties
have arisen as the result of the amalgama-
tion of two distinct peoples. The evidence for
the former view was, however, not entirely tra-
ditional, being based partly on the presence of
a considerable number of animal names in
Haida identical with those in Tlingit, and the
comparative lack of similar Tsimshian names,
although in historic times relations between
the Haida and Tsimshian were much more
intimate than between the Haida and Tlingit.
To prepare the comparative study of Tsim-
shian mythology an enormous amount of pains-
taking work was necessary, particularly in the
analysis of the various versions of the Raven
legend, and future students will be saved an
incalculable amount of labor. Two or three
more efforts of the same kind would result in
the much-desired concordance. The results of
this comparison are summarized on pages 872—
SCIENCE
515
881, the more important points being the fol-
lowing.
As forecasted in JBoas’s “ Indianische
Sagen,” published in 1895, Tsimshian mythol-
ogy is distinguished from the mythologies of
other Pacific coast peoples by the presence of
a large number of tales of inland origin. An
examination of the content of the material gen-
erally shows “that there are a number of very
simple plots, which have a wide distribution,
and which are elaborated by a number of inci-
dents that have a very wide distribution and
occur in a variety of plots.” Comparing Eu-
ropean and North American folk-lore Pro-
fessor Boas finds that “European folk-lore
creates the impression that the whole stories
are units and that their cohesion is strong, the
whole complex very old. The analysis of Amer-
ican material, on the other hand, demon-
strates that complex stories are new, that there
is little cohesion between the component ele-
ments, and that the really old parts of tales are
the incidents and a few simple plots.” There
is a tendency among these Indian tales to shake
off many of their supernatural elements along
the border of their area of distribution, but
this is “counterbalanced by another tendency
of tales to take on new supernatural signifi-
cance.” In conclusion Professor Boas has a
word to say (pages 879-881) regarding the
general theory of mythology, with particular
reference to that widespread impression that
mythic tales represent an attempt on the part
of primitive man to explain the phenomena of
nature. Professor Boas thinks that this belief
is not justified. His conclusion is that the ma-
terial presented in this work “rather empha-
sizes the fact that its origin must be looked for
in the imaginative tales dealing with the
social life of the people.” Still he would prob-
ably not deny that particular applications of
such tales to the explanation of natural phe-
nomena had been attempted at a very remote
period in human history.
“Tsimshian Mythology ” furnishes a notable
addition to the sum of myth material and to
our knowledge of northwest coast enthnology,
but its chief claim to distinction rests on the
great advance which it registers in the com-
516
parative study of myths current among Amer-
ican Indians and in the interpretation of them.

The Genus Phoradendron. By WuituiaM
TRELEASE, Professor of Botany in the Uni-
versity of Illinois. Published by the Uni-
versity. Octavo, pp. 224, pls. 245. Price,
paper, $2.00; cloth, $2.50.
It is fortunate for botanists that the author
of this excellent treatise has made so thorough
a revision of the genus Phoradendron instead
of being content with merely attempting to
straighten out the tangle existing in regard
to the group of related forms hitherto known
as Phoradendron flavescens, as he first con-
templated. The author notes that Engelmann
has shown too great a conservatism in his
published studies of the various forms of
species of the genus, by later withdrawing
segregates of P. flavescens that he formerly had
recognized, and that in continuing the work
of Engelmann, also being influenced by his
views, Torrey allowed a number of forms which
he had designated as new species to lie unpub-
lished in the Torrey herbarium. The author
in addition to making a critical study of the
abundant data and material of North Ameri-
can species collected by Engelmann, Torrey
and others in the great herbaria of this
country, visited those of Europe and extended
the investigation to the collection of West
Indian and South American species by
Urban, Martins and others. This has en-
abled him to make a careful comparison of
numerous types and variants of species of the
genus, and to more carefully discriminate be-
tween varieties and species. He recognizes
962 differentiable forms, most of which he
has classified as species. In this matter he
apparently does not share the conservatism of
Engelmann and Torrey. Of the species he
now recognizes, 154 are listed from North
America and 124 from South America. The
genus is separated into two primary groups,
the Boreales and the A‘quatoriales, plants of
the former are constantly without, and the
latter constantly with cataphyls on their foli-
SCIENCE
[N. 8. Vou. XLVI. No. 1195
age shoots. Both groups contain species
destitute of expanded foliage, which are well
represented by Phoradendron juniperinum in
the southwestern United States. All of our
species-belong to the Boreales, those of Mexico
and Central America to both primary groups,
and those of the West Indies and South
America wholly to the Xquatoriales. These
primary groups are each divided and then
subdivided, making finally in all groups 55
minor subdivisions.
The book contains 224 pages of descriptive
matter including very good and usable keys;
these are supplemented by indexes of col-
lectors, occurrence, and names. The illustra-
tions, 245 full sized plates, are indeed works
of art but are also true to nature. Few books
of this class are so fully and beautifully
illustrated. GrorcE G. Hepecock
MECHANICAL PROPERTIES OF WOOD
DETERMINED
A nuMBER of fundamental laws governing
the properties of wood, such as those covering
the relations between strength and specific
gravity, and between strength and moisture
content, are laid down in a bulletin just issued
by the Department of Agriculture. In this
publication are presented the results of about
130,000 strength tests, probably the largest
single series ever run on one material, made
by the Forest Products Laboratory of the
Forest Service on 126 species of American
woods. The laws derived from the tests cover
the general relations existing between me-
chanical and physical properties of each
species, and also the general relations existing
between these properties irrespective of
species.
The results ought to prove of great value
wherever knowledge of the properties of wood
is essential. They have, for example, made
possible the preparation of accurate tables
showing all the needed strength properties for
the woods used in airplanes. With these as a
basis, specifications can be drawn up to elimi-
nate all material that does not meet the exact-
ing requirements of this highly specialized
use.
NovemMBER 23, 1917]
The data also permit of the proper choice
of substitutes for woods which have become
scarce or unobtainable. Here again the air-
plane may be cited, since the supplies of some
woods ordinarily used in airplane construction
are insufficient to meet the present building
program of the United States and its allies.
Among the relations between mechanical
and physical properties of wood for which laws
have been obtained are static bending-specific
gravity, impact bending-specifie gravity, com-
pression parellel to grain-specifie gravity,
compression perpendicular to grain-specific
gravity, static bending-moisture content; im-
pact bending-moisture content, compression
parallel to grain-moisture content, compres-
sion perpendicular to grain-moisture content,
shrinkage-moisture content.
The bulletin, the authors of which are J.
A. Newlin and Thomas R. C. Wilson, is en-
titled ‘“ Mechanical Properties of Woods
Grown in the United States,” and is No. 556
in the Department of Agriculture series.

A CONVENIENT NERVE HOLDER
For several years past in this laboratory
experiments on chemical stimulation have
formed a part of the routine students’ work
on the physiology of muscle and nerve. In
these experiments we have used a nerve holder
which has proved so simple and convenient
that it seems desirable to suggest it to others.
In its first form it consisted merely of a thin
watch-glass 45 to 50 mm. in diameter,
cemented by sealing-wax to the flattened end
of a piece of 4 inch lead wire 12 inches long.
If the muscle of a gastrocnemius-sciatic
preparation is mounted on a muscle lever, the
edge of the watch-glass may be brought very
near to the muscle and the whole nerve may
be allowed to lie in the liquid to be applied,
SCIENCE

as for example, a solution of sodium citrate or
barium chloride.
The construction is so simple, requiring no
special skill and only a few minutes of time,
that it was used in this way for two or three
years. Later, Mr. L. A. Ray, technician, de-
vised the following more permanent construc-
tion. A small bit of glass rod is fused to the
bottom of the watch-glass. The rod is then
melted and pulled in two at a point about 4 to
+ inch from the bottom of the glass, and is
held in the flame till a small knob forms on
the end. A hole is punched in the flattened
end of the lead rod, the glass rod is inserted
and the joint made fast with cement. The
knob on the end of the glass is held firmly in
place by the cement. The accompanying figure
of a section of watch-glass and rod will make
the whole arrangement perfectly obvious.

THE URINE OF THE HORNED LIZARD
VAUQUELIN,! in reporting the first analysis of
reptilian urine, in 1822, stated that it was com-
posed almost entirely of urie acid, and since
that time this fact has been interpreted by
various observers as an adaptation to the con-
ditions of life in arid regions, where animals
obtain their only external water supply in
very limited quantities in the food substances,
as this type of nitrogenous excretion involves
practically no water loss. The reptiles of arid
regions have been known for some time to ex-
crete practically all of their waste nitrogen in
the form of uric acid and its salts, while, on
the other hand, birds and aquatic and semi-
aquatic reptiles may excrete considerable
amounts of urea.

erémens des serpens que l’on fait voir en ce moment

Two boas, species not stated, were the source of
the urine examined in this ease. Uric acid had also
been associated with reptiles as early as 1793, when
a ‘‘pasty deposit’’ found in the bladder of a tor-
toise by Vieq-d’Azyr was found to contain this

The urine of the horned lizard is excreted
in the dry form at the same time as the feces,
from which it is separated by a constriction of
the common mass, the material voided at any
one time having roughly the shape of a dumb-
bell, one of the enlargements being composed
of urine and the other of fecal matter. The
following figures for the composition of the
urine of Phrynosoma cornutum (specimens ob-
tained at Alamogordo, N. M.) have been ob-
tained recently in the laboratory of physiolog-
ical chemistry of the University of Illinois,
the work having been undertaken at the sug-
gestion and under the direction of Dr. H. B.

It will be noticed from the above figures that
uric acid accounts for practically the total
amount of nitrogen present, and that there is
no urea. The small amount of ammonia is
probably present as ammonium urate. The ash
present is mostly composed of foreign mate-
rials (sand grains, ete.) inseparable from the

This new physiology is particularly adapted for high schools and general colleges. It is
written by a teacher who has not lost the point of view of elementary students. Professor
Stiles has the faculty of making clear physiologic processes more or less difficult of com-
prehension. This he does by the use of homely similes and happy teaching devices.

Fascinating Jungle Studies of Jungle Life
TROPICAL WILD LIFE
IN BRITISH GUIANA
Being Zoological Contributions to science, from the Tropical Research

Octavo, cloth, gilt top and side stamp, 504 pages, 4 colored plates and 140 other illustrations
This remarkable volume sets an entirely new pace in the study of wild life. The three
naturalist authors went to a South American jungle
that was teeming with animal life, lived there
under most advantageous conditions, and for several months indulged in a genuine orgy of observa-
tions and studies of tropical wild life as that life was lived and developed from day today. The key-
note was the evolution and development of interesting and little known forms.
The studies so beautifully revealed in this fascinating volume embrace such bird species as
the wonderful tree-climbing hoatzin, various toucans, tinamou, jacanas, anis, nighthawks, fly-
catchers, antbirds and many others. The reptiles were the giant marine toad, the deadly bush-

The volume tells the whole story of the Research Station, its work and surroundings. It
shows how it will expand in the future, offering splendid opportunities for investigation to pro-
fessors, students and nature lovers.
As a vivid exposition of tropical life in a rich South American
jungle, it is unique and unrivalled. The wealth of skillfully made photographs, colored plates,
maps and diagrams, brings the whole of the subject matter into the reader’s grasp.

THE PRODUCTION OF SCIENTIFIC
KNOWLEDGE?
THE great value of scientifie research
both ‘to the industries and to the nations at
large is now generally recognized through-
out the world and the last few years have
seen a remarkable increase in the efforts
made to stimulate the production of scien-
tific knowledge. In 1914 the American As-
sociation for the Advancement of Science
appointed a Committee of One Hundred to
inquire into the steps which should be
taken for the increase of scientific research
in the United States and the work of this
committee has been continued and ex-
panded by the National Research Council.
Among the European nations there is a
great awakening to the national value of
scientific research. The British government
has appointed a Department of the Privy
Council to deal with the subject, while it is
announced that in France a new national
laboratory on a very large scale has been
projected. In Australia the government
has appointed a special department to con-
sider what steps should be taken for the or-
ganization and development of research
work in the Commonwealth, and in Canada
the matter has been the subject of govern-
ment inquiry and solicitude.
The increase of scientific knowledge can
be divided into three steps: first, the pro-
duction of new knowledge by means of
laboratory research; second, the publica-
tion of this knowledge in the form of papers
and abstracts of papers; third, the diges-
tion of the new knowledge and its absorp-

tion of the Optical Society of America, October 23,

tion into the general mass of information
by critical comparison with other experi-
ments on the same or similar subjects.
The whole process, in fact, may be likened
to the process of thought. We have first
the perception by means of the senses. The
percept is then stored in the memory and
in the mind is compared with other previ-
ously stored percepts, and finally forms
with them a conception.
I desire in this paper to consider the
methods by which these three sections of
the production of knowledge may be car-
ried on, to suggest an arrangement of lab-
oratories to produce experimental results
dealing with any branch of science, then to
consider how the knowledge so obtained
may best be stored and classified and finally
the methods to be employed to make the
results of scientific research available for
application.
1. RESEARCH WORK
The agencies engaged in scientific re-
search are of several kinds. The tradi-
tional home of research work is in the
university, and the bulk of the scientific
production of the world comes from institu-
tions connected with teaching. The indus-
tries are more and more supporting re-
search laboratories, a large number of
which contribute to the general fund of
scientific knowledge by publishing the re-
sults which they obtain, and some of which
are engaged upon purely scientific work of
no mean order. Consulting and technical
laboratories engaged in industrial work
make frequent contributions to science, and
there are some very important laboratories
engaged in pure research work which are
supported by philanthropic foundations.
The classification of research laborator-
jes is not altogether an easy task. They
may obviously be classified according to
the source of the funds which support
them; that is, we may classify them as uni-
SCIENCE
[N. 8S. Vou. XLVI. No. 1196
versity laboratories, industrial laborator-
ies, government laboratories, institution
laboratories, and so on, but if we look at
them simply in the light of the research
undertaken, this does not seem to be alto-
gether a logical classification since there is
little distinction between the work done in
some university laboratories and some in-
dustrial laboratories, and the work of the ©
government and institution laboratories
again overlaps that of the two former
classes.
The University of Pittsburgh, for in-
stance, has an industrial laboratory where
definitely technical problems are dealt
with. The research work on photometry
done at Nela Park and at Cornell Univer-
sity would seem to be similar in kind, and
work on physical chemistry or on the struc-
ture of chemical compounds is of the same
type, requires the same class of workers,
and produces the same results, whether it
be done in a university, in a laboratory of
the Carnegie Institution or in such an in-
dustrial laboratory as that of the General
Electric Company. It is equally difficult
to classify laboratories according to the
purpose for which researches are avowedly
carried on. Most university laboratories
are willing to undertake work of industrial
value, and, indeed, some specialize in such
problems; while many industrial labora-
tories are quite willing to carry out a re-
search of purely academic and theoretical
interest provided the problems involved
bear a relation to the general work of the
laboratory.
A useful classification of laboratories can,
however, be obtained if we consider
whether the problems investigated in a lab-
oratory are all connected with one common
subject or whether the problems are of
many kinds, having no connecting bond of
jnterest. I would suggest that the first
type of laboratory might be called ‘‘con-
NovEMBER 30, 1917]
wergent’’ laboratories and the second ‘‘di-
vergent.’’’
In the ‘‘divergent’’ group of laborator-
jes are included all those institutions
where research is carried on which are in-
terested in science in general or in science
as applied to industry and which will at-
tack any problem which may seem to prom-
ise progress in knowledge or, in the case of
an industrial laboratory, financial return.
Most university laboratories are of this
type. When they devote themselves to spe-
cial problems it is usually because of the
predilection of some professor, and as a
general rule a student or instructor may
choose any problem in the whole field of
the science in which he is working and may
carry out an investigation on that problem
if he be interested in it without regard to
the relation of his work to the other work
which is carried on in the same laboratory.
Correspondingly, in most industrial lab-
oratories the problems investigated are
those which present themselves as a result
of factory experience or of suggestions
‘from the men working in the laboratory
and which promise financial return, and
the different problems carried on in the
same laboratory are not necessarily related
in any way whatever.
The greater number of university and in-
dustrial laboratories are necessarily of this
type. It would be a disadvantage for a
university laboratory, whose primary busi-
ness is training students, to be too nar-
rowly specialized. Specialized university
laboratories are only desirable in the case
of post-graduate students, and it would be
wery inadvisable to allow the laboratories
responsible for the general training of sci-
entific men to specialize in one branch of
science, since as a result the students would
acquire a proper acquaintance with only a
limited portion of their subject.
Industrial laboratories, on the other
hand, must necessarily be prepared to deal
SCIENCE
521
with any problems presented by the works,
and as these will be of all kinds, covering
generally the whole field of physics, chem-
istry and engineering, it is impossible for
the usual works laboratory to specialize ex-
cept in so far as it deals with the works
processes themselves.
In the ‘‘convergent’’ laboratories, how-
ever, although the actual investigations
may cover as great a range of science as
those undertaken in a ‘‘divergent’’ labora-
tory, yet all those investigations are di-
rected toward a common end; that is,
towards the elucidation of associated prob-
lems related to one subject. Thus, the staff
of the Geophysical Laboratory, which in-
cludes physicists, geologists, erystallog-
raphers, mineralogists and chemists, works
on the structure of the rocks, and although
the field of the actual investigations ranges
from high temperature photometry to the
physical chemistry of the phase rule, yet
the results of all the work carried out are
converged on the problem of the structure
and the origin of the earth’s crust.
The Nela Park Laboratory, in the same
way, is studying the production, distribu-
tion and measurement of illumination, and
all its work, which may involve physiology,
physics and chemistry, is related to that
one subject. Such convergent laboratories
sometimes develop in universities owing to
the intense interest of a professor in a
single subject and to the enthusiasm which
inspires students and assistants to collabo-
rate with him and to concentrate all their
energies on the same group of problems.
There are many examples of such labora-
tories, such as the laboratories dealing with
radio-activity, and those which are con-
cerned chiefly with spectroscopy. Among
others may be mentioned the Cavendish
Laboratory at Cambridge and several of
the larger university laboratories which
deal with the physical chemistry of solu-
tions.
922
But these university laboratories are
rarely able to concentrate on to the group
of problems which they are studying spe-
cialists from such different branches of
science as are available for similar labora-
tories outside the universities owing to the
fact that it is very difficult to obtain inter-
departmental cooperation in research in a
university. In a specialized laboratory, on
the other hand, workers in all branches of

science may well collaborate in the investi-
gation of problems representing different
points of view of one general subject.
In addition to the examples of industrial
and institutional laboratories mentioned
above I should like to illustrate the struc-
ture of a convergent laboratory, if I may be
forgiven for doing so. by referring to the
organization of the research laboratory
with which I am connected—that of the
Eastman Kodak Company.
ences to photographic problems are shown
in graphic form in Fig. 1.
Optics deals on its geometrical side with
the materials used in photography—cam-
eras, lenses, shutters, ete.-—and on its phys-
ical side with such materials as color filters
and iluminants, but especially with the
study of the relation of the photographie
image to the light by means of which it was
produced—a study which is known by the
name of sensitometry. The manufacture
NoveMBER 30, 1917]
of the sensitive material itself, which in the
ease of modern photographic plates, films
and paper is called the emulsion, is a proy-
ince of colloid and physical chemistry, col-
loid chemistry dealing with the precipita-
tion and nature of the sensitive silver salts
formed in their gelatine layer, while phys-
ical chemistry informs us as to the nature

of the reactions which go on, both in the
formation of the sensitive substance and in
its subsequent development after exposure.
The organic chemist prepares the reduc-
ing agents required for development and
the dyes by which color sensitiveness is
given to the photographic materials and by
which the art of color photography can be
carried on, and while the physicist there-

fore deals with sensitometry and the theory
of exposure, the chemist must deal at the
same time with the theory of development
and with the conditions relating to the de-
velopment of photographie images.
A laboratory, therefore, for the study of
photographie problems must be arranged
with a number of sections such as are

shown in Fig. 2. In physics we require
departments dealing with sensitometry and
with illumination, reflection and absorption,
colorimetry, spectroscopy and geometrical
optics. We need a department of colloid
chemistry, one of physical chemistry, one
of organic chemistry, one of photo-chemis-
try to deal with the action of light upon
the plate, and finally a number of photo-
524
graphic departments, dealing with photo-
graphic chemistry, with portraiture, color
photography, photo-engraving, motion pic-
ture work and X-ray work, and all these
departments are converged together first
upon the theory, and then upon the prac-
tise, of photography.
PHYSICS
Each research specialist in the labora-
tory is given work corresponding to a lim-
ited field of science, so that while his special
attention is devoted to that one depart-
ment his field of activity just overlaps that
of the departments on each side of him,
while his general knowledge of the subject
should, of course, cover a much wider
range. It is important that each man
should have his own special field of work
and that overlapping should not be com-
plete since such complete overlapping will
inevitably produce friction destructive of
cooperation and harmony. The way in
which such a subdivision is arranged may
perhaps be best illustrated by Fig. 8, which
shows the range of the specific investiga-
tions of those who in our laboratory cover
the range of research work between sensi-
tometry and pure physical chemistry.
There are five workers in this range; the
first, A, being a pure physicist; B, a physi-
cist with a considerable experience of chem-
istry ; C, a physical chemist who has special-
jzed in photography; D, a_ physical
chemist who has specialized in photographic
theory; and HZ, a pure physical chemist.
The interest of each of these workers over-
laps the field of the other workers but
nevertheless each of them has his own spe-

LN. 8. Vou. XLVI. No. 1196
cific problem, his own equipment and appa-
ratus. Thus, A and B use sensitometric
apparatus chiefly; C, both sensitometrie
apparatus and the thermostatic and elec-
trical equipment of physical chemistry ; D,
microscopic apparatus and chemical appa-
ratus dealing with the precipitation of

CHEMISTRY
silver salts; and Z, the analytical and solu-
bility apparatus of chemistry.
The whole of this range is also connected
with colloid chemistry and especially the
overlap of the different sections involves
colloid problems, so that we can consider
colloid chemistry as dealing with the inter-
relations of the different sections of photo-
graphic chemistry and can represent its
province in the diagram by shading the
overlapping areas. The colloid division of
the laboratory will therefore be interested
in the work of each of the specific investi-
gators and will be of assistance to all of
them.
These charts, prepared for a photographie
laboratory, are equally applicable in form
for almost any other convergent laboratory,
so that if we have to work out the organi-
zation of a research-laboratory which is to
study any inter-related group of problems,
we can do it by the construction of charts
similar to these. Thus, considering Fig. 1,
we place first at the bottom of the chart the
general subject considered and its various
branches and then above these the scientific
problems involved, separating out on oppo-
site sides of the chart those problems which
would involve different branches of pure
science. Thus, we can place on one side
NoveMBER 30, 1917]
biological problems, then physical prob-
lems, then chemical problems and so on, so
reconstructing a chart similar to Chart 1
from the bottom up until at the top we
have the various branches of pure science
involved, subdividing these branches until
each subdivision represents the work ca-
pable of being handled by one man in the
laboratory.
It will now be possible to draw Fig. 2,
showing on the cireumference the different
sections of the laboratory for which ac-
commodation, apparatus and men must be
provided and showing the relation of these
sections to the problem as a whole, and
having worked this out it is easy to find the
amount of space and the number of men
which will be required or which the funds
available will allow for each part of the
work.
Specialized laboratories may originate in
various ways, but it seems clear that with
an increasing total amount of research and
with an increasing realization of the im-
portance of research more laboratories will
be developed and no doubt laboratories
which originally were of the divergent type
will with their growth tend to split into a
linked group of convergent laboratories.
Consider, for instance, a very large indus-
trial research laboratory covering a wide
field of research and dealing with many
different types of problems. There are two
types of organization possible to such a
laboratory. It might be divided according
to the branches of science in which the
workers were proficient. It might have, for
instance, chemical divisions, physical divi-
sions, and so on, but if the groups of prob-
lems dealt with were reasonably permanent
in their character it would more probably
develop into a group of convergent labora-
tories in which men from different branches
of science—chemists, physicists and so on—
worked together (and probably even had
their working places in proximity) because
SCIENCE
525
they were working on the same general
problem. Any national laboratory which
is developed for industrial research, for
instance, should almost certainly be organ-
ized as a group of convergent laboratories
rather than as a group of separate physical,
chemical, engineering, etc., laboratories.
We may expect then that the general or-
ganization of scientific research will tend
towards the production of numbers of spe-
cialized laboratories, each of which will be
working on an inter-related group of prob-
lems and attacking it from various stand-
points.
Some of the questions relating to the in-
ternal organization suitable for these con-
vergent laboratories have already been dis-
cussed in a former paper? and I need only
add here that the ‘‘conference’’ system de-
scribed there as a method of actually carry-
ing on the scientific work of the research
laboratory has continued to prove quite
satisfactory.
2. THE CLASSIFICATION OF SCIENTIFIC
KNOWLEDGE
The work of the research laboratories is
published by various methods in the form
of scientific papers, and with the increas-
ing amount of research done the number of
technical journals is increasing steadily,
so that the workers in most branches of
science find it difficult to keep up ade-
quately with the current literature and
especially those who become interested in
the light thrown upon their own problem
by other branches of science find it a task
of great magnitude to acquaint themselves
adequately with the literature. In order
to meet this difficulty the various scientific
societies publish journals giving abstracts
in-a conveniently indexed form of all the
important papers published, and these ab-
stract journals are of great value in search-
ing for information on special subjects.
2‘¢The Organization of Industrial Scientific Re-
search,’’ SCIENCE, 1916, p. 763.
526
In spite of these abstract journals the
task of obtaining all the references to the
literature on a given subject is still a
formidable one and might be very much
simplified by the adoption of some radical
changes in the organization of the abstrac-
tion and classification of scientific knowl-
edge.
In the first place, there seems to be no
reason why abstracts of scientific papers
should be prepared by the national so-
cieties. At present, for instance, there are
at least four complete sets of abstracts of
chemical papers prepared in different coun-
tries, together with a number of less com-
plete sets, and this represents a great over-
lapping and duplication of effort. On the
other hand, sciences which have not so
many or so wealthy workers as chemistry
ean not afford to produce any complete ab-
stract journals, so that in these sciences
reference to the literature is much more
difficult. There seems to be no reason why
an interchange of abstracts between differ-
ent countries could not be arranged and,
indeed, it might be the best method of ob-
taining abstracts to have the author of a
paper supply an abstract suitable in form
and length for the abstract journal at the
same time that he sends his paper in to the
journal which publishes it. The editor of
that journal could suggest modifications in
the abstract which in his opinion were de-
sirable and forward both the corrected and
uncorrected abstract to the editor of the
abstract office, where it would be re-edited
for insertion in the international abstract
journals and these journals would, of
course, be supported by subscriptions
either through the societies or individuals
in the same way as the abstract journals
which are at present published.
Whether such an ambitious scheme of
international scientific abstracts is capable
of realization or not, reference to the ab-
stract journals would be made much
SCIENCE
[N. S. Vou. XLVI. No. 1196
simpler if some method of numerical classi-
fication could be adopted.
In this connection, an experiment has
been made in the last two years at the lab-
oratory of the Hastman Kodak Company
which has proved successful and which
seems to be worth trying on a larger scale.
The laboratory publishes each month for
the use of the employees of the company an
abstract bulletin of the photographic jour-
nals, including also abstracts from other
scientific journals which have any relation
to photographic problems or manufacture,
the abstracts being made by the laboratory
staff, and attached to each abstract is a ref-
erence number: These numbers refer to a
numerical classification of photography
based somewhat on a decimal system but
adapted to the special needs of the subject.
Each month as the bulletin is issued the
abstracts are clipped out, pasted on cards
and filed under the number printed on
them in numerical order so that each recip-
ient of the bulletin can prepare for himself
a file either of all photographic literature
or of any portion of it in which he may be
specially interested. For example, in the
classification photographic apparatus com-
mences with the number ‘‘2,’’ and if any
particular worker is not interested in any-
thing but apparatus, if he has no interest
in materials or in photographic processes
or in applications of photography, then he
need only file the cards starting with ‘‘2,”’
while, if his interests are even more lim-
ited, if, for instance, he is interested only
in photographic shutters, he can file the
cards starting with ‘‘262’’ thus obtaining
only a very limited file which is, however,
complete for the subject in which his inter-
est lies.
If the abstract journals would print such
a numerical classification attached to each
abstract, adopting as their basis either the
numerical classifications of the interna-
tional catalogue of scientific literature,
NovEMBER 30, 1917]
which have proved themselves satisfactory
after trial, or some different classification
adopted after due consideration, then each
recipient of the abstract journals could
prepare for himself card index files of the
scientific literature in which he was inter-
ested.
To prepare a card index of all science or
even a complete index of one large branch
of science in this way would be too
formidable an undertaking either for
an individual or even for a small library,
but it should certainly be possible for large
libraries such as those of the scientific so-
cieties or of large cities to keep such nu-
merically indexed files to which reference
could be made by correspondence from any
research worker. Thus, adopting the
classification of the international catalogue,
a worker who became interested in ques-
tions, e. g., of catalysis, could apply for a
copy of the reference cards on this subject,
which would include all those indexed
under 7065 and could be supplied with a
complete file or with a partial file covering
any period of time; the copies could easily
be made by photographing the cards with
such a camera as the ‘‘Photostat.’’
3. THE UTILIZATION OF SCIENTIFIC
KNOWLEDGE
The actual application of science to in-
dustry is so vast a subject that it can not
be considered here, but it is not satisfac-
tory to leave the results of research at the
point where they are published in papers
and filed in the abstract journals. In
order to make them available as a part of
scientific knowledge the new information
as it is obtained must be incorporated in
books.
There are three classes of books dealing
with scientific work which require separate
consideration. The first class comprises the
dictionaries, in which almost all the prog-
ress in some branches of science can con-
SCIENCE
527
veniently be summarized. Beilstein’s
“Handbook of Organic Chemistry”? is a
good example of the way in which almost
all the facts of a science can be absorbed in
a classified form and made available for
ready reference. These dictionaries, in
fact, represent the critical and discrimina-
ting summary of the scientific publications
on the subjects with which they deal and
the preparation of such dictionaries should
be ensured by international cooperation of
the national societies.
Other sciences, however, do not by their
nature lend themselves to the convenient
preparation of dictionaries and what is
wanted in this case are critical and well ar-
ranged handbooks covering the whole sci-
ence and resuming impartially but criti-
cally the various additions which are made
from time to time in the different branches
of the subject. These handbooks as well as
the dictionaries would, of course, require
the addition of supplementary volumes
from time to time and occasional complete
revision.
The preparation of both dictionaries and
handbooks would, of course, be greatly fa-
cilitated by the existence of a numerically
classified card index to the literature con-
cerned, and the preparation and revision of
such books might well be undertaken in con-
nection with the large libraries having in
their possession the complete classified card
indexes.
On the other hand, for the assistance of
advanced students of science, what is re-
quired is a steady supply of monographs
correlating critically and comprehensively
all the literature in a special field, and
these must be brought up-to-date from time
to time. Such monographs are especially
required in connection with rapidly devel-
oping new branches of science; it is difficult
to overestimate the importance and value
for progress in research of such a book as
Bragg’s ‘‘X-Rays and Crystal Structure’’
528
for instance, and while nothing should be
done to hinder individual initiative in pub-
lishing such books, it would seem that when
it was apparent that some branch of sci-
ence required such a monograph a national
society might very well approach well-
known workers in the field and request
them to write such a book, offering its as-
sistance in the matter of bibliography and
also offering to arrange for the publication
of the manuscript. The initiative in indi-
eating the need for such a book might come
in the form of suggestions from members
of the society or other scientific men. It is
quite true that at the present time the sci-
entific publishers are extremely active in
searching for suitable books to publish, but
necessarily they must consider the probable
demand rather than the actual need for a
book, and this leads to an over-production
of books dealing with those fields of science
which have a large following and an insuffi-
cient supply of books in those fields where
the workers are few, though for progress
the more sparsely worked fields would seem
to require almost as much representation
in literature as those which are of wider in-
terest.

power that in the last analysis knows no law
but might. The nation was living on a peace
basis and was not fully prepared for war
in any respect; but it was fortunately circum-
stanced in the character of its agricultural
organization and the number and efficiency
of its expert agencies.
The nation may well pride itself on the
fact that it had had the foresight generations
ago to lay deep its agricultural foundations.
I congratulate the representatives of the land
grant colleges on the fine opportunity for
service presented to them and on the splen-
did way in which they have seized it. The
Department of Agriculture has had great
comfort in the thought that these institutions,
ably planned and wisely directed, existed in
every part of the nation and stood ready not
only to place themselves at the service of the
national government but also to take the
initiative in a vast number of directions.
When a state of war was declared on April
6, the food situation was unsatisfactory. The
need of action was urgent and the appeal for
direction was insistent. The nation looked
for guidance primarily to the federal depart-
ment and to the state agencies which it had so
liberally supported for many generations. It
was not disappointed. In a two-days’ session
at St. Louis, the trained agricultural officers
of the country conceived and devised a pro-
gram of legislation, organization and prac-
tise the essential features of which have not
been successfully questioned and the sub-
stantial part of which has been enacted into
law and set in operation. This great democ-
racy revealed its inherent strength.
To the normal forces of the government
leading with agriculture and rural problems
there has been added an emergency agency
with great and unusual powers, with enorm-
ous possibilities for good, and with a remark-
NovEMBER 30, 1917]
able record for achievements already to its
eredit. It has enlisted in its ranks men of
wide experience, fine spirit, and high ideals,
many of whom are gladly volunteering their
services for the common cause. I refer to
the Food Administration under the direction
of Mr. Hoover.
The relation between this agency and the
other organized agricultural forces of the
nation is intimate dnd fundamental. It is
impossible completely tto disassociate them and
it would be undesirable to do so.
The problem in part is a common one, and
it is of the first importance that the work
be. done in the closest cooperation and with
an eye single for the public good. There is
no need for undue duplication of effort and
no causes of friction which can not be re-
moved through an intelligent conception by
each agency of the powers and purposes of all
and by a spirit of mutual accommodation. In
a broad way it is agreed that the prime func-
tion of the Department of Agriculture shall
be the stimulation of production, the con-
servation of products on the farm through
all the normal and approved processes, the
promotion of better marketing and distribu-
tion of products from the farms to the
markets, the prosecution of the work in home
economics along usual lines, the dissemina-
tion of information, and the extension of all
these activities as authorized by law. In a
similar way the principal function of the
Food Administration is the control and
regulation of commercial distribution of
foods; that is, of products which have reached
the markets, are in the channels of distribu-
tion or in the hands of consumers, their con-
servation by consumers, the elimination of
waste, and the handling of foods and feeds
in the market by legal means through its
regular officials as well as through its volun-
teer agencies.
In the main the Department of Agriculture
deals with all the processes of farming up
to the time products reach the market until
they are in the requisite form for consump-
tion and are available for the purpose. At
SCIENCE
529
this point the Food Administration enters
and exercises its wide powers of regulation,
direction, and suggestion. Where the Food
Administration through its powers can be
of assistance to the Deparament of Agricul-
ture in its field, it is at liberty freely to
make suggestion, and, when necessary, to co-
operate in execution; and the same relation
obtains as to the department’s participation
in Food Administration matters in which it
has a vital interest and toward the promo-
tion of which it can be of assistance. This is
the substance of the agreement originally
entered into between the Food Administra-
tion and the Department of Agriculture, and
will be more satisfactorily observed as the
agents and divisions of the two departments
familiarize themselves more fully with their
tasks and with the prescribed lines of effort.
Obviously the making of a program for
the agricultural activities of the nation did
not end with the St. Louis conference.
Thought, action, and cooperation between the
members of this association and other state
agencies on the one hand and the federal
department on the other have been continu-
ous. Attention has been given without cessa-
tion to problems in the field of labor. It was
obvious that difficulties would be presented
and that apprehension would run beyond the
actual condition. An army could not be
raised without taking men from every field
of activity; and it would have been unfair
to any class of workers in the community
to have proposed its exemption. It was im-
possible in the haste of the first draft satis-
factorily to work out in detail the principle
of selective service; but, nevertheless, under
the regulations, consideration was given
throughout by exemption boards and by the
officers of the War Department to the needs
of agriculture. With ampler time at its dis-
posal, the War Department has worked out a
system of classification which gives due re-
gard to the necessity of retaining skilled
farmers and expert agricultural leaders on the
farms and ranches and in the educational and
administrative services.

Owing {to the unprecedented demand for
railroad service for the nation’s defense, pre-
ferential rates for individual travel have
been tentatively abandoned. The New Eng-
land Passenger Association, however, has au-
thorized local fares in each direction to its
boundary points going and returning via same
route only and over which one-way tickets are
regularly sold—one and one half westbound
differentials to apply, added to fares tendered.
The Trunk-Line Association has authorized
the following: “Two cents a mile in each
direction, with minimum of $1 for tthe round
trip, going and returning via same route only;
tickets to be sold and good, going, December
26 to 28, and returning to reach original
starting point not later than January 5, 1918.”
All members living beyond the boundaries
of the above passenger association territori-
ties should consult their local passenger ticket
agents. Members from west of the Missis-
sippi should consult their local ticket agents
for trans-continental and winter tourist rates.

SCIENTIFIC EVENTS
SMITHSONIAN EXCAVATIONS IN NEW MEXICO
An expedition organized by the Bureau of
American Ethnology of the: Smithsonian In-
stitution and the Museum of the American
Indian, Heye Foundation of New York City,
under the immediate direction of Mr. F. W.
Hodge, ethnologist-in-charge of the Bureau
mentioned has concluded its first season of
excavating among the ruins of Hawikuh in
western New Mexico. This pueblo was one
of the famed “ Seven Cities of Cibola” which
was seen by Marcos de Niza, a Franciscan
Friar, in 1539 and was the scene of the death
of his negro guide and companion. In the
following year the pueblo was stormed by
Francisco Vasquez Coronado, the celebrated
Spanish explorer, who almost lost his life in
the attack. The Zuni occupants of Hawikuh
fled to their stronghold a few miles away; the
Spanish took possession of their village, which
Coronado called Grenada, and while there
wrote his report to the Viceroy of Mexico,
giving an account of his expedition up to
that time and sending various products of the
country and examples of native art.
The excavations were commenced at the
close of May by Mr. Hodge, assisted by Mr.
Alanson Skinner and Mr. E. F. Coffin of the
Museum of the American Indian. Work was
begun in a great refuse heap forming the
western slope of the elevation on which Hawi-
kuh is situated. This refuse was found to
contain many burials of Zuni dead, of which
there were three types—remains cremated and
deposited in cinerary vessels accompanied by
food and water vessels; others buried at
length, or in abnormal postures without ac-
companiments; and usually dismembered;
others still deposited at length with head di-
rected eastward and with them numerous
vessels of earthenware, great quantities of
SCIENCE
[N. 8S. Vou. XLVI. No. 1196
food, and the personal tools and ornaments of
the deceased. In all, 237 graves were opened
during the three months devoted to the work,
in which quantities of pottery vessels of vari-
ous forms and with a great range of decora-
tive painting, were uncovered. Among burials
of the third type mentioned were several skel-
etons of members of the Zuni Priesthood of
the Bow, with their war paraphernalia, in-
cluding bows and arrows, sacred paint, war
clubs, and their personal or ceremonial be-
longings.
A Franciscan mission was established at
Hawikuh in 1639 and continued in operation
until 1670 when the pueblo was abandoned on
account of Apache depredations. Considering
the length of time since the village was for-
saken by its inhabitants, the remains were in
a remarkably good state of preservation. The
deposit of great quantities of food in the
graves, especially boiled corn on the cob, had
the effect of decaying the bones but of pre-
serving the materials that usually more read-
ily perish, such as baskets, fabries, and ob-
jects of wood, many of which were saved by
immediate treatment. Many very beautiful
things found in association with the remains
include 8 objects of turquoise mosaic, consist-
ing of ornamental hair combs, ear pendants,
and hair ornaments, some of which are so
well executed as to be among the finest ex-
amples of encrusted turquoise ever found in
America, and far exceeding the mosaic work
of the Hopi Indians in Arizona to-day. Of
the fabrics various examples were recovered,
and indeed in one instance the clothing of a
woman was so well preserved that it was pos-
sible to study the character of her dress from
neck to feet.
The pottery of the Hawikuh people, as
mentioned, possesses a wide range of decora-
tion and coloring. Most of the designs are
geometric, but numerous highly conventional-
ized figures of birds, as well as many lifelike
forms of quadrupeds, the eagle, the butterfly,
the tadpole, and the corn plant were found.
Many of the vessels are decorated with a dis-
tinct glaze, black and green predominating.
The vessels consist chiefly of bowls, ranging
NoveMBER 30, 1917]
in size from tiny toy affairs to some as large
as fifteen inches in diameter; but there are
also large and small water jars, and black,
undecorated cooking pots, duck-shaped ves-
sels, and the like.
The finds include, among others, the cere-
monial paraphernalia of a medicine man, com-
prising his medicines; a turkey’s egg con-
taining the bones of the embryo and accom-
panied with a food bowl; several skeletons of
eagles, turkeys, and dogs that had been cere-
monially buried, and deposits of pottery that
had been broken in sacrifice and deposited in
the cemetery not as burial accompaniments.
It was the custom of the Zunis of Hawikuh
to “kill” all the vessels deposited with their
dead by throwing them into the graves, and
this was likewise the case with other house-
hold utensils such as metates and manos used
in grinding corn. Some of the vessels escaped
injury, while all of the fragments of the
broken ones were carefully gathered and will
be repaired.
The site of Hawikuh covers an area of
about 750 by 850 feet, so that only a com-
paratively small part of the site was exca-
vated during this season. The refuse was
found to attain a depth of 144 feet in the
western slope and it will probably be found
to reach a depth of at least 18 feet before the
walls of the summit of the elevation are
reached. An interesting discovery consists
of the remains of many walls entirely beneath
this great deposit of refuse, showing that the
site was occupied in prehistoric times long
before Hawikuh itself was built.
PROGRESS IN COMBATING HOOKWORM
THE recently published annual report of
the Rockefeller Foundation records the re-
sults of intensive work on the study and con-
trol of hookworm and malaria. The report
as quoted in the Boston Medical and Surgical
Journal states that during the year 1916
the work of the International Health Board
continued to be directed chiefly toward the
relief and control of hookworm disease. In
cooperation with the government, systematic
efforts toward control have now been inaugu-
SCIENCE
533
rated in eight of the Southern states and in
fifteen foreign countries, located between de-
grees of latitude 36 north and 30 south in
the tropical and sub-tropical belt, which is
the native habitat of the hookworm. New
fields of operations in 1916 were Salvador,
Brazil, Ceylon, and Siam. Arrangements
were also completed to start work early in
1917 in the Fiji Islands, in Papua, and in
Queensland, Australia.
In British Honduras and the island of
Barbados, preliminary infection surveys were
made, and in the Yangtsekiang valley of Cen-
tral China a preliminary survey was carried
out with special reference to the problem of
soil pollution in shallow mining operations.
The board conducted during the year a
series of four experiments in malaria control.
Three were finished. The fourth will be com-
pleted in 1917. The object of all four experi-
ments was to determine the degree to which
malaria could be controlled within the limits
of reasonable expenditure and under condi-
tions prevailing in typical farm communities
of the South. Gratifying results have been
obtained.
Two commissions were sent to South Amer-
ica. One, composed of six sanitarians, with
Maj.-Gen. William ©. Gorgas as chairman,
visited the republics of Ecuador, Peru, Co-
lombia, Venezuela and Brazil, to study yellow
fever conditions. Two definite objects were
sought: (1) to determine the status of doubt-
ful endemic centers of infection; (2) to as-
certain what measures were necessary and
feasible to eradicate the disease from the lo-
ealities responsible for its dissemination.
The second commission investigated medical
education and public health agencies in Bra-
zil.
Active measures to control and prevent
hookworm disease are now-in operation in
Kentucky, Louisiana, ~ Mississippi, North
Carolina, South Carolina, Tennessee, Texas
and Virginia; in Antigua, Grenada. St.
Lucia, St. Vincent and Trinidad of the West
Indies; in British Guiana and Dutch Guiana;
in Costa Rica, Guatemala, Nicaragua, Pan-
ama and Salvador of Central America; in
5084
Brazil, and in Ceylon and Siam of the Far
East.
Four experiments in malaria control were
carried out during 1916 at different points in
the Lower Mississippi River Valley. In each
a different line of investigation was pursued,
the object being to discover a practical method
of control which the average rural community
could afford.
An experiment was conducted under the
administration of the Mississippi Department
of Health, with Dr. W. S. Leathers as ad-
ministrative director and Dr. C. C. Bass of
Tulane University as scientific director. The
practicability of control through detecting the
carriers and freeing them of the malaria par-
asites was tested. The experiment covered
925 square miles of territory, the size of the
communities varying from nine to sixteen
square miles, with an average population of
1,000. Adjoining communities were taken
up, one after another, as facilities permitted,
the work in each lasting about four weeks
with subsequent visits to insure thorough-
ness. Blood tests were taken, quinine treat-
ment was given to those found infected. The
experiment will be continued in 1917.
THE BRITISH COMMITTEE FOR SCIENTIFIC
AND INDUSTRIAL RESEARCH
THE second annual report of the Commit-
tee of the Privy Council for Scientific and
Industrial Research for the year 1916-17 has
been published. According to an article in
Nature it consists of an introductory state-
ment by Lord Curzon, as lord president of
the privy council, the report of the Advisory
Council, signed by Sir William McCormick
and Sir Frank Health, and appendices giving
orders in council, terms of the imperial trust,
documents relating to research associations,
and names of members of committees at-
tached to the department of scientific and
industrial research. Lord Curzon points out
in his introduction that the foundation of the
department led to the creation of the im-
perial trust for the encouragement of scien-
tific and industrial research.
The trust holds on behalf of the depart-
ment the sum of one million sterling which
SCIENCE -
[N. 8. Vou. XLVI. No. 1196
Parliament has voted for the purposes of the
department. The negotiations of the ad-
visory council with the leading manufacturers
in the various industries showed that it would
not be possible to develop systematic research
on a large scale unless the government were
in the position to assist financially over an
agreed period of years. These considerations
led the government to place a fund at the
disposal of the privy council committee to be
spent over a period of five or six years af-
forded the best means of dealing with the
problem. During the past year negotiations
have been concluded with the Royal Society
for the transfer of the property of the Na-
tional Physical Laboratory, together with the
responsibility for its maintenance and deyvel-
opment, to the department of scientific and
industrial research. The scientific manage-
ment of the laboratory will remain in the
hands of the executive committee under the
chairmanship of Lord Rayleigh, a member of
the advisory council.
The committee reported last year that
grants had been approved to a number of in-
dividual students and research workers for
the year 1916-17 to an amount not exceeding
60001. The amount actually expended under
this head, however, was not more than 35501.
upon thirty-six workers. Throughout the
work has suffered in amount owing to the
war, and the committee was unable to expend
more than 14,524]. out of the 40,0001. placed
at its disposal by Parliament for the financial
year 1916-17. During the current year a
sum of 38,0507. was taken in the estimates,
in addition to the fund of a million referred
to already. The annual vote is intended to
cover (a) the cost of those researches which
will not be undertaken by the proposed re-
search associations; (6) the grants to indi-
vidual research workers, both students and
others; and (c) the cost of administration.
The report says:
The one question of policy, to which throughout
the year we have continuously devoted our atten-
tion, is the working out, with all the care and ad-
vice we have been able to command, of the policy
of cooperative industrial research foreshadowed
in our last report. Lord Crewe, who was at that
NovEMBER 30, 1917]
time lord president of the privy council, received a
deputation of the board of scientifie societies on
December 1 last, at which he outlined the policy
of the government in regard to industrial re-
search. He announced their intention to ask par-
liament to place a large fund—a million sterling
—at the disposal of the department to enable it to
cooperate with the industries of the country in the
foundation and maintenance of approved associa-
tions for research during the next five years or so.
After these initial years it is expected that the
larger industries, at any rate, will be able and
willing to earry on the work of the associations
without assistance. The intention of the govern-
ment is to make a contribution to the assured in-
come of such associations from the subscriptions of
their members, varying in amount according to
circumstances, and with a normal maximum of
pound for pound, though in very exceptional cases
this limit may be exceeded. Lord Crewe also an-
nounced that the board of inland revenue would be
prepared to instruct surveyors of taxes to allow
as a working expense for income-tax purposes the
contributions by traders to industrial associations
formed for the purpose of scientific research for
the benefit of the various trades. The allowance
would be subject to certain conditions; that is to
say, the association must be under government
supervision and the trader’s contribution must be
‘fan out and out payment, made from his trade
profits and giving him no proprietary interest in
the property of the association.’’ Since this de-
cision includes war profits and excess profits taxes,
it offers a considerable inducement to firms af-
fected by these taxes to act promptly.
A TRIBUTE TO PROFESSOR CHURCH
THE College of Civil Engineering of Cor-
nell University paid a tribute of affection and
respect to the emeritus professor of applied
mechanics and hydraulics, Irving Porter
Church, ’73, on November 9. Alumni of the
college presented to the university a portrait
of Professor Church and the sum of $2,500
in Liberty Bonds to form the Irving P.
Church Fund, the income of which is to be
devoted to the purchase of additions to the
library of the college.
According to the Cornell Alumni News, a
simple ceremony of presentation took place
at noon in the auditorium of Goldwin Smith
Hall. Among the persons assembled were
Mr. White and Professors Law, Hewett, Com-
SCIENCE
535
stock, and Gage—men whose terms of service
in the faculty are comparable in length to
that of Professor Church; Mrs. Orandall; the
members of the faculty of civil engineering,
and a number of other professors.
On the rostrum, veiled, was the portrait
lately completed by J. Campbell Phillips.
Dean Haskell expressed the pleasure of the
faculty of civil engineering in taking part in
.this tribute to a beloved teacher, and intro-
duced William D. Kelley, ’80, the representa-
tive of the alumni committee which the Cor-
nell Society of Civil Engineers had appointed
to provide the double memorial. Mr. Kelley
gracefully expressed the affection of the old
students for Professor Church and their sense
of his great services to the college and to
engineering science during so many years.
The contributions to this testimonial, he said,
had come from Cornell engineers in all parts
of the world. He unveiled the portrait and
presented it to the university. Then he took
from his pocket the Liberty Bonds constitut-
ing the Church Fund and handed them to
President Schurman.
The President accepted the gifts in behalf
of the university. He congratulated the
alumni of the College of Civil Engineering on
the value of their testimonial and still more
on the propriety of their gift. What other
offering, he asked, could be more grateful to
a teacher than this double memorial? The
whole university, he said, would be forever
in debt to Professor Church’s character and
scholarship.
[Everybody arose as Professor Church ad-
vanced to the front of the platform. He
apologized for his presence there. What need
for him to talk, he said, when a speaking like-
ness was there to represent him. He accepted
gratefully the tribute of his old students, and
spoke for a few minutes of his reminiscences
of the forty-eight years he had spent at
Cornell.
The board of trustees next day adopted
this resolution: “ First, that the communica-
tion of Mr. F. W. Scheidenhelm, chairman
of the committee, be spread on the minutes
of this board; secondly, that the sincere
536
‘thanks of the Trustees be tendered to the
committee in charge and to all the Cornell
men who have contributed to the gift for this
admirable and appropriate tribute to Pro-
fessor Church; and, thirdly, that it be re-
ferred to the dean of the college of civil
engineering to hang the portrait in a suitable
place.”

THE CHEMICAL BASIS OF AXIAL
POLARITY IN REGENERA-
TION
I
WHEN a piece of a stem is cut out from
a plant one or more new shoots will usually
arise at the apical, and roots at the basal
end of the piece. This phenomenon of axial
polarity was explained by the older botan-
ists as being due to a flow of shoot-forming
substances to the apex and of root-forming
substances to the base. The gathering of
these substances at opposite ends of the
piece was believed to be responsible for the
phenomenon of polarity in regeneration.
While this may or may not be correct, the
writer has recently found facts which sug-
gest an additional or a different mechanism
for this polarity, namely, that the apical
bud suppresses the growth of the buds situ-
ated more basally in the stem by sending
out inhibitory substances in a basal direec-
tion.
The experiments were made on Bryo-
phyllum calycinum. Each node of the
stem of this plant has two leaves in an oppo-
site position, and in the axil of each leaf is
found a dormant bud capable of giving rise
to ashoot. The line connecting two buds of
one node is at right angles to the line con-
necting the two buds of the next node.
Experiment I—A piece of stem, contain-
ing six or more nodes, is eut out from a
plant, all the leaves are removed and the
piece is put into a horizontal position with
the line connecting the two buds of the
most apical node vertical. In this ease
both buds in the apical node may begin to
grow, but as a rule only the upper bud will
continue to grow, while the growth of the
lower bud will soon stop altogether or will

be considerably retarded. None of the
buds in the other nodes will grow out.
Roots will grow chiefly on the under side
of the stem, but in the last node and at the
cut end they may form on the upper side as
well as on the lower side of the stem.
Experiment II. is the same as Experi-
ment I., except that the upper apical bud
is cut out. In this case the lower apical
bud will grow rapidly, but in addition one
or both of the buds of the node next to the
apical will grow out. These buds never
grow out when the upper apical bud is pre-
served and healthy.
Experiment III. is the same as the pre-
vious experiment except that the lower
apical bud is removed, while the upper one
is preserved. In this case, the upper apical
bud will grow out, but none of the others.
It follows from these experiments that the
upper apical bud inhibits or retards the
growth of the lower apical bud as well as
that of the rest of the buds; while the
lower apical bud can not suppress the
growth of the buds in the node behind.
The writer has repeated these experiments
in many modifications, among which those
on longitudinally split stems are the most
striking. The results were uniform.
All these observations are intelligible if
we assume that a bud when it begins to
grow produces and sends out inhibitory
substances toward the base of the stem.
These substances flow in the conducting
vessels in the same half of the stem where
the bud lies; when one apical bud is above
and one below, the two buds in the next
node are in a lateral position between the
upper and lower half of the stem. Hence
the inhibitory substances sent out by the
upper apical bud can reach the two buds
in the next node behind and inhibit their
growth, since these buds lie directly below
or on the lower level of the conducting ves-
sels from the upper apical bud; while in-
hibitory substances sent out by the lower
SCIENCE
[N. 8. Vou. XLVI. No. 1197
apical bud can not reach the buds in the
node behind in large quantity, since these
buds are on the upper level or slightly
above these conducting vessels. When the
two lateral buds grow out they will inhibit
the growth of all the buds behind, each bud
covering a territory of one half stem.
The alternative hypothesis assumes that
since the apical bud is the first to grow out
it will absorb all the shoot-forming ma-
terial.1. If we assume that the shoot-form-
ing material has a tendency to rise this
hypothesis may explain the facts also. But
the following experiment, which seems
erucial, decides in favor of the other as-
sumption. 5
A piece of stem containing a number of
nodes is suspended horizontally, as in the
previous experiments, with the two apical
buds in a vertical line. AIl the leaves are
removed with the exception of those at the
apical node. Here the petioles of the leaves
are left attached to the stem, the leaves
having been cut off. The petioles will wilt
in a week or ten days, but until then will
prevent or retard the growth of the apical
buds in their axils. The buds in the next
node will begin to grow out and as soon as
the petioles have fallen off the apical buds
will also begin to grow.
The next step is decisive for testing the
two hypotheses. If the inhibiting effect of
the apical buds on the more basal buds is
due to the fact that the buds which grow
out first attract all the material from the
basal part of the stem, the buds in the node
behind the apical one, which grew out first,
should continue to outstrip in growth the
apical buds which began to grow out later.
But if the inhibiting effect is due to an in-
1This form of inhibition exists apparently in
the leaf where the shoots which grow out first
prevent other notches in the leaf from giving rise
to shoots by absorbing the material needed for
shoot formation. ScieNcE, 1917, XLV., 436;
XLVI., 115; Bot. Gaz., in print.
DECEMBER 7, 1917]
hibitory substance being sent in the direc-
tion toward the base by the growing bud,
the most apical bud should soon outstrip in
growth those situated in the next node be-
hind, although the latter had an earlier
start. For according to this theory, the
most apical buds should be sending sub-
stanees toward the base which inhibit the
growth in the next bud; while the most
apical buds receive no such inhibitory sub-
stances. The results of the experiment are
quite clear. As soon as the petioles at the
apex fall off the axillary buds at the apex
begin to grow out and soon not only out-
strip in size those of the next buds behind
but actually retard or stop the growth of
the latter. This phenomenon seems intel-
ligible only on the assumption that a grow-
ing bud sends out substances toward the
base of the stem which directly inhibit the
growth of the other buds.
Il
If the inhibition of shoot formation is
due to special inhibitory substances it
should be possible to show that the inhibi-
tion varies quantitatively with the mass of
inhibitory substances produced in the
growing bud, or with the mass of the latter.
While the bud is too small for convenient
quantitative experimentation, it can be
carried out satisfactorily with the leaf. In
a former paper the writer had shown that
the leaf of Bryophyllum sends out ma-
terial toward the base of the stem which
favors root formation; and it also seemed
possible that the leaf might send out sub-
stances in a basal direction which inhibit
shoot formation. The sap from the leaf
flows in conducting vessels situated in the
same half of the stem where the leaf is at-
tached.
When we suspend a stem of Bryophyllum
with six or more nodes horizontally, and
remove all the leaves except the two in the
SCIENCE
549
apical node, the stem will form no shoots as
long as the leaves are alive, but an abund-
ance of roots is produced in the stem. The
two leaves, therefore, inhibit all the shoot
formation in the buds situated basally
from the leaf. When we remove one of the
two apical leaves the axillary bud of this
leaf will grow out and it will have the same
inhibiting effect as the leaf in the previous
experiment. We now make the following
experiment.
Twelve long stems from which all leaves
except one of the two apical ones have been
removed are suspended horizontally, and
the free axillary bud opposite the leaf is
also cut out. Six stems are suspended with
the leaf above, six with the leaf below.
There is a striking difference in the two
sets. When the leaf is below, shoots will
develop either in the two lateral buds of
the first node behind the leaf, or on the
upper side of the second node behind the
leaf. When the leaf is above, no shoots will
develop in the next node behind the leaf
but one shoot may grow in the second node
behind the leaf, on the lower side alone.
These shoots will develop more slowly than
those in the stems whose leaf is on the
lower side.
This is exactly the result which we should
expect if the leaf sends out substances in-
hibiting shoot formation toward the base
of the stem. These substances, being iden-
tical with or accompanying the root-form-
ing substances, flow on that side: of the
stem where the leaf is, but have naturally
a tendency to flow downward and not to
flow upward. Hence, when the leaf is be-
low it is possible for shoots to form in some
(about 50 per cent.) of the stems in the
first node behind the leaf, in which case
the buds are on the upper level of the flow-
ing sap; while when the leaf is above it is
impossible for the buds in the first node
behind the leaf to grow because they are
on the lower level of the sap flow from the
500
leaf. The bud on the lower side of the sec-
ond node behind the leaf (when the latter
is on the upper side of the stem) is outside
the sap flow and hence it may develop.
When we work with a large apical leaf
attached to a short stem (the free apical
bud opposite the leaf is always removed in
these experiments) containing only two
nodes behind the leaf, everything is as de-
scribed for long stems. When, however,
the piece of stem behind the leaf is smaller,
containing only one node, no shoot can grow
on this stem even when the leaf is below.
The mass of inhibitory substance sent out
by a large leaf will flood the buds in this
node with inhibiting material. Occasion-
ally a bud starts to grow but stops before
a leaflet has time to unfold. Such a stem
will form an abundance of roots at the
base. If, however, we reduce the size of
the apical leaf by cutting away nine tenths
of its mass, most or practically all the
stems will form shoots in the node behind
the leaf; but roots in such stems either do
not develop at all or only with long delay.
The leaf, therefore, sends substances to
the basal part of the stem which inhibit
shoot formation and favor root formation,
and the mass of these inhibitory substances
decreases with the mass of the leaf, and ap-
parently parallel with the mass of root-
forming substances sent to the base of the
stem.
Another experiment is equally instruc-
tive. We have seen that when long stems
having all but one apical leaf removed
(and the opposite free apical bud also re-
moved) are suspended horizontally, with
the leaf above, no shoot will form on the
upper side of the stem. When we reduce
the size of the leaf sufficiently this inhibi-
tion ceases.
Again the objection might be raised that
the inhibiting effect of the leaf on shoot
formation in the region behind the leaf is
due not to an inhibitory substance being
SCIENCE
[N. 8. Vou. XLVI. No. 1197
sent out by the leaf but by nutritive sub-
stances needed for the growth of shoots
being sent into the leaf by the stem. This
is highly improbable not only on the basis
of our knowledge of these processes but
also on account of the following fact.
When we cut off a leaf without its petiole,
leaving the latter in connection with the
stem, the petiole will dry out and fall off in
a week or less. If, however, the petiole is
detached from the stem but left attached
to a leaf, it will not wilt, but remain fresh
and green as long as the leaf is alive, which
may be many months. This shows that nu-
tritive material is furnished by the leaf to
the stem, and not vice versa.
aang
While these experiments show that the
inhibiting influence of an apical bud on the
erowth of the more basal buds is due to
one or more inhibitory substances being
sent toward the basal end of the stem, the
other main fact of polarity remains unex-
plained; namely, how it happens that the
most apical bud grows out first. The
writer is inclined to offer the following
suggestion: In the normal plant, the sub-
stances inhibiting shoot formation are con-
stantly flowing from the growing region
toward the root of the plant. When we cut
out a piece of stem and remove the leaves
these substances will at first exist in every
node, but will continue to flow toward the
base. Hence the most apical node will be
the first one to be free from these inhibitory
substances and the bud or buds situated
here can now begin to grow out. As soon
as they grow out they will maintain a con-
stant flow of inhibitory substances toward
the base which will suppress the growth of
buds in the more basal part of the stem.
The experiments, therefore, seem to prove
that axial polarity in the regeneration of
a stem is due to the fact that the apical bud
DECEMBER 7, 1917]
(as well as an apical leaf) send out sub-
stances toward the base of a stem which
inhibit the buds from growing out. These
inhibitory substances may be identical with
or may accompany the root-forming hor-
mones. The most apical bud in an excised
piece of stem will grow out first since it
will be the first to be free from these inhib-
itory substances.
In a former paper the writer had pointed
out that a leaf sends out substances, in an
apical direction through the stem, which
favor shoot formation.

SOME COMMENTS ON THE THEORIES
OF THE STRUCTURE OF MATTER}?!
Proressor Lewis in his paper raised the
question of valence. From the point of view
of chemistry, valence has a definite meaning
which can not be overlooked and which
may be emphasized here. The conception
of valence developed from a study of the
regularities observed in the composition of
substances, and is fundamentally purely de-
seriptive. It is a classification which shows
regularities in the capacity of certain atoms
for combination, or for holding a definite
number of atoms or their equivalents in
combination. The continued study of
chemical composition has, as a matter of
course, extended the classification. The
phenomena of oxidation, the ionization of
substances in solution and otherwise, and
similar properties, have brought forward
the view that, choosing a suitable element
or state of an element as the zero or neutral
point, the valence of an element in a given
combination may be denoted either by a

positive number or a negative number.
This view was adopted for individual cases
some time ago by different chemists, but
became of general interest when J. J. Thom-
son, using corpuscles, showed how this could
be pictured readily, and applied in a simple
manner.
A few words may be devoted to the fact
that the classifications given by valence
should involve no considerations of meas-
ures of relative stabilities of substances, al-
though the existence of compounds depends
upon stabilities and rates of decomposition.
Stability discussions should not enter di-
rectly into questions of valence, but unfor-
tunately this fact is often overlooked and
much confusion has resulted.
The question of so-called polar and non-
polar valence is one raised by Professor
Lewis. At the present time the view that
only non-polar bonds exist is probably held
by no chemist. The electron conception of
valence, based upon a study and compari-
son of organic and inorganic compounds,
postulates polar valence only; in other
words, each valence linking is equivalent
to one atom functioning with a negative
charge, and the other atom with a positive
charge. The electrostatic view does not in-
volve at first sight such questions as distri
bution of electrons within the atom, ete.
At the present time there are a number
of chemists who advocate both polar and
non-polar valences, even assuming both to
be present in a molecule at the same time. —
The reasons for assuming the existence of
non-polar valences appear to be negative
ones. If direct evidence is lacking, or if
ignorance is manifested with regard to the
reactions of certain groups, or if these
groups do not take part in the desired re-
action with sufficient velocity, the existence
of polar valences is denied. A strong argu-
ment in favor of assuming polar valences
in organic compounds is, that if they are
502
not assumed, two different types of oxida-
tion reactions become necessary, and these
two types would be contradictory. This
was pointed out several years ago.”
Direct evidence for the polar nature of
valences involved in the Grignard reactions
is given by some recent experiments.*
Without going into details, these results
may be quoted.

These results are of the greatest signifi-
cance with regard to the question of polar
and non-polar valence and indicate that the
valence or linkings of organic compounds
are of the same character as those of inor-
ganic compounds. They bear out the ex-
planation of the Grignard reaction on the
basis of the electron conception of valence
published several years ago, and in addi-
tion will unquestionably throw light on the
processes operating in solutions, aqueous
and otherwise.
With regard to Professor Jones’s work
on electromerism, some interesting develop-
ments may be presented. As we under-
stand the term, electromerism means elec-
tronic tautomerism and includes substances
structurally identical, but mutually trans-
formable by an exchange of negative elec-
trons between atoms composing the mole-

ecules. Thus ammonium nitrate, NH,NO,,
and hydroxylamine nitrite, NH,OH NO,,
while mutually transformable by a suitable
exchange of negative electrons, since as far
as the charges on the atoms are concerned
they differ only in the valence of the ni-
trate and nitrite nitrogen atoms, are not
structurally identical and would not, there-
fore, be classed as electromers.
Professor Jones in his paper considered
electromeric nitrogen compounds. In elec-
tromers, the states of oxidation of certain
atoms in the structural isomers are differ-
ent. A number of years ago we showed
that the explanation of the isomerism of a
number of structurally identical organic
compounds may be referred to the state of
oxidation or the valence of certain atoms.
The compounds referred to are generally
known as geometrical or cis-trans isomers.
Direct evidence based upon the ionization
constants of organic acids‘ showed that the
isomerism of maleic and fumaric acids is
due to phenomena now included under
electromerism while addition reactions of
unsaturated carbon compounds lead to
similar conclusions.® The evidence in de-
tail is given in the published papers and
need not be repeated here. It is possible
to go somewhat farther. Werner and
Pfeiffer? have placed in parallel the so-
called geometrical isomerism of double
bonded carbon atoms and the isomerism due
to plane configuration of certain cobalt,
chromium and platinum compounds:

DECEMBER 7, 1917]
Whatever explanation is accepted for
the double bond isomerism, the same expla-
nation will apply to the isomerism of the
platinum compounds. Werner considers
that the explanation of the spatial configu-
ration applies to both. On the other hand,
if the double bond isomerism is due to the
directions of the valences which is the
same as the distribution of the negative
electrons in the acids, then the explanation
of the isomerism of the platinum com-
pounds should be based upon the distribu-
tion of the electrons in the platinum atom.
There is, however, only one atom involved
here, so that it appears as if this isomerism
would furnish a method for showing the
distribution or arrangement of the electrons
in an atom, or perhaps the spatial configu-
ration of the atom, different arrangements
of electrons giving rise to possibilities of
the existence of isomeric compounds. It is
even possible, and perhaps very probable,
that the different arrangements of the elec-
trons might control the spatial positions of
the combined groups. The spatial configu-
rations deduced by Werner and others, then
would exist, but would actually be an effect
of the arrangement of the electrons. The
positions of the combined atoms therefore
would be a result of the isomerism and not
its cause.
These platinum and similar metal com-
pounds would then belong to the class of
electromeric substances. Since this expla-
nation means that the spatial arrangement
of atoms or groups around a central atom
depends primarily upon the spatial ar-
rangement of the valence and also other
electrons of that central atom, a further
logical deduction would inelude all optically
active isomers in organic and inorganic
chemistry in the group of electromers. The
spatial arrangements of the atoms or groups
here would also be governed or controlled
primarily by the arrangement of the elec-

POSSIBILITY OF USING GRAVITY
ANOMALIES IN THE SEARCH
FOR SALT-DOME OIL AND
GAS POOLS
THE immense masses of common salt that
have foreed their way up toward the surface of
the earth in Louisiana, Texas and other low
plains regions where there is no hard rock
within several thousand feet of the surface,
seem to afford all the fascination and baffling
questions that can be desired by the structural
geologist, though thrilling encounters with
such questions are usually sought in moun-
tainous regions. Recorded and available notes
on experiences in the sinking of the thousands
of wells that have been put down on salt domes
in the search for oil is dishearteningly scant,
and yet sufficient to give a fair idea of the
common extents, positions and shapes of the
upper portions of the salt cores. If as much
were known concerning their lower portions it
might not only be possible to determine their
cause and mode of growth with a fair degree
of certainty, but to devise means of discover-
ing by gravity observations, hidden domes, for
some are scarcely evident from the surface,
and perhaps many unsuspected ones with val-
uable oil and gas pools are scattered through
the coastal portions of Louisiana, Texas and
other regions.
Are the salt domes due to some process re-
lated to voleanic action? The domed form of
the strata, which is much more commonly seen
than the core itself, is such as might have been
produced by a rising plug of igneous rock and
even the masses of salt and associated second-
ary deposits might apparently have been pro-
duced indirectly by intrusions. On the other
hand, though many very deep wells have been
drilled in salt domes, igneous rock has rarely
if ever been touched. Since there are numer-
ous varieties of salt domes—some making a
504
conspicuous hill, some through recent solu-
tion of the salt making a depression, and some
having little or no effect on the surface, the
salt core of some lying at slight depth and of
others at great depth—it would appear that if
they are due to intrusion, the igneous rock
should have been found in some of them.
Furthermore, in areas of igneous activity in-
trusions have various forms, dikes being com-
mon, but salt domes are sharply localized,
more or less equi-dimensional laterally, in
length and breadth rarely measuring over two
or three miles or less than one half mile.

THE CARNEGIE INSTITUTION AND»
THE PUBLIC}! %
RECIPROCITY or P gbATions
Im 1s ore Oey asserted and more
often Lace ASSureed that an endowed al-
Artatte o¥ganization actiiag under a state
oY a national charter may proceed without
restriciions in the development of its work.
This, in accordance with this view, the in-
stitution is frequently congratulated on its
supposed freedom from governmental con-
trol and on its supposed immunity from
social restraint. But this view is neither
consonant with fact nor consistent with
sound public policy. All such organiza-
tions are properly subject not only to the
literal constraints of their charters but
also to the commonly more narrow though
unwritten limitations imposed by contem-
porary opinion. The ideal to be sought by
them in any tase consists in a reciprocity:
of relations between the individual endow-
ment on the one hand and the vastly larger
and more influential public on the other
hand. This. ideal, however, like most:
idéals, is rarely fully attainable. Its. exist-
énce and importance are, indeed, almost as.
rarely recognized. Hence, any new altru-
istic organization is apt to find itself oscil:
lating between two extreme dangers: the:
one arising from action on the part of the
organization prejudicial] to public inter-
ests; the other arising from public expec-.
tations impossible of attainment and there-.
fore prejudicial to_the organization.
Happily for the institution, neither of ©
these extreme dangers has been. seriously

encountered. Its evolution has proceeded
without surpassing charter limitations and
without permanent hindrance from an ag-
eregate of expectations certainly quite un-
paralleled in the history of research estab-
lishments. But while thus far it has been
practicable to steer clear of the rocks and
the shoals toward which enthusiastic
friends even of the institution would have
it head, and to demonstrate the inappro-
priateness, the futility, or the impossibil-
ity of a large number of recurring sugges-
tions for application of the institution’s in-
come, there remains a multitude of sub-
jects and objects of omnipresent impor-
tunity for which the institution has fur-
nished and apparently can furnish only
general disappointment. Some references
have been made occasionally in previous
reports to these matters, but in general
they have been ignored for the reason that
they tend to waste energy in the produc-
tion of nothing better than heat of con-
troversy. A full enumeration and discus-
sion of them would require nothing short
of a volume, which would be of value prob-
ably only to our successors. There are two
classes of them, however, presenting widely
different aspects, which appear worthy of
special mention in this connection and at
the present unusual epoch in the intellec-
tual development of mankind. These two
classes find expression respectively in the
perennial pleas of humanists for a larger
share of the institution’s income and in the
more persistently perennial pleas of aber-
rant types of mind for special privileges
not asked for, and not expected by, the
normal devotees to learning.
CLAIMS OF HUMANISTS
Whenever and wherever the rules of
arithmetic are ignored, then and there will
develop vagaries, misunderstandings, and
errors of fact that only the slow processes
SCIENCE
[N. 8. Vou. XLVI. No. 1198
of time can correct. Hence it was not
simply natural but necessary that in the
evolution of the institution something like
conflict surpassing the bounds of generous
rivalry should arise between claimants
whose aggregate of demands for applica-
tion of income has constantly exceeded the
endowment from which income is derived.
Indeed, if the evidences of experience are
to be trusted, there is scarcely a province
in the world of abstract and in the world
of applied knowledge which has regarded
its needs as incommensurable with that en-
tire income. It was an inevitable conse-
quence, therefore, of inexorable conditions
that a majority of the commendably en-
thusiastic workers in these numerous proy-
inces should fail to get from the institution
all the aid they desired. It was a similarly
inevitable consequence of those conditions
that some of these enthusiastic workers
should attribute their disappointment to
wrong causes. And it might likewise have
been predicted with certainty that the
largest share of the resulting disapproba-
tion visited upon the institution should
come from the province of the humanists, .
not because they possess any property of
superiority, of inferiority, or any other sin-
gularity, but, firstly, for the reason that
they are more numerous in the aggregate
than the devotees of all other provinces
combined; and, secondly, for the less ob-
vious but more important reason that the
subjects and objects of their province are
more numerous, more varied, more com-
plex, and in general less well defined than
the subjects and objects of any other proy-
ince.
Concerning all these matters humanistic
which have agitated academic circles es- -
pecially for centuries, the administrative
office of the institution is naturally called
upon to share in an extensive cérrespond-
ence. Some of this is edifying, most of it
DrcEMBER 14, 1917]
is instructive, but a large if not the greater
part of it appears to have been relatively
fruitless in comparison with the time and
the effort consumed. Why is this so? Or,
is it only apparently and not actually so?
May it not be due to the proverbially nar-
row, or possibly ‘‘materialistic,’’ tenden-
cies sometimes attributed to administrative
officers? Much attention has been given
to these inquiries with a view to securing
answers free from personal bias and inde-
pendent of administrative or other ephem-
eral restrictions. Essentially correct an-
swers are furnished, it is believed, by the
voluminous correspondence referred to,
since it has supplied the data required for
application of the objective methods of ob-
servation and experiment as well as the
data for application of the subjective
methods of a priori reasoning and _his-
torico-eritical congruity.
An appeal to that correspondence shows,
in the first place, that there is no con-
sensus of opinion amongst professed human-
ists as to what the humanities are. It is
well known, of course, by those who have
taken the trouble to reflect a little, that
the words humanistic and humanist are
highly technical terms, more so, for ex-
ample, than the term ‘‘moment of iner-
tia,’? the full mechanical and _ historical
significance of which can only be under-
stood by consulting Euler’s ‘‘Theoria
Motus Corporum Solidorum.’’ Technic-
ally, the humanist is not necessarily hu-
mane, though fortunately for the rest of
us he generally possesses this admirable .
quality ; he needs only to be human. The
distinction is well illustrated at one ex-
treme by what Greg called the ‘‘false mo-
rality of lady novelists,’’? which could
doubtless be surpassed by the falser mo-
rality of male authors of fiction; and at
another extreme by the merciful réle of the
physician in saving lives, or the equally
SCIENCE
575
merciful réle of the engineer who builds
bridges that will not fall down and kill
folks, whose works, nevertheless, are often
relegated by the humanist to the limbo of
technology.
But these finer shades of verbal distine-
tion which, with more or less elaboration,
have come down to plague us from the
days of the illustrious Aleuin and Eras-
mus, but with no such intent on their part,
are less disconcerting than other revela-
tions supplied by this expert testimony. It
shows, in the second place, the surprising
fact that some few humanists would re-
strict this field of endeavor to literature
alone. From this minimum minimorum of
content the estimates of our esteemed cor-
respondents vary with many fluctuations
all the way up to a maximum maximorum
which would embrace all that is included
in the comprehensive definition of anthro-
pology to be found in the Standard Dic-
tionary. Thus some eminent authorities
would exclude from the humanities all of
the ancient classics even, except their lit-
eratures. To such devotees philology, lit-
erary or comparative, has no interest;
while archeology, classical or cosmopoli-
tan, is of no more concern to them than
comparative anatomy, which latter, by the
way, is held in certain quarters to com-
prise the whole of anthropology. Equally
confident groups of enthusiasts, on the
other hand, animated by visions held es-
sential to prevent our race from perishing,
would, each in its own way, have the in-
stitution set up boundaries to knowledge
within which the humanities, as always
hitherto, would play the dominant part
but whose appropriateness of fixation
would be immediately disputed by other
groups. There would be, in fact, only one
point of agreement between them, namely,
that the institution’s income is none too
large to meet the needs of any group. It
576
should be observed in passing, however,
in fairness to our friends the humanists,
that they are not alone in their regressive
efforts to establish metes and bounds for ad-
vancing knowledge. Contemporary scien-
tists have likewise pursued the same ignis
fatuus with similarly futile results, as is
best shown by the arbitrary and often
thought-tight compartments into which
science is divided by academies and royal
societies. A sense of humor leads us to
conclude that these likenesses between
groups and assemblages thereof, still more
or less hostile at times to one another, serve
well to prove that the individuals con-
cerned are human if not humanistic and
that they all belong to the same genus if
not to the same species.
In the third place, there is included in
the extensive correspondence on which this
section is mainly based a special contri-
bution of letters furnished mostly by uni-
versity presidents and professors and by
men of letters selected with a view to ex-
cluding all those who might be suspected
of any non-humanistic predilections.
These letters were received as replies to a
communication issued first during the
year 1910, and occasionally since then, so-
liciting counsel from those well qualified
to assist the institution in determining
how it may best promote research and
progress in the humanities and how it may
be relieved of the charge of unfairness to-
ward them-in the allotment of its income.
The essential paragraphs in this communi-
cation are the following:
Amongst other suggestions arising naturally in
this inquiry -is that of the desirability of some-
thing like a working definition of the term hu-
manities. To the question What are the humani-
ties? one finds a variety of answers, some of which
seem much narrower than desirable.
In order to get additional information on this
subject and in order to make this part of the in-
quiry as concrete and definite as possible, I am

sending copies of the inclosed list of publications
to a number of friends requesting them to mark
those entries of the list which they, as individuals,
would consider works falling properly in the
fields of the humanities. I shall esteem it a great
favor, therefore, if you will kindly examine this
list, indicating by some sort of check-mark what
works, if any, may be rightly so classed, and then
mail the same in the inclosed stamped envelope.
It will be of service also, to indicate to me, if you
care to do so, the lines of distinction which may
be drawn between the humanistic sciences and the
physical sciences. I am sure you will agree with
me that it will be a decided aid to all of us to se-
cure something like common definitions for these
boundaries of knowledge.
About thirty distinguished authors have
participated in this symposium; and their
frank and generous expressions of opin-
ion would be well worthy of publication
if they had not been assured that their re-
sponses would not be used for such a pur-
pose. The identities and details of their
letters must therefore be retained, for the
present at any rate, in the archives of the
institution. But since many of them have
offered to relieve the solicitor of this ob-
ligation, and probably all of them would
do so on request, it is believed that no
confidence will be violated in stating the
two following statistical facts, which not
only agree with one another but strongly
confirm also the inductions referred to
above, drawn from the more miscellaneous
correspondence of the institution:
1. The definitions of the term humani-
ties vary from the exclusiveness of litera-
ture alone to the inclusiveness of the more
recent definitions of anthropology, with a
noteworthy tendency toward inclusiveness
rather than the reverse.
2. To the concrete question What works,
if any, already published by the institution
fall in the humanities, the answers vary
from 2 to 33, the number of publications
up to 1910 being 146.
The correspondent who assigned the
DECEMBER 14, 1917]
largest number of publications to the hu-
manities took the trouble also to count up
the totals of the numbers of pages of all
the works issued by the institution up to
that time. His count gave: for the hu-
manities, 10,813 pages; for all other
branches of knowledge, 21,700 pages.
In connection with these statistical data,
it is appropriate to add the corresponding
figures for the publications of the institu-
tion brought down to date, namely, Oc-
tober, 1917. In deriving these there are
ineluded under the humanities works in
archaeology, folk-lore, international law,
history, literature, and philology. Of a
total of 88 volumes, 58 octavos contain
19,921 pages and 30 quartos contain 10,718
pages, the total number of pages being
30,639; but four of the volumes are still
in press and their pagination is not in-
eluded.
Since the total number of pages of
printed matter issued by the institution up
to date is 98,565, it appears that the shares,
if such a term may be used, allotted to
the humanities and to all other fields of
learning combined are in round numbers
one third and two thirds respectively.
Whether this is one of fairness and fitness
will doubtless remain for a long time a dis-
puted question, since it seems to be one to
which the dictum of Marcus Aurelius ap-
plies with peculiar emphasis. In the mean-
time, while waiting for a diminution in
the diversity of opinion which calls that
dictum to mind, it appears to be the duty
of the institution to proceed, as it has
sought to proceed hitherto, in a spirit of
sympathy and equity based on merit to-
wards all domains of knowledge, with a
full appreciation of the necessary limita-
tions of any single organization and with
a respectful but untrammeled regard for
the views, the sentiments, and the suffrages
of our contemporaries.
SCIENCE
577
ABERRANT TYPES OF MIND
If words and phrases drawn out of the
past may obscure thought and supplant
reason in the domains of the less highly
developed sciences, like the humanities, for
example, they are by no means free from
difficulties when used as media for the com-
munication of ideas in the domains of the
more highly developed sciences. The dif-
ferences between the ambiguities and the
obseurities of the two domains are mainly
in degree rather than in kind. It is a
truism, of course, that in general it is much
easier to discover errors and to improve
uncertain verbal expression in the definite
than in the indefinite sciences. Erroneous
statements and interpretations of fact may
be often corrected by the facts themselves
or by means of a knowledge of their rela-
tions to underlying principles. Precision
and correctness of language are also
greatly increased in any department of
learning when it becomes susceptible to
the economy of thought and of expression
characteristic of the mathematico-physical
sciences. The perfection of these latter is,
indeed, so great that novices working in
them are often carried safely over hazar-
dous ground to sound conclusions without
adequate apprehension of the principles in-
volved and with only erroneous verbal
terms at command to designate the facts
and the phenomena considered.
Nevertheless, it must be admitted that
the terminology of what commonly passes
for science as well as the terminology used
frequently even by eminent men of science
is sadly in need of reformation in the in-
terests of clear thinking and hence of un-
equivocal popular and technical exposi-
tion. To realize the vagueness and the in-
appropriateness in much of the current
use of this terminology one needs only to
examine the voluminous literature avail-
able in almost any subject called scientific.
578
It is so much easier to appear to write well,
or even brilliantly, than it is to think
clearly, that facile expression is often mis-
taken for sound thought. Thus, to illus-
trate, while in physics the terms force,
power and energy have acquired technical
meanings entirely distinct and free from
ambiguity, they are commonly used as
synonyms, and quite too commonly to
designate properties, sentiments, and in-
fluences to which their application is mean-
ingless. The ‘‘forces,’’ the ‘‘powers,’’ and
more recently, the ‘‘energies’’ of ‘‘nature”’
are frequently appealed to in popular lit-
erature; and a familiar bathos consists in
equipping them solemnly with the now
vanishing stable furniture ‘‘for the benefit
of mankind.’’ Science is disfigured and
hindered also by much inherited antithet-
ical terminology for which reasons once
existent have now disappeared or are dis-
appearing. Instances are found in such
terms as metaphysics, natural history, and
natural science, the two latter of which ap-
pear to have come down to us without sen-
sible modification, except for a vast in-
crease in content, since the days of Pliny
the Elder. The diversification and the re-
sulting multiplication of meanings of the
terms of science are everywhere becoming
increasingly noticeable and _ confusing.
One of the most recent manifestations is
seen in the phrase ‘‘scientific and indus-
trial research,’’ which probably means
about the same thing as the equally uncer-
tain phrase ‘‘pure and applied science’’;
while both phrases have been turned to ac-
count in setting up invidious distinctions
inimical to the progress of all concerned.
This looseness in the use of terminology
inherited from our predominantly literary
predecessors and the prevailing absence of
any exacting standards of excellence in ex-
position make it easy for that large class
here designated as aberrant types to take
SCIENCE
[N. S. Von. XLVI. No. 1198
an unduly prominent part in the evolution
of any establishment founded for the pro-
motion of “‘research and discovery and the
application of knowledge for the improve-
ment of mankind.’’ These types are nu-
merous and each of them presents all gra-
dations ranging from harmless mental in-
capacity up to aggressive pseudo-science,
which latter often wins popular approval
and thus eclipses the demonstrations of
saner counsels. ‘The representatives of
these types are variously distinguished in
common parlance as cranks, quacks, aliens,
charlatans, mountebanks, ete. Some of the
most persistent types are known as are-
trisectors, circle-squarers and perpetual-mo-
tion men and women. They are not of re-
cent development; they are coextensive
with our race; but they have been little
studied except in the cases of extreme di-
vergency from the normal. One impor-
tant work, however, has been devoted to
the intermediate types of this class with
which the present section of this report is
concerned. This is the profoundly learned
book entitled ‘‘A Budget of Paradoxes,’’2
by Augustus De Morgan, who gave a sur-
prising amount of attention, extending
through several decades, to these people,
whom he ealled ‘‘paradoxers.’’
It ought to be well known, but evidently
is not, that the institution has had to deal
with, and must continue to be harassed by,
great numbers of these aberrant types.
The happy phrase of the founder concern-
ing the ‘‘exceptional man’’ has worked out
very unhappily both for them and for the
institution, since it has only inevitable dis-
appointment to meet their importunate de-
mands, while they in turn have only in-

evitable animadversion to visit finally upon
the institution. Deluded enthusiasts and
designing charlatans entertain alike the il-
lusion that here at last is an establishment
that will enable them to realize their wildest
dreams of fame and fortune. But in the
end the hopes of these people are either
rudely shocked or wrecked, not because the
institution would disturb them in their fan-
cies but because they compel the institution
to decline to approve their theories and to
subsidize their projects. Many individuals
of this class are extraordinarily clever, in
literary capacity especially, although they
are almost all notably deficient in critical
faculties. In the initial stages of corre-
spondence with them they are wont to at-
tribute superhuman qualities to the ad-
ministrative officer concerned, but if he be-
comes at all exacting they are wont to
suggest a speedy degeneracy for him
towards inhuman qualities. The absurd-
ities, the arrogance and the audacity (often
pushed to the extreme of mendacity) of
their claims are generally Iudicrous
enough, but these claims are often founded
also on recondite fallacies which present
pathetic as well as humorous aspects. Two
illustrations drawn from the older and
hence more impersonal sciences may suffice
to indicate the nature of the daily experi-
ence here in question:
1. A teacher of youth in a publie school
desires assistance in securing letters-pat-
ent for a new proof of the Pythagorean
theorem. And why not, since we read
every day in the public press and in the
debates of legislative bodies of ‘‘principles’’
being patented ?
2. Quite recently it has been ‘‘discoy-
ered’’ that the air and the ether contain
«free energy.’’ If this is so, if energy like
urbanity is free, why should it not be rend-
ered available at the expense of the insti-
tution for the improvement of mankind?
SCIENCE
579
Study and reflection concerning these
aberrant types and an intimate association
with them beginning thirty years before
the foundation of the institution, all point
to the conclusion that responsibility for
their undue prominence must be attributed
in large degree and in the last analysis to
a prevalent inadequate development of
critical capacity even amongst the best edu-
cated classes of contemporary life. Many
representatives of these latter regard the
eccentric individual as thereby worthy of
special attention. He is often referred to
as a sprite or as a male witch, but com-
monly, of course, under the more familiar
designations of our day as ‘‘a genius’’ or
as ‘‘a wizard.’’ Thus it is quite easy for
obvious charlatans and ignoramuses, as
well as for those in pursuit of Sisyphean
paralogisms and anachronisms, to secure
letters of introduction and commendation
to the institution from distinguished people,
who pass the applicants along on the
theory apparently that no harm can result
from an effort to assist in the laudable
work of extending learning. It is assumed
that a research establishment must have ef-
fective facilities for utilizing the necro-
mantic capacities attributed to those in
particular to whom the terms genius and
wizard are by common assent applied.
Such introductions and commendations are
generally held to be equivalent to ap-
provals which may not be lightly set aside.
The suggestion of tests of the pretensions
and of checks on the deductions of these
applicants is repulsive to them. What
they desire is not diagnosis but indorse-
ment. In all these matters there is revealed
likewise a widely diffused misapprehen-
sion concerning the meanings of the terms
science and research. The first may mean
anything from occultism to the steam en-
gine or to the telephone and thence up to
those rarely appreciated principles of which
580
the law of conservation of energy is one of
the most conspicuous examples. The other
term has a similarly wide range of mean-
ing, but it stands most commonly either
for a secret process which leads to riches
by way of patent offices or for enterprises
in which the institutton is supposed to act
as a complaisant disbursing agency.
In dealing with these aberrant types
there are encountered certain other fallacies
of a more specious and hence of a more
troublesome character. They arise out of
the prevailing innocence of, if not con-
tempt for, the doctrine of probabilities.
The simplest of these fallacies is seen in
the common belief that one mind is as likely
as another to make discoveries and advances
in the realms of the unknown. Thus it is
assumed that research establishments
should maintain experts, or corps of them,
for the purpose of promoting the efforts of
tyros, amateurs and dilettanti, or, in other
words, perform the functions of elementary
schools. A subtler fallacy is expressed in
the more common belief that a research or-
ganization should occupy itself chiefly in
soliciting and in examining miscellaneous
suggestions. It is held that if these are re-
ceived in large numbers and if they are
read long enough and hard enough, the
possibilities of knowledge will be completely
compassed. This has been elsewhere called
the process of ‘‘casting dragnets in the wide
world of thought ... with the expectation
that out of the vast slimy miscellanies
thus collected there will be found some
precious sediments of truth.’’ It is, in-
deed, a metaphysical method of extracting
truth out of error. The worst of all these
fallacies is found in the not unpopular no-
tion that if experts could be set at work
under the direction of inexperts great
progress could be achieved. This is the
fallacy so often used to justify placing
technical work under the administration of
SCIENCE
[N. 8. Von. XLVI. No. 1198
politicians and promoters rather than
under the charge of competent men. It
finds frequent expression also in sugges-
tions to the institution that its corps of in-
vestigators might avoid the dangers of
“respectable mediocrity’’ by yielding to
the requests of the less conservative and
more brilliant advocates of advancing
knowledge.
But what, it may be asked, are the char-
acteristics which differentiate these pseudo-
scientists from normal investigators?
They are well defined and not numerous.
The pseudo-scientist is in general excess-
ively egoistic, secretive, averse to criticism,
and almost always unaware of the works
of his predecessors and contemporaries in
the same field. He displays little of that
eaution which is born of adequate knowl-
edge. He is lacking especially in capacity
to discover and to correct his own mistakes.
He is forever challenging others to find
errors in his work. He has an overween-
ing confidence often in formal logic, but is
unable to see that this useful device may
play tricks by bringing him, for example,
simultaneously to right and to wrong con-
clusions by reason of wrong premises. His
worst defect is manifested in asking for
and in expecting to get more lenient con-
sideration in the forum of demonstration
than that accorded to his more modest but
more effective competitors.
How inadequate are the hasty popular
estimates of these exceptional individuals
is sufficiently witnessed in the extensive ex-
perience of the institution. In the brief
interval of its existence it has had to deal
with about 12,000 of them. Many of these
have been commended to the institution in
terms well calculated to set aside the laws
of biologic continuity and thus to elevate
the aspirants abruptly from irreproach-
able respectability to questionable fame.
To some of them have been attributed quali-
DECEMBER 14, 1917]
ties worthy of the mythological characteris-
tics conceived by the unrestrained imagi-
nations of men in prescientific times. Not
a few of them have proved to be obvious
fakers, schemers or incompetents masque-
rading in the name of learning with the
confident expectation that the institution
would indorse, finance or otherwise pro-
mote their objects under the guise of re-
search. But, as might have been pre-
dicted, the history of all this varied experi-
ence is a history of futility clouded here
and there by manifestations of the baser
traits‘of mankind and lighted up only ocea-
sionally by flashes of wit, wisdom or humor
in the prevailing pathologie cast.

SCIENTIFIC EVENTS
CONJOINT BOARD OF SCIENTIFIC STUDIES IN
GREAT BRITAIN
Tue first annual report of the Conjoint
Board of Scientific Studies, established at the
instance of the Council of the Royal Society
in June, 1916, has been issued. As reported
in the British Medical Journal, the objects of
the board are to promote the cooperation of
those interested in pure or applied science; to
supply means by which the scientific opinion
of the country on matters relating to science,
industry and education, may find effective ex-
pression; to promote the application of sci-
ence to industries and the service of the na-
tion; and to discuss scientific questions in
which international cooperation seems advis-
able. The chairman of the board, which con-
sists of representatives of numerous societies,
is the president of the Royal Society. Among
the constituent societies are the Royal Anthro-
pological Institute, the Royal Colleges of
Physicians and Surgeons in England, the
Royal Society of Medicine, the Pharma-
ceutical Society of Great Britain, the Psycho-
logical, Linnean, Zoological, Biochemical, and
Psychological Societies, the Institute of Chem-
istry, the Society of Chemical Industry, the
Chemical Society, and the Royal Institute of
British Architects. There is a small execu-

tive committee, of which Sir Joseph J. Thom-
son, president of the Royal Society, is chair-
man, and Dr. W. W. Watts, professor of geol-
ogy in the Imperial College of Science and
Technology, secretary; among the other mem-
bers are Sir Alfred Keogh and Sir Ray Lan-
kester. The board has appointed a number
of sub-committees, some of which appear to
have got to work during the year, including
The International Catalogue Subcommittee
which has obtained information regarding the
extent of the use made by sciéntific men of
the present International Catalogue of Scien-
tific Literature; the Watching Subcommittee
on Education, of which Sir Ray Lankester is
convener, the Metric System Subcommittee,
and the Anthropological Survey Subcommittee.
The last named consists of Major Leonard
Darwin (convener), Professor A. Keith (sec-
retary), Dr. James Galloway, Dr. P. Chalmers
Mitchell, and Professors G. Elliot Smith, Karl
Pearson and Arthur Thomson. It has pre-
sented a report on the need of a physical
survey of the British people, and intends to
institute further inquiries before drafting re-
commendations. On its advice the executive
committee asked the Board of Education, the
Local Government Board, and the Registrar-
General’s Office to nominate representatives on
the subcommittee, and Sir George Newman,
Sir Arthur Newsholme, and Dr. T. H. C.
Stevenson, have been appointed. The Watch-
ing Subcommittee on Education has held a
conference with the Council of Humanistic
Studies, and has made a report to the Conjoint
Board, in the course of which it recommended
that both natural science and literary subjects
should be taught to all pupils below the age of
16, and that afterwards specialization should
be gradual and not complete. It points out
that in many schools of the older type more
time, which can often be obtained by economy
in the time allotted to classics, is needed for
instruction in natural science, but that in
many schools more time is needed for instruc-
tion in languages, history and geography.
The opinion is also expressed that while it is
impossible and undesirable to provide instruc-
tion in both Latin and Greek in all secondary
582
schools, provision should be made in every area
for teaching these subjects. The subcom-
mittee also transmitted to the Government
Committee on Science in the Educational
System of Great Britain two recommenda-
tions on which it was unanimous; one is that
in order to secure teachers able to give inspir-
ing and attractive courses in science adequate
salaries should be paid, and the other, that
while prime importance must be attached to
provision for laboratory work it was essential
that there should be instruction also in the
romance of scientific discovery and its applica-
tions. Every pupil should not only receive
training in observational and experimental sci-
ence, but should be given a view of natural
science as a whole, the object being to evoke
interest in science in relation to ordinary life,
“rather than to impart facts or data of sci-
ence presented by an examination syllabus, or
even to systematize their rediscovery.”
WIRELESS TIME SERVICE IN THE PHILIPPINE
ISLANDS
THE progress in the time service of the
Philippine Islands is made evident from the
fact that since October 1, 1917, the Cavite
Radio Station, cooperating with the Bureau of
Posts and the Manila Observatory, sends out
time signals of the 120th meridian East of
Greenwich at 11 a.m. and 10 p.m. every day,
Sundays and holidays inclusive. Manila
holds an enviable position in the Pacific and
the interests of shipping companies making
Manila a port of call are too prosperous to be
overlooked. Accurate time signals and wise
typhoon warnings are of immense value to
the units of the United States Asiatic Fleet,
to Army transports and in general to oversea
shipping.
For the purpose of sending time signals, the
transmitting clock of the Manila Observatory
is connected with the Cavite wireless station
through the Bureau of Posts. Manila Ob-
servatory time signals begin at 10:55 a.m. and
9:55 p.m., standard time of the 120th meridian
East of Greenwich; and continue for five
minutes. During this interval every tick of
the clock is transmitted, except the 28th, 29th,
54th, 55th, 56th, 57th, 58th and 59th of each

PROFESSOR W. A. NOYES AND THE AMERICAN
CHEMICAL SOCIETY x
ReEsotutTions on the services of Professor
W. A. Noyes to the American Chemical So-
ciety have been passed, as follows:
Wuereas, Dr. William A. Noyes is soon to
terminate his service as editor of the Journal
of the American Chemical Society, to which
for fifteen years he has, with unceasing devo-
tion and conscientious care, given a large por-
tion of his time; and :
Wuereas, During these years he has by his
effective conduct of the Journal raised it to a
scientific publication of the very first rank, in
which is now published by far the greater part
of the best chemical research carried on in
this country, and
WuereEas, He was the leading spirit in the
organization and detailed planning of the
Abstract Journal of the Society, which has
made available to American chemists in an
exceptionally comprehensive and satisfactory
form the current chemical research of the
world; and
Wuereas, He has thus contributed in a vital
way to the phenomenal increase in member-
ship and scientific activity of the Society dur-
ing the last two decades, in which the success
of its journals has been one of the most im-
portant factors; now, therefore, be it
Resolved, That the Council of the Society
expresses its keen regret that other tasks have
compelled the resignation of Dr. Noyes from
the editorship of the Journal, and records its
high appreciation of his services to the Society,
especially of his ardor in developing the So-
ciety’s journals, which will remain a splendid
monument to the success of his work.

THE ANNUAL MEETINGS OF THE BIOLOGICAL
SOCIETIES
Tue annual scientific meetings of the Bio-
logical Societies (The Federation of Ameri-
can Societies for Experimental Biology, The
American Association of Anatomists and The
American Society of Zoologists) will be held in
the University of Minnesota, Minneapolis,
Minnesota, December 27, 28 and 29.
The Hotel Radisson will be headquarters for
all the societies. Arrangements will also be
made with fraternity and boarding houses for
those desiring them.
The federation has arranged to hold a day
session at the Mayo Clinic in Rochester, Min-
nesota, on December 29. For this purpose ar-
rangements have been made to have sleeping
cars leave Minneapolis on the night of the 28th
in order that no time shall be lost. The
Mayo surgical hospitals will be visited, as will
also the experimental laboratories and at the
afternoon session a scientific program will be
presented. Members of the federation should
have their tickets from the east routed from
Chicago to Minneapolis and from the west
through Omaha or Kansas City to Minneapo-
lis. Tickets for the return trip should be
routed from Minneapolis over the Chicago
and Great Western Railway to Rochester and
from Rochester to Chicago for the east, and to
Omaha or Kansas City for the west. Mem-
bers of the Anatomical and Zoological Socie-
ties are cordially invited to attend this Ro-
chester meeting if they care to do so, although
programs for these societies have been ar-
ranged for the same date in Minneapolis.
There will be a joint dinner in the Gold
Room, Hotel Radisson, on Thursday at 6:30
P.M. at $1.50 per plate, also, a joint smoker
will be held at the Teco Inn, Hotel Radisson,
at 8:15 p.m. on Friday. Fifty-cent luncheons —
will be served at 1 P.M. in the Minnesota
Union, University of Minnesota, each day
throughout the meetings.
After full consideration by the executive
committees and councils of the societies con-
cerned, it has been decided to hold the meet-
ings in Minneapolis on December 27, 28 and
29, as voted one year ago. This action is taken
on the ground that it would be disastrous to
SCIENCE
583
the progress of research and the best interests
of the biological sciences if no annual meetings
for the reporting of investigations, for the
exchange of ideas and for mutual encourage-
ment should be held.
The local committee at Minneapolis cor-
dially endorses this decision on the part of the
authorities of the several societies and de-
sires to emphasize in addition the impetus
that can be given to science in the northwest
by a successful meeting at the University of
Minnesota. To this end they are planning for
a program of unusual interest. Not only will
scientific papers of value be presented before
the various societies—papers which in many
instances will deal with matters pertaining to
the war—but also visitors will have an oppor-
tunity to see the recent new laboratories of
the University of Minnesota and especially to
visit under the best of conditions the Mayo
Clinic at Rochester and become acquainted
with the research work going on there under
the Mayo Foundation.
On behalf, therefore, of the University of
Minnesota and with the cordial concurrence of
its president and board of regents we invite
you to attend these meetings. We urge you
as a duty to science to help make the gathering
a success. We believe that it is incumbent
upon every scientific man to support the cause
to which he has devoted his life, the cause of
scientific progress. We, therefore, most re-
spectfully and earnestly urge you to attend
these meetings, to contribute to the programs,
to take part in the discussions and to bring to
the support of science the same loyalty and
sacrifice that America is giving to every other
basic principle of our civilization.
We also ask that you inform young scientists
of your staff and acquaintance who are not
yet members of the societies, concerning these
meetings, and invite them to be present.

DISCUSSION AND CORRESPONDENCE
SOCIEDAD CIENTIFICA ANTONIO ALZATE
For those who have been led by a perusal
of the daily papers to suppose that Mexico
was in a progressive state of disorganization,
the recent issues of the “ Memorias” of the
“ Sociedad Cientifica Antonio Alzate,” of Mex-
ico City, will afford good proof that their
hasty judgment had been erroneous.
The thirty-sixth volume of the Memorias of
this Society, which has just appeared, and
comprises 740 pages of text with 82 plates, is
entirely devoted to a monograph on the State
of Puebla by Sefior Enrique Juan Palacios.+
His study falls into three main sections, the
first of which regards the ethnology, geology
and climatology of the state, the second, its
flora and fauna, its industries, its mineral
resources, and its commerce and means of
communication; the third section treats of the
political divisions of the state, and of its

history, embracing a description of its prin-
cipal communities, chief among which is of
course the city of Puebla, consisting of about
100,000 inhabitants.
The area of the state is given by the writer
as 33,653 square kilometers, or about 14,000
square miles, and its population as nearly
1,100,000, showing a density of nearly 80 to
the square mile. In population it ranks third
among the Mexican states. The white race
numbers 86,000, the population of mixed race
826,000 (three quarters of the whole), and the
Indians, nearly 200,000. Within its territory
is the highest peak in North America, with the
exception of Mount McKinley. This is the
mountain bearing the Indian name Citlaltépal,
or “Smoking Mountain,” though often called
Orizaba. It rises to a height of 5,675 meters,
or 18,614 feet, and is an extinct, or at least
an inactive voleano.
The fossil remains found in the state of
Puebla are of considerable importance. Among
them are bones of Hlephas Columbi Falconer,
found at San Jeronimo, in the district of
Tehuacan, and also in the region about the
city of Puebla. Within the limits of its mu-
nicipality, at Molino de Santa Barbara, fossil
elephant tusks have been unearthed; masto-
don tusks have also been discovered in the
state, as well as teeth of Elephas primigenius
(pp. 54, 55).
Ample space has been devoted to the min-
eral resources of Puebla and to their exploita-
tion. While the principal interests of the
state are agricultural and industrial, there
were, according to the statistical report of
1907, as many as 29 mines then in operation
(copper, iron, gold, silver and lead), the num-
ber of persons employed being 1,068; the pro-
duction was valued at 1,168,428 Mexican
dollars. Most of these mines must have been
small undertakings, since Southworth in his
Mining Directory for 1908 only notes three
mines as in active operation, that of San
Lucas (gold and silver) in the district of
Tehuacan; that of Tetala, an English com-
pany organized in 1904, with a capital of
£100,000, ‘lay Aurora, Olin
Tezuitlan, an enterprise dating from 1905,
and the mine

and having resources put at 10,000,000 Mex-
ican dollars.
Of what might be called precious-stune ma-
terial there is very little signalized; some opal
is found at Tecali and Tlatlauqui, and azurite
occurs in Acatlan. The so-called “ Mexican
Onyx” (an aragonite) of the district of Tecali
in the state of Puebla is well known, and was
already used by the Aztecs for ornamental
purposes.
In the State College in Puebla, where courses
of law, medicine and engineering are given,
besides the customary preparatory studies,
there are excellent collections illustrating
physics, chemistry, bacteriology and histology,
and also radiographic and radioscopic instal-
lations, as well as apparatus for wireless tele-
graphy. There is also a well-furnished na-
tural history collection and an important.
museum.
The few items presented here may give a
little idea of the quality of this monograph,
though insufficient to indicate the wide field
it so ably covers. It certainly merits to be
consulted by all who are seeking information
regarding one of the principal states of the
Mexican Federation. Grorce F. Kunz

THE TALKING MACHINE AND THE
PHONOGRAPH
To tHe Eprror or Science: Professor Peck-
ham’s interesting account of the talking ma-
chine, as distinguished from the phonograph,
in Science of November 9, closes with this
statement:
It is not probable that any one had thought of
a phonograph in the sense in which we use the
term as early as 1772. Knowledge of electricity
was not sufficiently advanced at that time.
This, I presume, is a mere slip of the pen,
the writer thinking perhaps of the telephone
while writing of the talking machine and the
phonograph. Otherwise some of us who are
engaged in other fields of science, and hence
can lay claim to no special knowledge of phys-
ics, would like to have pointed out to us the
connection between electricity and the ubi-
quitous phonograph.

SCIENTIFIC BOOKS
Mental Adjustments. By Freprrick Lyman
We tts, Ph.D. New York & London: D.
Appleton & Co., 1917.
F. L. Wells wrote his book with a rather
unusual background. Trained in the experi-
mental school of Cattell and Woodworth, Wells
took up his work at the McLean Hospital in
1907, where he returned after one year’s work
with Dr. August Hoch on Ward’s Island and
with considerable contact with Dr. Charles
Macfie Campbell, to whom the book is dedi-
cated. Coming from a school which might be
frankly dynamic and objective, if it had the
necessary philosophical courage combined with
a desire for consistency, Wells found most
valuable opportunities at the McLean Hospital
owing to the excellent tradition established
there by Dr. Hoch in the study of an uncom-
monly interesting type of patients; and even
before he went to Ward’s Island he had been
concerned with association experiments and
with problems which were bound to bring him
into touch with the sphere of ideas of Freud
and Jung. His studies of the last few years
have shown a growing mastery of the psycho-
pathological problems and the present book
gives ample evidence of earnest and able col-
laboration along lines very characteristic of
modern American psychopathology.
Eight chapters constitute this book of 331
pages. In “Mental Adaptation” he gives
illustrations of types and problems of adapta-
tion and in a way a forecast of the book. The
discussion of “Use and waste in thought and
‘conduct ” leads the reader, in one of the best
organized chapters of the book, to a very direct
understanding of fundamental adaptive trends
and their adjustments and supplements, many
times crossing the boundary between the
“motor” and “mental” varieties of behavior,
“oranting, indeed, that such a boundary
exists.” He gives a very good picture of the
role of fancy and autistic thinking (7. e.,
primitive faney unconcerned about reality)
and especially of the réle of word-plays and
of rationalization. He sums up the discussion
by saying that “realistic thinking contributes
mainly to making it possible to exist, and
588
autistic thinking to making it worth while to
live.”
Pages 71 to 113 are devoted to Symbolic As-
sociation, in a chapter showing a remarkably
wide range of resources of reading, and lead-
ing from the symbolisms of language and of
normal waking life to those of dreams.
The discussion of emotion is given the title
“The continuity of emotion,” and deals with
“affective displacement’? (a somewhat ques-
tionable term for affective diffusion and dis-
proportions) and affective compensation. The
more specific types of “ affective displacement ”
are exemplified by a number of “ unaccount-
able” dislikes and in the use of contrast and
exaggeration in humor. “Loaded” experi-
ences and transference are reduced to the prin-
ciple that emotions are to be viewed as reac-
tions, which are switched in and out accord-
ing to the principle of associated reflex and
conditioned and associated responses. The
switching off of the affect is spoken of as a de-
emotionalizing and siphoning process. The
role of various complexes and affective sym-
bolism is illustrated by many examples. The
phrase “Objekt vergeht, Affect besteht” ex-
presses the meaning of the title of the chapter.
The discussion of “ Types. of Dissociation ”
is more clearly systematic than most of the
rest of the book and is a valuable survey for
the student, although perhaps somewhat
heavily loaded with varieties and subvarieties
for those readers who have but little concrete
experience, and who might have a desire for
principles rather than for details. Chapter
VI. (pp. 204-226) takes up the dynamic im-
portance of factors which determine repres-
sions and its various degrees. Chapter VII.
takes us into the field of available experi-
mental approaches, with a discussion of vari-
ous types of intelligence tests, the association
method, and those involving what is called
measurements by relative position (the “ better
or worse’’), free association, the schedule of
personality study; and a final chapter dealing
with “ Balancing Factors ” gives a valuation of
various trends for life and the quest of happi-
ness and application to education.
It is, I suppose, both a merit and a draw-

[N. S. Vou. XLVI. No. 1198
back of the book that it resists a brief sum-
marizing survey. Clearness of principles and
the ease of reading might readily gain by
moderation in the amount of illustration and
in the use of metaphors, or, since most of
these are really well chosen, by paragraphs of
orientation. The few paragraphs of this char-
acter certainly do much to make one more
receptive.
Wells puts forth as his aim not to tell us
things, but to enable us to see for ourselves
what we would otherwise miss. He does, in
fact, tell us so many things that one feels very
much the importance of what he himself ealls
“strategic regrouping,” of the author’s treas-
ure of reading and of observation. Every
“reader of the replete volume must be willing
to do his share; those who do so will certainly
find a rich material and ample work. How
readily the book would lead one not already
experienced in the field will have to be tried
out. The reviewer can not help feeling that
medical responsibilities with the cases and the
material might have added a kind of practical
simplicity and directness where the reader
might be apt to lose himself in the detail.
Wells does, however, make it clear that the
normal and the abnormal are made of much
the same material, and his book, with its soft-
ened rendering of Freudian conceptions, will
be a stimulus and a help along sane and useful

This book gives an elementary treatment of
the methods of adjusting observations. The
normal or Gaussian law of error is derived
from Hagan’s hypotheses regarding the nature
of errors, and the presentation in this connec-
tion is very attractive. The book gives a brief
and simple treatment of certain important
parts of the theory of statistics. This includes
Pearson’s generalized frequency curves first
published in the Philosophical Transactions of
DrceMBER 14, 1917]
the Royal Society, 186 A, p. 843. These curves
include six types besides the normal curve, but
the book makes no reference to the five addi-
tional types of curves recently published by
Pearson. The book presents a treatment of
the correlation of two systems of variates. The
treatment is, in general, clear, and should
serve a useful purpose in making better known
to persons who are applying these methods to
data the nature of some of the limitations that
underlie the interpretations of correlation co-
efficients. However, the reviewer has one
criticism to offer. On p. 155, using r for the
correlation coefficient, we are told that “it
seems doubtful whether any serious meaning
can be attached to values of r which are less
than .5.” It seems to the reviewer that this
statement should be modified. To be sure, the
statement would hold if the correlation coeffi-
cient r were calculated from such a small num-
ber of observations that the probable error of r
is not particularly small compared to r. But
when the conditions under which the formula
for probable error of r is derived are well satis-
fied, r may be much smaller than 0.5 and have
decided significance if derived from large
enough number of observations to make its
probable error small in comparison to the value
of r.
A useful chapter is devoted to harmonic
analysis from the standpoint of least squares,
including an interesting section on a practical
method of investigating periodicities. The
last chapter deals with the periodogram, in-
cluding a treatment of hidden periodicities.

THE PRODUCTION OF GASEOUS IONS AND
THEIR RECOMBINATION
GASEOUS ionization has played a large part in
recent advances in both physics and chemistry.
In the ordinary college- and _ high-school
courses given in these subjects little, if any,
attempt is made, however, to demonstrate
methods of producing gaseous ions or of meas-
uring their recombination or diffusion con-

stants. Practically no laboratory work along
these lines by elementary students is attempted.
This may be explained in part by the fact that
most investigators in this field of research have
made use of the electrometer, an instrument
well adapted for demonstration purposes but
inappropriate for use by the inexperienced stu-
dent. An electroscope of very simple design
has, however, proved entirely satisfactory in
place of the more cumbersome and possibly less
sensitive electrometer.
Some elementary experiments are suggested
in the first part of this paper using apparatus
involving little or no expense and which may
be assembled by any high-school student. This
is followed by a description of some results ob-
tained in verification of the law governing the
recombination of the ions of a gas.
PART I
The type of electroscope used is shown in
Bigs il.
A brass rod passes through a sulphur plug
into the hollow cylindrical chamber (CC) 12
em. high and of 4 cm. radius. On this rod is
mounted a flat brass strip which supports the
gold leaf. The top of this mounting projects
through a large opening in the square metal
box surrounding the gold leaf to permit the
electroscope to be charged by removing the
metal cap (D). (B) is a brass tube approxi-
mately 2 meters long the radius of which will
depend upon the laboratory facilities for pro-
viding a suitable current of gas. If air ioniza-
tion is to be studied and compressed air is not
available, a suction pump attached to a water
faucet will provide a convenient velocity for
carrying ionized air through (B) if its radius
is of approximately 3 cm. diameter.
ee
590
The velocity of the ions and consequently
the time taken for their passage over a given
distance may be obtained by measuring the
volume of air passing in a given time. A
common gas meter (JM) provided with a dial
one turn of which registered one half of a
cubic foot was used in these experiments. The
air passing through the tube may be dried by
calcium chloride and ions prevented from en-
tering with the air stream by a plug of cotton
wool placed at (#). Lead screens (9) should
be erected to shield the electroscope from direct
radiation. Provided radium salt be used as
ionizing agent at a short distance from the
electroscope, these screens will need to be sev-
eral centimeters thick.
The gas passing through the tube may be
ionized by X-rays or Y-rays shot through a slit
(f) cut in the tube and covered by a thin mica
sheet, or the ionizing source may be placed in-
side the tube. A 2 or 3 mm. spark between
the secondaries of an induction coil sealed into
the tube provides a convenient source of ioniza-
tion for demonstration purposes. X-rays also
produce powerful ionization effects. A 2-inch
X-ray bulb run at dull luminescence by a coil
capable of producing a 4 cm. spark will pro-
vide sufficient ionization for the experiments
described below.
A Nernst lamp is more suitable for project-
ing the gold leaf on a screen than the ordinary
lantern. For laboratory work a low powered
microscope with a divided scale in the eye
piece is used for measuring the rate of fall of
the gold leaf.
An electroscope of the type shown in Fig. 1
may be made of comparatively small capacity.
If the leaf be charged to a relatively high po-
tential, it becomes an instrument of- high
sensibility. Owing to the extremely small
mass of the gold leaf it will rapidly alter its
rate of deflection as the number of ions swept
into the chamber changes.
Place the X-ray bulb directly over the*elec-
troscope and charge the gold leaf, by means of
an ebonite rod, till it shows large divergence.
Run the bulb for an instant and the gold leaf
at once drops a distance proportional to the
ionization produced in the electroscope by di-

rect radiation. If the charging cap is not re-
placed before starting the bulb, the sudden
drop takes place as before, but the leaf instead
of stopping its motion as suddenly as it be-
gan gradually slows up with time. This effect
is produced by the ions in the air surrounding
the electroscope rapidly diffusing into it, the
number diminishing as recombination takes
place. Some idea of the rapidity with which
the leaf comes to rest may be obtained from
Table I. The numbers represent readings on
the scale between the intervals stated in the
first column. The readings with 3 second in-
tervals were observed and recorded without as-
sistance. Shorter intervals required assistance
in making the record.

Place the X-ray bulb over the slit as indi-
cated in Fig. 1 and start the suction pump.
When the radiation passes through the slit
large quantities of positive and negative ions
are produced in the air stream directly be-
neath. If the bulb is but a short distance
from the electroscope and the air velocity is
high, a large proportion of the ions originally
produced will be swept into the chamber caus-
ing a rapid rate of fall of the gold leaf. The
remainder have either recombined or diffused
to the side of the tube. Since the negative
ions diffuse more rapidly than the positive, the
DrceMBER 14, 1917]
tube should be earth connected. When the
bulb or spark gap is 2 or 3 meters from the
electroscope and the air velocity is diminished,
a considerable time will elapse before any of
the ions can reach the electroscope and these
will be but a small percentage of the number
originally present.
As the first ions arriving are swept into the
chamber of the electroscope the leaf begins to
move and its rate of fall increases and finally
reaches a constant value which is maintained
until a short time after the X-rays (or spark)
is stopped, following which the rate of leak
slowly reduces to zero. The apparent slow-
ness of the leaf in starting and stopping is
largely due to the effect of friction between
the air and the inner surface of the tube.
This appreciably diminishes the velocity of
the air in that region, so that on starting, ions
passing through the central portion of the
tube arrive first. After the rays are stopped,
ions near the surface trail along behind, grad-
ually decreasing in number as recombination
and diffusion proceed. The effect will of
course vary with the length, diameter and
material of the tube and the velocity of the
air. It will later be shown that this irregular
distribution of ions in the tube may affect
the value obtained for the recombination con-
stant. For high velocity and a short length
of tube the leaf starts at once with a uniform
rate of deflection and stops abruptly. Using
a spark gap 2 meters from the electroscope
and a slow air current, a relatively large rate
of leak was observed after 85 seconds had
elapsed between the stoppage of the spark and
the arrival of the first ions in the chamber.
The rapidity with which gaseous ions dif-
fuse may be- well illustrated by inserting a
compact bundle of tiny, thin-walled metal
tubes inside the tube near the slit. These
should be soldered together and make good
contact with the inner surface of the tube.
Diffusion takes place so rapidly, as the ions
pass through the tubes, that with the same air
velocity and ionizing source, the number of
ions reaching the electroscope is enormously
diminished.
The effect of water vapor or dust particles

in increasing the ionization, where otherwise
the conditions of experiment remain un-
changed, is easily demonstrated.
PART II
Experimental Proof of the Law of Recom-
bination
Rutherford has shown that the rate of re-
combination, at a given instant, of the ions
produced in gases exposed to X-rays! and the
radiation from uranium? is proportional to
the square of the number present at that in-
stant, from which it follows that
= —_— += at,
where V and n are the number of ions present
in the gas at the beginning and end of time
t, respectively. This law has also been verified
for gases exposed to X-rays by McClung? also
by McClelland‘ using ares and flames as the
ionizing agents.
The method most generally employed when
large quantities of the gas are available has
been to pass the ionized gas through an
earthed metal tube with constant velocity and
measure the saturation currents at different
points along the tube by means of an electrom-
eter. A gas meter was used to measure the
velocity through the tube as already intimated.
The deflection of the electrometer indicates
the number of ions in a certain portion of
the tube at a given instant. The fall of the
gold leaf of an electroscope is, however, an in-
tegrating process like that of the gas meter
and continues over a considerable time for
each reading.
If the ionizing agent or the velocity of the
ions themselves should undergo slight changes,
the rate of fall of the gold leaf would give a
good indication of the average number of ions
passing at a given time. The sensibility of
the electroscope will also remain fairly con-
stant over long intervals and is readily tested.
. In the course of some work involving the
use of X-rays and Y-rays from radium salt, it’

was necessary to measure their relative ioniz-
ing effects at a given point in air. This was
accomplished by sucking the ionized air from
the vicinity of the given point through a metal
tube into the chamber of an _ electroscope
placed at some distance, as shown in Fig. 1.
By noting the rate of deflection of the gold
leaf for different air velocities curves corre-
sponding to decay curves were plotted, using
ionization in divisions per minute as ordi-
nates and the times of passage of the ions
through the tube as abscisse. By contin-
uing these curves back to zero time an ap-
proximation was obtained of the relative
ionization originally present. A more exact
estimate was made by obtaining the recom-
bination constants for the two ionizing agents
and, assuming the square law, calculating the
original ionization when the ionization after
a given time was known. This work sug-
gested a further study of the recombination
constants by this method, using various ion-
izers, and an examination of the recombina-
tion constants for ions produced by “hard”
X-rays or the more penetrating Y-rays as com-
pared with these values for the softer and less
penetrating radiations.
Before using the electroscope as an indi-
eator of the number of ions present at any
instant, it was necessary to determine the de-
flection to which the gold leaf must be charged
in order to obtain saturation conditions for
the maximum velocity utilized. This was
found by passing the ionized gas through the
chamber of the electroscope to be used, then
through the chamber of a second electroscope
of high sensibility in close proximity to the
one to be tested. The gold leaf of the latter
was then charged to a potential sufficient to
give no leak in the auxiliary electroscope.
For lower potentials ions escaped into the
second electroscope and the rate of leak of
the first did not give a true indication of
the number of ions passing into it. When the
potential to which the leaf is charged is con-
siderably lower than that necessary for satu-
ration the decay curves obtained may show a
maximum point, since there may be a critical
velocity at which a maximum number of ions
SCIENCE
[N. S. Vou. XLVI. No. 1198
will give up their charges to the electroscope.
At such a velocity the gain in the. number
entering the chamber will be counterbalanced
by the number escaping without giving up
their charges.
The order of experiment was then as fol-
lows: Determine the saturation potential
necessary for a given position of an ionizing
agent at the maximum velocity to be used.
Obtain the natural leak of the electroscope
when the ionizing agent was present, but with
no current passing through the tube. Obtain
rates of deflection of the leaf in divisions per
minute for each of as large a number of dif-
ferent velocities as time and the capacity of
the suction pump would permit. The leaf
was charged to a given deflection and allowed
to leak over the same number of divisions
for each reading. The mean of several ob-
servations was taken at each velocity. Succes-
sive times for the flow of .5 cubic foot of gas
through the meter at a given velocity were
also recorded. These values were then plot-
ted using ionization in divisions per minute
as ordinates and cubic feet per minute as
abscisse. From the smooth curve thus ob-
tained a number of points were chosen and
the time of decay of the ionization to these
given amounts calculated from the rates of
flow. Two of the ionization values were then
selected as representing N and 7 in the for-
mula

where ¢ was the difference between the cal-
culated times of decay for the values chosen.
Thus assuming the recombination law, a the
recombination constant was calculated in ar-
bitrary units. Using this value for a, a num-
ber of values for n were computed and com-
pared with the experimental values. The ion-
izing agent was then placed at different dis-
tances from the electroscope and similar de-
cay curves plotted as a series of checks and
with the purpose of obtaining a better idea
of the part played by diffusion. This was
repeated for brass tubes of different diameters,

was contained in tiny aluminum tubes .7 mm.
thick and approximately 2 em. long. These
were sealed into thin glass tubes to prevent
leakage of radium emanation, and when used
inside the brass tube were suspended at its
axis by silk threads. The uranium cylinder
referted to under H in Table II. was a hollow

glued on the inside. This cylinder was sus-
pended in the middle of the tube. The a
McClung? has shown that the recombination
constant does not change with the pressure
of the gas. Under the experimental arrange-

would change with the gas pressure and intro-
duce a small correction for large capacities.
Investigation showed that this change, if
assumed to be linear, would be negligible for

Neither of these causes, under the experi-

penetrating radiations.

The relation of the dissociation of hydrogen to
enzymatic activity: Howard T. GRABER and J. W.
M. BunKer. It was demonstrated that the enzyme
‘‘pepsin,’’ in agreement with the other enzymes,
invertin and catalase, has an optimum at a definite
H. ion concentration and that the presence of
other ions exerts an influence which is not measur-
able, yet not negligible. It was shown that in the
case of the weakly dissociated organie acids the
buffer effect of the protein added has a marked
effect upon the dissociation of the acids, but that
when ‘the concentration of the H ions was made
equal to that of 3 per cent. HCl by considering
temperature and protein the organic acids are
equal to 3 per cent. HCl as activators for peptic
digestion.
°
On the origin of the humin formed by the acid
hydrolysis of proteins III. Hydrolysis in the pres-
ence of aldehydes II. Hydrolyis in the presence
of formaldehyde: Ross AIKEN GORTNER and
GrorGe E. Houm. Hydrolysis in the presence of
formaldehyde completely alters the nitrogen distri-
bution obtained by Van Slyke’s method. Black
insoluble humin is formed from tryptophane and
no other known amino acid is concerned in the re-
action. The primary reaction of black humin for-
mation involves only the indole nucleus and not the
a amino group of the aliphatic side chain of trypto-
phane. Formaldehyde forms a soluble humin with
tyrosine which is precipitated by Ca(OH)... Hy-
drolysis in the presence of formaldehyde causes
enormous increases in the ammonia fraction, but
the increase is not due to ammonia, but to volatile
‘DecemsBer 14, 1917]
alkaline compounds. The detailed paper will ap-
pear in the Jour. Amer. Chem. Soc.
The effect of prolonged acid hydrolysis on the
nitrogen distribution of fibrin, with especial refer-
erence to the ammonia fraction: Ross AIKEN
GorTNER and Grorce E. Houm. Fibrin was
boiled with 20 per cent. HCl for varying periods
of time ranging from 1 hour to 6 weeks, the am-
monia fraction increases continuously, showing a
150 per cent. increase at the end of six weeks over
that obtained at the end of twelve hours. This in-
erease in ammonia comes almost entirely from the
deamination of mono amino acids. The ammonia
fraction of a twenty-four- or forty-eight-hour hy-
drolysate can not be taken as an absolute measure
of amide nitrogen, for some ‘‘deamination’’ ni-
trogen is undoubtedly present, the amount depend-
ing both upon the particular protein and the length
of hydrolysis. The paper will appear in the Jour.
Amer. Chem. Soc.
Comparative analyses of fibrin from different
animals: Ross AIKEN GORTNER and ALEXANDER
J. WuERTzZ. Fibrin has been prepared from the
blood of cattle, sheep and swine and the nitrogen
distribution determined by Van Slyke’s method.
No differences significantly greater than the ex-
pected experimental errors were found. It would
thus appear that fibrin from any of these three
sources can be used interchangeably in experi-
mental work without invalidating the results.
Whether or not this is true for fibrins from other
sources remains still an open question.
The nitrogen distribution in protalbinic and
lysalbinie acids: Ross AIKEN GoRTNER and Cor-
NELIA KENNEDY. Lysalbinie and protalbinie acids
were prepared from egg albumen by Paal’s method
and their nitrogen distribution, together with
that of the original egg albumen, determined by
Van Slyke’s method. No marked difference was
observed in any of the fractions, although both
of the derived products show a somewhat greater
apparent lysine content. This is probably due to
ornithine derived from arginine. The analyses
furnish no evidence as to whether or not these
‘‘acids’? are true chemical compounds or as to
whether or not their structure is more simple than
is that of egg albumen. The paper will appear in
the Jour. Amer. Chem. Soc.
On the relative imbibition of glutens from
strong and weak flours: Ross AIKEN GORTNER
and EvereTT H. Donerty. The gluten was washed
from both ‘‘strong’’ and ‘‘weak’’ flours and the
hydration capacity of the colloids measured by im-
SCIENCE
597
mersing weighed disks in different concentrations
of certain acids, allowing them to remain a defi-
nite length of time and again weighing. Lactie
and acetie acids produced greatest imbibition, the
form of these hydration curves being very differ-
ent from those of hydrochloric and oxalie acids
which produced much less hydration. The gluten
from a ‘‘weak’’ flour has a much’ lower rate of
hydration and a much lower maximum hydration
capacity than has the gluten from a ‘‘strong’?
flour. Gluten from a ‘‘weak?? flour changes from
a gel to a sol at a much lower degree of hydration
than does that from a ‘‘strong’’ flour. There is
an inherent difference in the colloidal properties
of the glutens from ‘‘strong’’ and ‘‘weak’? flours
and these glutens would not be identical even if
the flours had originally had the same salt and
acid content. The paper will be published in

The composition of oil of cassia. II: Francis
D. Dovar. In a previous paper, the writer and A.
E. Sherndal have reported the examination of the
alkali-soluble portion of the oil of cassia, binding,
as new constituents, coumarin, salicylic aldehyde,
salicylic and benzoic acids, and a liquid acid, not
identified. The writer has recently examined the
aldehydes present in the oil, and has identified, as
minor constituents, benzaldehyde and methyl-sali-
cylaldehyde, The latter was isolated as the oxime,
melting at 90°, and identified by conversion into
methyl salicylie acid. No positive indication of
the presence of hydrocinnamic aldehyde was found.
Molecular rearrangements in the camphor
series. The decomposition products of the methyl
ester of the isoaminocamphonanic acid. A new re-
action involving the formation of the methyl
ether of a hydroxy acid: Wituiam A. Noyes
and GLENN S. Skinner. Several years ago L. R.
Littleton and one of us were engaged upon the
study of the decomposition of isoaminoecampho-
nanie acid with nitrous acid. Cis-camphonololac-
tone was the only product identified. We have
undertaken the study of the decomposition of the
methyl ester with the intention of separating the
products by fractional distillation under diminished
pressure. The products that would be normally
expected are a methyl ester of a hydroxy (trans-
camphonolic) acid with hydroxyl in place of the
598
amino group and a methyl ester of a A, unsatu-
rated acid containing a gem methyl. Neither of
these compounds has been found, but, instead, at
least six compounds involving rearrangements.
Our results show that the methyl ether and methyl
ester of cis-camphonolie acid and the methyl esters
of lauronolie acid, 1, 2, 2, trimethyl 1-carboxy
eyclopentene-4, cis 1, 2, 3 trimethyl 2-hydroxy 1-
cyclopentanoic acid, and a secondary (#-hydroxy
acid are formed. The method of preparing the
materials and a more detailed discussion of the
work are reserved for publication in the Jour.

The synthesis of certain terpene homologs from
1, 4-diisopropyl cyclohexane: M. T. BocErt and C.
P. Harris. Three new homologs of the terpenes
have been prepared from 1, 4-diisopropyl cyclohex-
ane. These new terpene bodies contain two olefin
side chains in para position and represent hydro-
carbons of a somewhat different type from any
hitherto described. One is a derivative of an ordi-
nary benzene nucleus, one of a dihydro- and the
other of a tetrahydro benzene nucleus. Various
properties of these substances are described.
Further studies of o-uraminobenzoic acid,
benzoylene urea and related compounds: M, T.
Bocert and G. ScatcHarD. Experiments are re-
corded with 5-nitro anthranilic acid, o-uranimo-
benzoie acid, dinitro uranimobenzoie acid, benzoy-
lene urea and various derivatives of the above.
The synthesis of certain substituted pyrogallol
ethers derived from syringic acid: M. T. BoGErt
and J. EuruicH. These new compounds include a
dimethoxy phenacetine whose physiological proper-
ties are now being studied at the College of Physi-
cians and Surgeons, and which is at least no more
toxic than ordinary phenacetine, and possibly less
so; and also a homoantiarol, which is of interest
from the fact that it is a homolog of the so-called
antiarol isolated from antiaris toxicaria.
A substance which in the liquid phase exhibits
a minimum of solubility in an unstable region: M.
T. Bogert and J. Euruicu. A study of the solu-
bilities in water of monohydrate of 2.6-dimethoxy-
acetphenetidide discloses the interesting fact that
the liquid hydrate is unique in that it exhibits a
minimum of solubility in an unstable region.
The identity of cyanuric acid with the so-called
““tetracarbonimide’’: E. H. WALTERS and Lovis
E. Wise. The so-called ‘‘tetracarbonimide’’ pre-
pared by Scholtz by the oxidation of uric acid in
alkaline solution with hydrogen peroxide is in fact

eyanurice acid. A nitrogenous compound isolated
from a number of soils and believed at first to be
tetracarbonimide has been shown to be cyanuric
acid. Cyanurie acid has been isolated from the
following soils: (1) 12 samples of sandy soils
taken from different locations in Florida; (2)
Norfolk sandy loam from Virginia; (3) lawn soil
from the grounds of the U. S. Department of
Agriculture, Washington, D. C.; (4) Elkton silt
loam from Maryland; (5) Scottsburg silt loam
from Indiana; (6) Caribou loam from Maine,
and (7) a Susquehanna fine sandy loam from
Texas. It is apparent that cyanuric acid or its
precursor is widely distributed in soil.

Freas Electric Vacuum Oven
A Combined Vacuum and Regular Air Drying Oven
This new type Vacuum Oven was designed to meet the demand for a really satisfactory Oven
that has been created by the rapidly growing recognition of the advantages of drying in vacuo»
which allows most drying operations to be conducted more satisfactorily than in an Air Oven and in
‘one-tenth the amount of time in a great many instances.
The Freas Electric Vacuum Oven permits drying operations in vacuo to be conducted at
any constant temperature desired up to 180° C. Therugged durable construction of the Oven, its
accuracy, reliability, convenience and ease of operation render it an excellent Oven to meet the most
exacting requirements for laboratory operations both industrial and research.
An exclusive and most advantageous feature of Oven Type “RV” is that the vacuum chamber
is readily removable, allowing use of the Oven proper for regular air drying purposes during periods
when vacuum drying is not desired.

The German Biological Justification of the World War
is clearly set forth and refuted in
By VERNON KELLOGG
When the war broke out, Professor Kellogg was a neutral, a pacifist, and an admirer of
Germany.
In the hope of relieving human suffering, he left his chair at Leland Stanford Uni-
versity, went to Europe, and became special envoy of the Committee for the Relief of Belgium
at German General Headquarters and at the headquarters of General Von Bissing in Brussels.
For many months he lived on intimate terms with the leaders of the German armies in
the West.
He worked-with them, dined with them, argued with them, heard them expound the
creed of the Allmacht in defense of their aims and conduct.
Headquarters Nights not only gives an impressive and revolting picture of the
workings of German militarism among the people it has crushed, but it meets the exponents of
Kuliur on their own biological ground.
Kellogg proves that ‘‘Germany must be converted to be a good Germany or not much of any
Germany at all
In the ‘‘confessions of a converted pacifist,”
Resistance by brutal force ; war to a decision.
Professor
It is the only argument
in rebuttal comprehensible to these men at Headquarters, into whose hands the German people
have put their destiny.”’

THE STORY OF COSMOLOGICAL
THEORY1
I
Ir may be that primitive man felt none
of the
Blank misgivings of a creature
Moving about in worlds not realized.
For him, perhaps it was enough to taste
the joy of living, to watch the rising and
the setting of the sun, to gaze upon the
mountain, the river and the restless sea,
and never to ask himself the question
“what is this world in which I live, and
how did it come into being?’’ But this
problem eventually presented itself, for
there has been implanted within the human
breast that which distinguishes its possessor
from the beasts which perish, the passion
for knowledge, the deep longing for
Authentic tidings of invisible things,
Of ebb and flow and ever-during power:
And central peace subsisting at the heart
Of endless agitation.
And so there arose those questions about
himself, about the visible universe in which
he dwelt, and that invisible world about
which he dreamed, from which have sprung
all that we now call science and philosophy.
How slow and laborious have been the
steps by which knowledge has been at-
tained, and how childish and even grotesque
the answers to these first questionings.
But to have any theory at all for the first
causes of things is very much better than
to have none, and these crude products of
primitive man, and the refined deductions
of the modern scientist are the same at
1 Opening lecture of the year, delivered at the
Autumn Convocation, MeMaster University, To-
ronto.

heart. Alike they seek to deduce from
known facts the underlying principles of
nature. If the modern hypothesis appears
to lie much nearer to the truth, it is be-
cause the facts upon which it is based are
more numerous and more completely veri-
fied. Nor should we forget that it has had
the advantage of a long series of tentative
explanations, which it now replaces. All
our advances have been made over the re-
mains of discarded theories.
It is here proposed to trace in outline
the history of the theories which from time
to time have been suggested to account for
the way in which the earth was formed.
It will be seen that we have here three
stages in human intellectual development.
In the first the world was conceived to be
due to the literal handicraft of a beast, a
demigod or a divinity. In the second it
was realized that a nobler origin must be
sought, but methods of scientific criticism
had not been perfected sufficiently to put
the theories to the test. In the third, every
one had to be submitted to the most rigid
dynamical analysis.
oo
In order that these primitive theories
may have an unprejudiced hearing it is
well for us to try and put ourselves in the
place of their authors. Let us view the
world as seen through the eyes of the an-
cients.
At the time of the dawn of consciousness,
man found himself on what appeared to be
a flat and circular earth. As he extended
his wanderings this way and that, although
great ranges of mountains occasionally
stood in his way, they could eventually be
crossed, but sooner or later he seemed al-
ways to come to the shores of the impas-
sable sea. So he concluded that the disc-
shaped land was completely surrounded
by the ocean, which flowed like a mighty
river around the earth. Above him was a
SCIENCE
[N. S. Vou. XLVI. No. 1199
great dome, forming a lid to it all. This
was evidently of solid material, glass or
some metal, possibly brass. Some claimed
that it must be transparent, others, that it
was perforated by windows, for at night
the light of the celestial regions shone
through, and he ealled these bright objects
stars. The Egyptians had a slightly dif-
ferent explanation, for, according to them,
the stars were lamps hanging down from
the ceiling of the world on the end of
chains. Over this dome he saw passing,
with wonderful regularity, various bright
objects, notably the sun, and he soon ob-
served, in addition to its regularity, that it
had a very rapid motion, for it came up
from beyond the River Oceanus, probably
through a great door, in the morning, and
in about twelve hours had crossed the dome
of the heavens and was at the door of the
evening, ready for its return journey
through the upper world down to the gate
of the morning once more. This rapid
journey, in the days before steam or gaso-
line, could be explained only by the use of
swift animals, and what animals are so
swift as horses.
Above the dome of the heavens there
seemed to be another ocean, for ever and
again the roof leaked and showers of rain
fell upon the earth. It was evident also
that there must be beings there who con-
trolled the activities of nature, and prob-
ably they could occasionally climb down
by way of the sides of high mountains,
whose tops, inaccessible to man, undoubt-
edly touched the sky, and indeed, prob-
ably helped to support it.
Now all the mysterious and terrifying
forces of nature were to be explained in a
perfectly naturalistic way, by the inter-
vention of these beings from the upper
world. Was the oak under which our fore-
father had taken refuge in a storm, shat-
tered by the lightning, it was because one
of the gods had hurled a flaming dart.

Was he unfortunate enough to receive into
his veins the poison of malaria, it was be-
cause an evil spirit had entered into him
and had to be induced to come out by a
bribe, or driven out by the use of mystic
combinations of words which were calcu-
lated to cast a spell over it. So when the
author of creation was thought of it was
in the form of an animal like those he
hunted, but much bigger.

miles or less, report hearing a swishing or

buzzing sound, which seems to have been
simultaneous with the appearance of the
light. This communication is prompted chiefly
by a desire to learn if such sounds have been
previously reported as being connected with
meteoric falls. Several circumstances in the
present case indicate that this sound was real,
and not psychological. May it have been the
indirect result of some form of electric
energy? One observer seems to refer this
sound to objects attached to the ground.

ON THE COLLOID CHEMISTRY OF
FEHLING’S TEST
To tHe Eprror or Scrmnce: Fischer and
Hooker make the following statement in their
article “On the Colloid Chemistry of Feh-
ling’s Test,” page 507, Scmncr:
Formaldehyde reduces Fehling’s solution not
only to the ordinary cuprous oxide, but to the
metallic copper. The copper comes down in col-
loid form, but as this happens, a second reaction
ensues in which the metallic copper acts upon the
formaldehyde and decomposes it with the libera-
tion of hydrogen. The liberation of hydrogen con-
tinues for hours, until either all the formaldehyde
has been decomposed or all the copper salt has
been reduced.
In a study on the preparation of colloidal
gold solutions by Dr. J. H. Black and myself
(which is being reported by Dr. Black at
the present meeting of the A. M. A. at New
York), question arose regarding the probable
explanation of the mechanism by which neu-
tral sols are obtained although distinctly al-
kaline (to alizarine) sols should result from
the proportions of reagents employed. I sug-
gested the hypothesis that the colloidal gold
acted as a catalytic agent to oxidize the free
formaldehyde to formic acid, which latter
reacted with the potassium carbonate respon-
sible for the alkalinity.
It occurs to me therefore that it would be
better to picture the colloidal copper func-
tioning as a catalytic agent which oxidizes
the HCHO in part, the remaining part serving
to reduce the copper salt. The idea advanced
SCIENCE
617
by them that colloidal copper is produced is
certainly reasonable; it is very difficult to

The Fundamentals of Botany. By C. S.
Gacrr. Philadelphia, P. Blakiston’s Sons
& Co.
We are fortunate in the United States in
having a number of excellent elementary bo-
tanical text-books, written from different
points of view. Professor Coulter has fur-
nished an admirable beginners’ book conceived
from the standpoint of the head of a botanical
department in a large university, who is at the
same time an educational expert. From the
hands of Mr. Bergen, whose recent demise we
all deplore, we have had a succession of well-
approved texts, written by one thoroughly in
touch with instruction in the secondary
schools. Professor Ganong has put forward
from time to time books which reflect the
outlook of the teacher in college work. The
present volume comes from one who is the
director of one of the most important botanic
gardens in the country and who has, at the
same time, made it his business to get into
touch with his community, primary and sec-
ondary schools as well as the general public,
in the closest possible manner. There can be
little doubt, particularly at the present junc-
ture, when the general public under the spur
of patriotism and necessity, has largely aban-
doned its usual attitude of indifference
toward plants, that Dr. Gager’s book will
prove extremely useful.
The relation of the author to his subject is
admirable, as is shown by the following cita-
tion (p. 192).
. .. In faet, we may say that our ignorance of
life-processes greatly exceeds our Iknowledge.
Very much more remains to be ascertained than has
already been found out; for example, what is
protoplasm? Nobody really knows. We have
analyzed the substance chemically, we have care-
fully examined and tried (but without complete
618
success) to describe its structure. We know it is
more than merely a chemical compound. It is a
historical substance. A watch, as such, is not.
The metal and parts of which a watch is made,
have, it is true, a past history; but the watch
comes from the hands of its maker de novo, with-
out any past history as a watch. But not so the
plant cell. It has an ancestry as a cell; its proto-
plasm has what we may call a physiological mem-
ory of the past. It is what it is, not merely be-
cause of its present condition, but because its an-
eestral cells have had certain experiences. We
can never understand a plant protoplast merely by
studying it; we must know something of its gene-
alogy and its past history.
It will be noted that although a physiolo-
gist in outlook, he has properly emphasized
the historical and structural point of view so
often and so deplorably neglected by the cul-
tivators of disembodied plant physiology.
The author obviously considers that living
matter is to be studied in vita rather than in
vitro (whether in glass models or merely in
chemical glassware). By his broad outlook
he has avoided the narrows which lead, on the
one hand, into the ancient Scylla of syste-
matic botany, or, on the other, into the more
modern Charybdis of plant physiology.
The book is admirably printed on thin
paper, so that its more than six hundred
pages and well over four hundred illustrations
make a conveniently thin and flexible volume,
which is rendered still more useful by soft
covers and rounded corners. The illustra-
tions, whether original or borrowed, are for
the most part good, and in some instances are
of striking excellence. An adequate amount
of space is given to the important themes of
genetics and evolution, while the historical
side is not neglected. Dr. Gager’s work
should be in the hands of every teacher of
botanical science, and by its broadness and
balance is admirably adapted for use in
schools where the one-sided teaching of the
facts of botany is by necessity and common
sense excluded. The general text is accom-
panied by a laboratory guide, which is in-
geniously contrived to avoid repetition and
equally emphasizes structure and function.

WHY CHLOROFORM IS A MORE POWERFUL
AND DANGEROUS ANESTHETIC
THAN ETHER
ANY one accustomed to administering an-
esthetics has observed that the amount of
chloroform necessary to produce deep narcosis
is less than that of ether; also that the period
between slight and deep anesthesia is shorter
and the lethal dose smaller with chloroform
than with ether. These differences in the
effects of ether and chloroform led Hewitt to
state in his book on “ Anesthetics” that
chloroform is seven or eight times more power-
ful as an anesthetic than ether. In chloro-
form poisoning it is known that many of the
organs, particularly the liver, are very seri-
ously injured, while it is more difficult, or im-
possible in many instances, to produce such
injuries with ether.
It is now recognized that in both chloroform
and ether anesthesia oxidation is decreased or
rendered defective, as is indicated by the de-
creased oxygen intake and carbon dioxide out-
put and the appearance of certain incompletely
oxidized substances such as B-oxybutyrie and
diacetie acids, and acetone. The decreased
oxidation in anesthesia with resulting acidosis
is much more likely to occur and to a much
greater extent with chloroform than with
ether.
Using practically all the means by which it
is known that oxidation can be increased in
an animal, as, for example, by food, by in-
creasing the amount of work, by fight, or by
thyroid feeding, we have found that there is
always an accompanying increase in catalase,
an enzyme in the tissues which possesses the
property of liberating oxygen from hydrogen
peroxide. We have also decreased, or rendered
defective, the oxidative processes in animals,
as, for example, by decreasing the amount of
work, by starvation, by phosphorus poisoning,
or by extirpation of the pancreas, thus pro-
ducing diabetes, and have found that there is
always a corresponding decrease in catalase.
From these results it was concluded that it is
probable that catalase is the enzyme in the
body principally responsible for oxidation.
DECEMBER 21, 1917]
The object of the present investigation was
to determine if catalase is decreased more
quickly and more extensively during chloro-
form anesthesia than during ether anesthesia
parallel with the greater decrease in oxida-
tion and the quicker and more powerful ac-
tion of chloroform. Cats were used in the
experiments. The anesthetics were admin-
istered by bubbling air through ether or chloro-
form in a bottle which was connected by a
rubber tube to a cone adjusted to the snout of
the animal. The catalase content of the blood,
taken from the external jugular vein, was de-
termined before the administration of the an-
esthetic and at intervals of 15 minutes during
the administration. The determinations were
made by adding 0.5 e.c. of blood to 250 e.e. of
hydrogen peroxide in a bottle at 22° C. and
as the oxygen gas was liberated it was con-
ducted through a rubber tube to an inverted
graduated cylinder previously filled with water.
After the volume of gas thus collected in ten
minutes had been reduced to standard atmos-
pherie pressure, after resulting volume was
taken as a measure of the amount of catalase
in the 0.5 e.c. of blood. The bottles were
shaken in a shaking machine during the de-
terminations at a rate of about 180 double
shakes per minute.
The average amount of oxygen liberated by
the blood of three cats previous to the admin-
istration of ether was 812 ¢.c.; that liberated
after the animals had been under ether for 15
minutes was 740 cc.; that after 30 minutes of
ether anesthesia, 630 cc.; that after 45 min-
utes, 475 cc.; that after 60 minutes, 480 cc.;
after 75 minutes, 400 cc.; and that after 90
minutes, 380 ce. It will be seen that the cata-
lase of the blood was gradually decreased dur-
ing the 90 minutes of ether anesthesia, as is
indicated by the gradual decrease in the
amount of oxygen liberated, and that at the
end of 90 minutes the catalase had been de-
creased by about 54 per cent., as is indicated
by the decrease in the amount of oxygen
liberated from 812 ce. to 380 ec.
Similarly determinations were made of the
catalase of the blood of cats previous to chlo-
roform anesthesia and at intervals of 15 min-
SCIENCE.
619
utes during the anesthesia. The average
amount of oxygen liberated by the blood of
three cats previous to the administration of
chloroform was 900 ¢c.c; that liberated after
the animals had been under chloroform anes-
thesia for 15 minutes was 525 e.c.; that after
380 minutes, 325 ¢.c.; that after 45 minutes,
334 c.c.; that after 60 minutes, 320 c.c.; after
75 minutes, 3380 ¢.c.; and that after 90 min-
utes, 310 c.c. It will be seen that the chlo-
roform produces a very abrupt decrease in the
catalase of the blood during the: first fifteen
minutes of the administration as is indicated
by the decrease in the amount of oxygen liber-
ated from 900 to 525 c.c., and that at the end of
90 minutes the catalase had been decreased by
about 65 per cent., as is indicated by the de-
crease in the amount of oxygen liberated from
900 to 310 e.c.
By comparing the decrease in the catalase
produced by ether and by chloroform it will be
seen that the ether produced a gradual de-
crease as is indicated by the gradual decrease
in the amount of oxygen liberated by 0.5 e.c.
of the different samples of blood from hy-
drogen peroxide, whereas chloroform produced
a very abrupt decrease during the first fifteen
minutes of narcosis as is indicated by the
great decrease in the amount of oxygen liber-
ated from 900 to 325 e. ¢.
We have shown that small amounts of chlo-
roform or ether added to blood in vitro destroy
the catalase of the blood very rapidly. We
have also shown that the liver is the organ
in which eatalase is formed, given off to the
blood carried to the tissues.
The explanation that suggests itself for the
decrease in the catalase of the blood produced
during chloroform and ether anesthesia is the
direct destruction of the catalase of the blood
by the anesthetic and the decrease output of
the catalase from the liver brought about by
injury of the liver by the anesthetic. The
more powerful and dangerous effect of chlo-
roform as an anesthetic is attributed to the
fact that chloroform is more potent than ether
in producing a decrease in catalase, both by
direct destruction of the catalase of the blood
and by injuring the liver, thus decreasing the
620
output.of catalase from this organ with re-
sulting decrease in oxidation. In fact it is
probable that the cause of anesthesia is to be
found in the decrease in the oxidative proc-
esses particularly of the nervous system pro-
duced presumably by the destruction of the
catalase by the anesthetic. The specific action
of anesthetics on the nervous system, accord-
ing to this hypothesis, is due to the greater
solubility of the lipoids or fat-like substances
of nervous tissue which facilitates the entrance
of the narcotic into the nerve cell and thus
exposes the contained catalase more directly to
the destructive action of the drug.

THE AMERICAN ASSOCIATION OF
VARIABLE STAR OBSERVERS
Tue formal organization meeting of the Ameri-
can Association of Variable Star Observers was
held at the Harvard College Observatory, Cam-
bridge, Mass., on November 10th and was attended
by 25 or more members, almost all of whom are
active participants in the observation of variable
stars. The meeting was called to order by Wm.
Tyler Olcott, who for the past six years has acted
as secretary of the informal association, and A. B.
Burbeck was appointed temporary chairman. A
carefully drawn up constitution was read and ac-
cepted and then the officers and council members
of the association were duly elected. D. B. Pick-
ering, of Hast Orange, N. J., was elected president;
H. C. Bancroft, Jr., of West Collingswood, N. J.,
vice-president; W. T. Oleott, of Norwich, Conn.,
secretary, and A. B. Burbeck, of North Abington,
Mass., treasurer. The four members of the coun-
cil are Professor Anne 8, Young, of Mt. Holyoke
College Observatory, J. J. Crane, of Sandwich,
Mass., for two years, and Miss H. M. Swartz, of
South Norwalk, Conn., and C. Y. McAteer, of
Pittsburgh, Pa., for one year.
While waiting for the result of the election to
be announced by the tellers, a general discussion of
the most suitable size of telescope for the use of
the observers was opened up, and later, a discus-
sion of plans for the most systematic observation
of the 300 or more variable stars under research
was also freely indulged in.
In taking the chair as the first president of the
association, Mr, Pickering reviewed, in a few
SCIENCE
[N. S. Vou. XLVI. No. 1199
words, the past achievements of the Variable Star
Observers, and mentioned their aims for the fu-
ture.
Tea was kindly served by the director of the ob-
servatory in the afternoon, and then lantern slide
exhibits were given, one by Miss A. J. Cannon,
showing some of the celestial wonders as revealed
in the photographic telescopes, and another by Mr.
Leon Campbell, illustrating the progress of the
study of the star SS Cygni and what attempts are
being made to fathom its seemingly irregular vari-
ations, both in light and period.
While an inspection of the work of the observ-
atory was being made, the more experienced mem-
bers observed this same SS Cygni in the comfort-
able 12-inch Polar Telescope, all under like condi-
tions, and the result of the estimates of the 17
observers was that the star was then of the mag-
nitude 11.21, with a probable error of 0.12 magni-
tude.
At a short meeting of the council, three noted
variable star observers were elected to honorary
membership, Professor EH. C. Pickering, director
of the Harvard Observatory; Rev. J. G. Hagen,
director of the Vatican Observatory, Rome, and
Professor J. A. Parkhurst, of the Yerkes Observa-
tory. Professor Pickering was also elected as the
first patron of the association.
The council also elected nine members to life
membership and the total membership therefore
numbers 84, of which 72 are active; 9, life, and 3
are honorary members, with 1 patron.
A sumptuous banquet was served in Boston that
evening at which 20 members and four guests were
present. Interesting after dinner speeches were
made by Professors Pickering and Bailey, and Miss
Cannon and Mr, Olcott, Mr. Campbell acting as
toastmaster.
The meeting was considered the climax of all
those yet held and marks the successful launching
of a full-fledged association in America for the
regular observation of variable stars by a group
of amateur and professional astronomers, which has
been doing excellent work along this line for some
years past, and which bids fair to be even more
useful to science in the near future.
Several committees were appointed by the presi-
dent to consider the matter of telescopes, charts
and schemes of work, and it was voted by the
council to hold the spring meeting at Hast Orange,
N. J., on May 6, 1918, at the invitation of Presi-
dent Pickering.
For those members who remained in Boston
until the next day, an excursion was arranged to
DECEMBER 21, 1917]
visit the Blue Hill Meteorological Observatory,
where Professor MeAdie was most attentive and
explained in detail the investigations he is carry-
ing on there.
The opportunity for interested parties to enroll
themselves as charter members remains open until
December 31, 1917, and all such persons are invited
to join the association, to whom copies of the con-
stitution will be sent upon application to the sec-
retary, Wm. Tyler Olcott, 62 Church Street, Nor-

A reading device which permits of correct read-
ings to .001 e.c.
(b) A balance for first-year students.
A three-arm balance with non-removable riders

A study of the amount of pure water clinging
to the sides of a buret, under different speeds of
discharge. The rule is deduced that, in order that
comparable readings may be obtained, the dis-
charge should not be faster than 12 to 15 seconds
per cubic centimeter.
Limits of individuality in chemistry: N. T.
Bacon. The chances for variation become less and
less as complexity of structure is reduced, but now
that we recognize atoms as being composed of
many parts is it not proper to recognize that at
least the individual molecule, if not the atom
itself, may have an individuality? Probably each
atom would have a normal arrangement of the
multiplicity of parts going to build up the atom,
but the question is raised whether it is not prob-
able that owing to imperfect elasticity these fre-
quently stand out of the normal position with ref-
erence to each other and reducing their tendency to
combine so that frequently many times as many
collisions are necessary before completion of com-
bination as would be called for by theory.

A new hydrate of lime: H. W. CHaRuTon.
This hydrate of lime possesses marked plasticity,
and differs from the ordinary CaO.H,O in contain-
ing a considerably less amount of water. Its
method of formation precludes the possibility of
its being a mixture of CaO and CaO-H,0. One ex-
ample of its formation comprises digesting
CaO.H.O with ten times its weight of water at
225 pounds pressure for a couple of hours. The
resulting plastic material contains but slightly
more than 15 per cent. water of combination
while it originally contained over 24 per cent. and
its specific gravity is but 1.95, while that of
CaO.H.O is about 2.078. This is remarkable as
it would naturally be supposed that the specific
gravity would lie some place between that of
CaO.-3.25 and that of CaO.-2.078.
An investigation of the reaction between anti-
mony and the solutions of sodiwm in liquid am-
monia: EDwarD B. Peck. Solutions of sodium in
liquid ammonia of concentrations from 0.0049 to
1.2482 gm. atoms of sodium per liter of liquid
ammonia were sealed in glass bombs with an ex-
cess of antimony and allowed to react at room
temperature for from two months to a year. A
dark-brown, slightly soluble compound first
formed, after which a dark-red solution appeared
and the precipitate dissolved. The ratio of anti-
mony to sodium in the solution does not corre-
spond to a small integral number and changed
with the concentration of sodium. The ratio
Sb/Na changed very rapidly in dilute solutions
from a value of Sb/Na=1.98 to a maximum of
Sb/Na = 2.333 at a sodium concentration of about
0.4N, after which there was a slight decrease to a
value of Sb/Na=2.254 at a concentration of
1.248. Two plots of the results were shown, one
the ratio Sb/Na against the concentration of
sodium, and another the log. of the sodium con-
centration against the ratio Sb/Na. In both these
plots the results lay on a smooth curve. The appa-
ratus for carrying out this work was described in
detail. Weighed amounts of sodium were put up
in small glass capsules. These capsules were
placed across a tube provided with an electro-
magnetic hammer in the inside, which could be
actuated by a solenoid outside. The reaction tube
containing metallic antimony was sealed on to
this tube. The tube was also connected to a
supply of pure ammonia and to a vacuum pump.
After evacuating the apparatus, ammonia was
condensed in the reaction tube by surrounding it
with a bath of liquid ammonia. The sodium was
622
then introduced into the solution by breaking the
capsule in two with the electro-magnetic hammer.
As soon as the reaction was well started, the
bomb was sealed off and allowed to react at room
temperature. The bomb consisted of two com-
partments. When the reaction was completed,
the solution was poured off from the excess anti-
mony, and the antimony washed by distilling the
solvent over from the solution. The analysis was
completed by distilling off the solvent into
weighed water bottles and weighing the anti-
mony left behind. Electrolyses of these solutions
were carried out at the temperature of boiling
ammonia. The electrolyses showed that the com-
pounds in solution are electrolytic in nature and
that more than one atom of antimony is associ-
ated with each negative carrier. Both the analyses
and electrolyses showed that there are at least
two compounds involved in the final equilibria,
one haying more than two atoms and one having
less than two atoms of antimony for each negative
charge. These compounds are in some ways simi-
lar to the polyiodides. A detailed exposition of
this investigation will be offered for publication
to the Journal of the American Chemical Society.
The effect of acid concentration on the photo-
chemical oxidation of quinine by chromic acid: G.
S. Forses and R. S. Dean. In a previous investi-
gation of this reaction by Luther and Forbes, the
acid concentration had been constant. In the
dark, with concentrations of CrO, and purified
quinine constant, the velocity varies as the square
of the acid concentration. A shallow cylindrical
dish was bisected by a glass partition, and re-
volved under a quartz mercury lamp. Provisions
were made for stirring, cooling and temperature
measurement. Solutions as described above were
compared in pairs. After correction had been
made for the dark reaction, the velocity of the
photochemical reaction was found independent of
acid concentration. It was also proved that
quinine solution exposed to light does not retain
its activation for long in the dark.
The temperature coefficient of the distribution
ratio: G. S. Forpes and A. 8. Cooniper. Solubili-
ties in two and three component systems involving
water, ether and succinic acid were determined or
redetermined at 15°, 20° and 25°, also the distri-
bution ratio of the succinic acid between two
ether-water phases. An equation was derived
and verified showing the temperature coefficient of
the distribution ratio, with excess of the acid, as a
function of the temperature and mutual solubil-
ity coefficients of each substance in each layer.
SCIENCE
[N. S. Vou. XLVI. No. 1199
The distribution ratio, when caleulated on the
basis of ether-water phases in which the ratios
ether to water are constant, is by no means inde-
pendent of the concentration of succinie acid.
Evidence was secured that the average degree of
association of water dissolved in ether at these
temperatures is somewhat less than two.
The application of palladium as an indicator for
silver titrations: LL. SCHNEIDER. A very dilute so-
lution of palladous nitrate, dissolved in an excess
of nitric acid, is added to the silver nitrate solu-
tion which is then titrated with potassium iodide.
The silver nitrate is precipitated by the potassium
iodide and the least excess of potassium iodide is
converted by the palladous nitrate to palladous
iodide which is visible to the extent of one part in
a million. For very dilute solutions, this method
gives better precision than the Volhard method.
The size of the plus and minus errors have been
determined. The constant plus error in concen-
trated solutions is due to the palladous iodide be-
ing carried down by the silver iodide at the end-
point, whereas the negative error is caused by the
absorption of silver nitrate by silver iodide. The
standard method for overcoming these errors has
been applied with such effect that not only good
precision but satisfactory accuracy has been ob-
tained. The ease and rapidity with which the
standard solution and the indicator can be pre-
pared recommend this new method. Also the pal-
ladous nitrate method can be used to better ad-
vantage than Volhard’s in cases where the silver
nitrate solutions are colored pink or yellow. Ni-
trous acid interferes and must be boiled off before
titrating.

THE MODERN SYSTEMATIST?1
WE are still engaged in exploring the
earth, that we may understand it. We can
not understand any part of the surface of
the earth until at least three persons have
studied the area carefully: the geologist,
the physiographer, the recording biologist.
We shall never cease to explore the earth,
in old places as well as new. We can never
dispense with the recorders.
The older systematic zoology and syste-
matic botany fell into disrepute with the
competition of the exacter studies in mor-
phology and physiology, and they have been
overshadowed by the interest centering in
evolution and its derivative subjects. On
the botanical side, the naming of specimens
as an exercise in education in schools and
the making of a so-called herbarium of
snips of plants, have still further discred-
ited whatever seems to be related to syste-
matic work.
Although it is not the purpose of this
paper to discuss the educational aspects of
the subject, it may nevertheless be said
that, so far as one can determine, this
school herbarium work did not make botan-
ists, on the one hand, nor lead to an appreci-
ation of nature, on the other, and it would
be difficult to trace contributions to science
from its suggestion. As an educational
method it was faulty because it did not
connect plants with either function or en-
vironment, nor call for continued applica-
tion on the part of the pupil. The inten-
sive laboratory course that succeeded it
developed exacter methods, more sustained

delphia, November 20, 1917.
624
application, closer scrutiny or observation
and related the exercises to function. It has
failed, however, in not educating in terms
of the vegetable kingdom. We now see that
the best educational procedure for botany
in schools is a good combination of inten-
sive laboratory work indoors, with carefully
planned field and systematic work. The
field naturalist contributes the factor of
leadership in addition to drill with sub-
ject-matter; under his care, the environ-
ment of both men and other organisms be-
gins to express itself. This, of course, is as
true in zoology as in botany; in fact, good
field work is both zoology and botany.
This kind of field and collecting work pro-
vides the best approach to nature. To
know a cell or a spore is of much less sig-
nificance to the major part of mankind
than to know a plant.
Some of the disdain of descriptive and
taxonomic effort is due to the feeling, which
is not without justification, that much of
the so-called systematic work is little more
than the personal naming and re-naming
of specimens, without the addition of new
knowledge or the expression of new mean-
ings; the work is therefore likely to be dis-
regarded, as irrelevant and not worth the
while.
The systematist has also lost sympathy
with many of his compeers because of the
controversies over nomenclature. The im-
pression has gone abroad that he deals
only with names. The controversies in this
field issue from two mistaken premises on
the part of nomenclatorialists—the as-
sumption that nomenclature can be codi-
fied into invariable law, and the practise of
making rules retroactive. Varying prac-
tises in language tend in these days toward
agreement and unification, the persisting
variations being mostly in minor matters;
as soon, however, aS any superimposed au-
thority undertakes to enforce rigidity, re-

LN. S. Von. XLVI. No. 1200
bellion is invited and differences are likely
to be organized into counter codifications.
It is probably not even desirable to have
rigidity in binomial nomenclature for
plants. The reactionary nature of the
rules is their greatest fault, however, and
is responsible for most of the mischief. It
upsets good practise, on which the litera- .
ture rests, even as far back as Linneus.
Acts of legislatures, regulations of govern-
ment, ordinances, entrance requirements to
colleges and other enactments, become opera-
tive at a specified future date. The names
of plants are vested rights to the users of
them in literature, and there is no moral
warrant for changing those of times past
merely that they may conform to a rule of
the present. If the practise were in the
realm of enacted law involving property,
any court would declare it illegal. I intro-
duce this discussion to say that the changes
in nomenclature are not a necessary part
of systematic work except in so far as they
result from changed biological conceptions
of genera and species.
THE WORK OF THE SYSTEMATIST
With this preface, I may enter my sub-
ject, which is the place of the systematist
in present-day natural history. I shall
naturally speak in terms of plants, but I
trust that some of you will make the exten-
sion to terms of animals.
To know the forms of life is the primary
concern of the biologist. This knowledge
is the basis of all study in morphology,
physiology, heredity and phylogeny. Un-
doubtedly much of the looseness of state-
ment and incorrect inference in writings on
variation and heredity are due to the very
inexact definition of the forms about which
we talk. Much of the non sequitur lies
here. Literature is undoubtedly full of
examples. Every discouragement of the
DECEMBER 28, 1917]
systematist reacts on the conclusions of
those who cite the names of plants.
So fundamental is this contribution of
the systematist that we should now be very
cautious in talking of heredity in plants at
all until we have redefined their forms.
The records of variation, as such, do not
constitute definitions, but only departures
from assumed norms.
The definitions of the systematist, who
eritically surveys a wide range of material
for comparison rather than for divergence,
apply not only to the assemblages we know
as species, but also to the minor forms that
seem to have descriptive unity. If I were
now working with any group of plants in
an experimental way touching develop-
ment and evolution, I should want first to
turn the whole group over to a conservative
systematist for careful review.
I had hoped that, in the beginning of
the plant-breeding studies, the breeder
would also be a pronounced systematist
that he would aid us in the definition of
the forms of plants, and bring his experi-
mental studies to bear in tracing the prob-
able course of evolution up to this epoch,
that is, that he would contribute more freely
to the knowledge of origins. I still think
that we shall find the experimenter relating
his work more closely to systematic botany
as soon as the systematist takes cognizance
of the plant-breeder, and the plant-breeder
is satisfied that he must analyze his meas-
urements in terms of biological definition
and classification. I doubt the adequacy of
some of the biometrical computation, and I
regret the frequent neglect of herbarium
studies whereby vegetation-factors rather
than measurement-factors may be strongly
emphasized.
It is not unlikely that the ecologist falls
into false comparisons by earelessness in
identification, or by inattention to critical
differentiations. It really matters very
SCIENCE
625
much whether a given distribution repre-
sents one specific type, or two or more very
closely related types; in fact, the signifi-
cance of an ecological study may depend
directly on allied taxonomic relationships.
Certain phases of the intermediate field
between taxonomy and genetics I discussed
two years and more ago in this city before
the American Philosophical Society, and
suggested a definite program of combined
systematic and experimental work; there-
fore I shall not enlarge on this subject here,
although it merits further attention. It
may be noted in passing, however, that the
more enthusiastic definition of forms de-
mands a refined and more exact art of
phytography, and it should lead also in the
direction of classification. The marked
variations may well find place in a taxo-
nomic treatment rather than to be studied
merely as separates. The remarkable mu-
tations of Nephrolepis, for example, af-
ford excellent material for systematic de-
seriptive study.
Much of the earth is yet to be explored
for the forms of life. There are fertile re-
gions yet untouched. One collection in
Papua yielded some 1,100 new orchids.
Remarkable collections of novelties con-
tinue to come to our herbaria, many of
them from regions not very remote. Not
nearly all the plants of the globe are
known. The systematist must continually
be better trained, for he has the task of
understanding the older accumulations as
well as adjudging the new. He makes in-
ereasing contributions to plant geography
and distribution, and gives us an enlarged
judgment on the character of the countries
of the earth as indicated by their vegeta-
tion. In fact, we never understand a coun-
try before we know its plant life. The con-
tributions made recently by Forrest, Wil-
son, Purdom and others to the geography
626
and resources of western China are good
examples.
Yet it is in the old regions as well as in
the new that novelties still come to the
hand of the systematist. Every edition of
the manuals of the plants of the northeast-
ern United States, for example, contains
large additions. These acquisitions are in
some part the result of new introductions,
running wild; in an important part the dis-
covery of species heretofore overlooked; in
large part, also, the results of redefinition,
known as ‘‘splitting’’ of species.
This splitting is not alone the result of a
desire to ‘‘make new species,’’ but is the
operation of a new psychology. In every-
thing we are rapidly becoming particu-
larists. In the time of Gray we studied
plants as aggregates, trying to make them
match something else; now we study them
as segregates, trying to make them differ
from everything else. This diversity in
process accounts for the extension of
(@nothera, Carex, Rubus, Malus, Crategus.
Whatever may be said of the relative ranks
of the newly described species in a scheme of
coordination, we should thereby neverthe-
less understand the forms better than here-
tofore and refine both our discrimination
and our definition. Probably we do not yet
really understand any one of the more rep-
resentative genera of plants of the north-
eastern United States.
In making these remarks I am not com-
mending the practise of those who would
divide and redivide minutely, and who
would carry descriptive botany to such a
point of refinement that only the close
specialist can know the forms. Under
such circumstances, systematic work de-
feats its own ends.
It is, after all, to the plants of the older
lands that the systematist must constantly
bring his closer observation, new meas-
urements, accumulation of facts, keener
SCIENCE
[N. S. Von. XLVI. No. 1200
judgments, truer interpretation of environ-
ment, profounder estimation of relation-
ships that can be expressed by classifica-
tion. He is not merely a deseriber of
novelties, giving new names; he discrimi-
nates, re-defines, applies the results of latest
collateral science, suggests new meanings.
His studies, as any others, must be kept
alive and up to date. He must continually
better serve any student of plants. There
is no more end to the work of the systema-
tist than to that of the geneticist.
Every large or variable group needs to
be reworked at least every twenty-five
years. In fact, it is an advantage to have a
group worked simultaneously by separate
monographers, that we may have more
than one method and more than one judg-
ment brought to bear on the problem. We
must outgrow the idea that there is any
finality in even the best monograph. Fre-
quent review and sifting of evidence are as
necessary in systematology and taxonomy
as in morphology.
We do not realize that there is now ap-
pearing the modern systematist, who is not
an herbarium hack, but a good field man,
an evolutionist and plant geographer, one
highly skilled in identification, and rein-
forced by much collateral training of a
highly specialized character. This man
has come quite unaware to most of us.
Among the phytographers are those who
are primarily cataloguers, sorters and bib-
liographers, of great skill; but the real
systematist is a highly trained scientist.
I regret that the contribution of this man
is frequently so little evidenced in the proc-
esses of college teaching. Graduates may
be sent forth to instruct in botany so inno-
cent of kinds of plants and of the means of
finding them out as to be lost when placed
in a strange country, wandering blankly
among the subjects they are supposed to
teach.
DrceMBeER 28, 1917]
I have said that the systematist is spe-
cially needed in the older lands. I wish
now to press this remark still farther by
saying that he is much needed in the oldest
and best known genera. What are known
as the older species, as well as older genera,
are likely to be least understood, for knowl-
edge becomes traditional and they pass un-
challenged. It is exactly in the old and
supposedly well-known species that we are
now making so many segregates.
It may be difficult, in any given monog-
raphy, to express these different aptitudes
of the systematist. Some subjects or prob-
lems do not exhibit the features that I have
suggested nor admit of the application of
such broad and deep investigations, even
though the study and publication of them
may be very much worth doing. Yet, the
field of systematic work may be indicated,
as an aim.
THE SITUATION IN THE CULTIVATED FLORA
No plants go unchallenged so completely
as those of widespread, common and an-
cient cultivation. The treatment of them
is particularly traditional.
no ‘‘types’’ representing them in herbaria.
Origins may be repeated, perhaps even from
the days of the herbalists. Statements are
passed on from book to book and genera-
tion to generation. The plants are taken
for granted. Yet when we come to study
them eritically we find that they may con-
tain ‘‘new species,’’ those that have passed
all this time unrecognized. Any field that
has been long neglected is sure to yield new
harvests. The cultivated plants now pro-
vide some of the best botanizing grounds.
A few examples will illustrate what I
mean. As a very simple illustration I may
cite the case of the plant cultivated as
Malvastrum capense. The species (as
Malva capensis) was founded by Linneeus.
The description in the books has been cor-

rect; but when the horticultural material
was critically examined in 1908 it was found
be an unrecognized new species, although
cultivated for more than a century. It is
now uamed WMalvastrum hypomadarum
Sprague. Another new species has re-
cently been separated by Sprague in the
material commonly grown in greenhouses
as Manettia bicolor. The cultivated stock
is clearly of two species, M. bicolor being
Brazilian, and the new WM. iflata being
Paraguayan and Uraguayan. A case may
be cited also in one of the commonest
abutilons. The plant grown as A. striatum
Dicks, is found to be really A. pictum
Walpers, with the true A. striatum prob-
ably not in cultivation; and part of the
greenhouse material, long cultivated, was
separated as a new species, A. pleniflorum,
as late as 1910 by N. E. Brown. Moreover,
the plant still grown as A. Thompsoni is
found to be not that plant, the material
now cultivated in England under that name
being recently described as A. striatum var.
spurium, and that in America being appar-
ently of several unidentified forms. In the
meantime, the original A. Thompsonii ap-
pears to have been practically lost. Now,
this situation directly involves the integ-
rity of the so-called bigeneric graft-hybrid
Kitaibelia Lindemuthii, one of the parents
of which is recorded as Abutilon Thomp-
soni.
These are cases of erroneous determina-
tion and of confusion in forms, representing
one of the commonest kinds of puzzles in
the study of cultivated plants. The diffi-
culty lies in the fact that systematists have
not taken the trouble to look the cases up,
accepting the plants from literature, and
also in the fact that herbaria usually do
not adequately represent such plants. The
student may search in vain for authori-
tative early material of most long-culti-
vated plants, even in the best herbaria.
628
One of the present necessities is to collect
the cultivated plants in their different
forms from many localities, and repre-
senting the stocks of different dealers, in
precisely the same spirit in which feral
plants are taken for herbaria. Without
such sourees of information, we can neither
understand the systematology of the plants
themselves or bring the best aid to the stu-
dent of heredity.
[The speaker here mentioned the lack of
record material in studies of the systema-
tology of Coleus and other groups; and ex-
plained also the unsatisfactory practise on
which descriptions of large numbers of cul-
tivated species still must rest.]
Excellent illustration of the confusion in
cultivated plants, even of relatively recent
introduction, is afforded by the velvet-
beans now grown in the southernmost states.
These plants have been referred indiscrim-
inately to Mucuna pruriens, long cultivated
in the tropics. On careful recent study,
however, the American planted material is
found to be so different from Mucwna as
to necessitate generic separation, and the
genus Stizolobium has been revived to re-
ceive it. The common cultivated velvet-
bean is found by Bort to be an undescribed
species, probably of oriental origin, and it
has been named and described Strzolobiwm
Deeringianum. Subsequently other species
have been newly described in the cultivated
stocks. One need not go far for many
comparable illustrations of the confusion
in which eultivated plants have lain.
Americans are now specially active in re-
solving these complexities. As a running
random comment may be cited the work of
Rose in the cacti, Swingle in Citrus, Rehder
in Wisteria, oriental Pyrus and others,
Wilson in Japanese cherries, Safford in
Annonacee. It is not too much to say that
any of the important groups of cultivated
SCIENCE
[N. 8. Von. XLVI. No. 1200
plants will fall to pieces as soon as touched
by the competent modern systematist.
The systematist who works in these do-
mesticated groups must first make large
collections of new information and mate-
rial. It is becoming a habit with him to
travel extensively to study the plants in
their original countries, and to bring his-
tory and ethnography to bear on the prob-
lem. He is not content until he arrives at
sources.
[The speaker discussed, and illustrated
with herbarium material, the recent studies
in the cultivated poplars, whereby the sub-
ject has been opened for discriminating in-
vestigation. |
Nor does the confusion lie only with
plants of ancient domestication or with
those native to countries which have not
yet been well explored. The horticultural
blackberries have been brought into eulti-
vation from American wild stocks within
seventy-five years or less, they have been
accorded careful study by several special-
ists, yet no one is ready to name the spe-
cies from which the different forms have
come. A number of systematists are work-
ing on them, and yet they are in need of
further study, both in the wild and in culti-
vation. In Prunus is a comparable ease,
horticultural forms in many named vari-
eties of native plums having come into ecul-
tivation within fifty years. It fell to my
hand to attempt the first critical taxonomic
writing of these native plants, in 1892; but
in 1915 Wight completely recast the treat-
ment, in the light of accumulated experi-
ence. This illustrates my earlier remark
that every group should be newly mono-
graphed at frequent intervals.
Perhaps we do not sufficiently realize
the great numbers of species of plants now
in cultivation. We may have in mind the
247 species studied by DeCandolle in his
DECEMBER 28, 1917]
“Origin of Cultivated Plants.’’? These are
only food plants, and the treatment does
not pretend to be complete. In the Stand-
-ard Cyclopedia of Horticulture, the entries
of plants described in cultivation exceeds
20,000, although not nearly all these spe-
cies are domesticated. About 40,000 Latin
names are accounted for. This treatment
does not cover the cultivated plants of the
world, but those of the United States and
Canada and those readily drawn from the
European trade, with the most prominent
species in the island dependencies of the
United States. Probably never have spe-
cies new to cultivation been introduced so
rapidly as within very recent years. For
example, in the treatment of Primula in
the Cyclopedia of American Horticulture
in 1901, I described twenty-seven species ;
in the Standard Cyclopedia in 1916, I de-
seribed 200. All this phalanx comprises in
itself a large section of the vegetable king-
dom, perhaps as much as nearly one sixth
of the Spermatophyta, and it demands
the attention of the best phytographie and
taxonomic investigation.
The long-repeated statements of origins
of cultivated plants are challenged when-
ever the systematology is seriously attacked,
or when the subject is examined under bo-
tanical investigations. The case of maize
is a striking example; although always
explained on the basis of American origin,
the reported pre-Columbian references in
China need further investigation. The
same kind of puzzle associates with many
plants, wild as well as domesticated, that
are prominent subjects in early travels
and writings. Thus Fernald concludes
that the wine-berries of the Norsemen were
not grapes found on the shores of the pres-
ent New England, as we have always as-
sumed, and that they were probably moun-
tain cranberries found in Labrador or the
SCIENCE
629
St. Lawrence region. The result of con-
temporaneous studies is that, from both the
historical and biological sides, the founda-
tions are being shocked. Most of my life I
have given special attention to the botany of
the domesticated flora, yet I should not now
care to hazard a pronouncement from this
platform on the specific natural-history
origin of any one of the more important
widespread species of cultivated plants.
THE SYSTEMATIST IS A BIOLOGIST
Whether he works with feral or domestic
floras, the systematist of whom I speak is a
real investigator. He studies the living
material so far as he is able, perhaps grow-
ing it for this purpose; tries to understand
the influence of environment, the rdle of
hybridization and mutation, and preserves
his records in the form of ample herbarium
sheets. He relates his work to morphology,
and desires to arrange it as an expression
of lines of development. He may study
his material for years before he ventures
to describe. It follows that the systema-
tist necessarily, in these days, becomes a
specialist; and it further follows that we
should encourage, in addition to the few
very large and comprehensive establish-
ments, the making of many herbaria and
growing collections strong in special lines.

PATENT REFORM PROSPECTS
Tue Patent Office Society is permitted to
announce that a composite committee has been
created, upon request, by the National Re-
search Council, to make a preliminary study
of the problems of the U. S. Patent Office and
its service to science and the useful arts. This
committee, which is expected to meet in Wash-
ington shortly after the middle of December,
is understood to comprise, at the outset, the
following: Leo H. Baekeland, Wm. F. Durand,
Thos. Ewing, Frederick P. Fish, Robert A.
630
Millikan, Michael I. Pupin and 8. W. Strat-
ton.
The action of the National Research Coun-
ceil in forming a committee of this sort is
understood to be in conformity with the
wishes of Commissioner of Patents J. T. New-
ton and Secretary of the Interior F. K. Lane,
and to be in accord also with the following
resolutions originally adopted by the Patent
Office Society and concurred in by Mr. Ewing
while commissioner of patents:
WHEREAS a section of the charter of the Na-
tional Academy of Sciences provides that ‘‘The
academy shall, whenever called upon by any de-
partment of the government, investigate, examine
and report upon any subject of science or art,’’
AND WHEREAS, at the request of the President of
the United States, the academy has organized a
National Research Council, to bring into effective
cooperation existing governmental, educational
and other research organizations,
AND WHEREAS the National Research Council is
now perfecting its organization for the perform-
ance of the above duties,
AND WHEREAS a fundamental activity of the
Patent Office is research upon questions of novelty,
‘“in order to promote the progress of science and
the arts’’ by the prompt issuance of proper grants
and the refusal of improper grants of patent
monopolies,
Now therefore be it resolved by the Patent
Office Society:
1. That in its judgment a request for coopera-
tion, advice and assistance should be promptly
forwarded to the National Research Council, at-
tention being called to such problems as ade-
quacy of force, adequacy of space, adequacy of
library, adequacy of facilities for test and dem-
onstration, adequacy of classification, adequacy of
organization, adequacy of scientific, legal and pro-
fessional standards, adequacy of incentives and op-
portunities, simplification of procedure, responsive-
ness to present national and international re-
quirements and to the important advances that
might be expected either from an independent
study of the above by the National Research
Council or from an early effort on its part to co-
ordinate, in the interest of an improved public
service, the endeayors of the various national so-
cieties, manufacturing interests, patent bar asso-
ciations, and all others aiming at genuine pat-
ent reform.
2. That the coneurrence of the Commissioner of
SCIENCE
[N. S. Vou. XLVI. No. 1200
Patents and the Secretary of the Interior in these
resolutions be solicited.
3. And that a copy hereof be forwarded to the
National Research Council with some expression of
the appreciation of this society for the interest
already shown, and some appropriate assurance of
the determination of this society to render every
possible assistance and support to the work of the
National Research Council.
The implied determination of the Patent
Office Society to do its part in an effort to
improve the work and conditions of the Pat-
ent Office, and to gain therein all possible sup-
port on the part of scientists, engineers and
manufacturers, is further indicated in the ac-
companying resolutions relating to the pro-
posed Institute for the History of Science, for
which a Washington location is by it advo-
cated—this latter proposal being already ac-
corded the invaluable support of the Wash-
ington Academy of Sciences.
RESOLUTIONS ADOPTED BY THE PATENT OFFICE SO-
CIETY, BY ITS AUTHORIZED EXECUTIVE
COMMITTEE
That the attention of all interested in the
possibilities of the proposed Institute for the His-
tory of Science be ealled to the advantages of
such a location and organization for that insti-
tute, whenever it shall be established, as shall
render its resources easily available not only to
highly trained specialists but also to practising
engineers, to examiners of patents, and, so far as
practicable, to the general public.
That, in the judgment of the Patent Office So-
ciety, the present moment of prominence of
American ideals and of recognized dependence
upon the facts and principles of science is none
too early for preliminary steps toward the estab-
lishment in this country of an Institute of the
general character already proposed (by George
Sarton, and others, in Science, March 23, 1917),
such institute to be independent, liberally endowed
and adequate not only to the requirements of our
present national life, but also to that great era of
internationalism and general enlightenment upon
which even the avoidance of war may hereafter
depend.
That the special committee in hand relations
with the National Research Council be directed to
emphasize to that body the foregoing conclusions
as perhaps pertinent to purposes shared by it; to
DEcEMBER 28, 1917]
solicit the concurrence therein of both the local
and the national scientific and engineering so-
cieties, and to publish the same generally, or in
its diseretion, always with careful regard to the
aims of those to whom the project is due.
The following questions raised in a report
made to the Patent Office corps by a special
committee charged to cooperate with the per-
sonnel committee of the National Research
Council will indicate something of the tend-
ency of measures for which it is hoped to
gain early consideration:
What does the Patent Office need besides men
and materials?
Feeling that the time is at hand when the Pat-
ent Office must enter upon either a period of very
rapid decline or else upon a period of revitaliza-
tion and expansion, shall we not test the notion
that it may actually be easier, and in every re-
spect better, for the office, exhibiting a new vi-
sion of its task, to ask a great deal more, rather
than to continue its petition for the very, very
little that has so often been denied it?
Relying upon the assistance of the composite
committee generously formed by the National Re-
search Council—
Can assistance be got, even now, in the making
of a genuine advance in the indispensable work of
reclassification of patents and of literature?
Can all who are employed in the work of exami-
nation be in any way further encouraged and aided
to become specialists in one or another of the
branches of applied science—rather than mere
rule-parrots and picture-matchers? And would a
proposed departmental organization of the office
aid to this end?
Can these gains against dilatory prosecution ,
made under the energetic efforts of Commissioner
Ewing be rendered secure for the future by (e. g.),
dating the terms of patent monopolies from the
date of filimg—in order to create an incentive for
diligent rather than dilatory prosecution?
Could any adjustment of extra fees for extra
claims discourage the ‘‘fog-artists’’ and create an
incentive for a more genuine effort on the part of
attorneys to find the meat of the coconut—instead
of putting it up to the office, the courts or the pub-
lie to do so?
Can any elevation of the standards of practise
(effected perhaps with the assistance of the pat-
ent bar) relieve the office at the same time from an
undue burden of editorial work and from any
suspicion of complicity in the wholesale netting of
SCIENCE
631
““suckers’’ by men who indulge in misleading ad-
vertisements or contingent prosecution?
Can the divisions of the office advantageously be
grouped into departments, each comprising sev-
eral divisions handling analogous problems—a
chemical department, an electrical department, an
“‘instrument’’ department, a motive power de-
partment and the like, each under some expert of
distinction in a particular field, and this body of
experts having not only authority within their re-
spective departments, but exercising collectively
an enlightened and final appellate jurisdiction?
Can the salaries of these proposed department
heads (constituting an enlarged and strengthened
board) and the salaries of chiefs of divisions, and
of others, be made such as to justify able and
provident men in remaining for a much longer
average term within this branch of the service?
Could the establishment in Washington of some

WARTIME WORK OF THE FOREST SERVICE
How the work of the Forest Service was
realigned to meet war conditions is described
in the Annual Report of the Forester, which
in the absence of the head of the service is
made by Acting Forester A. F. Potter. The
report also states that practically every form
of use of the forests was greater than ever
before, that the receipts again touched a new
high level with a total of $3,457,028.41, and
that the increase in receipts over the previous
year was $633,487.70.
“When the grazing charge has been ad-
vanced to cover the full value of the grazing
privilege,” says the report, “the income from
the national forests will be close to the cost
of operation. The present annual cost is
about $4,000,000.” An increase equal to that
of the last fiscal year “‘ would close the gap.”
The Forester, Henry S. Graves, is now
serving with the American Expeditionary
Forces in France, with a commission as lieu-
tenant colonel, in connection with the forest
’ work for the supply of the needs of our over-
seas troops and those of the Allies. A num-
ber of other members of the Forest Service
reeived commissions in the Tenth Engineers
(Forest) while many more entered the ranks.
Wood and other forest products have al-
most innumerable uses in modern warfare.
Never before has the demand for exact knowl-
edge been so urgent. “In the work relating
to forest utilization and forest products, the
resources of the service have been employed to
the limit of their capacity since the war be-
gan in rendering assistance to the War and
Navy Departments, the Emergency Fleet
Corporation, various committees of the Coun-
DrcEeMBER 28, 1917]
cil of National Defense, and manufacturers
of war orders. The peace-time program has
been largely discontinued. The force and the
work have been centered in Washington and
Madison. Every effort has been made to
bring available knowledge to the attention of
the organizations which have need for it and
to assist in anticipating their problems.”
Much of the work has concerned aircraft
material. It has included also problems con-
nected with the construction of wooden ships
and of vehicles. Assistance has been given
to hardwood distillation plants in order to in-
crease the production of acetone and other
products needed for munition making. A
commercial demonstration has shown that
eosts of producing ethyl alcohol from wood
waste can be materially reduced. Methods
have been developed by which walnut and
birch can be kiln-dried in a much reduced
time with comparatively little loss. In gen-
eral, the report says, “much assistance has
been given on a great variety of war problems
relating to forest resources and the manu-
facture, purchase, and most efficient use of
wood and other forest products.”
Tn spite of the many new demands upon the
Service and the entrance upon military duties
of a considerable number of its men, the ad-
ministrative and protective work on the na-
tional forests was continued without disor-
ganization. “Upon request of the War De-
partment the preliminaries of recruiting and
officering the Tenth Engineers (Forest) were
handled. Increase of crop production in and
near the forests was stimulated and the forage
resource of the forests was made available for
emergency use up to the limit of safety. In
the latter part of the summer a fire season of
extreme danger, made worse in some localities
by an unusual prevalence of incendiarism,
was passed through with relatively small loss
of property and with no reported loss of life.”
WAR ACTIVITIES OF THE GEOLOGICAL
SURVEY
THE activities of the Geological Survey, De-
partment of the Interior, during the fiscal year
1916-17 have been concentrated on investiga-
tions connected with military and industrial

preparedness, as shown by the Annual Report
of the director of the survey, just made public.
These activities have included the preparation
of special reports for the War and Navy De-
partments and the Council of National De-
fense, the making of military suveys, the print-
ing of military maps and hydrographic charts,
and the contribution of engineer officers to the
Reserve Corps.
The survey’s investigations of minerals that
have assumed special interest because of the
war have been both expanded and made more
intensive. Special reports giving results al-
ready at hand, the product of years of field
and office investigation, have been published
for the information of the general public or
prepared for the immediate use of some official
commission, committee or bureau. Geologic
field work has been concentrated on deposits of
minerals that are essential to the successful
prosecution of the war, especially those of
which the domestic supply falls short of pres-
ent demands. Every available oil geologist is
at work in petroleum regions where geologic
exploration may lead to increased production.
Other geologists are engaged in a search for
commercial deposits of the “war minerals ”—
manganese, pyrite, platinum, chromite, tung-
sten, antimony, potash and nitrate.
The war not only diverted practically all
the activities of the topographic branch of the
survey to work designed to meet the urgent
needs of the war department for military
surveys, but led to the commissioning of the
majority of the topographers as reserve officers
in the Corps of Engineers, United States
Army.
A large contribution to the military service
is made by the map-printing establishment of
the survey. This plant has been available for
both confidential and urgent work, and during
the year has printed 96 editions of maps for
the war department and 906 editions of charts
for the navy department. Other lithographic
work, some of it very complicated, was in
progress at the end of the year.
During the year the survey published 203
scientific and economic reports, and at the end
of the year the survey members holding ap-
634
pointments from the secretary numbered 934,
an increase of 62.
SCIENTIFIC NOTES AND NEWS
Tue American Association for the Ad-
vancement of Science begins its annual meet-
ing at Pittsburgh on the day of issue of the
present number of Science. The address of
the retiring president, Dr. Charles R. Van
Hise is given this evening, his subject being
“Economie Effects of the World War in the
United States.” It is expected that the meet-
ing of the association and of the national
societies meeting at the same time will be
smaller than usual, and that scientific prob-
lems of national concern at the present time
will occupy most of the programs. Careful
consideration was given to the desirability of
holding the meeting. It. was decided that the
service it could render to science and the
nation was far greater than any drawbacks.
This was the opinion both of scientific men
and of the officers of the government who
were consulted.
Sm ArcHIBALD GEIKIE, who. has long been a
correspondent of the Paris Academy of Sci-
ences, has now been elected an associate mem-
ber of the academy.
Dr. WituiamM W. Keen, of Philadelphia, has
declined the renomination of president of the
American Philosophical Society, after serv-
ing ten years in that capacity.
Dr. ALEXIS CarREL, having been detained in
America by official duties, the Harben lec-
tures he was to have delivered in England at
the end of this month have been postponed.

mano-Austrian group shall receive his share,
but that the shares belonging to members of
other nations shall be retained and applied to
some object of scientific reparation in Belgium.
The meeting then determined that a new so-
ciety shall be formed after the war on a basis
similar to that of the Société Internationale de
Chirurgie. It will be called the Société In-
teralliée de Chirurgie, but will be open also to
such surgeons of neutral countries as may be

Dr. F. W. Cuiarke, chairman of the Interna-

in the Journal of the American Chemical So-
ciety that on account of the difficulties of
correspondence between its members, due to
the war, the International Committee on
Atomic Weights has decided to make no full
report for 1918. Although a good number of
new determinations have been published dur-
ing the past year, none of them seems to de-
mand any immediate change in the table for
1917. That table, therefore, may stand as
official during the year 1918.

THE chief signal officer requests that help
be given to the Signal Corps of the army to
obtain lenses enough for cameras for the fleet
of observation airplanes now being built. The
need is immediate and of great importance;
the airplanes are the eyes of the army and
the camera lenses are the pupils of those eyes.
German lenses can no longer be bought in the
open market. England met this difficulty in
the earlier stages of the war by requiring lens
owners to register lenses and requisitioning
those needed. The Bureau of Standards of
the United States Department of Commerce
is now perfecting a substitute for the German
“crown barium” glass used for lenses and
will later be able to meet the needs, and
special lenses are being designed for this work.
The situation now, however, is that, with air-
planes soon to be ready for service, suitable
lenses can not be bought. Hundreds are
needed at once. Possessors of the required
types are urged to enlist their lenses in the
army. They are asked immediately.to notify
the photographie division of the Signal Corps,
United States Army, Mills Building Annex,
Washington, D. C., of lenses of the following
descriptions which they are willing to sell,
stating price asked: Tessar anastigmat lenses,
made by Carl Zeiss, Jena, of a working aper-
ture of F. 3.5 or F. 4.5 from 83 to 20 inches
focal length. Bausch & Lomb Zeiss tessars,

637
establishment of a new mining experiment sta-
tion under the jurisdiction of the school of
mines at the University of Minnesota. Min-
nesota is one of two institutions to be so desig-
nated. The other bureau was established at
Columbus, Ohio, the recognized center of the
elay-working industries of the United States.
In recommending the University of Minne-
sota to Secretary Lane for the site of one of
the proposed stations, Director Manning, of
the bureau, said that at the present rate of pro-
duction the high grade ores of Minnesota will
become almost exhausted the next thirty years
and it will be the duty of the bureau to en-
deavor to show the way to utilize the huge de-
posits of low-grade ores if the industry is to
continue to prosper. The station is to work
in a cooperative way with the University of
Minnesota, an agreement to that effect having
been signed by both parties.
Durine the past summer, Professor C. H.
Edmondson, of the department of zoology of
the University of Oregon, has been conducting
a survey of the shellfish resources of the north-
west coast, under the direction of the U. S.
Bureau of Fisheries. The survey is a part of
the general conservation of food campaign
undertaken by the federal government. In the
course of the work the coast of Oregon has
been traversed from about five miles south of
Bandon to the mouth of the Columbia River
and the Washington coast north to Gray’s
Harbor. All the important bays and inlets
were visited and the species and relative abun-
dance of the edible clams noted. The purpose
of the survey, however, is not merely to de-
termine the location of the edible shellfish, but
to aid in all possible ways the increase of this
type of food supply and to encourage the
general public to make greater use of clams
and mussels as a partial substitute for the
higher priced meats. Few realize the abun-
dance of food represented by the immense
quantities of shellfish distributed along this
coast or how cheaply edible clams may be
obtained from the towns of Marshfield, Flor-
ence, Newport or Tillamook. In view of the
fact that little is known of the life history of
any of these shellfish of our coast, Professor
638
Edmondson has initiated experimental work at
Florence, Newport and Tillamook for the pur-
pose of determining the rapidity of growth,
the age, the spawning season and the condi-
tions under which certain of the edible clams
best thrive. These experiments will be carried
on throughout the year or until satisfactory
results are obtained.
A QUESTIONNAIRE was recently circulated
among the members of the Chartered Institute
of Secretaries of Great Britain for the pur-
pose of obtaining opinions in regard to the
adoption of a decimal system of coinage in
the United Kingdom, and the substitution of
the metric system for the existing United
Kingdom weights and measures. Of the re-
plies received 85 per cent. considered that a
change to a decimal system of coinage would
be favorable to the business in which they
were engaged, and 66 per cent. favored a £1
basis of coinage in preference to the “ Im-
perial Crown” or dollar basis. In regard to
weights and measures, 86 per cent. favored a
change to the metric system, 53 per cent. of
whom already used that system in their busi-
ness. One member expressed the opinion that
a strong commission of able men should be
asked to’ decide whether the continental sys-
tem, which was forced upon countries at a
time when violence, rather than reason, pre-
vailed, had been really satisfactory.

DISCUSSION AND CORRESPONDENCE
THE PITTSBURGH MEETING OF THE AMERI-
CAN ASSOCIATION FOR THE ADVANCE-
MENT OF SCIENCE
[The following letter was delayed in the
mails and reached ScrENcE just too late for
publication in the last number. ]
To THe MemBers OF THE AMERICAN ASSOCIA-
TION FOR THE ADVANCEMENT OF SCIENCE:
Wuen the American Association for the
Advancement of Science and all similar so-
cieties planned their winter meetings, the
present situation could not have been fore-
seen. We had not even entered the war, and
did not dream of a congestion of transporta-
tion such as now exists. When the present
situation had developed, it was (in the opin-
ion of a majority of the committee having
power) too late to postpone our meeting.
Transportation is now so greatly overtaxed
that necessaries of life can barely be carried;
the railways should be spared every extra
burden. Great simultaneous pilgrimages on
important trunk lines are especially to be
avoided, since they demand extra trains, need-
DECEMBER 28, 1917]
ing extra locomotives and coal, and causing
much confusion. Therefore, in my opinion it
behooves every patriotic and unselfish mem-
ber ‘to consider very seriously whether he can
really serve his country by attending the
meeting, or whether he can not better serve
in this fateful time by staying at home, espe-
cially during a period of highly congested
travel, when many of our soldiers may wish
to take leave of their families before departing
for the front. I believe that only those persons
bringing really important contributions to
the problems of the war should attend such
meetings now. All others, in my opinion,
should conserve their money for Liberty
bonds and for those in distress, and should
save their strength for action in this time of
extraordinary crisis. For these reasons, with
great regret, I have decided not to attend the
meeting at Pittsburgh.
So far as I have been able to ascertain, all
the responsible authorities at Washington
concerned with transportation agree with me
as to the importance of avoiding unnecessary
journeys in such a crisis.
The very great usefulness of the American
Association for the Advancement of Science
is not dependent upon the unbroken continuity
of its social meetings.
Science is inealculably important, indeed
indispensable, in this world-wide cataclysm.
The excellent work of the association in the
past is now bearing fruit; but this moment
demands action rather than general discussion.
We must devote all our energies to winning
the war. Let us all make every endeavor to
apply our knowledge and strength in our
country’s noble cause.

THE BEARING OF THE FACTS REVEALED BY
ANTARCTIC RESEARCH UPON THE PROB-
LEMS OF THE ICE AGE?
Recent Antarctic explorations and _ re-
searches have yielded significant evidence re-

Great Ice Age of Pleistocene Time. He holds that
the occurrences of ice as a geologic agent of mag-

garding the problems of the Ice Age, and, of
the similarity of the succession of geological
climates in polar with those in other lati-
tudes.?
These researches have been prosecuted to
the ultimate limit of courage, devotion to duty
and enduranece—the noble sacrifice of lfe—
as in the cases of Captain Scott, R.N., and
his devoted companions and members of the
expedition of Sir Ernest Shackleton.
The data secured by these expeditions are
alone sufficient to establish the following
premises :
1. That Antarctic ice, although covering
areas several times larger than all other ice
covered areas, is slowly decreasing in extent
and depth.
2. That the same succession of geological
climates have prevailed in Antarctic as in
other latitudes.®
So vital are these evidences of the retreat
of Antarctic ice that it may be well to briefly
quote or refer to the most prominent in-
stances:
All these evidences and many others which
space will not allow me to mention lead up to
one great fact—namely, that the glaciation of the
Antarctie regions is receding.t
The ice is everywhere retreating.5
The high level morains decrease in height above
the present surface of the ice, the débris being
two thousand feet up near the coast and only two
hundred feet above near the plateau.

not ‘‘world wide’’ nor as ‘‘phenomenal,’’ nor were
they preceded, accompanied nor followed by con-
ditions as significant as corresponding phenomena
of the Ice Age. (Compte Renda du XI ieme Con-
grés Géologique International, p. 1105. Stock-
holm, 1910.)

This observation applies to an ice-covered
area of over 116,000 square miles.
Mr. Griffith Taylor notes the recession of
Dry Valley Glacier twenty miles from the sea
below Taylor Glacier.?
Mr. Taylor also notes and speaks with con-
fidence of the passage of the Ice Age from
Antarctica.8
In speaking of the evidence of ice retreat
over Antarctic areas explored by him, Sir
Ernest Shackleton said:
Some time in the future these lands will be of
use to humanity.9
This impressive and conclusive evidence is
corroborated by the greater and still more im-
pressive evidences of the comparatively recent
uncovering of temperate land areas,?° and the
progressive retreat of the snow line to higher
elevations in temperate and tropical latitudes
and towards the poles at sea level, being far
greater in Arctic than in Antarctic regions.
We are therefore confronted with the con-
clusions:
1. That the disappearance of the Ice Age is
an active present process and must be ac-
counted for by activities and energies now at
work, and that the use of assumptions and
hypotheses is not permissible;
2. That the rates and lines of retreat are
and have been determined by exposure to
solar energy and the temperatures established
thereby; and by the difference in the specific
heat of the land and water hemispheres;
3. That the lines of the disappearance of
ice are not conformable with those of its dep-
osition, and mark a distinctly different ex-

10 Slight fluctuations in the retreat of the small
residual glaciers in temperate latitudes are noted
in the reports of the Commission on Glaciers
of the International Geological Congress by
Professor Harry Fielding Reid. But the great
measures of the progressiveness of glacial retreat
are in the past disappearance of the Pleistocene
ice fields of temperate latitudes and the present
retreat in the Antarctic and Arctic regions.

posure and climatic control from that which
prevailed prior to the culmination of the Ice
Age.
4. This retreat also marks a rise in mean
surface temperature along these new lines,
manifestly due to recently inaugurated ex-
posure to solar radiation and also the inaugu-
ration of the trapping of heat derived from
such exposure; which process is cumulative
and has a maximum not yet reached.
The researches under the direction of Cap-
tain Seott and Sir Ernest Shackleton have
therefore very rigidly conditioned any inquiry
as to the causes of glacial accumulation and
retreat. These conditions are CORRECTIVE and
DIRECTIVE—corrective, in that they have en-
tirely removed any doubts as to the alternate
glaciation of the poles under the alternate
occurrence of aphelion and perihelion polar
winters by the precession of the equinoxes, as
advanced by Croll; directive, in that they
have imposed an appeal to energies now active
as causes of retreat, and divested the problem
of resorts to the fascinating but dangerous
uses of suppositions and hypotheses.
They have, moreover, pointed out with un-
erring accuracy the vital conclusion that the
same energies which have but recently con-
verted the glacial lake beds of Canada into
the most productive grain fields of the world
will in time convert the tundras of to-day
into the grain fields of to-morrow.14
The bearing of this conclusion upon the
ultimate development of the human race is
so far-reaching in its consequences that the
great sacrifice of life attendant upon the
prosecution of these researches stands forever
as a memorial in the correction of the erro-
neous and wide spread conception that the
earth is in a period of refrigeration, desic-
cation and decay; and establishes the con-
clusion that it is in the spring time of a new
climatie control during which the areas fitted
for man’s uses are being extended and that
the moss of polar wastes will be replaced by
rye and wheat. Marspen Manson

EFFICIENT LABORATORY LIGHTING
SEVERAL notes have appeared in Science the
past few years relative to the development of
glass through which a proper spectroscopic cor-
rection could be secured for microscopic pur-
poses. There are also on the market various
microscope lamps designed to furnish a cor-
rected artificial light for laboratory study.
These devices, though very satisfactory for
small advanced classes, are in many ways un-
desirable for large classes of elementary stu-
dents, and sitting, as they usually do, on the
laboratory table, are more or less subject to
breakage when used by large numbers of stu-
dents.
The dark winter days during a part of the
school year made it imperative that the large
classes in agricultural botany at Oregon Agri-
cultural College be provided with a light which
would yield relative daylight values with tem-
porary mounts and stained prepared sections.
This has been attained most efficiently by the
use of the General Electric Company’s Ivanhoe
Truetint Unit No. 748, known as the “ Noon
Sunlight” grade. This is a large, apparently
blue shade, designed to cover the high-power
nitrogen-filled Mazda lamp. Experience has
shown that one of these units suspended two
feet above the laboratory table and equipped
with a one-hundred-watt bulb gives a superior
light for four students. In this way, forty
students at one time are being handled with
ease on dark days, the illumination being
ample even for the high-power dry or the oil
immersion objectives.
The cost of the entire installation is ap-
proximately the same for four men as that of
the usual microscope lamp designed for one
person. To secure a fixture which would be
near the table without obstructing it for
laboratory work, the shade holders were sus-
pended by nickel chains from the ceiling over
the center of each table. The lack of rigidity
of the fixture thus equipped is of special ad-
vantage in the elimination of breakage.

SCIENTIFIC BOOKS
The Elements of the Science of Nutrition.
Third Edition. By Granam Lusk. Phila-
delphia, W. B. Saunders Co., 1917. Pp. 641.
It is sometimes said that the sciences and
the fine arts are international in the broadest
sense of the word; they do not recognize na-
tional boundaries or racial limitations. Ney-
ertheless a nation may well be concerned about
the accomplishments of its citizens in the pur-
suit of knowledge. “Knowledge once won,”
Gowland Hopkins has recently written in a
commendable essay on medicine and experi-
mental science, “is of no country; it is the
common guerdon of mankind; but he who
cares nothing as to where it grows seems to
lack an element of patriotism.”
From this standpoint American science
need not be dissatisfied with the contributions
which the workers in this country have made
to the study of nutrition in the past decade.
Lusk’s “Science of Nutrition,” which has
established itself as a stimulating and com-
prehensive text-book, discloses the names of
more than one hundred American investigators
whose labors have helped, probably in larger
measure than those of any other country, to
bring new facts and permit new viewpoints in
nutrition during the interval that has elapsed
since the earlier (1909) edition of the book.
Its size has been expanded from 400 to 600
pages not by the mere accretion of incidental
observations but by the addition of carefully
considered novelties which the later develop-
Ment seems to warrant as worthy of consid-
eration.
The style and mode of treatment of the
problems of nutrition remain essentially un-
changed in the new edition. The historical
method has been followed in a way that can
not fail to interest those who are more fa-
miliar with the subject-matter, and that ought
to enthuse the beginner. There is something
almost inspiring in following the story from
its beginnings in the days of Lavoisier down
to the ingenious contrivances for respiration
study and calorimetry so highly developed in
the university laboratories and research in-
642
stitutes of the United States. A special new
chapter is devoted to some of this modern
technique that has furnished such helpful
measurements of the basal metabolism of man
and the domestic animals.
The novelties must be sought on every page;
for the new edition is not an expedient of
bookmaking but a record of progress. Among
the major accessions are elaborate discussions
of the possible processes of intermediary meta-
bolism. To those who learned their physiology
with a former generation the newer chemical
language may seem almost incomprehensible.
But Lusk properly remarks (p. 175): “One
must know the life history of sixteen amino-
acids in order to be familiar with the meta-
bolism of protein. Though the extension of
knowledge may have been at the cost of
simplicity, yet order is being wrought out of
apparent complexity. It is often difficult for
an older generation to think in terms of the
knowledge of a new. The author’s father was
a student at Heidelberg at the time when the
modern chemical formule were introduced,
when H—O became H,O, and he recalled the
distracted exclamation of one of the univer-
sity professors, ‘Ach Gott! wie kann man so
lernen!’”
A new chapter on The Nutritive Value of
Various Materials used as Foods develops the
history of the latest standpoints which are
threatening to upset so many of the currently
taught doctrines. “It is evident from the
material presented in this chapter,’ Lusk
writes (p. 878), “that the science of nutrition
- includes something more than the production
of energy from fat, carbohydrate and protein.
There must be certain salts and certain quali-
ties of protein in the diet, and there must be
minute amounts of ‘vitamins.’ The chemical
composition of the latter will some day be
known, even as the chemical composition of
epinephrin is known. -Epinephrin, an essen-
tial of life, is present in the blood to the ex-
tent of 1 part in 100,000,000. In like manner,
vitamins which are present in meat, milk,
fresh green vegetables and grains are essential
to the harmonious correlation of the nutritive
functions of animals.
SCIENCE
[N. S. Von. XLVI. No. 1200
Nephritis, cardiac disease and other condi-
tions involving acidosis are also considered in
their relation to metabolism. A highly inter-
esting and exceptionally timely chapter on
Food Economies concludes the volumes. A
few brief excerpts will suffice to indicate some
of the attitudes of the author.. After urging
the sale of food by calories and not by pounds
Lusk adds (p. 569): “ The main objection that
has been encountered to the sale of food on
the calorie basis has been the sensitiveness of
the business world to the introduction of a
new and unknown quantity. Why not leave
well enough alone? A more highly educated
generation will, however, demand that its ex-
penditure of thousands of millions of dollars
for food shall not continue to take place in
unfathomable depths of darkness.” Again (p.
571): “The housewife should know about
cooking, and both she and her husband should
know something of the value of food. The
sum wasted for alcoholic beverages would fre-
quently be sufficient to turn the scale in favor
of the proper nutrition of the family. Cheaper
milk for the babies of the poor and adequate
nourishment for school children are important
factors in the situation. . : . As this book goes
to press it seems that America herself is cer-
tain to face a food shortage before very long.
This can be remedied by increasing the num-
ber of milch cows and by reducing the live-
stock raised for meat. The latter would free
arable land for the production of grain and
potatoes and save, for human consumption,
grain fed to steers. It is quite certain that
meat in the quantity it is consumed to-day is
entirely unnecessary, and it is susceptible of
scientific proof that mechanical work is more
efficiently and economically derived from car-
bohydrate food than from meat.”
When the author expresses his conviction
that “in another decade the development of
scientific knowledge will probably permit the
formulation of the subject from the stand-
point of physical chemistry” the reviewer is
less sanguine regarding the complete domi-
nance of a single mode of attacking the prob-
lems of nutrition. Against the author’s pub-
lished statement that he has no intention of

being heard even from across the Atlantic.

Dr. A. G. Ruthven, the Director of the
Museum of Zoology of the University of Mich-
igan, is heartily to be congratulated upon the
appearance of the first volumes of these “ Oc-
easional Papers.” Nowadays when every one
is continually receiving requests to subscribe
to some new journal or other, this series
comes as a refreshing delight; it is not pub-
lished for sale! We learn that the papers are
issued separately to libraries and specialists,
and, when sufficient matter has accumulated,
a title page and an index—an excellent index
by the way—is prepared and the volume is
sent forth.
The contents will appeal especially to the
modernized systematist, who tries, at any rate,
to take interest in ecology, zoography and the
careful noting of life histories. We find
notices not only of such astonishing novelties
as Lathrogecko, Pseudogonatodes and Callis-
cincopus among reptiles, and of Crypto-
brachus and Geobatrachus among amphibia,
but of more general interest are the very in-
teresting observations upon the egg-laying
and hatching of several South American spe-
cies of amphibia, of varied genera, in all of
which some significant and peculiar adaptation
or modification is recorded. The series is not,
however, for the herpetologist alone. Reig-
hard and Cummins have a model description
of a new Ichthyomyzon with notes and fig-
ures of its appearance and customs. Other
writers discuss crustacea, insects of various
groups, trematodes, as well as birds and mam-
mals.
That these articles were not chosen for the

output for this comparatively new and hitherto
little-known museum indeed augurs happily
for the future of the series and for that of the
museum as well. Workers in the Museum of
Comparative Zoology at Harvard are perhaps
naturally more sympatico than others and
when they review their own museum’s past it
is not difficult for them to foresee the swift
growth of another great university museum
of similarly unrestricted interest and endeavor
at Ann Arbor.

SPECIAL ARTICLES
CONCERNING THE INFLUENCE OF THE AGE OF
AN ORGANISM IN MAINTAINING ITS
ACID-BASE EQUILIBRIUM
THE importance of the maintenance on the
part of the blood and tissue juices of a hy-
drogen ion concentration within certain nar-
row limits of variation has been established
through the work of J. S. Haldane and L. J.
Henderson. Recent investigations have not
only served to emphasize the importance that
the organism should maintain a certain acid-
base equilibrium for its physiological life, but
have also shown that when the mechanism
which regulates this equilibrium is interfered
with so that the hydrogen ion concentration
of the blood is increased and maintained for
an adequate time, the organism no longer
functionates normally, but becomes patholog-
ical in certain of its reactions.
It is not the object of this note to enter into
a discussion of the factors concerned in main-
taining a normal acid-base equilibrium, nor
to discuss those pathological conditions in
which a variation from the normal is fre-
quently observed. The object is to call atten-
tion to the influence of the age of the organ-
ism in controlling the mechanism by which
the acid-base equilibrium is kept within the
bounds of normality.
Some years ago, while conducting a series
of experiments in which uranium nitrate was
employed as the toxic agent to induce an
acute nephritis, the observation was made that
this substance was more toxic for old animals
than for young animals.t This variation in
1 MacNider, W. deB., ‘‘On the Difference in the
644
degree of toxicity was expressed by the older
animals becoming both albuminurie and gly-
cosuric at an earlier period following the use
of uranium than was the case with the young
animals. Furthermore, the quantitative out-
put in the urine of both albumin and glucose
was greater in the old animals than in the
young animals. When the kidneys of these
animals were studied histologically there was
found to exist more evidence of kidney injury
in the organs from old animals than in those
from young animals... In so far as the kidney
was concerned in the reaction, uranium was
more toxic in an old animal than in a young
animal.
In a later series of experiments? in which
the age of the animals was taken into account,
animals following an intoxication by uranium
gave evidence of developing an acid intoxica-
tion much earlier than did the younger ani-
mals. The experiments also demonstrated
that the acid intoxication in the older animals
was of a severer degree than in the young ani-
mals. The evidence for the development of an
acid intoxication in these animals of different
ages consisted in noting the time of appear-
ance and quantitative output in the urine of
acetone bodies, and in determining the rela-
tive degree of tolerance for an alkali by the
two groups of animals. The old animals
showed an earlier appearance in the urine of
acetone bodies, a greater quantitative output
of these bodies, and a greater tolerance for an
alkali than did the younger animals.
In these experiments it was furthermore
shown, that by the intravenous use of an alkali °
in a young animal the kidney could be success-
fully protected against the toxic effect of an
anesthetic while in the older animals the diffi-
culty of furnishing this protection increased
with the age of the animal.

[N. 8. Vou. XLVI. No. 1200
In a recent study? of the relative toxicity
of uranium nitrate in animals of different
ages, the observation has been made that the
old animals not only show a severer grade of
acid intoxication as indicated by the appear-
ance of acetone bodies in the urine than do
the younger animals, but these old animals
also show a more marked increase in the hy-
drogen ion concentration of the blood, which is
associated with a more rapid depletion of the
alkali reserve of the blood and a greater re-
duction in the tension of alveolar air carbon
dioxide. Associated with this change in the
acid-base equilibrium of the blood there de-
velops a kidney injury which is histologically
more marked in the old animals than in the
young animals.
In a final series of experiments‘ it has been
found possible to maintain in some measure
the functional capacity of the kidney and the
response of this organ to various diuretic sub-
stances by employing a solution of sodium
carbonate to restore the alkali reserve of the
blood and maintain an acid-base equilibrium
of the blood which approaches in degree the
reaction of normality. The ease with which
the acid-base equilibrium of the blood can be
restored and maintained in an animal intoxi-
eated by uranium, and the degree of protection
which is furnished the kidney is dependent
upon the animal’s age. The acid-base equi-
librium is more easily restored and can be
maintained for a longer time in a young ani-
mal than in an old animal. The protection of
the animal against the toxic effect of uranium
is more perfect in a young animal than in an
old animal.
From the experiments which have been
cited it would appear that there is a definite
association between the toxic effect of uranium
and its ability to induce an acid intoxication

and that the age of the animal very largely
determines the rapidity of development and
the severity of this intoxication.
When animals of different ages are intoxi-
cated by this metal the factor of the age of the
organism in the reaction is expressed by an
inability of the senile animal to maintain
with the same degree of perfection a normal
acid-base equilibrium as is the case with the
younger animal. Wm. vEB. MacNiprr

On the mechanism of the potassiwm chlorate-
manganese dioxide reaction: RAYMOND F. Bacon
and R. W. Miter. As the result of their experi-
mental investigation of the mechanism of the so-
called potassium chlorate-manganese dioxide reac-
tion, the authors conclude that: (1) Avoiding local
heating, potassium chlorate and manganese dioxide
begin to react at 255° C. The most vigorous reac-
tion oceurs at 310° C. (2) The potassium chlorate
oxidizes the manganese dioxide at the lower tem-
perature to form a higher unstable oxide, which
is decomposed later into manganese dioxide. It is
impossible to isolate this intermediate oxide on
account of the great velocity of the reaction. (3)
This initial oxidation generates heat, and this,
coupled with the heat applied, causes the reaction
to go, with a very rapid rise in temperature. This
high temperature causes certain secondary reac-
tions to oceur. (4) The first of these seconaary
reactions between the potassium chlorate and
manganese dioxide results in the formation of
manganous chlorate, which decomposes into man-
ganous chloride, chlorine and oxygen. The man-
ganous chloride is partially oxidized to manganese
dioxide and chlorine. Potassium oxide reacts
with manganese dioxide, in the presence of oxygen,
to form potassium manganate, which is changed
by some of the chlorine to potassium permanga-
nate, The excess of chlorine escapes. Of the po-
tassium chlorate used, only 0.503 per cent. enters
into tlrese changes. (5) An average of 5.428 per
cent. of manganese dioxide is used up in this re-
action. Almost all of this loss is accounted for
from the soluble manganese compounds produced
in the secondary reactions. (6) The manganese
dioxide serves as an interacting catalyst in this
reaction, hastening the speed of the change by
actually reacting with the potassium chlorate, to

form an intermediate oxide, which sets free the
manganese dioxide again before the conclusion of
the reaction.

ing metals under hydrostatic pressures from two

parative method—silver, bismuth, copper, zine,
brass, tin, cadmium, lead, gold, aluminium, tin-
bismuth alloy. The results are accurate to about
1 per cent. of their values. In the case of the
more compressible metals an estimation of the
falling off of the compressibilities at higher pres-
sures is obtained.

single gas has been begun with the formation of
ozone in the corona which is probably the simplest
form of electrical discharge occurring at atmos-
pherie pressure. Opposed to the ozonizing effect
there is a deozonizing effect with a resulting equi-

The qualitative separation and detection of gal-
lium: PuHintie EH. Brownine and Lyman E.
Porter. A study of the occurrence of the element
shows it to be most closely associated with Pb, Al,
Fe, Mn, Zn and In. Analytically it falls into the
Al group, its hydroxide being precipitated by
NH,OH in the presence of NH,Cl and being sol-
uble in an excess of NaOH. The chief analytical
problem is its separation from Al and two methods
are studied, both of which give satisfactory re-
sults. First, the method of de Bois Vaudran, pre-
cipitating Ge,(FeC,N.), by K,FeC,N, in the pres-
ence of strong HCl to about one third the volume
of the liquid. Second, saturating a solution with
HClga in the presence of ether, which throws out
the AlCl; and keeps the Ga in solution.
The qualitative detection of germanium and its
separation from arsenic; PHILIP E. BRowNING
and SEWELL E. Scorr. A study of the occurrence
of the element shows it to be most closely associ-
ated with Ag, Pb, Hg, Cd, As, Sn, Zn, Ti and Cb.
It falls in the analytical group with As and Sn
since its sulphide is soluble in (NH,).S. It is
separated from Sn by treating the sulphides with
(NH,).CO,, GeS, being soluble. From As it may
be separated by treating a solution of the sulpho
salts with ammonium acetate, acidifying with
acetic acid and passing H.S. As.S, is precipi-
tated and Ge remains in solution. The following
modification of Buchanan’s method was devised
for the separation and detection of Ge. The
germanium material was dissolved in strong hydro-
chlorie acid (5-10 em.*) in a test tube some
KMn0O, added, to keep arsenic if present in the
higher condition of oxidation and distilled into
another test tube kept cool in water. After dis-
tilling about one half volume the Ge is found in
the distillate by means of H.S.
Silver anion: H. C. P. WEBER. It is customary to
think of silver as a strictly monovalent element,
which forms in solution a positive ion. When a
solution of a silver salt is electrolyzed at high
current density a black deposit is formed at the
anode which has been variously described as silver
peroxide and as silver peroxynitrate, the formulas
ascribed varying but tending to indicate the pres-

ence of trivalent silver. It is now shown that in
this compound we have silver which in transference
experiments acts as an anion, probably trivalent,
a very unstable and intensely active oxidizing
agent. It is not derived from hydrogen peroxide
but rather of the permanganate type. The com-
pound is of great interest in connection with the
valence of silver in particular, and valence in
general.
The fixation of nitrogen with the silent electric
discharge: FARRINGTON DANIELS and OLIVER R.
Wutr. The oxidation of nitrogen by the silent or
cold electric discharge has been proved. No
energy is lost as heat, and under the proper con-
ditions nitrogen pentoxide instead of nitrogen
peroxide is formed. This should simplify the ab-
sorption towers. Pressure favors this reaction
but not the reaction which gives nitrie oxide.
Practical applications have failed because the re-
action is too slow. A search for a catalyzer was
unsuccessful. Experiments with various types of
discharge chambers look hopeful.
The displacement of nitric by carbonic acid in
silver nitrate solutions and the relation of this re-
action to the inclusion error in the silver voltam-
eter: A. 8S. McDanien and H. D. Hinexine. It
has been shown that carbon dioxide reacts slowly
with silver nitrate in aqueous solution forming a
carbonate of silver and liberating free nitric acid.
Crystals of the carbonate have been isolated and
identified. The nitric acid liberated has been
estimated by titration with iod-eosin and its
amount compared with the silver contained in the
crystals of silver carbonate. The reaction is be-
lieved to be as follows:
Ag NO, + H,CO, = Ag HCO, + HNO.
About one one-hundredth of one per cent. of the
silver nitrate is converted to the carbonate. In
the silver voltameter a clear solution of silver ni-
trate which has been saturated with CO, gives a
deposit about 0.4 per cent. too heavy. This effect
was first shown by Rosa Vinal and McDaniel, but
it was thought by them that the amount of CO,
normally present in air has no appreciable effect
upon the mass of deposit. In the present investi-
gation a few direct measurements have been made
of the effects produced by une to ten times the
normal amounts of CO, present in the air and
while the results are incomplete they indicate that
the effect of the normal amount of CO, in the air
is not negligible and indeed may be larger than
the inclusion error in normal deposits. :

An Important Contribution to the Literature of Science
A Short History of Science
BY
W. T. SEDGWICK, H. W. TYLER,
Professor of Biology Professor of Mathematics
at the Massachusetts Institute of Technology
The history of science is as engrossing as the history of
Greece and Rome and gives as sure an indication of the
growth of civilization as does the history of philosophy, art,
literature, or music.
The literature of science has always been more or less
technical both in the subject matter and the form of its presen-
tation, and Professors Sedgwick and Tyler have rendered a
great service to the lay reader as well as to the student in
writing a history of the development of science from its re-
motest period, through the romance of Mediaeval astrology
and alchemy to the tremendous achievements of the last
centuries.
“A Short History of Science” is one of the first books
of its kindin English and is the result of the authors’ many
years of joint teaching of the subject. It is a book which
will prove of the greatest value to Universities, Colleges,
Scientific and Technical schools, and is especially adapted
to general reading and reference.

THE SIONS INDUCTOMETER
In the Brooks’ Inductometer is offered
a compact form of variable inductance,
with a self inductance range of 5 to 50 milli-
henrys, possessing the following advan-
tages:
1. A fair degree of astaticism, which
tends to eliminate errors due to stray
field effects.
2. It is less expensive and at the
same time fully as accurate as the Ayrton-
Perry instrument.
3. It occupies less space than the
Aryton-Perry form.
The instrument has a very nearly uniform scale, obtained by properly proportioning the coils.
It may be used as a mutual inductance.
It has a good ratio of maximum to minimum inductance (about 9 to 1) and also has as high
a time constant as is consistent with good design and moderate size.
The instrument is fully described in Bulletin No. 152, a copy of which will be sent upon request.

that the first and second years are largely occupied by the fundamental medicalsubjects. The third and fourth years are
largely devoted to the practical branches, prominence being given to clinical instruction, and the classes sub-divided into
small groups so that the individual students are brought into particularly close and personal relations with the instructors
and with the patients at the bedside and in the operating room. After graduation further hospital work is un-
dertaken by the members of the class; and more than 90 per cent. attain by competitive examination or by appoint-
ment positions asinternes in hospitals in this city or elsewhere. The Pennsylvania Bureau of Medical Education and
Licensure requires of applicants for license a year spent in an approved hospital.
