THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE.
EXECUTIVE PROCEEDINGS: REPORT OF THE GENERAL SECRETARY.
THE first meeting of the American Association for the Advancement of Science was
held in the City of Philadelphia, September 20th, 1848. There were then 461 members
of the Association, but we have no record of the number in attendance. The second
Philadelphia meeting was held September 3, 1884. The Association then numbered 1,981
members and the attendance was 1,261, including 303 members of the British Association
for the Advancement of Science and nine other foreign guests. The third Philadelphia
meeting was held December 27 to 31, 1904. The total membership was nearly 4,000
and the registered attendance numbered 588 members and 104 members of affiliated
societies, making a total registered attendance of 692 members. From 200 to 400 did not
register, so that we may safely conclude that the total attendance was at least 890, and
perhaps very much larger.* The present meeting is, therefore, the third largest in point
* We estimate the number of scientific men in attendance to have been in the neighborhood of 1,200.
240 members of the American Chemical Society were registered, but only 75 for the Chemical Section of the
Association. There were nearly 100 members of the American Psychological and Philosophical Associations
in attendance, very few of whom registered. The conditions were probably similar in other sciences.—ED.

of numbers since the year 1884. While
numbers are not an index of the value of
a meeting, they do show the amount of
interest taken in its proceedings, and from
that standpoint we may conclude that the
third Philadelphia meeting was a success.
It was also a suecess from the standpoint
of number of papers read‘and the general
interest in the papers, as well as in all of
the proceedings of the association.
Tabulating the members according to the
sections for which they registered, we find
the following numbers:

giving a total of 581 who signified their
preference as to sections.
These figures show that where a national
scientific society met in conjunction with
the association, the corresponding section
was large and where a national scientific
society did not meet, the attendance was
very small. This would seem to indicate
that members of the association prefer to
attend a meeting of the national society
rather than the meetings of the association
unless the two meet together.
The University of Pennsylvania placed
its halls and laboratories freely at the dis-
posal of the association and each day fur-
nished a lunch to the members. The asso-
ciation has never received more careful at-
tention than it received at this meeting.
A vote of thanks was extended to the uni-
versity, the details of which will be found
later on in the report.
In former years a daily program has
been published, showing the papers to be
[N.S. Vor. XXI. No. 523.
read that day and giving a list of the mem-
bers in attendance. This has always been
a severe drain upon the resources of the
association and it was decided this year
to use but one program, which was dis-
tributed to members on the first day papers
were read. This single program seemed
to answer its purpose as well as the daily
programs have in the past, except that
many members missed the lists of those in
attendance. If some method can be de-
vised by which members may know who are
present, there can be no objection to the
single program.
Since the last meeting of the association
377 members have been elected; although
this is not as large as the number elected
in previous years, yet it shows a steady
growth and a growing interest on the part
of the public in the work of the association.
There has always been great difficulty in
getting reports of the association and its
work published in the daily papers, except
those in the city where the meeting is held.
This year the Committee on Policy of the
Association instructed the permanent seere-
tary to appoint a press secretary. The
permanent secretary appointed Mr. Theo-
dore Waters. Reports of the meetings
were prepared each day and sent to most
of the prominent newspapers of the coun-
try. It was impossible to make the re-
ports as full as desired, as some of the
members of the association who read papers
did not give their abstracts to the press
secretary, although they were requested to
do so. If the readers of papers will take
pains to see that their abstracts are in the
hands of the press secretary, entirely satis-
factory reports can be sent out in future.
It is greatly to be desired that the press of
the country give some attention to the
meetings of our greatest scientific society.
The two questions of general interest
were the time of meetings of the associa-
tion and our relation to the affiliated so-
JANUARY 6, 1905.]
cieties. These questions have been actively
discussed before, but they do not seem to
be definitely settled in the minds of many.
The sections which have been in the habit
of giving excursions and those who study
objects out of doors, prefer a summer meet-
ing, but it seems that a large majority of
the association is in favor of the winter
meetings, as the general committee unani-
mously decided to hold the next meeting
during the winter. The committee on
policy reported that it had considered this
matter and would recommend that this
general committee request the next general
committee to hold a summer meeting in
Ithaca during the summer of 1906. The
suecess of this meeting will undoubtedly
have a great deal to do with settling the
question of summer meetings.
There seems to be no objection on the part
of the association to holding two meetings
each year, one during the winter and one
during the summer. The expense involved
would be considerable, but the association
can bear it and perhaps the best solution of
the problem will be two meetings. This is
a question which the future must decide.
AFFILIATED SOCIETIES.
The following Affiliated Societies held
sessions in conjunction with the associa-
tion:
American Alpine Club.
The American Anthropological Association.
The American Chemical Society.
The American Folk-Lore Society.
The American Geographers’ Association.
The American Mycological Society.
The American Philosophical Association.
The American Physical Society.
The American Psychological Association.
The American Physiological Society.
The American Society of Naturalists.
American Society of Vertebrate Paleontologists.
Association of American Anatomists.
The Association of Economie Entomologists.
The Astronomical and Astrophysical Society of
America.
SCIENCE.
The Botanical Club of the Association.
The Botanical Society of America.
The Society for Plant Morphology and Phys-
iology.
The Society for the Promotion of Agricultural
Science.
Sullivant Moss Chapter.
The Wild Flower Preservation Society of
America.
The Entomological Club of the Association.
Eastern Branch of American Society of Zoolo-
ogists.
The Fern Chapter.
The Geological Society of America.
The Sigma XI Honorary Scientific Society.
The Society of American Bacteriologists.
The Society for Horticultural Science.
The Southern Society for Philosophy and Psy-
chology.
The Pelee Club.
The association is still pursuing the
policy of encouraging the great national
societies to meet at the same time and
place with it. The association secures
rooms, provides accommodations, makes ar-
rangements with hotels and railways and in
all points takes charge of general arrange-
ments without expense and without trouble
to the affiliated societies.
Nearly, if not all, of the societies meet in
perfect harmony with the respective sec-
tions. In almost every case the sections
have charge of the general session in one
half of the day and the affiliated societies
have charge of the meetings during the
other half of the day. Thus there is no
friction and papers are presented before
both bodies, while there is the additional
advantage of a larger attendance at both
the section and the society. It is hoped
that this arrangement will appeal still
more to the national societies until all
of them enter into this arrangement with
the association.
The attendance of the members of the
societies this year indicates that they are
willing to cordially cooperate with the as-
sociation and turn out in large numbers to
attend these joint meetings. There is

nothing in the arrangement which prevents
an affiliated society holding a _ separate
meeting at any other time of the year if it
chooses.
The first session of the fifty-fourth meet-
ing of the American Association for the
Advancement of Science was called to order
in College Hall Chapel, University of Penn-
sylvania, Philadelphia, Pa., at 10 a.m.,
Wednesday, December 28, 1904, by the
retiring president, Dr. Carroll D. Wright.
Dr. Wright introduced the president-elect,
Dr. William G. Farlow, who made a brief
address. "Provost Harrison, of the Univer-
sity of Pennsylvania followed with an ad-
dress of welcome.
President Farlow thanked Provost Har-
rison for his words of welcome and then
asked the general secretary to make the
announcements from the council.
Mr. Howe (general secretary) : The Council has
voted to extend the privileges of associate mem-
bership for this meeting to members of the local
committee, residents of Philadelphia and vicinity
and to members of the affiliated societies.
The following committees have been appointed
to serve during this meeting:
Committee on New Members: The permanent
secretary and the secretary of the Council.
Committee on Fellows: The general secretary
and the vice-presidents of the sections, Mr. Howe,
chairman.
Committee on Grants: The treasurer and the
vice-presidents of the sections, Mr. R. 8. Wood-
ward, chairman.
It has been decided to hold sessions of the
Council at nine o’clock in the morning, but there
will be no other general session until Saturday
morning at ten o’clock.
Dr. Calvert, secretary of the local com-
mittee, made some announcements in be-
half of that committee in regard to the
arrangements which had been made for the
comfort and convenience of the association.
After the adjournment of the general
session the several sections were organized
in their respective rooms.
In accordance with a suggestion from
the committee on the policy of the asso-
(N.S. Vou. XXL. No. 523.
ciation, the vice-presidential addresses were
scattered throughout the week, instead of
being given on the same date.
It was thought best to have in addition
to a vice-presidential address, one or more
papers of general interest, which would fol-
low the address, thus taking up the greater
part of that session.
The general program of the week was as
follows:

the council and reported to the general
session, was adopted:
Amend Article 34 by the omission of the
words ‘‘On the election of any member as
fellow, an additional fee of $2 shall be
paid.’’
The proposed amendment of article 4,
line 2, to read ‘‘The members of at least
one year’s standing, who are professionally
engaged in science and have, by their
labors, aided in advancing science’’ was
unfavorably reported upon by the commit-
tee on policy.
POLICY OF THE ASSOCIATION.
The council appointed Mr. R. S. Wood-
ward permanent chairman of the commit-
tee on policy of the association.
The council voted that the committee on
policy of the association be requested to
exercise a general executive control of the
preliminary arrangements for meetings and
of the publications, subject to the control
of the council.
The committee on policy of the associa-
tion reported the following resolutions
which were adopted:
‘““That the permanent secretary be au-
thorized to offer sets of the back volumes of
the Proceedings to libraries, which shall be
approved by the committee of the associa-
tion appointed by the president.’’
‘“That the publishers of ScteNcE be re-
quested to announce prominently that eut
copies will be sent to members who request
it:??
‘“That the committee recommends as
members, and if they become members,
nominates as fellows, members of the na-
tional scientifie societies not now members
of the association in eases in which the
national scientific society has a qualifica-
tion for membership equal to that of the
qualification of the association for fellow-
ship. The following societies are accepted
as having such qualifications :

LINES OF PROGRESS IN ENGINEERING.*

of difficulties, redoubts of prejudices, bat-
teries of tradition and in citadels of igno-
rance. Like the Japanese, the division com-
manders, looking well to their supplies of
ammuniticn (7. é@., correct theories) and
their daily rations (7. e., materials of con-
struction and shop practise), push forward
now at one point and now at another, cap-
turing hill after hill, now on the right, now
on the left, and now in the center. The
army of science never retreats; it forever
forees back the frontiers of darkness, and
solves problem after problem from the end-
less list of secrets with which the store-
houses of nature are filled.
It is a glorious thing to belong to this
engineering army, to rejoice in its triumphs
and to share in its rewards. Its success is
not accidental ; its triumphs are not matters
of chance. Iingineering blood always tells.
Just as we train our best soldiers and sail-
ors at West Point and at Annapolis; and
as our appliances at military and naval
schools keep pace with the arts of war on
land and sea; so our schools of engineering,
if they are up-to-date institutions, keep
pace in the theories they teach and in the
laboratories they equip with the best en-

send forward may be just what is wanted,
we must have information as to the prog-

In short, our schools of engineering must
know the lines of engineering progress.

two of us would agree upon their relative
importance ; one’s environment has so much
to do with what lies just beyond his hori-
zon; so I doubt not you will supplement
my statement with most interesting and
valuable suggestions.
THE UTILIZATION OF WASTE ENERGY.
While much has been done and much
more is doing at waterfalls and river
rapids, large and small, the work of saving
the energy which now runs to waste has
but. just begun. When the great water-
falls are utilized the rapids will rémain.
We are lost in wonder when we calculate
the possibilities. Measure the volumes
which rush over the ‘Sault St. Marie,’ as
the waters of Lake Superior drop to the
level of Lake Huron; and then again put
your measuring rods into the vastly greater
volumes which plunge and rush from Lake
Erie to Lake Ontario; and still again
through the rapids of the St. Lawrence to
the sea level. At every vantage ground,
the work of utilization has begun and na
man now living will see that work stop.
Turn next to smaller streams and mountain
torrents—what fields open up to the hy-
draulie and electric engineers! Mountain
reservoirs will serve the triple purpose of
preventing destructive floods, of saving the
energy for useful work and of aiding irri-
gation. At every count the doors open
wide for the best of engineering enterprise
and the best of engineers, hydraulic, me-
chanie, electric, irrigation, and the echo of
each department must be heard in the en-
eineering lecture-room and laboratory. The
electric transformer has made the transmis-
sion of energy possible from mountain
slopes to far cities, and has unlocked be-
wildering amounts cf energy at thousands
of points deemed hitherto inaccessible. No
one ean see far into the future, but we ail
easily see the dawn of a new era of energy
saving. The streets of this city may y-t

be lighted by the energy which now runs to
waste at Niagara. In St. Louis we look to
the slopes and canyons of the Rockies for
our supply of sweet, wholesome water—we
may yet look to the same regions for the
energy to drive our cars and run our mills.
COMBUSTION ENGINES.
The clumsy steam-engine, with its waste-
ful furnace, its huge boiler and chimney,
is doomed. It has done great work in
producing available energy and in wasting
still more. It has played a most important
part in modern civilization, and it deserves
well at our hands, but nothing ean stay
the deeree of progress. Sentence will soon
be pronounced, but the day of execution
has not been set. I never expect to see
the day when steam power plants will cease
to exist, but my children will see such a
day.
Think for a moment of the present com-
plicated, indirect method of procedure for
converting the energy stored in coal into
mechanical energy in a moving piston or
a revolving shaft. Coal and air are fed
into a furnace where combustion converts
them into great volumes of a mixture of
hot gases. The greater part of the heat
and all the volume of these gases escape
through the chimney; a small part of the
heat only is drawn off by the steel shell
and tubes of a boiler and transmitted to a
body of water, which is thereby trans-
formed into steam. The steady generation
of steam against high pressure, added to
its expansion as the pressure is reduced,
enables it, when conducted to a cylinder, to
drive a piston or revolve a shaft, thereby
producing mechanicai power. The clumsi-
ness of the operation is equalled only by its
wastefulness, which varies from 88 per
cent. to 95 per cent.
The problem to-day is: What 1s the most
direct and most economical road from coal
to moving machinery? Engineers are at-

tacking this problem on all sides, and at-
tacking it suecessfully—gas-engines, and
combustion-engines of various sorts bear
witness. The future prime-mover will burn
(not explode) its fuel in the working
eylinder, and the piston will be driven,
first by the products of combustion as their
volume inereases, and secondly by their ex-
pansion against a diminishing resistance.
I predict great things of the Diesel motor.
Originally it was designed to burn
powdered coal mixed with hot compressed
air; but erude petroleum was found to be
preferable. So long as oi! flows abund-
antly from wells, oil will generally be used,
but powdered fuel, native or prepared, will
doubtiess prevail ultimately. The economy
and directness of the combustion motor
can not be excelled, and when a few years
of study and experiment have been applied
to the work of simplifying the mechanism
(it was a century from James Watt to a
triple-expansion Corliss), we may expect
it to come into general use for all great
central power stations.
The vitality of the steam-engine is due
to-day to the mechanical perfection of its
design. Its simplicity is marvelous. It
is started and stopped with the greatest
ease and it almost takes care of itself. The
invention of the steam turbine has prob-
ably given to the furnace and steam-boiler
another lease of life. The wonderful
adaptability of the turbine for electric gen-
erators is something which was not an-
ticipated.
Will not some one design and construct
a combustion engine which shall consume
continuously oil and compressed air, thus
maintaining a high pressure in a gas chest
and driving a turbine with the products of
the combustion used expansively as is now
done with steam? The proposition is an
attractive one, both for the lecture room
and for the engineering laboratory. It is
sufficient now to eall attention to its pos-
10 : SCIENCE.
sibility, and to indicate a point for study
and progress.
It will not be amiss for me to quote the
figures given me by the engineer in charge
of the Diesel engines which drove. the
generators for power and light in the
‘Tyrolean Alps’ at the late world’s fair in
St. Louis.
These engines, three in number, of 225
horse power each, were the cbserved of
many observing engineers during the seven
months of the fair. The assistant engineer
in charge kept daily records of the work
done, and fuel used, and kindly gave me
a sample of his reports. The details are
extremely interesting. The work was
measured at the switchboard, no allowance
being made for loss of energy in the engine,
air pump and generator. The total work
of the three engines between noon and
midnight was 2,768.5 K.W.H. This is
equivalent to 3,711 H.P.H.
Total fuel used (Indiana oil), 266 gals.
Fuel per 100 K.W. hours, 9.58 gals.
Fuel cost in car-tank lots, 3c. per gal.
Cost per 100 K.W.H., $0.287.
Cost of the day’s fuel, $7.98 or 2.15 mills per
ishieniale
Thus one cent paid for the fuel for one-
horse power for four hours, forty minutes.
The three engines worked under about
two thirds of a full load and used three
gallons of lubricating oil during the day.
The above figures seem to me little less
than remarkable.
While still wasteful, as nature measures
energy, these engines are several times as
efficient as the better styles of ordinary
steam-engines. Doubtless they lack sim-
pheity and the certainty of action which
comes from experience and close study;
but I can not help feeling that the road
to the future ‘prime mover’ runs hard by
the construction shops of an internal-com-
engine. Let studerts and pro-
fessors take warning.

ARTIFICIAL CENTERS OF POWER.
One of the most important openings for
future engineering enterprises is the estab-
lishment of large power centers, not only
where water power is available, but where
iuel is abundant as well.
Take, for example, the vast coal mines
in the vicinity of the city of Philadelphia
and those in the vicinity of St. Louis. In
each case the puwer for industrial estab-
lishments and all kinds of moving ma-
chinery, large and small, in use in the
city, including the street cars and the
rolling stock on all roads, can well be
furnished by electrical currents from large
gcnerating establishments near the mines.
Add to the above the establishment of gas
works sufficiently large to furnish all the
gas needed for illumination, for gas-en-
gines, for heating and cooking purposes in
a great city. In the ease of St. Louis those
gas works should be near the extensive
coal mines of Belleville and other coal-
producing regions only a few miles from
the eity.
The effect of these two great steps for-
ward upon the physical and sociological
characteristics of a city can hardly be over-
estimated. The ultimate economy and con-
venience of such installations are enough to
justify them. We have yet to learn how
cheaply fuel gas and electric currents can
be furnished to large concentrated groups
of consumers. But omitting all questions
of mere financial economy, what a saving in
health, beauty and enjoyment! The Lon-
don fogs which we hear so much about are
produced largely by London smoke, and the
prevention of smoke will to a very great
extent be the prevention of the fog. _I look
forward to the day when, instead of a small
voleano of smoke from a brick crater above
every house, St. Louis will have all its
heating and cooking done by gas, and all
power will be furnished by electric cur-
rents, or by gas and combustion-engines,

both gas and electricity coming from the
gas works and power plants at the mouths
of the coal mines in Illinois. What an era
of cleanliness and comfort this presages!
This era of cleanliness will be brought
about by the engineers. Hence engineer-
ing education must see to it that engineer-
ing students are prepared for their high
mission. The proposed ‘Million Club’ of
St. Louis bears no comparison with a pos-
sible ‘Clear Sky Club.’ The former pro-
poses to seduce 250,000 non-resident smoke-
makers imto joining the 750,000 smoke-
makers already resident in St. Louis, there-
by making smoke enough to shut out the
sun entirely (they almost did it during a
whole week last November). The ‘Clear-
Sky Club,’ on the other hand, will propose
to eliminate all smokers by sending coal-
burning power plants to the mines, thereby
leaving the city so clean and beautiful that
250,000 lovers of pure air, clear skies and
godliness will seek homes among us of their
own accord. The elimination of smoke,
soot and ashes will make St. Louis abso-
lutely bright and clean, and similar im-
provements here would go far towards pro-
ducing the same beneficial results in the
city of Philadelphia. Already our cities
have, or are making arrangements for, an
abundant supply of pure water. This has
been and still is a great branch of engineer-
ing, and it deserves an important place in
our schools of engineering. We must next
provide pure air and a clear sky.
These steps forward involve no very
ereat addition to our engineering knowl-
edge, but they give opportunity for engi-
neering enterprises, and they show most
clearly how essential cooperation is in such
work. Large power plants and extensive
gas works require much private capital,
unless we fly to the extreme of public
ownership. The economic construction of
large power plants and gas plants; the lay-
ing of pipe lines and an unprecedented

After considering the subject of multiple
contingency and its relation to multiple nor-
mal correlation the author proceeds to’ give
some illustrative examples showing something
of the sort of problems to which the method
may be applied, and also how it is to be used
in practise. The examples include (a) the
correlation between father and son in respect
to stature, (b) color inheritance in grey-
hounds, (¢c) fraternal resemblance in hair
color in man, and (d) the correlation between
father and son in respect to occupation or
profession.
The net results brought out by the analysis
and confirmed by the numerical illustrations
may best be stated in the author’s own words:
[N.S. vou. XXI. No. 523.
“With normal frequency distributions both
contingency coefficients pass with sufficiently
fine grouping into the well-known correlation
coefficient. Since, however, the contingency
is independent of the order of grouping, we
conclude that, when we are dealing with al-
ternative and exclusive sub-attributes, we
need not insist on the importance of any par-
ticular order or scale for the arrangement of
the subgroups. This conception can be ex-
tended from normal correlation to any dis-
tribution with linear regression; small changes
(%. e., such that the sum of their squares may
be neglected as compared with the squares of
mean or standard deviation) may be made in
the order of grouping without affecting the
correlation coefficient.” These results “are
not so fruitful for practical working as might
at first sight appear, for they depend in prac-
tise on the legitimacy of replacing finite in-
tegrals by sums over a series of varying areas,
where no quadrature formula is available. If
we, to meet the difficulty, make a very great
number of small classes, the calculation, es-
pecially of the mean square contingency, be-
comes excessively laborious. Further, since
in observation individuals go by units, casual
individuals, which may fairly represent the
frequency of a considerable area, will be
found on some one or other isolated small area,
and thus increase out of all proportion the
contingency. The like difficulty oceurs when
we deal with outlying individuals in the case
of frequency curves, only it is immensely ex-
aggerated in the case of frequency surfaces.
It is thus not desirable in actual practise to
take too many or too fine subgroupings. It is
found, under these conditions, that the cor-
relation coefficient as determined by the prod-
uct moment or fourfold division methods is
approximated to more closely in the ease of
the contingency coefficient found from mean
square contingency than in the case of that
found from mean contingency. Probably 16
to 25 contingency subgroups will give fairly
good results in the case of mean square con-
tingency, but for each particular type of in-
vestigation it appears desirable to check the
number of groups proper for the purpose by
comparing with the results of test fourfold
JANUARY 6, 1.95.)
division correlations. Under such conditions
it appears likely that very steady and consist-
ent results will be obtained from mean square
contingency.”
In the caleulation of contingency coefficients
the present writer has found that the follow-
ing procedure saves much time and _ labor.
The value of the independent probability r,,,
for each compartment of the table is obtained
by the use of a Thacher calculating instru-
ment (Keuffel and Esser). With this instru-
ment one can read directly to four or five
figures the values of any expression which can
be put into the form ax/b, where a and b are
constants and x is a variable. Since y,, for
any compartment equals (n,-m,,)/N for that
compartment, it is evident that by taking
either n, or m, as the constant, it will only
be necessary to make as many settings of the
instrument as there are rows or columns in
the table. Having obtained the y,, quanti-
ties, the sub-contingencies (n,,,— y,,,) may be
written down directly, squared from Barlow’s
tables, and divided by y,,, with an arithmom-
eter or with Zimmermann’s or Crelle’s multi-
plication tables. The remainder of the caleu-
lations necessary to obtain the mean square
contingency and the whole of the calculations
for the mean contingency, and their respective
coefficients are, of course, easily performed.
Proceeding in this way, the calculation of con-
tingency coefficients, even though several ex-
perimental groupings are made, has been
found to take but comparatively little time.
The noteworthy features of this method of
contingency are found in that it, in the first
place, broadens and illumines the whole theory
of correlation, and in the second place, brings
within the range of biometrical investigation
a large series of problems to which it has
hitherto been impossible to apply exact meth-
ods. One ean but feel that this memoir, like
so many of the others which have preceded it
in the series, marks a definite and funda-
mental step in advance in the steady progress
of the science of biometry.

‘GLUCINUM’ oR ‘ BERYLLIUM.’
SoME years ago the question of choice be-
tween the two names ‘glucinum’ and ‘ beryl-
SCIENCE. 30
lium’ was gone into quite carefully by Pro-
fessor F. W. Clarke and also by the committee
appointed by the American Association on
the Spelling and Pronunciation of Chemical
Terms, and the conclusion was arrived at that
the name ‘glucinum’ should be used on the
ground of priority. In Science for Decem-
ber 9 Dr. Charles Lathrop Parsons has stated
his grounds for preferring the name ‘ beryl-
lium.’ Dr. Parsons is, thanks to his biblio-
graphical work on the element in question,
thoroughly informed in its literature, but the
arguments adduced by him would seem to lead
to a conclusion diametrically opposed to that
which he has drawn.
It was obviously the privilege of Vauquelin,
the discoverer of the element, or rather its
oxid, to name it. This he never did, but con-
tented himself by speaking of it at first as ‘la
terre du Béril,’ that is, the earth in beryl. At
the close of Vauquelin’s first paper the editors
of the Annales added a note signed ‘ Redac-
teur’ in which they propose the name ‘ glu-
It was of course well known that Guy-
ton and Fourcroy were the editors. Vauque-
lin’s second paper in the Annales was evi-
dently prepared at the same time as the first,
or at least before the second was in print.
In his third paper, some weeks later, as Dr.
Parsons admits, Vauquelin actually adopted
the term ‘ glucine,’ prefacing its use with ‘on
a donné le nom de glucine.’ The paper in the
Journal des Mines was apparently prepared
at the same time as the first two papers in the
Annales and before the appearance of the sug-
gestion of Guyton and Fourcroy, but at its
close occurs the note which Dr. Parsons has
quoted. In this he states that Guyton and
Foureroy have advised him to call the new
earth ‘glucine’ and while he evidently does
not think the name the best that could have
been chosen, he clearly acquiesces in the sug-
gestion of the two great authorities and says
“Cette denomination sera assez significante
pour aide le mémoire.’- Finally, as seen above,
in his third paper, he adopts the name. As
far as priority goes, the argument in favor of
‘beryllium’ would seem to be that probably
Vauquelin would have given the earth some
other name had he ventured to dissent from
cine.’
36 SCIENCE.
Guyton’s authority, and it is probable that he
would have liked to name it ‘ beryllia.’ All of
which may be quite true, but actually he did
not do it.
As regards the German use of ‘ Berylerde’
it was merely at first the natural translation
of Vauquelin’s expression ‘la terre du Béril,’
which, as we have seen, he used in no denom-
inative sense. If the generally accepted rules
of priority have any weight ‘ glucinum’ is the
only term to be used for the element.
As regards usage, the case is hardly quite
as bad as Dr. Parsons seems to think, since
the index to the Journal of the Chemical So-
ciety (London) for 1903 gives ‘ Beryllium, see
glucinum.’ With French, English and Amer-
icans using ‘glucinum,’ we can afford to let
the German journals cling to ‘beryllium’ a
little while longer.
Incidentally, what shall we do when the
Germans insist on kalzium, kolumbium, karo-
linum, zerium and zesium, or will it be
keesium ? Jas. Lewis Howe.

BOTANICAL NOTES.
THE STUDY OF FIBERS.
Tre book (‘ The Textile Fibers, their Phys-
ical, Microscopical and Chemical Properties ’)
prepared by Dr. J. M. Mathews, and recently
published by John Wiley, should make the
study of textile fibers somewhat easier by stu-
dents and practical operators. It covers
nearly three hundred pages of neatly printed
text, illustrated by sixty-nine cuts, in which
the author has presented the whole matter
in a most helpful way. There is first a use-
ful classification of fibers, followed by deserip-
tions and discussions of those which enter
into fabrics. Some of these fibers are, of
course, of animal origin, as wool, hair and silk,
and to these are given about ninety pages.
The remainder of the book is devoted almost
wholly to plant fibers, and here the treatment
is especially clear and helpful. The origin,
varieties, physical and chemical properties of
cotton, and mercerized cotton, are discussed in
as many chapters. Linen is given another
chapter, while jute, ramie, hemp and several
[N.S. Vou. XXI. No. 523.
other fibers of minor importance are disposed
of in another chapter. An interesting chapter
for the general reader is the one on artificial
silks, the processes for the production of which
“have been attended with a considerable degree
of success.’ It is said that artificial silk ‘ has
become a commercial article, and is used in
considerable quantity by the textile trade.’
Of these artificial silks there are four general
kinds, viz:
1. Pyrozylin silks, made from a solution of
gun cotton in a mixture of alcohol and ether.
2. Fibers made from a solution of cellulose
in ammoniacal copper oxide or chloride of
zine.
3. Viscose silk, made from a solution of
cellulose thiocarbonate.
4. Gelatin silk, made from filaments of
gelatin rendered insoluble by treatment with
formaldehyde.
Most of the artificial silk is of the first
variety, the manufacture of which is carried
on in England, Germany, France and Switzer-
land. “The fibers are formed by forcing the
ether-aleohol solution of pyroxylin through
glass capillary tubes, and winding them on
frames. As the solution is very viscous it re-
quires a pressure of forty-five atmospheres to
discharge it through the capillary openings.”
A STUDY OF COMPARATIVE EMBRYOLOGY.
THE comparative embryology of the Cucuwr-
bitaceae (Gourd Family) has been studied by
Dr. J. E. Kirkwood, the results of which ap-
pear in the Bulletin of the New York Botan-
ical Garden (No. 11, 1904). After an
instructive historical introduction, the organ-
ogeny of representatives of the five tribes
(Fevilleae, Melothrieae, Cucurbiteae, Sicyo-
ideae, and Cyclanthereae) is summarily de-
scribed, and this is followed by a quite
particular examination of the embryo-sae in
sixteen genera distributed among the five
trikes. Twelve fine plates of 166 figures add
much to the value of this portion of the paper.
In a closing discussion the author finally con-
cludes that ‘in most points the differences
between the Cucurbilaceae, and other sym-
petalous families are more striking than the
similarities.’ The paper closes with a bibli-

ography including 89 titles. It constitutes
a valuable addition to our knowledge of the
embryology of a family whose place in the
system of plants is still in doubt.
A HELPFUL BULLETIN.
Tue office of experiment stations of the
United States Department of Agriculture has
issued a bulletin (No. 2) consisting of an
outline of a lecture on ‘ Potato Diseases and
their Treatment,’ for the use of farmers’ insti-
tute lecturers. It was prepared by F. C.
Stewart and H. J. Eustace, of the New York
Experiment Station. It contains summaries
of our knowledge of the most important dis-
eases which affect the potato in the United
States. The descriptions are given in non-
technical language, and ought to convince
every botanist of the possibility of treating
quite difficult subjects in plain English. Fol-
lowing the description of diseases, is an ad-
mirable chapter on spraying and other pre-
ventive measures.

ACADEMIC IDEALS.*
Tue beginning of an academic year calls
up at once the lighter thoughts of pleasing
associations and the graver thoughts of in-
spiring obligations. Here on the table-
land of intellectual life youth and age
meet to labor for a season in the fields of
knowledge and discovery. The confident
optimism of youth seeks to be chastened
by the gentle admonition of experience.
Youth imparts its buoyancy to age, age im-
parts its wisdom to youth, and both are
kindled by the glow of elevating aspira-
tions. It is a time, therefore, for a blend-
ing of our lighter and our graver reflec-
tions.
Being delegated for the moment to speak
to and for this academic body, it has seemed
that some considerations on academic ideals
might serve to awaken thought and to
arouse zeal appropriate to the occasion. °
In the abstract, however, this would appear
to be a delicate and a difficult subject;
delicate because of diversity of sentiment,
and difficult because of diversity of judg-
ment, amongst those best qualified to
speak, as to what academic ideals are, or as
to what they should be. Hence it may
seem fitting at the outset to suggest appli-
cation to the views here set forth of the
Soeratic caution that they ean hardly be
exactly as represented, if not the more
sweeping caution of Mareus Aurelius—
‘Remember that all is opinion.’ But the
delicacy and the difficulty of the subject

are probably more apparent than real to
us; for this is a university assembly, and
it is one of the highest functions of a uni-
versity to examine the various aspects of
debatable questions without suppression of
eandor and without loss of humor.
The typical American university of our
time is a complex organization which has
erown up rapidly from the typical Amer-
ican college of a half century ago. It has
its undergraduate, its professional and its
post-graduate schools, as we see them in
Columbia University to-day. It has a
heterogeneous aggregate of students ani-
mated: by a great variety of aims and pur-
poses. Its curricula embrace courses of
study and research quite unknown to the
educated public of thirty or forty years
ago; and its degrees recognize professions
quite unheard of before the middle of the
nineteenth century. Moreover, the modern
American university has broken to a large
extent with custom and tradition. It is
an institution characterized by intellectual
agitation, by adjustment and readjustment,
by construction and reconstruction, the end
of which is not yet in sight. This complex
organization is the resultant of the more
or less conflicting educational activities of
It is a resultant due in part
to world-wide influences; it expresses a
generalized academic ideal.
Whatever may be our inherited prej-
udices or our calmer judgments, the attain-
ment of this ideal must be regarded as a
remarkable achievement. Here, for ex-
ample, in this institution, we find all kinds
of subjects of study, from the most ancient
to the most modern, from the most prac-
tical to the most theoretical, from the most
empirical to the most scientific, from the
most materialistic to the most spiritualistie,
all on a plane of intellectual equality and
all equally available to those fitted to pur-
sue them. Little surprise is manifested at
the close juxtaposition of a professor of
our times.
[N.S. Vor. XXI. No. 524.
metallurgy and a professor of metaphysics,
and it has actually been demonstrated that
professors of poetry and professors of
physics can dwell in peaceful activity un-
der the same roof. Here too the ten or a
dozen faculties and the various student
bodies mingle and intermingle in a spirit
of cooperation and mutual regard almost
unknown outside, and hitherto little known
‘within, the academic world.
The mere atmosphere, then, of a modern
university must energize and elevate all
those who come within its influence. But
the domain of this atmosphere is not
bounded by academic walls. It is not a
limited medium within, but is actually a
part of, the unlimited medium of the intel-
lectual world; for the modern university
has broken also with custom and tradition
in allying itself closely with the external
world of thought. Through interaction of
the intramural and the extramural spheres
of thought the instructor and the student
are kept face to face with the vantage
ground of contemporary life, whence they
may look forward as well as backward.
The modern university is an institution
of learning in the full sense of the word;
an institution wherein instructors teach
students, and wherein, reciprocally, to a
very important degree, students teach in-
structors; for that instructor is fossilized
who does not learn more per year from his
students, if they are worthy of the name,
than they learn from him. Together they
work diligently not only to become ac-
quainted with the known, but still more
diligently to penetrate the secrets of the
unknown. Among them there is a senti-
ment that condemns alike the instructor
who would impart knowledge by the meth-
od of the rotary calabash, and the student
who, with saturnine stolidity, would ab-
sorb only the information poured into his
ears. Dwelling thus at a university, not
apart from, but actually in, the world of

contemporary thought, students may best
fit themselves for the- world of contempo-
rary life; and while they may justly esteem
it a great privilege to graduate from an
historie college, or from a professional
school of international reputation, they
should esteem it a far higher privilege to
eraduate from a great university.
It should be observed also that the re-
sultant ideal which has been attained in
our best universities is not fixed but pro-
eressive, not inflexible but subject to im-
provement. It is a development whose
sources are seen in the earliest civilizations,
whose growth was dimly perceived during
the middle ages, and whose conscious ap-
preciation is a realization of the century
just past. The method which characterizes
this development is the method of science.
It dates essentially from the epoch of Gali-
leo and Huygens. It rose to a maximum
of brillianey in its interpretation of ma-
terial phenomena during the epoch of New-
ton and Leibnitz, and during the epoch of
Laplace and Lavoisier; and it has recently
illuminated: a new domain through the
labors of Darwin and Spencer. Galileo,
Newton and Laplace gave us a system of
the inorganic world; Darwin and Spencer
have given us a system which includes the
organic world as well.
The method of science has permeated all
regions of thought and animated all of the
commercial, industrial, political, social and
religious activities of men. Whether we
welcome it, deplore it, or indifferently ac-
quiesce in it, the fact seems undeniable
that the method of science and the doctrine
of evolution are the most effective sources
of the intellectual enterprise of our day.
Through anthropology this method and this
doctrine have given a transcendent interest
to the study of man; for they show that
man may not only investigate the rest of
the universe, but that he may, by the same
means, investigate himself. Consciously or
SCIENCE. 43
unconsciously, the terminology, the figures
of speech and the modes of thought of sci-
ence are being applied to all subjects and
objects of human concern. They have
penetrated the depths and the darkness
even of the polite literature of our times.
But while the ideal thus outlined appears
to be the effective, or working, ideal at
which we have arrived, it goes without say-
ing that it is not the only ideal entertained
by those whose opinions on academic ques-
tions are worthy of regard. On the con-
trary, many eminent minds deplore present
tendencies and write and speak regretfully
of the vanishing ideals of the past. Grave
publicists, accomplished men of letters and
subtle philosophers see little but danger in
the educational readjustments of recent
times. They deplore especially the decline
in popularity of those ancient studies long
called the humanities and the contempo-
rary rise and increasing recognition of the
newer studies. Culture, they seem to
claim, comes inevitably through the pur-
suit of the former, never through pursuit
of the latter. They go so far in some cases
as to decide at what point the study of a
subject ceases to be liberal and begins to
be illiberal, or professional. Give a student
by the ancient formula, their facile editors
say, that modicum of learning which would
otherwise be dangerous, stamp him with the
degree of A.B., and he becomes an aristo-
erat. They take a gloomy view of the rest-
less present and they are little hopeful of
the future; for they hint darkly of ‘the
bankruptey of science’ and of disasters im-
pending if we do not return to ancient
ideals.
Argument concerning these matters is
fruitless. Logie avails as little in an edu-
eational campaign as political economy
avails in a presidential campaign. Appeal
must be had to our sense of humor and to
the arbitrament of time. It may be ob-
served, however, that these apostles of

doubt and prophets of evil are slowly dis-
appearing. They are more numerous out-
side than inside academic walls, they are
less strenuous in large than in small col-
leges, and they are no longer dominant in
the best universities. From a philosophic
point of view they illustrate the action of
a most interesting and usually beneficial
sociological prine:ple. When consciously
applied this principle may be called the law
of rational conservatism. When uncon-
sciously apphed it may be called, in anal-
ogy with a great physical principle, the
law of conservation of ignorance. It is so
much more important for society to protect
itself against the follies of the unwise than
it is to profit by the improvements of the
wise, that progress comes, generally, only
painfully slowly. May we not entertain
the hypothesis that the contemporary op-
ponents of educational reforms have been
animated towards them rather uncon-
sciously than consciously? Having drunk
deeply at certain fountains of learning,
they appear to be sure that there are no
others. They seem to have been, and to
be, always reeeding. For more than a
thousand years, in fact, the gaze of most
scholars has been fixed so steadfastly on
the glories of the past that it has been pos-
sible to advance only by marching back-
wards.
Through the unconscious action of the
law of the conservation of ignorance we
are always in danger of disproportionate
estimates of educational values and of er-
roneous judgments in the larger affairs of
life. We involuntarily revert to precedent,
commending what is old, condemning what
Thus, to give a concrete illustra-
tion, fear and panic would be visible in our
faces if we did not understand the mythical
significance of the names Phobos and Dei-
mos lately applied to the moons of the
planet Mars; but very few of us would be-
tray the slightest mental disquietude at our

profound lack of knowledge of the prop-
erties of the atmosphere which is the me-
dium of communication between you and
me in this room. Thus, also, in spite of
the obvious aphorism that all men are hu-
man, they have been divided into human-
ists and non-humanists, Matthew Arnold,
for example, being one of the former, and
the founder of our John Tyndall Fellow-
ship being one of the latter. And stranger
still, one might infer from the slowness of
legal and constitutional reforms, and from
many current arguments opposed thereto,
that laws and constitutions are not made
by men for men, but that, in some mys-
terious way, men are merely experimental
material for the training of crafty lawyers
and sagacious politicians.
But we have broken irrevocably with the
past; not in the sense of disregarding the
rich heritage of experience from our dis-
tinguished predecessors, but in the sense
that their customs and traditions no longer
dominate us. We have corrected their
observations for geocentric parallax; and
we must now correct their observations for
anthropocentrie parallax, just as our suc-
cessors, if they prove progressive, will
surely correct our blunders and avoid our
errors. The need of corrections for an-
thropocentric parallax in educational af-
fairs is now widely recognized. It leads
to the investigations of Mosely Commis-
sions, to the conferences of the Association
of American Universities, and to the broad-
er conferences of world’s fair congresses.
It is the chief source of the educational
activities of our day. In these activities
are to be seen the most hopeful signs of
the times; for while agitation does not
necessarily mean progress, serene content-
ment is pretty certain to mean stagnation,
if not regress.
And the readjustment now going on in
the academic world must continue. It isa
part, simply, of the readjustment going on

in the intellectual world at large. We are,
so to speak, in a state of unstable equilib-
rium, wherein mental repose can be pur-
chased only at the price of mental somno-
lence. Great as have been the enlargement
and the appreciation of educational and
professional opportunities during the past
three or four decades, we may confidently
anticipate still wider enlargement and ap-
preciation in the future. New divisions
of knowledge may be expected to arise, and
old divisions may be expected to undergo
marked expansion, redistribution or
emendation. The so-called humanities,
especially, must be broadened, purified and
elevated if possible to the intellectual level
of the more highly developed sciences. It
is clear, indeed, that in any revision of the
humanities some matters may be redis-
tributed, if not discarded, with advantage.
The reckless amours and the clandestine
peceadilloes of ancient and modern royalty,
for example, should be transferred from
the historian and the novelist to the anthro-
pologist, the alienist and the pathologist.
Such humanities, and many others of like
kind, can hardly stand in comparison with
the constancy of the stars and the beauties
of harmonic analysis.
All these matters of controversy, how-
ever, belong rather to the lower than to
the higher life of a university. How a
student acquires elementary training is an
academic question in the narrower sense of
the word. The world cares little for edu-
cational ways and means unless they can
commend themselves by results. Attain-
ments must be tested by achievements and
proficiency must be proved by progress.
To rise to this standard of excellence is
the ideal of the higher life of a university.
It is only by the pursuit of, and in the real-
ization of, this ideal, that instructors and
students may keep pace with and contribute
adequately to the advancement of modern
knowledge. Those who would separate
SCIENCE. 45
theory from practice, those who would
draw lines of invidious distinction between
pure and applied science, along with those
who would mistake a part of archeology
for the whole of education, are all alike
inimical to the trend of current progress.
It is the highest function of a university
to cherish this ideal and to promote espe-
cially the arduous labors essential to fruit-
ful original research. Those who ean add
somewhat to the sum and substance of per-
manent knowledge by the establishment of
a physical, a social, an esthetic or an
ethical principle, are the greatest benefac-
tors of our race. Of the many who feel
drawn to this high calling, however, few
are destined for fame. Only those who
prefer the turmoil of conflicting thoughts
to the tranquility of inherited opinions,
who can bear alike the remorseless dis-
eipline of repeated failure and the pros-
perity of partial success, may hope to
attain renown. But, as those serve also
who stand resolutely and toil patiently at
their allotted tasks, so is there room in the
grand aggregate of human achievement for
the humblest as well as for the noblest of
investigators.
The ideals, then, of a modern university,
like the ideals of the intellectual world at
large, contemplate achievement and prog-
ress in all grades of work from the lowest
to the highest. They demand endless
patience and unflagging industry from all
who seek to rise above the dead level of
mediocrity. The opportunities now af-
forded for the pursuit of, for the acquire-
ment of, and for the advancement of, learn-
ing are greater than ever before. We are
the heirs of the ages. But along with an
increasing heritage there come increasing
duties and inereasing responsibilities. It
rests with us to show that we are worthy of
this heritage and able to meet these duties
and responsibilities. -This is the line of
endeavor we resume to-day, and the spirit

THE PRESENT STATE OF GEODESY.*
THE problems of geodesy, like those of
most sciences, enter upon new phases with
the accumulation of facts bearimg upon
them. The problem of determining the
amount of the earth’s compression was
added to that of determining the size of
the supposed sphere as soon as Newton had
demonstrated its oblateness. The contro-
versy to which Newton’s theory gave rise
was settled by the famous geodetic opera-
tions of the eighteenth century which fur-
nished the cardinal facts in regard to the
earth’s figure and size.
What may be regarded as the slow prog-
ress of a more precise knowledge of the
earth’s dimensions since that time must be
attributed to the difficulties inherent in the
problem.
In the first place the dimensional meas-
urements must necessarily be confined to
the continental areas which occupy but
three elevenths of the earth’s surface. The
configuration and relationship of these
areas make it impossible to girdle any sec-
tion of the earth by direct measurement.
Secondly, the admeasurement of these
areas is far beyond the reach of individual
enterprise and can only take place when
the practical needs of governments suggest
the utility of great mensurational surveys
which at the same time and without great
additional expense will furnish the data
required for a more perfect knowledge of
the spheroid. In making this statement
it is not forgotten that individuals and
covernments did undertake in all ages

measurements for the purely scientific pur-
pose of determining the size of the earth,
for the desire for knowledge on this sub-
ject may be reckoned coeval with intellee-
tual development of man.
Happily it may be said also that by their
collective action the governments of the
world have shown in recent times that it is
considered a governmental function to sup-
port and promote researches in this branch
of science. I allude, of course, to the ex-
istence of the International Geodetie Asso-
ciation. It will not be out of place to say
in this connection that the association exists
by virtue of a formal convention between
the participating governments, which are,
at the present time, the United States,
Japan and Mexico and all the European
nations save Portugal, Roumania and the
group south of the Danube No account
of geodesy would be complete that failed
to consider the aims and labors of this asso-
ciation. Its history is part of the history
of geodesy since 1861. At that time it
’ began its career as the Mittel Europaische
Gradmesung. In a few years it expanded
into an European association and in 1886
it became international.
It is not generally known that it was this
association which instigated the French
government to invite the world to establish
an international bureau of weights and
measures at Paris. Without detracting in
any way from the labors of Bessel, Clarke
and others in intereomparing geodetic
standards, the successful labors of the
bureau which in consequence was estab-
lished in Paris removed at least some of
the difficulties that were encountered by
the investigators in this branch of science,
and by those engaged in the practical work
of the measurement of the earth.
The history of geodesy is full of in-
stances of confusion and wasted energy due
to the lack of a common standard, and the
results of many are measures which would

at least have great historic interest are
utterly lost to us, because we can not make
even a respectable guess at the units used.
The adoption of an international unit of
length and its necessary auxiliary, a com-
mon thermometric scale, and the provision
which the various governments made for
the reference of their measuring apparatus
to a common unit was a step of funda-
mental importance.
The association as such has no control
over. the geodetic operations conducted by
the different governments. Its function is
to be the intermediary where cooperative
action is needed, and to discover and point
out along what lines the greatest need for
information exists.
In pursuance of these duties it has helped
to perfect the European systems of trian-
gulation by showing where missing links
should be supphed, not only by measure-
ment of angles and bases but also by addi-
tional astronomical observations. It has
made absolute gravity determinations with
all the accuracy demanded by modern sci-
ence and has caused suitable connection to
be made by relative measures between wide-
ly seattered pendulum base stations, and it
has instituted unique relative gravity meas-
ures, to which further reference will be
made. It organized and maintains the sta-
tions for observing the variation of lati-
tude in regard to which it should be re-
marked that it is the desire of the associa-
tion to continue the observations beyond
the year 1906, which marks the end of the
ten-year period for which that service was
tentatively organized. The association
strongly desires not only to continue but
to extend the service to the southern hemi-
sphere and other latitudes than those now
oceupied by the permanent stations, and to
obtain the cooperation of suitably situated
observatories in their endeavor to discover
the cause of the phenomena.
That the problem of determining the
SCIENCE. 47
earth’s dimensions could not be solved by
simply measuring two ares in suitable lo-
ealities was brought home to geometers by
the anomalous results obtained in the eight-
eenth century. For instance, according to
Lindenau the combination of the two Amer-
ican ares, Mason and Dixon’s, measured in
1764, and that of Peru, measured a quarter
of a century earlier, gave a value of one
five-hundredths for the earth’s compression.
The value derived from those measured in
Great Britain alone was about nine times
as great, or one fifty-fifth, while those
made in France, considered by themselves,
gave one one-hundred-and-fiftieth. It is
not now important to inquire whether these
differences are not in part due to the erudi-
ties of the methods of measurement em-
ployed. They were sufficiently real to
throw doubt on the belief that the earth
could be represented by a regular mathe-
matical figure. Finally, the existence of
local deflections of the vertical as affecting
the amplitude of ares was recognized, but
not taken into account save, perhaps, by
arbitrary exclusion of stations showing ex-
ceptionally large deflections.
The method of finding an osculating
spheroid from are measures remained in
its essence that of taking averages of meas-
urements reduced to the geoidal surface.
The differences between the observed direc-
tions of the vertical and those computed on
an assumed spheroid of reference were
treated as if they were accidental errors of
observation. At the present time it is the
aim of geodesists to assign to the deflections
their proper place in the computations and
to interpret them by discovering through
them and through gravity measurements
the manner of the distribution of masses in
the interior of the earth. Thus geodesy is
trenching on the domain of geophysics and
geology.
In India, in Europe and in the United
States the study of these deflections is re-

celving special attention. In the last-
named countries the junction and correla-
tion of the triangulation, which was for-
merly disjointed, makes it possible to take
up the study. Similarly in this country
the completion of the transcontinental are
and its connection with the lake survey tri-
angulation furnished the opportunity and
oceasion for adopting a standard datum of
geographical coordinates for the whole
country. This in turn furnished the de-
flections of the vertical referred to a com-
mon origin of coordinates on the same
spheroid and made it possible to begin the
study of the form of the geoid in this coun-
try over a very extended area.
The investigation has so far been extend-
ed over the eastern part of the United
States. Here as elsewhere it was found
that the curves of elevation of the geoid
above the spheroid reflect perceptibly the
visible topographic features.
A preliminary statement of the scope of
these investigations was recently given be-
fore the International Geographic Congress
by Mr. Hayford, the chief of the computing
division of the Coast and Geodetic Survey.
From it I quote as follows:
The conclusion that for the eastern half of the
United States and the adjacent portion of the
Atlantic the theory of isostasy is true to a con-
siderable extent is reasonably safe. The conclu-
sion that the depth within which the isostatic
compensation takes place is 205 miles is one
which may be modified considerably as the inves-
tigation proceeds.
The investigation thus far leaves the signs of
the corrections to the constants of the Clarke
spheroid of 1866 uncertain.
Mr. Hayford will give before this meet-
ing an account of the method devised by
him of computing the topographic correc-
tion. The task of computing this correc-
tion to a distance of 4,000 kilometers for
each of say 500 stations has been rendered
possible by this method, which is, therefore,
referred to by me as a distinet advance in
geodesy.
[N.S. Vou. XXI. No. 524.
It is hoped that the completion of the
study of the data now available in regard
to the deflections will serve as a guide to
the most effective use in the future of the
pendulum, and it is on this account largely
that pendulum observations have been for
the present deferred by the coast survey.
They are, however, being actively made by
other nations.
A new impetus was given to relative
gravity observations by the adoption of
short and light pendulums in place of the
heavy seconds’ pendulum. Aside from
their portability, their lightness insures
greater invariability for the knife edges,
simplifies the task of securing uniformity
of temperature and pressure in the metal
cases in which they are swung, and the ease
with which a low and constant pressure
can be maintained in the case insures the
continuance of the swing through so long
a period that the errors of the chronometer
or, other timepiece are eliminated. Thanks
to the efforts of the International Geodetic
Association, the widely scattered base sta-
tions have been connected with the central
station of the association at Potsdam, where
a long series of absolute gravity determina-
tions were brought to a successful conelu-
sion two years ago. The association has
available now the data from nearly 1,800
stations seattered over various parts of the
globe. A most interesting and valuable
extension of relative gravity measures to
the surface of the ocean was made two
years ago. The principle upon which the
new method depends is that if the atmos-
pherie pressure is determined at the same
time and place by means of a mercurial
barometer on the one hand and by the
temperature of the boiling point of water
on the other, the observed height of the ba-
rometer will be affected by gravity at the
place, while the result by the hypsometer
will be independent of it. According to
Dr. Hecker, who carried out the laboratory
JANUARY 13, 1905.]
experiments as well as the actual test at
sea, the suggestion that the two instruments
might be used for the determination of
differences of gravity was first published
in 1894 by Dr. Guillaume, of the Interna-
tional Bureau of Weights and Measures at
Paris. Dr. Mohn, of Christiania, success-
fully apphed the method by actual tests in
various places in Norway for the purpose
of determining the gravity reduction of
the barometer for meteorological purposes.
Doctor Hecker installed his apparatus on
a steamship and sailed from Hamburg to
Rio Janeiro via Lisbon, Portugal, and
Bahia, Brazil, and returned on another
steamer to Lisbon, making observations
both ways. The results of his observations
have been published and show:
1. That the intensity of gravity on the
Atlantic Ocean between Lisbon and Bahia
is nearly normal, and agrees with the theo-
retical values computed by means of the
general formula published by Helmert in
1901.
2. That the difference of gravity at sea
in shallow water and in deep water corre-
sponds approximately to the difference of
gravity between coast stations and inland
stations.
These results were submitted to the Geo-
detic Association at the last meeting.
Means were provided for another expedi-
tion and last March Dr. Hecker began his
journey, crossing the Indian Ocean and the
Pacific by way of Melbourne and Sydney
to San Francisco. Thence he recrossed to
Japan and China, and we may look for-
ward to an early statement of the results,
which are being awaited with deep interest.
As in the case of the pendulum already
referred to, there has been in the last dec-
ade a decided improvement and simplifica-
tion in instrumental means and methods of
work. It is only necessary to cite the in-
troduction of tapes and wires for primary
base measurement, the introduction of the
SCIENCE. 49
transit micrometer for the elimination of
personal equation in time determinations,
and of the leveling instrument, devised in
the coast survey, which is making its way
into more general use. With the use of
the latter there has just been satisfactorily
completed the first precise line connecting
the Atlantic, Gulf and Pacific mean sea
levels in the coasts of the United States.
In all countries the determination of the
mean sea level and the establishment of so-
called bench marks in the interior are being
actively prosecuted as they furnish part of
the required geodetic data.
In beginning I referred to the measure-
ment of continental areas. Let us see what
has been accomplished as to the extent of
areal measurement since Snellius intro-
duced triangulation into geodesy 289 years
ago. In our own hemisphere, so far as I
am able to learn, about the three-hundredth
part of one per cent. of the area of South
America has been covered ; of Mexico about
one per cent.; of the United States about
five per cent. Geodetically the British pos-
sessions in the western hemisphere are bar-
ren. We may say that less than three per
cent. of the western hemisphere has been
triangulated.
In the eastern hemisphere we find that
about forty per cent. of Europe has been
covered, but if we leave out Russia the per-
centage rises to eighty per cent. for the
rest of Europe.
The triangulation of Asia is furnished
by India and Japan, Java and Sumatra
and amounts to about four per cent.
Australia shows about two per cent.,
Africa about two and six tenths per cent.,
making a total for the eastern hemisphere
of about seven per cent.
If we exclude the north and south polar
regions a little over six per cent. of the
available land area has been triangulated,
or about one and one half per cent. of the
total surface of the globe. These figures
50 SCIENCE.
are accurate enough for the purpose for
which they were compiled, that is, to show
the relatively small area covered. There
is, however, another side to the picture, the
hopeful one. In South America the are
of Peru is being remeasured and extended
by the French government. As the work
is being carried out with the advice of
the most distinguished mathematicians of
France, the results will be, in their impor-
tance, out of all proportion to the extent
and area involved.
Mexico has made a brave beginning and
is working towards a connection with an
extension of the ninety-eighth meridian
measurement, of which the United States
has completed about three quarters of the
amplitude lying in her own domains. Work
on the Pacific coast are has been resumed
and it has nearly been completed from San
Diego to the Columbia River.
Two years ago the Russians and Swedes
jointly completed an are in Spitzbergen
between latitudes 76° and 81°. The Euro-
pean ares are being extended eastward by
Russia, and one must look forward to the
ultimate connection between the Russian
trianeulation at Astrakhan or Orsk and
the Indian triangulation, however improb-
able it may seem if looked at from a po-
litical view point.
In Africa the work of extending the
South African ares northward from the
Cape towards Alexandria is well under
way, and no doubt need be entertained that
the British and Germans will earry it
through.
A general review of this part of the
field of geodesy shows that while some
ereat geodetic measurements have been
completed or are approaching completion,
new ones are being undertaken under the
fostering care of different governments.
Reasoning from the experience of the
past, we may econelude that the solution of
one problem in geodesy will disclose the
[N.S. Vou. XXI. No. 524.
existence of another, and from the trend
of the investigations of the present that
other than purely mathematical and astro-
nomical sciences will be advanced by the
search for their solution.
That the progress of the branches of
science to which this section of our asso-
ciation devotes itself was greatly affected
by the problems of geodesy was pointed
out by Humboldt in language which may
fittingly conclude these remarks:
Except the investigations concerning the par-
allax of the fixed stars, which led to the discovery
of aberration and nutation, the history of science
presents no problem in which the object obtained—
the knowledge of the mean compression of the
earth and the certainty that its figure is not a
regular one—is so far surpassed in importance
by the incidental gain which, in the course of
long and arduous pursuit, has accrued in the gen-
eral cultivation and advancement of mathematical
and astronomical knowledge.

CHEMISTRY .*
Ir has been the custom of the retiring
officers to discuss the development of some
portion of that field of chemistry in which
they were most interested. Since the
president of the American Chemical So-
ciety will speak on physical chemistry to-
morrow night, it has seemed to me that I
might break with tradition and discuss the
future of physical chemistry rather than
its present or its past.
We have reached a eritical stage in the
development of the electrolytic dissociation
theory. The work of Kahlenberg has
shown that there are a number of facts
which we did not anticipate and which we
ean not explain satisfactorily at the pres-
ent time. The recent experiments of Noyes
show that the dilution law does not hold
for any strong electrolyte and that the

sanie empirical equation describes the be-
havior of binary and of ternary electro-
lytes. This last fact appears to be fatal
to all explanations based on the assumption
that electrostatic effects are the disturbing
factors. While the mutual attraction or
repulsion of two ions or of three ions may
easily change the dissociation formula for
a binary or a ternary electrolyfe, it is very
improbable that the changes will be such
as to make two radically different formulas
identical. Of course, the hypothesis of
hydrated ions gives us some leeway but
the outlook is not what it was five years
ago. It is too soon yet to say whether we
are merely to remodel the electrolytic dis-
sociation theory or whether we are to re-
place it by something else. My own opin-
ion is that reform is what is needed and not
revolution. It is evident, however, that
we have gone ahead too fast and that we
must test more thoroughly the premises on
which our conclusions are based. We know
of one error. The proportionality between
molecular weight and osmotie pressure
holds only for the cases in which the heat
of dilution is zero. This is stated clearly
in van’t Hoff’s original deduction of the
van’t Hoff-Raoult formula n/N —log
p/p,, but has been pretty generally over-
looked. Since the heat of dilution is rarely
zero in any actual case, our deductions as
to the molecular weights of solutes are
always somewhat in error. In the ease of
the metals of the alkalies and the alkaline
earths dissolved in mereury, the lowering
of the vapor-pressure due to the heat of
dilution is practically equal to that due
to the molecular weight, and we therefore
have the surprising result that the appar-
ent molecular weight is only about one
haif the atomie weight. One of the first
things we have to do is to eliminate this
source of error in all eases.
Another distressing feature in the quan-
titative physical chemistry of to-day is that
SCIENCE. 51
the field which. it covers is daily growing
less. A tenth-normal solution is now con-
sidered a concentrated one, and some people
are so extreme as to maintain that we can
not expect agreement between theory and
experiment for anything except infinitely
dilute solutions. To my mind a theory
which holds only for infinite dilution is
necessarily wrong. Here again one prob-
able source of error is easy to find. The
van’t Hoff-Raoult formula is deduced on
the expleit assumption that there is no
specifie attraction between solvent and
solute. If this assumption is wrong, it is
reasonable to suppose that the error thus
introduced would become less as the con-
centration approaches zero. Under these
circumstances the van’t Hoff-Raoult for-
mula might represent the facts at infinite
dilution without being a true formulation.
This is the case with another well-known
and important formula. The Helmholtz
and the Nernst equations, for the electro-
motive foree of concentration cells are
identical for infinitely dilute solutions and
for these only. The Nernst equation
ignores the coneentration of the undis-
sociated salt, while the Helmholtz formula-
tion does not. The two equations become
identical at the moment when the concen-
tration of the undissociated salt and the
disturbing factor due to it become zero,
that is, at infinite dilution. Since the
Helmholtz formula applies to all concen-
trations, the Nernst formula is necessarily
only approximately accurate. This has
been recognized explicitly by Planck,
though the point is often overlooked. It
is quite conceivable that the shortcomings
of the van’t Hoff-Raoult formula may be
due in part to theoretical inaccuracies and
that we have laid too much stress on ‘vari-
ations from the gas laws.’
If we introduce the conception of a
specifie affinity between solvent and solute
in certain eases, notably those in which the
52 SCIENCE.
heat of dilution is marked, we combine all
of what has stood the test with what is
good in Kahlenberg’s conceptions and I
believe that we are nearly ready to take a
long step forward. One point must be kept
in mind, however. Raoult’s experiments
preceded his formula. Before we can
hope to work out a satisfactory theory of
concentrated solutions, we must have ac-
curate measurements on concentrated solu-
tions and at present we have practically
none. We need experiments at constant
temperature on the compositions of co-
existent liquid and vapor phases for binary
systems with one volatile component and
with two volatile components. These
measurements are not easy to make and
that is one reason why they have not been
made. We have measured boiling-points
and freezing-points because they are easy
to measure; but for a theory of concen-
trated solutions the value of such measure-
ments is very small. This is because
we are then measuring the combined effect
of the change of the pressure with con-
centration and with temperature, whereas
we ought to study the two separately. Fur-
ther, if we are to express our results in
volume concentrations we must give the
volume concentrations of both components.
It would be absurd to pass from dilute to
syrupy solutions of sugar, for instance, and
to treat the concentration of the water as
constant. Personally, I believe that the
theory of concentrated solutions is rela-
tively simple and that the difficulties have
been chiefly of our own making. My own
experience with ternary mixtures confirms
me in this view. In developing a theory
of concentrated solutions we must also keep
in mind the actual properties of the com-
ponents, a thing which we have not done
in the past. Thus the dissociation equa-
tion for liquid chloral hydrate can not be
the same as that for liquid chloral aleohol-
ate because chloral is miscible in all pro-
[N.S. Vou. XXI. No. 524.
portions with alcohol and forms two liquid
layers with water. This is a perfectly
obvious fact, yet no reference to it is to
be found in any text-book on physical
chemistry.
In the last ten years the work of Rooze-
boom and others has brought the phase
rule to the front as a basis of classification
and as an instrument of research. The im-
portance of the phase rule is going to in-
crease very rapidly in the next decade.
The study of alloys has really only just
begun. Our knowledge of the carbon
steels is still very incomplete and unsatis-
factory. In fact, we know the constitution
only of a very limited number of binary
alloys. Nothing systematic is yet known
about the chemical properties of alloys
or about the conditions for electrolytic
precipitation. The variation of the engi-
neering properties, such as tensile strength,
torsional resistance, ductility, ete., with
varying concentration and varying heat
treatment is a subject which can only be
worked out satisfactorily with the phase
rule as a guide. On the basis of what has
been done it appears quite safe to predict
that we do not yet know one half the pos-
sibilities of our structural metals.
Quite recently the constitution of Port-
land cement has been established and we
owe this result to an application of the
phase rule. It will not be long now before
we get much clearer ideas on the causes of
the strength of cements and of the plas-
ticity of the clays. The time will soon
come in our engineering schools when the
subject known as ‘Materials of Engineer-
ing’ will have to be taught by the chemist
rather than by the engineer.
The applications of the phase rule to
petrography will be numerous and will
come soon. It is evident that no rational
classification of minerals ean be possible
until the constitution of the minerals has
been determined. The situation in regard
JANUARY 13, 190v.]
to petrography is much the same to-day as
it was in regard to alloys a few years ago
and we may reasonably expect as satisfac-
tory results from rocks as from metals.
More and more people are experimenting
with fused salts and the new geophysical
laboratory at Washington is planning to
study igneous rocks in the same thorough
way that van’t Hoff studied the Stassfurt
deposits. The problem is a difficult one
experimentally, but it can and will be
solved.
The classification of electrochemistry
under the phase rule is a problem of the
immediate future. Some work has been
done already, but it is confined to the dis-
cussion of the electromotive forces of cer-
tain reversible cells. What I mean is some-
thing vastly wider than this, the applica-
tion of the phase rule to all electrolytic and
electrothermal processes. Since electro-
chemistry is essentially chemistry, a classi-
fication which is of fundamental impor-
tance in chemistry must be equally neces-
sary in electrochemistry.
The extension of the phase rule to or-
ganic chemistry is an achievement about
which we like to dream, but the realization
of it seems far off. To treat a large por-
tion of organic chemistry as a system made
up of carbon, hydrogen and oxygen wiil
some day be possible; but at present we are
balked by so-called ‘passive resistances to
change.’ Theoretically methyl ether,
(CH,),0, and ethyl alcohol, C,H,OH, are
two modifications of the substance C,H,O
and they should be mutually convertible.
Practically they are not. Only one of the
three dibrombenzenes can theoretically be
the stable form. Actually, we can not con-
vert any one of them directly into either
of the other two.
In spite of all this there is really quite a
mass of material waiting to be worked up.
Reversible equilibrium between hydrogen
and oxygen can be realized at all tempera-
SCIENCE. 53
tures. Reversible equilibrium between car-
bon, carbon monoxide and carbon dioxide
is possible above 200°, while reversible
equilibrium between carbon, methane,
acetylene, ethane and hydrogen can be ob-
served above 1200° without catalytic
agents. Carbon monoxide and water re-
act at 480° in presence of copper. Methane
can be made from carbon monoxide and
hydrogen at 250° in presence of nickel,
while methyl alcohol can be changed to
earbon monoxide and hydrogen by zine
dust. The decomposition of alcohols into
aldehydes, or ketones, and hydrogen is re-
versible. Aldehydes can be changed into
carbon monoxide and paraffines, though the
reverse reaction has not been accomplished
satisfactorily. Methylal and acetal are
formed by a reversible reaction, while the
ester formation has been studied for years.
Formic acid decomposes into carbon mon-
oxide and water when heated by itself, and
into carbon dioxide and hydrogen when
heated in presence of rhodium. Starting
from carbon monoxide and caustic soda we
can make sodium formate, carbonate and
oxalate.
As yet only a few of these reactions have
been studied with care and we do not know
how many of them are reversible or what
are the temperature limits. We do not
even know whether colloidal metals act
more effectively than the pulverulent
metals, although it is very probable that
they do. While we ean not yet tell how
far we may be able to go, it is clear that
the attempt to apply the phase rule to
organic chemistry opens up a most inter-
esting field of research both as regards or-
ganic chemistry and as regards the theory
of catalytic agents.
The usefulness of the phase rule in study-
ing basic and double salts is being realized
more and more by our friends the inor-
ganic chemists. The recent work on the
changing solubility of the hydroxides of
54 SCIENCE.
many of the metals ealls attention to a
possibility of error which must not be over-
looked. In all eases of hydrolysis there is
always a possibility that equilibrium may
not be reached in weeks or months. The
only safe way is to reach the equilibrium
from both sides. In this way and only in
this way do we get any clue to the magni-
tude of the error involved and it is only
after we have done this that we are justified
in assuming that a reaction is irreversible.
The application of the phase rule to the
fractional erystallization of rare earths
would certainly lead to marked improve-
ments. There are few people who could
separate potassium and sodium chlorides
by fractional crystallization, getting out all
of each salt entirely pure. Even fewer
would be able to separate potassium sul-
phate and copper sulphate. In spite of this
we start in cheerfully on the fractional
erystallization of an unknown number of
elements having unknown properties. The
result of all this is that we reach a point
where further separation is impossible and
yet we do not know why. - This state of
things is really the fault of the physical
chemist and not of the inorganic chemist.
It is not to be expected that the inorganic
chemist can start in off-hand and apply
the phase rule to the study of basic and
double salts or of rare earths. Before this
can be done the physical chemist must work
out the methods and must be prepared to
sive explicit working directions, possibly in
the form of recipes.
It must also be clear to you that a study
of the conditions of existence of com-
pounds, atomic and molecular, is a pre-
requisite to any theory of valency,
In the past, reactions in organic chem-
istry have been studied by physical chem-
ists chiefly as examples of reaction velocity.
There are two other fields which will re-
ceive more attention in the near future,
namely, yields and irreversible reactions.

The question of yields is in a very bad
way. In Lassar-Cohn’s admirable book on
laboratory methods in organic chemistry
there is an enormous amount of valuable
material; but there is really very little in
the way of theory. Although we know
that a reversible reaction will run to an
end if the concentration of one of the re-
acting substances be kept practicaily zero,
surprisingly little use has been made of
this principle. We know that certain re-
actions take place better in dilute solutions
or at low temperatures or in certain sol-
vents, but in most cases we can not tell why.
In the pyridine method for introducing
acetyl or benzoyl groups the pyridine is
said to be effective because it is a weak
base; but it is much more probable that
it acts as a catalytic agent. We do not
know how far the dehydrating action of
certain reagents is simply a question of
vapor-pressure or how far there is a specifie
effect due to the particular reagent. The
action of sulphurie acid in the formation
of ether is something more than a dehydrat-
ing effect, and the same is true of the effect
of zine chloride in the synthesis of ethyl
ehJoride.
A single instance will be sufficient to
show the state of confusion that exists.
Anschiitz’s method of preparing certain
esters was to saturate the solution with
hydrochlorie acid gas and to allow the solu-
tion to stand overnight. Fischer improved
on this by adding less acid and by raising
the temperature. He boiled for two hours
and found that the hydrochlorie acid con-
centration could be reduced to three per
cent. without affecting the yield. There
the matter is left and we are led to look
upon a three per cent. concentration as
having special merits, whereas this is un-
doubtedly merely a result of boiling for
the arbitrary period of two hours. If
Fischer had boiled for one hour only he
would have had to use a stronger acid to

have reached equilibrium in the allotted
time. If he had boiled three hours, the
lowest permissible concentration of hydro-
ehlorie acid would undoubtedly have been
less than three per cent. Anschiitz, on the
other hand, worked at ordinary tempera-
ture and his solutions consequently needed
more acid and more time to approximate
to equilibrium. All of this is really first
principles and it is only one ease out of
many. If any one will try to classify and
explain the results given in Lassar-Cohn’s
book, he will find himself provided with
enough interesting research to last him the
rest of his natural life.
The second field for research to which I
have alluded is that of irreversible reac-
tions. In inorganic chemistry there are as
yet no well-authenticated cases where a re-
action starts and then stops short of equi-
librium. The results of Pélabon on hy-
drogen and selenium and of Hélier on hy-
drogen and oxygen have heen disputed by
Bodenstein and must for the present be
considered as wrong. In organic chemistry
we appear to have many such reactions,
typical instances being the formation of
nitro-benzene and the decomposition of al-
dehyde into methane and carbon monoxide.
While it is possible that these and other
reactions run to an end in infinite time, we
have not infinite time at our disposal, and
it may, therefore, prove profitable to find
out whether and how the apparent end-
point varies with varying initial conditions.
This work is desirable now and will become
necessary if we should ever revise our opin-
ions as to the theoretical possibility of an
irreversible equilibrium. By definition we
ean not determine the existence of an ir-
reversible equilibrium by approaching the
end-point from the two sides. It seems to
me probable, however, that we ean draw
conclusions from the reaction velocity. If
we are dealing with a case of a theoretic-
ally reversible reaction running practically
SCIENCE. 55
to an end, I can see no reason why the con-
centration of the decomposition products
should have any effect on the reaction ve-
locity, so long as we confine ourselves to
gaseous systems. If, however, we are deal-
ing with a theoretically irreversible reac-
tion which does not run to an end, the reae-
tion velocity would vary with the concen-
tration of the decomposition products.
It should be noticed that it will not do
to reason from the behavior of a system
in presence of a catalytic agent to that of a
system without a catalytic agent, since the
catalytic agent may displace the equilib-
rium. Thus ethyl aleohol is decomposed
by heated copper into aldehyde and hydro-
gen, while heated alumina changes it chiefly
into ethylene and water. It was the study
of organic solutes in organie solvents which
led Raoult to the formulation of his law.
It seems probable that a study of organic
reactions may lead to an entirely new class
of equilibria. If this happens it will throw
much light on the preceding problem be-
cause it is very difficult to explain some of
the peculiarities in regard to yields in or-
ganic chemistry so long as we are obliged
to postulate reversible reactions only.
The theorem of Le Chatelier has been
applied chiefly to heat and work effects,
but this is by no means the extent of its
usefulness. Wherever we get a reversible
displacement of equilibrium by lght, it
must be possible to make use of this the-
orem. The change of color of the silver
photochlorides is in accordance with the
theorem; but there seems to be no reverse
change in the dark. The simplest case
with which to. begin would appear to be the
formation of ozone. There seems to be a
contradiction here. Ozone is known to ab-
sorb ultra-violet light and yet it is believed
to be formed by the action of ultra-violet
light. Whether we are dealing with the
same sets of rays in the two eases is a point
that has not been settled. In fact. we do
56 SCIENCE.
not know definitely whether ozone is formed
by the action of ultra-violet light in the ab-
sence of electrical waves, though this is a
matter easily settled by experiment. We
know that ozone gives out light on decom-
posing, but we do not know anything about
the spectrum of this light. It is quite
probable also that we must formulate the
theorem of Le Chatelier more exactly than
we have hitherto done before we can apply
it suecessfully to the phenomena of light.
An instance based on electrical phenomena
will show what I mean. If a voltaic cell
be short-circuited the chemical change will
be such as to decrease the electromotive
force of the cell. If we do not keep the
cell at constant temperature the Joule heat
will cause the temperature to rise and this
may either raise or lower the electromotive
force of the cell. We are then really con-
sidering two phenomena, the electrical and
the heat effects. One may mask the other
completely.
In one case, at any rate, we know that
we can apply the theorem of Le Chatelier
to‘light phenomena. Suppose we have a
gas enclosed in a transparent adiabatic
vessel and concentrate upon it light of a
wave-length that is absorbed by the gas.
The temperature of the gas will rise and
equilibrium will be reached when the gas
has changed so that it no longer absorbs
light of that particular wave-length or
when the gas emits light of the same wave-
length and intensity as that which is acting
upon it. This emission by a gas at some
temperature of the light which it absorbs
at the same temperature is Kirchhoff’s law,
which thus appears as a special case of
what the chemists call the theorem of Le
Chatelier. To be frank, I do not now see
how we are to apply this theorem to the
phenomenon of phosphorescence, and yet
we are dealing with an absorption and an
emission of light. I venture to suggest
that it is to the application of the theorem
[N.S. Vou. XXI. No. 524.
of Le Chatelier that we must look for a
rational treatment of phosphorescence,
fluorescence, chemiluminescence, ete., rath-
er than to a theory of vibrating molecules.
It will be time enough to discuss the appli-
cation to radiations when we have solved
the simpler problem of the theory of cold
light.
A discussion of equilibrium relations
would not be complete without some refer-
ence to the future of thermodynamics in
chemistry. There are two radically dis-
tinct ways of considering the relation of
thermodynamics to chemistry. One is to
look upon thermodynamics as a mathemat-
ical shorthand. The aim of thermody-
namics is then to present a consistent and
formal treatment of the known energy re-
lations. In this case thermodynamics deals
with the past and not with the future; with
the classification of knowledge and not with
the discovery of new laws. This is the
point of view of most mathematical chem-
ists and it is because of this that we do not
turn to the mathematical chemist for new
ideas. There is another way of consider-
ing thermodynamics, namely, as an instru-
ment of research. It is not too much to
say that the mathematical chemist can
work out in a few hours or days results
which would take his less fortunate col-
league months or even years to obtain. At
present the race is to the tortoise and not
to the hare; but I can not believe that this
will always be so. Other things being
equal, the man who can handle his thermo-
dynamics will beat the man who can not;
but in order to have that take place thermo-
dynamics must be considered as an instru-
ment of research and not as a branch of
metaphysics. We must confess that the
mathematical chemistry of the past decade
has not done what it should have done and
that there is no immediate prospect of any
improvement. In the meantime we do not
despair. There are great possibilities in
JANUARY 13, 1905.]
the application of mathematics to chem-
istry and some day they will be developed.
So far we have considered problems in-
volving equilibrium only. When we begin
to study the conditions which make a reac-
tion possible and which govern its rate, we
are brought face to face with our need for
a satisfactory theory of catalytic agents.
We know experimentally the catalytic ac-
tion of many substances on many reactions,
but we have not even the first suggestion
of an adequate theory. This is a subject
of more vital importance than may appear
at first sight. I wish to call your attention
to two very important matters which de-
pend directly upon catalytic agents. The
first is the chemistry of plants. We can
make in the laboratory many of the sub-
stances which the plant makes. Some of
them, such as alizarine and indigo, we can
make more cheaply than the plant can, and
of a higher degree of purity. As yet we
can not make any of them in the way the
plant does, and this gap in our knowledge
will have to be filled by the physical chem-
ist, as the problem apparently does not
appeal to the organic chemist. The plant
does not use reverse coolers or sealed tubes;
it does not boil with sulphuric acid or fuse
with caustic potash; it has not metallic
sodium and chlorine gas as reagents. The
reagents on which the plant can draw are
air, water and a few mineral salts. As
catalytic agents it has heat, light, difference
of electrical potential, enzymes—and itself,
namely, living protoplasm. From the work
of Bredig and others we know that colloidal
metals, the so-called inorganic ferments,
ean be substituted for enzymes in some
eases. As we do not yet know our limita-
tions, it is quite possible that we can substi-
tute inorganic catalytic agents for the en-
zymes in all cases. If that proves to be
true we can then duplicate everything ex-
cept the plant itself, and we shall be ready
to determine how closely we can duplicate
SCIENCE. 57
the reactions of the plant. The experi-
ments of Sabatier and Senderens in France
are distinctly encouraging, even though
they do not carry us very far. By means
of nickel powder it is possible to reduce
acetaldehyde to aleohol with hydrogen at
30°. This is the best result that has been
obtained and it indicates the possibilities.
When we get a satisfactory theory of ecata-
lytic agents we shall undoubtedly be able
to duplicate many of the plant syntheses
and our failures will be interesting as
bringing us nearer to the most difficult
problem of all—that of life. Pending the
development of a satisfactory theory of
eatalytie agents, there is much to be done
in the way of experimenting. In view of
the fact that mixtures of two catalytic
agents often act more intensely than would
be expected from the behavior of each
taken singly, it would appear advisable to
determine the combined effects of inorganic
ferments and ultra-violet light.
The second problem, which would be
easier of attack if we had a satisfactory
theory of catalytic agents, is that of the
transmutation of the elements. This is
now admitted to be distinctly a scientific
problem, though not one in which we have
made much progress. It is usually as-
sumed that it is a very difficult problem.
While this may be true, we have not yet
reached the point where we are justified in
being certain of it. No one has ever at-
tacked the problem systematically and all
we can say is that the rate of change has
been small under any conditions that we
have yet realized. That is not surprising.
We should naturally expect a low reaction
velocity. The rate of change of radium is
so slight that it could not be detected by
any ordinary methods. The fact that we
have never observed any transmutation of
the elements does not prove that none has
taken place. We had been making dia-
monds artificially for years, even for cen-
58 SCIENCE.
turies, but nobody thought of looking for
them in east iron until after Moissan made
his experiments a few years ago.
If we aecept Lockyer’s conclusions as
to the state of things in the sun, we could
undoubtedly break up many of the ele-
ments if we could hold them long enough
at 6000° C. One difficulty is to get the
temperature, and of course we must be
cautious about conclusions based on simpli-
fied spectra. Many people have thought
that radium was to be the catalytic agent
which was to change all the elements; but
the recent work of Rutherford seems to
put an end to this idea. If radio-active
lead, tellurium and bismuth are merely
these elements plus the radium emanation
or one of its decomposition products, there
is very little evidence to show that any of
our well-established elements are undergo-
ing any change from contact with radio-
active substances.
Another possibility which has been sug-
gested is that we could change our elements
if we could pump energy into them and
change their energy content. This would
have to be done electrically if at all. I
have been told that Stas was busy during
the last years of his life trying to change
sodium into something else by an electrical
process. The difficulty is to pump energy
into the element. Passing a heavy cur-
rent through a metal produces no effect
that we know of other than to raise the
temperature. Taking the element in the
state of gas enables us to employ a higher
potential difference, but here the effective-
ness of the method is limited by the appear-
ance of the are. The first stage in the
problem would, therefore, be the attain-
ment of the highest possible potential dif-
ference without causing arcing. In view
of the remarkable insulating action of gases
under high pressure, it seems as though
the silent discharge through compressed
gases were the thing to try. The difficul-
[N.S. Von. XXI. No. 524.
ties people had in proving the dissociation
of water at high temperatures makes us
realize the possibility that we might decom-
pose our elements and never know it, owing
to the recombination taking place at once.
If we are to simplify our elements by
pumping energy into them, it appears that
we should work with gases under high pres-
sure, with the highest potential difference
compatible with the absence of sparking,
and with some application of the principle
of the hot-cold tube.
While the methods of extremely high
temperature and of high electrical stress
have much to commend them on paper,
they are liable to fail owing to the diffi-
culty of attaining the proper temperature
or the proper electrical stress. The ideal
method would be to find a catalytic agent
which would accelerate the rate of change
and which would eliminate what we should
then call the instable elements. Since
there is no immediate prospect of our being
able to predict the suitable catalytic agent
and the conditions under which it is to be
used, we must ask ourselves what is the
scientific method of attacking the problem
of the transmutation of the elements.
The answer is a simple one. We must
start with the simplest case, study that
thoroughly, and work up gradually to the
more difficult tasks. We should begin with
the cases in which we know a change is
possible and should study the allotropic
forms of the elements. At present our
knowledge of these is disgracefully incom-
plete. We know a little about sulphur,
phosphorus, carbon, selenium and tin; but
even for these few elements our knowledge
is incomplete and it is especially unsatis-
factory in matters bearing on the rate of
change. In most eases the change from
one allotropic form to the more stable one
is fairly slow. It is not even easy to get
large amounts of gray tin. On the other
hand, Saunders discovered, quite by ac-
JANUARY 13, 1905.]
cident, that there were a number of sub-
stances, notably quinoline, which convert
amorphous selenium into the more stable,
black, metallic modification. It is probable
that similar results could be obtained with
other elements. Kastle has shown that
the rate of change of yellow mercuric
iodide into the red form varies enormously
with the nature of the solvent. The first
thing that we need is a systematic study of
the allotropic forms of the elements, con-
sidering reaction velocity as well as equi-
librium. We next take up cases where the
change from one form to another can be
made increasingly difficult. The three
disubstituted benzene compounds, as I have
already said, are to be considered as dif-
ferent modifications, only one of which can
be stable as solid phase at any given tem-
perature and under atmospheric pressure.
According to the text-books o-phenol sul-
phonie acid changes readily into p-phenol
sulphonic acid on heating. When bromine
acts on phenol in the cold, p-bromphenol
is formed, while o-bromphenol is formed
when the reaction takes place at 180°. I
have not been able to find any record of
the p-brom compound changing into the
o-brom compound on heating; but the ex-
periment is worth trying. When we come
to the three dibrombenzenes, we have a
case where we know that the three forms
are identical in composition and where
there is certainly some sort of an equi-
librium at the time of formation because
the relative amounts of the modifications
ean be changed by varying the conditions
of preparation. In spite of all this we
know no way of converting two of these
compounds directly into the third. We
could undoubtedly do it if we could raise
the temperature high enough, just as we
could also convert the elements. It is as
yet impossible to attain the temperature
at which the elements change rapidly, while
secondary reactions interfere in the case
SCIENCE. 59
of the organic compounds. So long as we
can not change the two less stable forms of
any disubstituted benzene compound into
the most stable form, there is no reason
why we should expect to succeed in what
may, perhaps, be the impossible task of
simplifying the elements.
Summing up, the future developments
in physical chemistry will comprise a
theory of concentrated solutions, further
applications of the phase rule and of the
theorem of Le Chatelier, a systematic study
of organic chemistry, and a theory of
catalysis. Wiper D. BAncrort.
REPORTS OF COMMITTEES.
Tue following reports of committees
were presented to the council. They were
accepted and ordered printed:
On the International Congress of Americanists.
“The International Congress of Americanists
held its fourteenth biennial meeting in Stuttgart.
Germany, August 18-23, 1904. On June 1, 1904,
I received a communication from you announcing
my appointment as the representative of the
American Association for the Advancement of
Science at this meeting. The designation was
gladly accepted, as it had already been arranged
that I should attend the congress on behalf of the
Smithsonian Institution.
I now have the honor to report that the meet-
ing was in every way a most gratifying success
and that the representation of the American As-
sociation was duly recognized and published in
the official bulletins of the congress. The attend-
ance was largely German, but representatives
from a dozen other countries were present and
took an active part in the proceedings. The
papers presented related almost exclusively to
American history and anthropology and especially
to South American subjects. The Germans as
well as the French have given very great atten-
tion to investigations on that continent.
The next meeting of the congress is to be held
at Quebec in August, 1906.
Very respectfully,
W. H. Homes.
On Anthropometry.
The committee beg to report that individually

anthropometric work during the past year. It
was not feasible to arrange an anthropometric
laboratory last year at St. Louis, but this year
excellent arrangements have been made in con-
nection with the psychological laboratory of the
University of Pennsylvania. Measurements of
the members of the association are being made by
Messrs. V. A. C. Henmon, F. Bruner and G. C.
Fracker, with the cooperation of Professor Thorn-
dike, Dr. Woodworth and members of the com-
mittee. The chairman of the committee is ma-
king an extended study of American men of
science; two papers have been published on the
subject and there is now in press a ‘ Biographical
Directory of American Men of Science,’ containing
much material that can be used. We may call
special attention to the Anthropometric and
Psychometric Laboratory of the Louisiana Pur-
chase Exposition, arranged by Dr. McGee, head
of the Department of Anthropology. The labo-
ratory, under the direction of Dr. Woodworth, as-
sisted by Mr. Bruner, made measurements of
about 1,000 representatives of different races,
especial attention being paid to the native races
of the Philippine Islands.
We ask that the committee be continued and
that an appropriation of fifty dollars be made
for the expenses of an anthropometric laboratory
at the next meeting of the association.

On Cave Fauna.
Owing to the absence of the secretary of your
committee in the caves of Cuba during the last
meeting of the association, a report on progress
was omitted at the St. Louis meeting.
Since the last report the following papers based
in part at least on material collected with the
grant of three years ago have been published:
1. ‘Report on the Fresh-water Fishes at West-
ern Cuba.’ Bull. U. 8. Fish Comm. for 1902,

tion in Old Age.’ Mark Anniversary Volume,

Number five is the most important of these and
gives a complete account of the eyes of the largest
of our blind fishes. Further work on this form
should consist in noting the changes of the eyes
in individuals reared in the light.
Several papers are in preparation.
Several years ago a Mr. Donaldson died in Scot-
land, owner of a farm of somewhat over 182 acres
of land near Mitchell, Ind. He was apparently
without legal heirs. Suit was brought by the
state of Indiana to have this farm escheat to the
state. The suit was contested by Scottish heirs
of Mr. Donaldson, but was won by the state. This
farm is in the midst of the cave region of the
Cuba,’
JANUARY 13, 1905.]
Ohio Valley, to which belong Wyandotte and Mam-
moth caves, and is much more ideally adapted for
experimental work with cave animals than either
of the larger caves. On it are easily accessible
some very large rooms provided with water. On
it are the only entrances to an underground
stream which I have followed over a mile by
actual measurement and from which all of my
material of Amblyopsis was obtained. Finally
on it the stream comes to the surface under condi-
tions that make the farm admirably adapted for
surface ponds and pools to rear cave animals in
the light.
The American Association at its Washington
meeting passed resolutions asking the state of
Indiana to set this aside for a state reservation,
and part of it for an experimental farm for the
investigation of cave animals, ete. In the winter
of 1902 the state legislature passed a bill in part
as follows:
“The title of all such lands shall be and remain
in the state of Indiana, and such lands shall be
devoted to educational purposes.
“The control and management of all such lands
shall be vested in the trustees of Indiana Uni-
versity and such lands may be used by said trus-
tees for any proper educational purposes.
“Said board of trustees may in its discretion
set off any portion of such grounds to the use of
the state board of forestry or to that of Purdue
University, or any other educational or scientific
institution of the state.”
In the meanwhile the heirs appealed the suit
to the supreme court of Indiana which also ruled
in favor of the state in August of 1903. ‘lhe
heirs thereupon asked the same supreme court to
grant them a new hearing before itself and there
the matter has been suspended for over a year.
It seems very probable that this farm will ulti-
mately pass into the possession of the Indiana
University and can then be used for experimental
work with cave animals.
I have personally received a grant from the
Carnegie Institution which enabled me to make
further attempts to secure the embryological ma-
terial of the Cuban blind fishes, without, however,
being entirely successful in securing this much-
desired series of embryos.
The most notable and systematic piece of cave
work so far undertaken is in preparation by my
assistant, Mr. A. M. Banta. He is making a phys-
ical and biological survey of Mayfield’s cave,
situated but five miles from my laboratory. He
has determined the distribution of animals in the
cave, the per cents. of the total cave fauna that is

accidental, occasional or permanent. He is
working in the interrelation of these forms and
determining the modifications of the permanent
members of the fauna to adapt them to cave life.
This piece of work will form a base line for future
work with the fauna of caves, and it is very de-
sirable that Mr. Banta be enabled to make
similar studies of a few selected caves in the
various cave regions of America.
It is recommended that the committee be con-
tinued and that an appropriation of $100 be made
to continue the work of the committee.

On Indexing Chemical Literature.
The committee on indexing chemical literature,
appointed by your body at the Montreal meeting
in 1882, respectfully presents to the Chemical Sec-
tion its twenty-second annual report, covering the
eighteen months ending December 1, 1904.
Works Published:
‘A Select Bibliography of Chemistry, 1492-
1902,’ by Henry Carrington Bolton, Second Sup-
plement. Smithsonian Miscellaneous Collections,
No. 1440, City of Washington, 1904.
This supplement brings down the literature of
chemistry from the close of the year 1897 to the
close of the year 1902. The author died while the
publication was in press and most of the proof-
reading, as well as the preparation of the index,
was done by Mr. Axel Moth, of the New York
Publie Library.
In the Arbeiten aus dem Kaiserlichen Gesund-
heitsamt, volume 21, pages 141 to 155, appears a
critical bibliography of sulfur dioxid in wine, by
W. Kerp:
Indexes on the literature of gallium and of ger-
manium, by Dr. Philip E. Browning, of New
Haven, Conn., have been completed and accepted
by the Smithsonian Institution for publication.
An index to the literature of radium and radio-
activity has been completed by Dr. Chas. Basker-
ville and Mr. Geo. F. Kunz, and is expected to
appear in a bulletin of the United States Geolog-
ical Survey, as an appendix to a paper by Mr.
Kunz on radium.
An index to the literature of solubilities, 1875—
1903, by Mr. Atherton Seidell, of the Bureau of
Soils, is now in the hands of the committee.
The index to the literature of glucinum by Pro-
fessor Chas. E. Parsons, of New Hampshire Col-
lege, Durham, N. H., has been completed.
62 SCIENCE.
As is well known for a number of years such
bibliographies as have been recommended by their
committee have been accepted by the Smithsonian
Institution for publication in its ‘ Miscellaneous
Collections.’ It has thus been possible to put into
the hands of specialists and others valuable in-
dexes which could not otherwise be rendered ac-
cessible.
That it is not deemed possible for the Smithso-
nian Institution to continue this work appears
from the following extracts from correspondence
with Mr. S. P. Langley, Secretary of the Institu-
tion:
“The institution has found it necessary to dis-
continue for the present the publication of sepa-
rate indices to the literature of the various chem-
ical elements.
“The resources of the Smithsonian Institution,
as is well known, are limited, and must be dis-
tributed over a very considerable variety of in-
terests. When, failing congressional aid, it
seemed that the project of the International Cata-
logue of Scientific Literature could not proceed
without the establishment of an American re-
gional bureau, I decided to assume this on the
part of the Smithsonian Institution, and the allot-
ment made for this purpose is practically all that
can be spared for any current indexing work.
“The various bibliographies to chemical ele-
ments and other chemical indexes could not, ap-
parently, have veen projected upon a plan that
would fall in with this catalogue, since at the time
they were begun no one had the catalogue in mind.
Accordingly, I find that the earlier ones come down
to 1887, 1893, 1896 and 1900, and a more recent one,
thorium, down to 1902. This brings up the entire
question of retrospective indexing and_bibliog-
raphy. previous to the date 1901, designed to cover
the period prior to the beginning of the interna-
tional catalogue. Such a project for all science
should, of course, only be taken up after mature
deliberation, and could only be carried through by
international cooperation. Meanwhile it seems
prudent for the institution to await a careful
consideration on the part of all interested in the
whole subject, chemistry, being of course, but one
of the large group of sciences whose workers must
be considered. In view of these considerations,
the importance of which you will, I am sure, rec-
ognize, I am constrained to leave the entire matter
in abeyance for the present.”
In view of the above it may be questionable
whether the work of this committee has not been
completed as far as it is possible to carry out the
oflices for which it was originally constituted. It

may, however, be wise to continue it for another
year, to await developments.
In conclusion, references should be made to the
great loss sustained by the-committee, the sec-
tion and the association, in the death on November
19, 1903, of Dr. Henry Carrington Bolton, who
from the first appointment of this committee has
been its chairman. The work of Dr. Bolton in the
field of chemical and alchemical bibliography
needs no encomium; it is invaluable to all work-
ers in these fields.

On Electrochemistry.
A pure iridium electrode was purchased, and
some rhodium powder. It was deemed advisable
to precede the electrochemical portion of the in-
vestigation by a study of the chemical phenomena
caused by these metals when no current passed.
With this in view experiments have been made on
the action of these metals on formic acid. These
have confirmed the qualitative results of Deville
and Debray, that the decomposition products are
essentially carbon dioxid and hydrogen under
these circumstances and not carbon monoxide and
water. The reaction starts at a higher tempera-
ture than one would have supposed from the
statement of Deville and Debray as to ‘gentle
heating.’ The rate of decomposition of liquid
formic acid is constant when the decomposition
products are allowed to pass off, but there is need
of the further study of the behavior of the acid
in a closed space. This will be taken up next, and
after that the electrolysis. The effect of the iri-
dium on the chemical and electrochemical equi-
librium between chlorine and water will also be
studied. For this work your committee asks for a
grant of an additional sixty dollars.
The committee begs leave to report progress.
Respectfully,

On Grants.
The committee on grants recommended that the
following grants be made for the year 1905:
To the Committee on Anthropometry, $50.
To the Committee on Electrochemistry, $60.
To the Committee on Cave Fauna, $100.
To the Concilium Bibliographicum, $100.

On the Walter Reed Memorial.
At a meeting of the association held in Wash-
ington, a committee was appointed, of which I was
made chairman, to take such measure as might
be found wise for securing a permanent memorial
of Major Walter Reed, U. S. A., in recognition of
his important services to humanity. Acting
under this authority, it was at length found ex-
pedient, after several preliminary meetings, to
form an incorporation in the city of Washington
to hold such funds as might be contributed. This
incorporation is now endeavoring to raise the sum
of $25,000, of which the income may be paid to
Mrs. Reed and the principal may be devoted to a
permanent memorial of Dr. Reed. More than
$13,000 has been subscribed already, a large part
of this amount coming from the medical profes-
sion. This is all in addition to the action of Con-
gress, which has given, on the representations of
your committee, an unusual pension to Mrs. Reed.
The effort is now making to secure the additional
sum of $12,000, and the cooperation of all mem-
bers of the American Association for the Advance-
ment of Science is urgently desired.

Elements of the Differential and Integral Cal-
culus. By W. A. Granvitte. Boston, Ginn
and Company. Pp. xiv + 463.
A characteristic feature of mathematics in
the last half century is the increasing atten-
tion paid to the foundations and rigorous de-
velopment of this science. In analysis this
movement began with Gauss, Cauchy and
Abel in the early years of the nineteenth cen-
tury and found its greatest exponent in Weier-
strass. The movement thus begun has been
continued by such men as Riemann, Dede-
kind, Hankel, Cantor, Jordan, Dini, Stolz,
Harnack, Peano and a host of younger men.
As a result of these investigations it was
found that much of the reasoning hitherto
employed and in current use among mathema-
ticians was either worthless or required to be
:
JANUARY 13, 1905.)
modified, restricted or completed. It thus be-
came necessary to rewrite textbooks on an-
alysis or to prepare new ones more in harmony
with the new teachings. In this way arose
the new edition of Jordan’s ‘ Cours d’ Analyse’
and Harnack’s edition of Serret’s ‘ Calcul,’
as well as the new works of Stolz, ‘ Allgemeine
Arithmetik, and ‘Grundziige’; Tannery,
‘Théorie des fonctions d’une variable’; Dini,
‘Fondamenti per la teorica delle funzioni di
variabili reali,’
In England and America more progressive
teachers have felt for some time the need of
a modern text-book on the calculus, which is
at once rigorous and elementary. The task
of writing such a work is not easy. On the
one hand, it is necessary to avoid the worth-
less and even vicious forms of reasoning which
mar so many elementary treatises and which
are simply intolerable to one educated accord-
ing to modern standards of rigor. On the
other hand, the author must not introduce
subtilties of reasoning and logical refinements
beyond the needs and comprehension of those
who are to use the book.
The volume under review is an attempt to
solve this difficult problem. To our mind the
efforts of its author have been abundantly
crowned with success. In perusing Dr. Gran-
ville’s book one feels throughout that the
author has in mind the requirements of mod-
ern rigor. The demonstrations, it is true,
often rest on intuition; but this is necessary
in a first course, as all will admit. They are,
however, usually correct as far as they go, and
free from the defects we have mentioned
above. We believe the present volume is
eminently a safe book to put in the hands of
the beginner. He will get no false notions
which afterwards will have to be eradicated,
with much difficulty; he will, on the other
hand, acquire a considerable acquaintance
with the principles of the calculus and a good
working knowledge of its methods.
We make now a number of criticisms and
suggestions.
The definition of limit given in § 29 is not
the one given by Cauchy and Weierstrass and
now universally accepted. Looked at care-
fully, we see it supposes that all variables are
SCIENCE.
65
functions of an auxiliary variable, the time.
This leads to unnecessary complications in
the definition of the limit of a function in
§ 32. We believe the strict Weierstrassian
definition should be given and used. As an
aid to comprehension, the author’s notions in
these articles might prove useful. In § 34 the
notion of a graph is explained; but not with
sufficient care, to our mind. How is the reader
to know from their graphs that x and log «
are continuous functions? The three proper-
ties of the exponential function given in this
article result from their arithmetical proper-
ties and not from their graph, as the author
seems to imply.
The definition of the derivative given in
§ 41 is not satisfactory; what the author really
defines is the differential coefficient at a point.
It is their aggregate that forms the derivative.
In §55 the author has avoided an error
which is very prevalent. His passage to the
limit is, however, not completely justified. He
has yet to show that
ca AG fe NO
Saline = alin ;
Av=0 Av Axr=0 Ax
The demonstration in § 56 should, it seems
to us, be replaced by a simpler one. The au-
thor obtains the equation
_ dy dx
a dx dy )
and then remarks:
if dx/dy + 0, we have
He should see that there can be no need of
making the further assumption, dxr/dy +0:
for if it were, the equation (1) could not exist.
In §133 the author introduces a double
limit without any explanation. As_ such
limits are used in connection with double in-
tegrals, § 231, seg., they should be explained
with care. The footnote on page 194 is un-
intelligible to us and certainly will give rise
to misapprehension.
The theory of total differentiation does not
meet our approval at all. The author has
treated the subject from the standpoint that
the variables x,, x, --- 2, are all functions
n
66 SCIENCE.
of some one variable. Instead of true total
differentials, he gets total derivatives. The du
in $187 are not total differentials, but differ-
tials of functions of one variable. In the dif-
ferentiation of implicit functions the author
assumes merely the existence of the partial
derivatives. He should assume also their con-
tinuity. The form of demonstration is bad,
as it requires him to assume (tacitly) the ex-
istence of the very thing he is seeking, viz.,
dy/dx.
In the treatment of envelopes, § 141, the
author does not as usual give sufficient condi-
tions for the validity of his reasoning, but
contents himself with the vague statement in
a footnote that the process is all right ‘in all
applications made in this book.’ This blemish,
which a few lines will remedy, should be re-
moved in another edition. The definition of
an infinite series given in § 147 is not felici-
tous. In avoiding the lax definition usually
given the author has gone to the opposite ex-
treme. The simplest way seems to be to con-
sider
a,-+a,+a,+, ... in inf.
as a symbol to which a meaning is attached as
to other symbols, as > <=, ete. The solu-
tion of Ex. 3, § 152, is not quite rigorous, as
it postulates the covergence of G. In § 160
undefined arithmetical operations are per-
formed on series.
We can not agree with the author that the
remainder in Taylor’s series for several vari-
ables is too complicated to be given. The
treatment of maxima and minima can be made
much more complete without complications or
difficulty. The reasoning given at the bottom
of page 248 can be made not only ‘ plausible,’
but entirely conclusive, using no more space
that that required by the author.
In the reduction of indefinite integrals the
author proves the trivial formule
f(a + dv— dw) = foaw + fa — faw,
faa— a fae,
but omits entirely the demonstration relative
to the transformation of the variable. This
is all the more surprising as this transforma-
[N.S. Vox. XXI. No. 524.
tion is constantly employed, even in establish-
ing important theorems. Two chapters,
XXIX. and XXX., are devoted to definite
integrals. In the first we arrive at the notion
of a definite integral by means of the notion
of area; in the second, by means of the limit
of asum. In our opinion the first treatment
is not only superfluous, but should he entirely
omitted on several counts.
The relatively few blemishes in this work,
the reviewer is glad to state, will be removed
in the next edition. JAMES PIERPONT.

The Study of the Atom, or the Foundations
of Chemistry. By F. P. Venasie. Easton,
Pa., The Chemical Publishing Co. Pp. 290.
The history of an important scientific theory
is an interesting study, where it is possible,
as it often is, to trace the orderly development
of that theory from stage to stage. The evo-
lution of the atomic theory is a subject which
has claimed the attention of many writers,
and the story has been told so often and so
well in works on the history of chemistry, that
one wonders whether it is not familiar to most
chemists. A careful perusal of this book does
not disclose any new point of view, or any-
thing new in the method of treatment, though
the matter is generally presented in a satis-
factory manner, especially Chapter V., which
deals with the periodic system. In the last
chapter of the book the author considers the
most recent hypotheses regarding the constitu-
tion of matter by J. J. Thomson, Rutherford
and others. The book is generally clear, con-
servative in tone and, on the whole, well-pro-
portioned, though 75 pages, or one fourth of
the contents, seems rather too much to de-
vote to the conception of the atom before the
time of Dalton, especially as this material
must be taken entirely from secondary sources.
The book may be commended as a good sum-
mary for students. BE. T. AntEn.
SOCIETIES AND ACADEMIES.
NEW YORK ACADEMY OF SCIENCES. SECTION OF
GEOLOGY AND MINERALOGY.
Tue section was called to order at 8:15 P.M.,
November 21, 1904, with Vice-president Kemp
in the chair and forty persons present.
JANUARY 13, 1905.]
The first paper of the evening was by Pro-
fessor J. J. Stevenson, upon ‘ The Island of
Spitzbergen and its Coal,’ and was illustrated
by lantern slides. In introducing his subject,
the speaker described briefly the coast of
northern Norway and its geology, and referred
in some detail to Bergen, Hammerfest and
other cities. Spitzbergen was then taken up,
and its coals and their geological relations
were passed in review. The coal beds are of
Jurassic age, and the coal is peculiar in that
it partakes of the characters of the lignites as
well as of the true coals.
The second paper on the program was by
Professor James F. Kemp, on ‘ The Titanif-
erous Magnetite in Wyoming. On account
of the lateness of the hour, the speaker pre-
sented his topic only in abstract. The mag-
netite occurs in two places, fifteen and twenty
miles north of Laramie, Wyoming, the former
and smaller occurrence being near the Shan-
ton ranch, the latter and larger being on Chug-
water Creek. Both are in wall-rock of an-
orthosite which is practically indistinguishable
from anorthosite occurring in the Adiron-
dacks. The ores range from 20 per cent. to
40 per cent. TiO,. Thin sections show that
they contain green spinels, and one slide pre-
sents much olivine. They can be most reason-
ably explained as intrusive dikes. In this
view the speaker agreed with Waldemar Lind-
gren, who has published a brief note regarding
them. James F. Kemp,
Secretary pro tem.
Tue section held a special meeting Decem-
ber 2, 1904, with Vice-president Kemp in the
chair and two hundred members and visitors
in attendance. The meeting was called to
order at 8:25 p.m. and the program of the
evening was at once taken up. This consisted
of a lecture by Professor Albrecht Penck, of
the Imperial University at Vienna, who is an
honorary member of the academy.
The speaker discussed ‘ The Glacial Surface
Features of the Alps,’ and gave a brief sum-
mary of some of the results of the twenty
years of masterly work which has been done
by him and under his direction in the Tyrol.
Professor Penck described in popular language

the nature of the valleys of the Alps and
showed by means of lantern slides and a dia-
gram how the glaciers have widened and
deepened portions of their rocky basins and
produced lakes.
After a vote of thanks to the distinguished
guest of the evening, the section adjourned.

THE PHILOSOPHICAL SOCIETY OF WASHINGTON.
Tue 592d meeting was held December 10,
1904.
The first paper was read by invitation by
Mr. H. H. Kimball, of the Weather Bureau,
on ‘ Variations in Insolation and in the Polar-
ization of Blue Sky-light, during 1903 and
1904.2. Observations with an Angstrém pyr-
heliometer have been maintained by the
Weather Bureau at Washington since April,
1908. Comparison with previous observations
at Providence, R. I., and Asheville and Black
Mountain, N. C., indicate that the quantity
of solar radiation reaching the surface of the
earth on clear days during 1903 was consid-
erably less than during 1902 and 1904, the
deficiency from April to September being 16
per cent. as compared with 1902, and 9 per
cent as compared with 1904.
Observations with a Pickering polarimeter
indicate that there have been corresponding
fluctuations in the polarization of blue sky-
light, the percentage of polarization at a
point on a vertical great circle passing through
the sun and 90° from it, having averaged
49.6 per cent. from May to October of 1904,
as compared with 40.6 per cent. during the
same months of 1903.
The work of the astrophysical observatory
of the Smithsonian Institution and numerous
European observations were quoted, showing
similar deficiencies in insolation, in the trans-
missibility of the atmosphere, and in the
polarization of blue sky-light, during 1903.
The subject was considered to be one well
worthy of investigation by meteorologists.
Mr. J. F. Hayford, of the Coast and Ge-
odetic Survey, presented some recent results
on ‘The Computation of Deflections of the
Vertical from the Surrounding Topography.’
68 SCIENCE.
Deflections may be due to irregularity of
density within the earth or to attraction of
parts of the earth above the surface of the
mean spheroid. By an ingenious method,
partly graphical, the author had found it prac-
ticable to take account of the influence of all
known topographical features on the plumb-
line at more than 200 stations; it is usually
necessary to consider all the land-masses with-
in 2,500 miles of the station. When these
computed deflections from known causes are
combined with the deflections found from
geodetic measurements, the quantities to be
accounted for by irregularities within the
earth’s surface are usually much greater than
had been supposed heretofore.

DISCUSSION AND CORRESPONDENCE.
INTERESTING AND IMPORTANT FACTS.
In Powell’s ‘Truth and Error’ a_philo-
sophie distinction is made by giving special
[N.S. Vou. XI. No. 524.
definitions to the terms property and quality.
A property is an essential characteristic con-
sidered in itself; a quality is a characteristic
considered in relation to man. Thus the
ductility of iron is a property; its utility a
quality. The form and coloration of a tree
are properties; its beauty or ugliness is a
quality. Iron’s property of ductility, when
thought of in connection with human needs,
is a factor of its quality of utility; and the
properties of the tree, when viewed from the
standpoint of man’s esthetic sense, are quali-
ties. This simple distinction is of far-reach-
ing application, because properties are the
domain of science and qualities the domain
of art. Pure science (with a reservation in
respect to anthropology) is not at all con-
cerned with qualities, and when the investi-
gator deals with them he passes into the field
of applied science, or the arts. Failure to
recognize this distinction leads to much con-
fusion of thought and expression.
One of the milder or less harmful, but at
the same time most conspicuous, manifesta-
tions of this confusion is connected with the
word interesting. Not unfrequently an essay
ostensibly and mainly scientific will contain
the statement that an object, or relation, or
other phenomenon is ‘ interesting,’ the context
indicating that interest is supposed to inhere
in the phenomenon. As a matter of fact,
interest is a mental attitude of the observer,
and the adjective ‘interesting,’ though ap-
plied to the phenomenon, describes only the
observer’s relation to it. There are, of course,
many legitimate uses of the adjective, and
some of these occur in scientific writings.
When an author, for example, declares that
the insect habits he is about to deseribe are
interesting to students of the psychology of
the Bombocoreide, it is clear that he does not
deceive himself by supposing that he has
named a property of the phenomena.
Something similar may be said of important,
valuable, ete., when employed in scientifie de-
scription. In common with novel, pertinent,
significant, and the like, they indicate the rela-
tions of phenomena to the condition of human
knowledge. Just as each observed fact has at
some time, temporarily, the quality of novelty,

so each fact and inference may in some phase
of the progress of knowledge serve to explain
the previously unexplained, and thus have
importance or comparative value. Apart
from such temporary and humanistic rela-
tions, all facts are equally important or equally
unimportant. When, therefore, an author
makes the bald statement that a fact is ‘im-
portant, he ascribes to it a quality and not a
property; and he is self-deceived if he thinks
of the importance as an essential character-
istic.
It conduces to clear thinking as well as
clear writing if one fortifies the use of ‘ in-
teresting’ or ‘important’ by pointing out the
relation which endows the indicated fact with
interest or importance. When that has been
done the need for the adjective often disap-
pears; and if it can not be done, the adjective
is a meaningless platitude.

WASHINGTON, D. C.
SPECIALIZATION, IGNORANCE, AND SOME PROPOSED
PALLIATIVES.
I sre leave to use the columns of Science
to express a few ideas which may strike some
readers as strangely naive, but which have
been incubating in my brain for a term of
years, and must now at length find some mode
of deliverance. I speak as one of that large
class of unfortunates who aspire to contribute
a few small stones to the temple of knowledge,
but who are forced to give so much time to
purely routine work that little is left for better
things. And that precious little remnant of
our time—how do we employ it? Largely in
misspent energy and unproductive eficrts; not
in the quest of knowledge, but of the means
of acquiring knowledge; not in learning facts,
but in learning how to learn! After we have
deducted the time spent in purely mechanical
operations, in developing our technique and in
digesting the ever-growing literature of our
particular little fraction of a sub-science, how
much remains of those brief moments spared
from the struggle for bread? Is it a wonder
that ‘general culture’ suffers, when even our
sister sciences are neglected, or that specializa-
tion so often results in an intellectual isola-

tion, fatal alike to the scientist and the man?
Platitudes?—of course they are! Who has
not deplored these conditions? But we all
resign ourselves to them as inevitable, just as
we do to a social order which tolerates boss
rule, ‘Standard Oil’ and the inheritance of
poverty or riches. Who has not wished to
halt the march of discovery long enough to
allow himself to ‘catch up’? And, seriously,
would it be a misfortune if we should be com-
pelled to pause for a moment in the exploita-
tion of new facts, and properly assimilate the
ones we have? But this is not the burden of
my modest message.
One can not but marvel at the absence of
any adequate bureau of exchange among
specialists in different fields of knowledge. We
have our societies, it is true, where papers are
presented which are oftentimes too technical
even for the limited circle of members—all
fellow specialists in a single science. We
have our journals, congested with contribu-
tions, good, bad and indifferent. But which
one of us can follow all the technical journals
of his own specialty, even though his path
be blazed by international bibliographic cata-
logues? We have our reviews and year-books
and Jahresberichten, in which the topics
treated are apt to gain in technicality in pro-
portion to the degree of abridgment. Various
semi-popular periodicals doubtless do a
splendid work in making accessible some of
the more general conclusions of science, but
their eontents are necessarily fragmentary and
uncoordinated.
In our higher educational institutions we
find specialists engaged in two chief pursuits:
giving instruction to students, and conducting
research. A third possible function of the
faculty seems never to be fully recognized,
namely, mutual enlightenment. Why is there
often such utter isolation between various
departments? Why has there not been estab-
lished any recognized clearing-house for the
exchange of expert knowledge? Much of such
exchange doubtless occurs in a desultory and
haphazard way, through ordinary social inter-
course, so that a man of requisite personal and
social gifts may receive and impart much of
value. And doubtless various public lecture
70 SCIENCE.
courses do something toward meeting this
But why not organize in every uni-
versity an inter-departmental congress, in
which members of the various departments
shall present, in as palatable form as possible,
the problems and discoveries of present interest
in their respective branches of learning? On
the face of things it would seem that such an
arrangement would necessarily result in an
added stimulus and a broader horizon for each
member of the staff, and a greater solidarity
for the whole.
An objector will doubtless be prompt to
point out that the above plan, though plausible
on paper, would, for one reason or another, be
quite impossible in practise.
that no suggestion which offers the least hope
of lessening the baneful effects of over-special-
ization ought lightly to be dismissed. Nor
should I be surprised by the quite different
criticism that my idea utterly lacks novelty,
that it has long since been threshed over by
educational experts, perchance received a fair
trial somewhere. In reply, I could but cite
my own ignorance of these facts as a fine
illustration of the very conditions which I
have deplored.
need.
But there is another idea which I cherish
just as tenderly—one equally chimerical, may-
hap. It is nothing more nor less than the es-
tablishment of a sort of human encyclopedia
as an adjunct to our libraries. How much of
our ignorance is due to the inaccessibility of
knowledge! How many questions we allow to
pass unanswered, rather than grope blindly
The thought
lies near to hand that some one could save us
that trouble-—some one who would not have to
grope. But who? The plain man sends a
query to his daily paper, and receives an
answer which we hope is more trustworthy
than the editorial opinions or news items on
the same sheet. Or he may have the temerity
to write to an expert, who may be good-natured
enough to reply.
amongst unfamiliar volumes!
But where in our educa-
tional system is the man or body of men whose
recognized function it is to answer questicns ?
Teachers we have by the thousand, employed
to impart knowledge in accordance with cer-
tain more or less stereotyped courses of study,
I can only reply _
[N.S. Vou. XXI. No. 524.
but where are the men whose business it is to
tell us just those things for which we happen
to be seeking? The scientific departments of
our government, it is true, give much expert
advice on various matters, in reply to corre-
spondents, and here, indeed, we find our most
instructive models. But their scope is ob-
viously limited.
Suppose that one of our great libraries were
to employ a staff of consulting experts, men of
the rank of college professors, whose duty it
should be to furnish definite bits of informa-
tion in response to legitimate questions, or at
least to guide the seeker on his way. The
cost of maintaining such a library would
doubtless be vastly increased, perhaps doubled
-—I leave that for the professional librarian
to compute. But over against this added cost
could be set the untold hours saved to the
student or the layman, searching in un-
familiar fields, and the vastly greater facility
of the diffusion of. knowledge. My suggestion
might easily be caricatured into the proposal
that the learner should henceforth dispense
with books. Quite otherwise, it is my main
object to enable him to do more reading and
less groping’; to peruse pages of text, instead
of card catalogues and tables of contents; to
economize time, and to minimize the loss of
energy through friction.
Tn the case of a university library, could not
such relations be maintained with the faculty
as to permit of members of the latter body
being called in for expert advice, not sporad-
ically, but as a part of the organic system?
This would throw an additional burden upon
the teaching staff, which would, of course,
need to be increased numerically. But would
not such a function compare favorably in use-
fulness with the teaching of various prescribed
subjects to apathetic learners? To the over-
burdened specialist, such a system would
serve the same end as the plan first proposed,
giving him more ready access to other fields
of thought, and minimizing the evils resulting
from the increasing differentiation of knowl-
edge.
But here again I fear that the experts may
smile at my modest suggestion, either as be-
ing utterly impracticable, or as quite devoid

of novelty or originality. If so, I can but
humbly acknowledge my ignorance, adding
once more that this unhappy condition merely
strengthens my case!

HOW DOES ANOPHELES BITE?
In a recent number of Science Professor
Washburn, in the course of some remarks on
the mosquito exhibit at St. Louis, prepared by
me for the New Jersey State Museum, ques-
tions the accuracy of a figure of Anopheles
in the act of biting. JI do not understand
him to say positively that the figure is inac-
curate, only that it had been his belief .that
the biting position resembled the resting posi-
tion more nearly. The figure in question,
which was a large colored one calculated to
attract the attention of the passers-by, was
intended to duplicate the picture given by
Nuttall and Shipley in their work on Ano-
pheles, its structure and habits. It is really
a very accurate copy of their plate and the
position in my chart is just exactly as pub-
lished. This is an explanation, not a justifi-
cation; if the figure is wrong it should not
have been put on exhibition in that way; but
is it wrong?
When I read Professor Washburn’s note I
tried to recall my own experience with Ano-
pheles. I recall distinctly, watching speci-
mens bite on several occasions, and particu-
larly at Cape May, where Anopheles crucians
was very plentiful in 1903 and bit freely dur-
ing the early morning hours. This habit is
unusual in the genus and attracted my atten-
‘tion, so that I gave the insects every oppor-
tunity to bite; yet, while I can recall dis-
tinetly all the surrounding circumstances, I
do not recall just what position the insect
assumed when biting. I questioned in turn
SCIENCE. V1
every member of the field and office force, and
found that they were equally uncertain in
the matter. All of them had been bitten and
all of them were able to recall specific occa-
sions where they watched the insect bite, yet
none of them would say positively just what
the biting position of the insect really was.
During the summer of 1902 Dr. Herbert
P. Johnson studied Anopheles for me near
Newark, ‘N. J., and kept a number of the in-
sects in confinement, allowing them to bite
from time to time, and of course watching
the operation. I wrote him to the St. Louis
University, where he is at present engaged,
and received an answer as follows: “ While
I have not so distinct a mental picture of the
operation as I would like to possess I am very
confident he [Professor Washburn] is wrong.
The biting attitude he mentions would be a
most extraordinary one, and for this reason:
it is obvious that the mosquito pumping ap-
paratus must penetrate the epidermis before
any blood ean be drawn and the epidermis is
made up of many layers of cells. To thrust
its lancets in obliquely is evidently to encoun-
ter more resistance, do more work, and with
less prospect of suecess than to thrust verti-
eally through the many layers of cells of the
epidermis. If there is an easy way of doing a
thing, nature does not ignore it for a more
difficult way.

still keep it in line with its body, would be
The only way in which Ano-
for the body to assume the vertical position,
which I have never seen it do. It is always
somewhat oblique.”
Mr. Henry L. Viereeck, who spent the entire
summer at Cape May for me and who espe-
cially studied A. crucians, writes: “ In biting
Anopheles crucians stand like A. punctipennis
as shown in Berkeley’s figure 17; that is, with
the body and beak nearly in a straight line
and at an angle somewhat greater than 60°
to the surface. The disposition of the legs
during the act I can not recall exactly, but I
feel quite sure they were very much as in the
figure I have referred to.”
These communications were hardly satis-
factory and we looked up every reference that
was available, only to find that no one who
72 SCIENCE.
has written upon the subject, whose works we
had in hand, spoke definitely on the position
of Anopheles in actually biting. Nuttall and
Shipley deseribe the bending of the proboscis,
and in fact the entire mechanism of biting,
and other authors are almost as detailed as
they; but to the position, no one seems to
refer.
In the hope of getting other information [
wrote to Dr. L. O. Howard, and received this
reply: “I never saw Anopheles bite but once,
and that was in the dusk while I was sitting
on the platform of a railroad station at Fresno,
Cal. My impression was that the beak was
not in the plane of the body; but that the head
was bent downward. Mr. Pratt, when he was
living in Virginia, was frequently bitten by
Anopheles, and tells me that he has a positive
recollection that the head was bent downward
and that the hind legs were curved upward.”
I wish it distinctly understood that this is
not a contribution to knowledge. It is an
illustration of how many men may make ob-
servations in certain lines and absolutely ig-
nore the most obvious points. It is also in-
tended as a suggestion to those who may have
made and recorded direct observations on this
point, to publish their experiences.

SPECIAL ARTICLES.
THE DISCUSSION IN THE BRITISH PARLIAMENT ON
THE METRIC BILL.
Tuere lies before us a reprint from the
Parliamentary Debates in the House of Lords
on February 23, 1904. The order of the day
was the second reading of the bill for the com-
pulsory introduction of metric weights and
measures into the United Kingdom of Great
Britain and Ireland. We will make some ex-
tracts from the discussion which will show the
present conditions over there and which will
interest us because it is universally admitted
that the adoption of the metrie system by one
branch of the English race will secure its
adoption by the other. The reading was
[N.S. Vou. XXI. No. 524.
moved by Lord Belhaven and Stenton, but the
principal advocate of the bill was Lord Kelvin.
In order to show how great change had taken
place in public opinion on the measure in
recent years, as compared with the time not
long ago when the chief argument of the op-
ponents of the bill was that public opinion was
not yet ripe for it, the noble lord presented
petitions from thirty town and city councils,
representing a population of over 8,000,000,
from fifty chambers of commerce, thirty retail
dealers’ associations, forty-three trades unions
representative of 300,000 workers, sixty teach-
ers’ associations, inspectors of weights and
measures in eighty districts and a large num-
ber of individual signatures, bringing the total
number of individuals represented to 333,000.
A nearly equal number additional were prom-
ised within a week, the Liverpool Chamber of
Commerce sending theirs separately by Lord
Avebury, together with several chambers of
agriculture. The difficulties alleged to be
experienced by foreign countries in making
the change were declared non-existent. His
Majesty’s representatives abroad at the time
stated the change was made without much
difficulty; though some countries were more
rapid than others, there never had been any
desire to return to the old system, and the
adoption of metric weights and measures had
assisted the development of trade. Switzer-
land commenced to use the metric system
eighteen months from the passing of the law.
There was no great difficulty found there in
the towns, but it was some time before it was
adopted in remote country places. In Ger-
many it was adopted more quickly than any-
where else. Two years and one month were
allowed, and the interval thus granted was
sufficient to insure the adoption of the new
system in all details; it was an accomplished
fact by the day named. There is no desire
to go back to the old system, and the change
has contributed to a rise of German trade and
commerce, foreign trade deriving much bene-
fit. There are some persons who object from
a dislike to mental effort, and who prefer to
muddle on with the British system described
by the prime minister as ‘ arbitrary, perverse
and utterly irrational.’ To these I reply that

the metric system is bound to be adopted
sooner or later, and that personal inconven-
ience for a few days should not be allowed to
interfere with a measure calculated to promote
the trade and prosperity of the country.
We have had nine years of permission to use
the metric system without thereby rendering
ourselves liable to punishment for a breach of
the law, and experience has proved that the
change from the system that has been so long
in use in this country to a new system can not
be made over the whole country voluntarily.
It is a case for compulsion, and I think the
legislature will be thanked by the country for
having applied compulsion. In Germany,
France and Italy no inconvenience has re-
sulted from the introduction of the metric
system, and there has never been such a thing
as a complaint. The change in Germany oc-
cupied only two years. JI have in my hands
a statement by Sir Wm. Ramsay, in which he
wrote: “I was in Germany during the change
there; it gave no trouble whatever and was
recognized within a week.”
It is interesting to know that the decimal
system, worked out by French philosophers,
originated in England. In a letter dated
November 14, 1783, James Watt laid down a
plan which was in all respects the system
adopted by the French philosophers seven
years later, which the French government sug-
gested to the King of England as a system
that might be adopted by international agree-
ment. James Watt’s objects were to secure
uniformity and to establish a mode of division
which should be convenient as long as decimal
arithmetic lasted, a thing we may consider as
absolutely settled.
I hope this bill will be sent forward with
full pressure to the other house, 333 members
of which have declared themselves in favor of
it and ready to support it.
In introducing the bill, Lord Belhaven and
Stenton recalled some of the testimony given
in the blue book, known as the ‘ Report on
Weights and Measures,’ made to the house of
commons July 1, 1895. That report contained
three recommendations, viz:
(a) That the metrical system of weights and
measures be at once legalized for all purposes.
SCIENCE.
72
(>)
(bo) That after a lapse of two years the
metrical system be rendered compulsory by
act of parliament.
(c) That the metrical system of weights and
measures be taught in all public elementary
schools as a necessary and integral part of
arithmetic, and that decimals be introduced
at an earlier period of the school curriculum
than is the case at present.
Of these recommendations the first was com-
plied with by the permissive act of 1897, which
made the use of the metric system in trade
lawful (it was previously illegal to use it),
and the third was adopted under the educa-
tional code of 1900. The second is in the bill
now before us. An important point in the
history of this subject is, that in August, 1902,
there was a colonial conference attended by
all the premiers of the self-governing colonies,
which passed this resolution: “It is advis-
able to adopt the metric system of weights and
measures for use within the empire, and the
prime ministers urge the government repre-
sented at this conference to give consideration
to the question of its early adoption.” And
since that time the colonies have been pushing
the matter with great earnestness.
The saving of time in education by the use
of the metric system is not only in the teach-
ing of the tables, but the whole system of com-
pound addition, subtraction, multiplication
and division, and the system of computation
called ‘practise.’ Last year inquiries were
made of head masters of schools on this sub-
ject, and 197 sent replies, of which 161 said
the saving would be one year, 30 said it
would be two years, and 6 said that it would
be three years. The senior mathematical
master of Edinburgh high school wrote: “ An
average scholar would save at least a year
and a half, probably two. I conceive it to
be not only a saving of time, but an economy
of mental effort which is incalculable.”
The commercial value of the metric system
has been reiterated by British consuls in
foreign countries for many years. In the
Board of Trade Journal, February 15, 1900,
the British consul at Amsterdam says: “ The
iron and steel manufacturers’ unions of Ger-
many have adopted a uniform system of
74 SCIENCE.
dimensions based on metric weights and meas-
The classifications are making more
and more progress in Germany, not in the
iron trades alone, but in other manufactures.
In the future Germany, and the continent
generally, will have a constantly increasing
advantage over British manufactures in for-
eign countries, unless the metric system be
fully and entirely adopted by Great Britain.
I may mention as an undoubted fact that the
preference which Germany has obtained here
over Great Britain regarding railways, bridges
and other railway material is mainly owing
to the existence of this metric classification.”
Other items in the discussion were that
Russia had directed her iron and steel works
to alter their rolling machinery so as to pro-
duce only rods, rails and sheets on a metric
seale, that 45 per cent. of British exports were
to non-metrie countries and 55 to metric
countries (66 per cent. of United States im-
ports are invoiced in metric measures). At
present Britain has eighty different denomi-
nations represented by 155 different kinds of
weights and measures, which by this bill will
be reduced to thirty denominations repre-
sented by fifty-three different kinds of weights
and measures, or only one third the present
ures.
number.
Vhe bill was read a third time in the house
of lords, May 17, and referred to a select com-
mittee to arrange the practical details neces-
sary to carry it into effect. It was then
passed and sent to the house of commons, and
read the first time. This discussion showed
that there was a very great popular demand
in England for the introduction of the metric
system, more than there is in this country at
the present time. England is a small country,
and the adjacent countries, France, Belgium,
IJolland and all Scandinavia use the metric
system, hence people in general are brought
much more in contact with it than in the
United States, where we only touch the metric
system directly in Mexico, and even this con-
tact is having a decided effect in making the
system familiar to our citizens.
The principal arguments now relied on by
the opponents of the metric system here are
that it has not displaced the old measures in
[N.S. Vou. XXI. No. 524.
countries where it has been legalized, and that
its introduction would be a matter of enormous
expense. Any one who has had personal ex-
perience in foreign travel, or who will take
pains to inquire of any of the thousands of
emigrants that come among us, will soon con-
vince himself that the metric system is the
principal system in actual use in trade and
ecommerce in European countries.
The very large number of working people
who appear in Lord Kelvin’s list as advocates
of the metrie system are drawn to its support
not only by the actual contact with metric-
using nations, but also by the handicap im-
posed by the British system on getting a useful
practical education. This point is increasing
in importanee since the complete change of
both British and American text-books to the
metric system. The absurdity is patent of
requiring the workman to use an old system
different from that in which all knowledge is
gathered by the original workers and com-
muniecated to their students, and of which the
great mass of operatives are ignorant. The
operatives themselves, as soon as they become
fully aware of it, demand the possession of
this key to knowledge and the higher eduea-
tion.
We have heard a great deal in the last three
years about the enormous expense of adopting
the metric system. The great majority of
people who talk about this expense do not
know anything about the actual use of the
metric system, and have not brought one scrap
of testimony that supports their views from
countries that have made the change, while
most of those who advocate the system are
in the actual use of it as teachers, investiga-
tors, ete. The opponents of the system are
in the position of a man who condemns a tool
without ever having used it. Now Lord
Kelvin said in his argument before the lords
that “last year inquiries were made of head
masters of schools, 197 sent replies, of whom
169 said the saving of time by teaching the
metric system would be one year, thirty said
it would be two years and six said it would be
three years. The senior mathematical master
of Edinburgh high school wrote, that in view
of the wearing out of teachers and scholars in
JANUARY 13, 1905.]
obtaining a knowledge of the British system,
the adoption of the metric system would result
in not only a ‘saving of time, but an economy
ot mental effort which is incalculable. ”
Lord Kelvin’s argument applies with even
more force to the United States. The com-
mittee on coinage, weights and measures say
in their report No. 1701, April 21, 1902, made
to the first session of the fifty-seventh con-
gress: “When we consider there are over
15,000,000 school children in the United
States being educated at a public cost of not
less than $200,000,000 per annum, the enormity
of the waste will be appreciated. In the life-
time of a single generation nearly $1,000,000,-
000 and 40,000,000 school years are consumed
in teaching a system that as a whole does not
agree with any other nation in the world, and
which does not offer any advantage whatever
to compensate for its complexity. Surely the
children and teachers of the country are
worthy of quite as much consideration as the
temporary personal and pecuniary interests of
some manufacturers, who have failed to fur-
nish, by either themselves or their representa-
tives, any evidence whatever that the manu-
factures of Germany or Switzerland have or
did suffer any loss whatever by the recent
adoption of the metric system in those coun-
tries. No one in this country has proposed to
affix any penalties legal or otherwise to the use
of the customary system, what we do want,
and are entitled to work for as citizens, is that
the government shall adopt in all its work the
metric system, which is already the interna-
tional system for a majority of the civilized
world.”
The American Machinist, of January 14,
sums up the matter by saying what is true:
“The testimony of men who have kad experi-
ence in all parts of the world with both sys-
tems in the manufacture of machinery is prac-
tically unanimous, that most objections to the
metric system are based upon purely imagin-
ary difficulties, and that the testimony of men
who have not had such experience does not
amount to anything.
We are constantly asked what advantage
will the metric system be to this or that partic-
ular business. The whole community is larger
SCIENCE. 75
than any part of it, and is entitled to first
consideration. We have shown above that one
of the largest and most important activities
in this country, the business of education, will
be enormously benefited, and every other trade
or business will also be benefited, by the in-
creased effectiveness of mental effert in every
direction which is the necessary consequence
of substituting a simple and rational system
for the complex, irregular and barbarous sys-
tem now in vogue.

CURRENT NOTES ON METEOROLOGY.
TEMPERATURES IN THE FREE AIR.
Tue valuable data concerning the tempera-
tures in the free air obtained during the daily
‘soundings’ made at the Prussian Aeronaut-
ical Observatory at Berlin, are discussed by J.
Homma in the Meteorologische Zeitschrift for
October, 1904. The observations considered
are those of the year 1903, and they are
grouped by seasons and by good and bad days,
the temperatures being summarized for differ-
ent altitudes. It is to be noted that the as-
cents were made at different morning hours,
between nine and twelve, and, therefore, the
mean obtained is not to be regarded as ac-
curately representing the conditions during
the twenty-four hours. The vertical tempera-
ture gradients for the four seasons show a
very slow decrease up to 2,000 meters in
winter, and a rapid decrease in spring and
summer. The average rate of temperature
decrease for the year is about 1.3° per 100
meters near the surface, but decreases aloft,
up to about 2,000 meters (0.9°), and then in-
creases with altitude. The mean decrease of
temperature for May, June and July between
the surface and 500 meters is more rapid than
the adiabatic rate of 1.8° in 100 meters.
BAD WEATHER, GOOD ROADS AND FARMERS.
Proressor A. P. Bricuam, in the Bulletin
of the American Geographical Society for De-
cember, emphasizes the need of good roads in
the United States, and points out how great is
the handicap of bad roads to farmers and to
railroads. In this connection, the weather is
an important factor, for when the roads are
76 SCIENCE.
bad, the farmer is greatly restricted in the
times when he can go to market. If high
prices coincide with a period of wet weather
and deep mud, the farmer may lose his oppor-
tunity of getting his crops to market. In
France, cold or stormy days are often used for
hauling to market, but American farmers
usually have to use for hauling the days which
are the best for work on the farm. Railroad
receipts often suffer a serious falling off when
the weather is severe, and when the country
roads are in such condition that farmers can
not haul their produce to the train.

NO SECULAR CHANGE OF CLIMATE IN TRIPOLI.
VICOMTE DE MATHUSIEULX, in an account of
his expedition to Tripoli (Bull. Amer. Geogr.
Soc., December, 1904), states it as his opinion
that there is no reason for supposing any
secular change of climate to have occurred in
that region, although others have taken the
opposite view. The Latin texts and monu-
ments seem, to this writer, to establish the
fact that so far as the atmosphere and soil
are concerned, everything is just as it was in
antiquity. The present condition of the
country is ascribed to the idleness of the
Arabs, who have allowed innumerable wells
to become choked and the vegetation to perish.
“Tn a country so little favored by nature, the
first requisite is a diligent and hard-working
(N.S. Vou. XXI. No. 524.
population. The Romans took several cen-
turies to make the land productive by dam-
ming the ravines and sinking wells in the
wady beds.”
CLIMATIC CHANGE IN THE LAKE CHAD REGION.
Tue evidence from the region between the
Ubangi River and Lake Chad, studied by M.
Aug. Chevalier in 1902-8, is, however, be-
lieved to point towards a progressive desicca-
tion there (La Geographie, May, 1904). M.
Chevalier thinks it probable that a great river
once flowed north across the Sahara to the
Mediterranean, and that Lake Chad was mere-
ly a back water. Vegetable and animal re-
mains indicate an invasion of the Sudan by
the Saharan climate, and Neolithic relics indi-
cate the former presence of prosperous com-
munities. The change is not a regularly
progressive one, for Lake Chad sometimes
spreads beyond its usual bed as a result of
several years of heavy rainfall. Since 1897
the waters have continued to fall. After a
drought in 1902, Lake Fittri dried up in the
following year, and hippopotami which inhab-
ited it went elsewhere.
KITE METEOROLOGY OVER LAKE CONSTANCE.
Dr. HerceEsett has contributed to a recent
number of the Beitrage zur Physik der freien
Atmosphire an account of the observations
made by him with kites on the Lake of Con-
stance, the flights being made from a motor-
boat, loaned by Count Zeppelin, during the
years 1900, 1902 and 1903. The observations
show that inversions of temperature and of
humidity frequently occur in the free air
which are not exhibited by the observations
made at mountain observatories.

THE FIRST OBSERVATIONS WITH ‘BALLONS-SONDES’”
IN AMERICA.
As is known to many readers of ScIENCcE,
there have been despatched in Europe fre-
quently during the past ten years ballons-
sondes, or small balloons carrying only instru-
ments that record automatically the tempera-
ture and pressure of the air, thus enabling the
JANUARY 13, 190v.]
temperatures to be determined at the succes-
sive heights reached, the place and time at
which the balloons fall indicating approxi-
mately the direction and velocity of the upper
currents. The ‘aeronautical concourse’ of the
St. Louis Exposition afforded an opportunity
to undertake these investigations in this coun-
try. Accordingly, the work was taken up by
Mr. A. Lawrence Rotch, director of the Blue
Hill Observatory, in cooperation with Col. J.
A. Ockerson, chief of the Department of Lib-
eral Arts at the Exposition, and a series of
very satisfactory experiments has just been
completed.
The balloons used in the experiments are
the closed rubber balloons devised by Dr. Ass-
mann, director of the Prussian Aeronautical
Observatory. These balloons are inflated with
about 100 cubic feet of hydrogen gas; they
expand in rising until they burst, and then
the attached parachute moderates the fall.
In some eases two balloons, coupled tandem,
were employed, and, as only one balloon bursts,
the other is borne slowly to the ground and
serves to attract attention. The instruments,
which were furnished by M. Teisserene de
Bort, of Paris, record the temperature and
barometric pressure upon a smoked cylinder,
turned by clockwork; and the lightest of them
in its basket weighs about one and one half
pounds. A notice attached to each requests
the finder to pack the instrument carefully in
a box and return either to St. Louis or to Blue
Hill, with promise of a reward for the service.
Owing to delays in obtaining the gas and
apparatus, the experiments were not begun
until the middle of September, during which
month four ascensions took place. All of the
balloons fell within a radius of fifteen miles,
about fifty miles east of St. Louis. Twice the
height of nine or ten miles was attained
where a temperature of 68° F. below zero was
recorded. These experiments were conducted
by Mr. S. P. Fergusson, of the Blue Hill Ob-
servatory staff. Another series of ten ascen-
sions was executed by Mr. H. H. Clayton,
meteorologist at the Blue Hill Observatory,
during the last part of November and the first
days of December, mostly after sunset, in
order to avoid the possible effect of insolation.
SCIENCE. Yi
Fortunately, all these balloons were also re-
covered, though the stronger upper air cur-
rents carried them further from St. Louis,
three of them traveling more than two hun-
dred miles, and two, at least, with a speed
exceeding one hundred miles an hour, the
direction of every balloon being toward the
easterly semi-circle. Ten of the fourteen as-
censions furnished good records, and the re-
duction of the later ones reveals lower tem-
peratures than in September, for example,
72° below zero at the height of seven and
three quarters miles on November 25, and
76° below at six and one quarter miles on the
following day.
The fact that all the balloons were recovered
indicates the excellent topographical situation
of St. Louis for despateching them, and Mr.
Rotch expects to make another series of as-
censions there this month, in order to obtain
the temperatures of the upper air in mid-
winter.

Mr. Francis Darwin has written the follow-
ing letter to the London Times:
‘Greek at Oxford, from a
correspondent in 7'he Times of December 27 occurs
the remark ‘It will be remembered also that
Darwin regretted not having learnt Greek.’
I am at a loss to know on what authority this
statement rests. If Darwin had any regrets on
the subject of Greek it was when he found that
in the two years intervening between leaving
school and going up to Cambridge he had almost
forgotten his classics, and had to begin again an
uncongenial task in order to get a degree.
Darwin says of his education at Shrewsbury
School: “ Nothing could have been worse for
the development of my mind than Dr. Butler’s
school, as it was strictly classical, nothing else
being taught, except a little ancient geography
and history” (‘Life and Letters, I., 31). He
was, in fact, a victim of that *‘ premature speciali-
zation’ which is generally referred to in a some-
what one-sided spirit, and from which the public
schoolboy is not yet freed.
If the name of Charles Darwin is to be brought
into this controversy it must not be used for com-
pulsory Greek, but against it.
In an article on
In 1867 he wrote
to Farrar, ‘I am one of the root and branch men,
and would leave classics to be learnt by those
alone who have sufficient zeal and the high taste
requisite for their appreciation’ (‘ More Letters
of Charles Darwin,’ II., 441).

‘Success to the Expedition,’ said the Liverpool
School had accomplished invaluable work in
the direction of making the West Coast more
healthful and habitable to white men and
natives alike. Mr. James Boyle (American
Consul) pointed out that Liverpool was rapidly
forging to the front as a scientific center, and
both London and Edinburgh would soon have
to look to their laurels. Mr. Walter Long,
M.P., said that Liverpool and the nation at
large owed an incalculable debt to Professor
Boyce. In the history of British colonization
and territorial acquisition the most painful
page was that in which one read of the death,
not of men who had fallen sword in hand
fighting under the flag of their country, but
of those countless thousands whose lives had
been sacrificed, as they now believed quite un-
necessarily, to a deadly and unseen enemy,
which had wrought such terrible ravages in
the past, and which they had every reason to
believe could now be vanquished. This was a
great work, and must result in conquests as
great and lasting as any that science had yet
achieved. Professor Boyce, in responding,
said that the feasibility of Ross’s views on this
subject had now been proved up to the hilt.

FOR CLASSES IN ENGLISH
A NEW AND VALUABLE AID
Outline Studies in College English
By MAUD ELMA KINGSLEY
These Outline Suudies are being called for by English teachers in all parts of the country and
have already been adopted for class use in many influential institutions. They are the result of
years of study by a teacher with a real talent for literature. Able, clear, scholarly, comprehen-
sive, suggestive, they enable the pupil to grasp the subject and retain it in memory, They make
the English class the most interesting of any in the school.

In a technical sense, the Faculties of Law, Medicine,
Philosophy, Political Science, Pure Science, and Applied
Science, taken together constitute the university. These
faculties offer advanced courses of study and investigation,
respectively, in (a) private or municipal law, (6) medicine.
(ce) philosophy, philology and letters, (d) history, economics
and public law, (e) mathematics and natural science, and (/)
applied science. Courses of study under all of these facul-
ties are open to members of the senior class in Columbia
College. Certain courses under the non-professional facul-
ties are open to women who have taken the first degree.
These courses lead, through the Bachelor’s degree, to the
university degrees of Master of Arts and Doctor of Phi-
losophy. The degree of Master of Laws is also conferred
for advanced work in law done under the Faculties of Law
and Political Science together.

A TENTATIVE THEORY OF THERMO-ELEC-—
TRIC ACTION.*
Let the lines (1)—(1) and (2)-(2) in
Fig. 1 be the lines representative respect-
ively, of two metals M, and M, in the or-
dinary thermo-electric diagram. We may,
if we please, think of these metals as copper
-and iron, respectively. The lowest horizon-
tal line is the temperature coordinate and
begins at the absolute zero.

The diagram is so constructed that the
area CC’I'IC is equal to the net thermo-
electromotive force, EH, counterclockwise,
in the circuit indicated by Fig. 2, in which
the left-hand junction is kept at tempera-
ture 7 and the right-hand junction at tem-
perature 7’. We will suppose that EH’ is
expressed in mechanical units, as the

amount of work done, at the expense of
heat, on unit quantity of electricity while
it goes once around the eireuit. Evi-
dently, then, the area CC’l'IC, which rep-
(2)

resents H, represents also the mechanical
equivalent of the net amount of heat con-
sumed by unit quantity of electricity in
one eyele.
The arrow-points in Fig. 1 indicate
merely the direction of the current result-
ing from the net # of the cireuit.
It is consistent with what precedes to
consider the area BCC’B’B as representing
that part of the total, or net, ZH which lies
in the unequally heated M, between 7’ and
T’, the area B’C’l'D’B’, as representing
that part of HE which lies in the junction
M,-M, at T’, ete.; and this interpretation
is sometimes given as a mere statement of
fact. In the course of this paper it will, I
hope, be shown that another view of the
matter is consistent with the known facts
of the case.
As this declaration puts me for the mo-
ment into a somewhat heretical attitude,
let me hasten to say that I hold as strongly
as any one to the proposition that the area
BCC'B’'B represents the amount of heat
absorbed by unit quantity of electricity in
going through the metal M, from the tem-
perature 7 to the temperature 7”, that the
area B’C'l'D'B’ represents the heat ab-
sorbed by unit quantity of eleetricity in
going from M, to M, at temperature 7”,
ete. This proposition is familiar and needs
no proof from me; but I wish to develop
a little one aspect of it which is sometimes
overlooked, an aspect which has a decided
pedagogic value and which is at least sug-
[N.S. Vox. XXI. No. 525.
gestive of the line of thought I wish to fol-
low later.
As we have in Fig. 1 a diagram in which
areas represent heat absorbed, and in which
one of the coordinate axes represents tem-
perature, the other axis must represent
entropy. Let us, therefore, in order to
conform to the common practise in the use
of the temperature-entropy diagram, make
the T axis vertical, and the entropy, or 8S,
axis horizontal, thus getting as the equiva-
lent of Fig. 1 the Fig. 3.

It is to be observed that Fig. 3 is the
obverse of Fig. 1 so that the arrow points,
without any relative change of position in
going from one figure to the other, now
lead clockwise around the area CC’l’IC.
Any one who is familiar with the tem-
perature-entropy diagram of the steam-
boiler-engine cycle, as given and discussed
by Ewing, will see at once interesting
points of resemblance between Fig. 3 and
that diagram. For example, the sloping
line CC’, which indicates one phase of the
Thomson effect, the absorption of heat by
the electric current in passing through the
metal M, from a point at temperature 7
to a point at the highest temperature, 7”,
JANUARY 20, 1905.]
is analogous to the sloping line which in
the steam-boiler-engine diagram indicates
the absorption of heat by the feed water.
from the condenser in mixing with the hot
water in the boiler. The slope of each line
implies that the working agent, electricity
in one ease and water in the other, takes
in the particular quantity of heat repre-
sented by the area under the line at a tem-
perature below the highest of the cycle, and
therefore, does not make the best possible
thermodynamic use of the heat supplied
and of the range of temperature available.
Similarly the inclined line /’J, which indi-
cates that heat is absorbed by the electric
current in passing through the metal M,,
from temperature 7” to the lower tempera-
ture 7’, is analogous to the line of the steam
eyele which indicates the recovery of heat
from the cylinder wall during expansion
after cut-off.
Furthermore, the horizontal lines C’l’
and IC, indicating the absorption or emis-
sion of heat by the electric current in pass-
ing, without change of temperature, from
one metal to the other, are analogous to
those horizontal lines of the steam cycle
which indicate absorption or emission of
heat in the act of evaporation or of con-
densation. To this analogy we shall pres-
ently return.
Let us for the moment occupy ourselves
with a reexamination of the prevailing
opinion as to the relation between the heat
absorption or emission at the junction of
two metals and the difference of potential,
or the electromotive force, at that junction,
that is, between the thermal aspect and the
electrical aspect of the Peltier effect. We
shall find the situation not quite so clear
as it is often supposed to be.
Maxwell* states that the amount of heat
taken up or given out by unit quantity of
electricity in going from one metal to an-
other at any temperature is a measure of
**Electricity and Magnetism,’ § 249.
SCIENCE. 83 *
‘the electromotive contact force at the june-
tion’; and he says that ‘this application
* * * of the dynamical theory of heat to
the determination of a local electromotive
force’ is due to Sir Wm. Thomson.* He
then goes on to declare that—‘‘The elec-
tromotive force at the junction of two
metals, as determined by this method, does
not account for Volta’s electromotive force.
* * * The latter is in general far greater
than that of this article, and is sometimes’
of opposite sign,’’ ete.
But it is a remarkable fact that Thom-
son, years after he had pointed out the
method which Maxwell approves for de-
termining contact electromotive force, came
out (in 1862) with a letter giving a ‘New
Proof of Contact Electricity,’ his famous
‘divided ring’ experiment, in which letter
he says ‘‘For nearly two years I have felt
quite sure that the proper explanation of
voltaic action in the common voltaic ar-
rangement is very nearly Volta’s,’’ ete.
I do not feel called upon to take up the
cudgels for Thomson or for Volta. The
point of immediate interest is that Thom-
son, after proposing the thermodynamic
method of determining contact electro-
motive force, found it possible to hold a
view contradictory to the soundness of this
method. This fact may give the rest of us
courage to question the finality even of
Maxwell’s opinion as to the relation be-
tween electromotive force and heat in the
Peltier effect. I believe, too, that Poin-
earé, in article 292 of his ‘Thermodynam-
ique,’ holds that the opinion supported by
Maxwell may be wrong. Let us see what
we can do with the question thus raised.
By difference of potential, D.., between
two points I shall mean the net amount
of work which must be done because of
the attractions and repulsions of electric
charges (to use the convenient terms of

action at a distance) in carrying unit
quantity of positive electricity from point
1 to point 2.
By electromotive force, Ey, along a
given path from the point 1 to the point 2,
I shall mean
Fy2 = Day + t1.2Ri2,
where 7,, is the current from (1) to (2)
and R,. is the resistance of the chosen
path from (1) to (2).
If either 7 or R is zero,
Fi2= Daa,
which is practically the case when we have
a battery in open cireuit, (1) being one
terminal and (2) the other, or when we
have under consideration two points on
opposite sides of a junction of two metals,
but exceedingly near together, even if a
current is flowing from one to the other.
We have already, looking at Fig. 3, com-
pared the passage of electricity from metal
1 to metal 2 to the evaporation of water
in a boiler. Now in this evaporation work
of two kinds is done upon the water, in-
ternal work and external work. The move-
ment of electricity across a junction against
a difference of potential corresponds to the
external work of evaporation. Is there
accompanying this movement anything cor-
responding to the internal work of evapora-
tion? If so, the heat absorbed by the elec-
tricity in the movement may be as bad a
measure for the difference of potential at
the junction as the latent heat of evapora-
tion would be for the external work of
evaporation.
It is not absurd to imagine that there
may be some change of state of electricity
besides change of potential. It is possible
that we should take account of something
like an attraction between electricity and
the metals with which it is associated.
Helmholtz imagined such an attraction in
order to explain the action of a galvanic
cell, Indeed, we are familiar with the idea
[N.S. Vou. AXI. No. 525.
that attraction or repulsion exerted on the
electric charge which ordinary matter may
bear is communicated to the matter itself.
When the charge on a pith ball is drawn
this way or that, it carries the pith ball
along withit. To be sure, this phenomenon
and others like it may not indicate any
fundamental attraction between ordinary
matter and electricity. Perhaps they can
all be explained by stresses in the dielectric
surrounding or penetrating the ordinary
matter; but whatever the true agencies
may be, they at least simulate attraction
or some physical tie between ordinary mat-
ter and electricity. We may, therefore,
feel free to make speculative use of such
attraction.
Our problem is to find, if we can, by use
of any reasonable hypothesis, an explana-
tion of the way in which heat drives an
electric current around the cireuit of dis-
similar metals unequally heated.
There are two types of mechanical cir-
cuits or cycles operated by heat with which
we are very familiar, the steam-boiler-
engine cycle, in which the circulation may
be practically in a horizontal plane, and
various convection cycles, commonly used
for heating and ventilation, which may be
in vertical planes. In the horizontal cycle
we must have valves. Circulation is se-
cured by heating or cooling a fluid which
is free to expand or to contract on one side,
but not on the other side, the valves being
so contrived as to give the necessary free-
dom and the necessary restriction. In the
convection eyele we do not necessarily make
use of valves. If the heating and cooling
are effected at the right parts of the cir-
cuit, gravity supplies the differential force
necessary to maintain circulation.
How can the metals of our thermo-elec-
tric cireuit take the function of valves or
the function of gravitation and so deter-
mine the flow of electricity at the expense
of heat energy?
JANUARY 20, 1905.]
Let us consider first the case of a thermo-
electric couple in which neither metal has
any Thomson effect, but in which there is
a tendency of positive electricity from (1)
to (2) at each junction. The thermo-elec-
tric force of such a circuit can be accounted
for by assuming that metal 2 attracts posi-
tive electricity more and negative elec-
‘tricity less than metal 1, and that both
these differential attractions increase or .
decrease with change of temperature of
the electricity.
At first glance one is likely to think that
the differential forces here imagined must
increase with rise of temperature, as it may
at first seem that the forces at the hot june-
tion must prevail over the opposing forces
at the cold junction. But this need not
be. The action must be such as to take in
heat at the hot junction and to give out
heat at the cold junction; but this condi- —
tion is perfectly consistent with the pre-
vailing of the attractive forces at the cold
junction.
For, consider the analogous ease of cir-
culation of water in a pipe circuit made
up of two verticals and two horizontals
(see Fig. 5). If heat is applied at the
proper part of one vertical and if heat is
taken away from the proper part of the
other vertical, the water will ascend against
the force of gravity at the heated place and
descend under the pull of gravity at the
eooled place. That is, the attractive force,
upon the differential action of which the
circulation depends, prevails at the place
where heat is taken out from the system.
Another analogous case is that of two
galvanic cells of precisely the same kind,
one cold and the other warm, set to work
in opposition to each other. If the cells
are such that each would grow warm
(aside from the development of resistance
heat within its parts) by its own direct
action, the cooler cell will prevail, and vice
versa.
SCIENCE. 85
So, if the spontaneous action at each
junction of our two metals, if each junc-
tion could have its own way, would be such
as to generate heat at the junction, the
cooler junction will prevail when the two
are opposed, and vice versa.
Now we have rather more reason for
expecting, in a given untried case, that the
- free action of attractive forces will generate
heat than we have for expecting that it
will absorb heat. Consider, for example,
the heat freed as the result of molecular
attractions in the condensation of a vapor.
Accordingly, if we are to account for a
thermo-electrie current, in such a combina-
tion of metals as we have imagined, by
attraction of ordinary matter for elec-
tricity, this attraction varying with the
temperature of the electricity, we are nat-
urally led to the opinion that the colder
junction prevails.
The assumption of such an attraction as
we have here imagined, with its dependence
on the temperature of the electricity and
its independence of the temperature of the
metal, except as the temperature of the
metal determines that of the electricity
within it, is much less violent than it at
first appears. If there is such a phenom-
enon as the expansion of electricity, that is,
a diminution of general volume density of
electricity, with rise of temperature of the
metal containing it, corresponding to the
expansion of air or water in the heated
part of a convection circuit, this is enough
to give just the temperature relation re-
quired. For, the lessened volume density
of the electricity at the hot junction of the
two metals would imply a diminished tend-
ency of the electricity to pass over to the
more strongly attracting metal at that
junction; but just as there is no tendency
of water to flow by gravitation along an
unequally heated pipe, if this pipe is hori-
zontal, so there would be no tendeney for
electricity to flow along an unequally heat-

ed homogeneous metal bar, unless the hot
parts of this bar attracted a given quantity
of electricity more or less strongly than the
vold parts. The two metals in which we
have stipulated that there shall be no
Thomson effect correspond in our thermo-
electric circuit to the horizontal pipes of
our imagined convection system; and for.
the comparison which we are here making
it-is well to go back to the usual disposition .
of the thermo-electrie diagram, in which
unequally heated metals having no Thom-
son effect are represented by horizontal
lines.
Let us now consider a case in which the
Thomson effect does play a part, such a
ease as that illustrated by Figs. 1 and 3.
We ean, apparently, account for the Thom-
son effect in any metal by assuming that
this metal has a greater attraction for elec-
tricity of one sign than for electricity of
the opposite sign, and that the difference
of these attractions is a function of the
temperature of the metal. With this con-
«lition the electricity of one sign at any
part of a homogeneous but unequally heat-
ed metal bar will be subject to a net attrac-
ticn, exerted by the metal, toward a place
cf higher temperature or toward one of
lower temperature, according as the attrac-
tion between the metal and this kind of
electricity increases or decreases with rise
of temperature of the metal; and the other
kind of electricity will be subject to a dif-
ferent, greater or less, net attraction from
the metal; so that a difference of potential
would be set up between the hot and cold
part of the bar, if the bar were left to
itself.
If we take the view that the electromotive
forces which prevail are those at places
where heat is given out, we shall in Fig. 3
have the local electromotive forec, due to
‘the attraction between metal and_ elee-
‘tricity, opposite at every place to the elee-

side at that place; so that the unequally
heated metals and the hot junction will
still conspire against the cold junction;
but, as the direction of the current is
known by experiment to be that which is
indicated by the arrow points in Fig. 3,
we must in this case suppose that the cold
junction prevails over the opposing com-
bination.
Let us now consider the magnitude of
the local electromotive forces. In any case
the net electromotive force of the whole
circuit is expressed, as we agreed at the
beginning, by the area CC’l'IC of Fig. 1
or Fig. 3. But knowledge of the net elec-
tromotive force of the circuit tells us little
or nothing of the magnitude of the indi-
vidual four electromotive forces of the cir-
euit. Ordinary doctrine represents these
by the areas, already mentioned, under the
lines CC’, C'l’, ete., in Fig. 3, down to the
line of absolute zero of temperature, but
as we now undertake to have the electro-
motive force at the cold junction prevail
over the other three, it is evident that we
must look for other areas on the thermo-
electric diagram to represent these local
forces. In this case we find such areas
above the lines CC’, C’'l’, ete., in Fig. 3, or
in Fig. 4, which we will now use in place
JANUARY 20, 1963.]
of Fig. 3. Thus the area Cbb’C’C, ter-
minated above by the temperature lne 7,
characteristic of metal 1, may represent the
thermo-electromotive force directed from
C’ to C in the unequally heated (1).
Similarly the area I’d’dII', terminated
above by the temperature line 7.,, charac-
teristic of metal 2, may represent the
thermo-electromotive force directed from I
to I’ in the unequally heated (2).* The area
0’b'efd'l'C’, terminated above by the broken
line b’efd’, depending on both 7, and T,,
may represent the thermo-electromotive
force directed from I’ to C’ at the hot junc-
tion. Finally the area Cbb’efd’dlC, term-
inated above the broken line bb’efd’d, de-
pending on both 7, and 7.,, may represent
the thermo-electromotive force directed
from I to C at the cold junction. This last,
larger than the sum of the others, which
oppose it, would be the prevailing electro-
motive foree. The net electromotive force
of the cireuit would be, as in Fig. 3, repre-
sented by the area CC’I’IC, and the cur-
rent would run, as before, clockwise with
respect to the boundary of this area.
We have apparently succeeded in ac-
counting for the circulation of the elec-
tricity by means of differential attractions
conditioned by differences of temperature
and in showing that the local electromotive
forces of the thermo-electrie circuit may be
opposite in direction to those which are
commonly supposed to exist. But we have
as yet given no conclusive reason why heat
should go in at one part and out at the
other, and we have not yet made any at-
tempt to show how heat is used up in the
circuit. Our explanation, so far as it has
*T, is apparently the temperature at which the
differential attraction of M, for the two kinds of
electricity becomes zero. A like explanation holds

now gone, utilizes difference of tempera-
ture but does not utilize heat.
If we return to the consideration of our
analogical convection system, we see that,
if we were to put in heat at any point p
only and take out heat at the point p’ only,
these two points being on the same level,
there would be no continued circulation,
as we should presently have the fluid at a
uniform temperature all the way over from
Oo
i
}
p to p’ and at a uniform, though different,
temperature all the way under from p’ to
p. To maintain circulation we must have
the point p, at which heat enters, at a lower
level, and therefore at a higher pressure,
than the level and the pressure of the point
p’, at which heat comes out. The work
and the absorption of heat at expansion
under high pressure would be greater than
the return work and the emission of heat
at the lower pressure, and the difference
between the inflow and the outflow of heat
would be utilized in maintaining
tion against some resistance.
Do we naturally find anything in our
thermo-electrie circuit corresponding to
this heat differential ?
We have already assumed that the elec-
tricity within each metal acts like an ex-
pansible fluid, and it is natural to assume
that the rise of temperature which causes
the expansion of the electricity absorbs
heat. That is, we naturally assume next
that there is a real thermal capacity of
eircula-
88 SCIENCE.
electricity, or of the corpuscles moving
with it, which would come to the same
thing. Moreover, we can hardly avoid
supposing that the attraction which we
have assumed to exist between metal and
electricity holds the electricity within the
metal in a state of pressure; and accord-
ingly we must recognize in the thermal
capacity of the electricity a part accom-
plished against this pressure in the expan-
sion which accompanies rise of tempera-
ture.
Returning, with these additional ideas,
to the examination of a thermo-electric cir-
euit showing no Thomson effect, we find
that we must in such a ease suppose that
in each metal the heat absorbed by the
current of electricity, positive or negative,
which is flowing from cold to warm within
that metal is balanced by the heat given
out by the current of opposite sign, nega-
tive or positive, which is flowing in equal
strength from hot to cold within the same
metal.
But at the junctions the case is different.
At the junction which is the prevailing’
one, across which each kind of electricity
flows from the metal by which its kind is
attracted less to the metal by which its
kind is attracted more, that is, from a
place where the pressure caused by the
attraction is less to a place where the pres-
sure caused by attraction is more, each kind
of electricity will, without change of tem-
perature, suffer contraction of volume in
the transition, and evolution of heat will
result. On the other hand, at the other
junction, where each kind of electricity
moves, without change of temperature,
from a place of high attractive pressure to
a place of low attractive pressure, each
kind will expand in the transit, and ab-
sorption of heat will accompany this ex-
pansion.
Thermodynamic considerations show us
that in such a case as that which we are
LN.S. Vou. XXI. No. 525.
considering, in which there is no Thomson
effect, heat must be taken in at the hot
junction and heat must be given out at
the cold junction. Hence our theory, with
its later assumptions, assumptions suggest-
ed, as others have been, by reflection on
the manner and reason of the working of
an ordinary convection cycle, has led us
clearly to the conclusion that the cold june-
tion should be, in the case considered, the
prevailing junction. But thermodynamic
considerations go further. They require
that the amount of heat, Q’, taken in at the
hot junction at temperature 7’, must bear
to the heat, QY, given out at the cold junc-
tion at temperature 7, such a relation that
Can we without a straining extension of
our assumptions meet this condition? Ap-
parently we can do so by supposing that
electricity in its state of compression with-
in each metal obeys the law of a perfect
gas. At the hot junction we have the posi-
tive electricity going, at constant tempera-
ture 7’, from the attractive pressure p to
the attractive pressure p — dp, with con-
sequent expansion, work of expansion, W’,
and absorption of heat equivalent to this
amount of work. At the cold junction we
have the positive electricity going, at con-
stant temperature 7, from the attractive
pressure p — dp to the attractive pressure
p, with consequent compression, work of
compression, W, and evolution of heat
equivalent to this amount of work. From
the gas law, pv = KT, we have, when T
is constant,
padv = — dp = —
This gives us, since p and dp are the same
at the hot junction as at the cold junction,

The production of absorption of heat
within a single unequally heated metal, the
calorimetric aspect of the Thomson effect,
is, apparently, easily accounted for without
additional assumptions. Thus, according
to the theory already stated, the line CC’
in Fig. 4 represents a case in which the
attractive pressure of the positive elec-
tricity is greater at the cold end than at
the warm end, while the attractive pres-
sure of the negative electricity is greater
at the warm end than at the cold end, of
metal 1. According, positive electricity
moving from the eold end to the warm end
of this metal will expand more, and there-
fore absorb more heat, than the mere rise
of temperature requires, while the negative
electricity in moving from hot to cold with-
in the same metal will contract less, and
therefore give out less heat, than the mere
fall of temperature requires. That is, to
use the conventional mode of expression,
the current absorbs heat where it flows
from cold to hot in metal 1. For the line
II’ and the metal 2 the case is wice versa.
The conception of electricity, each kind
of electricity, as acting within a metal like
a perfect gas seems very revolutionary to
one who has been strongly impressed by
Maxwell’s discussion of the analogy which
the behavior of electricity in Faraday’s
‘ice-pail’ experiment presents to the be-
havior of an ‘incompressible fluid,’ though
Maxwell in pointing out this analogy warns
us against being too much influenced by it.
The ice-pail experiment, however, as I
understand it, proves merely the difficulty
in putting an appreciable excess of either
kind of electricity into a given space, a
difficulty which still exists after all the
assumptions of this paper are made. Con-
sider, for example, the difficulty of putting
any considerable excess of positive or of
negative ions into an electrolyte. Indeed,
the idea of the electric current within a
solid as consisting of two oppositely mov-
SCIENCE. 89
ing perfect gases is so like the familiar and
commonly accepted idea of the current in
an electrolyte, where we apparently have
two oppositely moving bodies of ions, each
body obeying the gas law in its osmotic
pressure, that, instead of being troubled
by the heretical character of this view of
the current in a solid, I am somewhat con-
cerned lest I am failing to give due credit
to some one who has already proposed it.
Of course, Drude in his electron theory
does apply the gas laws in some particulars
to the electrons within metals, and I can
not be sure that he has not anticipated me
in much that is given in this paper, though
I did not, so far as I am aware, get from
him any of the main features of the theory
here proposed.
The question naturally arises, Why not
determine the direction and magnitude of
the local electromotive forces of the thermo-
electric circuit, and so get a decisive trial
of the case between the ordinary and the
proposed view of thermo-electrie action?
The reply is that physicists have been try-
ing for more than a hundred years to get
a satisfactory determination of a single
one of these local forces, the one measured
by the true contact difference of potential
between any two metals, and have, appa-
rently, not yet succeeded in the attempt.
It is the old question of the Volta effect.
Some months ago I was of the opinion that
Mr. John Brown, F.R.S., of Belfast, had
found a way of getting rid of the dis-
turbing effect of the medium surrounding
the two metals, zine and copper in his ease,
by heating them for several hours in a cer-
tain kind of oil. Considerable recent ex-
perience with various kinds of oil at the
Harvard Physical Laboratory has led me
quite unwillingly to the conclusion that the
kind of treatment to which Mr. Brown
subjects his metal plates may substitute
for the disturbing surface condition ac-
quired in air an equally baffling surface
90 SCIENCE.
condition produced by the action of the oil.
An attempt to measure directly the dif-
ference of potential between the two ends
of an isolated unequally heated bar of
metal would, apparently, encounter ob-
stacles quite as great as those which have
thus far proven unsurmountable in the
ease of attempts to measure directly the
eontact difference of potential between
metals. The outlook is, therefore, not
bright for any immediate and final answer,
on experimental grounds, to this question
of the direction and magnitude of the local
electromotive forces with which we have
been dealing.
I wish to add one afterthought. If elec-
tricity flows like a perfect gas through a
homogeneous solid conductor of uniform
cross-section, its velocity at any given cross-
section of the conductor must be, approxi-
mately at least, proportional to the abso-
lute temperature of this cross-section. Now
the ordinary law of resistance in the case
of a fluid moving through small passages
is this: Resistance is proportional to the
velocity. Accordingly, we are led to the
conclusion that the resistance encountered
by our electric stream should be propor-
tional to its velocity, that is, other things
being equal, proportional to the absolute
temperature at the part of the conductor
considered. Now we know that in pure
metals this is the general law of resistance,
and the fact that this law finds an explana-
tion in a conception of the electric current
formed without any reference to electrical
resistance adds considerable weight to the
argument in favor of that conception.

THE ALAMOGORDO DESERT.*
THE desert of southern

106th meridian, west, and approximately
between thirty-two and thirty-four, north.
It is bounded on the north by the Oseuro
range of mountains, on the east by the
Sacramentos, on the south by the Jarillas
and the Organ mountains, on the west by
the San Andreas. As here defined, there-
fore, the desert is of comparatively limited
area, one hundred or one hundred and
twenty-five miles from north to south, and
perhaps thirty-five to fifty from east to
west; a very convenient little desert, easily
manageable, one might suppose, for any
naturalist, who, with inborn love of ad-
venture, starts out in search of the wilder-
ness to find scenes and pastures new.
A year ago in this presence, it may be
recalled, the present speaker, by aid of
photographie illustrations, attempted to
sketch the relations obtaining, as would
appear, between the geology of the desert
and its flora; in the present paper it is
intended briefly to resume the earlier argu-
ment with such added reflections as may
be suggested by present conditions and by
recent renewed acquaintance with the prob-
lem.
The desert of Alamogordo or Tularosa
is a great plain, not unmarked, however,
by singular topographic inequalities later
on to be deseribed. Only the most casual
geologic examination is sufficient to show
that the plain floor corresponds strati-
graphically with the beds in some places
exposed at or near the tops of the sur-
rounding mountains, in any case far up
their flanks. On the east especially lime-
stones of carboniferous age rise sheer some
1,000 feet or more straight up from the
desert floor, and are again capped by other
strata only at length, perhaps 1,000 feet
higher, surmounted by materials corre-
spondent with those in the level of the
plain.
On the west the same thing is true; but
more emphasized still is the difference in

level between segments of corresponding
strata. Here the weird Organ mountains
break the horizon by upthrust spires and
pinnacles of granite which to some early
voyageur crossing these dusty plains sug-
gested the pipes and architecture of some
far-off organ, and the mountains were so
named; but upturned granite means that
the sedimentary rocks are here further up-
lifted still than on the eastern side, so that
we quickly find ourselves in presence of
vast parallel faults and our desert hes thus
between their giant walls. It is as if half
the region between this city and New York
should suddenly sink two or three thou-
sand feet, or what is the same thing, it is as
if the several thousand feet of difference in
level were brought about by the depression
of the included area, and the simultaneous
elevation of the sides. At any rate, the
desert plain of the Alamogordo or Tularosa
sands is simply the upper surface of a
migantic block of the earth’s crust that
sank some time subsequent to the deposi-
tion of the Jura-Trias and the earlier
eretaceous strata of this western world.
These strata include, as we know, the
famous ‘red beds’ which tinge the moun-
tains of half the continent, the red beds
with all their gypsums, marls and salts of
every description. Accordingly, as a re-
sult of this faulting, our desert has for its
foundation everywhere great fields of gyp-
sum, often for long distances wide-exposed,
sometimes thinly veiled by loosened sand,
sometimes deep buried by vast deposits of
wine-red marls and clays, or covered anon
by the products of erosion, whether by
water or by wind. The waters from the
mountain snows have brought their débris;
the winds of the desert have come with
their burden, but nowhere has such trans-
portation traversed the desert borders, at
least in recent times; there are to-day no
excurrent nor percurrent streams; the

winds die along the mountain walls and
the waters sink in the desiccated sands,
But this is not all. This great sunken
block of earth’s crust seems itself to have
been cracked again and again; there are
secondary faults, and along the line of one
of these thinner or weaker places the sub-
terranean energies of the world have some
time found emergence. Floods of lava
welled up in the midst of the desert, and
fountains of fire streamed along the
eround, following existent topography for
miles and miles, now narrowing to dimen-
sions measured by rods between low ranges
of hills, now widening for miles across the
broader valleys, only to lie at last a vast
field of blackened cinder, slowly disin-
tegrated by the desert storms. This is one
of the most peculiar topographic features
of the whole desert. As things terrestrial
go, this is a recent phenomenon. The age
of the lava may be measured by centuries,
a few thousand years, it would seem, at
most. The surface over which it poured
was a friable, marly soil. As the floods
cooled, the mass cracked and gaped in every
direction. Rains descending upon the sur-
face sank to the ground below and shaped
for themselves channels. The lava so un-
dermined has fallen into a tumbled ruin
of weirdness and confusion, indescribable,
impassable.
The lava constitutes one of the features
of this remarkable desert; there is yet an-
other. Along the western border, partly
uncovered by erosion, partly by the west-
ern winds, great bodies of gypsum lie ex-
posed. As this slowly disintegrates the
wind gathers the particles set free and
bears them eastward, the famous white
sands, covering township after township
with drifted mineral white as snow. Vast
windrows shifting slowly with every storm,
and forever reinforced by the unceasing
contributions of the west, mark the land-
scape over several hundred square miles,

unique, intact, forever changing, yet the
same forever.
Added to these peculiar and special topo-
graphic details of this surprising desert
we have, of course, those less noteworthy,
the common every-day features of desert
make-up: we have mountain slope, rocky
fields and hillsides, eroded valleys, marshy
sinks, where lose themselves the vanishing
torrential streams; wide plains of marly
clay, belts of sand-dunes, red sands, yellow
sands, also shifting and moving, but, better
subservient to the vegetation of the region,
these present simply vast fields of low
hills or hummocks ten to twenty feet in
height, separated on every side by tortuous
valleys, winding in labyrinthine fashion,
wind-swept, hard and bare.
One other topographie feature must yet
be added to complete our picture. The
forces of erosion even along the mountain
walls have kept pace fairly well, at least,
with the changes in level. Great canons
break back even through the hard, eneri-
nitic limestones, dividing again and again
where the waters have carved the rugged
pathway by which the explorer may reach
the mountain summit. The result of this
erosion forms a wide talus around the
desert, spreading great fan-shaped deposits
at the mouth of the cafon, where immense
blocks and boulders choke the exit, suc-
ceeded by ever smaller rocks and pebbles
farther out, until at length only the finest
silt is swept along from the widened mar-
gin far across the almost perfectly level
plain.
Now it is evidently needless to say to
every wisest man in an ecologically minded
such as this, that every one
of these peculiar topographic features,
whether special or not, will display its
own peculiar flora. True, this is not
always the ease; this desert must be studied
in its entirety, and it will require months
of patient research to even sketch its far-

reaching problems. As a whole the fiora
may be said to be that of our western arid
regions generally, and yet, after all, it is
not just like that of any other region, north,
south, east or west; not that it has peculiar
species, perhaps, but that it has its own
particular groups of species.
Two factors, and two alone, as it seems to
me, determine the phytology of this desert;
the one, difference in the constitution of
the soil, referable to its geologic history;
the other difference in level, referable to
the same initiative. Thus there is a pecul-
iar flora on the sands whether white or
red; another on the silted plains less liable
to transportation by the wind; another
where the salts emerge, whether in briny
springs and fountains or as_crystals whit-
ening the surface of the ground; another
for the mountain shelves; and still another
for their far-off summits.
The El Paso Northeastern Railway passes
the desert on its eastern side. There are
two stations on the line where for several
miles in every direction the surface is a
red-brown sand. One of these stations has
been by the railroad people appropriately
named Desert, the other is Esecondida. The
level of the two stations is the same, 4,000
feet, and the flora is identical, although
the points are thirty miles apart. Each,
however, is by itself unique and entirely
separate from the other. The dominant
species is Yucca radiosa, so much so that
these points are called the yucea desert.
Of course, the almost ubiquitous mesquite
is there and Atriplex canescens and Arte-
misia —— sp.? There are other species, to
be sure, such as forms of Chrysothamnus
and Ephedra, but the plants first named
give to the plain its character as far as
vegetation goes, and in topography as well;
they not only thrive here and come to
abundant flower and fruit, but they hold
these peculiar sands otherwise driven about
the world by desert winds.

Now it is a remarkable fact that the
white sands, thirty or forty miles off to the
northeast, exhibit an almost identical flora.
The student hastens across the intervening
desert to meet that shining wall, expecting
to find all things new; but, behald, the
white sands are sands first of all rather
than anything else. Whatever their chem-
istry, and they have their peculiar prob-
lem for the chemist, only a vegetation that
can endure a moving, shifting terrene can
flourish here. The white sands form, ac-
cordingly, part of the yueca desert. Their
relation to vegetation is almost purely
physical, but they exhibit some peculiar-

THE NATIONAL BUREAU OF STANDARDS
AND ITS RELATION TO SCIENTIFIC
AND TECHNICAL LABORATORIES.*
THE dedication of a large and well-ap-
pointed building to be devoted exclusively
to instruction and research in physics is a
notable event in the history of a college.
In this instance it is the realization of a
hope long cherished by many, and by none
more than by the present speaker. That so
splendid a building has been deemed neces-
sary for, the work to be done in physics
suggests two things. First, the high stand-
ard which Wesleyan is setting for herself
in this as in other departments of work,
and, second, the rapid development which
has oceurred in recent years in physics,
rendering imperative an equipment for ex-
perimental work of an entirely different
order of magnitude from that thought suf-
ficient a generation ago. So great has been
the demand for the best instruments and
standards to be used in experimental work,
both in pure and in applied physies, that
the government has been led to establish at
Washington a national laboratory, one of
whose functions is to cooperate with scien-
tifie and technical institutions and manu-
facturers in the work of improving instru-
ments and standards and developing meth-
ods of measurement. It, therefore, seems
not inappropriate that something be said
on this oceasion concerning this work of
the national government, so recently in-

augurated as not to be generally known.
The bureau of standards was established
by act of congress in response to a de-
mand for such an institution on the part
of many scientists, engineers, manufac-
turers and representatives of the national
government. The high order of accu-
racy required in modern engineering prac-
tise and in scientific research made it more
than ever. necessary that manufacturers
of scientific and engineering instruments
should possess correct standards of length,
mass and volume, as well as electrical, op-
tical and thermometrie standards, and be
able to have them reverified from time to
time. It was also important that any one
engaged in scientific or engineering work
could have his instruments and standards
tested whenever, necessary. The office of
weights and measures, at Washington, had
been equipped to do some of the work re-
quired in the verification of length, mass
and volume for many years, but it was
uecessary to send electrical standards,
thermometers and pyrometers and many
other kinds of apparatus to Europe to be
tested when results of the highest accuracy
were desired. As this was both expensive
and time consuming the consequence was
that only infrequently were these more ac-
curate tests obtained. The United States
held a creditable position among the na-
tions of the earth in physical science, and
had some of the best physical laboratories
in the world; it was leading the world in
the manufacture of electrical machinery
and some kinds of electrical instruments.
To’ be obliged to ask the German imperial
or other foreign laboratories to do our
testing for us, because we lacked a well-
equipped national laboratory for doing such
work, was clearly a situation that ought to
be corrected, and congress acted promptly
when the importance of the matter was
brought to its attention. Appropriations
were made for laboratory buildings and

equipment and for a director and a small
scientific staff, and the bureau began its
work July 1, 1901. President McKinley
appointed as director Professor S. W.
Stratton, of Chicago University, to whom
more than to any one else is due the credit
for, the establishment and the success of
the bureau. A careful study of the Physi-
kalisch Technische Reichsanstalt and of
other European laboratories was made in
connection with the designing of the labo-
ratory buildings and the selection of the
equipment, and many valuable suggestions
were derived therefrom. The laboratories
have, however, been constructed after Am-
erican rather than European models, al-
though in their equipment it has been
found necessary to draw very heavily upon
European instrument makers.
The bureau began its work in temporary
quarters and has been developing methods,
building and acquiring apparatus and do-
ing testing for the government and the
public while the laboratory buildings have
been under construction. The larger of
the two buildings was only recently com-
pleted and the bureau is just now moving
into it, the first building having been occu-
pied nearly a year ago. We now find our-
selves, about three and a half years from
the organization of the bureau, in posses-
sion of buildings and equipment costing
about $600,000, with a personnel carefully
selected through the civil service and num-
bering altogether seventy-one, maintained
by annual appropriations amounting to
nearly $200,000, and, judged by the magni-
tude and importance of the output of test-
ing and investigation, ranking second only
to the great German Reichsanstalt among
the government laboratories of the world
doing this kind of work.
After this brief epitome of the history
of the bureau let me state more particu-
larly something of its work and of its rela-

tion to the scientific and technical labora-
tories of the country.
The work of the bureau may be briefly
specified under three separate heads as
follows:
1. To acquire and preserve standards of
measure and to certify copies of the same,
and to test and investigate measuring in-
struments and to determine the properties
of materials.
2. To conduct researches and to investi-
gate and develop methods of measurement ;
to improve instruments and apparatus for
physical measurements and to devise new
apparatus, especially for use in testing and
in precise measurements.
3. To distribute information regarding
instruments and standards to manufactur-
ers, state and city sealers of weights and
measures, scientific and technical labora-
tories, and to any and every one applying
for such information.
These three functions of the bureau are
closely interdependent. To acquire a
standard in some cases involves an elab-
orate investigation and the independent
determination of the value of the stand-
ard; and to preserve it may involve subse-
quent redeterminations of its value to
ascertain whether any change has occurred.
A new kind of test often involves the in-
vestigation of methods of measurement, or
the determination of new standards or the
construction of a new instrument. Thus
research and testing are intimately con-
nected in most of the work of the bureau.
The distribution of information, the
third function of the bureau, is accom-
plished through correspondence and the
cireulars and bulletins issued by the bu-
reau, and also by the personal visits of
people seeking such information.
The three fundamental standards of
measure are those of length, mass and time.
The oldest of these is the unit of time, the
second. This ancient unit has successfully

withstood every attempt to replace it by a
decimal submultiple of the day. The earth
itself is our fundamental timepiece, every
revolution upon its axis counting off 86,400
sidereal seconds, from which we immedi-
ately derive our standard second. No
clock is so perfect a timepiece as the earth
and all the standard clocks in the world
are corrected by it. What the astronomer
does in determining the time by astro-
nomical observations, is to read off the
time of day or night by means of a tele-
scope on the starry face of the celestial
clock. The telescope corresponds to the
hour hand of a 24-hour dial (there is no
minute hand), and the stars mark the sub-
divisions of the dial. The best made clocks
of human invention go fast or slow by at
least some fraction of a second each day,
but there is no proof to show that the ter-
restrial clock deviates by so much in a
thousand years. Thus the unit of time is
a natural unit, easily obtained direct from
nature and universally employed the world
over.
The Bureau of Standards does not in-
tend to make independent time observa-
tions, but will correct its standard clocks
from the observations made at the neigh-
boring Naval Observatory.
The unit of length has a very different
history. The foot has been the most wide-
ly used measure of length, both in ancient
and in modern times. It was derived, as
the name suggests, from the length of the
human foot and is thus a natural unit like
the second; but, owing to the multiplicity
of human feet and their varying dimen-
sions, this unit has varied greatly in differ-
ent countries and in different ages, its
leneth ranging all the way from the an-
cient Welsh foot of nine inches to the Pied-
mont foot of twenty inches. In modern
times it has varied from the Spanish foot
of less than eleven inches to the Venice foot
of over thirteen inches, almost every coun-
164
try using a foot of different length. The
confusion resulting from this lack of uni-
formity prompted the French in 1799 to
adopt a new unit of length, and remember-
ing how surely and elegantly the unit of
time is fixed by the rotation of the earth,
they sought to make the meter, the new
standard of length, permanent and inflex-
ible by basing it upon the dimensions of
the earth. The meter was chosen to be one
ten-millionth part of the distance from
the equator to the pole of the earth at a
particular meridian, and was fixed in con-
erete form as the length of a platinum bar,
which has been carefully preserved in
Paris. Subsequent and more accurate
measurements have given a slightly differ-
ent value for the circumference of the
earth, so that the meter is known not to be,
as originally intended, just one ten-mill-
ionth of a particular quadrant of the
earth. The meter has, however, not
been changed, its value being fixed by the
length of the platinum standard and not
by the earth. Thus the platinum bar has
become the primary standard of length,
instead of a secondary standard as was
originally intended. This is a happy re-
sult, for the difficulties of comparing a
meter with the dimensions of the earth is
too great to make the dimensions of the
earth of any value as a standard of length.
The original standard meter has been
reproduced many times in platinum and
iridio-platinum, and many of the civilized
nations of the earth possess such duplicates.
We have two of them at the bureau of
standards in Washington, one of which was
recently taken to Paris by Mr. Fischer, and
recompared with the standards of the inter-
national bureau. The results showed al-
most perfect agreement with the compari-
son made fifteen years previously, the dif-
ference, if any, being not greater than
about 0.5 of a micron, that is, 1/50,000
inch. This is one part in 2,000,000 of the

(N.S. Vor. XXT. No. 527.
length of the bar and represents about the
limit of accuracy obtainable in comparisons
of this nature, although the computed
probable error of the observations was only
.02 of one micron, or less than a millionth
of an inch.
The third fundamental unit, that of mass,
has likewise varied in different countries
and in different ages. The most widely
used unit was the pound, and before the
metric system came into use there were hun-
dreds of different pounds in use in Europe,
differing from country to country and from
province to province, and varying also ac-
cording to the commodity to be measured.
The ancient Roman pound was equivalent
to a little less than twelve of our avoirdu-
pois ounces, and from it were derived the
various Italian pounds, varying in value
from the Venice light pound, equivalent
to about eleven of our avoirdupois ounces, —
and the Naples silk-pound and the Milan
light pound of about twelve ounces to the
Piedmont pound of about thirteen ounces
and the Venice heavy pound of about sev-
enteen ounces. There were silk pounds,
and chocolate pounds, and table pounds,
and goldsmith pounds and _ medicinal
pounds; there were lght pounds, and
heavy pounds, and half-heavy pounds and
extra-heavy pounds. There were pounds
of 12, 14, 15, 16, 17, 18, 20, 21, 22, 24, 2ay
30 and 36 ounces, and the ounces had vary-
ing values in different countries and in
different provinces of the same country.
To remedy this distressing confusion the
French, in 1799, at the same time the meter
was chosen, adopted the kilogram as the
unit of mass, fixing it concretely in a cylin-
drical mass of platinum, which was intend-
ed to be equal to the mass of a eubie deci-
meter of water at the temperature of its
maximum density. This, lke the meter,
was designed to be a natural unit that
could be derived originally at any subse-
quent time and in any country. But, as
Fresruary 3, 1905.]
in the ease of the meter, later determina-
tions showed that the kilogram was not
exactly equal to the mass of a cubie deci-
meter of water as was intended, and hence
the platinum secondary standard was
adopted as a primary standard of mass and
no further attempt made to make it a nat-
ural unit. All other countries using the
metric system use carefully constructed
copies of this original kilogram as their
standards cf mass. ‘The process of weigh-
ing is even more accurate than the com-
parison of lengths, so that the standard
kilograms of the various countries of the
world are practically perfect duplicates of
the original and of each other.
In 1875 a conference of the representa-
tives of seventeen nations was held in Paris
and a permanent international bureau of
weights and measures was established and
is still maintained. It is located at Sévres,
near Paris, and is supported jointly by the
participating nations. Its duties are to
eare for the fundamental standards of
length and mass, to furnish accurately ad-
justed copies of the same, and to compare
standards which may be returned from
time to time. Some other testing is done,
including the calibration of thermometers.
The work is of the highest order of accu-
racy and leaves little to be desired so far
as standards of length and mass are con-
cerned. The metric system has been adopt-
ed by nearly all the civilized nations of
the world, excepting Great Britain and her
colonies and the United States, and is uni-
versally used throughout the world for sci-
entific purposes. The electrical units are
all based on the metric system and hence
electrical engineers employ the metric sys-
tem almost exclusively, even in this coun-
try. The gain to science and commerce due
to the adoption of the metric system can
searcely be overestimated and it is to be
hoped that it will scon be adopted by the
English-speaking countries of the world.

The avoirdupois standard for the United
States was defined in 1830 as 7000/5760
of the Troy standard pound of the mint,
which in turn was a copy of the British
Troy pound, derived from the standard of
Queen Elizabeth made in 1588. The latter
was derived from the standard of Edward
IIl., and this is said to have come from
the city of Troyes, France, hence the name,
Troy pound. The metrie system was legal-
ized in the United States in 1866, and the
meter was declared to be equivalent to
39.37 inches and the kilogram to 2.204
pounds. The international bureau began
its work in 1879. The iridio-platinum
prototypes cf the metric standards were
received in this country in 1889. These
were so much superior as standards to the
brass standard pound and _ the
yard, that in 1893 the metric standards
were adopted as fundamental standards by
the United States and the pound and yard
were defined in terms of them. Thus the
metrie system is not only legalized in this
country, but our fundamental standards
are the meter and kilogram and all our
weights and measures are derived from
these metric standards using the legal
equivalents.
Few people, perhaps, realize how need-
lessly complex our system of weights and
measures really is. Instead of a single
unit of weight and of length with multiples
and submultiples having ratios of ten, and
a unit of volume simply related to the unit
of length, as is the case in the metric sys-
tem, we have a multiplicity of units and all
kinds of odd ratios for the multiples and
submultiples. I beg your indulgence for
a moment while I remind you of some of
the absurdities of our system. But first
recall how much simpler and more con-
venient our decimal coinage is than the
English coinage. Nothing could be simpler
than the expression of values in dollars
and cents; the use of pounds, shillings and
bronze
166
pence, to say nothing of guineas, crowns
and farthings with their odd ratios, being
cumbersome in But our
weights and measures are far more cum-
bersome and complicated than the English
coinage. We weigh most merchandise by
avoirdupois weight, gold and silver by troy
weight, medicines by apothecaries’ weight,
diamonds by diamond carat weight. We
have dry quarts and liquid quarts, long
tons and short tons, and a hundredweight
is not 100, but 112 pounds. Coal is usually
purchased at wholesale by the long ton and
retailed by the short ton. A bushel some-
times means 2,150.4 cubic inches and some-
times it means a certain number of pounds
weight of a commodity. The American
bushel is derived. from the old English
Winchester bushel, but the legal English
bushel of the present day is larger by 69
cubie inches. On the contrary, the Eng-
lish gallon is much larger than the Amer-
ican gallon, the difference amounting to
about 20 per cent. We measure wood by
the cord, stone by the perch, earth by the
cubie yard. Moreover, among the different
states of the union are considerable differ-
ences in custom and in legal equivalents.
We are, of course, much better off than the
countries of Europe were a century ago,
but the difference is all too small.
Our medieval system of weights and
measures is, however, too deeply rooted to
be easily displaced. But the metric system
is being used in this country more than is
generally realized and our rapidly grow-
ing foreign trade is bringing it more than
ever to the attention of merchants and
manufacturers. In England a strong ef-
fort is being made to adopt the metric
system, with the hope that ultimately a
decimal system of currency may also be
adopted. The English colonies are even
more progressive than the mother country,
and strong influences are at work to secure
the decimal system throughout the British
comparison.

empire. It will be greatly to the advan-
tage of the United States to keep abreast
of this movement, and not to be the last
among the civilized nations of the world
to throw off the ineubus of an incoherent
system of weights and measures, whose
chief claim lies in the fact that it is in
general use.
The testing of lengths and masses con-
stitutes one of the most important branches
of the work of the bureau. As I have said,
this work has been done by the government
for many years, but the facilities for the
work are being immensely improved by
the bureau so as to extend the range and
imerease the accuracy of the work. The
new laboratories will contain many new
balances and comparators and every pre-
caution is being taken to secure the most
favorable conditions possible for precision
work. When the installation is completed
it will probably be the best of the kind in
the world.
I have said that the three fundamental
units of measure are those of length, mass
and time, or the meter, kilogram and sec-
ond. From these are systematically de-
rived various other units, all forming what
is often called the centimeter-gram-second
system, or, more briefly, the ¢.g.s. system.
It is not my purpose to enumerate the vari-
ous derived units which are employed in
scientific and technical work, but rather to
describe briefly some of those employed in
the testing and research work of the bu-
reau. And first let me speak of the work
in heat and thermometry. The testing of
thermometers is one of the most important
branches of the work of the bureau. This
work is under the charge of Dr. Chas. W.
Waidner, who is personally known to some
of you. Dr. Waidner and his assistants
have devoted a great deal of effort to the
acquisition of reliable standard thermom-
eters and to the investigation of instru-
ments and methods. In this they have
Fepruary 3, 1905.]
availed themselves of the results of the
magnificent work that has been done in
this field in Europe, more especially at the
Bureau Internationale and the Reichsan-
stalt, and by the thermometer makers of
France and Germany. For our present
purpose thermometers may be conveniently
grouped as follows: (1) Precision mereury
thermometers, to be used as standards or
for scientific purposes. They are calib-
rated very elaborately and are capable of
high accuracy. (2) Ordinary mercury
thermometers and clinical thermometers.
We test clinical thermometers by the thou-
sand and we hope before long that they
will come to us by the tens of thousands.
Clinical thermometers often change if grad-
uated new, and hence they ought always to
be aged, tested and certified to insure their
eecuracy. (3) High temperature mercury
thermometers of hard glass, with nitrogen
under pressure above the mercury column,
reading up to 550° C. (or about 1000° F.).
(4) Platinum resistance thermometers,
thermocouples and other forms of pyrom-
eters suitable for measuring furnace tem-
peratures up to 1600° C. (about 2900° F.).
Such instruments are used in many manu-
facturing processes, as well as in research
problems and hence are found both in
scientific and in technical laboratories. (5)
Optical pyrometers for measuring the tem-
peratures of the hottest furnaces and, ap-
proximately, even the temperature of the
electric are, the highest temperature attain-
able by any known means, namely, about
3950° C. (or 7150° F.). An investigation
on this subject at the bureau has recently
been published by Drs. Waidner and Bur-
gess. (6) Low temperature thermometers,
for temperatures below the freezing point
of mereury, even down to the temperatures
of liquid air and of liquid or solid hydro-
gen. Such thermometers use pentane or
toluene; or a copper-constantan thermo-
couple is employed. For the very lowest
SCIENCE.
167
temperatures helium gas is used, helium
being the only gas not liquefied at the tem-
perature of solid hydrogen, namely, about
16° above absolute zero, or 257° C. (or
430° F.) below the freezing point of water.
The bureau has done more or less testing
in all these lines except the last, but hopes
soon to add this to the list of tests which
are made.
From the temperature of solid hydrogen
to that of the electric are is a wide range,
indeed, and a very considerable equipment
of apparatus and machinery is necessary
to produce and to measure any tempera-
ture throughout this range. For the high-
er temperatures numerous gas and electric
furnaces are required. For the lower tem-
peratures a refrigerating plant and appa-
ratus for liquefying carbon dioxide, air and
hydrogen are required. The bureau has
recently purchased the low temperature
plant which was operated as an exhibit by
the British government at the St. Louis
Exposition. This was one of the most in-
teresting exhibits of the entire world’s fair.
Liquid hydrogen was produced in larger
quantity by this plant than had ever been
done before, more being made and used in
publie demonstrations during the season
than the total amount that has been pro-
duced since hydrogen was first liquefied.
Solid hydrogen is also produced by the
apparatus.
The optical work of the bureau is not so
fully established as the work in weights
and measures and heat and thermometry,
but three well-trained specialists are de-
voting themselves to it and a fourth is soon
to be appointed. The work of research
and testing in this section, which has been
taken up or is soon to be begun, includes
the investigation of the optical properties
of instruments and of materials; the appli-
eation of interference and other optical
methods to linear and angular measure-
ments; the investigation of the spectra of
168
vacuum tubes and other phenomena in con-
nection with the passage of electricity
through gases at reduced pressure; and
the investigation of questions connected
with the polariscopic analysis of sugar and
the testing of polariscopes.
The latter subject is of special impor-
tanee on account of the use of polariscopes
in determining the duty on sugar imported
into the United States. The bureau has
undertaken, at the request of the Treasury
Department, to supervise the work of polari-
seopie analysis of sugar in all the custom-
houses of the country. Sugar is the chief
source of revenue among articles imported,
the duties .collected by the government
amounting to over $60,000,000 per annum.
The duty on each importation is deter-
mined by the angle through which a beam
of polarized light is rotated when passed
through a solution of a sample of sugar,
the percentage of pure sugar being shown
by a specially prepared table when the
angle of rotation has been determined.
For some years a difference has existed be-
tween the experts of the government and
those employed by the sugar interests as to
the effect of temperature upon the indica-
tions of the polariscope, and although the
difference is only a fraction of one per
cent., it amounts to a large sum when ap-
plied to the hundreds of millions of dol-
lars paid in duty during the last few years.
The question is being contested in the
courts and in the meantime the bureau is
making some careful investigations on the
subject in the interest of the government.
Another line of the bureau’s work not
yet fully established is the testing of gas
and water meters, pressure gauges and
manometers for high and low pressures,
engine indicators and the determination of
the strengths of materials including cem-
ents and other building materials. This
will probably develop into a very impor-
tant branch of our work, in which we can

be of much service to scientific and tech-
nical laboratories, as well as to the govern-
ment and the public.
The official testing of scales, measures
of length and volume, gas, water and elec-
tricity meters and other instruments by
which the commodities purchased by the
people are measured is not done in this
country as thoroughly as it ought to be.
In very few cities do the sealers of weights
and measures go about systematically test-
ing the instruments employed for measur-
ing merchandise. England surpasses us in
looking after the interests of the people in
this particular. One of the functions of
the bureau is to educate the public to the
importance of this work. A step in this
direction is the national convention of
sealers of weights and measures to meet
next month in Washington in response to
a call issued by the bureau of standards.
The various lines of testing and research
which have so far been mentioned, namely,
weights and measures, heat and thermom-
etry, hight and optical instruments, and en-
gineering instruments, are included in the
first division of the work of the bureau of
standards. The second division includes
electricity and photometry. In the early
days of its development electricity was es-
sentially a qualitative science; its modern
history has seen it become distinctly quan-
titative, and its wonderful development has
been largely, if not mainly, due to the use
of measuring instruments in studying and
applying it. The three fundamental units
of measure are the ohm, the unit of resist-
ance; the ampere, the unit of current; and
the volt, the unit of electromotive force.
These are so related by Ohm’s law that — |
when two are defined the third becomes
fixed and can be determined by the use of
the other two. These units are not arbi-
trarily chosen, but are determined by ex-
perimental investigation. Their magni-
tudes depend upon the fundamental units

of length, mass and time, and these having
been selected (namely, the centimeter,
eram and second), the definitions or speci-
fications of the electrical units follow log-
leally, but their conerete expression in
actual standards that can be employed in
electrical measurements ean only be at-
tained after most painstaking researches
in what are called absolute measurements.
The two of these three units which have
been so determined are the ohm and the
ampere. As all other electrical units are
based upon these, it is of the greatest im-
portance that they be determined with the
utmost exactness. At the International
Electrical Congress at Chicago, in 1893,
they were redefined in accordance with the
results of the best determinations made up
to that time. The ohm is specified in terms
of the resistance of a column of mercury
106.3 em. long, having a cross-section of
one square millimeter; the ampere in terms
of the quantity of pure silver it will de-
posit electrolytically per second from a
solution; the volt in terms of the electro-
motive force of the standard Clark cell.
An immense amount of work has been done
by numerous investigators in various coun-
tries of the world in the determination of
the values of these electrical units, and the
figures adopted in the definitions un-
doubtedly come very near the truth.
Nevertheless, we know from subsequent
work that at least two of these units are
very slightly in error, and one of the most
important problems before the bureau of
standards is the redetermination of these
fundamental units. The error in ques-
tion is small, so small as to be of no eonse-
quence in engineering and commercial
work. But scientifically it is important,
and as instruments and methods are im-
proved year by year, any small discrep-
ancies in our fundamental units become
of more and more significance. The Na-

the Physikalisch-Technische Reichsanstalt
of Germany and the National Bureau of
Standards, as well as a few private investi-
gators in this country and abroad, are all
working in the same direction. The recent
International Electrical Congress at St.
Louis provided for the formation of an in-
ternational commission, whose function it
shall be to foster and in some degree direct
and coordinate researches of this character.
This commission will probably organize and
enter upon its work during the coming
year. The difficulties to be overcome are
so great that only the most elaborate re-
searches carried out under the most favor-
able circumstances ean be expected to
bring us appreciably nearer the desired
goal. - Two researches at the bureau of
standards during the past year gave re-
sults of value preparatory to the rede-
termination of the ampere in absolute
measure. Orte was by Dr. Wolff, showing
how to overcome one of the defects of the
standard cell; a new method of preparing
the mercurous sulphate yielding a erystal-
line product which gives cells of more uni-
form electromotive foree than formerly.
Professor Carhart, of Ann Arbor, who has
been engaged upon this subject for some
time, arrived independently at the same
result even earlier, the results being an-
nouneed by both men at the same meeting
in Washington in April last. The other
investigation was by Dr. Guthe, who, after
carefully studying all the various forms of
silver voltameters which have been pro-
posed, showed that although different
kinds gave slightly different results, cer-
tain ones when properly handled, gave
practically identical results, and hence
could be depended upon for measuring
eurrent to a very high order of accuracy.
Dr. Wolff is continuing his work on stand-
ard cells and Dr. Guthe is now engaged in
the absolute measurement of current, by
means of a new electrodynamometer.
170
I have been engaged, with the assistance
of Mr. Grover, Dr. Lloyd and several other
members of the bureau, in the absolute
measurement of electric capacity and in-
ductance and in the investigation of elec-
trical measuring instruments, more espe-
cially for the precise measurement of al-
ternating current, voltage and energy.
These investigations have involved the con-
struction of much new apparatus, as well
as the thorough study of some well-known
instruments. One of the practical prob-
lems in connection with the accurate meas-
urement of capacity or inductance is the
determination of the frequency of the in-
terrupter or of the alternating current em-
ployed. This usually amounts to obtain-
ing the speed of some kind of motor, often
an electric motor. For some kinds of work,
to be within one per cent. is considered suf-
ficiently accurate. For other cases one
tenth of one per cent. is none too good.
In still others one hundredth of one per.
cent. is deemed necessary. In this work
we sought to get the frequency to a thou-
sandth part of one per cent. This re-
quired a very perfect control of the speed,
and yet by attention to all the sources of
disturbances, and by the use of a very
sensitive indicator, the desired result was
obtained and an important additional step
taken in absolute measurements.
Many other interesting and important
questions are being investigated, and work
enough for years is already before us.
These particular examples of the work at
the bureau have been cited, not because I
presume that you are especially interested
in the problems themselves, but rather to
illustrate the kind of research work we are
doing.
The work of testing is being carried on
at the same time. Resistance standards,

stone bridges, potentiometers, magnetic in-
struments, current instruments, voltmeters,

wattmeters, condensers, inductances and
many other electrical instruments have
come to us from manufacturers, universi-
ties, technical laboratories and departments
of the national government. To be abie
to get reliable standards and to have in-
struments calibrated at a nominal cost is
a boon to all careful experimentalists.
Heretofore it has often happened that the
burden of the work in a given investigation
has been to calibrate the instruments em-
ployed, and often the facilities at com-
mand were insufficient to yield results of
high accuracy. Within the last three years
(that is, since the bureau has been testing
instruments) there has been a marked im-
provement in the quality of some kinds of
electrical instruments made in this coun-
try. It is now so easy to determine whether
a resistance box guaranteed by the maker
to be correct to one fiftieth of one per cent.
fulfils the guarantee, that the maker is
compelled to use correct standards and to
adjust his resistances carefully in accord-
ance with the same.
Probably the most interesting collection
at the St. Louis Exposition from the stand-
point of physical science was the magnifi-
cent exhibit of scientific instruments made
by Germany. There was a time not so
very long ago when France and England
surpassed Germany in the production of
scientific instruments. But the giant
strides which Germany has made in the
last twenty years has left other countries
in the rear, and this wonderful progress
has been largely due to the wise encourage-
ment and assistance offered to instrument
makers by the German government. This
assistance has taken various forms, but the
principal factor has probably been the work
of the Reichsanstalt and the Normal Aich-
ungs Kommission, the two government
laboratories doing the work which the bu-
reau of standards aims to do in the United
States. They have set a high standard for
FEBRUARY 3, 1905.]
scientific instruments, and have not only
shown how defects could be corrected, but
have developed the theory and the design
of many new instruments. All this has
occurred so recently that it is not gener-
ally known in the United States, and Ger-
man instruments are not as largely used as
they deserve to be. We hope that the next
few years may witness a similar impetus in
the production of scientific instruments in
this country, and that the United States
may come to hold the same enviable posi-
tion with respect to scientific instruments
in general that she now does with respect
to tools and labor-saving machinery and
to certain special classes of scientific in-
struments.
The advantage of having instruments
and standards of high accuracy for engi-
neering and research work is obvious and
needs no proof. I wish, however, to point
out the advantage of using such instru-
ments as far as practicable for purposes of
instruction, especially in the more ad-
vanced laboratory courses. If the appa-
ratus is not accurately adjusted the careful
student and, perhaps, his instructor as well,
is prone to lose valuable time in trying to
locate errors that are inherent in the appa-
ratus, or in striving for a degree of accu-
racy which is unattainable with the instru-
ments employed. On the other hand, when
the apparatus is known not to be correct
it is so easy to attribute to the instruments
any discrepancies in the results that care-
fess reading and hasty work may possibly
be encouraged. It isa great delight to the
real lover of quantitative experimental
work, of whom a great many are to be
found in almost any college class, to do a
piece of work with precision instruments
and obtain an accurate result, duly checked
by proper variations of the experiment.
The educational value of such work is cer-
tainly greater than when only roughly
done; the pleasure derived is incomparably
SCIENCE.
pba
greater. It is by no means necessary that
all the instruments of a laboratory be sent
away to be tested. If only the laboratory
possesses correct standards and suitable
comparing apparatus, the calibration or
adjustment of most of the other instru-
ments furnishes excellent experimental
work for the students and assistants of the
laboratory.
Another important section of the work
of the bureau is photometry. This is really
optical rather than electrical, but owing to
the fact that the chief work is with electric
lamps and a very considerable electrical
equipment is required, it is grouped with
the electrical in our organization. The
standards employed in photometric testing
are less satisfactory than in most other
branches of physical measurements. The
quantity of light emitted by a given source
is usually expressed in candle power; the
ordinary ineandescent electric lamp, being
approximately equivalent to sixteen stand-
ard candles, is called a sixteen candle-
power lamp. The candle as a standard of
measure has passed out of vogue, but hght
is still expressed in candle power. Various
sources of light have been proposed as
standards, the Hefner lamp burning amyl-
acetate, being most used as a primary
standard. As working standards specially
prepared incandescent lamps are generally
used, and are quite satisfactory. Greater
progress has been made in recent years in
developing photometers and the auxiliary
apparatus for comparing lamps than in
perfecting a primary standard of illumina-
tion. Although the initial equipment of
the bureau for this work is not yet com-
plete, we have already done considerable
testing, especially in rating lamps to be
used as standards by manufacturers and
others, and in testing lamps purchased by
the various departments of the govern-
ment. Millions of incandescent lamps are
sold each year on carefully drawn specifi-
cations, and it is a matter of considerable
importance to know whether the conditions
of the contracts are met by the manufac-
turers.
In addition to the exhibit made by the
bureau of standards in the government
building at the St. Louis exposition, an
electrical laboratory was equipped and
the electricity building.
This was done at the request of the exposi-
tion management, the object being twofold;
first to exhibit a working electrical labora-
tory, and, second, to do electrical testing
for the jury of awards, for the railway
test commission, and other electrical in-
terests at the fair. The laboratory build-
ing, which was within the palace of elec-
tricity, and extended along one of its walls
for a distance of about 175 feet, was di-
vided into six rooms. Notwithstanding the
fact that it was a temporary structure the
laboratory possessed many of the appoint-
ments of a permanent installation; and,
although many disadvantages and limita-
tions were experienced in doing scientific
work amid such surroundings, we succeed-
ed in doing a good deal of satisfactory
work, including both research and testing.
So complete a laboratory has never been
installed in any previous world’s fair, and
it proved to be of considerable interest
both to visitors and to those electrical in-
terests which availed themselves of its fa-
cilities for testing instruments. THE MACMILLAN COMPANY “sew'tone”

It is a matter of measurement that but one
fourth of the water in the Niagara River
passes over the American Falls. The sill of
the falls is ten feet higher on the American
side than on the Canadian. How easily the
water is driven entirely out of the American
channel is seen by the ice dams of the past
few years, which, gorging the stream from the
upper end of Goat Island to the American
side, have turned the water from that channel
so that one can cross the bed of the river
dry-shod. Let then, from one fourth to one
third of the water be permanently abstracted
from the river, and the American Falls will
be permanently dry. The production of power
actual and immediately contemplated by the
five companies within their charters will con-
sume 48,400/224,000 of the water, or 1/5 —.
With the estimated abstraction of water by
the sixth (American) company this fraction
becomes 58,400/224,000 or 1/4—. Should the
proposed additional Canadian plans be effected
the proportion will become 88,396/224,000 or
1/3—. In any one of these cases the danger
limit is reached and the perpetuity of the
American Falls now hangs by the slender
thread of improbability that these companies
shall produce to their statutory limitations
or find a market for their product.
It is authentically stated that 800,000 tour-
ists visit Niagara annually, bringing an
enormous revenue to the place. As soon as
the world learns that New York and Canada
have shorn this famous place of its beauties,
this source of industrial prosperity will be
gone. While these magnificent schemes of
power development are putting to shame a
sentiment of proper pride which should be
national rather than local, unlimited horse-
power lies idle in the region where these
companies hope to find their market and in
the development of this none of the finer
manifestations of natural power and none of
the finer sentiments of mankind would be as-
sailed.
The address was a strong presentation of
the subject and the press of the city joined in
the protest against the destruction of the falls.

DISCUSSION AND CORRESPONDENCE.
CONSULTING EXPERTS IN LIBRARIES.
To Tue Eprror or Science: Dr. Francis B.
Sumner’s letter, published in Scrmmncr, Jan-
uary 13, seems to offer an appropriate oppor-
tunity for calling attention to certain note-
worthy developments at the Library of Con-
gress during the administration of Dr. Her-
bert Putnam. Dr. Sumner urges the desira-
bility of employing, in connection with one
of our great libraries, ‘a staff of consulting
_experts, men of the rank of college professors,
whose duty it should be to furnish definite bits
of information in response to legitimate ques-
tions, or, at least, to guide the seeker on his
way * * * the establishment of a sort of hu-
man encyclopedia as an adjunct to the library.’
While this ideal has not yet been attained
at the Library of Congress, a remarkable de-
velopment in this direction has taken place
during the last few years. It is the function
of the Division of Bibliography, established
in 1900, not only to prepare and publish lists
of references on special topics, principally
those of current political interest, but also
to supply bibliographical information in reply
to inquiries received by mail. The reference
work of this character has been mainly in the
fields of social and political science and his-
_tory.
As, however, the collection of scientific lit-
erature has recently been reclassified and is
now in process of being recatalogued, it has
become possible to undertake similar work in
science. There are on the staff of the library
at the present time several specialists repre-
senting different sciences, and it is always
possible to consult others associated with va-
rious branches of the government service.
Furthermore, it being part of the policy of
the Librarian of Congress to make the collec-
tion of bibliographies, indexes, library cata-
logues, etc., as complete as possible, unusual
resources in the way of bibliographical tools
are available at the library. A Science Sec-
tion of the library, in charge of the under-
signed, has accordingly been organized re-
cently and one of its functions is to carry on
the reference work in this field, both for in-
vestigators at the scientific bureaus in Wash-
314
ington and in answer to legitimate inquiries
by mail.
Under these circumstances it seems that the
facilities now offered by the Library of Con-
gress meet the need indicated in Dr. Sumner’s
letter to a very considerable extent, and fur-
ther advances in this direction will occur if
it appears that valuable service can be ren-
dered.
I conclude by inviting the readers of ScinNCE
to make use of these new facilities whenever
the library resources to which they have access
are inadequate to the needs of the investiga-
tions which they have in hand. Communica-
tions should be addressed to the Librarian of
Congress, and should be marked ‘ Science
Section’ if they are-inquiries referring to the
mathematical, physical or natural sciences.

THE STORAGE OF MICROSCOPIC SLIDES.
To tHe Epiror or Science: In your issue
of December 30 you published an article by
C. L. Marlatt, of the U. S. Department of
Agriculture, describing a method of storing
and indexing microscopic slides.
The Bausch and Lomb Optical Company
have designed and are selling an excellent
cabinet with card system which has all the
advantages claimed by Mr. Marlatt for his
and lacking only the envelopes, which I can
not but think must be somewhat inconvenient.
These cabinets are made in three sizes, hold-
ing 500, 1,500 and 3,000 slides respectively.
Tiers of trays, each running in its own groove,
are constructed to take slides of various sizes.
At the bottom are drawers (one, two or three)
containing separate cards for every slide, on
each of which is printed a form for register-
ing the slide: Tray No.—Series No.—Name
of Slide—Stain—Mounted in— and two lines
for other data. There are also printed guide
cards from A to Z.
The objects being recorded on separate
ecards, the removal of slides necessitates
simply the removal of its corresponding card,
while the addition of slides requires only the
filling out and insertion of new cards. Olassi-
fication thus, it will be seen, becomes exceed-
ingly simple. The slides may be rearranged

DOPPLER’S PRINCIPLE AND LIGHT-BEATS.
THERE is a beautiful lecture experiment in
illustration of Doppler’s principle due, I be-
lieve, to Koenig. A vibrating tuning fork
of high pitch, say 2,000 vibrations per second,
is moved to and fro near, and at right angles
to, a reflecting wall. The waves coming from
the fork and (virtually) from its image back
of the wall are changed in length by the op-
posite motions of fork and image with the
result that very audible beats are heard. With
a fork of the pitch mentioned, a speed of
three feet per second gives beats at the rate
of about eleven per second. Although special
forks are made for this experiment, they are
quite unnecessary. An ordinary © 512 fork
of Koenig’s pattern gives a very shrill tone
when strongly bowed near the shank and
answers the purpose admirably. If the fork
is held stationary and the reflecting surface
is moved, the effect is the same on account of
the motion of the fork’s image.
Attempts to secure visible beats by means
of light waves of slightly different wave-length
have met with no success, partly on account
of rapid changes of phase, and partly because
of the difficulty of securing two sources whose
vibration frequencies are nearly enough equal.
Thus if we assume (what is most likely not
true) that the failure to observe interference
fringes with differences of path greater than,
say, 30 em. indicates a change of phase, this
would indicate 10° or more changes of phase
per second. On the other hand, should we
take the two D lines as sources there would
be about 10” beats per second. It is evidently
almost hopeless to attempt to secure visible
light-beats in this manner. If we consider
Doppler’s effect, however, the case is quite
otherwise. The second form of Koenig’s ex-
periment, viz., that in which the reflector is
moved, is in principle almost exactly anal-
ogous to Professor Michelson’s interferometer.
FEBRUARY 24, 1905.]
In this instrument the alternations in bright-
ness at any point in the field when the slide
is moved are beats due to the Doppler effect
just as truly as are those heard in the second
form of Koenig’s experiment.

NOTE ON THE BROAD WHITE FISH.
In the Proceedings of the American Philo-
sophical Society of Philadelphia, XLIIL,
1904, p. 451, plates VIII. and IX., I have
wrongly identified the broad white fish, or
Coregonus kennicotti Jordan and Gilbert, as
the humpback, or Coregonus nelsonii Bean.
My error was due largely to lack of material,
ignorance of the species from autopsy, and
the fact, as I have since discovered, that C.
nelsonit does not always exhibit the well-de-
veloped hump like that of the type. Possibly
when the Siberian forms are carefully studied
the nomenclatures of these fishes will be more
stable.

North America through continuous intermi-
gration over the broad land area now sub-

gigantic proportions. The available timber
per township runs from ‘3,000 feet B. M.
amid the high mountains, up to 59,000 feet
B. M. in the northwest corner’ (Dodwell and
Rixon). What with fallen timber and under-
growth of ferns and shrubs the forest is a
veritable jungle. By hard work one can
travel a quarter of a mile an hour off the
trails!
Salal-berry (Gaultheria shallon) and species
of Rubus, Vaccinium and Ribes contribute
largely to the denseness of the jungle, and
furnish abundant food for man and _ beast.
The matted tree tops admit only a gloomy
light below, and the darkness is deepened by
great blankets of Selaginella (S. oregana) and
bearded lichen (Usnea) depending from the
branches. A thick bed of moss covers all the
ground and swathes the bases of the tree
trunks. Above 2,000 feet, however, the forest
is quite open, but travel is impeded much
more seriously by the impassably sharp hog-
backs and steep canyon walls. The moun-
tains slope more gently southward than on
other sides, and it is believed that Mt. Olym-
pus could be reached from the valley of the
Quiniault River. The major part of the
peninsula is held as the Olympic Forest Re-
serve. Two reports on this by Dodwell and
Rixon (1, U. S. Geol. Surv., 21st Ann. Report,
Part V., 1900; 2, ditto,. Professional Paper
No. 7, 1902) with maps and illustrations give
the best accounts yet available concerning the
region.
The fauna is equal to the flora in richness.
Black bears, panthers, wild cats and wolves
are numerous. A few squirrels and the moun-
tain beaver are found. Deer and elk are
plentiful. The garter snake is the only rep-
tile. Wild duck and pheasants are occasional,
and the familiar robin is seen about the
houses. Salmon and trout of several kinds
abound in all streams that are large enough.
Quiniault salmon is said to be the finest on
the coast. The report of the expedition from
the Field Columbian Museum on the mam-
mals of the Olympic Peninsula is the only
record of its fauna.
In each river valley a distinct tribe of In-
dians originally made its home. The Makah

at Cape Flattery were studied by Swan, and
are an extremely interesting group. ‘The
Quillayutes and Quiniaults would equally re-
pay an immediate investigation; but their old
habits are rapidly vanishing before the gov-
ernment schools. Whites began to settle the
Quiniault Valley in 1892, but the movement
is very slow on account of the difficulty of
clearing land and of getting produce in and
out. It is estimated to cost $200 an acre to
remove the timber enough for farming op-
erations.
Here, then, is almost virgin soil for any
kind of scientific investigation. Just enough
has been done to enable the student to start
intelligently and progress without interrup-
tion on any phase of this interesting region.

QUOTATIONS.
DR. OSLER ON THE PERIODS OF A TEACHER’S LIFE.*
I am going to be very bold and touch on
another question of some delicacy, but of
infinite importance in university life, one that
has not been settled in this country. I refer
to a fixed period. for the teacher, either of
time of service or of age. Except in some
proprietary schools, I do not know of any in-
stitutions in which there is a time limit of,
say 20 years’ service, as in some of the London
hospitals, or in which a man is engaged for
a term of years. Usually the appointment is
aut vitam aut culpam, as the old phrase reads.
It is a very serious matter in our young uni-
versities to have all of the professors growing
old at the same time. In some places only an
epidemic, a time limit, or an age limit, can
save the situation.
I have two fixed ideas well known to my
friends, harmless obsessions with which I
sometimes bore them, but which have a direct
bearing on this important problem. The first
is the comparative uselessness of men above

Hopkins University, given at the annual com-
memoration exercises on February 22, and printed

tion.
394
40 years of age. This may seem shocking,
and yet read aright the world’s history bears
out the statement. Take the sum of human
achievement in action, in science, in art, in
literature—subtract the work of the men above
40, and, while we should miss great treasures,
even priceless treasures, we should practically
be where we are to-day. It is difficult to
name a great and far-reaching conquest of the
mind which has not been given to the world
by a man on whose back the sun was still
shining. The effective, moving, vitalizing
work of the world is done between the ages of
25 and 40 years—these 15 golden years of
plenty, the anabolic or constructive period, in
which there is always a balance in the mental
bank and the credit is still good.
In the science and art of medicine there has
not been an advance of the first rank which
has not been initiated by young or compara-
tively young men. Vesalius, Harvey, Hunter,
Bichat, Laennee, Virchow, Lister, Koch—the
green years were yet on their heads when their
epoch-making studies were made. To modify
an old saying, a man is sane morally at 30,
rich mentally at 40, wise spiritually at 50—
or never. The young men should be encour-
aged and afforded every possible chance to
show what is in them. If there is one thing
more than another upon which the professors
of the university are to be congratulated, it
is this very sympathy and fellowship with
their junior associates, upon whom really in
many departments, in mine certainly, has
fallen the brunt of the work. And herein lies
the chief value of the teacher who has passed
his climacteric and is no longer a productive
factor; he can play the man midwife, as
Socrates did to Thesetetus, and determine
whether the thoughts which the young men
are bringing to the light are false idols or
true and noble births.
My second fixed idea is the uselessness of
men above 60 years of age, and the inealcul-
able benefit it would be in commercial, polit-
ical and in professional life if, as a matter
of course, men stopped work at this age.
Donne tells us in his ‘ Biathanatos’ that by
the laws of certain wise states sexagenarii
were precipitated from a bridge, and in Rome

men of that age were not admitted to the
suffrage, and were called depontani because
the way to the senate was per pontem and
they from age were not permitted to come
hither. In that charming novel, the ‘ Fixed
Period,’ Anthony Trollope discusses the prac-
tical advantages in modern life of a return
to this ancient usage, and the plot hinges on
the admirable scheme of a college into which
at 60 men retired for a year of contempla-
tion before a peaceful departure by chloro-
form. That incalculable benefits might fol-
low such a scheme is apparent to any one who,
like myself, is nearing the limit, and who has
made a careful study of the calamities which
may befall men during the seventh and eighth
decades!
Still more when he contemplates the many
evils which they perpetuate unconsciously and
with impunity! As it can be maintained that
all the great advances have come from men
under 40, so the history of the world shows
that a very large proportion of the evils may
be traced to the sexagenarians—nearly all the
great mistakes politically and socially, all of
the worst poems, most of the bad pictures, a
majority of the bad novels, and not a few of
the bad sermons and speeches. It is not to
be denied that occasionally there is a sexa-
genarian whose mind, as Cicero remarks,
stands out of reach of the body’s decay. Such
a one has learned the secret of Hermippus,
that ancient Roman, who, feeling that the
silver cord was loosening, cut himself clear
from all companions ‘of his own age, and be-
took himself to the company of young men,
mingling with their games and studies, and so
lived to the age of 153, puerorum halitw re-
focillatus et educatus. And there is truth in
the story, since it is only those who live with
the young who maintain a fresh outlook on
the new problems of the world.
The teacher’s life should have three periods
—study until 25, investigation until 40, pro-
fession until 60, at which age I would have
him retired on a double allowance. Whether
Anthony Trollope’s suggestion of a college
and chloroform should be carried out or not,
I have become a little dubious, as my own
time is getting so short.

REPORT OF THE COAST AND GEODETIC
SURVEY FOR 1904.
Tue report of the Coast and Geodetic Sur-
vey for 1904 is a record of manifold labors
and results which have for their theater of
action an area practically coterminous with
that of the United States and all its island
possessions. The main body of the report con-
tains a detailed account of the wide range of
important duties devolving upon this bureau,
and in the appendices we have a presentation
of discussions and results which must prove
of great economical value and interest to sur-
yeyors, engineers, navigators and physicists.
The resurveys and developments impera-
tively required to show the changes in harbors
and approaches, due to works of improvement
or the ceaseless action of natural causes along
the Atlantic, Pacific and Gulf coasts of the
United States, and to meet the ever-increasing
demands of our commerce and navy for up-to-
date charts, particularly of the waters of
Alaska, Porto Rico, Hawaii and the Philip-
pines, gave constant employment to the eleven
vessels available for these duties. The hy-
drography was prosecuted within the limits of
the waters of sixteen states and territories and
the topography was carried on in nine.
In Alaska the work included the continua-
tion of the survey of Prince William Sound,
the survey of Controller Bay and a deep-sea
examination from the Strait of Juan de Fuca
to Prince William Sound, preliminary to the
laying of a deep-sea cable from Seattle to
Valdez. The Porto Rico work was continued
in certain bays and harbors as well as in the
development of the conditions in the off-shore
waters. In the Philippine Archipelago the
survey has secured the cooperation of the
insular government and a detailed résumé
shows a most satisfactory progress of the tri-
angulation, hydrographic, topographic, mag-
netic and astronomical operations. By utiliz-
ing native assistance in the Manila sub-office
twenty-one charts were prepared for publica-
tion during the year, and the outcome of the
experience with Filipinos as draftsmen, com-
puters and engravers is the gratifying demon-
stration that they will prove equally as com-
petent as the Hindoos have been found in the
SCIENCE.
395
British Indian operations and the Malagassys
have proved themselves in the French sur-
veying work in Madagascar.
The reconnaissance for the primary triangu-
lation along the 98th meridian was completed
to the Canadian border and a scheme was ex-
tended eastward connecting this work with
the triangulation of the Mississippi River
Commission. The execution of the primary
triangulation in the Dakotas and Texas was
prosecuted at a rate which surpassed even the
notable record which had already secured an
enviable reputation for the geodetic operations
along the 98th meridian, the total extension
amounting to 300 miles (500 kilometers). An
equal distinction must be accredited to similar
work in California and Oregon whereon re-
markable progress has been made in connect-
ing the transcontinental are work with Puget
Sound.
The progress of the magnetic work is shown
in detail in Appendix No. 3, which includes a
table of results of the magnetic declinations,
dip and intensity of force observed on land
and sea during the year, this being supple-
mented with full descriptions of the magnetic
stations occupied and meridian lines observed.
A new feature is the inclusion of the observa-
tions of the three magnetic elements at sea
by the Coast and Geodetic Survey vessels in
the course of their regular surveying opera-
tions. The paper is replete with matters of
interest to the surveyor, the mariner, the
geographer and the geologist. Thus compre-
hensive examination has been made of certain
locally disturbed areas, as for example, in
Douglas Island, Alaska, in the region of the
local magnetic pole found in 1900; and the
completion of the magnetic survey of Louis-
lana in cooperation with the state geological
survey revealed interesting and important re-
sults as regards both the magnetic distribution
and the secular variation.
The table contains the magnetic results at
384 land stations distributed over 24 states and
territories and 2 foreign countries. The table
of sea results contains 52 entries of magnetic
declination, 34 dips and 32 values of the
total intensity of the magnetic force in the
Atlantic and in the Pacific Oceans. The
396
methods and instruments adopted for the sea
work, which have thus far proved successful,
are described in detail. In a general retro-
spective consideration of the work of the past
five years it is pointed out that in this period
observations have been made at 1,636 stations
of which about one eighth are points previously
occupied by the survey and since used for
observations to secure data for ascertaining
the secular change of the magnetic elements.
The work in about a dozen states has been
practically completed except for special in-
vestigations and secular change observations.
During the year a bureau of international re-
search in terrestrial magnetism has been
created by the Carnegie Institution of Wash-
ington, with the inspector of the magnetic
work of the coast survey in charge as director,
and the cooperation thus ensured is certain to
prove extremely profitable in results.
The determination of the longitude of
Manila from San Francisco, thus completing
the first longitude circuit of the earth, was one
of the astronomical events of the year, and in
Appendix No. 4 is a comprehensive illustrated
report on the various instruments and opera-
tions used in the undertaking with a com-
parative résumé of the various links and re-
sults from which the longitude of Manila had
been determined from the westward. The
generous cooperation of the Commercial Cable
Company, through whose patriotic enterprise
the work was made feasible, is gratefully ac-
knowledged. The results of the determina-
tions from the eastward and westward differ
only by 08.006 or about 8.8 feet. The other
results of this expedition are the determina-
tions by the telegraphic method of the longi-
tudes of Honolulu, and Midway and Guam
Tslands.
The third attempt at representing the tide
for the world at large, the first having been
made by Whewell and Airy and the second by
Berghaus, is described in Appendix No. 5.
The advancement in recent years of the gen-
eral use of the harmonic analysis and the
greatly improved tidal data that are now ob-
tainable for such a great part of the globe
coordinate to make a new presentation of this
subject very opportune. The theoretical dis-

cussion of the problems involved, the wide
range of data and authorities consulted and
referred to, the graphic presentation of the
cotidal lines, the results presented and the
conclusions deduced make a most suggestive
paper and one which will be highly interesting
to all students of the subject.
The results of the precise leveling operations
for the year are published in Appendices Nos.
6 and 7, which submit them in a detail that
makes them immediately available for the re-
quirements of surveyors and engineers. These
extend the precise level net, as previously pub-
lished, six hundred miles to the westward,
from Red Desert, Wyoming, to Owyhee in east-
ern Idaho; and from Holland, Texas, two
hundred miles southwest, to Seguin, Texas.
An interesting feature is an account of the
change in the manner of support for the level-
ing rods, with the comparative discussion of
the old and the new methods and the conse-
quent confirmation of the importance of the
new system.
The account of operations submitted by the
assistant in charge gives the story of the work
of the various computing, drawing, engraving
and chart divisions of the office, in which the
results of the field work are discussed or pre-
pared for the publications and charts wherein
they are placed at the service of the public.
A full account of the first recording transit
micrometer devised for use in the telegraphic
longitude determinations of the Coast and
Geodetic Survey is submitted in Appendix No.
8, with an account of the exhaustive tests it
was subjected to and a recapitulation of the
results of experience with this form of instru-
ment, mainly in Europe, during the last thir-
teen years. The results of these experiments
indicate that with the transit micrometer the
accuracy of telegraphic longitudes may be
considerably increased, if desirable, or the
present standard of accuracy may be main-
tained at much less cost than formerly.
The results of all triangulation in California
south of the latitude of Monterey Bay are
printed in the concluding appendix in full, in-
cluding descriptions of stations, as well as
their latitudes and longitudes and the lengths
and azimuths of the lines joining them. In

compact and convenient form there is given
aul the information in regard to this triangula-
tion that is needed by an engineer or surveyor
who wishes to utilize the results in controlling
and checking surveys or in constructing maps
or charts. The locations of more than 1,300
points are accurately fixed by this triangula-
tion.
The report, in addition to the details of the
foregoing operations and results, contains a
record of a wide range of important work for
which the aid of a survey was sought because
of the special training of its officers. The
superintendent attended the Fourteenth Gen-
eral Conference of the International Geodetic
Association as delegate for the United States
and maintained direction of the observatories
at Gaithersburg, Maryland, and Ukiah, Cali-
fornia, supported by the International Geo-
detic Association for the purpose of measuring
the variations of latitude; he was also detailed
for duty in connection with the presentation
of the case of the United States before the
Alaska Boundary Tribunal being assisted by
one of the officers of the survey. As commis-
sioner of the United States he continued the
work of remarking the boundary line between
the United States and Canada from the Rocky
Mountains westward, two of the officers of the
survey being employed in the field; and as
commissioner of the United States in the In-
ternational Delimitation Commission he in-
augurated the work of marking the boundary
between Alaska and Canada, one of the parties
being under the direction of an assistant of
the survey. One officer continued on duty as
a member of the Mississippi River Commis-
sion. One officer having completed the field
work of the survey of Mason and Dixon’s line,
the boundary between Maryland and Penn-
sylvania, was then detailed to prepare the
maps and report showing the results of the
work. Another officer, at the application of
the municipal authorities, remained in charge
of the triangulation of the Greater New York
territory, and one representative of the survey
in cooperation with the Louisiana Oyster
Commission continued the survey of the
natural oyster beds and reefs for the state of
Louisiana.

THE PRESERVATION OF AMERICAN
ANTIQUITIES.
At a joint meeting of the committees on
preservation of American antiquities of the
Archeological Institute of America and the
American Anthropological Association, held
at the Cosmos Club in Washington, on the
evening of January 10, the subject of pending
legislation was considered. It was decided
that a memorandum should be prepared em-
bodying such provisions from pending meas-
ures, as in the judgment of the joint commit-
tee should be incorporated into law, and the
same presented to the House of Representa-
tives’ Committee on Public Lands, with the
request that a bill should be prepared by this
committee based on these suggestions.
Present: For the Archeological Institute of
America, Dr. Seymour, Chairman, Dr. Put-
nam, Mr. Holmes, Mr. Bowditch, Dr. Kelsey,
Dr. Carroll; for the Anthropological Associa-
tion, Mr. Holmes, Chairman, Dr. Putnam,
Miss Fletcher, Professor Saville, Dr. Gordon,
Mr. Culin, Dr. Kroeber, Mr. Hewett.
The memorandum was submitted by the
committee at the hearing before the Public
Lands Committee on Wednesday, the eleventh.
At the meeting of this committee held on
the sixteenth instant it was ordered to strike
out all except the enacting clause of S.
5603 (the act known as the Lodge-Rodenburg
bill which passed the senate last April) and
insert instead “an amendment in the form of
a substitute”; said substitute being, with a
few minor amendments, the memorandum
prepared by the joint committe above referred
to. The bill as reported back, referred to the
House Calendar, and ordered printed, is as
follows:
Sec. 1. Be it enacted by the Senate and House
of Representatives of the United States of America
in Congress assembled: That for the purpose of
preserving and protecting from despoliation the
historie and prehistoric ruins, monuments, archeo-
logical objects and other antiquities, on the public
lands of the United States, all said historic and
prehistoric ruins, monuments and other objects of
antiquity are hereby placed under the care and
custody of the Secretary of the Interior.
Sec. 2. That the Secretary of the Interior may
make temporary withdrawals of the land on
398
which such historic and prehistoric ruins, monu-
ments, archeological. objects and other antiquities
are located, including only the land necessary for
the preservation of such ruins and antiquities,
and may make permanent withdrawals of tracts
of land on which are ruins and antiquities of
especial importance, not exceeding six hundred
and forty acres in any one place.
See. 3. That the Secretary of the Interior be,
and is hereby authorized to permit examinations,
excavations and the gathering of objects of in-
terest within such reservations by any institution
either domestic or foreign which he may deem
properly qualified to conduct such examinations,
excavations or gatherings, subject to such rules
and regulations as he may prescribe: Provided,
That the examinations, excavations and gather-
ings are undertaken for the benefit of some repu-
table museum, university, college or other recog-
nized scientific or educational institution with a
view to increasing the knowledge of such objects,
and that the gatherings shall be made for perman-
ent preservation and not for commercial purposes.
Sec. 4. That of all excavations and explorations
made under a permit granted by the Secretary of
the Interior, a proper written and photographic
record with plans shall be made at stated periods,
and transmitted for preservation to the United
States National Museum.
See. 5. That the Secretary of the Interior shall
make and publish from time to time such rules
and regulations as he shall deem expedient and
necessary for the purpose of carrying out the
provisions of this act.
Sec. 6. That all persons who shall with-
out permission appropriate, injure or destroy any
public property therein, or injure or destroy any
caves, ruins, or other works or objects of an-
tiquity therein, or commit unauthorized injury or
waste, in any form whatsoever, upon the lands or
objects referred to in this act, or who shall violate
any of the rules or regulations prescribed hereun-
der, shall, upon conviction, be fined in a sum not
more than five thousand dollars, or be imprisoned
for a period not more than twelve months, or
shall suffer both fine and imprisonment, in the
discretion of the court.

of. It is hoped, however, that only a portion
of the fund will be used in procuring the
library and that an adequate principal may
be set aside, the income of which will be avail-
able in maintaining the serials represented in
the library and in otherwise fostering the in-
terests of science. A friend of the institution

Tue legislature of North Dakota has passed
a comprehensive irrigation code which fol-
lows closely the provisions of the suggested
state irrigation code drawn up last summer
by Mr. Morris Bien of the U. S. Reclamation
Service. This is the first effective legislation
on the subject in North Dakota, and will put
irrigation investigation upon a well estab-

possible to secure the exclusive services of a
competent man as a state engineer. ‘The first
state engineer, Professor E. F. Chandler, who
began that work last season and has been

for the establishment of a biological survey
of the potable water of the state to prosecute
a scientific study of aquatic organisms, their
structure, their habits, food, distribution and
variations. Jt is planned to consider such
sanitary problems of a biological character as
may arise in regard to the waters used by and
available for the cities, villages and towns of
the state. The sum of $5,000 is appropriated
for the educational department of the state

$10,000 for salaries of employees. If the bill
becomes a law the work will be under the di-
rection of Professor Clarke.

over to the trustees of the university practi-
cally all her property, including stocks con-
servatively appraised at $18,000,000 and real
estate valued at least at $10,000,000.

The field covered by the present volume is that of direct-current electro-magnetic machinery
and apparatus, and the book is almost exclusively confined to dynamo-electric machinery. The
text refers in numerous places to various books and publications so as to make the book serviceable
in connection with any first-class college course. This also adds to its value as a reference book.
Volume II., in preparation, will deal with alternating-current machinery, etc.
‘It is a book which can be thoroughly recommended to all students of electrical engineering who
are interested in the design, manufacture, or use of dynamos and motors
. .. A distinct
and valuable feature of the book is the list of references at the beginning of each test to
the principal text-books and papers dealing with the subject of the test.

Golumbia University
in the Witn of Hew Bork
Columbia University includes both a college and a university in the strict sense of the words.
The college is Colum-
oia College, founded in 1754 as King’s College. The university consists of the Faculties of Law, Medicine, Philosophy,
Political Science, Pure Science and Applied Science.
The point of contact between the college and the university is the senior year of the college, during which year
students in the college pursue their studies, with the consent of the college faculty, under one or more of the faculties of the
university.
Barnard College, a college for women, is financially a separate corporation ; but educationally, is a part of the system
of Columbia University.
Teachers College, a professional school for teachers, is also, financially, a separate corporation; and also, educa-
tionally, a part of the system of Columbia University.
Each college and school is under the charge of its own faculty, except that the Schools of Mines, Chemistry, Engi-
neering and Architecture are all under the charge of the Faculty of Applied Science.
For the care and advancement of the general interests of the university educational system, as a whole, a Council
has been established, which is representative of all the corporations concerned.
I. THE COLLEGE.
Columbia College offers a course of four years, leading to
the degree of Bachelor of Arts. Candidates for admission to
the college must be at least fifteen years of age, and pass
an examination on prescribed subjects, the particulars con-
cerning which may be found in the annual Circular of
Information.
Barnard College, founded in 1889, offers for women a
course of four years, leading to the degree of Bachelor of
Arts. Candidates for admission to the college must be at
least fifteen years of age, and pass an examination on pre-
scribed subjects, the particulars concerning which may be
found in the annual Circular of Information.
II. THE UNIVERSITY.
In a technical sense, the Faculties of Law, Medicine,
Philosophy, Political Science, Pure Science, and Applied
Science, taken together constitute the university. These
faculties offer advanced courses of study and investigation,
respectively, in (@) private or municipal law, (b) medicine,
(ec) philosophy, philology and letters, (d@) history, economics
and public law, (e) mathematics and natural science, and (/)
applied science. Courses of study under all of these facul-
ties are open to members of the senior class in Columbia
College. Certain courses under the non-professional facul-
ties are open to women who have taken the first degree.
These courses lead, through the Bachelor’s degree, to the
university degrees of Master of Arts and Doctor of Phi-
losophy. The degree of Master of Laws is also conferred
for advanced work in law done under the Faculties of Law
and Political Science together.
III. THE PROFESSIONAL SCHOOLS.
The faculties of Law, Medicine and Applied Science, con-
duct respectively the professional schools of Law, Medicine,
and Mines, Chemistry, Engineering and Architecture, to
which students are admitted as candidates for professional
degrees on terms prescribed by the faculties concerned. The
faculty of Teachers College conducts professional courses
for teachers, that lead to a diploma of the university.
1. The School of Law, established in 1858, offers a course
of three years, in the principles and practice of i=
and public law, leading to the degree of Bachelor of laws.
2. The College of Physicians and Surgeons, founded in
1807, offers a course of four years in the principles and practice
of medicine and surgery, leading to the degree of Doctor ot
Medicine.
3. The School ot Mines, founded in 1863, offers courses ot
study, each of four years,leading to a professional degree, in
mining engineering and in metallurgy.
4. The Schools of Chemistry, Engineering and Architect-
ure, set off from the School of Mines in 1896,offer respect-
ively,courses of study,each of four years,leading to an appro-
priate professional degree, in analytical and applied chem-
istry ; in civil, sanitary, electrical and mechanical engineer-
ing; and in architecture.
5. Teachers College, founded in 1888 and chartered in
1889, was included in the University in 1898. It offers the fol-
lowing course of study: (a) graduate courses leading to the
Master’s and Doctor’s diplomas in the several departments
of the College: (6) professional courses, each of two years,
leading to the Bachelor’s diploma for Secondary Teaching,
Elementary Teaching, Kindergarten, Domestic Art, Domes-
tic Science, Fine Arts, Music and Manual Training ; (c) a col-
legiate course of two years, which, if followed by a two-
year professional course, leads to the degree of Bachelor
of Science. Certain of its courses may be taken, without
extra charge, by students of the University in partial fulfill-
ment of the requirements for the degrees of Bachelor ot
Arts, Master of Arts, and Doctor of Philosophy.
The price of the University Catalogue is twenty-five cents
postpaid. Detailed information regarding the work in any
department will be furnished without charge upon applica-
tion to the Secretary of Columbia University. New York.

THE STORY OF THE FRENCH REVOLUTION
in THE HISTORIANS’ HISTORY OF THE WORLD
(Published by THE OUTLOOK, New York
and: The History Association, London.)
HE proper study of mankind is history. Withoutit you are unenlightened. But how
can you study it in the universal sense. There are 400,000 histories in the Bibliotheque
Nationale of France alone, 300,000 in the British Museum. 5,000 new ones are pub-
lished yearly in the chief civilized countries. Today you are invited to read 28 volumes
on the United States ; yesterday it was 17 volumes on the Tudor period in England.
You do not know the elements of world-history without which you are ungrounded and
narrow-minded. You have lacked a modern scholarly world-history. You are lost in a labyrinth
of diverse books.
THE HISTORIANS’ HISTORY OF THE WORLD comes to your rescue. We wish to send
you without cost, one specimen volume to prove that the editors have discovered the only satis-
factory scholarly method of presenting world-history. They present in the actual words of all
the greatest historians and history makers who have ever lived, with original contributions from
the most scholarly living writers.
We will send you Volume XII. on France from 1715 to 1815, the period of the Revolu-
tion because it is intensely interesting and instructive. We are sure it will give you seven even-
ings at home of continuous intellectual profit and pleasure.
Its 420,000 words include the best writings of 186 great or valuable authorities on French
history. Two thirds of the book has been specially translated from the French.
You start with a special essay by Professor Alfred Rambaud, the first living historian of
France, explaining the exact causes of the Revolution. Presently you come to John Law’s
‘Mississippi Bubble ’’ and ‘‘ frenzied finance ’’ schemes, described by P. E. Levasseur. The Duc
de St. Simon reveals the vileness of Louis XV’s court. The de Goucourts portray Madame de
Pompadour and ‘‘ Cotollin I.’’ who cost 500,000 lives from Rossbach to Quebec. Many hundred
passages of keenest interest treat of war, politics, American colonies, women, philosophy, literature.
Then the Revolution.—‘‘ Night and Orcus burst forth. . . . A world destroyed and en-
gulfed.’’ Here we can but notice at random odd striking passages—remember that the history is
exhaustive, scientific, detailed, consecutive, coherent. M. Thiers, the leading French Statesman
of the nineteenth century, writes of the Constituent Assembly and how poor Louis XVI. toyed
with the Revolution, losing his own head, and how many others! In words of immortal vivid-
ness Thomas Carlyle shows us the Bastile falling.
You live through the Reign of Terror, the guillotine orgies, noyades and fusillade that
cost at least 20,000 lives. The poet-statesman Lamartine depicts poor Charlotte Corday’s
career and execution for killing Marat. Nobler phases are appreciated. France’s marvellous
fight against all Europe is described by H. Carnot, son of ‘‘the organizer of victory.’’ Robes-
pierre dragged with a broken jaw to the guillotine is the climax of the Terror.
‘© A whiff of grapeshot ’’ and Napoleon holds the stage. His victories from Rivoli to Fried-
land are described by Henri Martin, Victor Duruy and many others. Then the debacle. The
finest battle picture ever penned, Victor Hugo’s Waterloo, brings that catastrophe before your
eyes, while industrious writers like Sir Archibald Alison, and Baron Jomini supply lacking de-
tails. In short, this is the most complete and accurate, yet dramatic, presentation of the most |
dramatic period in all modern history.

ALPHEUS SPRING PACKARD.
ALPHEUS SPRING Packarp, for twenty-
six years professor of zoology and geology
in Brown University, died at Providence,
February 14, 1905. He was born at Bruns-
wick, Maine, February 19, 1831. His
father, for whom he was named, was for
over sixty years connected with the Bow-
doin College faculty, and his grandfather,
the Rev. Dr. Appleton, was one of the early
presidents of the college.
At the age of eighteen he entered Bow-
doin and there came under the infiuence
and instruction of the late Paul Ansel
Chadbourne, who fostered and encouraged
his natural inclination towards zoological
work. Dr. Chadbourne at this time was
also connected with Williams College and
it was through him that Packard became a
member of the Williams College expedi-
tion of 1860 to Greenland and Labrador,
with which he went only as far as Labrador,
where he spent two months collecting, get-
ting back to college in time for the studies
of senior year. In the senior vacation he,
with several other Bowdoin students, went
on a dredging trip to the Bay of Fundy.
Immediately after graduation in 1861
he accepted the position of entomologist to
the newly established scientific survey of
Maine and in this capacity he traveled
through a large part of the northern wil-
derness of the state. On this expedition he
made the first discovery of Silurian fossils
in the northern part of Maine and obtained
material for several articles which were
published in the first two reports of the
survey.
402
He had now decided on his life work
and after the season in the field, went to
Cambridge to’ study with Agassiz. Here
he devoted himself largely to the study of
insects for the three years that he retained
his connection with the Museum of Com-
parative Zoology, but in his spare time he
read medicine and each winter he attended
the lectures in the Maine Medical School
connected with Bowdoin, from which he
was graduated with the degree of doctor
of medicine in 1864.
In the summer of that year he made a
second trip to Labrador, where, with his
enlarged experience, he was able to add
greatly to the knowledge acquired on his
former trip. As a result, besides several
smaller papers, he published a large me-
moir on the geology and zoology of that
region. Later this material was worked
over and formed the basis of his book on
‘The Labrador Coast.’
On his return from this second trip to
Labrador he enlisted for three years as
assistant surgeon and accompanied the first
regiment of Maine Veteran Volunteers to
Virginia, where he served until the end of
the war. These ten months included the
whole of his medical practise. After be-
ing mustered out he acted for a time as
librarian and custodian of the Boston So-
ciety of Natural History, remaining there
until 1866 when with several of his former
fellow students—Hyatt, Morse, Putnam
and Cooke—he accepted a position in the
museum of the Essex Institute at Salem,
at that time one of the most active scientific
societies in the country.
Then came the founding of the Peabody
Academy of Science in Salem. To it the
Essex Institute transferred its collections
and the scientific corps went with them,
Packard being appointed curator of inverte-
brates and in 1876 director of the academy.
Here he remained until 1878, when he ac-
cepted the position at Brown which he held
SCIENCE.
[N.S. Vou. XXI. No. 533.
for the rest of his life. While at Salem he
held various other positions. He was for
three years state entomologist of Massa-
chusetts, lecturer for several years in ento-
mology at the Amherst and Orono Agricul-
tural Colleges, and for two or three years
upon zoology and comparative anatomy at
Bowdoin College. He also worked for
two summers on the Bache and Blue Light,
dredging for the U. S. Fish Commission
in the Gulf of Maine. He was connected
for a time with the Kentucky Geological
Survey, when he made a zoological explo-
ration of Mammoth Cave and laid the
foundation of his later work on eave life.
From 1875 to 1877 he was one of the zool-
ogists of the U. S. Geological Survey under
Hayden.
In 1873 Agassiz inaugurated the Ander-
son School of Natural History on the
island of Penekese, the first summer school
of biology in America. Here for two years
Packard gave the instruction in insects
and ecrustacea, and when with Agassiz’s
death the school was given up, Packard
started a similar but smaller summer labo-
ratory at Salem under the auspices of the
Peabody Academy of Science which he con-
ducted until his removal to Providence.
This work was later taken up by the late
Professor Hyatt at Annisquam, Mass., and
continued until the establishment of the
Marine Biological Laboratory at Woods
Hole. In 1876 he was appointed by the
President a member of the U. S. Entomo-
logical Commission which was to devise
ways and means of checking the ravages
of the Rocky Mountain locusts in the trans-
Mississippi country. Later the scope of the
commission, which lasted for five years,
was enlarged so that it might deal with
other insect pests. On this service he made
two trips to the west, one taking him to the
Pacifie coast.
Besides these trips he spent the winter
of 1869-70 in Florida, stopping on his re-
Marcu 17, 1905.]
turn at Beaufort, N. C., from which place
he brought back large collections of inver-
tebrates. The next winter he spent at
Charleston, S. C., where he’studied the de-
velopment of numerous marine inverte-
brates and especially of the crustacea, and
where he collected the tertiary molluscs
made known by F. 8. Holmes. In 1872 he
visited Europe, studying the collections of
insects in the large museums and paying
especial attention to Walker’s types of
lepidoptera in the British Museum. In
1885 he visited Mexico and in 1898 again
spent a year in Europe and northern.
Africa.
Dr. Packard was a most indefatigable
worker, the list of papers which came from
his pen being numbered by hundreds.
Only a few of these can be mentioned here.
His first article was upon the army worm
and was published by the Maine Scientific
Survey. The years at Cambridge were
chiefly spent in study, but some of the notes
then made were incorporated in numerous
later works, although large numbers of ob-
servations made in these early years re-
mained unpublished at his death. His first
large work was the monograph of the geo-
metrid moths published by Hayden’s Sur-
vey, and scarcely less imposing was his
account of the Bombycide issued by the
National Academy. His embryological
work, which included studies on the devel-
opment of the lower insects, appeared in
the ‘Memoirs’ of the Peabody Academy of
Science and in minor papers elsewhere,
while his memoir on the development of
the horseshoe crab remained for years the
chief source of our knowledge of that in-
teresting animal. This work was all done
before the days of sections and was based
entirely upon surface views and optical see-
tions, a fact for which allowance should be
made when his mistakes are recalled. His
papers on the geology and natural history
of Labrador and on the cave animals have
SCIENCE.

already been alluded to. Possibly his best
article was the ‘Monograph of the Phyllo-
pod Crustacea’ published in the last report
of Hayden’s Survey.
Packard was possibly best known for, his
text-books. The earliest of these was his
‘Guide to the Study of Insects,’ which for
years served as the vade mecum of hun-
dreds of budding entomologists. Then
came his ‘Life Histories of Animals,’ which
was the first attempt since the day of Agas-
siz’s Lowell Institute lectures to summarize
the facts of embryology, a work which was
early superseded by Balfour’s admirable
treatise. Then came his ‘Zoology,’ the first
attempt to give American students a truly
scientific text-book in which morphology
and classification were given equal promi-
nence. This was followed by several small-
er and more elementary works for lower
schools, some of which have had a large
sale. Later came a second work on ento-
mology, in which the morphological side of
the subject was strongly emphasized.
Packard, along with his friends Cope
and Hyatt, must be regarded as one of the
founders and chief supporters of the so-
called Neo-Lamarckian school of evolution,
and his writings in advocacy of these views
are numerous. His studies in this direc-
tion led him to study deeply the writings
of Lamarck and later to bring together all
the known facts in the life of this early
apostle of evolution. In fact his second
trip to Europe was largely for the purpose
of ascertaining everything possible concern-
ing the man.
In speaking of Dr. Packard one should
not forget the services he rendered to sci-
ence as one of the founders and for twenty
years as editor of the American Naturalist.
Almost as soon as he reached Salem the
magazine was launched and while one by
one the other editors dropped out Packard
remained in charge. In these days of nu-
merous natural history magazines one can
404
hardly realize the boon the establishment of
this journal was to the naturalists of the
country, and few know its financial vicis-
situdes and the sacrifices of its editor dur-
ing its early days.
Personally, Dr. Packard was one of the
most companionable of men. He was al-
ways ready to aid and assist the young in
their natural history studies to the extent
of his powers. He was critical of the lan-
guage in which they clothed their facts and
the pages of the Naturalist have profited by
his revision. He rarely indulged in con-
troversy, and although he could say sharp
and eutting things, one may look in vain
in his published works for any traces of
polemics.
Dr. Packard was married in 1867 to
Elizabeth Derby, the daughter of the late
Samuel B. Walcott, of Salem, who, with
four children, one a rising naval architect,
survives him.

ALPHEUS SPRING PACKARD.*
I have not known Professor Packard as
long, nor as intimately, as many of my col-
leagues; and where they have spoken I
should remain silent. Neither am I quali-
fied to discuss his more immediate scientific
work. I can, however, in response to the
President’s suggestions, speak of him in the
light in which one scientific man sees an-
other, older and wiser than himself; but I
do so with diffidence. I have, therefore,
written down with some care the things
which I would not otherwise venture to
express.
It seems an ungracious confession to
make, but it is nevertheless true, that it was
through Professor Packard that many of
us in Washington, twenty or thirty years

ago, became aware of the existence of scien-
tifie activity at, Brown University. For
age had wearied the enthusiasm of Alexis
Caswell twenty years earlier. Yet it was
not by his presence that Packard repre-
sented her; at least in the years in which
I knew him, he was not a frequent attend-
ant at scientific meetings remote from
Providence. It was his untiring and re-
markably pervasive industry that con-
fronted us. The president of the National
Academy, the director of the Geological
Survey and others in authority all felt the
force of it; and at one time there were dis-
mal mutterings in the high places of legis-
lation asking why the public printer’s time
should be spent in bringing out the elab-
orate researches of one who stood remote
from public office. How did this come
about? Certainly a man of Professor
Packard’s singular modesty, of his almost
morbid habit of self-depreciation, was the
last to find his way through the mazes of a
government lobby. His transparent sin-
cerity would have been infinitely removed
from all this. And yet there was no mys-
tery about it. It was a mere force from
within breaking its way. The power of
Professor Packard’s intellect bearing on
subjects of natural history, the scope and
accuracy of his learning and the purity of
his scientific ideals were his only resources;
and wherever institutions needed the fruits
of ripe scholarship to dignify their own
scientific activities, these were the first to
feel the influence of Professor Packard’s
productive zeal, as they were compelled to
guide its progress. And so our unobtru-
sive colleague taxed the people of the whole
United States to publish his magnificent
memoirs—because he was genuine.
The same facts appear in a different
way, in the further story of Professor
Packard’s life. I am the last man to speak
lightly of the young vigor and the promise
of our American institutions, or of our
Marcu 17, 1905.]
learned societies. But it is nevertheless
true that in comparison with the famous
academies of the old world we are as yet
mere children. In a history of the essen-
tials in the progress of science, there is but
rare need of the mention of American ac-
complishments. We have much of the
practise, and we show a degree of inde-
pendence in our imitations; but we lack
the philosophic depth, the intuitions and
the profound originality. It is to the law-
giver of science that the true academy is
born, and it is by her lawgivers again that
it must be nurtured. To men of exquisite
genius no climate within the whole range
of our immense country has yet been con-
genial. ‘
We are apt to smile at the Englishman
for the letters which decorate his name.
We laugh at the German for his titles and
at the Frenchman for his ribbons and his
uniform. We smile because to us such
insignia mean nothing; and it is to our
shame. We forget that these symbols voice
a sentiment of almost religious purity. We
have not yet learned to constitute nor even
to revere a tribunal so august as to be in-
compatible with pettiness. We never ask
why the F.R.S. is inseparable from the
names of Lord Kelvin, of Lord Lister, even
in their age and amid the splendors of their
glory. To make the French Academy,
even on its scientific side, required: the
brains of Cuvier, of Lamarck, of St. Hil-
aire, of Buffon, of the brothers Jussieu, of
Pasteur ; it required Laplace, Lavoisier and
Lagrange, Carnot and Cauchy, Fresnel and
Fourier, Ampére and Arago, Poisson and
Poinsot, to mention only a few; and the
dictum of the academy arbitrates with the
authority of these tremendous names.
Precisely to such bodies of inexorable
eritics did the intrinsic strength of the
work of Professor Packard ultimately ap-
peal. And it was from the judgment of
his confréres, from the men who had them-

405
selves traversed the same intellectual terri-
tory and knew it, that he reaped his su-
preme honors. From these alone could the
reward have come; for below the decisions
of his peers, there was no other guide but
conscience.
Few of us realize how difficult it is, what
persistent convictions, what sturdy vigil-
ance is required to enter seriously into
competition with the whole world, as Pack-
ard did; indeed one might say to enter
handicapped, against a world richer in its
traditions, more refined in its higher intel-
lectual atmosphere, more bountiful in its
opportunities, than our young country. It
takes courage to press forward alone, self-
reliant, misunderstood, at peace only with
one’s own convictions. Did we think of
this in Packard’s case? Did we look at his
Linnean and other honors in this hght?
Did even our corporation feel that the
cause of which it is the supreme guardian,
had in Packard been awarded with the most
cherished tokens of the world’s approval?
Packard was not lacking in his reverence
for art, for literature, for music; but his
soul cried out for science. He felt instinet-
ively that the handiwork of man, however
sublime, can not be more than human; and
that a finite brain has fashioned all its eul-
tures. Nature is the offspring of omnis-
cience. He realized what the world was
so slow to realize, what only within the last
few hundred years has come like a tumul-
tuous awakening, that the universe was
wrought in the workshops of God, and that
she alone is ultimately divine. He felt too
that her true poetry is not written in rhet-
orie but in mathematics and in the stern
logie of science. For all our natural phi-
losophies are but an attempt at a picture.
We find no adequate symbols in our efforts
to restate her methods; our analogies, our
metaphors, are gross; we have to shift, to
approximate, to neglect. But nature neg-
406
lects nothing! To her the infinitely large
and the infinitely small on the boundaries
of which we live are alike finite among her
infinities. Touch her at any point and
your contact is with the eternal.
To contemplate the prolific labors of Pro-
fessor Packard is to stand face to face with
the attributes of genius. I do not wish to
make an over-statement. True, there is
an order of genius among the geniuses, but
there is none in whose heart the sacred fire
does not burn. There can be no holier joy
than the joy of creative work, and yet it is
a joy akin to terror. What is it which pos-
sesses a man even in early youth, which
impels him despite all obstacles and re-
straint to strive evermore, intellectually
alone, without approval, profitlessly after
an unattainable ideal; whose spell grows
more potent as his years ripen, as his toil
increases, as the world grows caustic in its
rebuke; and that leaves him only with
death? Do not suppose that the poet or
the sculptor or the martyr alone have it.
It burns to-day with subdued passion but
with all its pristine and unmitigated fierce-
ness in the life of every true student of
nature.
What is it that can sustain a man when
every new avenue of thought discovered is
but the approach to countless avenues be-
yond; when to finish, be it after years of
labor, is only to be ready to begin; what
encourages him when the unknown looms
with greater vastness as the known is more
profoundly mastered; when the very pin-
nacle of attainment is the sublime con-
sciousness of ignorance, and when to be
most renowned is to be most devoutly
humble? It is the inspiration which il-
lumined the life of our friend, our eol-
league, our teacher. Long may his ideals
guide us at Brown!

THE ASTRONOMICAL AND ASTROPHYSICAL
SOCIETY OF AMERICA.
Tue sixth meeting of the society was
held December 27-30, 1904, at Philadel-
phia, Pa., during convocation week, in
affiliation with the American Association
for the Advancement of Science.
Three sessions of the society for the read-
ing and discussion of papers and the trans-
action of business were held in room 106,
College Hall, University of Pennsylvania,
on Wednesday, Thursday and Friday
afternoons. The number of members pres-
ent at some time during the meeting was
thirty-six and the average attendance was
about fifty.
A pleasant social feature connected with
the meeting was an informal dinner at the
Hotel Walton, Thursday evening, at which
twenty-six members and friends were pres-
ent. Through the courtesy of Director
Doolittle, a number of the members had the
pleasure of examining the equipment of
the Flower Observatory of the University
of Pennsylvania at Upper Darby, and by
the courtesy of Professor Snyder the ex-
tensive astronomical equipment of the
Philadelphia Observatory was inspected by
a considerable party.
During the meeting five new members
were elected. The selection of a time and
place for the next meeting was left open
for future action by the council.
The officers elected were:
For 1905:
President—Simon Newcomb.
First Vice-President—George E. Hale.
Second Vice-President—W, W. Campbell.
Treasurer—C. L. Doolittle.
For 1905-6:
Councilors—W. S. Eichelberger, Ormond Stone.
On account of the contemplated absence
from the country of G. C. Comstock for the
ereater part of the year 1905, W. S. Eichel-
berger was elected by the council as acting
secretary.
Marcu 17, 1905.]
W. 8S. Eichelberger and C. L. Doolittle
represented the society in the council of
the American Association for the Advance-
ment of Science.
By request of a committee of the Na-
tional Academy of Sciences appointed to
secure international cooperation in solar re-
search, a committee from this society was
appointed by the president during the
preceding summer to cooperate with the
committee of the National Academy. The
council has made this a standing committee
of the society.

ABSTRACTS OF PAPERS.
The Constant of Aberration: C. L. Doo-
LITTLE.
The systematic observation for variation
of latitude was begun by the author De-
cember 1, 1889. This work has been kept
up with some interruptions since that time.
In 1896 was begun at the Flower Observa-
tory a series which it was proposed to con-
tinue on a uniform plan for a period of
seven years. This design was carried out
with but little departure from the original
program. Observation on this series was
terminated December, 1906.
Work is now in progress on a more com-
prehensive plan, two instruments being em-
ployed, viz., the 54-inch zenith telescope
and the 8-inch Wharton reflex zenith tube.
The close of the former series seems to
mark the proper time for bringing together
the values of aberration constant which
have been obtained, and for combining
them to form a mean which may be con-
sidered final so far as may be shown by
these observations.
The different values found are as fol-
lows:

as the following ones. It has accordingly
‘been assigned the wt. 1, the four remaining
walues being given the wt. 2. Combining
according to these weights, we find for the
mean,
I wish this to be regarded as the defini-
tive value of this constant as derived from
the zenith telescope observations extending
from December, 1889, to December, 1903.
The Test of a Transit Micrometer: JoHN
F.. Hayrorp.
When, in connection with an astronom-
ical transit as used for time observations,
a transit micrometer and chronograph are
substituted for a system of fixed lines in
the diaphragm, a telegraphic key and a
ehronograph, the observer is relieved of
the necessity of operating the key at, or as
soon as possible after, each of the several
instants of transit of the star across the
fixed lines. Instead; he is required simply
to keep the star image bisected continuously
iby the movable micrometer line during its
progress across the field of view. In the
new process of thought the element of time
enters only in an indirect manner. Hence,
with a transit micrometer the personal
equation becomes so nearly zero, and its
variation so nearly zero, that it is difficult
to prove that they are not both absolutely
zero. The personal equation is one of the
most serious sources of error in all time
determinations and determinations of right
ascension. The destiny of the transit
micrometer is to produce a decided increase
in accuracy in this class of observations
without inerease of effort or cost.
‘The observation of star transits by means
“of a movable transit line was first suggested
in 1865 by Director Carl Braun of the
Kalocsa Observatory. He believed that
it was necessary to have the movable line
‘driven by clockwork. He failed to con-
struct a satisfactory apparatus.
SCIENCE.
[N.S. Von. XXI. No. 533.
Repsold, the well-known instrument-
maker, was the first to suggest in print, in
1889, that no elockwork is required. He
constructed a hand-driven transit microm-
eter with which excellent results were se-
cured.
The Prussian Geodetie Institute put the
Repsold hand-driven transit micrometer
into use on portable instruments in making
telegraphic longitude determinations in
1891, and has continued its use to the pres-
ent time. In all, it has been used in ten
longitude determinations.
Utilizing the published past experience
with transit micrometers Mr. E. G. Fischer,
chief of the Instrument Division, Coast
and Geodetie Survey, designed and con-
structed in the winter of 1903-4 the tran-
sit micrometer which is before you, and
which is adapted for use on the transits
ordinarily used in longitude determina-
tions.
It is a hand-driven transit micrometer.
It is so well designed and constructed
that in the extensive tests, to which I will
refer in a moment, it never required the
slightest change in adjustment, not even of
the pressure of the contact spring, and not
a single record was ever lost on account of
any failure of the transit micrometer to
operate properly.
A peculiar and important feature of
this transit micrometer is an automatic
switch which operates, without the slight-
est attention from the observer, in such a
manner that a record is made on the
chronograph for the middle four turns of
the field, and for those turns only. This
positively identifies those four turns, keeps
the chronograph sheet clear, and enables the
observer to practise following the star dur-
ing the earlier part of its transit without
affecting the chronograph sheet in any
way.
In Mareh, April and May, 1904, this in-
strument was tested by 75 time sets on 18
Marcu 17, 1905.]
nights at the Coast and Geodetic Survey
office. Sixteen observers took part in this
test. The observers were purposely se-
lected so as to include some with little or
“no experience in any kind of observation,
some with long experience in astronomic
observations and in handling various in-
struments of precision, and some of various
erades between these two extremes. Two
observers worked at the same time, observ-
ing alternate stars, and thus obtaining a
determination of their relative personal
equation. One of the sixteen observers
was in the test continuously, became thor-
oughly accustomed to the instrument and
method of observation, and served as an
intermediary through which all the other
observers could be compared with each
other.
The tests show that for a practised ob-
server with such a transit micrometer, the
total error for a star, including errors
which are constant for all the records as
well as the accidental errors of bisection,
is nearly the same for stars of all declina-
tions if expressed in angular measurement.
This is what should be expected if the
errors concerned are of the same nature as
if the object pointed upon were stationary
instead of moving.
The accidental errors of bisection are
nearly the same expressed in angular meas-
ure for stars of all declinations up to 59°,
and are probably somewhat less for stars
of greater declination. This is an indi-
cation that the accidental errors of bisec-
tion are of the same nature as if the image
pointed upon were stationary, the indica-
tion being partly contradicted by the
smaller errors for stars of declination
ereater than 58°.
Good observations can be secured at once
with the transit micrometer without pre-
vious practise. Practise simply reduces the
accidental errors by about 25 per cent.
I feel that I may speak with assurance on
SCIENCE.

this topic, for each of the sixteen observers
was foreed to begin observing on the first
star that appeared in his field of view,
with no previous experience whatever.
This point is emphasized for the reason
that I had been led to expect that long
practise would be necessary before an ob-
server could be sent to the field with a
transit micrometer. ‘The accidental error
of a single record with the transit microm-
eter is about the same as that of a single
record with a key.
During the first half of the tests the
driving heads were geared to make one
turn in 28.4, when observing an equatorial
star. During the last half of the tests the
driving heads were geared to turn one half
as fast, namely, one turn in 48.8. This ex-
treme change in speed produced surpris-
ingly little effect on the accuracy of the
result. With this instrument the speed of
45.8 per turn, or possibly a slightly slower
speed, is believed to be most favorable to
accuracy.
The tests show that the relative personal
equation between any two observers with
the transit micrometer is so small as to be
masked by the accidental errors of observa-
tion. This is equivalent to saying that it
is probably less in every case than 8.05, and
is, as a rule, much smaller than this. The
relative personal equation with a transit
micrometer is certainly not more than one
tenth as large, upon an average, as with a
key. This conclusion as to the relative
personal equation applies to inexperienced
as well as experienced observers.
The literature of the transit micrometer
shows abundant corroboration of these con-
clusions as to the relative personal equa-
tion.
It is diffieult to detect constant or sys-
tematie errors of any kind in transit mi-
erometer observations. All the errors
seem to belong to the accidental class.
410
This is far from being true of key observa-
tions.
The transit micrometer is about to be
put into use in the regular longitude work
of the Coast and Geodetic Survey.
I predict, basing my prediction upon the
general experience with transit micrometers
as well as on these particular tests, that
with a transit micrometer three nights of
observations without an exchange of ob-
servers will give as great accuracy as has
been secured in the past from ten nights
of observations with a key, including an
exchange of observers. This is a predic-
tion of which the truth cr falsity can only
be proved conelusively by field experience.
I rely upon such experience to be gained
within the next five years to verify the
prediction.
I venture to predict also that the evi-
dence in favor of the transit micrometer
wil! accumulate to such an extent in the
next ten years in fixed observatories, as
well as with portable instruments, that the
astronomer who uses a key in 1914 for
accurate time determinations or determina-
tions of right ascension will have difficulty
in furnishing adequate explanation of his
conduct.
An illustrated description of the Coast
and Geodetic Survey transit micrometer,
with a full report of the tests referred to
above, and a brief résumé of a part of the
literature of the transit micrometer, is now
being printed as an appendix to the Coast
and Geodetic Survey Report for 1904.
Remeasurement of the Hough Double

The catalogues of new double stars pub-
lished by Professor Hough comprise 622
pairs, of which 77 are closer than 3” and
143 closer than 1”; in those pairs in which
the distance is greater than 5” the com-
panion is usually excessively faint; in fact,
there are few of the stars which would not

be difficult with a telescope of much less
than 18 inches aperture.
The measurement of this fine series of
doubles seems to have been strangely
neglected. On a few of them, which are
of the type of close pairs of equal magni-
tude, as 98, 260 and 296, there are a num-
ber of rather discordant measures, but the
creat majority have received no attention
except from the discoverer himself. Thus
there are but 87 pairs which have been
measured in two different years, and on
no less than 358 there is but a single prior
measure.
The entire list was, therefore, added to
the observing list for the 18-inch refractor
of the Flower Observatory. Thus far, 360
pairs have been measured on three or more
nights and many of the remaining 262 are
partially measured; a single night’s meas-
ure consists in each case of at least four
measures of position angle and four of the
double distance.
Change has been found in 16 of the close
pairs, and among the wider ones there is in
33 instances indication of proper motion.
It is the intention, when the work is com-
pleted, to publish a catalogue of these stars,
including about twenty new pairs which
Professor Hough has discovered since his
last list was issued.
A Study of the Drwing-worms of Several
Photographic Telescopes: Epwarp §.
KING.
In following a star with a photographie
telescope we must have for the period of
the exposure a clock the hour hand of
which will indicate the elapsed time on a
scale graduated to seconds or less. We
must have the equivalent of being able to
determine the time by measuring the posi-
tion of the hour hand with a micrometer.
If any periodic error occurs in the train
of the driving mechanism, causing the tele-
scope to be first in advance of, and then
Marcu 17, 1905.]
behind, its proper position, the stellar im-
ages will be elongated into lines having a
length dependent upon the amount of the
oscillation. If the telescope follows the
star only at one extremity of the oscilla-
tion, we shall have a series of images sepa-
rated by trails, or, if the rate of the tele-
scope is changed more, we shall have a trail
with dark knots appearing at regular inter-
vals. The number of the knots determines
the frequency of the oscillation, and almost
invariably indicates the driving-worm or
endless screw as the offending member.
Such a periodie error, as shown by slide
1, is present in nearly all telescopes driven
in this manner. This fact is not anything
new, but has been recognized for years.
The first example that I know of personally
occurred in 1888 with the Boyden thirteen-
inch telescope. In 1896 the director
asked me to determine the periodic error
of two of our photographic telescopes.
Several series of measures were made of
the eight-inch and the eleven-inch Draper
telescopes. The method was to view a
point of the tail-piece through a fixed mi-
eroscope fitted with a micrometer. After
each release of the detent by means of the
signals given by hand, the position of the
point was read and recorded. The reduc-
tion of these measures shows that the oscil-
lation for the eight-inch Draper telescope
was about 1 second, and for the eleven-inch
Draper telescope about 0.2 second. These
figures correspond to trails of less than
0.01 em. on the plate. Within a few years
Dr. Hartman has studied the periodic
error of the Potsdam refractor and pro-
vided a very ingenious method of correc-

and zoological nomenclature, and that the
use of a generic name in the one kingdom
did not debar its use in the other. The dif-
ferent branches of zoology have now become
so extended and specialized that the same rule
of divorce might well be extended to the dif-
ferent branches of zoology. Little, if any, con-
fusion could arise to ornithologists, or mam-
malogists, or ichthyologists, if a bird name,
a mammal name, or a fish name should have
eurrency for a genus of insects, or mollusks,
or crustaceans, or echinoderms, or in each of
these branches. If it could be agreed—and
I am aware of no opposition—that the same
generic name may hold good in different
branches of the animal kingdom, but must not
be used twice in the same branch (as in
vertebrates, for example), it would result in
the restoration of not a few familiar names
that have had to give way under the animal
kingdom priority rule, and lessen, if not quite
do away with the present incipient call for an
impracticable ‘ one-letier rule.’
5. The Authorily for Names.—lIt is diff-
cult to see the reason for Canon X XIX., which
appears not to be published in full in The
Condor. It is contrary to current usage and
to other modern codes, that the authority for
a name, given in manuscript on a museum
label, is to be cited as the proper authority
for such names when published by another
author, who supplies the description and as-
sumes the responsibility for the species. This
canon says: “If a writer ascribes one of his
species to some one else, we must take his
word for it. Thus the manuscript species of
Kuhl and Van Hasselt in the Museum of
Leyden, although printed by Cuvier and
Valenciennes, should be ascribed to Kuhl and
Van Hasselt.” This is not only a confusion of
responsibility, but is bibliographically mis-
leading, tending to throw the investigator off
the track in looking for the original descrip-
tion of the species. Unless the publishing
author endorses the supposed new species, he
simply ignores the manuscript name and takes
the responsibility for its suppression, just as
in the other case he takes the responsibility
for its publication and supplies the necessary
description. If the author of a manuscript

435
name supplies a description to accompany it,
which only rarely happens, and the publishing
author uses it as inedited manuscript, then
the author of the name is also the author of
the deseription and is to be cited as the au-
thority for the species. In the other case, the
name should be eited, in synonyny, as Cuvier
(ex Kuhl, MS.), and otherwise as simply
Cuvier. In the case of inedited matter, the
citation would be Kuhl (in Cuvier, ete.), and
otherwise as Kuhl. This, like the other points
eriticized above, is a singularly retrograde
step.

CURRENT NOTES ON METEOROLOGY.
METEOROLOGICAL RESULTS OF THE BLUE HILL
KITE WORK.
Tue meteorological work done at the Blue
Hill Observatory by: means of kites has so
often been alluded to in these ‘ Notes’ that no
comments on the value of this work are neces-
sary at this time. The latest publication in
this connection is a valuable report by H. H.
Clayton, entitled ‘The Diurnal and Annual
Periods of Temperature, Humidity and Wind
Velocity up to Four Kilometers in the Free
Air, and the Average Vertical Gradients of
these Elements at Blue Hill’ (Annals Astron.
Obs: Harv. Coll., UNIT. Pt. 1, 1904). Al-
though some of the results herein discussed
have already been brought forward in previous
publications by Mr. Rotch and Mr. Clayton,
the compact and careful summary now issued
will be welcomed as giving a definite and com-
plete presentation of the principal conclusions
which have been reached through the well-
known, extended and laborious series of scien-
tifie kite flights—a field of investigation in
which Blue Hill has taken a front rank.
A study of the sources of error in the in-
struments and methods precedes the discussion
of the results. Six possible sources of con-
stant error are recognized as influencing the
records, and also one source of error, not con-
stant, which arises from temporary local dif-
ferences of condition, and from the fact that
the kites do not rise vertically. A glance at
these preliminary pages will show with what
extreme care the observations have been treat-
434
ed before being employed in obtaining any
definite results.
of the sources of error must also bring up
many doubts concerning the accuracy of re-
sults obtained by observers who exercise less
eare. It may be noted that, in Mr. Clayton’s
opinion, the excessive temperature gradients,
greatly exceeding the adiabatic rate, which
have several times been referred to in various
publications, are probably due, for the most
part, to the fact that the observations in ques-
tion were not made simultaneously at the two
levels (p. 14). Temporary local differences of
temperature may also explain gradients which
exceed the adiabatic rate (p. 15).
The interest which attaches to all reliable
meteorological data obtained in the free air is’
so great as to warrant the inclusion, in the
pages of Science, of the following summary
of the most important points contained in
Mr. Clayton’s report.
Diurnal Period of Temperature at Different
Heights—On several occasions observations
were obtained during many hours at heights
of about 3 kms., but there was no evidence
of any change of temperature due to a diurnal
period. On June 18-19, 1900, for example,
the temperature at a height of 2,900 ms. was
recorded at intervals throughout twenty-four
hours, and although there was a general fall
under the influence of some general atmos-
pheric. change, there was no appreciable di-
urnal period (Fig. 3, p. 16), in spite of the
fact that there were only a few cirrus clouds
to obscure a small portion of the sky. At
1 km. there is a diurnal period of tempera-
ture, as is evidenced by numerous records, but
with a tendency to a secondary maximum at
night as well as by day. A marked feature
is also a sudden fall of temperature after sun-
rise (about 9 A.M. in summer), the evidence
from the movements of the kites at this time
being to the effect that the diurnal convec-
tional currents from the ground reach the
kites then. This ‘chilling’ of the air at a
height of about 1 km. is explained by Mr.
Clayton as due to the rise of the ascending
currents, on account of their inertia, to an
altitude greater than their point of equilib-
rium. ‘The ascending air is cooled by adia-
SCIENCE.
Mr. Clayton’s thorough study -
[N.S. Vou. XXI. No. 5332
patie expansion below the temperature of the
air into which it penetrates; hence, at the tops
of convectional currents of this kind, rising
irom the ground, there ought to be a belt of
chilled air, above which there must be a higher
temperature. Such an inverted temperature
gradient is usually found above cumulus
clouds. The diurnal change of temperature
at the greatest altitude reached by the ascend-
ing currents must, therefore, be the opposite
of that at the ground, z. e¢., the temperature is
lower by day than by night. The records of
May 1, 1902, show clearly that an inversion of
tle march of the diurnal temperature does
occur at the top of convectional currents rising
from the warm ground (Fig. 4, p. 20), for
while at 500 and 1,000 ms. the afternoon maxi-
mum is well marked, the temperature curve
becomes inverted at 1,230 ms. At 2,000 ms.
there is no perceptible diurnal period. This
cooling at the tops of convectional currents
begins nearer the earth’s surface early in the
11orning, and reaches a maximum altitude
about the warmest part of the day. The di-
urnal period of temperature at different
heights is graphically summarized in Fig. 5
(p. 25), and verbally, on p. 29.
The Diurnal Period of Relative Humidity
at Different Heights—In general, the diurnal
period in relative humidity is the inverse of
that of the temperature at all levels up to and
including 1,500 meters.
The Diurnal Period in Wind Velocity at
Different Heights—Mr. Clayton finds the
well-known explanation, given by Espy and
Képpen, of the diurnal variation in wind
velocity only a partial one, for at night the
air from 300 to 1,000 ms. above sea level does
not merely resume a velocity of movement
proportional to its height, but increases in
velocity until its movement is more rapid
than that of the air strata above or below the
given level. Some other forces must, in Mr.
Clayton’s opinion, be called into play besides
the retardation of the upper currents by as- —
cending currents from below. It is suggested
that, as the atmosphere is trying to maintain
a mean yelocity of flow having a constant —
value for the vertical section above any given ~
point on the earth, if in any given part of ;
Marcu 17, 1905.]
the section the velocity is diminished, the air
must flow faster in some other portion. This
theory seems to explain satisfactorily the in-
creased velocity between 3800 and 700 ms. at
night. The retardation of the air between
900 and 700 meters during the day, due to
ascending currents, results in an increased
velocity near the ground, and, as this is not
sufficient compensation, also in the section of
air between 1,000 and 2,000 meters. Hence,
at the latter height, the velocity has a maxi-
mum by day and a minimum by night, as is
the case at the ground.
Vertical Gradients of Temperature, Humid-
ity and Wind Velocity—At night the tem-
perature rises with increase of altitude up to
about 500 meters, and not until a height of
over 1,000 meters is reached is the tempera-
ture in the free air as low as at the ground.
During the day the temperature decreases
with altitude nearly at the adiabatic rate for
dry air up to 500 meters. Above that height
the rate decreases, probably owing to frequent
inverted gradients and to cloud formation.
Between 500 and 1,500 meters the temperature
decreases more rapidly by night than by day.
The decrease is most rapid in summer and
least in winter. During the day the rate of
decrease diminishes to 2,000 meters, and then
increases again. From 0 to 500 meters the
rate is at a maximum by day and a minimum
by night, but between 1,000 and 1,500 meters
this condition is reversed, owing to the inver-
sion of the diurnal period. An important
point, noted on page 50, concerns the mean
vertical temperature gradient, about which
much has been written. Gradients which are
the mean of two opposing conditions may not
occur at all. The most frequent gradients
which actually occur are (J.) an increase of
temperature with increase of altitude, between
+0°.1 and +1°.0 (C.) per 100 meters, and
(II.) the adiabatic gradient, 1°.0 (C.) per 100
meters. Some gradients exceeding the adia-
batie rate have been observed, chiefly between
9 a.M.-and 3. p.m. On the average, the rela-
tive humidity increases during the day up to
about 1,000 meters, and then decreases to
about 2,500 meters. During the night the
relative humidity diminishes rapidly up to a
SCIENCE. 435
height of 500 meters, and then more slowly,
to a height of about 2,500 meters. Above
2,500 meters the relative humidity increases
slowly again. There is a very rapid increase
of wind velocity at night to a maximum at
500 meters, a slight decrease between 500 and
1,000 meters, and then an increase becoming
more rapid with increasing height. There is
a relatively rapid increase of wind velocity by
day from the ground to 500 meters; a slower
decrease from 500 to 1,500 meters, and almost
no change from 1,500 to 2,000 meters.

MEETING OF THE BRITISH ASSOCIATION
IN SOUTH AFRICA.
Tue British Association will hold its meet-
ing this year in South Africa. In these ex-
ceptional circumstances, the general officers of
the association requested the council to ap-
point a strong committee to cooperate with
them in carrying out the necessary arrange-
ments. ‘This ‘South African Committee’ has
held frequent sittings; and its work is so far
advanced that the London Times is now able
to make the following announcements:
Although the annual circular and program
have not yet been issued, pending the receipt
of information from South Africa, many mem-
bers have already intimated their intention of
being present at the meeting. The ‘ official
party’ of guests invited by the central execu-
tive committee at Cape Town, and nominated
in the first instance by the council of the
association, numbers upwards of 150 persons,
comprising members of the council, past and
present general officers and sectional presi-
dents, the present sectional officers, and a cer-
tain proportion of the leading members of each
section. To this list has yet to be added, on
the nomination of the organizing committee,
the names of representative foreign and
colonial men of science, the total number of
the official party being restricted to two hun-
dred, including the local officials. It is hoped,
however, that many other members of the asso-
ciation will also attend the meeting.
The presidents-elect of the various sections
are as follows:
436
A. Mathematical and Physical Science.—Pro-
fessor A. R. Forsyth, M.A., Se.D., F.R.S.
B. Chemistry.—T. Beilby.
C. Geology—Professor H. A. Miers, M.A., D.Sc.,
F.R.S.
D. Zoology—G. A. Boulenger, F.R.S.
E. Geography.—Admiral Sir W. J. L. Wharton,
K.C.B., F.R.S.
F. Economie Science and Statistics—Rev. W.
Cunningham, D.D., D.Se.
G. Engineering.—Colonel Sir Colin Scott-Mon-
erieff, G.C.S.I., K.C.M.G., R.E.
H. Anthropology—aA. C. Haddon, M.A., ScD.,
F.R.S.
I. Physiology—Colonel D. Bruce, M.B., F.R.S.
K. Botany.—Harold Wager, F.R.S.
L. Educational Science—Sir Richard C. Jebb,
Litt.D., M.P.
The vice-president, recorders and secretaries
of the eleven sections have also now been ap-
pointed.
In view of the numerous towns to be visited
by the association, and in which lectures or
addresses will be given, the number of lecturers
appointed is much larger than usual. The list
of these, as at present arranged, is as follows:
Cape Town.—Professor Poulton, on Burchell’s
work in South Africa; and Mr. C. V. Boys, on a
subject in physics.
Durban.—Mr. F. Soddy, on radioactivity.
Maritzburg.—Professor Arnold, on compounds
of steel.
Johannesburg.—Professor Ayrton, on distribu-
tion of power; Professor Porter, on mining; and
Mr. G. W. Lamplugh, on the geology of the
Victoria Falls.
Pretoria (or possibly Bulawayo).—Mr. Shipley,
on a subject in zoology.
Bloemfontein.—Mr, Hinks, on a subject in as-
tronomy.
Kimberley.—Sir William Crookes, on diamonds.
As the wish has been conveyed to the council
from South Africa that a few competent in-
vestigators should be selected to deliver ad-
dresses dealing with local problems of which
they possess special knowledge, a geologist, a
bacteriologist and an archeologist have been
invited to undertake this work, involving in
two cases special missions in advance of the
main party. Whilst Colonel Bruce, F.R.S.,

G. W. Lamplugh (by the courtesy of the Board
of Education) will be enabled to investigate
certain features in the geology of the Victoria
Falls, particularly as regards the origin and
structure of the canon; and Mr. D. R. Mac-
Iver, who is at present exploring in Nubia,
will proceed in March to Rhodes in order to
examine and report on the ancient ruins at
Zimbabwe and also Inyanga.
Most of the officials and other members of
the association will leave Southampton on
July 29 by the Union-Castle mail-steamer
Saxon, and arrive at Cape Town on August
15, the opening day of the meeting; but a
considerable number will start from South-
ampton on the previous Saturday, either by
the ordinary mail-boat or by the intermediate
steamer sailing on that date.
The sectional meetings will be held at Cape
Town (three days) and Johannesburg (three
days). Between the inaugural meeting at the
former and the concluding meeting at the
latter town opportunities will be offered to
members to visit the Natal battlefields and
other places of interest. Subsequently a party
will be made up to proceed to the Victoria
Falls, Zambesi; and, should a sufficient num-
ber of members register their names, a special
steamer will be chartered for the voyage home,
via Beira, by the East Coast route, as an alter-
native to the return through Cape Town by
the West Coast route. Thus all the colonies
and Rhodesia will be visited by the associa-
tion. The tour will last seventy days via
Cape Town, or a week longer vid Beira (all
sea), leaving Southampton on July 29, and re-
turning thither on October 7 or 14.
A central executive committee has been con-
stituted at Cape Town, with Sir David Gill
as chairman and Dr. Gilchrist as secretary,
while local committees have been formed at
Johannesburg and other important centers.
Professor G. H. Darwin, F.R.S., is the
president-elect ; and among the vice-presidents-
elect are the following: The Right Hon. Lord
Milner, the Hon. Sir Walter Hely-Hutchinson,
Sir Henry McCallum, the Hon. Sir Arthur
Lawley, Sir H. J. Goold-Adams, Sir David
Gill and Sir Charles Metealfe.

others have taken a prominent part in the
initial work. The South African Association
for the Advancement of Science is cordially
cooperating in the local organization, and will
join with the British Association in attending
the meeting.
The aim of the council has been to secure
the attendance of a representative body of
British men of science, including specialists
in various lines of investigation; and that,
along with the generous support of the people
and authorities in South Africa, should go far
to insure the success of the meeting and to
stimulate local scientific interest and research.

R. I., Brown University becomes the recipient
of the bulk of the Littlefield estate, estimated
at $500,000. The will provides that the cor-
poration shall apply the money as it sees fit,
except that $100,000 shall be used for the
establishment of the George L. Littlefield pro-
fessorship of American history.
By the will of William F. Milton, of New

THE regents of the University of Nebraska
have recently voted $50,000 for the erection of
the first wing of a building to accommodate
the department of geology and the State Mu-

present is so overcrowded and is so subject to
loss by fire that the curator has boxed and
removed fifty tons of material during the past
school year. This has been lowered for safe
keeping in an unused steam tunnel running
under the campus. In the hope and full ex-
pectation that the legislature of Nebraska will
act favorably upon this recommendation of
the regents, the Honorable Charles H. Morrill,
founder and patron of the Morrill geological
expeditions of the University of Nebraska, has
offered the department an additional thousand
dollars annually with which to pursue geolog-
ical investigations both within and beyond the

The address of the retiring vice-presi-
dent of Section H, Marshall H. Saville,
entitled ‘Mexican and Central American
Archeology,’ was delivered Friday after-
noon.
WEDNESDAY, DECEMBER 28.
The afternoon session began with the
paper on ‘Anthropometric Work at the St.
Louis Exposition: (a) Sense Tests of Vari-
442
ous Races, (b) Physical Measurements of
Philippine Groups,’ by R. 8. Woodworth
and Frank G. Bruner.
Over a thousand individuals, belonging
to twenty-two groups and nine races, were
measured, and most of these were subjected
also to sensory and mental tests. Among
the results may be mentioned: the superi-
ority of some groups, especially the Fili-
pino, in eyesight, and the inferiority of
others, the Ainu, Negrito and African
pigmy ; the presence of red-green blindness
among Filipinos to about the same extent
as among whites; the general inferiority of
other. races to the white in fineness of color
perception, but no special deficiency in per-
ception of the violet end of the spectrum.
A comparison of the height, cephalic,
facial and other indices of several Filipino
groups was obtained which showed that, on
the whole, the population of the islands is
remarkably uniform in physical measure-
ments.
After the presentation of Professor
Woodworth’s paper, the society adjourned
to attend the discussion on ‘Mutation
Theory of Evolution,’ in Dental Hall.
THURSDAY, DECEMBER 29.
The meeting was opened by the vice-
president, Walter Hough. The first paper
was, ‘The Story of a Shield,’ by James
Mooney.
Professor Mooney said in part:
In the old days all men between twenty-
five and fifty years of age, in the Kiowa
tribe, had shields. They were the personal
property of the mounted warriors and, on
the plains, this object was the most prized
possession of the Indians. When a warrior
was killed his shield was usually buried
with him. Each shield had a distinct
origin, although a number might be made
of the same form and from the same dream.
Out of 300 Kiowa shields there might have
SCIENCE.
[N.S. Vor. XXI. No. 534.
been 50 shield origins. One man might
make many shields, which came from a
dream, and the wearers would form a small
elan-like body. One of the old shields was
that of the buffalo. Its origin was from the
buffalo and it had buffalo medicine. It
was worn by the medicine men who knew
how to eure arrow and gun-shot wounds.
As shields were used in warfare, they could
be made for no other purpose.
The bird shield was of special interest
to the speaker, as he had been more closely
associated with it than with any other. A
story was related of a Kiowa boy who en-
deavored to get medicine from a water
monster formed like a horned alligator.
He approached a pool and looked into the
water. He heard the voice of a boy who
finally invited him to his father’s tent.
The young man went in. He saw seven
men seated against the wall of the tent.
These men turned into birds. Each had
a shield which was fastened above his
head. They told the young man that they
had heard his longings and that they would
give him medicine. They would give him
a shield. They also gave him nine songs.
The shrike gave him the song that was to
be sung when he went into battle. The
call of each bird was to be used in battle
in connection with the proper shield and
accompanying the song of the particular
bird.
A model of the original bird shield was
shown. It had a rainbow, the sunlight and
dots representing the ashes thrown down
by the old men in the sky. These objects
were considered to be great medicine. The
inside of the shield contained the secret
medicine known only to the owner. This
was revealed at the moment that the owner
made a charge in battle. Each shield had
a number of taboos, the breaking of which
was a misfortune; there were, however,
many ways of propitiation and thereby
overcoming the harm that had been done.

Themistology. Epwarp LInpsay.
An important branch of the study of
man is the science of institutions. Of hu-
man institutions one of the most important
is law. Law has been defined as any re-
straint of the individual by the group
which is backed by physical force. This
overlooks the idea of rules for the adjust-
ment between individuals of the rights in-
hering in them by reason of their status in
the social organization, which are the
ereater part of law. Different terms for
these two concepts are needed; the first
may be called Nomos, the second Themis.
The science of themistology would investi-
gate that portion of the law of all peoples
embraced within the concept Themis. Eth-
nologists have determined that there are
various forms of social organization which
have existed at different periods and among
widely separated groups, and from the
study of these have distinguished succes-
sive stages in the evolution of society. In
the same way we should examine other
themal concepts, as marriage in its various
forms, contract, ete., and, after collecting
all available facts, study them and deter-
mine whether there are ideas recurring
generally among different groups which
pass through a stated course of develop-
ment. By this use of the scientific method
may be obtained a true science of law.
This subject is urged on the attention of
anthropologists because the facts must be
largely collected among primitive peoples.
To distinguish between the two different
classes of facts included under the term
law, however, is essential to an intelligent
collecting of material.

ing results concerning the weight of the

Mr. W. W. Newell ealled attention to
the presence of Miss Mary Speers, a lady
who had collected negro songs. He asked
that she be allowed to sing some of these
southern melodies. In preparing these
songs she demonstrated the need of study-
ing the tone of the singer-as well as the
notes of the song. Four selections were
rendered.
Superstitions of School Children. Win
S. Monroe.
Mr. Monroe has been collecting the su-
perstitions and games of children for sey-
eral years. One thousand children were
questioned concerning good and bad luck.
The predominating good luck charm among
the girls was a pin; among the boys, a
horseshoe. The number of superstitions
among the members of both sexes at differ-
ent ages were noted and tabulated. These
consisted of arrival of company supersti-
tions of which there were twenty-three;
those concerning the weather, love and
marriage, sickness and death, and the num-
ber thirteen. He found that the thirteen
superstition does not figure to any extent
and was not found in children under ten
years of age.
The Tale of Three Wishes. Wiu1amM W.

given to the devil. When he is being ear-
ried away he begs the devil to pick a pear
for him. He is so insistent that the devil
finally climbs the tree to obtain the fruit.
One of the wishes that the man had made
was to the effect that any one caught steal-
ing his fruit would have to stay in the tree;
thus he had the devil in his power. A
second time he gets the devil into his purse

in the form of a'ten-cent piece. In thus
using his wishes the man succeeded in keep-

This tale was compared with other wish-
stories in which similar details appear.
Influence of the Sun on the People of the
Hopi Pueblos. J. WAuTER. FEWKES.
The epitome of the history of the Pueblos
is shown by their ruins.
The earliest forms were on the plains.
The second period brought them to the base
of the mesas, the third and last to the level
tops of the table lands.
The inclination of the house groups on
the mesa tops is in two directions—toward
the highest point, to obtain the greatest
security possible, and on exposures where
the maximum sunlight may be obtained.
The houses ofttimes form two lines, the
direction being northeast and southwest.
This peculiarity was first noted by Cosmos
Mindeleff. The reason for this uniformity
was not estheticism but the position of the
sun. This occurs in all of the Hopi Pueb-
los but two. There are three specific causes
for this: (1) the growth of the family, (2)
the growth of the house group, (3) the
position of the sun.
Among the Pueblos there are only two
places where additions to the paternal
home can be made, that is on the northeast
and southwest of the nucleus or home
group. The reason for this is that the
additions must not cut off the sun from the
house already built. These additions to
the home continue as daughters are born
and marry.
When a new clan comes to a pueblo it is
given a new position which will not conflict
with the sun supply of the first group.
The growth of these clan houses is a cel-
lular one in which the family is the initial
cell. This explains the form of most of
the modern pueblos. Some of these are
rectangular, which is the form of many of
SCIENCE.

the old ones. This may be explained by
the fact that a number of clans partici-
pated in the work of buwilding—both in
planning and in earrying out the details
of construction, in which ease the form of
the town was probably prearranged. Even
in this form of pueblo the terraces and
door entrances were usually toward the
sun.
The clans have been a great factor in the
formation of the house groups. They are
responsible for whatever peculiar features
may be in evidence in both the ancient and
the modern pueblos. The clan problem is
a most interesting one. Its solution can be
accomplished in no way save by a thorough
study of the migrations cf-each, and its
relationship to the pueblo. It is one of the
most interesting phases of anthro-geog-
raphy or psycho-geography in the scuth-
west.

His latest work has been the preparation
of changes in and amendments to the bills
that have been drawn up for the protec-
tion of remains on the public domain. This
work enabled Professor Hewett to handle
the subject in a very comprehensible way.
The groups of ruins were described, the
labor expended .in each, and what should
be done in the way of preserving them for
future scientific work. The various bills
for the preservation of ruins were ex-
plained, and the objectionable features of
each pointed out. Reports of the commis-
sioner of the general land office, and a
monograph by the speaker were given to
members of the section in order that a bet-
ter comprehension of existing conditions
might be obtained.

Prehistoric Surgery: A Neolithic Survival.
GEORGE GRANT MacCurpy.
This paper dealt with a certain type of
neolithic surgery having certain points in
common with trepanning, and which has
been brought to light during the past
decade. The type oceurs in France over
a limited area lying to the north of Paris
between the Seine and the Oise. The ci-
catrice is usually in the shape of a T, the
antero-posterior branch following the line
of the sagittal suture; and the transverse
branch, encountered in the region of the
obelion, descending on either side to a point
back of the parietal protuberances. In
addition to the T-shaped lesion, one skull
was marked by two oval perforations, one
quite large, and two pits large enough to
lodge the tip of the finger. The eight or
nine specimens already described are all
from prehistoric sepultures known as dol-
mens. In the opinion of Professor Man-
ouvrier the lesions were produced by cau-
terization, an opinion which was recently

Section I is in some respects ideally con-
stituted. It has a smaller body of experts
in its membership who plan its programs
and work out its policy. The larger num-
ber of members represent business experi-
ence and practical social effort. It thus
combines in its programs the scientifie dis-
cussion and methods of the expert with the
results of well-considered experience in
social and economic affairs. This year’s
program was well supplied with papers:
representing both phases of interest.
Two joint sessions were held, one with —
Section D for hearing a paper by Professor —
A. E. Outerbridge, Jr., on ‘Specialization
in Manufactures,’ and one with the Society
for the Promotion of Agricultural Science,
to hear the memorial by Professor W. R.

in the history of the section. Out of the
twenty-three papers twenty were read in
person by the authors. The attendance on
the part of the public varied from thirty-
five at the first session to seventy-five at the
last session. Five different sessions were
held, including one afternoon session de-
voted to the address of the retiring vice-

SESSION ON ECONOMIC QUESTIONS.
The Basis of Economics as an Exact
Science. Professor Srimon NEWwcoMB,
Washington, D. C.
One of the first things to strike us in the
effort to apply scientific methods to eco-
nomics is the absence of nomenclature. We
notice, in the first place, that there is no
name for the organized system of economic
phenomena. Herbert Spencer has used the
term ‘social organism,’ but the objection to
that is that it includes more than is neces-
sary. It embraces all phenomena which
are social, but there are social phenomena
which do not strictly belong to the economic
order or which relate so indirectly to it as
to be negligible factors in the consideration
of economic questions.
Another phase of defective definition

may be mentioned. I refer to the fact that
there is no name for that portion of wealth
which is not capital. Marshall makes use
of the inconvenient term of ‘wealth of the
first order.’
Referring to the economic order as a
whole, we notice, to begin with, that it is a
unified system, in which the parts are re-
lated as means and ends. In economies
these terms, means and ends, take the place
of the correlated terms cause and effect in
the physical order. That is, the relation
of means and ends in economics corresponds
to the relation of cause and effect in phys-
ics. In the economic order capital is
means. The problem, then, is to find the
relation of capital means to economic ends.
We must study from ends to means and
from means to ends according as the one
or the other inquiry may be necessary to
establish the causal relation which is the
business of science to ascertain.
Now, as to the method of inquiry. In
this procedure we haye to distinguish be-
tween machinery which is necessary for
production and auxiliary means to an end.
The machinery necessary for production is,
of course, capital in its essential character.
The auxiliary means to ends which capital
serves to reach is money. But money, im-
portant as it is in its auxiliary function,
adds nothing to the power of the machine.
Knowledge or direction is needed as an-
other auxiliary in the organization of the
means to ends of production.
Socialism overlooks the necessity for the
means of production, and seems to be based
on the omission of this mediating factor
between man’s wants and his ends. The
socialist is like the man who walks to the
edge of a precipice and propeses to proceed
even at the risk of losing his hfe rather
than to build a bridge to pass from one
precipice to another.
How far can economics be made an ex-
448
act science? It is often said that this sub-
ject depends too much on the vagaries of
human nature to bring the economic proec-
esses within the category of exactness,
This is true to some extent. We all know
that the corn and the cotton crops, for
instance, are uncertain quantities. We
know that these affect economic activities
to such an extent as to require constant
readjustment. On the other hand, it is true
that we know just about how a shortage in
the corn crop or a marked enlargement in
the cotton crop is going to affect the actions
of persons interested. We know how the
economic order in general, and how the
divisions of enterprises directly affected are
going to behave, other things being equal,
under the changed conditions in the crop
yield. It may, therefore, be said that
there is a far greater degree of exactness
attainable in measuring the force of eco-
nomie processess than is usually assumed
in the criticism based upon the assumptions
of the vagaries of human nature.
We may, therefore, be exact in the in-
vestigation of the action of causes. For
example, we can study with a remarkable
degree of accuracy the influence of the in-
crease of currency upon prices.
We may also maxe the comparative con-
dition of the masses in different countries
a subject of exact study. Take the five
different nationalities of Russia, Austria,
France, England and the United States.
These are given in the order of the wage
income, let us assume. The cost of sub-
sistence is about the same in all of them,
but wages are lower in the order given.
Why is this the case? There must be some
exact causes, and the problem is to deter-
mine what these laws are.
Another phase of the subject of method
on the action of causes appears in the ap-
plication of mathematical methods or prin-
ciples to the study of economies. Jevons,
for instance, applied mathematical methods

to the determination of the law of marginal
utility thirty or more years ago, and the
principle has been extensively used and
developed in numerous treatises since then.
The law of supply and demand has like-
wise been treated mathematically by Mar-
shall. -
Returning again to the study of the con-
dition of the masses, the main question is
to find the causes of inequality of income.
Methods hitherto pursued have generally
lacked comprehensiveness. We may, how-
ever, assume that these inequalities are de-
termined by the law of supply and demand
and by a law of distribution growing out
of the law of supply and demand.
One of the first things we notice is the
creat difference in apparently similar men.
The captain of an Atlantie liner, for in-
stance, who has millions of dollars of value
intrusted to his care, together with thou-
sands of lives, may in all outward respects
and in mental qualities be apparently the
equal of one whose judgment and practical
capacity could in no wise be intrusted with
so responsible a task as that of bringing a
vessel across the Atlantic in safety.
The first problem which we may propose
for ourselves in this field is that of the
effect of supply and demand on the distri-
bution of income. In books three and four
of my ‘Principles of Political Economy,’
published twenty years ago, I sought to
work out this problem in its twofold as-
pects: (1) From the standpoint of the —
productive process, and (2) from the
standpoint of the societary circulation or
the monetary movement. The chief diffi-
culty in the solution of this problem lies
in the numerous complications of the eco-
nomic order as represented in changes and
the multifarious causes at work. The
problem may be simplified in statement
by being represented in graphical form.
We may, for instance, take the loaf of
bread as a product and follow it back
Marcu 24, 1905.)
through the chain of incipient factors, be-
ginning with the farm on which the wheat
is produced as the first step; second, Chi-
cago as a wheat market; third, the baker;
fourth, the house of the consumer. The
productive process may be said to termi-
- nate, temporarily, at any rate, in the house,
extending from the farm of the producer
to the house of the consumer. On the con-
trary, the societary process, or the mone-
tary flow, extends from the house of the
consumer back through the baker and
through the wheat market to the farm
where production began. These two cur-
rents represent an exact quantity, in the
one ease of goods, and in the other ease of
money. They move in opposing direc-
tions, and in this respect are analogous to
the two opposing currents acting simul-
taneously, as represented in electrical
theory.
There are various other causal factors to
be brought into the study of this relation,
ineluding such factors as the mechanic,
who purchases from the hardware store, the
hardware store purchasing from the tool
factory, the tool shop purchasing from the
rolling mill, and the rolling mill from the
mine; but along each of those connections
the two currents, productive and cireula-
tory, are in active operation, and all of
these factors are directly or indirectly con-
nected with another factor—the govern-
ment.
This representation may seem at first
glance to be complicated by reason of the
numerous currents represented in the two-
fold process, the productive and the circu-
latory. Could the conclusions arrived at
in this method be put in such a form as to
have the community accept them? Eeo-
nomic conclusions are not easily accepted
by the community in general. Why is this
so? One reason—possibly the main rea-
son—is that economists have failed to dis-
tinguish between means and ends. ‘To the
SCIENCE.
449
economist ends, rather than means, are im-
portant all the time. The economist, as a
rule, has laid so much emphasis on means as
to diffuse the sum total of impression made
upon the mind of the community. Never-
theless, the individual member of the com-
munity and the community as a whole are
interested in results, in ends, in income
rather than in outlay, but the income in
which they are interested is not the mone-
tary income, but real income. I may
illustrate this by supposing that in case of
our civil war, the policy of the northern
states toward the south had allowed ex-
ports to be made unhindered, but had pro-
hibited all imports except gold and silver.
What would the effect have been? The
great majority of people would at first
hand say that it would have enabled the
confederate states to command the control
of all utilities they desired, and thus
worked exactly contrary to the blockading
polhey. But would that have been the
ease? We see that it would not, as soon
as we realize that gold and silver are means
and not ends. If the prohibition of im-
ports of economic goods, except gold and
silver, had been carried out, the productive
process would have been interrupted and
the starving-out policy have gone on sub-
stantially as it did under the blockade.
This illustrates the relative importance of
the productive process as distinguished
from the monetary movement.
Workings of the Anthracite Coal Strike
Agreement. Ww. H. Taytor, St. Clair
Coal Company, Scranton, Pa.
This strike was inaugurated May 12,
1902. Five months later President Roose-
velt appointed the commission ‘“‘to inquire
into, consider and pass upon the questions
in controversy in connection with the
strike in the anthracite region, and the
causes out of which the controversies arose.
By the action you recommend, which the
450
parties in interest have in advance con-
sented to abide by, you will endeavor to
establish the relations between the em-
ployers and the wage workers in the an-
thracite field, on a just and permanent
basis, and, as far as possible, to do away
with any causes for the reoceurrences of
such difficulties as those which you have
been called upon to settle.’’ Meanwhile
the strikers returned to work. Five
months later, March 18, 1903, the commis-
sion made its report to the president. The
report says: ‘‘The occasion of the strike of
1902 was the demand of the United Mine
Workers of America for an increase in
wages, a decrease in time, and the payment
for coal by weight wherever practicable;
and where not, then paid by car. The
eause lies deeper than the occasion, and is
to be found in the desire for the recognition
by the operators of the miners’ union. The
great strike of 1900 which resulted in an
advance of ten per cent. in the wages paid
to all classes of mine workers, did not leave
either miners or operators in a satisfied
state of mind, for both agree that since the
settlement of 1900 there have been in-
creased sensitiveness and irritation in the
mining districts as compared with the
previous twenty-five years or more.’’
Every coal mining company finds, as to
the discipline, that there is generally a de-
cided change for the worse; which, al-
though it is known to exist, and is shown
in many ways, is still difficult to define.
Formerly employees seemed to be willing
to turn their hand to anything that would
further the work of the company, but now-
adays if a man is asked to do a little out-
side of his regular line, he refuses to do
it or does it grudgingly, telling the foreman ~
that it is not his job.
The feeling of sensitiveness and irrita-
tion to which the commission referred, has
not lessened, but, on the contrary, is a
smouldering fire, which breaks forth at the

same months in 1899 and 1900.’’

The Present Status of Railroading in
China. CHuune Hur Wane, Yale Uni-
versity Law School.
The present method of railroading in
China constitutes one of the prime factors
in the shaping of the future destiny of that
country. While other countries are now
lined with networks of railways, we find
Marcu 24, 1905.]
that in China the ‘iron road’ has not yet
become a household word. Foreign ob-
servers who have but a superficial view of
the subject do not hesitate to attribute the
cause of this to the superstition, ignorance,
prejudice, and what not, of the Chinese
people. In my opinion there are two
fundamental causes back of this, the one
financial and the other political. If we
bear in mind that the construction of every
mile of railroad costs upwards of $10,000,
we can well imagine the financial diffi-
culties with which we are confronted in the
construction of a complete system of rail-
roads. Moreover, the heavy indemnities
and exactions which have been wrung from
us by the foreign powers at different
periods since the Opium War of 1841 up
to the Boxer uprising of 1900 have almost
exhausted our resources, and have con-
sequently increased the difficulties of our
problem. Again, railroading is more than
a mere economic undertaking; it has polit-
ical as well as strategic importance. The
main objection which has been urged by
the high officials against the adoption of
railroads is that as long as China is not
strong enough to defend herself against
foreign aggressions, the presence of rail-
ways would be a constant menace to the
safety of the country. If we read the
Chinese state papers on the subject, we shall
notice that the problem has been somewhat
overestimated in its political and strategic
importance, and underestimated in its eco-
nomie and commercial aspects.
To Li Hung Chang is usually given the
eredit for the construction of the first
permanent railway in China in connection
with the Kiping coal mines, eighty-four
miles northeast of Tientsin; but the credit.
is justly due to a subordinate official, Mr.
Tong King Shing, the pioneer of the intro-
duction of modern improvements into
China.

the idea of constructing railroads exclu-
sively with Chinese capital was abandoned
as being impracticable, and in March of
that year an Imperial Edict was issued en-
couraging the construction of railroads, and
in October, an official of high rank, Sheng
Sun Hawai, was appointed Director-Gen-
eral of Railroads with full power to raise
foreign loans. This was the beginning of
the period of ‘concessions.’
Within the past few years ‘railroad con-
cessions’ covering about 5,000 miles of rail-
way lines have been granted to different
syndicates, the largest of which is the
Belgian. These ‘concessions’ provide that
the ownership in the railways ultimately
reverts to the Chinese government. Con-
cessions are really contracts between the
native company of Chinese railways and
the foreign syndicates.
Can the South Manufacture Her Own
Cotton? CuarutEes Lee Raper, Univer-
sity of North Carolina.
Slavery was a decided hindrance to the
highest industrial development, just as the
free negro and the free negro’s ghost in
politics are obstacles to present industrial
progress.
The new south is not largely a product
of outside energy and eapital, but is a
revival and continuation of the old life;
she is a product of the ability of the south-
ern white man working under new condi-
tions. Though the new south is still far
behind the north in wealth and industrial
activity, the first twenty years of her life
saw more remarkable progress than any
other section of this extensive country.
General statistics are not all the evidence
that goes to the support of the conviction
that this section can become the world
center of the manufacture of cotton goods.
There is much in the general situation to
which statistics ean not give adequate ex-
pression. Climate, lack cf damaging frost,
452
creat water power and its freedom from
ice, and the cheapness of hcusing, clothing
and feeding the operatives, are all in favor
of this view. The specific facts of cotton
manufacture during the last twenty-four
years show that in 1880 the southern states
had less than 700,000 cotton spindles and
about $20,000,000 invested in ectton fae-
tories. To-day they have about 8,000,000
spindles, or more than eleven times as many
as in 1880. To-day they have almost $200,-
000,000 invested in factories, or ten times
as much as they had twenty-four years ago.
The greatest need of the present is the
direct sale of the products of the cotton
mill to consuming markets. This is grad-
ually being supplied, and with it the com-
plete chain of economie production—the
farmer, the manufacturer, the carrier and
the merchant—will be primarily in control
of the section of the country which is the
source of the raw material.
SFSSION ON EDUCATION AND SOCIAL SCIENCE.
Ameliorative, Preventive and Constructive
Social Work: and the Ideal Training for
Social Workers. Mrs. ANNA GARLIN
Spencer, New York School of Philan-
thropy.
Social service and social work mean, first,
a synthesis of that which is connated in
the four basic institutions of society, the
home, the school, the church and the state.
Social service has in it something of the
religious appeal to grow better and
stronger, however difficult the growth may
be. It has much of charity’s special
quality of devotion to those whose personal
or social condition makes it most hard for
them to live a truly human life. It has some-
thing of that dependence upon the organ-
ized whole of sceiety which has given the
modern state its functions of charity, edu-
cation and publie enlightenment through
free public benefits. It has much of that
spirit of moral reform which i: forever

blazing out in holy passion of rebuke
against tyranny of the weak by the strong.
It has, most of all, a giant share of that new
impulse in education which demands for
each child ‘the best development society
ean afford.’
The supreme distinction of modern social
service lies in its fundamental ideals and
the conscious purpose in its application of
those ideals. Those fundamentals are:
1. A belief in what Horace Mann ealled
the ‘infinite improvability of mankind,’ a
deep faith in the essential good quality of
human nature, a faith shared with all new
types of religious belief and the root of the
new education.
2. A belief that the race is not improved
solely or chiefly through its moral and
inteliectual elite (those capable of becom-
ing saints and sages and leaders), but that
the race is to be improved most completely
and surely by the upraise of the whole
mass of mankind. This is a faith in the
spiritual essence of democracy.
3. A belief that here and now society
has both the duty and the power to under-
take consciously, determinedly, systemat-
ically and hopefully this upraise of the
whole people, this demonstration in terms
of absolute democracy of the worth of all
human beings.
4. The belief that in order thus to grow
nobler, purer and stronger and happier
human beings in this wholesale fashion, so-
ciety must also work to make a better world
for the less fortunate and the weaker hu-
man beings now living.
5. The belief that since all the people,
especially ‘the least of these,’ are to be
lifted, society must hold itself responsible
for the welfare, the safety, the chance to
erow, the opportunity for education and
the ability to become self-supporting, of
every human being.
This then which we eall social service is
a synthetic appreciation and use of the
Marcu 24, 1905.]
new ideals of education, democracy and re-
ligion.
This synthetic function divides itself into
three main departments of social effort,
namely: (1) Ameliorative work, (2) pre-
ventive work, (3) constructive work.
In all great social activities the three de-
partments named work together and, there-
fore, the efficient organization of all chari-
table and reformatory forces is now indis-
pensable to social advance. The modern
warfare against disease is a perfect illus-
tration of the interaction of ameliorative,
preventive and constructive social work.
At least one third of all the persons who
require relief of a charitable nature do so
because of illness or physical disability.
Child Labor in Southern Mills. A. J. Mc-
Ketway, Assistant Secretary of the Na-
tional Child Labor Committee.
The southern cotton mill industry is
eentered in the Piedmont section of the
four cotton states that have mountains,
namely, North Carolina, South Carolina,
Georgia and Alabama. These are the
manufacturing states of the south.
This industry grew up in a night, and
old historic communities, holding fast to
their laissez faire doctrine, found them-
selves suddenly confronted with the prob-
lems for which they had no social experi-
ence and no legislative precedents. All
of our industries are infant industries. In
1880 there were 667,000 spindles in the
southern — states. In 1900 there were
7,000,000. In 1900 there were 412 cotton
manufacturing establishments. In Janu-
ary, 1904, there were 900, so that this state-
ment of their number is antiquated as
soon as it is made. The number has been
more than doubled in the last four years.
South Carolina stands next to Massa-
chusetts in the number of spindles, and
North Carolina is ahead of either in the
number of cotton mills, the mills being

smaller on the average than those of the
other two states mentioned. Considering
the shortness of the period of this revival
of manufacturing, the south as a whole has
acted with commendable promptness in
recognizing and seeking to remedy the evils
of child labor. The conditions of this
industry in the southern states to-day are
superior to those in either England or New
England and probably superior to those
that obtained when the industry was at its
best in New England and the operatives:
were the hardy children of the New Eng-
land soil. Despite the stories that have
been published in the magazines at so
much per column, it is a source of grati-
fication to know that people are buying
good clothes and good furniture and pic-
tures and books and stoves. The homes
of the people are three- and four-roomed
cottages, an infinite distance from the one-
roomed hut, and every cottage has an acre
plat of ground, for the garden, while the
pigs and the chickens and the cow have
quarters of their own. And there is all
of God’s out-of-doors for breathing space.
There is no night work at the mill, spinning
and weaving departments being evenly
balanced so that what is spun one day is
woven the next. The hours are long, how-
ever, from 6 in the morning to 6:30 at
night, with an intermission of forty min-
utes for dinner and a half holiday on
Saturday. And this brings up the fact
that there are too many young children in
that foree of a thousand workers and that
eleven hours and fifty minutes a day is too
long for any child to work in a mill, be the
work ever so light.
Work of the National Child Labor Com-
mittee. SamueL McCune Linpsay,

The permanent organization of the com-

1904, with a membership of forty-six per-
sons, constituting, perhaps, as remarkable
a group of varied industrial, financial, edu-
cational and social interests as was ever
brought together in America or in any
other country. Its membership now repre-
sents fourteen states and the District of
Columbia. The object is to secure as

and uniform enforcement of laws on this
subject throughout the union.

utive branches of the state and national
governments the results of the careful and

and remedial measures. The national
committee hopes to bring together the re-
sults of a larger parental responsibility,
the better development of the public school
system and the enactment of child labor
legislation in the several states and terri-
tories, and to coordinate these efforts so
that the evils of child labor may be eradi-
cated from the industrial system of
America.
The Press as an Educator. Wm. H.
Lyncu, Salem Publie School, Salem, Mo.
Jules Verne, the world-famous novelist,
wisely predicted that long before the
middle of the century novels or romances,
in volume form, would be supplanted by
newspapers. The newspaper of to-day,
great as it is, has yet before it a develop-
ment and_ potentiality for usefulness
scarcely imagined by its most far-seeing
and progressive directors.
It must be obvious to all thoughtful per-
sons that the newspaper may easily be
made the medium of imparting valuable
instruction in many departments of knowl-
edge on which the very latest text-books
are mere blanks. Take, fcr example, the
[N.8. Vou. XXI. No. 534.
experiments of Marconi in wireless teleg-
raphy, so minutely recorded and illustrated
in almost every newspaper. Would not
the study of the despatches, describing the
achievements of the great Italian, by boys
and girls sufficiently advanced to under-
stand them, be infinitely more profitable
than the dull book pages they are com-
pelled to read concerning the laying of the
first ocean cables so many years ago? To
this question there can be only one answer.
Take another current subject, with the
discussion of which the newspapers have
been filled in the most instructive and
luminous way—that of Venezuela. What
might not a competent teacher, with the
aid of the press, have accomplished in the
treatment of this question toward instilling
in the minds of his pupils correct under-
standing and conception of the Monroe
Doctrine, let us say, or a knowledge of the
Spanish-American republics generally and
our relations to them? Then there was a
ereat coal strike and the war between
Russia and Japan.
In the school books are a few meager
facts and dates, forgotten almost as soon
as they are learned, with respect to that
basic factor in the industrial world. With
the universal interest centered in the sub-
ject and the assistance of the newspaper,
the skillful teacher could have done more
to expand and inform the minds of all
those intrusted to his care than all the text-
book writers combined. Children should
not, of course, be permitted to read every-
thing printed, even in the newspapers.
The latest advanees in scientific knowledge,
the newest inventions and discoveries, in
every branch of human endeavor, are all
heralded in the morning or evening des-
patches. Years hence the text-books will,
as it were, embalm them in their solemn
pages. Why should the child be compelled
to sit in darkness with the light of knowl-
edge blazing all around him?

I, Some Survivals of Primitiwe Racial
Instincts in the American Negroes.—The
absence or, rather, scarcity of islands and
peninsulas and bays and seas along most
of the coast line of continental Africa has
exerted indirectly a profound influence on
African character. As a result, the Afri-
can tribes have been isolated from all the
great historical world movements, and have
remained stationary in their social and
tribal relations. Deprived of the stimulus
of commercial and maritime influences,
they have for centuries lain dormant in
respect to the higher or organic life of the
human species.
Herein les the secret of the southern
racial problem. The real crux of this diffi-
culty is not the mere color of the skin, as
is sometimes asserted. It is the sum total
of characteristics, mental and moral, of
which the exaggerated physique is the
material expression and vehicle—it is this
that constitutes a race problem when a
group of Afro-Americans comes into any

the influences of this unvarying African
environment and heredity all the influences
of American chattel slavery which served
to still further exaggerate tendencies al-
ready abnormally developed, and the re-
sultant is what is here designated negroism.
The significance of negroism lies in the de-
fective attempt, grotesque to the cultured
Anglo-Saxon mind, of the African mind to
incorporate into its own thought and being,
the real living thought and motives of the
Anglo-Saxon race. And herein too lies the
gist of the negro question.
The remedy for negroism is the develop-
ment of Americanism, that is, of intelligent
self-respect and a manly regard for others;
of self-reliance as manifested in industry
and economy and self-support; of a sim-
ple, pure, healthy, happy home life as op-
posed to polygamous indiscriminateness;
a regard for peace and good government
and good order rather than a scramble for
place and power and spoils; a love of ecun-
try, of home and a love of God manifested
in a life of simple sincere piety rather than
in manifestations of religious emotional-
ism unaccompanied or uninspired by the
spirit of a genuine Christianity.
On the Desirability of Founding an In-
stitute for the Study of Blood Poisoning.
P. A. Maianon, Philadelphia.
In these days of immense activity great
problems can be settled only by specializa-
tion. The prevention of disease is one of
these problems. Medical science deals
with the cure of disease; sanitary science
with its prevention.
Medical and surgical science has been
much endowed, but sanitary science has
somewhat lagged. Sanitary plumbing and
sanitary engineering are about all we hear
of in connection with sanitary science.
456
The writer has for the last thirty years
been associated with the sanitarians of
London, the hygienists of Paris and in a
general way with physicians taking partic-
ular interest in the prevention of disease,
and it has oceurred to him that a good pur-
pose would be served if an institute were
founded in this country for the special
study of blood poisoning, particularly as
regards the first step of infection. The
physiological, chemical and physical com-
position of normal blood is pretty well
known, but the immediate phenomena
which obtain before the appearance of
morbid symptoms do not seem to have been
studied to any very considerable degree.
The main object of such an institute for
the study of the different phases of blood
poisoning, their cycle and variety, should
be to find out and indicate the means to
prevent the infection in each ease.
Sociological Features of the National Irri-
gation Movement. Guy Euuiorr Mir-
CHELL, Secretary of the National Irri-
gation Association, Washington.
No question before the public to-day
presents more interesting sociological
phases than does the national irrigation
question in America, not only through the
great number of homes to be created by
artificially watering desert wastes but
through the far-reaching effect of the work-
ing out of a great government irrigation
policy and the general education of the
American people on the advantages of this
practise both west and east.
The social side of irrigation ean be de-
scribed in the single clause—irrigation sub-
divides and resubdivides lands into small
home tracts.
Irrigated communities average the small-
est farms in the world. The most highly
developed portion of the west contains
thousands of five and ten-acre farms from
which men are making comfortable livings.
SCIENCE.
[N.S. Vor. XXI. No. 534.
The social conditions of some of the most
intensely irrigated tracts are perhaps the
most nearly perfect of those of any com-
munities in the world.
Now the effect of the great government
irrigation work, which is being pushed
rapidly forward, will be to create a west-
ern empire of new homes and at the same
time, incidentally, thoroughly to educate
the people of the entire country on the sub-
ject of irrigation. The consequence will be
that irrigation practises will finally en-
thrall the eastern farmer. The facts as
they exist in European countries show that
irrigation can be practised with great profit
even on land which has sufficient rainfall
to grow paying crops. Irrigation is a crop
insurer, besides producing double yields,
and when it is applied to eastern farm
lands the same conditions will result which
are found in the arid region—the farms
will be divided into smaller and better
tilled tracts.
Along with the prosecution of the gov-
ernment irrigation policy and its great
agricultural educational features will come
the establishment. of rural colonies through-
out the entire country, home-acres for fac-
tory employees, making them to an ex-
tent independent of their daily wage, and
the gradual trend of the city congestion
back to the land as the primal source of all
wealth. Working along with this policy
of intensive farming and high cultivation
is a recognized movement to engraft a prac-
tical agricultural education, nature study
and handicraft work, upon our common
school system so that men and women of
coming generations will both want and
strive to own a home on a piece of land
and when they secure it will know how to
make it productive and attractive.
STATISTICAL SESSION.
Beef Prices. Frep C. Croxton, U. S.
Bureau of Labor.
€
Marcu 24, 1905.]
An advance in fresh beef affects the ex-
penditure of the working-man’s family as
much as would the same advance in the
price of each of the four items, flour, corn
meal, bread and milk. An advance in
beef of two cents per pound means (if he
buys the same grade and quantity), the ex-
penditure of an additional amount equal
to the cost of lighting, or to taxes and
property insurance combined, or to the
expenditure for books and newspapers.
The retail price of fresh beef at the
present time is about ten per cent. above
the average for the ten-year period from
1890 to 1899. The value per pound of
the fresh beef exported also shows a de-
cided advance. The average value for
the last five years was 11.4 per cent. above
the value for the preceding five years, and
13.3 per cent. above the value for the five
years ending June 30, 1894.
A study of prices during the last fifteen
years shows that with few exceptions the
prices of beef cattle, of fresh beef at whole-
sale and of fresh beef at retail advance and
decline together, but not to the same ex-
tent. The margin between beef at whole-
sale and at retail is usually rather close.
While some parts of each carcass are re-
tailed at two or three times the cost at
wholesale, a considerable portion, if sold
at all, must be sold for less than was paid
at wholesale. In the early part of the pres-
ent month, a ‘top’ carcass which cost the
retailer seven cents per pound was sold in
Washington as follows: 22 per cent. (in-
eluding trimmings) at three cents or less
per pound; 30 per cent. (including trim-
mings) at six cents or less per pound.
The demand for fresh beef at home has
increased, owing to the increase in popu-
lation, the greater proportion of persons
living in cities and towns, and to improved
industrial conditions during the past few
years. The demand abroad, as shown by
our exports for the five years ending June
SCIENCE.
457
30, 1904, was 21.7 per cent. greater than
for the preceding five years, and 55.6 per
cent. greater than for the five years end-
ing June 30, 1894.
The most difficult question encountered
in a study of beef prices is that of the
supply. The estimates of the Bureau of
Statistics of the Department of Agricul-
ture show an increase from 1890 to 1904
of 15.6 per cent. in the number of cattle
in the United States, while in the same
time population increased about 30 per
cent., and the exports of fresh beef in-
ereased 72.9 per cent. Deducting the
amount of fresh beef exported from the
amount sold by wholesale slaughtering and
packing establishments, the number of
pounds remaining per capita was 40.5 in
1890, 34.1 in 1900 and is estimated at 40
pounds in 1904. These figures do not of
course represent consumption, but afford
some measure of the relative amount of
fresh beef sold in each year.
One of the most important factors in de-
termining the beef supply is the corn crop.
The price of corn makes more abrupt
changes than does the price of cattle, yet
the course of the prices of the two com-
modities is almost identical.
Above are considered what may be called
the natural conditions in the beef industry.
It is possible that combinations of packers
exist, which would doubtless exert a
steadying influence on declining prices; or
a combination might be strong enough to
control to some extent the prices of cattle
bought for slaughtering, or the supply of
beef shipped, which would seriously affect
the price to the consumer.
Movement of Wood Prices and their In-
fluence on Forest Management. B. E.
Frernow, formerly U. 8S. Division of
Forestry.
Dr. Fernow refuted, by means of statis-
tices presented in the form of diagrams,
458
the position of one of the noted English
statisticians, Mulhall, that wood prices had
fallen and would continue to fall, because
the supply of timber was practically inex-
haustible. The data upon which the Eng-
lish authority based this conclusion were
shown to be worthless. The speaker
pointed out the difficulties of securing use-
ful data, from which to diagnose the past
and predict the future of price movements,
and explained that, and why, prices for
lumber did not really represent prices for
wood or stumpage. From careful compila-
tions of the experiences of European forest
administrations it was shown that wood
prices had for fifty to seventy years in-
creased at a compound rate of not less than
1.5 per cent. and for the last ten years at
a rate of over 2 per cent., being now at least
double what they were fifty years ago.
Such data as were available for the United
States showed the same tendency and
about the same rate; and as the knowledge
of the condition of timber supplies in the
world was growing, wood prices would in-
erease at an accelerated rate ‘until that
level has been reached which forces reduc-
tion of consumption.’ The influence of
the increase of wood prices on forest treat-
ment was discussed at length, as tending
to supplant the rough exploitation which
alone appeared profitable at present, by
forestry, 7. e., care for the reproduction of
a new wood crop.

The Wheat Situation in the United States.
Joun CasseL WriuuiAms, Washington
Correspondent, New York Journal of
Commerce.
SCIENCE.
[N.S. Vou. XXI. No. 534.
Since the season of 1901 there has been
a falling off in the production of wheat in
this country, while the increase in consump-
tion has gone steadily forward until the
point has been reached at which, tempo-
rarily, at least, domestic consumption is
about equal to the domestic supply and
only a small surplus is available for ex-
portation. The final figures of the De-
partment of Agriculture for the wheat crop
of 1904 issued by Chief Statistician Hyde
put the total yield at 552,399,516 bushels,
against 637,822,000 bushels in 1903, and
748,400,000 bushels in 1901. Though in
some years there have been considerable
quantities of wheat carried over from one
season to another in the visible supplies
and in the stocks estimated as remaining
in the hands of farmers, the exports of
wheat and wheat flour have, from year to
year, afforded an approximate measure of
the excess of production in the United
States over the domestic demand.
Owing to the falling off in production
and to the increase in domestic consump-
tion, exports of wheat from the United
States have temporarily, at least, prac-
tically ceased and exports of wheat flour
have been greatly reduced in volume.
The American miller, endeavoring to re-
tain his foreign market, is hampered, not
only by the shortage of the domestic supply
of wheat, but, also, by the inferior quality
of a large proportion of that grown dur-
ing the past season. The evidence sub-
mitted to the treasury department by
millers who have asked for an allowance
of drawback on the exportation of flour
made wholly or in part from imported
wheat shows that, while in former years
an average of four bushels and twenty
pounds of wheat have been required to
make a barrel of flour, the average quantity
of domestic wheat required this year is
four bushels and fifty pounds. Complaint
Marcu 24, 1905.}
is made that, even if domestic wheat is
used to make flour for export, it is ex-
tremely difficult to make the quality neces-
sary to keep up the reputation of the es-
tablished American brands. Across the
northern border in Canada there are ample
supplies of wheat of good quality, if the
Ameriean miller could draw upon that
supply of his raw material.
The great body of the millers would
welcome the absolute repeal of the duty
on foreign wheat and there would doubtless
be a vigorous demand for this repeal from
other elements in the population of the
United States if it were generally under-
stood that, for some months past, the price
of wheat in Canada has been from fifteen
to twenty cents per bushel lower than in
the United States, and that the effect of
this has been to increase the cost of flour
in the United States by from eighty-five
cents to one dollar per barrel, thus increas-
ing the cost of living to every customer of
wheat flour in the United States.
What is to be the future relation of the
domestic supply of wheat in the United
States to the domestic demand? The
operation of certain tendencies in Amer-
ican agriculture seem to indicate that
wheat production in the United States can
not be expected to increase in the future
at a much greater rate than will be neces-
sary to supply the increasing domestic de-
mand. It is not impossible that the ulti-
mate result of the operation of these tend-
encies will be to make the United States a
permanent importer of wheat under nor-
mal conditions.
SESSION ON PROBLEMS OF COMMERCE, ETC.
Present Status of Maritime Enterprise.

United States Merchant Marine Com-
mission, Boston, Mass.
While ocean shipping is in a distressed
condition in Europe, it is in a desperate

condition here. The Merchant Marine
Commission has visited within eight
months all of the chief ports of this coun-
try and it has not found anywhere so much
as one new steamship designed for foreign
trade in process of construction. It is,
therefore, more than temporary depression
which afflicts the ocean shipping of the
United States. We are face to face, unless
something heroic is speedily done, with the
final vanishing of an old, historic industry.
It will be generally agreed that President
Roosevelt sent his urgent appeal to Con-
gress none too soon. The report and
recommendations of the Merchant Marine
Commission will be laid before the Senate
and House next week.* Though they can
not be outlined beforehand, of one fact
every member of the Congressional Com-
mission is certain, and that is, that with-
out vigorous national aid and encourage-
ment of some kind we shall inevitably lose
the last of our deep sea mereantile marine,
not only the ships themselves, but the
skilled officers and seamen.
The Merchant Marine Commission in its
inquiry has found that all the maritime
nations of the world protect and encourage
their ocean shipping in some way or other.
The most conspicuous instance of this
practise is Great Britain’s recent grant of
$13,000,000 to build two new Cunard
steamships, which will receive besides an
annual subsidy of $1,100,000 for twenty
years. Within sixty years Great Britain
has expended about $300,000,000 in sub-
sidies to her steam lines through all
quarters of the world; and this, with the
vigorous discrimination of Lloyds against
foreign shipping, has made impregnable
the British mastery of the sea, which was
first gained by the navigation laws of
Cromwell and the victories of Nelson.

A160 SCIENCE.
The Merchant Marine Commission has
given some attention to the free ship
policy. In reply to inquiries addressed to
the chief American owners of foreign-built
steamships, these companies one and all
declare that they would not bring their
foreign ships under the American flag if
they were given an opportunity, unless Con-
gress by subsidy, bounty or discriminating
duty enabled them to meet the higher wages
of American officers and seamen. The
Merchant Marine Commission, therefore,
has been forced to turn to the alternative
of direct national aid and encouragement
to our merchant shipping. The exact con-
clusions which it has reached will be re-
vealed when the report and recommenda-
tions are presented to Congress.

Analogies Between the Evolution of Inter-
national and of Private Law. Epwarp
Linpsay, Warren, Pa., Academy of Sci-
ences.
As the ethics of a people are in advance
of its laws so are the ethics of the individ-
ual always in advance of the ethics of the
people as a whole. The individual is al-
ways in advance of the crowd, the group
or the state. We would, therefore, ex-
pect to find the laws governing nations in
their intercourse with each other in a less
developed state than those governing in-
‘dividuals in their relations with each other.
Such is in fact the case. A comparison of
[N.S. Vou. XXL. No. 534,
international law with the growth and
progress of private law will afford infor-
mation as to the stage and development
international law has reached and some-
thing of what we may expect from its
future growth. This comparison was made
between :
1. Treaties and Contracts.—Treaties are
contracts between nations. In_ inter-
national law in respect to treaties the bind-
ing force of the engagement is determined
more from the formalities of the declara-
tion of the treaty than from the agree-
ment itself. In an earlier stage of private
law this was also true of contracts; origin
and history of contracts.
2. War and Trial by Combat; War the
Recognized Means of Settling a Dispute.—
In private law at a certain stage was em-
ployed the judicial combat which degen--
erated into the duel and has now become
obsolete.
3. Arbitration and an Action at Law;
Arbitration a Rudimentary Judicial Proc-
ess.—In private law we have it to-day as a
survival in some instances and there is
much reason to think that it was a stage in
the evolution of law courts and legal pro-
ceedings which was passed through by
these institutions. International law may
be expected to follow the same course of
development in general as private law.
International legislation, however, prob-
ably is inadvisable. Growth of inter-
national law best assured by international
court to ascertain and declare the law in
concrete cases.
The Meaning of Maritime Expansion.
JOHN FRANKLIN CROWELL, Washington,
Dac:
The upshot of it all is that we as a people
are in the tropics. Moreover, we are there
in all probability to stay. Ten or fifteen
years ago a professor of history sneered at
the idea of the annexation of Cuba. But
Marcu 24, 1905.]
the recent reciprocity treaty put the com-
mercial relations between the two countries
on a basis which makes economic annexa-
tion inevitable. Furthermore, every lead-
ing British possession in the West Indies
has for some years been seeking reciprocal
trade treaties with the United States, as a
means of economic salvation. The fact is
that the American tropics find their nat-
ural market for raw materials in the
United States. We must find enlarged
markets in these as yet undeveloped
peoples. Step by step both the pressure
from within and the course of events from
without are drawing us out into relations
with transoceanie countries which already
make it necessary to look to the main-
tenance of communication with the differ-
ent continents by sea.
At last then we are numbered among the
great powers which have borne the burden
of the world’s colonization. We are there
primarily because of the inequality in the
degree of economic development, compar-
ing tropical communities with our own.
The relation of the more highly developed
countries of the temperate zone to the com-
paratively undeveloped peoples of the
tropies is one of the greatest of problems
arising out of maritime expansion. The
experience of most countries has resulted
in one form or another of political depend-
ence on the part of the natives; this polit-
ical dependence with its varied institutions
has its basis generally in an economic
dependence or rather interdependence.
Among these economic relations are in-
variably lines of communication and com-
merece by sea between the foreign country
and the dependent territories. Great
Britain requires control of the Mediter-
ranean by reason of her relations with
Egypt, India and Australia. One can not
understand the history of modern peoples
without taking into account this relation

With all of its dark pages, there are many
proofs of the truth that the greed for gain

manity, in dealing with these wards of the
northern races. The missionary spirit has
helped to temper the ferocity of mammon,
and sooner or later insisted on the abolition
of slavery throughout the entire region of
eonquest. There has been a moral ex-
pansion running parallel with the political
and the economic expansion. Develop-
ment of purchasing power rather than
wasteful exploration of the population has
come at last to govern tropical policy.

THE SAINT PETERSBURG CONFERENCE ON
THE EXPLORATION OF THE
ATMOSPHERE.
As some readers of ScrENCE may remem-
ber, the International Meteorological Con-
gress which met at Paris in 1896 appointed
a committee to further the exploration of
the free air, then already in progress in
Europe by means of balloons, and at Blue
Hill in this country with kites. The
committee bears the somewhat ambiguous
name: ‘International Committee for Scien-
tific Aeronautics,’ and has had for its presi-
dent Professor Hergesell, director of the
meteorological service of Alsace-Lorraine.
Originally consisting of eight members, it
now numbers about fifty, representing
eleven European countries and the United
States, for, although our national Weather
Bureau has not had a representative on the
committee, the writer attended the meet-
ings that were held at Strassburg in 1898,
at Paris in 1900 and at Berlin in 1902, and
has endeavored to advance the objects of
the committee in the United States.
The fourth meeting, appointed for last
autumn at St. Petersburg, was regarded as
of exceptional importance and, according-
462
ly, the invitations issued by the Imperial
Academy of Sciences brought together,
from ten countries, seventeen members of
the committee besides about sixty other
meteorologists and aeronauts, the latter
both civil and military. At the head of
the local committee of arrangements was
General Rykatchef, director of the Central
Physical Observatory, and to him the sue-
cess of the meeting is chiefly due, for, al-
though the war with Japan had reached an
acute stage, it was not allowed to alter the
scientific and social program. The first
session was held in the palace of the Acad-
emy of Sciences on August 29 (new style),
when the order of business was adopted,
and the same afternoon the conference was
formally opened by the Grand Duke Con-
stantine Constantinowitch, president of the
Academy, who brought the greetings of the
Czar: General Rykatchef then explained the
arrangements that had been made for the
meeting and Professor Hergesell reported
on the work that had been accomplished
since the committee had met two years
before.
The following day the scientifie meetings
were begun, these being open to members
of the conference, and, with the exception
of two days devoted to excursions, they
continued until September 3. There were
sessions both morning and afternoon which
were presided over successively by two
members of the committee, and the ques-
tions considered came under the following
heads: Organization of international ob-
servations, special investigations, instru-
ments and technical matters, resolutions.
As regards the first, it was deemed essential
that each country should possess a special
organization for the exploration of the at-
mosphere and that the results should be
published regularly. During the past
three years the cost of publishing such
observations in monthly volumes has

[N.S.. Vox. XXII. No. 534,
amounted to $10,000, and this has been
borne entirely by the meteorological sery-
ice of Alsace-Lorraine. It is now pro-
posed that the various countries participat-
ing in the exploration of the atmosphere
shall contribute $1,000 or $1,200 annually,
receiving in exchange copies of the publi-
cation, and this proposition is to be trans-
mitted through diplomatic channels to the
countries represented at the conference.
With respect to the international ascen-
sions of kites and balloons which, for sey-
eral years, have taken place on the first
Thursday of each month, it was decided to
continue this practise, but, in order to
study the successive diurnal changes, there
will be, in addition, ascensions on three con-
secutive days during April and August,
1905, the dates during the latter month
including the day of the total solar eclipse,
August 30, when an ascent of a manned
balloon was promised at Burgos, by the
Spanish representative, Colonel Vivez y
Vich. It was also decided that the balloons
should be despatched in each country at
the hour which corresponded to its daily
synoptic weather-map. A statement of the
number of ballons-sondes lost in Europe
showed that this did not exceed four per
cent. of those liberated. The committee
recommended that observations of cloud-
drift should be made at the time of each
balloon ascension, in order to determine the
motion of the upper currents, and in these
observations the nomenclature of the clouds
ought to correspond exactly with the inter-
national classification. For this purpose
a new edition of the ‘ International Cloud
Atlas,’ which is now out of print, will be
issued.
Dr. Assmann, director of the aeronautical
observatory of the Prussian Meteorological
Institute, described the new observatory to
be erected in large grounds, thirty-five miles
southeast of Berlin, because at the existing
Marcn 24, 1905.]
observatory, in the suburbs of that city,
the trailing kite-wires constitute a danger
to life and property. The new establish-
ment will be in every respéct a model one,
where balloon and kite ascensions are to be
made several times a day, a motor-boat on
a lake permitting the kites to be flown even
in calm weather, and, im this way, it is ex-
pected that practically continuous meteoro-
logical records will be obtained in the free
air. As an indication of what had already
been done in this respect, Dr. Assmann ex-
hibited a chart, encireling the hall, on which
were plotted the isotherms at different
heights above Berlin, obtained from the
ascensions of kites and captive balloons
made daily for more than a year. From
them Dr. Berson showed that the wind-
direction shifted to the right-hand with in-
creasing altitude. To complete an account
of the aeronautical establishments in Ger-
many for atmospheric soundings, Professor
K6ppen described the kite-station of the
Deutsche Seewarte, in Hamburg, where
kite-flights are made every day that the
wind conditions allow, the observations
being published the same day, with those
obtained simultaneously above Berlin, in
the weather-bulletin issued by the See-
warte. Professor Palazzo, director of the
Italian Meteorological Office, recounted
what was being done in Italy to explore the
free air, including the recent use of ballons-
sondes, and General Rykatchef explained
the development of the aeronautical section
of the Constantine Observatory at Paw-
lowsk, which was later visited by the mem-
bers of the conference. Here kite-flights
are made whenever possible, the observa-
tions being immediately published in the
Synoptic weather-report of the Central
Physical Observatory. The committee con-
sidered that a balloon and kite-station in
the southeast of Europe is desirable and ex-
pressed the hope that the Roumanian

463
Meteorological Service would cooperate in
the international ascensions, and also that
a kite-station might be established at Pola,
Austria, thereby filling a gan in the dis-
tribution of such stations.
Mr. Rotch stated that from the observa-
tions obtained with kites at Blue Hill dur-
ing eyclones and anti-cyclones the former
appeared to be the warmer up to a height
of at least two miles. Per contra, M.
Teisserene de Bort concluded from his ob-*
servations with ballons-sondes in France
that the vertical decrease of temperature
in cyclones up to six miles was faster than
it was in anti-cyclones. This last speaker
gave an account of flying kites from a
Danish gunboat in the Baltic in 1903, when
the record height for kites of more than
19,000 feet was reached, as mentioned in
Science, Vol. XVIII., pages 113-14, and
he also described recent experiments on his
own steam-yacht in the Mediterranean.
The most interesting communication, how-
ever, was by the president of the committee
and related to the atmospheric soundings
with kites that he had just executed on
board the steam-yacht of the Prince of
Monaco, while cruising in the Mediterran-
ean and in the vicinity of the Canary Is-
lands. It will be remembered that the
present writer proposed a more extensive
campaign of this nature at the Berlin
Aeronautical Congress, and unsuccessfully
apphed to the Carnegie Institution for a
grant of money to equip a steamship to
make a series of kite-soundings through
the trade-winds and doldrums.
in 1902 he endeavored to interest the
Prinee of Monaco in such a scheme, as
his colleague, Professor Hergesell,
ceeded in doing two years later, and the
results of these soundings, which Professor
Hergesell announced at St. Petersburg,
eminently justified the cooperation. The
northeast trade-wind was seen to diminish

nearly three miles, the southwest anti-
trade, which is supposed to form the re-
turn-current, was not encountered, though
it has been reported at a much lower alti-
tude upon the Peak of Teneriffe. The
temperature was found to decrease up to
ea third of a mile in height, where there was
an inversion of temperature persisting
throughout a thick stratum and then a
rapid decrease with increasing height, these
changes being analogous to those pre-
vailing within areas of high barometric
pressure over the land. The interesting
investigations of Professor Hergesell fur-
nish additional evidence of the importance
and feasibility of carrying out soundings
of the atmosphere across the equator and
into the southeast trade-winds. The em-
ployment of kites to obtain meteorological
observations on steamers pursuing vheir
regular courses, the practicability of which
the writer demonstrated on a voyage across
the Atlantic in 1901 (see Science, Vol.
XIV., pages 896-7), was discussed and it
was reported that two German steamship
lines and a Spanish company had agreed
provisionaliy to allow observations with
kites to be made on their steamers. In view
of the importance of studying the meteoro-
logical conditions high above the oceans,
the committee requested the meteorological
bureaus of the various countries to propose
to their maritime agencies that kites be
employed on the mail and other subsidized
vessels, the results of these negotiations to
be reported at the next conference.
Recording instruments for balloons and
kites were discussed in detail, but it was
considered inexpedient, at the present time,
to recommend the adoption of any special
type of instrument, though the committee

requested that a description of the instru-
ment employed should accompany all pub-
lished observations. The errors of aneroid
barometers, caused by residual elasticity
and by temperature, were said to be less
with the Bourdon tubes than with the
usual cylindrical vacuum-boxes and, con-
sequently, the former are to be preferred
for ballons-sondes. Very light instru-
ments of French and German construction
were exhibited, in which the barometer was
a Bourdon tube and the thermometer either
a bimetallic bar, bent in cireular form,
or a German-silver tube ineclosed in a
polished one. Professor Hergesell showed
his instrument for manned balloons, where
the necessary ventilation of the thermom-
eters is supplied by an exhaust fan, placed
in the thermometer-tube just mentioned,
and driven by a storage-battery and Dr.
Shaw, secretary of the London Meteorolog-
ical Office, presented Mr. Dines’s simple
meteorograph for kites that costs but
twelve dollars. An apparatus was shown
by the writer for determining on a moving
steamer the velocities of the true and ap-
parent wind—which latter only is utilized
in kite-flymg—the speed and course of the
vessel enabling the triangle of forces to
be solved. Most of the other apparatus
which was brought before the conference
related to the balloons or their accessories.
The closing session of the conference was a
ceremonious one at which Count de La
Vaulx, of Paris, and Dr. Berson, of Berlin,
gave accounts of the longest balloon voy-
age, from Paris to Kief, and the highest
ascension, to 35,000 feet, executed by them
respectively.
As is usual at these international gath-
erings, the social entertainments and visits
to scientific establishments were the most
interesting features. The first of these
was an informal reception at the Grand
Hotei before the conference opened, fol- —

lowed the next evening by a sumptuous
banquet at the Army and Navy Club, which
was attended by the Grand Dukes Con-
stantine and Peter, as well as by many
Russian officers and scientific men of high
rank. The Imperial Geographical and
Technical Societies held a joint session in
honor of their foreign guests, which was
followed by a supper. After a morning
spent at the Pawlowsk Meteorological Ob-
servatory, when a ballon-sonde and kites
were sent up from the aeronautical
grounds, the Military Aeronautical Park
was visited in the afternoon and here all
the apparatus of the balloon corps could be
inspected, including that which its com-
mander, Colonel Kowandko, was about to
take to the seat of war in Manchuria. An-
other day was oceupied by an excursion
into the Gulf of Finland on a small govern-
ment cruiser. Notwithstanding a gentle
wind, the light hemispherical kites of Mr.
Kusnetzof were easily raised by the motion
of the vessel and proved very stable. THE MACMILLAN COMPANY “nT sve

Volume 1. Cloth, 8vo. $3.00 net (postage 18c.).
The field covered by the present volume is that of direct-current electro-magnetic machinery
and apparatus, and the book is almost exclusively confined to dynamo-electric machinery. The
text refers in numerous places to various books and publications so as to make the book serviceable
in connection with any first-class college course. This also adds to its value as a reference book.
Volume II., in preparation, will deal with alternating-current machinery, etc.
- “Tt is a book which can be thoroughly recommended to all students of electrical engineering who
are interested in the design, manufacture, or use of dynamos and motors .
. . A distinct
and valuable feature of the book is the list of references at the beginning of each test to
the principal text-books and papers dealing with the subject of the test.

CRITICAL COMMENT.
‘« We feel that by this time praise of the work is unnecessary. When the first volume appeared we
praised it without stint, expressing the hope at the same time that the other volumes would be up to
the standard of the first. This hope has been realized, for the work has shown the rare merit of evenness
throughout. Asvolume after volume has appeared, the medical world has become more and more apy
preciative of it until now all that we can say is of little account, for each reader has his own opinion of the
work ; at least it would seem so from our observation. The opinion oftenest expressed is in accord with our
own, namely, that the work is by all odds the best presentation of the science and the art of medicine
in the English language.”—New York Medical Journal.
‘« The increasing frequency with which this system of medicine is referred to in general medical
literature indicates the popularity of the work and the authoritative nature of the contributions... . A
work like this is almost a necessity to athoroughly well-read physician. —Pennsylvania Medical Journal.

JOURNAL OF PEDAGOGY
ESTABLISHED IN 1887
An Educational Magazine of interest to all serious students of education.
Some of the ablest contributions now being made to educational
literature are appearing in the JournaL or Pepacocy.
A REPRESENTATIVE OPINION
“Tn building up the occupation ot teaching till it becomes a true profession,
no magazine is rendering more significant and vital service than the JOURNAL
OF PEDAGOGY, which admirably displays the interest of the editor in the science
and art of education. Its articles have always been noteworthy for their
strength and freshness; its book reviews have been conspicuously valuable,
exceeding in number those of the several other leading magazines combined.
No field of edu ‘ational effort has been neglected ; and there has been a reason-
able apportionment of space alike to the university, the high school, the
elementary school, and the kindergarten. Those who are earnest for the better-
ment of American education view with the greatest seriousness the endeavor
of such a magazine as the JOURNAL OF PEDAGOGY to represent the best thought
and practice of the times, and by representing that thought and practice to
encourage their influence. To publish such a periodical is a noble enterprise
for the welfare of American schools and of the American nation.’’—Dr. W. E.

THE SIXTH ANNUAL MEETING OF THE S8O-
CIETY OF AMERICAN BACTERIOLOGISTS.
THE sixth annual meeting of the Society
of American Bacteriologists was held at
the Laboratory of Hygiene, University of
Pennsylvania, Philadelphia, Pa., on De-
cember 27 and 28, 1904.
The opening address was by President
F. G. Novy, of the University of Michigan,
on ‘The Hematozoa of Birds.’
On the Hematozoa of Birds: F. G. Novy,
University of Michigan.
An abstract or partial summary of the
results obtained in this study appeared in
American Medicine, November 26, 1904.
The work in full will come out in two
papers, the first of which, dealing with the
Trypanosomes in birds, will appear in the
second number (1905) of the Journal of
Infectious Diseases; the second paper, deal-
ing with the Cytozoa, may be expected in
the third number of that journal.
The Effect of Freezing on Bacteria: ERWIN
F. SmirH and DEANE B. SwIncte, U. 8S.
Department of Agriculture.
More than 100 freezings were made
using about a dozen different bacteria—
saprophytes and plant and animal patho-
genic forms. Quantitative determinations
were made in all cases. With the excep-
tion of Bacillus radicicola, all of the ex-
posures were made in +15 peptonized
beef bouillon, using cultures 24 to 48 hours
old. Part of the freezings were made in
liquid air, the time of exposure varying
from 10 minutes to 24 hours, but usually
one half hour. The rest were made in salt
482
and pounded ice, the time of exposure be-
ing 2 hours. The freezings were made in
5 ee. portions of bouillon in test-tubes of
resistant glass. The thawings were made
in tap water at 16° to 18° C. The inocu-
lations for each set of plates were made in
the same way, 2. e., usually with the thin-
nest meniscus it was possible to obtain
across a l-mm. platinum oese. The petri
dishes were carefully selected, those taken
being approximately 9 em. in diameter, with
flat bottoms. The regular method of work
was to make three poured plates (checks)
from the inoculated tubes after insuring
thorough diffusion, which was obtained by
stirring with the platinum rod, shaking
and allowing to stand one half hour. The
tube was then immediately lowered into
the liquid air and frozen slowly from the
bottom up to avoid eracking. (This us-
ually required four minutes.) As soon as
the one half hour or other predetermined
time of exposure had elapsed, the tube was
removed, warmed for about 3 minutes in
the laboratory air and then thawed in
water (which usually required another 5
minutes). As soon as the thawing was
completed, three more poured plates were
made, and these together with the three
check plates were then incubated in the
dark at 30° C., until the colonies were in
good condition for counting—a _ period
varying, according to the species, from one
to several days. The plates were all put
on a leveling apparatus as soon as poured,
and in general the distribution of the
colonies in the nutrient agar was very uni-
form. When the plates were sown thin
enough, the entire surface was counted (60
sq. em.); for the thicker sowings the aver-
age of 10 or 12 sq. em. was used, or of one
half the plate. The following samples
from two of the thirty or more slides ex-
hibited will give a general idea of the
method and results:

gardens to consult when planning one, perhaps no volume in this Elizabethan era
of treatises on floriculture is better than ‘‘ The Garden ofa Commuter’s Wife.”’
Mrs. Alfred Ely’s Another Hardy Garden Book
gives simply the results of years of her own experiences in raising vegetables, flowers,
fruits, transplanting trees, etc. The New York Zribune describes Mrs. Ely as ‘‘ the
wisest and most winning teacher of the fascinating art of gardening that we have met
in modern print.’’ With 49 full-page plates. $1.75 net (postage 12c.)

It was of this book that Mrs. ALICE MORSE EARLE wrote: ‘‘ Let us sigh with
gratitude and read the volume with delight. For here it all is—what we should plant
and when we should plant it; how to care for it after itis planted and growing;
what to do if it does not grow and blossom; what will blossom, and when it will
blossom, and what the blossom will be.’ (From an extended review in The Dial.)

‘. 0seseiente ae 50,000
St. John’s Collesew ia. soeeirras ae 16,700
During the past week a gift of $100,000 to
Rochester University for the construction of
a scientific building and $50,000 to Norwich
University, Vermont, half for a library and
half for an engineering department, have been
announced.
Ir is announced that a gift of $250,000 has
been made to Northwestern University by
Milton H. Wilson, a resident of Evanston, and
one of the trustees of the institution.
Tue London Times states that further
papers have been published by the government
of India in respect to the late Mr. Jamsetjee
N. Tata’s offer of an endowment in the shape
of properties valued at £200,000 for the crea-
tion of an Institute of Indian Research at
Bangalore. Certain conditions in respect to
government assistance were attached to the
offer, which was first made six years ago, and
these have been the subject of prolonged dis-
cussion and correspondence between the goy-
ernment, Mr. Tata during his lifetime, and his
representatives. The papers now published
show that the difficulties in the way of a set-
tlement have been removed. Guarantees have
been offered by the representatives of the donor
to secure the full income estimated from the
endowment properties, and the management of
the latter is vested in a board whose chairman
is to be an officer selected by the Bombay gov-
struction of the necessary buildings and pro-
vision of scientific apparatus, the government
wiil make an annual grant to the institute of
half the local assets up to a limit of 14 lakhs
of rupees, provided that the institute is con-
ducted on lines approved generally by the goy-
ernment. “
Tue Barney Memorial Science Hall of
Denison University was completely destroyed
by fire at two o’clock a.m., March 30. The
building was erected in 1894 at a cost of
$45,000, and the value of the equipment within
it was also about $45,000. The department of
chemistry, in which the fire started, suffered
total loss. The department of physics, which
had installed several thousand dollars worth of
new apparatus this season, lost most of its
equipment, including the greater part of the
manuscripts and instruments of the researches
of Professor C. W. Chamberlain. The equip-
ment of the department of geology, including
about $7,000 worth added this year, was nearly
all saved. The departments of zoology and
botany saved about half of their equipment.
There is about $40,000 insurance on the build-
ing and contents, and the hall will be rebuilt
at once. The most serious loss is the scien-
tifie library which has been accumulated dur-
ing the past twenty years, chiefly through ex-
change with Denison publications and which
was one of the richest collections of society
transactions and similar serials in the middle
west. In making good, so far as possible, this
severe loss the generous cooperation of au-
thors and learned societies is requested. Au-
thors’ separates, duplicates, or society publica-
tions, if sent to the permanent secretary of the
Denison Scientific Association, Granville,
Ohio, will be gratefully accepted as a nucleus
of a new library. :
Rev. Freperick W. Hamitton, D.D., pastor
of the First Universalist Church of Roxbury,
has been elected temporary president of Tufts
College, to fill the vacancy caused by the death
of President Capen.
Mr. R. P. Grecory, M.A., of St. John’s Col-
lege, has been appointed senior demonstrator
in botany at Cambridge.

PENETRATING RADIATION
WITH THE
ASSOCIATED
A-RAYS.
As the following investigation is made
with the aid of nuclei, certain of their
properties bearing on the present subject
will first have to be specified. Exhaustions
are preferably made at a pressure differ-
ence (8p) just below the point (to be called
fog limit) at which dust-free non-energized
saturated air condenses without foreign
nuclei. 6p depends on the particular ap-
paratus used.
1. Fleeting Nuclei.—Let the X-radiation
to which the dust-free air is exposed be
relatively weak, so that the density of ion-
ization may remain below a certain critical
value. The nuclei observed on condensa-
tion are then very small and they require a
high order of exhaustion, approaching the
fog-limit of non-energized air. They are
usually instantaneously generated (within
a second) by the radiation, so that their
number is definite independent of the time
of exposure. They decay in a few seconds
after the radiation ceases; 7. e., roughly to
one half their number in two seconds, to
one fifth in twenty seconds in the usual
exponential way. I fancy that these nuclei
are what most physicists would call ions;
but nevertheless the particles are not of a
562
size, their. dimensions depending on the in-
tensity of the penetrating radiation to
which they are usually due; and they pass
continuously into the persistent nuclei as
shown in the next paragraph, where decay
of ionization and of nucleation are very
-different things. Finally (§3) they are
stable on solution. The case seems rather
to be one in which the rate of decay exceeds
the rate of production. The following is
an example of data bearing on this case,
N being the number of nuclei caught per.
cubie centimeter. The anticathode is at a
distance from the fog-chamber and the ex-
haustion carried to the verge of the fog-
limit of dust-free air.

The two series refer respectively to genera-
tion and to decay.t
2. Persistent Nucler.—If the X-ray bulb
is approached nearer the fog-chamber or if
a more efficient bulb is used so that the
density of the ionization within the fog-
chamber is sufficiently increased, the rate
of production of nuclei will eventually ex-
ceed the rate of decay. The nuclei are now
persistent for hours after the radiation
ceases. The number N per cubic centi-
meter increases in marked degree and at
an accelerated rate with the time of ex-
posure to the radiation, certainly for ten
minutes or more, barring the invariable loss
of efficiency of the X-ray bulb. These
nuclei are large, requiring very little super-
saturation for condensation and are much
like any ordinary nuclei. They are pro-
nouncedly of all sizes and the initial co-
ronas are apt to be distorted and stratified
beyond recognition. Whirling rains and
accompany the first condensation.

chamber, the end near the bulb is at first
the seat of growth which gradually extends
to the other end, as I have shown else-
where.* The following two series of data
showing the generation and decay of nuclei
in question may be cited as illustrations.

Hence there is a decay of one half inten
minutes, and to one fifth in eighty minutes,
or the degree of persistence is 200-300
times larger than in the first paragraph.
The data indicate, moreover, that both of
these extreme types of nuclei and all inter-
be tested by changing the pressure differ- —
ence, 6p, on exhaustion. Intermediate :
rates of generation and decay may be ob- |
tained by moving the bulb nearer to or
farther from the end of the fog chamber.
Finally the rates at which the nuclei and
the ionization severally decay, between ;
which it would be difficult to distinguish
in the case of the very fleeting nuclei, stand
in sharp contrast with the persistence of —
the nuclei of the present paragraph.
3. Fleeting Nuclei Become Persistent on —
Solution. Origin of Rain.—ULet the fog- ©
chamber be exposed to radiation for a few
seconds and thereafter exhausted (8p—25)
as usual. Closing the exhaustion cock and
allowing only time enough to measure the
first corona, let the influx cock be opened
and the fog-chamber be refilled with dust-
free air. The (primary) corona observed
is thus dispelled before much subsidence of —
fog-particles can take place, though the .
rain will naturally drop out. If the fog-
chamber is now left without interference

(the radiation having been cut off imme-
diately after the first exhaustion) for one
or more minutes or longer, a second ex-
haustion to the stated limits will show a
large (secondary) corona relatively to the
primary corona. In other words, relatively
many of the fleeting nuclei or ions caught
in the first fog have persisted, whereas
without condensation, they would have van-
ished at once after the radiation was cut
off. The following is an example of data
bearing on this point, ¢ denoting the time
elapsed from the evaporation of the first
corona to the precipitation of the second,

The experiments are complicated by the
variable X-ray bulb; but it is obvious that
while all the nuclei would have vanished
in a few seconds without condensation,
about one fourth (in other experiments
more) persist indefinitely if reevaporated
after condensation from fog-particles.
This result has an important bearing on
the whole phenomenon of condensation and
nuclei. Clearly the latter, after the evap-
oration specified, become solutional or water.
nuclei, in which the original fleeting nu-
cleus or ion behaves as a solute. The de-
ereased vapor pressure due to solution
eventually compensates the increased vapor
pressure due to curvature, after. which at a
definite radius, evaporation ceases and a
water nucleus results. Such a nucleus,
however small, must be large in comparison
with the dissolved ion. Hence on conden-
sation the water nuclei will capture the
moisture soonest and grow largest. Now
in any exhaustion about one eighth of the
fog particles, 7. ¢., those which are smallest
and whose nuclei have been caught at the
end of the exhaustion, regularly evaporate

water, nuclei. These are then the first to
be caught in a sueceeding exhaustion. This
is the explanation of the rain which not
only accompanies all coronas in dust-free
air, but is often dense. It is also an ex-
planation of those indefinite alternations
of large and small coronas (periodicity)
which I described in detail elsewhere.
4. Secondary Generation.—This is a
curious phenomenon, showing that the de-
caying nucleus is apparently radioactive,
or that the walls of the fog-chamber are so,
or. else that the large nuclei if left without
interference break into a number (on the
average about three) of smaller nuclei,
whereby the nucleation is actually in-
creased in the lapse of time after exposure.
In other words, if the nucleation is ob-
served without cutting off the radiation
in one case, and if in the second ease the
nucleation identically produced is observed
at a stated time after the radiation has
ceased, the number in the latter case
(anomalously enough) is in excess. The
following examples make this clear, the X-
ray bulb being 5 em. from the fog-chamber,
and the exhaustion carried to 8p = 20 em.

Polynoide and Nereide, and drafting de-
scriptions of species belonging to other
families. The determination of the rela-
tions of the various sexual phases of the
species of the latter family being a matter
of considerable difficulty, the collection of
suitable material for this purpose consumed
much time. The life history of Platynereis
megalops proved to be quite as complex as
that of the classical P. Dumerilii, present-
ing, however, some important differences.
With the exception of Nereis arenaceoden-
tata, heteronereids of all the species have
been found. An additional new species of
Nereis was also discovered. The Polynoide
and other scaly polycheta are of well-
known species, though several new to the
region have been found. The large felted
polychxte, commonly called the ‘sea mouse,’
of American waters, has always been iden-
tified with the European Aphrodite acu-
leata. A careful study of specimens taken
off Nantucket and Marthas Vineyard show
that the species occurring there is quite
distinct. The dredging operations con-
nected with the biological survey resulted
in large collections of polychexta, the de-
termination and recording of which re-
quired much time. Besides adding several
forms to the known fauna of the region,
the most interesting of which is the remark-
able Spiochetopterus oculatus, this work
has added greatly to our, knowledge of the
loeal distribution of certain species.

George H. Parker, Ph.D., assistant pro-
fessor of zoology, Harvard University, con-
tinued, as salaried investigator, his experi-
ments of a previous summer upon the hear-
ing of fishes, devoting especial attention to
the functions of the ear of the squeteague
(Cynoscion regalis). The latter consists of
a dorsal utriculus, with three semi-circular
canals, and of ventral sacculus containing
a large otolith. The cavity of the utriculus
does not communicate with that of the sac-
eulus; hence the ear of this fish, unlike that
of most vertebrates, is represented anatom-
ically by two separate parts. When the
utriculi and their appended semi-circular
canals and nerves were cut, the fishes
showed characteristic disturbances in their
equilibrium, and these disturbances per-
sisted till death. Such fishes were as re-
sponsive as normal ones to sound vibrations
produced by tapping with a mallet on the
side of the wooden aquarium in which they
were kept. When the otoliths, which are
normally quite freely movable in the sac-
euli, were pressed by means of pins against
the outer, non-nervous sides of their cham-
bers and were thus fastened, the fishes
showed no disturbance of equilibrium, but
did not react to sound vibrations as do
normal fishes. It, therefore seems prob-
able to Dr. Parker that the utriculus and
the semicircular canals are sense organs
concerned with equilibrium, and that the
sacculus with its contained otolith is an
organ of hearing.
Henry F. Perkins, instructor in zoology,
University of Vermont, and Carnegie re-
search assistant, continued his endeavors
to rear the eggs of Gonionemus murbachii,
with view to a study of the embryology of
this form. This task has proved extremely
difficult in the past, but preliminary steps
were successfully taken. Towing collec-
tions of various hydromeduse were also
made from the wharf, furnishing material

were taken from 57 dog-fish and 26 men-
haden, and those organisms which appeared
to be of constant occurrence were isolated
in pure culture. So far as his work has
been carried, Mr. Raiford believes that all
of the bacteria found are commonly known
species.
H. W. Rand, Ph.D., instructor in zool-
ogy, Harvard University, collected and
prepared material for studies of the venous
system of the skate. Injections were made
of the hepatic portal, cardinal and lateral
veins, with a view to determining the rela-
tions and connections of these several sys-
tems of veins in the posterior region of the
abdominal cavity. Dr. Rand also made a
series of observations on the respiratory
movements of the skate, with special refer-
ence to the functions of the spiracle.

occupied with (1) work upon the biolog-
ical survey of the marine fauna and flora
of the vicinity of Woods Hole (see above),
(2) the card catalogue record of local spe-
cies (see above), (3) experimental and
statistical studies of various fishes with
reference to adaption and selection. In
the experimental part of this work, Dr.
Sumner was assisted by Mr. D. W. Davis,
in the biometric part by Messrs. Davis,
Metcalf, Morse and some other assistants.
E. E. Watson, student in Iowa Univer-
sity, was engaged in biometric studies of
various local erabs.
Chas. B. Wilson, A.M., professor of biol-
ogy, State Normal School, Westfield, Mass.,
carried on studies of parasitic copepods,
both living and preserved material being
used. Many interesting facts relating to
the ecology of these parasites, some of pos-
sible economic value, were discovered. In
a number of cases the life history was
traced partially or completely. A consid-
erable number of new species were found.

ALBATROSS EXPEDITION TO THE BASTERN
PACIFIC.*
ii:
WE left Callao for Easter Island Satur-
day afternoon, December 3; as far as 90°
west longitude we remained in the Hum-
boldt current, as we could readily see from
the character of the temperature serials
and from the amount of pelagic life we
obtained from both the surface and the
intermediate hauls. This current also af-
fected the bottom fauna, which was fairly
rich even as far as 800 miles from the shore
while we remained within the limits of the
northern current. As soon as we ran out-
side of this the character of the surface
fauna changed; it became less and less
abundant as we made our way to Easter
Island, the western half of the line from
Callao becoming gradually barren. This
current also affected the deep-sea fauna to
such an extent that towards Easter Island,
at a distance of 1,200 to 1,400 miles from
the South American continent, our trawl
hauls were absolutely barren; the bottom
for the greater part of the line was covered
with manganese nodules on which were
found attached a few insignificant siliceous
sponges, an occasional ophiuran, and a few
brachiopods or diminutive worm tubes, the
same bottom continuing to Sala y Gomez
and between there and Easter Island. Sala
y Gomez and Easter Island are connected
by a ridge, on which we found 1,142 fath-
oms near Sala y Gomez, and 1,696 fathoms
between that point and Easter Island. The
ridge rises rapidly from about 2,000 fath-
oms, the general oceanic depth within about

100 miles, to over 1,100 fathoms within a
comparatively short distance from both
Sala y Gomez and Easter Island.
The southern part of our line from
Easter Island to the Galapagos shows all
the features characteristic of the western
part of the line from Callao to Easter
Island ; like the latter, as far as the twelfth
degree of southern latitude, it proved com-
paratively barren, the bottom consisting of
manganese nodules to within about 250
miles of the Galapagos. The pelagic and
intermediate fauna from Easter Island to
12° south latitude was very poor, and the
serial temperatures show that we were out-
side and to the westward of the great Hum-
boldt current. But near the twelfth degree
of southern latitude a sudden change took
place; the pelagic and intermediate fauna
became quite abundant again, and soon
fully as rich as at any time in the Hum-
boldt current. There was also a marked
change in the temperature of the water as
indicated by the serials, showing that from
the twelfth degree of southern latitude to
the Galapagos we were cutting across the
western part of the Humboldt current.
The great changes of temperature which
took place in the layers of the.water be-
tween 50 and 300 fathoms are most strik-
ing, and show what a disturbing element
the great mass of cold water flowing north
must be in the equatorial regions of the
Panamie district to the south and to the
north of the Galapagos. South of the
Galapagos the western flow of the Hum-
boldt current must be nearly 900 miles
wide, and of about the same width when
running parallel to the South American
coast. :
The range of temperatures between 30
fathoms and 150 fathoms is at some points
as great as 21°. Such extremes can not
fail to affect the distribution of the pelagic
fauna, and may account for the mass of
dead material often collected in the inter-
SCIENCE.
573
mediate tows at depths of less than 300
fathoms, when the range becomes as great
as 28°. Such a range of temperature is
far greater than that of the isocrymic lines
which separate coast faunal divisions. The
bottom fauna, as we entered the Humboldt
eurrent going north, gradually became
richer in spite of its being covered with
manganese nodules. ;
The two lines centering at Easter Island
developed the Albatross Plateau indicated
on the Challenger bathymetrical charts, on
the strength of a few soundings reaching
from Callao in a northwesterly direction
and of a couple of soundings on the twen-
tieth degree of latitude. The Albatross
Plateau is marked as a broad ridge sep-
arating the Buchan Basin from the deep
basin to the westward, of which Grey Deep
and Moser Basin are the most noted areas.
Our line from Easter Island to the Gala-
pagos showed a wonderfully level ridge,
varying in depth only from 2,020 to 2,265
fathoms in a distance of nearly 2,000 miles.
The soundings we made to the eastward
from the Galapagos to the South American
coast, and to the westward of Callao, as
well as on the line from Callao to Easter
Island, all indicate a gradual deepening to
the eastward to form what the Challenger
has called the Buchan Basin, with greatest
depths of 2,400 to over 2,700 fathoms,
and passing at several points near the coast
to Milne-Edwards Deep, Haeckel Deep,
Kriimmel Deep and Richards Deep, some
of them with a depth of over 4,000 fathoms.
According to the Challenger soundings the
Juan Fernandez Plateau connects with the
Albatross Plateau and forms the southern
limit separating Buchan Basin from the
Barker Basin to the south of the Juan
Fernandez Plateau.
At Easter Island we found our collier
awaiting our arrival. We moved from
Cook Bay to La Pérouse Bay to coal, as
there was less swell there than in Cook Bay,
574
where we could scarcely have gone along-
side for this purpose.
Considerable shore collecting was done
at Easter Island. We must have brought
together at least thirty species of plants.
The flora of Easter Island is very poor.
There are no trees nor, native bushes—not
even the bushes which characterize the
shore tracts of the most isolated coral reefs
of the Pacific are found there; and yet
some of the equatorial counter-currents
must occasionally bring some flotsam to its
shores. We collected a number of shore
fishes and made a small collection of the
littoral fauna. The fishes have a decided
Pacific look, and the few species of sea-
urchins we came across are species having
a wide distribution in the Pacific.
While coaling, we spent some time ex-
amining the prehistoric monuments which
line the shores of Easter Island. During
our stay at La Pérouse Bay we visited the
platforms studding the coast of the bay,
and made an excursion to the crater of
Rana Roraka, where are situated the great
quarries from which were cut the colossal
images now scattered all over the island,
many of which have fallen near the plat-
forms upon which they were erected. Near
Rana Roraka, at Tongariki, is the largest
platform on the island, about 450 feet in
length, to the rear of which are fifteen huge
images which have fallen from the pedes-
tals upon which they once stood. The
plain in the rear of the platform is crowded
with stone houses, most of which are in
ruins.
On our return to our anchorage at Cook
Bay, we examined the platforms within
easy reach of the settlement, and also the
crater of Rana Kao, on the north rim of
which, at Orongo, are a number of the
stone houses built by the people who quar-
ried the great stone images. At Orongo
are also found sculptured rocks, but neither
the sculptures nor the images show any

artistic qualities, though the fitting of some
of the cyclopean stones used in building
the faces of the platforms indicate excel-
lent and careful workmanship. To Mr. C.
Cooper, manager of the Easter Island Com-
pany, we are indebted for assistance while
visiting the points of interest of the island.
He was indefatigable in his exertions in
our behalf.
We took a number of photographs dur-
ing our stay; illustrating not only the pre-
historic remains, but giving also an idea of
the desolate aspect of Easter Island during
the dry season.
We arrived at Wreck Bay, Chatham
Island, Galapagos, on the third of January,
where we found a schooner with a supply
of coal. As soon as the ship has been over-
hauled and coaled we shall start for Manga
Reva, where we ought to arrive the last
days of January. We reached Chatham
Island towards the end of the dry season.
Everything is dried up, the vegetation
seems dead with the exception of a few
small wild cotton plants, weeds, cactus and
an occasional mimosa; and the great barren
slopes present fully as uninviting an aspect
as when Darwin described them. When
the Albatross visited the Galapagos in
March, 1891, everything was green, pre-
senting a very marked contrast to its pres-
ent desolate appearance.

ical study of current research in this field,
Miss Clerke presents in her latest work a lucid
account of pending problems in astrophysics.
Aprit 14, 1905.]
Her brilliant style of writing is maintained
throughout, and is sure to fascinate even the
reader who does not fully comprehend her
meaning. Sometimes, indeed, her lavish use
of synonyms must puzzle those not familiar
with the subject; but it carries her and her
readers lightly and pleasantly over some chap-
ters that would certainly be dry in the hands
of most authors.
The keynote of the book is suggestiveness,
as the author points out in the preface, and
there could be no better tribute to her success
in this respect than the use made of her work
by astronomers. She clearly differentiates the
known and the unknown, and emphasizes what
ought to be found out.
The book can be commended to the atten-
tion of the physicist and the chemist. It is
unfortunate that so few workers in the field
of chemistry seem to take a positive and active
interest in the problems of astrophysics; for
in many respects its progress is being delayed
while developments are awaited from the
chemical laboratories. When these develop-
ments come, as when Ramsay solved the mys-
tery of helium, the forward movement is
rapid. Students of electricity also ought to
find considerable of interest in this book and
its topics, for our nearest approaches to labo-
ratory representations of stellar phenomena
seem to be of an electrical character. Yet
we really do not know at all how these elec-
trical phenomena can be brought into their
proper relation to the thermal conditions
which doubtless obtain in the stars.
The work before us is divided into two
parts, ‘ Problems in Solar Physics’ and ‘ Prob-
lems in Sidereal Physics,’ the second part oc-
cupying something more than two thirds of
the volume. The fourteen chapters of the
first part deal with the sun’s chemistry, and
separately with its successive envelopes. Two
chapters are devoted to sun-spots, and they
sufficiently disclose our ignorance as to the
nature and cause of these familiar but no less
puzzling phenomena. The last three chap-
ters treat of the solar rotation, the solar cycle
and ‘the sun as a whole.” The author’s point
of view is the safe and conservative one which
has been taught by Young and by Huggins.
SCIENCE.
518
Schmidt’s refraction theory of solar phenom-
ena is regarded as largely of academic interest.
The general reader may safely accept the au-
thor’s comments as well balanced; and there
is no concealment, but rather a frank avowal,
of the extent of our present ignorance on the
problems of the sun.
Part II. includes forty-one chapters and
enters into the personal details—the vie
intime—of the stars, possibly rather too
minutely for the general reader. But it is
decidedly interesting reading, and the reviewer
must confess that the belatedness of this re-
view is due to the tendency to peruse these
details repeatedly to the detriment of obtain-
ing a broad survey of the book. The author
adopts a rather simple scheme for classifying
stellar spectra and gives to each class a chap-
ter. Anomalous and bright-line spectra re-
ceive an Spectroscopic
binaries and eclipsing stars also get consider-
able attention. ‘The problem of Beta Lyre’
occupies a chapter of twenty pages, while the
longest chapter is devoted to temporary stars,
including Nova Persei. After clusters have
been discussed, the nebule are taken up in
nine interesting chapters, and few of the ob-
jects of this class which have been carefully
studied are omitted in the author’s detailed
treatment. A brief final chapter discusses
the physics of the Milky Way.
References to the original sources are faith-
fully given throughout the work, and appa-
rently with few typographical errors, from
which the book is otherwise quite free. We
wish that Miss Clerke would adopt the use of
the convenient word spectrogram instead of
making spectrograph serve for both the instru-
ment and the photographic result of its use.
Slips of the pen seem to be rare, and there are
few points at which a conservative reader
would interpret the results of observations
very differently from the author.
The thirty-one insert plates are for the most
part excellent. Those printed in the text,
except diagrams, are less satisfactory, notably
the picture of prominence on p. 104. The
light weight of the paper makes the handling
of the book a pleasure—and it is likely to
ample treatment.

La Montagne Pelée et ses Eruptions. Par A.
Lacrorx. Ouvrage Publié par |’Académie

téres de l’Instruction publique et des Colo-

plates and numerous text figures.
The most complete report on Martinique yet
published is that of Professor Lacroix, which
embodies the results of his researches during
two extended sojourns in the West Indies.
Few geologists were better qualified to under-
take the task and unusual facilities were of-
fered him to make as exhaustive an examina-
tion as the conditions would permit of the
voleano Pelée.
Professor Lacroix was sent, at the sugges-
tion of the Académie des Sciences, by the
Minister of the Colonies at the head of a
scientific commission to study the effects of
the eruption of Pelée and to examine into its
causes. The commission consisted, in addi-
tion to Professor Lacroix, of M. Rollet de
VIsle and M. Giraud. After a preliminary
visit of little more than a month in June and
July, 1902, the party returned to France to
arrange for a longer visit in the dry season.
The eruption of the thirty-first of August
hastened Professor Lacroix’s departure and
he arrived a second time at Fort de France on
the first of October alone, the other members
of the mission being unable to accompany
him. During this second visit, which lasted
nearly six months, the greater part of the
material was gathered upon which the present
report is based.
Two observatories were established from
which the volcano could be watched day and
night, and at these posts were cameras and
various instruments for the purpose of record-
ing with as minute detail as possible all
events, or changes in the form of the moun-
tain. The results of these observations were
correlated by Professor Lacroix, who devoted
a greater part of his own time to an examina-
tion of the voleano, the collection of speci-

mens, and to obtaining, if one may judge from
the illustrations of the book, a large number
of very remarkable photographs.
In presenting his results Lacroix has ar-
ranged them under three heads: The first part,
which is by far the longest, deals with the
geological and physical problems involved in
the eruptions, and contains detailed descrip-
tions of the more violent outbreaks. The
second part is devoted to a petrographical
study of the actual products of the eruption
and to a comparison of these with rocks from
the other islands of the Lesser Antilles. In
the third part, the various products resulting
from the conflagration of Saint Pierre are dis-
cussed, particular attention being paid to the
secondary minerals developed and the effect of
intense heat on the old andesite of which most
of the houses were built.
Much of the information contained in the
first part will be familiar to those who have
followed Lacroix’s earlier reports and the de-
scriptions of the American observers, but cer-
tain chapters are of unusual interest to geolo-
gists, especially those which deal with the
processes involved in the formation of the
famous ‘dome’ and ‘spine,’ the theory of the
‘burning clouds’ (nuées ardentes) of the
more violent eruptions, the deposits of frag-
mental materials, and the various secondary
phenomena. After summarizing in chapter I.
of the first part the geology of Martinique and
the other Antillean islands, and describing
earlier eruptions, the author calls attention
in chapter II. to the single center of eruption
and the absence of secondary vents. A study
of the modifications in topography resulting
directly from the great eruptions shows them
to have been relatively slight, from a geolog-
ical point of view, when compared with the
devastation wrought. Judging from the reec-
ords of cable repair ships no marked changes
in submarine topography occurred and the
breaking of the cables is attributed to the
shelving of deltas at the mouths of streams
descending from the flanks of Pelée.
In chapter III. Lacroix describes the evolu-
tion of the ‘dome’ and offers an explanation
of the processes involved in its development.
Briefly, the ‘dome’ is the eminence which has
ApRIL 14, 1905.]
appeared within the old crater (Etang Sec)
since the eruption of May 8, 1902, and which
was considered by some of the American ob-
servers as merely a secondary cinder cone, or
an accumulation of fragmental ejected ma-
terial about the actual vent. Lacroix denies
that it is of fragmental nature and states that
it is, in fact, a homogeneous mass of viscous
lava surrounded by an envelope of the same
substance cooled and consolidated. The ex-
planation of this phenomenon and of the re-
markable spine of solid rock which has from
time to time risen above the dome itself is
essentially as follows:
The viscous magma on reaching the surface
through the throat of the voleano and forming
a protuberant mass is quickly surrounded by
a solid shell or envelope which protects the still
pasty interior from a too rapid cooling. This
envelope becomes fissured, under the influence
of progressive solidification, and the increase
in volume of the mass itself, and through the
clefts thus formed fresh molten material is
exuded. In this way a homogeneous rocky
mass increases in height and volume, bristling
with jagged points, glowing like a ‘ charcoal-
burner’s fire’ at night, and bounded by abrupt
walls which rise from the debris accumulating
at its base from incessant superficial crum-
bling. Projected materials resulting from
violent eruptions play but a small part in the
constitution of such a dome. » THE MACMILLAN COMPANY

‘CONE OF THE CLassics OF THE NINETEENTH CENTURY”
The Evolution of Man
A Popular Scientific Study. By ERNEST HAECKEL. Translated
from the Fifth (Enlarged) Edition by JossepH McCasr.
Two volumes, 8vo. With 30 Colored Plates and 512 Other
Illustrations, net, $10.00.
| HIS work is a comprehensive statement of the scientific grounds for evo-
| lution as applied to man. It does not deal with religious controversies,
and is scientific throughont. The work is unique in design, which is
=" carried out with the highest degree of Haeckel’s literary and artistic
skill. Haeckel has always been distinguished for pressing the combination of the
evidence from embryology with the evidence of zoology and paleontology. In the
present work he devotes one volume broadly to embryology, or the evolution of
the individual, and the second to the evolution of the human species, as shown in
the comparative anatomy, zoology and paleontology. The last few chapters deal in
detail with the evolution of particular organs right through the animal kingdom ;
the eye, ear, heart, brain, ete. Every point is richly illustrated from Haeckel’s
extensive knowledge of every branch of biology and his well-known insistence on
comparative study.
The work is written for the gereral reader, all technical terms being explained,
and no previous knowledge being assumed ; but the scientific reader, too, will find
it a unique presentation of all the evidence for man’s evolution and especially as a
study of embryonic development in the light of race development.
In the latest (fifth) German edition, to which Haeckel gave six months’ hard
work, the plan is carried out with great skill, and the illustrations are very fine.
All the most recent discoveries in every branch of science involved are included.
It is a thoroughly up-to-date, non-controversial, most comprehensive and scientific
treatise on the evolution of man by the greatest living authority on the subject.
The English translation is in two volumes, and aims at being especially clear and
useful to the general reader. It contains 30 beautiful plates (most by Haeckel
and generally colored) and 512 engravings (very many full pages) and 60
genealogical tables.

ALBERT BENJAMIN PRESCOTT.
Dr. ALBERT BENJAMIN PRESCOTT, di-
rector of the chemical laboratory at the
University of Michigan, died at his home in
Ann Arbor, February 25, 1905. He was
the senior member of the university faculty,
and one of the veterans of American sci-
ence.
Dr. Prescott was born at Hastings, N. Y.,
December 12, 1832. Educated as a physi-
cian, he took the degree of M.D. in 1864,
and in that year and part of the year fol-
lowing, he served as an assistant surgeon
in the United States Volunteer Army. In
1865 he became assistant professor of chem-
istry in the University of Michigan; was
made full professor of organic and apphed
chemistry in 1870; and was dean of the
school of pharmacy since 1870; and from
1884 to the day of his death, was director
of the chemical laboratory. His whole pro-
fessional life as a chemist was spent in the
service of the university, as teacher, organ-
izer, administrator and investigator dur-
ing a period of forty years.
In a career like that of Dr. Prescott there
is nothing sensational or spectacular. It
was a life of obvious duties, uniformly well
done, with nothing slighted, and no stri-
vings after public recognition. Recognition,
nevertheless, came to him unsought, and he
had the satisfaction of knowing that his
work was appreciated. He became presi-
dent of the American Chemical Society, the
American Association for the Advancement
of Science and the American Pharmaceut-
ical Association ; honors as high as any that
American scholarship can confer. From
602
the University of Michigan in 1896 and
from Northwestern University in 1903 he
received the honorary degree of LL.D.; in
1898 he was made a member of the Ameri-
can Philosophical Society; and in 1904 he
presided over the section of organic chem-
istry in the International Congress at St.
Louis. The list of honors might be length-
ened, but these examples are enough to
show the esteem in which Dr. Prescott was
held by those who knew him best and were
most competent to appraise his merits.
As a teacher Dr. Prescott was singularly
successful, both in his personal relations
with his students and as an organizer of
reforms. He began his work at a time
when lectures and recitations were com-
monly thought to be adequate instruments
for scientific teaching ; and when laboratory
practice for students was a questionable
novelty which only a few American schools
had dared to try. From the beginning he
took his stand on the side of modern
methods, and organized his work along
practical lines. The teaching of chemistry
in schools of pharmacy and medicine was
notably advanced through his efforts; and
given a significance which, in this country
at least, it had not had before. In this
respect Prescott was one of several leaders;
less conspicuous, perhaps, than some others,
because of his modesty and quiet ways, but
none the less potent and influential. He
labored unpretentiously, but the results
which he sought to accomplish were at-
tained. The admirable organization of
chemical work in the University of Mich-
igan is the outcome of Prescott’s broad and
liberal views.
No man ean eseape the influences of his
environment. The work that comes to him
is the work that he must do. In Dr. Pres-
cott’s ease, the requirements of his position
with respect to medicine and pharmacy,
naturally foreed him into the study of or-
ganic compounds, but not along the con-
SCIENCE.
[N.S. Vou. XXI. No. 538.8
ventional lines. Theoretical problems oc- —
cupied little of his attention; but analytical —
methods, especially in the domain of toxi- —
cology, and the investigation of proximate * |
principles, such as the alkaloids, took a
large part of his time. His researches upon |
the alkaloidal iodides, and upon the assay 7
of opium, placed him easily first among
American specialists in that class of stud-
jes. His ‘Outlines of Proximate Organic
Analyses,’ published in 1875, was the first
text-book of its kind in the English lan-
guage, and it brought him an extended
reputation. In the same year he published
a monograph upon ‘The Chemical Exami- f
nation of Alcoholic Liquors,’ which made ; .
him still more widely known. In 1888 he —
issued a ‘Manual of Organic Analysis,’ |
and he also contributed a fair amount to 4
the general literature of analytical proce —
esses. Douglas and Prescott’s ‘Qualitative
Chemical Analysis’ has been a standard
text-book for thirty years.
Dr. Prescott’s position in a state uni-
versity naturally brought him into publie
service in connection with sanitary affairs.
The adulteration of food and the detection
of foreign fats and coloring matters in
butter were subjects to which he gave much {
attention, and in which he was of material
assistance to the food commissioners of
Michigan. Questions of water-supply and
filtration were often submitted to his judg-
ment, and in these ways his public useful- )
ness extended far beyond the limits of his ; ,
state. Unfortunately, work of this kind
brings little glory to a man, but its value
must not be underestimated. It contrib-
utes greatly to the public welfare, and it
can be properly done only by one who is ~
thoroughly faithful and conscientious.
Such a man was Prescott, whose work was
honest from beginning to end.
Dr. Prescott early recognized the value
of research as a means of education, and so
his students often shared in his investiga-

tions.
treated for the destruction of algz. But
there is so much evidence in favor of the
harmlessness of copper that it is impossible
to even refer to it here. After all, it should
be borne in mind that it is not a question
of an absolutely pure water as compared
with water containing a small amount of
copper. It is typhoid- or cholera- or algx-
laden water versus copper water.
When the efficiency of copper for the
destruction of alge had been fully demon-
strated, it became a matter of interest, at
least, to determine the effect of this metal
upon typhoid, cholera and similar disease
germs often conveyed by water. As the
result of a large number of experiments we
were able to determine that while copper
was not quite so toxic to these pathogenic
bacteria as to alge, still the results were
sufficiently satisfactory to make it seem
probable that, under certain circumstances,
the method might prove of considerable
value for the rapid and efficient steriliza-
tion of large bodies of water.
The conditions governing pollution by
alge and bacteria are, of course, very dif-
ferent. ‘Furthermore, there are methods
already in use, which, if properly applied,
Aprit 21, 1905.] SCIENCE. 607
will remove germs from water, whereas
copper, is the only means thus far known
which accomplishes the desired effect with
algee.
_ It should be most clearly understood that
it was not supposed for a moment that the
copper method could be substituted for effi-
cient sand filtration or any other means
now in use which has been demonstrated
as doing the work thoroughly. It was be-
lieved, however, and practical tests since
made have proved it, that in cases where
no system of filtration existed, or where the
filter failed, owing to the storage basin be-
ing flooded by surface drainage, or because
of leakage or other cause, this method was
not efficient, that in copper sulphate we had
the only remedy for such emergency cases.
It should be borne in mind that nothing is
more delicate or requires more intelligent
and conscientious supervision than a filter
plant. Any one who has had an oppor-
tunity to visit many such plants through-
out the country and really knowing their
inside workings, as it were, can not help
being astonished at the low rate of efficiency
frequently maintained. Consequently, the
application of copper sulphate under such
circumstances for the purpose of reducing
the bacteriological content has been used
successfully in enough cases to demonstrate
that it has a distinct place in water purifi-
cation. Whether it would be efficient and
proper to use copper continuously during a
considerable period awaiting the completion
of a filtration system, is a question to be
_ decided by the conditions governing the
case. There is no doubt in my own mind
_ that under certain circumstances such use
is would be justified, and the results would
4 more than repay any outlay of money and
| labor.
_ Others will discuss more particularly the
_ effect of copper upon typhoid, ete., so it is
_ hot necessary for me to refer in detail to
_ the work carried on by the department
along this line. One other point regard-
ing the effect of copper when used upon a
practical seale is of interest, however. That
is, that the theoretical strength, or the
amount of copper used to destroy alge and
bacteria in the laboratory, is considerably
greater than the amount needed on a prac-
tical seale. This may be due to the fact
that the organisms used in laboratory tests
are of necessity more resistant than those
occurring under natural conditions; at any
rate, results show that where it may require
one part in a million of copper to destroy
certain alge under experimental conditions,
it only takes one tenth or even less than this
amount to accomplish the same result in a
reservoir containing millions of gallons of
water.
Dr. Henry Kraemer, Philadelphia Col-
lege of Pharmacy, said: The purification
of water supplies containing pathogenic
organisms being a subject of such vital im-
portance, it seems to me that any method
proposed for this purpose should receive
careful consideration, not only at the hands
of water engineers, water companies, health
officials and physicians, but by all those
who are in a position to test the method, or
contribute information regarding it, or to
foster a sentiment in favor of it if found
to be efficient. It was in this spirit that I
undertook to test the method proposed by
Dr. Moore and Mr. Kellerman.
On account of the false sentiment which
had been engendered in Philadelphia with
regard to the purification of water by
means of copper, and recognizing that the
city authorities would not be apt to apply
the method so long as there was this preju-
dice against it, I determined to consider
the method in relation to its application
for household purposes.
It is, of course, manifestly impracticable
for the average householder to use copper
sulphate in the purification of drinking
water, and my experiments have, therefore,
608
been mostly with metallic copper. I first
tried to obtain copper vessels for my ex-
periments, but finding that I should have
to wait some time to have these made, those
on the market being tin-lined, I decided to
use copper foil instead, which perhaps is
fortunate, as this is more convenient and
less expensive.
In my earlier experiments I had a num-
ber of my students in bacteriology carry
on the work, using pieces of copper foil
about 25 centimeters square to each 2,000
e.c. of water, allowing this to stand from
four to eight hours at room temperature,
the copper foil being cleansed with pumice
for each operation. Agar plates were made
and it was found that there was a reduction
in the total number of organisms of from
85 to 97 per cent. For some time past one
of my special students has been carrying on
this work under my direction, and I may
say that in all of those experiments where
copper has been used the reduction in the
number of organisms has been equivalent
to what would be obtained by an efficient
filtration system, with the advantage in the
ease of the copper treatment that the or-
ganisms are completely destroyed.
In filtration processes it is generally
understood that both typhoid and colon
organisms are the first to be eliminated, and
without waiting to complete a systematic
study of the organisms which persist as
well as those which are killed in the copper
treatment of water, I thought it well to
test the method by using water containing
these organisms alone.
Inasmuch as results depend in some
measure upon the method used, I will try
briefly to outline my method before giving
my results.
1. Water under three different condi-
tions was employed: (a) Distilled water,
which was prepared from tap water by first
treating it with potassium permanganate
and then distilling it two or three times by
SCIENCE.
[N.S. Vou. XXI. No. 538.
means of apparatus constructed entirely of
glass. (b) Filtered tap water, prepared
by means of a Berkefeld filter attached to
a copper spigot. (c) Tap water collected
after being allowed to run through a copper
spigot for five minutes. All of these were
sterilized in an autoclave at 110 degrees for
thirty minutes.
2. The cultures of typhoid and colon
which were used were pure cultures de-
veloped in bouillon for eighteen to twenty-
four hours.
3. To 200 ¢c.c. samples of water prepared
as above, and contained in sterile Erlen-
meyer flasks, were added two three-milli-
meter loops of the fresh bouillon cultures
of typhoid and colon bacilli, respectively.
Counting the duplicate experiments pro-
vided for, we thus had a series of twelve
flasks, six of them containing typhoid ba-
eilli, and six colon bacilli.
4. For studying the number of organisms
1 cc. of the respective solutions was trans-
ferred directly to a Petri dish by means of
a sterile 1 cc. pipette, and to this was
added 10 ¢.c. of Heyden’s nutrient agar
which had been kept at a temperature of
40° C. for some time. Three separate plates
of the water in each of the twelve flasks
were made immediately upon the addition
of the cultures, and both the plates and the
flasks were kept at a temperature of 35°—
37° C. To six of the flasks were then added
strips of copper foil about 15 mm. wide
and 18 em. long, these being corrugated in —
such a manner that the entire surface was
exposed to the water.
5. Plates were made from all the twelve
flasks at the end of four and eight hours,
and one, two and six days, even in the cases
where no organisms remained, and in the
cases where they continued to develop, at
the end of fourteen, twenty-one and twenty-
eight days. The results are given in the
following tables:

SHCTION D, MECHANICAL SCIENCE AND
ENGINEERING.
THE meetings were held in the engineer-
ing building of the University of Pennsyl-
vania. The following officers were elected
to serve during the meeting:
Councilor—¥. W. McNair, president Michigan
College of Mines, Houghton, Mich.
Member of the General Committee—H. §&.
Jacoby, professor of bridge engineering, Cornell
University, Ithaca, N. Y.
Member of the Sectional Committee, 1905 to
1910—A. M. Greene, Jr., professor of mechanical
engineering, University of Missouri, Columbia, Mo.
The secretary of the section was elected
press secretary; vice-president and chair-
man of the section D. S. Jacobus, professor
of experimental engineering, Stevens Insti-
tute, Hoboken, N. J., was forced to be ab-
sent, owing to illness in his family. The
sectional committee appointed Calvin M.
Woodward, ex-vice-president of the section,
to act as chairman of the section for the
meeting.
The program had been arranged so that
papers pertaining to civil engineering,
mechanical engineering, metallurgical en-
gineering and general engineering, and
to engineering education, should be read
at separate sessions. The program of
Wednesday morning, December. 28, was de-
voted to civil engineering. The first paper
on the program was by C. G. Elliott, expert
in irrigation and drainage investigations
of the Department of Agriculture, Wash-
ington, D. C., and was on ‘Irrigation and
Drainage Investigations of the Department
722
of Agriculture.” He showed that while
chemical analysis may show that two soils
are equally rich in plant food, yet on ac-
count of unfavorable water conditions, one
of them may be quite unproductive, and
the different portions of even the same
field may vary in their production on ac-
count of differences in the water content of
the soil. The supply of water and the con-
trol or regulation of its quantity in soils of
different classes under varying climatic
conditions for the production of crops of a
first-class character present an important
field which now occupies the attention of
the irrigation and drainage investigations.
The objects of this work are to ascertain
the best methods and provoke their, use in
applying water to soils where it is deficient,
conserving and regulating its quantity, re-
moving surplus from saturated soils and
reclaiming and protecting lands from over-
flow, all of which invokes a variety of en-
gineering practise. The soil water neces-
sary for the growth of plants is held about
soil drains in films and is removed from the
soil by ecapillarity, plant absorption and
surface evaporation only. Irrigation must
supply this amount when deficient, and
any surplus must be removed by drainage.
The water-holding capacity of different
soils is an important subject for investiga-
tion: The part of the engineer. is to pro-
vide means for supplying, regulating and
controlling the soil water to meet the needs
of the various kinds of soils encountered
and plants grown therein, and includes a
study of the movements of water, both by
eapillarity and by gravity.
Henry S. Jacoby, professor of bridge
engineering, Cornell University, Ithaca,
N. Y., presented ‘Some Notes on Rein-
forced Concrete Arches,’ giving the results
of his study and investigations during the
past year and supplementing his previous
papers.
E. J. MecCaustland, assistant professor

in civil engineering, Cornell University,
Ithaca, N. Y., next presented a paper on
‘Tests of Reinforced Concrete Beams,’ in
which he presented the data and conclu-
sions obtained from the tests to failure of
twenty-three beams of concrete, reinforced
by plain and various forms of patented
bars of steel. They were 6 by 8 inches in
size and 6 feet long. Plain square steel
rods were used, varying in sizes from 2 to
# ich and placed either 14 or 2 inches
from the lower face of the beam. The
beams were made of a very lean concrete
(1 cement, 2.5 sand and 9 broken lime-
stone), so that in all cases the steel rein-
forcing bars developed full strength of the
conerete before reaching the elastic limit.
Deflections were measured, and also the
extensions of the lower fibers. 3); on thermal

action of histones. The essays for 1905 and
1906 are to be sent in by August 1 of the
respective years, and the prizes range from
$120 to $200 in value. In addition, prizes be-
queathed by Edward Mailly and in memory
of Louis Melsens are offered under the usual

istry or physics respectively.
UNIVERSITY AND EDUCATIONAL NEWS.
Tue cornerstone of the library building of
Leland Stanford Junior University was laid
on May 15. The building will cost $800,000.
At the ceremonies an address to the students
by Mrs. Stanford was read. In it she makes
the amount. realized from the sale of her
jewels, which are estimated to be worth $500,-
000, an endowment fund for the library.
Grapuates of Yale University have arranged
to purchase for the university the Hillhouse
840
estate, containing thirty acres and costing
$510,000. This purchase fixes definitely the
direction of Yale’s growth northward beyond
the present site of the Sheffield Scientific
School.
Ir was announced at the meeting of the
Yale Corporation, on May 15, that a gift
had been received by Yale from a Harvard
graduate—whose name was withheld—for the
purpose of cementing the good feeling between
the two universities. The use of the fund
was left entirely to the Yale Corporation,
which has voted to expend it for securing from
time to time lecturers from Harvard to speak
before the students of Yale. President Eliot,
of Harvard, has accepted the corporation’s
invitation to be the first lecturer.
Tue University of Indiana has been granted
$100,000 by the state legislature for the erec-
tion of a new library.
Work is about to be started on the new sci-
ence hall of Colby University, which will be
erected at a cost of about $90,000.
Dr. D. K. Pearsons, of Chicago has made
a gift of $50,000 to Montpelier Seminary at
Montpelier, Vt., which he attended, conditional
upon the institution raising $100,000 within a
year.
Ar the annual meeting of the National
Academy of Design it was voted to accept the
offer of Columbia University to form an affilia-
tion. It is planned to collect $500,000 for a
building, which will be erected on a site fur-
nished by Columbia University.
Tuer University of North Dakota will open
a medical college in the autumn of 1905.
Until the clinical advantages are adequate the
medical course will extend only through the
first and second years of the four years’ cur-
riculum. Students who have completed the
work at the University of North Dakota will
be received into the junior year of the medical
schools with which articulation is arranged.
The Medical College at Bahia, Brazil, with
its equipment and valuable library, has almost
totally been destroyed by fire.

been somewhat curious. Students who have
done their work at Oxford or Cambridge may
receive the bachelor’s degree at Dublin. As is
well known, Oxford and Cambridge do not
give their bachelor’s degree to women, and
eighty-four women who had completed the
work for the degree at these universities have
received the degree from Dublin on the pay-
ment of $50 each.
Proressor AsapH Hatt, Jr., has resigned as
professor of astronomy and director of the ob-
servatory at the University of Michigan. Pro-
fessor W. T. Hussey, of the Lick Observatory,
has been elected his successor. Professor
Hussey was graduated from Michigan in 1889.
SaMuUEL J. BarNeETT, assistant professor of
physics at Stanford University, has accepted
the chair of physics at Tulane University,
vacant by the resignation of Dr. Brown Ayres
to accept the presidency of the University of
Tennessee.
THE department of physics in the Univer-
sity of California has secured the appointment
of Dr. A. S. King and Dr. A. W. Gray for
the coming year, as instructors. Dr. King
will continue the spectroscopic investigations
on which he has published already a number of
papers. Dr. Gray returns from the Univer-
sity of Leyden, where he has been working in
the cryogenic laboratory, to a ‘ Research In-
structorship on the Whiting Foundation,’ sup-
ported from the income of the bequest of
Harold Whiting, formerly associate professor
of physics in the University of California.
Ar Williams College, Mr. William E. Me-
Elfresh has been promoted to the Thomas T.
Reed professorship of physics, and Mr. Herd-
man L. Clelland to a professorship in geology.
Dr. E. B. Hour has been appointed assistant
professor of psychology at Harvard Univer-
sity.
Dr. A. R. FERGUSON, senior assistant to the
professor of pathology in Glasgow University,
has been appointed professor of pathology in
the Medical School, Cairo.

An Educational Magazine of interest to all serious students of education.
Some of the ablest contributions now being made to educational
literature are appearing in the JouRNaL oF PeEpacocy.
A REPRESENTATIVE OPINION
“Tn building up the occupation ot teaching till it becomes a true profession,
no magazine is rendering more significant and vital service than the JOURNAL
OF PEDAGOGY, which admirably displays the interest of the editor in the science
and art of education. Its articles have always been noteworthy for their
Strength and freshness; its book reviews have been conspicuously valuable,
exceeding in number those of the several other leading magazines combined.
No field of educational effort has been neglected ; and there has been a reason-
able apportionment of space alike to the university, the high school, the
elementary school, and the kindergarten. Those who are earnest for the better-
ment of American education view with the greatest seriousness the endeavor
of such a magazine as the JOURNAL OF PEDAGOGY to represent the best thought
and practice of the times, and by representing that thought and practice to
encourage their influence. To publish such a periodical is a noble enterprise
tor the welfare of American schools and of the American nation.’’—Dr. W. E.

THE PHYSICIAN OF THE FUTURE.*
Tue day which marks the beginning of
a career is always one of interest. Espe-
cially is this so for him whose career begins,
if indeed a career can be said to have
definite commencement. But little less of
interest, however, is felt also by his friends,
and the day partakes of the nature of an
Inauguration or a marriage. It is a gen-
eral day of rejoicing. The graduate him-
self is happy in the thought that his labors,
at least for the time being, are over; his
friends are glad to see the honor which he
has earned, and the general public takes
almost the same interest in the graduate
that it does in the lover.
This particular occasion, when those who
have completed the prescribed course of
medical and dental science present them-
selves to receive their degrees, is of especial
interest. This probably marks the last
commencement of the medical and dental
school of old Columbian. More than three
quarters of a century of achievement
marks her suecessful career. Thousands
of graduates scattered throughout the land
are proud of the alma mater who started
them in life. The change of name, there-
fore, to George Washington University is
not looked upon with unmixed joy, espe-
cially by the older children. A mother
is, perhaps, no less a mother because, when
widowed, she marries another man and
takes another name. The academic mother

of this widely scattered and numerous
family need be no less loved, no less
cherished and no less helpful than under
her old name.
There are some of the arts which are
nearer to the welfare of man than others,
and the same is true of the sciences. There
are two arts, however, which lie very near
human welfare and if we were called upon
to give up all of the arts but two, I think
there would be little difference in choice as
to which two should be preserved. The
one most important would be the art of
agriculture and the next the art of healing.
Man first of all must be nourished and next
to this, kept in health.
We might look forward to a time when
lawyers would disappear. We might even
grow so perfect as to be able to do without
ministers of the gospel. Even the. his-
trionic art might be abandoned, and yet
mankind be reasonably happy. But strike
down agriculture and you strike a blow
which is fatal; banish the healing art and
you leave man to the ravages of disease.
It is, therefore, probably not without some
fitness that you have asked a ‘farmer’ to
deliver this address, and it is quite becom-
ing that on this occasion Ceres and Hygeia
should be seen hand in hand.
The man who receives his degree believes
he knows something and the puble sup-
poses that his belief is well founded. The
amount known, however, or supposed to be
known, varies greatly for different degrees.
The college graduate, it has been said,
doubtless supposes that he knows all things
from A to Z, but the faculty and trustees,
with a better idea of his accomplishments,
give him only the degree A.B. If I re-
member aright my Roman numerals an
M.D. should know at least 1,500 times more
than an A.B. Yet without doubt the de-
gree M.D. or D.D.S. should carry a greater
ballast of knowledge than the first degrees

of the academy. We may, with reason,
doubt the propriety of conferring the de-
eree of ‘doctor’ even upon those who have
accomplished as much as you young men
who are now before me. Doctor signifies
‘knowing,’ ‘learned.’ The physician
should not—and perhaps no one should—
bear this degree who has not added some-
thing to the sum of human knowiedge.
Some of the most famous surgeons and
physicians of England ‘are only plain
‘mister’ and I fail to see where there would
be any diminution in your skill if the
degree which you receive to-night were
‘pachelor’ instead of ‘doctor.’ I am not
quarreling, however, with the usual cus-
tom, but mention this matter only to show
you that bearing this degree you assume
a responsibility of which you must strive
to be worthy. The doctor is the teacher,
the learned man, the knower as well as the
doer. He is the man to whom people must
come for knowledge, advice and inspira-
tion. He is, moreover, the dua, the
imperator in the empire of knowledge.
Like the thirsting Omar Khayyam, each
one should be able to say, ‘Myself when
young did eagerly frequent doctor and
saint and heard great argument,’ but the
doctors and saints should be of better
quality than in those medieval days, for
in the present day we should not be com-
pelled to add, ‘About it and about but
evermore, came out by the same door as in
I went.’
Health comes largely from good food
and good hygiene, but one of the neces-
sities to health is good mastication. Teeth
are useful for other purposes than merely
to improve looks, but even if they were
only for this purpose they would be worth
saving. Many a man has married @
beautiful set of teeth and, perhaps, after-
wards discovered, to his amazement, that
they were the fruit of dental science, but
—
a
JUNE, 2, 1905.]
you young men who have studied dentistry
and have beeome proficient in the art
should think the making of teeth to be the
least of the purposes of your future life.
As in surgery, dentistry is conservative,
and you will serve man best if you will en-
able him to keep the teeth which nature
has provided. The physician of the fu-
ture as well as the dentist must be the
arbiter of good health, and good health
eomes largely from good food and good
hygiene; good food well masticated and
good hygiene well applied.
The farmer furnishes the food, the
dentist secures its mastication, and the
physician formulates the laws of health
and helps to restore to the normal any dis-
eased organ of the body. The first thing,
therefore, which the physician of the future
must see to is the food supply, not that he
is expected to till the soil and produce its
fruits, but that he is to help in the great
work of restoring foods to their normal
state.
To what lengths have the arts of adulter-
ation gone? There is no time to-night to
preach to you about the awful evils of food
adulteration, not only of its effect upon
health, but of its demoralizing effect upon
the honesty of commerce. It is a matter
of which the medical profession of this
country may be proud, namely, that as a
unit they stand committed to the cause of
pure food, to opposition to fake advertis-
ing, to the restoration of honesty in the
trade in food products, and to the elimina-
tion from foods of drugs which are useful
only in eases of disease. The great army
of dentists also in this country stand in the
same rank. They are aware, in fact, that
if the functions of an organ are suspended
the organ itself sooner or later suffers
atrophy, loses its power of functional ac-
tivity, becomes abortive in the course of
ages and rudimentary. Thus the great
SCIENCE.
843
professions of medicine and dentistry in
the future will stand together to fight the
evils of predigested and prechewed foods.
Predigested food will cause the stomach to
shrivel and become finally only a rudi-
mental organ. Prechewed food will in the
course of ages produce a toothless race.
It is bad enough to lose one’s hair, but for
heaven’s sake let us keep our teeth!
I do not care who makes the laws in this
country if you will let me furnish the
people with good teeth, nor who writes
the songs if I can help to keep the stomachs
in prime condition. It will be a sad day
for humanity in the future when pepsin
loses its savor and is furnished only by the
chemist and not by the secretory glands of
the stomach. See to it then that future
generations have something to chew and
something to digest, and’ to this great end
much of the energy and ardor of the in-
vestigations of our future physicians and
dentists must be directed. |
The physician of early ages was a
magician and necromancer. The medicine
man of savage tribes is still practising the
art of incantation. It is a far ery to
Adseulapius, but before his day even dis-
ease was supposed to be the work of evil
spirits. In fact the most destructive swine
plague that we read about in the Bible was
caused by the devils which were east out of
sick men, and these devils, taking posses-
sion of the swine, caused them to rush into
the sea and be drowned.
The age of magicians in medicine was
followed by that of the empiric, which was
a great advance and led to the foundations
of real science in medicine. The empiric
we still have with us and always will have
as long as man has idiosynerasies. We
ean never tell in any individual ease what
the result of any certain treatment will be
because we can never properly estimate the
value of the individual idiosynerasy.
S44
Empiricism is one of the legitimate aids
to science. A great inventor like Edison
who wishes to find a certain property tries
in logical sequence everything that is prac-
ticable, and often it is only after thousands
of trials that the substance having the
requisite quality is found. So empiricism
in medicine is legitimately applicable when
guided by scientific reasoning and sound
principles.
The age of empiricism, however, was fol-
lowed by the age of rationalism in medicine
and it is on this basis that the science of
medicine stands to-day. Perhaps I should
not say science of medicine, but the art of
medicine, because the art of medicine itself
is based upon certain sciences, for instance,
the science of anatomy, of physiology, of
materia medica, of surgery. In fact there
is not a science known to man which may
not have some connection with the art of
medicine.
If we look at the physicians of the pres-
ent we find three classes have been founded
as a result of rationalism in medicine:
First, the general practitioner who of neces-
sity must be brought in contact with all
forms of human ills; second, the specialist
who happily lives in a community where
the physician who devotes his whole time
to one particular study can be supported;
third, the health officer who is the fore-
runner of the physician of the future.
The foes of rational medicine at the
present time are, first, the quack, a man
possessing, possibly, high medical training
and skill, but unfortunately devoid of those
principles of ethies without which the hon-
orable practise of a profession is impos-
sible; second, the charlatan, a man neces-
sarily devoid of any medical training or
ability, who plays upon the feelings of his
patients and administers nostrums of no
value and applied with no science. The
third foe of rational medicine is the imper-
SCIENCE.
[N. 8. Vou. XXI. No. 544.
sonal physician, namely, the nostrum, the
patent medicine and the proprietary rem-
edy. It is appalling to think of the thou-
sands and thousands of our fellow citizens
who pin their faith to these alleged reme-
dies. Some of them have value; they are
in fact often the very remedies which are
described in the materia medica and the
pharmacopeia and administered by physi-
cians, but distributed as they are, with
absurd claims of efficiency, taken as they
are, without the advice or consent of a
physician, they become not only one of the
greatest foes of rational medicine, but one
of the greatest dangers to the public at
large.
I do not deny to the inventor who dis-
covers a new remedy or a new combination
of remedies the same right to profit there-
from which is accorded to the inventor of
a new machine or a new process. The law
protects the inventor of such a remedy and
he can protect it by patent or by trade-
mark, but it seems to me there is no excuse
for the secret nostrums and no justification
for the methods of advertising them. I
know how difficult this problem is; I know
what vast returns are received by the pub-
lie press for advertising these bodies; I
know how valuable the press is and I ap-
preciate the great and good work which it
does, but there is no justification for using
the columns of the public press to deceive
the public, to excite fears of dangers that
do not exist and create hopes that can never
be realized.
The physician of the future will see a
growing preponderance of preventive medi-
cine and the character of the profession in
future years will be largely molded by the
influence which this growth exerts.
The activity of preventive medicine will
be shown first in the case of public and
domestic hyg:ene. The laws of good living
are fairly well known to but few people.
June 2, 1905.]
The public schools will surely become a
medium of transmitting instruction in this
line. Public sanitation in the course of its
eareer may reach that abomination of con-
trivances in so far as offended hygienic
conditions are concerned, namely, the sleep-
ing car. It is difficult to imagine any con-
trivance which human ingenuity could con-
struct better caleulated to secure the best
conditions for disease and the best methods
for propagation thereof than the sleeping
ear. Constructed in such a way that ven-
tilation is practically impossible; parti-
tioned into small compartments, carefully
curtained to prevent any circulation of air,
if there should be fresh air; provided with
enough heating surface to the cubic yard
to complete the installation of a Turkish
bath, and manned by porters to whom high
temperature is an evidence of heavenly
bliss, it is not difficult to conceive of the
tortures to which the helpless passenger is
exposed. These compartments often carry,
without any precautionary inspection, per-
sons in all stages of phthisis and even other
contagious diseases. There is no health
officer to inspect Incoming passengers, no
provision of the law requiring complete
fumigation and no systematic appliance of
any kind to prevent or eradicate disease.
It has been claimed that the blankets are
washed at least twice a year, as if that
alone were a sufficient excuse for all of the
dangers that exist! Perhaps, if one used
the same blanket himself all the time he
might not be justified in objecting to such
frequent ablutions, but what right have we
to ask if such a careful purification of a
blanket used by a different person every
night is based on any of the broad prin-
ciples of hygiene or good taste?
The composition of the air in a sleeper
filled with passengers, after a night of low
temperature can better be imagined than
described. It is true that no one is com-

pelled to spend the night in these ecompart-
ments, but the ordinary coaches are not
much less objectionable, and thus the
traveler is left only with the option of
staying at home or walking to his destina-
tion.
The physician of the future will gradu-
ally teach the people the principles and
necessity of public and private sanita-
tion, for domestic hygiene is no less impor-
tant than public. That dread scourge of
humanity, consumption, will find its most
effective foe in the establishment of true
principles of hygiene both at home and in
public places. ‘
The medical profession of the future will
also see extended and placed upon sounder
scientific foundations the antitoxin theory
of prevention and cure. The world owes
a debt of gratitude to Pasteur and his
co-laborers in this and other countries
for establishing the foundation, on broad
scientific grounds, of the idea that im-
munity may be artificially, as well as nat-.
urally, produced. Jenner was the fore-
runner of this great school of medicine,
but his practise was absolutely empirical.
Neither he nor his followers had any idea
whatever of the manner in which vaccina-
tion renders the subject practically im-
mune to smallpox. Advanced medieal sci-
ence has revealed the fact, however, that
not only smallpox, but many other deadly
diseases owe their toxic development to the
compounds produced in the system chem-
ically allied with the nitrogenous constitu-
ents of the body. The moment these poi-
sons become dominant in the system nature
makes an effort to eliminate them or to
neutralize them. In other words, the toxic
body is met and combated by the antitoxic
body. One of the greatest triumphs of the
science of chemistry has been the deter-
mination of the character both of toxic and
of antitoxie substances and the development
846
of the method of producing them both, es-
pecially the antidote. You have been fully
instructed in the principles of this modern
branch of medicine and know how closely
your future professional activity will be
connected therewith.
Perhaps it is not wise to prophesy a time
when enzymic diseases shall lose all their
terror by reason of the discovery of ef-
fective antidotes to the poisons to which
their ravages are generally due. It is rea-
sonable, however, to look forward to the
time when the terror of these diseases,
namely, diphtheria, typhoid fever, typhus
and kindred scourges shall be reduced to a
minimum.
If, as has been well demonstrated, the
germ of typhoid fever is transmitted prin-
cipally in water, there seems no reason to
doubt the ability of health officers, collabo-
rating with broad-minded municipal au-
thority and high class engineering skill, to
perfect means whereby this deadly germ
shall be practically eliminated from our
water supply. Consumption may be
checked by the establishment of camps of
detention where the unfortunate victims of
this terrible disease may receive not only
the highest degree of proficiency in medical
treatment, but also be so segregated from
the non-infected portions of the community
as to render the spread of the disease diffi-
cult.
Moses himself was a sanitarian of no
mean accomplishments and many of the
principles established by him in sanitary
science might well be exploited in modern
times. The type of camp which he estab-
lished for the detention of unfortunate
lepers, well modified to suit modern prin-
ciples, would serve for the check and prac-
tical elimination of consumption.
I realize vividly the effect of a mental
nature produced upon people of highly
sensitive constitutions and of an impres-
SCIENCE.
sionable nature, such as the victims of
phthisis usually are, in being made prac-
tically prisoners in an environment of
misery and despair. This, however, is not
a question of sentiment, it is a principle of
existence. It is based upon the undoubted
right of the healthy to be protected against
the invasion of disease. Moreover, a deten-
tion camp might be made attractive in
every way with beautiful gardens, sun-
shine, flowers, music and all the other
agreeable arts of life, and thus the terrors
of detention be robbed of their chief sig-
nificance.
The physician of the future will, there-
fore, be the herald and exponent of pro-
phylaxis. It seems a contradiction of
terms to predict a future for a learned pro-
fession, which, if perfected, would rob the
profession of all of its emoluments; but
with the changed condition of the future
physician a change in the character of his
emoluments will also come. The medical
profession, in other words, will not be paid
in proportion to the amount of sickness -
which prevails, but rather in proportion to
the degree of health which is maintained.
That physician will have the largest com-
pensation whose parish is freest from dis-
ease. He will become the teacher of the
principles of public hygiene, as before men-
tioned, in the schools, colleges and hos-
pitals; he will, in my opinion, become
largely a public officer, and every state, city
and town will have as one of its chief offi-
cials a medical health officer. Surely such
an officer is quite as important to the wel-
fare of the community as the assessor and
tax collector. The physician of the future,
therefore, will become more and more active
as a citizen and take a more lively interest
in public affairs.
I have looked carefully over the congres-
sional directory of the Fifty-Seventh Con-
eress and find that the congress of the
[N.S. Vor. XXI. No. 544,
a I NI
JUNE 2, 1905.]
United States contains 319 lawyers, 93
business men, 32 politicians, 12 editors, re-
porters and newspaper writers, 8 farmers,
3 teachers, 1 clergyman, 1 military man
and 38 physicians. Does it not seem
strange that the great law-making body of
our country should contain so few mem-
bers of this learned profession? Think for
a moment of the amount of legislation in
which sanitary matters are involved! It
is acknowledged by all that the building of
the Panama Canal is more a sanitary prob-
lem than it is an engineering one. The
men who really build the Panama Canal
will be the physicians and health officers
who eliminate from that infected locality
the germs of malaria and infectious dis-
eases. If the canal fails it will not be for
lack of dredges nor shovels nor picks nor
machinery nor money; it will be due to
the ravages of cholera, of yellow fever and
of other malarial diseases.
The importance of the quarantine serv-
ice has not been fully recognized. The
exclusion of disease is the easiest way to
fight it. The splendid work of the Publi
Health and Marine Hospital Service is one
of the things which the national legislator
should carefully support.
The legislation relating to pure food is a
matter of the utmost sanitary importance.
The regulations of interstate commerce
which omit the sanitary conditions which
have been previously outlined are alto-
gether incomplete. In fact it appears that
a very large proportion of our legislation
which really concerns the public welfare
should be accomplished with the advice,
the vote and consent of the medical pro-
fession, and yet out of more than 400 mem-
bers of the national congress only three
have had any medical training. The con-
gress of the future will contain not less
than 1 per cent. of trained medical men,
but let us hope as much as 25 or 30 per
SCIENCE.
847
cent. Again, there is no reason why a
medical training should unfit a man for
other duties in connection with public life
than those relating to sanitary measures.
I can see no reason why a physician should
not make a good president as well as a good
major general, a good governor or a good
mayor, a good member of the common
council and especially a most excellent
commissioner of sewers. We wish the fu-
ture to see the entry of medical men into
public life and the assumption by them of
all duties of a nature which relate to the
public welfare. I can see no reason why
lawyers should predominate in our national
congress any more than that physicians
should hold the. balance of power. Perhaps
I can not better illustrate this idea than
by quoting from that master of political
craft, that learned and erudite statesman,
ex-Senator David Turpie, who says in his
book, entitled ‘Recollections of My Own
Times,’ in speaking of Senator Dr. Gra-
ham N. Fitch:
Fitch was the only physician who ever served
from Indiana in the United States Senate. I
have latterly reflected somewhat upon this solitary
instance. Years ago we used to send a good many
of our physicians to Congress. He, himself, was
one of these, and there were several others, among
whom I recall Dr. John W. Davis, of Carlisle, in
the county of Sullivan, whom I knew quite well.
He was the first Indianian chosen to the position
of speaker of the House at Washington and was
accounted the best parliamentary jurist in the
country, perhaps in the world. His rulings were
quoted as authority in the English House of
Commons and more than once in the legislative
chambers of France. Upon his voluntary retire-
ment from Congress he was appointed minister of
the United States to China; served with distinction
among the polished diplomats of the Orient, and
returned to accept the appointment of governor
of Oregon. He was the first American civilian
of official note and station to make the trip home-
ward from the east by way of the Pacific. His
voyage across the ocean lasted several weeks.
I have heard that the account of it, then no twice-
told tale, was a story of thrilling, almost tragic
interest.
848
In these later times our practitioners of the
healing art seem studiously to avoid the cares and
labors of political life. Occasionally you may
meet a physician in the legislature—even this, as
some of their caste say, is unprofessional—but as
a body they appear to prefer the position of out-
fielders in this arena. There are two notable
characteristics of the active and skilled physi-
cian—a close observation of detail and a deft
attention to the matter in hand—the duty of the
hour, of the moment. These qualifications are
admirably suited to the requirements of public
life. No more favorable hope can be expressed
for the future than that the members of this great
profession will again resume an active interest
and prominent position in the political affairs of
the state and nation.
The physician of the future will have
no easy berth, for, in his profession, as in
all others, fitness, tact, erudition and in-
dustry must win the way. The sluggard,
the ignoramus and the indifferent must
fall by the wayside.
The number of people entering the med-
ical profession is probably too great. In
the United States of America, including
the Philippines, Porto Rico and Hawaii,
there were in 1901, 115,222 physicians in
a population of 84,332,610. The last com-
plete data we have concerning the number
of attendants in medical schools are for
1899. In this year there were, excluding
graduate schools, 156 medical schools in
the United States with 24,119 students.
The growth in the number of medical stu-
dents in twenty-one years has been 142
per cent.
In addition to these undergradute schools
there are eight graduate medical schools
which had (in 1895) 624 instructors and
1,813 students, of whom 59 were women.
In Germany the conditions are quite un-
satisfactory and the overcrowding of the
medical profession in that country is a
matter of grave concern. There are now
in the empire 29,200 physicians, which
doubles the number found in 1876. In
other words there is one physician in Ger-
SCIENCE.
(N.S. Von. XXI. No. 544,
many for every 1,700 inhabitants. In the
city of Berlin 46 per cent. of all the physi-
cians have an income of less than $700,
and five per cent. of the whole number do
not have a sufficient income to return it
for taxation.
On the other hand, in the iegal profes-
sion in Germany 80 per cent. of the lawyers
have an income exceeding $2,000.
It is estimated that the preparation of
a man for the duties of a physician in Ger-
many costs about $6,000, and thus it is
seen that the income is often less than 10
per cent. of the fixed charge on the capital
invested. This leaves practically nothing
for the reward of his own personal sery-
ices, nor for wear and tear.
What are to be the remedies for this
condition of affairs in the future? Shall
the physicians organize a union and admit
only a certain number of apprentices each
year, or shall they have the requirements
for admission, when properly applied, ex-
clude all those who are not extremely well
prepared? In the- great school of the
Beaux Arts in Paris the number of ad-
missions is strictly limited and, perhaps,
the great world school of medicine will
have to come to this condition of affairs.
In fact, an approach has been made al-
ready in at least one great medical school
of this country, and candidates for the
degree of doctor of medicine are not ad-
mitted until they hold a previous degree
of an academic character or study equal
thereto equivalent to the course of study
required for the ordinary degree of
bachelor of arts. The effect, however,
which was anticipated in this particular
instance was not realized. Indeed, there
was at first a diminution in the number of
students in attendance, but, attracted by
the greater fame which a degree from such
an institution would afford, this condition
was gradually overcome and the actual
}
JunNE 2, 1905.]
number of attendants became greater than
when admission was easier.
This is indeed a serious question. I
doubt if the charge for medical services in
the country can be much larger than $1.00
per head, and it is thus seen that the
115,000 physicians of this country must
be content to divide among them a paltry
income of less than $90,000,000 at the
present time.
Finally, the physician of the future will
find his greatest service in prolonging hu-
man life. JI am not here to claim that
human life is so valuable that it needs
always to be prolonged. This may not be
so from the general economic condition of
affairs, but, personally, I think we are all
more or less interested in longevity. It
ean not be denied that there is a distinct
economical gain in putting a man out of
the world after he has passed his prime
and before be becomes a burden upon his
friends or the community. The asylum
and the poorhouse are not to be regarded
as shining lights of advanced political econ-
omy, but there is something in life besides
mere political economy, and the prolonga-
tion of existence is regarded as one of the
chief functions both of the medical pro-
fession and of public charities.
On the other hand, it must be considered
that there is a distinet economical loss in
eutting off from existence a man before he
has run the full course of his career. To
train a man for usefulness requires now
fully a quarter of a century, and it seems
onty fair that he should have at least twice
that time for the manifestation of his ac-
tivities. If, therefore, he be cut off at
thirty-five, forty or forty-five, the com-
munity is robbed of service to which it is
entitled.
If old age could be secured without much
of the burden now attending it, there would
be the gradual ripening and mellowing of
SCIENCE.

all the functions of the body and mind.
If, in short, the human organism could be
so constructed and eared for that it would
continue its functional activity like the
wonderful ‘one hoss shay’ until the time
of its final dissolution, such a consumma-
tion is devoutly to be wished.
The medical profession of the future
will find its best exponent in the service of
senectitude. An old age without illness
or dementation, a ripening without decay,
a completion of the functional activity
without the breaking down of any organ
are steps toward which the medical pro-
fession of the future may well direct its
energies.
Death should not be regarded as a mis-
fortune, but as an end, as a termination
of a journey which has been filled with
delight, as a rest for weariness which comes
with the natural order of labor, as an
euthanasia and not a dreadful disaster. _

The following are titles and abstracts of
papers presented at the meeting:
The Origin of the Sex-Cords and Rete-
Cords of Chrysemys: BENNET M. ALLEN,
University of Wisconsin.
In an early stage of development (em-
bryo of 7 mm. total length), each of the
more ventral Malpighian corpuscles of the
mesonephros is still attached to the peri-
toneum by a neck of cells which sometimes
possesses a lumen and constitutes a perito-
neal funnel. There are usually four, some-
times three, such Malpighian corpuscles
in each somite. A peritoneal ingrowth arises
either directly from the base of each peri-
toneal funnel or just mediad of it. These
ingrowths are termed funnel sex-cords.
Other sex-cords arise from the peritoneum
between the funnel sex-cords and the mes-
entery. These anastomose with the funnel
SCIENCE.
[N.S. Vou. XXI. No. 544.
sex-cords which in turn unite with evagina-
tions from their ¢orresponding Malpighian
corpuscles after the latter have broken
away from the peritoneum. The bridges
thus formed between the funnel sex-cords
and Malpighian corpuscles constitute the
rete-cords which are thus formed from the
distal portions of the funnel sex-cords plus
evaginations from the Malpighian corpus-
cles. The foregoing applies to the sex-
gland along its entire length.
The distal ends of all the funnel sex-
cords and of many of the other sex-cords
contribute to the formation of the adrenal
bodies.
The anterior portion of the sex-gland of
the turtle is homodynamous with the rete
region of the genital ridge of the mammals
(pig and rabbit).
Further Notes on the Chromosome Com-
plex of Orthopteran Spermatocytes: C.
E. McCuune, University of Kansas.
A careful study of a large number of
species indicates that the members of a
family possess a common number of
chromosomes. Im each species there is
found a characteristic series of chromosome
forms, and these are in many eases pecul-
larly associated. In some cases the group-
ing is characteristic of the genus, and
within the genus the species are marked by
variations in size of chromosomes and other
parts of the cell. Heterotypical mitoses
occur in spermatogonia, first spermatocytes,
and second spermatocytes, and in each case
witness a longitudinal division of the
chromatin thread. In the spermatocytes
all the chromosomes do not divide in the
same manner. These irregularities of asso-
ciation and division are largely due to the
action of the accessory chromosome, which -
in some eases unite with the one tetrad,
forming a trivalent element, and in others
with two tetrads, producing a pentivalent
mutiple chromosome. From these observa-
JUNE 2, 1905.]
tions it is concluded that generic and
specific characters are the result of differ-
ences in size and associations of chromo-
somes, and not to variations in numbers.
It is also thought that continuous variation
may be due to slight differences in size of
the chromosomes of the germ cells, while
discontinuous variation would be due to
alterations in the relations of chromosomes
to each other.
Regeneration in Nudibranchs: C. M. Cup,
University of Chicago.
Several species of wolids abundant in the
Pacific Grove region were used for experi-
ment.
It was found that removal of a portion
of the body posterior to the middle was fol-
lowed by rapid regeneration. The larger
the portion removed the more rapid the
regeneration.
The ganglionic mass is situated posterior
to the second pair of tentacles; removal of
the whole head anterior to the ganglia was
followed by rapid and complete regenera-
tion. When the ganglia were removed no
regeneration beyond healing of the wound
occurred, though the animals often lived
for two weeks.
Regeneration of posterior portions of the
body was less rapid in specimens from
which the head anterior to the ganglia had
been removed than in specimens with unin-
jured head. The specimens from which
the head region had been removed had lost
their principal sense organs, but still re-
tained the central nervous system intact.
They were much less active than specimens
with normal heads and the posterior parts
were consequently subjected in much less
degree to the conditions accompanying
functional activity of this region; hence in
all probability the less rapid regeneration.
After the new head regenerated, posterior
regeneration in these pieces was fully as
rapid as in those with uninjured heads.
SCIENCE.
851
Removal of other portions of the body such
as the lateral regions of the foot, ete., had
no effect upon the rapidity of posterior
regeneration.
If the animals are not fed a marked re-
duction in size, often 50 per cent., occurs in
the course of two or three weeks.
The Relation of the Degree of Injury to
the Rate of Regeneration: CHARLES
ZELENY, Indiana University.
Two series of the crayfish, Cambarus
propinquus, differing only in the degree of
injury which they had sustained, were com-
pared with regard to the rate of regenera-
tion of the right chela and the rate of
moulting. In one series, AA,, the right
chela was removed at its breaking joint.
In the other series, BB,, both chelae were
removed at their breaking joints and the
last two pairs of walking legs were like-
wise removed. Series 4A, comprised 36
individuals and series BB, 41 individuals.
A comparison of the two series was made
95 days, 130 days and 153 days after the
operation. In each ease the data show
very definitely that the series with the
greater injury molts sooner than the one
with the lesser injury and also regenerates
each of its two chele more rapidly than
the latter regenerates its one removed chela.

The Sequence of Organisms in a Protozoan
Culture and its Irreversibility: Amos W.
Prerers, Zoological Laboratory, Univer-
sity of Illinois.
852
A definite procedure is followed in the
setting and eare of protozoan cultures with
a medium of hay infusion. The seed here
used came from previous laboratory eul-
tures or from field collections. The physio-
logical conditions are determined at almost
daily intervals by physical and chemical
methods. Evidence so obtained points to
fermentative action as the beginning of
metabolism in the culture. The curve for
acidity is of much physiological signifi-
eance. An approximate method of estima-
tion is used to compare the relative abun-
dance of the different organisms and the
results are represented by curves. Rela-
tive curves have been approximately deter-
mined for bacteria, Colpidium, Parame-
cium, Amaba, some Hypotricha, Arcella,
some Rotifera and Stentor. All efforts to
change well-defined curves to decidedly
different relative positions in the history
of the culture have failed. The maxima
of the curves can not be interchanged by
teseeding.
tised (except for experiment) the cysts or
spores of all the organisms found must have
been continually present. Mutual antag-
onism of the different forms is not a prob-
able explanation. The serial succession of
the organisms and the parallel physico-
chemical changes in the environment point
to specific adjustment as a probable hy-
pothesis. The determination of some of
the specific adjustments of Paramacium
and Stentor supports this hypothesis.
An Analysis of Physiological Conditions in
a Protozoan Culture: Amos W. Prrmrs,
Zoological Laboratory, University of
Illinois.
The influence of the physiological states
of protozoa in producing variations from
a supposed standard is seen in the results
of experiments upon both the directional
and the metabolie reactions of this group.
To obviate this important difficulty the

writer proposes to standardize the given
conditions of any culture. Standardiza-
tion of the conditions, if suecessful, uses the
peculiarities of the physiological states for
a more accurate interpretation of the re-
sults of experiment, instead of leaving these
states as objectionable factors in an experi-
mental procedure.
The methods to be used must conform to
at least two conditions. First, they must
not require more than a small amount of
culture liquid (5 to 10 ec.) for a test, in
order. that serial observations can be
made upon the same eulture. Second, they
must be sufficiently accurate and sensitive
to yield results that show the successive
small differences which occur in the history
of a single culture. The special methods
here applied are mostly volumetric and
comprise the determination of: (1) Quali-
tative chemical content, (2) free acidity or
alkalinity, (3) dissolved oxygen, (4) bi-
carbonates, (5) alkali earths, (6) electrical
conductivity, (7) oxygen consumed, (8)
sulphated nitrogen, (9) ammoniacal nitro-
gen, (10) individual salts—nitrites, ni-
trates, chlorides, potassium, calcium, ete.
For both convenience and accuracy, a sys-
tem of standardizing all the necessary
volumetric solutions in terms of one orig-
inal standard acid has been devised. By
these methods one series of data has been
taken from various media promiscuously
selected for comparison, and another series
comes from the history of single cultures.
In both series the biological aspect of the
media was known. Comparison of the
physicochemical and the biological data in-
dicates that variations in the former are
an approximate expression for correspond-
ing changes in the physiological states of
the organisms. The methods here selected
are therefore serviceable for the physio-
logical estimation of the protozoan environ-
ment.

The Evolution of Cclor Characters: R. M.
Srrone, University of Chicago.
Color characters are purely relative
means of distinguishing various individuals
or groups of animals, and their significance
varies according to the experience and
knowledge of the observer. In birds, color
characters are all connected by series of
transitional stages which appear perfectly
continuous even after careful analysis, and
the most highly developed characters may
be found in incipient stages not ordinarily
observable. A study of the colors of birds
has led the writer to believe strongly in
an orthogenetice theory of evolution of color
characters by continuous variation in birds.

The Entomological Ecology of the Indian-
corn Plant: S. A. Forses, University of
Illinois.
This paper consists of material in pure
ecology selected from the mass of matter
accumulated in the course of several years’
study of the corn insects from the economic
point of view. It deals with adaptive rela-
tions of the corn insects to their food plant
and to one another; classifies adaptations of
insects to their food as structural, physio-
logical, psychological, local, biographical
and numerical, giving illustrations of each
class; discusses the adjustment by natural
selection of the life histories of insects de-
pendent upon the same plant; analyzes ex-
amples of competition among such in-
sects; refers to the agency of natural selec-
tion in transforming competitions from
the simultaneous to the serial order; and
theorizes the whole subject by reference to
the general principle of a community of
interest between a phytophagous insect and
its food plants.

The Fauna of Mayfield’s Cave: ARTHUR
M. Banta, Indiana University.
Mayfield’s Cave is a small cave near
Bloomington, Ind., which presents typical
cave conditions having a nearly constant
temperature and conditions of light shad-
ing from twilight to absolute darkness.
Eighty-seven species of animals were taken
in this cave as against 68 heretofore known
from all of the Indiana eaves. Of the 87
species but 21 are permanent residents and
only 8 are found in eaves exclusively.
Species including diptera, lepidoptera (2
species), arachnida and the bats hibernate
in the cave in considerable numbers. Each
cave inhabitant sustains a certain definite
relation to the light, some living only in ab-
solute darkness, others in dim twilight, ete.
Aside from conditions of light and temper-
ature, the distribution of eave animals is
influenced by moisture, the presence of
organic matter which serves as food and the
presence of means of concealment. Some
of the highly modified and truly ecavern-
icolous forms are oceasionally found out-
side of caves in springs, about wells, in
drains and in similar situations. Change
of seasons has little influence upon cave
life. Species which are only temporary
residents and some of the less highly
specialized of the permanent residents are
young and local cave forms, while the
highly specialized cave inhabitants such as
the blind fish, blind eray-fish and the blind
earabids are old and widely distributed
eave forms. The nearest relatives of cave
forms are nocturnal or are dark or shade-
loving species, while the food and habits of
cave species are exactly similar to the food
and habits of their near relatives living in
other situations. The habit of hiding un-
der loose stones and other debris persists
in many cave forms where the habit is ap-
parently altogether useless. Cambarus

Guinea-chicken Hybrids: MicHaru F.
Guyer, University of Cincinnati.
These hybrids, five in number, were pro-
duced by crossing a black Langshang cock
with a common guinea hen. When young
the hybrids resembled more young guineas,
although the shanks were feathered, as were
those of the father. Traces of these feath-
ers still (nearly three years later) per-
sist. The hybrids are much larger than
guineas and have louder and even more
discordant voices. They are extremely
wild. The head shows no trace of either
the comb of the chicken or the helmet of
the guinea, but is covered with feathers
clear to the beak. Neither are wattles
nor earlobes present. The beak, in color
and shape, resembles more that of the
guinea. A trace of the guinea’s white face
is discernible in the hybrid in the immedi-
ate region of the eyes. The neck is very
long and snake-like. The feathers are
more or less intermediate in structure be-
tween those of the parent forms. The
tail is erect and never droops like that of
the guinea. The large quill feathers of tail
and wing not infrequently possess vanes
which are black on one side of the rachis
and more like the hybrid general plumage
on the other. The first one to three
primaries are white in all of the hybrids.
Guineas frequently show similar white
primaries. The color of the head and neck
is mainly black, although in two of the
forms, there is a decided sprinkling of
white feathers in this region. The general
ground color of body, wing and tail plum-
age is dark gray in three of the hybrids,
but in the remaining two it verges more
toward a chestnut color. In all, the feath-
ers are crossed by narrow lighter colored
V-shaped bars which gives the plumage, on
[N.S. Von. XXI. No. 544.
the whole, a decidedly barred appearance.
The conspicuous white dot of the guinea’s
plumage seems to be entirely lost. There
is, however, a secondary inconspicuous
barring in many of the features of the
guinea which possibly may be the source
of the bars of the hybrid. The forms have
not proved fertile and the chief interest
in them will center in the chromosomal
structures of the germ cells.

There is much question regarding the ex-
act ancestry of Plymouth Rocks, but un-
doubtedly the American Dominique and
the black Java are the main sources, with
probably also a considerable admixture of
Brahma blood. The brown Leghorn of to-
day appears to be the descendant of an old
breed of fowls introduced from Italy in
1834.
‘The offspring, 400 in number, of brown
Leghorn 4 & Plymouth Rock 2 were every
one black, except for an occasional feather
of reddish hue in some of the cocks. While
in plumage they thus seem to revert to
the ancestral black Java, this is not so true
of shape and weight, which varies in al!
degrees between that of the two parent
types. The white ear lobes of the Leghorn
always persist. Some of the progeny, in-
deed, resemble black Minoreas very closely.
Most of them have the dark slate-colored
shanks that commonly accompany black
fowls, although about 30 per cent. are
yellow shanked. The comb is the most
variable structure, exhibiting 3 or 4 to
7 serrations. Not infrequently double
combs (two single ones side by side) ap-
pear in the cocks. Various crosses among
the members of this generation and between
them and the parent stocks were made, but

the limits of an abstract will not permit
record of these results. On the whole, no
characters observed, appeared to follow the
laws of Mendel with any accuracy. For
example, black x black have invariably
produced black offspring, so far with the
white ear lobes persisting. A black J x
barred plymouth 9, among others, pro-
duced one male offspring which rather
closely resembles a dark Brahma cock.
Pure white Plymouth Rocks which al-
ways produced white offspring when bred
together, never produced white offspring
when crossed either way with brown Leg-
horns, nor did any of the mongrel off-
spring, when interbred. The majority of
the offspring were barred, the remainder
being nondescripts or occasionally black.
Interbreeding this generation resulted in
the production of several fowls which were
of a pure barred Plymouth Rock type ex-
cept for the persistent white ear lobes of
Leghorn origin.
Observations on some Peculiar Habits of
the Mole-crickets: W. J. BAUMGARTNER,
Kansas University.
The female of our northern mole-cricket,
Gryllotalpa borealis, has quite a loud and
distinct chirp. This seems to be used as a
means of recognition in their dark burrows.
This observation is contradictory to the
conclusion of all writers who say only male
orthoptera chirp, or stridulate. The fe-
male of the Porto Rican species Scopter-
iscus didactylus has the same kind of a
stridulating organ (much smaller and
weaker than that of the male) on its elytra,
and so I econelude it also chirps.
Du Four’s gland of ‘excretory secre-
tion,’ which later investigators have con-
nected with the copulatory organs, is by
my observations and experiments shown to
be an effective protective device. A strongly
fetid and very sticky secretion is ejected
with considerable foree from the siphon-

hke genito-anal opening. This must repel
or retard the most ardent pursuer and so
protect the soft abdomen from the rear.
In the act of copulation these insects
assume the relative positions suited to their
tunnel-like homes. They turn posterior
end to posterior end and ventral side to
ventral side, the male lying on his back.
The sperm is transferred in a spermato-
phore. Scopteriscus has a similar pro-
tective gland, but its copulation was not
observed.
The chirping of the female, the protective
anal secretion and the unusual position of
male and female in copulation which dis-
tinguish the mole-crickets from the rest of
the orthoptera are very evidently adapta-
tions to life in underground tunnels. The
presence of the spermatophore accounts for
the annexed glands in the male Gryllotalpa.
The Reflex Theory of Orientation as Ap-
plied to the Phototaxis of Ranalia: S. J.
Houmes, University of Michigan.
A Note on the Position of the Temporary
Pharynz in the Planarian Embryo: W.
C. Curtis, University of Missouri.
Mattiesen in his extensive account of the
embryology of the European Planaria
torva, which has been recently published
in the Zeitschrift fiir Wissenschaftliche
Zoologie (704), suggests that my desecrip-
tion of the orientation of the adult and
embryonic pharyngeal structures in P.
maculata must have been due to the exam-
ination of a single abnormal specimen or. to
distortion caused by poor fixation. My ob-
servation has been confirmed by Bardeen
(702) ; and in another American form, P.
simplicissima, Stevens (’04) believes the
same orientation to exist, although in this
ease the early disappearance of the primi-
tive or embryonic pharynx makes the mat-
ter difficult to establish. Mattiesen finds
that in P. torva the adult pharynx appears
856 SCIENCE.
just behind the degenerating embryonic
pharynx, which is, therefore, located on
the future ventral part of the body as the
spherical embryo becomes flattened. This
confirms Ijima’s (’84) deseription of the
orientation in Dendrocalum lacteum. In
B. maculata the point at which the degen-
erating embryonic pharynx is last seen is
on the dorso-posterior surface.
The Arrangement of the Mesenteries in the
Cerianthide. J. PuAyFAIR McMurricuH,
University of Michigan.
In 1892 Faurot observed that the mesen-
teries of Cerianthus membranaceus were
arranged in groups of four, each quartet
consisting of a longer and a shorter fertile
mesentery alternating with a longer and a
shorter sterile one, and his observation was
subsequently confirmed by van Beneden
for C. Lloydii. Both authors regarded
the quartets as beginning with the fourth
mesentery on each side of the mid-siphon-
oglyphie line. The study of the develop-
ment of the cerianthid mesenteries has
shown, however, that the first four mesen-
teries on either side of the mid-siphon-
oglyphie line constitute a group distinct
from the others and are comparable to the
eight protoenemes of the other groups of
Anthozoa.
Among the ‘Siboga’ actinians is a
species from Amboina, probably C. elon-
gatus Kwietn. In this form there is on
either side of the mid-siphonoglyphic line
the usual short sterile directive mesentery,
then follow two additional sterile mesen-
teries, and then a long fertile mesentery
which extends almost to the aboral pole of
the body. This last is apparently the so-
called continuous mesentery, and the inter-
est of it lies in the fact that it is the fourth
mesentery and not the second, as in all
other species that have been examined.
This departure, which occurs in all the in-
dividuals of the species examined, corrobo-
[N.S. Vou. XXI. No. 544.
rates the view based on the developmental
history that the four mesenteries on either
side of the mid-siphonoglyphie line consti-
tute a group apart from the rest, and that
the quartets should be regarded as begin-
ning with the fifth mesenteries.
An Improved Form of Reconstruction Ap-
paratus: THomas G. Les, Laboratory
of Histology and Embryology, University
of Minnesota.
Doctor Lee presented a very satisfactory
form of reconstruction apparatus, which he
had designed and which is an improvement
over the models now in use. It consists of
a cast-iron bed plate 84 cm. (34 inches)
thick at sides, and 44 em. (2 inches) thick in
the middle. The top measures 23 x 30 em.
(9x12 inches), and has been accurately
planed and polished, giving an area of 690
sq. em. (108 sq. in.). The side pieces, by
which the thickness of the wax plate is de-
termined, are moved up an inclined plane
which is rigidly fastened to the bed plate in
a manner similar to the movement of the
object holder in a Thoma microtome.
All parts of the top of each side piece
are thus always in the same plane. The
side piece is moved up and down by a
large and accurately made screw at the
rear of the apparatus... After adjust-
ment the side pieces can be firmly fixed
in place by two set screws by means of
a small wrench. A metal seale is placed
on each side piece, so that any thickness of
wax plate can be made from $ mm. up to 1
em. at $ mm. intervals. Thus plates of 3,
1, 14, 2, 24 mm., ete., can be made. Pro-
jecting from the bed block are two metal
strips with a depression to hold the roller
when not in use. This whole apparatus
weighs about 67 pounds, and is quite rigid.
The roller is of polished steel 30 em. (12
inches) long by 6 em. (24 inches) diameter,
with a steel rod projecting at each end and
covered by a movable wooden handle. This

roller weighs 17 pounds, but works very
easily, indeed.
The heating apparatus consists of a metal
frame supporting a copper jacket which
has a coneavity on its upper surface just a
little larger in diameter than that of the
roller. This protects the surface of the
roller from contact with either the metal
or flame. This coneavity could easily be
changed into a hot water bath for the roller,
if so desired. The lamp is a horizontal
Bunsen burner tube with numerous small
openings. _ The roller does not require to
be heated between each pair of plates, and
thus when not in use it is readily rolled up
into the support in front of the bed plate.
This whole apparatus is very solid, com-
pact, accurate and easy to adjust.
Some Abnormalities of Growth Produced
by Parasites on Alcyonaria: C. C. Nut-
TING, State University of Iowa.
In their ‘Report on the Aleyonaria of
the Challenger Expedition,’ Wright and
Studer described a new genus, Calypter-
mus, giving as a generic character a certain
tunnel-lke structure formed by excessively
enlarged spicules, the tunnel being along
one side of the stem or branch. Later
Studer, in reporting on the Aleyonaria se-
eured by the Prince of Monaco’s yacht, de-
clares that this peculiar structure is due to
the presence of an annelid, and is patho-
logical in fact. A similar structure was
found by the writer in a species of Tenella
secured by the Albatross from Hawaiian
waters. The tunnel-like structures, with
the annelids inside, were shown by means
of lantern slides.
In a new species of Dasygorgia from the
same collection the writer found certain
very greatly enlarged polyps which at first
looked like a form of dimorphism hitherto
unknown. Upon dissection, however, these
monstrous polyps were found to contain,
without exception, minute crustaceans,

either embryos or some form of degraded
parasite. These were also shown by means
of lantern slides from photographs made
by the author. It appears that we have
here a condition of affairs in an animal
organism which bears a close analogy to the
production of ‘galls’ in vegetable tissues.
The Origin of the Subclavian Artery in the
Chick: Wm. A. Locy, Northwestern Uni-
versity. (Based on the work of Mr.
Sabin. )
The subelavian artery in birds lies ven-
tral to the vagus nerve and vena cava; in
mammals it occupies a dorsal position with
reference to those structures. On this ac-
count the subclavian arteries do not appear
to be homologous as to origin in these two
classes of vertebrates. ° Hochstetter was the
first in 1890 to clear the question by show-
ing that the definitive subclavian in birds
is of secondary origin. Prior to its appear-
ance there is a vessel arising from the
dorsal aorta, opposite the 15th mesodermic
somite, which supplies blood to the wing-
bud from the third to the sixth day of
development. On the sixth day the sec-
ondary subclavian arises from the ventral
end of the third aortic arch. This new
vessel passes backward and joins with the
primary subclavian artery, coming from
the dorsal aorta, and, from the sixth to the
close of the seventh day of development,
the wing bud receives blood from the two
sources. The primary subclavian then dis-
appears and the secondary subclavian re-
mains as the permanent one.
Mr. C. G. Sabin, a graduate student in
Northwestern University, has traced with
great care the embryonic history of the
subelavians in the bird and has illustrated
the same. His results agree closely with
those of Hochstetter, except that he finds
the primary subclavian in earlier stages
than Hochstetter, and observes that in the
early condition the subclavian arises inde-
858 SCIENCE.
pendently of the segmental arteries, with
which, however, they join later. The illus-
trations which Mr. Sabin gives of the actual
condition of the developing subclavian ar-
teries were very much to be desired, since
Hochstetter’s paper was illustrated only
by a few simple diagrams. The results are
now published in the Anatomischer An-
zeiger, Vol. 26, Nos. 11 and 12, with 29
illustrations.

SCIENTIFIC JOURNALS AND ARTICLES.
Tue April-May number of The Journal of
Geology contains an article on ‘The Zuni
Salt Lake’ of western New Mexico, by Mr. N.
H. Darton. It is illustrated by two maps and
three half-tones. Mr. Douglass W. Johnson
reviews ‘ The Tertiary History of the Tennes-
see River’ and concludes that it has followed
its present course through Walden Ridge for
a long time, ‘ probably since the close of the
Oretaceous period at least.’ This article is
illustrated by nine figures. Professor B.
Shimek contributes an ‘ Additional Note on
Helicina occulata, a recent species, which
also occurs as a fossil in the loess, and con-
cludes that it supports the view that ‘ during
the deposition of the fossiliferous loess the
climate was not glacial. Mr. Rollin T.
Chamberlin describes ‘The Glacial Features
of the St. Croix Dalles Region,’ which is il-
lustrated by three sketch maps. Professor
Stuart Weller describes ‘A Fossil Starfish
[N.S. Von. XXI. No. 544.
from the Cretaceous of Wyoming,’ which he
names Pentagonaster browni. Mr. O. W.
Willcox contributes an article on ‘The So-
called Alkali Spots of the Younger Drift-
sheets,’ which are patches of white efflores-
cence which ‘consist of small amounts of
sodium chloride and much larger amounts of
the carbonates and sulphates of magnesium
and calcium.’ Mr. George C. Matson has a
paper on the ‘ Peridotite Dikes near Ithaca,
N. Y., in which he describes several new
dikes in addition to those noted over sixty
years ago by Vanuxem and much more re-
cently by Professor Kemp, and Mr. Wallace
W. Atwood describes the ‘ Glaciation of San
Francisco Mountain, Arizona.’ This article
is illustrated by a sketch map of the top of
the mountain and it is stated that these rec-
ords ‘may possibly be those of the southern-
most ice which existed in this country during
the Pleistocene period.’
To the American Geologist for April Pro-
fessor Eugene A. Smith contributes a ‘ Bio-
graphical Sketch of Henry McCalley’ with
portrait. Professor Warren Upham has an
article on ‘The Nebular and Planetesimal
Theories of the Earth’s Origin,’ in which he
quotes at length from Dr. T. C. Chamberlin’s
recent paper on the planetesimal hypothesis.
Professor Upham also quotes from Dr. G. K.
Gilbert’s paper on ‘The Moon’s Face’ and
concludes that his explanation of the origin
of the very abundant small and large crateri-
form features of the moon seems largely iden-
tical with Chamberlin’s hypothesis ‘so far as
that hypothesis deals with the segregation of
the originally nebulous matter to form planets
and satellites.’ Professor J. W. Spencer re-
views ‘Dr. Nansen’s Bathymetrical Features
of the North Polar Sea, with a Discussion of
the Continental Shelves and the Previous
Oscillations of the Shore Line.’ Mr. Spencer
says that while this memoir ‘treats of the
physiographic features of the Polar basin, yet
the greater part is devoted to the investigation
of continental shelves, not merely of the
Arctic basin, but also those of the Atlantie,
in which respect it is the most important
work that has appeared anywhere. ‘ Professor

ARTERIOSCLEROSIS in its relation to diseases
of the nervous system is the subject of the
opening paper in the May issue of the Journal
of Nervous and Mental Disease. Dr. EK. D.
Fisher discusses the clinical aspect, and Dr.
Harlow Brooks summarizes the pathology,
with reports of three illustrative cases, one of
syphilis of the cerebro-spinal axis, one of
arteriosclerosis of the brain and spinal cord
oceurring in alcoholism, and one of acute
arteritis occurring in vessels of the central
nervous system in rabies. Drs. W. G. Spiller
and C. H. Frazier follow with the presentation
of some original views on the subject of nerve
anastomoses. They have experimented in this
line in the treatment of cerebral palsies, and
their suggestions open up a field in neurolog-
ical surgery that seems to be full of promise.
Dr. Spiller also contributes a short illustrated
paper, being mainly the report of a case which
came under his observation and seemed to
offer valid evidence for the location of the
fibers of temperature and pain within the
tracts of Gower. Dr. Jas. W. Wherry writes

on the curability of epilepsy, and takes an
optimistic view of the question, conditioned
on beginning treatment promptly upon the ap-
pearance of the disease. His idea of the re-
quirements in such treatment consists of ‘A
study of each case individually; special adapta-
tion of drugs to individual conditions; per-
sonal supervision and individualization of diet,
absolute change of environment.’ The pro-
ceedings of the New York Neurological
Society for December 6, 1904, and of the

THE ONONDAGA ACADEMY OF SCIENCE.
Tne regular meeting of the academy was
held in Syracuse, on the evening of April 15.
Professor W. M. Davis, of Harvard University,
gave an illustrated lecture on the Colorado
Canyon, based upon four visits to the Arizona
plateaus. He emphasized the origin of the
canyon as a valley of normal erosion excep-
tional only in depth, as shown fifty years ago
by Newberry; its independence of the great
fractures of the region whose course is us-
ually north and south, as shown thirty years
ago by Powell and Dutton, while the canyon
is cut from east to west; and the record of a

long geological history magnificently displayed
in the canyon walls. This history of the
region was traced backwards, first stripping
off the horizontal layers of the plateau series,
next reconstructing, untilting and stripping
off the now inclined layers of the so-called
Algonkian ‘ wedge’ and then roughly building
the lost mountains of the erystalline founda-
tion rocks, commonly regarded as Archean but
not yet demonstrated to be of so great an-
tiquity. Having thus traveled backwards
through the ‘ corridors of time’ to the earliest
stage of geological history there recorded, the
return journey was made along the normal
succession of events. Six long ages of time,
occupied alternately by deposition and by
erosion, were thus reviewed: Three ages of
enormous deposition, requiring a correspond-
ingly enormous erosion elsewhere, and three
alternate ages of enormous erosion, suggesting
an equally enormous deposition elsewhere.
The short chapter of canyon erosion was en-
tered upon only after the long earlier ages were
closed: thus a correction was suggested for the
erroneous view that the erosion of a great
canyon requires a long part of geological time.
The apex of the Algonkian wedge and the
associated ancient plains or peneplains of
erosion, best seen from Grand View, sixteen
miles east of the railroad terminus, were indi-
cated as the points on which the attention of
the inquiring visitor should be focussed. The
voleanic history of the district, as associated
with the erosion of the canyon, was briefly
touched upon. J. EK. Kirxwoop,

immigrants in New York from various coun-
tries of eastern Europe show that the Jewish
type in those countries is not Semitic, but
varies in the different countries, always ap-
proximating, in stature and cephalic index,
to the native or Christian population of the
respective countries.
‘Anthropometric Work at the St. Louis
Exposition, R. S. Woodworth and F. G.
Bruner. As many as possible of the racial
groups represented at the exposition were
measured. The best material was found
among the Philippine Islanders, of whom
about 700 were measured. The Christianized
tribes, such as the Tagalog, Pampango, Ilo-
eano, Bicol, Visaya, were found very uniform
in physical type. Measurements showed no
clear evidence of differentiation among them.
The average height of the several tribes dif-
fered but little from 161 ecm., the cephalic
index differs little from 83, ete. The Moros
of Mindanao also are practically identical in
physical type with the Christian tribes. The
pagan Igorots and Bagobos seem to differ con-
siderably from this type, especially in height,
which is about 155 cm.; while the Negritos
were clearly marked off from all the rest by
their kinky hair, small stature (144 cm.),
broad nose, and small head in proportion to
stature. R. S. Woopwortu,

THE PHILOSOPHICAL SOCIETY OF WASHINGTON.
Tuer 600th regular meeting, held April 15,
1905, was celebrated by historical addresses in
University Hall of the George Washington
University, followed by a social hour with
refreshments. ,
After a brief address by President Little-
hales, half a dozen papers were read giving a
review of the activities of the society since its
foundation in 1871, under the presidency of
Joseph Henry, in the lines of most interest to
its present membership. Mr. Gore grouped
and characterized succinctly the papers pre-
sented in mathematics. Mr. Wead reviewed
the papers on physics, beginning with Henry’s
“Aberrations of Fog Signals’ and including
recent notable work on aerodynamics. Mr.
Clarke told of the great local development of

activity in chemistry since 1871. Mr. Gil-
bert spoke of the opportunities the society had
furnished to discuss questions in geology, in-
stancing cases where the discussions had led
to important researches. ‘Mr. Hayford re-
called some of the notable advances in geodesy
that had been presented to the society, Mr.
Eichelberger reported on the papers in astron-
omy and Mr. Bauer spoke of the activity in
electricity and magnetism. A brief letter
from Dr. Gill was read regarding the interest
in biology before the formation of the other
scientific societies.
THE 601st meeting was held April 29, 1905.
Professor W. S. Eichelberger exhibited one
of the Riefler self-winding astronomical clocks
belonging to the Naval Observatory and de-
seribed its construction. It is in a case from
which about one eighth of the air is ex-
hausted; the pendulum is of nickel-steel alloy
compensated ; the power comes from two small
cells of battery and is applied about twice a
minute. The rate is very small and very
constant.
Professor F. H. Bigelow then spoke on
‘Tonization and Temperature-Effects in the
Atmosphere.” The great problems in meteor-
ology relate to the vertical distribution and
semidiurnal curve of temperatures; and to
the variations in vapor tension, atmospheric
electricity and magnetic field. A great num-
ber of curves representing the results of ob-
servations on the quantities involved in these
problems were exhibited, and the attempt was
made to explain the facts according to the
modern theory of ionization. The paper will
appear in the Monthly Weather Review.

DISCUSSION AND CORRESPONDENCE.
CONNECTION BY PRECISE LEVELING BETWEEN THE
ATLANTIC AND PACIFIC OCEANS.
To THE Eprror oF ScieENcCE: In your issue
of April 28, 1905, page 673, is an article by
Mr. Hayford on ‘Connection by Precise Level-
ing between the Atlantic and Pacific Oceans.’
About twenty years ago I wrote to ScIENCE in
connection with precise leveling over the Alle-
ghanies and the Rocky Mountains, and stated
that it might be well to have a systematic
determination of bench marks at stated in-
tervals owing to the unrest in the earth’s crust.
At that time I stated that my work on the
corps of the Pennsylvania Railroad had shown
me that, however carefully the bench marks
might be established at any one time, at the
expiration of a comparatively few years there
would be a discrepancy between them and the
datum plane. The Pennsylvania Railroad has
reviewed its bench marks a number of times
owing to these discrepancies due to earth mo- *
tion.
tween the levels of the Atlantic and Pacific
Oceans, unless the bench marks were estab-
lished by surveys which began and ended at
exactly the same period throughout the entire
distance, might be due to earth movements
between the times of the beginning and the
end of the survey.
I would again suggest, as I did at my first
letter to this paper, that the United States
Geological Survey secure not only the lists of
bench marks of all railroads, but the varia-
tions that have occurred in these bench marks
as shown by repeated surveys. If these are
carefully tabulated throughout a century, we
may obtain important information in regard
to the upward and downward crustal move-
ments across the continent.

THE HORIZONTAL PLANE OF THE SKULL AND THE
GENERAL PROBLEM OF THE COMPARISON OF
VARIABLE FORMS.
In comparative studies of the skull it is
customary to select one transversal plane de-
fined by the axis of symmetry with which it
is at right angles and by two points, as the
standard plane to which the skull is referred.
Some authors have made the selection of the
two determining points based on morpholog-
ical considerations, while others have en-
deavored to determine the physiological hori-
zontal position, determining the latter by two
points which are more or less accurately par-
allel to the direction of horizontal sight.
When this problem is considered from a
purely morphological point of view, it will be
recognized that there is no justification in
selecting arbitrarily two points and disregard-
ing all others, but that the best method of
comparison must be based on the assumption
that every point of the skull has equal weight
and that the nearest approach of all points
must be attempted. In this form the problem
is applicable to the comparison of all variable
forms.
The most favorable superposition of any
two forms will be obtained when the sum of
The want of agreement, therefore, bewe “the squares of the distances between all pairs
of homologous points becomes a minimum.
We will refer the body to a system of rect-
angular coordinates and eall zw’, y’ and z’ the
ordinates of a point of the first body, x”, y”
and 2” the ordinates of the homologous point
of the second body. By moving the second
body by the amounts wu, v and w in the direc-
tion of the three ordinates, we can modify the
relative positions of homologous points with-
out torsion of the body. Then the sum of the
squares of the distances of homologous points
S(a/ — a//— u)?+ S(y/—y’ — 0)e + >(2’—2” —w)?
is to be a minimum. Therefore,
>(a/ — a’ —u) =0.
And

Since we may assume the origin of the first
system of ordinates arbitrarily, we may take
32! = Sy’ = 32’ = 0;
in other words, we take the geometrical center
of gravity of the first body as the origin of
our system of ordinates. Then
Sa’ = Sy” = Se’ =0;
i. e., the two bodies must be so placed that
their geometrical centers of gravity coincide.
Provided the two forms are symmetrical,
this result gives a complete solution of the
problem. If the forms are irregular, the de-
gree of torsion must be determined which will
give the best result. In most cases the form
in question will be symmetrical in at least
one direction, so that torsion in one direction
only need be considered. Starting with the
geometrical center of gravity as the origin of
a system of polar coordinates, we have for
any given pair of points the coordinates I’
and 1” as distances from the center, and a/
and q@” as angles with the zero line. If we
_ give the second system of points the torsion
&, we find that
>i? + V72— oI’ cos (é + a/’ —a’)}
must be a minimum; or
SVV’ sin (£ + a// —a’/) =0,
SVU’ sin (a// —a’)
SV’ cos (a// = a) §
=
Theoretically, the problem can, therefore, be
solved. By using a limited number of well-
selected points a good superposition of the
two forms can be made.
Experiments, so far as carried out, indicate
that alveolar point, nasion, bregma, lambda,
basion and pterion give a good superposition
of skulls.
It will be noticed that if this method is pur-
sued the arbitrary element in composite draw-
ings or photographs may be eliminated.

XUALA AND GUAXULE.
Tue location of two Indian villages, Xuala
and Guaxule, mentioned in some form by all
of the chronicles of Hernando de Soto’s wild
and unfortunate expedition (1539-41) through
SCIENCE.
863
the territory now included in the southern
states, are important in determining the route
of this Spanish adventurer. If the location
of these two villages—especially the first—
can be determined with reasonable certainty
it will enable us to fix the route of the Ade-
lantado with comparative accuracy from his
landing place at Tampa Bay, Florida, until
he reached the vicinity of Mauvilla in Ala-
bama.
The widest variation in opinion of the nu-
merous authorities touching upon the subject,
relates to the position of Xuala; these views,
however, may be classed in two unequal
groups, as is evident from the following list:
The map of Cornelius Wytfliet in his ‘ De-
serip. Ptolemaica (1596)’ locates this village
on the west side of Savannah River near the
head. DeLisle’s map (1707?) in French’s
‘Hist. Coll. La.,’ though indefinite, places it
west of the Savannah. Later authorities lo-
eate it as follows: Pickett (‘ Hist. Alabama,’
I., p. 8); C. C. Jones, Jr. (‘Hernando de
Soto, p. 18); Cyrus Thomas (5th ‘ Ann. Rep.
Bur. Eth., p. 95); and Theodora Irving (‘ Hist.
Cong. Florida,’ IT., p. 8), all locate it west of
the upper Savannah in Nacooche valley, Ha-
bersham County, Georgia, or in that imme-
diate vicinity. Mr. James Mooney (19th
“Ann. Rep. Bur. Eth., pt. 1, p. 195) and Wood-
bury Lowery (‘ Spanish Settlements within the
United States,’ p. 230, in the text, but not on
the map) locate it in the ‘piedmont’ region of
North Carolina, about the head of Broad
river—which would be about Henderson
County. Gilmore Shea in his article entitled
‘Ancient Florida,’ in Justin Winsor’s ‘ Narra-
tive and Critical History of America, II.,’
follows, in this part of De Soto’s route, the
course given by C. C. Jones, Jr. Bucking-
ham Smith on the map in his ‘ Narrative of
De Soto’ (Bradford Club Series, V., pl. 5)
places Xuala about Habersham County,
Georgia, but locates Guaxule to the north-
west, apparently about Towns County of the
same state, or possibly over the line, in Ten-
nessee. Although Shipp (‘De Soto and
Florida’) does not locate Xuala, he places
Guaxule in Bartow County, Georgia, thus
agreeing substantially with Pickett, Jones and
864
Thomas. The ‘New International Encyclo-
pedia’ follows, in part, Mooney and Lowery,
but also differs from them in part.
It will be seen from this list that the gen-
eral consensus of authorities—all, in fact, but
two or three—locate Xuala somewhere in
northern Georgia, most of them in Habersham
County, while Mooney and Lowery place it in
southwestern North Carolina, somewhere in the
region of Henderson or Rutherford County.
Although the article ‘De Soto,’ in the ‘New
International Encyclopedia’ apparently fol-
lows Mooney in locating Xuala, though it does
not mention the name, it differs radically from
them in regard to the immediately following
portion of the route, carrying it down the
Coosa, instead of the Chattahoochee. It is
rather strange that Lowery on the ‘Sketch
Map’ of his work locates Xuala in or near
Habersham County, northeastern Georgia, and
Guaxule about Bartow County, and follows
down the Coosa River instead of the Chatta-
hoochee as in his text (p. 230).
The object at present is to examine briefly
the data and determine, if possible, which of
these two divergent views agrees most nearly
with the original chronicles of the expedition,
and the topography of the country, or whether
both are erroneous.
All the facts bearing upon this particular
inquiry to be drawn from the original chron-
icles relate to the march from Cofitachiqui—
where the Adelantado was so royally enter-
tained by the noted cacica—to Chiaha, where
he paused to recuperate because of abundant
food and pasture.
It is now generally conceded that Cofitachi-
qui was located on the east bank of Savannah
River, at or near Silver Bluff, about twenty-
five miles below Augusta, though one or two
authors have contended that it was at the
junction of Broad and Savannah Rivers. We
shall, therefore, proceed upon the assumption
that it was at or in the vicinity of Silver Bluff
—as this theory is maintained by the views
we propose to discuss; calling attention first
to that theory which places Kuala in western
North Carolina.
From Cofitachiqui, according to all the
original chronicles, De Soto and his army pro-

[N.S. Vou. XXI. No. 544.
ceeded northward, without, so far as the rec-
ords show, recrossing the river, hence on the
east side of the Savannah, in what is now
South Carolina. However, in order to pro-
cure a supply of food the army was divided
into two parties, that with De Soto going
directly onward, while the other turned aside,
some twelve leagues, say the chronicles (prob-
ably toward the bottom land), where there was
a store of maize offered them by the cacica.
Before reaching Xuala they passed through
some small yillages or settlements of the
Chalaque (or Achalaque) now recognized as
the Cherokees. The time given for the march
from Cofitachiqui to the Chalaque by the dif-
ferent chroniclers differs considerably; Elvas
states it was seven.days; Garcilasso, eight;
and Ranjel (in Oviedo), only two. Biedma
does not mention Chalaque, but makes the
time occupied in going from Cofitachiqui to
Xuala eight days. As further data regarding
the time occupied, it may be stated that Elvas
makes the time from Cofitachiqui to Xuala
twelve days. Ranjel makes it seven days,
mentioning as an intermediate village Gua-
- quili—not noted by the others—which he says
was three days’ march from Xuala. Garcil-
asso makes the distance between the same
points fifty leagues. All agree in giving the
time from Xuala to Guaxule as five days.
As the particular view we are now discuss-
ing is that maintained by Mr. Mooney and
Mr. Lowery (in his text) and the latter fol-
lows the former without going into details,
for these we have necessarily to refer to the
statements by the former.
According to these the Chalaque villages
were probably on or near Keowee River, for
which point we may assume Anderson, An-
derson County, South Carolina, as among the
modern names along the supposed route.
From this point the Adelantado’s force pro-
ceeded to Xuala, which this authority, as al-
ready stated, places about Henderson County,
North Carolina. From there, according to
both authorities, they moved west, ‘down
French Broad’ River as far, we are justified
in supposing (as no point is mentioned), as
to or near the site of Asheville. From there
these authors carry them southwest to

White County, Georgia, where they arrive at
Guaxule.
as this theory supposes, was according to the
geologist of the U. S. Geological Survey, who
has been at work in that section, most likely,
as follows: Using modern names to designate
the points; from Anderson, South Carolina, to
Greenville, same state, 26 miles; thence across
Blue Ridge to Hendersonville, North Caro-
lina, 85 miles; thence down French Broad
valley to Asheville, 22 miles; thence through
Hominy Gap and up Richland Creek to
Waynesville, 30 miles; thence through Balsam
Gap and down Scott’s Creek to Webster, 24
miles; thence across Tuckasugee River and
Cowee Mountains to Franklin, 17 miles;
thence across Nantahala River and down
Shooting Creek to Hiwassee, 32 miles; thence
up Hiwassee River and down the Chatta-
hoochee to Nacoochee, White County, Georgia,
25 miles, part of this line being along an old
Indian trail. As the distance from Silver
Bluff to Anderson is about one hundred miles,
two or three more or less, this makes the entire
distance along this supposed route from Co-
fitachiqui to Guaxule three hundred and eleven
miles, and from Cofitachiqui to Xuala, one
hundred and sixty-one miles, and from Xuala
to Guaxule one hundred and fifty miles.
Though the route actually traveled accord-
ing to this theory may not have been precisely
that laid down, it must have been near to and
parallel with it, and the distance and character
of the country were substantially the same.
Our reasons for rejecting this theory are as
follows: First, the distance, at least between
some of the points, is too great to have been
traveled by the army with its incumbrances,
among which was a drove of hogs, in the
time specified. These hogs may by constantly
moving have become good travelers, and may
have accomplished the trip from Cofitachiqui
to Xuala, a distance of about one hundred and
sixty miles} in twelve days—the longest time
given by any of the chroniclers. But when
the distance from Xuala to Guaxule, which
on this route was at least one hundred and
fifty miles, has to be traveled in five days, the
time given by all the chronicles—a rate of
thirty miles per day—the requirement becomes
SCIENCE.
This route, if traveled by De Soto ~
865
an utter impossibility for an army thus ham-
pered, and scarcely possible for an army free
from these incumbrances, especially through
a rough and densely wooded country where
there were no other roads than narrow path-
ways.
This route places Xuala on the west or
north of the Blue Ridge which has to be
crossed in going from Greenville to Hender-
sonville.
Another insuperable objection to this route
is that it requires us to assume that the ter-
ritory of the cacica extended into western
North Carolina, or included a detached sec-
tion therein with the Sara or Cheraw, a Siouan
tribe, as subjects, hedged in between the
Cherokees and the Catawbas. This would be
extraordinary.
This assumption is absolutely necessary, if
we follow the theory in question, as it is clear,
from all the chronicles, that Xuala was under
the cacica’s control. It is even stated by one
chronicler that after she made her escape,
which occurred between Xuala and Guaxule,
it was ascertained that she was at the former
village where she and the negro Robles, who
escaped at the same time, were living as hus-
band and wife. The assumption of this route
requires not only the supposition that the
Cheraws were her subjects and their country
in her kingdom, but also when she escaped
she went back northward into western North
Carolina instead of continuing southward to
her own proper capital. It also necessitates
the supposition that her flight was mostly
through Cherokee country, where she would
more likely have been taken captive and pos-
sibly slain than kindly concealed and helped
on her way.
Another reason for rejecting this theory is
that it places Guaxule in White County,
Georgia, where no mound of the character de-
scribed is known to exist or to have existed.
It is claimed by advocates of the theory that
there is a mound which will answer the de-
seription near Clarksville. This, however, is
a mistake. There is, it is true, a mound in
that locality, but it will by no means fill the
requirements. It is in the- upper part of
Nacoochee valley, near its western extremity,
866
and it is only about, or a little over, twenty
feet high, elliptical in form and flat on top.
Its base diameters are 190 and 150 feet and its
top diameters 90 and 60 feet. There are no
evidences of terraces or a graded way; the sides
slope gradually from the summit. It has been
plowed over for many years, but this would
not have effaced entirely a terrace or graded
way had there been one. Moreover, there
were no such indications extant half a century
ago. There is, however, a mound in Bartow
County, Georgia, which does fully meet the
requirements of the chroniclers’ descriptions.
Another reason for rejecting this route is
that it follows down the Chattahoochee River
instead of the Coosa; in other words, elim-
inates the ‘Coza’ for which the Adelantado
was in search, and which his successors en-
deayored to reach. Hamlet is taken out of
the play unless the name ‘ Coza’ is transferred
to Chattahoochee.
Another reason for considering this theory
erroneous is that although the army must
have passed through Cherokee territory after
leaving Xuala, if this route was followed, no
mention whatever of this fact is made by any
of the chronicles.
Finally the theory is erroneous because it
is based on a mistake. It is apparent, from
the statement of the author we have been re-
ferring to, that the conclusion reached by
others, that Xuala was in northeastern
Georgia, was set aside because he had ascer-
tained, as he believed, that there was formerly
a tribe of Indians named Suali or Suala in
western North Carolina; hence as Xuala
might be pronounced Shuala, the two must be
one and the same people, in fact he says (Nine-
teenth Annual Rep. Bureau of Eth., Pt. 195):
“As the province of Chalaque is the country of
the Cherokee, so the province of Xuala is the
country of the Suali or Sara Indians, better
known as the Cheraws.”
On this slender foundation of a slight re-
semblance in names does the theory appear to
be built, which takes De Soto and his army,
with their hogs and other incumbrances, into
the ‘piedmont region of North Carolina.’
The objection, however, does not stop here,
for the statement that there was an Indian
SCIENCE.
[N.S. Von. XXI. No. 544.
tribe in southwestern North Carolina known
as Suali or Suala appears to be based solely on
the name as used by John Lederer in his
‘Discoveries in Three Several Marches’
(1672). But it has been shown (American
Anthropologist, N. S., Vol. 5, No. 4, 1903)
that his reputed expedition into Carolina is
clearly a fiction, that he was never nearer this
point than along the southern border of Vir-
ginia, his statements in regard to this section
are, therefore, unreliable. What few facts he
mentions being obtained, in all probability,
from the Indians along Roanoke River, and
from the accounts of other earlier explorers,
with which he seems to have been familiar.
His name Suali or Suala seems to refer to
De Soto’s Xuala, of which he appears to have
obtained knowledge; in fact, he states that it
was obtained from the Spanish. As he knew
it was somewhere in the direction of his im-
aginary journey without any knowledge as to
distance, he uses the name to give weight to
his fictitious narrative. Distance would have
troubled a writer but little who definitely
placed a great lake in western North Carolina
and believed that the Pacific laved the western
slope of the Alleghanies.
Unfortunately, however, for the theory,
Lederer nowhere applies the name to the In-
dians, but throughout expressly limits it to
mountains, giving the name Sara to the In-
dians. “ The theory, therefore, as given is abso-
lutely without a foundation stone, as the name
Suali or Suala was never applied to Indians
so far as we are able to ascertain until Mr.
Mooney so used it in his ‘Siouan Tribes of
the East.’
Believing the foregoing reasons to be en-
tirely sufficient for rejecting the theory that
Xuala was in the ‘piedmont region of North
Carolina,’ we next proceed to give our reasons
for believing that this village or province was
located in northeastern Georgia, and Guaxule
in northwestern Georgia, most likely in Bar-
tow County.
In attempting to trace that portion of De
Soto’s route now under discussion it is best
to accept what seems to be the most satisfac-
tory evidence in regard to one particular lo-
cality mentioned. One item is given by Gar-
June 2, 1905.]
cilasso in respect to Guaxule that appears to
fix this town, beyond any reasonable doubt, at
the mound group near Cartersville, Bartow
County, Georgia. The statement of this au-
thor is as follows: “ La casa estava en un cerro
alto, como de otras semejantes hemas dicho.
Tenio toda ella el derredor un paseadero que
podian pasearse por el seis hombres juntos.”
“The house [of the chief] stood on a high hill
{mound] similar to others we have already
mentioned. It had round about it a roadway
on which six men might march abreast.”
The ‘similar to others we have already men-
tioned’ is evidently intended to signify it
was artificial, and this is admitted by all who
allude to it. The statement that it was ‘high’
signifies more, in the eyes of the Spaniards,
than an ordinary elevation. The large mound
of the Etowah group near Cartersville, Bar-
tow County, Georgia, is 66 feet high with base
diameters of 380 and 830 feet, and top diam-
eters about 160 and 180 feet. Running up
the south side is a broad roadway varying in
width from 37 to 56 feet. In bulk it is next
in size to the great Cahokia mound near St.
Louis. Here then we have a mound which
will completely satisfy the description, and the
only one in all that section of the south—as
is now positively known—which will do so.
Moreover, it is sufficiently near Canasauga
River to agree with the narrative. There is
no reason, therefore, except to maintain a
theory, why this should not be accepted as the
site of Guaxule. Assuming this as one fixed
point, the possibilities of the position of Xuala
become much more limited than without this
determination.
As the suggestion above mentioned, that the
Chalaque villages were near the Keowee River,
may be accepted as probably correct, it is ap-
parent from the limited time of the march
from Xuala to Guaxule—five days—that we
must place the former town somewhere in
northeastern Georgia, probably in White or
Hall County or in that section.

THE TORREY BOTANICAL CLUB.
A REGULAR meeting was held on April 11,
at the American Museum of Natural History,
President Rusby in the chair and twenty-two
additional members present.
The paper of the evening was on ‘Some
Edible Seaweeds, by Professor H. M. Rich-
After reference to the indirect importance
of plankton organisms as a source of food for
-animal life in the sea the speaker referred to
- those forms of alge which are used directly
by man as foodstuffs. They were grouped
roughly under four heads—blue-green, grass-
green, brown and red alge.
In the first group, specimens of a form
much prized by the Chinese were shown, which
is, according to good authority, Nostoc com-
mune flagelliforme. This becomes highly
gelatinous when soaked in warm water and is
used as a thickening or sauce. A Japanese
form, ‘ Su-zen-ji-nori,’ of more doubtful na-
ture, but probably an Aphanothece, was also
shown.
Among the grass-green forms mention was
made of xarious species of Ulva and Entero-
morpha, which in dried form go under the
mame of ‘laver’ in the British isles and
-€ao-nori’ among the Japanese.
Among the brown forms only one of the
Fucacez was mentioned as an article of food,
namely Durvillea utilis, which is said to be
eaten by the natives in certain parts of Chili.
The Laminaria forms, however, include a
large number of edible species. Alaria escu-
lenta, common both here and in Europe, was
at one time eaten occasionally in the occident.
At the present time the Japanese and Chinese
make great use of these forms, indeed, after
fish, they constitute the chief article of export
of the Hokkaido. They are exceedingly
plentiful in that region and their collection
and preparation for market is a thriving busi-
ness. In this connection the report of Pro-
fessor Miyabe and others was passed around
and attention was called to the illustrations
showing the mode of harvesting the seaweeds.
The two most important species seem to be
Laminaria saccharina (Laminaria japonica)
and Ulopteryx pinnatifida (presumably iden-

tical with Undaria distans more recently sepa-
rated by Miyabe and Okamura), which are
known under the respective names of ‘Kombu’
and ‘ Wakame’ by the Japanese. Many other
forms are eaten, however.
After reference to the well-known examples
‘Trish moss’ (Chondrus crispus) and ‘ dulse,’
it was said that the two types most used are
the delicate Porphyra forms and the more
massive cartilaginous kinds, such as various
Gigartina, Gelidium, Gloiopeltis species. Por-
phyra has also been eaten by Europeans and
is said to be used by the natives in paris of
Alaska, but it is most highly prized by the
Japanese and Chinese. Under the name oi
‘asakusa-nori’ it is put up in neat tin boxes
and largely sold in the Tokio markets, it being
used by itself or for thickening, giving, as it
does, a very glutinous mixture with hot waiter.
‘Fu-nori,’ used chiefly as we use starch, is a
mixture of species of Gloiopeltis and Endo-
trichia, and, like all these forms, is sold dried.
The speaker referred to agar-agar, which,
on Wiesner’s authority, is said to come irom
different species in different regions. That
of Ceylon is from Gracilaria lichenoides, that
of Java from Eucheuma spinosum, while the
Japanese variety is furnished by Gelidium
corneum and cartilagineum and Gloiopeltis
tenax. Agar, in addition to its uses as a
culture medium in bacteriological research, is
said to be employed sometimes as an adulter-
ant in the jellies of commerce, where it may
be recognized by the siliceous frustules of
diatoms, ete., from which it is never free.
Other forms of Floridee are used as food-
stuffs, attention being called to their figures
in a Japanese popular work on the useful
plants of Japan.
In regard to the food value of alg it ap-
pears that many of them, especially the blue-
green forms, contain a very high percentage
of proteids, though not much else of value.
The gelatinifying substances obtained from
the red forms appears to be a substance called
gelose, which is similar to, or identical with,
the pectic substances so commonly found
either deposited in the middle lamella of the
cells of higher plants, or in the walls them-
selves. Mention was incidentally made of the

use of seaweeds in the manufacture of iodine
and soda-ash. Dr. Rusby exhibited specimens
of Fucus vesiculosus and an unnamed form,
which are used medicinally.
Dr. Howe spoke of dulse as an article of
food and of its occurrence in the markets of
New York.
After further discussion, adjournment fol-
lowed.

DISCUSSION AND CORRESPONDENCE,
MARINE ZOOLOGY IN THE HAWAIIAN ISLANDS.
To THE Eprror or Science: At a time when
zoologists are making their plans for summer
vacation work it seems opportune to direct
attention to the advantages offered even in
such a distant territory as the Hawaiian
Islands. During a visit to the islands last
year, under the auspices of the Carnegie Insti-
tution, for the purpose of studying the living
corals, I was afforded the privileges of the
public aquarium recently established near
Honolulu, and the directors of the institution
desire it to be known that they will be pre-
pared to accord a similar courtesy to other
zoologists visiting the islands for purposes of
research.
The aquarium is a modest structure, erected
a little over a year ago, and is under the con-
trol of the Rapid Transit Company, though
the funds were largely provided by the gen-
erosity of different gentlemen interested in
the welfare of the islands. It is most ad-
vantageously situated at Waikiki Beach, a
suburb of Honolulu, and the adjacent coral.
flats constitute most favorable collecting
ground. Though no special appliances beyond
exhibition and experimental tanks are avyail-
able, yet the advantages of these and a con-
stant supply of sea-water appeal to any stu-
dent desirous of carrying out investigations
on living forms. Moreover, with a generosity
which is very praiseworthy, the directors are
prepared to make whatever reasonable adapta-
tions may be required.
Our knowledge of the marine fauna of the
Hawaiian Islands is becoming rapidly extend- .
ed, mainly through the reports on the collec-
tions made by the U. S. Fishery Bureau,
under the direction of President D. S. Jordan,
during the two successive seasons, 1901 and
1902. The large addition to the number of
species of fishes alone shows how very de-
sirable was such faunistic work, and other
groups are yielding a corresponding number
of new forms. The physical conditions of
the coral reefs have been studied in part by
Professor A. Agassiz. Though the luxuriance
of the life on the reefs does not equal that in
\

the more distant Tahiti, Samoa, or the Philip-
pine Islands, yet there is sufficient, particu-
larly in such places as Kaneohe Bay, to satisfy
the most ardent investigator.
For the student of terrestrial forms the
islands are particularly interesting on account
of the influence of introduced animals and
plants upon an indigenous fauna and flora.
Representatives from the east and from the
west, from temperate and from tropical re-
gions, here flourish, and against the pests a
strong corps of entomologists is engaged in
further introduction of possible remedial
forms. The fact that the land shells of the
islands served to supply the Rev. J. T. Gulick
with material for the theory of isolation adds
an interest to the evolutionary biologist. The
ethnology and various departments of natural
history are well cared for by Professor T. H.
Brigham, of the Bishop Museum, and his staff
of assistants.
As a last word of attraction regarding the
situation of the aquarium one may quote from
the ‘ Report on Collections of Fishes made in
the Hawaiian Islands’ by Professor O. P.
Jenkins:
Of all situations about the island of Oahu, the
submerged reef which extends from the entrance
of the harbor of Honolulu to some distance past
Waikiki furnishes the most prolific supply of
fishes, both as to number of species and amount
of the catch. This reef at low water is from a
few inches to a few feet under water and ex-
tends from one mile to two or three miles from
the shore, where the water abruptly reaches great
depths. Over the surface and along the bluff of
this reef may be found representatives-of most of
the shore fauna of the Hawaiian Islands. This
reef, so favorably situated, so accessible, and so
rich in material, can not fail to be of increasing
interest to naturalists who may have the good
fortune to devote themselves to the study of its
wonderful life.

Fayant and E. O. Hovey has finished its first
exploration of the northern part of the Western
Sierra Madre Mountains of Mexico. A sum-
mary account of the first half of the trip, from
El Paso to Guaynopita, has been given to the
readers of Science. The second half of the
journey was no less interesting than the first
and was fully as productive of scientific ob-
servations.
Leaving Guaynopita by pack train on March
11, the first stage of the journey was the climb
of 3,500 feet out of the Yaqui (Aros) canon
in which Guaynopita is located on to the great
mesa out of which the mountains of the region
have for the greater part been carved. The
contrast in vegetation between different parts
of this section may be illustrated by the state-
ment that fan-leaf palms flourish in the gorges
near the river, while on the high mesa one
finds the great long-leaf sugar pine predom-
inant.
Our course lay southward for sixty or
seventy miles along the broad plains and nar-
row divides forming the mesa, or connecting
different parts of it, and we had abundant
opportunity of studying the topography of the
great Tutuaca Cafion, which is tributary to
the Yaqui (Aros), and of observing the contest
for the drainage of the plateau between the
streams flowing to the west and those flowing
to the east. The dissection of the plateau
is more pronounced toward the west, and our
cross-section of the cafion of the Tutuaca
River from its eastern boundary at the edge
of the Mesa Venado disclosed acid and basic
lavas, tuffs, agglomerates and conglomerates
through six thousand feet of beds. The west-
ern rim of the Tutuaca Cafion is near the
important Dolores mineral district. Some of
the extensive igneous action has been accom-
panied and followed by strong mineralization
of veins. At Dolores a fifteen-stamp mill of
the most up-to-date construction is just being
completed under the supervision of Manager
J. Gordon Hardy for the treatment of the
rich gold and silver ores of the Alma Maria
vein by the direct cyanide process.
Near Dolores we turned southward again
and pursued our course along a series ot high

mesas, divides, arroyos and river channels un-
til we reached the little Indian town of
Yepachic. In this part of our route we passed
through three or four fertile ranches and at
Yepachie found the people (Tarahumares and
Pimas) living for the most part from the
tillage of a small alluvial plain surrounded by
low mountains. Here we turned westward
again and within a few miles reached the
Cerro Boludo (Bald Mountain) district, which,
like several others on our route, is character-
ized by a mineralized quartz vein twenty to
eighty feet wide which can be seen traversing
hill and vale for miles.
Six or eight miles south of Cerro Boludo
lies the little Mexican camp of San Francisco,
where a diminutive two-stamp mill feeds a
primitive arrastra as a preliminary to pan
amalgamation of the gold. Thence the
Ocampo trail leads over a divide and across
the deep cafion of the Rio de Mayo, down into
and out of the Rosario arroyo before the great
arroyo is reached in the bottom of which, at
the Junction of two branch arroyos, is crowded
the mining camp of Ocampo—a place better
known by its old name of Jesus Maria. This
is the site of many rich gold and silver mines,
the most famous of which is the Santa
Juliana.
From Ocampo to Mifiaca, 100 miles, the trail
crosses the high mesa, which has a gentle slope
eastward and is partly dissected by compara-
tively shallow cafions of varying depths.
Mifiaca, the present terminus of the Chihua-
hua and Pacific Railway, is in a beautiful
broad basin about 7,000 feet above tide, which
is traversed by the headwaters of the Rio
Verde, a tributary of the Yaqui (Aros) River.
At Mifiaca our party took train for Chihua-
hua and thence went by rail to El Paso, com-
pleting our noteworthy circuit in the western
Sierra Madre Mountains of northwestern
Mexico. The circuit was not very long, com-
pared with the mileage of some expeditions,
but the results along lines of physiographie,
dynamic and economic geology are of impor-
tance and will be published as soon as they
can be put into proper shape, while the photo-

A BIOGRAPHICAL DIRECTORY OF AMERICAN MEN
OF SCIENCE.
THE undersigned is compiling a ‘ Biograph-
ical Directory of American Men of Science.’
It was begun as a manuscript reference list
for the Carnegie Institution of Washington,
but arrangements have now been made for its
publication. The book should be ready in the
autumn, nearly 4,000 biographical sketches
being in type. The proofs have been corrected
by those concerned, but in order to secure as
great accuracy as possible a revised proof will
be sent in the early autumn.
This letter is written with a view to secur-
ing biographical sketches from those living in
North America who have carried on research
work in the natural or exact sciences but who
have not received proof of a sketch for cor-
rection. Some of those who were asked to
send the information required did not reply
even in answer to a second and third request,
and there are, of course, many who should be
ineluded in the work but who for one reason
or another did not receive the request for
information.
It is intended that each biographical sketch
shall contain information, as follows:
1. The full name with title and mail address,
the part of the name ordinarily omitted in corre-
spondence being in parentheses.
2. The department of investigation given in
italics.

6. Temporary and minor positions.
7. Honorary degrees and other scientific honors.
8. Membership in scientific and learned socie-
ties.
9. Chief subjects of research, those accomplished
being separated by a dash from those in progress.
The undersigned will be under great obli-
gations to those men of science who will send
him biographical sketches of themselves or
who will secure sketches from those who
should be included in the work—those who
live in the United States, Canada, Newfound-
land, Mexico or Cuba, and who have con-
tributed to the advancement of one of the
following sciences: mathematics, astronomy,
physics, chemistry, geology, botany, zoology,
pathology, physiology, anatomy, anthropology,
psychology.
The compiler of the book hopes that any
assistance given him to make it as complete
and accurate as possible will be at the same
time a contribution to the organization of
science in America.

SPECIAL ARTICLES.
THE NOMENCLATURE OF TYPES IN NATURAL
HISTORY.
PracticaL work in the arrangement and
eataloguing of ‘types’ and other museum
material has shown us that the present nomen-
clature is not yet sufficient for critically dis-
tinguishing all the different classes of such
specimens. Further, some of the terms which
have been proposed for the purpose are al-
ready employed in other ways: for instance,
homotype is in use in biology; monotype is
the name of a printing machine; autotype is
the term for a printing process. We wish,
therefore, to submit the following system of
nomenclature; and we hope that, in making
it more complete, we have provided a scheme
which will render efficient service in the
labeling and registration of types and typical
material.
900
The terms printed in broad-faced letters are
the additions or modifications for which we
are at present responsible. A fuller explana-
tion of all the terms will be found in the
‘Catalogue of the Type and Figured Speci-
mens of Invertebrate Fossils in the U. S.
National Museum,’ a work which has been
prepared by Charles Schuchert and is now
passing through the press; and the present
article gives a synopsis of the terms which it
has been found necessary to use in connection
with that and similar work.
We now make another suggestion. After
the different terms we have placed, in brackets,
the contractions which we propose should be
used in the actual marking of small specimens
to which it is impossible or inadvisable to
affix the full label. Our plan for such con-
tractions is this: For types of the first class,
two capital letters; for those of the second
class, one capital and one small letter; for
typical specimens, two small letters. s
In the definitions which follow, the term
‘ deseription’ indicates either a description by
words, or by a picture, or by both combined.
For the sake of accuracy we suggest that the
original description by words (type-descrip-
tion) be called the protolog, the original
description by a picture (type-figure), the
protograph. It is obviously more easy to
identify actual types from the latter than
from the former.
Primary types Proterotypes. Material
upon which original descriptions of species
are based.
Holotype [H. T.]. The only specimen pos-
sessed by the nomenclator at the time; the one
specimen definitely selected or indicated by the
nomenclator as the type; the one specimen
which is the basis for a given or cited proto-
graph.
Cotype (more properly Syntype) [S. T.].
A specimen of the original series, when there
is no holotype.
Paratype [P. T.]. A specimen of the origi-
nal series, when there is a holotype.
Lectotype [L. T.]. A cotype chosen,
subsequently to the original description, to
take the place which in other cases a holotype
occupies (Aeztdés, chosen, picked).
SCIENCE.
[N.S. Von. XXI. No. 545.
Supplementary types (Apotypes vice
Hypotype in use). Material upon which sup-
plementary descriptions of species are based.
Heautotype (vice Autotype in use)
[H. t.]. Any specimen identified with an
already described and named species, selected
by the nomenclator himself in illustration of
his species, such specimen not being identifi-
able as one of the proterotypes.
Plesiotype [P. t.] Any specimen iden-
tified with an already described and named
species, but not selected by the nomenclator
himself,
Neotype [N. t.]. A specimen identified
with an already described and named species,
selected to be the standard of reference in cases
when the proterotypes are lost, destroyed or
too imperfect for determination, such speci-
men being from the same locality and horizon
as the holotype or lectotype of the original
species.
Typical specimens (Icotypes) (2:zés, what
is like).* Material which has not been used in
literature, but serves a purpose in identifica-
tion.
Topotype [t. t.]. A specimen of a named
species from the locality of the holotype or
lectotype, in paleontology from the same local-
ity and horizon.
Metatype [m. t.]. A topotype identified
by the nomenclator himself.
Idiotype [i. t.]. A specimen identified
by the nomenclator himself, but not a topotype.
Homoeotype (vice Homotype, preoccu-
pied) [h. t.]. A specimen identified by a
specialist after comparison with the holotype
or lectotype (dors, resembling).
Chirotype [x. t.]. A specimen upon
which a chironym is based (chironym, a Ms.
name, Coues, 1884).
In addition to the above, we have the use of
the word ‘type’ in connection with genera—a
given species is the type of the genus. The
classification of such types is as follows:
TYPES OF GENERA (Genotypes).
Genoholotype. The one species on which
a genus is founded; or a series of species on
* éixdc, gen. étKdtoc, evko for evkoto, to make. Ico

which a genus is founded, the one species
stated by the author to be the ‘ type.’
Genosyntype. One of a series of species
upon which a genus is founded, no one species
being the genoholotype.
Genolectotype. The one species sub-
sequently selected out of genosyntypes to
become the ‘ type.’ CHARLES SCHUCHERT,

SUMMER MEETING OF SECTION E.
Section E of the American Association for
the Advancement of Science will hold a sum-
mer meeting at Syracuse, N. Y., July 19-22.
Arrangements have been made for making the
meeting enjoyable and profitable to all mem-
bers of the section. The vicinity of Syracuse
is one of great interest in several branches of
geology: the fossiliferous rocks of the New
York series are well exposed in many ravines;
the surface shows most of the phenomena of
chief interest in glacial geology; the pre-
glacial and the modern topography have been
worked out by specialists, and the economic
geology of the district is important. The chief
study in the field during the meeting will be
the gorges and lakes of the glacial drainage,
which are the most novel features of the dis-
trict.
In making its plans for the meeting the
sectional committee has accepted the cordial
invitation of the committee having in charge
the joint summer courses in geology for several
eastern universities and colleges to hold a
meeting in conjunction with the summer
school.
The following program may now be pro-
visionally announced:
Wednesday, July 19, 8.00 p.m—The section
will meet informally for the purpose of organ-
ization and of listening to short addresses by
the officers of the section, the state geologist
and others. Professor T. C. Hopkins, of Syra-
cuse University, will discuss local geology.
Thursday, July 20.—F¥ield day with picnic
lunch. The section will visit the Jamesville
Lakes, the ‘fossil cataracts’ and the several
glacial stream channels in the vicinity of

PRIZE FOR A METHOD OF SETTING DIA-
MONDS FOR CUTTING.
ConsiwerRING the fact that the setting and
resetting of diamonds for cutting purposes
involves the use of an alloy, consisting of tin
902
and lead, the handling of which has been as-
certained to produce injurious effects, 7. e.,
lead-poisoning, the government of the Nether-
lands has decided to open a competition under
the following conditions.
The government desires a medium for the
setting and resetting of diamonds to be cut
—which needs not necessarily be an alloy—
the use of which can not produce effects detri-
mental to the health of those handling the
same, or an elaborate project of altering the
method now in use, in such a manner that no
such injurious effects can be produced.
The following requirements have further to
be fulfilled:
1. The mediuin or the method must be
practicable for all sizes and shapes of dia-
monds in the following branches of the dia-
mond industry, viz., brilliants, roses and so-
called non-recoupés, now being cut in the
Netherlands.
2. The application must be such as to be
learned by the workmen, used to the present
method of work, without any great difficulty,
while the setting and resetting must not re-
quire more time, or considerably more time
than is usual now.
3. The application and use must not entail
considerable pecuniary outlay.
The Minister of the Interior has appointed
a committee of experts to consider the an-
swers submitted, and to award the prize. The
answers must be written in either the Dutch,
French, English or German languages, and
must be accompanied by samples or objects to
enahle the committee to form an opinion
about the practical value of the invention, as
also of a legibly written address of the com-
petitor.
The answers, and the samples or objects
pertaining thereto, must be sent carriage paid,
and if sent from foreign countries duty paid,
before January 1, 1906, to Professor Dr. L.
Aronstein, chairman of the committee, Chem-
ical Laboratory of the Polytechnic School,
Delft, Holland.
The prize to be awarded for a complete
solution of the problem is six thousand florins.
The committee is empowered to divide the
prize among different competitors, or to par-

tially award the prize in case of a partial
solution of the problem, for instance if it is
applicable to one of the above-named branches
of the diamond industry. The committee is
also empowered to prescribe certain condi-
tions, to be fulfilled by the competitor, before
awarding the prize.

Tue India correspondent of the Lancet
writes: “The plague epidemic continues with
unabated virulence. For the week ending
April 22 54,602 deaths were recorded, as com-
pared with 51,786 for the preceding seven
days. The death-roll for 1905 promises to
exceed all former records. In 1901 the total
deaths from plague were returned at 273,679,
in 1902 the number rose to 577,427, in 1903
904
it reached 851,263 and in 1904 it was 1,022,299.
From January 1 of the present year up to
April 15 the number of fatal cases is reported
at 576,366, and it is very doubtful whether
these figures tell the whole truth. Of the
total of 64,214 seizures with 54,602 deaths
during the week ending April 22 the Bombay
presidency had 3,497 cases and 2,787 deaths;
Madras, 65 cases and 65 deaths; Bengal, 4,993
eases and 4,351 deaths; the United Provinces,
18,249 cases and 16,637 deaths; the Punjab,
33,162 cases and 27,362 deaths; Burma, 183
cases and 175 deaths; the Central Provinces,
223 cases and 175 deaths; Mysore state, 50
cases and 40 deaths; Haidarabad state, 401
cases and 316 deaths; Central India, 117 cases
and 84 deaths; Rajputana, 2,924 cases and
2,406 deaths, and Kashmir, 359 cases with 215
deaths. These detailed figures will show how
the disease has extended over the country and
the heavy mortality of the cases. The mortal-
ity is higher this week in the Punjab by 3,420,
in the United Provinces by 753, in Rajputana
by 200, in Burma by 20, in Kashmir by 28, in
Bombay city by 132 and in Caleutta by 130.
The only noticeable decrease is in the districts
of Bengal, where the epidemic seems to be '
abating. In this area, however, the outbreak
occurred earlier in the season. During the
present outbreak the anti-plague serum from
the Pasteur Institute in Paris has been some-
what extensively used for the treatment of
cases both in Bombay and Calcutta, and, al-
though it is early to form a definite opinion,
numerous individual reports would seem to
show its value.

A CHAPTER, ALMOST UNIQUE IN THE
FASCINATING HISTORY OF LATTER-DAY
SCIENTIFIC EXPLORING EXPEDITIONS
ANTARCTICA, or
Two Years Amongst the Ice of the South Pole
By Dr. N. OTTO G. NORDENSKJOLD ana
Dr. JOHAN GUNNAR ANDERSSON
Dr. Nordenskjéld’s was one of the expeditions planned at the International
Geographical Congress of 1895, by which a concerted attack was made upon this
enormous unknown tract lying around the South Pole. The part assigned to
the Antarctic was to approach the east coast of the frozen southern land early in
the autumn of 1901, penetrate as far southward as possible and land a winter-
ing party of six under Dr. Nordenskjéld himself. She was then to return to the
Falkland Islands and Tierra del Fuego, picking up the party in the following
spring. But the next year proved the coldest and hardest yet experienced in
point of ice conditions. The Antarctic was unable to reach the wintering-place
again. Dr. Andersson with two companions attempted to reach it over the ice.
The ship tried to force a way farther to the east. Both attempts failed ; the
vessel was nipped by the ice and sank ; and all three parties, isolated from each
other, had to spend a second enforced winter in those regions,
Altogether the book forms as thrilling a narrative of scientific adventure as
can be found—all its adverse fortunes seeming to have but enhanced the value
of the scientific and geographical observations obtained by the expedition and
made far more perfect by being continued through so long a period.
Flandsomely illustrated with coloured plates,
maps and reproductions from photographs.

Columbia University
in the Wity of Hem Bork
; Columbia University includes both a college and a university in the strict sense of the words. The college is Colum-
oia College, founded in 1754 as King’s College. The university consists of the Faculties of Law, Medicine, Philosophy,
Political Science, Pure Science and applied Science.
The point of contact between t
e college and the university is the senior year of the college, during which year
students in the college pursue their studies, with the consent of the college faculty, under one or more of the faculties of the
university.
Barnard College, a college for women, is financially a separate corporation ; but educationally, is a part of the system
of Columbia University.
Teachers College, a professional school for teachers, is also, financially, a separate corporation; and also, educa-
tionally, a part of the system of Columbia University.
Each college and school is under the charge of its own faculty, except that the Schools ot Mines, Chemistry, Engi-
neering and Architecture are all under the charge of the Faculty of Applied Science.
For the care and advancement of the general interests of the university educational system, as a whole, a Council
has been established, which is representative of all the corporations concerned.
I.. THE COLLEGE,
Columbia College offers a course of four years, leading to
the degree of Bachelor of Arts. Candidates for admission to
the college must be at least fifteen years of age, and pass
an examination on prescribed subjects, the particulars con-
cerning which may be found in the annual Circular of
Information.
Barnard College, founded in 1889, offers for women a
course of four years, leading to the degree of Bachelor of
Arts. Candidates for admission to the college must be at
least fifteen years of age, and pass an examination on pre-
seribed subjects, the particulars concerning which may be
found in the annual Circular of Information.
II. THE UNIVERSITY.
In a technical sense, the Faculties of Law, Medicine,
Philosophy, Political Science, Pure Science, and Applied
Science, taken together constitute the university. These
faculties offer advanced courses of study and investigation,
respectively, in (a) private or municipal law, (b) medicine,
(ce) philosophy, philology and letters, (d) history, economics
and public law, (e) mathematics and natural science, and (/)
applied science. Courses of study under all of these facul-
ties are open to members of the senior class in Columbia
College. Certain courses under the non-professional facul-
ties are open to women who have taken the first degree.
These courses lead, through the Bacheélor’s degree, to the
university degrees of Master of Arts and Doctor of Phi-
losophy. The degree of Master of Laws is also conferred
for advanced work in law done under the Faculties of Law
and Political Science together.
Ill. THE PROFESSIONAL SCHOOLS.
The faculties of Law, Medicine and Applied Science, con-
duct respectively the professional schools of Law, Medicine,
and Mines, Chemistry, Engineering and Architecture, to
which students are admitted as candidates for professional
degrees on terms prescribed by the faculties concerned. The
faculty of Teachers College conducts professional courses
for teachers, that lead to a diploma of the university.
1. The School of Law, established in 1858, offers a course
of three years, in the principles and practice of pee
and public law, leading to the degree of Bachelor of Laws.
2. The College of Physicians and Surgeons, founded in
1807, offers a course of four years in the principles and practice
of medicine and surgery, leading to the degree of Doctor ot
Medicine.
3. The School of Mines, founded in 1863, offers courses ot
study, each of four years,leading to a professional degree, in
mining engineerin and in metallurgy.
4. The Schools of Chemistry, Engineering and Architect-
ure, set off from the School of Mines in 1896,offer respect-
ively,courses of study,each of four years,leading to an appro-
priate professional degree, in analytical and applied chem-
istry ; in civil, sanitary, electrical and mechanical engineer-
ing; and in architecture.
5. Teachers College, founded in 1888 and chartered in
1889, was included in the University in 1898. It offers the fol-
lowing course of study: (a) graduate courses leading to the
Master’s and Doctor’s diplomas in the several departments
of the College: (b) professional courses, each of two years,
leading to the Bachelor’s diploma for Secondary Teaching,
Elementary Teaching, Kindergarten, Domestic Art, Domes-
tic Science, Fine Arts, Music and Manual Training ; (c) a col-
legiate course of two years, which, if followed by a two-
year professional course, leads to the degree of Bachelor
of Science. Certain of its courses may be taken, without
extra charge, by students of the University in partial fulfill-
ment of the requirements for the degrees of Bachelor ot
Arts, Master of Arts, and Doctor of Philosophy.
The price of the University Catalogue is twenty-five cents
postpaid. Detailed information regarding the work in any

THE RELATIONS OF PUBLIC HEALTH
SCIENCE TO OTHER SCIENCES.*
“ PHYSICAL science is one and indivisible. Al-
though for practical purposes it is convenient to
mark it out into the primary regions of physics,
chemistry and biology, and to subdivide these into
subordinate provinces, yet the method of investi-
gation and the ultimate object of the physical in-
quirer are everywhere the same.”—Huxley.
Physical seience is one and indivisible;
that, as I understand it, is the key note of
this great congress, of which public health
science forms one section, and as I am in-
vited to eonsider, in the brief space of
forty-five minutes, the relations of public
health science to other sciences, I shall take
the lberty of selecting from the whole
number of ‘other sciences’ only a few, the
relations of which to public health science
seem to me for one reason or another espe-
cially important at the present time. I
accept the term public health science with-
out hesitation, for any division of human
knowledge which has worked out its own
laws with strict adherence to the rules of
inductive and deductive reasoning, as
public health science has done, and which
has reached results enabling it to predict
with accuracy, as public health science can
now predict, is entitled to a place and an
honorable place among the physical sci-
ences.
Public health science had its rise and a
considerable development in the eighteenth
century. Before that time numerous pro-
cedures tending to protect or promote the
pubhe health had, indeed, at one time or
* Address before the International Congress of
Arts and Science, St. Louis Exposition. °

another existed, but these were largely em-
pirical and quite as often directed to the
convenience of mankind as to their sani-
tary safety. In this class belong the
Mosaic code; the water supply introduced
into Jerusalem by Hezekiah; the sanitary
engineering of Empedocles; the Cloaca
maxima; the water supplies of ancient
Mycene and of Rome; and all the earlier,
and too often futile, forms of quarantine.
Even the art of inoculation for smallpox
was only an ingenious knack introduced
from the east, where it had been long used
empirically, and although it was a public
health measure now of the utmost interest
and capable at the time of great practical
service, it had until recently no scientific
basis, but belonged in nearly the same
class as the amulets and charms, the pray-
ers and incantations, of the superstitious.
It was not until the middle of the eight-
eenth century, namely, in 1767, that Sir
George Baker, by the use of the methods of
pure inductive reasoning, made the first
scientific discovery in public health science
in the subdivision of epidemiology, namely,
that the epidemic colic of Devonshire, Eng-
land, was due to an obscure poisoning by
lead conveyed through the common cider
used for drinking in that district. In
1774 the foundations of state hygiene and
sanitation were laid in consequence of the
patient investigations and startling revela-
tions of John Howard, by an act of Parlia-
ment providing for the sanitation of jails
and prisons. The beginnings of marine
hygiene and sanitation appear in 1776,
when Captain Cook, the navigator, was
awarded the Copley medal of the Royal
Society for his remarkable success in pro-
tecting the lives of his sailors on his sec-
ond voyage. In 1796 Edward Jenner,
working also in a strictly scientific man-
ner, and employing the methods of rigid
inductive research, laid securely for all

time the foundations of personal hygiene
and immunization, by showing how we can
produce at will such modifications of the
physiological resistance or susceptibility of
the human body as to make it immune to
smallpox.
The importance of these fundamental
and splendid discoveries, not only to the
public health of the time, but far more to
the development of public health science
in all the centuries to come, is inecaleu-
lable. Reduced to their lowest terms, we
have in these eighteenth century discoveries
the germs of some of the most important
divisions of public health science as it is
to-day, namely, (1) epidemiology, (2)
sanitation of the environment, and (3) m-
munization of the human mechanism, this
last the most marvelous phenomenon hith-
erto discovered in personal hygiene.
Time fails me to do more than name
some of the principal steps in the advance-
ment of public health science in the nine-
teenth century. We have, for example,
in 1802, the beginnings of factory hygiene
and sanitation; in 1829, the first municipal
water filter, one acre in area, constructed
for the Chelsea Company of London; in
1834, recognition of the important relation
of poverty to public health, in the famous
report of the Poor Law Commissioners of
that year; in 1839, the beginnings of reg-
istration and accurate vital statistics; in
1842, an important report on the sanitary
condition of the laboring population of
England; and in 1848, a similar report on
the health of towns; in 1854, for the first
time clearly taught, the lesson, even yet
not properly taken to heart, that drinking
water may be the ready vehicle of a ter-
rible epidemic of cholera. About 1860,
striking epidemics of trichinosis first came
into public notice, and here, also, belongs
the magnificent work of Pasteur, while in
1868, Lister, following in the footsteps of
a
JUNE 16, 1905.]
Pasteur, revealed to the world the basis of
true cleanliness in asepsis, and in 1876,
bacteriology became firmly established as
a science by Koch’s studies on anthrax.
The decade from 1880 to 1890 may be
ealled the golden age of ewxtiology, for in
these years were discovered the hitherto un-
known parasitic microbes of typhoid fever,
tuberculosis, malaria, Asiatic cholera, diph-
theria and tetanus. The last decade of a
century which has well been ealled ‘the
wonderful,’ witnessed the discovery of
antitoxins by Behring and the beginnings
of serum therapy. The list is long, and I
have not mentioned nearly all of the dis-
coveries of capital importance, but because
of these and their fruits, I am in the habit
of saying to my students that with the
single exception of the changes effected by
the acceptance of the theory of organic
evolution, there has been no modification of
human opinion within the nineteenth cen-
tury more wonderful, or more profoundly
affecting the general conduct of human
life, than that in our attitude toward the
nature, the causation and the prevention
of disease—that is to say, toward public
health science.
No mere outline like this of the history
of public health science can possibly serve
to show how, like other applied sciences,
this one has not grown as a branch grows
from a tree, namely, from a large stem or
stock of knowledge, tapering out into thin
air, and with its latest growth its least and
weakest. That common simile in which
the various divisions of science are repre-
sented as branches of the tree of knowl-
edge, is a grotesque survival of a time when
neither trees nor science were understood.
No simile is perfect or even approximately
correet, but one better than the tree and
its branches for the origin and relation-
ships of any inductive science is that of a
river, rising from various and often ob-

scure sources, growing in size and impor-
tance as it proceeds both from the springs
within its own bed and by the entrance
and contributions of tributary streams,
and finally pouring its substance into
the mighty ocean of accumulated human
knowledge.
Up to the time of the establishment of
the registration of vital statistics in Eng-
land, in 1839, the stream of public health
science, although full of promise, was only
a slender thread, but when the results of
registration were fully enlisted in its
service it visibly widened and deepened.
Epidemiology, as has been said, had the
honor of giving birth to the science in
1767, and it added to its offspring a rich
endowment when, in 1854, Dr. John Snow
proved that the water of the Broad Street
well in London had caused an epidemic,
in which more than six hundred persons
died of Asiatic cholera. The stream of
public health science was still further en-
larged and quickened by the revelation in
and after the sixties of the simple causes
of numerous epidemics of trichinosis and
of typhoid fever, the latter sometimes
through milk. There was an extraordi-
nary popular awakening in England to
the importance of sanitation and public
health measures in the middle of the nine-
teenth century, but we look for some time
in vain for any marked inosculation be-
tween public health science and other sci-
ences, such as physics, chemistry, micro-
scopy, bacteriology, climatology, engineer-
ing or education. We have, to be sure,
minor contributions from the microscopists,
such, for example, as that from Dr. Has-
sall, who, in 1850, made a careful micro-
scopical examination of the water supply
of London and showed the presence in the
public drinking water of muscle fibers,
intestinal parasites and other materials,
plainly derived from sewage; but it was
908
not until Pettenkofer and his disciples, in
Germany, and Angus Smith and others, in
England, began their splendid chemical in-
vestigation that the tributary stream of
sanitary chemistry enlarged materially
that of public health science. In saying
this I do not forget that my late friend
and colleague, William Ripley Nichols,
whose solid contributions to sanitary chem-
istry were among the first in America, and
will always remain among the best any-
where, long ago pointed out that, as early
as 1789,
Foureroy studied the nature of ‘litharged’
wine, Berthollet (1801) the methods of preserving
water for long voyages, Chevreul (1846) various
chemical reactions which explain the hygiene of
populous cities, and (1856, 1862, 1870) methods
of preparing and preserving food; Graham and
Hofmann reported upon the use of acetate of lead
in sugar refining (1850), upon the London water
supply (1851), and upon the adulteration of pale
ales with strychnine (1882); Dumas was inter-
ested in many sanitary matters and made, among
others, reports on the mineral waters of France
(1851), on the water supply of Paris (1859), on
the treatment of sewage (1867), and on the pres-
ervation of food (1870-72); Wurtz was for a
number of years president of the Comité con-
sultatif dhygiéne and a year before his death was
president of the Société de médecine publique.
His investigations and reports on sanitary sub-
jects are numerous—on the disposal of the waste
from distilleries and sugar-refineries, on the
colors employed on German toys and in articles
of food, on the adulteration of wines, ete.
Other names will oceur to us—such as those of
Sir Henry Roscoe, Sir Frederick Abel and Dr.
Williamson, who served on the Noxious Vapours
Commission of 1876; of Frankland, who gave
years of service to the Rivers Pollution Com-
mission of 1868 and in connection therewith de-
vised an elaborate system of water analysis; we
think also of Schutzenberger devising a method
for the determination of oxygen dissolved in
water (not, to be sure, simply for sanitary pur-
poses), Mallet studying the various methods of
water analysis, Remsen studying the organic mat-
ter in the air, and Leeds the practical effect of
charging with oxygen (or rather with air) water
used for purposes of domestic supply.*

[N.S. Von. XXI. No. 546.
I dwell intentionally upon the service of
sanitary chemistry to public health science
previous to the rise of bacteriology, because
I believe that, dazzled as we have been
and still are by the blazing achievements
of bacteriology, beginning, let us say, with
the discovery of the microbe of tuberculosis
by Koch in 1882, students of public health
science have been too much inclined to un-
derrate the past services and present rela-
tive importance of sanitary chemistry. I
know of few more important contributions
to public health science, even since 1882,
than the chemical work of the State Board
of Health of Massachusetts under the able
direction of my friend, Professor, after-
wards President, Drown (the successor of
Nichols) and his associates and successors ;
or that of another friend, the late Professor
Palmer, of the University of Illinois, whose
chemical studies of the rivers of Illinois
will long remain a monument to a life full
of promise and too soon eut short, or that
of still another friend, Professor Kinniecutt,
who fortunately is still engaged in fruit-
ful work.
I have perhaps said enough, though it
would be difficult to say too much, of the
magnificent contributions to public health
science of Pettenkofer and his disciples in
sanitary chemistry; but the work of these
investigators in sanitary physics and espe-
cially the physies of the soil, of the atmos-
phere, of the walls of buildings, and of
heating and ventilation, in their relations
to the public health are quite as important,
and perhaps to-day even more neglected.
In view of the increased facilities for
transportation and the growing habit of
traveling, together with the tendency to
outdoor life, which seem to be character-
istic to-day of all civilized nations, the next
twenty-five years will probably see a re-

turn to the patient and exact studies of
the environment, such as the chemists and
physicists began, and have in some meas-
ure continued, since the middle of the nine-
teenth century. These studies will be
directed largely to further knowledge and
- control of the environment, but they will
not end there, for personal hygiene, owing
to recent advances in physiology, is to-day
one of the most inviting fields for work
and education, and I hardly need to point
out to a company of experts that the proper
eare and right use of the individual human
mechanism reacts favorably and funda-
mentally upon the public health no less
truly or effectively than an improved con-
dition of the environment or of the public
health tends to promote the welfare and
long life of the individual.
The sphere of hygiene may be divided,
as it often is, into the two hemispheres,
public hygiene and personal hygiene, or it
may be cut into one portion dealing chiefly
with the human mechanism and its opera-
tion (personal hygiene), and another por-
tion dealing chiefly with the environment
of that mechanism (sanitation). The
time has gone by when any one person can
safely undertake to deal with the whole
sphere of hygiene. The physiologist and
the physician must in the future leave to
the architect and the sanitary engineer
such subjects as housing, heating and venti-
lation, water supply and sewerage, pre-
cisely as the sanitary engineer has never
presumed to deal with foods and feeding,
vaccines and antitoxins, exercise, sleep and
rest. The former subjects deal chiefly with
the control of the environment, the latter
subjects chiefly with the control of the in-
dividual, and sanitation and hygiene must
henceforward be regarded as_ separate
hemispheres of the science of health.

construction, and the heating and ventila-
tion of buildings, has dorie and is doing
much of interest and importance to the
student of public health science. For my
own part, I am continually more and more
impressed with the fact that the air supply,
especially for the modern civilized and too
often sedentary form of mankind, is in the
long run quite as important as the water
supply, the milk supply or any other
supply. Surely, we ean not be too careful
of the purity of a substance which we
take into our bodies oftener, and in larger
volume, than any other, and which has
come, rightly no doubt, and as the result
of long and painful experience, to be
known as the very breath of life. I am
well aware that human beings may sur-
vive and seemingly thrive, even for long
periods, in bad air, but I am certain that
for the best work, the highest efficiency,
the greatest happiness and the largest life,
as well as for perfect health, the very best
atmosphere is none too good. Hence I
believe that the permeability of the walls.
of houses and other buildings, and the
heating and ventilation of dwellings, school
houses, churches, halls and other public
places, require, and in the near future
will receive, a much larger share of our
attention than they have to-day.
In an age characterized by urban life and
possessing sky-scrapers, tenement houses
and other huge bee-hives, in which human
beings aggregating vast numbers spend a
large part of their lives, buildings require
for their proper construction, lghting,
heating, air supply, water supply, gas sup-
ply and drainage, the scientific services not
only of architects, but of engineers, and
such publie buildings form one small sec-
tion of the aid which modern engineering
science 18 now everywhere rendering to
public health science. The present has
rightly been called an ‘age of engineering,’
910
and to no other science, excepting only
medicine itself, is public health science to-
day more indebted than to engineering
science. I have referred above to the con-
struction of the first municipal filter at-
tached to a public water supply as that of
the Chelsea Company of London, con-
structed in 1829. How different is it to-
day! Not only nearly the whole of Lon-
don, but also Berlin and Hamburg, and a
thousand lesser cities all over the civilized
world, are now protected more or less per-
fectly from epidemics of typhoid fever,
Asiatic cholera and other water-borne dis-
eases by vast municipal filters, ingenious
and scientific in design and costly in con-
struction, the work of skillful and faithful
engineers, and monuments, more precious,
if less enduring, than brass, to the con-
tributions of engineering science to public
health science. Innumerable storage reser-
voirs and vast distribution systems for sup-
plies of pure water also bear witness to the
enormous debt which public health science
owes to engineering science, as do proper
street construction and, still more, those
splendid systems of sewerage with which
so many modern cities are equipped, and
which not only serve to remove quickly the
dangerous liquid waste of human and ani-
mal life, but also keep low and wholesome
the level of the ground water, reducing
dampness and promoting dryness of the
‘environment, and thereby strengthening
that physiological resistance by means of
which the human mechanism fights against
the attacks of infectious disease. Nor do
the services of engineering science end here,
for the fluid content of the sewers must
always be safely disposed of, and sewage
purification is to-day a problem of engi-
neering science no less important or diffi-
cult than that of water purification. These
same processes of the purification of water
and sewage are matters of so much moment

[N.S. Von. XXI. No. 546.
in public health science that in almost every
country experiment stations are now main-
tained at public and private expense for
the purpose of working out the most prac-
tical and most scientific methods of purifi-
cation.
In no respect have the services of engi-
neering science to public health science
been more conspicuous than in the applica-
tion and the further study of the principles
involved in the processes of water purifica-
tion. It has lately been shawn, for ex-
ample, that the introduction of pure water
supplies has in many eases so conspicuously
lowered the general death rate as to make
it impossible to escape the conclusions (1)
that the germs of a greater number of in-
fectious diseases than was formerly sup-
posed are capable of prolonged life in, and
ready conveyance by, public water sup-
plies, and (2), as a promising possibility,
that as the result of the greater purity of
the water supply the physiological resist- —
ance of the consumers of pure water sup-
plies is enhanced, in some manner as yet
unknown; the net result being that the gen-
eral death rate is lowered to such an extent
as to lead to a rapid increase of population
in communities previously stationary or
multiplying far less rapidly. In the case
of the city of Lawrence, Mass., for example,
I have recently had the privilege of exam-
ining the results of studies by the dis-
tinguished hydraulic and sanitary engi-
neer, Mr. Hiram F. Mills, which show that
since the introduction of a municipal filter,
which purifies the water of the Merrimac
River supplying water to the citizens of
Lawrence, while the population has in-
creased nearly seventy per cent., the total
number of deaths remains about the same
as it was ten years ago. Mr. Mills con-
cludes from the results of his studies—and
I see no escape from his conclusions—that
the introduction of the municipal filter has
JuNE 16, 1905.]
not only saved the lives of thousands of
citizens, but has also caused the population
to increase to a point much beyond any
which it would have reached had the city
continued to use, unpurified, the sewage-
polluted water of the Merrimac River. A
demonstration of this sort shows how easily
the diminishing increase of population un-
der a lower birth rate may sometimes be
counteracted without resort to that fish-
like spawning which seems to be the only
remedy of those who are terrified by ‘race
suicide,’ so called. Moreover, it is hardly
necessary to point out that such a dimin-
ishing death rate means a far more rapidly
diminishing morbidity rate—in other words,
it means a heightened working efficiency
of the population as a whole, and it must
not be forgotten that for most of the results
obtained in the scientific purification of
water supplies we are indebted to the sci-
ence of engineering.
On the other hand, we must observe that
engineering science, so far as water puri-
fication is concerned, is as yet only in its
infaney. and by no means thus far alto-
gether satisfactory. In the United States,

have resulted from the defective operation
or construction of municipal filters, and
while much has been done, it is clear that
much still remains to do. In this connec-
tion it should be said that public health
science in the United States suffers con-
stantly and severely from an unsatisfac-
tory condition of the science and art of
administration or government in many
American cities. Public health works are
too often neglected, delayed, mismanaged
or built at extravagant cost, to the sanitary
and economic damage of the people as a
whole, and the tendency is far too common
to place the care and operation of costly
devices or systems in incompetent hands.
SCIENCE.

I can not here dwell, as long as I should
like to do, upon the mutual relations of
public health science and the sciences of
legislation and administration. Speaking
of my own country alone, I must confess
that we are still very deficient in the appli-
cations of these sciences. We have not
even a national board of health, although
we have, fortunately, in the Public Health
and Marine Hospital Service a strong sub-
stitute for one. The peculiarities of our
democratic and republican government
have hitherto made it impossible for the
people of the United States to secure either
from federal authorities or from more
local sources that measure of paternal sani-
tary and hygienic protection which they
ought to have, and it is the duty of every
American worker in this field to bend his
energies toward a better organization of
the public health service in every direction,
municipal and state as well as national.
The appointment in 1886 of a distinguished
hydraulic engineer to membership on the
State Board of Health in Massachusetts
marked an epoch, so far as America is con-
cerned, in both sanitary legislation and
administration. This appointment was a
formal recognition on the part of the public
of the necessity of a larger proportion of
engineering science in matters relating to
the public health, and the results have justi-
fied the new procedure. It is now, for-
tunately becoming less rare in America to
secure the services of engineers upon such
boards and there can be no question that
participation of the expert laity with med-
ical men is likely to be extended, probably
far beyond our present ideas.
In a notable discourse before the Inter-
national Medical Congress at the Centen-
nial Exposition held at Philadelphia in
1876, Dr. Henry P. Bowditch, of Boston,
one of the pioneers of hygiene and sanita-
tion in America, divided the century then
912 SCIENCE.
closing, as to its relation to public health
science, into three periods, the first, from
1776 to 1832, a period of reliance upon
authority and upon drugs; the second,
from 1832 to 1869, a period of true scien-
tifie observation; the third, from 1869 on-
wards, an epoch in which the medical pro-
fession is aided by the laity and _ state
hygiene is inaugurated. Dr. Bowditch has
much to say of the desirability of a wider.
cooperation of the laity in state hygiene
and remarks: ‘In all that tends to the
promotion of state hygiene hereafter thé
laity will naturally and cordially cooperate
with the [medical] profession.’ The his-
tory of public health science shows Dr.
Bowditch’s prediction to have been well
erounded. The names of John Howard
and Captain Cook in the eighteenth cen-
tury, and of Edwin Chadwick, John Simon
and Louis Pasteur (not to mention a host
of lesser workers) in the nineteenth cen-
tury, show conclusively that public health
science has been, even from the start, by
no means confined to medical men. We
may go further and say that even when
forwarded. by medical men these have sel-
dom been busy practitioners. Sir George
Baker and Jenner were, it is true, of this
class, but not Pettenkofer or Koch or Ross
or Billings or Reed.*
Reflections of this sort naturally lead to
a consideration of the reciprocal relations
of public health science and the science of
education. I do not need to dwell upon
the beneficial effects of public health sci-
ence upon the hygiene and sanitation of
school children or school houses. These
benefits have long been emphasized by sani-
tarians and sanitary reformers, and are
sufficiently obvious. The reverse of the
picture, however, is by no means so well
* “uring the course of an epidemic physicians
are too busy to make observations which require
much time or care, or to make more than brief
notes.”—J. 8. Billings.
[N.S. Vou. XXI. No. 546.
understood. Unless one is familiar with
the facts, it is difficult to conceive how little
impression the splendid progress which the
last fifty years have witnessed in public
health science has as yet made upon the
curriculum of education. From top to
bottom and from bettom to top the schools,
whether primary, grammar, high, normal,
technical, medical or any other class, are
recreant, inasmuch as they neglect almost
wholly any adequate training of their pu-
pils in the principles of public health sci-
ence, which are confessedly of such pro-
found importance to mankind. There is,
to be sure, just now a popular wave of en-
thusiasm touching the extermination of
tuberculosis, but in the United States, at
any rate, both schools and universities are
singularly negligent of their most element-
ary duties in this direction. Yet if what
I have said before is true, if the laity are
to participate from this time forward with
medical men in sanitary and hygienic
legislation and administration, if engineers
and medical men in particular are to serve
upon boards of health or in other executive
positions connected with publie works, then,
surely, it is the duty of the science of edu-
cation to lend its powerful aid and not to
fail to save the lives and health of the
people as these can be saved to-day, but
always to promote that public health and
that large measure of consequent happiness
which can probably be more easily and
quickly accomplished in this way than in
any other.
As to the function of medical education
and engineering education in respect to the
dissemination of public health science, I
shall say only a word. In spite of the
reiteration by medical men of their belief
in the importance of hygiene and pre-
ventive medicine as a part of the equip-
ment of the medical profession, it is a
significant fact that in America even the
JUNE 16, 1905.]
best medical schools devote very little time
to any adequate instruction in these sub-
jects. It may be that this is wise and that
the pressing necessities of practical medi-
cine forbid any extended instruction in
public health science. I am willing to be-
lieve, if I must, that this may be the ease;
but if it is, then the community must look
for the most part elsewhere than to medical
men for adequate investigation, legislation
and administration of public health science.
Medical men, must, of course, always par-
ticipate in the work, in connection, particu-
larly, with the control of epidemics and in
those forms of preventive medicine which
have to do with vaccines, serums and other
means of modifying the vital resistance of
the human body. But as regards the care
and control of the environment, medical
Knowledge is not indispensable, and the
entrance of the engineer and the sanitary
expert upon the field, as foretold by Dr.
Bowditch nearly twenty years ago, is to-
day a conspicuous, and probably a whole-
some, fact. As to the attitude of engineer-
ing education toward public health science
there can be no question. If what I have
said before is true, then engineers are
bound in the future to take constantly a
larger and more important part in public
health work, and must be informed, and
if possible trained, accordingly. Moreover,
as regards both medicine and engineering,
the problem is by no means insoluble, for a
very short course of instruction rightly
given would easily ineuleate the necessary
fundamental principles, while electives or
post-graduate work might enable those few
whose tastes led them in this direction to
investigate and specialize and more thor-
oughly prepare themselves for public serv-
ice.
I can not treat, nor do I need to treat, as
thoroughly as I would be glad to do, the
mutual relations existing between medical

science, especially the science of medical
bacteriology, and public health science.
These are already sufficiently obvious and
well known.
ical men have served, often devotedly and
sometimes heroically, in the cause of public
health science. I take it, however, that
since we have in this congress and in our
own department a section of preventive
medicine, I may pass over without com-
ment this part of my subject.
As regards sanitary bacteriology, how-
ever, the relations existing between this
and public health science are so funda-
mental, so extensive and so important, not
only on the medical, but also on the engi-
neering side, that although we have also
in this congress under the department of
biclogy, as is entirely proper, a section of
bacteriology, I may linger at this point for
one moment. The bacteria and other
microscopic forms of plant and animal
life, all of which are conveniently included
under the term microbes, have so lately
begun to be understood and appreciated
that we must still emphasize their extreme
importance. The discoveries of the botan-
ists and zoologists and revelations of the
microseopists in this domain are compar-
able, in their importance to public health
science, with nothing less than the revela-
tions of the telescope to astronomy. As-
tronomy had, indeed, existed long before
the invention of the telescope, and public
health science, as we have shown above,
had its beginnings nearly a century before
any considerable progress had been made
in micro-biology. But it is not too much
to say that the developments in miero-
biology since Pasteur began his work have
not only revolutionized our ideas of the
nature of the infectious diseases, but have
also placed in our hands the key of their
complete control.
Concerning the relations of physiology
From time immemorial med-
914
to publie health science, I must not fail to
speak. Here is a field absolutely ripe for
the harvest, but one in which the harvesters
are as yet very few. I have lately had
occasion to examine somewhat carefully the
present condition of our knowledge of per-
sonal hygiene—which is nothing more (and
should be nothing less) than the applica-
tions of physiologial science to the conduct
of human life—with the result that I have
been greatly impressed with its vast possi-
bilities and promise. Man is a gregarious
animal, and mankind is to-day crowding
into cities as perhaps never before. More-
over, the industrial and commercial age in
which we live is characterized to an ex-
traordinary degree by the sedentary life.
Yet the sedentary life is almost unavoid-
ably an abnormal life, or at least it is a life
very different from that lived by most of
our ancestors. In the sedentary life the
maintenance of a high degree of physiolog-
ical resistance apparently becomes difficult,
and if the vital resistance of the community
in general is lowered then the public health
is directly and unfavorably affected, so
that considerations of personal hygiene
have a direct bearing upon the science of
public health.
There are, to be sure, interesting and
suggestive symptoms of a wholesome reac-
tion, in America, at any rate, against the
evils of the sedentary life. Parks and
open spaces are being liberally provided;
puble and private gymnasiums are rapidly
coming into being; publie playgrounds are
thrown open in many of our cities, free of
expense to the laboring, but, nevertheless,
often sedentary, population; vacations are
more than ever the fashion; sports and
games are everywhere receiving increasing
attention; while publie baths and other de-
vices for the promotion of personal hygiene
are more and more coming into being. All
this is as it should be, but all is as yet only
SCIENCE.
[N.S. Vou. XXI. No. 546.
a beginning. Here, again, the science of
education is sadly at fault and in the direc-
tion of educational reform as regards per-
sonal hygiene lies immense opportunity for
a contribution to public health science.
The science of statistics, which has done
great service in public health science in
the past, is likely to do much more in the
future. Without accurate statistics of
population, mortality and the causes of
sickness and death, the science of epi-
demiology is impotent, and the efficiency
or inefficiency of public health measures
can not be determined. And yet in
ignorant hands statistics may be worse
than useless. It is a matter for congratu-
lation to Americans that we now have in
Washington a census bureau permanently
established and under expert supervision,
but until the various states and cities of
the United States follow this excellent ex-
ample of their Federal Government, one
of the most important aids to public health °
science will continue to be wanting, as is
unfortunately too often the case to-day not
only in America, but in many other parts
of the civilized world.

Manual of the Trees of North America (Exclu-

‘The Silva of North America,’ in fourteen
massive quarto volumes, and including de-
scriptions and figures of 585 species of trees.
———rerrrrr
JUNE 16, 1905.]
While this must for centuries be the standard
work on our native trees, its bulk and cost
preclude its use elsewhere than in the herba-
rium, museum or library, and it was impera-
tive that the same author should prepare a
handy field (or rather, forest) manual which
should give to a much larger number of people
the opportunity of studying our forest trees.
This has now been done in an admirable
manner in the Manual which made its ap-
pearance some time in March of the present
year.
The book opens with a synopsis of the sixty-
one families of plants included, the sequence
being that of Engler and Prantl’s ‘ Die Natiir-
lichen Pflanzenfamilien,’ and this is followed
by an analytical key to the families, based on
the characters of the leaves. Then follows the
descriptive manual proper, in which after a
clear and pretty full characterization of each
family there is given a conspectus or analytical
key to the North American genera. The char-
acters of each genus are set forth much more
fully than they are in the usual botanical
manuals, and a paragraph is usually appended
giving geographical, numerical and economic
data. A convenient key enables the student to
readily find the particular species in which he
is interested. :
The specific descriptions leave nothing to be
desired, usually including full descriptions of
the leaves, flowers, fruits, seeds, the tree as a
whole, its winter buds, bark and wood, and are
followed by concise accounts of their natural
geographical distribution, and the extent of
their cultivation for ornamental and other pur-
poses. With each species is a figure of the
characteristic features of the species, usually
the foliage, flowers and fruit. By means of
these figures alone one can identify nearly
every species.
The book is thus thoroughly satisfactory,
and must at once become a standard among
systematic manuals. It will appeal to the gen-
eral botanist as a distinct and notable contri-
bution to the literature of systematic botany,
and at the same time it will be recognized by
students of forestry as an indispensable hand-
book. For the latter, in this day of forestry
schools and forestry courses of study in the

colleges and universities, it is indeed fortunate
that this manual has made its appearance.
Without it North American dendrology was a
most difficult subject for both professor and
student, on account of the scattered and unco-
ordinated descriptions in the botanical manu-
als—the ‘Silva’ being quite too expensive a
work for every-day use by students. This
difficulty is now wholly removed by the pub-
lication of the manual.
Looking over the families which include
North American trees, one finds that the coni-
fers number 90 species and varieties; the palms,
10; Liliaceae, 9; the Juglandaceae, 15; Sali-
caceae, 32; Fagaceae, 52; Rosaceae, 169 (of
which 132 are species of Crataegus); Legu-
minosae, 34; Aceraceae, 17; Cornaceae, 8;
Ericaceae, 9; Oleaceae, 19. The generic and
specific nomenclature is modern, so that one
finds Tumion (instead of Torreya), Hicoria
(instead of Carya), Toxylon (instead of Mac-
lura), Malus (instead of Pyrus), Sassafras
sassafras (instead of Sassafras officinale), and
Catalpa catalpa (instead of Catalpa bignonio-
ides). No attempt is made to cite synonyms,
the author evidently assuming that the student
might well trust him in the selection of the
oldest available name. The author has added
a handy glossary of technical terms, and the
volume closes with a very full index in which
English and Latin names are arranged in a
single alphabetical series, thus avoiding the
nuisance of two indexes, one for the common
and another for the scientific names.
This book suggests to one that Professor
Sargent is the man to give us a similar book
devoted to the exotic trees (and probably
shrubs also) of which so many are now given
in this country.

The Journal of Comparative Neurology and
Psychology for May contains an article of
100 pages, entitled ‘The Morphology of the
Vertebrate Head from the Viewpoint of the
Functional Divisions of the Nervous System,’
by J. B. Johnston, of West Virginia Univer-
sity. The ‘head problems’ have recently re-

ceived renewed study from the standpoints of
comparative anatomy and comparative em-
bryology by some of our ablest morphologists,
but none of these researches appears to give
adequate attention to the recent phases of the
doctrines of nerve components and the func-
tional subdivision of the system.
Professor Johnston reviews this literature ex-
haustively from the new point of view and in
the light of his own researches (partly not
before published), discussing the problems of
head morphology and segmentation with illus-
trative diagrams and tabular summaries. The
phylogeny of the organs of special sense is
diseussed fully with reference to their primi-
tive segmentation and their derivation from
more primitive types of sensory mechanisms.

As informal communications, Mr. L. C.
Graton exhibited photographs of Taughannock
Falls, New York, and Dr. F. E. Wright ex-
plained a new method of determining the opti-
cal character of minerals. The regular pro-
gram included the following papers:
The Ore Deposits of the Ouray Quadrangle,
Colo.: Dr. J. D. Irvine.
The ore-deposits are located in a small area
of about three and one half miles square in the
precipitous country in the near vicinity of
Ouray, Colo.
The rocks of the region comprise a series of
sedimentaries ranging in age from Algonkian
to Cretaceous, with included porphyries, while
the higher hills are capped by thick beds of
voleanic tuff.
The ores are classified as_ silver-bearing
fissure veins, gold-bearing fissure veins, re-
placement deposits in quartzite, replacement
deposits in limestone.
The silver-bearing fissure veins penetrate
the sedimentaries and pass occasionally up-
ward into the volcanic tuff. They carry
galena, tetrahedrite and some other sulphide
in a gangue of barite and quartz. Replace-
ments of limestone occur where beds of this
rock are penetrated by the fissures. The
silver values are present in the tetrahedrite.
The gold-bearing fissure veins are associated
with intrusive dikes of monzonite-porphyry,
and contain chiefly auriferous pyrite with
some chalcopyrite in a gangue of quartz and
erushed country rock.
The replacement deposits in quartzite are
flat shoots of gold-bearing pyrite with a little
galena and other sulphides which have been
deposited in quartzite. It is thought that they
owe their origin to alkaline waters that have
ascended to the quartzite through minute fis-
sures. The quartzite is fully replaced only in
the neighborhood of the fissures and is sur-
rounded by empty solution cavities in the
quartzite resembling those usually encountered
in the limestone beds. The ores range from
$30 to $600 in value. :
The replacement deposits in limestone are
of three kinds. One is in the limestone beds
along the courses of the normal fissure veins

where they form flat, lateral enrichments of
such veins.
2. Large flat bodies of silica and _ barite
with silver-bearing ores associated with

3. Deposits of gold-bearing ore composed of
an intimate mixture of pyrite and magnetite
with actinolite, quartz, epidote and other
minerals of supposed contact origin. This
class of deposit carries low values in gold and
is thought to have been deposited by replace-
ment together with the associated minerals by
circulating waters subsequent to the porphyry
intrusions.
The geological age of all of these ores is
Post Eocene.
Structure of the Great Plains and the Moun-
tains on their Western Margin: N. H.
Darton.
With this communication there was pre-
sented an illustration showing the configura-
tion of the Dakota sandstone under the Great
Plains and on the flanks of the uplifts west-
ward. This widespread formation has been
extensively explored in its underground dis-
tribution, by numerous deep wells, and its
outcrop area has been mapped so that the
structure of much of the region which it
underlies is ascertained. This structure was
shown by 100- and 500-foot contour lines and
it exhibits many notable features. In gen-
eral, under the Great Plains, the formations
have but little dip and wide areas are mono- -
clinal. The uplifts along the mountain border
and in southeastern Colorado are marked
features and it has been discovered that there
is a low anticline extending across north-cen-
tral Kansas and western Nebraska nearly
to the Black Hills. In the bottom of the
basins about Denver and northeast and north-
west of the Black Hills the Dakota sandstone
lies below sea level. In eastern South Dakota
it abuts against the Sioux quartzite and is
overlapped by Benton formation.
Two diagrams were exhibited, illustrating
the configuration of the Black Hills and Big-
horn Mountain uplifts by contour lines drawn
at the surface of Minnekahta limestone in the
former and Bighorn limestone in the latter.

Fault Phenomena Near Glen Echo, Md.: G.
K. Ginpert.
The locality is a disused quarry on the
north bank of the Chesapeake and Ohio Canal,
about one fourth mile east of Glen Echo. The
rock is gneiss. It is traversed by numerous
systems of joints, as many as twenty having
been noted. These are inclined in various
directions and at various angles. .The joints
of each system are approximately parallel,
with interspaces ranging from a few feet to
at least several yards. The joint surfaces
most broadly exposed are not true planes, but
show curvature. Many of the joints are evi-
dently surfaces of slipping, or fault planes,
the observed dislocations ranging from a frac-
tion of an inch to two or three feet.
The joint systems may be classed in two
series, of which one is younger than the other.
Many of the joint faces of the younger series
are slickensided, and some of the joints con-
tain veins of quartz. The older joints show
no slickensides and carry no yeins, although
there is independent evidence that they are
planes of faulting. Their surfaces have a

Where two fault planes of the older systems
intersect, each is dislocated by the movement
along the other, but the dislocated parts are
connected by a fluted surface suggestive of
an ogee molding. This phenomenon is sup-
posed to indicate simultaneous (or alterna-
ting) movement on the intersecting planes

of) the zone of flowage. Similar movement
in the zone of fracture produces splintering

THE CHEMICAL SOCIETY OF WASHINGTON.
Tue 159th regular meeting was held Thurs-
day evening, May 11, 1905, in the assembly
hall of the Cosmos Club.
The first paper, entitled ‘Chemical Glass-
ware,’ was presented by Mr. Perey H. Walker.
Analyses and tests of durability and solubility
of a number of beakers and flasks were given,
and samples of the various glasses shown.
The most suitable for chemical use were zinc
boro silicates, and may be distinguished by
permanent trade marks. Much of the lime
alkali silicate glass sold in this country is of
very poor quality.
The second paper, entitled ‘A Colorimeter
for General Use,’ was presented by Dr. Oswald
Schreiner. The speaker called attention to
the increasing use of colorimetric methods
for purely analytical and commercial purposes
for both organic and inorganic compounds,
and also for carrying on scientific studies in
physical, physiological, sanitary and agricul-
tural chemistry. A colorimeter of improved
form was then exhibited and described. The
parts coming in contact with the liquids are
entirely of glass, mounted in a camera of
wood. This instrument has the great ad-
vantage of speed and accuracy combined with
great versatility of application to colorimetric
solutions, together with simplicity in con-
struction.
The third paper, entitled ‘The Occurrence
. of Extractives in Apple Skin, was presented
by Mr. H. C. Gore. The quantities were
given in which apple wax and apple vitin
occur in the epidermis of the apple, both on
ripe apples and on apples examined at in-
tervals during growth. The method of an-
alysis of apple skins for apple wax and apple
vitin, stated briefly, consisted of extracting
the mare of the skin with petroleum ether,
followed by chloroform, the petroleum ether

moving the vitin. The extracted wax was
green or yellow colored, and melted at 59°-
60°. The crude vitin was a white powder
tinged with green or yellow and melted at
240°-250° C. The two varieties of summer
apples examined were poorer in these extract-
ives than the five varieties of winter apples.
The extractives were found to increase stead-
ily during the growing season. In case of
ripe winter apples the wax amounts to about
30 mgms. per apple, the vitin to about 60
mgms. The probable importance of such
studies in connection with the disease resist-
ance of fruits was discussed.

charge is altered by a change of capacity, the
position of the maximum point of the duration
curve is altered to correspond to the displace-
ment of minimum sparking potential of the
discharge.
Lengthening the spark gap and thereby in-
creasing the electrical intensity inside of the
vessel in which the discharge takes place
changes the form of the duration curve, and
when the electrical intensity is thus increased
above a certain amount the curve obtained is
completely altered in form. When the after-
glow in the rarefied air is allowed to diffuse
into a vessel cooled to liquid air temperature,
the duration curve is displaced some distance
towards the higher pressure and is also changed
in form, other conditions being the same;
otherwise, the duration of the afterglow, which
in the experiments was approximately thirty
seconds, was found to be little different than
when the air is at normal temperature. That
a long-enduring glow can be obtained at the
low temperature of liquid air and a pressure
approximately one tenth of one millimeter is
obviously important in its bearing on problems
of astrophysics.

THE AMERICAN CHEMICAL SOCIETY.
NEW YORK SECTION.
Tue eighth regular meeting of the New
York Section of the American Chemical So-
ciety was held at the Chemists’ Club, 108 West
55th St., Friday, May 5, at 8:15 p.m. The
chairman, Dr. Wm. J. Schieffelin, presided.
The program of the evening was as follows:
An Improved Form of Viscosimeter for the
Testing of Oils: Dante D. Jackson.
SCIENCE. 919
The earlier forms of instruments for the
determination of the viscosity of oils con-
sisted of bottles or bulbs which delivered a cer-
tain quantity of oil through an orifice of defi-
nite size. The necessity for jacketing such
instruments soon became evident, and various
methods were employed for this purpose. In
only a few cases, however, has any attempt
been made to protect the orifice so that a uni-
form temperature at this point would be as-
sured, and in the cases where the orifice has
been protected the oil under examination has
been allowed to flow into a vessel which was
outside the instrument. This causes a fall in
temperature from the beginning to the end of
the operation which is very considerable. A
form of apparatus designed by the author for
the testing of the viscosity of oil at 70° F.
(21.1° C.) and 212° F. (100° C.) is so arranged
that both the orifice and the oils under exami-
nation are kept at an exactly uniform tempera-
ture throughout the entire operation, and two
very considerable errors in the results are
thereby eliminated.
Condensation of Succinylosuccinic Ester with
Guanidine: A. W. Dox and M. T. Bogert.
Various attempts were made by the writers
to produce a naphttetrazine of the following
structure:

The well-known quinazoline syntheses when
applied to p-diaminoterephthalic acid, in
which the anthanilie acid grouping is present
on both sides of the nucleus, should give such
a compound. But diaminoterephthalic acid
proved to be very inert, and no condensations
could be made with it. It was found, how-
ever, that succinylosuccinic ester and guani-
dine condensed to a derivative of the above
naphttetrazine. The method of preparation
and subsequent analyses showed the product
to be 2, 6-diimino- 4, 8-dioxy-hexahydro- 1,
3, 5, 7-naphttetrazine. There is a possibility
also that the compound exists in the tanto-
meric form, having two amino instead of
imino groups. The substance is soluble
920
only in caustic alkalies and strong mineral
acids. From sodium hydrate it erystallizes
as a di-sodium salt in beautiful yellow needles
with green fluorescence. On the other hand,
a sulphurie acid salt can be obtained in color-
less rhombohedra by diluting the sulphuric
acid solution with water.
Synthesis of Quinazolines from 6 Nitro-acet-
anthranil: H. A. Sem and M. T. Bogert.
The 6 nitro-acet-anthranil was prepared by
the action of acetic anhydride on acetanthra-
nilic acid. It is much more reactive than
the acetanthranil. It combines at once with
primary amines forming first, the acid amide
by direct addition, and then by loss of water
passing over to the quinazolines.

The 6 nitro-acetanthranil is treated with an
excess of the amine in a water solution of
1 to 3. It is brought to boiling and the ex-
cess of amine is distilled off. The solution
is then made acid with acetic acid and filtered.
The quinazoline thus obtained is purified by
erystallization from alcohol.
The derivatives prepared are the methyl,
ethyl, normal propyl, iso propyl, secondary
butyl, iso butyl, iso amyl and allyl substitu-
tions of the (2)methyl (5)nitro- (4)ketodihy-
droquinazoline. These are all white erystal-
line solids of high melting points; soluble in
hot alcohol, slightly soluble in cold; soluble
in dilute acetic acid (from which they can
not be erystallized) and practically insoluble
in water.

tion of antimony sulphide by sulphuretted
hydrogen. The influence was studied quan-
titatively and it was found that the influence
was not directly proportionate to the masses
of acid present, a limit being reached in each
case, although the ratio of acid to the anti-
mony present was inordinately large. The
maximum effect obtained was for citric acid,
which retains, in solution, seventy per cent.
of the antimony present.
Of the acids studied, ethyl tartaric came
next, then malic, while tartaric was the least
energetic. The effect seemed confined to the
oxy-acids, because succinic acid is without any
effect and the influence of the citric acid is
entirely lost when its hydroxyl group has been
acetylated.
The Crystallization of Sodium Iodide from
Alcohols: Morris Logs.
It was accidentally observed that sodium
iodide is extremely soluble in methyl alcohol
and was not precipitated, even on the addi-
tion of considerable volumes of anhydrous
ethyl ether. The alcohol solution, on cooling
to room temperature, separates out crystals in
long shining plates. Below 0° a voluminous
mass of fine needles separates out, which are
identical in composition, but different in ap-
pearance from those just mentioned. Melting
point, 22 to 23°. Formula, NaI.3CH,0O.
Under similar circumstances, ethyl alcohol
dissolves the salt and erystallizes with it in
proportion, NalI.C,H,O, while propyl alcohol
yields 5Nal.8C,H,O. F. H. Poues,

THE TORREY BOTANICAL CLUB.
A MEETING of the club was held at the mu-
seum of the New York Botanical Garden on
Wednesday afternoon, April 26, 1905, with
seventeen persons present and President Rusby
in the chair.
The announced paper by Dr. P. A. Ryd-
berg on ‘The Composition of the Rocky
Mountain Flora’ was omitted by reason of —
the absence of the author.
‘Notes on the Wire-Grass Country of
Georgia’ was the title of the paper presented
by Mr. R. M. Harper.
CC — ———————
JUNE 16, 1905.]
The wire-grass country takes its name from
the wire-grass, Aristida stricta, which is com-
mon all over it. In a broad sense, the wire-
grass country coincides with the pine-barrens,
which constitute about two-thirds of the coast-
al plain of Georgia, but for the present pur-
poses the term is restricted to the Altamaha
Grit region, an area of about 11,000 square
miles.
The climate of the region, as compared with
New York City, is about 18° warmer in winter
and 9° warmer in summer. The rainfall
averages about fifty inches a year, and most
of it falls in the growing season. The geo-
graphical conditions are remarkably uniform
throughout, and on account of this uniformity
the flora is not very rich, only about one half
as many species being known there as in the
state of New Jersey, though the area is larger.
The region is naturally forested through-
out, but the forests are mainly of long-leaf
pine, which gives little shade. Consequently,
the most striking feature of the vegetation as
a whole is the adaptation to sunlight, usually
manifested by reduction of leaf-surface.
The plants of the wire-grass country can be
classified according to habitat into fifteen or
twenty groups. The principal habitats are
rock outcrops (constituting perhaps about one
one-hundredth of one per cent. of the area),
pine-barrens (over half the area), swamps,
ponds, sand-hills, hummocks and bluffs, some
of these with several subdivisions.
Civilization has influenced the flora prin-
cipally through agriculture, lumbering, tur-
pentining and fires. Only a small proportion
of the land may be said to be under cultiva-
tion. Lumbering has little effect on the her-
baceous flora, for the removal of the pine trees
does not appreciably diminish the amount of
shade. The turpentine operators have been
practically all over that part of the country,
and have done great damage to the forests.
Fires sweep over most of the region every
spring, being set purposely by stock-raisers to
burn off the dead grass, but the fires do little
damage where lumbering and turpentining
operations have not been carried on.
The known flora of the Altamaha Grit re-
‘tina, Taxodium imbricarium, Aristida stricta
SCIENCE. 921
gion consists of about 725 native species of
flowering plants, 75 weeds, 20 pteridophytes
and 60 bryophytes and thallophytes. The
lower cryptogams have been little studied.
The largest families are Composite, 100 spe-
cies; Cyperacee, 83; Graminer, 68; Legu-
minose, 50; Serophulariacex, 30.
Some of the commonest species of the re-
gion are Pinus palustris, P. Elliottii, P. sero-
Serenoa serrulata, Eriocaulon decangulare,
Quercus Catesbaei, Eriogonum tomentosum,
Magnolia Virginiana, Sarracenia flava, S.
minor, Kuhnistera pinnata, Cliftonia mono-
phylla, Nyssa biflora, N. Ogeche, Oxypolis
filiformis and Pinckneya pubens.
The following species are common in the
wire-grass country (each being known from
at least three counties), but are seemingly
confined to Georgia: Sporobolus (a species
with terete leaves), Rhynchospora solitaria
Harper, Hriocaulon lineare Small, Polygonella
Croomu Chapm., Siphonychia pauciflora
Small, Viola denticulosa Pollard (with leaves
a foot and a half long), Dicerandra odoratis-
sima Harper, Pentstemon dissectus Ell., Bald-
wina atropurpurea Harper, Marshallia ra-
mosa Beadle & Boynton and Mesadenia sp.
(near lanceolata).
One of the most interesting features of the
pine-barren flora, not generally known to
botanists, is that the whole region was sub-
merged beneath the sea in Pleistocene times,
consequently the species now confined to the
pine-barrens (from New Jersey to Texas),
perhaps several hundred in number, have
probably originated since that time.
Mr. Harper’s remarks were illustrated by
many photographs and specimens. The paper
was discussed by Drs. Britton and Rusby.
Mrs. Britton then spoke of certain interest-
ing southern mosses, especially of Hrpodium,
a curious genus having the habit of a Frul-
lania or Lejeunea. A species of this collected
many years ago by Sullivant at Augusta, Ga.,
was published by Austin as a hepatic under
the name Lejeunea biseriata. Mrs. Britton
discussed and exhibited also numerous mosses
from the extreme southern part of Florida.
922 SCIENCE.
A few of these appear to be undescribed, but
most of them are of species that are widely
distributed in the West Indian region.
Dr. Rusby showed specimens of spurious
ipecae roots which have found their way into
the markets. The true ipecac (from Ceph-
aélis Ipecacuanha of the family Rubiacer)
is now hard to obtain and high-priced. Some
of the spurious root comes from other species
ot the same genus, but the most common .
adulterant is from the genus Jonidium (Cal-
ceolaria) of the family Violacee. Dr. Rusby
exhibited also specimens of Porteranthus
stipulatus, which is sometimes called the
North American ipecac.
Dr. Britton showed living plants of two
species of Crassulacee which had come into
flower in the greenhouses of the New York
Botanical Garden. One was Sedum Nevii,
hitherto described from dried material, a spe-
cies collected originally in southwestern Vir-
ginia, but since found to extend to Indiana.
The other was a Pachyphytum from Mexico.
Dr. Britton stated that in North America,
north of the Isthmus, 284 species of Crassula-
cee may be recognized, distributed in 25
genera. Representatives of all these genera
have now been studied in the living state.

DISCUSSION AND CORRESPONDENCE.
THE METRIC ERROR.
To tue Eprror or Scrence: In your issue of
March 24, Mr. Henry B. Hedrick, of the
United States Naval Observatory, Washing-
ton, D. C., shifts from one metric fallacy to
another. The regulation school children fal-
lacy, as illustrated by the Hon. James H.
Southard, chairman of the Committee on
Coinage, Weights and Measures, in his report
to the House of Representatives in 1902, and
by Lord Belhaven in discussing a compulsory
metric bill in the House of Lords on February
23, 1904, is that the adoption of the metric
system will shorten the school life of every
child, including all branches of study, from
two thirds to three years; in other words, that
the eight years will be cut down to seven and
[N.S. Von. XXTI. No. 546.
one third or even to five years. It is on this
basis that Mr. Southard estimates a saving of
$1,000,000,000 in every generation. It is
clearly impossible to save by the adoption of
the decimal system any of the time occupied
by the study of non-mathematical branches,
such as physical training, penmanship, lan-
guages, geography, history, nature study,
drawing, cooking, sewing or music. ‘The say-
ing must be made in the time devoted to the
study of compound numbers, weights and
measures, which occupy 20 per cent. of the
school arithmetic. Applying this rate, 20 per
cent., to the 344 weeks occupied during the
eight years by all branches of mathematics,
we find 6.8 weeks to be so consumed. ‘This
estimate is not only fair, but extremely liberal
to the metric system. It is based on the eight-
year schedule adopted for the public schools
of New York City. The weekly time of 1,500
minutes is apportioned among the different
branches, and the uncertain amount of time
devoted to study outside of school hours is not
included. Thus there is no confusion of
schedule weeks with regular weeks. The case
is simple. This metric fallacy is the claim
that from two thirds to three years of the en-
tire school life can be saved by the adoption
of the metric system of weights and measures ;
when in fact, less than seven weeks is now
devoted to compound numbers, weights and
measures.
Turning from this old fallacy, let us con-
sider the new one formulated by Mr. Hedrick
to the effect that the adoption of the metric
system would save ten per cent. of the time
devoted to mathematics, or about two thirds of
what ‘may be called a mathematical year of
school life. In other words, that ‘the pupil
would be about a year ahead in mathematics
at the end of the eight years if he had only the
decimal system to learn.’
In exposing this new fallacy it is unneces-
sary to dwell on the fact that the study of
weights and measures in the school is merely
very superficial memorizing and that the real
knowledge of weights and measures is ac-
quired outside of the school by using them;
nor on the fact that the 343 weeks covers
~~

geometry and algebra, from which the special
study of weights and measures is excluded.
We can ignore these considerations because
the fallacy of Mr. Hedrick’s claim is due
chiefly to his assumption that the use and
study of fractions can be restricted to deci-
mals. That is impossible because the uni-
verse is not built that way. To save time by
abolishing the study of vulgar fractions is to
promote ignorance, not knowledge. Such a
policy of saving, carried to its legitimate con-
clusion, would do away with all study and
award diplomas for what the graduate from
the school of ignorance does not know.
The earth, from which the French scientists
a century ago thought they had derived the
meter, persists in revolving on its axis
365 29928 times during one revolution around
the sun. Everything from the chemical com-
binations of the elements to the arrangement
of the planets and fixed stars proclaims the
eternal verity which John Quincy Adams thus
expressed to Congress in 1821:
Decimal arithmetic is a contrivance of man for
computing numbers, and not a property of time,
space, or matter. Nature has no partialities for
the number ten, and the attempt to shackle her
freedom with them will forever prove abortive.
It seems like a waste of time to demonstrate
this self-evident proposition, but as many, in-
cluding the House of Lords and the chairman
of the Committee on Coinage, Weights and
Measures of the House of Representatives,
have reached the opposite conclusion, it may
be worth while to ask them to examine a
French arithmetic. Take that excellent work
by Joseph Garnier, ‘Traité complet d’arith-
métrique théorique et appliqueé au commerce,
a la banque, aux finance et a l’industrie.’ The
fifth edition (1900) contains not merely a few
incidental references, but many comprehensive
chapters dealing with vulgar fractions. Here
are a few chapter headings: ‘ Numeration et
propriétés des fractions ordinaires,’ ‘ Reduction
des fractions au méme denominateur,’ ‘ Simpli-
fication des fractions ordinaires,’ ‘ Conversion
d’un numbre entier, et d’une expression frac-
tionnaire,’ ‘ Addition des fractions ordinaires,’
‘Soustraction des fractions ordinaires,’ ‘ Mul-
tiplication des fractions ordinaires,’ ‘ Division

923
ordinaires, ‘Conversion des
fractions ordinaires en fractions décimales et
réciproquement,’ ‘ Fractions décimales period-
iques,’ ‘ Question sur les partages proportion-
nels, sur les mélanges.’
If these titles are not sufficient the metric
advocate in English-speaking countries can
be convinced by reading the French arithmetic
and studying its problems. It includes 43
pages on the metric system; 12 pages on old
pre-revolutionary weights and measures; 13
pages on the comparison of the old measures
with the new; 22 pages on compound num-
bers; and 86 pages on vulgar fractions.
The chapter on the metric system, entitled:
‘Poids et Mesures—Nouvelles Mesures au
Systéme Métrique,’ effectually dispels the
illusion that the metric system in its entirety
is simple. The system is explained there, not
to make converts to the metric cause, but for
practical application to every-day work. The
metric system in the French arithmetic with
its foreign nomenclature and combination of
decimal with binary divisions, such as hecto-
litre, demi-hectolitre, double decalitre, deca-
litre, demi-decalitre, double-litre, litre, demi-
litre, double decilitre, decilitre, demi-decilitre,
double centilitre and centilitre, is the very
uniformity of confusion. There are the same
complex vulgar fractions and weird problems
that one finds in all school arithmetics, only
in the French form perhaps a little more
weird. And all this in France more than a
hundred years after the following decree was
issued by Robespierre:
Decree of August 1, 1793.
Art. 1. The new system of weights and meas-
ures founded on the measurement of the earth’s
meridian and the decimal division will be used
throughout the Republic.
des fractions
In the face of such evidence, what is left
of the claim that the metric system will save
two thirds of a year or two thirds of a minute
in the study of mathematics in school?
That the teaching of the metric system in
American schools at the present time is but
a pretense can be proved by asking any grad-
uate a few simple questions. The fact is, that
the introduction of the metric system into
English-speaking countries, instead of making
924 SCIENCE.
the edueation of the child easier, will make it
vastly more difficult, because it will then be
necessary to teach the old system, which will
persist in use, and also to teach in fact as well
as in name the metric system with the con-
fusing ratios, direct and reciprocal, between
the English and metric units.
If any one wants proof of this he can find it
in the same French arithmetic. One chapter,
‘Nomenclature des anciennes mesures et com-
parison avec les nouvelles,’ treats of old units,
a few of which are: towse, pouce, ligne, aune,
pas, lieue, perche, arpent, solive, corde, setier,
muid, mine, minot, livre, once, denier, grain.
If he still doubts let him go to some great
French industry, textile manufacturing for
example, and there study the chaos of weights
and measures, thus described in 1902 by Paul
Lamoitier, a French manufacturer:
We are as much in the anarchy of weights and
measures for the textile industry as at the time
of the Revolution. * * *
The famous aune, do you know its equivalent?
Exactly 3 feet, 7 inches, 10 lines, and 10 points,
er in other words, 1.188447 meters; the foot being
equal to .324839 meter and divided into 12 inches,
the inch into 12 lines and the line into 12 points.
You would not imagine this as you are in the
habit of calling it 1.19 meters. You laugh! It
is, however, no laughing matter, unless you con-
sider it as I do, profoundly ridiculous. * * *
I will take my oath that the manufacturer of
Rouen if he has not studied each section sepa-
rately, has no idea what is the standard of Reims
or the denier of Lyons or Milan. And on the
other hand the manufacturers of Reims and Lyons
are likewise puzzled in making comparisons of the
diverse numberings of the diverse materials.
Such is the condition of French weights and
measures at the present time. The evidence
here presented is from French sources and
makes ridiculous not only the claim of say-
ing in education, but the whole metric proposi-
tion as well. This school children fallacy is
confined to English-speaking countries where
in the absence of experience with the metric
system the imagination supplies the founda-
tion for argument. The French labor under
no such delusion.
Of course, if they insist, English-speaking
countries can learn about the metric system

WILL THE METRIC SYSTEM SAVE TIME IN
EDUCATION 4
In the article entitled, ‘The Metric Fallacy,’
Science, March 3, p. 353, is the statement that,
in the New York public schools: ‘The time
allotted for all branches of mathematics
amounts to 341 weeks for the eight years.’
These figures relate to the actual time spent
in recitation, which extends through nearly
one year of school life, that is, about one
eighth of the entire time. A complete educa-
tion, to which Lord Kelvin referred in the
British Parliament, includes high school and
college, eight years more, which, with the same
division of time, gives two years of solid
mathematics. In England, one sixth, instead
of one eighth is given to mathematics, and it
is not extravagant to say that one half of this
is wasted because of our barbarous weights
and measures. Part of the economy of time
shown in this country is due to our decimal
money, part to the disuse here of many of the
old English measures still taught in the Eng-
lish schools, and part to the greater use here of
the metric system in our higher education, or
perhaps it would be more correct to say, the
non use therein of the English system.

scribed by several observers as consisting of
two parts: a ‘dome,’ and a ‘ spine’ or ‘ obelisk.’
The former was a dome-shaped elevation de-
veloped within the crater, which occupied a
large portion and in fact nearly the whole of
its interior and overtopped its rim. It was
situated directly over the voleano’s conduit,
and numerous explosions occurred in its sum-
mit portion. The latter, 7. e., the ‘ obelisk,’
was situated on one side of the dome and rose
as a mighty tower to a height of more than a
thousand feet above it. While the two struc-
tures just referred to have been described as
distinct, perhaps in part for convenience in
recording observations, there seem to be good
reasons, as will be stated below, for consider-
ing them as parts of the same massive-solid
extrusion or, as termed by some writers,
“eumulo eruption.’
In explanation of the upheaval of a mighty
spire or obelisk of rigid rock from within the
crater of Mont Pelé, two hypotheses have been
offered. The obelisk has been considered by
several geologists as the freshly congealed and
rigid summit portion of a column of molten
rock or magma, which was forced out of its
conduit in a massive-solid condition.

occasion.
The Scottish Geographical Maguzine states
that an expedition has recently started with
the object of thoroughly investigating the
oceanography and ‘biology of the region be-
tween India and Madagascar. The vessel
employed is H.M.S. Skylark, under the com-
mand of Captain Boyd Somerville, who is
accompanied by two civilian men of science,
Mr. Stanley Gardiner and Mr. Forster Cooper,
both of whom have already been engaged in
scientific work in the area under investigation.
The Skylark is to go first to the Chagos Archi-
pelago, then to Mauritius, which it is expected
will be reached about August 1. The voyage
will then be continued via the Cargados reef
to the Seychelles, whence the return will be
made to Colombo, the starting-point. Messrs.
Gardiner and Cooper are to be left at the
Seychelles, where they hope to spend some
months in scientific work, returning home in
January, 1906.
It is stated in Nature that at the forty-
second general meeting of the Institution of
Mining Engineers, held in London on June 2
and 3, several interesting papers were read.
Mr. T. Y. Greener dealt with the firing of
boilers by waste heat from coke ovens. Mr.
M. R. Kirby deseribed the compound winding
engine at Lumpsey iron mine. Its steam
consumption is only 38 pounds to 40 pounds
per indicated horse-power hour. Mr. F. Hird
gave the results of tests of the electric wind-
ing engine at Friedrichshall, and Mr. E. Lozé
deseribed electric winding engines installed
at French collieries. Mining education in
the United States was discussed by Professor
H. Eckfeldt, and in New Zealand by Professor
J. Park. Coal mining in India was dealt
with by Mr. T. Adamson. Mr. J. Jeffries
described the occurrence of underground fires
at the Greta colliery, New South Wales. Mr.
W. C. Blackett and Mr. R. G. Ware described
a striking innovation in mining practise, the
use of electrically driven mechanical convey-
ors for filling at the coal-face. Two years’
experience has shown a saving of 48 per cent.
over the ordinary pick and shovel method.
968
Lastly, Mr. A. R. Sawyer gave an account of
the geology of Chunies Poort, Zoutpansberg,
Transvaal. Incidentally, he mentioned some
old copper workings where native copper oc-
curs in some abundance in dolomite.
Tue Naturwissenschaftliche Verein at
Karlsruhe has, thanks to a considerable legacy,
been placed in a position to establish two
new stations for seismic observations, the one
in an underground passage at Turmberg, near
Durlach, the other in Freiburg.
Tue London Times states that a large com-
pany assembled in the Oxford University
Museum on May 31 at the annual conver-
sazione of the Junior Scientific Club. An
attractive program had been arranged. Pro-
fessor E. B. Poulton, F.R.S., delivered a lec-
ture on ‘Some Recent Work on Protective
Resemblance and Mimicry in Insects, and
Dr. A. E. Tutton displayed some of his latest
lantern slides of Alpine scenery. There were
demonstrations of the properties of radium
and spinning tops, experiments on color, and
an exhibition of thermit and high tempera-
tures, which included the making of artificial
diamonds. Messrs. Zeiss exhibited their in-
strument for seeing ultra-microscopic par-
.ticles, and there was a working installation of
wireless telegraphy. The Pitt-Rivers Mu-
seum was thrown open, and music was pro-
vided by the band of the Grenadier Guards.
Nature says that under the name of the
‘Potentia Organization,’ an international asso-
ciation has been formed with the object of
establishing among nations a mutual relation-
ship and cooperation for the diffusion of ac-
curate information and unbiased opinion con-
cerning international events and movements,
and to combat narrow, prejudiced, and often
interested views and news that contribute so
much to international mistrust and misunder-
standing. It is proposed to publish through-
out the world, through the medium of news-
papers and reviews, statements of simp‘e fact
and expressions of opinion by eminent public
men of all nations on all important political,
social, philosophical, economic, scientific and
artistic questions, to present the sincere views
of experts on all current international events,

MASSACHUSETTS INSTITUTE OF
TECHNOLOGY AND HARVARD
UNIVERSITY.
THE
THE proposed affiliation or alliance of
the Massachusetts Institute of Technology
with Harvard University was, as we have
already reported, approved at a meeting
of the corporation of the institute on June
9. Thirty-two of the forty-seven members
of the corporation were present, and by a
vote of 20 to 12 it was agreed to accept
the terms of the agreement drawn up by
the committee of the two institutions.
Before the agreement can become effective
the corporation and overseers of Harvard
University must take action and several
legal questions must be passed upon by the
courts. It will be remembered that on
May 5 the faculty of the institute adopted
by a vote of 56 to 7 the report of the com-
mittee adverse to the affiliation. A full
account of the report adopted by the fac-
ulty and of the minority report, together
with an account of the meeting of the
alumni on May 4 has been published in a
special issue of The Technology Review.
In view of the great importance of the
proposed merger for university develop-
ment and technological education we re-
produce here: (1) The agreement pre-
pared by President H. S.. Pritchett and
Professor A. Lawrence Lowell on behalf of
the institute and Dr. H. P. Walcott and
Charles Francis Adams, 2d, Esq., on behalf
of the university, now adopted by the cor-
poration of the institute; (2) the will of
the late Gordon McKay in so far as it re-
lates to his bequest to Harvard University,

to the alliance adopted by the faculty of
the institute and extracts from the minority
report.
AGREEMENT BETWEEN HARVARD UNIVERSITY
AND THE MASSACHUSETTS INSTITUTE
OF TECHNOLOGY.
Harvard University and the Massachu-
setts Institute of Technology, being con-
vineed, after a careful consideration of the
conditions which affect the work of educa-
tion in industrial science, that such work
can be greatly advanced and enlarged by
a cooperation of the two institutions, in
order to secure mutual assistance, render
possible a larger enterprise, promote econ-
omy, avoid duplication and competition,
and give to the purpose of donors who have
bestowed money in trust for that object a
fuller accomplishment, do make this agree-
ment, which shall endure so long as it shall
be found to serve, to the satisfaction of
both institutions, the objects above de-
elared. But, whereas the carrying out of
such agreement will require the employ-
ment of the income of the funds which the
University holds, or will hereafter hold in
trust, and the University feels that faith-
fulness in the performance of these trusts
which it has accepted is its first duty, to
which all other considerations must yield,
this agreement shall not go into effect until
and unless the University shall have ap-
plied to the Supreme Judicial Court for
instructions and the court shall have made
a decree that this agreement may be carried
out without violation of its duties as a
trustee and in accordance with law and
equity.
I.
The organization of the University, the
organization of the Institute, and the title
of each to its property and funds shall re-
main unaffected by this agreement, as shall
also the rights and duties of each in invest-
ing and managing its funds.
i i
The institution for the combined work of
promoting and furnishing education in in-
dustrial science, which it is the object of
this agreement to establish, shall retain the
name of the Massachusetts Institute of
Technology ; it shall be under the direction
of an Executive Committee, and the in-
struction therein shall be given by a Fac-
ulty, which two bodies shall be constituted
as herein below provided.
Lau
The said Executive Committee shall con-
sist of nine persons, to be designated by
the Massachusetts Institute of Technology,
of whom two shall be the President of the
Corporation of the Institute and the Treas-
urer of the Institute, and three shall be
members of the Corporation of the Uni-
versity.
Subject to the restrictions herein below
expressed, the said Executive Committee
shall have the general administration and
superintendence of all matters concerning
said combined work, including the appoint-
ment of officers of instruction and govern-
ment, and of servants, the power to remove
any of them, the fixing of their salaries and
the prescribing of their duties, the care of
buildings, property, and equipment, the
appropriation of money put at its disposal
under this agreement, the fixing, collecting,
and expending of students’ fees, and the
supervision and direction of the work of
the Faculty, these being substantially the
powers now conferred on the Executive
Committee of the Institute by its by-laws;
it being, however, expressly provided that
all appropriations from money furnished
either by the University or by the Institute,
and all proposed appointments or removals
of officers whose salaries are to be paid
[N.S. Vou. XXI. No. 548.
JUNE 30, 1905.]
therefrom, shall be submitted to the Cor-
poration concerned and approved by it be-
fore being finally adopted, it being under-
stood that students’ fees shall be deemed
to be furnished by the Institute, and that
no change shall be made in those fees with-
out its approval.
The said Executive Committee shall keep
records of its proceedings, and shall make
reports to the Corporation of the Univer-
sity and the Corporation of the Institute
annually, and at such other times as either
Corporation may request.
LV.
The President of the Institute for the
time being shall be the President of the
said Executive Committee, and shall pre-
side at its meetings, when present. His
salary, as fixed by the Corporation of the
Institute, shall be paid from the funds fur-
nished by the Institute. He shall be the
Chairman of the Faculty, shall have the
superintendence of the several depart-
ments, and shall act as general executive
and administrative officer, subject to the
direction and control of said Executive
Committee. He shall annually make a re-
port to the Corporation of the University
and to the Corporation of the Institute.
Whenever a person shall vacate the office
of President of the Institute, he shall there-
upon cease to be a member of the said
Executive Committee.
iV:
The Treasurer of the Massachusetts In-
stitute of Technology shall be ex officio the
Treasurer of the said Executive Committee.
He shall, as Treasurer of the said Execu-
tive Committee, have charge of the funds
put at the disposal of said committee, shall
make such payments as the committee may
authorize, shall keep accurate accounts of
all money received and expended, and shall
make report of his doings annually, or
oftener if required, to the said committee,
SCIENCE.

and to the Corporation of the University
and to the Corporation of the Institute.
VI.
The Faculty shall consist of all the pres-
ent professors, associate professors, and as-
sistant professors of the Institute, and all
professors, associate professors, and assist-
ant professors of the University who now
give courses of instruction leading to de-
grees in industrial science, and such officers
hereafter appointed as said Executive Com-
mittee may designate. The present pro-
fessors, associate professors, and assistant
professors of the University as aforesaid
shall not be removed nor. have their present
salaries reduced without the consent of the
Corporation of the University.
Subject to the supervision and direction
of the said Executive Committee the Fac-
ulty shall have charge of instruction and
discipline.
Var.
Subject to the reservations hereinafter
set forth the University shall place at the
disposal of said Executive Committee, as
above provided, the net income of all funds
which are now credited on its books to the
eredit of the Lawrence Scientific School,
also the use of all machinery, instruments,
and equipment which the University holds,
and the income of all property which it
may hereafter acquire for the promotion of
instruction in industrial science, and also
three fifths, but no more, of the net income
which may accrue from the bequest and
devise of the late Gordon McKay.
Wen:
Subject to the reservations herein set
forth, the Institute shall place at the dis-
posal of the said Executive Committee the
net income of all funds and the use of all
property and equipment which the Insti-
tute may hold for the promotion of instruc-
tion in industrial science, reserving only

such amounts and property as it may re-
quire to maintain its organization and to
carry on such functions as may remain to
it independently of the promotion of indus-
trial science.
Dx
In so far as money contributed by either
Corporation under this agreement may be
used by the said Executive Committee for
the purchase of equipment or supplies, the

title thereto shall be in the Corporation
whose money is appropriated therefor.
xe
The site of the institution shall be in
Boston on the right bank of the Charles
River, as nearly as practicable opposite to
Harvard Square, and the Massachusetts
Institute of Technology shall there erect,
furnish, and equip buildings having the
capacity of at least its present buildings.
But the Institute shall not be required to
proceed with such purchase and construc-
tion until it shall have sold a sufficient part
of the land which it now owns. Provided,
however, that this agreement shall be
avoided if at the end of four years from
the time when this agreement goes into
effect the Institute shall not have purchased
said land and proceeded to a substantial
extent with such construction.
Das
Within three years after the Massachu-
setts Institute of Technology begins the
construction of such new buildings, if the
Institute is then prepared to give in its
new location to the students of the Lawr-
ence Scientific School all needed instruc-
tion in industrial science, the Lawrence
Scientific School shall be discontinued as
a separate school of industrial science so
long as this agreement remains in force.
DOT,
The degrees of Bachelor, Master and
Doctor in Science, so far as given in indus-
trial science, and all degrees in engineer-
ing, together with the requirements of
courses of study leading to these degrees,
shall be within the province of the Fac-
ulty; and these degrees shall be conferred
by the Corporations of the University and
the Institute, acting separately.

Male students in the Institute shall have
the same privileges as students in Harvard

University in the use of the playgrounds,
museums, and libraries of the University.
Under regulations to be made by the two
Corporations, and on payment of proper
fees, students of the Institute shall be ad-
mitted to courses of instruction and the use
of laboratories of the University, outside of
those pertaining to industrial science, and
students of the University to the courses
and use of laboratories of the Institute.
XIV.
The Corporation and Overseers of the
University and the Corporation of the
Massachusetts Institute of Technology shall
each have full right at all times to inspect
the institution, and suggest to the said
Executive Committee changes in the meth-
ods of management.
XG
The Department of Architecture in the
University and in the Institute respectively
are not included in this agreement, but re-
main unaffected hereby.
XVI.
It is expressly provided that, as regards
the funds and property of the University
and of the Institute respectively, this
agreement shall be subject to any special
terms and requirements upon which such
funds and property may be held; and any
property or funds which may be held at
any time by either Corporation under such
terms and restrictions as would prevent the
use of them in the precise manner contem-
plated by this agreement shall, neverthe-
less, be used by the two Corporations re-
spectively for the support, benefit, or en-
couragement of the scheme agreed upon,
in such manner as may be permissible and
in accordance with the trusts upon which
they may be held.
XVII.
The arrangements established by this
agreement may be terminated at any time
974
either by the President and Fellows of
Harvard University or by the Corporation
of the Massachusetts Institute of Tech-
nology, upon reasonable notice to the other
Corporation.
In the event of the termination of this
agreement, the Massachusetts Institute of
Technology must pay, at such prices and
upon such terms as the parties may agree
upon, and, if they can not agree thereon,
as may be fixed by arbitration (usual arbi-
tration clause), for any buildings or fix-
tures upon said site, paid for with funds
furnished by the University.
XVIII.
This agreement shall take effect when
finally adopted and approved by the Cor-
poration and the Overseers of the Univer-
sity and the Corporation of the Institute,
and when and if a decree of the Supreme
Judicial Court, as provided for in the pre-
amble hereof, shall have been obtained.
EXTRACT FROM THE WILL AND CODICILS OF
THE LATE GORDON McKAY.
I direct that eighty per cent. of the bal-
ance of said net annual income, after pay-
ing the annuities (the remaining twenty
per cent. being held as a reserved fund to
cover any future possible deficiency in the
annual income to pay said annuities), shall
be safely invested by my trustees from time
to time until such accumulations amount to
the sum of one million dollars, and then I
direct my trustees to pay over said sum of
one million dollars to ‘the President and
Fellows of Harvard College in their cor-
porate capacity,’ if said Corporation shall
accept the same for the purposes and upon
the terms and conditions hereinafter set
forth, to be held and applied by them and
their successors in said capacity for the
purposes and trusts hereinafter declared.
I also direct said trustees to pay to the
said President and Fellows (if and after
SCIENCE.
[N.S. Vou. XXI. No. 548.
said sum of one million dollars has been
paid over to them, as aforesaid) annually
eighty per cent. of the balance of the net
income accruing from the remainder of my
estate after paying the existing annuities;
and upon and after the death of the last
surviving annuitant I direct said Trustees
to pay over to the said President and Fel-
lows of Harvard College all the residue of
my estate, including all unexpended in-
come, all of which said sums I give to the
said. President and Fellows of Harvard
College, provided they accept the same, as
aforesaid, strictly upon the trusts and pur-
poses following, namely :—
I direct, if the said Corporation, the
President, and Fellows of Harvard College
accept said gift, that the sum total of all
the property and moneys conveyed by my
trustees to the President and Fellows of
Harvard College shall be forever known
and described in the records of the Presi-
dent and Fellows and on the books of their
Treasurer as the Gordon McKay Endow-
ment.
I give the President and Fellows full
powers to hold, manage, and protect, im-
prove, sell, invest, and reinvest at their
discretion, from time to time, the property
in which this Endowment may at any time
be invested. I also give the said Corpora-
tion authority, in case the principal shall
be at any time impaired through misfor-
tune, to accumulate the income of the
Endowment, or any part thereof, until the
principal shall be made good; but, in order
that the principal and income may share in
the guaranty or insurance which is derived
from the large mass and wide distribution
of the University’s investments, I prefer
that the investments of the Endowment be
merged, as soon and as far as in the discre-
tion of the President and Fellows they
prudently and equitably may be, with the
general investments of the other permanent
funds held by the President and Fellows.
JUNE 30, 1905.]
The net income of said Endowment shall
be used to promote applied science :—
First. By maintaining professorships,
workshops, laboratories, and collections for
any or all of those scientific subjects which
have, or may hereafter have, applications
useful to man; and
Second. By aiding meritorious and
needy students in pursuing those subjects.
Inasmuch as a large part of my life has
been devoted to the study and invention
of machinery, I instruct the President and
Fellows to take special care that the great
subject of mechanical engineering in all its
branches, and in the most comprehensive
sense, be thoroughly provided for by my
Endowment.
I direct that the President and Fellows
be free to provide from the Endowment all
erades of instruction in applied science,
from the lowest to the highest, and that
the instruction provided be kept accessible
to pupils who have had no other oppor-
tunities of previous education than those
which the free public schools afford.
I direct that the salaries attached to the
professorships maintained from the En-
dowment be kept liberal, generation after
generation, according to the standards of
each successive generation, to the end that
these professorships may always be at-
tractive to able men, and that their effect
may be to raise, in some judicious measure,
the general scale of compensation for the
teachers of the University.
I direct that the professors supported
from this Endowment be provided with
suitable assistance in their several depart-
ments by the appointment of instructors of
lower grades and of draughtsmen, foremen,
mechanies, clerks, or assistants, as occasion
may require, my desire being that the pro-
fessors be free to devote themselves to
whatever part of the teaching requires the
greatest skill and largest experience and to
SCIENCE.
975
the advancement of their several subjects.
I direct that the President and Fellows
be free to erect buildings for the purpose
of this Endowment, and to purchase sites
for the same, but only from the income of
the Endowment.
I direct that all the equipment required
to illustrate teaching or to give students
opportunity to practise, whether instru-
ments, diagrams, tools, machines, or appa-
ratus, be always kept of the best design and
quality, so that no antiquated, superseded,
or unserviceable implement or machinery
shall ever be retained in the lecture-rooms,
workshops, or laboratories maintained from
the Endowment.
Finally, I request that the name Gordon
McKay be permanently attached to the pro-
fessorships, buildings, and scholarships, or
other aids for needy students which may
be established, erected, or maintained from
the income of this Endowment.
EXTRACTS FROM THE MINORITY REPORT IN
FAVOR OF THE ALLIANCE.*
I. If the plan is not adopted, Harvard
will be obliged to energetically develop the
Lawrence Scientific School as a broad col-
lege of applied science. With her ‘re-
sources, reputation, and large body of
alumni, and profiting by the lessons of
experience, there is no doubt that she can
make this school a success. This is abun-
dantly proved by the experience of other
universities which have technical schools.
This school will be a rival of the Institute
in the same community.
II. Competition in business or in educa-
tion always involves some economic waste.
In edueation it is beneficial only if neces-
sary to keep up the spur to endeavor. The
Institute does not require competition with
*This report was signed by Professors Fay,
Jaggar, McKibben, Moore, Swain, Walker, and
was supported by President Pritchett.
976
Harvard for this purpose, and without it
will have ample competition with the
rapidly growing schools of the Middle and
Western States.
III. Of two competing schools, either
one will be better than the other or they
will be different. If Harvard should build
up a great technical school, though ours
might on the whole be the better, Harvard
would undoubtedly draw to herself many
strong students. Every strong student
that we lose is a distinct disadvantage to
us. We should keep all the strong stu-
dents, if possible, and let the weak ones go
to other schools.
If Harvard should make the Lawrence
Scientific School a graduate school, as we
understand is desired by its Dean, would
not many of the strongest men who come
to Boston to study engineering prefer to go
where they would be associated solely with
more mature men, all having completed
their undergraduate courses and devoting
themselves entirely to professional work,
instead of coming to the Institute, where
they would be associated with younger
men, and with many special students, in an
undergraduate school?
IV. Technical education in this country
is scareely fifty years old. It is not yet
on the same plane with instruction in the
so-called learned professions. The time
has not yet come for making engineering
schools generally graduate schools, lke so
many of those of law and medicine. The
Institute and most other engineering
schools must remain primarily, for some
time at least, undergraduate schools; but
the level of industrial education will in the
course of time be gradually hfted. The
engineer, in order to reach the highest
standard, will be expected to be liberally
trained and yet to be a specialist. The
Institute being one of many, when the uni-
versity technical schools more generally

[N.S. Vou. XXT. No. 548.
reach the standard of the Institute,—and
some of them have already fully reached
and perhaps in some respects exceeded it,
—is there not ground for believing that
the young man who desires to qualify him-
self most completely for the engineering
profession will seek the school which has
the broadest environment, where he will be
brought into relations with students of
other professions ?
V. The Institute having shown the way,
there are now many technical schools where
forty years ago there were few. A great
majority of these are intimately connected
with universities, and the fees at many of
them are very low; they are doing excellent
work, some as good work as the Institute;
they have a much larger body of students;
and they are turning out each year a much
larger body of graduates than the isolated
technical schools. The influence of these
university technical schools, industrially
and educationally, is increasing relatively
in comparison with the isolated technical
schools. May not our own influence di-
minish in the course of time, as the body of
alumni of the university technical schools
increases in number and in influence?
Will we not gain by placing ourselves in
the main educational current in the coun-
try, by allying ourselves with our most
powerful university, especially as we can
do so without sacrificing our methods or
our control?
VI. Competition from the West will in-
erease. The industrial centre of the
country is shifting. When the Institute
was established, it was in New England;
and even the iron industry and the mining
industry were important here. As the
years go by, new technical schools will be
established in the West, at places like Chi-
eago and Pittsburg, either independent or
connected with universities. These schools
may well be in closer touch with the indus-
Junu 30, 1905.]
tries of the country than any school in New
England would be. When they shall have
had time to grow to their full development,
what will be the effect upon the Institute
of Technology, especially if it is isolated,
out of the main current of educational de-
velopment, and actively competing for sup-
port and students with another strong
school not three miles distant?
VII. If this agreement is rejected by the
Institute Corporation and Harvard ener-
getically develops her technical school,
Harvard alumni all over the country—
lawyers, bankers, merchants, engineers,
men in responsible positions in the great. in-
dustries—will be enlisted in an active cam-
paign to promote Harvard interests as
against Institute interests. By acting to-
gether and giving the preference to Har-
vard graduates, they may at least seriously
hamper the growth and retard the develop-
ment of the Institute. By allying our-
selves with Harvard, we should gain the
active support of this large and influential
body of men instead of their opposition.
VIII. By combination and cooperation
instead of competition there is economy in
administration; in heads of departments;
in libraries and photographs; in museums
and collections; in lecture apparatus and
similar appliances; in buildings, especially
as regards large lecture-rooms not often
used; and, to a greater or less extent, in
laboratory apparatus.
IX. There is also an economy or an in-
crease of efficiency in combination, with
reference to the instructing force. With
the same number of men that would be re-
quired for two separate institutions a
single institution would allow greater
specialization in the teaching, permitting
the student to come in contact with a larger
number of inspiring teachers, or it would
enable more than one teacher to teach the
same subject, thus stimulating each to do
SCIENCE.
977
his best. This stimulus would be greater
if the two teachers were in one institution
than if they were in two. There might,
and probably would, also be an economy
in the number of teachers, especially in
the purely lecture courses, and, as already
stated, in heads of departments.
X. If Harvard energetically develops
her technical school, she will probably, in
course of time, have more resources avail-
able than the Institute, considering her
large number of wealthy alumni and their
relations to the business world. The Me-
Kay will provides ‘‘that the salaries at-
tached to the professorships maintained
from the endowment be kept liberal, gen-
eration after generation, according to the
standard of each successive generation, to
the end that these professorships may
always be attractive to able men, and that
their effect may be to raise in some judi-
cious measure the general scale of compen-
sation for teachers of the university.’’ In
the course of time, therefore, when the
McKay money becomes entirely available,
it seems inevitable that Harvard will have
a very high standard of salaries for pro-
fessors in her technical school,—probably
much higher than those at the Institute. In
this ease she could attract to these positions
the ablest men, who ean not now afford to
be teachers because of the inadequate re-
ward. Whether under these conditions the
Institute would be the leader in technical
education in this community is at least
doubtful.
XI. Increase in the number of students,
if accompanied by corresponding adapta-
tion or organization of the teaching foree,
should also conduce to economy and effi-
ciency.
XII. Whether the plan is adopted or not,
we can limit our numbers by raising the
standard. If increase of numbers is a dis-
advantage, we should limit them in this
978
way rather than in any arbitrary way. By
adopting the proposed plan, we retain the
field, and can get all the strongest students
from this community. If there are two
schools, Harvard will very likely get as
many as we do.
XIII. The addition of the Harvard
Faculty to that of the Institute would be
a distinet. gain. Whether all would har-
moniously work together at once is of
little consequence. Temporary adjust-
ments might have to be made. With
broad-minded cooperation a larger effi-
ciency would result by adding to our body
a staff of able teachers with new ideas and
without Institute traditions, but animated
by ideals and purposes as high as our own.
Of all men the teacher is most likely to get
into a rut. In-breeding emphasizes this
tendency. The influx of a body of new
men with other points of view than our
own would tend to counteract it.
XIV. If the proposed plan should result
in more intimate association between our
Faculty and the Faculty of Harvard Col-
lege, the result would be beneficial.
XV. Institute students are given a nar-
row training, and would benefit by associa-
tion with men studying the humanities and
the other professions.
XVI. One great lack which Institute
men have always felt is college life and col-
lege spirit. Many of them come from
their homes or boarding places in the morn-
ing, attend their classes, and go home at
night, seeing little of their fellows, and
gaining no experience in the art of getting
on with men. Their after-success will
probably depend as much upon their abil-
ity to deal with men as upon a knowledge
of their profession, and their progress may
be much retarded by a lack of some
qualities which they might gain at the In-
stitute if they could take the time for more
intimate association with their classmates.
SCIENCE.
[N.S. Von. XXI. No. 548.
Moving to a site out of town would give
the opportunity for a change in this re-
spect, since it would render possible the
introduction of dormitory life.
XVII. The surroundings of many of our
Institute students in cheap _ boarding
houses, with poor food and the temptations
of a great city about them, are in many
eases most unfavorable. We believe the
distractions and diversions of such a life,
and even the distractions in home life from
the presence of friends and relatives and
from home chores and duties, are much
greater on the average than those which
would arise under proper management in
the dormitory system. The proposed plan
would be an. improvement over present con-
ditions, because a larger proportion of stu-
dents would live in the suburbs, and be-
cause dormitories might be established,
which is now impracticable.
XVIII. Educational institutions must
depend more and more upon gifts from
wealthy men. Harvard University and
the Institute are in the same community.
They must appeal for support to the same
class of persons, and in many eases to the
same individuals. If the two were work-
ing together, the finanical results would be
better than if the two were working sepa-
rately and in opposition to each other.
XIX. Rich men who have large sums of
money to give away desire to have their
gifts expended economieally, and, as a rule,
they believe that economy results from
combination and cooperation rather than
from competition. If this agreement
should be declined by the Institute, many
of them would say that the Institute was
unwilling to cooperate, and thereby in-
crease efficiency and economy, while Har-
vard University was willing to cooperate.
This attitude would render them less likely
to give to the Institute.
The present plan seems to offer almost
June 30, 1905.]
the ideal form of affiliation. The Institute
students, together with those now registered
in the Lawrence Scientific School, number
about 2,100; the Harvard College under-
graduates number about 2,000. The tech-
nieal school, therefore, would be the larg-
est part of the combination, and would be
subject to its own Faculty. It would seem
most improbable that under these circum-
stances the smaller body, the great ma-
jority of whom are also earnest men, could
unfavorably affect the larger and more
compact professional body.
XXI. The reciprocal privileges which
the plan proposes would very likely be of
great value to both institutions, partic-
ularly in the case of advanced students.
XXII. By the plan proposed we ean get
all the benefits of combination and coopera-
tion without relinquishing the power to do
anything we are able to do under present
conditions.
XXIII. The plan proposed would be of
advantage to Harvard for many of the
reasons which have already been adduced.
XXIV. The plan proposed would be of
benefit to the community by giving it on
the whole better advantages for technical
education than could be obtained in any
other way, and by enabling it to enthusi-
astically support, financially and morally,
a single great institution with which the
name of Boston and Massachusetts would
be everywhere associated.
Conclusion.
Weighing the arguments in favor of the
plan and those. against it, we believe that
those in favor decidedly outweigh those
against, and that the possibilities are
offered us of building up a better and a
greater Institute of Technology than has

University and to the community. Boston
would have one great technical school unit-
ing the forces of two great institutions,
and with a united community supporting
it. It may be anticipated that it would
not be allowed to suffer financially. The
Institute would be free, under the plan,
to develop in any way which might seem
best, and it could do anything under the
plan it can do at present, with the added
advantage of MHarvard’s support. We
could draw to us the strongest students not
only from this community, but from other
parts of the country, without suffering any
of the disadvantages which would arise, as
we believe, from the active competition of
a neighboring and powerful school. The
best way, and indeed the only way to ac-
complish in full measure the greatest fu-
ture for the Institute, would seem to us to
lie in securing control of the field of tech-
nical education in this community.
EXTRACTS FROM THE REPORT ADVERSE TO THE
ALLIANCE ADOPTED BY THE FACULTY.
In the list of advantages to the Institute
connected with the proposed agreement,
removal to the Brighton location has been
included by few. President Pritchett
does not view it with complete favor, and
opinions differ merely as to the degree of
disadvantage. Apart from the financial
question and the mandatory character of
the agreement in this respect, the proposed
site has disadvantages connected with the
housing and life of the students and the
problem of transportation.
At present 44 per cent. of our students
live at their own homes, with advantage
to themselves and to the Institute. Un-
doubtedly this has an important conserva-
tive effect in determining the atmosphere
of the Institute. Removal to a more dis-
tant site would greatly decrease this num-
ber, and increase the total cost of living
980 SCIENCE.
to the student body. . It would also intro-
duce the problem of establishing a dormi-
tory system—a problem altogether too im-
portant to be settled thus incidentally. A
carefully devised dormitory system, it is
true, might not seriously menace the pro-
fessional spirit of our students; but the
establishment of such a dormitory system
in proximity to Harvard College would in-
volve exceptional difficulties. Upon the
question of transportation it may be said
that the means now existing and projected,
together with the increased facilities that
a demand would stimulate, make the loca-
tion as accessible as might be expected of
any place at a similar distance from the
center of Boston.
On the other hand, our present site has
contributed in no small degree to the dis-
tinct individuality of the Institute. This
site, in a busy city, is by many regarded
as one of our most valuable educational
assets, and has great strategic advantages.
Students can live in any of the surround-
ing suburbs, and can in general reach the
Institute by one line of steam or electric
ears without change, and are within walk-
ing distance of the railroad stations; and
in like manner they can go from the Insti-
tute to engineering and industrial works in
a wide circle of suburbs and neighboring
towns. The central location attracts to
our halls educational and engineering
bodies that help to make a professional
atmosphere, and assist in advertising the
Institute to a scientific constituency of the
utmost importance.
Lack of Definition of the Term ‘Industrial
Science,’ as Bearing upon Instruction
and wpon Degrees.
In connection with the proposed alliance,
much has been said of the avoidance of
educational duplication; but the terms of
the agreement as they stand fail to make
[N.S. Vou. XXI. No. 548.
it clear that any definite partition has been
formulated, either in scientific instruction
or in the granting of degrees in science.
Nowhere is there a definition of the term
‘industrial science,’ upon the exact mean-
ing of which these matters depend. The
interpretations of the term which have
been given to us, in so far as they make
matters clear, imply that the intention is
to consent to continued duplication in large
elementary courses and in some advanced
classes, rather than to attempt the unsound
and impossible separation between pure
and applied science. It has been explained
to us that the intention is to continue in
the Institute both instruction and the
granting of degrees in such branches of
pure science as chemistry, physics, geology,
and biology. There is reason to believe
that the University contemplates the reten-
tion of instruction and degree-giving in all
these subjects, as well as the retention of
elementary instruction in at least some
branches of industrial science as College
electives. The University also reserves its
right to grant any and all degrees, in ap-
plied science as well as in pure science;
but the agreement implies that Harvard
degrees in applied science would hereafter
be granted only upon the recommendation
of the Faculty of the Institute. The Insti-
tute, on the other hand, seems to agree by
implication to discontinue the granting of
the Ph.D. degree, and of all degrees in
other than ‘industrial science,’ which, as
interpreted to us, is to inelude those
branches of pure science, already men-
tioned, in which degrees are at present
granted by the Institute. If, as would ap-
pear, the wording of Section XII. consti-
tutes an abdication on the part of the In-
stitute of the right to grant any degrees
other than those specified, why should such
an abdication be permissible on the part
of the Institute when, as we are informed,
JUNE 30, 1905.]
the lawyers doubted whether the Univer-
sity could legally divest itself of a similar
right?
Probability that the Earlier Years of In-
stitute Work would be Absorbed by
Harvard College.
Disaster to the integrity of the Insti-
tute’s curriculum will, it seems to us, be
the logical result of this lack of definition
of the term ‘industrial science,’ when it is
taken in connection with the fact that the
College gives, and is likely to continue giv-
ing, elementary courses in mathematics,
and in chemical, physical, and engineering
subjects. It will be much more natural
for a student intending to get an engineer-
ing degree to take his elementary work in
the College. That such a result is antici-
pated by the framers of the agreement
would appear from the statement of Presi-
dent Pritchett that the stronger technical
schools are to take a forward step by which
they will be free from much elementary
work.
Two special causes are likely to contri-
bute largely to this result. The first is
that the tuition fee at Harvard is $100 less
than that of the Institute. Even if the
fees were to be equalized, at a serious
financial loss to the Institute, there yet re-
mains the second fact that participation in
University athletics is open only to students
enrolled at Harvard. Boys who are in-
tending ultimately to become engineers,
but who are also ambitious of athletic dis-
tinction, or even those who desire the real
use rather than the partial privilege of
the Harvard playgrounds, would be lkely
to take their elementary work in the Col-
lege rather than in the Institute. Under
existing conditions many parents prefer
the professional atmosphere to’ the acad-
emic, and send their sons to the Institute
rather for that reason than because they

have any particular engineering career
definitely planned for them. It ean hardly
be expected that this patronage would con-
tinue under the altered conditions now pro-
posed.
Yet the most serious effect upon our cur-
riculum, in consequence of such a change of
methods, would be the loss of that absolute
control over our instruction which we con-
sider essential to the maintenance of our
standards. If we turn over our elemen-
tary scientific work to another faculty,
whose educational purposes and methods
are essentially different from ours, we
make impossible that close coordination of
studies which we consider a prerequisite
of suecessful technological education.
Courses of elementary instruction, actually
conducted by the Institute, not only give
us a rule of comparison between the scien-
tifie preparation that is offered by students
coming from other institutions and that
which we desire and can insist upon, but
they insure an advantageous uniformity
of training to the great bulk of our stu-
dents in those scientific studies which are
the fundamentals of all technological edu-
eation. We do not view any prospect of
their abandonment with favor.
Sacrifice of Control.
A further disadvantage of the proposed
agreement is the modification that it makes
in the present method of government of
the Institute. A new Executive Com-
mittee is created, of which at least three
members out of nine shall be members of
the Corporation of the University. It is
our opinion that under this arrangement
the ‘organization, control, and traditions’
of the Massachusetts Institute of Technol-
ogy would not be so safeguarded as to in-
spire that confidence in the preservation
of its individuality and in the continuance
of its educational autonomy which we re-
982 SCIENCE.
gard as absolutely essential to the well-
being of the Institute and to the efficiency
of iis, work? * * *
The Department of Architecture.
A thoroughly objectionable section of
the agreement is that which excludes the
Department of Architecture from its pro-
visions, leaving the future of one of the
original and one of the most brilliantly
successful departments of the Institute
wholly unsettled and problematical. * * *
Loss of Alumni Interest and Support.
Another disadvantage of the alliance is
the danger that the interest and support
of the graduates of the Institute will be
sacrificed. An important element in the
organic growth of an educational institu-
tion is a strong, well-organized association
of its alumni, the men who can best appre-
ciate the advantages and needs of the insti-
tution and who know the places where it
can be strengthened. The Institute has
such an Alumni Association, with local
branches in all parts of the United States,
and with a compact subsidiary organiza-
tion in the form of an Association of Class
Secretaries which has proved itself to be
useful and efficient, and which promises to
grow in importance. The alumni have
shown a deep and enthusiastic loyalty,
which has taken a practical form in sub-
scription for the William Barton Rogers
Scholarship Fund, the Walker Memorial
Ruilding, and, more recently and gener-
ously, for the Technology Fund. If the
proposed alliance is accomplished, the in-
terest of the alumni is sure to diminish
with their diminished responsibility for the
maintenance of the Institute, and may be
altogether alienated. The loyalty of fu-
ture graduates would at best be a divided
sentiment.
[N.S. Vou. XXT. No. 548.
Conclusion.
An institution which has passed beyond
its formative period has a right, as a man
has, to its own character and individuality.
It has earned the right to grow and change
along its own lines, and not to be violently
wrenched out of them and made over,
under new and untried influences, into
something different from itself. Such a
course might be justifiable as a desperate
expedient in the case of a demoralized and
decaying school. But the Institute is in
no sense a decaying institution. While
making no claim to perfection, it desires
nothing so earnestly as a fuller and richer
though not necessarily a larger growth.
In point of numbers, however, the Insti-
tute, despite a steady increase in its re-
quirements for admission and an excep-
tionally high tuition fee, is more than hold-
ing its own, not only in Massachusetts, but
throughout New England, and not only in
New England but throughout the United
States. Our defects—and no one is more
conscious of them or more desirous to
amend them than is the Faculty—are in
part consequences of growth and of suc-
cess. In part, however, they are inevitable
defects of the qualities which have made
us what we are. The lack of academic
leisure and of monumental college sur-
roundings, and the absence of a great part
of the social and athletic life of the typical
American college,—such losses are a neces-
sary price which we and our students pay
for the spirit of professional study, of
business-like regularity, and of scientific
accuracy. In the training of engineers we
believe that these qualities are worth vastly
more than the desirable things which we
sacrifice in order to obtain them. While
continuing to insist upon these qualities,
we shall be glad, so far as we ean safely
do so, to diminish their defects. But we
believe that we ean best accomplish this by
-_ —

remaining free to deal with the problem by
methods under our own control. With that
high regard for the spirit of university life
to be expected from a body of men more
than half of whom, as is the case with this
Faculty, have received their training from
colleges and universities, rather than ex-
clusively from technological schools, we are
nevertheless firmly.convineed that the ef-
fect of direct contact and intermingling of
our student body with the dormitory, social,
and athletic life of college undergraduates,
under the conditions obtaining in this case,
would be more harmful than beneficial, and
that it would be little less than totally de-
structive of the established character and
atmosphere of the Institute.
A successful and valuable school quite
different -from ours might no doubt be de-
veloped under university conditions, but
that would much better be done indepen-
dently, from such beginnings as already
exist, rather than upon the basis of our
reputation and at the cost of our individu-
ality. With institutions, as with men,
character is a thing which may be under-
mined and destroyed, but which can not be
bought or sold or transferred. The success
of the Institute thus far has surely not been
due to its wealth, to its superior equipment,
or to large salaries paid to its instructing
staff. Its suecess has been and still is a
success mainly of character and morale;
and it is precisely these vital qualities
which the Faculty believes would be de-
stroyed by the changes called for under the
terms of this proposed agreement. For it
is not merely proposed to remove the Insti-
tute to a new site, but to graft it upon
another institution.
Very grave questions of policy would at
onee confront the new Executive Commit-
tee in the problems arising from removal
and from the establishment of an entirely
new type of life among our students, and

from the adjustment of working relations:
with the University. The
and differences within the Committee to
which these questions would give rise, and
ought to give rise, might under this agree-
ment lead at any time to one of two
things:— the rupture of the agreement, or
the transfer to the University of a complete
control over the working Institute by the
election of a majority instead of a minority
of the joint Executive Committee from the
membership of the University Corporation.
The adoption of this agreement would
therefore plunge the Institute at once into
a condition of uncertainty concerning the
preservation of its individuality and con-
trol,—an uncertainty probably more preju-
dicial to its organic development than an
immediate and entire surrender of control
would be. Even the full assent of the
Institute to the proposed agreement would
not make it certain that the project is to
be earried out. It would have still to
receive the sanction of the University, the
ratification of the Overseers, and to await
indefinitely various legal proceedings and
decisions. All these contemplated delays
and uncertainties would be further aug-
mented by such other contingencies and
delays as must necessarily arise in carrying
out so vast and complex an undertaking.
This period of uncertainty, extending in-
evitably over five or six years, would be
most prejudicial to the educational work
and to the educational prestige of the In-
stitute.
In closing, the Faculty is glad, in ae-
eordanee with a request made by the Presi-
dent, to take this opportunity to state that
it fully believes in the possibility of co-
operation in effort between Harvard Uni-
versity and the Institute, and trusts that
this may be secured in the future to as
ereat an extent as practicable. There are
necessarily limitations to such cooperation,
controversies:
984 SCIENCE.
but we are convinced that it is possible, by
consultation and conference, to secure a
cooperation thus limited which will prove
beneficial to industrial education in gen-
eral, as well as to the particular work of
both institutions. By the more frequent
interchange of instructors, by allowing to
the advanced students of each institution
such privileges of instruction in the other,
as may be practicable, by the common use
of valuable apparatus, by the participation
in University and Institute seminars of
instructors and students of both institu-
tions, by giving advanced courses of lec-
tures to the combined classes of both insti-
tutions; perhaps by mutual agreement
from time to time tc relegate certain
branches of instruction to one of the two;
by carrying out together advanced engi-
neering researches and tests,—by these,
and by various other ways that will suggest
themselves, much may be accomplished in
harmonious effort which should be highly
beneficial to both the University and the
Institute. This development, however,
must be a growth. It can not be forced,
as the proposed agreement would attempt
to force it, for it is in the nature of con-
tinuous experiment, presenting problems
for the solution of which no data exist.

Madreporaria, Parts III. and IV. By J.
Srantey Garprner, M.A., ete. (From ‘ The
Fauna and Geography of the Maldive
and lLaccadive Archipelagoes, Vol. IL,
Supplement I., pp. 933-957, pls. LX X XIX—
XCTIIT.)
The first installment of Mr. Gardiner’s re-
port on the Madreporaria from the Maldive
and Laccadive Archipelagoes has already been
reviewed in the columns of this journal.*
The second installment, which has just been
received, contains an account of the Fungida
and Turbinolide.

1904.
[N.S. Vou. XXI. No. 548.
III. Fungida.—548 specimens, besides a
number of young forms and fragments, were
obtained. These are divided into 27 species
and 2 varieties, representing 15 genera;
against 24 species and 9 genera reported by
Klunzinger from the Red Sea, and 15 species
and 7 genera found by the author in the
Pacific.
The following is a list of the genera with
the number of species referred to each, and
the names of the forms considered new:
Psammoseris, 1; Siderastrea, 4, S. maldi-
vensis, nov.; Agaricia, 1, A. ponderosa, nov.,
+ var. minikoiensis, nov.; Fungia, 3; Podo-
bacia, 1; Halomitra, 1; Herpetolitha, 1, H.
simplex, nov.; Cycloseris, 2; Diaseris, 1;
Pavonia, 1; Leptoseris, 3, L. incrustans, nov.;
Echinophyllia, 1; Pachyseris, 1; Coscinarea,
2, C. donnani, nov.; Psammocora, 4; P. di-
varicata, Nov.
Mr. Gardiner does not follow yon Maren-
zeller in referring Stephanoseris to the syn-
onymy of Heterocyathus and Psammoseris to
that of Heteropsammia, but combines Ste-
phanoseris and Psammoseris under the latter
name. He goes further and puts the type
species of Psammoseris (P. hemispherica) in
the synonymy of the type species of Stephano-
seris, which was originally described as
Heterocyathus rousseanus.
I somewhat doubt the correctness of the
generic determination of Siderastrea clava, S.
lilacea and 8S. maldivensis. Mr. Gardiner
calls attention to these ‘having in their sur-
face parts the thece of neighboring calices
quite separate from one another, joined to-
gether only by cost, instead of fused to-
gether into a single dividing wall’ This dif-
ference did not escape his attention.
Mr. Gardiner himself doubts his Agaricia
ponderosa really being an Agaricia. I feel
rather confident that it is not an Agaricia.
The type species of the genus is A. undata
(Ell. & Sol.) Lamk; the type specimen is in
the Hunterian Museum, Glasgow, where I
have seen it and Professor J. Graham Kerr has
kindly sent me photographs. The genus can
be briefly characterized as follows: Corallum
compound, thin, foliaceous. Common wall
imperforate, naked, finely striate; no differen-

tiated corallite walls. Calices forming more
or less definitely concentric series, which are
bounded below by a subealicular swelling or
ridge; there is no swelling or ridge above, the
septo-coste running directly to the next series.
Septa well developed, distinctly radiate, im-
perforate. Columella a_ single tubercle.
Agaricia fragilis (Dana) agrees in. generic
characters with the type and is a closely re-
lated species.
I think that Mr. Gardiner’s criticism of
Professor Déderlein’s monograph, ‘ Die Koral-
lengattung Fungia,’ is in some respects too
severe. He says: “It is quite clear that that
author [Déderlein] has, generally speaking,
no scientific basis for his description of ‘ va-
rieties.’” The word variety is difficult to de-
fine in a manner that will be satisfactory to
all systematists, and Mr. Gardiner himself is
guilty of an inconsistency. Under Fungia
dentigera, he speaks of ‘a true variety, the
separating characters of which are discon-
tinuous. If the characters are discontinu-
ous, the specimens belong to a distinct species.
Mr. Gardiner in Part I. of his ‘ Madreporaria
of the Maldives and Laccadives’ says ‘ dis-
continuous or specific’ variation. Variation
in corals is so complex and its causes are so
little understood that one should be very
lenient in criticizing the efforts of a fellow
worker to handle its phenomena. ‘There are
mistakes in Doéoderlein’s work; some of his
varieties can not be maintained by any of
the usually accepted canons of zoological
nomenclature, but his work is earnest and he
has much advanced our knowledge of the
genus F'ungia.
I am glad to see that Mr. Gardiner con-
siders Podobacia a valid genus, and heartily
agree with him in that course.
As regards Cycloseris and Fungia, I agree
with Déderlein. The only possible basis for
their separation into two genera would be in
Cycloseris having originally only six primary
septa and Hungia twelve. The validity of
this character is extremely doubtful, as it
rests on a very slim foundation.
Without entering into a discussion of my
reasons, I will state that I believe Quelch was
correct in uniting Cycloseris and Diaseris,
SCIENCE,
985
and, as stated in what precedes, I agree with
Déderlein in combining both with FPungia.
IV. Turbinolide—The number of. speci-
mens collected is not given. Six species, rep-
resenting 4 genera, are referred to the Tur-
binolide. They are Flabellum, 2, F. multi-
fore, nov.; Tropidocyathus, 1, T. cooperi, nov.;
Heterocyathus, 1; Paracyathus, 2.
Mr. Gardiner’s paper is an important con-
tribution to the literature of reef corals. He
gives valuable notes on variation, careful de-
seriptions and figures all the forms described
as new and several of those referred to pre-
viously described species.
The studies being made on the coral faunas
of the Pacific and Indian oceans are bringing
out many interesting facts of their geograph-
ical distribution. I have just completed a
study of the Hawaiian Fungida, and may be
pardoned for comparing them with those from
the Indian Ocean. The following is a list of
the species, with notes on their occurrence
elsewhere: Fungia (Oycloseris) patella (Ell.
& Sol.), east coast of Africa, ete.; Fungia
(Diaseris) fragilis (Aleock), Indian Ocean;
Fungia scutaria var. dentigera Leuckart,
Indian Ocean, ete.; [FPungia oahensis Déder-
lein; Fungia paumotensis Stutchb. (fide
Quelch), Philippines, ete.; FPungia echinata
(Pallas) (fide Studer)]* Indian Ocean, ete.;
Bathyactis stephana Alcock, Indian Ocean;
Stephanaria stellata Verrill, Panama; Ste-
phanaria n. sp.; Pavona varians Verrill, aff.
P. repens Briiggemann; Pavona n. sp.; Lep-
toseris (1) n. sp., aff. LZ. fragilis M. Ed. & H.;
Leptoseris (2) n. sp.; Leptoseris (3) n. sp.,
aff. L. papyracea (Dana); Leptoseris (4) n.
sp.; Psammocora, aft. P. superficialis Gar-
diner.
A fair proportion of the species actually
occur in the Indian Ocean, some as far west
as Africa, or have there analogues so similar
that specific separation is doubtful. As would
be expected, the Panamic fauna is represented
to some extent.

Contributions to the Study of Sulfur. I. The
Metabolism in Brombenzol Poisoning: W.

Administration of brombenzol to dogs re-
sulted in increased elimination of nitrogen
and urea. Urea closely followed total nitro-
gen. Preformed ammonia was decreased.
Creatinin elimination was not appreciably
affected. Total sulfur excretion was not in-
creased, but there was almost complete sup-
pression of alkali sulfates. Excretion of
neutral sulfur, represented for the most part
in this case by parabromphenyl-mercapturic
acid, was increased 400 per cent. Ethereal
sulfate elimination was markedly increased.
Total sulfate-sulfur was diminished. Excre-
tion of chlorin and phosphorus was practically
unaffected. Nitrogen and fat were increased
in the feces. The drug caused ulceration of
the stomach and intestines, and degeneration
of the liver and kidneys.

On Experimentally Produced Variations in the
Energy of Tumor Growth: Leo Lors. (Pre-
sented by James Ewing.)
The author’s observations point to the gen-
eral conclusion that it is possible to cause an
experimental increase or decrease in the en-
ergy of tumor growth. Such variations may
be brought about by direct stimulating or de-
pressing influences on the tumor cells. The
stimulation effects may become cumulative.

charts of Hybrid Poultry, with Remarks:

Dr. Davenport exhibited photographs and
plumage-charts of four hybrids between dif-
ferent races of poultry, and also of their
parents, and remarked on the nature of the
inheritance illustrated by each example.
Experimental Cirrhosis of the Liver: RicHarp
M. Pearce. (Presented by Eugene L. Opie.)
Necrotic lesions were produced in the liver
of the dog by injections of hemolytic immune
sera of high hemagglutinative power. The
author’s observations have demonstrated that
cirrhosis may follow extensive primary de-
structive lesions produced in this way (a view
not yet fully accepted) and thus support the
contention of Kretz that cirrhosis is essen-
tially the result of a series of repair processes
following repeated injuries of liver paren-
chyma.
Experimental Arteriosclerosis: Ricuarp M.
Pearce and E. McD. Stanton. (Presented
by J. E. Sweet.)
Intravenous injections of adrenalin produce
in rabbits vascular lesions that are limited
to the aorta and that exhibit more or less
definite sequence.’ Five to six injections of
3 to 25 minims of 1-1,000 solutions every
24-48 hours for long periods cause at first
histologically important changes in the media.
After about 12-15 injections very definite
lesions are evident macroscopically. In the
experiments continued for 6-8 weeks, the
process becomes very diffuse and small dila-
tions of the thinner portions of the aorta as-
sume the appearance of aneurisms. At this
stage the destruction of the elastic fibers is

extreme and all degenerated areas are in-
filtrated with calcium salts.
Whether the vascular changes are due to a
primary toxic action of the adrenalin or
whether they are the result of the increased
arterial tension which it causes, has not been
determined.
On the Chemical and Physiological Properties
of Ricin, with Demonstrations: Tuomas B.
OsporNE and LarayetTE B. MENDEL.
The most active preparation proved fatal
when administered subcutaneously to rabbits
in the small dose of 0.0005 malligram per kilo
of body weight. The toxic constituent of the
castor bean appears to be an albumin. Ricin
is like other albumins in composition, heat
coagulation, color reactions, precipitation re-
actions, specific rotation, state of combination
of its nitrogen, ete. By tryptic digestion the
agglutinating power of pure ricin may be
greatly impaired or destroyed. The experience
of the authors lends no encouragement to at-
tempts to ‘purify’ such toxins by methods
designed to eliminate proteid substances from
the active materials.
On a Method of Determining Indol, with
Demonstrations: C. A. Herrer and M.
Loutse Fosrrr.
The authors described a rapid and accurate
means of determining indol. It is based on
the fact that indol, in slightly alkaline solu-
tion, readily condenses with naphthoquinon
sodium mono-sulfonate and forms a_ blue
crystalline compound that is only very slightly
soluble in water but is readily extracted by
chloroform from a watery solution or suspen-
sion. The condensation product is di-indyl
naphtho-ketone mono-sulfonate. Its solution
in choloroform is red. The method is well
adapted for colorimetric or gravimetric deter-
minations.
Anesthesia Produced by Magnesium Salts,
with Demonstrations. A Preliminary Com-
munication: 8. J. Metrzer and Joun Aver.
The authors exhibited two guinea pigs which
were deeply narcotized by subcutaneous injec-

dose of magnesium salt is not too large, heart
beat, blood pressure and respiration remain
nearly normal during periods of narcosis in
which any operation can be performed without
resistance. Certain maximum doses can not
be exceeded without causing extremely toxic
effects.
Enzymes and Anti-enzymes of Inflammatory
EHaudates; Eugene L. Opts.
Inflammatory exudates removed from the
pleural cavities of dogs one or two days after
injection of the irritant (aleuronat) undergo
very little change, while those removed three
or more days after the onset of inflammation
exhibit appreciable though slight autolysis.
There is no relation between the amount of
digestion and the number of cells which are
present. The serum inhibits autolysis in a
suspension of the cells separated by centrif-
ugalization. The antilytic action of the
serum is favored by an alkaline reaction, but
is completely prevented in an acid medium.
The serum of the exudate contains a pro-
teolytic ferment’ which is. active only in an
acid medium. In the later stages of such
inflammations there is some diminution of the
antilytiec power of the exudate.
Shallow Well Waters of Brooklyn: Jamus P.
ATKINSON.
The author’s observations justify the con-
clusions that the sandy soil of Brooklyn can
not be relied upon as a safe filter for the well
waters of that borough, that Brooklyn soil
in populous districts seems to be nearing the
saturation point for sewage, and that many
of the shallow wells in Brooklyn are, there-
fore, in growing danger of serious pollution.
The Influence of the External Temperature
upon the Viscosity of the Blood: Russpiu
Burton-Opitz.
The author has found that the viscosity of
the ‘living’ blood can be greatly influenced
by changing the external temperature. Vis-
cosity was markedly increased in dogs im-
mersed in water at 25° C. Warm water baths
(42°-45° ©.) produced a corresponding de-
erease in the viscosity. Specific gravity of
the blood showed corresponding variations.

The Changes in the Viscosity of the Blood
during Narcosis; RussELL Burron-Opirz.
It was found that the viscosity of the blood
is increased by deep ether or chloroform nar-
cosis and lessened during light anesthesia.
Specifie gravity of the blood was increased by
deep and lessened by light ether narcosis.
Chloroform, on the other hand, produces a
slight deerease during deep and an increase
during light narcosis. Hence the specific
gravity can not be regarded as a-perfectly ac-
curate index of the viscosity.
Studies of the Effects of Radiwm on Plants
and Animals, with Demonstrations: Com-
municated by WituiamM J. Giss.
I. Preliminary notes on the effects of
radium rays on plants. C. Stuart Gager.
Plants are stimulated. For this stimulus
there are minimum, optimum and maximum
points, depending upon the proximity of the
radium to the plant, the strength, quantity
and condition of the radium salt, the time of
exposure and the nature and condition of the
tissue.
II. The action of radium rays on Amaba
proteus and upon other microorganisms.
Louis Hussakof. No visible effects were pro-
duced, by even the strongest radium prepara-
tions, during periods of observation of about
an hour.. The water surrounding the animal
in each experiment may have prevented ra-
diant effects.
III. The effects of intravenous injections of
radium bromid. Russell Burton-Opitz and
G. M. Meyer. Increased blood pressure,
caused by general vasoconstriction, always
promptly followed injection of radium prepara-
tions in small dogs. This effect was soon
followed by a fall of pressure, due to decrease
in frequency and accompanied by irregularity
of the heart. The variations in blood pressure
were extreme. These effects occur after divi-
sion of both vagi. Respiration gradually de-
creases in frequency until respiratory paral-
ysis results. A striking qualitative similarity
was found to exist between the effects of
pure barium bromid and radium _ bromid
preparations of low activity (240 and 1,000).

THE NEW YORK ACADEMY OF SCIENCES.
OF GEOLOGY AND MINERALOGY.
At the meeting of April 3, 1905, Professor
Stevenson presiding, the following papers were
read:
The Physiography of the Adirondacks: J. F.
Kemp.
The Adirondacks cover some 10,000 square
miles, and except for the White Mountains
of New Hampshire and the Blue Ridge of
North Carolina, are the loftiest summits east
of the Black Hills of Sotth Dakota. They
are metamorphosed Precambrian sediments
and eruptives with a surrounding fringe of
Paleozoics beginning with the Potsdam and
ending with the Utica, except for the Glacial
drift. The eastern portion is mountainous,
the western a high plateau which slopes to
Lake Ontario. Three peaks exceed 5,000
feet. The general profile of the mountains
is serrate, but there is great variety of shape.
There are two contrasted types of valleys.
One type, doubtless an instance of greater
geological antiquity, presents gentle slopes and
great maturity of form. Its members run
SECTION
_east and west, and north and south, and are
occupied in some cases by the larger lakes.
The second type is more recent, and is due
to faulting. The valleys have on one or both
sides precipitous escarpments. The cliffs run

northeast and southwest or northwest and
southeast. A third series of breaks running
nearly due north is also at times in evidence.
The faults are most often the result of differ-
ential movements causing even a marked
sheeting of the rocks. The faults run out
into the Paleozoic areas, and are shown with
diagrammatic distinctness, where they have
been especially described by H. P. Cushing.
The problem of the drainage is of especial
interest. All the waters go ultimately either
to the Hudson or the St. Lawrence. The
courses of the large streams follow sometimes
the older type of valleys, sometimes ‘the later.
Barriers of drift have often driven them from
their old lines across low, preglacial divides
into new ones. The courses of the Hudson
and Onondaga are particularly striking illus-
trations, each exhibiting one or more marked
bends to the eastward. The courses of the
two were described and discussed in some
detail.
The different types of lakes were also de-
scribed including the river valleys ponded
by barriers of drift, the fault valleys and
the relations to the older type of depression.
The nature of the ice invasion and its modi-
fying effects were passed in review, chiefly
along the work of I. H. Ogilvie. With a brief
statement of the Post-glacial lake-fillings, ete.,
which have been especially set forth by C. H.
Smyth, Jr., the paper closed.
The Paleogeography of Mid-Ordovicic Time:
CuHartes P. BrerKey.
Both the Cambric and Ordovicic formations
contain prominent sandstone strata alter-
nating with dolomites wherever exposed in
Michigan, Wisconsin, Minnesota, Iowa, IIli-
nois, Missouri, Arkansas and Indian Terri-
tory. The northern margin, however, is pre-
vailingly more arenaceous than the southern,
where shales replace many sand beds. At still
greater distance, in Ohio, Kentucky and Ten-
nessee, these are in turn represented by lime-
stones largely.
The uppermost one of the series is the St.
Peter. This sandstone, as well as each of the
more important ones below, is believed to rep-
resent an extensive retreat and re-advance of

the sea. Few marks of the erosion intervals
are preserved. Only here and there has the
mantle of sand permitted much attack upon
the underlying dolomite, and the reworking of
the sands themselves has obliterated most in-
ternal evidence of such history.
Much of the sand, furthermore, is wind-
blown. This reworking by the sea and the
wind is believed to be the chief cause of the
extreme purity of the St. Peter.
The St. Peter stage of the Ordovicic, there-
fore, represents a retreat of the Mississippian
sea from the vicinity of Lake Superior to
probably as far as Ohio, southern Illinois and
Arkansas, followed by a readvance to its
original position. The northern part of the
St. Peter contains a sedimentary break. In
part it is both older and younger than the
same formation in its southern extension,
while, on account of the reworking accom-
panying the sea advance, there is greater con-
formity with overlying than with underlying
beds. A. W. GRABAu,
Secretary.
At the meeting of May 1, 1905, Vice-
President Hovey presiding, the following
papers were read:
The Pleistocene Beds of Sankaty Head, Nan-
tucket: J. Howarp WInson.
When visited by early explorers, the section
at this locality was kept freshly exposed by
the cutting back of the bluff by the sea, but
for quite a period of years this has been pre-
vented by the northward extension of the
Siasconset apron beach, so that the face of
the bluff is now covered with talus and over-
grown with beach grass.
The locality was visited during the summer
of 1904 and considerable work done in ex-
posing the section and making a collection of
the fossils.
This work resulted in the collection of 81
species, 21 of which had never been reported
from this point, including Pandora crassidens

above the Miocene, and Serripes laperonsii

tens belonging to the Arctic fauna of the
Pacific coast and not heretofore reported east
of Point Barrow.
A number of facts differing somewhat from
those reported by former observers were no-
ticed and have resulted in a somewhat differ-
ent interpretation for the phenomena pre-
sented by these deposits.
The deposits are not of glacial origin, for
(1) numerous delicate and unworn shells oc-
cur; (2) bivalves such as Solen, Venus and
Mya occur in the position in which they lived
with both valves together, and in the case of
Venus, with the ligament in place; (3) the
faunas are not mixed as would be the case if
of glacial origin, the lower beds containing
shoal-water species of a southern range, and
the upper, deeper water species of a northern
and even Arctic type.
The lower beds were deposited in a shallow
inlet or lagoon, as shown by such species as
Mya, Ostrea and Venus and especially by
numerous mud crabs and the presence of our
edible crab, Callinectes sapidus, while the
upper beds were deposited during a subsidence
of the area contemporaneous with the advance
of the Wisconsin ice sheet, as shown by the
deeper water and more northern species.
After the destruction and washing into the
lagoon of the protecting barrier beach, as
shown by the overlying rounded and pure,
white sands, the ice reached and passed this
point, eventually burying the beds under fifty
feet or more of drift. Later, a reelevation
took place, bringing the land to about its
present position.
Early Stages of some Paleozoic Corals; C. E.
GORDON.
J. E. Duerdon in the Johns Hopkins Uni-
versity Circular for 1902 has endeavored to
show by studies based on Lophophyllum pro-
liferum that the Rugosa exhibit a hexameral
plan of growth of the primary septa, in so far
as L. proliferum may be taken as representa-
tive. Certain studies on Streptelasma pro-
fundum show a primary tetrameral plan. The
fact that S. profundum is a middle Ordovicie
type suggests that this is the primitive con-
dition. Moreover, a careful examination of
[N.S. Von. XXI. No. 548.
Duerdon’s figures shows that they lend them-
selves to an entirely different interpretation
from that which Duerdon gives. This inter-
pretation is that two of the so-called primary
septa are secondary septa precociously devel-
oped; that their sequence and ultimate posi-
tion are the same as those for the secondary
septa which appear in the corresponding posi-
tions in the corresponding quadrants of a
zaphrentoid coral; that the fossula and car-
dinal septum are on the concave side of the
corallum; and that if Duerdon’s figures be
inverted they reveal a perfect similarity to a
zaphrentotd coral, as far as the order of ap-
pearance and the arrangement of the septa
are concerned.
The fact that LZ. proliferum is of Carbonic
age indicates that it is a modified type of the
zaphrentoid coral, the first secondary septa
appearing in nepionic stages and thus simula-
ting the character of primary septa.
A New Lower Tertiary Fauna from Chappa-
quiddick Island, Martha’s Vineyard:
Tuomas C. Brown.
A few years ago while studying the Cretacie
deposits of Long Island, Block Island and
Martha’s Vineyard, Dr. Arthur Hollick made
a collection of fossil molluses and plants from
Chappaquiddick Island. The fossil molluses
were deposited in the Columbia University
collection without being fully and carefully
studied.
These fossils occur in the island in ferrugi-
nous concretions. They seem to have been
deposited somewhere to the north of where
they are now found, then moved as glacial
drift, reassorted and deposited in their present
position. From their lithological similarity
to concretions containing undoubted Cretacie
fossils found elsewhere on Martha’s Vineyard,
Dr. Hollick thought that these concretions and
their contained fossils must be of Cretacic
age.
Professor Shaler noted the occurrence of
these concretions and their similarities to the
Cretacie drift, but being unable to find any
distinctive organic remains hesitated to set
them down as Cretacic.
Professor R. P. Whitfield considered that
7
JUNE 30, 1905.]
these rocks could hardly be Cretacic, since the
fossils were of a more recent type.
A careful study of the fossils has shown
that this material is not Cretacie but Eocene
in age. This fauna from Chappaquiddick
represents a new and distinct Eocene province,
differing from all the other Eocene provinces
of the Atlantic coast, but no more widely
different from these than they are from one
another. Although in this fauna there are
several species somewhat resembling those of
the provinces to the south, on the whole it
would seem to be more closely allied to the
Eocene of England. The genera most abun-
dantly represented in these Chappaquiddick
deposits, e. g., Modiola, Glycymeris, are also
among the most abundant in the English de-
posits. These same genera, although repre-
sented in the Atlantic and gulf provinces, are
there more sparsely distributed and occur with
other more abundantly represented genera
that appear to be altogether wanting in the
Chappaquiddick deposits.
A comparison of this Chappaquiddick fauna
with other Eocene faunas indicates that it is
of lower Eocene age, the species most closely
resembling those found in this fauna being
found in the lower beds of the Atlantic and
gulf provinces, the Tejon of California and
the lower beds of England. These deposits
may possibly be of the same age as the Shark
River beds of New Jersey, but being deposited
in a region separated from this have no forms
in common with it. But such correlation
could be only conjecture. As the correlation
of the well-known Eocene deposits is even yet
very uncertain it is unnecessary and impossi-
ble to place these beds any more definitely than
simply to say that they are Lower Eocene.
Structural Relations and Origin of the Limo-
nite Beds at Cornwall, N. Y.: O. A. Harrt-
NAGEL.
The limonite at the Townsend iron mine,
near Cornwall in Orange County, N. Y., is
found at the base of the New Scotland beds
where the latter are in contact with the Long-
wood red shales. The source of the iron is
evidently from the red shales but whether the
contact was due to overlap or faulting has not
been previously explained. Two thirds of a

991
mile north of the mine the Decker Ferry,
Cobleskill, Rondout, Manlius and Coeymans
formations, having a total thickness of 95
feet, are found between the New Scotland and
Longwood beds. In the region of the mine
the strata are nearly vertical and in faulting
a wedge-shaped block was forced up, bringing
the red shales in contact with the New Scot-
land beds. A cap of limestone has until re-
cent geologic times protected from erosion the
mass of soft Longwood shales which now form
a steep hill, but which is rapidly being worn
away.
Types of Sedimentary Overlap: A. W.
GRABAU.
With a normal sea shore, a rising sea level
will produce the phenomenon of progressive
overlap, a falling sea level that of regressive
overlap. If the sea transgresses slowly, and
the rate of supply of detritus is uniform a
basal rudyte or arenyte is formed which rises
in the column as the sea advances, and whose
depositional off-shore equivalents are succes-
sive beds of lutytes or organic deposits (bio-
genics). Types of such basal beds which pass
diagonally across the time scale, are seen in
the basal Cambric arenytes of eastern North
America, which as the Vermont Quartzite are
lower Cambric, and as the Potsdam are Upper
Cambric. Again in the Basal Cretacic
arenyte of southwestern United States, this
is shown, these being basal Trinity in Texas,
Washita in Kansas, and Dakota or later on
the Front Range. Examples of this type of
progressive overlap are numerous and famil-
iar. On an ancient peneplain surface the
transgressing sea may spread a basal black
shale, as in the case of the Eureka (Noel)
Black shale, which is basal Choteau in south-
ern Missouri and basal Burlington in north-
ern Arkansas. Regressive movements of the
shore succeeded by transgressive movements
give us arenytes which are enclosed in off-
shore sediments and which within themselves
comprise an hiatus the magnitude of which
diminishes progressively away from the shore.
An example of this has recently been discussed
by Berkey * who finds that the St. Peter Sand-
stone in Minnesota marks the interval from
* See ante, April meeting.
992
lower Beekmantown to upper Stones River,
which interval is represented by several thou-
sand feet of calcareous sediments in other
regions distant from the shore of that time.
In marine transgressive overlaps, later
members overlap earlier ones toward the
source of supply, 2. e., towards the old-land.
In non-marine progressive overlaps, later
members overlap the earlier ones away from
the source of supply. Thus in a growing
alluvial cone, the later formed beds will extend
farther out on to the plain away from the
mountain. If several successive fans of this
type are formed one above the other, owing
to successive elevations of the source of sup-
ply, only the latest beds of each delta will be
found on the outer edge of this compound
delta, the hiatus between the beds being fur-
ther emphasized by the erosion which the last
bed of the first delta underwent during the
time that the early beds of the second delta
were deposited nearer the source of supply, 7. e.,
before the last bed of the second delta covered
up the remnant of the last bed of the first
delta and thus protected it from further ero-
sion. A good example of this type of overlap
appears to be presented by the Pocono, Mauch
Chunk and Pottsville beds of the Appalachian
region. These formations are with exception
of the negligible Greenbrier member, of non-
marine origin, representing the wash from the
growing Appalachians. In western Pennsyl-
vania only the latest beds of each (barring
portions removed by erosion between the dep-
osition of the successive fans) are found rest-
ing one upon the other, the interval between
the beds becoming less and less toward the
anthracite regions. A. W. GRasau,
Secretary.
SECTION OF BIOLOGY.
Ar the April meeting Professor H. F. Os-
born presented a discussion of ‘The Ideas and
Terms of Modern Philosophical Anatomy,’ and
Dr. O. R. Hay described ‘Turtles of the
Bridger Basin.’ The full abstract of Professor
Osborn’s paper was published in Scrence
for June 23. Dr. Hay gave a brief descrip-
tion of the extent of the Bridger beds and of
the nature of the materials composing them.

He expressed the conviction that these deposits
had not been made in a lake, but over the
flood-grounds of rivers. The region was
probably covered with forests, and teemed with
animal life. In the streams were numerous
turtles. Many species of these have been de-
scribed by Dr. Leidy and Professor Cope. In
the speaker’s hands are materials for the de-
scription of about a dozen more species. The
American Museum party of 1903 collected
many specimens of the genus and these have
furnished good skulls, neck, shoulder and pel-
vie girdles, and the limbs. These materials
confirm the validity of Lydekker’s group called
Amphichelydia, and show that from it sprang
the modern super-families Cryptodira and
Pleurodira.
At the May meeting of the section papers
were presented by Professor E. B. Wilson on
‘ Observations on the Chromosomes in Hemip-
tera,’ and by Professor H. E. Crampton on
‘Correlation and Selection.’
Professor Wilson’s paper presented the re-
sults of an examination of the mode of distri-
bution of the chromosomes to the spermatozoa
in Lygeus turcicus, Cenus delius, Podisus
spinosus and two species of Huchistus. In
none of these forms is an accessory chromo-
some (in the ordinary sense) present, all of the
spermatozca receiving the same number of
chromosomes, which is one half the sperma-
togonial number (the latter number is in
Podisus sixteen, in the other forms fourteen).
In all these forms, however, an asymmetry of
distribution occurs such that two classes of
spermatozoa are formed in equal numbers, both
receiving a ring of six chromosomes (in
Podisus seven) that are duplicated in all the
spermatozoa, and in addition a central one
which in one half the spermatozoa is much
smaller than in the other half. These cor-
responding but unequal chromosomes (which
evidently correspond to some of the forms-
described by Montgomery as ‘chromatin
nucleoli,’ and agree in mode of distribution
with that which this author has described in
the case of Huchistus tristigmus) may be called
the ‘idiochromosomes.’ They always remain
separate in the first division, which accord-
JUNE 30, 1905.]
ingly shows one more than one half the sperma-
togonial number of chromosomes, but at the
close of this division conjugate to form an
asymmetrical dyad, the number of separate
chromatin-elements being thus reduced from
eight to seven (in Podisus from nine to eight).
A reduction of the number to seven in the
first division, such as has been described by
Montgomery as an occasional or usual process
in Huchistus and Canus, was never observed.
In the second division the asymmetrical idio-
chromosome-dyad separates into its unequal
constituents, while the other dyads divide sym-
metrically. One half the spermatozoa, there-
fore, receive the large idiochromosome and one
half the small, the other chromosomes being
exactly duplicated in both.
Correlated with this asymmetry of distribu-
tion is the fact that the spermatogonial chro-
mosome-groups do not show two equal micro-
chromosomes (as is the case in such forms as
Anasa, Alydus or Protenor, where an accessory
chromosome is present) but only one, which is
obviously the small idiochromosome, the large
one not being certainly distinguishable at this
period from the other spermatogonial chromo-
somes. The final synapsis of the idiochromo-
somes is deferred to the prophases of the second
division, somewhat as that of the two equal
microchromosomes is deferred until the pro-
phase of the first division in Anasa, Alydus
and some other forms. A remarkable result
of the difference in this regard between the
forms that possess and those that lack a true
accessory chromosome is that in the former
ease (Anasa, Alydus, etc.) the first division of
the small central chromosome is a reduction-
division and the second an equation-division;
while in the latter case (Lyge@us, Canus, ete.)
the reverse order manifestly occurs. The rela-
tion of these observations to earlier ones by
Paulmier, Montgomery and others was pointed
out, with a discussion of their bearing on the
Mendelian phenomena of heredity and the
problem of sex-determination.
Professor Crampton presented briefly some
of the conclusions drawn from the results of
his work upon variation, correlation and selec-
tion among saturnid lepidoptera. The earliest

studies showed that eliminated individuals,
when compared with similar members of the
same group that survive, prove to be more
variable and of somewhat different types,
although this relation between variability and
selection is not a constant one. The charac-
ters utilized for these preliminary studies,
namely, certain pupal dimensions and propor-
tions were of such a nature that they could not
serve the pupa directly in any functional man-
ner, wherefore it was concluded that their con-
dition of correlation formed the actual basis
for the selective process, formative correla-
tion being also distinguished from functional
correlation. That the general condition of
correlation among the structural characters of
pups formed, indeed, the basis for selection
was further indicated by the results of a sta-
tistical study of the correlations between vari-
ous characteristics of pupal groups from several
different animal series; although an advantage
did not always appear in favor of the surviving
group. On the basis of the foregoing, a gen-
eral theoretical conception was developed, ac-
cording to which the whole series of internal
elements and the whole series of external in-
fluences were regarded as involved in the
determination of the general condition of cor-
relation or coordination that formed the basis
for selection, as adaptive or the reverse.

DISCUSSION AND CORRESPONDENCE.
PRE-PLEISTOCENE DEPOSITS AT THIRD CLIFF,
MASSACHUSETTS.
To tue Eprror or Science: It has been
suggested by several writers (Shaler and Ver-
rill) that Tertiary and Cretaceous deposits
may occur on the floor of the sea north of
their known occurrence on Marthas Vineyard
and Cape Cod. ‘Their northerly occurrence
on land has not been noted except for the
Miocene greensands at Marshfield, Mass.
(Duxbury sheet, U. S. G. S.). During the
spring field season at Harvard University the
writer reexamined the coast from Boston

east of Plymouth harbor, in order to test, by

means of the excellent cliff sections, the sug-
gestion of the occurrence of such deposits.
Pre-Pleistocene deposits were found at Third
Cliff, twenty miles southeast of Boston, and
possibly at Peaked Cliff, southeast of Ply-
mouth.
The section at Third Cliff shows yellow
clays at the base conformably overlain by
yellow and white sands and succeeded by a
bed of bright red sands with an unconformity
at their base. On the eroded edges of the
red and white beds are deposited dark, glau-
conitie and lignitic clays and sands. The
entire series of beds has a total maximum
thickness of sixty or seventy feet, and out-
crops for a half mile along the cliff face.
Absolutely no erratic material occurs either
within the beds themselves or along the lines
of unconformity.
The lithologic characters of the lower beds
are like those so persistently characteristic of
the Cretaceous from Marthas Vineyard to
New Jersey; while the upper beds of dark
clays appear to be homologues of the Miocene
at Gay Head and at Marshfield. This fact,
together with the evidence of the unconformi-
ties and of the lignites is being examined
with a view toward suggesting probable cor-
relations with the deposits worked out at Gay
Head by Professor Woodworth (Bull. Geol.
Soc. Amer., VIII., 1897, 197-212); although
the absence of specific paleontologic evidence
renders such correlation merely tentative.
The detailed descriptions of the beds and the
conclusions inferred with respect to their age
will be published in a later paper. ”

THE BRAIN OF THE HISTOLOGIST AND PHYSIOLOGIST
OTTO C. LOVEN.
Proressor Lovén, the Swedish histologist
and physiologist who will be best remembered
for his discoveries of the endings of the taste-
fibers in the papille of the tongue of mammals,
as well as of the vaso-dilator nerves, had ex-
pressed it as his wish that his brain be pre-
served after death and studied by his friend
and associate, Gustaf Retzius.
With characteristic care and skill Professor
Retzius has just published his studies upon
Lovén’s brain in Biologische Untersuchungen,
Vol. XII., 1905. The brain exhibits a richness
of fissures and these are marked by a superior
degree of tortuousness and ramification. The
subparietal region is very complex in its sur-
face configuration, while the central (motor)
regions are only moderately developed. The
cortical centers for speech and language for-
mation are notably large, and Professor
Retzius brings this fact into relation with
Professor Lovén’s notable powers of clear, ex-
act and logical expressions of thought in
words; less so in the way of oratorical finesse
than in the talented use of the best and most
adequate expressions. The weight of the
brain is not given in this report though its
size is said by Retzius to have been well above
the average. Epw. AnTHoNy SPITZKa.

trouble. They were of the first grade, each
fruit wrapped in paper, and packed in a bushel
box. The financial loss was important, as a
JuNnr 30, 1905.)
considerable amount of high priced fruit had
been ruined.
Scattered irregularly over the surface of
each apple were conspicuous spots of various
sizes where the epidermis was dead, discolored
and slightly sunken. Each spot was nearly
circular, though on some apples the adjacent
spots had coalesced, forming a large affected
area of irregular shape. Beneath each spot
to a depth of a few millimeters, the flesh was
dead, shrunken and dry, appearing as though
affected with a dry rot. There was no dis-
agreeable odor or taste to the dead flesh or
epidermis.
In the center of each of the smaller spots,
and scattered over the larger affected areas,
were small bodies resembling the pyenidia of
a fungus, but examination showed them to be
only the normal lenticels of the apples.
Failure to find either fungi or bacteria as a
cause of the injury led to the belief that some
treatment of the fruit, such as fumigation,
might be a cause. Sulphur, being commonly
used for fumigation, was experimented with
to note the effects of the fumes upon ripe
apples. Fruits of different varieties including
Esopus Spitzenburg were placed in a bell jar
which was then filled with sulphur fumes.
After five minutes the fruit was removed and
found to have developed numerous spots that
were in every way identical with those on the
apples received for examination.
This experiment was repeated many times
with wet and with dry fruits, but the charac-
teristic spots were always produced. The
spots continued to enlarge for some time after
the fruits were removed from the fumes.
The presence of a lenticel in the center of
each spot would indicate that the sulphur
dioxid passes into the fruit at this point and
causes the bleaching of the tissue. A similar
effect was produced where an artificial break
in the epidermis was made. A lenticel makes
a strong color contrast with the bleached epi-
dermis, thus giving it the appearance of a
pyenidium.
Sulphur was the only substance used in
these experiments; it is possible that other
chemicals would produce a similar injury.

THE FLOATING LABORATORY OF MARINE
BIOLOGY OF TRINITY COLLEGE.
ARTICLES of incorporation have been filed
with the secretary of the state of Connecticut
‘to establish and maintain a floating labora-
tory of marine biology for exploration in
oceanography and the collection and investiga-
tion of the organisms of the sea; to supply
colleges, museums and other institutions with
material for investigation, study and exhibi-
tion.’
A vessel of about ninety tons burden will
be secured and equipped with the necessary
dredges, trawles, tangles, tow-nets, etc., as
well as chemical reagents and glassware for
work in marine zoology and botany. When
the boat is anchored in a protected harbor im-
mediately it becomes a laboratory. The vessel,
in sailing from place to place in the ocean,
will furnish most favorable facilities for the
investigation of the distribution and variation
of organisms. On each expedition it is
planned to stay in some particularly desirable
locality for about one month so that problems
of eytology, embryology and physiology may
be undertaken. Competent preparators, art-
ists and photographers will be on the staff so
that not only museums and laboratories may
be supplied with material, but an effort will
be made to meet the specifications of investi-
gators as to fixation and preservation, together
with sketches, or photographs, of the organ-
isms desired for their work. In going to a
new region each summer large collections for
research will be made year after year and it
is hoped to greatly extend our knowledge of
the local faunze and flore of the western At-
lantic.
In the early summer of 1906 the vessel will
sail to the Bahamas. After a month in the
sub-tropics the boat will weigh anchor for the
eruise northward, making a harbor every hun-
dred miles or so for the purpose of getting
material for comparative studies. In the
Bahama Islands the conditions are very fa-
vorable for the most abundant and varied
organisms since these islands are situated in
the mouth of the Gulf Stream where it de-
bouches between Florida and Cuba, bringing
with it myriads of creatures caught up in the
996
wide cireuit of the current from the equator
and through the Gulf of Mexico. The cli-
mate, though warm, is agreeable in summer
and usually keeps between 84° and 86°. The
trade winds blow steadily, the waters are clear
and the people honest and simple hearted.
Biological investigators have already found
the life there in summer both interesting and
delightful. These healthful conditions are
of great importance for northern men when
working hard with both mind and body on the
edge of the tropics.
While this project centers in Trinity Col-
lege, shares have been taken by those inter-
ested in other institutions and it is in the
largest way for the benefit of all investigators
who care to take advantage of the opportuni-
ties offered. CuHarues L. Epwarps.
FEDERICO DELPINO.
By the death, at the age of seventy-two, of
Professor Federico Delpino, of the University
of Naples, modern botany has lost one of its
pioneers. For, according to Friedrich Lud-
wig, a leading authority on the subject, the
foundations of plant biology were laid by the
publication in 1867 of Delpino’s ‘ Thoughts on
Vegetable Biology, on Taxonomy and on the
Taxonomic Value of Biological Characters.’
Born at Chiavari, in the province of Genoa,
his childhood was largely passed in the garden
of his father’s house, where he studied closely
the habits of ants, bees and wasps and suc-
ceeded in discovering the mode in which the
great blue-black bee, Xylocopa violacea, con-
structs its nests. His education was the
classical one usually given to an Italian boy
of that day, and his employment for nearly
ten subsequent years was in the routine of
the custom house.
About 1864 a friend called Delpino’s atten-
tion to the account of an English observer of
the manner in which a Ligurian orchid was
pollinated by Xylocopa. Delpino at once re-
plied to his friend that there should be a
similar apparatus in the flowers of the As-
clepiadacee and he hastened to Chiavari to
verify this prophecy. Here he quickly found
the Xylocopa in the act of pollinating the
flowers of a magnificent Brazilian asclepiad.
SCIENCE.
[N.S. Vou. XXT. No. 548.
The discovery of the relation between this
plant and its insect visitor was a turning point
in Delpino’s career, for the paper which he
promptly published at once put him into rela-
tions with the botanical world and marked the
beginning of a long series of brilliant re-
searches. Becoming a professional botanist,
Delpino taught successively in the universities
of Genoa, of Bologna and of Naples.
His predominant interest was always in the
relations between plants and animals, but he
made valuable researches and thought pro-
foundly on other departments of botany, at-
tacking problems as far away from his chosen
subject as phyllotaxy and plant geography.
As a university professor Delpino was prob-
ably more feared than loved by his students.
No member of the first class which took the
final examination in botany at the University
of Naples after Delpino’s assumption of the
instruction in that department will ever for-
get the wholesale manner in which the failures
were recorded. His manner, too, would im-
press one who met him for the first time as
somewhat ascetic. But an experience of al-
most ten years, of the unvarying courtesy with
which Pr’}-:ssur Delpino, in frail health and
loaded wit arches of his own, would re-
spond to every demand for an opinion leads
the writer to remember him as no less typical
an Italian gentleman than he was an ideal
scholar. J. Y. BERGEN.

THE AMERICAN MICROSCOPICAL SOCIETY.
Tue twenty-seventh annual meeting of the
American Microscopical Society will be held
at Cedar Point (Sandusky), Ohio, on July 5,
6, 7 and 8, 1905. The society will be the
guest of the Ohio Lake Laboratory under the
direction of Professor Herbert Osborn of Ohio
State University who has placed at the dis-
posal of the meeting all the facilities of the
laboratory and who is planning excursions and
collecting trips to demonstrate the rich fauna
and flora of this region. The meetings will
be held in the laboratory with the exception of
the president’s address which will be given in
Sandusky.
JUNE 30, 1905.]
The general outline of the program shows
that Wednesday morning is devoted to busi-
ness, the afternoon to the reading of papers
and the evening to the address of the retiring
president, Dr. Henry B. Ward, on ‘The Re-
lations of Animals to Disease.’ Thursday’s
program is especially devoted to medical zool-
ogy, the morning being given to papers and
the afternoon to a symposium, led by the presi-
dent, on animal parasites, their effects on the
hosts, with demonstrations of specimens and
microphotographs, and discussion. This even-
ing the society will be tendered a reception.
Friday the program includes papers and a
symposium on fresh water biology, led by Dr.
R. H. Wolcott, covering the field of limnobiol-
ogy. The evening will be spent on the beach
and Saturday will be devoted to excursions.
Summer tourist rates make Sandusky an
easy place to reach from all points, and the new
hotel, ‘The Breakers,’ which has been selected
as headquarters, insures satisfactory accom-
modations. There will be at the meeting
demonstrations of apparatus and specimens
both by firms and individuals. Persons haying
specimens or photomicrographs of parasites
and other forms which they may wish to show
can send them to headquarters in care of the
officers and they will be duly presented and
returned at the close of the meeting.
COLUMBIA UNIVERSITY AND DR. R. S.
WOODWARD.
Ar its recent commencement exercises, Co-
lumbia University conferred the degree of
doctor of science on Dr. R. S. Woodward,
formerly professor of mechanics and mathe-
matical physics, and now president of the
Carnegie Institution of Washington. He was
presented by Professor Edmund B. Wilson,
head of the department of zoology and Dr.
Woodward’s successor as dean of the faculty
of pure science, who said: “It is a rare dis-
tinction to have attained a position of com-
manding eminence at once in scientific dis-
covery, in scientific teaching, and in the direc-
tion of scientific and educational affairs. It
is my privilege to present for the honorary
degree of doctor of science one whose many-
sided achievement has written his name high
SCIENCE.
997
on the rolls of fame for all of these—Robert
Simpson Woodward, for many years the hon-
ored and beloved dean of the faculty of pure
science, and now president of the Carnegie
Institution of Washington. In a distin-
guished service of more than twenty years
under the national government, as engineer
of the lake survey, astronomer and chief
geographer of the Geological Survey and as-
sistant on the Coast and Geodetic Survey, his
varied and profound researches won for him
a secure place in the front rank of those who
have successfully grappled with the great
problems of astronomy and geophysics. For
twelve years a professor at Columbia, his work
as teacher and investigator in the fields of
mechanics and mathematical physics has of-
fered a model of lofty ideals and exacting
standards to his fellow students, whether those
whom he taught or those who taught with him.
As dean of the faculty of pure science he has
served Columbia with a conspicuous devotion,
loyalty and success that will not be forgotten.
His has been the leadership not alone of the
eminent scholar and wise counselor, but of
the trusted friend, and his example has taught
once again the lesson, greater than any in his
own large and difficult field of scholarship,
that the cause of learning may be advanced
as much by the quality of the man as by the
achievement of the man of science. As presi-
dent of the New York Academy of Sciences,
of the American Mathematical Society and
of the American Association for the Advance-
ment of Science, he has been the far-seeing
and eloquent spokesman of science to his fel-
lows. He has now been called to a place of
leadership in organized scientific inquiry for
which history can not show a parallel. Co-
lumbia bids him godspeed, and gladly pays
her tribute of honor to one whose life and
work have been an honor to her.”

‘The Bahama Islands’’ is issued as the first monograph of the Geographical
Society of Baltimore. In June, 1903, the Society equipped and sent out to the
Bahama Islands a scientific expedition under the direction of Dr. George B. Shattuck
of the Johns Hopkins University. Investigations were carried on in Geology, Paleon-
tology, Tides, Earth Magnetism, Climate, Kite-flying in the Tropics for atmospheric
observations, Agriculture, Botany, Mosquitoes, Fishes, Reptiles, Birds, Mammals,
Medical Conditions, Social Conditions, and the History of the Islands, compiled
from original records in possession of the government. The book contains chapters
on each of these subjects. The chapter on Geology is written by Dr. George B.
Shattuck of the Johns Hopkins University, and Dr. Benjamin LeRoy Miller of
Bryn Mawr College ; that on Paleontology by Dr. Wm. H. Dall, U. 8. National
Museum ; that on Tides, by L. P. Shidy, U.S. Coast and Geodetic Survey, and so on.

‘«That the Geographical Society of Baltimore should have had the public spirit and the wisdom to
devote its resources to an object of such permanent value and usefulness is a matter for hearty congratu-
lation, Its course in this respect should be made an example for like societies elsewhere, for this book on
the Bahamas will be of lasting value when popular lectures by distinguished travelers are forgotten. It is
not too much to say that this first monograph of the Baltimore society is the most complete which has ever
been written on the subject, and that it will be for a long time to come the standard reference authority on
the Bahamas. The work has not suffered at the hands of the publishers. It is in every way an admirable
piece of scientific book work. —The Philadelphia Ledger.

JOURNAL OF PEDAGOGY
ESTABLISHED IN _ 1887
An Educational Magazine of interest to all serious students of education.
Some of the ablest contributions now being made to educational
literature are appearing in the JourNnaL oF PEpacocy.
A REPRESENTATIVE OPINION
“Tn building up the occupation ot teaching till it becomes a true profession,
no magazine is rendering more significant and vital service than the JOURNAL
oF PEDAGOGY, which admirably displays the interest of the editor in the science
and art of education. Its articles have always been noteworthy for their
strength and freshness; its book reviews have been conspicuously valuable,
exceeding in number those of the several other leading magazines combined.
No field of educational effort has been neglected ; and there has been a reason-
able apportionment of space alike to the university, the high school, the
elementary school, and the kindergarten. Those who are earnest for the better-
ment of American education view with the greatest seriousness the endeavor
of such a magazine as the JOURNAL OF PEDAGOGY to represent the best thought
and practice of the times, and by representing that thought and practice to
encourage their influence. To publish such a periodical is a noble PE ng
for the welfare of American schools and of the American nation.’’—Dr. W.
Chancellor, Superintendent of Schools, Paterson, N. J.
