=Photographing Papuan Children.=--Many savages dislike to have their

pictures taken, some being restrained by motives of superstition; but

in New Guinea Professor Semon found being photographed a great joke

for all the boys and girls. He had much trouble in isolating a single

individual, so as not to get thirty or forty persons into his picture

instead of the one he wished to immortalize. "Wishing," he says, "to

portray one young girl of uncommonly good looks, I separated her from

the rest, gave her a favorable position, and adjusted the lens,

surrounded all the while by a crowd of people behind and beside me,

the children cheering, the women most ardently attentive, the men

benevolently smiling. Evidently my subject was proud of the

distinction she enjoyed and the attention vouchsafed her. Quite

suddenly, however, this simple savage, untaught as she was and

innocent of the laws of reticence and prudishness, became convulsed

with shame, covered her eyes with her hands, and valiantly resisted

every attempt to make her stand forward as before. At the same time I

noticed that the hue of her features changed, the brown of her face

becoming darker and deeper than before, a phenomenon easily explained

by the fact of the blood rising into her head. Had she been a brown

girl we would have said that she blushed. At all events, the

physiological process was the same as that which forces us to blush."

At another time, when the author had got two little girls into

position to be photographed, their mothers came up and forbade his

taking them that day, but promised to present them on the morrow. On

the next day "both the little angels were solemnly brought to meet us

nearly smothered in ornaments, their hair decorated with feathers and

combs, their ears with tortoise-shell pieces, their little throats

surrounded by plates of mother-of-pearl and chains of dingo teeth,

legs and arms hung with rings and shells, teeth, and all sorts of

network.... Here, again, one may see that mothers are made of the

same stuff all over the world, Papuan mammas being equal to any of our

peasant women or fine ladies in the point of vanity as far as concerns

their children."

=Meat Extracts.=--An interesting account of the history and

preparation of meat extracts was recently given as a lecture before

the Society of Arts (English) by Charles R. Valentine. The idea of

concentrating the body of an ox into a thimbleful of elixir seems to

have been a very old one. Until the work of Justus von Liebig, about

fifty years ago, however, little progress of practical value was made

toward this end. Liebig macerated finely divided beef in cold water,

or in water not above 150° F. The water dissolved from sixteen to

twenty-four per cent of the weight of the dry flesh. This infusion was

heated, the albumen and red coloring matter of the blood coagulated,

and was separated as a flocculent precipitate. The remaining solution

has the aromatic taste and all the properties of soup made by boiling

the flesh. The infusion was then evaporated at a gentle heat. The

residue amounted to about twelve or thirteen per cent of the original

(dry) flesh. This is in rough outline the process of meat-extract

making. This extract is simply an evaporated beef tea, containing the

extractive matters of beef, and in virtue of these possesses medicinal

and dietetic properties of value. But it is in no sense a substitute

for beef, as the latter's most important food constituent--albumen--it

does not contain.

It appears from tables of Some Statistics of Engineering Education,

compiled by President M. E. Wadsworth, of the Michigan College of

Mines, that such education has been, in the United States, on the

whole a thing of comparatively recent date, the oldest school, the

Rensselaer Polytechnic Institute, having been established in 1824; the

next, the Lawrence and Sheffield Schools, in 1846 and 1847; and the

Columbia School in 1863. Civil engineering has led in this country,

and has had various periods of advance, as in 1887-'88, and

depression, as in 1896-'97. Mechanical engineering progressed till

1886-'87, when the number of students fell off, and the same happened

with electrical engineering, "which further suffers a natural reaction

from having been greatly overdone." As a rule, most of the schools in

the United States seem to run to specialties, one or two of the

courses being usually more conspicuous than the others.

The importance of some arrangement by which vessels may be informed of

each other's approach in fog and darkness has given rise to many

devices; the only one, however, which has as yet proved practical is

the fog-horn or siren, and this has many disadvantages. Several fatal

collisions at sea during the past year have given rise to renewed

interest in the subject, and a number of new methods have been

suggested. M. Branley, a French physicist, in a note presented to the

French Academy suggests that each vessel be provided with a number of

extremely sensitive magnetic receivers, or coherers, and a powerful

magnetic transmitter. Periodical signals being made with the

transmitter, corresponding impressions would be made upon the

receivers of approaching vessels. The principal difficulty with this

scheme lies in the fact that the receivers of a vessel will be

affected by its own transmitter. There are several methods by which

this difficulty may be overcome, however. Different signals may be

employed, or the interval between signals may be regularly varied. M.

Branley calls attention to the influence of a metallic envelope

surrounding a coherer, and shows that when the coherer is thus

completely surrounded it is unaffected by the influence of a

transmitter. By thus inclosing the receiver on a ship at the instant

of the operation of the transmitter of the same vessel, the above

difficulty might be avoided.

While we can not collect roses from our gardens in January and maple

blossoms from the woods in February, yet, as Prof. W. J. Beal shows in

a bulletin of the Michigan Agricultural College Experiment Station,

our trees and shrubs in their winter garb furnish excellent lessons

for the profitable employment of pupils during many weeks at that

season in true botanical study. "Let each member of a class be

provided with a branch, a foot or two long, from a sugar maple, and

then spend some ten to twenty minutes or more quietly looking at the

buds and the bark, with its scars and specks, and then tell what he

has discovered, venturing to explain the object or meaning of some of

the things he has seen. In a similar manner let each look over a

branch of beech and then point out the difference between the two

kinds." Opening buds of trees may be obtained at any time during the

winter by placing the lower end of the stem in water for a week or two

while in the schoolroom.

Eivind Astrup, in his book With Peary near the Pole, gives admiring

pictures of the natural innocence of the uncontaminated Eskimos of

northern Greenland, where are communities in which "money is unknown,

and love of one's neighbor is a fundamental rule of action; where

theft is not practiced." All things are held in common, and falsehoods

are told only to spare the feelings of the listener. Among the

instances of the native kindliness of these people is one where a dog

had eaten up a reindeer coat, yet was only remonstrated with by its

owner. When the author suggested that a hungry dog should be punished

for stealing a piece of blubber, the owner said that it was himself

who deserved the thrashing for not having obtained sufficient food for

the dog.

The operations of the Illinois State Laboratory of Natural History

during 1897 and 1898 were almost wholly connected with the work of the

State Entomologist or with that of the Biological Station. The former

work related to various insects injurious to crops. The operations of

the Biological Station were carried on with more reference to

completing a formal report upon the fishes of Illinois. The work is

conducted with a view to the acquisition of correct ideas of the

relative abundance and local distribution of species, their haunts,

habits, regular migrations, and irregular movements, their building

times and places, rate of growth, food, diseases, and enemies--and, in

short, the whole economy of each kind represented at the station and

of the whole assemblage taken together as a community group. Extensive

studies of aquatic entomology were made, and a paper on ephemerids and

dragon flies is nearly ready for the press. No part of the work of the

station, however, attracts more attention among scientific men, or is

likely to lead to more interesting and important results, than the

plankton work, or the systematic study of the minute forms of plant

and animal life suspended in the water. Water analyses have been

extensively made in connection with these studies, which, combined

with the continuous biological work, will, when generalized, furnish a

substantial and authoritative body of knowledge of the conditions of

the waters of the middle Illinois previous to the opening of the

Chicago drainage canal, useful for comparison with the results of

similar studies made after that event. A summer school was conducted,

with fifteen pupils, in 1898, and publications were issued.

NOTES.

The Pasteur monument was dedicated at Lille, France, the city in which

the subject of the memorial performed his earlier more important

researches, April 9th. The ceremony was witnessed by a large assembly,

which included many eminent scientific men of France and foreign

countries, among whom men engaged in similar researches to Pasteur's

were especially represented. The monument, the fruit of a public

subscription, represents Pasteur standing on the summit of a column of

Soignies stone, holding in his right hand an experimental flask. At

the foot of the column a woman presents her child, which has been

bitten by a mad dog, for treatment. To the left is a group

representing inoculation--a woman, personifying science, injecting

serum into a child she holds on her knees. Three bas-reliefs represent

respectively Dr. Roux inoculating a sheep for anthrax, Pasteur

studying fermentation, and the first antirabic inoculation of the

young Joseph Meister, who is held by his mother, wearing the

broad-flapped Alsatian bonnet. The statue is in light bronze, and with

the gilded bas-reliefs harmonizes well with the gray of the stone.

Addresses were made by M. Armand Gautier and M. Duclaux, who said that

the improved laboratories now enjoyed by scientific institutions in

Paris were largely due to Pasteur's efforts.

The minor planet recently discovered by Witt, remarkable as having an

orbit that comes within that of Mars, and provisionally known as DQ,

has been named Eros. An examination by Professor Pickering and Mrs.

Fleming of the Harvard photographs has revealed traces of this body on

twelve plates taken in 1893 and 1894, and on four plates of 1896. By

the aid of these plates it has been possible to determine its elements

with greater accuracy than would otherwise be possible. Its mean

distance from the sun is 1.45810, its shortest distance 1.13334, and

its greatest distance 1.78286 that of the earth; the eccentricity of

its orbit is 0.222729, and its period is 643.10 days. Its synodical

period is such that it has three oppositions in seven years. The next

opposition will be in the last months of 1900, and will be a

moderately favorable one for observation.

The courses in pure science of the New York University include

undergraduate, graduate, and summer courses in mathematics, physics,

chemistry, geology, and biology, with laboratory privileges and

provision for special students and independent work in chemistry. The

university last year was attended by 1,717 students in its three

faculties and six schools, and 720 non-matriculant students and

auditors. A new feature this year is the inauguration of the Charles

F. Deems lectureship of philosophy, under an endowment of $15,000 by

the American Institute of Christian Philosophy, with Prof. James

Iverach, D. D., of the Free Church College, Aberdeen, Scotland, as the

first lecturer. A feature of the university organization is the

institution of a woman's advisory committee co-operating with the

council. A woman's law class is supported by the Woman's Legal

Education Society, the purpose of which is to make business women and

women in private life acquainted with existing law.

The new Science Building of the City Library, Springfield, Mass.,

recently completed, is being inaugurated by a Geographical and

Geological Exhibition. It includes the best and latest maps, models,

globes, charts, relief maps, and photographs, special attention being

paid to the most effective modes of teaching. One of the most

attractive features of the exhibition is the work from the Springfield

public schools.

An ingenious method for thawing out frozen water pipes has been used

by Prof. R. W. Wood, of the University of Wisconsin. It consists

simply of passing a current of electricity through the pipe. In one

case it is said that one hundred and fifty feet of frozen pipe was

thawed out in eighteen minutes. The ordinary street current was used,

the voltage being reduced to about fifty.

In a summary of inspectors' reports of the Hartford Steam Boiler

Inspection and Insurance Company for 1898 it is stated that of 78,349

boilers, inspected both internally and externally, during the year,

there were 11,727 dangerous defects discovered and 603 entire boilers

were declared unsafe for further use.

The recent death list of men known in science includes the names of

eighty-four years; Dr. G. W. Leitner, an eminent Orientalist and

linguist, Lecturer on Oriental Language at King's College, London,

Principal of Lahne College, and Registrar of Punjaub University, where

he introduced the use of their own language and literature in teaching

Indian students, founder of the Anglo-Indian Institute at Woking,

England, and author of works in Education, the Races of Turkey, The

Races and Languages of Dardistan, Græco-Buddhist Discoveries, and

other Oriental subjects, at Bonn, March 24th, in his sixty-ninth year;

Dr. Angelo Knorr, Docent in the Veterinary School of Munich, February

22d; Elizabeth Brown, astronomical observer and author of papers on
