of the meeting, but the session will be especially notable because it will be marked by the first of a series of
conferences which will cover systematically the broad subject of the impact of science on human beings as members of society and as individuals.” Even before the sessions opened, announcement was made by the Geographical Society of discoveries made through the observation of the sun’s eclipse June 8, 1937. The centerpiece of its exhibit ‘at Murat Temple is an oil painting of the eclipse, done by Charles Bittinger, Washington artist-scientist. It was painted in order to depict the beauty of the eclipse better than a photograph could do, and to record accurately for study the colars and appearance of the sun during the eclipse. It was completed only a week ago and this is its first showing. The National Geographic SocietyUnited States Navy expedition, which studied the eclipse last summer, traveled nearly 5000 miles to
tiny Canton Island in the Pacific
Ocean. The society said that data was gathered about the qualities of the light of the corona, composed: of nebulous matter surrounding the sun for a depth of several million miles and visible only. ‘during an eclipse. ; There are to be group meetings in the Lincoln, Claypool, Antlers,
Mexican Quake Centered Sixty Miles at Sea
By Science Service WASHINGTON, Dec. 27.—Mexico City’s Christmas Eve earthquake had its epicenter, or point of greatest disturbance, 300 miles away from the city and 60 miles at sea, off the coast of the southern state of Oaxaca, U. S. Coast and Geodetic Survey scientists determined today after examination of data collected telegraphically by Science Service. The epicenter was in latitude 15.5 degrees north, longitude 99 degrees west. The shock, which the seismologists described as “very strong,” occurred at 7:179 a. m. (Indianapolis Time) on Thursday, Dec. 23. Stations reporting were those of the University of California, the University of Michigan, Georgetown University, Fordham, University, the Dominion Observatory at Ottawa, the experimental station of the U. 8. Coast and Geodetic Survey at Washington; Survey stations at Tucson, Ariz, San Juan, P. R, Ukiah, Cal.; Dominion Meteorological Observatory, and Williams College. =
6 CENTURIES OF SYRIAN PAINTING ARE DISCOVERED
Unearthing to Be Announced ~~ At Meeting in Ithaca ~ By Dr. Waage.
By Science Serviee ITHACA, N. Y,, Dec. 27.—A complete history “of painting from the first to the sixth centuries after Christ has been discovered through
excavation of a unique series of mosaic floors in houses in Antioch, Syria, and will be announced at the annual meeting here the Archaeo-
logical Institute of America at}.
Philadelphia, by Dr. F. O. Waage of the Department of Classics of Cornell University. Dr. Waage will exhibit for the first time photographs of the remarkable mosaics which were copies of long-since destroyed paintings of early masters. Executed with remarkable craftsmanship, the mosaics retain the original color effects of the variegated bits of limestone, terra cotta and glass
which were used in their design.

Experiments in Radiation
Shown in Exhibit (Copyright. 1937. by Science Service) An exhibit showing how scientist-
explorers venture into the “no man’s land” of radiation is a feature of the American Association for the Advancement of Science exhibit at the Murat Temple. Science has explored well the spread of radiation which runs from cosmic, radium and X-rays at one end to the radio waves at the other. Visible - light is only one tiny portion of these great light spectra. But there is one unexplored “no man’s land.” ‘The “no man’s land” region of radiation is that portion of the spectrum lying between infra-red rays and the shortest of radio waves. The exhibit prepared by Prof. H. M. Randall, University of Michigan, shows the devices by which physicists study the behavior of light in this “darkest continent” of radiation waves. Prof. Randall, from a lifetime of study, has assembled for his exhibit strange’ and little-seen equipment used to generate and detect the rays. This radiation is a cross between heat rays and radio waves. It will pierce layers of black paper and appreciable thicknesses of hard rubber. Ordinary receivers like photo-electric cells and common thermopiles will not detect its presence. Radio receivers are-also useless. : La Rock Salt Crystals Used * Crystals of rock salt, rather than
glass, must be used to’ bend ‘the far infrared rays in studies of its prop-
‘erties. Grating lines scratched on
stals are also used. ae of the radiation which comprises “no man’s land” is the energy ° ‘released by molecules as their vibrate like two or more balls at ends of a spring. In the remote region of the far infra-red, even the minute amount of energy released as the atoms in the molecule rotate, one about the other like a spinning dumbbell, is responsible for radiation. The National Geographic Society presents an exhibit that will take the layman to the eclipse of the sun which occurred in the faraway South Seas last June 8. Special cameras and instruments used in studying the sun’s flaming surface during the Hesiing = moments of the eclipse are heing shown. From Indiana University comes the exhibit of Prof. A. C. Kinsey which gives the layman a peek. at one of the world’s greatest insect collections of more than 5,000,000 specimens. Prof. Kinsey is exhibiting special mountings of galls and gall wasps which have been collected over 20 years in the United States, Mexico and Guatemala. _ This collection is of outstanding use of entomologists, ‘because, through it can be traced the process of evolution in insects, the alteration of generations, and the producue of offspring by unmated fees.
Upper Air Currents To Be Discussed Latest developments in investiga-
tions of upper air currents, vital to
aviation, will be disclosed at ses-
sions of the American Meteorological |
Society, meeting here this week.
_ The group will convene in connec-

of the principal spskers.
Dr. J. E. Janney of Western College, Oxford, O., told the psychology section of the Association today. He reported on the results of a survey of women college students, particularly the athletic type, which he said “has been vastly misrepresented.” Other papers presented today. included announcement of a new method of identifying the drug marijuana; a new substance 100 times more deadly for killing rats, but not dangerous for humans, and a chemical taken from yeast cells Which aids in healing burns.
Have More Women Friends
‘Dr. Janney said that “women athletes have more women friends and receive higher grades than their less proficient colleagues.” They also are the equals of girls not interested in athletics “in the attention received from men,” he said. They are “modest and inclined to underestimate rather. than overestimate their ;abilities and charms,” he concluded. Dr. Arno Viehover, Philadelphia College of Pharmacy, announced the discovery that the minute water flea can be, utilized in-the identification of marijuana, a narcotic whose use, especially among the younger generation, has increased rapidly in the last decade. - A-small amount of marijuana dissolved in chemicals will result in immediate death of the water flea, Dr. Viehover reported. He also said the flea can be used in identifying other poisons by the reactions of nerves and glands as revealed by a microscope. The new powerful rat poison was announced by Prof. Floyd J. Le Blane, South Dakota State College, and Dr. C. O. Lee, Purdue University. It is an extract of red squill, a plant found on the shore of the Mediterranean Sea, and has not yet been isolated completely. Its discoverers predicted it will kill “the largest rat” easily and ‘not be harmful to humans. The burn-healing chemical, as yet unnamed, was reported by: George Sperry Sperti, Elton Cook, John R.
Andre Ceuto and has been in use at St. Mary’s Hospital in Cincinnati. The chemical is a watery fuid from injured yeast cells which is said to grow new skin over burned flesh without: leaving ugly, drawn scars. Mixed With Salt Solution Yeast is mixed with a salt solution and then subjected to ultra-violet rays for approximately an hour until the cells are injured badly. The liquid then is filtered. In the filter is the unnamed fluid which the ournhealing properties. * The discoverers reported that ovis dently injured cells within themSelves will make new healing chemicals. Possibility of a new and potent means for combating parasitic worms of human beings and animals is suggested by a report presented by Conrado F. Asenjo, School ol ial Medicine, San Juan, R. In the milky juice, or latex, of Te creeping fig, Mr. Asenjo found a protein substance that attacks the parasites, literally digesting the skins off them. Concentrations as
low as 3% of 1 per cent were f effective, he said. sung

of insanity, the A. A. A s. was told today. Drs. Walter L. Beruetsch and Max
1 Bahr, Indianapolis, said they had
determined existence of the relationship during study of 84 cases of dementia praecox. In many of the cases, they said, rheumatism was an important contributing factor to the mental ills.
They said nnoe of the cases they had observed had been treated for rheumatism, which heretofore had been blamed only for attacks on the muscles, heart and joints. “The rheumatic affliction of the brain which caused mental breakdowns was not suspected and was not recognized while the patient was living,” they said. ¥ Microscopic studies showed that 8 per cent of the mental patients had rhzumatism of the brain as well as the heart, they said. All dementia. praecox patients with rheymatism of the heart also had rheuthatism of the brain. Dementia praecox forms about 20 per cent of ‘mental cases. The doctors stressed that their investigations do not mean that every person with rheumatism will have heart disease or mental affliction. The study indicates only that in many instances mental trouble results from . the disease,

Tooth Decay .Blamed On Pilot Biscuit By Science Service NEW YORK, Dec. 27.—Pilot bis-
cuit or ship’s biscuit, one of the oldest of white man’s foods and one which he took around the world on his voyages of discovery and conquest and gave freely to the natives he encountered, today is blamed for causing the most widespread type of tooth decay. Investigations leading to the tentative conclusion that pilot biscuit or similar compact starch food is a primary cause of tooth decay are reported. by Dr. Theodore Rosebury of Columbia University College of Physicians and Surgeons in an announcement from the University here today.
- Dr. Rosebury’s conclusions upset the theory that soft foods are bad for the: teeth. Explaining his new theory of tooth desay being caused by pilot biscuit or similar food, Dr. Rosebury states:
“When eaten, particles of such food are packed into the fissures of teeth under relatively strong biting pressure, and are not subsequently removed in the process ‘of eating. The particles ferment and the acids produced attack the tooth structure, causing cavities in accordance with the classical theory of dental caries.
“Other food such as bread, orl
toast, which may be hard but is not compact, and crumbles under biting pressure without packing, does not come within the same classification. “ “The hypothesis, that this one class of food is a primary cause of tooth decay, must await clinical tests with human beings before it can be finally accepted.”
