National Academy Of Science Hiolds Final Ses Group Hears 13 Papers At Final Session Seven Faculty Members Speak On Program On Last Day Of Meeting With yesterday morning's session in Lydia Mendelssohn Theatre, the 1932 autumnal session of the Na-. tional Academy of Science came to a close. Members of the Academy, who include most of the nation's foremost scientists, have disbanded, and the many lectures and reports made by them during the past three days now belong to history. Thirteen short lectures were de- livered yesterday morning, six of them by members of the faculty of the University. The graphic story of the unearth- ing of the primitive skeleton known as "Minnesota Pleistocene Homo," as told by Dr. Albert E. Jenks, of the I-University of Minnesota, was afat ure of the morning's program. Dr. Frank Leverett of the geology de- partment augmented Dr. Jenks' paper with a brief discussion of the prob- able age of the fossil man, as shown by geological studies. SOther talks covered various aspects of geology, anthropology, psychology, biology, and neurology. George O. Sqtier, Preston E. James Dr. George O. Squier opened the Wednesday session with a brief re- port on Senate Bill 2,778, relating to patent rights. The first scientific discussion was given by Prof. Preston E. James of the geography department on the surface configuration of a part of Southeastern Brazil. Frank Leverett Dr. Leverett, formerly with the U. S. Geological Survey, and at pres- ent a resident of Ann Arbor, gave a new interpretation of drainage shift- ings in Ohio, based on the eight years of study he has made since first an- pouncing the results of his field ex- cursions in the Ohio region. He pointed out that much of Ohio drained into Lake Erie during the preglacial era, and that early glacia- tion did not alter this arrangement radically. Not until the Illinoisan glaciation, 150,000 years ago, did the topography of Ohio assume its pres- ent form, with most of its rivers draining into the Ohio and Missis- sippi river system, Dr. Leverett said. Albert E. Jenks One of the most perfect and most complete specimens of fossil man ever discovered is the skeleton found in June, 1931, in northern Minnesota, described for the academy by Dr. Jenks. It was dug up by a road crew laying drainage tiles, about two feet beneath the road surface and almost 10 feet below the present surface of the ground, the road passing through cut at that point. Further diggings disclosed about 350 additional parts, -.d geological analysis of the silt proving that the body must have come to rest at the bottom of an extinct glacial lake at that spot 20,000 years ago. A hole in the skeleton has led Minnesota scientists to believe that she, for the skeleton is evidently that of a young woman, Dr. Jenks stated, was shot. From this they have con- structed a possible story of the event. Nathaniel Kleitman Dr. Nathaniel Kleitman, of the Uni- versity of Chicago, who spoke next, told of tests of diurnal variation of efficiency he has been conducting. By requiring his subjects to do certain tasks at five different hours during the day, he learned that efficiency, varies directly as the body tempera- ture. Both are lowest at about three or four o'clock in the morning, he has found, the time when it is hard- est to keep awake. The height of efficiency comes at some time in the afternoon, varying according to the individual. These diurnal variations are found to correspond regularly to! the body temperatures, and occur at a regular time of day, regardless of the amount of sleep the subject may have had, Dr. Kleitman concluded.

Weller "One must conclude that the pro- tective mechanisms found in the my- ocardium are of biological signifi- cance and that they have been devel- oped and perpetuated in order to maintain, in so far as possible, the integrity of the myocardium, so es- sential for the perservation of the organism," Dr. Carl V. Weler, direc- tor of the University 'pathological laboratories, told the audience, enum- erating a number of the protective features he had in mind. John F. Shepard. Dr. John F. Shepard of the psy- chology department presented draw- ings of several of his rat mazes upon the screen and explained the tests to which the rats were put. Two of the rodents with which he had ex- perimented successfully passed every test, he said, while the others fell by the wayside as the trials became more difficult. The tests prove that some rats can tell the right way through a maze by the sound of their feet on the floor, while in others this sense is not so strong, he explained. sion Of Conference Prof. Roy Holmes Begins Work On Cultural History Of Michigan Hunt Perfects Instrument For Mineralogists Measures Proportion Of Materials In Rocks; Siu- plifies Study Prof. Walter F. Hunt, of the Min- eralogy department, in 'conjunction with Prof. C. K. Wentworth, of George Washington University, has recently perfected a measuring gauge that greatly simplifies the study of a given rock to determine the amount and proportion of materials in it. Until now one of the most wearisome problems facing the mineralogist, the study has been simplified so as to re- quire about one-fifth of the time heretofore needed. The make-up of the rock must be frequent determined by the mineral- ogist. To do so he cuts out a sec- tion thin enough to be translucent and mounts, it on a miscroscope lide. He then mounted a screen of known dimensions under the slide adcomputed one at a time the amount of feldspar, mica, quartz, and other rock crystals scattered in the sample. It was a laborious and eye- straining process. With the new apparatus a plat- form bearing the specimen slide is moved across the line of vision, driven by five dial-marked screw grips. By giving one dial to each of five crystals and by reading off each dial the size of the crystal as meas- ured by the turns required to bring it across the sample, the five com- ponent mineral crystals may be read straight across the specimens at one time. The dials register to one-five- thousandth of a millimeter. As one millimeter is about four-one-hun- dredths of an inch, quick and accu- rate computations are easily made. are surprisingly accurate is the con- clusion he arrives at after careful comparison with other records. The chronological table is based on a per- iod of 11,960 days, or 405 lunar months. For a number of years students in rural sociology have struggled with textbooks and theories, and, after several weeks' work in the library, they have written term theses, filled with facts and statistics copied from the pges of authoritative books. This year Roy H. Holmes, profes- sor of rural sociology, has conceived a new and more practical idea for the study of rural problems by bring- ing the students in actual contact with -the members of rural commou- nities. The purpose of the new study is to furnish more up-to-date informa- tion for class work, in making a thorough study of rural Michigan both past and present. Through rep- resentatives which are to be located in every township in the state, ma- terial will be gathered. Professor Holmes aims to develop a complete cultural history of the state, show- ing group tendencies through the generations since the first settlement. 'It will be largely a sudy of leader< ship, taking into account the work of Michigan's p i o n e e r s," Professor- Holmes said. The completion of the task will take about 10 years, Professor Holmes explained. The work of the students will contribute in part to the gigantic, project with the results of their 1in1 vestigations. Foreign graduate stu- detns are making studies of their na- tive countries. At the end of the complete study; Professor Holmes expects to write a book which will be entitled, "Social History of Rural Michigan. Profes- sor Holmes has already written a book, "Rural Sociology," which has. been adopted for class use by a num- ber of universities. 1.. - 3.DAY SPECIAL THURSDAY, FRIDAY and SATURDAY 5 P.
