 OR THE MISSING LINk''
Discussed by the American ~Associa- ton for the Advancement of Science

New York, Dec. 2S.-A machine that shows how sound looks." a restored 'pithecanthropus erectus" who roam ed the earth 500.000 years ago as the missing hnk." a discussion as to nent 125.O00 years or 100000 and many addresses on modern economic and humanitarian subjects made up the interest at the various sessions of the American Association for the Ad- vancement of Science here today.
 Machine to Measure Sound.
 The sound machine. which is called the "phonodeik,'' was exhibited by Professor Dayton e. Miller of the Case School of Applied Science, Cleve- strument photographs the vibrations of the human diaphragm governing the volume and cadences of the voice and projects them, magnif1ed 10000 times, on @ screen.
 Record of Sound.
 Then Professor Miller spoke the word war" into the machine and a confused irregular blot of light fash ed upon the scene. Pronunciation of peace" produced in marked contrast a mild glow regularly and delicately outlined. A record of Caruso's voice caused a broad, violently f1uctuating line of light, while Tetrazzini's voice showed as a finely pencilled dancing path of light. A record of the sex tette from Lucia showed the indiud- ual characteristics of the singers in
 5o0,ooo Year Old instrument.
 The 500.00o year old pithecanthro- pus erectus was introduced to modern society by Professor James A Me Gregor of the department of zoology, Columbia University. He explained that the habitat of 'P. E.'' as he was called for brevity, was Java. Virtual, ly all there is of the original 'ape man" Is the skull and jawbone. The restored figure was declared by Pro- lessor McGregor to be an accurate reproduction of mans Darwinian an- cestor.
 Antiquity of Man in North America.
 The discussion as to the antiquity Of man in North America before the American Anthropological Association revolved around human remains and other objects recently found at Vero, Florida. Dr. Ales Hrdlicka, curator of anthropology at the United States Naval Museum. Washington, D. C., pr. o. R. Hay of the Carnegie Insti- tuition of Washington, contended that the evidence showed men lived here no less than 300,000 years back. He took part in the excavation of the find and said that among the rem nants of animals found were bones of a ground slotha as big as an elephant.
 New Science of Humanity.
 How the United States Steel Cor poration has spent $5,500,9 900 on the new science of humanity in reduc- ing the number of accidents 1854 per cent, and saving 4,967 men was told by Charles l.. Close, manager of the corporations bureau of safety, sani- tation and welfare work Such work hay progressed to such a degree, he said, that it now deserves to be called a science.
 "Judeing Impulses"
 In the psychological division of the convention which demonstrated an electric apparatus for Judging inn pulses," the inventor claimed that by its aid one can 'rteu what his patient will do next" There was also shown a magic mirror" for measuring men talities."
 Why Men and Women Borrow.
 Why men and women borrow was shown in a statement by Clark Will Hams, president of the Industrial Fi- nance Corporation Morris Plan." He said $50 borrowed to repay '1oan sharks" or to redeem pawns, 4,182 because of illness or births, 399 be- cause of deaths. 29S for weddings, 56S for education, 2,622 for business ex- penses and 1900 to pay mortgage in- terest. taxes and rent.
