Show HORSE DOES NOT REASON. His Ability Lies in His "Wonderful Power of Observation. BERLIN. Dec. 10. Dr. Carl Stumpf, professor of physiology at tho University of Borlln and a member of tho Royal Academy of Sclenco, and two colleagues, Dr. C. Von Hornbostel and ' Dr. O. Ffungst havo ended months of experiments experi-ments with Von Ostcn's horso, Hans. They find that tho secrot of tho animal's replies is in his powers of observation, which enable him to percclvo whllo ho looks at his questioner tho instant ho has reached a correct answer. Thus they found tho horso was unablo to tap out a correct answer to a question when tho person putting it did not know tho answer, for oxamplo, how many persons per-sons aro In the croup behind mo, tho questioner did not look behind and Hans did not givo a correct reply, nor was ho ablo when wearing blinkers to perform tho simplest counting. Stumpf doos not doubt tho good faith of Von Ostcn, but ho concluded that tho horso's long training had taught him to detect tho oyoslght changes In tho bearing bear-ing of hla questioner as ho reached tho right number of hoof beats In spoiling or in using tho counting apparatus. This sharpness of observation In ltsolf is mo3t remarkable, as tho horso notes movements move-ments or changes In expression invlslblo to others and of which tho questioner Is unconscious. This conception of tho horso's abilities is tho only ono to cover all circumstances. Dr. Stumpf says ho talked with the naturalist about this and Shillings agreed with him. |
