teria in theut Uterame stat. .Ini a lecture before a group of sci- entists and physicians at the McKiiù- lock campus on july 22, Dr. Kendal made tbe first announcement of the discgvery of. a new metbod f or the isolation of. bacteria wbich hitherto have remained i nvisible. This -was the development of a ' culture, medium, wbich' will change bacteria f rom in- visible to visible f orm. The discovery' was described. by colleagues of Dr. Kendall as "start-, ling as those of Pasteur," since it opened the way fora more thorough and; exact knowledge of such diseases as infantile paralysis, influenza,i-heu- matism ýand sleeping sickness. Employ Animal Tissue In- the new bulletin issued yesterday by tbe medical school, Dr. Kendall de-, scribes in detail how, the K mediums are made f rom the tissue of the animal or buman body, extracted- witb 95 per-. cent alcohol.- Intestine bas been used chiefly for this purpose, altbough Dr. Kendall points.;out that brain, liver, kidney, spleen 'and heart have been Used. "Hog intestine," lie writes, "has been distinctly more suitable than rabbit. in- testinie. and . rabbit intestine hias appeared to be more favorable than dog intestine.. Human intestine whicli wvas. fot available -%vhen, early studies were made is under investigation at present." After giving minute details of, the preparation ot the mediums and coin-' nienting upon aspects of their use, Dr. Kendall reaches the followiing conclu- sions: "TeK M.diuuis Valuable "TeK nediunis, protein rich and, peptone poor, have afforded a direct method of approacli' to the pur7view of thrîee highly important aspects.of,. bac- terioiogy which arée mutually' related; and independent? "First, (theoretical), it appears to bel abiological fact that. many bacteria can,, and do,, exist ini two states, fiter- ale and non-lfilterable. "Second, (clinical) bacteria mnay «he isolated f rom the- blood 9tream of patients suffering f rom diseases that have hitherto proved difficuit or re- f ractory to cultivation. andi rougi' types."
