were reported upon the bacteria present in cans of coin which had become spoiled 

 and "swelled." The cause of the trouble was found to be the presence of certain 

 species of bacilli which resisted the temperature used in canning the corn. The same 

 bacilli were found ujjou the fresh corn and husks. 



Food requirements in winter and summer in temperate climates, K. E. 

 Ranke {Ztschr. Biol., 40 {1900), No. 3, pp. 288-323, dgms. ii).— Experimental inves- 

 tigations are reported in which the composition of food was determined as well as 

 the amount of water consumed, and that excreted in the urine and feces, in winter 

 and summer. The author's deductions follow: Above 16° C. there is no diminution 

 in the amount of food required corresponding to the temperature. Physiologically 

 active temperatures, which must exceed 20°, diminish markedly the appetite and 

 therefore the food consumed, an effect which pertains more to pathology than to 

 physiology. If large amounts are eaten contrary to the demands of the appetite, the 

 pathological conditions become more marked.
