47. (pp. 73, 75). The literature concerning bacteria in their relation to temperature i: 



enormous, since almost every work dealing with a new species describes it: 

 behaviour to heat. The foundations of our knowledge of the subject were laic 

 by COHN (Untersuch. ii. Bakterien iv, in Beitr. z. Biol. vol. ii, 1876). He basec 

 his work on that of the older investigators in physiology and the problem o 

 spontaneous generation, and showed first that the spores of the hay-bacillu: 

 resisted boiling. Robert Koch introduced the methods and results of plan 

 physiology into medical bacteriology, Beitr. z. Biol. vol. ii.

50. (p. 77). Experiments innumerable have been made on the power of bacteria to resis 



desiccation ; here again the fundamental facts were given by Cohn in thi 

 Beitr. z. Biol. ; see also Eidam, Die Einwirkung verschiedener Temperaturei
