These almost incredibly large figures illustrate much the 

 same points, particularly the rapid multiplication at blood- 

 heat, and the later rise at '/y'^ C. 



The Influence of Time is not less marked than that of 

 temperature, as the following table will show : 



(Conn.) 

 Freudenreich gives another example, as follows : 



Milk drawn at 15.5° C. = 27,000 m.o. per cc. 



After 4 hours = 34,000 " *' " 



" 9 " = 100,000 " " " 



" 24 " = 4,000,000 " " " 



Concerning these figures little comment is necessary. 

 But here again, we may remember that this rapid multipli- 

 cation continues only up to a certain point, after which 

 competition brings about a marked reduction. 



The effect of temperature and time has been illustrated 

 by Dr. Buchanan Young's recent researches, laid before the
