CALVES SLAUGHTERED 18 HOURS AFTER EATING. 



Average : Air dry, 1 part rennet to 23058 parts milk, 

 free, 1 part rennet to 25338 parts milk. 



CALVES slaughtered 30 HOURS AFTER EATING. 



Water 



Average : Air-dry, 1 part rennet to 12850 parts railk. Water 

 free, 1 part rennet to 14261 parts milk. 



These results indicate a progressive increase in the strength of the 

 rennet due to fasting in the three classes from one hour up to eigh- 

 teen. The average number of parts of milk curdled by one part of 

 water free rennet is : after one hour's fast, 22,091 ; after five hours, 

 23,315, and after eighteen hours, 25,338. The number of animals 

 fasted thirty hours is too small to justify any comparison. The 

 average for one part of water free rennet is 14,261 parts of milk. 

 This though smaller than any other average is larger than the average 

 of the first two animals in the first class and does not differ very 

 materiully from similar averages in the other two classes. We are 

 not, therefore, justified in concluding that a fast of thirty hours is 

 prejudicial to the strength of rennets.
