these organs, and consequent irritation, poisoning, and diarrhea. 

 They further weaken the system so that it can no longer resist and 

 overcome the trouble. 



The condition of the nursing cow and her milk is another potent 

 cause of trouble. The food of the cow is important. The influence 

 of this is shown in the following tables : 



Becqiierel and Vernois. 



In these examples the deterioration of the milk in casein on the less 

 nutritious winter feeding is very marked, although the relative 

 amount of butter remains almost unchanged. In the case of the goat 

 the result is even more striking, the beet diet giving a very large de- 

 crease of both casein and butter and an increase of milk sugar. 



The following table, condensed from the Iowa Agricultural Ex- 

 periment Station Bulletin, gives the results in butter and total solids 

 when the same cows were fed on different rations in succession. Each 

 cow was fed a daily ration of 12 pounds corn fodder and 4 pounds 

 clover hay, besides the test diet of (1) 12^ pounds com-and-cob meal, 

 and (2) 10 pounds sugar meal — a product of the glucose manufacture. 

 This special feed was given seven days before the commencement of 

 each test period to obviate the effects of transition. The analyses 

 of the special rations are given below:
