(No. 3) was tested from January 1st till April 23rd. She had 

 probably some Channel Islands blood, was six years old, had 

 calved her third calf in the last week of October, 1902, and 

 was of a quiet and docile disposition. She was milked at 

 about 6 a.m. and 4' 15 p.m. on week days, but half an hour 

 later in the afternoons during April, and on Sundays at 8 a.m. 

 and 4 p.m. She received from 5 Ib. to 81b. of cake and meal 

 daily with hay and water. She was turned out when weather 

 permitted from 9'30 a.m. till 3'30 p.m. The following table 

 shows the limits of variation of the milk of this cow :

The milk of this cow never contained less than 3'5 per cent, 

 of fat during this time, and it actually was as high one after- 

 noon as 7'8 per cent. The milk was considerably richer in 

 fat in the afternoon than in the morning, and the variations in 

 fat were greatest in the afternoon. The greatest variations 

 took place as follows : 



Thurs., Fri., Sat., Sun., Mon., 



Mar. 19. Mar. 20. Mar. 21. Mar. 22. Mar. 23.

 can be judged the weather was not accountable. The solids
