counts. No cells of a type different from those found in later stages 

 of lactation were found in the colostral milk. 



Chloe B. (No. 7). — -The first cow studied was Chloe B. She was 

 a grade Jersey, five years old and had always calved normally. 

 At the end of the lactation period just previous to the one studied, 

 she developed an abscess between the forward quarters of her udder 

 which healed and formed a bunch between these quarters several 

 inches long. This was gradually absorbed but was still two or three 

 inches in diameter at the time she calved in March, 1911. Her 

 calf was born during the night of March 2, was a normal calf, and 

 soon began to take his share of the milk. Samples of mixed milk 

 were taken from the pail at each milking, but inasmuch as the calf 

 took part of the milk until the evening of March 7, the samples taken 

 before this date do not represent a sample of the entire milking. 

 Samples of milk were taken from single streams of each quarter of 

 the udder beginning with the evening of March 4. As shown in 

 Table VIII, these samples were taken either from the first stream 

 drawn, or when the milking was approximately half done, or from 

 the strippings. Samples of the foremilk, middlemilk and strippings 

 were taken from the evening milkings only.
