A Ch'aphic Represmtation of the Bacterial Flora of Udders Nos. 1 to 6. 



The areas designated by the letters A, B, C, indicate the three arbitrary- 

 divisions into which the gland was divided for purposes of examination. A fig- 

 ure (1, 2, or 3) in the canal of the teat indicates that a culture of the micrococcus 

 bearing that number was isolated from a sample of tlie fore milk. Figures else- 

 where indicate that either a pure culture of the species in question was obtained 

 from the plaoe indicated or that colonies of that species were recognized from 

 peculiarities of growth. One-quarter only of udders Nos. 2, 3, 4 and 5, three of 

 No. 6 and four of No. 7 were examined.
