JPms ; Pus corpuscles in milk appear as pale globular bodies of 

 varying size. They possess a slightly granulated surface, which 

 disappears on addition of acetic acid, while the corpuscles get con- 

 siderably enlarged. 



Pus corpuscles and epithelial cells. 



EpWielial cells are found in milk but rarely, and then, per- 

 haps, accidentally. 



Lower organisms : The presence of fungi in milk can be de- 

 tected with the naked eye only when they are grouped together in 

 one place in dense masses. They have received considerable atten- 

 tion of late. It is, therefore, indicated to determine whether, in 

 the dairy industry, they are of equal importance as we know them 

 to be in other industries. The development of fungi is generally 

 a very complicated process, embracing a cyclus of the most hetero- 

 geneous shapes. Moreover, these various forms depend for their
