CREAM. 



WHEN milk as drawn from the cow is allowed to 

 stand, there is immediately a change in the relative 

 position of the milk-globules in the fluid. These 

 globules, so fine as to be in a state of equilibrium in 

 the fluid, or whose specific gravity differs so slightly 

 from the fluid in which they are suspended that their 

 position remains practically unchanged, retain their 

 distribution, and, after a time, become a constituent 

 of the skim-milk. The remainder of the globules 

 seek the surface of the milk to form cream, with 

 a rapidity proportional to their separate specific 

 gravities. 



On account of the differences in the size and spe- 

 cific gravity of these globules, there is a tendency 

 towards an arrangement of the cream in layers, the 

 largest spheroids being at or near the surface, the 

 smallest against the under side of the cream. In 

 consequence of this arrangement, we find in cream 

 an uneven product, as it is formed on the milk, each 

 layer presenting a different-sized globule, and coiise-
