170 ORGANISED FLUIDS. 



The number of globules contained in the milk of different 

 animals doubtless varies considerably ; but there is as much 

 variation in this respect as in those just referred to ; and, 

 therefore, this difference is not sufficient to distinguish the 

 several kinds of milk. 







RELATIVE PROPORTIONS OF THE ELEMENTS OF MILK. 



Chemical analysis indicates a very great variety in the 

 relative proportions of the different nutritive ingredients of 

 milk ; and this, not merely with respect to the milk of dif- 

 ferent animals, but also in reference to that of the same 

 species, and even of the same individual, at different times. 



The truth of these remarks will be evident from an ex- 

 amination of the following analyses :
