CLASSIFICATION OF SPECIMENS OF FISH BY AMOUNTS OF WATER- 

 FREE SUBSTANCE IN THE FLESH. 



The kinds of fish analyzed are grouped below on the basis of the per- 

 centages of water-free substance in the rfesh. The specimens are 

 ranged in order from those with the largest to those with the smallest 

 amounts of water-free substance. Of course those with the most water- 

 free substance have the least water, and vice versa. Hence, the first in 

 this arrangement have the lowest percentages of water, while the last 

 are the most watery.
