DESCRIPTION OF TABLES. 
The main results of the investigation are expressed in the tables which 
follow. : 
Table I states the results of analyses of fifty-one samples of fish, in 
the terms commonly current in such investigations. 
Table II recapitulates the analyses of Table I in such way as to set 
forth more fully the actual composition of the samples analyzed. , 
Table III recapitulates the composition of several samples on a some- 
what different basis, the essential difference being in the method of esti-. 
mating the amounts of albuminoids. 
Table IV gives a brief résumé of the composition of the samples in 
forms more convenient for reference.
