[27] CHEMICAL COMPOSITION AND VALUE OF FISH FOR FOOD. 257 
striped bass, porgy, and flounders end the list with the largest waste and 
_least flesh of all. It is, of course, to be understood that the variations 
in individual samples of the same fish are so wide as to make a much 
larger number of determinations necessary to give us fair averages and 
allow satisfactory generalizations. 
The proportions not only of flesh, but also of water and solids in the 
flesh differ widely in the different samples, as will be seen in the tables. 
Thus, in the third and fourth columns of Table II we find that the flesh 
in the samples of flounder contained from 83 per cent. to 85 per cent. of 
water, and only from 17 per cent. to 15 per cent. of dry substance, sol- 
ids; while in the fat shad, mackerel, and salmon we have from 65 per 
cent. to 63 per cent. of water, and from 35 per cent. to 37 per cent. of dry 
substance. Below the samples of fish are arranged in the order of their 
percentages of dry substance in flesh. 
Proportion of dry substance in flesh, edible portion.
