772 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
mum and minimum percentages of each constituent and the averages 
of all the analyses are given. 
Table 31 gives corresponding analyses of the flesh of preserved fish. 
The percentage of salt, sodium chloride, is usually given separately, 
though in some cases the analyst reported the two together, and in con- 
sequence no distinction is made here. 
Table 32 gives the percentages of proximate ingredients as directly 
determined. I have regarded it as worth while to put these analyses 
together, though, as was stated in discussing the subject in the previous 
chapters, the methods of analysis are incomplete and the results not 
entirely satisfactory. It is to be further noted that the American 
analyses were all made of the flesh freed from skin, while part, and I 
presume nearly all, of the specimens of the European analyses included 
both flesh and skin. In some if not all of the European analyses the 
insoluble albuminoids were determined by difference. 
So few of the reports of European analyses include statements of the 
composition of the fish as found in the markets, including both flesh 
and refuse matters, that a table summarizing the European and Ameri- 
can analyses on this basis, as was done with the American analyses in 
Table 9, seems hardly necessary here, especially as such a compilation 
is to be given in one of the chapters beyond (Part II) on the economic 
application of the analyses. 
Table 30. — Recapitulation of analyses of flesh of specimens of American and European 
fishes. 
[ “Albuminoids, ” etc., estimated by difference. “ Protein ” estimated by multiplying nitrogen by 
6.25. By “ maximum ” and “ minimum ” are to be understood, in each case, the largest and smallest 
percentages of each ingredient found in any of the specimens of the species.]
