744 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
contribution made to the knowledge of the chemical composition of the 
flesh of fish. 
(5) Analyses by Kostytscheff. — These include 31 specimens of some 24 
species. A considerable number of these, however, are of the prepared 
flesh or other parts of fish, so that, although their practical impor- 
tance is very considerable, they contribute less to our knowledge of the 
actual composition of the tissues in their natural conditions than the 
number would indicate. The same remarks apply, though in less de- 
gree, to the analyses of Almen, Konig, and Payen. 
(6) I also append the results of analyses of 2 specimens of European 
haddock made by myself in connection with the investigation on the 
digestibility of the flesh of fish reported beyond. 
The above include all the analyses of the flesh of fish made by meth- 
ods now current, which I had succeeded in finding when the present 
report was prepared. The following have since come to hand, but too 
late to be included in the tabular recapitulations. 
(7) Analyses by Popoff. — These are reported by Kostytscheff and 
include 8 specimens of fresh and salt fish and 2 of roe of apparently 4 
species. 
(8) Analyses by Sempoloivshi . — Ten specimens were analyzed including 
4 each of 7 species of fish, 1 of a crab, 1 of starfish, and 1 of oysters. 
They were chiefly for the purpose of learning the value of the materials 
for fertilizers and are of less interest here. The main results, however, 
are quoted beyond. 
In the reports of Almen and of Kostytscheff* Latin names are given. 
In the other reports, some of the names are those of species so common 
and well known as to leave little or no doubt, while other names are 
local or such as are applied to two or more species. Where the Latin 
names are not given by the analyst and are inserted by myself they are 
inclosed in brackets. In some cases the Latin names were kindly fur- 
nished by Prof. D. S. Jordan. These are indicated by “ J ” outside the 
brackets. Especially doubtful cases are indicated in the list of names 
by omission of the specific names or by an interrogation point. 
The numbers prefixed to the names in the subjoined lists are those 
employed to designate the specimens in the tabular statements and 
discussions beyond. 
NAMES OF EUROPEAN FISHES. 
Fishes analyzed by Payen . — The French names herewith are those 
given by Payen, Precis des Substances Alimentaires , 4th ed., 1865, pp. 
45 and 488. The German names are taken from a report of Payen’s 
analyses in Dingier, Polyt. Journal. 134 (1854), 385. The analyses to 
-follow are from the same sources. 
No. i. Raie, Rochem, Skate, [ Eaia , sp.]. 
No. n. Anguillede mer (Congre), Meeraal, Conger eel, Conger [ vulgaris ?]. 
No. in. Morue salee, Gesalzener Stoekfisch, Stockfish, Salt codfish (?). 
No. iv. Sardines a l’huile, Sardines, [dupea, sp. ].
