Besides the analyses above mentioned, others have been reported, but 
none with which I am familiar have been executed by methods making 
them comparable with these, or to give definite information as to the 
amounts of the constituents now recognized as making up the tissues 
of the fish. I may, however, refer to a number of earlier analyses. 
One of these is Exarnen Chimique de Veperlan , jSdlmo eperlanus , Morin. # 
This is a qualitative investigation of some of the constituents of the flesh 
of the smelt, of which a resume may be found in Pereira (Food and Diet, 
New York, 1851, p. 132). 
Braude’s Manual of Chemistry, quoted by Pereira (loc. cit., p. Ill), 
gives the composition of the muscles of various animals, including cod, 
haddock, and sole, but regards the nutritive matter (water- free sub- 
stance) as ms ; ue up of albumen or fibriu aud gelatin, exclusively, and 
takes no account of the fat or other ingredients. 
Schlossberger t gives the composition of the muscular flesh of carp 
and trout, with that of other animals. His table is quoted by Pereira 
along with that of Braude iust named. No account is taken of the fats. 
The analysis of Leuciscus rutihis by Limprichtf will be referred to
