356 Messrs. Schlossberger wid Kemp on the Proportion of 



poorer in nitrogen than any of the others which we have exa- 

 mined, in consequence of the large quantity of fat or oil it 

 contains; indeed, during the whole desiccation it was floating 

 in a liquid fat. ,ri x ! lu 



XVI. 0'34;5 grm. of raw eel's flesh gave 0'379'^rin»!!Qf 

 ammonio-chloride of platinum, equal to 6*91 per cent, of ni- 

 trogen. 



XVII. 0*306 grm. of boiled eel's flesh gave 0*329 grm. of 

 ammonio-chloride of platinum, equal to 6*82 per cent, of ni- 

 trogen. 



XVIII. 0*293 grm. of eel's flesh, which had been previ- 

 ously washed with distilled water and afterwards boiled in air 

 cohol as long as any matter separated, yielded 0*667 grm, 

 of ammonio-chloride of platinum, equal to 14*45 per cent, 

 of nitrogen, a quantity as great as that from the higher ani- 

 mals. 



XIX. 0'274 grm. of the flesh of the salmon, Salmo Fario, 

 gave 0*533 grm. of ammonio-chloride of platinum, equal, tp 

 12*35 per cent, of nitrogen. . ., 



XX. 0-286 grm. of boiled salmon gave 0*437 grm. of am- 

 monio-chloride of platinum, equal to 9*3[OrjJi?F cept^ tP^ PitfOt 

 gen. ro-o.'cifiti "^o .Ttioy tnj 



XXI. 0*319 grm. of the purified muscular fibre of the sal- 

 mon gave 0*785 grm. of ammonio-chloride of platinum, equal 

 to 15'62 per cent, of nitrogen, 



XXII. 0*271 grm. of the raw herring, Clupea Harengus, 

 gave 0*590 grm. of ammonio-chloride of platinum, equal to 

 14*48 per cent, of nitrogen. 



XXIII. 0*314 grm. of boiled herring gave 0*636 grm, of 

 ammonio-chloride of platinum, equal to 12*85 per cent, of ni- 

 trogen. 



XXIV. 0*350 grm. of purified muscle of the herring gave 

 0*802 grm. of ammonio-chloride of platinum, equal to 14*54 

 per cent, of nitrogen. 



XXV. 0*4065 grm. of the milt of the herring gave 0-940 

 grm. of ammonio-chloride of platinum, equal to 14*69 per 

 cent, of nitrogen. This substance is therefore as nutritive as 

 the muscular parts of the fish, containing the same amount of 

 nitrogen. m-xt 



XXVI. 0*316 grm. of the flesh of the haddock, Mglefinm 

 communis^ gave 0-729 grm. of ammonio-chloride of platinum, 

 equal to 14*64 per cent, of nitrogen. 



XXVII. 0*331 grm. of boiled haddock gave 0*677 grm. of 

 ammonio-chloride of platinum, equal to 12*98 percent, of nitro- 

 gen. Whereas in the case of the herring, salmon, haddock, and 

 eel, the proportion of nitrogen was considerably diminished
