only water, protein (“ albuminous matters”), fat, ami ash. The figures 
in the other columns of Table 24 are computed to the forms used in 
this report, as was done with the analyses of Payen, Kbuig, and others 
above. As already explained, these data were received after the pres- 
ent report had been prepared for the printer and hence can not be 
treated as fully as would otherwise be done.

ANALYSES BY SEMPOLOWSKI. 
In a paper entitled u Untersuchungen von Seetieren auf ihren Gehalt 
an agrikultur-chemiscli wichtigen Stoffen,” * L. Sempolowski gives the 
results of analyses of fishes with a view to learning their fertilizing 
value. The specimens analyzed included the whole fish, except in the 
cases of No. 1, from which fat had been extracted, and No 5, in which 
separate analyses were made of the flesh and of the head and bones. 
The following tables are translated from the original. As no further 
reference is to be made to the results in the present report the numbers 
are not made consecutive with the previous ones.
