These give in 100 parts—

Burnt with the bioxide of copper: 
Exp. 1. 0.708 gram. silver salt gave 0.582 gram. carbonie acid, 
and 0.174 gram. water. 
Exp. 2. 0.787 gram. of silver salt gave 0.6465 gram. carbonic 
acid, and 0.190 gram. water. 
These experiments give the following per centage.

This formula agrees with that of adipinate of silver, as made 
out by Bromeis, with the unimportant difference of one atom of 
hydrogen, and its physical properties and reactions are the same 
as adipinic acid : I consider it as such. 
None of the other acids afforded by the oxidation of sperma 
ceti, have been obtained in state of sufficient purity to be — 
ined. There is however one among them, whose copper and 
zine salts are more soluble. in cold than in warm water, and if 2 
ution of either of them be heated a precipitate is formed, which 
ives upon pnooling 5 this phenomenon is most. striking in ° 
ose portions of the examination of AP? aed 
, 1 propose finishing at some.
