XXXV.— On the Products of the Destructive Distillation of Animal Matters. Part IV. 
By Tuomas Anperson, Professor of Chemistry, University of Glasgow. 
(Read 20th April 1857.) 
Owing to the great length of time over which the investigation of the pro- 
ducts of the destructive distillation of animal substances has stretched, and 
various circumstances which it is unnecessary to detail, the inquiry has been 
pursued in a somewhat fragmentary manner, and with less continuity than 
might have been desired. The difficulties attending many of the experiments, 
and the occasional exhaustion of materials prepared by laborious processes, ex- 
tending in many instances over considerable periods, have occasioned long inter- 
vals in the regular course of the inquiry which it became necessary to occupy 
with the examination of such matters as could be taken up at the moment. In 
this way a number of facts required to complete the history of the bases already 
described have gradually been accumulated, some of the products of their decom- 
position examined, and the pyrrol so frequently adverted to in the previous 
parts of this paper has been subjected to a full investigation. The details of 
these experiments form the subject of the present communication. 
It has been already shown that the whole series of the alcohol bases, from 
methylamine to butylamine, can be obtained from bone oil, and the probable 
existence of amylamine in the portion boiling, about 200°, has been pointed out. 
The quantity of base obtained at that temperature is by no means large; but 
enough was collected not only to prove the existence of amylamine, but to sub- 
stantiate the fact that it was unquestionably that base, and not one of its 
isomeres. After sufficient rectification it gave, with bichloride of platinum, an 
extremely beautiful platinum salt, which, when the fluid was sufficiently concen- 
trated, deposited itself after some time in fine golden yellow scales, very soluble in 
water. The mother liquor, on evaporation, yielded another crop, agreeing with 
the first in properties and composition. A platinum determination of each gave 
the subjoined results :— 
I. 5°39 grains of the platinum salt gave 1°815 grains of platinum. 
II. 2°99 grains gave 1-010 grs. platinum.
