the other from our fabric in the same manner as we had inserted them. When first 
I became acquainted with diethylated aniline, having then already observed the de- 
portment of the salts of ethylaniline, which under the influence of heat are recon- 
verted into aniline, I indulged for a moment in the pardonable illusion, that the salt 
of diethylaniline would exhibit the metamorphosis —

a mode of reaction which would have afforded a passage from the ethyl- into the butyl- 
series. This step however is reserved for a more fortunate experimenter. 
Platinum-salt of Diethylaniline. 
This salt resembles the corresponding compound of ethylaniline. On addition of a 
concentrated solution of bichloride of platinum to the hydrochlorate, it is precipi- 
tated in form of a deep orange-coloured oil, which rapidly solidifies into a hard cry- 
stalline mass. If fhe solutions are mixed in a dilute state, the salt is separated after 
some time in cross-like yellow crystals. It is not nearly so soluble in water and alcohol 
as the ethylaniline-salt. Analysis led to the following numbers : —
