Other methods also I have found promising, but I have been 
compelled to give up the inquiry, at least for a long time, on 
account of the extremely nauseous emanations which pene- 
trated every room in the laboratory, and were, no doubt, 
waiting for a favourable opportunity of changing into deadly 
poisons. These, by proper arrangements, might be avoided. 
I mentioned formerly that the temperature of 54° Fahr., or 
12° C, was a very marked one in favoring putrefaction. 1 
now find that on to 120° Fahr., (49° C,) at least, the process, 
if it ceases, may be set in motion by raising the temperature. 
After that point it is difficult to induce putrefaction. I give 
here a specimen of the

After the decomposition had proceeded to such an extent 
that it was difficult to obtain even a few bubbles more, the 
gases existed in the following proportion : — 
Carbonic acid 97.09 
Sulphuretted hydrogen . . . .. 1’93 
Hydrogen 0-18042 
Carbonic oxide 0-13968 
Marsh gas 0*07295

A trace of a compound of cyanogen was found, and a 
small amount of phosphorus was obtained in the acid
