When I began to examine the products of the putrefac- 

 tion of blood_, it was with the object, first, of ascertain- 

 ing the nature of the gases; and next, of ascertaining 

 whether any matter in them exists in a so-called organic 

 condition, and, if so, in what quantity. I have ascertained 

 the nature of the gases ; so far as I see, however, I have 

 added no new one ; but I believe that for the first time I 

 have given the proportionate amount of each. After the 

 decomposition had proceeded to such an extent that it was 

 difficult to obtain even a few bubbles more, the gases ex- 

 isted in the following proportion : — 



Carbonic acid 97*09 



Sulphuretted hydrogen 1-93 



Hydrogen 0-1804 



Carbonic oxide 0-1396 



Carburetted hydrogen, CHg 0*0729 



Mtrogen 51*5171

Absorbed by lead and potash. Not absorbed.
