Experiments on Beef. — Lectures. 15^ 



parent alterations, and the air in the bell-glass preserved its 

 volume. At the end of seventv-six days, din-iiig which time the 

 temperature had varied from to 10° Reaumur, the meat had 

 scarcelv acquired any smell of sulphurous acid : it was harder 

 and drier than roasted meat. After lea,ving it four days in the 

 open air, it then became mere compact without being putrefied, 

 and did not perfectly change colour : it merely lost the weak 

 smell of acid without acquiring anv other. 



A piece of ox beef was treated in the same way in the fluoric 

 acid gas, and the results were in every respect similar : the phse- 

 nomena were only less visible, because the acid attacked the 

 glass, and a thin coating of mercury was deposited on the meat. 



Beef deposited in a receiver filled with ammoniacal gas exhi- 

 bited alterations completely different : the absorption of the elastic 

 fluid had taken place in it totally; the meat assumed a fine red 

 colour nearly as in the nitrous gas, and preserved this fresh ap- 

 pearance for seventy-six days: it was much softer than in the 

 foregoing experiment, without smell, and having the colour and 

 consistence of fresh meat. When exposed four days to the open 

 air it did not putrefy; it lost its red colour, however, became 

 brown, dried up, and was covered with a kind of varnish.
