79.9% of oxygen. The tension of this gas is therefore 879, correspond- 

 ing to about 44 atmospheres of air. 



B. Another cutlet is hung up in a huge closed bell. 

 November 19. B is foul. 



A looks good. The manometer has fallen to 7 atmospheres. The 

 air, which has absolutely no odor, contains 78.4% of oxygen and not 

 a trace of carbonic acid. 



I raise the pressure again to 11 atmospheres with new oxygen. 



November 21. Still no bad odor in A; appearance good. 



I take a fresh cutlet C, and hang it in a bell absolutely full of 

 water. I then admit to this bell a certain quantity of compressed air 

 coming from A; some water remains at the bottom of the bell. A 

 then drops to 6.5 atmospheres. 



November 24. No odor in A. A very slight leak is permitted so 

 that on November 25 the pressure is normal; the cutlets have a yel- 

 lowish color. 



B is then in complete putrefaction. C is yellowish, and the water 

 has risen in its bell. 



December 13. I open the apparatus and end the experiment. 



A. Meat, rose colored, a little acid; faint odor of pickle. I have 

 the cutlets broiled; they have an insipid, but not repulsive taste. 



B had to be disposed of December 10, reduced to absolute decay. 



C. Meat flabby, pink, a little acid; disagreeable odor, not that of 

 ordinary putrefaction. 



Experiment CCCLXXXIX. November 22. 



A. In the Seltzer water receiver (1050 cc.) are placed two cutlets, 

 which are taken to 8 superoxygenated atmospheres. 



B. Another cutlet is placed in oxygen under a bell. 



C. A third, under a bell, in air. 



November 24. A has dropped to 2 atmospheres; I take it back to 

 8 atmospheres; the meat is a dull red. 



B is bright red. 



C is of ordinary color. 



December 1. A has no bad odor; normal consistency; alkaline 

 reaction; yellowish appearance. 



B. Bad odor; alkaline reaction. 



C. Absolutely foul odor; flesh diffluent; acid reaction; darkens 

 paper with lead acetate. 



Experiment CCCXC. December 11. 



Under two bells inverted over water, one of which, A, contains 

 air, the other, B, oxygen, fragments of muscle are hung. 



January 8. The air is foul in both bells; A shows a great deal of 

 mold; B, only a little. 



Experiment CCCXCI. December 19. Three pieces of lean meat are 

 cut as nearly alike in iorm as possible. 



A. One, weighing 45 gm., is hung under a closed bell, of 11.5 

 liters, full of ordinary air. 



B. The second, weighing 40 gm., is hung in a bell of 3.2 liters, 

 which contains air with 90% oxygen.
