C. Eggs. 



Experiment CCCCXVIII. June 19. Eggs beaten and well shaken. 

 Placed in equal quantities in: 



A. Flask with stopper, ordinary air. 



B. Flask closed with a cork stopper with a hole, subjected, after 

 agitation, to 20 superoxygenated atmospheres, equivalent to 88 atmos- 

 pheres of air. 



June 24. A. Foul, with mold on the surface. 



B. Decompressed, no odor. The flask has been uncorked by the 

 expansion of gases; the stopper has to be cut and replaced. The flask 

 therefore remains open to the outer air for about 5 minutes. I seal it 

 carefully. 



June 28. A. Is completely mottled. 



B. Appears wholesome, the yolk clearly floats on top. 



July 6. A. Horrible odor; the stopper pops out when the flask is 

 opened; the egg is all mottled and greenish. 



B. There are still two layers; yolk greenish; no odor; there is mold 

 on the lower surface of the stopper. 



July 12. B, which was recorked without precaution, has no putrid 

 odor. 



Experiment CCCCXIX. July 21, 1874. Beaten egg. 



A. In a matrass closed with cork stopper. 



B. In a similar matrass, drawn out in a flame. Subjected to 15 

 superoxygenated atmospheres, shaken. 



July 30. A. Smells horribly bad and is mottled. 



B. Decompressed; has no odor, and its two layers are very clearly 

 separated. I close it with the flame. 



At the end of several months, B begins to coagulate in a mass. 



January 18, 1875. A. Horrible odor; is only a greenish pulp, very 

 alkaline. 



B. I open the matrass; the egg is entirely coagulated; yolk reddish; 

 no disagreeable odor; reaction clearly acid. 



Experiment CCCCXX. May 29. Beaten egg. 



A. In an open matrass, covered with a paper cone; normal pres- 

 sure. 



B. In a matrass drawn out in a flame. Taken to 23 superoxygen- 

 ated atmospheres. 



June 5. A. Exhales a horrible odor. 



The compression apparatus has leaked; I make a recompression 

 several times; it finally drops to 5 atmospheres. 

 June 26. Decompression. 



A. Is coagulated, foul, with a dark layer at the bottom of the glass. 



B. Is divided into two very definite layers, not coagulated, with- 

 out odor. 



Experiment CCCCXXI. March 17. Beaten eggs, in 2 tubes. 



A. Closed with a stopper, free air. 



B. Drawn out in a flame; at 15 atmospheres of air containing 80% 

 of oxygen.
