24 June, Temp. 65°, P. 29*95. 

 Exp. 14. A mouse being placed in the usual manner in Mouse in oxi- 

 a jar, containing 3 cubic inches of oxigen of the purity of » en - 

 98, in 30 minutes it was quite dead. The air had then de- 

 creased by observation 1*00 cubic inch. The residuum 

 being treated with lime water, 33-67 per cent disappeared. 

 This was the average of two trials, and 100 parts taken of 

 the remainder, and submitted to impregnated sulphate of 

 iron, 84 per cent were absorbed, making the whole by calcu- 

 lation stand thus.

At the same time another was passed up into 3'50 parts of 

 oxigen gas, and at the expiration of 40 minutes 0*90 parts 

 were diminished.

Exp. 15. In the same manner a mouse was passed up Mouse jnosi 

 into 1*70 cubic inch of oxigen gas. After it was in, the g en S as - 

 scale indicated 2*80 cubic inches. When withdrawn in ten 

 minutes, 1*50 cubic inch. 100 parts being then examined 

 with lime water, 21 parts were taken up, and the remaining 

 79 parts being exposed to the test for oxigen, 67 parts dis- 

 appeared, leaving a residue of 12 parts, which appeared to 

 be nitrogen. 



11 July, Temp. 60°, P. 29"80. 



Exp. 16. Another being passed up into 1*60 cubic inches Another. 

 of oxigen gas, the scale then indicated 2*40 cubic inches. 

 When the mouse was quite dead, it had diminished to 2'05 ; 

 and after it was taken out to 1*25 ; showing an absorption
