October 24, and fig. 17, following b, at the end of each. The new diffusion 

 constants were somewhat smaller than the above, but they are still much 

 higher than the normal values, /. e., the new data are equivalent to 



I'o = 0.0383 c.c. /day; whence 10^^ = 2.56 



To interpret this result, it will first be necessary to remove the copper 

 partition, which has been supposed to be an absorbent for oxygen, and to 

 replace it by a partition of mica. This will be done in the next paragraph. 

 Including the last results the mean constants for the 50 days of obser- 

 vation would be 



10 = 0.0505 c.c./day 10^ = 3.38 



retaining the abnormally high value. 



40. The Same, Continued. — The apparatus was now taken apart, 

 the copper partition removed and replaced by one of mica of the same 

 height. It was then charged with fresh water, etc., and placed in the vault 

 in question. The record of observations is given in table 17 and fig. 18.
