Relation of Chloroform to Blood.

The first part of the absorption is lost in each case during intro- 

 duction of fluid into the bottles. The first pair of readings are 

 taken at the end of the second minute. The second readings at the 

 end of the fourth minute, when both bottles are equally shaken for half 

 a minute, after which the third readings are taken. The fourth and 

 fifth readings are similarly taken at the seventh minute, the bottles 

 being shaken a second time, S 2 . 



The bottles are left at rest for 7 minutes before the last readings, 

 which show that the absorption has been nearly but not quite 

 completed.

The vapour in the two bottles was then passed into and through 

 two densimeter bulbs by water displacement. The increments of 

 weight in the two cases were : in A 0*054 gramme, in B 0'032 gramme, 

 showing that the residual atmosphere in A (water) contained more 

 chloroform vapour than that in B (blood).
