Here too it appears, that in the different experiments the per- 

 centage rehitiou between protoplasm and intracellular fluid shows 

 but little deviation, and corresponds in a most striking manner with 

 what was found in the white corpuscles of the same animal. 



We were now interested in ascertaining what results the blood- 

 corpuscles of a rabbit would yield. 



We took some blood from the ear and defibrinated it. After care- 

 fully filtering off the fibrine, it was mixed with salt solutions in 

 the same way as the corpuscles of the horse. In the following table 

 are found some of the results obtained The number of white cor- 

 puscles after defibrinating is, however, so small, that we are almost 

 justified in considering the result as proceeding exclusively from the 

 red corpuscles. 



RABBIT-BLOOD. 



These experiments indicate a smaller volume for the protoplas- 

 matic network than was found in the horse. 



In the third place we communicate a few determinations with 

 the blood-corpuscles of the frog.
