 analysis of 1,000 parts of corpuscles, the specific gravity being 

 1088.5, the water being to the solids as 2.14 to 1, and the or- 

 ganic to the inorganic constituents as 40 to 1.

The cell-membranes, once erroneously believed to be fibrine, when 

 isolated, form, in the moist state, a whitish-gray adhesive mass, which 

 has not a fixed composition. (Lehmann.) In the hepatic veins the 

 cell-membranes are distinguished from those of all other vessels in 

 not being made entirely to disappear by the addition of water. 

 They are, probably, an albuminous substance ; but not fibrine, nor 

 the cleutoxide of protein, as has also been stated. 



The viscid contents of the blood-corpuscles have been said to con- 

 sist principally of the coloring matter called haematine, held in solu- 

 tion by the globuline. Lehmann, however, terms it, as a whole, 

 hoemato-crystattine. We prefer the term hcemato- globuline (p. 96). 

 There is from 18 to 26 per cent, of dry hsemato-globuline in the 

 moist corpuscles ; in the whole blood, from 9 to 12 per cent. But 

 the haematine and globuline do not stand in a definite numerical 

 relation to each other. The insoluble ferruginous substance called 

 haematine does not exist as such in the blood, but is a product of 

 the transformation of the actual blood-pigment (p. 103). In the 

 blood the latter is soluble, and it is calculated to constitute 16 to 17
