of any other blood ;) in this manner I obtained, after the most 

 careful washing and boiling with alcohol, 0*245^ of these cell- 

 membranes from the clot of the portal blood, while from the 

 hepatic venous blood, similarly treated, I obtained from 1*98 to 

 2'43-g-. This cell-membrane was perfectly insoluble in a solution 

 of nitrate of potash (even after 48 hours 5 digestion at 35) ; I was 

 unable to discover sulphur in it by boiling it in potash-ley, &c. 



If this behaviour of the membranes of the coloured cells of 

 the hepatic venous blood indicates that there is here an excess of 

 newly- formed or rejuvenescent blood- corpuscles, the proof that a 

 formation of new blood-cells takes place in the liver is fully 

 confirmed by a comparison of the contents of the corpuscles of 

 the two kinds of blood. We find far less hsematin in the cells of 

 hepatic venous blood, than in those of portal blood ; for on an 

 average, 180 grammes of the moist cells of hepatic venous blood 

 contain scarcely so much iron as 100 grammes of the cells of 

 portal blood. On the other hand, there is more globulin or 

 coagulable matter generally, and more chloride of potassium, but 

 considerably less fat, in the cells of the hepatic venous blood, than 

 in those of the portal blood. 



In the blood of the hepatic veins, the fibrin is either entirely 

 absent, or is present in mere traces ; while in the portal blood, 

 taken at the same time, we often find a perfectly normal, strongly 

 contracting fibrin. 



The serum is relatively much less abundant in the blood of the 

 hepatic veins than in that of the portal vein ; while in the latter 

 there are 70 parts of serum to 100 of corpuscles, in the former there 

 are only 32 parts of serum to a corresponding quantity of cells; 

 if the portal blood happen to be rich in water, as, for instance, 

 when there are 287 parts of serum to 100 of cells, the blood of 

 the hepatic veins will, even then, not contain more than 73 parts 

 of serum to 100 of cells. 



The serum of the hepatic veins is certainly more concentrated 

 than that of the portal vein ; if we accurately compare the two, 

 we find in the former, a relative and absolute diminution of the 

 albumen (there being in 1000 parts of the serum of the hepatic 

 venous blood fully a third less albumen than in an equal quantity 

 of the serum of portal blood), while on the other hand, as has 

 been already mentioned, the globulin in the blood-cells is relatively 

 and absolutely increased. The phosphates, chlorides and potash- 

 salts are diminished in the serum, but are in excess in the cells of 

 the hepatic venous blood. Sugar is relatively and absolutely more
