The blood had a specific gravity of 1*0317 and yielded 3'327-- of ash. 



(30 Addition to p. 260, 12 lines from the bottom. Funke's 

 very carefully conducted examination of the blood of the splenic 

 vein in horses does not, unfortunately, either confirm or refute 

 Beclard's conclusions, while my own experiments on the arterial 

 blood of the same animals (from which the blood of the splenic 

 vein had been taken) exhibited such different results, that no 

 general deductions could be obtained in reference to any one point. 

 The juice expressed from the spleen which J. Scherer* analysed 

 consisted principally of blood, yielded by the capillaries of the 

 spleen. Scherer found that it contained in addition to albuminous 

 matters and salts, lienine, hypoxanthine, two different kinds of fer- 

 ruginous pigments, a large amount of free iron not combined with 

 pigments, and acetic, formic, and lactic acids. 



This investigation of Funke affords, at all events, a proof that 

 the greatest caution is necessary in deducing conclusions from 

 individual analyses and investigations of individual fluids, without 

 reference to the simultaneous constitution of the other animal 

 juices. Many ingenious conclusions would no doubt have been 

 deduced from analyses of the blood of the splenic vein, if the 

 arterial blood had not been simultaneously compared with it. 



(31) Addition to p. 261, line 8. The blood of the placental 

 vessels contains, according to Stas,t little albumen and fibrin, 

 whose place is, however, supplied by a large amount of a substance 

 which he calls casein (see p. 483 of this volume). Stas also 

 believes that he has found urea in this blood.

 C. SchmidtJ has endeavoured by careful and numerous experi- 

 ments to establish the proposition, that the loss of albumen in 

 the blood is supplied by a relatively corresponding amount of salts, 

 as for instance, chloride of sodium. Thus we find that wherever 

 albumen is lost from the blood, either by accidental or intentional 

 blood-letting, by morbid exudation from the capillaries of the
