BLOOD. 20.) 



it contained therefore (in tins instance) a greater proportion of 

 solid constituents than arterial ; a less proportion than venous 

 blood. This proportion, 16-90[;, is however less than is usually 

 met -with in arterial or venous blood. 



The blood of the vena portte of a horse fed with oats gave 

 20*35 of solid constituents, while the arterial and venous blood 

 of the same animal gave 22*91? and 19*5? respectively. Here 

 the solid constituents of the blood of the vena portse bear an 

 exactly opposite proportion to those of arterial and venous blood, 

 for in this case they exceed those of arterial, and are less than 

 those of venous blood. 



The amount of the per-centage of the sohd residue, although 

 still deficient, approximates very nearly to the ordinary average.

remarks. 



Fibrin. 



As an average of thi'ee analyses, '32^ of fibrin was obtained 

 from the blood of the vena portse, while the proportions obtained 

 from arterial and venous blood were 1*04^ and 1*09? respectively. 

 Hence it may be concluded that this blood is poorer in fibrin 

 than either arterial or venous blood — a point which is con- 

 firmed by my own observations. 



Albumen with salts, and blood-corpuscles.^ 

 The following results were obtained from his analyses : 



The analyses 1 were made with the blood of fasting horses ; 

 the analyses 2 with the blood of horses after a recent meal 

 of oats. Hence it follows that the blood of the vena portse 

 contains more blood-corpuscles and less albumen than arterial 

 or venous blood. My own analyses do not exactly coincide 

 with these remarks. 



Fat. 



The solid residue of the blood of the vena portse gave (as the 

 mean of four analyses) 1*66|] of fat, while the corresponding 



' Schultz's method of analysis is described mi note 1, p. 198.
