340 CIRCULATING FLUIDS: 



we cannot lielp feeling surprised at the large amount of solid 

 constituents that occur in this analysis ; it can only be explained 

 by supposing that a larger amount of fluid was removed from 

 the blood by secretion and excretion than aa as supplied to it by 

 the drink. Another peculiarity is the increase of fibrin and of fat, 

 and the diminution of blood-corpuscles; this change may, how- 

 ever, be readily explained, for as long as the organs of respiration, 

 secretion, and excretion, continue to discharge their functions, 

 the blood must ob\dously be changed by them, and this change 

 Avill especially affect the corpuscles. The horse passed little 

 urine during this time, but this little was tolerably saturated. 

 It was by no means strong at the commencement of the expe- 

 riment, but at its termination it was much exhausted, and the 

 respiration became gasping. The blood formed a very strong 

 inflammatory crust. 



The blood of a healthy ox,^ and of a healthy calf, yielded 

 the following results : 



In the former of these analyses, the fluid which was examined, 

 was a mixture of arterial and venous blood, from which the 

 fibrin had been previously removed: in the latter case the ex- 

 tractive matter was not separated from hsematin. The number 

 105-925 represents the globulin perfectly free from colouring 

 matter. 



[Andral, Gavarret, and Delafond, have published a valuable 

 essay on the blood of some of our domestic animals in health 

 and disease. They made no less than 222 anatyses of the blood 

 of 155 animals, viz. 41 analj^ses of the blood of dogs, 31 of 

 horses, 110 of sheep, 2 of goats, 23 of oxen and cows, and 7 

 of swine. 



' Berzelius (Thierchemie, p. 98) found, in the serum of the blood of oxen — water 

 905, albumen 80, alliuminate of soda and lactate of potash 6-2, chloride of potassium 

 2-6, and modified albumen with carbonate and phosphate of potash 1-5.
