246 CIRCULATING FLUIDS: 



Water . . . may vary from 888-0 to 750-0 



The analyses of the French chemists gave the following 

 results, with regard to this subject. 



Taking the mean of Lecanu^s analyses of healthy blood as a 

 standard, and contrasting with it the extreme results which 

 were found by Andral and Gavarret in diseased blood, we have 

 the following results: 



From these data, it appears, that although the proportions of 

 all the constituents are subject in disease to a certain amount 

 of change, the variation is the most striking with regard to 

 the fibrin and globulin. 



The former is found in my analyses occasionally to exceed 

 four times the average quantit}^, and in Andral and Gavarret's, 

 three and a half times ; while the latter may diminish, accord- 

 ing to my analyses, to a mere trace; and according to Andral 

 and Gavarret's, to one sixth of the normal quantity. 



These determinations must not, however, be regarded as ab- 

 solute : they are dependent on various causes, and can be ex- 

 plained in more ways than one.
