ALBUMEN. 343 



albumen from other insoluble protein-compouds in the animal 

 body. 



As we purpose in the second volume entering fully into the 

 quantitative relations of the albumen in the blood, it will be suffi- 

 cient here to observe, that the recent investigations of Becquerel 

 and Rodier,* with the older ones of Lecanu,f Denis^J Simon, 

 Nasse, and others, are tolerably agreed in stating that the quantity 

 of albumen in normal blood fluctates between 6'3 and 7'1 and in 

 normal blood-serum between 7*9 and 9'8% ; Scherer's is undoubt- 

 edly the best method that has yet been proposed for the analysis of 

 the blood, which, according to his results, contains in healthy men 

 from 6-3 to 7'0f of albumen. Nasse|| and Poggiale^f found on 

 an average less albumen in the blood of most animals than in that 

 of man, the highest quantity being 6*7$. The blood of men 

 appears from the concurrent observations of experimentalists to 

 contain rather less albumen than that of women. 



The chyle contains less albumen than the blood, but the quan- 

 tity is variable, as may readily be conjectured from the nature of 

 this fluid ; according to Nasse** it averages from 3 to 6$. 



Marchand and Colbergft found only 0'434 of albumen in 



human lymph, while in that of horses NasseJJ found only 0*391$, 



including some fibrin, and Schlossberger and Geiger only 0'62. 



The white of hens' eggs contains, according to Berzelius,|||| from 



12 to 13'8f of albumen. 



The serous fluids of the animal body, physiological as well as 

 pathological, contain much less albumen than the serum of the 

 blood, as indeed might be inferred a priori from their density ; they 

 are however never wholly free from it. 



The animal tissues are almost all surrounded by albuminous 

 fluid ; but the large quantity of albumen found in many of these 

 tissues depends upon the numerous capillaries by which they are 

 intersected ; as we specially observe in such organs as the liver, 

 kidneys, brain, and muscles.
