The proportion of oxygen in the bases to that of the phos- 

 phoric acid was as 2 ; 5, i. e. the salts were pyrophosphates ; 

 and in this respect this ash has some analogy with that of 

 wheat, which, however, contains far more alkaline chlorides. 



Thus water and muriatic acid principally exti'act alka- 

 line phosphates from carbonized flesh, and alkaline chlorides 

 and carbonates from carbonized blood. The muriatic extract 

 of the blood contains altogether so few constituents, that we 

 may suppose they are only those which had previonsly resisted 

 the solvent action of water, or were formed from the anoxidic 

 portion of the blood by the imperfect exclusion of the air 

 during its carbonization. 



If so, and we admit that the alkaline chlorides and car- 

 bonates do not belong to those constituents of the blood, the 

 inorganic portions of which consist of phosphates in an oxidized 

 and unoxidized state, these constituents of the blood would 

 contain the phosphates in a perfectly deoxidized state. Such 

 are probably the proteine substances of the blood, which would 

 then differ from those of the flesh, by the former being anoxi- 

 dic and the latter meroxidic substances. Probably in future 

 we must only call those substances anoxidic, meroxidic, and 

 teleoxidic, the inorganic constituents of which consist princi- 

 pally of phosphates in a deoxidized, partly oxidized, and per- 

 fectly oxidized state. The blood will then be an anoxidic, 

 and the flesh a meroxidic substance.

Analysis of the Ashes of Human Faces and Urine, By 

 M. Fleitmann. 



Although a single analysis of the ash of the faeces, without 

 regard to the diet, can be of but little physiological importance, 

 inasmuch as it must depend greatly upon the nature of the 

 food consumed and upon the mode of life of the individual, yet 

 a comparative examination of the inorganic constituents of the 

 faeces and urine may afford us instructive conclusions regard- 

 ing the quantities excreted in the same period of time. Such 

 a comparison had not previously, I believe, been made, and as 

 we shall see, has yielded a remarkable result. For this purpose 

 the faeces and urine of a young man, aged 20, were carefully 

 collected during four days. During this period his diet was 

 very moderate, consisting principally of meat, and as little ve- 

 getable matter as possible. He drank no spirituous liquids, 

 and little liquid of any kind during the period, but he took 

 much corporeal exercise. 



JFlrces.-- 'When dried at 212° F. they weighed only lO^'lO 

 grms. They were carbonized as usual.
