Chemical Composition of Human Bloody 125 



Not acted upon by caustic potash. 



{h). The oily liquid had an acrid taste and the consist- 

 ence of oil of turpentine. 



Insoluble in hot or cold water. 



Alcohol and ether dissolve it immediately when heated. 



Nitric and muriatic acids have no action upon it, but sul- 

 phuric acid destroys it. 



Potash or soda dissolves it by aid of a slight heat, and an 

 acid precipitates white flocks from the solution. These 

 flocks when separated possess acid properties. Boudet 

 regards them as a mixture of oleic and margaric acids. 



2. The solid portion insoluble in ether, dissolves in alco- 

 hol partially, when the whole is heated to about 100° Fah. 



The alcoholic solution evaporated to dryness, left an 

 orange yellow matter which was very deliquescent and 

 possessed an agreeable flavour. 



It had a decided taste of beef tea. 



The colour was orange yellow. 



Soluble in water and alcohol. 



Insoluble in ether. 



Causes a precipitate in acetate, of zinc, with effervescence 

 and strong smell of vinegar. 



After standing for some time, causes a precipitate in 

 acetate of magnesia with effervescence, and a slight smell 

 of vinegar. 



It was partly volatilized by heat. 



It would, therefore, appear to be a mixture of lactic acid 

 and extract of meat or osmazome, which agrees with the 

 researches of Berzelius. 



The portion insoluble in alcohol, dissolves in water and 

 acetic acid causes a slight precipitate, but I could not 

 examine it further from the small quantity in my possession. 

 From Lecanu's experiments, with which those I made agree 

 as far as they go, it would appear to be a compound of 

 albumen and soda. 



IV. THE «ALTS OF THE BLOOD. 



To ascertain the proportions of the alkaline salts, the 

 serum was treated first with very strong alcohol and then 

 with water. The alcoholic solution was found in the usual 

 way, to contain the chlorides of sodium and potassium.
