ON ALBUMEN AND OTHER ANIMAL FLUIDS. gl 



The electro-chemical decomposition of this fluid affords, Soda, and mu« 

 beside the results just mentioned, a considerable quantity ifaieaJSf? 

 of soda at the negative pole ; and at the positive pole, a 

 mixture of muriatic and phosphoric acids. 



5. Milk. 



In this fluid, the separation of albuminous matter at the Milk, 

 negative pole is equally evident, though not so rapid, as in 

 most other cases. The conductors from sixty four-inch dou- 

 ble plates, highly charged, and immersed within four inches 

 of each other in three ounces of cows milk, during one hour, 

 produced the appearance of curds and whey, the principal 

 part of the curd being collected in the neighbourhood of the 

 negative wire, and but little at the positive wire. When 

 this experiment was so conducted, as to collect the products 

 in separate vessels, the predominating ingredients in the 

 contents of the negative cup were soda and traces of lime; 

 and in the positively electrified vessel, a mixture of muriatic 

 and phosphoric acids. 



After sirch decomposition of milk, the serum still affords 

 sugar of milk. 



6. The Liquor of the Amnios. 



An opportunity having offered of examining this secretion, Liquor amnii. 

 from the human subject, in its pure and fresh state, I shall 

 mention the general results of its analysis. 



The liquor of the amnios is almost perfectly transparent, Its properties} 

 but on exposure to air becomes gradually turbid, and depo- 

 sits a white flaky matter. It renders tincture of violets 

 green, and while perfectly fresh does not affect litmus ; but 

 sulphuretted hidrogen is soon evolved from it, and then it 

 slightly reddens litmus. When heated, it becomes turbid, 

 and lets fall flakes of coagulated albumen. Acids render it 

 ■li ;tly turbid from the same cause. 



Alkalis produce no change, unless when added in consi- 

 derable excess : the odour of ammonia is then perceptible. 



Electrical analysis afforded albumen and sodaatihe nega- \ dilute solu- 



ttve pole, and muriatic acid at the positive pole. Hence we tion of liquid
