us in its solubility in alcohol ; the alkaline solution is turbid. 

 It is not soluble in ether, or very slightly so; when burnt it 

 leaves an ash consisting principally ot" carbonate of lime. 



The cold alcoholic solution, on evaporation, left a sub- 

 stance similar in many respects, but much softer, even fluid. 

 It burnt in the same manner, leaving a slight ash of carbonate 

 of lime. The merest trace of copper was found in these sub- 

 stances. 



The action of the alcohol being continued, nothing at last 

 remained but dirt and mechanical impurities. The softer 

 portions from the surface of the v/ater were found to contain 

 a quantity of unchanged fat and oil. 



The milky water, on examination, was found to be a mix- 

 ture, probably, of this substance and water. It undergoes no 

 change in appearance when left for many weeks ; but when 

 filtered through good filtering paper, the latter portions came 

 through clear and transparent, the altered fat being separated. 

 When evaporated, it leaves a substance having all the pro- 

 perties of the solid matter above described. The finely-divided 

 state of the substance, its solidity, and its near approach to 

 the specific gravity of water, will, perhaps, account for the 

 length of time during which it will remain uniformly diffused 

 through it. — Journal of Science^ xvi. 172.
