MISCELLANY. 
second time, and precipitated with milk of lime, to decompose the solu- 
ble magnesian salts. The precipitate is collected, the lime separated by 
sulphuric acid, avoiding an excess of acid, the liquid is evaporated to se- 
parate the sulphate of lime; the last traces of lime are removed by oxalic 
acid ; the free acids, and the extractive matter, by neutral acetate of lead ; 
and the surplus of this last removed by treating the filtered liquid with a 
current of sulphuretted hydrogen gas. Evaporation is next performed to 
remove the acetic acid, the extract is redissolved in a small quantity of 
alcohol, and the mannite is separated by crystallization. The extractiform 
residue is dissolved several times in cold strong alcohol to separate the 
remainder of the mucuso-sugary matter ; finally it is allowed to evapo- 
rate. 
The ligustrine is a yellow extractiform mass, bitter, hygroscopic, and 
retaining traces of acetic acid and mucoso-sugary substance. It is soluble 
in alcohol and water, but insoluble in ether and absolute alcohol. The 
metallic salts and the alkalies form no precipitate with it ; with sulphuric 
acid there is obtained a superb azure color. When the solution is concen- 
trated, the color is a deep indigo blue. By diluted sulphuric acid, these 
changes of color are not produced. 
The constituent parts of Ligustrum vulgare are — ligustrine, mannite, 
fermentable sugar, muco-sugary matter, amylum, chlorophylle, bitter ex- 
tractive, bitter resinous matter, tannin, albumen, salts principally with 
magnesia as a base, lignin. 
Employment of Hydrated Peroxide of Iron as an antidote for ScheeWs 
green. By Dr. Spaeth, of Esslingen — An infant, three years old, having 
swallowed a spoonful of Scheele's green, (arsenite of copper,) very soon 
became attacked with violent vomiting, diarrhoea, violent pain in the belly, 
and insatiable thirst. He was in the first instance made to drink cold 
water, and then fifteen grammes of the peroxide of iron where administered 
to him, suspended in hot water. He took four doses of it. An hour after 
the employment of the antidote, both the vomiting and the diarrhoea had 
ceased, as well as the pain and the thirst ; the next day all the symptoms 
of poisoning had ceased.

The Indian mode of preparing the Perfumed Oils of Jasmine and Bela. — 
Dr. Jackson, of Ghazeepore,in a letter to the editors of the Asiatic Journal 
of Calcutta, for June, 1839, says : — In my last communication on the sub- 
ject of rose water, I informed you that the natives here were in the habit 
of extracting the scent from some of the highly smelling flowers, such as 
the jasmine, &c; and that I would procure you a sample, and give you 
some account of the manner in which it is obtained. By the present 
steamer, I have despatched two small phials, containing some of the oil
