170 Miscellaneous Intelligence. 
The conclusions appended to this mémoire, are, 1, thatit i s 
possible in many cases of poisoning by acetate of morphia, to dis- 
cover sensible traces of this vegetable poison; 2, that the sub- 
stances vomited shortly after taking the poison into the stomach 
contain ponderable quantities of it; 3, that it is always in 
those viscera into which it has been introduced, that its remains 
may be detected; 4, that all attempts as yet made to discover 
it in the blood of the dead animals have been fruitless.—Ann. de 
Chim. xxv. 102. 
24. Test for Morphium—M. Dublane a druggist of Paris, states 
that he finds the tincture of nutgalls a very. sensible test of the 
presence of morphium in fluids, whether it exist free or in combi- 
nation with acetic or sulphuric acid.— Ann. de Chim. xxv. 92. 
25. Process for obtaining Strychnia, by M. Ferrarti.—Boil three 
pounds of bruised nux vomica for two hours in thirty pints of 
water acidified by six ounces of muriatic acid, and pass the 
liquid through a cloth or sieve: the residue should be thrice 
boiled again for the same time, and in equal quantities of acid and 
water. To the united cold infusions add lime slowly whilst mix- 
ing, until in considerable excess; after two or three days decant 
the liquid, collect the paste on a filter, dry and powder it. The 
decanted liquor should be rather more than neutralized by muri- 
atic acid, evaporated until reduced to a few pounds, when cold 
precipitated by lime, allowed to stand, decanted, and the residue 
when dry, powdered and added to the former. 
Sulphuric acid may be substituted for muriatic acid in the pro- 
cess, but the three pounds of nux vomica will require only three 
ounces of this acid in twenty pints of water, and the boiling 
should continue one hour only. Afterwards, the liquid rendered 
acid is to be concentrated until like syrup, being agitated during 
the evaporation if any deposit appears. ‘To the cold liquor pow- 
dered lime is to be added, and the process goes on as before. 
The mixed precipitate of lime and strychnia obtained by either of 
the above methods is to be heated in a water-bath two or three times, 
with alcohol of specific grav. 0.832, until all the bitter principle is 
extracted. The united fluids are to be distilled, and this operation 
finished ; there will remain a yellow turbid bitter alkaline fluid, 
which is to be decanted off and reserved, and beneath it the 
strychnia soiled by a yellow colouring matter, which will harden 
upon cooling. This mixture treated with cold alcohol of specific 
gravity .915 will leave pure strychnia.—Gvor. de Fisica. 
26. Volatility of Salts of Strychnia.—Il Sig. Ferrari bas remarked 
that solutions of salts of strychnia slightly acid when exposed 
to a heat of 212°, so as to be concentrated, then become volatile 
and the salt evaporates. This property has been remarked in the sul-
