This formula makes a preparation, which Mr. Car- 
penter, who has furnished it to me, informs me, 
will keep well. The hia is to be dissolved, 
in the acidulated alcohol, the water gradually

Robiquet had observed, that the process for obtaining mor- 
phia, did not entirely deprive the opium of the alkaline 
salt. ,The residuum, still containing some, exerted a nar- _ 
cotic property, on animals, subjected to its exhibition, by 
ndie, as well as on man; he observed that this was 
less energetic than the effect of common aqueous extracts, 
but sufficiently decided to lead him to the opinion that it 
ought to be kept by apothecaries, who prepare their own 
morphine. Dose, may be regulated by his statement, that 
4 grains are scarcely equivalent to one grain of the ordi- 
nary watery extract, or to 4 of a grain of morphine.

Obtained by Sertuerner, -by a detailed process this generali- - 
zed: repeatedly exhausting opium in two parts of boiling 
ether, mixing the solutions, filtration, evaporization of the 
ether; this yields a twofold product, viz.; 1. a saline crust, 
being a union of'na with an acid; 2.a brownbitter _

resin, allows the narcotine to be precipitated from the f 
ed liquor, by ammonia. Narcotina is obtained afterwards 
from the saline crust, by depriving it of the resin and 
caoutchouc, by means of rectified bil of turpentine, wash- 
ing the residuum in cold alcohol, then dissolving it in hot, 
and precipitating the narcotine, by ammonia, as before. 
The two precipitates are again dissolved in a minute por- 
tion of h oric acid, and re-precipitated by the same 
agent as Mr. Carpenter has obtained | 
this city, by a similar process; and he informs me, ina 
letter, that he has “ discovered that the feculencies of opium, 
from which laudanum had been made, contain a consid- 
erable portion of narcotine, resin, caoutchouc, &c. 1 :
