to sink into oblivion. He affirms that he is fully convinced of the re- 
markable effects which may be obtained from its employment in the 
treatment of adynamic fevers, and especially in cases of hysterics. 
He prescribes vanilla under the form of infusion, prepared in close ves- 
sels, with from 1 to 4 parts of substance to 100 or 150 parts of boiling 
water. This quantity, properly edulcorated, is administered by spoon- 
fuls in the course of the twenty-four hours.

From the example of M. Royer, it is sometimes useful to associate 
with this formula a small proportion of opium, or Rousseau's laudanum, 
10 or 12 drops, which is added to the mucilage, for all the foregoing 
doses. V Experienca,from Ibid. 
Preparation of Hydrochlorate of Morphia. — M. Michiels, of Antwerp, 
advises the following process for preparing the hydrochlorate of morphia. 
He obtained, by ten ounces, more of the salt from 50 kilogrammes of 
opium than he would have procured by Gregory's process. Ten kilo- 
grammes of opium are treated with a sufficient quantity of cold water 
by the displacement method. The opium having been exhausted, and 
the solution filtered clear, it is concentrated at a moderate heat, until 
about eight quarts only remain, when a slight excess of a concentrated 
solution of the chloruret of calcium is to be added. The mixture hav- 
iug been heated for an hour, at 175° F., and continually stirred, the 
meconate of morphia is totally decomposed, and a white precipitate of 
meconatejof lime takes place, which can be separated by filtration. The 
liquid is.then passed boiling over purified animal charcoal; then concen- 
trated, and a large excess of hydrochloric acid added, by which a con- 
fused crystallisation of hydrochlorate of morphia and codeine is very 
soon obtained. This salt is collected, and pressed. As it is impossible 
to obtain all the morphia from the syrupy mother-water by a second
