ON CHLOROFORM AS A SOLVENT. 
5. Neutral proximate principles. Styracin, piperin, naththa- 
lin, cholesterin, [and we may add cantharidin — Ed.] are very 
soluble ; picrotoxin, slightly so ; paraffin only when hot, separa- 
ting as the liquid cools ; whilst amygdaline, phloridzin, salicin, 
digitalin, cynisin, urea, hematin, gluten, sugar, &c, are in- 
soluble. 
6. Organic acids. Benzoic and hippuric acids are very soluble, 
tannic but slightly, and tartaric, citric, oxalic, and gallic acids 
not at all. 
7. Organic alkalies. Quinia, veratria, emetia, and narcotina, 
[to which we may add, from the observations of others, nicotina, 
conia, and atropia,* — Ed.] are easily soluble, strychnia with less 
readiness, and appears to undergo a change in its morphic 
condition ; brucia is also moderately soluble, but morphia and 
cinchonia are insoluble in this menstruum. 
8. Salts of organic acids. Tartar emetic, citrate and lactate 
of iron, the acetates of soda and potassa, the valerinate of zinc, 
and acetate of lead, are all insoluble. 
9. Salts of organic bases. Sulphate and muriate of strychnia 
are soluble, whilst sulphate and muriate of morphia, and sulphate 
of quinia, are insoluble. 
10. Haloid salts. The iodide, bromide, chloride and ferrocy- 
anuret of potassium, the chloride of sodium, and muriate of am- 
monia, the iodides of mercury and potassium, are all insoluble 
in chloroform, whilst corrosive sublimate dissolves with great 
readiness. 
11. Oxy salts. The iodates, chlorates, nitrates, phosphates, 
sulphates, chromates, borates, arseniates, and alkaline hyposul- 
phates, are completely insoluble, as also are nitrate of silver, sul- 
phate of copper, and probably all the metallic oxysalts. 
* In a note to his paper, M. Lepage calls in question the statement of 
M. Rabourdin. (see vol. xxiii, page 139, Ainer. Jour. Pharni.) that chloro- 
form will dissolve atropia, and remove it from solutions. "We have tried 
M. Rabourdin's process with conia, and find that it dissolves it readily. The 
editor of the N. Y. Journal of Pharmacy, suggests that chloroform will pre- 
serve anatomical and pathological specimens, without change of color or 
apparently of texture. This probably applies to the muscular and gelatin- 
ous tissues, but specimens embracing adipose structure, would probably be 
altered. — Ed. Amer. Jour. Pharm.
