Should the above experiments, to which I shall add no remarks at pre- 
sent, appear of sufficient interest, you will, perhaps, oblige by giving 
them a place in your journal. 
Opiate oil. — f Oleum opiatum. J — This preparation is made by di- 
gesting at a certain degree of heat, an ounce of crude opium in 16 oz. of 
oil of henbane, and finally expressing. The difficulty attendant upon 
mixing the tinctures of opium in use, with fatty substances for external 
application, has induced M. Neuber to introduce this preparation into 
practice. It answers well the end for which it is designed, and M. Neuber 
has already employed it with much success, either alone, or combined 
with ointments, or with aqua ammoniae, as volatile liniment.

Protoxide of Mercury. — Mialhe states that Donovan has inaccurately 
stated, that the sub-oxide of mercury may be isolated by means of corro- 
sive sublimate, and an excess of a cold solution of caustic potash. By 
this process, as by others, metallic mercury is procured, and a corres- 
ponding quantity of deutoxide, as Guibourt has proved in his inaugural 
dissertation. Bull. Gen. de Therapeutique.
