chloride of soda and an addition of muriatic acid may also be em-

On the Use of Artificial Ultramarine for Colouring Sugar. — In France, 
artificial ultramarine is employed for giving to dragees, bonbons, &c. ; 
a pretty blue colour. But if the latter contain some acidulated juice, 
they assume a very disagreeable taste of sulphuretted hydrogen, 
although the colour remains equally brilliant. Chevallier succeeded 
in preventing this, without prejudice to the colour, by boiling the ultra- 
marine before employing it, with water acidulated by acetic acid, and 
then washing n with hot water. — Pharm. 3 our n. from Journ. de Chem,

Pharmacy in China. — The Chinese are in advance of the English 
in the regulations established for the practice of Pharmacy, as none 
but qualified men are allowed to engage in business as Pharmaceu- 
tists in China, which is not yet the case in England. 
The Emperor of China has decreed, by a law passed in May, 1846, 
1. That the proprietor of every Pharmaceutical establishment shall 
be required to have a diploma, signed by three members of the Aca- 
demy of Medicine, who shall testify to his competency, after having 
satisfied themselves by an examination. 
2. That every Pharmaceutist shall be required always to keep cam- 
phor, rhubarb, and liquorice, in his shop. 
3. That purgative salts, calomel, laudanum, arsenic, and other simi- 
lar substances, shall be only sold when ordered by the prescription 
of a medical man, or sanctioned by a magistrate. 
The Pharmaceutist is also required to keep a sufficient supply of 
Ginseng rooU and to superintend the growth of the plant furnishing this 
very costly, but favourite Chinese remedy.— Pharm. Jour. } from Re- 
pertoire de Pharmacie.
