add the alcohol ; digest for twelve hours ; then filter, and 
add the camphor and oil of rosemary. 
The castor oil and ammonia make a soap soluble in alco- 
hol. It forms a transparent liniment, yellowish in color, 
and will not coagulate in cold weather. And it always

In the Journal for October, 1848, will be found a notice 
of the first volume of this work, which has subsequently 
been completed by the issue of the second. In that notice 
the general scope and value of the work were pointed 
out, with a brief review of the several topics to which the 
volume was devoted. The present continues them, embrac- 
ing the subjects of Glass making, Alum manufacture, 
Copperas manufacture, Clay wares, China ware manufac- 
ture, Stone ware manufacture, Bricks, Lime, Gypsum and 
Magnesia. Most of these subjects are of importance and 
interest to the pharmaceutist, and we conceive we shall be 
performing a useful task in presenting such information, 
derived from this work, as will aid and abet him in his 
profession.

should not be substituted for the officinal, when the latter is pre- 
scribed. — Ed.
