xture of hard acid fat and bees'-wax, with
compounds of chlorine and oxygen, preferring to employ that disengaged
from chlorate of potash by treating it with sulphuric acid. For this
purpose, Mr. Wilson takes at the rate, say, of a ton of yellow
bees'-wax, and melts and boils it up with free steam for about half an
hour. It is then allowed to stand a short time, and is then decanted
into another vessel provided with a steam-pipe to emit free steam; about
20 lbs. of chlorate of potash is added, and the steam turned on; 80 lbs.
of sulphuric acid, diluted with a like weight of water, is then
gradually added. The matters are allowed to stand for a short time, and
are then decanted into another vessel, and again boiled up with free
steam, and treated with a like quantity of diluted sulphuric acid. The
bees'-wax is then decanted into a receiver, and is ready for use. The
bees'-wax may, before undergoing these processes, be combined and boiled
up with a hard fatty acid, and then treated as above described.

CHEMICAL EXAMINATION OF NAPLES SOAP.

A. Faiszt has submitted this celebrated shaving soap to analysis. He
states that it is made by saponifying mutton fat with lime, and then
separating the fatty acids from the soap thus formed, by means of a
mineral acid. These fatty acids are afterwards combined with ordinary
caustic potash to produce the Naples soap. He found that 100 parts of
this soap contained

MANUFACTURE OF SOAP.

The removal of the duty from soap, and the consequent emancipation of
this branch of industry from the tender mercies of the Excise, has given
a fresh impetus to the manufacture of this important article of daily
use, and enabled some processes to be practically carried out in
England, which, previous to the removal of the duty, could not be
adopted in this part of her Majesty's dominions.

It will doubtless appear strange
