highly charged with vapour is rendered incapable of 
condenfing any more; the vapours then pais on to 
the veffel K, and heat that alio. 
The liquor then that was diflilled into the veffel 
F, was mixed with the liquor of the veffels I and 
K, then being * diddled, cohabated and rectified 
flowly with flacked lime, produced a very fubtile 
penetrating fEther; it is very remarkable, that this, 
though free from acid, upon mixing it with water, 
caufed a violent ebullition. 
An expeditious method of making Nitrous /Ether 
by Diftillation, without Fire. 
(See fig. 5.) Pour flx ounces of the molt concen- 
trated fpirit of nitre, little by little, on eight ounces 
of rectified fpirit of wine, (baking the veffel each 
time in which the mixture is made. 
Then convey it by a long funnel through the 
opening of the head at C, into the matrafs A ; the 
opening is afterwards lecured by a glafs flopper ; in 
warm weather this mixture grows hot in five or fix 
minutes, and diftills in a ftream into the veffel E, 
and is over in about half an hour. Before the ma- 
trafs grows cold, a frefh mixture is put in as above, 
and fo on for five or fix times, till there is liquor 
enough diflilled. This liquor being flowly re&ified 
* Spirits of wine was ufed likewife here to condenfe the va- 
pours ; and though the diftillation was condu&ed with a very 
flow fire, yet theVpirits of wine grew very hot. Spirit of wine 
was likewife ufed to condenfe the vapours in the cohabation, but 
thev did not grow hot. 
This liquor without cohabation affords iTther, but not fo great 
a quiimity - Y y y 2 with
