Seltzer water . 
The vessel thus prepared, is set on b , in the vessel, and the top is 
screwed on immediately. In the course of three hours, the water 
in the vessel may be let off. The saturation or impregnation will 
be found to equal the water made in Nooth’s machine. But Mr. 
Cloud says, that the strength of Water made in his apparatus was 
equal to that prepared by the assistance of the forcing pump, 
which is a costly and an expensive mode. I intend to have a pipe 
to run from c. to the bottom of the vessel, so that the gas may pass 
through the water, in its ascent from the bottom. It is plain that 
the pressure is given, by confining the gas in a small compass, 
and the necessity it is under of combining with the water, or of 
breaking the apparatus. To avoid the latter, the vessel should 
be strong and well made. On ours, we had 15 iron hoops. I 
hope, that, on further trial, the apparatus may be found to super- 
sede the complicated one with the forcing pump, and the glass 
one of Mr. Nooth. 
As to the aerated waters generally, I am of opinion, that every 
family should have an apparatus of the kind, in order to make 
them at any time ; for the purpose of medicine, and salutary beve- 
rage. I found them in a recent complaint of more service than 
any other preparation. Owing to extreme debility, no medicine 
or food would stay on my stomach until I drank the seltzer and 
soda waters ; and I am of opinion, that by their use, sickness may 
be avoided, and of course health preserved. 
I am sir, your’s, See. JAS. CUTBUSH.

Remarks by the Editor . 
Mr. Cloud's and professor Patterson’s machine for making 
seltzer water, I saw in operation at the mint. The water was 
strongly impregnated with carbonic acid, and sufficiently so. I had 
one made on the same plan a few months afterward ; but I could 
never succeed in making the water sufficiently aerated. I shew- 
ed mine to an intelligent man of this city, Mr. Jones, who wished 
to make the seltzer and soda waters for sale. He had one made 
lately with every precaution, but his too did not succeed. Certain- 
ly the principle and the plan of Mr. Cloud’s machine are very 
simple and in theory sufficiently efficacious, but I am at a loss to 
discover what our want of success is to be ascribed to, unless it he 
t© defect in workmanship. T. C.
