THE ATMOSPHERIC CHURN. 
S the age advances, so do the contrivances for render- 
ing a less amount of manual labour necessary in 
some of those procedures which have been going on in 
almost the same style since their very first institution. 
Amongst improvements of this description we may men- 
tion an apparatus by which the making of butter is effected 
upon an entirely new principle, it being produced by 
atmospheric action, the air being forced in intermittent or 
continuous currents into the midst of the milk or cream 
contained in the cylinder. This is accomplished by work- 
ing the tube or plunger up and down within the cylinder, 
keeping its disc or flange always below the surface of the 
milk or cream. The plunger being raised, a partial vacuum 
is created beneath the surface of the fluid, which causes the 
air to rush down through the hollow stem with great force. 
When the plunger is forced downward, the valve at the 
upper end of the tube will be closed, and the air below the 
plunger will be rapidly expelled through the fluid, by 
means of which, the globules containing the butter will be 
expanded, opened, and the butter liberated. 
By this invention, the long and tedious process of churn- 
ing is entirely obviated, and butter is made from fresh milk 
in ten minutes. Notwithstanding that this invention has 
but recently been introduced into England, its novelty, 
practical value, and economy have already commanded an 
attention that promises for it the highest place among the 
implements of domestic economy. 
This unique apparatus was awarded the first prize at the 
City of London Industrial Exhibition, and has received 
extensive notice and patronage from the nobility and gentry. 
We recommend this churn to the notice of our readers, 
not only for its practical, but its economical worth. 
DISINFECTANTS. 
HE air we breathe, the water we drink, and also must 
be added the water we breathe in the form of dew and 
fog, are the vehicles by which the material causing epidemic 
disease is carried into the system. Disinfection must be 
directed to each of these carriers of poison, if it is to be
