34. On the detection of Potash by the oxide of Nickel— 
As the method of Harkorts for the detection of potash is 
but little known to chemists, and as it promises great advan- 
tages, especially in sae gy, we think it right to state 
erzelius says of it in the new edition of his treatise 
on the blow pipe, about i: appear. According to this che- 
mist, the method of Harkorts has answered perfectly to the 
trials to which he had subjected it, to ascertain its correct- 
ness. It is sufficient to dissolve the oxide of Nickel in bo- 
rax, and to add to the vitreous matter a little nitre, feldspar, 
or any potassuretted substance, to obtain immediately a 
glass of a very distinct blue color. The presence of soda 
does not prevent this reaction. Among the preparations of 
Nickel, we may employ the nitrate or oxalate of this metal. 
It must not however contain cobalt, as that phen the glass 
a brown color,—Ferrusac’s Bull. Juillet, 1828. 
35. Description of a very simple Apparatus for saturating 
ny liquid with gas and without loss of the flud, by M. Hes- 
oo —The gas is to be enclosed in a bladder, which is to be 
connected by a hollow cylinder with an elastic tube, (a gut, 
or something of that kind.) This tube is to be adapted to 
a bottle containing the fluid to be impregnated, and which is 
not to be quite full of the liquid. In the neck of the bottle 
adjust a cork pierced with two holes, into one of which fas- 
ten a tube, which shall pass downward — the fluid, and 
over ex hole place a valve opening upw 
the bladder is pressed, the gas ance through the 
tube into the fluid, and rising to the top, it ascends through 
the valve to be again pressed downwards into the fluid, until 
the absorption is complete.—Jbid.
