With a battery of 30 jars, containing 4000 square inches of 
surface, the needle deviated to the amount of 30°. is was 
lined to draw off the electricity. One of these points was 
applied to the outside of the battery, and the other, held by a 
glass support, was brought to the knob of one of the jars. 
Vhen within the distance of 4 or 5 centimetres, the deviation 
_ commenced, and at one or two centimetres it advanced to 
23°, was then weakened, and ceased entirely after a continu- - 
ance of 5 seconds. The experiments were repeated in pres- 
ence of Arago, Ampere and Savary. The want of success 
with previous experiments by common electricity, is attribu- 
ted to a defective insulation, and to the want of sufficient 
care in obtaining a continued -current of electricity. This 
appears to be eflected by drawing the current from a battery 
by means of fine points.—Ann. de Chem. Sept. 1826.

sulphuric acid is distilled, says M. GMELIN, let the receiver

phuric acid will be deposited in crystals upon its surface, and 
liquid acid, less dense than that which remains in the retort, 
will collect in the bottom. It appears that during the distil- 
lation, the acid is divided into two portions, one of which 
yields its water to the other.—Ann. de Chem. Juin, 1826-
