and capture of the Mohammedan chiefs. He. states, that when 
pursuing them across the Beloor to Badakshan, two large lakes oc- 
curred in his route, called Ifil-Kol, and Polon-Kol,—that they lay 
between two parallel ridges of mountains, on the western slope of 
the Beloor,—and that, from the latter of the ridges, Badakshan 
may be seen. ‘This eastern Badakshan cannot therefore be 4° W. 
_ of the Beloor, but, on the contrary, on its western declivity, not 
far from the central range. Sherefeddin, in his life of Timoor, men- 
tions the kings of Badakshan, which implies that there were more 
cities and districts than one called Badakshan. | 

ART. Il.—-Experiments to show that two or more streams of 
Electricity may be made to circulate, in opposite directions, upon 
the same wire, without neutralizing each other. By K.T. Kemp, 
Esq. Lecturer on Chemistry, &c. &c. 
1. A srream of electricity from a single copper plate, C, four 
inches square, (Plate III. Fig. 1.) and one of zinc, Z, constituting 
the simple galvanic circle, was made to circulate along the wires 
A B, which were so connected with a needle apparatus, as to form 
a continuous metallic wire, passing below a magnetised needle. The 
needle stood nearly at right angles to its natural position. The 
stream of electricity, as shown in the figure, circulated in the direc- 
tion of the arrows,—from the copper to the zinc. 
A stream of electricity from a battery, CD, of sixty pairs of 
plates, two inches square, was, at the same time, made to circulate 
along the wire in an opposite direction to the stream from the 
single pair of plates. Not the slightest effect was produced on the 
deviation of the needle. 
When the streams of electricity from the battery were made to 
circulate along the wire, in the same direction as that from the 
single pair of plates, a very slight increased effect was produced. 
To show that electricity did actually circulate from the battery, 
the wire I K was cut, and the extremities inserted into water, and 
decomposition was instantly effected, which continued during the 
experiment. 
2. A stream of electricity from a powerful electrifying machine 
was likewise passed along the wire, below the needle, in an oppo- 
site direction to that from the single pair of plates. No effect was 
produced, neither did any effect take place when the stream went 
in the same direction with that of the simple galvanic circle. 
When an electric battery was discharged through the wire con- 
ducting the electricity of the single pair of plates, no effect was 
‘produced, either when it was circulating in the direction of the 
current from the single pair of plates, or when opposed to it. * 
* This experiment was exhibited before the Royal Physical Society, at its 
meeting of Tuesday 26th January 1829.
