Galvanic Experiment. 
touched the zinc circuit, and produced electro-magnetic effects 
by these means also. This is likewise reducible to a collateral 
galvanic circuit; for I have proved, by experiments published 
two years ago, that a galvanic circuit may be made for a short 
space, by two plates of zinc and a liquid, provided that one of 
the plates be brought into contact with the liquid before the 
other. 
Art. II. — Remarks made during part of' a Journey from 
Christiania to Bergen., in the Summer o/’1821. By Profes- 
sor Hans TEEN 
On the 22d of June I went from Christiania to Kongsberg, 
in order to go westward into Telemarken, to visit the celebrated 
Riukand Fall, and the not less remarkable Gousta Field, which, 
so far as I know, is the highest mountain in the south of Nor- 
way. From that I intended to proceed northward through 
Nummedal to the borders of Hallingdal, and thence to Eidford 
in Befgenstift. As geographical measurements had not extend- 
ed to this part of the country, I expected to find considerable 
inaccuracies in Pontoppidan’s map, and therefore took with me 
a sextant, chronometer, barometer, and thermometer, to settle, so 
far as it might be in my power, any geographical points. I 
was besides interested in making some magnetical observations 
in the west of Norway : for the western variation of the magnetic 
needle is greatest towards the we^, and its inclination and inten- 
sity are greatest towards the north. As experience had taught 
me that mountains have a certain influence on these three mag- 
netic phenomena, I wished to examine this matter more narrow- 
ly in the mountainous district of* the west. For this purpose I 
carried with me a small azimuth compass, an instrument for 
measuring the declination, and an apparatus with a pendulum 
for determining the strength of the magnetism of the earth at 
different places. 
At Kongsberg, on theSSd of June, we found, by a series of 
observations, the latitude of the place 59° 40' 8.8" : the chrono- 
meter gave the difference of time W. of Christiania 4' 15 J". The
