| This Galvanoscope is not listed in the various editions of Davis'
Manual of Magnetism in my collection, but it certainly looks like
a piece of Davis apparatus. The cut shows a Davis astatic
galvanometer of the same general construction being used to detect
the current produced by a thermo-electric junction. It is not completely
astatic, as Davis points out that the instrument should first be oriented
with the needle in the same plane as the coil. This example is at the University
of Mississippi museum.
