Leitz Travelling Microscope.
This instrument (fig. 3) packs into case 21 by 14
by 7 cm., and weighs only 4 Ib. It will be seen
from the figure that to set up the instrument for
use, the mirror and stage have to be attached, and
the tube which carries the ocular must be unscrewed
and reversed. It will also be seen that it has
rack-and-pinion coarse, and micrometer-screw fine
adjustment; the only point not quite clear in the
illustration being the method of folding the foot.
This foot is a very ingenious one, consisting of
two solid rectangular bars of brass lying against
each other when the instrument is packed, but which
can be opened out so as to make an angle of some 40
degrees, in which position they are firmly held by
a spring-catch, and as there is no inclination,
this gives ample stability.
