This microscope, now
for the first introduced by us, is made portable, to
meet the want of a compact instrument for use at the
seaside, etc. It folds into a space about 6 1/2x3
1/4x2 3/8 inches. It is of brass throughout,
handsomely finished, has broad and firm tripod base,
axis for inclination to any angle, plane and concave
mirrors, with adjustments for obliquity. For
illumination of opaque objects, the mirror bar may be
removed and replaced in the reverse position, thus
bringing mirrors above the stage. The instrument
stands 12 inches high when draw-tube extended (as
shown in illustration).Society-screw, carrying an
adapter with an achromatic object-glass of 4/10 inch
focus, dividing to 8/10, which gives powers ranging
from 40 to 140 diameters.
3077 and 3079 have a
good fine adjustment, moving the stage, as in our
Holmes Class microscope
