The following was
extracted from the Illustrated Price List of
Microscopes for Sale by T. H. McAllister
Manufacturing Optician, No. 49 Nassau Street, New
York 1876. McAllister was a New York sales agent for
Zentmayer microscopes.
ZENTMAYER'S U.
S. ARMY HOSPITAL MICROSCOPE
Was designed and
constructed for the U. S. A. Medical Department in
1863, but it has since been very much improved. The
Stand is sixteen inches high when arranged for use.
Body, fine adjustment, and draw-tube are precisely
the same as those of the "Intermediate". The bar is
supported by one stout pillar. It has plane and
concave mirrors, mounted similar to the former. The
stage is made of a piece of plate glass,
perforated in the centre, with brass mountings to
receive the objects, and stage forceps; has also a
stop for Maltwood's finder, and is kept down on the
stage plate by a spring with an ivory pointed screw,
similar to the revolving stage of the "Intermediate".
The accessories are attached to a short tube below
the stage, which may be removed when oblique
illumination is required. Simplicity, steadiness, and
convenience are the merits of this Microscope.
The binocular
arrangement differs from the former only in tbe mode
of adjusting the eye-piece for the distance of the
eyes of different persons, which is accomplished by a
connecting bar.
