Schrauer's Physicians Stand
A very solid and
serviceable instrument of this type is the
Physician's Microscope of L. Schrauer of New York,
shown in Plate VIII A. The body is large, admitting
an ocular of 32 mm. in diameter, and is adjustable
by means of its drawtube to any length from 16 to
25 cm or more. The diaphragm is inserted in the
stage; and a glass sliding stage is provided, in
the Zentmayer style held in position by a spring
with ivory tip. Such a stage has a smooth motion
and wide range, is available for use with the
Maltwood finder (a photographed scale of great use
for recording the exact location of mounted objects
on a slide and enabling them to be promptly found
when wanted again), and is unaffected by those
reagents which might in certain cases, mar a brass
stage. The joint by which this stand is inclined
has a set screw for securing it in any position.
The disk of the swinging mirror bar is graduated as
in all the higher class stands of this type, for
the purpose of determining the obliquity of
illumination or the angular aperture of
objectives.
