A simple, inexpensive and efficient microscope lamp

An Improved Microscope Lamp.

The new inclined binocular microscopes when used with high-power objectives require much light to illuminate adequately the field of view. At least three times the light is necessary as for a similar optical combination on a monocular instrument. The ordinary opal bulbs even when over-run do not provide sufficient illumination, and of course with them there is no possibility of employing a ligh...

An inexpensive method of slit-lamp photography.

Depth measurement with the slit-lamp microscope.

The sagittal distance of ocular structures can be obtained with a slit-lamp microscope providing the movement of the slit-lamp can be measured. A simple device consisting of a pointer attached by a spring clip to the axle of a Haag-Streit 900 slit-lamp is described. The pointer rides over a scale which slides with the slit-lamp. Comparisons of anterior chamber depth and lens thickness showed a ...

A Simple and Inexpensive Flea-Proof Cage

a platform of wire mesh (4 to the inch) is arranged inside the cage. A removable lid about 1^ inches deep is prepared. A third of this lid is cut away and fine-meshed (40 to the inch) good quality copper or brass gauze is fixed by soldering, or better still by soldering a strip of tin over the free edges. A shallow (about \ inch deep) removable tray is fitted near the bottom of the tin and the ...
