A NEW OPHTHALMOSCOPE.

A NEW OPHTHALMOSCOPE. In this instrument the first noticeable feature is the construction and placing of the mirror; this not only tilts but also revolves about its own axis. The second feature is that the body of the instrument is so constructed that it can be revolved around its own axis carrying the mirror with it. This gives the mirror a third motion, first, tilting; second, revolving around its own axis; third, revolving around the axis of the body of the instrument, whereby the user can place the mirror at any desired position while the arrangement of the lenses remain undisturbed. There are two lens discs effectually covered and protected from dust and handling, one containing the following lenses: 1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 11; 12 convex, and 0.50 and 13 concave. The other disc contain: 1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 11; 12 http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png JAMA American Medical Association
