Perhaps the most frequently used instrument of an ophthalmologist is a good binocular loupe.
Frequently it has been my misfortune not to have a loupe with me when away from the office, since I could not ordinarily carry one because of its bulk, as all loupes with which I was acquainted were very bulky. So I had alterations made on a Beebe loupe which would not add to its weight (this loupe was fitted with my correction). The loupe will fit in an ordinary number 5 spectacle case.
The obvious advantage of this will be instantly apparent to any ophthalmologist or to other physicians who need such an instrument.
The makers of this instrument, George H. Pilling and Son Company, Philadelphia, will be able to supply these folding loupes.
