This miniature simple microscope measures about 28.5 mm in greatest diameter and 40 mm high at a minimum. It has several interesting features. There is a glass bottom and the upper part containing the optics can be unscrewed to allow one to put an opaque living subject like an insect inside. There is also a slot in the barrel to accept slides which are held in place by pushing up the bottom part. When a slide is not in place this piece is pushed all the way up thus closing the slot. The telescoping eyepiece can therefore focus on a slide, or when pushed in further, can focus on the livebox portion. The images are good considering the low price of the instrument at the time. A small slide with specimen is included.
HISTORY OF THIS MICROSCOPE
This design, found in periodicals from 1879 and 1880, was sold both by magazines as a subscription premium, and also by mail-order and other retailers. It was but one of a great many designs for an inexpensive small microscope sold for use by those interested in studying insects and plants without great expense. It is one of the more flexible designs allowing the use of slides and also its own built-in live box. The biggest drawback is the lack of openings to illuminate an opaque specimen. It is designed mainly as an instrument to view transparent or translucent specimens.

I am a member of the Quekett Microscopical Society and The Microscopical Society of Southern California. I have contributed numerous articles to the Journal of the latter, and have also written articles about orreries published in the Journal 'Rittenhouse,' the American Scientific Instrument Society Journal. Many other additional original articles I have written about microscopes and their history, can be found on my web site at www.microscope-antiques.com/articles.html. I have been a meteorite collector for decades and all of my meteorites are guaranteed to be absolutely authentic.
