BULLOCH HISTOLOGICAL MODEL
SERIAL NUMBER: 242
Signed 'PATD. 1879, W.H. BULLOCH, CHICAGO, ILL.'. Note the Brass Gliding slide carrier stage with single pressure point. Slide holder width 3 inches. Included with the oculars and objectives as accessories is a camera lucida. The substage condenser holder and condenser are nickel-plated, which is unusual. I would like to thank Richard Marks, the owner of this instrument for photographing it and allowing me to use his images.
