DESCRIPTION

412This microscope is from another private collection and I am greatful to the owner to allow me to photograph it. This is the Bulloch Professional No. 2 as pictured in the 1890 catalog. It arises from a flat tripod on a single relatively short pillar. This original Bulloch microscope has a slightly shorter pillar than the later Meyrowitz stands. It is signed on the top side of the foot: 'W.H. BULLOCH, CHICAGO ILL' in an oval pattern. On the underside of the foot it is signed: 'PATD. 1879, 412'. There is a decorative damascened finish to the stages and the side plate of the limb. Silvered scales are present for each of the two swinging tailpieces. Like my earlier Professional model, this Professional No. 2 was supplied with two stages, a mechanical stage and also a glide stage, however the mechanical stage is the later version with vertically projecting controls which allows full 360 degree rotation. There is also a condenser with conical wheel of apertures and four objectives by various makers. There is also a Bulloch compressorium, and two eyepieces. The substage is raised or lowered by rack and pinion. Unlike the later Meyrowitz Biological No. 2, this microscope has no silver calibration of rotation on the foot and no indicator for the fine focus control. In addition, as would be consistent with its earlier date of manufacture, this microscope has a brass draw tube rather than a nickel-plated one and the side plates of the limb, though damascened, are brass rather than nickel plated.

bulloch prof 2 HISTORY OF THE PROFESSIONAL NUMBER 2 MICROSCOPE

This microscope, which is identical to the Biological No. 2 model in the 1890 catalog, except for tube length, was not offered until some time after 1880, perhaps as late as 1889.
