Microscopy at the Columbian Exhibition.

The display of microscopes and accessories at the World's 

 Fair, though so scattered as to be difficult to see without con- 

 siderable trouble, is probably the largest ever made at any ex- 

 position, and well worth all the trouble necessary to find it. 

 The displays are scattered among the American, English, 

 French, German and Italian exhibits, most of them being in the 

 great Liberal Arts building. The American displays of scienti- 

 fic instruments are in the North gallery of this building, and 

 the finest show of microscopes is that of the Bausch & Lomb 

 Optical Company. They have a good place in section E, and 

 dispday 40 microscopes, microtomes and magaifying glasses, be- 

 sides sterilizers, and numerous specimens of prisms, condensers 

 and photographic lenses. Their newest form of microscope 

 stand is an imitation of the well-known German horse-shoe 

 model, which seems to be liked very much notwithstanding its 

 inherent awkwardness. Another style which they have be- 

 gun to make is the Wenham radial, which seems to have some 

 striking advantages, though it is slow in coming into popularity. 



Next to theB. & L. Co., is the Gundlach Optical Company, with 

 an excellent assortment of lenses, and a collection of stands on 

 the German model. A little to the west is the Mcintosh Opti- 

 cal Company, with a good selection of the lower-priced grade of 

 instruments. Near them is the booth of Queen & Co., with 

 their well-known style of stands, and also some specimens of 

 Carl Reichert of Vienna, for whom they are American agents. 

 The house of E. B. Myrowitz of New York, who manufactures the 

 handsome form of stand made popular by the late W. H. Bul- 

 loch, is represented by three excellent specimens, which are dis- 

 played in the exhibit of the section of Microscopy of the Chi- 

 cago Academy of Sciences. Among microscope makers, Joseph 

 Zentmayer of Philadelphia, one of the oldest and best-known 

 men of his line, is unfortunately not represented. Grunow and 

 McAllister, once so well-known are also absent, but for better 

 reason, as they no longer maker either instruments or objectives. 

 Of objective makers, Spencer and Wales are both conspicuous 

 for their absence, so that, there is a serious gap in the list of
