Microscopy at the Columbian Exhibition.* — Mr. H. L. Tolman 
has the following interesting notice of that part of the great exhibition 
at Chicago which ought most to interest our readers : — “ The display 
of Microscopes and accessories at the World’s Fair, though so scattered 
as to be difficult to see without considerable trouble, is probably the 
largest ever made at any exposition, 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 scientific 
instruments are in the north gallery of this building, and the finest 
show of Microscopes is that of the Bausch and Lomb Optical Company. 
They have a good place in section E, and display forty Microscopes, 
microtomes and magnifying glasses, besides 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 notwith- 
standing its inherent awkwardness. Another style which they have 
begun to make is the Wenham radial, which seems to have some striking 
advantages, though it is slow in coming into popularity. 
Next to the Bausch and Lomb Company is the Gundlacli 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 
Optical 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 
Beichert 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. Bulloch, is represented by 
three excellent specimens, which are displayed in the exhibit of the 
section of Microscopy of the Chicago 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 make 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 Microscope-makers 
of the country which ought to be best represented. 
Of English makers, three are represented : — Beck and Beck, W. 
Watson and Sons, and Boss. The first named has the largest exhibit 
and makes a really fine display, adhering in all material points to the 
styles so long known. Watson’s exhibit is smaller, but he has a 
novelty, the Van Heurck pattern, which combines a number of con- 
veniences, and partakes more of the English than of the German model. 
Boss only shows three instruments of the well-known Boss-Jackson 
model of stand. 
In the French department, Nachet makes by far the best showing, 
but his exhibit is scarcely worthy of him. He makes fine stands and
