 sonted. 



Of Eniilitih makers, three are rcpresenteil : Beek iV: Heck. W. 

 \Vatso!i iV S«>tis. ami Ross. Tlie first named has the largest ex- 

 hil)it and makes a really fine display, adheriii}.; in all material 

 points to the styles so long known. Watson's exhibit is smaller, 

 hnt he has a novelty, the Van Ileurck pattern, which combines 

 a nnmher of conveniences, and partakes more of the English 

 of the han German model. Ross only shows three instruments 

 of the well-known Koss-Jackson model of stand. 



In the French dejtartment, Nachet makes by fai the best sliow- 

 ing. but his exhibit is scarcely worthy ofhim. He makes line 

 stands and accessories, and they were* worthily shown at the 

 Paris Photographic Convention last September, but here the 

 large phot<vmicrograiihic camera is absent, and its place is sup- 

 plie<l by a small and ill constructed one. The stands are badly 

 arranged and the objectives are limited to a single series shut 

 up in a case. There are, however, a few novelties, one being a 

 stand with a stage nearly 6 by 9 inches, for examination of sec- 

 tions across a whole brain and the like, and another being spe- 

 cimens of "palladiumized" stand or of brass ]»lated with palla- 

 dium. They resemble oxidized brass and give a fine ell'ect. 

 Vion Freres have a large number of cheap stands, Teigne and 

 Moreau show a few of the conventional forms, and J. Duboseq, 

 the well-known instrument maker, exhibits a fine vertical and 

 projecting microse<»i)e. 



Italy also appears in the list with a case of stands and objec- 

 tives manufactured by F. Koristka of Milan. The objectives 

 include an apochromatic of 2 mm. of 140 N. A. but botli lenses 

 and stands are a close and servile imitation of German }>atterns. 



But by far the most scientific display of microscopes and ac- 

 cessories of all kinds at the Fair, is that of the famous Zeiss es- 

 tablishment of Jena. It is located in the Northwest portion of 

 the gallery in the Electricity Building with the exhibit of the 

 German Society for Mechanics and Optics of Berlin, the society 

 not being able to get the necessary space in the Liberal Arts 

 Buildings. There seems to be something of the proverbial 

 " yankee " energy and i)ush in the way the Zeiss business is con- 

 ducted, and it is shown in the exhibit. Every kind of instru- 

 ment made by the firm is to be seen here, from the simplest
