The Microscope. 209 



image on a sensitized collodion film. " This is given as a com- 

 pound word. Worcester gives practically the same definitions. 

 It is proper then for Prof. Cox and Mr. Walmsley to show us 

 their Photo- Micrographs, while Mr. Ayres, of Jamestown, N. Y., 

 shows us his Micro]! holographs. 



Mi< rophotographs. This calls to mind the beautiful speci- 

 mens of work in this line that Mr. Ayres exhibited at Cleveland. 

 He has some of the most charming charms we have ever seen. 

 His work is superb and many of our readers, we are sure, will 

 avail themselves of the opportunity he offers in our advertising 

 pages, and will allow him to make microscopical specimens of 

 themselves. 



Photograph of the American Society. Mr. Ryder, of 

 Cleveland, has forwarded us two prints from the negatives taken 

 at Lakeside, and to those familiar with the beautiful work of 

 this artist it is only necessary to say that it fairly represents his 

 acknowledged skill in this branch of work. The larger print is 

 8x15 and neatly mounted. There are seventy-four members in 

 the group and each face is clear and well defined. The smaller 

 print is 4 x 8 and is also sharp and clear. Still the larger print 

 is to be preferred, if a good view of each of the faces is desired. 

 The larger prints, well mounted, can be obtained for one dollar 

 each, with ten cents extra for packing; the smaller ones for 

 thirty cents each. Parties should address J. F. Ryder, 239 Su- 

 perior St., Cleveland, Ohio. 



Exhibits at Cleveland.— There was a fine display of Micro- 

 scopical goods by several dealers and the members took advan- 

 tage of this in many ways. 



Mr. Walmsley exhibited a few microscopes, including the 

 new " Star " pattern. He gave his special attention, however, 

 to his new photographing apparatus and took a number of orders 

 for the same. It is, in our opinion, the best pattern in the mar- 

 ket. 



Messrs. Bausch & Lomb had a full line of their goods on 

 hand, and made a most brilliant display. Especial attention 

 seemed to center around their "Physician's" and " Universal" 

 stands, while a host of accessories came in for their share.
