Camera for Producing Enlarged Images of Microscopic Ob- 

 jects.* 



WITH FRONTISPIECE. 



Owing' to the improvements in microscope objectives 

 and in pliotography, it is practicable to produce magni- 

 fied photographic images of microscopical objects wliich 

 are not only interesting to the microscopist, but are also 

 of importance to the pathologist and histologist in mak- 

 ing a record. 



We illustrate photo-micrographic apparatus recently 

 completed by Mr, 0. Gr. Mason, microscopist of Bellevue 

 Hospital, and for many years secretary of the American 

 Microscopical Society. 



This apparatus will receive an objective of any power 

 and produces images on a 3i by 4i plate. The apparatus 

 is very compact, being only about two feet in length. 

 It is all mounted on a single base board, so that it may 

 be removed bodily if it becomes necessary to shift its 

 position. 



The camera box is rigidly attached to the standard of 

 a microscope of the usual form, so that the box can be 

 placed horizontally or inclined at any desired angle. 

 Adjustments are made which provide for any required 

 distance between the objective and the sensitive plate, so 

 that the desired amplification may be readily secured.
