New Microscopes and Accesso- 

 ries. 



This month we illustrate Crouch's 

 " Histological Microscope " the cut 

 of which is furnished by Messrs. J. 

 W. Queen and Co., of Philadelphia, 

 who are the agents for Mr. Crouch. 





J.' lU. JLU. 



The stand is advertised as "the 

 cheapest binocular made," and in 

 respect of price it lias few rivals. 



The illustration renders a careful 

 description unnecessary ; there are 

 so few parts to the stand that 

 nothing we can say would be of 

 special service to the reader. 



The stage is quite thin, and the 

 object-carrier does not add much 

 to its thickness. The tube which 

 receives the sub-stage accessories is 

 screwed into the under part of the 

 stage and can readily be removed 

 for oblique illumination. 



The base is sufficiently heavy, 

 graceful, and stands very hrm with 

 the body in any position ; we cannot 

 perceive that there is any super- 

 fluous metal in any part of the 

 instrument, hence it is light and 

 portable. 



The mirror-bar swings laterally, 

 thus affording ev- 

 ery facility for il- 

 luminating objects 

 with extremely ob- 

 lique light. 



With the excep- 

 tion of the base, 

 the stand is of well 

 finished brass, and 

 is, on the whole, a 

 useful and attract- 

 ive instrument. 



When inclined as 

 in the cut the stand 

 measures about 

 35c.m. -j^ iieight. 



This microscope 

 with one pair of 

 eye-pieces in the 

 case, is sold for 

 $50.00, with the 

 _ ^ addition of a one- 



__^^- ' inch and a quarter- 



inch objective for 

 $75.00. 



The monocular stand, somewhat 

 different in construction, with one 

 eye-piece and case sells for $32.00.
