MICROSCOPES, 



THE FLOWER MICROSCOPE. 



Fig. 746. THIS ms t rumen t (Fig. 746) consists of a 



lens mounted in a brass frame, with a stem, 

 having an ivory or ebony handle, the whole 

 about three and a half inches long. Through 

 the stem there is an arm, which is made to 

 slide smoothly, and at one end a socket, in 

 which moves stiffly a steel rod having a 

 small milled-head at one end, and a sharp 

 point at the other, which may be set at 

 different heights, and turned about while 

 viewing the object. To use the instrument, 

 the object to be viewed is placed on the 

 point, and the arm moved backwards and 

 forwards in the stem till the object is seen 

 distinctly. This instrument is convenient 

 for viewing leaves, flowers, and parts of 

 plants, &c., and may be used without the 

 arm, as a hand magnifying glass. The 

 whole is packed in a small box. In the 

 best kind there is an additional lens, which 

 may be used singly or both together, producing a consider- 

 able increase and variety of power ; also a pair of small 

 forceps for holding any object, is connected with the point ; 

 either of which may be used as may best support the ob- 

 ject. In using the microscope, it should be held in such 

 a way that the most light should shine on the part viewed. 

 Price, with one lens and point, $1.12^. 

 " with two lenses and forceps, $1.50.
