THE MICROSCOPE. 



compound microscope ? It is this : in the simple 

 microscope you look directly, through the lens, at 

 the object; in the compound microscope you do not 



look directly at the 

 object, but at its 

 image, which has 

 been magnified by 

 another lens placed 

 between the ob- 

 ject and the lens, 

 or "eye-piece," 

 through which you 

 are looking. Of 

 course, great mag- 

 nifying power is 

 thus obtained. 



Here is a figure 

 of a microscope; 

 it represents Na- 

 chet's smaller com- 

 pound microscope. 

 From a careful 

 study of this figure 

 you will soon be 

 able to learn the 

 parts of which it 

 consists, and will 

 gain a general idea 

 of what a com- 

 pound microscope 

 is. It stands, as 

 you see, on a broad foot, a, out of which a pillar, , 

 arises ; at the top of this is a joint, h, supporting the 

 stage, c, and another pillar, d, which carries the body, 

 / with which it is connected by a transverse arm, e. 

 The body slides up or down within the ring of the trans- *
