Objects Seen Under the Microscope.

XXIV.— CRYSTALS. 



The crystals of many of the salts in common use make 

 very pretty objects when seen under the microscope 

 and some of them are easily prepared. It is well to be- 

 come acquainted with them. Take a little table salt, 

 dissolve it in water and place a drop on a slide, spread 



it evenly and let it dry. In a few minutes many square 

 crystals may be seen (fig. 1 m). As a rule the longer 

 the crystals are in forming the larger they will be. Al- 

 um treated in the same way gives crystals as shown in 



flg. 1 h.
