§ 486. Slides, glass slides or slips, microscopic slides or slips. — 

 These are strips of clear flat glass upon which microscopic specimens 

 are usually mounted for preservation and ready examination. The 

 size that has been almost universally adopted for ordinary prepara- 

 tions is 25 x 76 millimeters (1X3 inches). For rock sections, slides 

 25 X 45 mm. or 32 X 32 mm. are used; for serial sections, slides 25 

 X 76 mm., 38 x 76 mm. or 50 x 76 mm. are used. For special pur- 

 poses, slides of the necessary size are employed without regard to any 

 conventional standard. 



Whatever" size of slide is used, it should be made of clear glass and 

 the edges should be ground. It is altogether false economy to mount 

 permanent microscopic objects on slides with unground edges. It is 

 unsafe also, as the unground edges are liable to wound the hands.
