Geiffith, B. H. — A beautiful slide. 



[" Heat a slide until it will melt a small portion of a menthol pencil as it is 

 drawn evenly back and forth over a perfectly clean sui'face. Do not use 

 more heat than necessary to melt the material evenly. Then as it com- 

 mences to crystallize, arrest its progress frequently by passing the slide 

 quickly over the flame of your spirit-lamp. Soon the crystallization will 

 be completed, a little at a time, and a very desirable slide will be the 

 result."]
