The Botanist's Microscope 



Designed to be used with 

 the Botanical Text- 

 Books published by 

 the American Book 

 Company. 



This convenient instrument, 

 devised and manufactured first 

 for the use of the students in 

 Harvard University, has 

 given so great satisfaction there, and elsewhere, that we have 

 made arrangements by which we are able to offer it to students 

 in all parts of the country at a very reasonable price. 



A thousand things about forest, field, or garden afford 

 objects of intense interest for daily study, and a good Micro- 

 scope furnishes the best means for unlocking their secrets. Of 

 this Microscope the late Dr. Gray said : "I do not think any- 

 thing better can be made for the money." 



This Microscope is attached to a box, one and a half inches 

 high and less than four inches long, into which it is neatly 

 folded when not in use. The needles are used for dissecting 

 flowers or other objects too small to be otherwise handled for 

 analysis.
