A DEMONSTRATION HERBARIUM 



233 



This particular apparatus is a modification of the widely used 

 devices for the display of commercial products and was made to 

 order by the Multiplex Display Fixture Company of St. Louis, 

 and similar apparatus may be obtained from them. 



In practice this method of displaying herbarium specimens has 

 proved to be a decided advance in effectiveness and convenience 

 upon the customary methods.
