TWENTY- SEVENTH EEPOET ON THE STATE MUSEUM. 



This will, in most cases, afford space enough for the exhibition 

 of the various stages and forms of a species. The specimens 

 may be glued to the sheet in the same manner as flowering 

 plants, but leaf specimens are best attached . by adhesive 

 strips, as they are apt to separate from the glue or else become 

 broken by the contraction and expansion of the herbarium 

 sheet. Adhesive plaster, used by physicians and surgeons, 

 may be cut into narrow strips and used for this purpose. 



If, in all cases of fleshy fungi that change color in drying, 

 as many of them do, a colored sketch of the fresh plant could 

 be attached to the herbarium sheet, it would add much to 

 the value and utility of the collection, but this is only practi- 

 cable when the requisite time and skill can be commanded. 

 So also, the addition of a magnified sketch of the spores of 

 all species is greatly to be desired, but can only be attained 

 by the use of a compound microscope with the camera lucida.
