paper with hot glue, about the consistency of cream, the 

 glue being laid on the specimens with a hair pencil. 

 The newly-mounted sheets should be placed between 

 waste paper or newspapers, and pressed over-night, 

 before they are finally retouched and placed in the Her- 

 barium. Straps of gummed thin paper may be fastened 

 over the thicker parts of the specimens, to prevent 

 them breaking loose from the paper when accidentally 

 bent. 



The mounted specimens belonging to the same genus, 

 or a part of them if the genus be a large one, may be 

 placed in a folded sheet of a stronger and coarser paper 

 than that upon which the specimens are glued ; upon this 

 cover, at the bottom, the name of the genus and of its 

 Natural Order may be marked. The genera should be 

 arranged in their Natural Orders, the Natural Orders in 

 their respective Divisions and Classes, and the whole
