DRY-MOUNTING FOR OPAQUE OBJECTS. 195 



The result of this very simple, quick, and easy process is, that 

 the object is enclosed in a cell at once air-tight and water-tight, the 

 adhesion of the wax to the wood, and the covering glass to the wax, 

 strengthened by the adliesive cover paper, ensuring immunity from 

 damp, while I have never known an instance in which any object was 

 in the least affected by contact with the wax itself.
