pursued : take the corks of common wine bot- 

 tles, and divide them into pieces of about three- 

 eighths to half an inch in thickness, and glue 

 them to the bottom and top of the box at a 

 distance of about an inch and a half from each 

 other. Care must be taken always to pass the 

 pin sufficiently deep into the cork, so that no 

 sudden jerk will remove or displace the insects 

 thus transfixed. It may be necessary to sug- 

 gest, that in the event of making an extensive 

 collection of the insects of any country, it is 

 advisable to have the boxes made uniform, and 

 of one size, for the convenience of packing in 

 chests, which should be rendered, by paint and 

 pitch, perfectly secure against wet and damp ; 

 the boxes ought also to be previously examined, 

 and well saturated with spirits of turpentine, and 

 a sufficient quantity of camphor should be secured 

 to prevent the insects from being injured by der- 

 mcstes, &c. The edges of the boxes should be 

 covered with paper pasted on them, to exclude 

 the air and dust.
