VII. Thofe of the laft divifion (aptera) are in 

 general, fubjecls which fhould be kept in fpirit. 



When in fearch of infe£ls, we fhould have a 

 box fuitable to carry in the pocket, lined with 

 cork at the bottom and top to flick them upon, 

 until they are brought home. If this box be 

 ftrongly impregnated with camphor, the infefls 

 foon become flupefied, and are thereby pre- 

 vented from fluttering and injuring their plu-

 different fizes of infe£ts. 



In hot climates, infe&s of every kind, but 

 particularly the larger, are liable to be eaten 

 by ants and other fmall infects, efpecially be- 

 fore they are perfectly dry ; to avoid this, the 

 piece of cork on which our infecls are fluck in 

 order to be dried, fhould be fufpended from the 

 cieling of the room, by means of a flender firing 

 or thread ; befmear this thread with bird-lime, 

 or fome adhefive fubflance, to intercept the ra- 

 pacious vermin of thefe climes in their paffage 

 along the thread. 



After our infecls are properly dried, they may

 boxes mould be covered with pitch, or green 

 wax, over which paper may be laid ; or, which
