ENTOMOLOGICAL INSTRUMENTS, &C. 537 



be transfixed and put into a pocket-box lined with cork. 

 Some use an oblong deep chip one, with paper pasted 

 over it, and lined at top and bottom, the top being con- 

 venient for setting small moths. But this you will find 

 not easy to open when you have an insect in one hand ; 

 and it is too deep for the pocket. I generally use a 

 mahogany one, about 7-J- inches by 4?J and 1 deep in 

 the clear, corked only at the bottom*, and opening by 

 pressing a spring, which can be done with one hand. 

 This will contain as many of the above insects as you 

 will usually take in a day's excursion. When travelling, 

 you should provide yourself with larger store-boxes, to 

 receive at night the fruit of the day's hunt. These may 

 be 18 inches square and 2J deep, corked at top and bot- 

 tom; which should be of equal depth, and fit very closely, 

 to keep out Acari^ &c. Entomologists have recourse 

 to various ways of bringing home insects for immersion. 

 For the larger ones, you must be provided with a num- 

 ber of small boxes, the lids of which are not liable to 

 come off in the pocket. If it can be done, it is best to 

 have only a single insect in a box. If you have several, 

 those that are predaceous in their habits will probably 

 devour the rest : and besides, if you open a box to put 

 in other insects, generally one or two of those before 

 imprisoned in it will make their escape. It is best to put 

 the boxes containing an insect in one pocket, and the 

 empty ones in another. If your boxes are numbered, in 

 a small memorandum-book, which you should carry for 

 the purpose, you may make any remarks as to the food, 

 station, and habits of any insect you may take, inserting 

 against them the number of the box or phial that contains 

 it, and it will be ready for future use. For the smaller
