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 1\ inches by 44 and l£ 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 c 2\ 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 
u 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 readv for future use. For the smaller
