iron clamps, and the lid grooved to receive a fillet 

 from the lower part, made for additional protection, 

 and partitioned into spaces for the store-boxes to 

 slide into. These cases should not be made incon- 

 veniently large, as it would be better to have two or 

 more of them of moderate dimensions, that they 

 may be perfectly portable. 



7th. — A plentiful supply of solid-headed pins, of 

 all sizes, for insects, &c. 



8th. — Nets and other implements for the capture 

 of insects. The simplest is the hoop-net, consisting 

 of a ring of strong wire, with a socket to fit on the 

 end of a rod, which latter might, with advantage, 

 have an additional piece provided with a socket, or a 

 screw-ferrule, if preferred, to enable the collector to 

 use a longer or shorter handle, as required. Three 

 or more hoops, ten inches or a foot in diameter, 

 might be adapted to the same rod, one hoop to have 

 a bag-net of gauze twenty inches deep for catching 

 insects on the wing, particularly Lepidoptera ; an- 

 other of cheese-cloth, fourteen inches deep, for sweep- 

 ing, and for Coleoptera ; a third of muslin, of the 

 same or even less depth, for obtaining aquatic insects ; 

 and a fourth of fine net, to be used as a kind of 

 landing-net in seeking for water insects, small fish, 

 and crustaceans. The same rod might serve as a 

 handle for the scoop and nets requisite for obtaining 

 shells from the bottoms of pools and streams. 



The fly -net is another much used, and is perhaps 

 the best for some purposes, particularly " mothing." 

 In form it resembles that used by bat-fowlers, and
