APHOKISJIATA EXTOMOLOGICA. 21 



width as the rest of it. Fill this glass jar with plaster of Pai-is up 

 to a sufficient height, namely so far as to leave sufficient depth for 

 any insects you may want to relax between the surface and the cork. 

 Pour on the plaster as much water as it will absorb^ any surplus 

 being poured off, and over it place a round piece of perforated zinc, 

 the size and shape of the orifice of the jar, the object being to keep 

 the wings of the insects from touching the wet surface; and at the 

 same time the holes in the zinc answer admirably for putting the pins 

 of the insects into, so that they are steadied, and in a manner fixed, 

 so as not to shake about if the jar is moved. 



When you have thus placed the said insects in this way, put the 

 cork or stopper tightly into the jar, and in a few hours, more or less 

 according to the size of the specimen, yon will have them excellently 

 relaxed, and that without the slightest detriment or damage; the down 

 being as perfect as if they had never been subjected to any such pro- 

 cess at all. A tin canister will answer the purpose, but not so well; 

 the jar, especially if it have a glass stopper, being so much more air- 

 tight, and the moisture being therefore the more confined. If a cork 

 be used, it should have a piece of fine kid leather round it, to make 

 it fit close; also, I recommend a basket work case to guard the lower 

 part of the jar.
