11th. — For procuring shells the collector should 

 be furnished with one or two strong knives ; a 

 hammer and chisel for those which dwell in rocks ; 

 tin boxes and calico bags for specimens; a large iron 

 ladle perforated at the bottom, or a strong hoop 

 with a shallow bag of wire-gauze, made with a 

 socket to fit on the end of a rod, for examining the 

 bottoms of streams for small shells ; a hoop net of 

 coarse canvas for similar purposes; and a kind of 

 dredge to fit, by means of a socket, on the end of 

 a pole or jointed handle, might be added for such 

 species as lie imbedded in mud. 



12th — Large-mouthed, stoppered glass jars fitted 

 in cases for specimens to be preserved in spirits, or 

 wide-mouthed pickle-jars, which when well corked 

 and coated with cement, will be found very useful 

 for the same purpose ; and a good supply of small 

 stoppered bottles for Annelids, and other delicate 

 objects, which should, as far as practicable, be pre- 

 served separately. 



Lastly. — One or two additional pairs of scissors 

 might, with advantage, be added, also the following 

 articles, viz., needles, thread, silk, twine of different 

 sizes, a few brushes both of camei's-hair and of bristle, 

 card-board, coarse brown and thin white paper, 

 calico, common muslin, bags of the two last named 

 materials of different sizes for fish, &c. Chloroform 

 for killing insects, a good supply of spirits, camphor, 

 a quantity of alum, some pieces of cork, bungs ; and 

 finally a quantity of tow and cotton, to be regulated 

 by the destination of the collector.
