Note on the preparation of the smaller Bivalves 

 for the Cabinet. — I have adopted a plan which I think rather 

 an improvement on Mr. ColUer's method (J.C., vol. iv., p. 54). 

 After extracting the animal I place them on a setting-board of 

 cork, somewhat similar to those used for insects. A strip of 

 cork, say i in. or i| in. wide, with a v shaped groove cut down 

 the centre with a cabinetmakers' rasp, and finished off with 

 glass-paper, I find answer the purpose admirably, the shells 

 being placed in the groove beaks upward. A setting-board a 

 foot long will take a good lot, and they are easily observed and 

 compared in this position. For the larger shells any convenient 

 crevice, such as the spaces between the strips of a greenhouse 

 stage, will answer well. — Wm. Jeffery, Ratham, Chichester, 

 March 9th, 1885.
