PupsD should be wrapped carefully in tissue-paper or cotton-wool 

 and packed carefully in cotton-wool. 



Finally, the great art of successfid transmission of insect specimens 

 by post is to use plenty of good packing material. It is far better to 

 pay a little extra in po.stage and make sure that plenty of packing 

 material surrounds the insects sent than to skimp the packing and find 

 that the specimens have arrived broken to pieces on account of defec- 

 tive packing. 



May I say a few words as regards labelhng insects ? I put down 

 details of each specimen on a card and on the label I have only a number 

 referring to this card. 



That means that your specimens are incomplete in themselves and 

 if you send them out it is very difficult to know what the data are. 



You could make out a list and send it with the specimens. 



That is not an easy matter when you have to send out thousands 

 of specimens as we do. 



A card index is certainly a valuable accessory. You really require 

 a clerk to deal with the writing work in the case of a large collection. 



Do you prefer cork for lining the boxes ? We use pith and it answers 

 very well with us. 



I think that cork is better to work with and more permanent. I 

 certainly prefer cork for cabinets. 



I use asbestos sheets, but these are too hard to take ordinary pins. 



71.- 



-A METHOD OF PRESERVING BUTTERFLIES AND OTHER 



INSECTS. 



By Dr. E. H. Hankin, M.'A., Sc.D., Chemical Examiner to Govern- 

 ment, Agra. 



The ordinary method of preserving butterflies is not without its 

 disadvantages from the point of view of the ordinary collector. In 

 a cork-Uned store-box about a quarter of an inch of vertical space is 

 occupied by the butterfly and nearly two inches of vertical space by 

 its pin. 



My attempts at an improvement on an ordinary store-box have led 

 t o a method which may perhaps be of use in special cases. Each butter- 

 fly is movmted in an air-tight box having a glass top and bottom. The 

 sides of the box are made of a strij) of benl^fc electroplated. I submit 

 specimens of butterflies mounted in this way [exhibited]. 



I have used three sizes of boxes. The largest takes ordinary quarter- 

 plates as used in photography. The next size is fitted with these plates
