APHOEISMATA ENTOMOLOGICA. 19 



numbers are as follows: — No. 11, pi-icc sixpence an ounce; No. 13, 

 sixpence; No. 5, one shilling and threepence; No. 17, two shillings and 

 ninepence; No. 15, three shillings and threepence; No. IS, three shillings. 

 Of these, the largest-sized are only for the largest-sized Sphinges; — 

 for by all means you should incline to putting a too small in preference 

 to too large a pin into any insect; — or for putting out the antennas 

 with; being long and fine, and larger ones being incommodious for the 

 small interstices that will sometimes be found to be left among the 

 card braces. 



In no case use any but Entomological pins. "A maxim worth re- 

 membering I assure ye." 



"XOTHIN'G LIKE GLASS." 



It will perhaps have been observed that in the | description of the 

 Entomological book-boxes just spoken of, no mention was made of

 twelve-shilling box with the like, sixteen shillings. 



The glass to be the very best that can be had, flattened as for 

 picture frames.

"The most valuable discovery of modern times" — to the Entomologist — 

 is the "Applicability" of sugar to the capture of moths. The "Suggestive 

 Hint" to this mode of proceeding was doubtless furnished to some 

 thoughtful mind, by the observation of the fact, that insects of various 

 kinds resort to an empty cask in which the "Essence of slave" has
