AVONFORj ON BUTTERFLY SCALES. 83

In obtaining the scales, I have found the best way to 

 examine a wing is to lay it on a clean slide, place another 

 upon it, and apply a moderate amount of pressure. Upon 

 separating the slips, plenty of scales from cither side, in their 

 relative positions, will be found on the glass slides. If re- 

 quired to mount, a ring of varnish may be run round, and 

 when nearly set, a glass cover being laid on the slide, it re- 

 quires only a finishing coat when dry to make it ready for the 

 cabinet. 



Note. — My observations have been confirmed by the examination of 

 many tropical and Continental species of tlie above-mentioned families ; and 

 since January of thisj'ear (18G8), 1 have become aware that Mr. J . Watson, 

 of Manchester, has read papers on the " Plumules," before the Manchester 

 Literary and Philosophical Society, and is engaged, as I learn by corres- 

 pondence, in publisliiug a work ou that subject, to be illustrated by GOO 

 figures.
