THE YOUNG NATURALIST. 



[March, 



on the object, using as little pressure as possible. If these points are 

 carefully carried out, a successful mount will be the result. If the 

 balsam is not heated enough it will not set, if it is too hot when the 

 object is put in, the essential oil will vaporize, and fill the mount with 

 air bubbles ; and experience teaches me it is better to prepare a new 

 specimen, then try and get rid of these enemies to the microscopist. 



I am not aware that this subject has been gone into before in the 

 way I have described, but Mr. Tugwell says, he has seen some 

 mention of it in one of the magazines, but I have failed to find it. 

 There was also a paper read before the Lancashire and Cheshire 

 Entomological Society by the late Benjamin Cooke, touching on the 

 anal apendages, this paper I have not been able to see, but I believe 

 he simply examined the part with the aid of a strong magnifying 

 glass, and, as far as I know, no attempt has previously been made in 

 this way for utilizing the anal apendages as a means of discriminating 

 the species of Lepidoptera. I have endeavoured to make myself 

 plain, but dealing with parts, the names of which are almost unknown, 

 it is possible some of my statements may not be as clear as might be. 

 I shall be very glad to give any information in my power, and answer 

 any questions. I shall also be very thankful for any material to 

 work upon, there are many nearly allied species such as A crony da p si 

 and tridens, Bryophila perla and glandifera, Notodonta dictea, and dictaoides, 

 Caradrina blanda and alsines, and many others, which if I were in 

 possession of genuine specimens of the male, I could have an 

 opportunity of examining. There must be lots of damaged speci- 

 men lying in duplicate boxes, of no value to the owners, but being 

 capable of being put to true usefulness if they fell into a worker's 

 hand.
