4 MOUNTING INSECTS IN FLUID 



specimens of small size, I have frequently 

 used a collecting tube in place of a box, 

 pinning the specimen securely to the under- 

 side of the cork. 



If insects are to be sent in fluid, then the 

 tube or bottle containing them must be filled 

 with the preservative quite up to the cork, so 

 that the air is entirely excluded. To effect 

 this, the vessel should be filled to overflowing, 

 and the cork worked in by pressing it from

 contents. I have given up the use of cotton- 

 wool in the tubes, as recommended by Mr. 

 Halford, as I found that the legs and other 

 parts of insects adhered to it and frequently 

 became detached. 



TRICHOPTERA with immensely long and slender 

 antennae, sent to me by Mr. Jack Henderson 

 from so far off a land as the Federated Malay 

 States, have arrived in perfect condition, owing 

 to the precaution of filling the bottle quite full 

 having been observed. 



From time to time I have been asked to 

 describe the method by which specimens in 



K*O the Halford cabinets at the Fly Fishers' Club 

 lub> are mounted. I propose to devote a few lines 

 to the subject in this chapter. 



Glass blocks. The specimens are mounted in glass blocks, 

 which may be obtained from Messrs. F. H. 

 Taylor & Sons of King's Cross. The blocks have 

 to be made specially for the purpose, and con-
