OBJECTIONS TO USE OF CYANIDE. 

 E. J. Smith, Sherborn, Mass. 



I find this objection to cyanide. With some species of insects cyanide is 

 objectionable because it causes them to rigidly contract the wing muscles so that 

 it is hardly possible to set them. This is particularly true in the case of bees and 

 wasps ; their wings can no more be moved than they could be if no joints existed. 

 Hesperidae are also very difficult to spread if killed in this way. Ether will leave 

 them very flexible and is consequently much better on that account. Ammonia is 

 also a perfect killer in this respect, but must not be used on any green colors. To 

 use either of the above a little cotton should be wet with the liquid and put in 

 the bottle. A small vial of the liquid should be carried along so as to replenish 

 frequently. Sometimes moths that are too rigid to set when first killed will relax 

 if kept twenty-four hours. In order that they may not dry up they should be 

 enclosed in a tight box with a little moist cotton and some naphthalene to prevent 

 mold. Most beetles die very slowly in cyanide or other fumes, but die instantly if 

 wet with gasoline. 



It has just occurred to me that the solid carbonate of ammonia would be 

 easier and better to use, and not be liable to wet the specimens. It would last 

 longer than the liquid. A lump of it could be secured in the bottom of the jar 

 in any convenient way. 



ENCOURAGING WORDS. 



Geo. P. Engelhardt, Children's Museum The Brooklyn Institute of Arts and 

 Sciences, Bedford Park, Brooklyn, N. Y., says: 



"I have read with much interest 'The Butterfly Farmer,' Vol. I, No. 1 . It 

 is full of sound and practical advice. What a help such a publication would have 

 been to me when years ago, as a boy, I commenced making entomological collec- 

 tions. 'The Butterfly Farmer' surely ought to be on file in the Children's Museum 

 Library, so that it may be freely consulted by all. I enclose my check for a 

 year's subscription. Please send the publication direct to the Library. I wish 

 'The Butterfly Farmer' a long and prosperous future."
