 1866), Belgium, Holland, Sweden, Switzerland, and others.

Micro Cyanide Bottles. 



By Charles Stevenson, Montreal, Que. 



Mr W. D. Kearfott, in his suggestions on collecting Micro- 

 Lepidoptera recommends "the common test-tubes, which can 

 be purchased in any drug store," for use as cyanide bottles 

 (Ent. News, xv, 4, p. 128). These, as he states, are very 

 fragile, and necessitate great care in handling ; for in breaking 

 (which they will often do with the pressure of inserting the 

 cork), they are liable to badly cut the hand or maim the fin- 

 gers, and probably produce serious results if the wound could 

 not be treated immediately, as mentioned. This drawback 

 can be overcome by using a test-tube not generally heard of 

 outside a chemical laboratory, usually called " ignition tubes," 

 made of Bohemian infusible glass. These can be obtained in 

 the size recommended. They have a thick wall and are very 

 strong. 



They also have the advantage of having the mouth much 

 more flared. They cost more, about ten cents each, but are 

 worth it when one runs the risk of having his hand in a 

 bandage for many days by using the common tube — not a 

 very desirable circumstance in the midst of the collecting 

 season, especially to a student of micros. Druggists do not 

 usually stock them, but they should be obtainable from any 

 dealer in chemical apparatus.* 



Another suggestion, — corks have a faculty of disappearing 

 at inopportune moments. By attaching the cork with a piece 

 of string to the tube, this cause of much worry, perhaps loss of 

 valuable specimens, and inelegant language would be avoided. 



* The writer will gladly supply fellow entomologists unable to get 

 them, with an address where they can be obtained.
