This vapor is deadly to insects in all stages, ex- 

 cept the egg stage. If the infested drug be 

 placed in a tight vessel, after removing the dust 

 and debris caused by the attack of the insects, 

 and a quantity of bisulphide of carbon, suffi- 

 cient to charge the vessel with vapor, intro- 

 duced, any inSects in the vessel will be killed. 



The Pharmacopoeia, in speaking of the pres- 

 ervation of ergot, says: "It should be pre- 

 served in a close vessel and a few drops of chlo- 

 roform should be dropped upon it from time to 

 time to prevent the development of insects. '» 

 I should say that chloroform probably ranks 

 next to carbon bisulphide as an insecticide for 

 this purpose. 



This paper would not be complete without 

 recording the list of those drugs which were not 

 attacked by insects — drugs exposed to exactly 

 the same conditions. Those in the following 

 list were kept in the same room and in the same 

 kind of containers, and exposed to precisely the 

 same atmospheric conditions as those mentioned 

 in the preceeding list.

The alkaloid of Calycanthus glancus has been 

 discovered and first extracted by Dr. Eccles of 

 Brooklyn, he has obtained it in crystals which 

 from their high refractive power sparkle like 

 diamonds. Dr. Eccles exhibited some of these 

 when reading his paper, announcing the dis- 

 covery, at the April meeting of the New York 

 Section of the American Chemical Society. This 

 alkaloid has the highest refractory power of 

 any known organic substance. A nitroso-com- 

 pound of calycanthine is thalleiocanthine; this 

 forms dark colored salts that in dilute solution 

 are a brilliant green. No therapeutic applica- 

 tion of the alkaloids has yet been announced.
