and bromide of potassium. Keep patient •\\arm and quiet; 

 administer strong tea. Give artificial respiration. (Reference 

 Handbook of Medical Sciences.) 



Barium carbonate: the antidote is any soluble sulphate, such 

 as Epsom salts, Glauber's salt or alum. This should com- 

 pletely neutralize the poison. (Henry Leffmann.) 



In any case of poisoning, a physician should be called as soon 

 as possible. 



Rat Deodorants. • 

 Rats sometimes die within the walls of a dwelling whether 

 poisoned or not, and the resulting odor is, to say the least, 

 unsuited to the domicile of civilized man. 



A compound of zinc and chlorine, commonly known as 

 chloride of zinc, which has had a reputation for many years as 

 a deodorant, antiseptic and germicide, may be useful at such a 

 time. While the value of this compound may not be great for 

 the two latter purposes it is e^¥ecti^■e in deodorizing. It is 

 "capable of combining with hydrogen sulphide, ammonia and 

 other offensive products of putrefaction, and forming com- 

 pounds that are comparatively odorless.'"^ It is more effective 

 in neutraHzing animal than vegetable odors. "Pickett" says 

 that the following will purify the air in any room: "In one 

 pint of boiling water dissolve half a dram of nitrate of lead; 

 now dissolve two drams of common salt in a bucketful of cold 

 water, then mix the two; dip a good-sized cloth in it and hang 

 in the room."- Xo deodorants have been tested by the Massa- 

 chusetts State Board of Agriculture, but in case of necessity 

 either of the above may prove satisfactory. 



Rat fumigation. 

 Carbon Bisulphide in the Burrotcs. — For killing rats by 

 wholesale in their holes in the ground, in ditch banks, dikes, 

 river banks, levees, shores or dams, carbon bisulphide is the 

 best agent known. ^ Unlike traps and poisons it does not require 

 the co-operation of the rat. Carbon bisulphide is sold as 

 liquid but quickly takes a gaseous form when liberated. It is
