are to be slaughtered, skinned, or used in any manner, nor is the 

 milk or other parts of them to be sold. The cadavers of animals 

 which have died or been killed on account of rabies are to be either 

 chemically destroyed, or, after the skin has been destroyed, buried. 

 Autopsies upon such cadavers can only be made by approved veteri- 

 narians. It is the duty of the police to select the spot where such 

 dogs shall be buried, or otherwise destroyed. The straw of the 

 kennels, wooden utensils used about them, and wooden dog-kennels 

 must be burned. Stall-utensils of other animals which have been 

 rabid, and killed, must be cleaned with hot lye-water. Iron utensils 

 must be highly heated. The stables must be cleansed, the walls and 

 floors cleansed with hot lye-water and chloride of lime." 



Disinfectants. 



" Potash and Soda. — Potash-lye is to be prepared by cooking 

 one part crude potash with ten of water, and by adding gradually 

 one part of slaked lime. Instead of potash, four times the quantity 

 of wood-ashes may be used. Soda-lye is to be prepared in the same 

 manner. These preparations are more suitable for cleansing wood- 

 work. 



" Freshly-slaked lime is to be used in a dry form for covering 

 cadavers, or as lime-water for washing over walls, mixing with ma-

 a strained solution of one part lime to sixty or eighty water. 



" Common Salt and Saltpeter. — Hides, flesh, intestines, bones, 

 horns, claws, etc., may be treated with these salts, by laying them 

 in layers or piles thoroughly mixed with them, or by placing them 

 in a strong solution of the same. 



" Chlorine may be used in different ways : 



" As gas, in the disinfection of stables. Gas is easily and quickly 

 prepared by pouring double the weight of muriatic acid upon chlo- 

 ride of lime, or equal parts of sulphuric acid upon the same. Or it 

 can be prepared by pouring strong (commercial) muriatic acid upon 

 a quantity of small pieces of peroxide of manganese, or by pouring 

 strong sulphuric acid upon a powdered mixture of three parts com- 

 mon salt and two of peroxide of manganese. A solution of chlo- 

 ride of lime can be made by mixing one part of the same with ten 

 of water. 



" Hyperinanganate of potash and soda are mixed with water, 

 and four to five per cent solutions used for washing the hands, in-
