RECIPE FOE ARSENICAL SOAP. 



Camphor 5 ounces 



Arsenic, in powder 2 pounds 



White soap 2 pounds 



Salts of Tartar 12 ounces 



Lime, in powder 4 ounces 



Cut the soap in thin small slices, as thin as possible ; put 

 them in a pot over a gentle fire, with very little water, taking 

 care to stir it often with a wooden spoon : when it is we]l 

 melted, put in the salts of tartar and powdered chalk. Take 

 it off the fire, add the arsenic, and triturate the whole gently. 

 Lastly, put in the camphor, which must first be reduced to 

 powder in a mortar, by the help of a little spirits of wine ; mix 

 the whole well together. This paste ought then to have the 

 consistence of flour paste. Put it into glazed earthen pots, 



* Methylated spirit, of full strength, answering every pin-pose, may be pur- 

 chased, free of duty, at certain druggist's and other shops, at a cost of about 4s. to 

 5s. per gallon.
