Recipe for Making Arsenical Soap. 



White bar soap, soft rather than hard 2 pounds. 



Powdered arsenic 2 " 



Camphor 5 ounces. 



Subcarbonate of potash 6 " 



Alcohol 8 " 



Directions : The soap should be the best quality of laundry

 add the camphor, which should be dissolved in the alcohol at 

 the beginning of the operation. Stir the mass thoroughly, boil 

 it down to the consistency of thick molasses, and pour it into 

 an earthen or wooden jar to cool and harden. Stir it occasion- 

 ally while cooling to prevent the arsenic from settling- at the 

 bottom. "When cold it should be like lard or butter. For use, 

 mix a small quantity with water until it resembles buttermilk, 

 and apply with a common paint-brush. 



The prices charged for the manufactured article by chemists 

 who make arsenical soap to sell are out of all proportion to the 

 cost and labor involved, and every taxidermist who uses much 

 of it should by all means manufacture his own supply. 



Hendley's Enamel Garnish. Take equal parts of ether and 

 alcohol, mix them, and add one-third as much gun-cotton. To 

 every gill of this mixture add six drops of olive-oil to give elas- 

 ticity. It is a good plan to keep two bottles, one containing
