and using ready-prepared dips. The arsenical dip is not usually 

 warmed or heated in the vat. 



It should be remembered that arsenical dip is a poison, and precau- 

 tion should be taken to prevent injury to man or animal. When it is 

 handled and used with proper care it is a safe and effective remedy. 

 Care should be taken not to get the clothing wet with the dip, and the 

 hands should be washed frequently to prevent possible absorption of 

 arsenic. 



Freshly treated animals should be held in the draining pens or 

 other suitable place until all surplus dip has drained off. (Figs. 34 

 and 35.) If allowed to drain where pools of dip collect from which 

 the animals may drink, or if the pasture or feed becomes soiled with 

 arsenical dip, losses are liable to occur.

LIME-SULPHUR DIP 



Proprietary brands of liquid lime-sulphur may be purchased, and 

 many of them are equal to or even better than the homemade product. 

 Manufacturers have also placed on the market a product commonly 

 known as dry lime-sulphur, made by evaporating, in vacuo or in the 

 presence of an inert gas, concentrated lime-sulphur solution to which 

 a small amount of cane sugar has been added to act as a stabilizing 

 agent. Dry lime-sulphur is readily soluble in hot water, and it is 

 being extensively used as a dip for animals and as an insecticide for 

 plants. Prepared dips should be diluted and used in accordance with 

 instructions printed on the label of the container. Lime-sulphur dips 

 are efficacious and dependable remedies for mange, but they are not 

 effective against lice and ticks.
