 and there the hogs are dipped. The dipping should be repeated

For lice on horses and cattle (Fig. 336), zenoleum is used at the 

 strength of twelve tablespoonfuls to every gallon of water, applied 

 with a stiff brush or spray pump or sponge. Every part of the body 

 should be washed thoroughly and the application repeated in eight
