THE SKIN 4o5 



quantity is sufficient for one animal, and should be applied to the 

 infested areas, repeating the wash in ten days' or a fortnight's time. 

 A tablespoonful of soft soap added to the mixture improves it very 

 much. Mercurial ointments, arsenical sheep-dips, and tobacco 

 washes, are to be strongly condemned, as I have seen large numbers 

 of cattle poisoned by their use in such cases.
