other cheaper and equally efEective dips can be obtained. But in 

 winter and spring, when dipping is apt to be dangerous, its application 

 with a dust-gun would prove efEective, easy, and not expensive, having 

 regard to the small quantity necessary for each animal. One 

 'pplication is sufficient, as the substance is retained in the hair long 

 enough to destroy any lice returning to the host. 



Sodium fluoride cannot apparently be relied on for use against 

 aucking lice.
