 threads of the clothing but it was found that both lice and eggs were

The crab-louse, Phthirius pubis, which is nearly as broad as long, 

 lives in the armpits and pubic regions of the body. 



The common lice on cattle, swine, dogs and cats belong to the family 

 H&matopinidce. These lice have long probosces and the eyes are vestigial

is found principally on the neck and shoulders of mature cattle. It is of 

 a bluish-slate color and about f of an inch long. Sodium fluoride applied to 

 the infested places with a tin shaker and then rubbed in among the hairs

The dog-louse, Linognaihus piltferus, has a broad abdomen and a com- 

 paratively short proboscis (Fig. 145). The hog-louse, Hcematopinus suis, 

 is the largest louse affecting domestic animals and is common on swine, 

 especially if their quarters are neglected and allowed to become un- 

 reasonably filthy.
