Body Lice.—The Body Lice are larger than the head lice and are commonly found upon the body. This type has bands across the back.

Crab Lice.—They usually develop in the seams of clothing, however, the eggs have been found upon the hairs on the body’s surface. They live in concealed portions of the clothing where the skin is most conveniently reached, where the various bites are to be found most often, as around the neck, across the shoulders, the upper part of the back, around the waist and outer side of the thighs.

TREATMENT. All clothing worn should be boiled and gone over with a hot iron to destroy them. A hot bath should be taken by the person annoyed by the parasites. Bathing suits should be carefully boiled as they often become infested with the eggs and body lice from a person who may have worn the suit and had them, upon his or her clothing or person.

In some ways that treatment has changed substantially.  Some of the medicines and shampoos have definitely improved.  But who knows maybe in another 100 years they’ll have diet pills that include a treatment for lice and crabs.
