LICE.
One might infer that habits of personal cleanliness did not prevail in England two centuries ago, judging from the terms of the following prescription, which seemingly takes as a matter of course that the patient could at any time obtain the insects needed:—
“For the cure of sore eyes ... take two or three lice out of one’s head; put them under the lid.”—(“Rare Secrets in Physicke,” collected by the Comtesse of Kent, London, 1654, p. 75.)
The author of this work knows, from disagreeable personal experience and observation, that the Indians of North America very generally were addicted to the disgusting practice of cleaning each other’s heads and putting all captured prey in their mouths. Such an office was considered a very delicate attention to be paid by a woman to her husband or lover, or from male friend to male friend, while on a campaign. No instance was noted of the use in a medical sense of these troublesome parasites.
