PEDICULUS CAPITIS
(Common Louse).
It is scarcely necessary to give a description of this species which is sufficiently known; we shall content ourselves with indicating the principal characteristics which distinguish it from the other vermin living on the surface of the human body. The louse is of an oval form; flattened, longer than the crab-louse; its head is very small; its thorax is composed of three not very distinct rings; the abdomen is all of one piece, rounded off on the sides; it is ash-colored, whereas the crab-louse is entirely white. The lice which have been made use of in our provings, were taken from the head of a healthy child of five years.
Even before undertaking this experiment we expected to derive from it important results. We entertained the belief that nature pointed out to us the louse as a specific for the hereditary psora, in which belief we were strengthened by the fact that psorin develops the lice-malady in healthy persons. And we are now prepared to affirm that we have found the louse one of the most useful agents in diseases of children. We offer the following pathogenesis with a sincere pleasure which none but those who devote themselves to such patient investigations, can appreciate.[2]
