occur on the outer garments in warm weather; Trappe (1915, p. 1266) 
states that the.nits are chiefly found inside the collar; in trousers about 
the waistband, seams and fork, whilst many are discoverable beneath 
the lining. 
Although precise statements are lacking regarding the distribution 
of lice upon the clothing of British soldiers, I gather that the condition 
is much the same as that described by Legendre in French troops, 
with the addition of the Scotch kilt which has become a notorious 
depository for nits, its many folds, accessible only to lice, affording an 
ideal place for peaceful oviposition; outer garments, made of fur, 
may also become heavily infested. The statement of Peacock (1916, 
pp. 45 et seep) that clean shirts, issued to troops in the trenches, attained 
the usual degree of lousiness in two days, the lice migrating thither 
from the trousers, indicates already that the shirts showed most lice 
and that the necessity of de-lousing other garments was not at first 
recognized by those in authority. The renewal of one garment like a 
shirt is clearly of little avail if all the other clothing remains infested. 
German soldiers told Hase (xi. 1915, p. 158) that they preferred keeping 
on their dirty old greasy underclothes because these were a better 
safeguard than clean ones, stating that “if one puts on a clean shirt 
the lice are there at once.” 
If necklaces may be classed as clothing, it may be mentioned here 
that Brumpt (1910, p. 550) has seen large numbers of corf oris upon the 
necklaces of naked aborigines in Africa. 
DISTRIBUTION OF CORPORIS UPON THE BODY. 
Although, as previously stated, it has been denied that corporis may 
live upon the body and deposit its eggs upon human hair, there is 
clear evidence to the contrary. I am convinced that nits will be found 
much more frequently upon the body hair if inspection is made less casually. 
The nits upon the body hair are inconspicuous objects and may well 
escape notice. The matter is of considerable practical importance in 
its bearing on the efficacy of measures directed against lice, for the 
measures may be vitiated if lice and nits remaining on the body are 
not considered. 1 have seen corporis upon the hair of the breast and 
axilla. The evidence of the following authors, moreover, appears 
conclusive : 
Nysten (1858, p. 1180) states that in cases of heavy infestation, 
corporis oviposits on the body hair, mainly on that of the chest and arm-
