and practical experience, a number may be chosen as having given 
satisfaction. Details concerning the remedies and their mode of applica¬ 
tion will be found by turning back to the reference numbers hereafter 
cited in brackets. The remedies and methods that appear most useful 
are marked with an asterisk (*). 
Remedies against head-lice : Acetic acid is of great use as an aid to the 
removal of nits (364). Alcohol, with or without the addition of camphor 
(373). Benzine (370) and Xylol (474, also as an ointment), but both are 
highly inflammable. Carbolic acid solution* (375), also as pomade and 
with oil (378-9). Chloroform-water (388). Sublimate vinegar* (414), 
Calomel pomade (419). Oleate of Mercury and Ether (420), to be used 
with caution. Oil of Sassafras (441), objectionable because of its smell 
and that it soils pillows, etc. Oil of Turpentine* (01. tereb. rect. 442), 
smell agreeable and does not soil. Balsam of Peru ointment alone (446, 
where impetigo present), or with sulphur (447). Petrol and Methylated 
Spirit (449). Petroleum* alone (450, a household remedy) or with olive 
oil (451), an objection is the smell. Petroleum-vinegar (456). Veratrine 
ointment (J %> 460). Staveacre oil or ointment (463). Treatment in 
most cases has to be repeated because of the nits remaining unaffected. 
Remedies against lice on clothing and on the body: (1) Acting by their 
vapour on effects exposed in closed spaces are Benzine (370), Carbon 
bisulphide (384, for furs especially) and Xylol (474), but all very in¬ 
flammable. Creolin* (391), not inflammable, non-toxic, but odour dis¬ 
liked. Hydrocyanic acid gas (402), highly toxic but penetrates fast and 
evaporates quickly, therefore it might be used with safeguards. Sulphur 
dioxide is not recommended for reasons specified (465). (2) Acting 
chiefly by contact, the following Insecticide solutions, 1-2 %, are 
recommended for washing down floors, steeping infested clothes, boots 
and other leather objects (for 15 minutes or more), and for use by men 
when bathing, being combined with soft soap to aid in cleansing: Cresol- 
soap* (395), Cresol-petroleum-soap* (396), Lvsol-soap* (406), also 454-5, 
or Crude Carbolic acid solution* 1 . These soap preparations will doubt¬ 
less act as well as the much advertised Vermijelli (473); they can be 
similarly applied. 
For spraying or application to the skin or body hair when infested: 
Petroleum (450, with care), also applied as an ointment. For the treat¬ 
ment of infested clothing when being worn, and supposedly to repel 
lice: Crude Naphthaline and Soft Soap*, ironed into the seams which 
have been folded back after smearing the mixture into them; the
