Methods of controlling body lice, which can be used when the 

 appliances are available, include baths, fumigation with steam, carbon 

 bisulphide or sulphurous anhydride ; a 5 per cent, cresol soap solution 

 kills lice rapidly, but a 1 per cent, solution of corrosive sublimate has 

 no eftect. If the men can be stripped, a dry heat of 160° F. will kill 

 lice and nits in 10 minutes ; the seams of clothing may advantageously 

 be passed through the flame of a candle. Where the clothing cannot 

 be removed, the best preventative is to wear silk underclothing. 

 A 5 per cent, naphthaline ointment, ether, benzine and xylol are 

 recommended, but the mere dropping of these substances into the 

 clothing is not of much use. Aniseed oil is effective owing to its 

 exceedingly unpleasant odour.

An alcoholic solution of oil of bergamot, 10-15 per cent., may be 

 rubbed into the clothing or a small bag full of cotton wool soaked in 

 this liquid may be worn round the neck. The cost of oil of bergamot 

 prohibits its use on a large scale and, as an alternative, naphthaline 

 may be put in the bag and sprinkled over the clothing or the body 

 may be dusted with it.

The author has for years obtained excellent results against lice with 

 rectified turpentine used as a spray or applied with wads of cotton wool 

 after dilution with alcohol. Experiments were also made with 

 ointments containing 50 per cent, of turpentine, lanoline, vaseline and 

 ceresin. Lice exposed to pure turpentine in tubes died in 15 minutes, 

 and with the ointment in 40 to 45 minutes.

The vapour of carbon bisulphide is an excellent agent for kilUng 

 lice ; 100 grms. per cubic metre in a closed vessel will kill both lice 

 and nits in a night. Sulphurous anhydride prepared by burning 

 sulphur or carbon bisulphide is not recommended, as its action is 

 slow, and it damages the wool in the clothes. Coal gas has no effect, 

 but a 5 per cent, cresol soap solution will kill the nits in half an hour. 

 A hot flat-iron is very effective and 10 minutes' exposure to a tempera- 

 ture of 160° F. kills the nits with certainty. Insect powders are useless. 

 An ointment containing 5 per cent, of naphthaline is strongly 

 recommended, but it must be applied freely.
