Bacot (A). Wood Tar Oils Jor the Destruction o8 Lice {Pediculus 



humanus) on Hair-clad Areas.— 5n7. Med. J I., London, no. 3177, 



19th November 1921, p. 853. 



As the light wood-tar oil previously recommended as a culicifuge 



[R.A.E., B, vii, 72-74] is no longer obtainable, samples of various 



proprietary preparations of a similar type were tested for their 



efficiency in destroving Pediculus humanus. Nearly all of them gave 



equally good results. The oil must be applied liberalh' so that the 



Hce are completely immersed in the droplets ; it should be used neat 



or diluted with some other oil, and no absorbent material should come 



in contact with the treated area for an hour if possible. Greased or 



waxed paper or rubber-surfaced articles should for preference be used
