The author considers lice to be the carriers of Volhynian fever, a 



disease which usually terminates favourably even in the absence of 



treatment, but which incapacitates soldiers for considerable periods. 



The causal agent is a parasite very similar to that of typhus.

 The results of experiments with a number of liquids and powders 



recommended against lice are recorded. Many of them proved 



unsatisfactory, cresol-soap solution, 5 per cent., being the most 



effective.

The author's summary of this paper is as follows :— The spirochaetes 



are able to multiply to a considerable extent in lice fed on the blood 



of an infected patient. In the louse the spirochaetes retain their form, 



motility, virulence and staining properties. Certain developraental 



forms of the spirochaete are not found in the louse. Transmission of 



recurrent fever from the louse to man does not appear to result from 



its bite, but the infection of man is thought to be due to the crushing 



of the louse and the entry of the spirochaetes through abrasions of the 



skin or mucous surfaces.

 This paper records the presence in the intestine of the clothes louse 

 [Pediculus humanus] of a hitherto unknown parasite. It is sometimes 

 very abundant and is perhaps allied to Babesia or Leishmania. This 

 parasite, Strickeria jiirgensi, gen. et sp. n., apparently occurs during 

 part of its development in the louse and seems to be sometimes trans- 

 mitted to man in large numbers. Further research is required to 

 determine whether it is the cause of disease.

Icterus epidemicus.] — Deutsche Med. Wochenschr., Berlin, xlii, 



no. 16, 20th April 1916, pp. 482-483. 



During the summer and autumn of 1915, the author, in studying a 



widespread epidemic of Icterus epidemicus, obsei-ved that a decrease 



in the number of cases coincided with a reduction in the number of 



house-flies, which may perhaps be carriers of this disease.
