The few notes that have been published on the infestation of domestic 

 animals by Leptus autumnalis nearly all refer to the dog, so that it 

 might be supposed that this is exceptional. The author has however 

 observed that throughout the autumn nearly all the sheep and goats 

 out at pasture in the Canton of Grisons are infested. Beyond 

 causing great irritation no harm is done. A bibliography of six 

 works is given.

This paper is intended to provide officials engaged in combating 

 sleeping sickness in Kamerun with accurate information as to the 

 distribution of the disease. The coast became infected with sleeping 

 sickness in the seventies and the disease penetrated to the Sanga 

 region towards the end of the eighties or early in the nineties, it being 

 considered improbable that an old focus of infection already existed 

 there. Both Njong and Dume were infected in the nineties from Sanga 

 and the author does not support the view that sleeping sickness has 

 existed in Kamerun since early times. Its incidence is characterised 

 by sudden outbreaks, with intervals of slow spread, which accounts for 

 the difficulty in locating it and for the conflicting opinions current 

 regarding its dangerous character. The accounts from Sanga and 

 Njong especially show that after decades of comparative quiescence 

 violent outbreaks take place. It is therefore incorrect to assume that 

 the infection will die out of itself. The disease follows the march of 

 European civilisation, being spread by trading factories and govern- 

 ment posts. It first follows the rivers and then extends along the 

 traffic routes. All the information obtained by the French as to the 

 part played by Glossina in the Congo region is gathered together. 

 The view that Glossina jMljjalis is not the cause of epidemics is con- 

 sidered premature. The striking contradiction between the remarlc- 

 ably small numbers of Glossina and the epidemic character of sleeping 

 sickness may be ascribed to the fact that the Glossina in the north 

 of the Sanga region chiefly depend on man as a source of food, while 

 in the south they feed on big game.

 Louse in the Spread of Typhus.] — Med. Klinik., xii, no. 18, 30th 

 April 1916, pp. 480-488. 



The distinctions between head and body lice [Pediculus capitis and 

 P. humanus] are discussed, as well as the question of the transmission 

 of typhus by the former, on which point no final conclusion appears to 

 have been reached.
