A disease to which young chickens in Fiji are particularly liable is 

 known as chicken-pox warts or sorehead. It is commonly thought 

 to be caused by mosquito bites, the sores arising from the scratching 

 of irritating spots. As nothing is definitely known regarding the 

 connection between mosquitos and the disease, it is suggested that 

 some birds should be kept in mosquito-proof enclosures in order to 

 see whether the disease would arise and spread among them.

Nicotine solutions are said to be very efficacious in curing mange in 

 animals. For sheep, a lotion is made containing 0- 12 or 0- 13 per cent, 

 of nicotine ; to this is added a weight of soda crystals double the weight 

 of the pure nicotine.

 beige. — A nn. GemUonx, Brussels, xxvii, no. 7, July 1921 , pp. 239-242. 



The parasites of poultry and other birds in the Belgian Congo 

 include : — Filaria gallinarmn, Theil., causing intestinal filariasis in 

 about 80 per cent, of fowls and having for its intermediate host the 

 termite, Hodotermes pretoriensis, Full. ; the Acarid, Cnemidocoptes 

 mutans, Rob., causing mange of the feet, especially in native fowls ; 

 the tick, Argas persicns, Oken, which apparently causes death in 

 poultry, although the presence of Spirochaeta gallinarum has not been 

 recorded ; Mallophaga, causing phthiriasis ; the flea, Echidnophaga 

 {Sarcopsylla) gallinacea, Westw., which produces a high mortality 

 among fowls, generally infesting the head in large numbers, and having 

 dogs and cats for alternative hosts ; AmUyomma hehraeum, Koch, 

 causing heartwater, frequently ending fatally, in turkeys ; the Hippo- 

 hoscid^y , Lynchia maur a, mg., transmitting Haemoprotens columbae 

 in pigeons and very common in pigeon lofts. 



A tour of the eastern and western provinces of the Belgian Congo, 

 undertaken after the writing of this paper, has disclosed the following 

 additional poultry parasites : — the Acarid, Dernianysstis gallinae ; 

 a new species of Reduviid ; Lipeurus ? heterograplius ; and the Acarid, 

 Sarcoptes laevis, causing mange. 



These parasites are responsible for a certain mortality, and are the 

 cause of epizootics, many of them, in the absence of their preferred host, 

 attacking other animals, including man. A note will be published 

 shortly on the remedial measures that have been used with success.

In the summer of 1919 the cockroach, Periplaneta americana, L., 

 was remarkably abundant in Egypt, presumably in consequence of the 

 presence of large supplies of food for the army. Spreading from the 

 depots, storehouses and cellars the cockroaches entered houses, 

 particularly during the night through open doors and windows, thus
