to a period of 3 to 6 months. A full description of the warbles and 

 of the symptoms produced is given, together with an account of various 

 methods of treatment. No special method of prevention is known, 

 but cow-birds {Molothrus), tick birds {Crotojjhaga) and others should 

 be protected. It is also strongly urged that the attempt to improve 

 local stock by animals imported from abroad may result in the des- 

 truction of valuable immunities and adaptations which have taken 

 centuries to become established. A lengthy bibUography concludes 

 this paper.

A collection of the Tabanidae of Hong Kong, started originally 

 by Mr. Adam Gibson, M.R.C.V.S., Colonial Veterinary Surgeon, and 

 carried on jointly with the author, has been undertaken. One 

 thousand five hundred and eight specimens have been forwarded 

 to the Director of the Imperial Bureau of Entomology and \ a 

 prehminary list dealing with 395 of these has been received, which 

 includes the following species :—Chrysops dispar, F., C. striata, 

 Wulp, Tabanm crassvs, Walk., T. ditaeniatus, Macq., T. hilaris, 

 Walk., T. hyhridus, Wied., T. indianvs, Ric, T. jucundys, Walk.,

The attempt to check the progress of East Coast fever has been 

 continued throughout the year. In the Cape Province, dipping tanks 

 have been established in several localities and the movements of cattle 

 restricted to a certain degree. Although the efforts to control the 

 disease have met with considerable success, the Province is still in a 

 precarious position, owing to the presence along its border of an 

 extensive native area in which the disease is prevalent. In the 

 Transvaal, except in the district of Piet Retief, considerable progress 

 has been made. During the year, 41 farms have been removed from 

 quarantine and only 14 fresh outbreaks have occurred. New dipping 

 tanks have been used by Europeans and natives, with gratifying 

 results. The construction of tanks in Natal has been actively carried 

 on. The Government has been empowered to estabhsh tanks on 

 the holdings of absentee owners. Zululand presents the greatest 

 difficulties ; an enormous area occupied by natives has become so 

 thoroughly contaminated that it is difficult to determine whether 

 any particular spot has become clean by lapse of time or whether 

 the disease is still smouldering there ; added to this, the use of 

 immune animals for transport purposes has contributed to the un- 

 certainty of the position. Steps have been taken to provide dipping 

 facihties for natives. Work in the Transkei has been difficult owing to 

 the great area of land occupied by native population. The whole of 

 the low-lying and coastal districts have been overrun with the disease.
