compounds ; secondly, an anopheles gang, to drain 

 pools and depressions in back yards and streets. The 

 members of the gangs instructed the householders upon 

 the danger of harbouring lar\'a?. The drains were 

 kept brushed out. The result of the cleaning up and 

 drainage was an observable diminution in the number 

 of mosquitos. 



Dr. Logan Taylor, as the result of a second and 

 independent visit, drew up a report upon the sanitary 

 condition of Cape Coast Town. 



The late Dr. Dutton in 1902 visited the Gambia, 

 and reported upon its antimosquito measures. 



Lieut.-Col. Giles was also sent out by the Liver- 

 pool School, and reported upon antimalarial measures 

 in Sekondi, the Goldfields, and Kumassi, and there 

 have been many more expeditions of a similar nature 

 (see Appendix). 



In 1904 I also visited, in conjunction with Drs. 

 Evans and Clarke,^ Freetown, Bathurst, and Conakry 

 in the French Guinea, and reported upon the sanitation 

 and antimalarial measures then in force. Wq found 

 that the inhabitants had commenced to put into practice 

 the teachings of the previous expeditions, and that they 

 realised it was possible to protect themselves from the 

 anophehnes by adopting the precautions taught by 

 Ross. We found that mosquito nets were more gener- 

 ally used, the water cisterns screened, and the drains 

 better looked after. In other words, there was a 

 distinct improvement over the condition reported by
