Tke Climatology of Africa.—Mntk Report of a Committee consistiyig 

 of Mr. E. G. Ravenstein {Chairman), Sir John Kjrk, {the late) 

 Mr. G. J. Symons, Dr. H. R. Mill, and Mr. H. N. Dickson 

 {Secretari/). {Drawn up hy the Chairman.) 



Meteorological returns have reached your Committee, in the course of 

 last year, from thirty stations in Africa. 



Nigeria. — We are able to publish a full year's record for Old Calabar. 

 The observations, since September last, are being made thrice daily in 

 accordance with our programme. We look forward with interest to the 

 receipt of meteorological reports from Northern Nigeria, which have been 

 promised by General F. D. Lugard, C.B., and which we hope to be able to 

 publish in next year's report. 



British Central Africa. — We regret that full reports have been 

 received only for two stations, namely, Zomba, which is in the immediate 

 charge of Mr. J. McClounie, the director of the scientific department, and 

 Lauderdale, the residence of our esteemed correspondent, Mr. John W. 

 Moir. No reports from Fort Johnston have been received, and those from 

 thirteen other stations are more or less incomplete, owin^ to the occa- 

 sional absence or the illness of the observers. Dr. James E. Mackay, of 

 the London Missionary Society, whose valuable report for Kambola we 

 published last year, has, we regret to say, given up his meteorological work, 

 owing to ill health and the impossibility of finding a trustworthy native 

 assistant. He writes : ' I see no way to get regular observations, and 

 have, with great regret, resolved to gi\'e it up rather than provide unre- 

 liable and worthless reports.' 



British East Africa. — Returns from ten stations have been received 

 including three months' observations from Nairobi, to the north of 

 Machako's. The returns from Fort Smith, in Kikuyu, and from the 

 neighbouring Scottish missionary station being incomplete, we defer their 

 publication until next year, as we hope shortly to receive the returns for 

 the missing months. No report has been received from Golbanti, on the 

 Tana River. As an instance of the extent to which an injudicious exposure 

 of the thermometers may afiect the returns we refer to the ' Notes ' on those 

 received from Machako's. We record with regret the death of Mr. C. H. 

 Craufurd, one of H.M.'s Sub-Commissioners, who has at all times taken a 

 li\ely interest in the work of your Committee. 



Uganda. — The observations on the level of Victoria Nyanza having 

 been received only up till October, the publication of the results is 

 deferred till next year. 



Your Committee cannot conclude this report without expressing their 

 sincere regret at the death of their late colleague, Mr. G. J. Symons 

 F.R.S., whose valuable counsel they have enjoyed ever since their for- 

 mation in 1891. 



Your Committee propose that they be reappointed for another year, 

 to enable them to make a final report. They do not ask for a ^rant.
