Station has for a student of zoology, and especially for one who like myself had just finished his University course. Although original research is doubtless the main object of most who go to Naples, still it is impossible to over-estimate the value of the knowledge gained by seeing and becoming acquainted with the rich fauna of the bay. Personally speaking, to observe alive so many forms only seen before in drawings, or at most as preserved specimens, has been a source of keen enjoyment. Further, the intercourse with men of other nationalities, and of other ideas and methods, cannot but have a beneficial effect on those who stay for any length of time. For these privileges my sincere thanks are due to the Committee of the British Association. II.

RAVENSTEIN (Chairman), Mr. BALDWIN LATHAM, Mr. G. J. SYMONS, Mr. H. N. DICKSON, and Dr. H. R. MILL (Secretary). (Drawn up by the Chairman.) YOUR Committee in the course of last year granted a complete set of instruments, including a mercurial barometer presented to them by the Meteorological Council, to the Scottish missionaries established at Kibwezi, on the road from Mombasa to Machako's. They also supplied Mr. Hobley, now in Uganda, with one of Symons's earth thermometers. 'Sets of instruments have now been supplied to the following stations: Bolobo (Rev. R. Glennie).-Registers up to date have been regularly received since January 1891. The abstract for the past year has been prepared by Mr. H. N. Dickson. Lauderdale, Nyasaland (Mr. J. W. Moir).—An abstract of one year's observations has been sent home through Mr. Scott Elliott.. Zombe, Nyasaland (Mr. J. Buchanan).-Registers of the observations made from June 1892 to March 1894 have been received. The abstract published in the Appendix has been prepared by Mr. Dickson. Lambarene, Ogowe (Rev. C. Bonzon).-Only one month's observations have been received. Kibwezi, British East Africa (Scottish Mission). The instruments were only granted this year. One year's rainfall observations have been received. Warri, Benin (Capt. Gallwey). -The registers have been received up to the date. An abstract has been prepared by Mr. Dickson. The sets at all these stations, with the exception of Warri, include a mercurial barometer, four thermometers, and a rain-gauge. That at Warri includes a black bulb thermometer. Meteorological reports from thirteen stations in British East Africa have been received. These stations lie on or near the coast, between Wasin and the Jub, and along the road connecting Mombasa with Fort Smith in Kikuyu, the climate of which is described as being exceptionally well suited to European residents. These observations were, in most instances, made by officials of the Imperial British East Africa Company. The abstracts have been prepared by the Chairman. (See Map, p. 491.) Your Committee regret that the instructions laid down for the guidance of observers should, in many instances, have been set aside, and that observations should have been made at hours precluding the possibility of deducing trustworthy means. Where circumstances do not admit of the instruments being read thrice daily at 7 A.M., 2 P.M., and 9 P.M.-the thermometers should be read at 9 A.M., or twice daily, at an interval of twelve hours. The barometers, however, should be read at intervals of six hours say at 9 A.M. and at 3 P.M. Your Committee have expended the 51. granted. They beg to propose that they be reappointed, and that a grant be made of 107., which would enable them to establish a station near Lake Ngami. 1895. Zomba. Lat. 15° 23' S., Long. 35° 20' E., 3,130 feet. The readings of the barometer were reduced to 32° F. by the observer. A further correction for gravity, amounting to -0-068 in., has been applied in accordance with the formu a p=p' (1-0-0026 cos 24) (1-0-0000003/). The pressure of vapour and re'ative humidity have been deduced from the readings of the wet and dry bulbs by means of Guyot's Tables (4th ed., p. 82), with corrections as for mean barometric pressure of 27 0 in.
