British Science Meeting to Travel in South Africa. The 1929 Meeting of the British Association for the Advancement of Science will be a somewhat unique combination of a scientific assemhly and a scientific tour, in that i t will be held in two widely separated cities, Capetown and Johannesburg, and the two-day railway journey northward will come as a break in the middle of the Dromam. . . The visiting scientists from Britain and other countries of the northern hemisphere will land in Capetown on themorning of July 22nd, and themeetings there will begin on the same day. Then, on July 28th and 29th. sections of the Association will start for Johannesburg by rail, a m n n g there on July 30th and31st. At Johannesburg the meetings will continue until August 3rd. I n addition to the long but interesting train journey between the two meeting places, there will he a number of systematic tours t o points of scientific and scenic interest, including the famous gold fields and diamond mines. A third citv, Pretoria, will participate in the scientific activities of the season. The Fifteenth International Geological Congress is to be held there from July 29th to August 7th. The Pan-African Agricultural and Veterinary Congress will also meet in Pretoria. Since this city is only about an hour's run from Johannesburg, delegates to the British Association meeting will have no difficulty in attending such sessions as they wish to visit a t Pretoria. The British Association for the Advancement of Science has held one previous meeting in South Africa. This took place in 1905.-Science Senn'ce
