Mr. FRANCIS GALTON said that all geographers must congratulate themselves on the accession to their ranks of so able a young traveller as Mr. Johnston, who had the power of graphically describing what be had seen. He wished to ask one or two questions. Captain Tuckey in his return journey described the cataracts as having dwindled down to nothing more than the appearance of a Scotch burn, and stated that at that season of the year the volume of water passed underground, giving a very strange notion of the cavernous character of its stony bed. He wished to know what modern travellers on the Congo had to say about that statement. Another point on which he wished for information was this. In the old days of the slave trade, the men most stunted in growth and most peculiarly negro in appearance were said to come from Ambriz. It was known that a little inland the races were of a very much higher order, and Mr. Johnston had spoken of a perfect man of the world, of high intelligence, and free from superstition, who lived less than 300 miles from Ambriz. He wished to know where the lower race yielded to the higher one, and whether the transition was abrupt or gradual. It would also be highly interesting to himself to learn from Mr. Johnston, who had had the singular opportunity of comparing the races on the higher Congo with those on the Cundnd, what he considered to be their relative capacity and worth.
