it would be worse than useless, for more than likely it would be incorrect.
Note 1.—Mr. E. J. Dunn, an accomplished geologist, during many years of search in South Africa made a very large collection of stone implements, which he was good enough to allow me to inspect on several occasions. I was unable to detect any difference between the most ancient of these implements and the magnificent exhibits of chipped stones which I saw afterwards in the museums of London and Brussels, but of course I was unable to compare them side by side. Mr. Dunn was convinced that they were all of Bushman manufacture, and that some of them had lain undisturbed since the beginning, or nearly the beginning, of the present geological period, but he had found none in the later tertiary deposits. Most of the tiny perforated stones found by him were irregular in shape, and he could not ascertain to what use they had been put, though an old Bushwoman showed him how they were drilled, as well as how to attach a stone head to an arrow. A very interesting paper on The Stone Implements of South Africa, by Mr. Dunn, is to be found in the Transactions of the Philosophical Society during 1880.
Note 2.—Two short papers entitled Stone Implements in South Africa, with a sheet of illustrations, by Sir Langham Dale, Superintendent General of Education in the Cape Colony, were published in the Cape Monthly Magazine of October and December 1870.
Note 3.—A short paper entitled Notes in connection with Stone Implements from Natal, by John Sanderson, Esqre., of Durban, Natal, is to be found in the Journal of the Anthropological Institute for August 1878.
Note 4.—A lengthy paper on The Stone Age of South Africa was read by W. G. Gooch, Esqre., C.E., M.A.I., before the Anthropological Institute on the 11th of January 1881, and is published in Volume XI of the Journal. It is illustrated with numerous plates.
Note 5.—A very interesting volume on The Stone Implements of South Africa, with 258 illustrations, by J. P. Johnson, crown quarto, fifty-three pages, was published in London in 1907.
Note 6.—In a very interesting diary of a Tour through Bushmanland by the geologist Mr. E. J. Dunn, published in the Cape Monthly Magazine in December 1872, the following paragraph occurs: “July 11th.—Processfontein.—Let us examine the river bank close by. On the top, thickly sprinkled through the loose red sand, are black stone implements. They continue through the underlying clay, through a layer of hard carbonate of lime and sand, through a soft calcareous bed, and below this mixed with gravel formed from shale and resting on the bottom of shale and trap; that is to say, through a total depth of from nine to twelve feet of stratified
