The first detailed geographical and geological description of central Kalimantan, now part of Indonesia, written by the Dutch geologist Gustaaf Adolf Frederik Molengraaff (1860-1942). Profusely illustrated with fine photographed plates, maps and a comprehensive geological description of the region. In the rear is the English appendix containing the work of G. J. Hinde, " Description of fossil Radiolaria from the rocks of central Borneo, obtained by Prof. Dr. G. A. F. Molengraaff in the Dutch Exploring Expedition of 1893-94". The main work has 52 plates, the 56 pp. appendix by Hinde has four. A separately published atlas is not included. This is the copy of the German-born Dutch geologist Johann Karl Ludwig Martin (1852-1941), who received this copy from Molengraaf himself, as can be seen on the front free endpaper which has Martin's tiny printed label, and Molengraaff's handwriting, dated 4.III.1901. Fig. 89, a correction to map one, tipped in between pp. 418-419; printed correction to the index on p. 520 pasted in; a few light pencil markings, short split in the rear hinge. Otherwise a very good, clean copy. Cat. BM(NH) p. 1333.
