[2] H. B. Guppy (_R. S. G. Soc. Magazine_, 1889) holds that there is no sufficient proof of this connexion but gives interesting details of the present movement. [3] See G. F. Tijdeman's map of the depths of the sea in the eastern part of the Indian archipelago in M. Weber's _Siboga Expedition_, 1903. The details of the coast forms of the island have been studied by J. F. Snelleman and J. F. Niermeyer in a paper in the Veth _Feestbundel_, utilizing _inter alia_ Guppy's observations. [4] This Merapi must be carefully distinguished from Merapi the Fire Mountain of Sumatra. [5] R. D. M. Verbeek and R. Fennema, _Description géologique de Java et Madoura_ (2 vols. and atlas, Amsterdam, 1896; also published in Dutch)--a summary with map was published by Verbeek in _Peterm. Mitt._ xliv. (1898), 24-33, pl. 3. Also K. Martin, _Die Eintheilung der versteinerungsführenden Sedimente von Java_, Samml. Geol. Reichsmus. Leiden, ser. i., vol. vi. (1899-1902), 135-245. [6] On the 16th of November the sun rises at 5.32 and sets at 5.57; on the 16th of July it rises at 6.12 and sets at 5.57. The longest day is in December and the shortest in June, while on the other hand the sun is highest in February and October and lowest in June and December. [7] S.

Weber, _Siboga Expedition_. [10] The _Annales de Buitenzorg_, with their _Icones bogorienses_, are universally known; the _Teysmannia_ is named after a former director. A history of the gardens was published by Dr Treub, _Festboek van's Lands Plantentuin_ (1891). [11] Bertha Hoola van Nooten published _Fleurs, fruits et feuillages de la flore et de la pomone de l'île de Java_ in 1863, but the book is difficult of access. Excellent views of characteristic aspects of the vegetation will be found in Karsten and Schenck, _Vegetationsbilder_ (1903). [12] It is interesting to compare this with the natural "reflorization" of Krakatoa. See Penzig, _Ann. jard. de Buitenzorg_, vol. viii. (1902); and W. Botting in _Nature_ (1903). [13] See Walbreken, _De Taalsvorten in het Javaansh_; and G. A. Wilken, _Handboek voor de vergelijkende Volkenkunde van Nederlandsch Indie_, edited by C. M. Pleyte (1893). [14] See Van den Berg's account of the MSS. of the Batavian Society (the Hague, 1877); and a series of papers by C. Poensen in _Meded. van wege het Ned. Zendelinggenootschap_ (1880).
