Not illustrated. 1868 edition. Excerpt: ...some places more than two miles in breadth, similar to the stream from Etna in 1669, five caldron-like craters lie in a row upon the ridge of Hecla. As the principal fissure is directed N. 65 E., the volcano, when seen from Selsundsfjall, that is from the southwest side, and therefore in transverse section, appears as a pointed conical mountain. f Kleinere Schnften, bd.

J See Adolf Evman's Reise um die Erde, which is also very important in a geognostic point of view, bd. iii., s. 271 and 207. If the forms of volcanoes are so remarkably different (Cotopaxi and Pichincha) without any variation in the matters thrown out, and in the chemical processes taking place in the depths of their interior, the relative position of the cones of elevation is sometimes still more singular. Upon the island of Luzon, in the group of the Philippines, the still active volcano of Taal, the most destructive eruption of which was that of the year 1754, rises in the midst of a large lake inhabited by crocodiles (called the Laguna de Bombori). The cone, which was ascended in Kotzebue's.voyage of discovery, has a crater-lake, from which again a cone of eruption, with a second crater, rises. t This description reminds one involuntarily of Hanno's journal of his voyage, in which an island is referred to, inclosing a small lake, from the centre of which a second island rises. The phenomenon is said to occur twice, once in the Gulf of the Sartorins von Waltershausen, Physisch-geograpKsche Skieze von Island, 1847, s. 107; and his Geognostischer Atlas von Island, 1853, Tafel xv. and xvi. t Otto von Kotzebue, Entdecknngs-Reise in die Siidsee und in die Berings-Strasse, 1815-1818, bd. iii., s....
