August - November 1875,

Heinke Jäger, Editor


Heinke Jäger compiled the following notes from Theodor Wolf's Ein Besuch der Galápagos-Inseln, Sammlung von Vortraegen fuer das deutsche Volk (“A Visit to the Galápagos Islands: A Collection of Presentations for the German People”) in Biol. Centralblatt, 1892, vol. 12, pp. 221-250. Wolf refers to José de Valdizán here as “Baldisan.”

Additional feral animal notes added (in sans-serif font) based on notes from Barbara West, from information extracted from Georg Baur's “On the Origin of the Galápagos Islands” in The American Naturalist, April 1891, vol 25, pp. 307-326. Baur paraphrases Teodoro Wolf's Apuntes sobre el clima de las Islas Galápagos, segun los observaciones hechas durante un viaje en los Meses de Agosto a Noviembre de 1875. (“Notes on the Climate of the Galápagos Islands, from Observations made during a Voyage in the Months of August-November, 1875.”) in Bol. Observ Astronomico, 1879, Quito (further details unknown). Modern island names are given here.—JW.
