Owen has published instructive anatomical treatises on the gorilla and the chimpanzee, in addition to those already cited. This English professor had the opportunity of dissecting a young male gorilla, imperfectly preserved in spirits of wine (28). The travellers Burton (29), de Compiègne (30), Savongnan de Brazza (31), Lenz (32), the members of the German-African Loango Expedition (33), and Von Koppenfels (34) have also contributed some information respecting the gorilla in a wild state. Other works on the zoology and anatomy of this animal have been published by Duvernoy, already cited, Dahlbom (35), Haeckel (36), Flower (37), Issel (38), Giglioli (39), Chapman (40), Mivart (41), Macalister (41A), Von Aeby (42), Lucae (43), Ecker (44), Bolau (45), Pansch (46), Lenz (47), A. B. Meyer (48), R. Meyer (49), Bischoff (50), Ehlers (51), Virchow (52), Von Bär (53), by the author of this work (54), etc. Duvernoy, Chapman, Bischoff, Bolau, Ehlers, and I have, like Owen, been able to dissect perfect specimens of the gorilla. Two of the specimens which came into my hands were unquestionably in the best condition, since I obtained them immediately after their deaths in Berlin. A larger specimen of a female, 1000 mm. tall, was in worse preservation, yet still quite available for the purposes of study. The list of anatomical treatises on the gorilla is not yet exhausted. Valuable information may be found in the anthropological works by C. Vogt (55), in the writings of Pruner-Bey (56), and Magitot (57), in Darwin’s works (58), in _Histoire Naturelle des Mammifères_, by Gervais (59), in Huxley’s _Anatomy of Vertebrated Animals_ (60), in Flower’s _Osteology of the Mammalia_ (61), in Giebel’s _Odontographie_ (62), and in many other handbooks and treatises on natural history, which want of room forbids me to mention. In 1860, so far as I am aware, the first living gorilla reached England. It survived its arrival seven months, and a good illustration of this creature, accompanied by a brief description, has been recently published in the _Proceedings of the Zoological Society of London_ (63). In 1876, towards the end of June, Dr. Falckenstein brought the second living gorilla from Loango to Berlin. It had been kept in confinement in that country at the German station Chinchoxo since 1874, and it died on November 13, 1877, at the Berlin Aquarium. Dr. Hermes obtained a third specimen in September, 1881, which died soon after its arrival in Berlin. In 1883 a fourth still survived in the Berlin Aquarium.
