Another hunt for a historical work ended successfully at @BioDivLibrary :)
I visited Japan solely for the purpose of studying the Brachiopoda of the Japanese seas, and this step led to my accepting the chair of zoology in the Imperial University at Tokyo. Gradually I was drawn away from my zoological work, into archaeological investigations, by the alluring problem of the ethnic affinities of the Japanese race. The fascinating character of Japanese art led to a study, first of the prehistoric and early pottery of the Japanese, and then to the collection and study of the fictile art of Japan. Inexorable fate finally entangled me for twenty years in a minute study of Japanese pottery. The results of this work are embodied in the Catalogue of Japanese Pottery, lately published by the Museum of Fine Arts, Boston. With this work off my hands, I turned back with eagerness to my early studies of the Brachiopoda (…) Japan is the home of the brachiopods.Edward S. Morse, 1902.
