At the same time, he was on the faculty of Georgetown, teaching medicine from 1888 to 1902 and histology from 1895 to 1902. From 1907 to 1910 he led the Philippine Expedition aboard the USS Albatross. He was an associate editor of the National Geographic Society from 1909 to 1919. He was the author of many articles and publications, both popular and scientific, about fish. He was deputy commissioner of the U. S.
