He was graduated at the medical department of Harvard University. He became a professor of physiology in the University of Buffalo, and was the first professor in the United States to teach vivisection. As a physiology Dalton supports vivisection and thinks that it is necessary for humans to learn more from vivisection and to improve from it.
