During his connection with the survey work Mr. Hunt took part in the great exhibitions of 1856 and 1867, acting as judge at both, while his services in a similar connection were sought at the Centennial Exposition in Philadelphia in 1876. His fame was world-wide as the result of his investigations and researches were made known, for he took the lead in much pioneer geological work on the North American continent. From 1856 until 1862 Dr. Hunt was professor of chemistry at Laval University in Quebec and was continued as one of its honorary professors until his death. His annual course of instruction there comprised forty lectures in the French language and for some years he was also lecturer at McGill University. In 1872 he accepted the chair of geology in the Massachusetts Institute of Technology in Boston, there remaining until 1878, when he resigned in order to concentrate his efforts upon further study and professional work. His scientific attainments have gained him recognition both on the American and European continents. Harvard University created him Master of Arts in 1852 and from Laval and McGill Universities he received the degree of Doctor of Science. In 1881 he had the unusual honor of receiving the degree of Doctor of Laws from Cambridge University of England, and in special recognition of his eminence as a geologist he was created a fellow of the Royal Society of London in 1859. In 1874 he was elected to membership in the National Academy of Sciences of the United States and in 1882 he was one of those called upon by the Marquis of Lorne to aid in the organization of the New Royal Society of Canada, becoming that year chief of the section of physical and mathematical sciences. In 1884 he was elected its president. Thus year after year honors were conferred upon him--honors well merited yet worn with becoming modesty. He was one of the founders of the American Association for the Advancement of Science at Philadelphia and in 1870 was elected to its presidency. He was also an early member of the American Institute of Mining Engineers and was its president in 1877, while in 1880 he became the founder and president of the American Chemical Society. Among the decorations conferred upon him was that of the Legion of Honor, bestowed by Napoleon III, and the cross of St. Mauritius and St. Lazarus from the king of Italy. He contributed much to scientific literature and was a well known lecturer on scientific subjects. He frequently went abroad for study, spending much time in that way in Great Britain, Switzerland and Italy. A chemical green ink which he invented in 1859 was the cause of giving the name of greenbacks to American currency. His explorations on the American continent had extended from the Gulf of St. Lawrence southward to the Gulf of Mexico and westward to the Pacific.
