Since the establishment of the free lectures, over five thousand have been given to the people by some of the most eminent and learned men of both hemispheres,--Lyell, Tyndall, Wallace, Holmes, Lowell, Bryce, and more than three hundred others. Sir Charles Lyell lectured on Geology, Professor Asa Gray on Botany, Oliver Wendell Holmes on English Poetry of the Nineteenth Century, E. H. Davis on Mounds and Earthworks of the Mississippi Valley, Lieutenant M. F. Maury on Winds and Currents of the Sea, Mark Hopkins (President of Williams College) on Moral Philosophy, Charles Eliot Norton on The Thirteenth Century, Henry Barnard on National Education, Samuel Eliot on Evidences of Christianity, Burt G. Wilder on The Silk Spider of South Carolina, W. D. Howells on Italian Poets of our Century, Professor John Tyndall on Light and Heat, Dr. Isaac I. Hayes on Arctic Discoveries, Richard A. Proctor on Astronomy, General Francis A. Walker on Money, Hon. Carroll D. Wright on The Labor Question, H. H. Boyesen on The Icelandic Saga Literature, the Rev. J. G. Wood on Structure of Animal Life, the Rev. H. R. Haweis on Music and Morals, Alfred Russell Wallace on Darwinism and Some of Its Applications, the Rev. G. Frederick Wright on The Ice Age in North America, Professor James Geikie on Europe During and after the Ice Age, John Fiske on The Discovery and Colonization of America, Professor Henry Drummond on The Evolution of Man, President Eliot of Harvard College on Recent Educational Changes and Tendencies. Professor Tyndall, after his Lowell lectures, gave the ten thousand dollars which he had received for his labors in America in scholarships to the University of Pennsylvania, Harvard University, and Columbia College. Mr. John Amory Lowell, a cousin of John Lowell, Jr., and the trustee appointed by him, at the suggestion of Lyell, a mutual friend, invited Louis Agassiz to come to Boston, and give a course of lectures before the Institute in 1846. He came; and the visit resulted in the building, by Mr. Abbott Lawrence, of the Lawrence Scientific School in connection with Harvard College, and the retaining of the brilliant and noble Agassiz in this country as a professor of zoölogy and geology. The influence of such lectures upon the intellectual growth and moral welfare of a city can scarcely be estimated. It is felt through the State, and eventually through the nation.
