The tutor's chair at Dartmouth has been filled by many men of high promise, some going to premature graves, others to what they deemed more inviting fields. Among them we find such names as Calvin Crane, Moses Fiske, Asa McFarland, John Noyes, the value of whose instruction was gratefully acknowledged by Dartmouth's most illustrious son a quarter of a century after his graduation, Thomas A. Merrill, Frederick Hall, Josiah Noyes, Andrew Mack, John Brown, Henry Bond, William White, Rufus W. Bailey, James Marsh, Nathan Welby Fiske, Rufus Choate, Oramel S. Hinckley, John D. Willard, Henry Wood, Ebenezer C. Tracy, Ira Perley, Silas Aiken, Evarts Worcester, Jarvis Gregg, and Samuel H. Taylor. We cannot dwell upon individual merit, nor give even the names of all who have rendered valuable service in this sphere. The "Indian Charity School," also has had many teachers of distinguished worth. Among them we find such names as Benjamin Trumbull, the historian, to whom we have referred heretofore; Ralph Wheelock, the favorite son of the honored founder, who would doubtless have left to him his official mantle, but for the early failure of his health; James Dean, whose name is indelibly engraven upon the earlier periods of our national history, Jacob Fowler, who well illustrated the value of Christian civilization to the Indian; Caleb Bingham and Elisha Ticknor, whose names are closely interwoven with the educational history of New England's metropolis, Josiah Dunham, Judah Dana, Caleb Butler, William A. Hayes, the intimate and honored friend of Francis Brown, Joseph Perry, John S. Emerson, and Osgood Johnson. CHAPTER XXVII. MEDICAL DEPARTMENT.--PROFESSORS NATHAN SMITH, REUBEN D.
