In the same year Silas H. Douglas, M.D., who studied at the University of Vermont, was appointed assistant to Dr. Douglass Houghton, Professor of Chemistry, Mineralogy, and Zooelogy, who never took up the active duties of his chair. Dr. Douglas speedily became one of the "strong men" of the Faculty and created the Chemical Laboratory which lent so much prestige to Michigan in its early years. He was of a systematic and orderly temperament whose experiments before the class always came out brilliantly. His careful business-like methods were greatly appreciated by the Regents and he was entrusted with the oversight of the construction of the South College when it was erected in 1849. So successful was he that he saved some $4,000 over the cost of the first building and had enough bricks left besides to build a large part of the Medical Building which was completed in the same year. Those who knew him best supported him loyally in the great dispute which arose over his administration of the affairs of the Chemical Laboratory and their confidence in his uprightness and sterling integrity was justified by the final decision in that most unfortunate case. These were the men who taught the first class that was graduated from the University in 1845. The same year saw two additions to the Faculty, the Rev. Daniel D. Whedon, Hamilton, '28, who was elected to the chair of Logic, Rhetoric, and History, and Dr. John H. Agnew, Dickinson College, '23, who assumed the Professorship in the classics left vacant by the death of Dr. Whiting. Both had a prominent share in University affairs for a few years. Professor Whedon was a Methodist clergyman, lank and angular in form and feature with a "considerable sprinkling of vinegar at times in his ways of expressing himself," but, according to our oldest living graduate, "his commanding presence, imperative logic and _sesquipedalia verba_, always used with mathematical precision, hammered truth into us and clinched it." Professor Agnew has been described as a Greek from head to foot, the exact opposite of Dr. Whedon, extremely careful in his dress and appearance and correspondingly neat and precise in the expression of his thoughts. He represented the Presbyterian and Congregational element in the University. The reasons for the resignation of these two Professors in 1852 have already been suggested in the lack of unity and the sectarian rivalries of their time.
