He was also induced, in 1840, after declining professorships both in
St. Mary's College, Baltimore, and in Pennsylvania University, to
deliver a course of lectures on Materia Medica at the Medical College
of Ohio, but he resigned the chair at the close of the session, and
returned again to Cambridge, where he resided to the close of his
life. Although in declining health at this time, he did not relinquish
professional practice until within a few months of his death, which
took place on the 1st of June, 1842.

bald peaks and angles of this cold region, entitle him to a rank among
metaphysicians as eminent as he maintained in his appropriate
profession."

"The intellectual character of Dr. Oliver," the same writer afterwards
adds, in language admirably chosen, "came nearer than it has been my
fortune to observe in almost any other instance to the idea of a
perfect scholar. He was at once profound, comprehensive, and elegant.
Upon no subject which he had considered was his knowledge fragmentary
or partial. A philosophic, systematic habit of mind led him always to
seek for the principles of things, and to be satisfied only with the
truth. The compass of his inquiries was as extraordinary as their
depth. He had investigated with care a surprising extent of knowledge.
A master of his own language, and minutely acquainted with all its
principal productions, he was also t
