phia to avail himself of the
advantages of that seat of medical learning, returning to Salem in the
spring of 1818.

In the following year he was induced to undertake, in connection with
the Hon. John Pickering, the preparation of a Greek lexicon, a work
involving much labor and research, and the larger portion of which
fell to his lot. Although mainly based on the Latin of Schrevelius,
many of the interpretations were new, and there were added more than
two thousand new articles. The magnitude of the task and its
successful accomplishment at once raised him to a conspicuous rank
among the scholars of his day.

In the summer of 1820 he accepted an appointment to the professorship
of the Theory and Practice of Medicine, and of Materia Medica and
Therapeutics in Dartmouth College, where he delivered his first course
of lectures in the following autumn. He was also made Professor of
Botany, and his lectures upon Physiology were among his most valuable
contributions to medical literature. He took up his permanent
residence in Hanover, in August, 1821, and from this time to the close
of his connection with the college he was most faithful to all its
interests. In 1825 he was appointed to the chair of Intellectual
Philosophy in the Academical department of the college, a position
which he filled with the ability that distinguished him elsewhere. The
address delivered by him on the occasion of his induction into this
professorship, upon the "Comparative Importance of the Study of Mental
Science," was thus far, perhaps, his most successful literary effort.
Clear, comprehensive, and abounding in passages of remarkable beauty
and force, it established the reputation of its author both as a
writer and a metaphysician.

In 1835 was published his "First Lines in Physiology," a treatise
which received the highest commendation both at home and abroad. It
passed through three editions, and although the rapid advance in
physiological science since its publication has long since led to its
disuse, it will still be admired by medical scholars for the purity of
its style and the learning it everywhere displays.

In the spring of 1837, Dr. Oliver closed his connection with the
college, and returned to Cambridge, where he was temporarily residing
at the time of his appointment, again to resume the practice of his
profession. He, however, delivered a course of lectures at the
Dartmouth Medical School in the autumn of this and the followi
