ge in 1822, and entering upon his duties
January 1, 1823, opened the Lyceum, was inaugurated as its principal,
and delivered an address on the occasion. He soon after returned his
license, finding it inconvenient to meet the many calls for preaching
extended to him, and having become also so settled in his preference
for the Protestant Episcopal Church that he determined to take Orders
therein, should he ever be so situated as to think it his duty to
preach again. On the 9th day of April, 1823, he was married to Mary
Caroline King, the eldest daughter of the Hon. Cyrus King, M. C.

The Lyceum soon attracted students and became a flourishing
institution. Its principal gave lectures in Chemistry and taught
Mathematics and Natural Philosophy, and in winter had classes in
Architecture and in Agricultural Chemistry. For the former of these
classes he prepared, in 1827, a work on the "Elementary Principles of
Carpentry."

In July, 1827, having received an invitation to succeed Professor Dana
in the chair of Chemistry at Dartmouth College, Mr. Hale accepted, and
delivered his inaugural address on the day after Commencement. His
esteemed and able colleagues in the Medical College were Reuben D.
Mussey, M.D., Prof. of Anatomy and Surgery; and Daniel Oliver, M.D.,
Prof. of Theory and Practice of Medicine. It should be noted that at
that period the importance of physical studies was not fully
appreciated at Dartmouth. The college had not taken a scientific
periodical in half a century. There was no cabinet of minerals.
"There was not," writes Dr. Oliver, "a single modern volume in the
college library upon either Mineralogy or Geology; and scarcely one,
if one, upon Chemistry, later than the days of Fourcroy or Vauquelin.
The prevailing taste was decidedly anti-physical. It was directed
another way, and not only so, but there was among the college Faculty
a disposition to undervalue the physical sciences." Dr. James F. Dana,
the predecessor of Professor Hale, writing of the college in reference
to physical science, used the following remarkable expression: "It was
anchored in the stream, and served only to show its velocity." When
Professor Hale was engaged, his duties comprised a course of daily
lectures to the medical class through the lecture term, to which
lectures the members of the Senior and Junior classes were to be
admitted; and instruction to the Junior class in some chemical
text-book by daily recitations for five or s
