APPENDIX.


            BY LARRIOT W. WARNER.




  THE last years of the life of Dr. Caldwell were passed almost
exclusively in the retirement of his study, and the society of his
immediate family. At no time of his life could he have been
considered, in the common acceptation of the term, a social man.
  Although, in society, his success had been eminent, and his
colloquial powers were equalled by very few; yet the general
tone of his mind, his pursuits, and the ends he labored for, united
in rendering him alike unwilling and unfit for promiscuous asso-
ciation. Life to him, from his boyhood to his octogenarian age,
was always a serious business. If he labored to attain distinction
for himself, his efforts tended as earnestly and successfully to
benefit others. His whole career was composed of a series of
earnest, persevering, honest endeavors to discover, promote, and
diffuse truth. In defence of what he believed to be useful truths,
whether natural, scientific, or philosophical; he was prepared, at
all times, and under all circumstances, to do, and dare, and suffer.
And his courage was as dauntless as his powers were great; what-
ever his success, his aim has always been high, noble, and true.
  If, in the latter years of his life, his circle of intimate personal
friends were few, their attachment to him was proportionably
strong. Time had removed from him many of his early and tried
friends, and estringement had separated others from his decline.
But by the few who remained to him, and knew him well, he was
held in the tenderest regard, and is remembered with unfading
reverence.
