pter was gathered for a paper
read before the Medical Improvement Society of Boston in the spring of
1911. In nearly its present form it was published in _The Popular
Science Monthly_ for May, 1911, and thanks are returned to the editor of
that magazine for permission to reprint it here. The additions that have
been made refer particularly to the estimation of Aristotle in the
Middle Ages.]
