ion, so generally
and so truly amiable as the naturalists. The contemplation of nature
seldom fails to produce an elevation of character; it also begets a
sweetness of disposition flowing from a sense of what is beautiful in
creation; and the evidences of beneficence, everywhere so abundant,
soften the feelings and impart to the individual a sincere benevolence
of heart. This disposition was strikingly manifested in Jenner, to whose
affection, kindness, meekness, good-will, and benevolence so many have
borne the most ample testimony. It was no uncommon thing for Jenner to
be accompanied in his daily professional tour of many miles by friends,
who have eagerly listened to the outpourings of his mind called forth by
the beauties which in the vale of Gloucester surrounded him.

His observations on the structure and economy of the various objects of
natural history were delivered with the most captivating simplicity and
ingenuity. Full of information himself, he delighted to impart it, and
was equally solicitous of obtaining a return from others. He was an
enthusiast in his devotion to nature, and he anxiously desired that all
should participate in the gratification which such a study never failed
to afford. He united in an especial manner a talent for the most
profound observations to a disposition most lively and ardent
distinguished by mirth, playfulness, and wit. With these powers, it is
not surprising that his society should have been much courted; and,
fully engaged as he was by the duties of an extensive practice, he yet
found time to cultivate an acquaintance with polite literature. Many
little productions of his muse have appeared in print; they were
addressed to some of his more favored correspondents, or occasionally
read at convivial meetings, and display the turn of his mind, the
benevolence of his disposition, and the liveliness of his imagination.
His best poetical productions find their subjects in natural history.
_The Signs of Rain_ unites the accuracy of the naturalist with the fancy
of the poet.

Jenner had nearly passed half a century before he made known to the
world his experiments and investigations relative to the vaccine
disease. His first successful vaccination was made May 14, 1769. His
ardor from an early period had been noticed, and it took its rise from
the following accidental circumstance. While a pupil with Mr. Ludlow, a
young countrywoman applied for advice. The subject of smallpox was
