whom there had long subsisted an
intimate correspondence, nor did their reciprocally differing in some
opinions, diminish the friendship they mutually manifested for each
other.

The year 1749, furnished two new productions from our author; a
translation of one of which follows these memoirs. The other is
entitled, _a discourse on the scurvy_, affixed to Mr. _Sutton_'s
second edition of his _method for extracting the foul air out of
ships_.

It is more than possible that, but, for the patronage of Dr. _Mead_,
this contrivance, which confers no less honour to the inventor, than
utility to the public, might have been for ever stifled: our author,
than whom no one more ardently wished for, or more zealously promoted
the glory and interest of his country, being thoroughly convinced of
its efficacy, so earnestly, and so effectually recommended it to the
lords of the admiralty, as to prevail over the obstinate opposition
that was made against its being put into practice. To the same purpose
in 1742, he explained the nature and conveniencies of this invention
to the royal society,[23] and with the same view he confessedly wrote
the last mentioned discourse, of which he made a present to Mr.
_Sutton_.

1741-2, and published in Mr. _Sutton_'s account, page 41. He
also presented a model of this invention made in copper to
the royal society, which cost him 200l.

His _medical precepts_ and _cautions_, which appeared in 1751, and was
his last publication, affords an indisputable testimony, that length
of years had not in the least impaired his intellectual faculties.
Our author has herein furnished the public, with the principal helps
against most diseases which he had either learned by long practice, or
deduced from rational principles.[24] Who could with the same
propriety take upon himself to be an instructor and legislator in the
medical world, as he who had been taught to distinguish truth from
falsehood, in the course of so extended an experience, protracted now
to almost threescore years? to this may be added, that he has so
contrived to blend the _utile dulci_, by embellishing his precepts
with all the delicacy of polite expression, as to render them at the
same time not less entertaining than instructive.
