Gentleman's Magazine 1791 p.806
Mr. Isaac Thompson, an eminent land-surveyor, resident at
Newcastle-upon-Tyne, may be reckoned his steadiest patron,
and warmest encourager; for he frequently accompanied this
gentleman, when travailing in the line of his profession,
under the character of an assistant,- an employment that
left him at full liberty to examine the vegetable
productions of the different places visited by them. But it
is difficult to determine, at present, what experience he
gained from his connexion with Mr. Thompson; and the author
of the present essay has scarcely any other means of
discovering what were his opportunities of attending to the
places of growth of the rarer plants, besides his own work
the Synopsis, where the observations are in a great measure
confined to Westmoreland and Northumberland. Perhaps this
was done to accommodate his friends, who were numerous in
those counties, and for whose use the book was chiefly
intended: however, it appears from the volume itself, that
he was not entirely unacquainted with the South of England.
This work was published in the year 1744; it comprehends
that part of Ray's method that treats of the more perfect
herbs, beginning at the fourth genus, or class, and
ending with the twenty-sixth. He promises, in the preface,
to compleat the performance at a future period, provided his
first attempt should meet with a favourable reception from
the publick; but did not live to fulfil his promise, being
prevented by indisposition from finishing a second volume,
which was intended to contain the Fungi, Mosses, Grasses,
and Trees.
He died July 15, 1751, after lingering through the last
three or four years of life in a state of debility that
rendered him unfit for any undertaking of the kind. Some
papers left by him on the subject passed into the hands of
Mr. Slack, printer at Newcastle-upon-Tyne, but were never
published. Among these were some drawings, but it is not
certain whether they were representations of rare plants, or
figures intended to illustrate the technical part of the
science. The writings of Linnaeus became popular in England
a short time after his death, and very soon supplanted all
preceding systems; otherwise the character of Wilson had
been better known to his countrymen at present. His Synopsis
is certainly an improvement on that of Ray; for, besides
some correction in the arrangement, many trivial
observations are left out of it, to make room for generic
and specific descriptions, the most essential parts of a
botanical manual.- He did not increase the catalogue of
British plants much, only adding two to Ray's number, as
distinct species, the Allium schoenopprasum, and the
Valeriana rubra; but he was the first who introduced
the Circea alpina to the notice of the English
botanist, as a variety of Chutitiana, growing near
Sedberg, in Yorkshire.
