botany; surely in all ways one very well suited to him.

Of the tens of thousands who are acquainted with the philosophical
writings of Mr. Mill, there are probably few beyond the circle of his
personal friends who are aware that he was also an author in a modest
way on botanical subjects, and a keen searcher after wild plants. His
short communications on botany were chiefly if not entirely published
in a monthly magazine called "The Phytologist," edited, from its
commencement in 1841, by the late George Luxford, till his death, in
1854, and afterwards conducted by Mr. A. Irvine of Chelsea, an
intimate friend of Mr. Mill's, till its discontinuance in 1863. In the
early numbers of this periodical especially will be found frequent
notes and short papers on the facts of plant distribution brought to
light by Mr. Mill during his botanical rambles. His excursions were
chiefly in the county of Surrey, and especially in the neighborhood of
Guildford and the beautiful vale of the Sittingbourne, where he had
the satisfaction of being the first to notice several plants of
interest, as _Polygonum dumetorum_, _Isatis tinctoria_, and _Impatiens
fulva_, an American species of balsam, affording a very remarkable
example of complete naturalization in the Wey and other streams
connected with the lower course of the Thames. Mr. Mill says he first
observed this interloper in 1822 at Albury, a date which probably
marks about the commencement of his botanical investigations, if not
that of the first notice of the plant in this country. Mr. Mill's
copious MS lists of observations in Surrey were subsequently forwarded
to the late Mr. Salmon of Godalming, and have been since published
with the large collection of facts made by that botanist in the "Flora
of Surrey," printed under the auspices of the Holmesdale (Reigate)
Natural History Club. Mr. Mill also contributed to the same
scientific magazine some short notes on Hampshire botany, and is
