, 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
believed to have helped in the compilation of Mr. G.G. Mill's
"Catalogue of the Plants of Great Marlow, Bucks."

The mere recording of isolated facts of this kind of course affords no
scope for any style in composition. It may, however, be thought worth
while to reproduce here the concluding paragraph of a short article on
"Spring Flowers in the South of Europe," as a sample of Mr. Mill's
popular manner, as well as for its own sake as a fine description of a
matchless scene. He is describing the little mountain range of Albano,
beloved of painters, and, after comparing its vernal flora with that
in England, goes on:--

'If we would ascend the highest member of the mountain group,
the Monte Cavo, we must make the circuit of the north flank
of the mountains of Marino, on the edge of the Albano Lake,
and Rocca di Tassa, a picturesque village in the hollow
mountain side, from which we climb through woods, abounding
in _Galanthus nivalis_ and _Corydalis cava_, to that summit
which was the _arx_ of Jupiter Latialis, and to which the
thirty Latian cities ascended in solemn procession to offer
their annual sacrifice. The place is now occupied by a
convent, under the wall of which I gathered _Orinthogalum
nutans_; and from its neighborhood I enjoyed a panoramic
view, surely the most glorious, in its combination of
natural beauty and grandeur of historical recollections, to
be found anywhere on earth. The eye ranged from Terracina on
one side to Veii on the other, and beyond Veii to the hills
of Sut
