decided opinion in this matter, wishing rather to draw atten- 
tion to the facts which seem to be correct, and the more so 
as these were carefully noted on the spot by Mr Whittem 
himself. 
Note.—Near Warwick, and the distriet which lies to the north and north- 
west, there are at least three pleistocene deposits of different age,— 
1. Flints interspersed with numerous small rounded pebbles of ancient and 
other rocks belonging to the glacial period. 
2. The great northern drift, generally and widely distributed over a con- 
siderable area. 
3. Certain gravel-beds near Warwick, and along the valley of the Avon, 
containing occasionally mammalian remains. 
The Flora of Iceland. By W. Lauper Linpsay, M.D., 
F.R.S.E., F.L.S., F.R.G.S., &c. 
A visit to Iceland in June 1860 gave me an opportunity of 
becoming acquainted with some of the general features of its 
Flora; and a residence of eight days in Reykjavik, its capi- 
tal, further enabled me to collect details as to its vegetation 
from its principal naturalists, as well as to study the litera- 
ture of the Icelandic Flora in the archives of the National 
Library. Since my return, I have availed myself of the pub- 
lic libraries of Edinburgh, &c. ; of correspondence with various 
British botanists, whose names will hereafter appear ; and of 
catalogues of foreign works on botany, with a view to discover 
all the floras of Iceland, or works of any kind containing 
lists of its plants, hitherto published. My inquiries at home 
have not enabled me to add many to the works, which, I ascer- 
tained in Reykjavik, contain lists of Icelandic plants. An 
enumeration of all the works—both British and foreign— 
bearing on the Icelandic Flora, so far as Iam aware, hitherto. 
published, and some only of which have been accessible to me, 
will be found in a bibliographical appendix to this paper. The 
general result of my investigations is, that our present know- 
ledge of the plants of Iceland is not so satisfactory as is de- 
sirable, and as the number of lists of such plants would lead 
one at first to infer; that there is no full list, accurate as to 
names and number, up to the present day; and that it is im- 
possible, short of re-collecting and re-naming from fresh speci-
