Dr. G. Dickie on the Altitudinal Range of Mosses. 299 
are those of Oulough, formed of enormous blocks of rock promis- 
cuously wedged and resting upon each other, frequently forming 
caves and pits, the retreat of numerous foxes, and which are 
sereened by the rather gigantic vegetation of Osmunda regalis, 
Ulex europeus and Calluna vulgaris. The broad surfaces of the 
rocks are beautifully pictured with a map-like coating of Lecidee 
and Lecanore, and on those rocks within a limited circuit and at 
the distance of about fifty yards from the water, the Geomalact, 
on a misty or showery day, may be noticed quiescently stretched, 
their richly maculated character being strikingly conspicuous. 
On what they feed I know not; I never could detect them in an 
eating mood; but I found several amid Oscillatoria Friesii and 
Hypnum proliferum, which abound in masses at the shaded. bases 
of those moist rocks. At the opposite and west side is the ro- 
mantic little Glen of Limnavar, its huge cliffs shaded with a lux- 
uriant indigenous growth of oak (Quercus sessiliflora), Pyrus Au- 
cuparia, Populus tremula, Betula alba and Ilex aquifolium; and. 
on similar rocks, at the same range from the water, 1 again met 
with the Geomalaci, particularly the white variety, but more spa- 
ringly than at Oulough. On no other rocks around the lake or 
- “the country are they to be observed.” 
XXXVITI.—WNotes on the Altitudinal Range of the Mosses in 
Aberdeenshire. By G. Dicxtn, M.D., Lecturer on Botany in 
the University and King’s College of Aberdeen*. 
Some time ago an excursion was made into the interior of Aber- 
deenshire, with the view chiefly of obtaining data for remarks on 
the altitudinal range of the flowering plants growing in that 
county. During this journey notes were taken of the range of 
such Mosses as happened at the time to attract notice. The 
more prominent results in connexion with flowering plants were 
published in the ‘ London Journal of Botany’ ; those having re- 
ference to the Mosses were retained, in the expectation of being 
able to repeat the observations and measurements made with the 
mountain sympiesometer, and of adding to the data ascertained. 
at that time. Such an opportunity not having occurred, these 
remarks have been put together, incomplete although they be, 
principally with the view of directing attention to this yery in- 
teresting subject. A few statements are added on the general 
distribution of the Mosses in Britain, founded chiefly on eata- 
logues of species from several localities, which were sent me by 
Mr. Ralfs. These lists have reference to the following places :
