II. XI. Observation on the Hill of Kinnoul, in Perthshire.
By the J. Mac Culloch, M.D. F.L.S. president of the geological society, Chemist to the Ordnance, Lecturer on Chemistry at the Royal Military Academy, and Geologist to the Trigonometrical Survey
IN transmitting to the Society the specimens from the hill of
Kinnoul which accompany this paper, I have thought it necessary
to enter into a description somewhat detailed, of appearances attended
with considerable interest, and involving some difficulties.
We are yet, it is to be feared, in want of a theory capable of solving
all the cases which the increased activity of geological research
is daily bringing to light. It is among difficult and unexplained
phenomena that we are to seek for the stimulus which will lead us
to pursue those researches on the multiplication of which alone we
can hope to found a true system; and it is to a salutary distrust
of the all-sufficiency of any hypothesis, that we must look for protection
from its paralyzing effects.
The hill of Kinnoul, from which the specimens now before the Society were selected, has been frequently visited by geologists and mineralogists, more perhaps with a view to the minerals which the rock contains than for the purpose of examining those remarkable geological phenomena which it exhibits. Except the account of it in the travels of Faujas de St. Fond, I know not that any description of this hill has been laid before the public. The peculiar opinions
