By the Rev. Mr. Steinhauer.—The United Brethren have visited 
this coast as missionaries. They formed a settlement at Nain, in N. 
Jat. 56° 38’; and afterwards two others, Okkak in lat. 58° 43’, and 
Hopeiland in lat. 55° 36’.. It is by these missionaries that all the 
Labrador minerals have been sent to Europe. The present notice 
is drawn up from the information of the missionaries. The coast is 
mountainous and nearly barren, the rocks being bare of soil. Dee 
rifts are common, as if they were veins not yet filled up. The. 
rocks, as far as observed, are primitive; granite and chlorite are 
particularly mentioned; both the Hypersten and the Labrador fel- 
spar seem to occur in primitive rocks. Floetz or transition rocks 
occur at Hopedale ; for lime-stone has been found there containing 
madrepores. The height of the mountains is estimated at 3000 feet. 
XXI. Memoranda relative to Clovelly, North Devon.—By the 
Rev. I. I. Conybeare, M. G. S.—This is a very interesting paper. 
The rocks at Clovelly are grey-wacke and grey-wacke-slate. Several 
distinct drawings are given of the contortions of the beds. Who- 
ever will take the trouble to examine these drawings Will see how 
utterly impossible it is to account for these contortions by the 
squeezing system, which has been brought forward with such 
parade. The view of Mr. Conybeare with respect to the Cornish 
clay-slate is the same which I myself gave in my paper on Corn- 
wall. But there are some circumstances which throw doubts upon 
the real position of the Cornish slate. The slate at Plymouth is 
undoubtedly transition ; yet it possesses all the characters of the 
killas of Cornwall. This transition slate may be traced as far west 
as St. Michael’s Mount; and from the direction of the beds there 
can be no doubt that it passes under the granite, which constitutes 
the greatest part of that mount. Indeed, upon the south-west side 
of the mount it may be found alternating with that granite. Hence 
the mere appearance of the killas is not sufficient to constitute it a 
primitive rock. We have no proof at present to the contrary ; but 
the discovery of any petrifactions in it would bea decisive proof. It 
is to be hoped, therefore, that the Gentlemen in Cornwall who are 
interested in the subject will endeavour to ascertain whether any 
such petrifactions exist in it or not. 
XXII. On Staffa. By Dr. Macculloch.—Staffa has been so 
often described that little remains to be said respecting it. Dr. M. 
visited it twice, and examined it with as much care as possible. 
The columns, he says, are basalt. From the specimens which I 
have examined, I conceive that the term porphyry-slate is more 
applicable to the rock of Staffa than basalt. The Doctor refuses to 
admit the presence of trap tuff in Staffa, though there cannot be a 
doubt that the pillars stand upon trap tuff. Trap tuff is not a 
breccia, as Dr. M. supposes. Nothing is more easy than to study 
this rock, as a considerable part of Arthurseat is composed of it. 
Its base is a retlithelonnian clay. It contains what has the appear- 
ance of fragments of other stones; but a careful examination will 
satisfy any person that they are not real fragments, but minerals,
