these words, which I beg leave to quote: ‘* From Callendar we set 
out to visit the famed and interesting scenery of the pass of Leney, 
by which the traveller on this route enters the Grampian range. 
About two miles beyond Callendar we found the rock through 
which the road is cut to be very distinct greywacke, and traced it 
till we found it about half a mile further on towards the north-west, 
very near the mica-slate ; but could not see the junction of these 
two rocks, or whether the clay-slate intervened between them. 
We were both perfectly satisfied that in this district the transition 
rocks, greywacke, and greywacke-slate, come in between the floetz 
and the primitive country.” And again in the same paper (p. 29), 
« In the evening of the 16th we visited the fall at Bracklin bridge, 
about a mile to the east of Callendar. The rock is conglomerate, 
and broken down by the action of the water into many fine and 
fantastic forms. We had the conglomerate all the way from Cal- 
lendar to this fall; and on tracing the river about two miles up, 
observed no other rock; but Mr. lardine told me that some time 
ago Sir James Hall found greywacke about a mile or two higher 
up than we were. Night prevented our reaching it.” 
“ The greywacke and greywacke-slate appear about two miles 
after leaving Callendar, on the road to Loch Catherine. They 
continue all along the valley of Loch Venachar and Loch Achray to 
the Trossacks, and the eastern part of these hills is composed of 
greywacke.

XI. Intended Publication on Greenland. 
Mr. Wm. Scoresby, jun. has in the press a work which he pro- 
poses to call the History of East and West Greenland, and of the 
Northern Whale Fisheries. 
The author of this work, having been in the habit of annually 
visiting the Greenland seas, since the year 1802, began about 10 
years ago, for his own amusement, to make memoranda of the 
various natural phenomena with which this country abounds. 
Finding his notes rapidly increase, both in interest and variety, as 
well as in bulk, and observing that they contained a collection of 
facts, which must be in a great measure unknown to the world in 
general ; considering, at the same time, the singular barrenness of 
information on subjects of such general interest and national im- 
ortance as the History of the Greenlands, and of the Northern 
hale Fisheries, he was induced to undertake the work, a pro- 
spectus of which is now respectfully submitted to the public. 
It is well known, that no book in the English language has yet 
been devoted to the same objects with the work now announced, 
since the time of Egede and Crantz; and these authors merely 
mention the whale fisheries in a cursory manner, and neglect alto- 
gether their establishment and history. ‘The French and Dutch, 
meanwhile; have each issued different works expressly on the sub-
