“In the coal of Jameson’s Land, on the east side of Greenland, lying
in latitude 71°, and in that of Melville Island, in latitude 75° N.,
Professor Jameson found plants resembling fossils of the coal-fields of
Britain.”[172]
PERMIAN PERIOD.
_England._—From the researches of Professor Ramsay in the Permian
breccias, we have every reason to believe that during a part of the
Permian age our country was probably covered with glaciers reaching
to the sea. These brecciated stones, he states, are mostly angular
or subangular, with flattened sides and but very slightly rounded at
the edges, and are imbedded in a deep red marly paste. At Abberley
Hill some of the masses are from 2 to 3 feet in diameter, and in one
of the quarries, near the base of Woodbury Hill, Professor Ramsay
saw one 2 feet in diameter. Another was observed at Woodbury Rock, 4
feet long, 3 feet broad, and 1½ feet thick. The boulders were found
in South Staffordshire, Enville, in Abberley and Malvern Hills,
and other places. “They seem,” he says, “to have been derived from
the conglomerate and green, grey, and purple Cambrian grits of the
Longmynd, and from the Silurian quartz-rocks, slates, felstones,
felspathic ashes, greenstones, and Upper Caradoc rocks of the country
between the Longmynd and Chirbury. But then,” he continues, “the south
end of the Malvern Hills is from forty to fifty miles, the Abberleys
from twenty-five to thirty-five miles, Enville from twenty to thirty
miles, and South Staffordshire from thirty-five to forty miles distant
from that country.”[173]
It is physically impossible, Professor Ramsay remarks, that these
blocks could have been transported to such distances by any other
agency than that of ice. Had they been transported by water, supposing
such a thing possible, they would have been rounded and water-worn,
whereas many of these stones are flat slabs, and most of them have
their edges but little rounded. And besides many of them are highly
polished, and others grooved and finely striated, exactly like those of
the ancient glaciers of Scotland and Wales. Some of these specimens are
to be seen in the Museum of Practical Geology, Jermyn Street.
_Scotland._—In the Island of Arran, Mr. E. A. Wunsch and Mr. James
Thomson found a bed of conglomerate which they considered of Permian
age, and probably of glacial origin. This conglomerate enclosed angular
fragments of various schistose, volcanic, and limestone rocks, and
contained carboniferous fossils.
