‘become a profitable one in New South Wales. Sapphires, topazes, beryls, garnets, 
and zircons are of frequent occurrence. 
Buitpine Sronrs, Marsies, SERPENTINES, Porrery, and Brick Crays occur 
in abundance, and of excellent quality. Full particulars are given in the reports 
of the Department of Mines, Sydney, and samples of all the above-mentioned 
minerals were exhibited in the New South Wales Court in the International Mining 
Exhibition at the Crystal Palace, London.

6. On the Glacial Phenomena of the Isle of Man. By P. F. Kenpaut. 
The author briefly referred to the work done by Strickland, Forbes, Cumming, 
Clifton Ward, Horn, and Hewitt, and proceeded to give some details of the distri- 
bution of the deposits. 
The Ramsey Brooghs exhibit a section showing two beds of boulder clay 
separated by a bed of false-bedded sand. 
Beyond the Dog Mills a section is exposed showing a great series of shingly 
and sandy beds, which the author regards as a true beach. These deposits cannot 
be with certainty correlated with the Ramsey series, but the author regards them 
as probably superior to them. 
The cliffs attain an altitude of 200 feet, and extend for several miles. Beneath 
the beach series a very rich deposit of shelly clay is exposed, which has yielded 
many remarkable shells. 
At the mouth of Ballure Glen a section is visible which shows a varied series 
of glacial deposits bedded at a high angle against the clay slate. 
The cliffs near Kirkmichael are similar in character to those near the Dog 
Mills. Near St. John’s a deposit of shell-bearing sands occurs. 
Jn the south of the island many good exposures of boulder clay are visible, and 
in several cases a striated surface of limestone is to be seen. 
Dr. Tellet quotes a statement by Campbell of Islay to the effect that a gravel 
bed containing scratched stones occurs on Snaefell at an altitude of 1,400 feet. 
The Source and Distribution of the Erratics.—In the glacial tract of Ramsey 
and Kirkmichael Skiddaw slates, Carboniferous limestone, Red sandstones, and 
breccias and flints are abundant; and the author identified many granites, &c., 
from the south of Scotland, and the Eskdale granite. He could not find a single 
example of the Manx igneous rocks. 
In the south of the island Cumming had shown that local rocks were abundant, 
and had a well-defined trail coinciding with the direction of the strie, The 
foreign stones were similar to those found in the northern deposits. Boulders of 
the granite of Foxdale have been found lifted 800 feet above the natural outcrop 
in a distance of two miles. It is remarkable that no foreign stones occur at high 
altitudes in the island. 
Paleontology.—The author refers to the work of Strickland and Forbes, and 
criticises their lists. 
He identifies the Nassa Pliocena, Strick., with the Nassa serrata, Brocchi. 
4 Fusus Forbest, Strick., he holds to be distinct from the American F. cinereus, 
ay. 
"ithe author’s own collections from the island include Cemoria noachina, and 
many other shells not commonly found, but the most remarkable find is that of 
Columbelia sulcata, Sow. (by Mr. Kermode). It is a characteristic Red-Crag 
species like Nassa serrata and N. Monensis. It may be that these shells and the 
mollusca of southern range which occur in the Lancashire Drift are of remanié 
origin.
