238 GLEANINGS—REPORTS. 
Drirt oF THE West Mipnanps.—An important paper on this subject 
by Mr. D. Mackintosh, F.G.8., appears in No. 139 of “‘ The Quarterly 
Journal of the Geological Society,” just published. Three sources of 
boulders are indicated :—(1) Granite of Criffel, &c., in Kirkcudbrightshire ; 
(2) Eskdale Granite and Felspathic Rocks, from the Lake District ; (3) 
Felstones, &c., from the Arenig Mountains of North Wales. The agency 
of transport is believed to have been floating ice. On the south-west of 
the Clent Hills, between Hagley and Bromsgrove, and in less numbers 
near Birmingham, are many Arenig blocks; between Bridgnorth and 
Wolverhampton, and on Bushbury Hill enormous numbers of boulders 
(chiefly Criffel) occur. Here a warm current may have melted the bergs. 
The “ great Cannon Hill Park boulder” at Birmingham, is referred to the 
Arenig area. In the discussion which followed the reading of the paper, 
Mr. J. F. Campbell instanced the Straits of Belleisle, almost in the same 
latitude, as a place where a similar state of things now existed.

hitherto recorded as found in Sweden and Germany only. At the sathe 
meeting, Mr. Bolton exhibited the somewhat rare Entomostracon, Polyphemus 
pediculus, which oceurs at the present time in enormous quantities, along with 
Volvox globator, in Sutton Park; also, Ceratium (Peridiniwm) cornutum, one of
