498 REPORT—1883, 
speculative reasoning is not in accordance with what we know of the actual opera- 
tions of nature) Mr. Stirrup thought would be a retrograde movement in the history 
of geology, and that it would be safer to adhere to those sound principles of the 
Huttonian philosophy which considered the little causes, long continued, as com- 
petent to bring about the greatest changes of the earth. 
4, On the former Physical Condition of Glendale, Northwmberland. 
By G. P. Huaues. 
The author exhibited horns of Bos primigenius (urus) and antlers of the red 
deer, both found fifty years since in a bog at Middleton Hall, south of Wooler. The 
latter has twenty-three points, and is believed to be the largest in Great Britain. 
They were found fourteen feet from the surface in marl, underlying peat. The bog 
in which they were found will now be explored, in hopes of finding more remains. 
The author believes that this and similar deposits elsewhere found along the valley 
indicate that Glendale was once a lake. 
5. On a Conglomerate with Boulders in the Laurentian Roeks of North Uist, 
Scotland. By James THomson. 
The author described pebbles and boulders, up to 5 ft. 10 in. in diameter, 
unstratified with the gneiss and granitoid gneiss of Harris and of Loch Maddy, in 
North Uist. The included fragments are of hornblendic, gneissic, and granitoid 
rocks. The author believes these to belong to the Laurentian series and not to 
a later division of the pre-Cambrian rocks. 
6. Ona Coral Atoll on the Shore-line at Arbigland, near Dumfries, Scot- 
land. By James THomson. 
The author briefly described the stratified rocks of the shore-line in the neigh- 
bourhood of Arbigland, and stated that a portion of these stratified rocks consisted 
of linear coral reefs extending for two miles along the coast line. In Arbigland 
bay the reefs are more or less circular in outline, recurving at either extremity. 
These are overlain by a series of reefs which are circular in outline, in which he 
found several species of the fasciculate varieties of Lithostrotion ; also Syringopora, 
Aulopora, Cladoconus, and Monticulopora. And in the dark calcareous shale in 
the interior of the encircling reefs are numerous species of the Astrai-formed 
varieties of Lithostrotion, in dense formed masses varying in size from 1 in. to 
11 ft. 10 in. in diameter. He also discovered embedded in the shale a species of 
fossil sponge, which has been described by Mr. Carter as Pulvulus Thomsoni. One 
specimen of this sponge measured 11 in, long by 5 in, broad. These facts imply 
conditions similar to those described by Dana, and Darwin in the Atolls of the 
present day. The Atoll at Arbigland is the first one recorded of Carboniferous 
age. A detailed description, with a list of fossil remains, will be published at no 
distant date.
