been observed by Dr. J. J. Harris Teall and the writer to have a thickness of 
ninety feet when the Midland Line was in process of construction from Melton 
Mowbray to Nottingham. The banks of the ancient channel through the Oxford 
Clay shales are clearly shown in open sections at the recently extended brick- 
works at Fletton, to the manager of which, Mr. A. Adams, the writer is indebted 
for facilities in the investigation.

The following Papers and Reports were read :— 
1. The Discovery of Fossils in the Jasper and Green Schist Series of 
the Highland Border at Craigeven Bay, Stonehaven. By Rosert 
CAMPBELL, M.A., D.Sc. 
Between Craigeven Bay and Garron Point occurs a series of crushed spilitic 
lavas with intercalated black shales, jaspers, and cherts. In their lithological 
characters these resemble closely the green igneous rocks and associated sediments 
which appear at intervals along the line of the Highland Boundary fault, and 
which are shown on the Geological Survey maps as of (?) Arenig age. In 
August 1909, on the occasion of a visit to Craigeven Bay in company with Dr. B. N. 
Peach and Dr. W. T. Gordon, we succeeded in finding in the black shales several 
fossils, including a linguloid shell and a bivalve phyllocarid crustacean. The 
assistance of Mr. D. Tait, of H.M. Geological Survey, was obtained in making 
a detailed search in the fossiliferous beds. Dr. Peach, to whom the fossils were 
submitted for determination, has identified the following forms: Lingulella, 
Obolella, Acrotreta, Linnarssonia, and Siphonotreta; a bivalve phyllocarid allied 
to Caryocaris and Lingulocaris ; and cases of a tubicolar worm. ‘The above genera 
are most commonly found in the lowest division of the Lower Silurian (Ordovi- 
cian) system and in the Upper Cambrian. Dr. Peach, while admitting that the 
exact horizon of the fossils is still a matter of doubt, suggests that, since 
graptolites are absent, they are more likely to belong to the Upper Cambrian 
than to the Ordovician. Whatever may be the ultimate decision as to their 
stratigraphical horizon the discovery of the above fossils leaves very little doubt 
that the boundary fault series is not pre-Cambrian. 
The (?) Upper Cambrian rocks at Craigeven Bay are separated from the 
Dalradian Schists by a reversed fault, and are overlain unconformably by Upper 
Silurian (Downtonian) strata. = 
2. The Downtonian and Old Red Sandstone of Kineardineshire.

I.—DownrToniAn. 
A thickness of nearly 3,000 feet of vertical or highly inclined strata, formerly 
included with the Lower Old Red Sandstone, but now regarded as of Downtonian 
age, intervenes between Craigeven Bay and Stonehaven Harbour. Three groups 
of beds in this succession may be particularly noted :--- 
1. At the base of the series there is a thickness of about 200 feet of breccias
