where remains of the Coccosteus, Dipterus, and Osteolepis magus, 
occur. ‘These beds are overlaid by others resembling those which 
cover the Ichthyolites of Lethen and Cromarty. 
Following the strike of the Dipple beds into Banffshire, the 
author and the Rev. G. Gordon discovered, at the Burn of 'Tynas, 
4 miles E. of Fochabers, a similar series ‘of shales and sandstones 
containing Ichthyolites, enclosed, as usual, in flattened nodules. 
Many fine specimens of species common to Lethen, Cromarty, &c., 
were procured in the highest stratum. At Buckie, the inferior 
conglomerate is partially covered by patches of a red schistose sand- 
stone, in which a tuberculated bone, similar to those in the Burn of 
Tynat, was found. The shore near this point is said to exhibit fine 
examples of a raised beach. 
From the facts contained in the paper, the author concludes, 
1. The primary strata were thrown into highly-inclined positions 
before the deposition of the old red sandstone. The elevation of 
the secondary strata to their present position, he conceives may have 
been produced by elevation in the line of the Grampians, or of the 
Great Caledonian Canal, subsequent to the accumulation of the 
Purbeck beds at Linksfield. 
2. The great conglomerate and red sandstones containing Dipteri, 
Cheiracanthi, &c., represent the Orkney, Caithness, and Gamrie 
strata in Scotland, and the inferior beds of the old red sandstone 
of England. 
3. The superimposed marly conglomerates, sandstones, and marl- 
stones, with a distinct series of fossils, are equivalents of the central 
division of the old red sandstone system to the south of the Gram- 
pians, and in England. 
Lastly, That there are no indications of the coal strata. 
Dr. Malcolmson terminates his memoir by stating, that the Gam- 
rie Ichthyolites clearly belong to the old red sandstone, and not to 
the coal measures. 
This being the last evening of the Session, the Society adjourned, 
at the conclusion of its business, to Wednesday, the 6th of No- 
vember.
