Rev. H. Lloyd, "On tlie Alfeetions of Polarized Light reflected from and 
transmitted by thin plates."

Terebratella." 
Dr. Buist, E.G.S., "On the Geology of Lower Egypt.'; 
The President read a letter from Dr. Dawson, P.G.S., intimating certain dis- 
coveries wliich he had made of a land-shell and reptiles in the South Jog-

Professor Nicol, F.R.S.E., gave an able and interesting notice on the " Re- 
lations of the Gneiss, Red Sandstone, and Quartzite in the north-west High- 
lands," illustrated by various sections. Professor Nicol had visited the High- 
lands, and had arrived at a dill'erent conclusion as to the succession of certain 
crystalline and sub-crystalline rocks from tliat arrived at by Sir R. Murchison. 
He contended that the great series of rocks in question were of older date tlian 
that assigned to them by Sir R. Miu'chison, and endeavoured to prove, by a 
reference to the sections which he exhibited, that the order of superposition 
which he advocated was the correct one. 
Professor Huxley read a paper on " Newly discovered Reptilian re- 
mains from the ueighbovirliood of Elgin." 
Rev. Professor Sedgwick, " Ou Faults in Cumberland and Lancashire." The 
object of the Professor's description of the faiJts in Cumberland and Lanca-

position of the strata. 
Professor Rogers, " Some Obseiwations on the Parallel Roads of Gleiiroy," 
in which he described the leading features of the district, and indicated as "liis 
opinion that the shelves or grooves on the surface of the hiUs had been formed

Adolphe Radiguel, C.E., " On a Fragment of Pottery found in a Superficial 
Deposit." 
M. Gages, " On the Results Obtained by the Mecanico-chemical Examination 
of Rocks and Minerals." M. Gages had invented a new mode of examining 
metamorpliic rocks. Instead of reducing them to powder, he simply broke 
them down and then submitted them to chemical tests. By this means some 
remarkable residts had been obtained. 
Mr. C. G. Tliost, " On tlie Rocks and Minerals on the Property of the Mar- 
quis of Breadalbane." 
Mr. Brady, " On some Elepliant-remains at Ilford." The chief of these was 
the tusk of an enormous mammoth, identical with the Siberian mammoth. 
Remains of coniferous and otlier plants yet existaut were found in the same

Mr. J. Miller, " On tlie Age of tlie Reptile sandstone of Morayshire."
