underlying qnartz-rock of great thickness, conformable, and folded with 
it, and seen in anticlinals at Melrose, Banff, and Dunidich, and still more 
in an arch between Cullen and Buckie. Two folds of limestone, obscurely 
stratified and not persistent, occur with the schists at the Burn of Boyne 
and Dunidich. The dykes of syenite, of granite, and of serpentine (Port- 
soy) were also pointed out in this section, as well as two outliers of the 
Old Eed deposits at Dunidich and Cullen. The metamorphic rocks above 
mentioned have a predominating south-east dip, and the folds hang over 
to the north-west ; but the author regards these strata as holding a re- 
versed position, the gneissose and grauwacke strata being really the upper- 
most of the series, as in other parts of the jS"orth of Scotland. The sec- 
tion from the sea at Berridale, across the Scarabins to Strath-Naver, was 
next described. Here the granite of Bean-na-aiglesh succeeds to the Old 
!Red Sandstone of Berridale, and is succeeded by the gneiss and folded 
white quartz-rock of the Scarabins. From the Scarabins to Strath-]^^ave^ 
granite and gneiss alternate in laminar masses, dipping south-east towards 
the Scarabins, here and there bearing unconformable outliers of Old Eed 
Sandstone. In this case also the author pointed out that a reversed dip 
obtained, by which the really uppermost gneissose rock was made to ap- 
pear lower in position than the quartzite. Professor Harkness further al- 
luded to the conformability of the granite with the strata in this district, 
and to the probability of its being rather the result of an excessive amount 
of metamorphic action than of plutonic origin. 
2. " On the Geology of the Gold-fields of Nova Scotia." By the E-ev. 
David Honeyman. (Commnnicated by the President.) The author, at the 
request of the Provincial Government Commission for the International 
Exhibition, made some observations on th« auriferous rocks at Allen's and 
Laidlow's farms, near the junction of the Halifax and Windsor and the 
Halifax and Truro railways. He found chloritic schist, with vertical auri- 
ferous quartz-veins, and a gold-bearing horizontal quartz-vein (the "bar- 
rels" of the miners) lying on the schist and overlaid by quartzite and 
gravel. By the neighbouring railway sections the chlorite-schist is seen to 
alternate in broad bands with quartzite, and to be associated with granite. 
The- author thinks there is reason to believe that the quartzite may be of 
Lower Silurian age. 
3. " On some Fossil Crustacea from the Coal-measures and Devonian 
Eocks of New Brunswick, Nova Scotia, and Cape Breton." By J. W. 
Salter, Esq., F.G.S., of the Geol. Surv. Great Britain. One of the Devo- 
nian fossils is apparently allied to the Stomapods, and is named Amphipel- 
tis paradoxus by Mr. Salter ; it was obtained by Dr. Dawson near St. 
John's, where it occurred with plant-remains ; another Crustacean fossil 
from the same locality is a -aev^ Eurypterus, E.puUcaris. Other remains of 
Eurypteri have been sent also by Dr. Dawson, from the coal-mcasnres of 
Port Hood and the Joggins ; and with these a new Amphipod, Diplostylus, 
having some characters of alliance with Typhis and Bracliyocelus. 
4. " On some species of Eurypterus and allied forms." By J. "W. Sal- 
ter, Esq., F.G.S., etc. After alluding to the late and complete researches 
on Eurypterus by Dr. Wieskowski and Professor J. Hall, Mr. Salter ex- 
plained some formerly obscure points in its structure, and proceeded to 
describe the E. Scou'leri, Hibbert, from the Carboniferous limestone of 
Scotland, and the Upper Old Eed Sandstone of Kilkenny ; the E. (Ar- 
throplem^a) mammatus, sp. nov., from the Upper Coal-measures near Man- 
chester ; and E. / {Arthropleura ?) ferox, sp. nov., from the Coal-measures 
of North Staffordshire.
