underlying quartz-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 CuUen 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 Red 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 hi other parts of the ISTorth 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 

 Eed Sandstone of Berridale, and is succeeded by the gneiss and folded 

 white quartz-rock of the Scarabins. From the Scarabins to Strath-Naver 

 granite and gneiss alternate in laminar masses, dipping south-east towards 

 the Scarabins, here and there bearing unconformable outliers of Old Red 

 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 Rev. 

 David Honeyman. (Communicated by the President.) The author, at the 

 request of the Provincial Government Commission for the International 

 Exhibition, made some observations on the 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-bearmg 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 

 Rocks of New Brunswick, Nova Scotia, and Cape Breton." By J. W. 

 Salter, Esq., E.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 n&w Eurypterus, E . piilicaris . Other remains of 

 JEurypteri have been sent also by Dr. Dawson, from the coal-measures of 

 Port Hood and the Joggins ; and with these a new Amphipod, JDiplostylus, 

 having some characters of alliance v/ith Typhis and BracJiyocelus. 



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 JEuryptenis by Dr. Wieskowski and Professor J. Hall, Mr. Salter ex- 

 plained some formerly obscure points in its structure, and proceeded to 

 describe the E. Scouleri, Hibbert, from the Carboniferous limestone of 

 Scotland, and the Upper Old Red Sandstone of Xilkenny ; the E. (Ar- 

 tkropleura) mammatus, sp. nov., from the Upper Coal-measures near Man- 

 chester ; and E. ? [Arthropleura?) ferox, sp. nov=, from the Coal-measures 

 of North Staffordshire.
