(v) the so-calkd talc-granite ; and (vi) diabase, among which, at 

 Arosa, is a variolite. The schistose rocks (ii) are common in the 

 neighbourhood of the East Alpine serpentines, and in this region the 

 latter rock passes down on the western side into ophicalcites, which 

 are followed by a confused mass of layers of serpentine, alternating 

 with reddish calcareous or argillaceous bands. These, the author 

 considers to indicate a physical condition rather than a geological 

 horizon. With the red and green schistose rocks, which he refers 

 to the Mittelbildung, radiolarian cherts are associated. These have 

 been examined by Dr. Gr. J. Hiude, who states that the radiolaria 

 are not sufficiently well preserved for specific identification, but have 

 rather a Jurassic facies, though they also resemble radiolaria, 

 described by Prof. Parona from Cesara, which that author regards 

 as at any rate not newer than Lower Trias. 



The author discusses at length the physical structure of the 

 district. The general trend of the Davos Valley is rather oblique 

 to that of the greater rock-masses, which, however, is somewhat 

 irregular. He shows that these (which have a general dip towards 

 the south and east) form three great acute and rudely parallel over- 

 folds, the westernmost being the most complicated ; of this fold the 

 serpentine forms a part. It is more recent than the crystalline 

 schists and the Casanna Schiefer, and is associated with the red and 

 green schistose rocks already mentioned, in a way which he con- 

 siders indicative of intrusion ; but it nowhere cuts the Haupt- 

 Dolomit. Accordingly he considers it to be later than the Yerrucano, 

 and not earlier than the middle part of the Trias. Certain 

 crystalline breccias occur in the neighbourhood of the serpentines ; 

 these the author considers to be due to earth-movement, and he 

 goes on to give reasons for regarding them as the equivalent of the 

 Casanna Schiefer of other localities. There is, in his opinion, no 

 evidence of the presence of post-Jurassic strata such as Prof. Stein- 

 mann believes to exist. 



2. ' Contributions to the Geological Study of County Waterford. — 

 Part I. § I. The Lower Palaeozoic Bedded Rocks of the Coast.' 

 By F. P. Cowper Reed, Esq., M.A., P.G.S. 



This paper opens with an account of the previous publications on 

 the geology of the district, and then goes on to describe the sections 

 exposed along the coast at the following localities : — Raheen and 

 Newtown Head, Tramore Bay, Garrarus and Kilfarrasy, Annestown 

 and Dunabrattin, Knockmahon, Ballydouane Bay, and Killelton 

 Cove to Ballyvoyle. These sections expose shales and limestones 

 with abundance of igneous rocks partly interbedded, but mainly 

 intrusive ; and the author is able to make out the following suc- 

 cession of rocks, tabulated in descending order : — 



4. Raheen Series. Mudstones, slates, felsites and tuffs, and fossiliferous 



shales. 

 3. Carrigaghalia Series. Grraptolitic shales, thin flags, cherts, tuffs, and 



felsites. 

 2. Trainore Limestone Series. Divided into three stages. 

 1. Tramore Slates. Calcareous and argillaceous slates.
