Foliation of Metamoephio Eocks. — ^An interesting paper on the 

 foliation in the gneiss and schist of Yar-Connaught, by Mr. Gr. H. 

 Kinahan, has been read before the Geological Society of Ireland 

 during the past year, from which it appears that the foliation in the 

 metamorphic rocks of this district seems generally to follow some 

 variety of lamination, and rarely the cleavage planes, Mr. Kinahan 

 describes six varieties of foliation, one of which may follow the 

 cleavage planes, while the five others follow the lamiaation; the 

 parallel foliation being caused by parallel lamination ; the oblique, 

 by the oblique lamination ; the spheroidal, by the spheroidal lamina- 

 tion ; the crumpled, or wavy, by the crumpled lamination ; and 

 the curled, by the lamination that is round the nodules. An 

 instructive case is cited of this structure in the townland of Killa- 

 guile, where the foliation of the schist curls round nodules of gneiss, 

 the latter being found to be obliquely foliated. 



Mining. — A series of lectures on mining by Mr. Warington Smyth, 

 Pres. Geol. Society, are now being published in the Mining Journal, 

 to which we would refer our readers interested in this subject, as 

 they are carefully reported, and contain all the important points 

 connected with that branch of our practical industry. Among the 

 subjects at present described are the following : the various reposi- 

 tories in which useful minerals were to be looked for ; the distri- 

 bution and extension of mineral veins ; the physical characters of 

 vein-bearing rocks ; the direction of veins ; the shifts or dislocation 

 of veins ; the searching for veins, costeaning, hushing, etc. ; boring 

 and the different kinds of implements employed ; the various modes 

 of breaking ground ; blasting, and the kind and quality of the 

 explosive agent ; management and superiatendence of mines, etc. 



A New Dinosaubian in New Jersey. — Prof. Cope described the 

 remains of a gigantic Dinosaur from the Cretaceous Formation 

 (Greensand) of New Jersey. The bones consisted of portions of 

 the lower jaw with teeth, and of the scapular arch, including sup- 

 posed clavicles, two humeri, left femur, right tibia and fibula, etc. 

 They were found by workmen, about two miles south of Barnes- 

 boro', Gloucester Co., N. J., in a bed which immediately underlies the 

 green stratum, which is of such value as a manure. In size this 

 creature must have equalled the Megalosaurus Buchlandi, and together 

 with the Dinodon, constituted the most formidable t3rpe of rapacious 

 terrestial vertebrates of which we have any knowledge. In its 

 dentition and huge prehensile claws it closely resembled Megalosaurus; 

 but the femur, resembling in its proximal regions more nearly that 

 of the Iguanodon, indicates the probable existence of other equally 

 important differences, and its pertaining to another genus. The
