(Read January 17, 1S81.; I WISH to bring to the notice of the Institute the occurrence lin Nova Scotia of a mineral resembling Lievrite, as described by [Sir William Logan in his Geology of Canada, p. 4G.5. The mineral as found in this Province came from Gabarus, in Ithe Island of Cape Breton, and was given to me some years ago [by a man who thought it was an ore of Molybdenum. On examination I found the colour to be black, with a faint [olive tinge; fracture uneven, glistening, and subvitreous ; hard- iness, G ; specific gravity, 3.75 ; streak gi'eyish. The specimen was faintly magnetic, but this property may have been more strongly manifested when it was fresh. It fused ])efore the blow-pipe to a dark magnetic slag, and gave the ordinary iron [reactions. It gelatinised slightly with Hydrochloric acid. My analysis of the specimen is as follows, and for the sake of [comparison, is placed beside that given by Sir W. Logan, as cited above : f ;s i :i iJi 254 LIEVRITE IN NOVA SCOTIA — GILPIN.

I do not know the exact locality ; consequently, some doubt may arise as to its pioper geological age. Mr. J^letcher, of the Canadian Geological Survey, .states in his Repoi't of Progress, 1875-7G, that this part of Gabarus Bay is occupied by felsites of Lauren- tian age, which is confirmatory of the age assigned to the mineral by Sir W. Logan. The description in the Geology of Canada is as follows : " It contains some black mica, and portions of red garnet, and forms a mineral of a velvet black colour, weathering rusty red, but having within a shining submetallic lustre. Its hardness is 0.5, and specific gravity 4.15. Powder, yellowish ash-gray. Slightly translucent on the edge, and strongly magnetic. Brittle with an uneven fr.icture, and cleavage imperfect in two direc- tions oblique to ore another. Before the blowpipe it intumesccs and yields a black slag ; with hydrochloric acid it gelatinises. From its composition (given above) not less than its physical characters, this substance i'. regarded as a variety of Lievrite. It probably forms a bed in the Laurentian series, as a boulder of it, nearly a foot thick, was found near Ottawa, but the rock has not been observed in situ." The analyses of this mineral from Elba, as given by Dana, all show the presence of 11 to 15 p?r ctat. of Lime, which is pre- sent in smail quantities only in that from Canada.

The occurrence of a mineral, however, in Nova Scotia, resembling it so strongly, would show that it may be most properly considered a variety of lieorite. The mineral is principally found in Elba, at Rio la Marina and Cape Calmite, where it occurs in disseminated and grouped crystals. At one time the crystals were abundant, the finer specimens are now rare, and bring extravagant prices. On this Island it occurs in dolomite with pyroxene, etc. It has been found in Siberia, Silicia, and Norway. In America it w^as formerly obtained in Cumberland, Rhode Island, and Somerville, Mass., in long slender slightly rhomoboidal prisms, longitudinally striated and sometimes presenting terminal faces. These prisms are implanted on granular quartz with minute crystals of magnetite, but the supply now appears to be exhausted. The mineral I have shown you this evening is not considered to exist in quantities which would lead to any hope of its find- ing an economic value. Its decomposition, however, would supply peroxides of iron, and compounds such as these may have formed a most important source for man}' valuable iron ore deposits occurring in strata succeeding the Laurentian. Art. IV.— On the Birds of Prey of Nova Scotia. — By J. Bernard Gilpin, A. B., M. D., M. R. C. S. (Head \Oth Jan.y 1881.) In making this list I have personally identified, with one or two exceptions, every species in it. I will not say that no other specimen may be added, but that if hereafter noted, it will be a very rare one to have escaped my notice of more than thirty years. Personal identification of each species also by the writer,, even if in a narrow limit, adds always to the interest and value of a paper. In classification I have used Key to N. A:.\erican Birds, by Dr. Coues, 1872, of the value of which it scarcely needs h .1 m 1 1 M ■ m JHI 4 i.
