It should be understood that the Carboniferous system in Nova Scotia consists of the following members :— " (1.) Tlia Upper Coal Fonnatiun. " (2.) The Middle Coal Formation. " (3.) The Millstune-grit Series, represented in Nova Scotia by red and gray sandstone, shale, and conglomerate, with a few fossil plants and thin coal seams, not productive. " (4.) The Carboniferous Limestone, with the associated sandstones, marls, gypsum, etc., and holding marine fossils, recognised by all palajontologists who liave examined them as Carboniferous. "(5.) 'The Lower Coal Measures, holding some but not all o.' the fossils of the Middle Coal formation, and thin coals, not productive; but difYerlng both in flora and fjiuna from the Upper Devonian, which, in New Brunswick, they overlie unconformably. "The principal, though not the only point in which Mr Lesley differs from Logan, Lyell, l^rown, and Dawson, is his entire omission of No. 5 of the above scries, and placing No. 3 in its room, as the representative of the Lower Coal measures of Virginia and Penn- sylvania. I have, I think, already made this sufficiently j'lain in the fifth of my objections, already published ; but may add here that fossils as well as stratigraphi ;al position establish the real equivalency of
