Abstract
In some notes communicated last year to the Geological Society, I stated the results of observations on the gypsiferous formation of Nova Scotia, tending to confirm the views of Mr. Lyell respecting the age of that series of rocks. In introducing those notes, it was stated that the carboniferous strata of this province may be included in three groups; first, the gypsiferous or mountain limestone formation; secondly, the older coal formation; and thirdly, the newer coal formation: of these the two former have almost exclusively attracted the attention of geologists, the latter having been in a great measure neglected. In connection with the Pictou coal field, however, and probably also in other parts of this and the neighbouring colonies, the newer coal formation is an extensively distributed deposit, often attaining considerable thickness, and, though not containing valuable beds of coal, ironstone, or gypsum, yet so associated with the rocks including these minerals, that a knowledge of its structure and relations is essential to their satisfactory investigation. In a palæontological point of view also it possesses considerable interest; as its fossils show the continuance of the coal flora during the deposition of a series of red sandstones newer than the great coal measures; and also the co-existence of that flora with terrestrial vertebrated animals.
