Synopsis

Excerpt from On the Vegetable Structures in Coal

Introduction. - Accepting as established conclusions the vegetable origin of coal and the accumulation of its materials by growth in situ, rather than by driftage, there still remain some questions regarding its production, to Which as yet no very satisfactory answers have been given. One of these relates to the precise genera and species of plants Which have contributed the vegetable matter required; eu other to the causes (whether differences in the plants themselves or in the manner of their preservation) Which have produced the different qualities of coaly matter observable in the different parts of the same bed, or in different beds in the same coal-field. In aid of the solu tion of these questions, and incidentally in illustration of the strue ture and affinities of the more important coal-plants, I desire to offer the results of a series of microscopical observations on the bituminous coals of Nova Scotia.
