Abstract

The nodules described in the following paper occur in
certain bands in the upper members of the strata disclosed
at Duff's quarry, in Forster-street, New Town. The
nodule-bearing bands appear to be unfossiliferous, but
both above and below them are other bands carrying
numerous fossil impressions, including Alethopteris
australis, Thinnfeldia obtusifolia, Phyllotheca, &c. The
whole series of bands is just below the horizon of the
New Town Coal Measures. The beds in which the nodules
are found are grey and blue-grey in colour, traversed by
thin layers of darker hue, thus giving rise to a banded
structure ; they may be described as a calcareous sandstone
of fine texture, fairly tough, and showing little or no
tendency to split along the planes of banding. Includes two photographs
