before the Belfast Natural-History and Philosophical Society, states
" that the plant impressions are in the red earth or lithomarge lying
on and in this haematite-conglomerate." These are inaccuracies, and
imply that the plants are associated with masses which are the pro-
ducts of metamorphism.
Fig. 3. — Section at Ballypalidy .
The section at Ballypalidy, west side of railway (fig. 3), in descending order is as follows : —
1. Glacial Drift 12 feet.
2. Conglomerate-bed, composed principally of spheroids of iron-ore, in a ferrugineo-argillaceous paste, with which are associated fragments of basalt and greenstone. Occasionally thin bands of an arenaceous clay with plant-impressions appear among the conglomerate ; otherwise there is no appearance of stratification in this bed 10-12 feet.
3. Plant-bed, a reddish-yellow ferrugineo-arenaceous shale, distinctly laminated, with fragments of plants along the planes of bedding 4-8 inches.
4. The so-called plant-bed passes into a browner stratum, more argillaceous, the darker colour being due chiefly to an admixture of finely disseminated carbonized vegetable fragments. Plant-remains occur also in it; and patches of lignite increase in frequency downwards. Total thickness of plant-layer and this bed 3 feet.
5. Lignite 1 foot.
6. Amygdaloidal basalt.
The conglomerate is of irregular thickness, thinning out towards the S. W., whilst the finer sediments below increase slightly in
