As these last arc sometimes more distinct than the minute structures, and arc necessary for their comprehension, I shall, under the following heads, notice both as I have observed them in the coals in question :â 1. The huninaj of pitch or cherry coal, when carefully traced over the surfaces of accumulation, arc found to present the outlines of flattened trunks. This is also true, to a certain extent, of the finer varieties of slate coal; but the coarse coal appears to consist of exten- sive lamina* of disintegrated vegetable matter mixed with mud. 2. "When the coal (especially the more shaly varieties) is held obliquely under a strong light, in the manner recommended by Goeppcrt, the surfaces of the laminaj present the forms of many well-known coal-plants, as Sigillaria, Stipnaria, Cordaites, Lepido- dendrun, Lejjidophloios, and rough bark, perhaps of conifers. 3. When the coal is traced upward into the roof-shales, we often find the lamina} of compact coal represented by flattened coaly trunks and leaves, now rendered distin
