and described a few species of Coniferœ; and Professor King, in 1844, published an elaborate paper on the characters of Sigillaria. The species in the Newcastle Coal Measures have been carefully tabulated, with references, by Professor Morris in his "Catalogue of British Fossils" in 1854; and also by Mr. Howse in his "Synopsis of Organic Remains," in 1865. Some account of the Mountain Limestone Flora was given by myself in 1853, in Dr. Johnston's Botany of the Eastern Borders."
Of the few fossil remains of Mammalia which have been observed in superficial deposits, Mr. Howse has given an account in the "Transactions of the Tyneside Naturalists' Field Club," Vol. IV., page 111. Probably remains of the beaver may be discovered lurking in some of our bogs, as they have been found in the adjoining county of Roxburghshire.
