ABRAHAM GESNER REVIEW OF IIIS SCIENTIFIC WORK. 17 the locality from which it came we know it to have heen •obtained from the shales of Division 1, Band c, of the 8t. John Group. In the fauna of this band, Fig. I the only fossil that will answer to Dr. Ges- ner's " terebi-atulite " is Orthis BUliiujxl, Hartt. Examples of this fossil, in which the ears are broken off or concealed in the matrix, would resemble the terebratulite.* AT, , . Dr. Gesner also found this formation to con- Slate of St. Jo?iT>. tain plant remains in the form of a ''cactus" (or Stigmaria). In an upper set of beds other plant-remains were f(Hind. These were discovered at Little River and consisted of trunks of trees, conifera, a calamite, impressions of leaves, and a plant called a Fhytolithiisj, which probably was a Sigillaria. From the description of the locality it is evident that these plants came from the Dadox3don sandstone, of the Little River group. Dr. Gesner was thus the pioneer in making known the fauna of the Cambrian and the flora of the overlying pre-carV)Oniferoiis rocks in New Brunswick. That he did not reach the full signifi- cence of his discoveries is not at all surprising, for the district where these two classes of remains are found is a veiy complicated one; and the study of its geology for half a centur}^ past has hardly yet resulted in the unravelling of its complicated structure. Dr. Gesner's older Graywacke group is exemplified in the Huronian schists of the Coastal group and the altered schistose rocks between Cape Mispec and Emerson's Creek along the shore of the Bay of Fundy. In his fourth report we find that Dr. Gesner revised his I'eference of the Graywacke system, and upon the ground of the scarcity of organic r'emains, a few terehratula and some land plants only having been found, he classes it with the Cambrian system of Professor Sedgewick. This classification he carried out m a more
