The writer also saw these singular bodies, and assisted in getting good photographs of them. Weathered transverse sections show well-defined concentric rings of various colors, measuring from the eighth of an inch to three inches in thickness, but there are no radial lines. (See figure, p. HI.) The people in the vicinity of the quarries where these trunk-like forms are found were much disappointed when told by Dr. Selwyn that they were only concretions. On the other hand, many of the fossils found in the Chazy and Trenton formations of Ottawa were at one time supposed to lie concretions, but are now known to belong to the family of the Monticuliporidai (Micro-Pakeontology, by Arthur H. Foord, page 24, plate VI.). It is, therefore, important that all such nodular or concretionary-looking forms from the auriferous slates of Nova Scotia should be microscopically examined before coming to the conclusion that they are organic remains, and especially before assigning names to what on thorough examination turns out to be of inorganic origin. II.--Evidence Of The Post-glacial Extension Of The Southern Coast Of Nova Scotia.--By W. H. Prest. Read Feb. St/t, ISM.) At various points on our southern coast are deposits of peat and iuarsh mud below high water mark. Tiiese often contain roots and stumps of trees now existing in this Province, and, by their position and by other circumstances, point conclusively to a late subsidence of the laud. Similar deposits have been referred to by geologists as existing on the coast of Cumberland County, and the same conclusion has been drawn from their occurrence there. I will here give further evidence which may be of value in future investi...
