1872.] 9 to 10 feet, beneath irregular seams of blue, grey, yellow, and red clay-sand.

In Section D, west of Spencer Hoad, surface 75 feet, a layer of yellow sand, 2 feet 6 inches deep, with thin seams of red- and green-coloured sand, Avere seen between subangular gravel above and below.

Section E (fig. 3), in Lorne Terrace, surface 83 feet, shows the stratification at a spot where an unusual number of implements were

discovered. Two of these, 4 inches long and 2$1⁄2$ inches in width, pointed, and thick at the butt-end, were found close to a beam of wood, possibly the trunk of a tree, portions of which being submitted to Mr. Carruthers, were pronounced by him to be pine, "and probably Pinus sylvestris, Linn., the only indigenous species." This section, as will be seen, is composed chiefly of sand, with a strip of gravel 1 foot thick, at about 5 feet from the surface. Close to this section was also found a portion of the tooth of Elephas primigenius in the gravel, at a depth of 7 feet from the surface.

In Section F, in Chaucer Road, surface 82 feet, occurred the rhizome of a fern, the depth and position of which are worthy of notice; the deposits consisted of 6 inches surface-soil, 5 feet of brown brick-earth, passing gradually into fine yellow sand without stones, 1 foot of gravel, 2 feet of white sand, and the London Clay, Resting on this London Clay was found the piece of wood exhibited, which Mr. Carruthers has been so kind as to identify for me as the rhizome of one of our indigenous ferns, either the Lastræa filix mas, Linn., or the Osmunda regalis, Linn. One of the fronds, or a portion of the
