The excavations for the foundations of the new Infirmary in the grounds of Watson's Hospital, Edinburgh, have disclosed several Boulders, which appear lying in the Diluvial-clay. This is a marly clay, and has been dug to the depth of about five feet, in several horizontal terraces, down the slope from north to south. These Boulders were of sufficient size to be left behind in situ by the labourers, and about six large ones were found in the north and twelve in the south area of the grounds. They were of trappean rock chiefly, being rounded on the angles and sides, and of a dark green crystalline structure internally, A large one in the north area was of a metamorphic granitic character; one in the same area of a buff-coloured sandstone; and another in the south was composed of the same rock, and grooved also.

In a paper on a comparison of the drift of Ireland with that of Lancashire, the author Prof. Hull states, that he recognized the equivalents of the English beds in the drift cliffs at Killiney, Co. Dublin, and in the Geol. Mag. for March, 1872, Mr. J. Geikie has quoted Prof. Hull: I therefore request leave to say a few words about the gravels of Ireland, more especially as Mr. Geikie seems to have mistaken my notes on the Irish drift, making it appear that I believe the “Esker Gravels” contain similar marine fossils to those characterizing the “Manure Gravel” of the Co. Wexford. Such a statement, however, would not bear investigation.

During a visit to Crayford in April, under the guidance of my friend Mr. Dawkins, I obtained a worked flint from Slades Green Pit. The discovery seems worth recording, on account of the presumed early age of the deposit in which it occurred. Mr. Evans has kindly looked at the specimen, and considers it decidedly to have been worked, so that there is no room for doubt upon that head. I picked the implement out of a band of rounded flint gravel, lying beneath the sandy stratum which contains abundance of shells, and among them the Corbicula (or Cyrena) fiuminalis and Unio litoralis, together with many mammalian remains.
