In my work on The Geology of the Lake District, p. 162, I suggested that this pothole was a “giant's kettle” formed by water flowing down a crevasse in the ice.

This note is a record of the occurrence and character of some curious marks on a rock surface near Borth, Cardiganshire. We do not know of any previous description or reference to marks of this kind.

Almost all the more important teschenitic intrusions of the Edinburgh district have been examined in some detail at one time or another, but the large sill situated between Dunfermline and Charlestown is a notable exception. In the course of an investigation last autumn, the writer found, however, that, while the normal rock is not specially noteworthy, its segregations present some interesting features, particularly in view of a recent publication by Dr. G. W. Tyrrell dealing with the age and classification of the analcitic intrusions of Central Scotland.

During the summer of 1918 a party under the direction of Mr. Hamlin Brooks Hatch carried on field studies in a section of the property of the Reid-Newfoundland Company in Western Newfoundland. A number of features of general scientific interest were noted, among which was faulting of the Appalachian type. The writer is indebted to Mr. Hatch for permission to publish this phase of the results of the latter's investigations.

The Colonial Office Report on the work of the Mineral Survey of Southern Nigeria for 1905–6 gave a few details on the occurrence of bitumen in Ijebu and a paper by Mr. R. Bullen Newton published in the Ann. and Mag. of Nat. Hist., Section 8, VIII, pp. 193–208, described some mollusca which fortunately were preserved in one or two of the shallow boreholes put down to afford information on the beds then named the “Ijebu Series”. No details of the beds passed through were, however, published, and the following note is intended to supplement the Report mentioned.

The tufa that forms the subject of these notes occurs on the eastern side of Park Brook in Upper Old Park Wood, 2 miles north-west of Lydney (6 in. O.S. Sheet, 47 N.W. Glos.).

Travellers in Persia rarely diverge far from the beaten track between town and town, and there are areas in the South Persian mountains, hundreds of square miles in extent, in which there is no record of penetration by Europeans. Needless to say, such unexplored regions are frequently treasure houses of geological interest of sometimes the rarest and least expected kind.

The fossils to be described were collected by Messrs. C. Barrington Brown and R. A. Baldry, to whom I am indebted both for the opportunity of examining these forms and for the details given below of their horizon and locality, for which they are entirely responsible. The collection has been presented by them to the Sedgwick Museum, Cambridge.

A Hypothesis can be confirmed most effectively when the deductions drawn from it prove correct. When such deductions take a prophetic form, fulfilment becomes most convincing. It is gratifying thus to discover confirmation of the prognostications of a predecessor; I hope a certain ebullition of satisfaction may be pardoned since I am here in a position to use the often provocative expression “I told you so”!
