The high temperature of the Bath springs, their saline character, and their content of radioactive substances all combine to show that the waters must rise from a great depth. If we take the average temperature of normal spring water at 50° F. and that of the Bath Springs at 120° F., this gives an excess of 70° above the normal. Accepting the usual temperature gradient in England as being 1° F. for every 64 feet of depth, this makes the position of the: ultimate source 4,480 feet below the surface. This figure must, however, be regarded as a minimum, since no allowance is here made for cooling on ascent. This is an unknown factor, and sufficient data are not available for a reliable estimate. In any case the depth is unlikely to be less than 5,000 ft. and is probably far greater. This water, then, is obviously something very unlike the ordinary surface springs fed by atmospheric waters circulating in the upper layers of the earth's crust.

The Scotland Beds of Barbados have been considered as a rule to be very unfossiliferous, but Mr. A. Menzies, Geologist to the Union Oil Company, has traced at various places a thin conglomeratic band which contains fossils.

Professor Gregory, in a very interesting paper published in the Transactions of the Faraday Society, has advanced various arguments against the theory of the magmatic origin of the Sudbury nickel deposits and has quoted several authorities as opposing that theory. His brief account of the subject presents, unintentionally of course, only one side of the controversy in regard to those ores, and lest the deservedly great authority of his opinion should seem to settle the question, I wish to place before English geologists an outline of the arguments on the other side.

The following article includes a description of the larger Foraminifera of the Upper Ranikot Series of Sind in Western India. The specimens examined consist of a collection made by Mr. D. Dale Condit and by myself in the winter of 1923, as well as material kindly loaned by the Indian Geological Survey. I wish to thank the directors of the Whitehall Petroleum Corporation for permitting me to make use of the specimens collected during a geological reconnaissance undertaken on their behalf. Of the specimens figured those loaned by the Survey have been returned to Calcutta, and the remainder placed in the Sedgwick Museum, Cambridge.

The area examined occupies about 12 square miles in South Cardiganshire bounded inland by a line joining the hamlets of Sarnau and Nanternis, and extending along the coast from the stream crossing Penbryn Sands in the south to New Quay in the north.
