When we find at the sides of veins, the veinstone rent into laminæ, as I tried to represent in Plate XX. of Vol. IV. it is easy to think of the fracture as violent, and of the disruption of the vein as sudden.

As none of the figures hitherto given of the genus Eophyton show either its internal structure, or articulations of its stems, and as I am in possession of a specimen from the Lower Arenig Rocks, of Ramsey Island, near St. David's, which resembles in some respects the Eophyton Linnœanum Torell, but which shows both articulations of the stem, and an internal vascular structure, a description of the species may probably be useful, and may tend to elucidate the true nature of Eophyton, concerning which so much doubt seems to exist at present.

In the number of this Magazine for July, 1866, p. 293, I ventured to characterize as “preposterous,” the opinion advanced by Mr. D. Mackintosh in two preceding papers (Geol. Mag., Vol. III. p. 69, and p. 163) that the very numerous terraces that occur on the sides of the Chalk and Oolitic hills of the southern and western counties were, “without doubt, raised Sea-beaches,” affording, therefore, evidence of the very recent elevation of these hills from beneath the sea-level, since the complete excavation of the existing valleys.

The superficial deposits of the Co. of Wexford, containing a rich marine fauna, have been referred to in Professor E. Forbes's Memoir on “The Geological Relations of the existing Fauna and Flora of the British Isles.”

Sixteen years have now passed since Mr. Davidson's Monograph of the British Secondary Brachiopoda appeared, and as numerous additions have been made from time to time, it is my present object to collate the scattered records of the additional species, and to supplement such information by notices of new or little known forms.

Having seen in the September Number of the Geological Magazine (p. 408), the Catalogue of Types of Fossil Fishes in the collection of my valued friend and fellow-worker Sir Philip de Malpas Grey Egerton, Bart,, M.P., with whom I have collected for so long a time, it occurred to me that the addition of the list of the type specimens of genera and species in my own collection would be a useful supplement to Sir Philip Egerton's carefully prepared catalogue, and might not be wholly unacceptable to the student in Palichthyology. I therefore beg to subjoin it, and, in doing so, to reecho the sentiment expressed by my friend, that my collection, like his own, although a private one, is always accessible to the student in Geology or Palæontology who may deem it of sufficient interest to visit Florence Court in order to study it.

During the past summer, I had the good fortune to detect Albite (Soda-feldspar) in some blocks of granite in the wall of the west pier at Kingstown, Co. Dublin. As the pier is built of rock from the Dalkey quarries, the mineral can be referred, with tolerable certainty, to its original locality. I was induced to look closely at the above-mentioned blocks, through noticing that they contained a mineral of a purple colour; this proved to be fluor, which occurs sparingly throughout the Leinster granite. Associated with the fluor was a pretty considerable quantity of a white mineral, occurring in aggregations of minute crystals; this appeared to me to be so like Albite that I considered it deserving a careful examination.
