Felspar grains are not unfrequently present, with scales of mica and minute chlorite and epidote. Chemical analyses of some varieties were also given.

Page 83 - President, in the Chair. The following communications were read : — 1. " On the Constitution and History of Grits and Sandstones." By John Arthur Phillips, Esq., FGS In the first part of this paper the author described the microscopic and chemical structure of a large series of grits, sandstones, and, in some cases, quartzites, of various geological ages, noticing finally several sands of more or less recent date. The cementing material in the harder varieties is commonly to a large extent siliceous....
Page 282 - million of foot pounds" kept in the box during its seventy-two hours' journey from Paris to Glasgow was no exaggeration. One of the four cells, after being discharged, was recharged again by my own laboratory battery, and then left to itself absolutely undisturbed for ten days. After that it yielded to me 260,000 foot pounds (or a little more than a quarter of a million). This not only confirms M. Reynier's measurements, on the faith of which your correspondent's statement was made ; it seems further...
Page 118 - Pcrifera vitrea, which find their nearest representatives among the Ventriculites of the white chalk. The Echinoderms of the deeper parts of the Atlantic basin are very characteristic, and yield an assemblage of forms which represent in a remarkable degree the corresponding group in the white chalk. Species of the genus Cidaris are numerous ; some remarkable flexible forms of the...
