    This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1883 Excerpt: ...of the hitter into muscovite. The analysis of the margarite, as pure, as can be selected, is given below (c 1), but also a partial analysis of the resulting muscovite, but of material, containing an admixture of margarite (c 2). d. Very remarkable specimens of corundum, usually surrounded by margarite have been found at Ilendrick's farm, Iredell county, X. C. The corundum occurs in hexagonal crystals, sometimes tapering, as if they were very acute hexagonal pyramids, with basal plane. They are very perfect and from 50 to 125mm in length, of a pale brownish or grayish white color. Many of the specimens contain numerous cavities which in most cases are small and indistinct, so that it is difficult, if not impossible, to suggest, what may have produced them, others show a hexagonal form, but in one specimen, which contains larger cavities, some from 10 to 15mm in size, very little doubt is left that the mineral which previously occupied them was corundum in crystals showing a hexagonal pyramid and prism. The corundum from Ilendrick's farm is always altered on the surface, which is enveloped by a coating of margarite, from 1 to 6ram in thickness. It is rarely subfibrous and fine scaly, but mostly compact and more or less porous. It has some black tourmaline in small crystals or crystalline groups imbedded in it, and on its surface it is beginning to change into muscovite. Where the margarite is in contact with the corundum, the latter has become rough and eaten. The analysis of the purest from this locality gave me the results (d 1), a less pure specimen was analyzed in the Laboratory of the University of Pennsylvania by Mr. Frank Julian (d 2). o. Corundum, altered into Fibrolite. a. In my previous paper I mention an observation by Prof. C. U. Shepard that at t.
