Book excerpt: Excerpt from A Summary of Progress in Mineralogy and Petrography, in 1887 Th'eories proposed to account for these bodies are discussed, and filiat one is accepted which regards them as the result of the alteration of spherulites, in preference to the one in which a vesicular origin is assigned them. The present writer thinks that a study of the phenomena attending the alteration of spheru lites will explain satisfactorily the occurrence of the hollow spherulites. In many of these there is often found a little patch of felsitic material with a radial structure, and from this Mr. Cole argues that the whole body was once of the same nature; and that the greater part of the original filling has been removed by decomposing agents, probably through the channels afforded by perlitic cracks. He then examines 3 many of the spherulitic rocks of Great Britain and some from localities in Europe and America, and finds that his views are on the whole confirmed. Pro fessor Milne, in a recent number of the Transactions of the Seis mological Society of Japan, ' states that the lavas of the Japanese volcanoes (one hundred in all, of which fony - ei ht are still active) are chiefly andesites, the hornblende varieties 0 which frequently contain quartz. Those containing olivine approximate to basalts, though true basalt is rare. A critical study of these rocks is now being made by members of the Japanese Survey. A microscopical examinations of the volcanic ash ejected during the recent eruption in New Zealand shows it to contain fragments of limpid plagioclase crystals, dark green pleochroic hornblende, sometimes fibrous, and extinguishing at biotite and a golden-colored mica in well-formed crystals of hexagonal out line, pyrite, magnetite, broken pieces of sulphur, and glass con taining crystallites arranged in flow-lines. By treatment of the granite-porphyry from Beucha with hydrofluoric acid, and then the residue thus obtained successively with various other acids, Kronstshol'is has succeeded in isolating from it small colorless isotropic crystals with glassy inclusions. These crystals possess a specific gravity greater than 3, a refractive index equal to that of garnet or spinel, and show, before the spectroscope, the lines of iron, calcium, magnesium, and aluminium. The author calls attention to the similarity between these crystals and those which he obtained in a like manner from the phonolite7 of Olbruck, and.

Book excerpt: Excerpt from A Summary of Progress in Mineralogy and Petrography in 1891 Water, and above this temperature is decomposed. Just below 260 the hydrate is biaxial, while above this temperature the anhydrous residue is uniaxial. Other zeolites yield similar results. These lead to the conclusion that they all consist of a nepheline, pyroxene, or feldspar-like silicate, combined with meta or orthosilicic acid, and also an amount of water varying with the temperature. The crystal water may be driven off at high temperature, and taken up again at a lower one, and the various hydrates obtained by the successive steps may possess different crystallographic properties. After a certain amount of loss the minerals refuse to part wrth more water, which is regarded as chemically combined with silica in the silicic-acid portion of the combination. The author determines incidentally the solubility of several of the zeolites in different solvents, and concludes his paper with a table giving the supposed composition of the members of the group. Heulandite is represented as natrolite as etc. Messrs. C. And G. Friedel, n by the action of lime on mica in the presence of calcium chloride, obtained small crystals of anorthite, and by the action of soda and sodium sulphate on the same mineral produced little prismatic crystals of a substance differing from nosean in the addition of two molecules.
