Stated Meeting
1893.1 SEW YORK ACADEMY OF SCIENCES. 75 single day-might, in his long experience, with every possibility be depended on. SECTIONOF ASTROXOMYAND PHYSICS. Professor REESin the chair. The secretary read a paper by Mr. Herman S. naris, Fellow in Astronomy at Col‘umbia Col- lege, entitled “ Sote on Bessel’s determination of thc relative parallaxes of p and fl Cassiopei:e.” Mr. naris had re-reduced the observations of right ascension difference of the two stars made by Bessel in the years 1814 to 1816, and printed in Engel- inanii’s “Abhandlnngen ron F. W. Ijesscl,” vol. 2, p. 215. Em- ploying the duwers, proper motions of the two stnrs and introducing into the Besselian equations a term to allow for dif- ferential proper motion, Mr. Davis arrives at the value : Parallax of p relative to t) Cassiopeiz =+0. ”02 5 Off 24. Where Bessel had obtained -- 0 “.12 5 Off .29. It will be seen that the new reduction diminishes materially the probable error of the result, in spite of the fact that the in- troduction of the proper motion term into the parallax equa- tions has lessened the weight of the determination of the parallax itself. Mr. Davis’ result is in very close though perhaps acci- dental accord with that derived from Mr. Rutherfiird’s photo- graphic measures, which was + 0” .04 (Annals N. Y. Academy, rol. viii., 11. 11). Professor William Hallock read a paper on ‘’ The Theory of Geysers,” in which he described his researches upon the geysers of the Yellowstone Park, and explained their action. -

Inrnorucrron the Mineral Roeblingite Has Been Reported from Two
MINERALOGICAL NOTES THE AMERICAN MINERALOGIST, VOL. 51, MARCH_APRIL' 1966 NEW DATA ON ROEBLINGITE1 FnaxrrrN F. Forr, !n., Department of Geology and Mineralogy, The IJniaersity of Michigan, Ann Arbor, Michigan- INrnorucrroN The mineral roeblingite has been reported from two Iocalities: Franklin was Furnace,New Jersey,and Langban, Sweden.The Franklin material frrst describedby Penfield and Foote (1897) as dense,white, compact massesof minute prismatic crystals associatedwith axinite, willemite, datolite, barite, arsenopyrite,sphalerite, titanite, rhodonite and rhodo- chrosite,in or near the limestone-granitecontact. During an extensive mineralogical investigation of the Langban mineralsinitiated in the late 1920'sby G. Aminoff of the Natural History Museum, Stockholm, Sweden, a mineral similar in composition to roeblingite was discovered. A complete investigation of this new dis- covery demanded more reliable chemical data than was offered by Penfieldand Foote.Therefore, R. Blix (1931)performed several chemical analyseson the Franklin roeblingite in an effort to remedy the difficulty encounteredby Penfield and Foote in assigninga chemical formula. The chemical analyses from both sources are tabulated in Table I. Strunz (1957) reports the Langban roeblingite as possibly being orthorhombic with o:8.3, b:13.1, and c:12'65 A. Ho*evet' some difficulty is en- countered in obtaining a reasonable formula from the application of theseparameters to the available chemical analyses. X-nav ANar-vsrs A specimenfrom each of the localities was investigated by both powder diffraction and single crystal methods. This investigation confirmed that roeblingite found at Langban is structurally identical to the Franklin material. A list of indexed d-values for roeblingite is presented in Table II. -

JOURNAL MINERALOGICALSOCIETY OF AMERICA 351 Missouri, of the U. S. Geological Survev. Starting out from Ilarrison, the main road running southwestward (in 1925 not completed, but ultimately to extend to Fort Smith) is followed' About 25 kilometers (16 miles) frorn Harrison the tiny settlement of Compton is passed,recognized by the right-angled turn of the road from south to west;and 6.5 km. (4 m.) further west,where the road swingssouthward, one's auto must be parked and the journey continued on foot. An indistinct road, used to haul out timber, extendseast from the main road down into the gorge of Sneed'sCreek (which rises somewhat further west than shown on the map) and this is to be followed about 200 meters, to a point where the slope becomes very steep. Then, on scrambling down the hillside perhaps 100 meters,a group of small prospectpits will be more or lessplainly seen. These have long since fallen shut, and good sized trees are growing on the dumps, but the light color of many of the frag- ments renders them rather conspicuous against the brown forest soil. On digging into the mass of decomposedshale-a pickaxe and spade will be found useful-occasional small lumps of a soft, white, chalky material, more or less stained by iron oxides, are encountered;and this is the newtonite. Under the microscopeit is seen to be made up of minute grains of nearly,squareoutline, which have been variously interpreted as rhombs or as tetragonal bipyramids, but which, it is hoped, can now be further studied. -

H Positions in Leucophoenicite, Mn7si3o12(OH)2: a Close Relative of the Hydrous B Phases
American Mineralogist, Volume 87, pages 154–159, 2002 H positions in leucophoenicite, Mn7Si3O12(OH)2: A close relative of the hydrous B phases MARK D. WELCH,1,* WILLIAM G. MARSHALL,2 NANCY L. ROSS,3 AND KEVIN S. KNIGHT2 1Department of Mineralogy, The Natural History Museum, Cromwell Road, London SW7 5BD, U.K. 2ISIS Facility, Rutherford Appleton Laboratory, Chilton, Didcot, Oxon OX11 0QX, U.K. 3Department of Geological Sciences, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061, U.S.A. ABSTRACT The proton positions in leucophoenicite, ideally Mn7Si3O12(OH)2, have been determined by neu- tron powder diffraction under ambient conditions on a natural sample from Franklin, New Jersey. 2 Refinement in the P21/a space group gave Rp = 2.0% (wRp = 2.1%), χ = 4.04 for 110 refined param- eters. The two non-equivalent protons form a pair of hydroxyl groups and make hydrogen bonds to the same O7 atom of the Si1 tetrahedron at distances of 1.99(1) and 2.09(1) Å. The H····H distance in leucophoenicite is 2.16(1) Å, which is more than twice the Van der Waal’s radius of H (>2 Å) and so no proton positional disorder is expected in leucophoenicite. A comparison of the H environments is made between leucophoenicite and Phase B, Superhydrous B, and Phase A. INTRODUCTION tions of cation octahedra in leucophoenicite are like those of Understanding the behavior of hydrogenous components of the hydrous sheet of Phase B.
