Minerals from York, Pa. M. L. Jandorf. The writer recently found in a local limestone quarry the following minerals, unusual for this region: barite, in colorless, pale greenish, golden wine-yellow, and white crystals; minute pyrite crystals in perfect cubes and modified, the latter type encrusting crystals of barite; deep purple fluorite; and transparent calcite crystals a few mm, in diameter, of almost perfect rhombohedral form. Unfortunately the number of specimens obtained is insufficient to permit them to be offered in exchange.

An apparatus for growing large crystals has recently been patented by Dr. Otto Dreibrodt, of Bitterfeld, Germany (U. S. Pat. 1,353,571, Sept. 21, 1920). The plan consists in circulating the liquid past the suspended growing crystal, and cooling the liquid on its way into the crystallizing vessel.

The thirty-ninth regular meeting of the NEWARK MINERALOGICAL SOCIETY was called to order by Pres. Walther, with 11 members present, also 7 members of the New York Mineralogical Club, who had been invited to attend in a body. After the regular routine of business, Mr. Headley read a paper on "The More Unusual Minerals of N. J." Hydrophane, apatite, barite, opal, hyalite, and galenite were reported from Jersey City; sphalerite from Snake Hill; siderite, chalcopyrite, microcline, byssolite, gold, azurite, malachite, cuprite, native lead and silver were also mentioned.
Mr. Walther then read a paper on "Chemistry in Relation to Mineralogy" in which he said that most collectors did not know the symbols of the chemical elements, and advised such to study up on this matter. Proposals for membership were made by the secretary of Mr. J. A. Grenzig, of Brooklyn, and Mr. O. I. Lee, of Newark.

REPORT ON THE DISCOVERY OF DIAMONDS AT ABOMOSA, NORTHWEST (OF KIBBI, EASTERN PROVINCE, GOLD COAST. A. E. Kitson Govt. Press, Accra, Gold Coast, 1919; thru Min. Abstr., 1, 16, 1.920.
Small diamonds were found in Feb,, 1919 in the gravels of the Abomo Su and the neighboring streams. 175 stones weighed 4-13/32 carats, the largest 1/8 carat,. Good crystals showing octahedron and dodecahedron were observed. The gravels contain also topaz, zircon, black sand, garnet, corundum, rutile, and tourmaline in addition to quartz. The association suggests a granite pegmatite origin.{ DVB - well they missed that one - should be kimberlite}

THE ALA VALLEY AND ITS MINERALS. EMILIO REPOSSI.. Riv. Sci. Nat. "Natura," Pavia, 10, 89-132, 1919; thru Min. Abstr., 1, 13, 1920.
A detailed description of 11 localities in this region renowned for its wealth of minerals. The minerals occur in bands in the serpentine and include garnet, vesuvianite, diopside, epidote, apatite, clinochlore, magnetite, olivine and titanolivine, albite, prehnite, sphene, etc. Copper, cobalt and nickel minerals have been found in the mountains south of the Valley.

LAKE OF THE VOLCANO SHIRANE, KOZUKE, JAPAN. R. Ohashi .J. Akita Mining Coll., No. 1, 1-10, 1919.
Hollow spherical bodies of S float on the surface of the boiling crater-lake, while grains and vertical tubes of S are found in the mud at the bottom. Ascending H2S hissing thru molten S below the mud is believed to explain these occurrences. Three types of S are represented by this volcano, (1) pneumatolytic, around solfataras and in the fissures, (2) hydatogene, as beds of flour-sulfur in the crater lakes, and (3) from fusion, at the bottom of the
crater lakes. W. F. H.

NEW YORK MINERALOGICAL CLUB Regular Monthly Meeting of Wednesday, March 16, 1921

The regular monthly meeting of the New York Mineralogical Club was held in the Academy Room of the American Museum of Natural History on the evening of March 16th, at 8.15 P.M. The President, Dr. George F, Kunz presided and there was an attendance of 72 members and visitors. The minutes of the last meeting were read and approved. Mr. O. I. Lee showed a specimen of lava from Mt. Erebus collected on the Shackleton Expedition, also a specimen of granite collected 415 miles from the South Pole (Beardmore Glacier).

Mr. Radu then spoke on "The Luminescence of Minerals." He explained the nature of the light waves used and the meaning of the expression mm (millionth of a millimeter). He showed on the black board the wave-lengths of the principal rays used and explained the effect on certain minerals of vibrations produced by rays outside the spectrum. He then took up the subjects of fluorescence, phosphorescence and radioactivity, giving a short history of fluorescence and phosphorescence. The room being darkened, these effects were demonstrated in a very striking manner by means of apparatus which had been set up. Fluorescence produced by heat on pectolite was shown. Phosphorescence was produced in fluorite (chlorophane), willemite and troostite in calcite.

Dr. Kunz being called upon by the speaker showed a remarkable example of a phosphorescent diamond. Capt. Miller then exhibited these phenomena in thin sections of various minerals, by means of a specially equipped microscope which brought out many very striking effects.

A vote of thanks was tendered to Mr. Radu and to Capt. Miller.

Academy of Natural Sciences of Philadelphia, June 9, 1921

The June meeting of the Philadelphia Mineralogical Society was held on the above date, Dr. Hawkins presiding. Fourteen members and three visitors were present. Upon recommendation by the Council, Dr. L. C. Wills was elected to active membership.

Thru the courtesy of Dr. F. G. Kneer of New York, Dr. Hawkins was able to show a collection of 125 lantern slides of choice mineral specimens, which were extremely well colored, and strikingly realistic. Many groups in the Bement collection were included, those of calcite, quartz, malachite, azurite, tourmaline and fluorite being particularly noteworthy.

Mr. Biernbaum reported a three-day trip with Messrs. Frankenfield, Trudell, and Wills, to Falls of French Creek, the Birdsboro trap quarry, and Phoenixville, which resulted in turning up excellent chalcopyrite crystals at French Creek. Dr. Hawkins and Mr. Knabe reported sallies to Paterson, N. J., and O'Neills quarry, Pa., respectively, with negative results.

Minutes of the Regular Monthly Meetings of February, March, April and May.
On the afternoon of February 5th, Mr. Wm. H. Broadwell read a paper on "Mercury." A complete history of this metal was presented covering nomenclature, age, common and rare mineral species containing mercury, uses, (and abuses), etc. All the various mineral species were exhibited. Mr. Broadwell also made the statement that as high as 50 per cent of mercury is being recovered from scrap rubber.
     At the March meeting twenty-four members were present. The committee on the New Jersey State list of minerals advised that this work be postponed. Mr. Broadwell reported upon and had on exhibition the latest new mineral from Franklin, calcium-larsenite. He stated that this mineral showed a bright canary yellow fluorescence under the iron arc, quite distinctive from that of willemite.
     The April meeting was held on March 29th at Columbia University, New York City, in order to view the Eggleston collection of minerals. Dr. Blank of Columbia University spoke on "Some Applications of the Polarizing Microscope as Applied to the Identification of Minerals." At the close of the address the members examined many specimens under microscopes, illustrating the various points brought out in the address.
     The May meeting, the last indoor meeting until October, opened with an attendance of twenty-one members. Several reports were given. The Outing Committee reported that a field trip would be arranged for some Sunday in May. Mr. J. G. Manchester then gave a lecture on "The Artistry of Minerals." This was illustrated by means of one-hundred colored lantern slides.
Wm. H. BROADWELL, Secretary
