Volume 10, Index

This index to volume l0 has again been prepared largely by D. L. I. cabri with the assistance of Dr. H. M. Aarden who prepared the entrles frr part g.'rne sfle b similar to that developed for volwne g with subject headings in Lold face type, and sub-headingsin italic"type. Authors'names appear in capitals. Bold face vpe-i; abo used tor new mineral names under "Geographical localities" as well as tmder the "mineral data" and "mineral occurrences". Suggestions for further imprwements in the index would be gratefully received.

THE CANADIAN MItgERAtOGtST is published by the Mineralogical fusociation of Canada. It continus the publication known widely as Contributions to Canadian Mineralogy which appeared as parts of the Geological series of the [Jniversifu of Toronto studies from 1g21 until the termination of the Studies in 1948, and as parts of The American Mineralogist from 1949 to 1955. The first number oI The Canadian Mineralogist, volume 6, part 1, was published in 1957. Manuscript papers in the fields of crystallography, geochemistry, mineralogy, petrology and allied sciences in either English or French, may be submitted to Professor L. G. Berry, Editoq Miller Hall, eueen,s IJniversity, Kingston, Ontariq at any time. The journal is issued twice a year and is sent to all members of the Mineralogical fusociation of Canada. The annual fee for ordinary and associate members is $7.00 ; for corporate members, including libraries $12.00; for student members 93.00. Membership in the fusociation is subject to the approval of the executive committee. Any person or institution, interated in advancing the aims and objects of the Association, are invited to apply for sustaining membership. Volumes 1, to 4: The issues appeared as "Contributions to Canadian Mineralogy," and were published as 26 non-consecutive numbers of the Geological series of the University of roronto Studies. Those numbers that are still available are for sale at $1.50 each from The Walker Mineralogical Club, 100 Queen's Park, Torontq Canada. The 26 issues that constitute volumes r to 4 may also be obtained on microfirm from the same address. volume 5 : The issues appeared as "contributions to canadian Min- eralogy" in the American Mineralogist The seven numbers, one per year from 1949 to 1955, were regular issues ol that publication, and wiil be found in library filc of that joumal. In 1957 The Mineralogical Association of canada commenced. publi- cation of rhe canadian Mineralogisr with volume 6, parr l. All back issues are available from the secretary of the Association, and are priced at $5.00 each for individuals, and $7.00 each for institutions. All inquiries regarding memberchip, noticq of change of address, and remittances should kre sent to Secretary, Mineralogical fusociation of Canada, c/o Mines Branch, 555 Booth Street, Ottawa 4, Canad,a.
