THE AMERICAN MINERALOGIST. VOL, 55. NOVEMtsER.DECEMBER. 1970 INDEX TO VOLUME 55, 1970 The index for this volume attempts to combine the advantages of the content of the traditional subject index, with the computer storage and retrieval possibilities of the KWIC index that was used for volumes 52-54. This index is processed and printed from the input to the Bibli.ography and Iniler oJ Geology,under a contract arrangement with the American Geological Institute. Thanks are due them for their excellent cooperation in this initial venture. The content and layout of this index, and in particular the choice of sub- ject headings, and subheadings, is still evolving. General cornments and specific suggestions from users will be welcomed, and should be addressed to the Editor oI The American Mineralogisl. 2147 AUTHOR INDEX TO VOLUME 55 7-8 1440 Adams. John W.
