The present bulletin represents work finished in the Division of Chemistry and Physics during the fiscal year 1888—'89, and resembles in general design and purpose its predecessors, Nos. 9, 27, 42, 55, and 60. It covers, however, only a part of the work actually accomplished, for some investigations are not yet completed, others will appear in special bulletins now in course of preparation, and many analyses will be published in forthcoming reports of the field geologists.

The present bulletin contains some of the more important results obtained in the chemical laboratory of the United States Geological Survey during the fiscal year 1884—'85. It also contains two physical papers representing work which was mainly done during previous fiscal years, but completed during the one for which this bulletin is issued. These papers are practically continuations of or supplements to Bulletin 14.
