A report about the characteristics of a few Oligocene insects of different orders which, from some peculiarity, have been thought worthy of special study out of serial course.

Report describing work done in the division of chemistry and physics during the fiscal year of 1891. It includes summaries with findings for much of the research.

A report about certain researches on the thermodynamics of liquids in progress at the laboratory.

A report about about the viscosity of solids which have an immediate bearing on the molecular mechanism by which viscous motion in solids is promoted.

A paper which records all of the shocks observed or felt on Mount Hamilton, and all of those reported to the Lick Observatory by letter; as well as newspaper reports of such earthquakes as occurred in the state during that year.

From outline: The aim of this paper is to review the progress of our knowledge concerning a well defined system of rocks on'the Atlantic border, named the Newark system; to summarize the present state of information concerning it, and to discuss the bearing that its study has on principles of correlation.

From preface: In the following chapters, I have commenced a serious study of the volume thermodynamics of liquids and solids. The work is, as yet, confined to volume, pressure, and temperature. Questions involving entropy and energy are also in active progress, but can not be included in the present bulletin.

From outline: This hook is a review of the present state of knowledge of the general structure of the pre-Cambrian rocks of the United States and Canada. The material contained in the historical chapters is of two kinds: Summaries of all articles pertaining to the subject considered, and summaries of the conclusions which appear to be established. The first represents the substance of the literature; the second brings together the important ascertained structural facts, and often times becomes a more or less extended discussion. The final chapter covers the same grounds as the historical chapters for the various pre-Cambrian in general successions proposed by different authors, and also contains a discussion of results and the principles upon which they are based. Within the chapters, individual districts or regions are given separate sections, and the summary of literature for each is arranged in chronological order.

From outline: This paper, after discussing general principles connected with the study and description of the Tertiary or Cenozoic rocks and fossils contained in them, takes up the Neocene deposits of the United States in particular. A chapter is devoted to a summary of what is known in regard to the Neocene of the eastern coast of the United States, each State in geographical order being separately considered, beginning at the north.
