Excerpt from Contributions to Barometric Hypsometry: With Tables for Use in California Having been, for more than twenty-five years, almost constantly employed in geological surveys of our Western States, I have had occasion to use the barometer quite extensively as a hypsometrical instrument. As early as 1847, being engaged in determining the height of points along the south shore of Lake Superior, I became convinced that there were sources of error in our barometrical work which had not been sufficiently taken into account; and by repeated measurements of a number of elevations at different seasons and hours, I arrived at the conclusion that our results were always lower in cold weather, or at morning and evening, than they were in warmer weather or towards noon. I or some years after this my field of labor was among the prairies of the Mississippi Valley, where there was little occasion for hypsometrical work, and the subject of the uncertainties and perplexities of barometrical determinations of heights was for a time dismissed from my thoughts. Later, however, on taking charge of the Geological Survey of California, where the barometer became again an instrument of the greatest importance, and indeed an indispensable companion in our field-work, the same difficulties which had been met with on Lake Superior ban again to be noticed, and to call for investigation.
