About This Book

A practical manual introduces atmospheric principles and explains how air pressure varies, then shows methods for using barometric measurements to determine altitude. It describes the design and mechanics of aneroid instruments, gives guidance on selecting and operating them, and provides worked examples and systematic procedures for field measurements. The book includes supporting reference tables—altitude conversions, logarithms, metric tables, corrections for mercurial instruments, and boiling-point correspondences—and offers advice on instrument care and interpretation of readings for both meteorological and surveying purposes.

PREFACE TO SECOND EDITION.

The fact that the first edition of this little manual is entirely exhausted is a sufficient indication that it supplied a want. As the use of the Aneroid Barometer is on the increase, the presumption is that there will be a further demand for this book of tables and instructions.

It has been thought advisable to rearrange the matter and to increase it by fuller descriptions of different instruments; and what is of more importance to the novice in measuring altitudes, to add a number of examples.

Another table has also been added to the collection of the previous edition.
