Excerpt from Annual Report of the Chief Signal Officer to the Secretary of War Arranged in the Form of a Text-Book Designed, for Use in the Signal Service School of Instruction at Fort, 1886, Vol. 2 of 2The Object of the following work has been to Select from the material on hand some of the more important principles, methods, and results arrived at, mostly during the last quarter Of a century, and to present them in the form of a text-book of the higher meteorology, supplement ary to more elementary works, for use in the meteorological work of the Signal Service. The subject, however, has become now so vast, embracing so many things of very great interest and importance, that justice cannot be done to it in one volume of moderate size. Much, therefore, of great interest is necessarily either excluded entirely or only brie¿y referred to. This has especially been done in the case of papers which are well known and accessible. No space could be given to a description and explanation Of the many recent inventions and improve men ts in meteorological instruments for making and recording observa tions. If the work seems therefore defective it is hoped that the omissions will be found to be in some measure supplied by the numer ous references through the work to books and papers from which, in general, further details can be obtained, and likewise much additional and useful matter on the subject under consideration.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
