Excerpt from Columns: A Treatise on the Strength and Design of Compression Members III. Synthetical. Owing to the conditions now prevailing, it has been found impossible to get the complete work published, and in the present volume the historical portion, which consisted of a short summary of each important memoir, including all the published experimental work, has been replaced by a Bibliography. This Bibliography has been brought up to date, and includes, it is believed, all the more important original work on the subject. Articles of secondary interest and repetitions of work previously published have not been included. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
