Excerpt from Journal of the Franklin Institute of the State of Pennsylvania and American Repertory of Mechanical and Physical Science, Civil Engineering, the Arts and Manufacturers, and of American and Other Patented Inventions, Vol. 35: January, 1843 N o're. - The intimate bearing of this investigation on the dimensions of abutments of bridges, locks, wharves, and all other structures in masonry which have to sustain an earthen embank ment, makes it as interesting to the civil as to the military engineer; therefore, I have thought it would not be unacceptable to the readers of the J ournal of the Franklin Institute. The analysis is as beautiful and concise as the complicated nature of the problem would allow. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
