I have disposed of several copies 8vo of Laplace’s Systeme du monde, the only one I can procure, now, is a 4to sewed, 456 pages; Paris 1813, for $6= I don’t send it for fear it might not meet your Approbation, as you order a copy 8vo—if, for want of an 8vo, this 4to can suit your purpose, be so good to let me know it immediately, lest the Bookseller should part with the Book.—
