Frankfurt am Main, Johann David Sauerländer, 1829. Cont. marbled boards. A paper-label pasted on front cover with handwritten title. Backstrip a little torn and with repairs. XII,189 pp. and 3 tables. Light yellowing to leaves.
Scarce first German edition of this principal contribution to The Theory of Numbers, and it is the first work at all to be devoted exclusively to this subject. It introduced the symbol "a/p", still used to express the law of reciprocity.
