Leonhardi Euleri Commentationes Arithmeticae Collectae, Dr. P. H. Fuss et Nicolaus Fuss. Tomus Prior & Tomus Posterior, Petropoli (St. Petersburg) - 1849 - 2 vols.,584 + 651 pp.,
It is bound in one large binder. I believe that this was done at the beginning
of the 20-th century (judging from an ad on the inside). Internally very clean set.
First edition of this collection of previously unpublished mathematical writings, mostly, but not exclusively, devoted to number theory (there are altogether 94 numbered treatises
and five further Additamenta ). "This edition (L. Euleri, Commentationes arithmeticae collectae, Petropoli, 1849) strongly influenced the further development of number theory
in the 19th century. Jacobi helped the publication by his counsel, and by gathering information on Euler's work at the Berlin Academy of Sciences. Immediately after the publication
of these two volumes of Euler's works, Jacobi and Dirichlet discovered many interesting facts in Euler's materials" (Kolmogorov & Yushkevich, Mathematics of the 19th Century:
Mathematical Logic Algebra Number Theory, p. 182). "It should be no surprise that a case could be made that Euler wrote, but never published, the first number theory textbook.
It was a little-known manuscript, 'Tractatus de numerorum doctrina capita sedecim quae supersunt', 'Tract on the doctrine of numbers', consisting of sixteen chapters. This is an
unfinished first draft of part of what Euler apparently planned to be a textbook on number theory. He certainly did not intend it to be published in this form, and it was only published in
1849 [in the present work, Vol. II, pp. 503-575], 66 years after his death . . . From the titles of the chapters, it appears that Euler's major interest in starting to write this book is to study
the prime divisors of certain binary forms" (Sandifer, How Euler did it - THe Euler Archive, November 2006). "In part [the Tractatus] looks like a first draft for sections I, II and III of
Gauss's Disquisitiones Arithmeticae" (Weil, Number Theory: An Approach through History, p. 192). Two vols in 1
vol 1 584, vol 2: 651 pages
