Samuel that he has been able to avoid all such difficulties by the use of a suitable birational transformation. c Weil, A., Colloque d'Algabre et ThUorie des Nombres, Centre Nat. de la Rech. Scient., Paris, 1950, pp. 125-127. I have been informed by T. Matsusaka, and also by A; N&on and P. Samuel, that they have independently developed theories of the Picard varieties. By means of the device referred to in footnote 4, Nron and Samuel have been able to derive the basic results on the existence of the Picard variety from the most elementary form of the criterion of the first kind.
