_Derivation of Yankee_ (Vol. iii., p. 461.).--Washington Irving, in his _Knickerbocker's History of New York_, gives the same derivation of "Yankee" that is quoted from Dr. Turnbull and from Mr. Richmond. Irving's authority is, I believe, earlier than both these. Is the derivation his? and if his, is he in earnest in giving it? I ask this, not because I have reason to doubt in this instance either his seriousness or his philological accuracy, but by way of inserting a caution on behalf of the unwary. I have read or heard of a learned German who quoted that book as veritable history. The philology may be as baseless as the narrative. It is a happy suggestion of a derivation at all events, be it in jest or in earnest. E. J. S. _Ferrante Pallavicino_ (Vol. iii., pp. 478. 523.).--Your correspondent CHARLES O'SOULEY will find some account of Ferrante Pallavicino in Chalmers, or any other biographical dictionary; and a very complete one in the _Dictionnaire Historique_ of Prosper Marchand. The manuscript he possesses has been printed more than once; it first appeared in the _Opere Scelte di Ferrante Pallavicino_ printed at Geneva, but with the imprint Villafranca, 1660, 12mo., of which there are several reimpressions. It is there entitled _La Disgratia del Conte D'Olivares_, and bears the fictitious subscription of "Madrid li 28 Gennaro, 1643," at the end. If the MS. was written at Genoa, it is most probably only a transcript; for Pallavicino was resident at Venice when it appears to have been written, and was soon after trepanned by a vile caitiff named Charles de Bresche _alias_ De Morfu, a Frenchman employed by the Pope's nuncio Vitellio, into the power of those whom his writings had incensed, and was by them put to death at Avignon in 1644.
