¹ There is in the same library (Rés. x. 1, 791) another copy of Nonius (Paris, 1583, 8vo.), whose marginalia come from this volume. At the end stands this entry in the handwriting, I think, of P. Pithou the younger: ‘Emendavi Lutetiae ex libro v. cl. Claudii Puteani MDCXII kal. Mart.’ The fact that no less than three copies of the readings of so important a MS. should have remained undiscovered emphasises anew the necessity for catalogues of all those early editions of the Classics which are provided with marginalia. The Cambridge University Library has long had a printed catalogue of this kind; the Bodleian now possesses a written one. It is to be hoped that other libraries will follow their example.
