So that although Mabillon says that scarce one in a thousand could address a _Latin_ letter to another, yet he by no means says that it was on account of their general ignorance, but because they were addicting themselves to other branches of learning. They were devoting all their energies to Arabic and Chaldæan science, and in their pursuit of it neglected other literature. A similar remark might be made of respecting many distinguished members of the University to which I belong; yet who would feel himself justified in inferring thence that Cambridge was sunk in ignorance? CANTAB. * * * * * ADVERSARIA [In our Prospectus we spoke of NOTES AND QUERIES becoming everybody's common-place book. The following very friendly letter from an unknown correspondent, G.J.K., urges us to carry out such an arrangement. "Sir,--I beg leave to forward you a contribution for your 'NOTES AND QUERIES,' a periodical which is, I conceive, likely to do a vast deal of good by bringing literary men of all shades of opinion into closer juxtaposition than they have hitherto been. "I would, however, suggest that in future numbers a space might be allotted for the reception of those articles (short of course), which students and literary men in general, transfer to their common-place books; such as notices of scarce or curious books, biographical or historical curiosities, remarks on ancient or obsolete customs, &c. &c. &c. Literary men are constantly meeting with such in the course of their reading, and how much better would it be if, instead of transferring them to a MS. book to be seen only by themselves, or perhaps a friend or two, they would forward them to a periodical, in which they might be enshrined in imperishable pica; to say nothing of the benefits such a course of proceeding would confer on those who might not have had the same facilities of gaining the information thus made public. "In pursuance of this suggestion, I have forwarded the inclosed paper, and should be happy, from time to time, to contribute such gleanings from old authors, &c. as I might think worth preserving. "G.J.K." We readily comply with G.J.K.'s suggestion, and print, as the first of the series, his interesting communication, entitled:] 1. _Writers of Notes on Fly-leaves, &c._
