_Alexander Clark_ (Vol. vii., p. 580.).--I should feel obliged if J. O. could find leisure to communicate to "N. & Q." some particulars relative to Clark. He is supposed to have been the author of a curious poem: _The Institution and Progress of the Buttery College of Slains, in the Parish of Cruden, Aberdeenshire; with a Catalogue of the Books and MSS. in the Library of that University_: Aberdeen, 1700. Mr. Peter Buchan thus mentions him in his _Gleanings of Scarce Old Ballads_: "Clark, a drunken dominie at Slains, author of a poetical dialogue between the gardeners and tailors on the origin of their crafts, and a most curious Latin and English poem called the 'Buttery College of Slains,' which resembled much in language and style Drummond of Hawthornden's 'Polemo Middino.'" This poem is printed in Watson's _Collection of Scottish Poems_, Edin. 1711; and also noticed in the _Edinburgh Topographical and Antiquarian Magazine_, 1848, last page. I am anxious to ascertain if the emblem writer, and the burlesque poet, be one and the same person. The dates, I confess, are somewhat against this conclusion; but there may have been a previous edition of the _Emblematical Representation_ (1779). The _University_ Clark is supposed to have been an Aberdeenshire man. Possibly J. O. may be able to throw some light on the subject. PERTHENSIS. _Christ's Cross_ (Vol. iii., pp. 330. 465.).--In Morley's _Introduction to Practical Music_, originally printed in 1597, and which I quote from a reprint by William Randall, in 4to., in 1771, eighteen mortal pages (42-59), which, in my musical ignorance, I humbly confess to be wholly out of my line, are occupied with the "Cantus," "Tenor," and "Bassus," to the following words: "Christes Crosse be my speed in all vertue to proceede, A, b, c, d, e, f, g, h, i, k, l, m, n, o, p, q, r, s, & t, double w, v, x, with y, ezod, & per se, con per se, tittle tittle est Amen, When you haue done begin again, begin again." J. F. M. {19} _The Rebellious Prayer_ (Vol. vii., p. 286.).--J. A. may find the poem, of which he quotes the opening lines, in the _Churchman's Monthly Penny Magazine_, October, 1851, with the signature L. E. P. The magazine is published by Wertheim & Macintosh, 24. Paternoster Row. M. E. "_To the Lords of Convention_" (Vol. vii., p. 596.).--L. EVANS will find the whole of the ballad of "Bonnie Dundee," the first line of which he quotes, in Sir Walter Scott's _Doom of Devorgoil_, where it is introduced as a song. Singularly enough, his best ballad is thus found in his worst play. FICULNUS.
