Not a Brethren periodical exactly but there were many contributions by William Kelly and Samuel P. Tregelles.
"A medium of intercommunication between Christians on points of Biblical Criticism, Theological Science, Christian History, Biography, and Antiquarian research. This work is of the same size and general appearance as our old friend. Notes and (Queries, of which it is in fact an alter ego in a religioo domain. The first volume, in 374 pages,' contains twenty-eight numbers published in the course of 1854. The second volume, in 416 pages, contains thirty -one numbers published in the course of 1855. The third volume also comprises thirty-one numbers, extends to 518 pages, and appeared in 1856. A portion of vol. iv. is appended, containing the seven numbers which came out in 1857, and abruptly terminated the series in consequence of the unlooked-for decease of the excellent editor, Mr. L. H. J. Tonna." From: http://archive.org/stream/journalsacredli10cowpgoog/journalsacredli10cowpgoog_djvu.txt
Scans are available, also William Kelly's contributions can be read on STEM Publishing website.
Just 2 volumes published; the editor in later years left Brethren and went off doctrinally, embracing "non-eternity' views.
