_Arms in Dugdale's "Warwickshire," &c._--In Dugdale's _Warwickshire_ (1656), p. 733. fig. 21., is a coat of arms from the Prior's Lodgings at Maxstoke, viz. Or, fretty of ten pieces sa. with a canton gu. And in Shaw's _Hist. of Staffordshire_, vol. i. p. *210., is the notice of a similar coat from Armitage Church, near Rugeley, extracted out of _Church Notes_, by Wyrley the herald, taken about 1597: viz. "Rugeley as before, impaling O. fretty of ... S. with a canton G. Query if ..." Dugdale gives another coat, p. 111. fig. 12., from the windows of Trinity Church, Coventry; viz. Arg. on a chev. sa. three _stars_ of the first. There is a mitre over this coat. Can any of the correspondents of "N. & Q." assign the family names to these arms? Does the mitre necessarily imply a bishop or mitred abbot; and, if not, does it belong to John de Ruggeley, who was Abbot of Merevale (not far from Coventry) temp. Hen. VI., one branch of whose family bore--Arg. on a chev. sa. three _mullets_ of the first. I may observe that this John was perhaps otherwise connected with Coventry; for Edith, widow of Nicholas de Ruggeley, his brother, left a legacy, says Dugd., p. 129., to an anchorite mured up at Stivichall Church, a member of St. Michael's Church, Coventry. The same coat (_i. e._ with the mullets) is assigned by Dugd., p. 661. fig. 12., to the name of Knell. J. W. S. R. _Tombstone in Churchyard._--Does any one know of a legible inscription older than 1601? A. C. _Argot and Slang._--I shall be much obliged by learning from any correspondent the etymons of _argot_ (French) and _slang_, as applied to language; and when did the latter term first come into use?
