_Surname of Allen_ (Vol. vii., p. 205.).--Perhaps A. S. A. may find the following words in Celtic of use to him in his researches as to the origin of the name of Allan:--_Adlann_, pronounced _all[=a]nn_, means a spearman or lancer; _aluin_, a white hind or fawn (Query, Do any of the name bear a hind as a crest?); _allin_, a rocky islet; _alain_, fair, bright, fair-haired, &c. FRAS. CROSSLEY. _Belatucadrus_ (Vol. vii., p. 205.).--Papers concerning the god Belatucadrus are to be found in the _Archæologia_, vol. i. p. 310., vol. iii. p. 101., vol. x. p. 118. I take these references from Mr. Akerman's useful Archæological Index. C. W. G. _Pot-guns_ (Vol. vi., p. 612.; Vol. vii., p. 190.).--In the parish of Halvergate, a train of seventeen pot-guns is kept at the blacksmith's shop. MR. WOODWARD is correct in stating that they are "short cylinders set perpendicularly in a frame, flat-candlestickwise;" but each pot-gun at Halvergate is set in a separate block of wood, and not several in a frame together. By touching the touchholes of each pot-gun successively with a bar of red-hot iron, and with the aid of two double-barrel guns, a royal salute is fired at every wedding or festive occasion in Halvergate. E. G. R. _Graves Family_ (Vol. vii., p. 130.).--Your correspondent JAMES GRAVES will find a tolerable pedigree of the Graves family, commencing in the time of Edward IV., in the first volume of Dr. Nash's _Worcestershire_; and, in the notes thereto, many interesting particulars of various learned members of the family. Independent of the three portraits mentioned by your correspondent, of which I possess fine proof impressions, I have also one in mezzotinto of Morgan Graves, Esq., of Mickleton, county of Gloucester, and Lord of the Manor of Poden, in the co. of Worcester. J. B. WHITBORNE. _Portrait Painters_ (Vol. vii., p. 180.).--The name of the Derby artist was _Wright_, not _White_. I have seen several portraits by him of great excellence. The time of his death I do not recollect, but I think the greater part of his works were executed in the latter part of the last century. Have not some of them been exhibited in Pall Mall? I have not the means at hand of ascertaining the fact, but I think he painted the "Blacksmith's Forge," which was so admirably mezzotinted by Earlom. E. H. _Plum Pudding_ (Vol. vi., p. 604.).--Southey, in his _Omniana_, vol. i. p. 7., quotes the following receipt for English plum puddling, as given by the Chevalier d'Arvieux, who in 1658 made a voyage in an English forty-gun ship:
