_The Milesians._--With respect to the origin of the Milesian race little seems to be known, even by antiquaries who have given their attention to the archaeology of Ireland, the inhabitants of which country are reputed to have been of Milesian origin. The Milesian race, also, is thought to have come over from Spain, a conjecture which is rather confirmed by the etymology of the names of some Irish towns, where the letters _gh_, as in Drogheda and Aghada, if so convertible, have the same pronunciation as the Spanish _j_ in Aranjuez and Badajoz, and also by the expression and cast of features marked in many of the peasants of the south-west of Ireland, which strikingly resemble those of the children of Spain. There is also another subject of antiquity in Ireland, and closely connected with her early history, of the true origin of which the world seems much in ignorance, viz. her Round Towers. Possibly some of your able correspondents will kindly supply some information on one or both of these subjects. W. R. M. _Round Robbin._--In Dr. Heylin's controversy with Fuller on his Church History, the following quotation[1] occurs: "That the Sacrament of the Altar is nothing else but a piece of bread, or a little _predie round robbin_." In the East Riding of Yorkshire the term is designative of a petition, in which all the names are signed radiating from a centre, so as to render it impossible to discover who was the first to sign it. What is the derivation of it? R. W. E. Cor. Chr. Coll., Cambridge. [Footnote 1: _Appeal of Injured Innocence_, p. 462.] _Experto crede Roberto._--What is the origin of this saying? N. B. _Captain Howe._-- Captain Howe, the King's (George II.) nephew by an illegitimate source."--_Pictorial History of England_, iv. 597. Can you inform me how this captain was thus related to George II.? F. B. RELTON. _Bactria._--Can you refer me to a work worthy the name of _The History of Bactria_, or to detached information concerning Bactriana, under the Scythian kings? I also want a guide to the Graeco-Bactrian series of coins. BLOWEN. * * * * * Replies. THE FAMILY OF THE TRADESCANTS. (Vol. ii., pp. 119. 286.)
