_Rubrical Query_ (Vol. vi., p. 509.).--QUÆSTOR inquires the meaning of the words "if occasion lie" in the Rubric immediately before the Offertory in the Communion Service. I am under the impression that "if occasion lie" here simply means, _in case there is necessity to do so_; and for the origin of this parenthetical clause I would refer to the Rubric of 1549 (Keeling, _Lit. Br._, edit. of 1842, p. 178.), which provides: "That in cathedral churches, or places where there is daily communion, it shall be sufficient to read this exhortation once in a month, and in parish churches on the week days it may be left unsaid." Showing clearly the mode in which the exhortation was intended to be used. The real difficulty, however, is not noticed by your querist, which is, as to when "Public warning of the Communion" is to be given. One Rubric says that this notice is to be given "immediately after the Nicene Creed;" another prescribes that when this warning is to be given, it shall be done "immediately after sermon." On this point see Sharpe on _Rubrics_, p. 62.; and Wheatly on _Common Prayer_, chap. vi. sect. viii. § 3. ENIVRI. _Rosa Mystica_ (Vol. vii., p. 182.).--I do not remember to have ever heard of such an institution; but _Rosa Mystica_ is one of the many appellatives of the Virgin Mary in the Roman Catholic "Litanies of the Virgin." C. _Portrait of Charles I._ (Vol. vii., p. 185.).--It may be confidently asserted that Vandyke never painted in enamel; the enamels referred to were at best only "after Vandyke." Nothing more frequent, in both earlier and present times, than the copying large oil portraits in enamel. C. "_Time and I_" (Vol. vii., p. 182.).--I cannot answer MR. BLACKISTON'S Query fully, but he will find, I think, in the miscellaneous correspondence usually printed in Pope's and Swift's works, the following anecdote, that some one having quoted to Robert, Lord Oxford, the adage, "Time and I 'gainst any two," his Lordship replied, impromptu, "Chance and I 'gainst Time and you." C. _The Word "Party"_ (Vol. vii., p. 177.).--I can furnish a more ancient example of the use of this word than the one given by your correspondent. In an old MS. "Booke of Recepts," in my possession, of the year 1681-2, there occurs the following singular prescription: "_The Powder of Buggs._--Take the buggs and wash them well in white wine, and putt them in a new earthen pott, and set them in an oven till they be dry enough for powder; then beat them, and sift them, and give ye party as much as will lye upon a groate every morning in honey." Can any one inform me for what disease this nauseous remedy was prescribed, and whether it be now excluded from the pharmacopoeia? Perhaps this oleaginous insect was formerly exhibited in those cases for which cod liver oil is now so extensively used. G.
