_Arago on the Weather._--I saw some of Arago's meteorological observations in an English magazine some time ago, taken, I believe, from the _Annuaire_. Can any one give me a reference to them? ELSNO. _"Les Veus du Hairon," or "Le Voeu du Héron."_--Is any more known of this curious historical romance than Sainte Palaye tells us in the third volume of his _Mémoires sur l'Ancienne Chevalerie_? He gives the original text (I suspect not very correctly) from, he says, a MS. in the public library at Berne. It is a poem in old French verse (something like Chaucer's English), of about 500 lines, descriptive of a series of _vows_, by which Robert Comte d'Artois, then an exile in England, engaged Edward III., his queen and court, to the invasion of France: "Dont maint bon chevalier fu jété fort souvin; Mainte dame fu vesve, et maint povre orfelin; Et maint bon maronier accourchit son termin; Et mainte preude femme mise à divers destin; Et encore sera, si Jhesus n'i met fin." The first lines of the poem give the place and date of the transaction, "London, September, 1338," in King Edward's "palais marbrin." The versification is as strange as the matter. The author has taken great pains to collect as many words rhyming together as possible. The first twenty-six lines rhyme to "in;" the hundred next to "is;" then fifty to "ent," and so on: but the lines have all their rhythm, and some are smooth and harmonious. Has any other MS. been discovered? Has it been elsewhere printed? Has it been translated into English, or has any English author noticed it? If these questions are answered in the negative, I would suggest that the Camden, or some such society, would do well to reprint it, with a translation, and Sainte Palaye's commentary, and whatever additional information can be gathered about it; for although it evidently is a _romance_, it contains many particulars of the court of England, and of the manners of the time, which are extremely curious, and which must have a good deal of truth mixed up with the chivalrous fable. C. _Inscriptions on a Dagger-case._--I have in my possession a small dagger-case, very beautifully carved in box-wood, bearing the following inscriptions on two narrow sides, and carved representations of Scripture subjects on the other two broad sides. _Inscriptions._ "DIE EEN PENINCK WINT ENDE BEHOVT DIE MACHT VERTEREN ALS HI WORT OWT HAD." "ICK DAT BEDOCHT IN MIN IONGE DAGEN SO DORST ICK HET IN MIN OVTHEIT NIET BEGLAGEN."
