Oxford. 326. _Latin Verse on Franklin._--Can you inform me who wrote the line on Franklin: "Eripuit coelo fulmen, sceptrumque Tyrannis?" HENRY H. BREEN. St. Lucia. 327. _General Moyle._--Who was General John Moyle, who died about 1738? He resided, if he did not die, in Bury St. Edmund's, Suffolk. BURIENSIS. 328. _Musical Compositions of Matthew Dubourg._--I am induced, while preparing for the press a new edition of my _opusculum_ on the _violin_, to seek your kind mediatorial aid in behalf of an object which some one or other of your correspondents, acquainted with Irish matters of the last century, may _possibly_ enable me to attain. I am desirous of learning whether there be _extant_ any of the musical compositions (especially the violin _solos_ and _concertos_) of my progenitor, Matthew Dubourg, who held the post of director and composer to the king's band in Ireland, from 1728 until, I believe, his death in 1767. As I do not know that any of these compositions (which appear to have been called forth by immediate occasions) were ever _printed_, my hope of now tracing them out is perhaps more lively than rational. If they have existed only in a manuscript state, it is but too possible that the barbarian gripe of the butterman may long ago have suppressed what vitality was in them. I cannot, however, relinquish the idea that a dusty oblivion, and not absolute destruction, may be the amount of what they have undergone; and that they _may_ still exist in such condition as to be, at least, more susceptible of resuscitation than disinterred _mummies_. I have the honour to be, Sir, yours wistfully, G. DUBOURG. Brighton. 329. _Collodion, and its Application to Photography._--May I ask for information as to the first discoverer of Collodion, and the origin or derivation of the name? I should also be glad to know by whom it was first applied to photogenic purposes. A PHOTOGRAPHER. 330. _Engraved Portrait._--Will some of your correspondents who are conversant with the history of engraved English heads, oblige me by naming the original of a copper-plate print in my possession, and also with the conclusion of the verses beneath, the lower part of the plate being mutilated. The verses, as far as I have them, run thus: "Here you may see an honest face, Arm'd against envy and disgrace; Who lives respected still in spite . . . . . . . . ." The addition of the names of the painter and engraver will increase the obligation. HENRY CAMPKIN. 331. _Lines by Lord Chesterfield on Queen Caroline's supposed Refusal to forgive her Son when on her Death-bed._--In Coxe's _Life of Sir Robert Walpole_ (vol. i. p. 549.), we read, in the account of the death of Queen Caroline, as follows:
