_The Stature of Queen Elizabeth._--In a book entitled _Physico-Theology_, being the substance of sixteen sermons preached in St. Mary-le-Bone Church, London, at the Honourable Mr. Boyle's lectures in 1711 and 1712, with notes, &c., by the Rev. W. Derham (a _second edition_, with additions, published in 1714), the authors, in treating of the stature and size of man's body, says there is great reason to think the size of man was always the same from the Creation; and in a note at page 330., after quoting Dr. Hakewill's _Apolog._ and other authorities, concludes with these words:-- "Nay, besides all this probable, we have some more certain evidence. Augustus was five foot nine inches high, which was the just measure of our famous Queen Elizabeth, who exceeded his height two inches, if proper allowance be made for the difference between the Roman and our foot."--Vide Hakewill, _Apolog._, p. 215. Probably some of your learned correspondents may give additional information on this interesting subject. J. F. ALLEN. Macclesfield. _Portrait of Charles Mordaunt, Earl of Peterborough._--Can any of your readers inform me if there exists an original picture of Charles Mordaunt, the famous Earl of Peterborough, and where such can be seen? A TRAVELLER. _Inscription by Luther._--In looking at some of the old books in the library of the British Museum, I observed, on the fly-leaf of an old Bible, an inscription by Martin Luther, the meaning of which was the following:-- "Elijah the prophet said, the world had existed 2000 years before the law (from Adam to Moses); would exist 2000 years under the Mosaic dispensation (from Moses to Christ), and 2000 years under the Christian dispensation; and then the world would be burnt." The manuscript was in German and very much effaced, so that I am not able to remember the words, though I very well remember the meaning. Could any reader inform me in what part of the Bible this prophecy of Elijah's is to be found? for I have searched for it in vain. C. H. M. _"O Juvenis frustra," &c._--I should be glad to be informed, through your publication, where I may find this line,-- "O Juvenis frustra est tua Doctrina Plebs amat Remedia." J. W. V. _All-fours._--In Macaulay's essay on Southey's edition of _The Pilgrim's Progress_ (Longman & Co., p. 184.) occurs a curious use of this expression: "The types are often inconsistent with each other; and sometimes the allegorical disguise is altogether thrown off.... It is not easy to make a simile go on all-fours. But we believe that no human ingenuity could produce such a centipede as a long allegory in which the correspondence between the outward sign and the thing signified should be exactly preserved. Certainly no writer ancient or modern has achieved the adventure."
