It is to be hoped that the time in which such a threat could be executed has passed by, and that no danger need now be apprehended by the possessor for his open avowal of the facts of the case, such as they are. Indeed, it seems desirable that if fair means could lead to such a result, the skull of one who filled so conspicuous a position amongst England's most distinguished rulers, should become public property. Perhaps some one in possession of the arguments verifying the identity of the skull in question with that of Cromwell, would, by a recapitulation of them, favour some readers of the "N. & Q.", and amongst others J. P. Dudley. _Guy, Thomas, Founder of Guy's Hospital, and M.P. for the Borough of Tamworth, d. s. p. 1724._--Can any of your readers give information as to the existence of any member of this family in the male line? The senior line of descent from Guy's maternal uncle, John Voughton, became extinct in 1843 upon the decease of Elizabeth, the relict of Dr. Clarke of Weggington, brother of Sir Charles M. Clarke, Bart. KT. _Episcopal Mitre_ (Vol. iii., p. 62. _et seq._).--In addition to this Query, which has elicited much to interest one, I beg to know at what _date_ and _why_ the use of the mitre in England was discontinued? At the coronation of George IV. I, for one, was grievously disappointed not to see the whole bench of bishops _mitred_ as well as _robed_. S. S. _John Lord Berkeley, Bishop of Ely._--In the Diary of Dr. Edward Lake, published in the _Camden Miscellany_, vol. i. p. 16., occur the following paragraphs:-- "Dec. 23. 1677. I administered the sacrament to the Lord John Barclay, being not well." To the word Barclay, the editor, George Percy Elliott, Esq., has subjoined the following note:-- "Probably Lord John Berkeley; he was afterwards Bishop of Rochester, and subsequently of Ely, and was deprived for not taking the oath of allegiance to William and Mary." Can any reader of "N. & Q." suggest any authority for the statement in the editor's note? Francis Turner was Bishop of Ely from 1684 to 1691, when he was deprived for refusing to take the oath of allegiance to William and Mary. Turner was succeeded by Simon Patrick, translated from Chichester. As to the Rochester see, that was filled by Thomas Sprat from 1684 to 1713. His biography reminds one more of the Vicar of Bray than the sturdy Nonjuror. J. Y. Hoxton. _Palace of Lucifer._--In Milton's elegy upon the death of Bishop Andrewes there is an allusion to a fabled _Palace of Lucifer_ which I do not quite understand. It seems to refer to some romantic description or other, and I shall be much obliged to any one that will kindly tell me by whom. It is always important to know something of the train of an author's reading, as we then can better understand the ordinary train of his thoughts--
