To introduce Clouds (Vol. viii., p. 451.) as desired by your correspondent Σ., the negative must be treated in the sky by solution of cyanide of potassium laid on in the form desired with a camel's hair pencil. This discharges a portion of the reduced silver, and allows the light to penetrate; but great care is required to stop the action by well washing in water before the process has gone too far. White clouds are produced by painting them in with a black pigment mixed in size.

Death of Edward II. (Vol. viii., p. 387.).—P. C. S. S. has noticed with considerable surprise the very strange assertion of Mr. C. M. Ingleby with reference to the murder of Edward II. at Berkeley Castle, viz. that "Echard and Rapin are silent, both as to the event and the locality." If Mr. Ingleby will again refer to Echard (vol. i. p. 341., edit. 1718) and to Rapin (vol. iii. p. 147., edit. 1749), he will perceive that the two historians record "both the event and the locality."
Mr. Ingleby did not perhaps consider that the transaction in question took place during the reign of Edward III.; and is, therefore, not to be sought for at the close of that of Edward II. (where probably Mr. C. M. Ingleby looked for it), but among the occurrences in the time of Edward III. Mr. C. M. Ingleby will assuredly find it there, not only in Echard and Rapin, but in every other History of England since the date of the "event."

Luther no Iconoclast (Vol. viii., p. 335.).—An occasional contributor wishes the Editor to note down this Query. What could have led your correspondent J. G. Fitch to use so peculiarly inappropriate a synonym for Martin Luther as "the great Iconoclast?" Has he any historical evidence for Luther's breaking a single image?
It is not to defend Luther, but to point out a defect in his teaching, as it is regarded by the adherents of other Protestant churches, that Dr. Maclaine has said, in his note on Book IV. ch. i. § 18. of Mosheim:
