In my former note, it was shown that the father and mother of Sir Philip Wentworth were married before June, 1423; that Sir Philip was born circa 1424, and married in 1447; and that his eldest son, Henry Wentworth, being thirty years of age at his grandmother's death in 1478, must have been born circa 1448. It is therefore clear, that if his wife, Mary de Clifford, were a daughter of the fifth Lord Clifford, she could not have been less than thirty-five years older than her husband, and sixty years old when her eldest son was born. On the other supposition, she may have been about the same age with her husband, or perhaps two or three years only his senior. Can there then be any longer a doubt that this is a mistake of Dugdale? The other eminent genealogists, cited by your correspondent, have adopted the statement without farther investigation and upon no better authority, and the error has thus become familiarised by constant repetition. Had the misrepresentation been set right in the first instance, your readers would have been spared the infliction of this lengthy confutation, Miss Strickland herself protected from the humiliation of a defeat, "in daring to dispute a pedigree with King Henry VIII.;" and some of the numerous living descendants of the Protector Somerset been saved from much concern at finding a pedigree demolished, through which they had been wont to cherish the harmless vanity of being allied to the honour of a royal lineage. W. H. * * * * * PHOTOGRAPHIC CORRESPONDENCE. _Three New Processes by Mr. Lyte._--Will you kindly allow me room in your pages for the insertion of the following three processes, which may not, perhaps, be uninteresting to some of your readers? The first is respecting a very excellent combination with which to excite collodion. The second is on the subject of a capital developing agent, and, I believe, a partially new one. The third, a certain improvement in the production of positives on albumen paper. To make my collodion, I use the Swedish filtering paper, as recommended by the Count de Montizon, Mr. Crookes, &c., not so much on account of its superior properties, as the easier manipulation, and the greater certainty of obtaining a completely soluble substance. Having obtained a clear and tolerably thick collodion, take Rectified spirits of wine 1 oz. Iodide of ammonium 45 grs. Bromide of ammonium 12 grs. Chloride of ammonium 1 gr. Iodide of silver, freshly precipitated from the ammoniated nitrate, as much as the solution thus produced will take up--a small excess, which will settle at the bottom, will not signify. Nearly the same compound, one which is equally good, is produced as follows. Take Rectified spirits of wine 1 oz. Iodide of ammonium 50 grs. Bromide of ammonium 12 grs. Chloride of silver 5 grs.
