"Quia tres sunt qui testimonium dant, spiritus, et aqua, et sanguis, et tres unum sunt. Sicut in coelo tres sunt, Pater, Verbum, et Spiritus, et tres unum sunt." You will remember that it is quoted by Porson in his _Letters to Travis_, p. 148., and again referred to by him, pp. 394. 400. Was it sold on the death of the Bishop of Lichfield, or bequeathed to any public institution? or did it find its way into the possession of the Duke of Sussex, who was curious in biblical matters, and was a correspondent of Dr. Butler? Some of your learned readers will perhaps enable you to trace it. O.T. DOBBIN, LL.D. T.C.D. Hull, Yorkshire, Jan. 1851. _Merrick and Tattersall._--Will any of your correspondents be so obliging as to give the years of _birth_ of Merrick, the poet and versifier of the Psalms, and of his biographer, Tattersall. The years of their _deaths_ are given respectively 1769 {61} and 1829: but I can nowhere find when they were born. M. [Merrick was born in 1720, and Tattersall in 1752.] _Dr. Trusler's Memoirs._--I have the First Part of the _Memoirs of the Life of the Rev. Dr. Trusler, with his Opinions and Remarks through a Long Life on Men and Manners, written by himself._ Bath. Printed and published by John Browne, George Street, 1806. This Part is a 4to. of 200 pages, and is full of curious anecdotes of the time. It was intended to form three or more Parts. Was it ever completed: and if so, where to be procured? In all my searches after books, I never met but with this copy. At the end of the First Part there is a prospectus of a work Trusler intended to publish in the form of a Dictionary (and of which he gives a specimen sheet), entitled _Sententiae Variorum_. Can any of your Bath friends say if the manuscript is still in existence, as he states that it is ready for the press; or that he would treat with any party disposed to buy the copyright? T. _Life of Bishop Frampton._--I have in my possession a manuscript life of Bishop Frampton, who was ejected for not taking the oaths to William and Mary. It is of sufficient detail and interest to deserve publication. But before I give it to the world, that I may do what justice I can to the memory of so excellent a man, I should be happy to receive the contributions of any of your readers who may happen to possess any thing of interest relating to him. I have reason to believe that several of his sermons, the texts of which are given in his life, are still in existence. Will you be kind enough to allow your periodical to be the vehicle of this invitation? T. SIMPSON EVANS. Shoreditch. _Probabilism._--Will any one inform me by whom the doctrine of Probabilism was first propounded as a system? And whether, when fairly stated, it is any thing more than the enunciation of a deep moral principle? R.P.
