_Harvey and the Circulation of the Blood_ (Vol. ii., p. 266.).--The claim set up on behalf of Father Paul to the honour of Harvey's discovery, which is noticed by your correspondent W.W.B., is satisfactorily disposed of in the life of Harvey in the _Biographia Britannica_, iv. 2548., note C. Harvey gave a copy of his treatise _De Motu Cordis_ to the Venetian ambassador in England. On his return home the ambassador lent the book to Father Paul, who made some extracts from it. After Father Paul's death, he was thought to be the author of these extracts and hence the story which your correspondent quotes. It might occasionally be convenient if your correspondents could make _a little_ inquiry before they send off their letters to you. Beruchino. * * * * * MISCELLANEOUS. NOTES ON BOOKS, SALES, CATALOGUES, ETC. All who love the shady side of Pall Mall, and agree with Dr. Johnson that the tide of human enjoyment flows higher at Charing Cross than in any other part of the globe, will gladly welcome Mr. Jesse's recently published volumes entitled _London and its Celebrities_. They are pleasant, gossiping and suggestive, and as the reader turns over page after page of the historical recollections and personal anecdotes which are associated with the various localities described by Mr. Jesse, he will doubtless be well content to trust the accuracy of a guide whom he finds so fluent and so intelligent, and approve rather than lament the absence of those references to original authorities which are looked for in graver histories. The work is written after the style of Saint Foix' _Rues de Paris_, which Walpole once intended to imitate; and is executed with a tact which will no doubt render it very acceptable to those for whom it has been written, namely those persons whose avocations of business or pleasure lead them to traverse the thoroughfares of the great metropolis; and to whom it points out in a manner which we have correctly designated gossiping, pleasant, and suggestive, "such sites and edifices as have been rendered classical by the romantic or literary associations of past times." Messrs. Williams and Norgate have forwarded to us a Catalog of an extensive Collection of Books, the property of a distinguished physician, which are to be sold by auction in Berlin on the 21st of October. The library, which was forty years in forming, is remarkable for containing, besides numerous rare works in Spanish, Italian, French, and English Literature, a curious series of works connected with the American aborigines; and a most extensive collection of works on the subjects of Prison Discipline, Poor Laws, and those other great social questions which are now exciting such universal attention.
