_Discovery of the Circulation of the Blood_.--There is a passage in Longinus (ch. xxii.), familiar perhaps to some of the readers of the "NOTES AND QUERIES," which indicates that the fact of the circulation of the blood was well established in the days of Plato. The father of critics, to exemplify, and illustrate the use and value of _trope_ in writing, has garbled from the Timaeus, a number of sentences descriptive of the anatomy of the human body, where the circulation of the blood is pointed at in terms singularly graphic. The exact extent of professional knowledge arrived at in the time of the great philosopher is by no means clearly defined: he speaks of the fact, however, not with a view to prove what was contested or chimerical, but avails himself of it to figure out the surpassing wisdom of the gods in constructing the human frame. Perhaps some of the readers of the "NOTES," who are more thoroughly conversant with the subject, may think it worth while to inquire how much was known on that subject before Harvey wrote his _Exercitationes Anatomiae_. The _Prooemium_ of that author seems hardly sufficient to satisfy the desire of every reader, who has looked with some care to the passage in Longinus to which I have taken the liberty of calling public attention. A.W. Brighton. _The Meaning of "Pallace_."--A lease granted by the corporation of Totness in Devon, in the year 1703, demises premises by this description: "All that cellar and the chambers over the same, and the little _pallace_ and landing-place adjoining to the river Dart." Can your readers give an explanation of the term "pallace?" J.R. ROGERS. _Did Oliver Cromwell write "The New Star of the North?_"--Perhaps some of your numerous correspondents, who have perused a curious letter of Count de Tessins, in Clements' _Bibliothèque Curieuse_, tome ix. page 331., can inform me what credit, or if any, is due to the Count's conjecture, that Oliver Cromwell was the author of the book entitled _The New Star of the North, shining upon the victorious King of Sweden_, &c. 4to. London, 1632. J.M. Oxford. _Meaning of Savegard and Russells_.--In the will of Elizabeth Coddington, lady of the manor of Ixworth, 1571, mention is made of "the red _russells_ quilt," of "a felde bed," and of "my cloke and _savegard of freseadon_." I shall be obliged by any description of the garment known as the _savegard_, and of the _russells quilt_. BURIENSIS.
