185. Johannes Lychtenberger.

—The "Pronosticatio," or "prophecies," which bear this name, have been often reprinted since what I believe to be the first edition was published in the year 1488. In giving an account of the copies of it in the Lambeth Library, I stated that I knew of no other copy of this edition, except one in the Douce collection in the Bodleian. Eight years have elapsed since that time, and I have not heard of any; and as circumstances have lately led to my being engaged about the book, I shall be glad if you will allow me to ask whether any of your many learned correspondents know of a prior edition, or of any other copies of this one of 1488?

186. Lestourgeon the Horologist.

—I have in my possession an apparently very old, though very elegant and very excellent, eight-day clock, with the maker's name on its face, Thomas Lestourgeon, London. Some years ago there was found among the apparatus of the Natural Philosophy class, in the University of Edinburgh, what is called in the inventory "an old watch, maker's name Lestourgeon, London." Can any of your readers tell me when that excellent horologist flourished? I know the history of the clock for about a century, but how much older it may be I should like to know.

187. Physiological Query.

—Can any of your correspondents mention the work of any physiologist in which the cause is given why all herbivorous animals suck in what they drink, and all carnivorous animals lap it up by the action of the tongue? Also, what naturalists have specified that broad distinction, and whether it has been mentioned in any other work?
