A highly interesting storehouse (once of great popularity, and now rare in all its editions) of a multitude of mathe- 

 matical, astronomical, and physical problems. It was based on the work of Bachet de Meziriac (v. Nos. 204 and 5901), 

 ante), and included, besides numerous original problems by the author, some taken from Cardan ; and in its turn formed 

 l^e foundation of the works of Mydorgue, Ozanam, Montucla, and Hutton. 



Among the more interesting problems are, in addition to the one mentioned above by M. Libri : ' How to make an 

 instrument that helpes to heare ' (the speaking tube, the invention of which is ascribed to Sir Samuel Morland in 1671), 

 ' a lami)e which goeth not out, though one carries it in one's pocket ', several magnetical problems, including ' a secrecie 

 in the Magnes, for discovering things farre remote ', ' of the Thermometer ', ' how to weigh the lightnesse of the ayre ',
