 diminutionis compiled by Abraham, supposed to be Aben Ezra (/.I pp. 304-76), Account of an extract from the Liber 

 Abbaci of Leonard ot Pisa (v. II pp. 287-304), the Practica Geometric/*, of the same author, being the whole of his algebra 

 (v. II pp. 305-76), and extracts from Pacioli (v. Ill pp. i77-94,\ besides many other matters not relating to arithmetic.' 

 Prof, de Morgan's Arithmetical BooAx 



As was remarked in the first division of the Biblio'.heca Chemico-Mathematica, it is very sad that a mathematician

 sciences to the wholesale depredation of public libraries for a long period of years !

The author seriously maintains that the lamps of the Vestal Virgins were inextinguishable, and continued to burn for 

 several centuries without the addition of any fuel. The work is chiefly of antiquarian interest.
