 wise a sound copy) ; RARE, £1. 10^ Parisiis, ex officina Rob. Stephani, 1538 



The first work on arithmetic by an English author, and 'decidedly the most classical book which ever was written on 

 the subject in Latin, both in purity of style and goodness of matter. The author had read everything on the subject, in 

 every language which he knew . . . and had spent much time in licking what he found into shape. For plain common 

 sense, well expressed, and learning most visible in the habits it had formed, Tonstall's book has been rarely surpassed, 

 and never in the subject of which it treats.'— Pro/, de Morgan. 



The book is dedicated to his friend Sir Thomas More, and gains further interest as showing the greatest figure in the 

 Catholic as opposed to the Genevan Reformation in England as a proficient in the exact sciences of a very high order for 

 his time.
