THE purpose of Prof. Karpinski's book is to present the development of arithmetical knowledge as a vital part of the history of civilisation. Particular attention is paid to the material of arithmetic taught in American elementary schools and to the historical phases of that work with which the teacher of arithmetic should be familiar. The book also contains a bibliography of the early American text-books of arithmetic printed before 1800, and refers to many of the early popular treatises on the subject used in England.
