Arithmetic, Theoretical and Practical. By W. H. Girdlestone, (Rivingtons.) Arithmetic,

Step by Step. By Henry Caubes and Edwin Hines. Arithmetical Tables in Rhyme. By Rev. H. C. Davies. (Dean and Son.)—Ever since the Bishop of Natal turned his attention to the Pentateuch, arithmeticians have formed the dangerous- classes of reli- gious society. We must therefore request our readers to dispense with any critical examination of the three works which we have pladed at the head of this notice. Our orthodoxy ought to be above suspicion. It might not be proof against attack if we once embarked on the sea of figures. Perhaps the third of these books is the least likely to lead any one into error, as the author has emulated, or rather surpassed, his predecessors to whom we owe the poems of "Thirty Days hath Septem- ber" and "Multiplication is-Vexation." But even in these the germs of scepticism might be detected. " Povero Zannetto !" said Rousseau, " hada le donne, e studia la matematica." But some teachers now would leave mathematics and study the old women.
