## Abstract

(1)MR. ROBERTSON'S “Shilling Arithmetic” deserves the attention of the teacher if only for the collection of carefully devised and arranged original examples. It is not overloaded with text, nor is undue space given to illustrative examples. Stress is laid upon the use of rough checks. No use is made in H.C.F. of the principle ma±nb. In finding prime factors the child is told to begin by removing the lowest factors first, a practice which does not make for speed, especially as the tests for divisibility by 11, 9, etc., are supposed to be at the service of the student. In the sections on fractions the figures are too small, and in the copy that has reached us they are often of varying degrees of distinctness. It is nothing short of criminal for any publishing firm in these days to issue books for the young upon which any reproach of the kind can be cast. Numbers 24 and 25 (p. 47) are instances of wickedly small type, and the strain to young eyes is greater still when the space between the lines is inadequate, e.g. compare numbers 26—40 on this page with numbers 41—43 on the next, and the relief is instantaneous.
