N.S.W. Educational Gazette: “A masterly and elaborate treatise for the use of schools on a subject of world-wide interest and importance.... In commercial life a knowledge of the metric system has been for some years essential, and it is, therefore, fitting that its underlying principles should be taught in our schools concurrently with reduction, and practised systematically in the more advanced grades. For this purpose the book is unquestionably the best we have seen.”

N.S.W. Educational Gazette: “The most complete and logical discussion of this part of the works of the great geometer that we have seen. An unusual amount of care has been bestowed on the initiatory stages, the definitions, axioms, and postulates being treated with commendable fulness.... The brevity, simplicity, and perspicuity of his methods will appeal forcibly to students.... Mr. Maclardy adheres to the plan of simplifying the proofs and reducing the verbiage to a minimum, and has added a contribution to mathematical literature which we regard as indispensable.”
