A very interesting book he has made of it.”—Publishers’ Circular.

Mr. Hinton tries to explain the theory of the fourth dimension so that the ordinary reasoning mind can get a grasp of what metaphysical mathematicians mean by it. If he is not altogether successful it is not from want of clearness on his part, but because the whole theory comes as such an absolute shock to all one’s preconceived ideas.”—Bristol Times.

Mr. Hinton’s enthusiasm is only the result of an exhaustive study, which has enabled him to set his subject before the reader with far more than the amount of lucidity to which it is accustomed.”—Pall Mall Gazette.

The book throughout is a very solid piece of reasoning in the domain of higher mathematics.”—Glasgow Herald.

Those who wish to grasp the meaning of this somewhat difficult subject would do well to read The Fourth Dimension. No mathematical knowledge is demanded of the reader, and any one, who is not afraid of a little hard thinking, should be able to follow the argument.”—Light.

A splendidly clear re-statement of the old problem of the fourth dimension. All who are interested in this subject will find the work not only fascinating, but lucid, it being written in a style easily understandable. The illustrations make still more clear the letterpress, and the whole is most admirably adapted to the requirements of the novice or the student.”—Two Worlds.

Those in search of mental gymnastics will find abundance of exercise in Mr. C. H. Hinton’s Fourth Dimension.”—Westminster Review.
