PRESS NOTICES.

"A most fascinating volume, treating of phenomena in which all are interested, in a delightful style and with wonderful clearness. For lightness of touch and yet solid value of information the chapter 'Why Has Man Two Eyes?' has scarcely a rival in the whole realm of popular scientific writing."--The Boston Traveller.

"Truly remarkable in the insight they give into the relationship of the various fields cultivated under the name of Physics.... A vein of humor is met here and there reminding the reader of Heaviside, never offending one's taste. These features, together with the lightness of touch with which Mr. McCormack has rendered them, make the volume one that may be fairly called rare. The spirit of the author is preserved in such attractive, really delightful, English that one is a.s.sured nothing has been lost by translation."--Prof. Henry Crew, in The Astrophysical Journal.

"A very delightful and useful book.... The author treats some of the most recondite problems of natural science, in so charmingly untechnical a way, with such a wealth of bright ill.u.s.tration, as makes his meaning clear to the person of ordinary intelligence and education.... This is a work that should find a place in every library, and that people should be encouraged to read."--Daily Picayune, New Orleans.

"In his translation Mr. McCormack has well preserved the frank, simple, and pleasing style of this famous lecturer on scientific topics. Professor Mach deals with the live facts, the salient points of science, and not with its mysticism or dead traditions. He uses the simplest of ill.u.s.trations and expresses himself clearly, tersely, and with a delightful freshness that makes entertaining reading of what in other hands would be dull and prosy."--Engineering News, N. Y.

"The general reader is led by plain and easy steps along a delightful way through what would be to him without such a help a complicated maze of difficulties. Marvels are invented and science is revealed as the natural foe to mysteries."--The Chautauquan.

"The beautiful quality of the work is not marred by abstruse discussions which would require a scientist to fathom, but is so simple and so clear that it brings us into direct contact with the matter treated."--The Boston Post.

"A masterly exposition of important scientific truths."--Scotsman, Edinburgh.

"These lectures by Dr. Mach are delightfully simple and frank; there is no dryness or darkness of technicalities, and science and common life do not seem separated by a gulf.... The style is admirable, and the whole volume seems gloriously alive and human."--Providence Journal, R. I.

"The non-scientific reader who desires to learn something of modern scientific theories, and the reasons for their existence, cannot do better than carefully study these lectures. The English is excellent throughout, and reflects great credit on the translator."--Manufacturer and Builder.

"We like the quiet, considerate intelligence of these lectures."--Independent, New York.

"Professor Mach's lectures are so pleasantly written and illumined with such charm of ill.u.s.tration that they have all the interest of lively fiction."--New York Com. Advertiser.

"The literary and philosophical suggestiveness of the book is very rich." Hartford Seminary Record.

"All are presented so skilfully that one can imagine that Professor Mach's hearers departed from his lecture-room with the conviction that science was a matter for abecedarians. Will please those who find the fairy tales of science more absorbing than fiction."--The Pilot, Boston.

"Professor Mach ... is a master in physics.... His book is a good one and will serve a good purpose, both for instruction and suggestion."--Prof. A. E. Dolbear, in The Dial.

"The most beautiful ideas are unfolded in the exposition."--Catholic World, New York.

"A wonderfully original little book. Like everything he writes a work of genius."--Prof. W. James of Harvard.

"I consider each work of Professor Mach a distinct acquisition to a library of science."--Prof. D. W. Hering, New York University.

"There is no work known to the writer which, in its general scientific bearings, is more likely to repay richly thorough study. We are all interested in nature in one way or another, and our interests can only be heightened and clarified by Mach's wonderfully original and wholesome book. It is not saying too much to maintain that every intelligent person should have a copy of it,--and should study that copy."--Prof. J. E. Trevor, Cornell.

"Students may here make the acquaintance of some of the open questions of sensation and at the same time take a lesson in the charm of scientific modesty that can hardly be excelled."--Prof. E. C. Sanford, Clark University.

"It exhibits keen observation and acute thought, with many new and interesting experiments by way of ill.u.s.tration. Moreover, the style is light and even lively--a rare merit in a German prose work, and still rarer in a translation of one."--The Literary World, London.
