Opinions Of The Press

"This series, besides affording popular but sound instruction on scientific subjects, with which the humblest man in the country ought to be acquainted, also undertakes that teaching of 'common things' which every well-wisher of his kind is anxious to promote. Many thousand copies of this serviceable publication have been printed, in the belief and hope that the desire for instruction and improvement widely prevails ; and we have no fear that such enlightened faith will meet with disappointment. " - Times.

"A cheap and interesting publication, alike informing and attractive. The papers combine subjects of importance and great scientific knowledge, considerable inductive powers, and a popular style of treatment." - Spectator.

"The 'Museum of Science and Art' is the most valuable contribution that has ver been made to the Scientific Instruction of every class of society." - Sir David Brewster in the North British Revieiv.

"Whether we consider the liberality and beauty of the illustrations, the charm of the writing, or the durable interest of the matter, we must express our belief that there is hardly to be found among the new books, one that would be welcomed by people of so many ages and classes as a valuable present." - Examiner.
