"This work of Baron Liebig is one of those books from which the mind desiring healthy philosophical instruction can receive it, in a most pleasant and yet most perfect form. There is no necessity for an acquaintance with all the intricacies of scientific nomenclature and terminology; with a moderate amount of chemical knowledge as a basis, no man of ordinary intellect will rise from the perusal of these Letters without the feeling that he has partaken of a wholesome intellectual feast."-British Medical Journal.

"This and the preceding volumes of Dr. Lardner's Handbook occupy a remarkable place in literature. While on the one hand they are examples of the extreme simplification of which the statement of the laws by which natural phenomena are regulated is capable, on the other they are illustrations of the care and method with which the true philosopher invariably treats the truths of Science."-Mechanics' Magazine.

"The 'Museum of Science and Art' is the most valuable contribution that has ever been made to the scientific instruction of every class of society."-Sir David Brewster in the North British Review.

"The whole work, bound in six double volumes, costs but the price of a Keepsake; and 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.
