useful pamphlet is a popular restatement of the chief facts and arguments derived from science, upon which the opponents of alcoholic beverages rest their case. For his motto, Colonel Dudley quotes the pithy observation of Dr. Willard Parker that "the laws of health are the laws of God, and as binding on man as the Decalogue;" and he then proceeds to show how the laws of health are violated by the use of spirituous drinks. The author does not profess to have made any new contributions to the question, but only to present the opinions of eminent authorities, who have given great attention to the subject. His pages present many startling facts suited to awaken serious reflection on the part of those who are in danger from the use of alcoholic beverages, but the freshest portion of the statement is his exposé of the outrageous system of cheating practised by the dealers in spirits. Of all the frauds of commerce, according to this writer, none will for a moment bear comparison with the adulterations and sophistications of intoxicating liquors. He gives recipes enough for the manufacture of all kinds of choice liquors to start a manufacturer in business, and shows, by the cheapness of the material used, how immensely profitable such a business must be. To the rising generation, who cannot have the benefit of the teachings of the old temperance campaign, such works as this of Colonel Dudley will prove valuable, and its wide circulation among them is to be strongly commended.

The cultivation of a healthy public sentiment is regarded as the only cure.

paper records a series of experiments undertaken to ascertain the character and position of neutral axes (unstrained parts) in beams and columns under pressure, and attempts to establish, as the result of such experiments, "that the neutral axis is a flexible line truly parallel to the top and bottom sides of the rectangular beam, and passing through the centres of gravity of its sections only when the load is evenly distributed from end to end; . . . but that, when there is a local pressure, the neutral axis is more or less governed in its direction and form by the strain passing from the point of local pressure to the point of support."
