ABSTRACT
In reviewing the immense progress made in every direction during "The Century of Peace,' it is not at first sight easy to discover what is most necessary for us to notice. There is no branch of science, of manufactures, or of arts, that did 51not partake of most extensive improvement. In such conversations as these it is wholly out of the question that we can enter into the numberless details that fill up a history of the period; indeed we can only glance very cursorily at some of them. Since I have laid considerable stress upon your study of locomotion and the means used to effect it, we will pay chief attention to that first, more particularly as it will lead us into an examination of the laws affecting natural motion, that is of force, and man's increasing knowledge thereof.
