This is an interesting account of the author's travels, as surgeon, with the army which, in 1847, under General Scott, fought its way through the historical battles of Contreras, Churubusco, Molino del Rey, to Chapultepec: and the final entrance, on the 14th of September, to the Mexican capital. The description of the appearance of the valley of Mexico, as the army descended the mountain side, is very beautiful. The author says, "The valley or basin of Mexico lay spread out like a panorama of fairy land; opening, closing, and shifting, according to the changing positions of the observers. At times nothing would be visible but dark recesses in the mountain, or the grim forest that shaded the road; when in a moment a sudden turn would unfold, as if by magic, a scene that looked too lovely to be real. It was an enchantment in nature; for, knowing as we did that we beheld _bona fide_ lakes and mountains, plains and villages, chapels and hamlets, all so bright, so clear, and so beautiful, it still seemed an illusion of the senses, a dream, or a perfection of art--nay, in the mountain circle we could see the very picture-frame." How long the mixed races of this beautiful country are to continue their tragical and at times ludicrous efforts at self-government is a problem to be solved in the future. An Epistle On Homoeopathy. The doctor's logical arguments in this article we would recommend to the perusal of our friends who prefer the more palatable medicine of that school, Lecture On Hygiene. A Lecture On Health And Happiness. These lectures contain many sound practical hints for the general reader whereby he may avoid many causes of disease, and prolong his life to a natural limit. We give the doctor's testimony on two interesting points. He says: "Excesses at table are disastrous enough, and in this they are worse than over devotion to Bacchus; namely, that they undermine more slowly and more insidiously; but otherwise, strong drinks are vastly worse. There are persons who think wines and liquors essential to health; but as the rule, they are useless at best; and at worst, destructive to soul, and body, and mind. Strict total abstinence is generally, I might say universally safe; while even temperate indulgence is rarely safe or salutary." (P. 119.)
