Such points, however, may be left to the chemist, the physician, or the physiologist; our purpose is rather to indicate briefly the social aspects of the subject, the social causes, conditions, and consequences of that narcotism which is, if not yet a prevalent, certainly a rapidly-spreading habit. The desire or craving for stimulants in the most general sense of the word—for drugs acting upon the nerves whether as excitant or sedative agents—is an almost if not absolutely universal human appetite; so general, so early developed, that we might almost call it an instinct. Alcohol, of course, is the most popular, under ordinary circumstances the most seductive, and by far the most widely diffused of all stimulant substances. From the Euphrates to the Straits of Dover, the vine has been from the earliest ages second only to corn in popular estimation; wine, next to bread, the most prized and most universal article of human food. The connection between _Ceres_ and _Bacchus_ is found in almost every language as in the social life of every nation, from the warlike Assyrian monarchy, the stable hierocratic despotism of Egypt, to the modern French Republic and German Empire. Corn itself has furnished stimulant second in popularity to wine alone; the spirit which delighted the fiercer, sterner races of Northern Europe—Swede, Norwegian, and Dane, St. Olaf, and Harold Hardrada, as their descendants of to-day; and the ale of our own Saxon and Scandinavian ancestry, which neither spirit, cider, nor Spanish wine has superseded among ourselves. The vine, again, seems to have been native to America; but the civilized or semi-civilized races of the southern and central part of the Western Continent had other more popular and more peculiar stimulants, also for the most part alcoholic. The palm, again, has furnished to African and Asiatic tribes a spirit not less potent or less noxious, not less popular and probably not less primitive, than whiskey or beer. But where alcohol has been unknown, among races to whose habits and temperament it was alien, or in climates where so powerful an excitant produced effects too palpably alarming to be tolerated by rulers or law-givers royal or priestly, other and milder stimulants or sedatives are found in equally universal use. Till the white man introduced among them his own destructive beverages, till the “fire-water” spread demoralization and disease, tobacco was the favorite indulgence of the Red Indian of North America, and very probably of that mighty race which preceded them and seems to have disappeared before they came upon the scene—the Mound-builders, whose gigantic works bear testimony to the existence of an agriculture scarcely less advanced or less prolific, a despotism probably not less absolute than that of Egypt. Coffee has for ages been almost equally dear to the Arabs; tea has been to China all that wine is and was to Europe, probably from a still earlier period, and has taken hold on
