Tea at sea is proverbially unpalatable, and invariably disagrees, owing chiefly to the fact that it is a boiled decoction of tea leaves and nothing else. COFFEE Coffee is the roasted and ground product of the seeds found within the fruit of a tree, the Coffea Arabica. Originally a native of Abyssinia, it was transported into Arabia at the beginning of the fifteenth century. Since then it has been widely cultivated in the West Indies, in Ceylon, and in other warm countries. The fruit itself much resembles a small cherry in size and appearance, and usually contains two small seeds--the coffee beans themselves. The choicest coffee is the mocha or Arabian coffee, and the bean is very small. Of the West Indian varieties, the Jamaica and the Martinique coffee are the best. The exhilarating and agreeable properties of coffee are dependent in great part upon three active principles which it contains. The first of these is caffeine, which is almost identical in composition with, and practically the same as, the theine present in tea. Next there are the volatile oils, developed by roasting, from which coffee derives its aroma. Indeed, as far as they are concerned, there are many who believe that these ethereal oils have more to do with the characteristic properties of coffee than even the caffeine itself. And, lastly, there are the acids known as caffeo-tannic and caffeic acids, which are modified forms of tea tannin. They exist to a far less extent, however, than does the tannin in tea. Coffee has a decidedly stimulating effect upon the nervous system; so much so that in France it has been called UNE BOISSON INTELLECTUELLE (an intellectual beverage), from its stimulating all the functions of the
