Nevertheless, it is a fact that this anti-tannic tea-pot has many excellent points about it, and is sure to meet with favour. It is really an attempt to make tea by a more certain method than is generally employed; for I think it must be admitted that the present happy-go-lucky style has not much to recommend it. On one occasion the tea will be excellent--and on another either as weak as water, or with such a sharp acrid taste that it is almost undrinkable. In the latter case the tea has been allowed to soak so long that it has become a decoction instead of an infusion. The consequence of this prolonged action of the hot water on the tea is that it brings out the bitter extractive material of the plant, and it is this which proves so particularly pernicious. 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.
