The chemist Laplace explained to Napoleon the results of various methods of manipulation. “How is it, Sir,” said the Emperor, “that a glass of water in which I melt a lump of sugar, always appears to me to be superior in taste to one in which I put the same quantity of powdered sugar?” “Sire,” said the sage, “there exist three substances, whose elements are precisely the same; namely, sugar, gum, and starch. They only differ under certain conditions, the secret of which Nature has reserved to herself; and I believe that it is possible, that, by the collision caused by the pestle, some of the portions of the sugar pass into the condition of gum or starch, and thence arises the result which has been observed.”

Medical men are widely at issue as to the merits of coffee. All, however, are agreed that it stimulates the brain, and banishes somnolency. Voltaire and Buffon were great coffee-drinkers; but I do not know that we are authorized to attribute the lucidity of the one or the harmony of the other to the habit in question. Ability would be cheaply purchased if that were the case; and the “royal road” would have been discovered where it had never been looked for.

The sleeplessness produced by coffee is not one of an unpleasant character. It is simply a painless vigilance; but, if often repeated, it may be exceedingly prejudicial. Brillat de Savarin illustrates the power of coffee by remarking, that a man may live many years who takes two bottles of wine daily; but the same quantity of strong coffee would soon make him imbecile, or drive him into a consumption.

Taken immediately after dinner, coffee aids the dyspeptic, especially to digest fat and oily aliment, which, without such stimulant, would undoubtedly create much disturbance. The Turks drink it to modify the effects of opium. Café au lait, that is, three parts milk to one of coffee, is the proper thing for breakfast; but the addition of milk to that taken after dinner is a cruelty to the stomach. A Dutchman, named Nieudorff, is said to have been the first who ventured on the experiment of mixing milk with coffee. When he had the courage to do this, the two liquids together were considered something of such an abomination as we should now consider brown sugar with oysters.

I must not omit to mention, that the favourite beverage of Voltaire, at the Café Procope, was “choca,”—a mixture of coffee (with milk) and chocolate. The Emperor Napoleon was as fond of the same mixture as he was of Chambertin; and, in truth, I do not know a draught which so perfectly soothes and revives as that of hot, well-frothed “choca.”

Substances mixed with coffee, or substitutes for the berry altogether, have been tried with various degrees of success. Roasted acorns have been made to pass for it when ground. There is more chicory than coffee consumed at the present time in France; and the infusion of the lupin does duty for it at poor hearths in Flanders; as that of roasted rye (the nearest resemblance to coffee) does in America. Experimentalists say, that an excellent substitute for coffee may be made from asparagus; and Frankfort, alarmed lest the complications of the “Eastern Question” should deprive it of the facilities for procuring the berry as heretofore, is gravely consulting as to whether asparagus coffee may be a beverage likely to be acceptable as a substitute for the much prized “demi-tasse.”

CHOCOLATE.

Ferdinand Cortez went to Mexico in search of gold; but the first discovery he made was of chocolate. The discovery was not welcomed ecclesiastically, as coffee was. This new substance was considered a sort of wicked luxury, at least for Monks, who were among the earliest to adopt it, but who were solemnly warned against its supposed peculiar effects. The moralists quite as eagerly condemned it; and in England Roger North angrily asserted, that “the use of coffee-houses seems much improved by a new invention, called ‘chocolate-houses,’ for the benefit of rooks and cullies of quality, where gambling is added to all the rest, and the summons of W—— seldom fails; as if the devil had erected a new university, and these were the colleges of its Professors, as well as his schools of discipline.” The Stuart jealousy of these localities, where free discussion was amply enjoyed, seems to have influenced the Attorney-General of James II.; for, although they may not have been frequented, he says, by “the factious gentry he so much dreaded,” he adds, “This way of passing time might have been stopped at first, before people had possessed themselves of some convenience from them of meeting for short dispatches, and passing evenings with small expenses.” Of what chiefly recommended these places, the stern official thus made a grievance.

Chocolate (or, as the Mexicans term it, chocolalt) is the popular name for the seeds of the cocoa, or, more correctly, the cacao, plant, in a prepared state, generally with sugar and cinnamon. The Mexicans improve the flavour of the inferior sorts of cacao seeds by burying them in the earth for a month, and allowing them to ferment. The nutritious quality of either cacao or chocolate is entirely owing to the oil or butter of cacao which it contains. Cacao-nibs, the best form of taking this production, are the seeds roughly crushed. When the seed is crushed between rollers, the result is flake cacao. Common cacao is the seed reduced to a paste, and pressed into cakes. The cheap kinds of chocolate are said to be largely adulterated with lard, sago, and red-lead,—a pernicious mixture for healthy stomachs; but what must it be for weak stomachs craving for food at once nutritious and easy of digestion? The “patent” chocolates of the shops are nothing more than various modes of preparing the cacao seeds.

The ladies of Mexico are so excessively fond of chocolate, that they not only take it several times during the day, but they occasionally have it brought to them in church, and during the service. A cup of good chocolate may, indeed, afford the drinker strength and patience to undergo a bad sermon. The Bishops opposed it for a time, but they at length closed their eyes to the practice. I am afraid there is no chance of the fashion being introduced into England. The advantages would be acknowledged; but then there would be a savour of Popery detected about it, that would inevitably cause its rejection. The Church herself found a boon in this exquisite supporter of strength. The Monks took it of a morning before celebrating Mass, even in Lent. The orthodox and strong-stomached raised a dreadful cry at the scandal; but Escobar metaphysically proved, that chocolate made with water did not break a fast; thus establishing the ancient maxim, “Liquidum non frangit jejunium.
