It may then be seen that in obedience to principles and practice well understood, true amateurs sip their wine. Every mouthful thus gives them the sum total of pleasure which they would not have enjoyed had they swallowed it at once. The same thing takes place, with however much more energy, when the taste is disagreeably affected. Just look at the patient of some doctor who prescribes immense doses of black medicine, such as were given during the reign of Louis XIV. The sense of smell, like a faithful counsellor, foretells its character. The eyes expand as they do at the approach of danger; disgust is on the lips and the stomach at once rebells. He is however besought to take courage, gurgles his throat with brandy, closes his nose and swallows. As long as the odious compound fills the mouth and stuns the organ it is tolerable, but when it has been swallowed the after drops develop themselves, nauseous odors arise, and every feature of the patient expresses horror and disgust, which the fear of death alone could induce him to bear. If the draught be on the contrary merely insipid, as for instance a glass of water, there is neither taste nor after taste. Nothing is felt, nothing is experienced, it is swallowed, and all is over. ORDER OF THE IMPRESSIONS OF TASTE. Taste is not so richly endowed as the hearing; the latter can appreciate and compare many sounds at once; the taste on the contrary is simple in its action; that is to say it cannot be sensible to two flavors at once. It may though be doubled and multipled by succession, that is to say that in the act of swallowing there may be a second and even a third sensation, each of which gradually grows weaker and weaker and which are designated by the words AFTER-TASTE, perfume or fragrance. Thus when a chord is struck, one ear exercises and discharges many series of consonances, the number of which is not as yet perfectly known. Those who eat quickly and without attention, do not discern impressions of the second degree. They belong only to a certain number of the elect, and by the means of these second sensations only can be classed the different substances submitted to their examination. These fugitive shadows for a long time vibrate in the organ of taste. The professors, beyond doubt, always assume an appropriate position, and when they give their opinions they always do so with expanded nostrils, and with their necks protruded far as they can go. ENJOYMENTS DUE TO THE TASTE. Let us now look philosophically at the pleasure and pain occasioned by taste. The first thing we become convinced of is that man is organized so as to be far more sensible of pain than of pleasure. In fact the imbibing of acid or bitter substances subjects us to sensations more or less painful, according to their degree. It is said that the cause of the rapid effects of hydrocyanic acid is that the pain is so great as to be unbearable by the powers of vitality.
