In the other senses we have remarked, that smooth things are relaxing.  Now it ought to appear that sweet things, which are the smooth of taste, are relaxing too.  It is remarkable, that in some languages soft and sweet have but one name. Doux in French signifies soft as well as sweet.  The Latin dulcis, and the Italian dolce, have in many cases the same double signification.  That sweet things are generally relaxing, is evident; because all such, especially those which are most oily, taken frequently, or in a large quantity, very much enfeeble the tone of the stomach.  Sweet smells, which bear a great affinity to sweet tastes, relax very remarkably.  The smell of flowers disposes people to drowsiness; and this relaxing effect is further apparent from the prejudice which people of weak nerves receive from their use.  It were worth while to examine, whether tastes of this kind, sweet ones, tastes that are caused by smooth oils and a relaxing salt, are not the originally pleasant tastes.  For many, which use has rendered such, were not at all agreeable at first.  The way to examine this is, to try what nature has originally provided for us, which she has undoubtedly made originally pleasant; and to analyze this provision. Milk is the first support of our childhood.  The component parts of this are water, oil, and a sort of a very sweet salt, called the sugar of milk.  All these when blended have a great smoothness to the taste, and a relaxing quality to the skin.  The next thing children covet is fruit, and of fruits those principally which are sweet; and every one knows that the sweetness of fruit is caused by a subtle oil, and such a salt as that mentioned in the last section.  Afterwards custom, habit, the desire of novelty, and a thousand other causes, confound, adulterate, and change our palates, so that we can no longer reason with any satisfaction about them.  Before we quit this article, we must observe, that as smooth things are, as such, agreeable to the taste, and are found of a relaxing quality; so on the other hand, things which are found by experience to be of a strengthening quality, and fit to brace the fibres, are almost universally rough and pungent to the taste, and in many cases rough even to the touch.  We often apply the quality of sweetness, metaphorically, to visual objects.  For the better carrying on this remarkable analogy of the senses, we may here call sweetness the beautiful of the taste.
