boor may laugh on being tickled, but a man must have intelligence to be amused by wit. The senses which are the least discriminating are the least productive of humour, little is derived from that of smell or of taste, though we may talk sometimes of an educated palate and an acquired taste. The finer organs of sight and hearing are the chief mediums of humour, but the sense of touch might by education be rendered exquisitely sensitive, and Dickens mentions the case of a girl he met in Switzerland who was blind, deaf, and dumb, but who was constantly laughing. Among infants, also, where very slight complication is required, the sense of humour can be excited by touch. Thus nurses will sing, "Brow brinky, eye winkey, nose noppy, cheek cherry, mouth merry," and greatly increase the little one's appreciation by, at the same time, touching the features named. Contact with other bodies occasions a sensation, and might, by degrees, awaken an emotion; and we might thus have such a sense of the ludicrous as that obtained through eye and ear, which is sometimes almost intuitive, and but slightly derived from reflection or experience. Of this kind is that aroused by the rapid changes of form and colour of the kaleidoscope, and those pantomimic representations which amuse the young and uneducated, and others who live mostly in the senses.

We have now arrived at the emotional phase of laughter, that in which emotion far exceeds intellectual action. At this stage, we have a kind of laughter which we may call that of pleasure, inasmuch as it is the first that deserves a distinct name. This laughter of pleasure required very little complication of thought, contained no unamiable feeling, and expressed the mildest sense of the ludicrous. At the same time, it did not flow from any mere constitutional joyousness, but only arose upon certain occasions, in consequence of some remarkable and unusual occurrence—such as the reception of glad tidings, or the sudden acquisition of some good fortune. This ancient laughter, now no longer existing, is alluded to in early writings.

Thus we read in Gen. xxi. 6, that Sarah, on the birth of Isaac, said "God hath made me to laugh, so that all that hear will laugh with me," and in Ps. cxxvi., "When the Lord turned again the captivity of Zion, we were like them that dream. Then was our mouth filled with laughter, and our tongue with singing." And in Proverbs we find, "There is a time to weep, and a time to laugh," contrasting the expression of sorrow with that of pleasure. Passing into Greek literature, we find laughter constantly termed "sweet." In Iliad xxi, "Saturn smiled sweetly at seeing his daughter;" in xxiii. "The chiefs arose to throw the shield, and the Greeks laughed, i.e., with joy." In Odyssey, xx. 390, they prepare the banquet with laughter. Od. xxii., 542, Penelope laughs at Telemachus sneezing, when she is talking of Ulysses' return; she takes it for a good omen. And in the Homeric Hymns, which, although inferior in date to the old Bard, are still among the earliest specimens of literature, we find, in that to Mercury, that the god laughs on beholding a tortoise, "thinking that he will make a beautiful lyre out of its shell;" and a little further on, Apollo laughs at hearing the sound of the lyre. In the hymn to Aphrodite, the laughter-loving Venus laughed sweetly when she thought of men and mortals being intermarried. The fact that this and the preceding kinds of laughter were not necessarily regarded as intellectual, is evident from the ancient poets attributing them to vegetable and inorganic life. Considerable licence in personification must no doubt be conceded to those who went so far as to deify the elements, and to imagine a sort of soul in the universe, and no doubt language as well as feeling was not at the time strictly limited. But it must be remarked that, while they rarely attribute laughter to the lower animals, they also never ascribe any other sign of emotion, nor even that in its higher kinds, to insensate matter. In all these passages it is of a physical, or merely pleasurable description. In Iliad xiv. 362, speaking of the Grecian host, Homer says that "the gleam of their armour was reflected to heaven, and all the earth around laughed at the brazen refulgence."

In Hesiod's Theogony, v. 40, we read that when the Muses are singing "the palace of loud-thundering Jove laughs (with delight) at their lily voice;" and in the Hymn to Ceres we find Proserpine beholding a Narcissus, from the root of which a hundred heads sprang forth "and the whole heavens were scented with its fragrance, and the whole earth laughed and the briny wave of the sea." Theognis writes that Delos, when Apollo was born, "was filled with the ambrosial odour, and the huge earth laughed." The poets seemed scarcely to have advanced beyond such a bold similitude, and we may conclude that while they saw in laughter something above the powers of the brute creation, they did not consider that it necessarily expressed the smallest exercise of intellect.

This laughter of pleasure, which cheered the early centuries of the world, now no longer exists except perhaps in childhood. It belongs to simpler if not happier natures than our own. If a man were now to say that his friends laughed on hearing of some good fortune having come to him, we should suppose that they disbelieved it, or thought there was something ridiculous in the occurrence. In these less emotional ages, in which the manifestations of joy and sorrow are more subdued, it is mute, and has subsided into a smile. It is difficult to say when the change took place, but our finding smiles mentioned in Homer, though not in Scripture, might suggest their Greek origin, if they were at first merely a modification of the early laughter of pleasure, betokening little more than kindly or joyous emotions. Although not always now genial, the smile continues to be used for the symbol of pleasure, even in reference to inanimate Nature, as where Milton writes "Old Ocean smiled." The smile may have preceded laughter, as the bud comes before the blossom, but it may, on the other hand, have been a reduction of something more demonstrative.

We have still a kind of laughter approaching very nearly to that of pleasure, which contains little reflection, but cannot be regarded as simply physical. This description seems to be that alluded to in the Book of Ecclesiastes, "I said of laughter, it is mad, and of mirth, what good doeth it?" Of the same nature is that to which some excitable and joyous persons are constitutionally inclined. Their perpetual merriment seems to us childish and silly. Thus Steele observes to an hilarious friend, "Sir, you never laughed in your life," and farther on he remarks, "Some men laugh from mere benevolence."

The pleasure accompanying the perception of the ludicrous has been by some attributed to the exercise of certain muscles in the face, and by others to the acquisition of new ideas. But we may safely discard both theories, for the former derives the enjoyment from physical instead of mental sources, and the latter gives us credit for too great a delight in knowledge, even were it thus generally obtained. The enjoyment seems partly to arise from stimulation and activity of mind, excitement being generally agreeable, whereas inaction is monotonous and wearisome. But it seems also partly to be derived from sources which are, or appear to be, collateral. Thus, in the early laughter of pleasure, some solid advantage or gratification, present or future, was always in view, and from men being delighted at their own success, which must often have been obtained at the expense of others, it was an easy transition to rejoice at the failure of rivals. In those
