cases relationships in things which we have observed to be amusing. Some forms are so general that they will produce a vast number of jests, and we thus seem to have some insight into the influences that awaken humour, but we see only approximately and superficially, and can merely produce good results occasionally—rather by an accident than with any certainty.

ORIGIN OF HUMOUR.

Few of the blessings we enjoy are of greater value than the gift of humour. The pleasure attendant upon it attracts us together, forms an incentive, and gives a charm to social intercourse, and, unlike the concentrating power of love, scatters bright rays in every direction. That humour is generally associated with enjoyment might be concluded from the fact that the genial and good-natured are generally the most mirthful, and we all have so much personal experience of the gratification it affords, that it seems superfluous to adduce any proofs upon the subject. "Glad" is from the Greek word for laughter, and the word "jocund" comes from a Latin term signifying "pleasant." But we can trace the results of this connection in our daily observation. How comes it to pass that many a man who is the life and soul of social gatherings, and keeps his friends in delighted applause, sits, when alone in his study, grave and sedate, and seldom, if ever, smiles in reading or meditation? Is it not because humour is a source of pleasure? We are not joyously disposed when alone, whereas in society we are ready to give and receive whatever is bright and cheering.
The first question which now presents itself is what is laughter? and our answer must be that it is a change of countenance accompanied by a spasmodic intermittent sound—a modification of the voice—but that we cannot trace its physical origin farther than to attribute it to some effect produced upon the sympathetic nerve, or rather the system of nerves termed respiratory. These communicate with every organ affected in mirth, but the ultimate connection between mind and body is hidden from our view.
In all laughter there is more or less pleasure, except in that of hysteria, when by a sudden shock the course of Nature is reversed, and excessive grief will produce the signs of joy, as extravagant delight will sometimes exhibit those of sorrow. We should also exclude the laughter caused by inhalation of gas, and that of maniacs, which arising from some strange and unaccountable feeling is abnormal and imperfect, and known by a hollow sound peculiar to itself. None of these kinds of laughter are primary, they are but imperfect reflections of our usual modes of expression, and, excepting such cases, we may agree that M. Paffe is correct in observing that "Joy is an indispensable condition of laughter." Dr. Darwin refers to the laughter of idiots to prove that it may be occasioned by pleasure alone. Strangely enough, he quotes as an instance in point the fact of an idiot boy having laughed at receiving a black eye.
Proceeding onwards, we next come to inquire why the sense of humour is expressed by voice and countenance, and does not merely afford a silent and secret delight? The answer may be given, that one object, at least, is to increase social communication and multiply pleasure. The well-being of the animal world largely depends upon the power of each member of it to communicate with others of the same species. They all do so by sound and gesture, probably to a larger extent than we generally imagine. A celebrated physician lately observed to me that "all animals have some language." How far mere signs deserve so high a name may be questioned. But man has great powers of intercourse, and it is much owing to his superior faculties in this respect that he holds his place so high above the rest of creation. Orators, who make it their study to be impressive, give full importance to every kind of expression, and say that a man should be able to make his meaning understood, even when his voice is inaudible. It has been lately discovered that the mere movement of the lips alone, without sound, is sufficient to convey information.[2] Facial expression has been given us as a means of assisting communication, and smiles and laughter have become the distinctive manifestations of humour. Thus the electric spark passes from one to another, and the flashing eye and wreathed lip lights up the world. Profit also accrues—fear of being laughed at leads us to avoid numerous small errors, and by laughing at others we are enabled to detect shortcomings in ourselves.
Sympathetic laughter does not arise from any contemplation of ludicrous circumstances, but is only a sort of reflection of the feelings of others. There seems to be little intelligence in it, but something almost physical, just as yawning is infectious, or as on seeing a person wounded in a limb we instinctively shrink ourselves in the same part of the body. Even a picture of a man laughing will have some effect upon us, and so have those songs in which exuberant mirth is imitated. Thus we often laugh without feeling just cause, as we often feel cause without laughing. All exhibitions of emotion are infectious. We feel sad at seeing a man in grief, although the source of his sorrow is unknown to us; and we are inclined to be joyous when surrounded by the votaries of mirth. Not unfrequently we find a number of persons laughing, when the greater part of them have no idea what is the cause of the merriment. Sometimes we cannot entirely resist the impulse, even when we ourselves are the object of it, so much are we inclined to enter into the feelings and views of those who surround us. In this, as well as in many other cases, the sight and proximity of others exercise over us a great influence, and sometimes almost a fascination.
To this sympathy we are largely indebted for the diffusion of high spirits. It is pleasant to laugh and see others laughing, and thus the one leads to the other. "Laugh and be fat," is a proverb, and it has been well observed that "we like those who make us laugh," because they give us pleasure. We may add that we like to see others joyous, because we feel that we are surrounded by kindly natures. A gallant writer tells us that he hopes to be rewarded for his labours in the field of literature by "the sweetest of all sounds in nature—the laughter of fair women." Macready, speaking of this influence, says:
"The words of Milman would have applied well to Mrs. Jordan, 'Oh, the words laughed on her lips!' Mrs. Nesbitt, the charming actress of a late day, had a fascinating power in the sweetly-ringing notes of her hearty mirth; but Mrs. Jordan's laugh was so rich, so apparently irrepressible, so deliciously self-enjoying, as to be at all times irresistible."
The agreeable influence of smiles is so well known that many are tempted to counterfeit them, and assume an expression in which the eye and lip are in unhappy conflict.[3] On the other hand, painful thoughts are inimical to mirth. No sally of humour will brighten the countenance of a man who has lately suffered a severe loss, and even mental reflection will extinguish every sparkle. But the bed of sickness can often be better cheered by some gay efflorescence, some happy turn of thought, than by expressions of condolence. Galen says that Æsculapius wrote comic songs to promote circulation in his patients; and Hippocrates tells us that "a physician should have a certain ready humour, for austerity is repulsive both to well and ill." The late Sir Charles Clark recognised this so far that one of his patients told me that his visits were like a bottle of Champagne; and Sir John Byles observes, "Cheerfulness eminently conduces to health both of body and mind; it is one of the great physicians of nature.
