The description above given of the feeling that remains, when the different modifications of resistance are deducted, is scarcely adequate to represent the reality. Frequently it is true of them, that they 'are mostly moderate, partaking very little of either pain or pleasure,' but there are occasions when they rise into prominence and power. We may refer to the contact of the bedclothes at night, when the body is relieved from the tight and deadening embrace of the ordinary clothing. The case of greatest moment, however, is the contact of one human being or animal with another; such contact being the physical element in the tender as well as in the sexual affections. There is a combination of tactile sensibility and warmth in this instance, each counting for a part of the pleasure. The influence is well enough known as experienced among human beings; but the sphere of its operation in animals has been but imperfectly explored. If we observe carefully the first movements of a new-born animal, a mammal for example, we find that the guiding and {36} controlling sensation of its first moments, is the contact with the mother. In that contact, it finds satisfaction and repose; in separation, it is in discomfort and disquiet. Its earliest volitions are to retain and to recover the soft warm touch of the maternal body. When it commences sucking, and has the sensation of nourishment, a new interest springs up, perhaps still more powerful in its attractions, and able to supersede the first, or at least to put it into a second place; yet, during the whole period of maternal dependence, the feeling of touch is a source of powerful sensibility both to the mother and to the offspring. Among animals born in litter, as pigs, kittens, &c., the embrace is equally acceptable between the fellow-progeny themselves. The sensual pleasure of this contact is the essence, the fact, of animal affection, parental and fraternal; and it is the germ, or foundation, and concomitant of tender affection in human beings. It is the experience of this agreeable contact that prepares the way for a still closer conjunction after the animal reaches puberty. Independent of, and antecedent to, that still more acute sensibility, there is a pleasure in the warm embrace of two animals, and they are ready to enter upon it, at all times when the other interests, as nourishment, exercise and repose, are not engrossing. The play of animals with one another clearly involves the pleasure of the embrace, even without sexuality; and it leads to the sexual encounter at the ripe moment.--_B._] {37} SECTION VI.
