This down on the chin is the same with young men, as the increase of the bosom with young girls. These two proofs of puberty announce, in both sexes, that sweet inquietude, the prelude of love and pleasure; those emotions, desires, and wants to be happy which nature has implanted in the human breast; and at the same time the power of reason.[42] “The beard,” says Theodoret in his fourth discourse on the Providence of God, “informs these young folks, who have this downy hair on their chin, that it is time to leave off childish plays, in order to employ themselves about more serious things.” ’Tis then the greater or less quantity of beard a man has that determines, in the same proportion, the vigour of his body; ’tis then that Nature, steady in her course, requires its increase, and there is no doubt but our perseverance in thwarting her will, injures the adjoining parts. Footnote 42: “It is at the time the Devil is in a passion that the beard begins to bud; and if ever a man has occasion to show some sign of courage or make some sensible observation, ’tis then his beard begins to come. _Pogonologia._” If it is evident that a long beard, by the equal heat which it maintains, procures glandulous bodies a mild perspiration, and that it draws away the humours intended by Nature for its nourishment, it cannot be denied but that, the beard being cut off, and neither the perspiration nor secretion having place, the humours, which ought to have produced both, take a different course and become prejudicial to the parts through which they are obliged to circulate. This is the sentiment of a very learned writer, who has examined the beard under this interesting point of view. “It is incontestable,” says he, “that a long beard contributes greatly to health, because, whilst it draws off the superfluous humours which nourish this mark of manhood, it preserves the teeth a long time from rotting, and strengthens the gums, an advantage which those who shave are generally deprived of, who, almost all, are tormented with a dreadful pain in the teeth, and lose them all before they are any way advanced in age. The beard, in summer,” continues the same author, “defends the face from the burning rays of the sun; and in winter from rimes. In short, it preserves a man from a number of disorders, such as the quinsy and the decay of the palate, &c.”[43] Adrian Junius, a physician who lived in the sixteenth century, in his commentary on the hair of the head, asserts that the beard is a preservative against several disorders. Gentien Hervet, in one of his discourses on beards, relates, that after the council of Trent, several ecclesiastics, being obliged to shave, were some time after seized with a violent tooth ach. I may add to these authorities what I have been told by very credible persons. A German gentleman, having been a long time tormented with a violent pain in his teeth, was advised to let his
