[Illustration: Figs. 119 and 120] 1. Let any one chalk the line fig. [119 L p. II], on a flat surface, beginning at either end, and he will move his hand and arm in a beautiful direction, but if he chalks the same sort of line on an ogee-moulding of a foot or two in breadth, as the dotted line on figure [120 L p. II], his hand must move in that more beautiful direction, which is distinguished by the name of grace; and according to the quantity given to those lines, greatness will be added to grace, and the movement will be more or less noble. Gentle movements of this sort thus understood, may be made at any time and any where, which by frequent repetitions will become so familiar to the parts so exercised, that on proper occasion they make them as it were of their own accord. The pleasing effect of this manner of moving the hand, is seen when a snuff-box, or fan is presented gracefully or genteely to a lady, both in the hand moving forward and in its return, but care must be taken that the line of movement be but gentle, as No. 3, fig. 49, plate I, and not too S-like and twirling, as No. 7 in the same figure: which excess would be affected and ridiculous. [Illustration: Fig. 49] Daily practising these movements with the hands and arms, as also with such other parts of the body as are capable of them, will in a short time render the whole person graceful and easy at pleasure. 2. As to the motions of the _head_; the awe most children are in before strangers, till they come to a certain age, is the cause of their dropping and drawing their chins down into their breasts, and looking under their foreheads, as if conscious of their weakness, or of something wrong about them. To prevent this aukward shyness, parents and tutors are continually teasing them to hold up their heads, which if they get them to do it is with difficulty, and of course in so constrain'd a manner that it gives the children pain, so that they naturally take all opportunities of easing themselves by holding down their heads; which posture would be full as uneasy to them were it not a relief from restraint: and there is another misfortune in holding down the head, that it is apt to make them bend too much in the back; when this happens to be the case, they then have recourse to steel-collars, and other iron-machines; all which shacklings are repugnant to nature, and may make the body grow crooked. This daily fatigue both to the children and the parents may be avoided, and an ugly habit prevented, by only (at a proper age) fastening a ribbon to a quantity of platted hair, or to the cap, so as it may be kept fast in its place, and the other end to the back of the coat, as fig. [121 L p. II], of such a length as may prevent them drawing their chins into their necks; which ribbon will always leave the head at liberty to move in any direction but this aukward one they are so apt to fall into.
