But for diet to auoide inward daungers, and clothing to auert outward iniuries, and all such preuentions, as are not proper to teachers, though in communitie more proper then to any common man: I set them ouer to parentes, and other well willers, which will see to them, that they faile not in those thinges: and if they do, will fly to Physicians, by their helpe to salue that, which themselues may forsee. For exercises I will deale, which to commend more then they will commend them selues, when I shall shew both what they be, and the particular profites of euery one of them, which I chuse from the rest, were me thinke verie needlesse, and cheifly to me, which seeme sufficiently to praise them, in that I do place them among principles of prerogatiue. But as in the soule I did picke out certaine pointes, whervnto I applyed the training principles: so likewise in the bodie, may I not also seuer some certaine partes, whervnto my preceptes must principally be conformed? that shall not neede. For as in the soule the frute of traine doth better and make complete euen that which I tuched not, and so consequently the whole soule: so in the bodie, those exercises which seeme to be appointed for some speciall partes, bycause they stirre those partes most, do qualifie the whole bodie, and make it most actiue. Wherefore as there I did promise not to anatomise the soule, as neither dealing with Diuines nor Philosophers: so do I not here make profession to shew the anatomie of the bodie, as medling neither with Physicians nor Surgeans, otherwise then any of them foure can helpe me in exercise. To the which effect, and ende, I will onely cull out from whence I can, such speciall notes, as both Philosophers, and Phisicians do know to be most true, and both the learned, and vnlearned, will confesse to be for them: and such also, as the training maisters may easely both helpe, and encrease in their owne triall. For both reason, and rule, do alwaye commaunde, that the maister be by, when exercise is vsed, thorough whose ouerlooking the circunstance is kept, which helpeth to health, and the contrarie shunned, which in exercise doth harme. In the elder yeares, reason at the elbow must serue the student, as in these younger, the maisters preference helpes to direct the child.
