There are yet some farther things relative to Health, which Parents must not disregard. Constitutions are so variously formed, that the same Employment which suits one Child, will not another. If one is closely confined to Study it will impair his Health, and either shorten his Days, or make him miserable: if another is engaged in a laborious Business, his tender Frame, perhaps, sinks under it: if a third is indulged in an easy Occupation, where Action would have suited his Frame, he becomes indolent, insipid, and infirm, a Burden to himself and others. Lastly, there are Occupations in Life whose Fumes are known to affect us; and some Regard should be had even to these, since the Health of our Children is concerned: not that I here recommend the Observance of each Nicety, or would have Children afraid of every Vapour that rises around them, or of every Employment that is accompanied with Labour: no; that would be making Life too painful, and fix in our Children an unmanly Timorousness, which would make them puny, frivolous or hurtful; and would be swerving from the Opinion of the greatest Men that have studied and wrote on these Subjects: For _Hippocrates_, _Celsus_, and all those who were best acquainted with what Physicians call the Non-naturals, maintain, that, besides Temperance and Air, Exercise, and that too of the most laborious Kind, particularly Husbandry, is indispensably necessary for Health. What then in general I here advise, is, that Parents, in settling their Children, have an Eye to their Health, at the same time that they study their Interest and Prosperity. Having thus with real Pains, and an unfeigned Desire to promote the Welfare of Mankind, pointed out the general Means of preserving Health, and, I hope, set in a true Light those Errors which usually tend to impair or destroy it; if Parents seriously adhere to the one, and avoid the other, their Children will receive many and great Advantages therefrom. It may be urged, that the Treatment which suits one Child will not another; and that general Rules are always subject to particular Exceptions: I grant it. Still this does not justify those Parents who submit to no Rules at all. I have said before, that all Laws give Parents the sole Power of governing their Children; I may also maintain that the same Laws oblige them to do every thing to promote their Welfare. Those who are unacquainted with the Duty of a Parent, must learn; those who know, must practice. Let this Admonition then rouse the Attention of Parents; and let these Precepts serve as the Foundation, whereon to build the solid Health of their Children. The Constitution is like the Countenance, somewhat different in every one; where therefore any Deviations from Rule are the Effect of Judgment, I sincerely applaud them; and where any Principle here laid down proves erroneous, I chearfully submit to the Removal of it.
