Those who are intrusted with the Education of Youth, may also be supposed sufficiently intelligent to take some Part in this Work; and I am satisfied that much Good might result from their undertaking it. I heartily wish, they would not only study to _distinguish the Distemper_ (in which the principal, but by no means an insuperable Difficulty consists; and to which I hope I have considerably put them in the Way) but I would have them learn also the Manner of applying Remedies. Many of them have; I have known some who bleed, and who have given Glysters very expertly. This however all may easily learn; and perhaps it would not be imprudent, if the Art of bleeding well and safely were reckoned a necessary Qualification, when they are examined for their Employment. These Faculties, that of estimating the Degree of a Fever, and how to apply and to dress Blisters, may be of great Use within the Neighbourhood of their Residence. Their Schools, which are not frequently over-crouded, employ but a few of their daily Hours; the greater part of them have no Land to cultivate; and to what better Use can they apply their Leisure, than to the Assistance and Comfort of the Sick? The moderate Price of their Service may be so ascertained, as to incommode no Person; and this little Emolument might render their own Situation the more agreeable: besides which, these little Avocations might prevent their being drawn aside sometimes, by Reason of their Facility and frequent Leisure, so as to contract a Habit of drinking too often. Another Benefit would also accrue from accustoming them to this kind of Practice, which is, that being habituated to the Care of sick People, and having frequent Occasions to write, they would be the better qualify'd, in difficult Cases, to advise with those, who were thought further necessary to be consulted. Doubtless, even among Labourers, there may be many, for some such I have known, who being endued with good natural Sense and Judgment, and abounding with Benevolence, will read this Book with Attention, and eagerly extend the Maxims and the Methods it recommends. And finally I hope that many Surgeons, who are spread about the Country, and who practice Physic in their Neighbourhood, will peruse it; will carefully enter into the Principles established in it, and will conform to its Directions; tho' a little different perhaps from such as they may have hitherto practiced. They will perceive a Man may learn at any Age, and of any Person; and it may be hoped they will not think it too much Trouble to reform some of their Notions in a Science, which is not properly within their Profession (and to the Study of which they were never instituted) by those of a Person, who is solely employed in it, and who has had many Assistances of which they are deprived. Midwives may also find their Attendance more efficacious, as soon as they are thoroughly disposed to be better informed.
