At the same time I am not ignorant there have already been a few Books calculated for Country Patients, who are remote from Succour: but some of these, tho' published with a very good Purpose, produce a bad Effect. Of this kind are all Collections of Receipts or Remedies, without the least Description of the Disease; and of Course without just Directions for the Exhibition, or Application, of them. Such, for Example, is the famous Collection of Madam _Fouquet_, and some more in the same manner. Some others approach towards my Plan; but many of them have taken in too many Distempers, whence they are become too voluminous. Besides, they have not dwelt sufficiently upon the Signs of the Diseases; upon their Causes; the general Regimen in them, and the Mismanagement of them. Their Receipts are not generally as simple, and as easy to prepare, as they ought to be. In short, the greater Part of their Writers seem, as they advanced, to have grown tired of their melancholy Task, and to have hurried them out too expeditiously. There are but two of them, which I must name with Respect, and which being proposed on a Plan very like my own, are executed in a superior Manner, that merits the highest Acknowlegements of the Publick. One of these Writers is M. _Rosen_, first Physician of the Kingdom of _Sweden_; who, some Years since, employed his just Reputation to render the best Services to his Country Men. He has made them retrench from the Almanacs those ridiculous Tales; those extraordinary Adventures; those pernicious astrological Injunctions, which there, as well as here, answer no End, but that of keeping up Ignorance, Credulity, Superstition, and the falsest Prejudices on the interesting Articles of Health, of Diseases, and of Remedies. He has also taken Care to publish simple plain Treatises on the most popular Distempers; which he has substituted in the Place of the former Heap of Absurdities. These concise Works however, which appear annually in their Almanacs, are not yet translated from the _Swedish_, so that I was unqualified to make any Extracts from them. The other is the Baron _Van Swieten_, first Physician to their Imperial Majesties, who, about two Years since, has effected for the Use of the Army, what I now attempt for sick People in the Country. Though my Work was greatly advanced, when I first saw his, I have taken some Passages from it: and had our Plans been exactly alike, I should imagine I had done the Publick more Service by endeavouring to extend the Reading of his Book, than by publishing a new one. Nevertheless, as he is silent on many Articles, of which I have treated diffusively; as he has treated of many Distempers, which did not come within my Plan; and has said nothing of some others which I could not omit; our two Works, without entering into the Particulars of the superior Merit of the Baron's, are very different, with Regard to the Subject of the Diseases; tho' in such as
