Thirdly, Here is the right way for thee to begin at the study of Physic, if thou art minded to begin at the right end, for here thou hast the reason of the whole art. I wrote before in certain Astrological Lectures, which I read, and printed, intituled, _Astrological Judgment of Diseases_, what planet caused (as a second cause) every disease, how it might be found out what planet caused it; here thou hast what planet cures it by _Sympathy_ and _Antipathy_; and this brings me to my last promise, _viz._ _Instructions for the right use of the book._ And herein let me premise a word or two. The Herbs, Plants, &c. are now in the book appropriated to their proper planets. Therefore, First, Consider what planet causeth the disease; that thou mayest find it in my aforesaid Judgment of Diseases. Secondly, Consider what part of the body is afflicted by the disease, and whether it lies in the flesh, or blood, or bones, or ventricles. Thirdly, Consider by what planet the afflicted part of the body is governed: that my Judgment of Diseases will inform you also. Fourthly, You may oppose diseases by Herbs of the planet, opposite to the planet that causes them: as diseases of _Jupiter_ by herbs of _Mercury_, and the contrary; diseases of the _Luminaries_ by the herbs of _Saturn_, and the contrary; diseases of _Mars_ by herbs of _Venus_, and the contrary. Fifthly, There is a way to cure diseases sometimes by _Sympathy_, and so every planet cures his own disease; as the _Sun_ and _Moon_ by their Herbs cure the Eyes, _Saturn_ the Spleen, _Jupiter_ the liver, _Mars_ the Gall and diseases of choler, and _Venus_ diseases in the instruments of Generation. NICH. CULPEPER. From my House in Spitalfields, next door to the Red Lion, _September 5, 1653_. TO HIS DEAREST CONSORT MRS. ALICE CULPEPER. MY DEAREST, THE works that I have published to the world (though envied by some illiterate physicians) have merited such just applause, that thou mayest be confident in proceeding to publish anything I leave thee, especially this master-piece: assuring my friends and countrymen, that they will receive as much benefit by this, as by my _Dispensatory_, and that incomparable piece called, _Semiotica Uranica_ enlarged, and _English Physician_. These are the choicest secrets, which I have had many years locked up in my own breast. I gained them by my constant practice, and by them I maintained a continual reputation in the world, and I doubt not but the world will honour thee for divulging them; and my fame shall continue and increase thereby, though the period of my Life and Studies be at hand, and I must now bid all things under the sun farewell. Farewell, my dear wife and child; farewell, Arts and Sciences, which I so dearly loved; farewell, all worldly glories; adieu, readers, NICHOLAS CULPEPER. * * * * *
