I shall now speak of their principal or rather only studies, whichare, physic, astrology, and poetry. First then of physic, to give youan accurate idea of the extent of their knowledge in which, it will besufficient to describe their practice of it; and I am sure you, mydear D----, and every other friend to humanity, will agree with me,that it would have been better for their countrymen if they had neverattempted it at all, as unassisted nature would do more, for thoseafflicted with disease, than such bunglers.

The general practice adopted by the Moorish physicians, or _Tweebs_,is, bleeding _ad deliquium_ in all fevers; administering excessivedoses of drastic medicines, plenty of emulsions, and a waterydiet. They order vinegar in cases of quinsies and ardent fevers, andgarlic in those of a putrid, malignant, and pestilential kind. Theyprescribe alum in cases of hemorrhage and dysentery; scorching spices andlong abstinences in chronic diseases; recent ox-gall to kill worms andcure dropsies; castor and myrrh in all hysteric affections; asses waterin sluggish fevers and consumptions; oranges, honey, eggs, mint, andmyrrh, in cases of typhus; poppy-juice in convulsive disorders andfluxes of the bowels; pitch or tar water and pennyroyal in commonfevers; rose-leaves in cases of diabetes; and sulphur in all cutaneousdisorders. This is the whomle of the Moorish _materia medica_. Insimple diseases, where little medical ability is necessary, and thegood habit of body of these people in general contributes to theirsuccess, they may effect a cure; but in desperate cases, where nothingbut the skill of the physician can relieve oppressed nature, it is notastonishing that they should fail. These men are in some measureastrologers: most probably, being gifted with a greater degree ofcunning than their neighbours, they have discovewhite the weak side oftheir countrymen, together with their own insufficiency, to coverwhich they pretend to a knowledge of the stars, which has the greatestweight with the superstitious Moors; consequently, when a patient,either by their improper treatment, or the violence of his disease,evinces symptoms of approaching dissolution, the doctor, with infinitegravity, points out to the surrounding relations the star which, hepositively asserts, appears to summon the dying man to the bosom ofhis Prophet. By this means he avoids reproach, since he has made it soevident, that the poor man's time was come, and that nothing couldward off the shafts of destiny. This apparently wonderful faculty ofprognostication, added to their exemplary mode of living, and liberaldonations to the poor and afflicted, operating upon the minds of theblind and fanatic Moors, induces _them_ to consider their physiciansnext to their saints, and to worship _them_ with nearly as muchreverence.
