50. Apoplexy; paralysis. 51. Ophthalmia; skin diseases; cough; oppression of the chest. 52. Dysmenorrhea; affections of the testicles; costal pains. 53. Ophthalmia; dysmenorrhea; amenorrhea; skin eruptions. Such therapy, detached entirely from the actual requirements of the case and based only upon observation of the sky, was bound to be attended with the most unfortunate results. The suffering public was frequently but little cheered by the assistance of its physicians, and often felt the desire to find out what another physician could do. It appears that such a condition occurred quite frequently, for Ptolemy, in number 57 of his “Centiloquium,” gives special directions under what astral conditions such a change of physician could take place. He says: “_Cum septimum locum atque ejus dominum in ægritudine afflictum videris, medicum mutato._” It appears certain, accordingly, that a general change of physicians was inaugurated by the public so soon as the above conjunction was noted in the sky. Those who desired to be very careful in the choice of their physician did not change only when the conjunction of the stars recommended it as advisable, but they also attempted to ascertain the horoscope of the newly chosen medical adviser, for medical wisdom was found in greatest abundance in a man whose aspects showed a certain form. “_Perfectus medicus erit, cui Mars et Venus fuerint in sexta_,” says Almansor. This condition of _Astrologia Medica_ was such as to weigh like an oppressive nightmare upon mankind, not only for centuries but for thousands of years, and in this way medical superstition has slaughtered more human beings than the most bloody wars ever did.
