Usage examples of "doctour".
And it shall be registred in the bookes of Doctours, that an Asse saved the life of a young maiden that was captive amongst Theeves : Thou shalt be numbred amongst the ancient miracles : wee beleeve that by like example of truth Phryxus saved himselfe from drowning upon the Ram, Arion escaped upon a Dolphin, and that Europa was delivered by the Bull.
The woman that slew the Maiden having lost the name of wife together with her faith, went to a traiterous Physician, who had killed a great many persons in his dayes and promised him fifty peeces of Gold, if he would give her a present poyson to kill her husband out of hand, but in presence of her Husband, she feined that it was necessary for him to receive a certaine kind of drink, which the Maisters and Doctours of Physicke doe call a sacred Potion, to the intent he might purge Choller and scoure the interiour parts of his body.
