The practice then fell into the hands of laymen, although priests, still regretting the advantages that it formerly had yielded them, were consulted in their convents or houses; and when patients could not visit them without exposing them to clerical censure, they asserted their ability to cure diseases by the mere inspection of the patient's dejections; and so much faith was reposed in this filthy practice, that Henry II. decreed that upon the complaints of the heirs of persons who died through the fault of their physicians, the latter should suffer capital punishment, as having been the cause of their patient's death, unless they had scientifically examined what was submitted to their investigation by the deceased's relatives or domestics: and then proceeded to prescribe for the malady. Unable to quit their cloisters, in surgical cases, which could not be so easily cured at a distance, sooner than lose the emoluments of the profession, they sent their servants, or rather the barbers of the community, who shaved, and bled, and drew teeth in their neighbourhood ever since the clergy could no longer perform these operations, on the plea of the maxim "_Ecclesia abhorret a sanguine_;" bleeding and tooth-drawing being, I believe, the only cases where this maxim was noticed. From this circumstance arose the barber craft or barber-surgeons. These practitioners, from their various avocations, were necessarily dexterous; for, in addition to the skill required for good shaving, tonsurating the crowns of clerical heads was a delicate operation; and it was about this period that Pope Alexander III. revised the canon issued by the synod of Carthage respecting the tonsure of the clergy. Surgery being thus degraded, the separation between its practice and that of medicine became unavoidable, and the two branches were formally made distinct by bulls of Boniface VI. and Clement V.
