“Denys, Denys, who taught you to think so ill of man?”

“Mine eyes, that are not to be gulled by what men say, seeing this many a year what they do, in all the lands I travel.”

The doctor with some address made use of these last words to escape the personal question. “I too have eyes as well as thou, and go not by tradition only, but by what I have seen, and not only seen, but done. I have healed as many men by bleeding as that interloping Arabist has killed for want of it. 'Twas but t'other day I healed one threatened with leprosy; I but bled him at the tip of the nose. I cured last year a quartan ague: how? bled its forefinger. Our cure lost his memory. I brought it him back on the point of my lance; I bled him behind the ear. I bled a dolt of a boy, and now he is the only one who can tell his right hand from his left in a whole family of idiots. When the plague was here years ago, no sham plague, such as empyrics proclaim every six years or so, but the good honest Byzantine pest, I blooded an alderman freely, and cauterized the symptomatic buboes, and so pulled him out of the grave; whereas our then chirurgeon, a most pernicious Arabist, caught it himself, and died of it, aha, calling on Rhazes, Avicenna, and Mahound, who, could they have come, had all perished as miserably as himself.”

“Oh, my poor ears,” sighed Gerard.

“And am I fallen so low that one of your presence and speech rejects my art and listens to a rude soldier, so far behind even his own miserable trade as to bear an arbalest, a worn-out invention, that German children shoot at pigeons with, but German soldiers mock at since ever arquebusses came and put them down?”

“You foul-mouthed old charlatan,” cried Denys, “the arbalest is shouldered by taller men than ever stood in Rhenish hose, and even now it kills as many more than your noisy, stinking arquebus, as the lancet does than all our toys together. Go to! He was no fool who first called you 'leeches.' Sang-sues! va!”

Gerard groaned. “By the holy virgin, I wish you were both at Jericho, bellowing.'

“Thank you comrade. Then I'll bark no more, but at need I'll bite. If he has a lance, I have a sword; if he bleeds you, I'll bleed him. The moment his lance pricks your skin, little one, my sword-hilt knocks against his ribs; I have said it.”

And Denys turned pale, folded his arms, and looked gloomy and dangerous.

Gerard sighed wearily. “Now, as all this is about me, give me leave to say a word.”
