"It would have been easy for our illustrious colleague to have woven the whole of this web from materials of his own; but to escape the charge of envy he has rather chosen to take Aristotle and Fabricius of Aquapendente as his guides, and to appear as contributing but his portion to the general fabric. Of him whose virtue, candour, and genius are so well known to you all I shall say no more, lest I should seem to praise to his face one whose singular worth has exalted him beyond the reach of all praise. Of myself I shall only say that I have done no more than perform the midwife's office in this business, ushering into the light this product of our colleague's genius as you see it, consummate and complete, but long delayed and fearing perchance some envious blast; in other words, I have overlooked the press; and as our author writes a hand which no one without practice can easily read[8] (a thing that is common among our men of letters), I have taken some pains to prevent the printer committing any very grave blunders through this--a point which I observe not to have been sufficiently attended to in the small work[9] of his which lately appeared. Here then, my learned friends, you have the cause of my addressing you at this time, viz., that you may know that our Harvey presents an offering to the benefit of the republic of letters, to your honour, to his own eternal fame. "Farewell, and prosper "GEORGE ENT."
