"Making many difficulties at first, urging among other things that his work must be held imperfect, as not containing his investigations on the generation of insects; I nevertheless prevailed at length, and he said to me, 'I intrust these papers to your care with full authority either speedily to commit them to the press, or to suppress them till some future time.' Having returned him many thanks, I bade him adieu and took my leave, feeling like another Jason laden with the golden fleece. On returning home I forthwith proceeded to examine my prize in all its parts, and could not but wonder with myself that such a treasure should have lain so long concealed; and that whilst others produce their trifles and emptiness with much ado, their messes twice, aye, an hundred times, heated up, our Harvey should set so little store by his admirable observations. And indeed so often as he has sent forth any of his discoveries to the world, he has not comported himself like those who, when they publish, would have us believe that an oak had spoken, and that they had merited the rarest honours--a draught of hen's milk at the least. Our Harvey rather seems as though discovery were natural, a matter of ordinary business; though he may nevertheless have expended infinite labour and study on his works. And we have evidence of his singular candour in this, that he never hostilely attacks any previous writer, but ever courteously sets down and comments upon the opinions of each; and indeed he is wont to say that it is argument of an indifferent cause when it is contended for with violence and distemper, and that truth scarce wants an advocate.
