MOTION OF THE HEART AND BLOOD 



None age so perfectly that subtle change 

 With time or custom seems not new nor strange; 

 What's once believed is now denied, and what 

 Was honored once now suffers in exchange. 



So may it now be regarding the motion of the heart. 

 The path is open for others, starting here, to progress 

 more fortunately and more correctly under a more 

 propitious genius. 



lines may be excused on the plea that it places the context in the ap- 

 propriately tolerant and resigned verse-form made famous by Edward 

 FitzGerald. Dr. Willis, in his 1847 Harvey, translates the lines in the 

 classical tradition: 



For never yet hath any one attained 

 To such perfection, but that time, and place. 

 And use, have brought addition to his knowledge; 

 Or made correction, or admonished him 

 That he was ignorant of much which he 

 Had thought he knew; or led him to reject 

 What he had once esteemed of highest price. 

 George Colman's translation is quoted by T. B. Harbottle, Dictionary 

 of Quotations (Classical), London and New York, 1897.
