26 THE GROWTH OF TRUTH 



states in a manuscript introductory lecture in the College 

 library ' I deliver nothing I have not seen and observed 

 myself 'he could not add with him, ' I am not a reader 

 of books.' Nearly one hundred references to some 

 twenty authors occur in the manuscript of the thorax, 

 or, as he calls it, the ' parlour ' lecture. 



It is a great pity that we have no contemporary 

 account of the impression on such men as Mayerne or 

 Reid of the new doctrines, for which we have the 

 author's statement that they were taught annually and

 appreciated ; and in a man of such good parts as Harvey 

 would in pity be condoned, just as we overlook the 

 mild intellectual vagaries of our friends. 



Bootless to ask, impossible to answer, is the question 

 why Harvey delayed for twelve years the publication
