 disservice could be done to a man of science, than to overstate his 

 claims : such overstatement is sure to recoil to the disadvantage of 

 him in whose interest it is made. But when Mayer's opportunities, 

 achievements, and fate are taken into account, I do not think that I 

 shall be deeply blamed for attempting to place him in that honourable
