 delighted to honour, was thus as truly the

 primarily even as surgeon-in-chief : his place 

 in history, immortal though it be, is also 

 humble, humbler even than that of the 

 plebeian branch of the profession, the bar-

 is "the shepherd with his tarbox by his side"; 

 more simply still, since full shepherd-craft 

 is far beyond his ken, he is the "tar-boy," 

 who waits upon the shepherd, ready to put 

 on his dab of antiseptic wherever needed.
