 bj me, years before his voice was heard upon this subject, 

 has been proved in the foregoing pages. In point of fact, 

 if he had preceded me instead of following me, and if my 

 desire had been to incorporate his wishes in my words, 

 I could not have accomplished this more completely. It 

 is possible, moreover, to draw the coincident lines still

With one special utterance of Professor Yirchow his 

 translator connects me by name. "I have no objection," 

 observes the Professor, "to your saying that atoms of car-
