IV PREFATORY NOTE. 



plates, in many cases with his own hands retouching photographs or correcting 

 minor errors in drawing. After that, it has been his duty to read both the galley- 

 and page-proofs as they have come to his hands, and finally to index the different 

 volumes before having them bound up in permanent form. It is needless to say 

 that this work has necessitated constant labor and unremitting attention to minute 

 details. The Editor does not indulge in these observations at this point for 

 the purpose of calling attention to the part which he has necessarily been com- 

 pelled to take in this work, but for the purpose of expressing to the authors whose 

 productions have passed through his hands the hope that they have not found 

 occasion to quarrel with his activities. In the performance of his editorial duties 

 the Editor has kept before himself as his constant aim the revelation of the exact 

 thought of his friends, the authors, in the form of correct English. He has always 

 striven to express the exact meaning intended to be conveyed by the writer, 

 even when he has seen fit (as has frequently been the case) to radically modify the 

 verbiage employed, to transpose words and paragraphs, or to eliminate unnecessary 

 repetition.
