SYNONYMS 



In order to make the above list as accurate and up-to-date as possible, duplicate 

 copies of the first rough draft were sent to all of the American writers on this sub- 

 ject for corrections, additions, subtractions, comments, etc. At this time I have 

 received returned copies from several, but have found it necessary to go ahead with 

 the editing before all of the first copies are returned. All corrections in the future, 

 however, shall be added as supplemental work, so that the present work shall con- 

 tinue to grow and be of more value as the various points are cleared up. I am 

 especially indebted to Prof. O. W. Oestlund for the large list of synonymous names 

 which he so thoroughly worked up. xVlso to Prof. H. F. Wilson, Miss Edith Patch, 

 Prof. C. F. Baker, J. T. Monell, and W. M. Davidson.
