To Peter Zinn 
Dear Sir Sep. 6. 1859
Yours of the 2nd. in relation to my appearing at Cincinnati in behalf of the Opposition is received. I already had a similar letter from Mr. W. T. Bascom, Secretary of the Republican State central committee at Columbus, which I answer to-day.  You are in correspondence with him, and will learn all from him. I shall try to speak at Columbus and Cincinnati; but can not do more. Yours truly A. LINCOLN
 ALS, owned by William P. Zinn, Columbus, Ohio. Peter Zinn was an attorney at Delhi, Ohio, and a member of the Republican state central committee.
 Lincoln's letter to William T. Bascom is presumably not extant, but Bascom's letter to Lincoln, September 9, 1859 (DLC-RTL), mentions receiving it. Also a member of the Republican state central committee of Ohio, Bascom was an editor of the Ohio State Journal.
