Only one document is known to exist for the case of Biggs v. Baker, and it reveals little about the suit. It is clear that Lincoln, Stephen T. Logan, and Henry Eddy represent plaintiff Thompson H. Biggs, who is suing defendant Ezra Baker. On this day, Lincoln writes to Eddy and encloses a letter from Biggs. Lincoln informs Eddy that the attorneys are not sure whether or not "the process has been served as yet, on Dr. Baker." Lincoln concludes by asking Eddy to "write to Mr. Biggs and to us on any point that suggests itself to you as proper." Lincoln does not reveal the court in which the case is being tried, nor does he state the nature of the dispute. Abraham Lincoln to Henry Eddy (copy), 23 June 1842, Biggs v. Baker, copy files, IHi, Springfield, IL; CW 10:6-7.
