There is an entry in Day By Day for May 17, 1788 that has me 
puzzled:*May 17 Thursday* – *Frederick J. Hall** for Webster & 
Co.* wrote to Sam: “Your favor received, also the watch. We will pay the 
Burton bill, the bill for composition and electrotyping on the Burton 
book, and also send you invoice for the watch. We have forwarded a copy 
of ‘The Library of Humor’.” Other finances were discussed [MTP]. /Note/: 
*Richard E. Burton*.

Who is this Burton and what book did he write?  This cannot be Richard 
F. Burton, who figures so much in my treatment of Sam Clemens' travels 
to Carson City.
