Lucius Quintus Cincinnatus Lamar, New York Company v. Winter's Admistrator…
“ While it may be admitted, as a general rule, that the contract between the passenger and the railroad company is made up of the ticket which he purchases and the rules and regulations of the road, yet it does not follow that parol evidence of what was said between the passenger and the ticket seller from whom he purchased his ticket, at the time of such purchase, is inadmissible, as going to make up the contract of carriage, and forming a part of it. ”
