“ It presents the question, whether parol evidence should have been received, to vary, alter, or contradict that which appears on the face of the bill of exchange.
When the operation of a contract is clearly settled by general principles of law, it is taken to be the true sense of the contracting parties. ”

“ Dunn, (6 Peters, 56,) this court have declared 'that there is no rule better settled or more salutary in its application them that which precludes the admission of parol evidence to contradict or substantially vary the legal import of a written agreement.' The case of Brochmore v. Davenport, 14 Texas Rep., 602, a case precisely similar to the present, adopts the same rule. The case of Robishat v. Folse, 11 Louisiana, and of Barthet v. Estebene, 5 Ann. Rep., 315, and several others, acknowledge the same doctrine, thereby overruling some early cases in Louisiana which had departed from it. ”

“ La. R., 57, and Robertson v. Nott, 2 Martin, N. S., 122, have not since been followed, even in Louisiana, but substantially, though tacitly, overruled. (Police Jury v. Haw, 2 La. R. 42; Robechot v. Folse, 11 ib., 133; Arnous v. Davern, 18 ib., 42; Barthete v. Estebene, 5 La. Ann. R., 315; Gosserband v. Lacour, 8 ib., 75; Williams v. Flood, 11 ib., 113.)
2. That it is the lex fori, and not the lex loci contractus, which governs the question, according to the decisions in Louisiana herself. (Shewell v. Raguet, 17 La. R., 457.)
Mr. Justice GRIER delivered the opinion of the court. ”
