David Josiah Brewer,
Lonergan v. Buford — Opinion of the Court
“ Suppose a written contract is made for the sale of a herd of cattle at $30 a head, excepting therefrom all yearling steers. Would not parol testimony of the number of yearling steers in the herd be necessary in order to show the number of cattle sold, and the aggregate sum to be paid? Evidence that the herd contained 1,000 head would not end the question, and parol testimony of the number of yearling steers would not be evidence contradicting the contract. ”
