Stanley Matthews, Dewey v. West Fairmont Gas Coal Company…
“ The object of the test evidently was to determine, on the part of the complainants for themselves, whether they were willing to run the risk of using coke to be manufactured by the coal company from the slack of their mines at the price offered. The coke which was subsequently furnished under the contract was used by the complainants, and paid for according to the contract, without objection, except as to a lot furnished in December, 1872, which was complained of as being inferior. ”
