There is a further question whether the evidence is sufficient to
establish a cause of action under sec. 19 (2). In Benjamin on Sale,
7th ed. (1931), at pp. 635, 636, the learned author says : - " At
common law, the most usual instance of a contract of sale of goods
"by description' was an agreement to sell unascertained or future
goods of a certain description i.e., kind or class . . . A specific
chattel could also be sold by description at common law. Here,
however, a distinction existed. Unascertained goods can have no
description but what is given them by the contract, but a specific
chattel had also a physical identity, either corporeally present in

then arises whether the buyer bought simply the particular thing
which he saw or identified, or whether he bought it only on condition
that it conformed to the description given. A buyer might, of course,
expressly stipulate that he had bought only on such a condition ; but
otherwise his intention had to be discovered from the circumstances 3
and, as a general rule, a contract for the sale of a specific article was
a contract for that article as it was. The property passed by the
contract, and any superadded description. was either a mere repre-
