[If one declares,] “This [animal] is hereby a temurah for an olah, a temurah for a shelamim,” it is thereby a temurah for an olah; [these are] the words of R’ Meir. R’ Yose said: If he intended to [say] this from the outset, since it is impossible to utter two designa- tions simultaneously, his declarations stand. However, if after he declared, “This is hereby a temurah for an olah,” he [then] reconsidered and declared “a temurah for a shelamim,” it is a temurah for an olah.
