Abstract
The publication of the paper on the Aftonian Mammalian Fauna, in the Bulletin of the Geological Society of America, volume XX, pages 341-356, has very naturally elicited a number of questions which, however, bear chiefly on two points: First, are we certain as to the precise age of the gravels? And second, are we certain that the mammalian remains described may not be older than the Aftonian?
