Abstract
The discovery of human footprints in volcanic rocks near the shore of Lake Managua, Nicaragua, under circumstances which seemed to assign them a remote antiquity, has been announced for several years. We owe thanks especially to Dr. Earl Flint, of Rivas, Nicaragua, for information about this discovery, and for sending several specimens to the United States. Four of these are in the Peabody Museum of Archaeology, Cambridge, and recently I have myself received one from Dr. Flint, together with several letters describing the locality. The possession of this material has induced me to present, along with its description, a general review of the subject.
