Abstract
SEVERAL hypotheses have been advanced to explain the peculiar circumstances associated with the fall of the Tunguska Meteor on June 30, 1908, in Siberia (lat. 60° 55′ N., long. 101° 57′ E.). An exhaustive description of the phenomena is given by Krinov1. Especially puzzling is the apparent absence of a meteoric crater, but Krinov2 does report some recent analyses of soil in the region which show iiickeliferous iron and silicate globules.
