PEATE Vv. 
Fig. 1. Aerolite, Long Island, Phillips Co., Kansas. This was probably a single 
mass, broken in pieces by striking on a ledge as it fell. Four of the largest 
of the fragments have been joined together along the planes of original 
fracture, giving the mass shown in the-figure. The other fragments occu- 
pied the place of the pedestal. The white coating shown over a portion 
of the surface was undoubtedly formed subsequent to the fall of the stone. 
The true crust has the appearance of an earthenware glaze. 
Fig. 2. Seven individual derolites, Leland, Winnebago Co., Iowa, showing crust, 
pitted surface and interior.
