226 E. E. Howell — Meteorite from Puquios, Chili. 



throw of this fault is nearly -§- of ail inch (3 mm ). Careful ex- 

 amination reveals some crushing and branching along this line,

and other parts of this section and other sections show small 

 fractures with slight displacements. 



These faults are clearly not produced by the impact of its 

 fall upon the earth, but are a part of its earlier history, and in 

 the light of some experiments made two years ago with Toluca 

 iron I would suggest the probability that they were made when 

 the iron was very hot — perhaps in its passage near the sun. I 

 found that a piece of Toluca iron, although very tough when 

 cold would crumble under the hammer when heated to a white 

 heat. If we assume that the faulting of this meteorite took 

 place under similar conditions of heat it seems necessary also 

 to assume a contact with some other body. 



The Widmanstatten figures call for no special remarks as 

 they are sufficiently shown in the illustration. Suffice it to 

 say that they are produced very readily with weak acid, that 

 the finer lines inside the figures are unusually well developed, 

 and are sometimes seen running parallel to the adjacent sides.
