panying cut. The surface is unusually smooth, showing only a few 
shallow pittings. The two largest diameters are 10 and 5% inches 
(25x14 centimeters) and the weight was 14 lbs. 7% oz., or a trifle over 
6% kilos. 
Although the surface of this iron is unusually interesting the inter- 
ior proves to be still more so. The etched sections show that the mass 
has been subjected to fracture and dislocation, resulting in a distinct 
and unquestionable “faulting” of the Widmanstitten figures, and of 
the troilite. Most of these faults are so small and faint that they can- 
not be reproduced in an illustration, but are clearly seen with a pocket 
lens. The accompanying cut of one of the etched sections, reproduced 
by photographic process, shows three of these lines of faulting. These 
are the especially interesting feature of this meteorite, and, as far as I

am aware, are the first faults noted in an iron meteorite. The novelty 
of this phenomenon, and the exceeding toughness of meteoric iron, 
making a sharp fault seem almost an impossibility, require that the 
evidence of such a fault should be clear and conclusive before its 
acceptance as a fact. And such is fortunately the case. The largest 
fault is seen in successive sections for two and one quarter inches, or as 
far as the iron has been cut, and apparently extends the entire length 
of the mass. The throw of this fault is nearly one-eight of an inch 
3m.m.). Careful examination reveals some crushing and branching 
along this line. Other parts of this section, and other sections, show 
small fractures with slight displacement. These faults are clearly not 
the result of the impact of its fall, but are a part of its earlier history. 
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
