350 J. L. Smith—Dickson County Meteorite. 
which, although it is forty years since it fell, has not been seen 
by a half dozen scientific men. 
This meteorite fell during the day-time, in a field where 
several persons were at work, fnghtening a horse attached to 
a plough, who ran wildly about the field dragging the plough 
after him. It struck the ground at the root of a large oak, 
descending at rather an acute angle, and burying itself in the 
roots of the tree. The sky was cloudlesy and a noise was 
heard preceded by a vivid light. Other particulars connected 
with its fall, as well as a description of its size and form, have 
been already published by Prof. Troost. It is of an elongated 
idney shape and remarkably symmetrical form, the metal 
being bright and almost polished on many parts of the surface, 
and it has remained in this condition ever since it was dis- 
rated from each other by an ap- 
parently semi-fused or slaggy 
matter. These lamin running 
octahedrons. The cebscie 
nying cut will better exhibit 
these lines very much mag- 
ge eset nified. ; 
Another noteworthy fact in connection with this iron (which 
is soft and tough) is that when cut and polished, it will resist 
the tarnishing effects of the ordinary vapors of the laboratory, 
as I have pieces which have been thus exposed for several 
months. 
By the agency of heat or acid the Widmannstittian figures 
are developed with exquisite beauty, not equalled except by 
three or four known meteoric irons. In connection with these 
figures I will call attention to the delicate — lines inside
