The approximate composition of the mass was calculated from the weights found 
by extracting all the metallic portion with an electro-magnet, and the analysis of the resi- 
due, all the sulphur being calculated as troiiite. Analyses Nos. 1, 2, 3, 4 and 5 were 
made on the silicate portion containing the troilite, from which the metallic part had been 
removed, and No. 1 is that of the actual portion soluble in hydrochloric acid. No. 2 is 
the same analysis from which all the sulphur and 8.89% of iron (equal to 11.43% Fe O) 
have been deducted. No. 3 is analysis No, 2 calculated to 100%. No. 4 is the analysis 
of the portion insoluble in hydrochloric acid. No. 5 is analysis No, 4 calculated 
to 100%.

Although there is no striking resemblance between the analysis of 
the Dojia Inez by Mr. Davison and the Llano del Inca by. Mr. Eakins 
I am inclined to think they are parts of the same “ fall.”’ The difference 
in the analysis is not greater than might perhaps be expected from 
different parts of the same piece. A nodule of iron about one-quarter 
inch in diameter was found in one of the fragments of the Llano del 
Inca, which upon being etched shows markings apparently ideutical 
with those on the Dofia Inez. The difference in the weathering of the 
pieces of the two may perhaps be accounted for by different conditions 
of exposure. 
The breaking up of both meteorites, particularly the Llano del 
Inca into such small, solid, angular fragments with sharp corners, none 
of which show signs of a crust, can hardly be accounted for by decom- 
position, but is doubtless the work of man—probably mistaking the 
nickeliferous iron for silver, or curious to see what could be found. 
Perhaps the breaking up of the Llano del Inca is more recent than that 
of the Dona Inez. 
_ The information at hand is not sufficiently definite to determine 
the distance between these two finds, but it is probably not more than 
50 to 75 miles and possibly less. 
Dr. M. E. Wadsworth, Director of the Michigan Mining School 
and State Geologist, has made an examination of these meteorites, and 
has furnished the following description :

Llano del Inca Meteorite. 
Macroscopically this is a grayish brown rock composed of feldspar and other silicates 
with some iron, etc. On this specimen no sign of the usual crust of fusion could be seen 
such as is usual on meteoric stones. Except for the metallic iron, the stone closely 
resembles some terrestrial gabbros and diabases.
