Comparing Smith’s analyses of Santa Rosa and the Butcher 
irons with the Maverick County as given by Hidden, it will be 
seen at once that, if Smith could conclude from the similarity in 
composition of the Santa Rosa and Butcher irons that they be- 
longed to one fall, there appears no reason for considering that 
the Maverick County has a new composition, as it agrees more 
closely with the Coahuila.analyses than they do with each other.

Furthermore, Mr. Hidden speaks of Smith’s having compared 
the etched surface of the Coahuila iron with that of the Brau- 
nau. This comparison was made because the Braunau was the 
nearest iron at that time to compare it with, though differing 
widely from the Coahuila. Mr. Hidden’s description of the 
etched surface of the Maverick County iron applies most per- 
fectly to that of the Coahuila iron, particularly the appearance 
of two sets of fine parallel lines, which become obliterated by 
the continued action of the acid. ‘That these lines crossed at 
angles of 70° and 110° of course means nothing when the surface 
was cut at random. (This Journal, Oct. 1886, p. 284-308.) 
The accompanying plate printed directly from a specimen 
of the Butcher iron will be seen to be wonderfully like fig. 3 
in Mr. Hidden’s paper, already referred to, and this appearance 
is utterly different from any other known iron. 
Then he further speaks of the smooth surface and regular 
form of the Maverick County iron precluding its being part of 
the Coahuila fall; but his diagrams of the Maverick County 
iron might be taken for almost any one of the many Coahuila
