PLATES 



The first three plates (A-C) present, for purposes of comparison, 

 typical iron-carbon structures in artificial irons. The other plates 

 (1-78) illustrate 97 meteoric irons, the names of which are indexed 

 below. All specimens Olustrated are from the author's collection 

 unless otherwise indicated. 



In engraving the plates the size of the photographs has been 

 reduced by 40 percent; thus an original magnification of 100 diameters 

 appears as 60, one of 2,000 as 1,200, etc. 



All the original photographs, and many others, of the u'ons here 

 illustrated are in a collection of about 1,300 photomicrographs of 

 meteoric irons bound in five volumes, with descriptive and interpre- 

 tive data on each, deposited in the United States National Museum, 

 where they may be conveniently consulted. The negatives of all of 

 them are also on file in the Museum, where prints from any of them 

 may be obtained.
