PLATE II. 



Fig. 1. Portion of section shown in Plate I, Figure 2, magnified 14 diameters. 

 The broad bands are the kamacite of Reichenbach and are bordered by 

 narrow ones of taenite. The unindividualized ground-mass enclosed 

 within the rhombs, is the so-called plessite, but this can be seen to pass 

 imperceptibly into the slender parallel bands called, by J. Lawrence 

 Smith, Laphamite markings. 



Fig. 2. Another portion of the same section magnified 14 diameters. The etching 

 figures are similar to those shown in Fig. 1, and there is also shown an 

 inclusion of troilite, bordered by a layer of kamacite.
