928 A. LIVERSIDGE, 
holes are given on the plates, as it is not possible to judge 
of their depths from the illustrations. 
Plate 13, shows the internal structure of the main mass 
of the meteorite after the removal of the seventh slice, 
reduced to one half the natural size. It shows two well 
marked nodules, one indicated by the letters a.a. is more 
or less pentagonal in outline, and contains a central nucleus 
probably of kamacite and other smaller nodules; the 
second, marked b.b., is almost circular in section. 
Plate 14, is from an enlarged photograph (2 diameters) 
of the two nodules a.a. and b.b. The spherical nodule is 
shown to be fissured roughly into quadrants, and the usual 
investing films of lustrous kamacite are clearly shown. 
There arenumerous veryremarkable long narrow bright lines 
of teenite, they are also visible in the other photographs 
but not so distinctly. When copper sulphate is used for 
etching, these very fine lines are apt to be lost. It will be 
noticed that these fine lines cut across many of the larger 
crystals. Many more details are shown in the original 
photograph, and some can be seen in this plate by the use 
of alens. The dark crystals or portions of crystals are 
metallic looking (like the rest of the meteorite) before 
etching. . 
Plate 15. This represents the etched surface of the 
seventh slice reduced to one half the natural size. The 
nodules a.a. and b.b. do not extend into this, and it is not 
quite clear whether any portions of the crystals seen in 
Plate 13 are present in this section. 
Plate 16 represents the sixth slice reduced to ¢¢ of the 
natural size. The hole in the lower part is due to one of 
the cavities having been cut across. 
Plate 17 represents the fifth slice reduced to 2c. The 
comparatively large crystals of kamacite are arranged in 
remarkable parallel lines.
