236 A. LIVERSIDGE. 
The material of this meteorite rusts very quickly, so 
much so that it was difficult to procure photographs of the 
polished and etched sections before a brown film had formed, 
although various precautions were taken to prevent the 
rusting from taking place, but no exudation of iron salts 
was observed. 
After polishing the sections, it was found that etching 
with bromine water gave the most detail, after treatment 
with bromine the sections were well rinsed and placed in 
ammonia or caustic potash and then packed in quicklime, 
in other cases they were also immersed in strong spirit 
and dried quickly, some also were dried for a long period 
in a water oven and coated with collodion, but in spite of 
all the care exercised, they sooner or later became coated 
with a brown film of rust. 
The best results were obtained by keeping the sections 
in kerosene oil. This treatment will, of course, prevent 
the sections from being employed for the determination of 
carbonaceous matter and of occluded gases, but it was 
thought that the preservation of the sections was of more 
importance than the possibility of their being needed for 
those purposes. 
Seven parallel slices in all were cut off, and one side of 
each section was planed, polished, etched and photographed. 
The outer slices are quite small in area, as they are taken 
from the nodosities or projecting portions of the mass. 
The inner sections, of course gradually became larger, 
and had to be left thicker for fear they should break in 
the process of cutting; the process of cutting became very 
difficult and hard upon the saw with the increase in the 
areas of the sections. 
The idea in making the series of parallel sections, each 
of rather less than half inch in thickness, was not only 
that the changes in the structure could be examined, but
