APPENDIX. 
I. Either they were lodged in the most recent marine 
sediments of the tertiary formation, like the elephant in the 
crag of Norfolk, the rhinoceros of Piacenza, and the mas¬ 
todon of Dax and Asti; 
II. Or in antediluvian fresli-water deposits, analagous 
to those which contain the rhinoceros, elephant, hippopo¬ 
tamus, and mastodon in the VaF d’Arno; 
III. Or in diluvial accumulations more recent than 
either of these formations, and spread irregularly, like a 
mantle, over them both. 
Now, as we find on careful examination of the matrix 
adhering to these bones, that it contains neither fresh-water 
nor marine shells, and is wholly different in character from 
all the specimens which contain such shells, and which 
thereby enable us to refer them respectively to fresh-water 
or marine origin; the most probable conclusion we can 
arrive at is, that the bones belong to neither of these form¬ 
ations, and that their matrix is of the same diluvial cha¬ 
racter with that in which the greater part of the fossil 
bones of Mammalia have been discovered in Europe. 
Having proceeded thus far in our consideration of the 
nature of the bones before us, the time when the animals 
lived to which they belong, and the most probable causes 
that brought them to their actual place and condition,— 
we may now consider the evidence on which it has been 
asserted in the preceding pages, that the strata subjacent 
to the Burmese diluvium, along nearly three hundred 
miles of the course of the Irawadi, from Prome to Ava, 
present a repetition of the geological structure of Europe. 
From the examination of the specimens, compared with 
the notes in Mr. Crawfurd’s journal, the following form¬ 
ations may be recognised with a greater or less degree of 
certainty.
