152 PROCEEDINGS OP THE SCIENTIFIC ASSOCIATTONV 
in favor of the Atlantis theory, providing it be admitted that 
the Atlantis was pre-miocene. 
In the last volume (the 22nd) of the Quarterly Journal 
of the Geological Society, I have given the arguments 
upon which I base my views as to the Atlantis hypothesis - r 
and as no one has yet shown those views to be untenable, 
I shall now only briefly state that my conclusions, derived 
from a careful study of all the evidence, are that the Atlan- 
tis continent was most likely pre-miocene, and that during 
the miocene period probably only the higher summits of 
the land remained as coral islands, much as in the existing 
Pacific Ocean. This view is strongly supported by the 
evidence before referred to, which has been brought forward 
by Forbes and God win- Austen, and which has been con- 
curred in by Darwin, and further supported by Dr. Duncan’s 
investigations. 
The migration then of organised beings during the mio- 
cene period, as indicated by the alliances of the fossil and 
recent animals and plants, was probably from meridional 
America across the Atlantic and through North Africa and 
South Europe to the East Indies. 
§3. The Classification of the Tertiary Roch of Trinidad.' 
The researches which have been made into the paleonto- 
logy of the tertiary strata of Trinidad enable me to oiler an 
improved classification of these rocks. At the same time I 
must state that my opportunities have not sufficed for a 
satisfactory determination of all the beds included by Messrs. 
"Wall and Sawkins in the Tamana Series nor of those com- 
posing the Naparima Marls. Neither have I been able to 
investigate the relationships of either the Moruga oi the
