Pas;e i^z 
in favor of the Atlantis theor}-, providing it be admitted that 
the Atlantis was pre-miocene. 
In the last volume (the 22nd) of the Quarterly Journal 
of the Geological Societ}'. I have given the arguments 
upon which I base my views as to the Atlantis hj^pothesis ; 
and as no one has yet shown those views to be untenable, 
I shall now only briefly state that m3" conclusions, derived 
from a careful stud}’ of all the evidence, are that the Atlan- 
tis continent was most like!}’ pre-miocene, and that during 
the miocene period probabh’ onh’ the higher summits of 
the land remained as coral islands, much as in the existing 
Pacific Ocean. This view is .strongl}’ supported b}’ the 
evidence before referred to, which has been brought forward 
b}' Forbes and God win- Austen, and which has been con- 
curred in b}’ Darwin, and further .supported b\’ Dr. Duncan’s 
inve.stigations. 
The migration then of organized beings during the mio- 
cene period, as indicated b}’ the alliances of the fo.ssil and 
recent animal and jilants, was probabh’ from meridional 
America acro.ss the Atlantic and through North Africa and 
South Eurojie to the East Indies. 
S3. The C/assiftcntioft of the Tertiary Rocks of Trinidad. 
The researches which have been made into the paleonto- 
log}' of the tertiar}' strata of Trinidad enable me to offer an 
improved classification of these rocks. At the .same time I 
mu.st state that 1113- opportunities have not .sufficed for a 
satisfactor}^ determination of all the beds included b}’ Me.ssrs. 
Wall and Sawkins in the Tamana Series nor of those com- 
posing the Na]mrima Marls. Neither have I been able to 
inve.stigate the relation.ships of either the Moruga or the
