PROCEEDINGS OF THE SCIENTIFIC ASSOCIATION, 
here have operated to render the report on our island 
far less complete than that of Jamaica. Besides this, since 
the Report on Trinidad has been published, a great deal of 
work has been aecomplishd on the paleontology and natural 
history of the Westindies; aud the relations of the fossil 
shells, echinoderms, corals arid foraminifera of theCaribean 
area have been largely worked out. Sir Roderick Mur- 
chison remarks in his preface to the Jamaica Report that 
the Appendix to that report by Mr. Etheridge, paleontolo- 
gist to the Geological Survey of Great Britain, is not the 
least valuable portion of the book : and indeed I may say 
that to Naturalists it is the most interesting part of it. 
Mr. Etheridge’s appendix relates to the paleontology of the 
island; and in it he has done full justice to the labors of 
Professors Duncan, Rupert Jones, and others, whose results 
have been published, with excellent illustrations for the 
most part, in the Journal of the Geological Society and in 
the Geological Magazine. He has presented such a re- 
sume of our knowledge of the paleontology of the Oavibeau 
area as cannot fail to bo highly useful if not indispensable 
to every worker on the Geology of that area. On one point 
alone have I to sa}' anything in disparagement of this 
report— that is the numerous misprints in ad the appen- 
dices, but particularly in the botanical and paleontological 
portions. In all othor respects the work is well executed : 
there are, besides a general geological map of the island, 
numerous detailed sections showing the structure of the 
island.
