Mr. Conybeare was one of the earliest promoters of the Oeological Society, and the important services ha has rendered to geological science may be seen in his numerous papers printed in the Society's ' Transactions.' He is the discoverer of the Plesiosaurus, that strangest of all the antediluvian monsters, and for his descriptions of the animal Cuvier paid him the highest compliment that can be offered by one scientific philosopher to another. His papers on the coal-fields, giving a description of the physical geography of important districts, estab lishing the relations of some of the most remarkable British rocks, and their order of superposition, have ever siuce furnished data for practical purposes, and shown bow the absurd mistakes of mining speculators were to be avoided. As will be seen from the subjoined titles, his researches have extended to various branches of inquiry. his first paper presented to the Geological Society is On the Origin of a remarkable class of Organic Impressions occurring in Nodules of Flint,' vol. ii., 1814 ; 'Descriptive Notes referring to the Outline of Sections presented by a part of the Coasts of Autrim and Derry,' voL iii., 1816, made in a tour conjointly with the Rev.
