. There he held office until 1842, when ill health led him to resign.

The ability with which he edited the publications of the society and advised the council on every obscure and difficult point was commented on by Murchison in his presidential address (1843). In 1829 Lonsdale read before the society an important paper On the Oolitic District of Bath (Trans. Geol. Soc. ser. 2, vol. iii.), the results of a survey begun in 1827; later he was engaged in a survey of the Oolitic strata of Gloucestershire (1832), at the instigation of the Geological Society, and he laid down on the one-inch ordnance maps the boundaries of the various geological formations.

He gave particular attention to the study of coral
Coral
Corals are marine animals in class Anthozoa of phylum Cnidaria typically living in compact colonies of many identical individual "polyps". The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.A coral "head" is a colony of...

Lonsdale's paper, Notes on the Age of the Limestones of South Devonshire (read 1840), was published in the same volume of the Transactions of the Geological Society (ser. 2, vol. v.) with Sedgwick and Murchison's famous paper On the Physical Structure of Devonshire, and these authors observe that the conclusion arrived at by Mr Lonsdale, we now apply without reserve both to the five groups of our North Devon section, and to the fossiliferous slates of Cornwall
Cornwall
Cornwall is a unitary authority and ceremonial county of England, within the United Kingdom. It is bordered to the north and west by the Celtic Sea, to the south by the English Channel, and to the east by the county of Devon, over the River Tamar.
