"Thoughts on a Pebble, or, A First Lesson in Geology"

“The following pages contain the result of my labours. They have been composed under circumstances particularly unfavourable to literary pursuits; and such as those only can duly appreciate, who are aware of the numerous and anxious duties, which a country practitioner is called upon to perform.”

“The Fossils of the South Downs; or Illustrations of the Geology of Sussex”

“Although we may not be able to mark the precise boundary beyond which organic beings do not appear, it is certain that in all geological epochs, subsequent, at least, to that of the primary rocks, animals and plants have existed in successive families; they have been created, have lived their day, and by the operation of physical causes, have perished; while new races have been called into being, and in their turn have ceased to be, in order to give room to other families, requiring, perhaps, a different climate, and a new order of things.”

“In the prosecution of these researches... extraneous fossils were no longer regarded merely as subjects of natural history, but as memorials of revolutions which have swept over the face of the earth, in ages antecedent to all human record and tradition.”

“Whether we speak of the cedar, the oak, the lichens, or the grasses, all equally derive their support from the elements afforded by the mineral world, which, in its widest sense, includes not only the solid earth, but its waters, and all its fiuids—its atmosphere, and all its gases.”

“In the latter part of the seventeenth century, there were several eminent men in England who were greatly in advance of the age in which they lived, and strenuously exerted themselves to discover and promulgate the true principles of Geology. Among these Dr. Martin Lister, physician to Queen Anne, was one of the most distinguished. This accomplished naturalist in his great work on shells... figures and describes many fossil shells as real animal productions, and carefully compares them with recent species. He also recognised the distinction of strata by the organic remains they contain; and to him the honour is due of having first suggested the construction of geological maps...”
