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...
British scientist and obstetrician (1790–1852)
Gideon Algernon Mantell (3 February 1790 – 10 November 1852) was an English medical doctor, general practitioner, surgeon, and obstetrician, in addition to being an author, and a pioneer geologist and palaeontologist in his "leisure" time. His paleontological collection, a life's labor housed in his private residence at Lewes, and again later at Brighton, also served as a public museum, prior to the sale of the entire collection to the British Museum in 1838. He was an elected member of the Royal Society, the Council of the Geological Society of London, and the Philomathic Society of Paris.

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.

Every part of the earth's surface presents unequivocal proofs that the elevation of the bed of the ocean in some places, and the subsidence of the dry land in others, have been, and are still, going on; and that, in truth, the continual changes in the relative position of the land and water, are the effects of laws which the Divine Author of the Universe has impressed on matter, and thus rendered it capable of perpetual renovation:—
Art, Empire, Earth itself, to change are doomed;
Earthquakes have raised to heaven the humble vail,
And gulf's the mountain's mighty mass entombed,
And where the Atlantic rolls wide continents have bloomed.
It is surely unnecessary to dwell on the interest and importance of a study which instructs us that every pebble we tread upon bears the impress of the Almighty's hand, and affords evidence of Creative wisdom; that every grain of sand, every particle of dust scattered by the wind, may be composed of the aggregated skeletons of beings, so minute as to elude our unassisted vision, but which possessed an organization as marvellous as our own;—a science discoveries have realized the wildest imaginings of the poet,—whose realities far surpass in grandeur and sublimity the most imposing fictions of romance;—a science whose empire is the earth, the ocean, the atmosphere, the heavens;—whose speculations embrace all elements, all space, all time;—objects the most minute, objects the most colossal;—carrying its researches into the smallest atom which the microscope can render accessible to our visual organs,—and comprehending all the phenomena in the boundless Universe, which the powers of the telescope can reveal.
If I have succeeded in explaining in a satisfactory manner, how by laborious and patient investigation, and the successful application of other branches of natural philosophy, the wonders of geology have been revealed—if I have removed but from one intelligent mind, any prejudice against scientific inquiries, which may have been excited by those who have neither the relish nor the capacity for philosophical pursuits—if I have been so fortunate as to kindle in the hearts of others, that intense and enduring love and admiration of natural knowledge, which I feel in my own,—or have illuminated the mental vision with that intellectual light, which once kindled can never be extinguished, and which reveals to the soul the beauty, and wisdom, and harmony of the works of the Eternal, I shall indeed rejoice, for then my exertions will not have been in vain. And although my humble name may be soon forgotten, and all record of my labours be effaced, yet the influence of that knowledge, however feeble it may be, which has emanated from my researches, will remain for ever; and, by conducting to new and inexhaustible fields of inquiry, prove a never-failing source of the most pure and elevated gratification.
In circumstances where the uninstructed and incurious eye can perceive neither novelty nor beauty, he who is imbued with a taste for natural science will everywhere discover an inexhaustible mine of pleasure and instruction, and new and stupendous proofs of the power and goodness of the Eternal! For every rock in the desert, every boulder on the plain, every pebble by the brook-side, every grain of sand on the sea-shore, is fraught with lessons of wisdom to the mind which is fitted to receive and comprehend their sublime import.
"From millions take thy choice,
In all that lives a guide to God is given;
Ever thou hear'st some guardian angel's voice,
When nature speaks of heaven!"
Every walk we take offers subjects for profound meditation,—every pebble that attracts our notice, matter for serious reflection; and contemplating the incessant dissolution and renovation which are taking place around us in the organic and inorganic kingdoms of nature, we are struck by the force and beauty of the exclamation of the poet—
"My heart is awed within me, when I think
Of the great miracle which still goes on
In silence round me—the perpetual work
Of Thy Creation, finished, yet renewed
For ever!"
Every artificial excavation—every well and cellar—every cut for a fort, common road, railway, or canal—every quarry—every tunnel through a mountain—and every pit and gallery of a mine bored into the solid earth, furnish means of investigating its interior. Still more do the inland precipices, and the rocky promontories and headlands along the rivers, lakes, seas, and oceans; the naked mountain-sides ribbed with strata, that bound the defiles, gorges, and valleys; the ruins accumulated at the feet of lofty pinnacles and barriers, and those that have been transported and scattered, far and wide, over the earth; present us with striking features of the internal structure of our planet. Most of all, do the inclined strata push up their hard edges, in varied succession, and thus faithfully disclose the form and substance of the deep interior, as it exists many miles and leagues beneath the observer's feet.
Geology... possesses the great advantage of presenting subjects adapted to every capacity; on some of its investigations the highest intellectual powers and the most profound acquirements in exact science are required; while many of its problems may be solved by any one who has eyes and will use them; and innumerable facts illustrative of the ancient condition of our planet, and of its inhabitants, may be gathered by any diligent and intelligent observer.
It appears that in the lapse of ages, the sea alternately encroaches on and retreats from the land, and the districts it formerly occupied become the habitation of terrestrial animals and vegetables;—but other revolutions succeed, the sea returns to its ancient bed, and the countries from which it retires, are again fitted for the reception of their former inhabitants.
