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, … - Gideon Mantell

I had every reason to believe that my collection would be permanently established in Sussex, and serve as the foundation for a County Museum. In that expectation I have... been utterly disappointed. ...after the death of my noble and lamented friend, the late Earl of Egremont, the munificent patron of the Institution, the proposed measure was abandoned... I have therefore, in compliance with the wishes of my scientific friends, disposed of my entire collection to the Trustees of the British Museum. ...that collection, which would have been of tenfold importance if located in the district from whence it was derived, and whose physical structure it was designed to illustrate, is now broken up, and will be dispersed through the cabinets of our National Institution... a time will assuredly come, when their endeavours to promote a taste for scientific knowledge among the intelligent inhabitants of Sussex, and to direct attention to the investigation of its physical phenomena, will he properly appreciated, and the failure of their attempt to secure to the county a collection so rich in its peculiar fossil and mineral productions, be remembered with regret.

It seems scarcely credible, that but little more than a century ago it was a matter of serious question with naturalists, whether the petrified shells imbedded in the rocks and strata were indeed shells that had been secreted by molluscous animals; or whether these bodies, together with the teeth, bones, leaves, wood, &c., found in a fossil state, were not formed by what was then termed the plastic power of the earth; in like manner as minerals, metals, and crystals.

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.
