In 1822, Mr. Parkinson published "An Introduction to the Study of Fossil Organic Remains, especially of those found in the British Strata; intended to aid the Student in his Inquiries respecting the Nature of Fossils, and their Connexion with the Formation of the Earth;" 1 vol. 8vo. with ten plates, principally of the genera of fossil shells. He also contributed a few papers to the early volumes of the Geological Society of London, of which he was one of the original members. After Mr. Parkinson's death, his beautiful and choice collection was sold by auction, and its contents widely dispersed. The fine series of silicified zoophytes was purchased by Mr. Featherstonhaugh, and taken to America; and some years afterwards was destroyed by a fire which consumed the museum in which it was placed. As illustrative of the pleasing style of Mr. Parkinson's work, I subjoin an abstract of the chapter, _On the Pleasure and Advantages of a Knowledge of Fossil Remains_. The epistolary style was adopted; and the first letter is supposed to be penned by a friend desirous of learning the nature of certain fossils he had observed on his journey to Oxford:-- "I have lived long enough to witness many sad disappointments to the fond dreams of happiness indulged by persons who, only intent on the acquisition of riches, had neglected to cultivate any intellectual or ennobling pursuit; so that on retiring from active life, they were unable to enjoy the leisure so dearly earned by years of anxiety and care, and either relapsed into a state of miserable ennui, or gave themselves up to the excitement of frivolous or vicious indulgences. "Aware of the necessity of devoting the few leisure hours, which the duties of my calling left at my disposal, to some rational and amusing occupation, I have always cultivated, more or less assiduously, some branch of art or science, and thence acquired an enthusiastic admiration for the beauties of nature, and an insatiable curiosity to pry into the mysteries of the natural world. With this state of mind, I have at length resolved to avail myself of the means my little fortune affords me to indulge those feelings, and have, I trust, quitted the busy scenes of the world for ever. "In pursuance of a plan long entertained of visiting the most interesting parts of our island, I left London last week, accompanied by my daughter, and our old friend, Frank Wilton, whose lively disposition and agreeable manners render him, as you well know, an excellent companion. But he has made himself most acceptable to us on another account;--his resolute scepticism with respect to the more rational, and his submissive credulity as to the popular and traditional explanations of such natural phenomena as are beyond his comprehension, are frequently productive of remarks so quaint and humorous, as to contribute in no small degree to our enjoyment.
