to Natural History, collected during a period of about seven hundred years, from the time of Thales the Milesian, it has a just claim to the attention of every speculative enquirer. It is not surprising, that the progress of the human mind, which, in moral science, after the first dawn of enquiry, was rapid both amongst the Greeks and Romans, should be slow in the improvement of such branches of knowledge as depended entirely on observation and facts, which were peculiarly difficult of attainment. Natural knowledge can only be brought to perfection by the prosecution of enquiries in different climates, and by a communication of discoveries amongst those by whom it is cultivated. But neither could enquiries be prosecuted, nor discoveries communicated, with success, while the greater part of the world was involved in barbarism, while navigation was slow and limited, and the art of printing unknown. The consideration of these circumstances will afford sufficient apology for the imperfect state in which natural science existed amongst the ancients. But we proceed to give an abstract of their extent, as they appear in the compilation of Pliny.
This work is divided into thirty-seven books; the first of which contains the Preface, addressed to the emperor Vespasian, probably the father, to whom the author pays high compliments. The second book treats of the world, the elements, and the stars.

Their notions, however, as might be expected, on a subject so incomprehensible, are vague, confused, and imperfect. In a subsequent chapter of the same book, where the nature of the Deity is more particularly considered, the author’s conceptions of infinite
