Natural History has of late become a favourite pursuit in this country; and although its progress as a study may not have been equal to the enthusiasm which it has excited its general effect is unique beneficial. In consequence of the interest which it has created a great variety of works, from the simple catechism to the elaborate treatise have appeared in rapid succession. But while compends and manuals are thus multiplied, little has been said with regard to the private history and professional pursuits of the distinguished persons who have contributed most to the general stock of knowledge from which these popular essays have in a great measure been derived. We have, therefore, endeavoured in some degree to supply this deficiency, by presenting a series of Lives of the more Eminent Zoologists, from Aristotle to Linnseus in.
