Pliny the elder, nearly four hundred years later, compiled an extensive 

 work on natural history, but without offerinp; a system, or adding any 

 original matter of scientific value, although the large collections of living 

 animals in Rome must have afibrded him many facilities for study. 



Galen paid more attention to the internal stiiicture than to the formation 

 of a system; and from his time, A.D. 200, to the fifteenth century nothing 

 was done of any account. 



Belon, the reviver of natural history in modern times, was born in 1517, 

 and after travelling three years in Europe, Egypt, Greece, and Asia Minor, 

 at the expense of the bishop of Mans and Clermont, and the cardinals of 

 Tournon and Lorraine, he returned to Paris in 1550 with a large collection, 

 when he published his works. 



RoNDELETius, a uicdical professor at Montpellier, published a work in 

 1554, on Ichthyology ; and another appeared in the same year, upon the 

 same subject, by Salviani, a Roman physician. 



Conrad Gesner, a physician born at Zurich, in 1516, published an 

 extensive history of animals in 1585. 



Aldrovandi, a professor of Bologna, born in 1525, was the author of 

 fourteen folio volumes, published between 1599 and 1640. 



Mouffet's Theatnim insectorum^ the earliest English zooL^gical work, 

 was published in 1634. Most of the authors of this period repeated the 

 fables of Pliny, or were deceived by those who sold factitious curiosities, a 

 remnant of which still remains in the occasional appearance of a stuffed 

 mermaid or impossible fossil. It was not until the appearance of Linnseus 

 that natural science was placed upon a permanent basis. Born in Sweden, 

 in 1707, he was at first intended for the Church, but subsequently studied
