No part of Linn^us's writings had given more 

 offence to the contemporary botanifts, than the 

 liberty he had taken in changing tht generic names 

 of plants, which had neceffarily taken place in 

 many inftances, from the rules eftablifhed by the 

 Fundamenta. Even Dillenius was by no means 

 reconciled to this innovation. Linn^us, who had
