also. { As soon as one found himself unequal to the 

 progress of the other in one species of study he dedi- 

 cated himself to another. They therefore divided the 

 kingdoms and provinces of nature between them.' l They 

 began to study insects and fishes together, but in a 

 short time Linnaeus yielded the palm to Artedi in ich- 

 thyology and the latter acknowledged Linnaeus to be his 

 superior in entomology. Artedi undertook to reduce 

 amphibia, and Linnaeus birds, under a regular arrange- 

 ment. Each kept his discoveries to himself, 2 though 

 for no length of time, since not a day passed without 

 one surprising the other by narrating some new fact. 



Artedi finally confined his botanical studies to the 

 umbelliferous plants, in which he pointed out the dis- 

 tinction which arises from the differences of the involu- 

 crum, leading to a new method of classification, which 

 was afterwards published by Linnaeus, with a tribute to 

 his friend. i But the chief object of Artedi's pursuits, 

 which transmitted his fame to posterity,' says the rap- 

 turous old Stoever, ' was the empire of Neptune, or the 

 knowledge of the natural history of fishes, called ichthy- 

 ology. Linnaeus relinquished to him this province.' 

 Emulation is the soul of improvement. Laying their 

 plans so as to assist each other in every branch of natural 

 history and medicine, Artedi had projected the happy 

 plan of introducing a new method and classification in 

 ichthyology, which cheered' and strengthened Linnaeus 

 to effect the same thing in botany. They ' worked
