LINN.EUS, 1758, 1766. 

 'Systema Naturae,' Editio decima, editio duodecima. 



The progress of science during Linne's lifetime (1707-1778) is indicated 

 by the fact that twelve editions of the 'Systema' appeared between 1735 

 and 1766, the book growing in the meantime from a mere brochure of twelve 

 pages to a work of 2400 pages. (Allen, 1908, p. 13.) The whole animal 

 kingdom as then known is listed in an orderly, systematic manner, with 

 much philosophical analysis, clear, workable diagnoses, and a vast amount 

 of usually correct detail. 



Among Linne's lasting contributions to science we may notice first his 

 reform of botanical and zoological nomenclature. This included: (1) the 

 definition of species by short descriptive phrases; (2) the adoption of single 

 conventional names (often the Latin equivalent of the popular or trivial 

 names), which were at first placed in the margins alongside the specific 

 phrases. These were introduced very tentatively at first but in the 'Species 

 Plantarum,' 1753, and 'Museum Adolphi Friderici,' 1754, finally supplanted 

 the more cumbersome descriptive phrases or difl^erentia. Thus arose the 

 modern binomial system of nomenclature. 



Certain authors previous to Linnseus, notably Jacob Testut in 1635 (Un- 

 derwood, 1907, p. 501) and John Ray, had used names that were binomial 

 in form {e. g., Ovis strepsiceros Ray, see above, p. 17) but the system never 

 came into general use until after its development by Linnaeus. 



A second and most enduring claim of Linnaeus upon the grateful mem- 

 ory of posterity arises from his recognition of the fundamental importance
