patriotic predilc&ion, seems to forget here, that one of his own country;- 
men had, like Linn/eus, magnified the number of diseases which de- 
solate mankind. 
In the opinion of Dr. William Cullen, that great professor of 
pathology and the Materia Medica , who died at Edinburgh February 
5, 1790, the Genera Morborum of Linnveus was the second systematic 
nosology after that of De Sauvages. And the latter in a subsequent 
edition of his work, adopted himself all the descriptions and the new 
species of Lin naius. All his celebrated successors in pathology, a 
Vogel, a Selle, a Haartman, a Daniel, acknowledged with 
gratitude and impartiality the merits which Linn.eus had acquired by 
his first efforts and knowledge in that science. 
Linn.eus fraught afterwards his system of nosology upon a more 
detailed plan. He also gave le&ures upon the various species of diseases 
(Species Morborum*). This plan however remained a manuscript, 
from which he diftated to his students. The chief result of his medical 
observations and leftures he published in 1766, under the title of 
Clavis Medicines Duplex , Exterior et Interior , Holm, twenty-nine pages 
in odtavo. This work, small as it was, became a compendium of the 
whole science, and an epitomical sketch of the virtues and effects of 
medicines. “ It was like an Ilias in Nuce ,” says Dean B.eck, “ but a nut 
somewhat hard to be cracked to get at the kernel." Linnaeus himself 
confessed that he bestowed much labour upon this little produ&ion, 
and that medicine would still require a man’s whole life, before its
