Upon the whole this extremely difficult subject is treated through- 

 out with considerable skill and great learning. Absolute data are 

 however wanting for ascertaining the origin of many, and especially 

 of locally cultivated species ; and we fear that we should have reduced 

 the first class and enlarged the second. 



This subject naturally leads to another still more embarrassing, 

 the original countries of the cultivated species. By far the greater ma- 

 jority are assigned to the Old World: 35 to Europe, 33 to Northern 

 and Western Asia, 1 (Date) to North Africa, 3 (one kind of Indigo, 

 Coffee, and one kind of Cotton) to Tropical Africa, 40 to Southern 

 Asia and the Malay Archipelago; none to South Africa or Australia 

 or New Zealand, and a few are doubtful; 33 are assigned to America. 

 Oue only {Cucurbita Melopepo, L.) is wholly unknown, and considered 

 as probably a cultivated race of some existing wild species. 



The most striking result, as it appears to M. de Candolle, to be 

 derived from the above inquiry, is the great antiquity of the majority 

 of the cultivated varieties or races. In the sixteenth century the 

 principal kinds of Cabbage, Turnip, and Gourds were known; besides 

 cereals and fruit-trees, whose identity with those now cultivated is less
