It will be observed that the tomato vine differs in composition from that of the potato. 

 The leaf of the tomato contains more silica, and no chloride of potassium. 



This plant evidently requires a rich soil — a rich sandy loam. The varieties of it 

 which may be produced by cultivation, are equally numerous with its congener the potato.
