The number of words in every-day use derived from proper names 
is very great; and from the way they have been altered through igno- 
rance, carelessness, or the “genius” of the language, it is often 
puzzling to trace them to their origin. On what principle did 
the Italian name of the Sun-flower, Girasole, become converted into

edition is required, to obtain for his sheets. the fevision of a botanist, as 
the classification and the information given are often very antiquated.
