THE ORANGE GENUS. 339 



his ' Traill- du Citrus' at Paris, in 1811. He 

 maintains tiiat the orange, instead of beinj^ found in 

 the north of Africa, in Syria, or even in Media, 

 whence the Romans must liave obtained their " Me- 

 dian Apples," was not in that part of India which is 

 watered by the Indus at the time of Alexander the 

 Great's Indian expedition, as it is not mentioned by 

 Nearchus amonj^ the fruits and productions of that 

 country. It is not mentioned either by Arrian, by 

 Diodorus, or Pliny ; and even so late as the year

The first distinct mention of oranges is by the 

 Arabs ; and Avicenna (book v.) not only describes 

 oleum de cilrangula (oil of oranges) and oleum de 

 cilrangulorum seminibus (oil of orange seeds), but 

 speaks of citric acid (salt of lemons), which is con-

 that species from which it got its common English 

 name. 



According to Galessio, the Arabs, when they pene-

 they brought them thence by two routes : the sweet 

 ones, now called China oranges, through Persia to 

 Syria, and thence to the shores of Italy and the 

 south of France ; and the bitter oranges, called in 

 the commerce of England, Seville oranges, by Arabia, 

 Egypt, and the north of Africa to Spain. 



It does not appear that the orange was originally 

 a Chinese fruit, as it is not mentioned by Marco 

 Polo, the father of modern travellers, who is so cir- 

 cumstantial in describing all the other wonders of 

 that country. 



Now these facts certainly go far to shew that the 

 orange was not known to the ancients either in Eu-
