6 On the Varieties of the Citrus. [Appendix. 



varieties, are collected. When Dr. Sickler was at Rome, the most 

 distinguished of those houses was that of Prince Antonio Bor- 

 GHE8E, in which, he relates, there were upwards of 70 sorts of 

 lemons and oranges accumulated ; and among them some, that 

 are not to be seen any where else. The culture of those trees, in 

 that house, was particularly well understood and conducted ; and 

 no other, not even that of the Pope, could vie with it. Such a 

 house it would be worth while for any one to see, who is inter- 

 ested in the treatment and cultivation of those plants. 



As you proceed from Rome towards Naples, and thence far- 

 ther south, the view of those plantations become more and more 

 striking. It is for the traveller to describe their beauty, and the 

 pleasure that is experienced on entering such a grove. 



The quantity of fruit produced, and the consumption of it, 

 throughout Italy, are surprising. Hardly any other fruit is eaten. 

 There is only a suspension, in the use of the Agrumi, during 

 the hottest part of the summer, when their ascidity is supposed 

 to be injurious to the constitution, weakening, and productive of 

 fevers. 



Dr. Sickler divides all the Agrumi into Two Classes, under 

 which there are divisions and subdivisions. This arrangement, 

 as has before been intimated, is not botanical ; the species and 

 varieties are not distinguished, but are promiscuously to be 

 looked for, in their several compartments. Thus, for example, 

 the Shaddock, or Citrus Decumana, will be found in the second 

 class (the oranges), third division (sweet oranges), eighth sub- 

 division (being the eighth sort.)
