PLATE XL. 



Four figures of Citrus aurantium, taken from Eisso and Poiteau's monograph. 



a is called " Granger a fruit conif&re," with pale yellow pulp; half sweet and half acid, with a 

 little bitterness. The authors say this variety is on the debatable ground between 

 the oranges and lemong. 



6 is the " Granger a fruit pyriform." The pulp is orange-yellow in the centre, and blood- 

 coloured towards the rind. It is very fine flavoured. 



c is the " oranger a fruit toruleux," with the rind-carpels distinct. 



d is the "oranger a fruit rugneux," commonly called "oranger des bois de St. Domingue." 



Kisso states that in St. Domingo this orange was used by preference in cases 

 of weakness after fever. 



It is not impossible that the Italians may have got the notion of " decoction 

 of lemon" for fever, and weakness after fever, from the West India Islands.
