fume those of the orange, the solitary exception having the 

 attributes of a lemon. Those who are curious in such 

 matters should consult our vol. for 1841 and 1842. The 

 subject is also discussed briefly in Darwin's * Domesticated 

 Animals and Plants.' Various explanations have been 

 offered, but, so far as we know, the only one based on actual 

 experiment is that of Gallesio, who tells us that he impreg- 

 nated an orange with the pollen of a lemon, and that the 

 fruit borne on the mother tree (orange) had a raised stripe of 

 peel upon it, like tHat of a lemon, both in colour and in 

 taste. Supposing this statement to be accurate, we have 

 thus an instance of the influence of the pollen, not on the 

 germ only, but on the germ-case, or ovary, which is of course 

 part of the mother plant."* (Vide pi. 259, for what Risso 

 calls " Bigaradier Bicolor," and " Bigaradier Bizarrerie.")

" Enormous but almost tasteless oranges were served with 

 the dessert I am told that the trees which yield them, and 

 which were planted by the convicts, have deteriorated from 

 want of proper care."

From the " Penny Cyclopaedia " Citrus. 



" In China there is an enormous variety of Citrus, with its 

 lobes all separating into fingers of different shapes and sizes, 

 whence its name of fingered citron. The Chinese esteem it 

 very much, both for its rarity and for the grateful odour of 

 its rind. They place the monstrous fruits on porcelain 

 dishes, and have them in their apartments to fill the air with 

 fragrance." (Called Fo-show-kan, or Buddha's hand.) 



* It is doubtful whether the different varieties of Citrus are so easily 

 mixed up as Gallesio's experiment would imply.
