NOTE ON AN ORANGE.

between'the former and the latter was only by thready fibres, as shown in 
plate 120 of " Oranges and Lemons of India." It is of the Suntdru 
race, but in this kind the pulp ball could be made to rattle within the 
Orange. 
If we are to believe that the peel represents the under (outer) side of 
the pulp carpel leaves, we have also to believe that the under side of a 
leaf can be separated from the upper side by nearly a quarter of an inch,-* 
as in the ' Laroo.' 
Then there is another difficulty. If the peel is the outer surface of 
the pulp, why does it never insert itself between the pulp carpels '? 
My experience of Oranges leads me to think the latter theory is 
untenable, and I look upon the peel much as I do upon the envelope of 
the Cape Gooseberry (Physalis), only in some kinds the peel is adherent 
to the pulp ball, while in others it becomes quite detached from it.
