but we have to wait till it produces seed and the offspring 
comes true. 
Fig. 18 gives a good illustration of the narrow-leaved variety 
of Hevea brasiliensis, which we have reproduced to show not 
only the excellent distinctness and taste with which Javanese 
natives draw natural objects, but also a peculiarity of young 
developing leaves as they are so often met with in tropical 
regions. Whereas the adult leaves are leathery, firm and turg- 
escent, the young ones hang down quite limp and as if withered 
and faded. Besides, they are of a transparent brown colour, 
calling to mind some of our Potamogetons, whereas the adult 
are hard green. Another deviation, found by Mr. Smith on the 
narrow leaved specimen is represented in fig. 19. In this case 
the middle leaflet has grown out normally, but the two lateral 
have been reduced to small triangular appendages.
