point of development is the Plum tomato, Fig. 8. It approaches 
more nearly a spherical form, and is almost uniformly two-celled. 
Still lower is the Cherry tomato, Fig. 9,—the smallest and sim- 
plest of them all, and two-celled. This is our nearest approach 
to the wild type. The first tomato known to man could have 
this gives us reason to suppose that they may have existed in 
wild nature also. Granting this, they nevertheless give evidence 
of development from the Cherry tomato, as we have seen from 
Fig. 11. This figure shows the complete cell-division whic
