Plate VIII. 



Outlines of Bnffnm pears. Figs. 1-6 are from flowers inclosed in paper bags, 

 therefore self pollinated. Figs. 7-12 are from flowers outside the hags, on the 

 same trees, evidently cross-pollinated by insects. PI. xii contains photographs of 

 the seeds of all the self-pollinated fruits with the same record numbers. On the same 

 plate seeds without record numbers may be found w^hich are from insect-crossed 

 fruits, but there is no means of associating any particular group of seeds with its 

 fruit. The descriptions are on pp. 65-68.
