Plate XII. 



Seeds from Bulfum pears. The two lower rows are self-pollinated. Nos. 549, 550, 

 and 551 are from flowers pollinated with Bartlett. Those without numbers are from 

 pears taken from the tree at large for comparison. They are very plainly to he 

 classed among the crosses, thus corroborating the evidence of the external appear- 

 ance of the fruits as shown on Pis. vii and viii. The descriptions of these seeds 

 will be found on pp. 65-67.
