I860.] BRYOLOGY OF OXFORD. 369 



I was greatly struck with observing in the border of a field 

 near to the old Abbey an enormous Pear-tree. It is about four 

 feet from the ground, fifteen feet iu circumference^ and must 

 have stood the storms and tempests of many centuries ; it was 

 partly decayed, but still capable of bearing fruit. Have any of 

 our botanical friends seen a larger Pear-tree than this ?
