 " Obfervations on the Difeafes, Defects, 8Cc." 



Since I publifhed my " Obfervations on the Difeafes, De-

 great many hollow trees that had, when I took them in hand, 

 little more than the bark remaining found, have within thefefew

 within a few feet of the ground, have their flumps now com-

 and the places where they were headed are only difcerned by 

 a faint cicatrix. Of a great many, I mall only particularize 

 a few infhances. 



A Lime-tree, about eighteen inches in diameter, whofe 

 trunk was decayed and hollow from top to bottom, to which, 

 after cutting out the decayed wood, I had applied the Com- 

 pofition about fixteen years ago, was cut down lad year on

 part, and was found entirely filled up with new found wood,
