CANKER. This disease is accompanied 

 by different symptoms, according to the 

 species of the tree which it infects. In 

 some of those whose true sap contains a 

 considerable quantity of free acid, as in 

 the genus Pyrus, it is rarely accompanied 

 by any discharge. To this dry form 

 of the disease it would be well to confine 

 the term canker. In other trees, with 

 sap abounding in astringent or gummy 

 constituents, it is usually attended by a 

 discharge. In such instances it might 

 strictly be designated ulcer. This dis- 

 ease has a considerable resemblance to 

 the tendency to ossification, which ap- 

 pears in most aged animals, arising from 

 their marked tendency to secrete the 

 calcareous saline compounds that chiefly 

 constitute their skeletons. The conse- 

 quence is, an enlargement of the joints 

 and ossification of the circulatory vessels 

 and other parts, phenomena very analo- 

 gous to those attending the cankering 

 of trees. As in animals, this tendency 

 is general throughout their system, but, 

 as is observed by Mr. Knight, " like the 

 mortification in the limbs of elderly
