ago) as one of those inexplicable j)lienomena occurring among plants. If I 

 mistake not, Mi-. M'Nab added that the tender tops might be struck as 

 cuttings, while the stems were shattered into shreds by the frost. 



It is well known that those plants which have the thinnest or most watery- 

 sap are more liable to be killed by frost than those which have gummy or 

 resinous juices j those which have a flexible or yielding texture, are less 

 liable to be ruptured than such as are rigid in habit; clover is decomposed, 

 while wheat is only withered, without any laceration of the leaves. 



So, in the case of heaths, the tops are flexible, and yield without fracture 

 to the congelation within ; whereas the stems, though almost sapless, are so 

 rigid in their vascular structure, that they are rent to pieces. A cast-iron 

 tube of 6 in, diameter, and 2 in. bore, filled with water, and exposed to keen 

 frost, will bui'st as easily as a tube of paper; whereas a bladder filled and 

 exposed in like manner will escape scathless, in consequence of the expansi- 

 bility of the integument. 



I may be mistaken in this my supposition ; but it was the only reasoning 

 which occurred to me, in accounting for the destruction alluded to, — /. Main.
