* At this place a singular pheenomenon was observed by Mr. Rogers. During 

 the extreme cold the branches of a lime-tree, which overhangs a part of his garden, 

 drooped so as completely to lie on the ground, and those above fell proportionately ; 

 there was neither ice nor rime on them to increase their weight, so that this pheno- 

 menon must have been some direct effect of cold. The branches recovered them- 

 selves as the day advanced and grew warmer, and eventually they so completely re- 

 gained their original position, that Mr. Rogers at first thought his gardener had 

 cut away all that drooped, and impeded the path the morning before.
