The experiments were repeated in 1844, the same beds having 

 respectively the same kind of substance applied as in 1843, with 

 the exception of No. 4, which in addition to tiie 18 lbs. of Sul- 

 phate of Magnesia, had also 18 lbs. of Muriate of Lime. Owing, 

 however, to the remarkably dry season, and drier condition of 

 the stems when cut, the weights obtained in 1844 cannot be 

 fairly compared with those in 1843; but respectively with each 

 other in the same year, they may be
