It may safely be taken for granted here, that if the hme 

 had acted as a nutritive element in the developement of 

 the meadow plants, the plot manm^ed with carbonate of 

 lime ought to have given a higher, but assuredly in no 

 case an inferior crop, than the unmanured plot. But the 

 very reverse is the case : the carbonate of hme, which 

 could only spread through the soil dissolved in carbonic 

 acid, had an unfavourable effect ; the caustic hme, on the 

 contrary, was beneficial. 



Among the Saxon experiments akeady so often alluded 

 to, there are two of sufficient importance to deserve par- 

 ticular mention here. One of these was made by 

 Traeger, of Oberbobritzsch ; the other by Triiger, of 

 Friedersdorf The latter omitted to make a comparative 

 experiment to show the difference between the produce 

 from a plot manured with hme, and that from an unma- 

 niu-ed plot of the same size. Instead of the latter, there- 

 fore, I placed here by the side of the hme experiment, for 

 the sake of comparison, another made with ground bones 

 on a plot of the same size.
