It will be observed that the proportion of water and solid 

 matter is pretty nearly the same in all the roots of the different 

 experimental plots. The differences in the amount of water in 

 roots of different size also are very trifling : generally, but not 

 always, the larger roots were somewhat richer in water. 



In the following table the proportion of ash and nitrogen in 

 swedes in natural and dry state is given :
