In comparison with the last numbers of the actual sulphur in 
the dry clover, we give the proportion of sulphur as found in the 
asli of 1000 parts of the plants calculated from the foregoing 
analysis : —

It will be seen that, in the case of the red clover, fully two- 
thirds of the whole sulphur is dissipated in the combustion, and we 
conclude* that at least this proportion must have existed in the 
plant in some other condition than as sulphuric acid. With the 
purpose of exhibiting the extent of mineral exhaustion due to a 
clover-crop, we have drawn up a table of the amount of the 
various substances in a ton of red and white clover-hay. The 
average of the two analyses is taken in each case, and for the 
sake of uniformity the calculations are upon specimens containing 
12 per cent, of water. 
The carbonic acid of the ash is omitted.
