This analysis is calculated without carbonic acid or organic matter. 
Soda, in this potato, greatly exceeds the potash, and the amount, of phosphates is greater 
than is usually obtained. Probably the early potatoes are forced forward by the aid of 
rich manures, and hence the excess of phosphates and soda. This, however, is only a 
conjecture, which I have net the means of verifying.
