The carbohydrates are chiefly starch and sugar. 



We are unable to give any further particulars about these 

 tubercles, which are derived from a special variety and 

 consumed in India. 



Seeds received from Calcutta and sown at Reduit g-ave 

 plants of fine growth. We have noticed swellings which, 

 in the variety with ivory white flowers, were of similar form 

 to those of the variety with blue flowers. 



The mineral composition of the roots resembles that of 

 the seed, with the difference that the proportion of magnesia 

 is higher in the root, whilst the phosphoric acid content is 

 greater in the seed. 



The cortical parenchyma is richer in nitrogen, and the 

 proportions of magnesia and phosphoric acid are smaller.
