ANALYSES OF THE SWEET POTATO. 



2. Analysis of tfie tubers. 



98-911 



It will be seen, by comparing the amount of potash in the Sweet potato with that in the 

 common potato, that a very close resemblance exists between them in the amount of 

 potash. There is also the same close resemblance in the percentage of the ash ; but it is 

 proper to remark that the percentage of ash may be rather low, on account of its easy 

 fusibility and its liability to causticity.
