adequately dealt with, but many features, for the most part unexpected, 

 have been revealed. 



The polysaccharides, like many other research fields, are, after all, 

 not so complicated as they appeared when viewed from afar, and the 

 close relationship now established between cellulose and starch, starch 

 and lactose, inulin and sucrose, will, it is hoped, play a part in bringing 

 within the range of exact experiment the structural study of all types 

 of natural compounds related to the simple sugars.
