It is already evident that wider knowledge of the constitution of these 
polysaccharides will lead to great advances in medicine on the side of 
immunology. In order that this branch of the subject may be developed

outline of the broad general results obtained in this field. In concluding 
this review I thank most warmly those of my helpers who by. their 
devotion and skill have contributed to this scientific advance.
