The vitamin B complex is generally accepted as containing at least five distinct components for the rat; B1 (thiamin), flavin, nicotinic acid, B6, and the filtrate factor. Work by Jukes and Babcock (1) and by Oleson and co-workers (2) indicates that a distinct antiparalytic factor (very likely Reader's "B4") exists. Stocks tad (3) has reported a growth factor "U" for the chick. One of the authors (4) has given evidence of the existence of still another factor, the "8B factor," in the B complex. That chondroitin sulfuric acid is a growth factor for the rat has been suggested by Robinson and co-workers (5). This paper deals with further study of the SB factor and its relation to the other factors.
