Abstract
ALTHOUGH our knowledge of the constitution and nature of vitamin D is greater than our knowledge of the chemical composition of the other accessory factors, recent work suggests that it will not be long before it has advanced to a comparable stage. Progress has been particularly striking in the case of vitamin B, and has followed two lines: the physiological function of this compound in the animal economy has been investigated by a number of observers, whilst at the same time much information has been obtained as to its chemical nature and properties.
