PERHAPS it is useful to direct attention to the above subject before confusion gets worse confounded. It was pointed out in 1931 that the use of the terms vitamin B2 and anti-dermatitis (anti-pellagra?) factor interchangeably was already causing difficulties1. The discovery by Kuhn and his co-workers that lactofiavine is able to supplement a vitamin B2-

A CHEMICAL study of vitamin B2 in a cold aqueous extract of commercial liver extract (Eli Lilly, No. 343) has been made. This solution is very rich in vitamin B2, being effective in producing good growth in young rats on a B2 deficient diet, in a daily dose representing 40–60 mgm. of the original liver extract.
