Rather startling is Barger’s tentative conclusion that vitamin A deficiency is the predisposing factor in convulsive ergotism, a theory suggested by Edward Mellanby’s observations on dogs and the peculiar distribution of this form of ergotism, which almost never occurs in France, a land rich in dairy products, but does occur in districts of Germany where the reverse is the case, ergotizm also in families deprived of milk and butter.
