W.G.B. writes: - Referring to article in January number entitled "Grape juice for all," I think perhaps it would interest others besides myself if Dr Knaggs would give us his opinion on the value of what are commonly termed "Water Grapes," as compared with more expensive kinds.

On the Continent the grape cure is a popular method of treatment. It is especially good for those who are anaemic and underfed as well as for those who suffer in the opposite way from over-feeding. It depends upon which condition is present as to the kind of grapes selected for the cure.

Fully ripe grapes with but little acidity (water grapes) are best suited for persons suffering from anaemia and malnutrition. The unripe or sour grapes answer best for cases of over-eating associated with constipation, gout and allied disorders of nutrition. The excess of acid and cellulose helps the bowels and promotes elimination of the gouty poisons.

Our correspondent will note that for thin people who are pale and deficient in vitality the water grapes will be found most salutary. They are best taken alone at breakfast without the addition of any other form of food.
