_The prevention of infantile scurvy_, especially in its rudimentary form, is of great practical importance, because of its frequent occurrence. There is no question but that breast milk and raw cow's milk furnish sufficient antiscorbutic vitamine, but there is a difference of opinion as to whether pasteurized milk, or milk that has been brought just to the boiling-point, or even sterilized milk, is adequate in this respect. Much of this divergence of opinion is due to the fact that the various clinicians have not considered or stated the quantity of milk which they have found sufficient to protect, and also because milk itself differs in its antiscorbutic value according to its freshness and probably also according to the fodder of the cows.[52] Without entering once more into a discussion of this question, it may be stated that unless the cow's milk is raw, the infant should receive additional antiscorbutic foodstuff. Moreover, this supplement to the dietary should be made as soon as possible, so as not to allow the vitamine deficiency and inadequate diet to exist for even a short period. In our experience there is no contra-indication to the giving of orange juice or of strained canned tomato, the two antiscorbutics with which we have had a large experience, to babies one month of age or even younger. The common practice, however, is to wait until the infant is five or six months of age, which certainly must allow a rudimentary scorbutic condition to develop. At the age of a month one teaspoonful of orange juice may be given; it should be diluted with water and sugar added if it is tart. This may be administered notwithstanding the fact that a baby has a tendency to looseness of the bowels, as orange juice, as recently pointed out by Gerstenberger, has practically no laxative action. Occasionally babies regurgitate orange juice, but the reaction usually ceases after a day or two. If it does not, a small amount of an alkali--for example, limewater or sodium bicarbonate--may be added just previous to feeding; in this state the juice will be better tolerated.[53] The amount of orange juice should be increased so that when the baby is three months of age it receives one tablespoonful.
