There can be no question whether retention of fæces of itself can bring about scurvy; this is excluded by the marked instances of constipation frequently encountered among thriving babies. The majority of bottle-fed babies and a large number of the breast-fed suffer from a greater or less degree of constipation. On looking over our records of infantile scurvy from this point of view, and comparing them with non-scorbutic infants, we have not been able to note a characteristic distinction. Some of the infants had normal stools, others suffered from constipation, while the records of a great number showed occasional loose stools. Furthermore, in cases of latent or subacute infantile scurvy, it was of no moment whether a laxative was given or whether constipation was induced by means of opium. The report of the American Pediatric Society shows that the majority have had a similar experience; the bowels were regular in seventy-four instances, irregular in fifteen, constipated in one hundred and twenty-six, and diarrhoeal in seventy-seven. In this connection, it may be pointed out that the preparation termed "malt soup," the diet which in our experience has been most frequently associated with scurvy, is essentially laxative, and, on the other hand, that one of the most potent antiscorbutics is potato, which has no definite laxative property. It may be added, as noted elsewhere, that scurvy developed in infants in spite of their receiving cod liver oil or olive oil for long periods. It is evident, therefore, that the retention of fæces is not the essential factor in the etiology of scurvy. Its secondary rôle, especially after scurvy has developed, will be considered later in this chapter.
