An investigation to determine the precise factors in skimmed milk which are responsible for initiating the cure of kwashiorkor has been reported elsewhere. As part of this investigation a series of cases were treated with skimmed milk, some with and some without a vitamin supplement. It was shown that the vitamin supplement made no significant difference to the rate of cure. In a limited number of cases an imported dried skimmed milk appeared to be superior to the locallymade product. To clarify this observation a larger number of cases has now been brought into each series. In addition a further group has been treated with fresh skimmed milk containing a protein and vitamin supplement. In this communication we refer to the relative effectiveness of these 4 skimmed-milk formulae in the initiation of cure of this syndrome.
