Among the diseases which have been attributed to a vitamine deficiency are "war or hunger edema," sprue, the "mehlnaerschaden" of infants, and the "exudative diathesis" described by Czerny and Keller. Future investigation will disclose whether any of these disorders belong in the group with scurvy. The _hunger edema_, noted in the late war and in previous wars, seems to be a complex condition, quite dissociated from scurvy, as many of the sufferers consumed comparatively large quantities of potatoes or other vegetables. The "_mehlnaerschaden_" resembles scurvy and the other vitamine disorders in its tendency to produce hydremia and susceptibility to infection. It also develops in spite of a liberal supply of antiscorbutic foodstuff in the dietary. As its name implies, it comes about on a diet containing large quantities of carbohydrate, of the cereal paps so commonly fed to infants. It is conceivable that an unbalanced diet of this kind may not provide a sufficiency of all the vitamines. It does not seem probable that _exudative diathesis_, a term which implies a predisposition to develop exudations or denudations of the skin and mucous membranes, is the result of a lack of vitamine. This condition does, however, predispose to scurvy. The association was very evident in the group of cases reported by Hess and Fish in 1914. It is not without significance that the blood-vessels in exudative diathesis also show a decided weakness, an increased permeability, as judged by the "capillary resistance test." In both scurvy and in exudative diathesis eczema and petechial hemorrhages are encountered. There may be _nutritional diseases due to an excess of food_ rather than to a deficiency. A superfluity may be harmful by hindering the proper utilization of the food, or may possibly lead to the formation of deleterious products. Disturbances of this kind do occur. For example, it is by no means uncommon for an infant which has been overfed with milk to show the typical signs of rickets. Young guinea-pigs which are fed liberal amounts of cow's milk develop a disease characterized by fragility of the bones. The experience of Lubarsch, who produced osteogenesis imperfecta in rabbits by means of a diet consisting mainly of liver, or adrenal gland, is of interest, especially as this condition did not come about when they were fed muscle tissue.
