“A well-spread board” should be described as one at which the youngest child (whose teeth are cut) may exercise his will without let or hindrance until, at the first indication of dallying, or “loafing,” over his food, it is evident that he has had enough; and at which the consumptive may eat without being tempted to overindulge, but, paying heed to the first intimation of satiety, rise from the table with the assurance of having performed an agreeable duty, in that he has eaten in quantity and quality, what he can digest and assimilate. The consumptive starves, not for want of food, but for want of digestion and assimilation. It is impossible to emphasize this fact too strongly. The _Scientific American_ of June 3, 1882, in an article entitled “Tubercle Parasite,”[28] considering Dr. Koch’s theory, says: “According to Dr. Salisbury, this disease (consumption) is one arising from ‘continued unhealthy alimentation, and must be treated by removing the cause. This cause is fermenting food and the products of this fermentation, viz.: alcoholic yeast and alcohol, vinegar yeast and acetic acid, carbonic acid gas, embolism, and interference with nutrition. Consumption of the bowels can be produced at any time in the human subject in from fifteen to thirty days, and consumption of the lungs inside of ninety days, by special, exclusive, and continued feeding upon the diet that produces them——that is, food containing starch and sugar in alcoholic and acetic acid fermentation.’” Dr. Salisbury had found this embryonic form of the vinegar yeast in the blood, sputa, and excretions of persons suffering with consumption. In the blood the plant forms masses by itself, grows inside the white corpuscles, causes the fibrin filaments of the blood to be larger in size and stronger, the red corpuscles to be ropy, sticky, adhesive, making small clots or “thrombi,” which become “emboli” or plugs, and block up the capillaries and blood-vessels. The growth of the vinegar yeast in its embryonal stage, combined with the mechanical interference with nutrition, causes abnormal growths in the substance of organs, called tubercle; and the concurrent inflammatory results, in addition to the chemical action of the vinegar or acetic acid, causes the death and breaking down of the organs invaded——the lungs, for example. That this is not opinion only is shown by the fact that over 246 swine were, at his instance, destroyed by feeding on farinaceous food in a state of alcoholic and vinegar fermentation, the vinegar yeast traced in the blood, found in the excretions, and 104 of the dead swine were subjected to _post-mortem_ examinations and their lungs found broken down and diseased as in ordinary consumption. The same experiment was tried on a number of men, “all healthy, and with no vegetations in the blood. They were given plenty of exercise in the open air,” but within three months these men had consumption of the lungs. “Certainly,” says the _Scientific
