On February 9th, 1914, she returned to the Hospital and was placed under medical treatment, with vegetarian diet. There was then an ulceration along the line of incision, from the second to the fourth rib, with many nodules around it, averaging a third of an inch in diameter, raised and reddened. The liver extended two inches below the edge of the ribs, with a hard and nodular margin; the right arm was enormously swollen and helpless. When she left the Hospital, June 20th, 1914, the ulcer had entirely closed, many of the cutaneous nodules had entirely disappeared, the arm had returned to normal size, like the other, by measurement, and the liver had retracted to a trifle below the margin of the ribs, with hardly any nodules to be felt. The treatment had included twenty-five X-ray exposures, from 8 to 10 minutes each, about twice a week, over three areas each time. While in the Hospital careful laboratory investigations were made, according to a definite schedule. The _blood_, studied weekly, maintained a hæmoglobin of 80+ for over two months, then fell a little, and again rose. The erythrocytes were 3,262,000 on entering, and rose within two months to 4,282,000, then fell a little and rose again to almost 4,000,000: the leucocytes were 9,000 on entering, and fell to 5,200 just before leaving, the poly-nuclear 69 per cent. on admission, fell to 60 per cent., and again rose a little, and the proportion of the other forms remained about normal. The _urine_, volumetrically analyzed every three days, was kept a little below the normal acidity, and the specific gravity a little low, with a free daily amount of excretion, largely by Bethesda water: in spite of the vegetarian diet the urea excretion was not much below normal, and sometimes above, the chlorides were diminished, owing to the rather small amount of food taken, the phosphates varied a little above and below normal, there was never any indican, and the sulphates averaged a trifle below normal. The _saliva_, tested before and after each meal, was acid at first, but became neutral and alkaline off and on. The _weight_, taken weekly, fell a little from the first, but maintained a good level, and rose a little before she left the Hospital. This was a very difficult patient to manage, as she was a very ignorant Polish woman, who often rebelled at the diet, and wearied of the routine and restrictions imposed; she left the Hospital June 20th, 1914, against my wish, but with as great a change in her physical condition and disease as could be imagined, after about four months and a half treatment, carried out under disadvantageous circumstances. One other case, seen recently, where the disease was recurrent after three operations, deserves mention, although it will be some time before any decisive result can be reported.
