A.L.M. writes.--Our domestic servant, a girl aged twenty-four, is suffering from ulceration of the stomach and has had periodical attacks for the past six years. She has apparently, until she came to us, eaten and drunk very unwisely. She has been with us seven months and has been fed on a non-flesh diet since she came. For the last four weeks tea, coffee and cocoa have been forbidden, and as little sugar is consumed as possible. She had a very bad attack in August and we had to call in a doctor is we did not like the responsibility. He strongly recommended the hospital and an operation, which would ensure that there would be no repetition of the complaint. She decided to go and was there six weeks. After much experimenting there, inoculating and wondering whether it was tuberculosis, they operated and in due course she came back. We went to the sea for three weeks and shortly after our return the vomiting of blood and pains recommenced. After four days in bed she returned to light dishes, and a fortnight after another slighter attack came on, which in twenty-four hours. She takes hot boiled water five times a day. She suffers also from a horny skin on the palms of her hands, with deep cracks where the natural lines are. These periodically bleed. This skin exists also on her heels and the soles of her feet. Before and after, an attack this skin seems to be worse than ever. I mentioned the fact of the recurring attacks since the operation to the doctor and he seemed surprised and said the matter must be constitutional and there was no hope for her. My own opinion is that pure food will put her right eventually, and that these attacks will recur in diminishing force until the poisons are eliminated front the system. Her diet is at present as follows:-- _On rising._--Half-pint of boiled water (hot). _Breakfast._--Either Shredded Wheat softened in hot milk or breakfast flakes and cold milk: followed by either bananas or apples. Half-pint boiled water (hot). _Lunch._--Ordinary vegetarian cooked dishes, vegetables conservatively cooked, some fruit. Half-pint boiled water (hot). _Tea meal._--Wholemeal bread (Artox flour), usually non-yeast, nut butter. Lettuces and radishes when obtainable. Half-pint boiled water (hot). _Before retiring._--Half-pint of boiled water (hot). It has been shown by Brandl and other investigators that ulceration of the stomach can always be produced in animals by feeding them with an excess of sugar foods. The same thing applies to human beings, who, if fed with an excess of sweetmeats, sugar, milk or soft mushy cereals, will first contract catarrh of the stomach, which will ultimately deepen into a condition of ulceration.
