My dear Sir
You may take carbonate of ammonia with Horseradish. But had better not take any other alkali till I have again had the urine analysed— You are not to take any magnesia— With reference to the ph. of Ir. & ph. acid I would advise you not to resume them at present— remain without medicine till we see how you are ie how far you are able to digest—sleep—&c—unaided by drugs— Do not resume the evil habit of drinking great quantity of fluid— Keep all rules but leave off medicine—
Yours very truly | W
