My dear Sir
The preparation to which you refer is ``Syrup of Phosphate of Iron''— I think that as the turbidity continues you may find benefit from taking after each pill—10 drops of dilute phosphoric acid in water—
I would not advis<e> < > to drink more water < > The Phosphoric acid (if <as> I suppose the turbidity of urine is as it was when I last saw it) will diminish & not produce the deposit.
I think you had better let me have a bottle of the urine & I will have it analysed—
Yours very truly | W
<Co>ntinue the phosphate <of> Iron.
Is the urine alkaline when passed? if so you must omit the potash from magn. soda & potash powder—

No letter from CD to Jenner on syrup of phosphate of iron has been found; however, CD had recently learned from Mary Elizabeth Lyell that dyspeptic symptoms might be relieved by the preparation (see letter to Asa Gray, 29 October [1864]). On syrup of phosphate of iron, see British pharmacopœia 1864, pp. 334--5, and Royle and Headland 1865, p. 156. For Jenner's discussion of CD's use of phosphate of iron, see the letter from William Jenner, 15 October and n. 2. - +

Jenner had prescribed a combination of antacids, including chalk, magnesia, and carbonate of ammonia, in March (see letter to J. D. Hooker, 13 April [1864] and n. 6). Potash was an alkali used in the treatment of dyspepsia and gastric acidity (see Beasley 1865, pp. 392--7, and O. D. Owen 1868, p. 538). - +
