Prescribes "syrup of phosphate of iron". Requests a urine sample.

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—

- f1 4666.f1No 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 ). 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.
- f2 4666.f2CD evidently took phosphate of iron in pill form.
- f3 4666.f3Jenner had advised CD to drink little water when he first began treating him in March (see letter to J. D. Hooker, 13 April  and n. 6).
- f4 4666.f4For Jenner's last recorded examination of CD's urine, see the letter from William Jenner, 14 August 1864.
- f5 4666.f5See letter from William Jenner, 21 November 1864.
- f6 4666.f6Jenner had prescribed a combination of antacids, including chalk, magnesia, and carbonate of ammonia, in March (see letter to J. D. Hooker, 13 April  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).
