To the editor: The letter of Dr. Freeman (Ann Intern Med 77:661-662, 1972) that replies to comments about milligram/milliequivalent appears again to have fallen into the same error: "if one asks the physician how much sodium chloride (not sodium, as originally written) is in a litre of normal saline, he answers 154 mEq not 9000 mg!"
However, 9 g of sodium chloride (in solution with 1 litre of water!) contain 154 mEq of each ion, therefore 308 mEq of sodium chloride, all common knowledge to everyone. Perhaps it would be better to leave the "ion" where it belongs: in solution
