Excerpt from letter from Harriet L. Hardy, M.D to Manfred Bowditch, October SO, 195S: We haye now treated three cases' of chronic lead poisoning with Ca EDTA and are much impressed by its usefulness and, as far1as we can tell, its freedom fbom toxic effects. The last case showed that the drug changed the man's excretion from ,55mg./liter to 17.80 mg./liter, on the second day of therapy. What do you think of that? If the man agrees, we are now going to put him on the famous Ward 4 and do careful metabolic studies to tell us more about calcium balance in this treatment. K F 0006177 N 7515
