Mrs. Y., at the mid-century; history of mucous colitic and liver trouble; complained of spasmodic abdominal colic or gripes, < on the left side, preferred heat to cold, and liked pressure, though did not double up. Colocynth was of no avail. Magnesia phos. relieved temporarily but the attacks recurred. No diarrhoea, very few symptoms. Finally she said, “In these attacks I feel as though my stomach hit my backbone.” I asked her to try stretching during the pain and she found it agreeable. Wassermann and blood count negative. Stools tended to be in little black balls. Plumbum 1m, one dose, produced rapid improvement and the colics, which had been coming every day or two for four months, have now been absent for five weeks.
