The addition of thyroid tablets, gr. v once daily, has so far produced no appreciable effect.A d;efinite remission followed the week in wlhich tlle patient was in hospital on a meat-free diet. But-in spite of. limiting -subsequently the amount of meat and meat extracts in the diet, and ensuring regular action of tlle bowels,-the attacks continue to recur at very variable intervals.
