On page 58 of the article "Stenosis of the Infundibulum" by Drs. Maurice Lev and Sidney Strauss, in the July issue (Arch. Int. Med.70:53, 1942), the second sentence of the section entitled "Comment" should read "When the patient was first seen, ten years before death, a systolic murmur was heard at the base of the heart." Similarly, in the last paragraph under this heading, "the base of the left lung" should read "the base of the heart."
In lines 17 and 21 on page 58, "the P wave in lead II" should read "the second pulmonic sound."
