Walnut Hills, Cincinnati, Aug. 23, 1883. Dr. N. S. Davis
—Dear Sir: My article in No. 5 contains an error of statement. The sentence referred to is on page 138, second column, and should read as follows: If aortic aneurism be eliminated, absence of abnormal precipitation of the carotid pulse is conclusive, in any case, of absence of an open state of the aortic valves. Yours truly,A. T. Keyt.
