To the Editor:
—In an article by Dr. Harry Keil entitled "Dermatomyositis and Systematic Lupus Erythematosus: II. A Comparative Study of the Essential Clinicopathologic Features," in the August issue (Arch. Int. Med. 66:339, 1940), the author gives me the credit (in footnote 4, on page 342) for the term "wire loop lesions" used to describe manifestations observed in lupus erythematosus.Dr. G. Baehr first observed the so-called "wire loop lesions" in the glomeruli in a case of lupus erythematosus in 1921. The autopsy protocols of the Mount Sinai Hospital in that year record the fact that he had already determined that the peculiar material in the capillary walls was not related to amyloid. Shortly after I joined the staff of the Hospital in 1927 as pathologist, he discussed with me his observations of glomerular and widespread vascular lesions in connection with a patient who came to autopsy about that time.
