Two inscribed offprints: 1. On the Time-Relations of the Excitatory Process in the Ventricle of the Heart. [Baltimore, 1880.] 8vo (234 x 159 mm). Offprint from The Journal of Physiology, Vol II, Nos 5 & 6. Original rose wrappers, some soiling.THE CLASSIC STUDY ON THE ELECTROPHYSIOLOGY OF THE HEART, INSCRIBED BY BURDON-SANDERSON. "These workers were among the first to study the action currents of the heart, and made the first records (with the capillary electrometer) of the minute electrical current produced by the beating of the heart" (Garrison-Morton 824).2. On the Electrical Phenomena of the Excitatory Process in the Heart of the Frog and of the Tortoise, as investigated photographically. [Baltimore, 1884].8vo (238 x 163 mm). 8 folding plates. Offprint from The Journal of Physiology, Vol IV, No 6. Original rose wrappers, leaves unopened. Soiling, ink notations to covers, some chipping to spine, started.INSCRIBED BY BURDON-SANDERSON TO FRONT COVER. In their history of electrocardiography, Burch and DePasquale reproduce illustrations from this classic paper and note that they were the "first undistorted tracings of the electrical activity of the heart" (Burch and DePasquale, A History of Electrocardiography, San Francisco, 1990, p 102).
