R. dead eggs caused Mr. Kelly to consider not picking out the few living embryos. The eggs developed in 50 cc. of sea-water, fertilization hav- ing been delayed for half-an-hour in the case of about two dozen of the eggs (fig. 3). In one of his earlier papers, Stockard mentions a case of incomplete diprosopus with three eyes and an additional lens (Stockard '00), but does not mention any factors other than anesthetic. Mr. Kelly's specimen showed four well-developed eyes. Sections were made and the specimen was found to be like many other doul)le-headed monsters (Oemmill '00, '03). It possessed two mouths and throats, but only one heart, and had twin brains united at the optic Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bardeen, Charles Russell, 1871-1935, ed; Boyden, Edward A.
