They may settle in the heart muscle, but degenerate there without continuing their development. The muscles particularly favored by the worms are those of the dia- phragm, ribs, larynx, tongue and eye, which, as noted by Staubli, are among the most active muscles and the muscles with the richest blood supply and largest amount of oxygen. According to Flm-y trichinae have a high glycogen content, and probably subsist on the glycogen stored in the striped muscles; in fact the abundance of glycogen may account for their location in these 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 Chandler, Asa Crawford, 1891-.
