Sedimentation pictures (a) with photometric records (6) for the hemo- cyanin from Limulus polyphemus at pH (s2o = , , , and ); centrif- ugal force 120,000; time between exposures 5 mioutes. Busy con canaliculatum, Helix pomatia, Helix arbustorum, Helix nemora- lis, Helix hortensis, Limax maximus. They show extremely varied stability diagrams and a great number of dissociation products. The main component has a sedimentation constant of about 100. In blood from two of the animals, Busy con and Limax, a higher component with the sedimentation constant near 130 is found. All, except Neptunea, show a dissociation product with a sedimentation constant of about 60. Very often a component with sedimentation constant of approximately 16 is found and the final alkaline dissociation products have sedimentation constants around 11. It is also striking that the four kinds of Helix have different stability diagrams, so that each of them could be characterized 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 Lillie, Frank Rattray, 1870-1947; Moore, Carl Richard, 1892-; Redfield, Alfred
