SO ENDS this further consideration of spider webs, and a prelude to the next weekend that largely deals with the subject of web geometry. Not only must webs be strong, and be composed of various silks, but they must also ensnare the prey with durable stickiness that does not dry out. The chemical manufacture and extrusion of these materials that polymerize outside the body from internal organs that operate at ambient temperatures and pressures is today beyond the capability of chemists; companies like DuPont and BASF have had to abandon this project.
