The determination of the Opsonic Index has become so important that these incubators have been made to meet the demands for an apparatus in which twenty pipettes can be incubated at one time, and so that any tube may be examined during the progress of the experiment without changing the temperature of the others. There are twenty tubes for opsonic pipettes and an extra tube. The tubes may be easily removed when desired by means of a key which accompanies the incubator. On top there are eight tubes, 22 mm. in diameter, for test-tubes. Each is provided with a nickel-plated cap. The incubator is supplied with thermometer, thermo-regulator, and a two-flame burner, with wire guard. opsonins vi^hich induce phagocytosis. It is furthermore possible to increase the activity of these agents artificially. All three agents are specific in nature as already stated. Ehrlich has attempted to explain the phenomena of immunity according to his receptor or side chain theory (Seitenketten- theorie). This theory, w^hich is rather complex and highly technical, was first used to explain cell metabolism. Hinman's version of the side chain theory is very simple and we give it as follows: As applied to immunity the basis of the theory is the conception of the duplex nature of 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 orig
