2. An endurable quantity of hexamethylentetramine taken prophylactically weakens a fatal poisoning to such an extent that it can be overcome without treatment. c. t.=2,275.
3. Nonfatal but nevertheless oedema-producing poisonings are made positively ineffective by intravenous application, and are weakened by oral application, c. t. 250 to 1,980.
4. The oral application of hexamethylentetramine is no longer effective against phosgene poisoning of a c. t.=5,400, the intravenous injection, however, weakens the effect to such an extent that the protected subject is able to overcome a lung oedema.
5. The dosis letalis minima (minimum lethal dose) based on these experiments cannot yet be determined with certainty. One c. t. of 2,275 resulted in the death of one experimental subject, and the second developed second degree oedema of the lungs which was cured.
6. Some of the protected experimental subjects who did not develop oedema of the lungs remained completely healthy, others suffered from slight bronchitis with a brief fever. In every case they recovered without treatment.
