This paper reports upon some work carried out in 1967 in close collaboration with Professor Piccardi at the Second Dermatological Clinical of the University Medical Centre in Vienna (Director: Professor Wiedmann). During about one year I studied the differences in blood coagulation time observed during tests carried out daily at the same time and the same locality. The blood used for the test was always my own blood. Three series of tests were carried out: The first test was carried out at 8.30 hr in the catacombs of the St. Stephan's Cathedral in Vienna which were located about 14 metres below the Cathedral and consisted of a compact sandy soil. The roof of the Cathedral, burnt down during the Second World War, was reconstructed with cross beams of steel which served as an important metal shelter with electromagnetic screening effects. The second test took place in my laboratory at the Serological Dermatological Clinic at 9.00 hr; a small ground floor building in the middle of the garden, the roof of which is not covered with metal. The third, test took also place in my laboratory at 14.00 hr. The coagulation time differed considerably at both localities. In the catacombs, a very sheltered place, the coagulation time was 9 min, whereas in my laboratory, a less sheltered place, it lasted only 3 min at 9.00 hr and 2 min at 14.00 hr. In the catacombs the histograms of the coagulation time values showed a distribution of Gauss, in the laboratory a distribution of Poisson with a prevalence of the shorter times was observed. It is evident, therefore that if certain unknown external forces in the non-screened environment are able to affect freely the coagulation of the blood, the coagulation is quicker and the blood coagulation time shorter, whereas if the exterior influences are reduced the coagulation is slower and the coagulation time is longer. The fact that I observed in my laboratory a shorter coagulation time at 14.00 hr than at 9.00 hr, may be due to the daily rhythm of the blood properties. It is well known that they are different in the morning and afternoon.
