It should be said that infection with salmonella typhi murium is a very serious disease in mice and a handful of cells is practically enough to cause death. By the twenty-fifth day of observation practically all the control animals had died. Among the groups exposed in the pyramids 35-40% survived. There can be no doubt that this was connected with the time spent in the pyramid. There was no other reason; the more so, since this was not one but several groups of mice. Factors of the natural resistance of the organism are undoubtedly at play here. It may be changes is cellular immunity and humoral immunity. The investigation of those factors requires very careful and serious research which we were not able to carry out.

We were very surprised by the result we obtained, because to get a 40% survival rate in mice infected with a fatal dose of salmonella typhi murium is very difficult. It is important to stress that the mice were not given any chemical substances or medication; there were no factors that might act perhaps in one way, perhaps in another. And so we have established that the pyramid itself affects the living organism. Now we need too study the mechanism by which it does so..."
