Preliminary test A:
Preliminary test to determine the surest and most practical way of infecting human beings artificially. Five experimental subjects received intramuscular and subcutaneous injections of vitelline membrane diluted 1:25 with an emulsified Rickettsia-Prowazeki strain from the Robert Koch Institute in doses of 1 cc. Infection was not possible.
