1. The occurrence of an exalted strain of rabies virus has been recorded and a definition given of virus de rue renforcé.
2. The characteristics of exalted virus have been examined in respect of incubation time, fixation rate and absence of Negri bodies.
3. An adequate classification of street virus strains has been suggested.
4. Cross-immunity experiments have been carried out and, as a result of cross-protection tests and of crossed serum reactions, identity of exalted virus with the classical strain has been established.
5. The employment of autogenous and polyvalent vaccines has been shown to be unnecessary in anti-rabies immunisation.
