Blood-agar-plate cultures made from these areasshowed staphylococci, green-producing streptococci and some gram-positivebacilli. The localizing power of the staphylococcus isolated from the urine andkidney of this dog was determined by intravenous injection into rabbits. Thetwo injected Avith the culture from the urine developed marked lesions of thekidney, and one slight lesions of muscles. One of the three injected with thekidney culture developed marked lesions in the kidney; the other two, slightlesions. The staphylococcus was isolated in pure culture from the kidney *-.*-??!: ^ ? ??•? ??•/#v^. Fig. 6.—Section of kidney of Dog* 2.
