iui orange-yellow sediment. On potutoes and blood serum a similar 

 orange-yellow culture grows luxuriantly. They may also form 

 colourless growths in sub-cultures, and are then indistinguishable 

 from Staphylococcus pyogenes albns. The cocci do not cause any 

 septic odour in pus, nor does any gas develop. Albumin is con- 

 verted b}- their action into peptones. 

 They produce rapid ammoniacal fer- 

 mentation in urine (Shattock). 



The micro-organisms injected into 

 the pleura or knee of a rabbit produce, airait/ \.^ 

 as a rule, a fatal result on the following " V"^

 ally dies of severe phlegmon. If injected 

 into the knee of a dog, suppuration 

 occurs, followed by diusintegration of the 

 joint. Injected into the peritoneal Fig, 84.— Pus with Staphylo-

nitis, and introduced into the jugular 



vein they produce septicaemia and death. When a small quantity of 

 a cultivation is introduced into the jugular vein after previous fracture 

 or contusion of the bones of the leg, the animal dies in about ten days, 

 and abscesses aie found in and around the bones, and in some cases in 



the lungs and kidneys,

Garre caused sup- 

 puration by inoculating 

 a pure-culture in a 

 wound near his finger 

 nail. Bockhart suffered 

 from several pustules 

 after vaccinating his 

 arm with a pure-culture 

 suspended in salt solu- 

 tion, and Bumm gave 

 himself a hypodermic 

 injection of a pure- 

 culture and produced 

 an abscess. This micro- 

 organism is practically ubiquitous. It has been cultivated fi'om 

 the skin and mucous membranes and secretions of healthy persons, 

 and it occurs in the air, in soil, in dust, and in water, and in
