178 BACTERIA IN THE SPUTA 



cus, relatively frequent, was first found by Koch and Gaffky in the 

 cavities of a consumptive subject ; it is more frequent in tubercu- 

 losis. Biondi found it in three cases out of five. It is in the 

 shape of cocci disposed two by two or four by four ; with gelatin- 

 ous matter interposed, it does not liquefy the gelatine. White 

 mice and guinea pigs inoculated with its cultures die in from three 

 to ten days; those inoculated with sputa perish in from four to 

 eight days. Their blood and their organs are infested with micro- 

 cocci. 



Fungi of Biondi. -This investigator has isolated from the 

 mouth five different pathogenic bacteria, including the Micrococcus 

 tetragenns above-mentioned. The four others are : — [e) a Bacillus 

 salivarius septicus, rather frequent ; (f) a Coccus salivarius septicus, 

 obtained in a single case only from a woman affected with a serious 

 septicaemia in her confinement ; (g) a Sti-eptococcus septicus^ similar 

 to that of erysipelas phlegmon and puerperal Metrilis ; (h) a 

 Staphylococcus salivarius pyogenes^ found once in the sputum of a 

 scarlatinous quinsy. 



The Fungi of Miller.— After many cultures and inoculations 

 from buccal liquids and dental gangrenous pulp, Miller observed 

 more serious effects from the inoculations of the pulp, even 

 in comparison with inoculations of cultures of the same pulp. 

 The effects were varied in different animals and according as the 

 inoculation was made under the skin or the peritoneum cavity. 

 The pathogenic fungi isolated by the author were : — (r) a Micro- 

 coccus Gengivce pyogenes (Fig. 99 of Miller), obtained from alveolar 

 pyorrhoea cocci that did not liquefy the gelatine ; {k) a Bacterium 

 Gengivce pyogenes (Fig. 100 of Miller), found with the former, in 

 the shape of bacteria four times longer than broad, apt to liquefy 

 the gelatine ; (I) a Bacillus Dentalis viridans (Fig. loi of Miller), 

 obtained from the decayed roots of teeth, in bacteria of irregular 

 forms; (m) a Bacillus FulpcB pyogenes [Y'lg. 102 of Miller), obtained 

 from the gangrenous pulps, in bacilli, frequently irregular, isolated, 

 linked together, or in small chains, even with eight articulations, 

 apt to liquefy the gelatine.'" 



We cannot further describe these culture experiments. We
