490 RECOGNITION OF BACTERIA. 



isms migrate into the organs from the intestine. If living bacteria are 

 injected into the abdominal cavity or trachea of cadavers, they can 

 very often be found in the organs after a time (C. B. xxiii, 418). 



After the autopsy the body is best burned. If this is not practica- 

 ble, the body is wrapped in coverings wet with sublimate and buried 

 at least 0.5 meter deep, and quicklime filled in about it.

(Illustrated w T ith an example. ) 



The case is one of eczematous conjunctivitis in which a 

 number of the bacteria occurring in diseased eyes are 

 present. Purulent or serous material removed from the 

 conjunctival sac or edge of the lid with a platinum loop is 

 made use of. 



I. Microscopic Examination (Smear upon Slide 

 or Cover-glass). 



(a) Stained with f uchsin, we see : 



1. Cocci, especially diplococci in heaps, usually dis- 

 tinctly "biscuit-shaped," many times within cells (per- 

 haps gonococci). 



2. Cocci, single or united in irregular clusters (probably 

 Micro, pyogenes). 



3. Short chains, of two or three links, of lance-shaped 

 cocci, some with capsules (probably Streptoc. lanceolat. ). 



4. Rods, larger or smaller, often very irregular in form, 

 staining in segments, ends rounded or pointed, often of 

 the size of cocci (true diphtheria, pseudodiphtheria, or 

 xerosis bacillus). 



5. Rods regular, rather thick, but small (perhaps coli 

 group). 



6. Rods, often in pairs, quite large, the ends not rounded 

 (perhaps, although at the time without spores, a bacillus 

 or Bacterium duplex).
