456 SUMMARY OF CURRENT RESEARCHES RELATING TO 



gently over the mucous membrane. Cultures were made on ox-serum- 

 agar plates and on ordinary agar, both aerobically, and in an atmosphere 

 of hydrogen. The author found, in comparing the bacterial contents 

 of the anterior and posterior portions, that the numbers diminished 

 from before backwards, although the species did not vary. Constant 

 forms were Bacillus pseudo-diphtherim, Strepto-bacillus urethra, Staphylo- 

 coccus albus, aureus and citreus, Sarcina alba typica, alba atypica and 

 Uava, and Micrococcus candicans. Occasional forms were a vibrio, a 

 coccus negative to Gram, an influenza-like bacillus, and Bacterium 

 bruneum. The author concludes that (1) the normal urethra even in 

 its' posterior part contains numerous bacteria ; (2) the presence of 

 Bacillus pseudo-diphtherice and Strepto-bacillus urethral can become im- 

 portant in conditions of post-gonorrhceal urethritis and cystitis ; 

 (3) none of the obtained forms are pathogenic to animals ; and (4) it 

 is worthy of note that in none of the studied cases were typical 

 Streptococci or Bacillus coli communis found.
