GONORRHGA. 
Nothing is more certain than the fact that gonorrhcea 
can only be diagnosed by bacteriological methods ; and 
every practitioner is very strongly urged to practise 
himself in these methods and to employ them in all 
cases. Leaving out of account the confidence which 
the certainty of a correct diagnosis inspires, there is 
always the possibility that legal questions may arise, 
and a practitioner who made a diagnosis of gonorrhcea 
without employing the only means by which that dis- 
ease can be diagnosed would make a poor show in 
cross-examination. Lastly, a bacteriological examina- 
tion will often tell us that the disease is merely lying 
latent and is still infective when apparently cured. 
The gonococcus chiefly affects mucous surfaces; the 
urethra in the male, the urethra and cervix uteri in the 
female, and the conjunctiva in both sexes. These are 
the regions in which the primary lesion usually occurs, 
and it may extend by continuity to more distant parts. 
In the male it may involve the prostate, the vesicule 
seminales, and the bladder. It is doubtful whether 
gonorrheeal epididymitis is due to this organism or to 
another. 
In the female the inflammation of the urethra may 
extend to the bladder. The inflammation of the cervix 
may extend to the mucosa of the uterus and thence to
