IO2 BACTERIOLOGICAL DIAGNOSIS. 



may be due to gonorrhoea, chancre, soft sore, or to a 

 non-specific balanitis, a similar method is adopted, but 

 here many ,6.1ms should be taken, as a prolonged search 

 may be required. If the patient suffers from a slight 

 discharge in the early morning the best plan is to give 

 him two clean slides. These are to be smeared across 

 the meatus whilst wet with the discharge and allowed 

 to dry. 



In the female it is necessary to obtain the pus directly 

 from the urethra ; it may be expressed by the finger in 

 the vagina. The first drop should be rejected. 



If the patient is suffering from cervicitis or endo- 

 metritis the pus should be taken direct from the cervix, 

 a speculum being used. 



It is absolutely necessary that you should spread the 

 films at once, even if you are having the examination 

 made at a distance. It is next to useless to send pus 

 dried on linen, cotton-wool, a Volkmann's spoon, or 

 even in a thick layer on a slide. The diagnosis may be 

 made from material sent in this way, but the difficulties 

 are much greater, and in some cases the results are less 

 certain. 



Preparation of films from conjunctival pus presents 

 no difficulties. The same is true of pus from the tubes 

 or other internal regions, whether it is exposed by 

 operative interference or at a post-mortem examination. 



Instructions for the examination of the blood are 

 given subsequently. A considerable number of films 

 should be taken, as the cocci are present in but very 

 small numbers. 



The urine may be examined in the female if a local 

 examination is not considered advisable, or in the male 

 to obtain evidences as to whether the disease is cured 

 or not. The morning urine should be examined. It
