114 BACTERIOLOGY OF THE EYE 



(6) 42 cases of purulent conjunctivitis : 



24 containing Gonococcns. 

 8 Koch- Weeks bacillus. 

 1 Staphylococcus. 



1 Streptococcus. 



2 various indeterminate organisms. 



2 none. 



(c) 310 cases of catarrhal conjunctivitis : 



185 containing Diplobacilli. 

 10 Koch-Weeks.

11 none. 



(d) 33 cases of conjunctivitis neonatorum : 



22 containing Gonococci. 

 4 Pneumococci. 



3 Koch-Weeks. 



2 various bacteria. 

 2 nothing. 



Examination of a secretion smear which, indeed, determines the utility of bac- 

 teriological examination in practice gave a positive and useful result 245 times in the 

 365 cases ; 15 times the result was quite negative, and 100 times individual organisms 

 were seen (especially Staphylococci), but the result was indeterminate. From 

 these results Gonin rightly affirms that such an examination is valuable in 

 practice. 



The table given above further shows that diplobacillary conjunctivitis is very 

 frequent in Lausanne, the other forms being less important. 



With regard to the classification of conjunctivitis, Gonin agrees with Morax in 

 the view that, respecting conjunctivitis due to Koch- Weeks bacilli, to Gonococci, 

 and to Diplobacilli, the bacteriological designation is correct and unassailable, for 

 these organisms, as a rule, are alone the causes of the disease. For the others, in 

 which disposition, etc., is of more importance, a clinical designation must be com- 

 bined with the bacteriological. 



Pollock examined 236 cases of acute muco-purulent catarrh, and found : 



177 containing Koch-Weeks. 



9 ,, Morax I>iploba,cillus. 

 6 ,, Pneumococci. 



2 ,, Gonococci. 



1 ,, Gonococci+ Koch- Weeks. 



6 ,, Staphylococci. 



4 ,, indeterminate organisms. 

 28 negative. 



69 cases of subacute catarrh : 



I containing Koch-Week?. 

 51 ,, Diplobacilli. 



3 indeterminate. 

 8 negative.
