136 THOMPSON YATES LABORATORIES REPORT 
In the first two cases, where the discharge was considerable, Koch-Weeks 
bacillus was observed in quantity. 
In three and four, where there was no discharge, one or two slender bacilli 
were observed after examining a large field. It was only possible to say that these 
slender bacilli resembled exactly the morphological appearance of Koch-Weeks 
bacillus ; in cases where the bacillus was with difficulty found no cultures could be 
obtained. 
Case five belongs to the series of six which was kept for a month under 
observation. The discharge in this case was almost wholly fibrin, only a few 
leucocytes and epithelial cells being seen ; in films of the discharge no organism could 
be detected. 
Case eight was examined four times at different periods in six months, and on 
every occasion a pseudo-diphtheria bacillus was obtained in pure culture ; its 
characters are given in Table IV (No. 5). This was the only occasion on which this 
variety of pseudo-diphtheria bacillus was isolated. 
A glance at Table II (page 135) shows that no organism occurs with sufficient 
constancy to justify a causal connection with granular lids. 
Also each organism isolated was inoculated on the conjunctiva of a rabbit and 
in no case did a granular condition result.
