Comparative study of the rapidity with which Organisms artificially 
introduced are removed from the healthy and diseased conjunctivae 
Method. — A pure culture of some easily detected organism was inoculated 
on the conjunctiva. A small quantity of lachrymal fluid was taken after the lapse of 
varying intervals of time by means of a sterile cotton-wool swab, which was smeared 
well over the surface of agar. 
Experiment I.--A loopful of sarcina lutea was introduced into a perfectly 
healthy rabbit's conjunctiva. The organism had entirely disappeared in 
eighteen hours. 
Experiment 2. — Two loopfuls of bacillus coli were introduced into the healthy 
conjunctival sac of a rabbit. The disappearance was not so rapid as 
with the sarcina. In twenty-four hours eighteen colonies were grown, 
and in forty-eight hours, six ; at sixty hours the organism was no longer 
present.
