182 PHYSIOLOGY OF THE BACTERIA. 
to the development of numerous micro-organisms, the 
most common form being Bacterium. 
The 20th of May, 1873, with a Pravaz syringe, I 
injected four drops of this liquid into the right ocular 
globe of a rabbit. Immediately afterward, the iris 
bulged forward, became clouded, and the pupil dilated 
irregularly. Asa result of this injection a terrible in- 
flammation was developed. On the 25th I note an 
intense conjunctivitis and a roughness of the cornea, 
from which the epithelium has disappeared at certain 
points. Upon the posterior surface of the cornea is 
a white cloud occupying the inferior part of the pupil- 
lary opening, more opaque in certain points and present- 
ing the appearance of a hypopyon; the iris was still 
bulged forward, tomentous, of a violet red color; pupil 
contracted. 
June 4, the iris is still bulged forward, so as nearly 
to touch the cornea; the crystalline lens is also pushed 
forward. 
June 5. By aspiration I withdrew from the vitreous 
a sort of membrane having the form of a whitish fila- 
ment. Upon examining this with the microscope, I 
recognized the presence of pus globules, cryptococcus, 
and bacteria. 
June 10. The ocular inflammation has disappeared, 
but a cataract remains. 
Exp. II.— The same as the preceding. When the 
syringe was withdrawn from the vitreous, into which 
four drops were injected, a chemosis occurred, result- 
ing no doubt from the fact that a little fluid was extray- 
asated into the sub-conjunctival tissue. Operation made 
May 25. 
29. Intense ocular inflammation, conjunctiva of a 
uniform red color; cornea clouded, of a pearl gray tint ; 
iris very red, tumefied. The animal seems to suffer 
much when it is examined.
