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. As a 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 syringe was withdrawn from the vitreous, into which 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 extrav- 

 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.
