dacryocystitis bacterin therapy may obviate surgical 

 extirpation of the lachrymal sac. 



Corneal Ulcer and Hypopyon. — The Diplococcus 

 pneumonke, the Streptococcus mucosus, the Strepto- 

 coccus pyogenes, the Staphylococcus, the Gonococcus 

 and Tubercle bacillus have been identified. Autog- 

 enous bacterins prepared from the pneumococcus 

 and streptococcus in cases of ulcus serpens of the 

 cornea, with and without hypopyon, notably in one 

 instance in which panophthalmitis threatened com- 

 plete destruction of the eye, have produced incredible 

 results (Fig. 55). Care must be observed not to 

 employ too small dosage in the treatment of these 

 affections. The initial inoculation should be at least 

 100,000,000 bacteria. 



Iritis and Uveitis. — Here as in corneal ulcer the 

 same organisms are found at work. If the infecting 

 bacterium be determinable the results are invariably 

 excellent. Especially noteworthy is bacterin therapy 

 in gonorrhceal involvements. In these conditions, as 

 in practically all gonococcic complications, practi- 

 cability demands that a polyvalent stock preparation 

 be employed. 



Otitis Media and Mastoiditis. — An extensive array 

 of bacteria as the Streptococcus, Staphylococcus^ 

 Pneumococcus, Colon bacillus, B. proteus vidgaris, 

 B. lactis aerogenes, B. pyocyaneus, B. fluorescens, B,
