 and inactivity of the pupil is a constant symptom.

 be slight or severe, and may have general symptoms of

 blindness. Any condition causing vascular turges- 

 ■cence may cause gout, rheumatisin, fever. The use of 

 atropine has caused it. Prognosis is always bad. I 

 had the pleasure last year of showing the class a case 

 of Glaucoma secundarium in one of the clinics. One of 

 the patients from the Broadway car stables was 

 pointed' out to me as having an interesting eye, and so 

 it was. Secundarium means increased intra-ocular
