Our best course is to combat the clouded cornea some hours af¬ 
ter the corrosion has taken place, although at the same time the 
application of the ice must also take place. To the above pur¬ 
pose I have found Hg. O to be the best means ; but we must not 
use the same until three or four hours subsequent to the applica¬

States, is a problem which time only will solve, but which depends 
much on the successful execution of the sanitary measures which 
have been taken in New York, New Jersey, Pennsylvania and 
other States where the disease is known to exist. 
For those amongst us who know the disease, who have seen it 
here and abroad, who have witnessed post mortem examinations, 
who have followed the history of many well authenticated cases,

tend over our vast continent. 
However, as shown by a card reprinted in the February num¬ 
ber of the Review, there are in New York a few who deny the 
existence of that disease, even in that most important and dan¬ 
gerous of centers of infection at Blissville, L. I.; and though the 
statement then made was to a certain extent contradicted by a 
letter which we printed in our March number, one of the incred¬ 
ulous wrote to the Medical Record a letter attempting to show 
the error which was committed by the majority of the veterin¬ 
arians, who had visited and seen post mortems at Gaff, Fleischman
