Ill 
hydrogen dioxide injection immediately on the very first appear¬ 
ance of discharge. The meatus should be closed and the solu¬ 
tion retained for five minutes. The injection should be used 
four to six times in twenty-four hours. This drug is only of 
value in the incipient stage. 
Cystitis, where pus is voided with the urine, often yields 
rapidly to injections of a' solution containing two ounces to the 
pint. 
Otitis media is treated by hydrogen dioxide solutions in vari¬ 
ous strengths from 6 per cent, upward. It is an almost indis¬ 
pensable agent in these cases. 
Bye diseases, where there is a purulent external inflamma¬ 
tion, are constantly being benefited by this agent. The Wills 
Bye Hospital, Philadelphia, uses a 50 per cent, strength of the 
so-called 15 volume solution. Blepharitis marginalis is quickly 
cured by touching the edges of the lids once or twice daily with 
a strong solution, taking care to avoid getting it into the eye. 
Ulcers of all kinds improve rapidly under its use, granula¬ 
tions are stimulated and surfaces freshened. For treating and 
cleansing venereal sores, as chancroids, etc., it is of great.service. 
Bmpyema, especially where there is from the first a stinking, 
sanious exudation following incision, is very satisfactorily treat¬ 
ed by washing out the cavity with a solution from one-half to 
full strength. 
Dr. Noble, of Philadelphia, commends this agent for cleans¬ 
ing the hands preparatory to abdominal operations when the 
skin about the nails has become horny and rough from frequent 
contact with antiseptic solutions. 
In appendicitis, the abscess cavity is cleansed with this solu¬ 
tion by many operators, in preference to any other antiseptic. 
Robert T. Morris, of New York, has laid special stress on the 
value of the peroxide in these cases. 
In follicular tonsilitis, the use of a spray, diluted just enough 
to prevent the smarting sensation, and alternating with this one 
of the alkaline antiseptic sprays, or gargles, is a very satisfac¬ 
tory procedure. 
' Diphtheria and all naso-pharyngeal inflammations where 
there is a pseudo-membranous and septic condition, have been 
treated very widely by means of this agent. I like the plan of 
Jennings in Detroit, who uses an irrigation of an aqueous solu¬ 
tion of one-eighth each of hydrogen dioxide and listerine. He 
throws the solution into the pharynx with an all-soft rubber 
syringe every one, two or three hours. The plan is an admir-
