pyogenic membranes. Is free from irritating or poisonous qual- 

 ities; it is injected into sinuses, abscesses, fistulous openings, ap- 

 plied to fresh wounds to prevent suppuration, used on the hands, 

 can be injected into tender places, such as the uterus in metritis, 

 etc. ; best in this case to dilute one-half with distilled water. 

 Used in canker of the ear in dogs, fistulous withers, quittors, etc. 

 Wash for sore throats, purulent ophthalmia, injection for sinuses 

 after trephining for nasal gleet, etc. Use dilute hydrochloric 

 acid 1 to 4 to stop fetid odor after trephining and to dissolve 

 necrosed bone. Every nail wound should be injected with perox- 

 ide of hydrogen. 



In Parturient Paresis, I would recommend a trial of Hydro- 

 gen Peroxide (Marchand's) as follows; inject slowly one-half 

 to one ounce into each quarter, then thoroughly and gently mas- 

 sage the parts. Repeat in 12 to 24 hours if necessary. 



Peroxide of Hydrogen should not be injected in cavities 

 where the free escape of the gas cannot occur and should not be 

 too long continued in deep wounds or where the cavity is much 

 larger than the outlet, as the expansion of the gas naturally 

 dilates the cavity and thus breaks down adhesive granulations. 



The drug is very useful in diagnosing the extent of punc- 

 tured wounds and long fistulous tracts. 



For this purpose inject a liberal quantity full strength and 

 immediately cover the opening with the finger; the expansion 

 of the gas causes a swelling which naturally indicates the length 

 or depth of the tract or puncture. 



This method may be used also as a guide for making de- 

 pending openings. 



The drug is usually used full strength and should not 

 be used in metallic containers or syringes. It tends to rust 

 steel instruments. 



Internally. — Is a powerful promoter of the appetite ; used in 

 gastritis, gastric flatulence, etc. ; can be given to dogs in from 

 15 ms. to 2 or 3 drs. doses; horses, ^2 to 2 or 3 ozs., diluted 

 with 2 or 3 times its bulk of water. When it comes ip contact 

 with pus it produces a frothy foam; as long as the foam comes 

 back yellow there is pus in it, but when it comes back clear or 

 white the pus is all out.
