54 VETERINARY SURGICAL THERAPEUTICS. 
Chloride of zinc, used by old surgeons for the treatment of wounds 
of a bad nature, is a powerful antiseptic. In concentrated solution 
(5 per cent) it rapidly destroys most of the spores (Koch), but is 
caustic. Solution of 1 in 10 is advantageous to disinfect fistula, 
abscesses, and suppurating or septic wounds. Socin’s paste (50 
parts of oxide of zinc, 50 of water, 5 or 6 of chloride of zinc), recom- 
mended in Veterinary Medicine by Cagny, forms for aseptic sutured 
wounds a protective varnish which may be used for dressing. It is 
especially used for wounds of the head and of the superior parts of 
the trunk. : 
Potassium permanganate is also a good antiseptic. Free from all 
toxicity, it owes its microbicide properties to the oxygen that it gives 
out. Without irritating action upon tissues, it can be used on all 
wounds, specially those of the mucous membranes. Soluble in 
water in all proportions, it is easy of application. In solution of 1 
to 1oco it is advantageous for disinfecting the mouth, the nasal 
! “ge . “ys 
cavities, the vagina, rectum and the wounds of cavities (serous). 
The strong solution is utilized (10 in 100) for injected wounds and 
for the asepsis of the hands. To remove the discolotation that it 
leaves, it is sufficient to dip them into a solution of bisulphite of 
sodium (10 in 100), to which is added a few drops of chlorhydric 
acid. 
Biniodide of mercury, whose germitide power is reported to be 
equivalent to thirty times that of corrosive sublimate, is used in 
solution of 1 in 10 or 20,000 for the disinfection of the ocular and 
uterine mucous membranes. It is not irritating to the hands or to the 
edges of wounds, and it does not injure instruments. 
fodoform, used for a long time now in the treatment of wounds. 
and ulcers (Demarquay, Lallier, Besnier, Féréol) is a costly antisep- 
tic. Its action is slow, but lasting. Both antiseptic and analgesic, 
it quickens cicatrization of wounds, interferes with the decomposi- 
tion of fluids that they secrete, and diminishes the soreness, A 
small quantity sprinkled upon bleeding tissues before they are 
brought together, does not prevent immediate union. Laid, even 
in thin layer, in wounds with loss of substance, it keeps them in an 
aseptic state for five, six or seven days, forming a kind of reserve for 
constant disinfection. (Forgue and Reclus.) Employed in large 
quantities upon recent wounds, on subjects provided with adipose 
tissues, principally obese dogs, it may be dissolved by the bloody 
secretion, by the fat, and give rise to intoxication. Its inconveni- 
ences for veterinary use are its disagreeble odor and its comparatively 
high price. It is generally applied as a fine powder, but sometimes 
under other forms. The most used preparations are : 
lodoformed ether.
