CARBOLIC ACID AND DISINFECTANT PREPARATIONS. Ill 
Carbolic acid prevents oxidation, and coagulates albumi¬ 
nous matters, and is hence a most valuable antiseptic. A 
few drops mixed with fresh urine prevents its undergoing 
any change for several months; meat washed with a weak 
solution keeps unchanged for weeks; whilst skins, solutions 
of gelatine, starch, size, and other such substances prone to 
decay, are readily preserved when moistened with it. A 
minute quantity mixed with recent manure prevents or 
arrests putrefaction, obviates all smell, and, by retaining and 
permanently fixing the ammonia and other volatile matters, 
it greatly enhances the value of the manure so treated. For 
most of these purposes M‘Dougairs disinfecting powder and 
fluid are now largely used, and especially for the healthful 
purification of stables, cow-houses, piggeries, and poultry- 
pens. In some of the extensive omnibus and carrying estab¬ 
lishments of London, Manchester, and other large towns, it 
is employed daily at an annual cost of 5s. for each horse. It 
is also employed for the cleaning and purifying of railway 
horse-boxes and cattle-trucks; and for these and similar 
uses its cheapness and efficacy recommend its more general 
adoption. 
As an internal remedy, pure carbolic acid, in the form 
either of the clear fluid or the crystallized solid, is preferable. 
For horses and cattle the dose varies from ii\xv to njxl, 
for sheep from B|v to rrpviij, and for dogs npj to utij. 
Where the crystallized form is used, grains instead of minims 
will be given. It is conveniently administered either in a 
bolus with linseed meal or dissolved in a little diluted spirit. 
Where there is extreme irritability of the bowels, carbolic 
acid may be conjoined with half a dose of laudanum, or a 
little chalk, carbonate of soda, or other antacid. As a dress¬ 
ing for wounds, a solution may be made with one part of the 
acid and from fifty to eighty parts of water; a few drops may 
be added to the sugar of lead or other healing lotion, or 
mixed with oxide of zinc or such other astringent ointment. 
Mr. M tf Dougairs fluid, foot-rot ointment, aud other prepara¬ 
tions, are well adapted for the purposes for which they are 
intended .—North British Agriculturist.
