In the spring, and late in the fall, catarrhal affections are quite
common, occurring frequently in a epizooetic form. Coryza, or nasal
catarrh,--commonly called a cold in the head,--is not very common among
cows. As its name implies, it is a local disease, confined to the lining
membrane of the nose; and, consequently, the general system is not
usually disturbed.
_Symptoms._--The animal will be observed to sneeze; the Schneiderian
membrane (membrane of the nose) is heightened in color; cough sometimes
accompanies; there is also a muco-purulent discharge from the nose.
Neglect to attend to these early symptoms frequently occasions disease
of a more serious nature; in fact, coryza may be regarded as the
forerunner of all epizooetic pulmonary disorders.

_Treatment._--The animal should be kept on a low diet for a few days;
the nostrils occasionally steamed, and one of the following powders
given night and morning, which, in most cases, will be all the medicine
required: nitrate of potassa, one ounce; digitalis leaves pulverized and
tartrate of antimony, of each one drachm; sulphate of copper, two
drachms; mix, and divide into eight powders. Should the disease prove
obstinate, give for two or three days two ounces of Epsom-salts at a
dose, dissolved in water, three times a day.
