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.

COW-POX.

Two varieties of sore teats occur in the cow, in the form of pustular
eruptions. They first appear as small vesicles containing a purulent
matter, and subsequently assume a scabby appearance, or small ulcers
remain, which often prove troublesome to heal. This latter is the
cow-pox, from which Jenner derived the vaccine matter.

_Treatment._--Foment the teats well with warm water and Castile-soap;
after which, wipe the bag dry, and dress with citrine ointment. The
preparations of iodine have also been recommended, and they are very
serviceable.

DIARRHOEA.

Cattle are frequently subject to this disease, particularly in the
spring of the year when the grass is young and soft. Occasionally it
assumes a very obstinate form in consequence of the imperfect secretion
of gastric juice; the _faeces_ are thin, watery, and fetid, followed by
very great prostration of the animal.

The symptoms of diarrhoea are too well known to require any detailed
description.

_Treatment._--If in a mild form, the diet should be low; give two ounces
of Epsom-salts, twice a day. In a more obstinate form, give t
