| Powdered myrrh, | 2 ounces. |
| Proof spirit, | 1 pint. |
Set it aside in a close-covered vessel for two weeks, then strain through a fine sieve, and it is fit for use.
Oak Bark, (quercus alba.) A decoction of oak bark is a good astringent, and may be given internally, and also applied externally in falling of the womb or fundament.
Ointments. We have long since discontinued the use of ointments, from a conviction that they do not agree with the flesh of cattle. Marshmallows, or tincture of myrrh, will heal a wound much quicker than any greasy preparation. We have, however, often applied fresh marshmallow ointment to chapped teats, and chafed udder, with decided advantage. It is made as follows: Take of white wax, mutton tallow, and linseed oil, each a pound; marshmallow leaves, two ounces. First melt the wax and tallow, then add the oil, lastly a handful of mallows. Simmer over a slow fire until the leaves are crisp, then strain through a piece of flannel, and stir the mixture until cool.
Oleum Lini, (flaxseed oil.) This is a useful aperient and laxative in cattle practice, and may be given in all cases of constipation, provided, however, it is not accompanied with chronic indigestion: if such be the case, a diffusible stimulant, combined with a bitter tonic, (golden seal,) aided by an injection, will probably do more good, as they will arouse the digestive function. The above aperient may then be ventured on with safety. The dose for a cow is one pint.
Olive Oil. This is a useful aperient for sheep. The dose is from half a gill to a gill.
Opodeldoc. The different preparations of this article are used for strains and bruises, after the inflammatory action has somewhat subsided.
Liquid Opodeldoc.
| Soft soap, | 6 ounces. |
| New England rum, | 1 pint and a half. |
| Vinegar, | half a pint. |
| Oil of lavender, | 2 ounces |
The oil of lavender should first be dissolved in an equal quantity of alcohol, and then added to the mixture.
