Those belonging to the second class must receive the same strengthening and tonic ration in the morning; and, twice every day, one of the following anti-contagious preparations: either a solution of _chlorate of potash_ or of _permanganate of potash_; two drachms of either of these salts dissolved in eight ounces of warm water, mixed afterwards with a gallon of an infusion of sage or hyssop, just at the time when the drink is given to them.
Or you may employ, for the same purpose, a solution of arseniate of soda--two grains dissolved in four ounces of water, and mixed with their drink in the same way. You need hardly be told that these doses must be reduced one half, when you have to treat a calf or a heifer, and that the same diminution will hold good, in their cases, for all other medicaments. _The use of these anti-contagious drinks is of the highest importance; I recommend you earnestly to study their effects, and to continue them even after the distemper shall have broken out._
These drinks having no disagreeable taste, the cattle take to them in general; should the contrary be the case, give them in a bottle as all men who are cattle owners know how to do.
If the health of any of these animals among which the outbreak of the typhus is apprehended should seem below the standard, you must apply a purgative to those whose bowels do not operate well, and even have recourse to bleeding in exceptional cases.
During the absence of those cattle which are undergoing the preventive treatment, let the hygienic conditions of their stalls and sheds be looked to; for no circumstance must be overlooked or neglected if we hope to withstand the propagation of so formidable a malady. Be careful to take out the litter every day, to wash the floor and cleanse it of the droppings, to ventilate the place thoroughly, to fumigate it with burnt sulphur or aromatic plants, such as juniper berries, sage, rosemary, salted with nitrate of potash and arsenic acid; in order to promote the combustion and give effect to its disinfectious properties. At night, camphor or tar, or naphthaline, or creosote, or even iodine, may be left in the stable to diffuse their vapours; all these measures are very effectual in modifying the air.
