In other cases very good results have been obtained from giving permanganate of potash in the form of a drench: 5 to 10 grains for an adult sheep or pig, 15 to 20 grains for a horse, and 30 to 50 grains for an ox, dissolved in a pint or two pints of water.

* Delphinium geyeri.—The Wyoming larkspur is well known throughout Wyoming, Colorado, and Nebraska under the name of poison weed. It is reported to be the most troublesome plant to stock in Wyoming, the dark-green tufts of foliage being especially tempting in spring when the prairies are otherwise dry and barren.
