According to Christison’s researches, 0·2 grm. (about 1⁄3 grain) is fatal to swine; ·03 grm. (1⁄2 grain) to bears, if injected into the pleura. 1 to 3 grains (·0648 to ·1944 grm.) is given to horses in cases of paralysis, although 3 grains cannot but be considered a dangerous dose, unless smaller doses have been previously administered without effect; 10 grains would probably kill a horse, and 15 grains (·972 grm.) have certainly done so.
