One drachm of croton seeds given to a horse, without water proved fatal in 24 hours (Morton); 2 drachms followed by all the water the horse would drink produced most violent catharsis followed by recovery (Hughes). Twenty to thirty drops of croton oil proved fatal; 8 drops in the jugular vein caused death (Hertwig). It is much less fatal to cattle. Dogs and pigs vomit it so readily that they usually survive with profuse catharsis. The _symptoms_ are profuse watery diarrhœa with tenesmus, congested mucosæ, rapidly increasing weakness and small pulse, becoming imperceptible. The _lesions_ are violent congestion of the mucosa of stomach and intestines, concentrated very largely on the cæcum and colon. _Treatment_ consists in abundance of mucilaginous liquids, which the animal readily drinks, and washing out the stomach with the stomach tube or pump. Opiates may be demanded to calm the pain. POISONING BY EUPHORBIA. In Europe _euphorbia lathyris_ has been found to produce in animals, colic, constipation, tympany, followed by bloody diarrhœa, stupor and hæmaturia. In America the euphorbia corollata (large flowering spurge) and euphorbia ipecacuanhæ (ipecacuanha spurge) though less potent have a similar action. _Treatment_ consists in favoring elimination by emesis, and abundant mucilaginous and demulcent agents. POISONING BY BOX LEAVES. The leaves of buxus sempervirens, used as a border in gardens, contains an acrid principle. After eating 1½ lb. a horse had colic, tympany and enteritis. After death the lesions of gastro-enteritis were found (Weiss). _Treatment_ would be by stomach pump, laxatives, demulcents and anodynes. POISONING BY DAFFODILS. (NARCISSUS POETICUS, AND NARCISSUS PSEUDO NARCISSUS). These common denizens of gardens produce intense gastro-enteritis, profuse diarrhœa, spasms, stupor and weakness. _Treatment_ will not differ materially from that advised in box poisoning. POISONING BY RANUNCULUS. The _ranunculus acris_ (tall crowfoot), _repens_ (creeping crowfoot), _sceleratus_ (cursed crowfoot), and _bulbosus_ (butter cup), are all more or less acrid and liable to produce gastro-enteritis when taken in quantity. They are usually avoided by animals but will sometimes be taken by accident with other vegetation. Sheep are said to eat ranunculus bulbosus with impunity (Daubenton). Both cattle and sheep suffered from the other species (Delafond, Lipp, Brugnone, Delplanque). There were salivation, colic, emesis in vomiting animals, diarrhœa, vertigo, spasms, grinding of the teeth, arched back and staring coat. _Treatment_ would be emesis or the stomach pump when available, mucilaginous drinks and enemata. Johnson (Medical Botany of North America) had a herd of cows abort for years on a field thickly set with ranunculus acris, but which ceased to abort when removed to a field from which this weed was absent.
