According to Friedberger and Fröhner (_vide_ Pammel) animals affected by potato tops show symptoms resembling those of foot-and-mouth disease. According to Pott the _berries_ cause colic and foul smelling diarrhœa in _cattle_. A German veterinary surgeon after feeding the green plant observed symptoms of delirium, paralysis, and flatulence. In other cases trembling and uncertain gait, with paralysis of the spinal cord, have been observed in _cows_. In poisoning by _tubers_ there is depression, loss of appetite, cessation of lactation, gritting of teeth, profound prostration, with a remarkable somnolence, but no dilatation of the pupils. The animals remain recumbent, with closed eyes, and refuse to get up. Respiration is somewhat retarded, and the pulse is small and accelerated. There are digestive disturbances, tympanitis, diarrhœa succeeds constipation, and there is vomiting (where possible). The poisoning is usually fatal. Where a large quantity of sprouted Potatoes has been fed the prostration becomes paraplegia, with loss of sensibility, stupefaction, and death. Where there is prolonged ingestion of a large quantity of unsprouted tubers there is prostration, intestinal irritation, rapid emaciation and death in marasmus after an illness of from one to three weeks (Cornevin). Pott states that potatoes diseased with wet rot, when fed raw, cause digestive troubles, bloating, diarrhœa, abortion, and decrease in milk yield, with fatal results in some cases. Potatoes diseased with dry rot cause constipation in sucking pigs, and a “fishy” butter from cow’s milk. Lander notices two cases of poisoning of _horses_ by tubers. In the first case the symptoms were a small and weak pulse, normal temperature and loss of coordination in movements; complete loss of appetite, excessive thirst, but inability to drink; mydriasis, stertorous breathing, suspension of peristalsis, and slight tremors over the crural muscles. In the second case there was a rapid and feeble pulse, temperature 103° F., intense congestion of the mucous membranes, and very fœtid diarrhœa, terminating fatally. In poisoning of _horses_ after receiving large quantities of raw Potatoes, Pott records boil-like swellings on the skin, loss of hair, diarrhœa, inflammation of the stomach and intestines, skin irritation, and swollen fetlocks and hocks. In reference to the horses mentioned above (p. 55) it is stated that an affected animal seems dull, and dies within twelve hours after being first observed, without evincing any sign of pain. The first symptoms in ten cases were weakness and loss of power over the limbs.
