According to . Friedberger and Frohner (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 diarrhoea 
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 re- 
cumbent, with closed eyes, and refuse to get up. Eespiration is somewhat 
retarded, and the pulse is small and accelerated. There are digestive 
disturbances, tympanitis, diarrhoea succeeds constipation, and there 
is vomiting (where possible). The poisoning is usually fatal. 
Where a large quantity of sprouted Potatoes has been fed the pros- 
tration becomes paraplegia, with loss of sensibility, stupefaction, and 
death. Where there is prolonged ingestion of a large quantity of un- 
sprouted tubers there is prostration, intestinal irritation, rapid emacia- 
tion 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, diarrhoea, 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 tempera- 
ture and loss of co-ordination 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 foetid 
diarrhoea, terminating fatally. 
In poisoning of horses after receiving large quantities of raw Potatoes, 
Pott records boil-like swellings on the skin, loss of hair, diarrhoea, in- 
flammation 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
