244 VETEEINAEY TOXICOLOGY 



co-ordination in movements ; complete loss of appetite, 

 excessive thirst, but inability to drink ; mydriasis, stertorous 

 breathing, suspension of peristalsis, and slight muscular 

 tremors over the crural muscles. 



In cases of horse poisoning encountered by G. T. Willows,* 

 a very rapid and feeble pulse, temperature 103° F., intense 

 congestion of the mucous membranes, and very foetid diar- 

 rhoea, were observed, the cases terminating fatally. With 

 pigs fed on steamed potatoes which were budding, and which 

 had the buds on, Schneider t observed after a few days loss of 

 appetite, dulness, exhaustion, imperceptible pulse, watery 

 diarrhoea, low temperature, and comatose condition. Accord- 

 ing to Cornevin, when animals are fed with raw and entire 

 potatoes there is depression, loss of appetite, cessation of 

 lactation, gritting of the teeth, and profound prostration, 

 with a remarkable somnolence, but no dilatation of the pupils. 

 After a period of constipation there succeeds diarrhoea and, 

 when possible, vomition. In the less acute forms the pros- 

 tration is the dominant characteristic, to which is added 

 the intestinal irritation, with rapid loss of flesh. 



Post-Mbrtem Appearanees. — The post-mortem lesions 

 are those of acute or chronic enteritis according to the 

 course of the poisoning. The other viscera are not abnormal, 

 but there is congestion of the cerebral membranes. 



Treatment. — In the potato poisoning of horses Saunders 

 (loc. cit.) gave 1 grain of strychnine subcutaneously, and 

 rectal injections of warm water. Next day there was 

 purgation, and J grain of arecoline bromide speedily caused 

 profuse salivation and sweating. Offensive black faeces 

 were expelled. Eventually the horses recovered. 



Some of the pigs treated by Schneider recovered after 

 tannin and linseed tea. 



Bitter-Sweet. — Solanum dulcamara (Fig. 35), or bitter- 

 sweet : Stem shrubby at the base, with climbing or straggling 

 branches, often many feet in length, but dying far back in 

 winter. Leaves stalked, ovate or ovate-lanceolate, 2 or 

 3 inches long, usually broadly cordate at the base and entire,
