seemed to dream, but outwalked the Indian guides for two hours 

 till daylight. 



A dwarf bush of the mountains of Africa and a bulbous root 

 of Nebraska are alleged to possess similar properties. 



The hydery — quill — rhay (Indian tobacco) is used in British 

 Columbia and Alaska for the same effect as opium. 



Sleepy grass (Stipa inebrians and S. Siberica) of Texas and 

 New Mexico causes profound sleep or stupor for one or two days. 

 In horse causes diaphoresis and diuresis. 



Tutu (coriaria rustifolia) of New Zealand has poisonous seeds, 

 acting even fatally on fatigued cattle and sheep, but not on horse, 

 goat or pig. The narcosis lasts but a few hours. 



Treatment. Opium and some other alkaloids find an antidote 

 in potassium permanganate, to be supplemented by diffusible stimu- 

 lants. All may be counteracted by eliminants (vegetable emetics, 

 laxatives and diuretics), seconded by abundance of water and 

 other diluents. When the agent is acrid or irritant demulcents 

 (boiled flaxseed, raw eggs, milk, slippery elm, albumen, mallow, 

 gums, etc. ) should be used freely, and fomentations and poultices 

 applied over the abdomen and loins.

Definition. Tetany is the name given to a limited contraction 

 of a group of muscles usually in the extremities occurring 

 paroxysmally with intervals, during which it may usually be 

 roused into activity by compression of the nerve or artery pro- 

 ceeding to the muscles in question. 



The disease has not been accorded a place in systematic works 

 on veterinary medicine, though cases have been recorded which 

 are supposed to have been of this nature, and in cases occurring
