sesthesia, convulsions and paralysis, weak, slow, irregular respira- 

 tion, feeble, rapid pulse, paralysis of the sphincters, stupor and 

 death. Death occurs mainly from asphyxia and in part from car- 

 diac failure. — A few drops of the urine from the poisoned animal 

 placed in the eye of a healthy animal will dilate the pupil. 



Antidotes and Antagonists. — In poisoning, Tannic Acid 

 should be used, evacuate the stomach. Opium is the physiologi- 

 cal antagonist for its effects on the cerebrum, pupil, heart, respira-

Physostigmine, Aconite, Pilocarpine and Quinine are each 

 antagonistic to some of its effects ; muscarine to most of them. 



Medicinal Uses of Belladonna and Atropine. — Belladonna is 

 indicated anywhere that an antispasmodic and anodyne is needed.

 heaves, combined with gelsemium and lobelia, followed by Fowl-

In first stage of respiratory diseases, belladonna alone, or 

 combined with aconite or other febrifuges and expectorants ; in 

 cough especially spasmodic or when due to irritation of the

 small doses are given in constipation of the bowels, combined with 

 nux vomica ; small doses with purgatives are said to aid their

In tetanus give 1 to 2 drs. of the extract 2 or 3 times daily ; 

 in paralysis of the throat of tetanus the fluid extract combined 

 with soap liniment or used alone externally ; in cerebro-spinal 

 meningitis, belladonna and ergot alternated with aconite is ra-
