92 GENERAL THERAPEUTICS FOR VETERINARIANS 



(d) Excitants to the vasomotor centre: caffeine, theobromine, 



theocine and digitalis. 



(e) Depressor to the vasomotor centre: amyl nitrite. 



(f) Excitants to the vagus centre: digitalis and strophanthus. 



(g) Excitants to the centre of vomition: apomorphine and 



emetine. 

 3. The specifics for the cranial nerves are: 



(a) Olfactory: strychnine. 



(b) Optic: strychnine, quinine, santonin, aspidium and amyl 



nitrite. 



(c) Oculomotor: the mydriatics — ^atropine and hyoscine (scopo- 



lamine) ; the myotics — eserine, pilocarpine and arecoline. 



(d) Trochlear (and abducens) : santonin. 



(e) Trigeminus: strychnine, aconitine and cocaine. 



(f) Facial: strychnine. 



(g) Auditory: quinine, salicylic acid and cannabis indica. 

 (h) Glossopharyngeal: apomorphine and atropine. 



(i) Vagus: atropine, hyoscine (scopolamine), the digitalis 



group, strychnine and veratrine. 

 (k) Hypoglossal: strychnine. 



In addition, atropine, ergot, cocaine and amyl nitrite are 

 specific for the sympathetic, and atropine and morphine for the 

 splanchnic nerves. 



n. Spinalics are divided, according to their action, into: 



(a) Tetanies: strychnine and cornutine (lumbar cord). 



(b) Sedatives: morphine, potassium bromide and chloral 



hydrate. 



in. Peripherics. These are classified according to the func- 

 tions of the peripheral nerves as follows: 



(a) Motor excitants: camphor and eserine. 



(b) Motor sedatives: curare and conine. 



(c) Sensory excitants: veratrine and cutaneous irritants. 



(d) Sensory sedatives or local anaesthetics: cocaine, adrenalin, 



novocaine, ansesthesin, eucaine B, tropacocaine, alypin,
