104 VETEEINARY TOXICOLOGY 



symptoms of acute enteritis set in, and the animal died in 

 violent abdominal pain. 



A bull terrier* after eating a mouthful of carbolised 

 bran, nine hours later displayed muscular twitchings, fol- 

 lowed by paralysis of the hind quarters ; abdominal disten- 

 sion ; dif&cult respiration ; the mucous membranes of the 

 mouth white and hardened. The symptoms lasted about 

 four hours, with occasional attacks of convulsions, and 

 recovery took place within twenty -four hours. The 

 amount of carbolic acid taken could not have exceeded 

 1'25 grains. 



A dog ^ having a crushed foot was dressed with ointment 

 and given four pills which contained creosote, after which 

 there was vomiting and diarrhoea, the ejecta smelling of 

 creosote; a weak and quick pulse; temperature 105° P. 

 Under treatment with stimulants, alternating with sodium 

 sulphate, there was gradual recovery. 



An interesting case® refers to the poisoning of cats by 

 carbolic disinfectant powder. In this case clonic and tonic 

 spasms, dilatation of the pupils, salivation, irregular and 

 feeble heart action, well illustrate the nervous symptoms of 

 carbolic acid poisoning. 



Hobday made a series of very careful observations on 

 the dangers of disinfectants, and investigated creolin,^ 

 chinosol,' and izal.® Chinosol is a derivative of the base 

 quinoline, but for convenience may be included here. 

 Hobday's results confirmed the toxicity (in spite of ex- 

 aggerated statements to the contrary) of these agents when 

 improperly employed. With delicate breeds of dogs and 

 cats Hobday advises that the total application of creolin 

 should not exceed 10 to 15 minims. In poisoning by it he 

 indicates subnormal temperature, paralysis of hind legs, 

 followed by complete paralysis, prostration, and clonic 

 spasms, well marked in limbs, jaws, and eyelids. Death 

 from collapse follows coma. 



Cats are more susceptible than dogs to chinosol, and it 

 should not be injected in doses exceeding J^ grain and 

 J grain per pound body weight of the cat or dog respectively.
