392 THE DOG IN DISEASE. 



injected in solution in only a small quantity of water, well 

 up into the bowel, and prevented from returning. The 

 dose may be repeated, if necessary, till at least a drachm has 

 been taken. Hypodermic injections of chloral are valuable. 



The best antidote for arsenic is the hydrated oxide of 

 iron, which can be quickly prepared by adding baking 

 soda or washing soda to diluted tincture of iron so long as 

 there is any effervescence — i. e., till the neutral point is 

 reached. This may be given freely, say a tablespoonful 

 Qvery ten minutes. 



When an animal's strength is failing, aromatic spirits 

 of ammonia, carbonate of ammonium, or alcohol in re- 

 peated doses, are demanded. 



In poisoning by mercury, little can be done to allay 

 the symptoms, which are those of gastritis and enteritis, 

 with corrosion of the mouth. The indications are to 

 maintain the strength of the patient, as in other cases. If 

 he survives the acute attack the mouth should be treated 

 with astringent washes. Of course, the stomach should be 

 protected mechanically, as in other cases. 



Carbolic-acid poisoning is marked by twitchings, possi- 

 bly convulsions, or great prostration. The animal should 

 be kept warm, and stimulants given. The danger of poi- 

 soning from lotions, ointments, etc., containing carbolic 

 acid is not to be forgotten ; but as recovery is more fre- 

 quent than in poisoning by many other agents, treatment 

 is hopeful. 



Stings. — This subject may be briefly alluded to under 

 the head of " Poisoning," as the danger and pain of stings 

 arise in great part from the poison introduced into the 

 wound.
