POISONS. 179 



Treatment: Dilute sulphuric acid (a 10 per cent 

 solution of the official dilute acid), commonly 

 called "oil of vitriol," in one dram doses, given 

 in a pint of water, forms insoluble lead sulphate. 



Epsom or Glauber 's salts in one ounce doses 

 dissolved in a pint of water, or a teaspoonful of 

 sulphur mixed with molasses and smeared on the 

 tongue may be given. A dram of potassium per- 

 manganate dissolved in a pint of cold water is 

 always good treatment, and may be administered 

 when the exact cause of the poisoning is not 

 known. 



Small doses of morphin, atropin, or glonoin may 

 be given hypodermically, or chloral hydrate may 

 be given per rectum. 



Treatment in acute cases of lead poisoning is 

 not very successful, as the animals are usually 

 too badly affected to even drench. 



Postmortem appearances: Only slight changes 

 are noticeable; this is especially true of the apo- 

 plectic form where the animals are found dying 

 in convulsions. 



2. Chronic Lead Poisoning. 



This is sometimes seen where lead mines are 

 found, or in the vicinity of smelters where the 

 fumes are blown on the grass. 



Symptoms: Gradual emaciation, colic, bluish 

 color around the gums followed by death from 

 general weakness. 



One must be guided largely by the history of 

 the case, and this is comparatively easy when one 

 is familiar with the country. Old or working
