Chronic lead-poisoning produces a bluish line along 

 the margins of the gums, an unsteady gait, swellings 

 around the articulations (with beat or tenderness), 

 impaired sensibility, difficult breathing, in some ani- 

 mals constipation, in others diarrhoea with colicky 

 pains. It is best treated with sodium iodide to satura- 

 tion. The antidotes for acute lead-poisoning are Ep- 

 som salt or Glauber salt; the stomach-pump if prac- 

 ticable; albuminous drenches and henbane or opium 

 to reheve irritability. 



Physiological Actiox. — Lead salts are astrin- 

 gent and styptic if given internally; externally, 

 astringent, mildly antiseptic, anodyne, and slightly 

 stimulate to absorption of deposits of inflammatory 

 products. 



Therapeutics. — In eczema, erythema and im- 

 petigo, combined with glycerin, carbolic acid, and 

 water. To bums, the carron oil with Goulard's ex- 

 tract or Goulard's extract and linseed oil. To sprains 

 and strains, also painful swellings, the liquor plumbi 

 et opii ; catarrhal discharges of muco-purulent charac- 

 ter; to wounds and abrasions. In internal hemor- 

 rhages, the acetate; the same with or without opium 

 in diarrhoea and dysentery. Should not be applied 

 to the eye, as it may leave a deposit which is difficult 

 to remove.
