MATERIA MEDICA AND THERAPEUTICS. 1 15 



abortion in pregnant animals. Large doses of the irritating prep- 

 arations cause gastro-enteritis. 



Antidotes. — Best is albumen, the white of one egg to 4 grs 

 of corrosive sublimate, emesis for dogs, stomach pump for horse ; 

 cathartic; wheat flour, milk, atropine, etc. 



Incompatibles.— Incompatible with nearly everything.; calo- 

 mel with hydrochloric acid or chloride of soda or other chlorides 

 form corrosive sublimate; corrosive sublimate and pot. iod. form 

 red iod. of mercury, etc. Best to prescribe them alone. 



ARGENTUM— SILVER. 



There is an oxide, cyanide and iodide, but the nitrate is 

 most important. 



ARGBNTI NITRAS— Nitrate of Silver.— A heavy color- 

 less salt wholly soluble in water; always use distilled water in 

 making a solution, and protect the bottle from light and heat. 



Dose. — Horses and cattle, 5 to 10 grs. ; sheep, 1 to 2 grs. ; 

 pigs, yi to 1 gr. ; dogs, fo to 1 gr. average dose for dog J4 ° r 

 i of a gr. 



ARGBNTI NITRAS FUSUS— Fused Nitrate of Silver- 

 Lunar Caustic. — Used only for topical applications, occurs in little 

 sticks about y 2 the size of a lead-pencil. 



Antagonists and Incompatibles. — All chlorides form insoluble 

 chlorides of silver, mineral acids, alkalies and their carbonates, 

 other astringents and lime-water; in case of poisoning by any of 

 the silver preparations use common salt to form the insoluble 

 chloride of silver. 



Synergist. — All waste producers, as mercury, iodides, etc. 

 favor its actions. 



Physiological Actions. — Silver nitrate combines with the 

 albumen of the tissues, and is a limited caustic ; causes superficial 

 inflammation and stains the parts black ; small doses increase se- 

 cretion and stimulate the heart. It promotes nutrition, and is said 

 to be a nerve tonic. 



Toxicology. — Its continued administration causes general 

 waste, gastro-intestinal catarrh, fluidity of blood, slate colored 

 lines about the gums, and similar discoloration of skin and mu- 

 cous membrane, followed by nervous disorder, paralysis, con- 

 vulsions and death.
