Uses Internal. — Alum is a prompt, safe and non-depressing emetic 

 for dogs. It is suitable in poisoning, or when the secretions are excessive 

 in laryngitis or bronchitis. Teaspoonful doses should be given in solu- 

 tion in syrup every 15 minutes in these latter diseases, until vomiting 

 occurs. Alum in the proportion of 1 dram to the pint of warm water 

 makes an excellent enema for emptying the bowels. Aluminum hydroxide 

 is an antacid and astringent. It combines with acid in the stomach (ant- 

 acid) and goes into a soluble form when it acts as an astringent in the 

 bowels. It is, therefore, more applicable for internal use in the treatment 

 of diarrhea and dysentery. Other astringents, such as tannic acid in 

 some form, lead acetate, or copper sulphate, are, however, usually more 

 valuable in diarrheal disorders. 



Alum is recommended for the cure of acute laminitis given inter- 

 nally (3ii-vi. in ball every 2 hours), but there is no basis for the produc- 

 tion of remote contraction of vessels in the foot in the physiological action 

 of the drug. Its use in this manner is purely empirical. 



Cerium. 



(Cerium is not employed medicinally.) . 

 Cebii Oxalas. Cerium Oxalate. Ccz (Cj04)34-9 H^O. (U. S. & B. P.) 



Synonym. — Cerous oxalate, E.; oxalate de cerium, cerium oxalicum, Fr. ; oxal- 

 saures ceroxydul, ceroxalat, G. 



Derivation. — Precipitate a solution of ammonium oxalate with a soluble salt 

 of cerium. 



Properties. — A fine white, or slightly pink powder, without odor or taste, and 

 permanent in the air; insoluble in water, alcohol or ether. 



Dose. — D., 3ss-ii, (2-4). 



Action and Uses. — The physiological details concerning the action of cerium 

 are unknown. It is useful in relieving vomiting by mechanically protecting the 

 gastric mucous membrane, and is often combined with bismuth salts. Cerium is 

 absorbed with difficulty from the digestive tract and, as 1% ounces by the mouth 

 do not poison dogs, the dose should be % to 1 dram (Baehr & Wessler, 1909). 

 Given intravenously, it produces poisoning resembling that of bismuth.
