CERIUM 



The only salt of cerium used in medicine is the insoluble oxalate. 



CERII OXALAS — CERIUM OXALATE 



Properties. Cerium oxalate occurs as a white or slightly pink- 

 ish, odorless powder, insoluble in water and alcohol. 



Doses. Dog gr. x — xxx; 0.6 — 2. Cat gr. v — xv; .33 — 1. 



Actiou and Uses. Cerium oxalate resembles the insoluble bis- 

 muth salts in action and uses. Like the bismuth salts it is protect- 

 ant and may be of considerable service to check vomiting due to irri- 

 tation of the stomach, but does not check vomiting of central origin. 

 Baehr and Wessler found it non toxic in 50 gi-am doses in dogs and 

 believed the ordinary doses of a few grains to be too small. They 

 recommend 30 to 60 grains as the human dose. 



It is used to check nausea and vomiting due to irritation of the 

 stomach and is frequently combined with bismuth for this purpose.

PLUMBUM — LEAD 



Lead salts differ from the other heavy metals in being astringent 

 instead of corrosive. They may produce sufficient corrosion to be 

 absorbed but not sufficient for acute poisoning from systemic ef- 

 fects, no matter how administered or in what amounts. The small 

 amounts absorbed are not sufficient for acute poisoning but since 

 lead is excreted slowly, it fulfills the conditions necessary for cumula- 

 tive action if the dosing or exposure is prolonged. 



Single moderate doses of the acetate or other salts do not exert 

 any effect beyond the digestive tract where they are astringent. 

 Large doses of lead salts act as irritant poisons and produce violent
