Nitrate of Cerium. Nitrate of the Protoxide of Cerium. CeO,NO5.

Cerii Oxalas. Oxalate of Cerium. Oxalate of the Protoxide of Cerium. CeO,C2O3.

Med. Prop. and Action. The Salts of Cerium are regarded by Prof. Simpson,* of Edinburgh, who first introduced them as remedial agents, as posse-sedative and tonic properties, and as useful substitutes, the Nitrate especially, for Bismuth, Nitrate of Silver, and Hydrocyanic Acid.

Dose of the Cerium preparations, gr. iij. - gr. v., in the form of powder or pill, or the Nitrate may be given in solution.

791. Therapeutic Uses

In Chronic Intestinal Eruption, a peculiar and intractable form of disease for which Arsenic and Nitrate of Silver are generally prescribed, Dr. Simpson employed the Salts of Cerium with marked advantage. In Irritable Dyspepsia attended with Gastrodynia, Pyrosis, and Chronic Vomiting, its exhibition was attended with satisfactory results. In the Vomiting of Pregnancy it afforded prompt relief. Further testimony in favour of the Oxalate, especially in the latter condition, is adduced by Dr. C. Lee. It seems well worthy of further trials.

792. In Epilepsy, Chorea, and other allied Convulsive Diseases in which the Nitrate of Silver is generally employed, it deserves a trial; for, as Prof. Simpson remarks, it is certainly attended with this advantage, that at the same time that it acts as a tonic and sedative, its use may be persevered in without any fear of discoloration of the skin.
