Dr. Ramskill has recorded two cases of epilepsy preceded by a "gastric aura" - i.e., "a sense of faintness, and of something turning upside down at the epigastrium" - which were benefited by the oxalate of cerium, when belladonna and bromides had failed to relieve. Cases of epilepsy without this aura were not benefited, and Dr. Ramskill suggests that in the gastric cases there was a primary failure of action in the splanchnic nerves, that the medicine acted as a sedative and conservator of their power, and that this influence being conveyed to the medulla lessened its excitability (Medical Times, i., 1862). The cerium salt has at least this advantage over nitrate of silver, that it will not darken the skin.
Cerii oxalas: dose, 1 to 5 gr. or more- according to Dr. Image, 10 gr. For an infant or child under two years, 1/4 to 1/2 gr.
[Preparation, U. S. P. - Cerii oxalas.]
Mr. H. Greenish asserts that commercial oxalate of cerium contains a large proportion of the oxalates of lanthanium and didy-mium, and that the pharmacopoeial test does not exclude their presence; this may possibly account for failure in some cases (Medical Record, 1877).
