It has been a very common observation in regard to the dose of turpentine, that the patient suffers more cephalic distress when it is given in small quantity, than in a large dose. The writer of this has been obliged to desist from the exhibition of oil turpentine, in doses of [Symbol: dram]ij twice a day, in consequence of a vertigo so considerable, as to alarm and distress his patient very much. Perhaps there might have been in this case some peculiar liability to nervous excitation, which in another patient would not have been worthy of much notice. Dr. KNOX'S opinion is of great weight. The celebrated remedy of CHABERT, Dr. KNOX thinks, owes its efficacy to the ol. terebinth. combined with it. Dr. FRANK, whose name stands at the head of this article, was informed by the celebrated helminthologist, Dr. BREMSER, at Vienna, in 1814, that he had for ten years preferred the use of CHABERT'S remedy, and with invariable success. CHABERT was a veterinary surgeon of Alfort, who used the animal oil of Dippel in many diseases of animals, as well as those of men. This oil he often gave for the purpose of removing taenia in his animals. He often combined it with spt. terebinth. and gave equal parts of these substances, in doses of [Symbol: dram]i.[20] The London Medical Repository states, that CHABERT'S remedy is prepared from Ol. Corn. Cerv. Foetid. 1 part. Ol. Terebinth, 3 parts. These are well mixed, and left at rest four days; they are then distilled in a sand bath, till three-fourths of the liquor has passed over. It must be kept tightly stopped, out of the light.[21] The great objection to CHABERT'S remedy is its disgusting flavour; which is the more obnoxious, because the remedy must be continued for a length of time. Dr. FRANK cured two persons affected with taenia solium, after considerable perseverance with it: he cured two other persons with a preparation as follows: Ol. Terebinth. [Symbol: ounce]ss Aether Sulphuric. [Symbol: dram]ij Pulv. G. Arab. [Symbol: ounce]ss Aq. Flor. Chamam. distil. [Symbol: ounce]xvj _m._ Two spoonfuls morning and evening. Four of these mixtures were sufficient to cure the patients, who remained well two years afterwards. A fifth patient, unable to take the last named medicines, was cured by the boluses subjoined: Sem. Santonic. pulv. [Symbol: ounce]ss Pulv. Jalap. Ferri Sulphat. aa [Symbol: dram]i Ol. Corn. Cervi, gtt. viij. Syrup. q.s. Make 20 boluses. One to be taken morning and evening. These 20 boluses being repeated three times, the patient found himself perfectly well. In the above 5 cases, the taenia was discharged in fragments.
