Characteristics

Thallium is a rare metal discovered by Crookes in the residuum left from the distillation of Selenium and named Thallium (θαλλός, a green shoot) from the green it gives in the spectrum (H. W., xxxiii. 242). It has been experimented with by Lamy and Marme. Some symptoms of Thal. sul., which is an energetic poison, are included (and distinguished) in the Schema. The symptoms observed on animals were from the sulphate, with which Lamy experimented (H. W., xxxiv. 82). Combermale, of Lille, used Thal. with success in the night-sweats of phthisis, but this treatment had the effect of causing profuse falling of the hair, so serious as to contraindicate its use. Huchard had patients become quite bald in several days. Hansen says Thal. relieves the violent pains of tabes dorsalis.

Relations

Thal. belongs to the Lead group of metals, and approaches Plumb. closest in its symptoms. Compare: Baldness, jabor., Pilo., Petr. Baldness and phthisis, Pho.
