Occupational mercury tremor in fur factory worker (2)
Occupational mercury tremor in a 52-year-old woman who worked collecting the rabbit fur that had been removed from the skins by machinery previously treated with preparations of mercury. Case of English surgeon John Fawcett (1866-1944).
(C) Strong voluntary movement (pressure) of hand not on tambour. Six tremors per second. Amplitude was about twelve times as great as at rest. The excursions very much more regular than any of the others.
(D) Immediate after-effect of C. Five tremors per second. Very regular in amplitude, becoming very small indeed after a short time.
