“…In human cases " salyrgan " and " mercupurin " have caused most of the deaths (Ben-Asher, 1945;Sundaram, 1934;Brown et al, 1942;Barker et al, 1942), but deaths are also reported following " esidrone" (Volini et al, 1945), " mersalyl " (Evans and Perry, 1943), and neptal (Greenwald and Jacobson, 1937). Animal experiments also demonstrate variation in toxicity, esidrone and mercupurin being singled out for especially unfavourable mention by Pines et al (1944).…”
