Note 978 — BOOK XXXIII. THE NATURAL HISTORY OF METALS.647

“Eye dilating.” Belladonna, a preparation from the Atropa belladonna, is now used in medicine for this purpose. A similar effect is attributed in B. xxv. c. 92, to the plant Anagallis. In reality, the application of prepared antimony would contract the eyelids, and so appear to enlarge the eyes. This property is peculiar, Ajasson remarks, to sulphuret of antimony, and sulphuret of antimony and silver.
