Note 103 — SECRET POISON.
William Johnston translation
Heberden in the Neue Hamburg. Mag. xvii. p. 219. I am convinced that many of the accounts we have of the extraordinary effects of poison are fabricated, like those mentioned in Frid. Hoffmanni Dissert. de Læsionibus externis, abortivis Venenis ac Philtris. Francof. 1729, et recusa Lips. 1755. That author, however, denies some which are true. It is, for example, certain that camphor and rue do not produce the effects ascribed to them by Dioscorides, Paulus Ægineta, and others; but there are without doubt other substances which will produce these effects.
