Note 20 — Chapter XV
I. Stone Sanpietro translation
The professors, A. Benedicenti and G. B. De Toni, of the Camerino University have published the result of their studies upon the roots and some juice extracted from the broial which I sent them for the purpose in 1902. I think, however, that the conclusions of these two scientists would have been in favour of a greater and quicker effect of this poison if, in spite of all my care, the samples had not suffered from the change of climate and, very likely, been exposed to dampness.
