To J. S. Burdon Sanderson 26 June [1873]
Summary
Would welcome JSBS visit to discuss Drosera. Nitrogenous fluids can act as ferments only if they act merely by exciting molecular movement in adjoining molecules.
Glass and cotton excite movement and cause cell contents to change visibly. Huxley coming to see this phenomenon.
Studied effect of poisons 12 or 15 years ago to see whether the action was similar to that on nervous tissue.

From Anton Dohrn 7 June 1873
Summary
News of Naples Zoological Station developments.
His remarks on physiology in the Academy were aimed at Prof. Ludwig and his school.
The usual "exact" methods in experimental physiology want only a little pushing to put an end to superstition.
Recounts how he had worked out the explanation of Rhizocephala morphology via the Anelasma – an example of both the power of inheritance and the power of genealogical investigation. R. Kossman’s work has now confirmed AD’s explanation.
