Excerpt: ... by repeating as Mulder does not direct, as Mulder does not believe, and by observing that Liebig has purposely here told an untruth, simply with the view of complicating the protein question. My original memoir, in which I speak of about 140 F., was actually read by him at the time of its publication; and now he endeavours to make it appear as if I had applied the ordinary temperature. IV. Of Legumin. I feel it necessary here to correct an error which I have committed in mentioning the experiment of Rochleder upon legumin. (The Chemistry of Veget. and Anim. Physiology, p. 297.) I had overlooked the fact (Annalen, vol. xlv., p. 160), that Rochleder dissolved his legumin in a strong potash-ley without the aid of heat; this was lately called to my remembrance on the occasion of Van Laer's experiments upon legumin. I, therefore, correct this error at once. Rochleder treated legumin with potash at the ordinary temperature; this I had misunderstood in his paper. But does this prove that / have not formerly applied a heat of about 140 F., when treating these substances? Does this falsify what I published in 1838, and what Liebig himself, in 1842, copied in several places? I must speak distinctly; have I applied no heat, because I overlooked in Rochleder's paper, that he applied only the ordinary temperature? If any involuntary mistake should cause such a conclusion, this would become a sad, a dangerous precedent. All Liebig's works thus-overflow with unparalleled mutilation of truth.
