Von Baer writes to me thus:--Et outre cela, je trouve que vous ecrivez encore des redactions. Vous avez ecrit sur l'ouvrage de M. Darwin une critique dont je n'ai trouve que des debris dans un journal allemand. J'ai oublie le nom terrible du journal anglais dans lequel se trouve votre recension. En tout cas aussi je ne peux pas trouver le journal ici. Comme je m'interesse beaucoup pour les idees de M. Darwin, sur lesquelles j'ai parle publiquement et sur lesquelles je ferai peut-etre imprimer quelque chose--vous m'obligeriez infiniment si vous pourriez me faire parvenir ce que vous avez ecrit sur ces idees. "J'ai enonce les memes idees sur la transformation des types ou origine d'especes que M. Darwin. (See Vol. I.) Mais c'est seulement sur la geographie zoologique que je m'appuie. Vous trouverez, dans le dernier chapitre du traite 'Ueber Papuas und Alfuren,' que j'en parle tres decidement sans savoir que M. Darwin s'occupait de cet objet." The treatise to which Von Baer refers he gave me when over here, but I have not been able to lay hands on it since this letter reached me two days ago. When I find it I will let you know what there is in it. Ever yours faithfully, T.H. HUXLEY. CHARLES DARWIN TO T.H. HUXLEY. Down, August 8 [1860]. My dear Huxley, Your note contained magnificent news, and thank you heartily for sending it me. Von Baer weighs down with a vengeance all the virulence of [the 'Edinburgh' reviewer] and weak arguments of Agassiz. If you write to Von Baer, for heaven's sake tell him that we should think one nod of approbation on our side, of the greatest value; and if he does write anything, beg him to send us a copy, for I would try and get it translated and published in the "Athenaeum" and in 'Silliman' to touch up Agassiz... Have you seen Agassiz's weak metaphysical and theological attack on the 'Origin' in the last 'Silliman'? (The 'American Journal of Science and Arts' (commonly called 'Silliman's Journal'), July 1860. Printed from advanced sheets of vol. iii. of 'Contributions to the Nat. Hist. of the U.S.' My father's copy has a pencilled "Truly" opposite the following passage:--"Unless Darwin and his followers succeed in showing that the struggle for life tends to something beyond favouring the existence of certain individuals over that of other individuals, they will soon find that they are following a shadow.") I would send it you, but apprehend it would be less trouble for you to look at it in London than return it to me. R. Wagner has sent me a German pamphlet ('Louis Agassiz's Prinzipien der Classification, etc., mit Rucksicht auf Darwins Ansichten. Separat-Abdruck aus den Gottingischen gelehrten Anzeigen,' 1860.), giving an abstract of Agassiz's 'Essay on Classification,' "mit Rucksicht auf Darwins Ansichten," etc. etc. He won't go very "dangerous lengths," but thinks the truth lies half-way between Agassiz and the 'Origin.' As he goes thus far he will, nolens volens, have to go further.
