Translations for classical in French

Here are paragraphs from public domain books translated:

"That, of course, explains it. Let me see; you have given me your promise that my confidence will be respected? That confidence, I may say, will be far from complete. But I am prepared to give you a few indications which will be of interest. In the first place, you are probably aware that two years ago I made a journey to South America—one which will be classical in the scientific history of the world? The object of my journey was to verify some conclusions of Wallace and of Bates, which could only be done by observing their reported facts under the same conditions in which they had themselves noted them. If my expedition had no other results it would still have been noteworthy, but a curious incident occurred to me while there which opened up an entirely fresh line of inquiry.

— Tout s’explique. Voyons, vous me promettez de garder pour vous ma confidence ? Elle sera d’ailleurs fort incomplète. Je m’en tiendrai à quelques indications. En premier lieu, vous devez savoir qu’il y a deux ans, je fis dans l’Amérique du Sud un voyage appelé à rester classique devant la science. Je me proposais de vérifier certaines conclusions de Wallace et de Bates, ce qui ne m’était possible qu’en observant les faits rapportés par eux dans des conditions identiques à celles où ils les avaient observés eux-mêmes. N’eût-elle pas eu d’autres conséquences, mon expédition eût déjà mérité l’attention. Mais il m’arriva là-bas un incident qui ouvrit une direction nouvelle à mes recherches.
