Translations for classification in French

Here are paragraphs from public domain books translated:

"Exactly. A rough classification may be the best that we can attempt. To-morrow some further evidence may help us to an identification. Meantime we can only renew our interrupted slumbers."	— Et nous ne devons pas, en effet, prétendre à mieux qu’à une classification sommaire. Demain nous apportera peut-être des éléments d’identification. En attendant, reprenons notre sommeil.
The Lost World, by Arthur Conan Doyle	Le Monde perdu, de Arthur Conan Doyle
