Translations for to say nothing of in French

Here are paragraphs from public domain books translated:

"As far as you are personally concerned," remarked Holmes, "I do not see that you have any grievance against this extraordinary league. On the contrary, you are, as I understand, richer by some £30, to say nothing of the minute knowledge which you have gained on every subject which comes under the letter A. You have lost nothing by them."	— Pour votre part, remarqua Holmes, je ne vois pas que vous ayez à vous plaindre de cette extraordinaire association. Vous êtes au contraire de trente livres plus riche, sans compter la science complète que vous avez pu acquérir sur les mots commençant par la lettre A. Vous n’avez donc rien perdu.
