Translations for constitution in French

Here are paragraphs from public domain books translated:

"About sixty; but his constitution has been shattered by his life abroad, and he has been in failing health for some time. This business has had a very bad effect upon him. He was an old friend of McCarthy's, and, I may add, a great benefactor to him, for I have learned that he gave him Hatherley Farm rent free."	— Environ soixante ans, mais sa constitution a été ébranlée par son séjour dans les colonies et sa santé décline depuis quelque temps. Cette affaire l’a très vivement impressionné. C’était un vieil ami de M. Mac Carthy et je puis même ajouter un bienfaiteur, car je viens d’apprendre qu’il n’exigeait pas de fermage pour la location de Hatherley Farm.
