Le physicien anglais John Henry Poynting accepte de publier un article.

John Henry Poynting donne son accord pour publier un article dans la Revue générale des Sciences. "I do not know whether I have any right to consent to the publication of the paper I have sent to the Congrès International de Physique for I suppose it is really the property of the Congrès. But if my consent is sufficient I need hardly say that I shall be delighted to agree to its publication in the Revue Générale".
