Correspondence. A letter to Gordon Zahn. ~ Emile thanks Gordon for his letter of March 13th and informs him that his paper has been included in the proceedings of the Montreal meeting. The papers will not be read by their authors. Instead, an "animator" will point out the similarities and divergences between a group of 4 or 5 papers and discussions will follow. Though Gordon does not have to personally read his paper, they would like him to be present.
