This prayer offered by Rabbi Sabato Morais in response to what became known as the Great Chicago Fire was offered at the end of his sermon reprinted in The Philadelphia Inquirer on the following day 1 December 1871. It was preserved by Rabbi Morais in his ledger (page 47), an archive of newsclippings recording material he contributed to the press, among other announcements. (Many thanks to the Library of the University of Pennsylvania for helping to make this resource accessible.)
