To him, however, it was a labor of love; and he had succeeded in getting together a considerable mass of curious and valuable material _pour servir_. His last visit to his native country had researches of this nature for one of its objects; and we are sure many persons connected with the charitable institutions of Dublin, will recollect the persevering zeal with which he visited the haunts of poverty, as well as the asylums for its relief, noting down every thing which might prove afterwards serviceable on that suggestive topic.
