G. F. Secchi de Casale, editor of the well-known Eco dâItalia--from whom I obtained full and trustworthy information. A series of articles contributed by Mr. De Casale to his paper, on the Italian street children, in whom he has long felt a patriotic and sympathetic interest, I have found of great service, and I freely acknowledge that, but for the information thus acquired, I should have been unable to write the present volume.
