Letters from Constantinople mention a disagreeable occurrence, which has compelled
Lord PONSONBY, our Ambassador, to as- sume a somewhat threatening attitude towards the Porte. Mr. CHURCHILL, an English merchant, accidentally wounded a Turkish boy, while quail-shooting : he was seized by the Turkish authorities, severely bastinadoed, put in irons, and imprisoned. Lord PONSONBY interfered, and obtained an order for his release from the Reis Effendi : but this order was countermanded, and Mr. CHURCHILL detained; whereupon Lord PONSONBY has in- formed the Porte, that all communication 'between himself and the Turkish Government must be at an end until redress is granted. And there the matter rested when the last accounts were sent off, on the 11th of May.
