THE SPARROWS. K The London Bvilder says: One hundredand eighteen Sparrows havo been ofibred uponthe altars of science. Tlio contents of the stom-achs of the victims have been examined, tabu-lated and recorded. Three culprits alone, outof this hecatomb, were proved by the unsparingsearch, guilty of having lived for the past four-and-twenty hours upon grain.
