There is, on an average, one of these white corpuscles to every four hundred of the red corpuscles ; they are usually considerably larger, in human blood, than the red corpuscles, although they vary greatly both in size and appearance. Each possesses one or more nuclei; some are vacuolated, and others granular, while others ^ A cubic millimetre has about the volume of a large pin's head.
