To these observers the microscope revealed the fact that if a minute drop of human blood is placed between two plates of glass, the red corpuscles apply themselves to each other by their concave surfaces in such a manner as to form long cylindrical masses, which resemble piles of coin, and that very frequently these piles are so arranged as to form with each other a complete network of rouleaux with clear intervening spaces occupied by liquor sanguinis. Simple as this observation may appear, its importance in a pathological point of view can scarcely be overrated ; for upon its correct interpretation depends our knowledge of the real nature of one of the most marked cha- racteristics of inflammation, viz. the phenomenon of inflammatory or homo- geneous stasis. During the forty years which have elapsed since the discovery of this
