    • 1830, John Davy, Observations to endeavour to ascertain if Dead Animal Matter absorbs Air on exposure to the atmosphere: The Edinburgh Medical and Surgical Journal, volume 34, page 247:
      Though air is excluded from venous blood the instant it is drawn, as by receiving it in fresh white of egg, milk or serum, in which it immediately sinks, nevertheless on coagulation the surface of the crassamentum will be of a comparatively light florid hue.
    • 1831, John Burns, The Principles of Surgery[1], page 91:
      If healthy blood be allowed to remain at rest, it separates into two parts, a red solid portion called crassamentum, and a thin watery part or serum. [] This shows that the proportion of fibrin in the crassamentum does not vary rapidly.
    • 1845, Emanuel Swedenborg, The Economy of the Animal Kingdom[2], volume 1, page 71:
      Such as are the volumes, such are the crassamenta belonging to the volumes, and such also are the masses ; that is to say, if the volumes are pure, mixed homogeneous, or mixed heterogeneous, such respectively are the crassamenta and the masses.
