This concise and well-written book describes a great many odd particles found in the blood of normal people. It is notable on at least three scores.

These various particles, as large as 100 microns in size, are termed "embolic dispersoids." They may contribute to increased viscosity of the blood and perhaps even to sludging and plugging
