Before photography was developed, doctors could only depend on each other's written descriptions and drawings to communicate what to look for in a scarlet fever rash, or how consumption affects the lungs.

We've collected a few of these drawings here. Consider them a companion to our seven favorite vintage anatomy drawings, which show healthy skeletal, vascular and other body systems.
