De anima brutorum quae hominis vitalis ac sensitiva est, exercitationes duae. Prior physiologica ejusdem naturam, partes, potentias & affectiones tradit ; altera pathologica morbos qui ipsam, & sedem ejus primariam, nempe cerebrum & nervosum genus afficiunt, explicat, eorumque therapeias instituit, cum figuris
Thomas Willis's 1672 Latin treatise on the animal soul, printed in London by Gulielm. Wells and Rob. Scot for physicians and medical students, with its physiology and disease exercises illustrated by engraved plates. The plates show branching vascular and nerve trees, a dissected brain seen from above, and an insect's head and mouthparts with a jointed leg, drawn in precise line with lettered reference marks that a designer could borrow for diagrammatic or scientific graphics.
