" All bodies have spirits and pneumatical parts within them; but the main differences between animate and inanimate, are two: the first is, that the spirit of things animate are all contained within themselves, and are branched in veins and secret canals, as blood is; and, in living creatures, the spirits have not only branches, but certain cells or seats, where the principal spirits do reside, and whereunto the rest do resort: but the spirits in things inanimate are shut in, and cut off by the tangible parts, and are not pervious one to another, as air is in snow.Bacon’sNatural History,No 601.
