1. Vol 1 The Gravity Outfit and the Head of the Column What a gravity injection outfit is — an elevated glass reservoir, rubber tubing, a stopcock, and an arterial cannula — and the founding idea of arterial embalming: that its pressure is the weight of a raised fluid column, not the push of a pump.
2. Vol 2 Head Pressure, Materials, and Survival Why a bottle on a stand is a pressure source at all — the hydrostatic physics of the gravity outfit, the blown glass, gum rubber, and brass it was built from, and why the rigs that survive are almost always missing half their parts.
3. Vol 3 The Chemists, the War Dead, and the Making of a Trade How arterial injection crossed from the French anatomy schools of Gannal and Sucquet to the battlefields of the American Civil War — and how Thomas Holmes, Colonel Ellsworth, and Lincoln's funeral train turned a dissecting-room technique into a national industry.
4. Vol 4 Preserved Because Poisonous The metal-salt fluids — arsenic, zinc, and mercury — that made gravity-injection embalming work, why their preservative power was inseparable from their toxicity, and the long public-health reckoning that banned them and left arsenic in old cemetery soil.
5. Vol 5 Collecting, Dating, and Displaying a Gravity Rig How a collector recognises a gravity injection outfit, reads its condition and provenance, dates the glass and its fittings, and displays one safely — and where these objects sit in the funeral-history collecting world.
