Chapter 77
The Great Heidelburgh Tun
The Great Heidelburgh Tun. Now comes the Baling of the Case. But to comprehend it aright, you must know something of the curious internal structure of the thing operated upon. Regarding the Sperm Whale’s head as a solid oblong, you may, on an inclined plane, sideways divide it into two quoins,* whereof the lower is the bony structure, forming the cranium and jaws, and the upper an unctuous mass wholly free from bones; its broad forward end forming the expanded vertical apparent forehead of the whale. At the middle of the forehead horizontally subdivide this upper quoin, and then you…

Key Quotes & Analysis
"Now comes the Baling of the Case. But to comprehend it aright, you must know something of the curious internal structure of the thing operated upon."
Context: Chapter opening
Procedure demands anatomy first; economics follow structure.
In Today's Words:
Ishmael opens by saying baling of the Case is next but you must first learn the curious internal structure of the sperm whale head operated upon. Extraction without map wastes the vintage and spills gallons you cannot recover. Every premium harvest needs a diagram before buckets touch liquid.
"The upper part, known as the Case, may be regarded as the great Heidelburgh Tun of the Sperm Whale."
Context: After junk honeycomb defined
Domestic cask metaphor makes sacred oil legible to merchants.
In Today's Words:
After describing junk honeycomb Ishmael calls the upper unctuous mass the great Heidelburgh Tun of the sperm whale with plaited forehead devices like carved tierce fronts. The metaphor turns anatomy into inventory theology. This is the reservoir Apex will tap next chapter with buckets and risk.
"namely, the highly-prized spermaceti, in its absolutely pure, limpid, and odoriferous state. Nor is this precious substance found unalloyed in any other part of the creature."
Context: Case contents versus junk
Exclusive vintage justifies ticklish baling and later accidents.
In Today's Words:
The tun holds highly prized spermaceti pure limpid and odoriferous, found nowhere else unalloyed in the whale. Fluid in life, it concretes into crystalline shoots in air after death. That exclusivity is why operators must be heedful and why a fall into the Case is a precious perishing.
"Thus much being said, attend now, I pray you, to that marvellous and almost fatal operation whereby the Sperm Whale’s great Heidelburgh Tun is tapped."
Context: Chapter close after depth and tackles
Cliffhanger into Ch 78 danger; heedfulness theme continues.
In Today's Words:
After measuring twenty-six feet of tun depth and warning decapitators not to waste the magazine, Ishmael asks you attend the marvellous almost fatal tapping operation coming next. Anatomy ends where circus begins. Tashtego will run the yard-arm, the ship will reel, and buckets will learn how dangerous premium is.

Discussion Questions
This is not a test. Five prompts guide you through the chapter, from how it opens to how it closes, so you notice context and rhythm rather than facts to memorize. Sit with each question in your own words. When you see "One way to read it," treat it as a starting point, not the only answer.

Chapter 78: Cistern and Buckets
Tun mapped, Tashtego runs the yard-arm whip: buckets, baling, and the accident that drops him into the Case Next: Cistern and Buckets. Tashtego runs the mainyard-arm like a cat, drops by whip tackle onto the hoisted tun, spades for the tap, and baling fills tubs with bubbling sperm until the pole must ram twenty feet deep.
