Moby Dick Ch. 77: The Great Heidelberg Tun

The following is from a work-in-progress called "Moby Dick: a Book Report" in which I read each chapter of Herman Melville's classic novel Moby Dick, and write about what I read.

This is yet another chapter describing the Sperm Whale’s head.  The upper part, called the “case” contains the purest concentration of spermaceti oil of anywhere on the whale.  It generally yields about 500 gallons of oil, or sperm.  Ishmael compares it to "The Great Heidelberg Tun" which is a giant wine vat contained within the cellars of the Heidelberg Castle in Germany.
