Method for a clear distillation with a cooled alembic
A still whose whole alembic is surrounded by running water
An irregular fragment of paper carries a note and a sketch of distillation apparatus: a rounded still with a domed head set on a base, drawn beside a smaller detail. The text gives a method for obtaining a clear distillate by making water run so that it surrounds the whole alembic, cooling it. The lower right corner is a stained loss in the sheet.

Cooling the alembic with running water
The note describes a way of making a clear distillation: let the water run so that it surrounds the entire alembic. The sketch below shows a rounded still with a domed head on a low base.
Water circulating around the vessel
The clarity of the distillate depends on water flowing all around the alembic to keep it cool. Channels and the body of the vessel are sketched below the note.
