Monday sketchbook: Tithing settlement

In the Church, we make an accounting of our tithing to the bishop of the ward at the end of each year. In the old days, people used to pay tithing in kind (rather than monetarily) with their flocks or produce or whatever. Since by definition a tithe is ten percent, I wondered how Dr. Frankenstein might do an in kind donation? Ten percent of his spare body parts? Luckily, I abandoned this idea before it progressed much further.
