The handwriting in that drawing is beautiful!
It looks pretty but it's so low resolution I can barely make out any words. Found a higher res version though (embedded in a PDF, page 7):

It's interesting that all lines in the sketch are straight, and circles are perfect, so it seems Whitfield took a ruler and a compass on that plane.
