1913My dear Miss Turner:
Draw the cut twice the natural size. We can reduce it to natural size on the block. This is not too small, is it?, to show the details. Try to get the drawing as clear as Figs 72 & 73 in my Introduction to Physiology, pages 556-558.
This paper will be practically all your own.
Faithfully
W. T. Porter
