On page 308 the second sentence of the third paragraph: "For example...every other", gave me the impression on first reading that all the ''rectangles'' in figure 27 chapter 6 would look the same to Poincarites, but of course Needham says each black ''rectangle''.
To make it even clearer I think it would be better to say that to the Poincarites, all ''rectangles'' belonging to the same ''ring'' are the same shape and size. So they see a picture like figure 29b chapter 3 on page 163, but centred at $a$ not the origin.
Maybe this was clear to you from the start, but I thought I was missing something.
