Dear Charles

I find I cannot draw a ⊙ round your two points, as the difference is so small only about a $\frac{1}{\mathrm{70\; or\; 80}}$ of an inch.

I send you 2 more projections as the more points of view you see it in the better²

I also send you some rhombs cut out, with flaps to fasten over the edges, & I advise you to begin with the flap (A)³

They are not the same size as Millers,⁴ & I do not know if you have any reason for that particular size.

Also a pyramid, with 2 circles on the base to be raised up & the circle on the short diameter will show you exactly how much the obtuse ∠’s are within the sphere

12 of these pyramids would make the Dodec.

You will be surprized how firm the model will feel when put together, but dont be in a hurry & let one flap dry before you paste another,

When you have got the model in your hand, & hold them in the same position as my diagrames, they will all become quite clear.

I think I have answered all your questions.

Over the page I will draw another little diagram to fix the positions of the acute ∠^s
