20 May 1863

My Dear Sir

Th I find that the woodcuts for both your papers have been already executed. In these circumstances I suppose that I must hand over those for the paper on the theory of parallels ^<1> to you, so that you may return them if you choose for a future occasion

Your paper on Fagnani’s Theorem ^<2> will be in type immediately. It would be well if you could revise it in proof before leaving for the Continent. Let me know if you can do so & also inform me as to your wishes relative to the other Woodcuts

I am yours sincerely
J. H. Balfour
