My dear Father,

After a most tremendous rummage I found the 2 Roy. Soc. books & took them back;² I had almost given one of them up when I found it stuck away under a pile of papers in a cupboard. I have also been to see M^r. Cook³ & have discovered what you probably will have heard by telegraph (a useful exercise to Aunt C.)⁴ that the Heliotype people put 2^s 2$\frac{1}{2}$ ^d by mistake for 1^s.2$\frac{1}{2}$^d— this correction makes the prints very cheap instead of very dear 1^d a piece. I empressed on Cook that he was to get them to charge a lump sum for preparing plates &c including the titling & that as far as we can see it is absurd to charge per 100 for doing it. Cooke says that he does not consider them sharp-practitioners but v. liberal & thinks it all very satisfactory

I met Pryor⁵ here this p.m & we are going down to Brighton together, wh will make it much more lively.— There had been an accident on the G.E.R this a.m   a train ran off the lines on the viaduct near New Cross   luckily it had run straight on & no harm was done.⁶ I shall prob. turn up on Sat.— I hope you have got thro’ the journey well⁷
