From Horace Darwin to Emma Darwin [1881?]

Tell George that the tub for the Pendulum is made & I am going to get the window put in at once. & that I have paid Mr. Wales. Now I think you have had a big enough dose of Shop. Tell Father that the Cambridge Scientific Instrument Company hopes that he will do them the honour of accepting the small bottle of clock oil as a present from them. Φ has had such a wonderful affect on Hope that she not only will mention Dubbas name but even will tell a story about him!! I shall have a dose of Φ worship next Sunday I guess.

Yours ever affect son | Horace Darwin
