456   Life and Letters of Francis Galton


DEAREST MOTHER, The grouse won't come just now. All those killed as yet Fazakerly of course disposed of. He may give us some few to send soon; if he does I trust they will arrive safely at Claverdon. He is a capital fellow. I enjoy myself more than I have for a year and a halfeverything is so free and open. I stay with him till he goes if I like. His son, Col. Wallington and Paddy Johnson are the party. Louis Napoleon was to have come too but was prevented. We have every variety of field sport,-pitch tents and hack ponies.-Johnson stuck a dog into me to buy (Emma will explain, if I am not intelligible), it has proved a beauty and I with my one dog see more game than my fellow guests with two each. Shouldn't you like to buy him at the end of the grouse season? He would find you hares so well in Paul's Piece and I would part with him to my Mother (mind, only to my Mother) for the money I gave for him (£1O). Write me

an occasional note and tell me how Lucy is, for I am most anxious to hear.

Ever your affectionate Son, FRANK GALTON.

The heather is beautifully out on the moors-I pulled a piece to send to you as a memento but I have lost it. Lots of fishing and really of everything. It is a most civil thing of Fazakerly asking me.

Letters and note-books are very scant during the years that followed Galton's marriage. Probably like other husbands, he left correspondence to his wife.

Tea Making, My Experiments [IS 59].

There are among Galton's papers and note-books accounts of various experiments made by him, scarcely with a view to publication, but rather with the purpose of amusing himself and gratifying his insatiable desire to observe and measure. One especially characteristic series of experimental measurements dates from early in 1859, and deals with the

"Flavour, Freshness, Body and Softness" of Tea.

The experiments were made morning and evening, and must have tried severely the. patience of Mrs Galton, and not unlikely of the household. Galton begins with the following preliminaries

"The teapot holds 26 ounces= 31 breakfast cups. One breakfast cup holds 8 ounces. The teapot requires 3 minutes to become warmed through. It radiates heat at the rate of 2° per minute."

Then we have the categories to be used

G =good, B =bad, D=decocted, W =weak, F=flavour, C = body, a = best, b = 2nd best, c = 3rd best.

We next proceed

"To find the capacity for heat of the teapot.

n = number of ounces of water used,

e = excess of its temperature above that of the teapot,

t =additional temperature attained by the pot after the water has been poured in,

C =required capacity,

C+ne=(C+n) t, C=n (e-t)~(t-1)."

I will give a few illustrations from the notes which extend through February and March.
