From Lord Braybrooke   20 March 1828

Dear Sir,

Will you be so good at your leisure to get some Chemist to analyze the 2 specimens of Chalk which accompany this note & to report to me as to their qualities. One came from my Berks Estate & is there much used as a manure for clay lands, the other from this place, has been also put on clay lands in this neighbourhood & without producing any benefit. I am anxious therefore to be able to account for these very different results.

L ^y B writes with me in compliments to M ^rs Henslow & yourself

Believe me | D ^r Sir | Y ^rs faithfully | Braybrooke
