From Rev.d J. Holme   24 March 1828

Dear Sir,

Direct the Parcel to me at Freckenham, to be left at the Waggon and Horses, Newmarket, to the Care of Mr. Wiseman.

It will give me great Pleasure to undertake the Analyses of Lord Braybrook’s Chalk Specimens, and I have little Doubt but I shall succeed in finding out the Cause of the different Effects which the two Limes produce on Soil, apparently, of the same Quality. I should say, a priori, that one Lime is more caustic than the other, and that this Property of Causticity varies inversely in Proportion to the Quantity of the Oxide of Iron and Alumina which each Lime contains in its Composition. But actual Expt must decide the Question and not Conjecture– Be so obliging as to tell our learned Friend Prof ^r Sedgwick that I have succeeded in detecting muriate of Lime, muriate of Mag ⁿ, & muriate of Soda in the red Magnesium Specimen which he gave me to examine.

I am dear Sir | yours truly | J. Holme
