From William Buckland   11 July 1845

My Dear Henslow

I am gratified by your adhesion to my anticoprolitic Theory and your Pseudo Coprolites must be mortified by their Rejection from the Honor of Genuine dignity and [illeg.] to which your fair hand promoted them

I can hardly venture to indicate without some Experiments how the imposters acquired their Phosphorus— I suspect it was from keeping bad Company at the Bottom of the Crag=producing Seas— I can hardly impute to the dulse the Honor of affording the requisite supplies

I now suggest as an Experiment— to make some Balls of Roman Cement & Balls of Rounded Septaria from London Clay & lay them in fluid & pulpy Coprolite matter obtained from recent fishes for a few weeks to see if such Balls will absorb Phosphorus

I do not expect to be in London next Friday, should I be so, I will enquire for you at the G.S. Sedgwick has been at the [illeg.] Bishop of Yorks since Oxford & Williams The Dean of Ely & London strangers to me in Oxford

Believe me | Yours Very Truly| W ^m Buckland
