To Adam Sedgwick 1 September 1845

O Sedgwick, Sedgwick - mark my prescience! Did I not rightly in saying I would fix no more days for Geological Professions of Geological Professors. "Tell Bunbury I will come before the end of August!" I told him no such thing; for having got a little rap for faithlessness before, I thought it best to wait & see what the end of August would produce. I suppose we must now give you up, like a horrid bad riddle. I must go to Town on Monday week to fetch Fanny & Ann from St Albans. Louisa & I took a drive to Felixstow last week & found a whale's Ear &what looks like a Cachelots tooth! I have got a large stack of the pseudo-coprolitic (?)(sic) nodules in their primitive condition from the London Clay at Colchester. Are they transformed bones?? Moreover I am pretty well satisfied that the highly mineralised Whales ears & bones in the Crag are derivatives from the London Clay - a matter of importance in clearing up the comparative climates of the 2 Epochs & accounting for the fortuitous jumble of 5 species in one limited spot. Harriet is considered as decidedly progressing though slowly & not yet venturing down stairs.

Ever affectly yrs

J. S. Henslow
