To William Buckland 16 July 1845

My dear Buckland,

In passing through Colchester yesterday I procured some of the nodules in the Parental State from the London Clay & shall leave a little packet of them at the geological society for you on Friday. I should like some day to make a remark respecting them & the whale ears - for I feel now pretty well satisfied that the latter are also derivatives - which explains a considerable mystery about the manner in which they occur. 4 or 5 species (according to Owen) within so small a compass. The rolled state of the Cetacean bones in the Crag all tend to the same operation. It is evidently of great importance not to give these remains to a wrong Epoch. Aberrant Sedgwick put us all in confusion last week by not keeping his appointment - but his eccentric orbit has been so long known that we never wonder at anything from him in the way of oblivion.

Ever yrs truly

J. S. Henslow
