To William Buckland 10 January 1833

My dear Sir,

Your argument is quite conclusive about the trees in Portland not being illustrated by the case at Chalbury - from the general appearance of the latter however, & the slight traces of organizn. throughout the flinty cylinder I think the original size of the mass was marked by the dimensions of the cylinder - but we can argue nothing from it as I never found the trees in Portd. simy. encrusted. The idea struck me whilst I was writing to you & I did not remark the want of analogy. Don't return the specimen nor yet the Zamia Cone they are both at your service - & I can send a few more fragments of one sort or another when Sedgwick has helped himself - which you may keep or throw away - but pray don't return them as I am very glad to get them out of my house. I always pump away for some time before I take the temperature of water in a pump. I am just about to enter the Senate house as an examiner in Paley & have no time to say more.

Yrs very truly

J. S. Henslow
