To J. H. Balfour   5 June 1854

My dear Sir,

I have delayed writing till my lectures were over that I might send you this syllabus corrected so far as I might see errors during my lectures – It was prepared during my last course for those who attend for a pass examination, & you will see I have divested it of several tabular views which were in the former & which were rather more than our mere pass men could digest in a short course - The Demonstrations at the end are rather for the initiation of those who want to work a little during the long vacation – for several some of them belong to flowers that are not out yet- I have received a map of the great Dracaena of Orotava, & have cut off a section which may be subdivided in 2 or 3 slices when thoroughly dry _ Stratton has suggested that you may like to have one if you have it not already – The fibres are concentrically arrange somewhat after the manner of an [illeg.] - & there is a sloughing of the surface which looks like a genuine bark. I found the 2 ^d part of your excellent Class Book waiting for me on the shelf at M^cMillans Shop, & I believe several of my Class have procured it _ I had a pleasant excursion with 2 doz. of them to Ely last week – but most of the few plants are late, & we did not get many things in flower– I was rather curious to know whether I should be able to stand my lecture & pay to & fro for duty here- but I am happy to be returned much better than when I first went, & hope I have pretty thoroughly recovered from my late unpleasant attack, state to be dyspepsia from neuralgic affection arising from over work –

Yrs very truly

J S Henslow
