Has been busy writing all winter including business and botanical letters and finishing his part of Rees' "Cyclopaedia", now at 'Yucca'. Interrupted for some weeks by a "very severe & obstinate bowel complaint" that began with vertigo, which many have had this winter, recovered but now labouring under a bad catarrh. Confident about his Cambridge prospects regarding the garden and Walker's lectureships; Dr [Martin] Davy says the new Professor of Physic [John Haviland (1785-1851)] has promised his vote as one of the five trustees and sure of two more, has written to vice-chancellor but has not heard anything for six weeks, if possible would like to give a course of lectures this spring.
