Has read [Joseph] Sabine's paper and concurs with him in everything, except for minor changes to specific names. Sorry he gave Macleay "such a kettle of fish", had hoped it would be better. Hopes to be in London on 6 May [1823] but very unwell at present, being threatened with a pulmonary irritation and "a bad state of bowels". Macleay to "throw the Cornish paper aside if not quite worthy to appear".
