"I should be writing a third paper on the Nerves, but I cannot proceed without making some experiments, which are so unpleasant to make that I defer them. You may think me silly, but I cannot perfectly convince myself that I am authorised in nature, or religion, to do these cruelties—for what?—for anything else than a little egotism or self-aggrandisement; and yet, what are my experiments in comparison with those which are daily done? and are done daily for nothing. So my employment is, correcting the press of my new edition of the Anatomy, and writing notes for my Physiology, which I mean to make an additional volume to the Anatomy."

"In concluding these papers, I hope I may be permitted to offer a few words in favour of anatomy, as better adapted for discovery than experiment. … Experiments have never been the means of discovery; and a survey of what has been attempted of late years in physiology, will prove that the opening of living animals has done more to perpetuate error, than to confirm the just views taken from the study of anatomy and natural motions."
