Every anatomist and every anatomical work declares that from the roots no twig proceeds either to skin or muscles ; and if it were not obvious that the Doctor had mis- taken the branches for the roots, I should be apt to think that in his ' careful examination of the structure of the spinal mass of nerves,' the Doctor had refuted the whole of them. I have now to mention, that even some of those anatomists who succeeded Willis conjec- tured that there were cerebral and cerebellic nerves. They indeed only conjectured this; and they, moreover, erred by distinguishing them into vital and animal. The vital nerves, said they, are chiefly derived from the cerebellum, and the animal from the cerebrum. [Sir C. Bell's doctrine of 1811 was absolutely no more than this!I/] They have believed, says Haller, that several nerves have roots partly from the cere- bellum. But Haller objects that the fifth pair [tri- facial] arising, as he says, from the cerebellum, is appropriated both to sense and motion. He shows also, that some of those nerves which they be- lieve to have some origin from the cerebellum, have nothing to do with vitality ; and he ad-](https://iiif.wellcomecollection.org/image/b21274010_0096.jp2/full/800%2C/0/default.jpg)
