    considered by any means as demonstrative of the fact. T'hey shew that digestion ceases when the erghth pair of nerves, is divided ; but, as car- culation and respiration are extensively influ- enced by this operation, it cannot be doubted, that this physiologist has remarked the functional dis- order produced, and has ascribed at, without due consideration, to the immediate loss of nervous energy belonging to the stomach. That the principles, which this physiclogist has deduced from his experiments, are falla- cious, is not difficult to prove. In a work, which I lately published, it was satisfactorily shewn, that the division of the eighth pair of nerves is injurious to the digestive powers of the stomach, en proportion only to the disorder enduced in those of resmration and circulation.* When these were protected by the introduction of a small tube into the divided trachea, which enabled the animal to breathe with facility, digestion proceeded as correctly, although a portion of the nerve on each side was excised, as when the nerves were left entire; the trachea alone being separated, and a tube attached, as in the preceding instance. * See an Experimental Enquiry into the Laws which regulate the Phenomena of Organic and Animal Life.
