_Sensory disturbances._ On the sensory side the effect of emotions, particularly unpleasant ones, in awakening “thrills” and all sorts of sensations in different parts of the body is a matter of everyday observation. _Nausea_, _dizziness_, _headache_, _pains_ of different kinds are common accompaniments. Such reactions, however, largely vary as idiosyncrasies of the individual, and are obviously not open to experimentation or measurement. Whether they should be spoken of as physiological or aberrant reactions is a matter of terminology. They are, however, of common occurrence. In pathological conditions disagreeable sensations accompanying fear, grief, disgust, and other distressing forms of emotion often play a prominent part, and as symptoms contribute to the syndromes of the psychosis. The following quaintly described case quoted by Cannon from Burton’s Anatomy of Melancholy is as good as a more modern illustration: “A gentlewoman of the same city saw a fat hog cut up; when the entrails were opened, and a noisome savour offended her nose, she much disliked, and would not longer abide; a physician in presence told her, as that hog, so was she full of filthy excrements, and aggravated the matter by some other loathsome instances, insomuch this nice gentlewoman apprehended it so deeply that she fell forthwith a vomiting; was so mightily distempered in mind and body that, with all his art and persuasion, for some months after, he could not restore her to herself again; she could not forget or remove the object out of her sight.” Cannon remarks: “Truly, here was a moving circle of causation, in which the physician himself probably played the part of a recurrent augmenter of the trouble. The first disgust disturbed the stomach, and the disturbance of the stomach, in turn, aroused in the mind greater disgust, and thus between them the influences continued to and fro until digestion was impaired and serious functional derangement supervened. The stomach is ‘king of the belly,’ quotes Burton, ‘for if he is affected all the rest suffer with him.’” Such cases could be multiplied many fold from the records of every psychopathologist. I happen by chance to be interrupted while writing this page by a patient who presents herself suffering from a phobia of fainting. When this fear (possibly with other emotions) is awakened she is attacked by nausea and eructation of the gastric contents, and, if she takes food, by vomiting of the meal. (Owing to a misunderstanding of the true pathology by her physician, her stomach was washed out constantly for a period of two years without relief!)
