He had no cough; in fact, he was afraid to cough, on account of the throat-spasm. He was ordered a dose of castor-oil, and bromide of potassium, 3j ; tincture of belladonna, TTpx ; dilute hydrocyanic acid, rr\ij; and compound tincture of chloroform, tt]x, in water every four hours. He inhaled steam with two drachms of hemlock-juice in it. About half-past three another severe paroxysm came on, but soon subsided, and the spasms became less frequent. In a few days he recovered, and there has been no return of laryngeal or other sym- ptoms of disease since—now five years ago. This severe form of disease was spasm of the glottis, and closely resembled the laryngismus stridulus which is more frequently found at an earlier age. It was evident that there was irritation either of the pneumogastric nerve at its root, or of the recurrent laryngeal nerve ; it was a neurosis of the larynx, and a condition of hyperaesthesia ; and it was due, not to any local change in the part, but to an affection of its nerves. This, in fact, is the pathology of laryngismus stridulus; sometimes it is due to mis- chief at the origin of the nerve, and the spasm of the glottis is a slight convulsion, which may be followed by a more general one, the fingers and the toes being turned in, as in membranous inflammation](https://iiif.wellcomecollection.org/image/b24975151_0035.jp2/full/800%2C/0/default.jpg)
