It seems possible that certain equi- librating impressions may be generated in the viscera themselves by means of the Pacinian cor- puscles. But if this is so, such impressions, being more or less correct, would be at variance with those formed in the main centre of equilibration,, and would but add another element to the general confusion. This class of vomiting is very violent,, and usually attended with many distressing symp- toms. It is common on the smaller craft, in a short angry sea, and may be regarded as the general type of channel-sickne&a. It is relieved on the same principle as Class 1, with the important addition of a tight bandage around the abdomen. Class 3.—The primary variety {a) is caused by the mechanical disturbance of the usually semi-fluid, contents of the stomach. It occurs most frequently in small boats, has no symptoms beyond slight paleness and nausea, and is usually relieved imme- diately by vomiting.
