Even after a moderate strong fit of ordinary coughing, almost everyone has to wipe his eyes. I have seen In violent vomiting or retching, as I have seen myself experienced & heard from seen in others, the orbicular muscles are strongly contracted & tears sometimes flow freely down the cheeks. It was has been suggested to me that this may be due to irritating matter being injected into the nose, & thus by reflex action causing the secretion of tears.

Accordingly I asked one of my informants, a surgeon, to attend to the effects of retching when nothing nothing was thrown up thrown up from the stomach; & by an odd coincidence, he himself suffered the next morning from an attack of retching & saw within three days subsequently observed a lady under a similar attack, & he is certain that not an atom of matter was ejected in either case from the stomach; yet the orbicular muscles were strongly contracted & tears freely secreted. I can also speak positively to the strong energetic contraction of these same muscles & to the coincident free secretion of vigorous tears, when the abdominal muscles act with unusual force in a downward direction on the intestinal canal.)
