To James Paget   4 June [1870]1

Down. | Beckenham | Kent. S.E.

June 4th

My dear Paget

You have been so kind in helping me that I think you will again.—2 Can you persuade the resident Doctor in some hospital to observe a person retching violently, but throwing nothing from the stomach.— When a person vomits violently, he always contracts the orbicular muscles round the eyes, & tears often flow. I have been discussing with, or rather enquiring from, Prof. Donders of Utrecht about the relation between the spasmodic contraction of the orbicular muscles & the secretion of tears. In the case of vomiting he suspects that irritating matter is injected into the nose & thus causes tears.3 From my own personal experience I do think that this is the case. Therefore what I want to know is whether in violent retching, with nothing ejected from stomach, when the orbiculars are strongly contracted, do the eyes fill with tears or even overflow?—4

Pray do not acknowledge this note & believe me | Yours very sincerely | Ch. Darwin
