From F. S. B. F. de Chaumont to W. E. Darwin   7 May 1871

My dear Darwin,

I have not forgotten the question about the pupil in the cold stage of ague—¹ As I told you we had several cases brought into hospital sometime ago,—but my own duties prevented me seeing them much, so that I only saw one case in which it seemed to me that the pupils were dilated:— but the observation was not worth much as the man was obviously emerging from the cold stage— I however called Dr Fyffe’s att⁠⟨⁠e⁠⟩⁠ntion to the matter & as he ⁠⟨⁠is⁠⟩⁠ in charge of the medical ⁠⟨⁠r⁠⟩⁠ounds he has had better opportunity— He tells me he has been fortunate enough to see two cases in the cold stage well-marked,—and in each case the pupils were distinctly dilated—²

Yours v⁠⟨⁠er⁠⟩⁠y truly | F. de Chaumont

W. E. Darwin Esq^r.
