Dear Ramsay

I am very much obliged for your interesting note, answering all my queries so clearly. I am sorry about Siberia.—² I sh^d like to put in some such sentence as following, & if I do not hear to contrary, I will do so.—

“Traces of life have been observed in the Longmynd beds, beneath Barrande’s primordial zone, & fossils have quite recently been discovered, as I hear from Prof. Ramsay, in the Laurentian marble of Canada, which is the oldest known formation in N. America, & believed to be lower than the Longmynd seriess.”—³

If I do not hear, I will assume that you do not object & think the case sufficiently clear to be put in in this general way.—

Believe me | Dear Ramsay | Yours very sincerely | C. Darwin

Do not forget that with your knowledge of Glacial action two days at Glen Roy would for ever settle the question which has nearly driven so many of us mad.— If at any future year you were persuaded to go there, I sh^d like to draw your attention to one or two little points.— I sh^d so like to see the case settled, even if it proved me ever so egrigiously wrong.—⁴
