Oppel, Neumayr, and yourself will confer a lasting and admirable service on the noble science of Geology, if you can spread your views so as to be generally known and accepted.
With respect to the continental and oceanic periods common to the whole northern hemisphere, to which you refer, I have sometimes speculated that the present distribution of the land and sea over the world may have formerly been very different to what it now is; and that new genera and families may have been developed on the shores of isolated tracts in the south, and afterwards spread to the north.
LETTER 286.

TO J.W.JUDD.

Down, June 27th, 1878.
I am heartily glad to hear of your intended marriage.

A good wife is the supreme blessing in this life, and I hope and believe from what you say that you will be as happy as I have been in this respect.

May your future geological work be as valuable as that which you have already done; and more than this need not be wished for any man.
