OUR theory. My sole merit in the matter (and for that I do take some
credit) is to have set him at work at it, for the only suggestion I
made, namely that the veined structure was analogous to his artificial
cleavage phenomena, has turned out to be quite wrong.

Tyndall fairly MADE me put my name to that paper, and would have had it
first if I would have let him, but if people go on ascribing to me any
share in his admirable work I shall have to make a public protest. All I
am content to share is the row, if there is to be one.

Berne, September 3, 1856.

I send you a line hence, having forgotten to write from Interlaken,
whence we departed this morning.

The Weissthor expedition was the most successful thing you can imagine.
We reached the Riffelberg in 11 1/2 hours, the first six being the
hardest work I ever had in my life in the climbing way, and the last
five carrying us through the most glorious sight I ever witnessed.
During the latter part of the day there was not a cloud on the whole
Monte Rosa range, so you may imagine what the Matterhorn and the rest of
them looked like from the wide plain of neve just below the Weissthor.
It was quite a new sensation, and I would not have missed it for any
amount; and besides this I had an opportunity of examining the neve at a
very great height. A regularly stratified section, several hundred feet
high, was exposed on the Cima di Jazi, and I was convinced that the
Weissthor would be a capital spot for making observations on the neve
