Yet for the reasons stated, he never did so.
About a fortnight after the flower episode a chance came Godfrey's way of making an Alp-climbing expedition in the company of some mountaineers.

They were friends of the Pasteur who joined the party himself, but stayed in a village at the foot of the mountains they were to climb, since for such exercise he had lost the taste.

The first two expeditions went off very successfully, Godfrey showing himself most agile at the sport which suited his adventurous spirit and delighted him.

By nature, notwithstanding his dreamy characteristics, he was fearless, at any rate where his personal safety was concerned, and having a good head, it gave him pleasure to creep along the edge of precipices, or up slippery ice slopes, cutting niches with an axe for his feet.
Then came the third attempt, up a really difficult peak which had not yet been conquered that year.

The details of the expedition do not matter, but the end of it was that at a particularly perilous place one of the party lost his head or his breath and rolled from the path.
There he lay half senseless, on the brink of a gulf, with a drop of a thousand feet or more beneath him.
