[After parting company with Hooker, he paid a flying visit to Professor Bonnet at Geneva; then he was joined by his wife and son for the last three weeks of the holiday, which were spent at Baden and in the Bernese Oberland. Before this, he writes home:—]

I feel quite a different man from what I was two months ago, and you will say that you have a much more creditable husband than the broken-down old fellow who has been a heart-ache to you so long, when you see me. The sooner you can get away the better. If the rest only does you as much good as it does me, I shall be very happy.

Axenstein, Luzerne, August 24, 1873.

My dear Tyndall,

The copies of your booklet ["Principal Forbes and his Biographers.">[ intended for Hooker and me reached me just as I left Baden last Tuesday. Hooker had left me for home a fortnight before, and I hardly know whether to send his to Kew or keep them for him till I return. I have read mine twice, and I think that nothing could be better than the tone you have adopted. I did not suspect that you had such a shot in your locker as the answer to Forbes about the direction of the "crevasses" referred to by Rendu. It is a deadly thrust; and I shall be curious to see what sort of parry the other side will attempt. For of course they will attempt something. Scotland is, I believe, the only country in the world in which you can bring in action for "putting to silence" an adversary who will go on with an obviously hopeless suit. The lawgivers knew the genius of the people; and it is to be regretted that they could not establish a process of the same sort in scientific matters.

I wrote to you a month ago to tell you how we had been getting on in France. Hooker and I were very jolly, notwithstanding the heat, and I think that the Vivarrais is the most instructive country in the world for seeing what water can do in cutting down the hardest rocks. Scrope's book is very good on the whole, though the pictures are a little overdone.

My wife and Leonard met me at Cologne on the 11th. Then we went on to Baden and rested till last Tuesday, when we journeyed to Luzerne and, getting out of that hot and unsavoury hole as fast as we could, came here last Thursday.

We find ourselves very well off. The hotel is perched up 1800 feet above the lake, with a beautiful view of Pilatus on the west and of the Urner See on the south. On the north we have the Schwyz valley, so that we are not shut in, and the air is very good and fresh. There are plenty of long walks to be had without much fatigue, which suits the wife. Leonard promises to have very good legs of his own with plenty of staying power. I have given him one or two sharp walks, and I find he has plenty of vigour and endurance. But he is not thirteen yet and I do not mean to let him do overmuch, though we are bent on a visit to a glacier. I began to tell him something about the glaciers the other day, but I was promptly shut up with, "Oh, yes! I know all about that. It's in Dr. Tyndall's book."—which said book he seems to me to have got by heart. He is the sweetest little fellow imaginable; and either he has developed immensely in the course of the last year, or I have never been so much thrown together with him alone, and have not had the opportunity of making him out.

You are a fatherly old bachelor, and will not think me a particularly great donkey for prattling on in this way about my swan, who probably to unprejudiced eyes has a power of goose about him.

I suppose you know that in company with yourself and Hooker, the paternal gander (T.H.H.) has been honoured by the King of Sweden and made into a Polar Goose by the order of the North Star. Hooker has explained to the Swedish Ambassador that English officials are prohibited by order in Council from accepting foreign orders, and I believe keeps the cross and ribbon on these conditions. If it were an ordinary decoration I should decline with thanks, but I am told it is a purely scientific and literary affair like the Prussian "pour le merite"; so when I get back I shall follow Hooker's line.
