To Heinrich Debus   Monday1

Monday.

My dear Heinrich.

Es thut mir Leid nicht gegenwartig zu sein als Du Deinen Vortrag hieltest.2 But as you say I needed Erfreschung3—and found it among the mountains. We had fine weather in Cumberland4—fine I say though we were sometimes in heavy snow. Sometimes in thick fog. but sometimes also in unclouded sunshine—the atmospheric changes were wonderful, and we climbed all the highest peaks.

I am now working hard at my book,5 and hope to make it a respectable one: I do not want it to pass away in a year, and hence while I try to write in a pleasant style and in a way which shall interest the general reader my aim also is to concentrate in it a solid body of Scientific truth.

Your estimate of Carlyle I think is a very correct one, and I am half tempted to send your letter6 to Mrs Carlyle, without letting her know any thing about its origin. I have looked over the first volume7 only and not the whole of that—but I shall read all someday.

I was sorry to hear of your cold and glad to hear of your industry. I have left south Audley Street & now live in a more open place near St. John’s Wood.8 I hope I may be able to pay you a visit during the spring or summer. Believe me it will give me pleasure to do so; but my book is now my first care.

This is a glorious day and it makes me long for the country—what a weight our civilization and social experiments lay upon our shoulders—and how I sometimes long to rid myself of the load, and to return to the free joyous life which I lived when a boy. Still it is only when the mind is weary that one feels them—Assuming the heart is strong enough to cope with, and were to enjoy the passages of civilization—

Goodbye Heinrich | Ever yours. J Tyndall

RI MS JT/1/T/327

[May or June]: This letter has been dated to May or June 1859 based on the reference to Tyndall’s recent visit to Cumberland and his move to lodgings in 31 Aberdeen Place, Maida Vale.

Es thut mir Leid nicht gegenwartig zu sein als Du Deinen Vortrag hieltest: I am sorry for not having been present when you gave your lecture.

Erfreschung: refreshment.

Cumberland: Tyndall visited the Cumberland mountains in April, see also letter 1608 for more details on this trip.

my book: likely refers to Glaciers of the Alps published in 1860.

your letter: letter missing.

the first volume: likely refers to Carlyle’s History of Friedrich II of Prussia: Called Fredrick the Great which was published in 6 volumes between 1858 and 1865.

I have left south Audley Street & now live in a more open place near St. John’s Wood: Tyndall moved to Maida Vale in May 1859.
