From John Couch Adams   Sept. 29th 1862

Cambridge Observatory | Sept. 29^th 1862

Dear Dr. Tyndall,

I am sorry that you are not coming to us on Wednesday. I had accepted an invitation for you to dinner on that day. We would have been very moderate and would not have given you any reason to fear for the state of your nerves on Thursday.¹

I think as you have your preparations to make on Thursday morning, it will be most convenient for you to drive at once to my rooms at Pembroke College² and leave your things there. Then when your preparations are done, you can return there, and get ready for dinner, as we are going to dine with a friend a fellow of that College. The time of going to and returning from the Observatory will thus be saved, which is an object considering how little you allow yourself between your preliminary arrangements and the giving of your lecture.³

If you will tell me by what train you will come on Thursday, I will be at my rooms to meet you.

Believe me, | Yours very truly | J. C. Adams.
