23 Ainslie Place, August 26, 1867.
Dear Dr.Alexander--I have lately returned to Edinburgh, having paid a visit to my own country on Deeside.

On Saturday I drove down to Musselburgh, and had an express object in calling upon you to ask how you were.

But I found I had been wrong directed to Pinkie Burn, and that to accomplish my visit, I must have made a _detour_ which would have detained me too long.

I had an engagement waiting me, and I found my strength pretty well exhausted.
