Aberdeen, Scotland.

Dear Professor Macleod:

I was very pleased to receive your note and the outline of the course for the Fourth Year B.&.M. option in Physiology. I am sure it will be a great help to me this year, and I intend to follow the outline fairly closely.
I was sorry not to be able to attend the meeting of the British Association, but my wife was taken suddenly ill just about the first of September, and I was not able to leave her. Happily, she improved rapidly, and we were able to sail on the twenty-first of September. We were afraid for some time that we would have to change our sailings.
After we left Aberdeen on our motor trip, we went to Strathpeffer, then to the West Coast, Strome Ferry, Dornoch and then south, as you suggested, to the Caledonia Canal. All of us thought that the part from Strathpeffer to the Caledonia Canal was by far the most beautiful of the whole trip. We consider ourselves very fortunate to have spoken to you about our route. After spending a day or two at Oban, we went through Glasgow to Ayr, and then south to North Wales, which we investigated very thoroughly. We then went through the Wye Valley to Tintern and then to Bath and
