Which chapter does James treat a sick and dying cow?

From the text:

I have a vivid recollection of a summer evening when I had to carry out a rumenotomy on a cow. As a rule I was inclined to play for time when I suspected a foreign body — there were so many other conditions with similar symptoms that I was never in a hurry to make a hole in the animal's side. But this time diagnosis was easy; the sudden fall in milk yield, loss of cudding; grunting, and the rigid, sunken-eyed appearance of the cow. And to clinch it the farmer told me he had been repairing a hen house in the cow pasture — nailing up loose boards. I knew where one of the nails had gone.
