Every now and then doctors slap me about and ask me if I was always as thin as this.

"As thin as what?" I say with as much dignity as is possible to a man who has had his shirt taken away from him.

"As thin as this," says the doctor, hooking his stethoscope on to one of my ribs, and then going round to the other side to see how I am getting on there.

I am slightly better on the other side, but he runs his pencil up and down me and produces that pleasing noise which small boys get by dragging a stick along railings.

I explain that I was always delicately slender, but that latterly my ribs have been overdoing it.

"You must put on more flesh," he says sternly, running his pencil up and down them again. (He must have been a great nuisance as a small boy.)

"I will," I say fervently, "I will."

Satisfied by my promise he gives me back my shirt.

But it is not only the doctor who complains; Celia is even more upset by it. She says tearfully that I remind her of a herring. Unfortunately she does not like herrings. It is my hope some day to remind her of a turbot and make her happy. She, too, has my promise that I will put on flesh.

We had a fortnight's leave a little while ago, which seemed to give me a good opportunity of putting some on. So we retired to a house in the country where there is a weighing-machine in the bathroom. We felt that the mere sight of this weighing-machine twice daily would stimulate the gaps between my ribs. They would realize that they had been brought down there on business.
