One afternoon when I was sitting alone in the smoking-room, Major Selby came in and limped to an armchair.

“Hullo, Major, have you got the gout again?” I asked jocosely.

“No, doctor; at least that pompous old beggar, Bell, says I haven’t.  My leg has been so confoundedly painful and stiff for the last few days that I went to see him this morning, but he told me that it was only a touch of rheumatism, and gave me some stuff to rub it with.”

“Oh, and did he look at your leg?”

“Not he.  He says that he can tell what my ailments are with the width of the street between us.”

“Indeed,” I said, and some other men coming in the matter dropped.

Four days later I was in the club at the same hour, and again Major Selby entered.  This time he walked with considerable difficulty, and I noticed an expression of pain and malaise upon his rubicund countenance.  He ordered a whisky and soda from the servant, and then sat down near me.

“Rheumatism no better, Major?” I asked.

“No, I went to see old Bell about it again yesterday, but he pooh-poohs it and tells me to go on rubbing in the liniment and get the footman to help when I am tired.  Well, I obeyed orders, but it hasn’t done me much good, and how the deuce rheumatism can give a fellow a bruise on the leg, I don’t know.”

“A bruise on the leg?” I said astonished.

“Yes, a bruise on the leg, and, if you don’t believe me, look here,” and, dragging up his trouser, he showed me below the knee a large inflamed patch of a dusky hue, in the centre of which one of the veins could be felt to be hard and swollen.

“Has Sir John Bell seen that?” I asked.

“Not he.  I wanted him to look at it, but he was in a hurry, and said I was just like an old woman with a sore on show, so I gave it up.”

“Well, if I were you, I’d go home and insist upon his coming to look at it.”

“What do you mean, doctor?” he asked growing alarmed at my manner.

“Oh, it is a nasty place, that is all; and I think that when Sir John has seen it, he will tell you to keep quiet for a few days.”

Major Selby muttered something uncomplimentary about Sir John, and then asked me if I would come home with him.

“I can’t do that as a matter of medical etiquette, but I’ll see you into a cab.  No, I don’t think I should drink that whisky if I were you, you want to keep yourself cool and quiet.”

So Major Selby departed in his cab and I went home, and, having nothing better to do, turned up my notes on various cases of venous thrombosis, or blood-clot in the veins, which I had treated at one time or another.

While I was still reading them there came a violent ring at the bell, followed by the appearance of a very agitated footman, who gasped out:—­

“Please, sir, come to my master, Major Selby, he has been taken ill.”
