"Halifax," he said; "I am the wretched victim of a demon—I often wish that I were dead!"

"I AM THE WRETCHED VICTIM OF A DEMON."

"You must fight the thing next time," I said. "It will be an awful struggle, I don't pretend to deny that; but I believe that you and I together will be a match for the enemy."

"It's awfully good of you to take me up—'pon my word it is."

"Well, is it a bargain?" I said.

"If you'll have it so."

"You must consider yourself my patient," I continued, "and obey me implicitly from this moment. It is most important that in the intervals of the attacks your health should be built up. I should recommend you to go to Switzerland, to take a sea voyage, or to do anything else which will completely brace the system. You should also cultivate your intellectual qualities, by really arduous study for a couple of hours daily."

"The thing I like best is music."

"Very well, study the theory of music. Don't weaken yourself over the sentimental parts. If you are really musical, and have taken it up as a pastime, work at the drudgery part for the next couple of months as if your bread depended on it. This exercise will put your brain into a healthy condition, and help to banish morbid thoughts. Then you must take plenty of exercise. If you go to Switzerland, you must do all the walking and the tobogganing which the weather will permit. If you go into the country, you must ride for so many hours daily. In short, it is your duty to get your body into training condition in order to fight your deadly enemy with any chance of success."
