Read it through once

“Alan, I entreat you. Think of the position I am in. Just before you came I almost fainted with terror. You may know terror yourself some day. No! don’t think of that. Look at the matter purely from the scientific point of view. You don’t inquire where the dead things on which you experiment come from. Don’t inquire now. I have told you too much as it is. But I beg of you to do this. We were friends once, Alan.”
