you might just as well as not be going out and getting material. You know damn well that I don't know how to go about such things, whereas you must have been an old hand at it before the earth was made. It's like you, you damned walking corpse, to start something you won't or can't finish!" Surama's evil chuckle came. "You're insane, Clarendon. That's the only reason I let you rave on when I could send you to hell in three minutes. Enough is enough, and you've certainly had enough material for any novice at your stage. You've had all I'm going to get you, anyhow! You're only a maniac on the subject now--what a cheap, crazy thing to sacrifice even your poor sister's pet dog, when you could have spared him as well as not! You can't look at any living thing now without wanting to jab that gold syringe into it. No--Dick had to go where the Mexican boy went--where Tsanpo and the other seven went--where all the animals went! What a pupil! You're no fun any more--you've lost your nerve.

Shub-Niggurath!" Through Clarendon's shrieking falsetto cut the deep chuckle of the clinic-man. "Shut up, you fool! Do you suppose your grotesque nonsense has any weight with me? Words and formulæ--words and formulæ--what do they all mean to one who has the substance behind them? We're in a material sphere now, and subject to material laws. You have your fever; I have my revolver. You'll get no specimens, and I'll get no fever so long as I have you in front of me with this gun between!" That was all Georgina could hear. She felt her senses reeling, and staggered out of the vestibule for a saving breath of the lowering outside air.
