No, that was the Grimoire Speculorum, a volume in my private library. Written sanguinus humanorum on pellagra humanorum it is one of those little bibliographical finds, like the Necronomican (which I also have) one runs across from time to time. For example, in the GS there is this recipe for a form of Viagra:

Pluck the hairs from Ye testicles of Ye living Wolfe and boil in the blood of a chimera until they be dissolved. Boile into it ye fat from the kydneys of a hanged manne and continue in ye same manner until the potion be as thicke as butter. Make to dissolve a peece of this the size of a pea in a glass of wine and ye shall never be without a cockstand when wanted.

This lost me at the part about plucking the hairs from a wolf....

Would you have the enchantment to call up "ye demon Martinn Gibbsonn"?
