There is a well-known story about the Chazon Ish, where someone who was scheduled to undergo a neurosurgical procedure came to him for advice, and the Chazon Ish drew a diagram for the surgeon indicating how the surgery should be performed. A few years ago I saw a copy of the diagram in a certain sefer, but can no longer remember where. Anyone know where it could be?
(If we find it, the next question will be who can interpret it!)
