"Mr. Butler. 'Very well. Where does the temporal artery take its rise in the system? Is it at the heart?'

"Witness. 'No, the aorta is the only artery leaving the heart which carries blood toward the head. Branches from it carry the blood up through the opening into the skull at the neck, and the temporal artery branches from one of these.'

"Mr. Butler. 'Doctor, where does it branch off from it? On the inside or the outside of the skull?'

"Witness. 'On the inside.'

"Mr. Butler. 'Does it have anything to do inside with supplying the brain?'

"Witness. 'No.'

"Mr. Butler. 'Well, doctor, how does it get outside to supply the head and temples?'

"Witness. 'Oh, it passes out through its appropriate opening in the skull.'

"Mr. Butler. 'Is that through the eyes?'

"Witness. 'No.'
