“Some idea of the rapid motion of the blood may be formed from the following calculation: the heart propels, at each pulsation, about one ounce of blood, and when it makes eighty pulsations in a minute, of course three hundred pounds of blood must pass through it in an hour, which is about twelve times the whole mass of blood in the body; and this rapid action is incessantly going on, night and day, through life.” (Fuller on the Teeth, p. 47.)
