He was under the middle height; and his lower limbs were small in comparison with the upper, but neat and well-turned. His shoulders were very broad for his size; he had a face, in which energy and sensibility were remarkably mixed-up, an eager power checked and made patient by ill-health. Every feature was at once strongly cut, and delicately alive. If there was any faulty expression, it was in the mouth, which was not without something of a character of pugnacity... The head was a particular puzzle for the phrenologist, being remarkably small in the skull; a singularity he has in common with Lord Byron and Mr Shelley, none of whose hats I could get on.
John Keats
