The third and fourth put a comma after the first ‘Richard,’ the third reading ‘devils,’ the fourth ‘devil’s.’ Rowe follows the Folios.

Pope has:

‘where is that Devil’s butcher,

Richard? hard-favour’d Richard, where art thou?’

Theobald:

‘where is that Devil-butcher,

Richard? hard-favour’d Richard, where art thou?’

Capell:

‘Where is that butcher, Richard?

Hard-favour’d Richard? Richard, where art thou?’
