Omelette--Another Way

Break six eggs, leave out half the whites--beat them with a fork, and add some salt and chopped parsley; take four ounces of fresh butter, cut half of it in small pieces, put them in the omelette, put the other half in a small frying pan; when melted, pour in the eggs; stir till it begins to set, then turn it up round the edges; when done, put a plate on and turn the pan up, that it may not break--the omelette must be thick, and great care must be taken in frying; instead of parsley, you may use any kind of sweet herb or onion chopped fine, anchovy minced, rasped beef, ham or tongue.
