I was reading a cricket history book that had some extracts from the 1755 'The Code of Laws of Cricket'. The below are a few of the additions to the original version from 1744. Some are pretty cool.
Laws for the Bowler
If he delivers ye Ball with his hinder foot over ye Crease ye Umpire shall call No Ball though he be struck or ye Player is bowled out, which he shall do without being asked and no Person shall have any right to ask him.
Laws for the Umpires
To allow two minutes for each man to come in when one is out and ten minutes between each hand. To mark ye Ball, that it may not be changed. They are sole judges of all Outs and Ins, of all Fair and Unfair play or frivolous delays, of all hurts whether real or pretended, and are discretionally to allow what time they think proper before the game goes on again. In case of a real hurt to a striker they are to allow another to come in & ye Person hurt to come in again. But are not to allow a fresh Man to play on either side on any account.
They are sole judges of all hindrances, crossing ye Players in running and standing unfair to strike and in case of hindrance may order a notch to be scored. They are not to order any Man out unless appealed to by any one of ye Players. These laws are to ye Umpires jointly.
Each Umpire is ye sole judge of all Nips and catches, Ins and Outs, good or bad runs at his own Wicket and his determination shall be absolute and he shall not be changed for another umpire without ye consent of both sides. When ye 4 balls are bowled, he is to call over.
When both umpires shall call Play, three times, 'tis at ye peril of giving Game from them that refuse to play.
