to gain full possession of England

The Queen had already stooped towards the table, and placed the parchment before her, with the pen between her fingers, ready for the important act of signature. But when Lord Ruthven had done speaking, she looked up, stopped short, and threw down the pen. If, she said, I am expected to declare I give away my crown of free will, or otherwise than because I am compelled to renounce it by the threat of worse evils to myself and my subjects, I will not put my name to such an untruth — not to gain full possession of England, France, and Scotland!— all once my own, in possession, or by right.
Beware, madam, said Lindesay, and, snatching hold of the Queen’s arm with his own gauntleted hand, he pressed it, in the rudeness of his passion, more closely, perhaps, than he was himself aware of,—beware how you contend with those who are the stronger, and have the mastery of your fate!
He held his grasp on her arm, bending his eyes on her with a stern and intimidating look, till both Ruthven and Melville cried shame; and Douglas, who had hitherto remained in a state of apparent apathy, had made a stride from the door, as if to interfere. The rude Baron then quitted his hold, disguising the confusion which he really felt at having indulged his passion to such extent, under a sullen and contemptuous smile.
The Queen immediately began, with an expression of pain, to bare the arm which he had grasped, by drawing up the sleeve of her gown, and it appeared that his gripe had left the purple marks of his iron fingers upon her flesh —My lord, she said, as a knight and gentleman, you might have spared my frail arm so severe a proof that you have the greater strength on your side, and are resolved to use it — But I thank you for it — it is the most decisive token of the terms on which this day’s business is to rest.— I draw you to witness, both lords and ladies, she said, showing the marks of the grasp on her arm, that I subscribe these instruments in obedience to the sign manual of my Lord of Lindesay, which you may see imprinted on mine arm.
Lindesay would have spoken, but was restrained by his colleague Ruthven, who said to him, Peace, my lord. Let the Lady Mary of Scotland ascribe her signature to what she will, it is our business to procure it, and carry it to the Council. Should there be debate hereafter on the manner in which it was adhibited, there will be time enough for it.
