"In consideration of your agreeing to allow the sum of 1000 l. (one thousand pounds) now held by the Commission to remain on deposit as a security for the due performance of this extended contract, the Commission hereby confirm the sale to you of the whole of the tentage which may become available in the United Kingdom for disposal up to and including March 31, 1923," upon the terms of the earlier contracts. The provision as to price is in these words: "
"It is understood that all disputes with reference to or arising out of this agreement will be submitted to arbitration in accordance with the provisions of the Arbitration Act, 1889."
"Certum est quod certum reddi potest."
"It is an option to offer terms on terms that are not agreed. An option to offer a contract which is not a contract seems to me not to carry the case any further than the first way of putting it."
