that he is at liberty to prove that such admissions were mistaken or
were untrue, and is not estopped or concluded by them, unless another person has been induced by them to alter his condition in such a case the party is estopped from disputing their truth with respect to that person (and those claiming under him), and that transaction. In Taylor on Evidence, 11th ed., at p. 564, par. 839, the rule is stated thus: " "Every admission, which has been made with the intention of being acted upon, and which has been acted upon by another person, is conclusive against the party making it, in all cases between him and the individual whose conduct he has thus influenced." In the absence of evidence that the appellant acted on the supposed admission, the respondents are not, in my opinion, debarred from asserting that Brady had no authority to give the undertaking sued on.
I think the appeal should be dismissed.

In the meantime, on 22nd December 1921, the Registrar- General lodged a caveat forbidding registration of any dealing (inter alia) not consistent with the duties of the executrix and executors of James Shepherd. On 22nd January 1923 there was a part payment of £1,000, on 3rd April a further part payment of £2,000 and on 28th April a third instalment of £1,000. This left £2,250 of principal still unpaid. On 9th August 1923 Norton, Smith &Co., who are the present respondents and were then acting as the vendors' solicitors, wrote to Williamson &Sons, the purchaser's that is, the appellant's, solicitors, setting out the state of the
