then will sell it to him at a stipulated price, and in pursuance of that agreement I build a house, this may afford me ground for compelling
A to complete the purchase, but it certainly would afford no founda- tion for a claim by A to compel me to sell on the ground that I had partly performed the contract." On the other hand, possession given to the purchaser on the faith of an agreement to sell may operate SO as to make it a fraud on either party if the other repudiates

Other cases quoted in Maddison v. Alderson 2 I need not further mention, but in that case itself is found an important passage in Lord Selborne's judgment 3, as follows "It is not enough that an act done should be a condition of, or good consideration for, a contract, unless it is. as between the parties, such a part execution as to change their relative positions as to the subject matter of the contract."

Crystallizing that statement, for present purposes, there is always in part performance the actual transfer by enjoyment, directly or indirectly, of some right of ownership which the legal title
would confer. Maitland on Equity, at p. 242, brings the position to very much the same point.
In the early case of Butcher v. Stapely 4, referred to by Lord Selborne in Maddison v. Alderson 5, there are some suggestive words of the then Lord Chancellor quoted by Lord Selborne. Those words are: that in as much as possession was delivered according to the agreement, he took the bargain to be executed." Whether the suggestion that the equitable doctrine of part performance originated in the then well known, and up to a comparatively
