" The essentials of this contract are the identification of the parties contracting, the subject sold, and the amount of the price, and as regards these in the present case there is no room for doubt. The parties are certainly ascertained, the lands are sufficiently described in the missives, and the price is twenty-five years' purchase of the existing rental. As to the application of the price, the purchaser has no interest or concern, and nothing can be an essential of a contract which does not concern both the parties." Again, Lord Adam says,-" I have always understood that the essentials of a contract of sale are three, viz,, the person, the subject, and the price. If there is no error on these three points, then I understand there can be no relief against such a contract." And later on, after stating the nature of the error insisted on, he says,-" That is the error he avers, and from which he wants relief. Now, that is not an error which, to my mind, goes to the essentials of the contract at all. It appears to me to be simply this, that Sir Douglas Stewart understood that the price of from£300,000 to£400,000 should be disposed of in a particular way. Now, Mr Kennedy, the defender, the other party to the contract, has no concern with the application of the price, and therefore I cannot see how that can be an essential of the contract."
" If this plea were listened to, every litigant who is unsuccessful in a question as to the construction and effect, or, to use the pursuer's own words, ' the import and effect,' of a contract, would at once have the remedy of reducing the contract which he had deliberately made, and afterwards persistently misconstrued."
