In the last chapter we dealt with the mode in which the common intention of the parties must be communicated, and showed how it must refer to legal relations, in order that it may form the basis of a contract. It is not enough, however, that the common intention of the parties be communicated in the mode we have described, and that the parties intend legal consequences. Most systems of law require some further evidence of the intention of the parties, with out which mere intention will not avail to create an obligation between them. In our law this evidence is supplied by form and consideration. Sometimes one, sometimes the other, and sometimes both are required to render a contract enforceable. By "form" is meant some peculiar solemnity attaching to the expression of agreement; by "consideration," some gain to the party making the promise, arising from the act or forbearance, given or promised, of the promisee, or some detriment suffered by the promisee.1
