35. At common law, bills of exchange and promissory notes must be in writing.
(b) Acknowledgment of a debt barred by the statute of limitations.
(c) New promise by infant after attaining his majority.

In the preceding chapter we have dealt with those contracts which acquire validity by reason of their form alone, and we now pass to simple or parol contracts, which depend for their validity upon the presence of consideration. As we have seen, however, there are some simple contracts which, while not in the solemn form of a deed or record, are required by law to be in writing, and which, therefore, depend not only on the presence of consideration, as in the case of other simple or parol contracts, but also on their form. These contracts, in so far as their form is concerned, we shall deal with in the present chapter.
