25. An offer need not be made to an ascertained person, but no contract can arise until it has been accepted by an ascertained person.

In order that an offer may result in a contract it need not be made to a definitely ascertained person. It may be made to any one of the public generally, or to any one of a class of persons, who may accept it. These offers are sometimes said to be made "to all the world," but this is not correct.14 Take, for instance, the case of a proposal by way of advertisement of a reward for the rendering of certain services, addressed to the public at large, such as an advertisement for the return of lost property, or for the apprehension of persons who have committed a crime, or for certain information. This is an offer, to any one who shall accept it, of a promise for an act, and becomes a binding promise to pay the reward as soon as any individual renders the services.15

Offers of this character are generally advertisements for such services as we have mentioned, but they are not limited to them.16 Sellers of a medicinal remedy, who, to increase their sales, advertise

16 Seymour v. Armstrong, 62 Kan. 720, 64 Pac. 612. A published time table Is an offer by the railroad company to the public generally that, if they will apply for a ticket for carriage, they will be carried as stated in the time table, and the offer is accepted by each person who applies for a ticket. Denton v. Great Northern R. Co., 5 El. & Bl. 860; Sears v. Railroad Co., 14 Allen (Mass.) 433, 92 Am. Dee. 780. The same doctrine has been applied in the case of bounties offered by towns, cities, or counties to any person who should enlist into the military service of the United States. Crowell v. Hop-kinton, 45 N. II. 9. As to offers of premiums in horse races, see Alvord v. Smith, 68 Ind. 58. Offer by persons purchasing railroad on foreclosure and organizing new company to exchange new stock for old. Schorestene v. Ise-lin, 69 Hun, 250, 23 N. Y. Supp. 557. As to general letter of credit as being a general offer resulting in a promise to persons giving credit on the strength that a certain sum will be paid to any person who buys and uses the remedy, and afterwards contracts the disease it is claimed to prevent, will become bound by contract obligation to any person who purchases and uses the remedy, and he may recover the sum promised if he contracts the disease.17

Such a general offer may be made orally. Thus, where a person, whose wife was in a burning building, exclaimed to the bystanders generally that he would give a certain sum to any person who would bring out her body, and a man did so, it was held that he could recover the sum promised.18
