This is an appeal from a judgment on the pleadings entered in favor of defendant when plaintiff declined to plead further after a demurrer to his second amended complaint was sustained.

Plaintiff’s final pleading was entitled “Second Amended Complaint in Assumpsit.” The second amended complaint alleged in substance that Bobert Bobinson was the unemancipated minor son of plaintiff, living at plaintiff’s home and supported by him; that defendant obtained Bobert’s services by causing him to participate in a boxing smoker conducted on defendant’s premises; that Bobert suffered a fractured elbow in performing these services; that Bobert required medical treatment and hospitalization “to plaintiff’s damage in the sum of $675.00, whereby defendant became indebted to plaintiff for such sum”; that plaintiff made demand upon defendant to pay the same but defendant refused to do so and that as a consequence plaintiff suffered “property damage” in the sum of $675.00.

Under certain circumstances a person may recover in quasi contract for the interference with his right to *443the services of a third person. The rule is stated in Restatement, Restitution 552, § 135 (1937):

“A person who has tortiously obtained the services of a third person to which another is entitled aside from contract is under a duty of restitution to the person thereby deprived for the value of the services.”

The comment to § 135 explains that rule applies “to the case where a person obtains the services of an unemancipated minor child * * * to which the parent * * * is entitled, the services being obtained by means which are tortious as to the parent * * *. Thus it applies where a person entices away and employs a child knowing that the parent does not consent to such employment.” It is further noted in the comment that “The measure of restitution is not, as in an action of tort, the amount which the parent * * * has lost by the deprivation of the services, but the value of the services received, provided that the claimant was entitled to receive the land of services rendered.”

In the present case it is apparent that relief is sought on the theory of the existence of a contract implied in law as distinguished from a contract implied in fact. The complaint, to withstand demurrer, must, therefore, contain the elements set out in Restatement, Restitution § 135. There is nothing in the second amended complaint which can be regarded as an allegation that defendant obtained the services of the child by means which were tortious as to plaintiff.

The first amended complaint contained an allegation that the child’s services were obtained “without the consent of plaintiff or the mother of said minor.” This portion of the first amended complaint *444was stricken upon defendant’s motion. Plaintiff did not re-allege the matter in his second amended complaint. Assuming without deciding that the allegation is sufficient to charge defendant with tortious conduct in obtaining the services of plaintiff’s son, we are not concerned with it upon this appeal because plaintiff has not assigned as error the trial court’s action in striking it from the first amended complaint.① There is, therefore, no allegation that defendant tortiously obtained the services of Eobert. This being an essential element in plaintiff’s cause of action the demurrer was properly sustained.

The complaint is deficient in another respect. It is clear from the complaint that plaintiff does not seek to recover the value of the services to defendant but on the contrary seeks to recover expenditures made by him for medical and hospital costs. The quotation above from the Eestatement of Eestitution explains that the measure of restitution in quasi contract “is not, as in an action of tort, the amount which the *445parent * * * has lost by the deprivation of the services, but the value of the services received =* * =£ »

The complaint falls short of stating a cause of action in quasi contract. Therefore the demurrer to the complaint was properly sustained.

Judgment affirmed.
