      Abstract of the Decision.
    1. Husband and wife, § 17
      
      —when person giving credit to wife has burden of showing liability of husband. Where husband and wife are living separate and apart, it devolves upon a physician giving credit to the wife for medical services to show that the wife was not at fault, or that the husband authorized or assented to the performance of the services.
    2. Husband and wife, § 18*—when evidence shows Knowledge by physician that wife is living apart from her husband. In an action by a physician for medical services furnished to the wife of defendant while she was living apart from her husband, where it appeared that plaintiff was called in to treat the wife by her mother and sister and that defendant was not consulted about a major operation, evidence held sufficient to show knowledge on the part of plaintiff that the wife was living apart from her husband.
    3. Husband and wife—what is effect of order for alimony pendente lite upon liability of husband for medical services. Where a husband and wife are living separate and apart, and there are separate maintenance proceedings pending in which there is an order for alimony pendente lite, and the husband is not in default on that order, he is not liable for medical services subsequently furnished during the pendency of the suit, and it is immaterial that the physician knows nothing about the litigation, since he is put on inquiry.
    4. Husband and wife, § 265*—who may not collaterally attack order as to alimony pendente lite in separate maintenance suit. The exercise by the trial court, in a separate maintenance suit, of its discretion in the awarding of alimony pendente lite cannot be collaterally drawn into question, especially by a stranger to the controversy, a physician, who contends in an action against the husband for medical services, that the amount of . alimony was so small that it was not intended to cover heavy medical expenses such as were incurred by the wife subsequent to the rendition of the order, since, if the wife is satisfied, no one else has the right to complain.
