The document discusses two cases regarding partnerships. In the first case, Z lent money to business partners X and Y in exchange for a share of profits but without mutual agency. The document concludes that Z is not a partner since mutual agency is lacking. In the second case, business partners X, Y, and Z agreed to a borrowing limit without consent but X borrowed excess from W. The document finds the firm liable to repay W if W was unaware of the limit, but not liable if W was aware.
