Restoration of goods lent gratuitously.

The lender of a thing for use may at any time require

its return, if the loan was gratuitous, even though he lent it for a specified time or purpose. But if, on the

faith of such loan made for a specified time or purpose, the borrower has acted in such a manner that the

return of the thing lent before the time agreed upon would cause him loss exceeding the benefit actually

derived by him from the loan, the lender must, if he compels the return, indemnify the borrower for the

amount in which the loss so occasioned exceeds the benefit so derived.
