In all other cases,
Either the sale is made of a certain and limited body,
Or it has as its object distinct and separate land,
Or it begins with the measure, or with the designation of the object sold followed by the measure,
The expression of this measure does not give rise to any additional price, in favour of the seller, for the excess measurement, nor in favour of the purchaser, to any reduction in the price for lesser measurement, only in so far as the difference between the actual measurement and that expressed in the contract is one-twentieth more or less, having regard to the value of the whole of the objects sold, if there is no stipulation to the contrary.
