The second quality of a price is, that the price be certain and determinate; but what may be rendered certain is considered as certain if, therefore, I sell a thing at a price to be fixed by a third person, this is sufficiently certain, provided the third person make a valuation and fix the price. Poth. Vente, n. 23, 24.
