iDhabitants have been in the use to be served with potatoes from the 

 coast, water-borne, and sold with the water measure ; and that now of 

 late potatoes are planted in the neighbourhood, and brought into the city 

 for sale by country people who use diiferent measures, and less than the 

 water measure, and make thus mercat in many parts of the streets, and 

 before shop doors, and at the entry of closes ; and by these different 

 measures the inhabitants are imposed upon, and it being judged proper 

 that the place be ascertained where the potatoes are to be brought to for 

 sale, and all to be sold for the water measure ; therefore the magistrates 

 enact, that from and after the 8th October instant, the mercat-place for 

 the sale of potatoes be at the entry of the Candleriggs from the Trongate, 

 upon both sides of the street, to which place the inhabitants are to repair; 

 except as to potatoes sold at the Bromielaw, water-borne, and that no 

 mercat be made upon any of the parts of the streets, or entries of closes, 

 but the place above ascertained, and that all potatoes, whether water- 

 bortie or brought into the city from the country for sale, be sold by the 

 water measure, at the weighhouse, and no other measure certifying the 

 contraveners hereof, both sellers and buyers, that they will be fined, 

 punished, and the potatoes confiscate."
