"Name, Situation, &c. - The origin of the name of Denny is unknown - The parish lies in the county and presbytery of Stirling and the synod of Perth and Stirling. - It is about 4 miles in length, 2½ in breadth. - The soil, about the town, or village of Denny, and indeed throughout the greater part o the parish, is dry and sandy; but in some places, it is wet, and has a good deal of clay in it. - The air is reckoned pure and healthy, and many of the people attain a good old age. Some, however, are much troubled with rheumatic complaints; and fevers frequently prevail, and are often fatal."
