- Description from The National Gazetteer (1868)
- Description from Barclay's Complete and Universal English Dictionary, 1842.)"A county of England, bounded by Hertfordshire, Essex, Surrey, Kent, and Buckinghamshire. It is one of the least counties in England, being only about 22 miles in length, and 14 in breadth. It contains 7 market towns, and about 98 parishes, without including those in London and Westminster. The air is healthy; but the soil in general being a lean gravel, it is naturally a district of little fertility, though by means of the vicinity to the metropolis, many parts of it are converted into rich beds of manure, clothed with almost perpetual verdure. Besides the Thames, the Lea, and the Coln, Middlesex is watered by several small streams, one of which, called the New River, is artificially brought from Amwell, in Hertfordshire, for the purpose of supplying London with water. Indeed, the whole county may be considered as a demesne to the metropolis, the land being laid out in gardens, pastures, and enclosures of all sorts, for its convenience and support. London is its chief place, and county town. Population, 1,576,636."
