Middlesex (560), a small county on the N. of the Thames, adjacent to and W. of London; has no hills and no rivers, only undulating pasture land and small streams. In 1888 the populous part next the metropolis was detached for the new county of London, leaving no big town but many suburban villages, Brentford, reckoned the county town, Harrow with its school, Highgate, and Hornsey. Hampton Court, Hampstead Heath, and Enfield Chase are in the county. There are many market gardens.
