tremity to Tottenham High Cross. (A small piece of Herts, contain- 

 ing the village of East Barnet, really forms part of this drainage 

 district.) 



The southern part of this district is quite suburban in character, the 

 northern portion was formerly open forest land, but is now all enclosed 

 and brought into cultivation. 



VII. Metropolitan. — N. the east of IV. from Kensal Green Station 

 to Highgate, and the south of VI., from Highgate to the county 

 boundary ; W. the east of V. ; S. that of the county from Hammer- 

 smith Bridge eastward ; E. that of the county from Tottenham High 

 Cross southward. 



This district is in no respect in a natural condition. The elevation, 

 drainage, and other physical conditions have been quite altered and 

 diverted, with the exception of a few places in the extreme north and 

 west of the district. It contains the ancient cities of London and 

 Westminster, and the greater part of the districts and parishes which 

 make up modem London.
