(15) Over London ; the roar of London deep. 



(16) Koar of London loud and continuous. (17) The river Thames like a canal. " 

 (18) London looks very fine indeed. (19) Nearly over London Bridge. 



(20) The sunset is gorgeous ; rose-coloured cumuli extending from near the place of the 

 Sim to the S. and N. ; white cumuli in the E. ; no clouds except near the horizon. 



(21) The ships in the Thames appear long and narrow, and steamboats like moving toys 



(22) The Docks distinct and very clear. ^ 



(23) Can see the inner court of the Bank ; St. Paul's looks very small ; aU streets in the 

 city are distinctly visible ; Milbank Prison and Oxford Street seen very clearly 



(24) Over the Thames. " ^
