Quarter-plate. Golden yellow in the declining sun. There is a lightening conductor on the Tower. On the top storey but one are 8 columns of marble, very old and intricately carved. By a wooden ladder I then ascended to the top, which is roofed over. At four corners, stones about 2 ft [i.e. feet] square covered with incised lines, and let into stone frame-work. 2 of these inscribed stones remain, the other two slabs appear to have replaced older stones which have been removed.
